Severe and widespread atopic eczema often fails to respond adequately to currently available therapies. Following the observation of substantial benefit in patients receiving oral treatment with daily decoctions of traditional Chinese medicinal plants, we undertook a placebo-controlled double-blind trial of a specific prescription formulated for widespread non-exudative atopic eczema. Forty-seven children were given active treatment and placebo in random order, each for 8 weeks, with an intervening 4-week wash-out period. Thirty-seven children tolerated the treatment and completed the study. Response to active treatment was superior to response to placebo, and was clinically valuable. There was no evidence of haematological, renal or hepatic toxicity. These findings anticipate a wider therapeutic potential for traditional Chinese medicinal plants in this disease, and other skin diseases. Probiotic bacteria are suggested to reduce symptoms of the atopic eczema/dermatitis syndrome (AEDS) in food-allergic infants. We aimed to investigate whether probiotic bacteria have any beneficial effect on AEDS.
                Follow-up of severity of AEDS by the Severity Scoring of Atopic Dermatitis (SCORAD) index in 230 infants with suspected cow's milk allergy (CMA) receiving, in a randomized double-blinded manner, concomitant with elimination diet and skin treatment, Lactobacillus GG (LGG), a mixture of four probiotic strains, or placebo for 4 weeks. Four weeks after the treatment, CMA was diagnosed with a double-blind placebo-controlled (DBPC) milk challenge in 120 infants.
                In the whole group, mean SCORAD (at baseline 32.5) decreased by 65%, but with no differences between treatment groups immediately or 4 weeks after the treatment. No treatment differences were observed in infants with CMA either. In IgE-sensitized infants, however, the LGG group showed a greater reduction in SCORAD than did the placebo group, -26.1 vs-19.8 (P=0.036), from baseline to 4 weeks after the treatment. Exclusion of infants who had received antibiotics during the study reinforced the findings in the IgE-sensitized subgroup.
                Treatment with LGG may alleviate AEDS symptoms in IgE-sensitized infants but not in non-IgE-sensitized infants. Although colonization of atopic dermatitis by Staphylococcus aureus is universal and bacterial infection is common, it is not known whether antibiotic therapy is helpful in eczematous children who do not have any signs suggestive of bacterial infection. Fifty children aged 1-16 years with atopic dermatitis took part in a randomized double-blind placebo-controlled study of 4 weeks treatment with oral flucloxacillin, with an 8-week follow-up period. The change in the mean of the log10 of the counts/cm2 of S. aureus after 4 weeks of treatment was significantly different for patients receiving treatment, compared with the change for those receiving the placebo (P = 0.008). However, the difference in the change at 14 days after stopping treatment was not significant (P = 0.32). Methicillin-resistant strains of S. aureus were cultured from five children during or after treatment. Flucloxacillin did not improve the symptoms or clinical appearance of atopic dermatitis and only temporarily changed skin colonization by S. aureus. Reversal of the progressive increase in frequency of atopic disease would be an important breakthrough for health care and wellbeing in western societies. In the hygiene hypothesis this increase is attributed to reduced microbial exposure in early life. Probiotics are cultures of potentially beneficial bacteria of the healthy gut microflora. We assessed the effect on atopic disease of Lactobacillus GG (which is safe at an early age and effective in treatment of allergic inflammation and food allergy).
                In a double-blind, randomised placebo-controlled trial we gave Lactobacillus GG prenatally to mothers who had at least one first-degree relative (or partner) with atopic eczema, allergic rhinitis, or asthma, and postnatally for 6 months to their infants. Chronic recurring atopic eczema, which is the main sign of atopic disease in the first years of life, was the primary endpoint.
                Atopic eczema was diagnosed in 46 of 132 (35%) children aged 2 years. Asthma was diagnosed in six of these children and allergic rhinitis in one. The frequency of atopic eczema in the probiotic group was half that of the placebo group (15/64 [23%] vs 31/68 [46%]; relative risk 0.51 [95% CI 0.32-0.84]). The number needed to treat was 4.5 (95% CI 2.6-15.6).
                Lactobacillus GG was effective in prevention of early atopic disease in children at high risk. Thus, gut microflora might be a hitherto unexplored source of natural immunomodulators and probiotics, for prevention of atopic disease. Although gamma-linolenic acid (GLA) has been shown to correct deficiencies in skin lipids associated with reduced delta-6-desaturase activity which should result in improvement of dysregulation of inflammation and immunity in atopic eczema, clinical studies with evening primrose oil containing 10% GLA have yielded contradictory results. We have therefore examined the effect of a higher percentage (at least 23%) GLA-containing borage oil in adults with stable atopic eczema of moderate severity in a double-blind, multicentre study. One hundred and sixty patients were randomized to take daily either 500 mg of borage oil-containing capsules or the bland lipid miglyