abstract: Background : The increase in invasive fungal infections ( IFIs ) in neonatal intensive care unit ( NICU ) is jeopardizing the survival of preterm neonates . Probiotics modulating the intestinal microflora of preterm neonates may minimize enteral fungal colonization . Aims : This study was to examine whether probiotic supplementation in neonates reduced fungal septicemia . Material s and Methods : This prospect i ve , r and omized , double blind trial investigating the  supplementation of preterm infants with a probiotic  was done from May 2012 to April 2013 , with 112 subjects r and omized into two groups . Primary outcome : Decreased fungal colonization in gastrointestinal tract . Others : Incidence of late onset septicemia ; duration of the primary hospital admission ; number of days until full enteral feeds established . Results : Full feed establishment was earlier in probiotics group compared to placebo group ( P = 0.016 ) . The duration of hospitalization was less in the probiotic group ( P = 0.002 ) . Stool fungal colonization , an important outcome parameter was 3.03 ± 2.33 × 105 colony formation units ( CFU ) in the probiotics group compared to 3 ± 1.5 × 105 CFU in the placebo group ( P = 0.03 ) . Fungal infection is less in the study group ( P = 0.001 ) . Conclusion : The key features of our study were reduced enteral fungal colonization , reduce invasive fungal sepsis , earlier establishment of full enteral feeds , and reduced duration of hospital stay in the probiotics group BACKGROUND Probiotics are used for the prevention of necrotizing enterocolitis ( NEC ) because of their positive effects on intestinal motor function , modulation of inflammatory response , and mucosal barrier function . OBJECTIVE The objective was to assess whether the combined use of Lactobacillus casei and Bifidobacterium breve may prevent the occurrence of NEC stage ≥ 2 by the criteria of Bell in very-low-birth-weight preterm infants . DESIGN A double-blind , r and omized , controlled clinical trial was conducted in 231 preterm infants weighing from 750 to 1499 g at birth . The intervention group was composed of 119 infants who received human milk with probiotic supplementation ( B. breve and L. casei )  and a control group of 112 infants who received human milk containing no probiotics .  The primary outcome was the occurrence of NEC stage ≥ 2 as defined by Bell 's modified criteria . RESULTS Four confirmed cases of NEC stage ≥ 2 by Bell 's criteria occurred only in the control group . CONCLUSIONS Oral supplementation of B. breve and L. casei reduced the occurrence of NEC ( Bell 's stage ≥ 2 ) . It was considered that an improvement in intestinal motility might have contributed to this result . This trial was registered at www.is rct in.org as number 67165178 ( International St and ard R and omized Controlled Trial ) BACKGROUND Probiotics have strain specific effects and the effects of fungi in preventing diseases in preterm infants have been investigated poorly . Saccharomyces boulardii is a yeast which acts both as a probiotic and a polyamine producer . AIM The objective of this study was to investigate the efficacy of S. boulardii in preventing necrotizing enterocolitis ( NEC ) or sepsis in very low birth weight infants . STUDY DESIGN AND SUBJECTS A prospect i ve , double blind , placebo controlled trial was conducted in preterm infants ( ≤ 32 GWs , ≤ 1500 g birth weight ) . They were r and omized either to receive feeding supplementation with S. boulardii 50 mg/kg every 12 h or placebo , starting with the first feed until discharged . OUTCOME MEASURES Necrotizing enterocolitis ( NEC ) or sepsis and NEC or death . RESULTS Birth weight and gestational age of the study ( n = 104 ) and the control ( n = 104 ) groups were 1126 ± 232 vs 1162 ± 216 g and 28.8 ± 2.2 vs 28.7 ± 2.1 weeks , respectively . Neither the incidence of stage ≥ 2 NEC or death nor stage ≥ 2 NEC or late onset culture proven sepsis was significantly lower in the study group when compared with the control group ( 9.6 % vs 7.7 % , p = 0.62 ; 28.8 % vs 23 % , p = 0.34 ) . Time to reach 100 mL/kg/day of enteral feeding ( 11.9 ± 7 vs 12.6 ± 7 days , p = 0.37 ) was not different between the groups . CONCLUSIONS Saccharomyces boulardii did not decrease the incidence of NEC or sepsis ABSTRACT The gastrointestinal microbiota of preterm infants in a neonatal intensive care unit differs from that of term infants . In particular , the colonization of preterm infants by bifidobacteria is delayed . A double-blind , placebo-controlled , r and omized clinical study was performed on 69 preterm infants to investigate the role of Bifidobacterium lactis Bb12 supplementation in modifying the gut microbiota . Both culture-dependent and culture-independent approaches were used to study the gut microbiota . Bifidobacterial numbers , determined by fluorescence in situ hybridization , were significantly higher in the probiotic than in the placebo group ( log10 values per g of fecal wet weight : probiotic , 8.18 + 0.54 [ st and ard error of the mean ] ; placebo , 4.82 + 0.51 ; P < 0.001 ) . A similar trend for bifidobacterial numbers was also obtained with the culture-dependent method . The infants supplemented with Bb12 also had lower viable counts of Enterobacteriaceae ( log10 values of CFU per g of fecal wet weight : probiotic , 7.80 + 0.34 ; placebo , 9.03 + 0.35 ; P = 0.015 ) and Clostridium spp . ( probiotic , 4.89 + 0.30 ; placebo , 5.99 + 0.32 ; P = 0.014 ) than the infants in the placebo group . Supplementation of B. lactis Bb12 did not reduce the colonization by antibiotic-resistant organisms in the study population . However , the probiotic supplementation increased the cell counts of bifidobacteria and reduced the cell counts of enterobacteria and clostridia BACKGROUND It is known that the bifidobacteria flora play important roles in mucosal host defense and can prevent infectious diseases . Because bacterial population s develop during the first day of life , the authors examined whether the early administration of bifidobacteria has a positive effect on the health of low birth weight infants . METHODS The effects of oral administration of Bifidobacterium breve ( B. breve ) supplements were studied in a controlled trial with low birth weight infants ( average birth weight 1489 g ) . The infants were divided into three groups : Group A and B received a dose of 1.6 x 10(8 ) cells of B. breve supplement twice a day , commencing either from several hours after birth ( group A ) or 24 h after birth ( group B ) . Group C , the control group , received no supplement . RESULTS There were no significant differences in birth weight , treatment with antibiotics , and the starting time of breast-feeding among the three groups . A Bifidobacterium-predominant flora was formed at an average of 2 weeks after birth in group A and at an average of 4 weeks after birth in group B , while no Bifidobacterium was isolated in eight out of 10 infants in group C during the observation period of 7 weeks . In comparison between group A and B , Bifidobacterium was detected significantly earlier in group A , and the number of Enterobacteriaceae present in the infants at 2 weeks after birth was significantly lower in group A. CONCLUSION The results of the present study suggest that very early administration of B. breve to low birth weight infants is useful in promoting the colonization of the Bifidobacterium and the formation of a normal intestinal flora Objective : To evaluate the efficacy of probiotics in the prevention of gastrointestinal colonization by C and ida species , of late-onset sepsis and neurological outcome in preterm newborns . Study Design : A prospect i ve study was conducted in 249 preterms who were subdivided into three groups :  one group ( n=83 ) was supplemented with Lactobacillus ( L. ) reuteri , one group with L. rhamnosus ( n=83 ) and the other with no supplementation ( n=83 ) . The fungal colonization in the gastrointestinal tract , the late onset of sepsis and clinical parameters were recorded . A neurological structured assessment was further performed at 1 year of age . Result : C and ida stool colonization was significantly higher ( P<0.01 ) in the control group than in the groups treated with probiotics . The L. reuteri group presented a significantly higher reduction in gastrointestinal symptoms than did the L. rhamnosus and control groups . Infants treated with probiotics showed a statistically significant lower incidence of abnormal neurological outcome than did the control group . Conclusion : The use of both probiotics seems to be effective in the prevention of gastrointestinal colonization by C and ida , in the protection from late-onset sepis and in reducing abnormal neurological outcomes in preterms BACKGROUND AND OBJECTIVE : It has been suggested that probiotics may decrease  infant mortality and nosocomial infections because of their ability to suppress colonization and translocation of bacterial pathogens in the gastrointestinal tract . We design ed a large double-blinded placebo-controlled trial using Lactobacillus reuteri to test this hypothesis in preterm infants . METHODS : Eligible infants were r and omly assigned during the first 48 hours of life to either daily probiotic administration or placebo .  Infants in the intervention group were administered enterally 5 drops of a probiotic preparation containing 108 colony-forming units of L reuteri DSM 17938 until death or discharge from the NICU . RESULTS : A total of 750 infants ≤2000 g were enrolled . The frequency of the primary outcome , death , or nosocomial infection , was similar in the probiotic and placebo groups ( relative risk 0.87 ; 95 % confidence interval : 0.63–1.19 ; P = .376 ) . There was a trend toward a lower rate of nosocomial pneumonia in the probiotic group ( 2.4 % vs 5.0 % ; P = .06 ) and a nonsignificant 40 % decrease in necrotizing enterocolitis ( 2.4 % vs 4.0 % ; P = .23 ) . Episodes of feeding intolerance and duration of hospitalization were lower in infants ≤ 1500 g ( 9.6 % vs 16.8 % [ P = .04 ] ; 32.5 days vs 37 days [ P = .03 ] ) . CONCLUSIONS : Although L reuteri did not appear to decrease the rate of the composite outcome , the trends suggest a protective role consistent with what has been observed in the literature . Feeding intolerance and duration of hospitalization were decreased in premature infants ≤1500 Background : Nosocomial infections endanger preterm infants . Objective : The aim of the present controlled r and omized trial was to investigate whether Bifidobacterium lactis reduces the incidence of nosocomial infections in infants with very low birth weight ( VLBW ; < 1,500 g ) < 30 weeks of gestation . Patients and Methods : In a r and omized controlled trial , 183 VLBW infants < 30 weeks of gestation were stratified according to gestational age ( 23–26 and 27–29 weeks ) and early antibiotic therapy ( days 1–3 , yes or no ) and r and omly assigned to have their milk feedings supplemented with B. lactis ( 6 × 2.0 × 109 CFU/kg/day , 12 billion CFU/kg/day ) or placebo for the first 6 weeks of life . Primary outcome was the ‘ incidence density ’ of nosocomial infections defined as periods of elevated C-reactive protein ( > 10 mg/l ) from day 7 after initiation of milk feedings until the 42nd day of life ( number of nosocomial infections/total number of patient days ) . The main secondary outcome was necrotizing enterocolitis ( NEC ; ≧stage 2 ) . Results : There were 93 infants in the B. lactis group and 90 in the placebo group . There was no significant difference between the two groups with regard to the incidence density of nosocomial infections ( 0.021 vs. 0.016 ; p = 0.9 , χ2 test ) . There were 2 cases of NEC in the B. lactis group and 4 in the placebo group . None of the blood cultures grew B. lactis . Conclusion : In the present setting , B. lactis at a dosage of 6 × 2.0 × 109 CFU/kg/day ( 12 billion CFU/kg/day ) did not reduce the incidence density of nosocomial infections in VLBW infants . No adverse effect of B. lactis was observed BACKGROUND Probiotics may reduce  necrotising enterocolitis and late-onset sepsis after preterm birth . However , there has been concern about the rigour and generalisability of some trials and there is no agreement about whether or not they should be used routinely . We aim ed to test the effectiveness of the probiotic Bifidobacterium breve BBG-001 to reduce necrotising enterocolitis , late-onset sepsis , and death in preterm infants . METHODS In this multicentre , r and omised controlled phase 3 study ( the PiPS trial ) , we recruited infants born between 23 and 30 weeks ' gestational age within 48 h of birth from 24 hospitals in southeast Engl and . Infants were r and omly assigned ( 1:1 ) to probiotic or placebo via a minimisation algorithm r and omisation programme . The probiotic intervention was B breve BBG-001 suspended in dilute elemental infant formula given enterally in a daily dose of 8·2 to 9·2 log10 CFU ; the placebo was dilute infant formula alone . Clinicians and families were masked to allocation . The primary outcomes were necrotising enterocolitis ( Bell stage 2 or 3 ) , blood culture positive sepsis more than 72 h after birth ; and death before discharge from hospital . All primary analyses were by intention to treat . This trial is registered with IS RCT N , number 05511098 and EudraCT , number 2006 - 003445 - 17 . FINDINGS Between July 1 , 2010 , and July 31 , 2013 , 1315 infants were recruited ; of whom 654 were allocated to probiotic and 661 to placebo . Five infants had consent withdrawn after r and omisation , thus 650 were analysed in the probiotic group and 660 in the placebo group . Rates of the primary outcomes did not differ significantly between the probiotic and placebo groups . 61 infants ( 9 % ) in the probiotic group had necrotising enterocolitis compared with 66 ( 10 % ) in the placebo group ( adjusted risk ratio 0·93 ( 95 % CI 0·68 - 1·27 ) ; 73 ( 11 % ) infants in the probiotics group had sepsis compared with 77 ( 12 % ) in the placebo group ( 0·97 ( 0·73 - 1·29 ) ; and 54 ( 8 % ) deaths occurred before discharge home in the probiotic group compared with 56 ( 9 % ) in the placebo group ( 0·93 [ 0·67 - 1·30 ] ) . No probiotic-associated adverse events were reported . INTERPRETATION There is no evidence of benefit for this intervention in this population ; this result does not support the routine use of B breve BBG-001 for prevention of necrotising enterocolitis and late-onset sepis in very preterm infants . FUNDING UK National Institute for Health Research Health Technology Assessment programme OBJECTIVE The aim of this study was to compare the effect of administration of probiotics  on feeding tolerance and growth outcomes of HIV-exposed ( but uninfected ) versus HIV non-exposed preterm infants . The null hypothesis of this study states that there will be no difference in the feeding tolerance and growth outcomes for both probiotic-exposed and unexposed premature very low birth weight infants . METHODS A r and omized , double-blind , placebo-controlled trial was conducted during the period from July 2011 to August 2012 . HIV-exposed and non-exposed premature ( < 34 wk gestation ) infants with a birth weight of ≥500 g and ≤1250 g were r and omized to receive either a probiotic mixture or placebo . The multispecies probiotic mixture consisted of 1 × 10(9 ) CFU , Lactobacillus rhamnosus GG and Bifidobacterium infantis per day and was administered for 28 d. Anthropometrical parameters , daily intakes , and feeding tolerance were monitored . RESULTS Seventy-four HIV-exposed and 110 unexposed infants were enrolled and r and omized ( mean birth weight 987 g ± 160 g , range , 560 - 1244 g ; mean gestational age 28.7 wk ) . In all 4227 probiotic doses were administered ( mean 22.9/infant ) . There was no difference in the average daily weight gain for treatment groups or HIV exposure . The HIV-exposed group achieved significantly higher z scores for length and head circumference at day 28 than the unexposed group ( P < 0.01 and P = 0.03 , respectively ) . There were no differences in the incidence of any signs of feeding intolerance and abdominal distension between the groups . CONCLUSION Probiotic supplementation did not affect growth outcomes or the incidence of any signs of feeding intolerance in HIV exposure Objectives To assess the effect of the probiotic VSL#3 in prevention of neonatal sepsis in low birthweight ( LBW ) infants . Design R and omised , double-blind , placebo-controlled trial . Setting Community setting in rural India . Participants LBW infants aged 3–7 days . Interventions Infants were r and omised to receive probiotic ( VSL#3 , 10 billion colony-forming units ( cfu ) ) or placebo for 30 days , and were followed up for 2 months . Main outcome measure Possible serious bacterial infection ( PSBI ) as per the Integrated Management of Neonatal Childhood Illnesses algorithm , as diagnosed by fieldworkers/physicians . Results 668 infants were r and omised to VSL#3 and 672 to placebo .  By intention-to-treat analysis , the risk of PSBI among infants in the overall population of LBW infants was not statistically significant ( RR 0.79 ( 95 % CI 0.56 to 1.03 ) ) . Probiotics  reduced median days of hospitalisation ( 6 days vs 3 days in probiotics ) ( p=0.018 ) but not the risk of hospitalisation ( RR 0.66 ( 95 % CI 0.42 to 1.04 ) . The onset of PSBI in 10 % of infants occurred on the 40th day in the probiotics arm versus the 25th day in the control arm ( p=0.063 ) . Conclusions Daily supplementation of LBW infants with probiotics VSL#3 ( 10 billion cfu ) for 30 days led to a non-significant 21 % reduction in risk of neonatal sepsis . A larger study with sufficient power and a more specific primary end point is warranted to confirm the preventive effect of VSL#3 on neonatal sepsis in LBW infants . Trial registration number The study is registered at the Clinical Trial Registry of India ( CTRI/2008/091/000049 ) BACKGROUND AND OBJECTIVE : Late-onset sepsis frequently complicates prematurity , contributing to morbidity and mortality . Probiotics may reduce mortality and necrotizing enterocolitis ( NEC ) in preterm infants , with unclear effect on late-onset sepsis . This study aim ed to determine the effect of administering a specific combination of probiotics to very preterm infants on culture-proven late-onset  sepsis . METHODS : A prospect i ve multicenter , double-blinded , placebo-controlled , r and omized trial compared daily administration of a probiotic combination ( Bifidobacterium infantis , Streptococcus thermophilus , and Bifidobacterium lactis , containing 1 × 109 total organisms ) with placebo ( maltodextrin ) in infants born before 32 completed weeks ’ gestation weighing < 1500 g. The primary outcome was at least 1 episode of definite late-onset sepsis . RESULTS : Between October 2007 and November 2011 , 1099 very preterm infants from Australia and New Zeal and were r and omized . Rates of definite late-onset sepsis ( 16.2 % ) , NEC of Bell stage 2 or more ( 4.4 % ) , and mortality ( 5.1 % ) were low in controls , with high breast milk feeding rates ( 96.9 % ) . No significant difference in definite late-onset sepsis or all-cause mortality was found , but this probiotic combination reduced NEC of Bell stage 2 or more ( 2.0 % versus 4.4 % ; relative risk 0.46 , 95 % confidence interval 0.23 to 0.93 , P = .03 ; number needed to treat 43 , 95 % confidence interval 23 to 333 ) . CONCLUSIONS : The probiotics B infantis , S thermophilus , and B lactis significantly reduced NEC of Bell stage 2 or more in very preterm infants , but not definite late-onset sepsis or mortality . Treatment with this combination of probiotics appears to be safe Background A r and omised , double-blind clinical trial was undertaken in order to assess the effectiveness of probiotics in the prevention of  necrotising enterocolitis ( NEC ) in newborns weighing < 1500 g. Methods We studied a group of 150 patients who were r and omised in two groups after parental consent was obtained , to receive either a daily feeding supplementation with a multispecies probiotic ( Lactobacillus acidophilus , Lactobacillus rhamnosus , Lactobacillus casei , Lactobacillus plantarum , Bifidobacteruim infantis , Streptococcus thermophillus ) 1 g per day plus their regular feedings or to receive their regular feedings with nothing added ( control group ) , over the period of January 2007 through June 2010 . Clinicians in care of the infants were blinded to the group assignment . Results The primary outcome was the development of NEC . Both groups were comparable , with no differences during hospitalisation , including the type of nutrition received . Blood cultures obtained from cases that developed sepsis did not reveal lactobacillus or Bifidobacteria growth . No differences were detected in terms of NEC risk reduction ( RR : 0.54 , 95 % CI 0.21 to 1.39 ) although we did observe a clear trend in the reduction of NEC frequency in the studied cases : 6 ( 8 % ) versus 12 ( 16 % ) in the control group . When the combined risk of NEC or death was calculated as a post hoc analysis , we found a significantly lower risk ( RR : 0.39 , 95 % CI 0.17 to 0.87 ) for the study group . Conclusions Probiotics may offer potential benefits for premature infants and are a promising strategy in the reduction of the risk of NEC in preterm newborns BACKGROUND Saccharomyces boulardii ( SB ) is a yeast that acts both as a probiotic and as a polyamine producer . Probiotics prevent the overgrowth of pathogens in the gut while polyamines enhance intestinal maturation . The aim of this r and omized study was to investigate the ability of SB to modify the gut microbial ecology and its function . METHODS A total of 87 healthy babies with gestational age 28 - 32 weeks were studied . They were r and omly assigned to receive a preterm formula to which SB or maltodextrins was added for 30 days . Evaluations were made on the following : SB tolerance and weight gain , faecal flora analysis , intestinal D-xylose absorption and faecal lipid excretion . RESULTS SB was well tolerated by the infants . There was no difference in weight gain between the two groups . Median log of colony forming units per gram of faeces for Escherichia coli and enterococci was significantly lower in the SB group [ E. coli : 2.67 ( 0.045 ) vs. 2.75 ( 0.058 ) , P<0.001 ; enterococci : 2.14 ( 0.359 ) vs. 2.19 ( 0.138 ) , P<0.05 ] . On the other h and , the number of bifidobacteria and staphylococci in the stools was significantly higher in the SB group [ bifidobacteria : 2.65 ( 0.083 ) vs. 2.27 ( 0.075 ) , P<0.001 ; staphylococci : 1.23 ( 0.869 ) vs. 0.6 ( 0.281 ) , P<0.001 ] . D-Xylose and lipid absorption was not improved by SB [ median blood D-xylose : 1.5 ( 0.4 ) mmol/l vs. 1.35 ( 0.3 ) mmol/l , P>0.1 ; median stool steatocrit : 64 % ( 3.05 % ) vs. 65 % ( 2.72 % ) P>0.5 ] . CONCLUSIONS An SB-supplemented formula is well tolerated by preterm infants , it has a beneficial effect on stool flora bringing it closer to that of breast fed babies but it does not improve D-xylose or lipid gut absorption Objective To evaluate the effect of oral Lactobacillus reuteri ( L reuteri ) first on the incidence and severity of Necrotising enterocolitis ( NEC ) and second on sepsis . Design Prospect i ve r and omised controlled study . Setting Tertiary neonatal intensive care unit . Patients and interventions Preterm infants with a gestational age of ≤32 weeks and a birth weight of ≤1500 g were included ( n=400 ) . Infants in the first group were given 100 million CFU/day ( 5 drops ) of lyophilised L reuteri ( DSM 17938 ) mixed in breast milk or formula , starting from first feeding until discharge . Participants in the control group were given a placebo . Main outcome measures To determine and compare the frequency of NEC and /or death after 7 days , frequency of proven sepsis , rates of feeding intolerance and duration of hospital stay . Results There was no statistically significant difference between groups in terms of frequency of NEC stage ≥2 ( 4 % vs 5 % ; p=0.63 ) or overall NEC or mortality rates ( 10 % vs 13.5 % ; p=0.27 ) . Frequency of proven sepsis was significantly lower in the probiotic group compared to the control group ( 6.5 % vs 12.5 % ; p=0.041 ) . A significant difference was also observed with regard to rates of feeding intolerance ( 28 % vs 39.5 % ; p=0.015 ) and duration of hospital stay ( 38 ( 10–131 ) vs 46 ( 10–180 ) days ; p=0.022 ) . Conclusions Our results show that oral L reuteri does not seem to affect the overall rates of NEC and /or death in preterm infants followed up in the neonatal intensive care unit , and significant reductions were observed in the frequency of proven sepsis , rates of feeding intolerance and duration of hospital stay . Trial registration number NCT01531179 Background Probiotic supplementation significantly reduces the risk of necrotising enterocolitis ( NEC ) and all cause mortality  in preterm neonates . Independent quality assessment is important before introducing routine probiotic supplementation in this cohort . Aim To assess product quality , and confirm that Bifidobacterium breve ( B. breve ) M-16V supplementation will increase fecal B. breve counts without adverse effects . Methods and Participants Strain identity ( 16S rRNA gene sequencing ) , viability over 2 year shelf-life were confirmed , and microbial contamination of the product was ruled out . In a controlled trial preterm neonates ( Gestation <33 weeks ) ready to commence or on feeds for < 12 hours were r and omly allocated to either B. breve M-16V ( 3 × 109 cfu/day ) or placebo ( dextrin ) supplementation  until the corrected age 37 weeks . Stool sample s were collected before ( S1 ) and after 3 weeks of supplementation ( S2 ) for study ing fecal B. breve levels using quantitative PCR ( Primary outcome ) . Secondary outcomes included total fecal bifidobacteria and NEC≥Stage II . Categorical and continuous outcomes were analysed using Chi-square and Mann-Whitney tests , and McNemar and Wilcoxon signed-rank tests for paired comparisons . Results A total of 159 neonates ( Probiotic : 79 , Placebo : 80 ) were enrolled . Maternal and neonatal demographic characteristics were comparable between the groups . The proportion of neonates with detectable B. breve increased significantly post intervention : Placebo : [ S1:2/66 ( 3 % ) , S2 : 25/66 ( 38 % ) , p<0.001 ] Probiotic : [ S1 : 29/74 ( 40 % ) , S2 : 67/74 ( 91 % ) , p<0.001 ] . Median S1 B. breve counts in both groups were below detection ( < 4.7 log cells.g−1 ) , increasing significantly in S2 for the probiotic group ( log 8.6 ) while remaining < 4.7 log in the control group ( p<0.001 ) . There were no adverse effects including probiotic sepsis and no deaths . NEC≥Stage II occurred in only 1 neonate ( placebo group ) . Conclusion B. breve M-16V is a suitable probiotic strain for routine use in preterm neonates . Trial Registration Australia New Zeal and Clinical Trial Registry ACTRN OBJECTIVE . The goal was to investigate the efficacy of orally administered probiotics in preventing necrotizing enterocolitis for very low birth weight preterm infants . METHODS . A prospect i ve , blinded , r and omized , multicenter controlled trial was conducted at 7 NICUs in Taiwan , to evaluate the beneficial effects of probiotics in necrotizing enterocolitis among very low birth weight infants ( birth weight : < 1500 g ) . Very low birth weight infants who survived to start enteral feeding were eligible and were assigned r and omly to 2 groups after parental informed consent was obtained . Infants in the study group were given Bifidobacterium bifidum and Lactobacillus acidophilus , added to breast milk or mixed feeding ( breast milk and formula ) , twice daily for 6 weeks . Infants in the control group were fed with breast milk or mixed feeding . The clinicians caring for the infants were blinded to the group assignment . The primary outcome measurement was death or necrotizing enterocolitis ( Bell 's stage ≥2 ) . RESULTS . Four hundred thirty-four infants were enrolled , 217 in the study group and 217 in the control group . The incidence of death or necrotizing enterocolitis ( stage ≥2 ) was significantly lower in the study group ( 4 of 217 infants vs 20 of 217 infants ) . The incidence of necrotizing enterocolitis ( stage ≥2 ) was lower in the study group , compared with the control group ( 4 of 217 infants vs 14 of 217 infants ) . No adverse effect , such as sepsis , flatulence , or diarrhea , was noted . CONCLUSION . Probiotics , in the form of Bifidobacterium and Lactobacillus , fed enterally to very low birth weight preterm infants for 6 weeks reduced the incidence of death or necrotizing enterocolitis OBJECTIVE To evaluate the health benefits of an exclusively human milk-based diet compared with a diet of both human milk and bovine milk-based products in extremely premature infants . STUDY DESIGN Infants fed their own mothers ' milk were r and omized to 1 of 3 study groups . Groups HM100 and HM40 received pasteurized donor human milk-based human milk fortifier when the enteral intake was 100 and 40 mL/kg/d , respectively , and both groups received pasteurized donor human milk if no mother 's milk was available . Group BOV received bovine milk-based human milk fortifier when the enteral intake was 100 mL/kg/d and preterm formula if no mother 's milk was available . Outcomes included duration of parenteral nutrition , morbidity , and growth . RESULTS The 3 groups ( total n = 207 infants ) had similar baseline demographic variables , duration of parenteral nutrition , rates of late-onset sepsis , and growth . The groups receiving an exclusively human milk diet had significantly lower rates of necrotizing enterocolitis ( NEC ; P = .02 ) and NEC requiring surgical intervention ( P = .007 ) . CONCLUSIONS For extremely premature infants , an exclusively human milk-based diet is associated with significantly lower rates of NEC and surgical NEC when compared with a mother 's milk-based diet that also includes bovine milk-based products The objectives of this study were to determine whether or not the probiotic Lactobacillus GG can colonise the immature bowel of premature infants and if so , does colonisation result in a reduction of the size of the bowel reservoir of nosocomial pathogens such as enterobacteriaceae , enterococci , yeasts or staphylococci , and does colonisation with Lactobacillus GG have any effect on the clinical progress and outcome . Twenty preterm infants with a gestational age of 33 weeks or less who were resident on a neonatal unit were studied from the initiation of milk feeds until discharge . The infants were r and omised to receive either milk feeds or milk feeds supplemented with Lactobacillus GG 10(8 ) colony forming units twice a day for two weeks . The clinical features of the two groups of infants were similar . Orally administered Lactobacillus GG was well tolerated and did colonise the bowel of premature infants . However , colonisation with Lactobacillus GG did not reduce the faecal reservoir of potential pathogens and there was no evidence that colonisation had any positive clinical benefit for this particular group of infants BACKGROUND OF THE STUDY Preterm infants are managed with antibiotics for sepsis , including suspected or probable sepsis . This leads to a delayed and abnormal colonization of the gut with potentially pathogenic organisms and a microbiome , which lacks biodiversity and increases the risk for late-onset sepsis ( LOS ) . Probiotics have been proven to reduce the risk for necrotizing enterocolitis , but evidence for prevention of LOS is inconclusive . Probiotic effect depends also on the strain used , dose and indication for use . This study evaluated Bacillus clausii probiotic administered prophylactically to preterm neonates for prevention of LOS . OBJECTIVES To study B.clausii given prophylactically to preterm neonates for prevention of LOS . DESIGN Double-blinded , placebo-controlled , r and omized trial . SETTING S Tertiary care neonatal unit in India . PARTICIPANTS Consecutive preterm neonates < 34 weeks , admitted from 1 March 2012 to 28 February 2014 were stratified as extreme preterm and very preterm . INTERVENTION R and omized to receive either probiotic or placebo for 6 weeks , discharge from hospital , death or occurrence of sepsis , whichever was earlier . PRIMARY OUTCOME Incidence of definite and probable LOS in probiotic group compared with placebo . RESULTS Of 326 eligible preterm infants , 244 were enrolled and 82 were excluded . Of these , 120 were stratified as extreme preterm and r and omized to receive placebo ( n = 59 ) and probiotic ( n = 61 ) . Of 124 babies stratified as very preterm , an equal number was r and omized to receive placebo ( n = 62 ) and probiotic ( n = 62 ) . There was no significant difference in the incidence of LOS between the two arms in the extreme preterm group [ 29 % vs. 23 % ; relative risk ( RR ) 1.27 ; 95 % confidence interval ( CI ) 0.88 - 1.66 ; p = 0.36 ] and the very preterm group ( 13 % vs. 10 % ; RR 1.33 ; 95 % CI 0.96 - 1.70 ; p = 0.32 ) . Full feeds were achieved significantly faster in the probiotic group in both the extreme preterm ( RR 0.82 ; 95 % CI 0.74 - 0.88 ) and the very preterm ( RR 0.67 ; 95 % 0.32 - 0.77 ) . CONCLUSIONS Prophylactic administration of B.clausii to preterm neonates did not result in a significant difference in the incidence of LOS as compared with placebo Background : The interrelations between early enteral feeding , necrotising enterocolitis ( NEC ) , and nosocomial sepsis ( NS ) remain unclear . Objective : To evaluate the effect of age at the introduction of enteral feeding on the incidence of NS and NEC in very low birthweight ( VLBW < 1500 g ) infants . Methods : Data were collected on the pattern of enteral feeding  and perinatal and neonatal morbidity on all VLBW infants born in one centre during 1995–2001 .  Enteral feeding was compared between infants with and without NS and /or NEC . Results : The study sample included 385 infants . Of these , 163 ( 42 % ) developed NS and 35 ( 9 % ) developed NEC .  Enteral feeding was started at a significantly earlier mean ( SD ) age in infants who did not develop nosocomial sepsis ( 2.8 ( 2.6 ) v 4.8 ( 3.7 ) days , p = 0.0001 ) . Enteral feeding was introduced at the same age in babies who did or did not develop NEC ( 3.1 ( 2 ) v 3.7 ( 3 ) days , p = 0.28 ) . Over the study period , the mean annual age at the start of enteral feeding fell consistently , and this correlated with the mean annual incidence of NS ( r2 = 0.891 , p = 0.007 ) . Multiple logistic regression analysis showed age at start of enteral feeding , respiratory distress syndrome , and birth weight to be the most significant predictors of risk of NS ( p = 0.0005 , p = 0.024 , p = 0.011 ) . Conclusions : Early enteral feeding was associated with a reduced risk of NS but no change in the risk of NEC  in VLBW infants . These findings support the use of early enteral feeding in this high risk population , but this needs to be confirmed in a large r and omised controlled trial BACKGROUND Preterm infants have increased intestinal permeability which can render them susceptible to infections from enterobacteriae . OBJECTIVES The primary objective was to investigate whether probiotic administration to preterm infants decreases intestinal permeability . Secondary outcomes studied were : somatic growth , tolerance , rates of sepsis and necrotizing enterocolitis . METHODS In a prospect i ve r and omized case-control study 41 stable preterm infants of 27 to 36 weeks gestation and 34 matched comparison infants consecutively admitted to the neonatal unit were studied . The study group received a preterm formula supplemented with Bifidobacter lactis ( 2 x 10(7 ) cfu/g of dry milk ) while the control group received the same formula but without supplementation .  Intestinal permeability was measured within two days of birth and then seven and thirty days later using the sugar absorption test . Additionally anthropometric parameters were recorded throughout the study as well as acceptance and tolerance of the formula . RESULTS All infants tolerated the study formula well . Median counts of stool bifidobacteria and lactulose/mannitol ratios at baseline were comparable . After 7 days of supplementation median bifidobacteria counts were significantly higher in the study group than in the control group ( p=0.0356 ) and they remained higher to the end of the study ( p at day 30=0.075 ) . The L/M ratio in the study group was significantly lower at day 30 of the study as compared to the control group ( p=0.003 ) . Head growth was significantly higher in the study group ( p=0.001 ) . CONCLUSIONS The administration of a bifidobacter supplemented infant formula decreases intestinal permeability of preterm infants and leads to increased head growth OBJECTIVE To evaluate the effect of oral administration of probiotics on intestinal colonization with drug-resistant bacteria among preterm infants in the neonatal intensive care unit ( NICU ) . METHODS A double-blind , r and omized , placebo-controlled trial was carried out in the preterm infants who were transferred to the NICU immediately after birth . These infants were stratified by whether they were breastfed and then r and omized into test group and control group . The test group was given probiotics from the day when enteral feeding began , while the control group was treated conventionally without probiotics . The two groups were compared in terms of the colonization with extended-spectrum beta-lactamase-producing bacteria , as assessed by rectal swabs on days 1 , 3 , 7 , and 14 after birth , and the incidence of diseases . RESULTS Rectal colonization with drug-resistant bacteria was found in the test group ( n=119 ) and control group ( n=138 ) on days 1 , 3 , 7 , and 14 after birth . There were no significant differences in the incidence of late-onset sepsis and necrotizing enterocolitis between the two groups ( P>0.05 ) . Among non-breastfed infants , the test group had significantly decreased rectal colonization with drug-resistant bacteria compared with the control group on day 14 after birth ( 71.1 % vs 88.9 % ; P=0.04 ) . No probiotic-related adverse events were observed in the study . CONCLUSIONS Oral administration of probiotics may reduce rectal colonization with drug-resistant bacteria in preterm infants under certain conditions and shows good safety Studies were carried out on premature infants in the neonatal intensive care unit to determine the effect of feeding of lactobacilli on colonization of the gastrointestinal tract by antibiotic-resistant gram-negative enteric organisms . Thirty premature infants were matched by birth weight and gestational age , r and omized and fed double blind either lactobacilli-containing formula or non-lactobacilli-containing formula within 72 hours of delivery . The two study groups were screened weekly by culture for stool lactobacilli , for gram-negative bacteria and for antibiotic resistance of these bacteria .  Lactobacilli  were cultured from the stools of 13 of 15 patients receiving lactobacilli and from 3 of 15 patients not receiving lactobacilli ( P < 0.001 ) . Gram-negative enteric organisms were isolated during 40 of the 86 weeks ( 47 % ) of hospitalization for patients receiving lactobacilli and during 28 of 57 weeks ( 49 % ) for patients not receiving lactobacilli . There was no significant difference between the study groups in the number of resistant organisms or in the proportion of resistant organisms per gram-negative enteric isolates ( 4 of 40 vs. 0 of 28 ) . These results suggest that facultative gram-negative enteric bacterial colonization , with either total or aminoglycoside-resistant strains , is not decreased by oral feedings of Lactobacillus acidophilus in premature infants Background : It has been suggested that probiotics can reduce the overgrowth of pathogens in the bowels of preterm infants and contribute to the reduction of the incidence of nosocomial infections in neonatal intensive care units ( NICUs ) . The purpose of this study was to evaluate the effectiveness of Lactobacillus GG supplementation in reducing the incidence of urinary tract infections ( UTIs ) , bacterial sepsis and necrotizing enterocolitis ( NEC ) in preterm infants . Methods : A double-blind study was conducted in 12 Italian NICUs . Newborn infants with a gestational age <33 weeks or birthweight < 1,500 g were r and omized to receive st and ard milk feed supplemented with Lactobacillus GG ( Dicoflor ® , Dicofarm , Rome , Italy ) in a dose of 6 × 109 colony-forming units ( cfu ) once a day until discharge , starting with the first feed or placebo . Results : Five hundred eighty-five patients were studied . The probiotics group ( n = 295 ) and the placebo group ( n = 290 ) exhibited similar clinical characteristics . The duration  of Lactobacillus GG and placebo supplementation was 47.3 ± 26.0 and 48.2 ± 24.3 days , respectively . Although UTIs ( 3.4 vs. 5.8 % ) and NEC ( 1.4 vs. 2.7 % ) were found less frequently in the probiotic group compared to the control group , these differences were not significant . Bacterial sepsis was more frequent in the probiotics group ( 4.4 % , n = 11 ) than in the placebo group ( 3.8 % , n = 9 ) , but the difference was not significant . Conclusion : Seven days of Lactobacillus GG supplementation starting with the first feed is not effective in reducing the incidence of UTIs , NEC and sepsis in preterm infants . Further studies are required to confirm our results in lower birthweight population Objective : The objective of this trial was to test whether probiotic-supplemented feeding to extremely low-birth-weight ( ELBW ) infants will improve growth as determined by decreasing the percentage of infants with weight below the 10th percentile at 34 weeks postmenstrual age ( PMA ) . Other important outcome measures , such as improving feeding tolerance determined by tolerating larger volume of feeding per day and reducing antimicrobial treatment days during the first 28 days from the initiation of feeding supplementation were also evaluated . Study Design : We conducted a multicenter r and omized controlled double-blinded clinical study . The probiotics-supplementation ( PS ) group received Lactobacillus rhamnosus GG and Bifidobacterium infantis added to the first enteral feeding and continued once daily with feedings thereafter until discharge or until 34 weeks ( PMA ) . The control ( C ) group received unsupplemented feedings .  Infant weight and feeding volumes were recorded daily during the first 28 days of study period . Weights were also recorded at 34 weeks PMA . Result : A total of 101 infants were enrolled ( PS 50 versus C 51 ) . There was no difference between the two groups in the percentage of infants with weight below the 10th percentile at 34 weeks PMA ( PS group 58 % versus C group 60 % , ( P value 0.83 ) ) or in the average volume of feeding during 28 days after study entry ( PS group 59 ml kg−1 versus C group 71 ml kg−1 , ( P value 0.11 ) ) . Calculated growth velocity was higher in the PS group compared with the C group ( 14.9 versus 12.6 g per day , ( P value 0.05 ) ) . Incidences of necrotizing enterocolitis ( NEC ) , as well as mortality were similar between the two groups . Conclusion : Although probiotic-supplemented feedings improve growth velocity in ELBW infants , there was no improvement in the percentage of infants with growth delay at 34 weeks PMA . There were no probiotic-related adverse events reported BACKGROUND Colonization by C and ida species is the most important predictor of the development of invasive fungal disease in preterm neonates , and the enteric reservoir is a major site of colonization . We evaluated the effectiveness of an orally supplemented probiotic ( Lactobacillus casei subspecies rhamnosus ; Dicoflor [ Dicofarm spa ] ; 6 x 10(9 ) cfu/day ) in the prevention of gastrointestinal colonization by C and ida species in preterm , very low birth weight ( i.e. , < 1500-g ) neonates during their stay in a neonatal intensive care unit . METHODS Over a 12-month period , a prospect i ve , r and omized , blind , clinical trial that involved 80 preterm neonates with a very low birth weight was conducted in a large tertiary neonatal intensive care unit . During the first 3 days of life , the neonates were r and omly assigned to receive either an oral probiotic added to human ( maternal or pooled donors ' ) milk ( group A ) or human milk alone ( group B ) for 6 weeks or until discharge from the NICU , if the neonate was discharged before 6 weeks . On a weekly basis , specimens obtained from various sites ( i.e. , oropharyngeal , stool , gastric aspirate , and rectal specimens ) were collected from all patients for surveillance culture , to assess the occurrence and intensity of fungal colonization in the gastrointestinal tract . RESULTS The incidence of fungal enteric colonization ( with colonization defined as at least 1 positive culture result for specimens obtained from at least 1 site ) was significantly lower in group A than in group B ( 23.1 % vs. 48.8 % ; relative risk , 0.315 [ 95 % confidence interval , 0.120 - 0.826 ] ; P = .01 ) . The numbers of fungal isolates obtained from each neonate ( P = .005 ) and from each colonized patient ( P = .005 ) were also lower in group A than in group B. L. casei subspecies rhamnosus was more effective in the subgroup of neonates with a birth weight of 1001 - 1500 g. There were no changes in the relative proportions of the different C and ida strains . No adverse effects potentially associated with the probiotic were recorded . CONCLUSIONS Orally administered L. casei subspecies rhamnosus significantly reduces the incidence and the intensity of enteric colonization by C and ida species among very low birth weight neonates Background / Objective : The identification of probiotic species involved in gut homeostasis and their potential therapeutic benefits have led to an interest in their use for preventing necrotizing enterocolitis ( NEC ) . Although bifidobacterium and lactobacilli sp. have been used to reduce the incidence of NEC in clinical trials . Lactobacillus sporogenes has not been used in the prevention of NEC in very low-birth weight infants yet . The objective of this study was to evaluate the efficacy of orally administered L sporogenes in reducing the incidence and severity of NEC in very low-birth weight ( VLBW ) infants . Subjects/ Methods : A prospect i ve , blinded , r and omized controlled trial was conducted in preterm infants with a gestational age of <33 weeks or birth weight of < 1500 g. VLBW infants who survived to start enteral feeding were r and omized into two groups The infants in the study group were given L. sporogenes with a dose of 350 000 000 c.f.u . added to breast milk or formula , once a day , starting with the first feed until discharged . The infants in the control group were fed without L. sporogenes supplementation . The primary outcome measurement was death or NEC ( Bell 's stage ⩾2 ) . Results : A total of 221 infants were studied : 110 in the study group and 111 in the control group . There was no significant difference in the incidence of death or NEC between the groups . Feeding intolerance was significantly lower in the probiotics group than in the control group ( 44.5 % ( n : 49 ) vs 63.1 % ( n : 70 ) , respectively ; P=0.006 ) . Conclusions : L. sporogenes supplementation at the dose of 350 000 000 c.f.u/day is not effective in reducing the incidence of death or NEC in VLBW infants , however , it could improve the feeding tolerance OBJECTIVE To test the efficacy of probiotic and prebiotic , alone or combined ( synbiotic ) , on the prevention of necrotizing enterocolitis ( NEC ) in very low birth weight ( VLBW ) infants . STUDY DESIGN A prospect i ve , r and omized , controlled trial was conducted at 5 neonatal intensive care units in Turkey . VLBW infants ( n = 400 ) were assigned to a control group and 3 study groups that were given probiotic ( Bifidobacterium lactis ) , prebiotic ( inulin ) , or synbiotic ( Bifidobacterium lactis plus inulin ) added to breastmilk or formula for a maximum of 8 weeks before discharge or death . The primary outcome was NEC ( Bell stage ≥2 ) . RESULTS The rate of NEC was lower in probiotic ( 2.0 % ) and synbiotic ( 4.0 % ) groups compared with prebiotic ( 12.0 % ) and placebo ( 18.0 % ) groups ( P < .001 ) . The times to reach full enteral feeding were faster ( P < .001 ) , the rates of clinical nosocomial sepsis were lower ( P = .004 ) , stays in the neonatal intensive care unit were shorter , ( P = .002 ) , and mortality rates were lower ( P = .003 ) for infants receiving probiotics , prebiotics , or synbiotic than controls . The use of antenatal steroid ( OR 0.5 , 95 % CI 0.3 - 0.9 ) and postnatal probiotic ( alone or in synbiotic ) ( OR 0.5 , 95 % CI 0.2 - 0.8 ) decreased the risk of NEC , and maternal antibiotic exposure increased this risk ( OR 1.9 , 95 % CI 1.1 - 3.6 ) . CONCLUSIONS In VLBW infants  , probiotic ( Bifidobacterium lactis ) and synbiotic ( Bifidobacterium lactis plus inulin ) but not prebiotic ( inulin ) alone decrease NEC Abstract Objective : The aim of the study was to evaluate the neurodevelopment outcomes of very low birth weight ( VLBW ) preterm infants supplemented with oral probiotics for the prevention of necrotizing enterocolitis ( NEC ) . Methods : A prospect i ve follow-up study was performed in a cohort of VLBW preterm infants enrolled in a single center r and omized controlled clinical trial to evaluate the efficacy of oral probiotics for the prevention of NEC . Cognitive and neuromotor developments were assessed by using the Bayley scales of infant development II . Sensory and neurological performance was evaluated by st and ard techniques . The primary outcome was neurodevelopmental impairment at 18–24 months ’ corrected age . Results : A total of 400 infants completed the trial protocol . Of the 370 infants eligible for follow-up , 249 infants ( 124 in the probiotics group and 125 in the control group ) were evaluated . There was no significant difference in any of the neurodevelopmental and sensory outcomes between the two groups . Conclusion : Oral probiotic given to VLBW infants to reduce the incidense and severity of NEC started with the first feed did not affect neuromotor , neurosensory and cognitive outcomes at 18–24 months ’ corrected age OBJECTIVE To test the hypothesis that normalizing the intestinal flora by administration of prophylactic probiotics would provide a natural defense , thereby reducing both the incidence and severity of  necrotizing enterocolitis ( NEC ) in preterm neonates . STUDY DESIGN Neonates < or = 1500 g birth weight were r and omized to either receive a daily feeding supplementation with a probiotic mixture ( Bifidobacteria infantis , Streptococcus thermophilus , and Bifidobacteria bifidus ; Solgar , Israel ) of 10(9 ) colony forming units (CFU)/day or to not receive feed supplements .  NEC was grade d according to Bell 's criteria . RESULTS For 72 study and 73 control infants , respectively , birth weight ( 1152 + /- 262 g vs 1111 + /- 278 g ) , gestational age ( 30 + /- 3 weeks vs 29 + /- 4 weeks ) , and time to reach full feeds  ( 14.6 + /- 8.7 days vs 17.5 + /- 13.6 days ) were not different . The incidence of NEC was reduced in the study group ( 4 % vs 16.4 % ; P=.03 ) . NEC was less severe in the probiotic-supplemented infants ( Bell 's criteria 2.3 + /- 0.5 vs 1.3 + /- 0.5 ; P=.005 ) . Three of 15 babies who developed NEC died , and all NEC-related deaths occurred in control infants . CONCLUSION Probiotic supplementation reduced both the incidence and severity of NEC in our premature neonatal population BACKGROUND Although recent reports suggest that supplementation with probiotics may enhance intestinal function in premature infants , the mechanisms are unclear , and questions remain regarding the safety and efficacy of probiotics in extremely low-birth-weight infants . OBJECTIVE The objective was to evaluate the efficacy of probiotics on the digestive tolerance to enteral feeding in preterm infants born with a very low or extremely low birth weight . DESIGN In a bicentric , double-blind , r and omized controlled clinical trial that was stratified for center and birth weight , 45 infants received enteral probiotics ( Bifidobacterium longum BB536 and Lactobacillus rhamnosus GG ; BB536-LGG )  and 49 received placebo .  The primary endpoint was the percentage of infants receiving > 50 % of their nutritional needs via enteral feeding on the 14th day of life . A triangular test was used to perform sequential analysis . RESULTS The trial was discontinued after the fourth sequential analysis concluded a lack of effect . The primary endpoint was not significantly different between the probiotic ( 57.8 % ) and placebo ( 57.1 % ) groups ( P = 0.95 ) . However , in infants who weighed > 1000 g , probiotic supplementation was associated with a shortening in the time to reach full enteral feeding ( P = 0.04 ) . Other than colonization by the probiotic strains , no alteration in the composition of intestinal microbiota or changes in the fecal excretion of calprotectin was observed . No colonization by probiotic strains was detected in infants who weighed < or = 1000 g , presumably because of more frequent suspensions of enteral feeding , more courses of antibiotic treatment , or both . CONCLUSIONS Supplementation with BB536-LGG may not improve the gastrointestinal tolerance to enteral feeding in very-low-birth-weight infants but may improve gastrointestinal tolerance in infants weighing > 1000 g. This trial was registered at clinical trials.gov as NCT 00290576 AIM To investigate the colonisation withBifidobacterium breve of the bowels of very low birthweight ( VLBW ) infants . METHODS The adverse effects of B breve were examined in 66 VLBW infants ( preliminary study ) . A prospect i ve r and omised clinical study of 91 VLBW infants was also completed and these infants were followed up for three years . Precise viable bacterial counts of serial stool specimens were examined for the first eight weeks after birth in 10 infants . The colonisation rates of administered bacteria were examined using immunohistochemical staining of stool specimens with a B breve specific monoclonal antibody . RESULTS In the preliminary study there were no side effects attributable to the bacteria . Immunohistochemical staining of stool specimens showed that the colonisation rates of the administered bacteria were 73 % at 2 weeks of age , but only 12 % in the control group . Early administration of B brevesignificantly decreased aspirated air volume from the stomach and improved weight gain . CONCLUSIONS B breve can colonise the immature bowel very effectively and is associated with fewer abnormal abdominal signs and better weight gain in VLBW infants , probably as a result of stabilisation of their intestinal flora and accelerated feeding schedules IMPORTANCE NEC is a common and severe complication in premature neonates , particularly those with very-low-birth-weight ( VLBW , < 1500 g at birth ) .  Probiotics including lactobacillus rhamnosus GG ( LGG ) proved effective in preventing NEC in preterm infants in several RCTs . OBJECTIVE Lactoferrin , a mammalian milk glycoprotein involved in innate immune host defences , can reduce the incidence of NEC in animal models , and its action is enhanced by LGG . We tried to assess whether bovine lactoferrin ( BLF ) , alone or with the probiotic LGG , has a similar effect in human infants , something that has not yet been studied . DESIGN An international , multicenter , r and omized , double-blind , placebo-controlled trial conducted from October 1st , 2007 through July 31st , 2010 . SETTING Thirteen Italian and New Zeal and tertiary neonatal intensive care units . PARTICIPANTS 743 VLBW neonates were assessed until discharge for development of NEC . INTERVENTION Infants were r and omly assigned to receive orally either BLF ( 100 mg/day ) alone ( group LF ; n = 247 ) or with LGG ( at 6 × 10(9 ) CFU/day ; group BLF + LGG ; n = 238 ) , or placebo ( Control group ; n = 258 ) from birth until day 30 of life ( 45 for neonates < 1000 g at birth ) . MAIN OUTCOME MEASURES ≥ stage 2 NEC ; death- and /or-≥ stage 2 NEC prior to discharge . RESULTS Demographics , clinical and management characteristics of the 3 groups were similar , including type of feeding and maternal milk intakes . NEC incidence was significantly lower in groups BLF and BLF + LGG [ 5/247 ( 2.0 % ) ] and 0/238 ( 0 % ) , respectively ] than in controls [ 14/258 ( 5.4 % ) ] ( RR = 0.37 ; 95 % CI : 0.136 - 1.005 ; p = 0.055 for BLF vs. control ; RR = 0.00 ; p < 0.001 for BLF + LGG vs. control ) . The incidence of death- and /or-NEC was significantly lower in both treatment groups ( 4.0 % and 3.8 % in BLF and BLF + LGG vs. 10.1 % in control ; RR = 0.39 ; 95 % CI : 0.19 - 0.80 ; p = 0.008 . RR = 0.37 ; 95 % CI : 0.18 - 0.77 ; p = 0.006 , respectively ) . No adverse effects or intolerances to treatment occurred . CONCLUSIONS AND RELEVANCE Compared with placebo , BLF supplementation alone or in combination with LGG reduced the incidence of ≥ stage 2 NEC and of death- and /or ≥ stage 2 NEC in VLBW neonates . BLF might be a promising strategy to prevent NEC in NICU setting s. Further data on larger sample sizes are warranted before BLF can be widespreadly used in clinical setting s. TRIAL REGISTRATION IS RCT N53107700-http://www.controlled-_trials.com/IS RCT N53107700 OBJECTIVE To assess the effect of probiotics on the incidence of necrotizing enterocolitis ( NEC ) in premature infants born to human immunodeficiency virus (HIV)-positive and HIV-negative women . PATIENTS AND METHODS HIV-exposed and HIV-unexposed premature infants were r and omized to either the probiotic or the placebo group . The probiotic consisted of 1 × 10(9 ) colony-forming units , Lactobacillus rhamnosus GG and Bifidobacterium infantis per day . RESULTS In total , 74 HIV-exposed and 110 HIV-unexposed infants were enrolled and r and omized . The incidence of death [ 4 ( 5.4 % ) vs. 7 ( 6 % ) ; p = 0.79 ] and NEC [ 4 ( 5 % ) vs. 5 ( 5 % ) ; p = 0.76 ] did not differ significantly between the HIV-exposed and HIV-unexposed groups . A significant difference was found for total NEC incidence between the study and control groups [ 3 ( 3 % ) vs. 6 ( 6 % ) ; p = 0.029 ] . The incidence of NEC in the HIV-exposed group differed significantly [ Bells I 2 ( 5 % ) vs. Bells III 2 ( 5 % ) ; p = 0.045 ) . CONCLUSION Probiotic supplementation reduced the incidence of NEC in the premature very low birth weight infants ; however , results failed to show a lower incidence of NEC in HIV-exposed premature infants . A reduction in the severity of disease was found in the HIV-exposed study group Objective : To compare the effect of 2 prebiotic/probiotic products on weight gain , stool microbiota , and stool short-chain fatty acid ( SCFA ) content of premature infants . Patients and Methods : This r and omized , blinded , placebo-controlled trial included 90 premature infants treated with either a dietary supplement containing 2 lactobacillus species plus fructooligosaccharides ( CUL , Culturelle , ConAgra , Omaha , NE ) , a supplement containing several species of lactobacilli and bifidobacteria plus fructooligosaccharides ( PBP  , ProBioPlus DDS , UAS Laboratories , Eden Prairie , MN ) , or placebo ( a dilute preparation of Pregestamil formula ) twice daily for 28 days or until discharge if earlier . The primary outcome was weight gain . Secondary outcomes were stool bacterial analysis by culture and 16S rDNA quantitative polymerase chain reaction and stool SCFA content measured by high performance liquid chromatography . Results : Both prebiotic/probiotic combinations contained more bacterial species than noted on the label . No significant effect on infant growth of either prebiotic/probiotic supplement was observed . By cultures , 64 % of infants receiving PBP became colonized with bifidobacteria , compared with 18 % of infants receiving CUL and 27 % of infants receiving placebo ( chi-square , P = 0.064 ) . No differences were noted between groups in colonization rates for lactobacilli , Gram-negative enteric bacteria , or staphylococci . By 16S rDNA polymerase chain reaction analysis , the bifidobacteria content in the stools of the infants receiving PBP was higher than in the infants receiving CUL or placebo ( Kruskal-Wallis , P = 0.011 ) . No significant differences in stool SCFA content were detected between groups . No adverse reactions were noted . Conclusions : Infants receiving PBP were more likely to become colonized with bifidobacteria . No significant differences in weight gain or stool SCFA content were detected OBJECTIVE To compare stool colonization among premature infants receiving high-dose probiotics versus st and ard dose . STUDY DESIGN This blinded , r and omized , placebo-controlled trial was conducted in a Level III neonatal unit . Eligibility criteria were gestational age 27 - 33 weeks , age < 96 hours , tolerating milk ≥ 15 mL/kg/day and availability for follow-up . Gastro-intestinal/life-threatening malformations and necrotizing enterocolitis/sepsis were exclusions . A total of 149 subjects were r and omly allocated to groups A through D ( received 12-hourly probiotic supplements of 10(10 ) cells for 21 days , 10(10 ) cells for 14 days , 10(9 ) cells for 21 days and placebo , respectively ) . Key outcome was stool colonization by a probiotic organism at 28 days . RESULTS Colonization with Lactobacillus and Bifidobacterium was significantly higher in groups A , B , and C versus placebo respectively , but groups A through C did not differ from each other . There were trends toward more colony forming unit ( cfu ) of Lactobacillus and Bifidobacterium per milliliter of stool in group A versus B and B versus C. Groups A and B and spontaneous preterm labor ( SPL ) independently predicted high Lactobacillus counts on day 28 ; groups A , B , and C and SPL predicted high Bifidobacterium counts . CONCLUSION Proportion of infants colonized with probiotic species was similar with high-dose and st and ard dose regimes
target: LIMITATIONS Heterogeneity of organisms and dosing regimens studied prevent a species-specific treatment recommendation from being made .
  CONCLUSIONS Preterm infants benefit from probiotics to prevent severe NEC and death
background: CONTEXT Necrotizing enterocolitis ( NEC ) is the most frequent gastrointestinal emergency in neonates .
  The microbiome of the preterm gut may regulate the integrity of the intestinal mucosa .
  Probiotics may positively contribute to mucosal integrity , potentially reducing the risk of NEC in neonates .
  OBJECTIVE To perform an up date d systematic review and meta- analysis on the efficacy and safety of probiotics for the prevention of NEC in premature infants .
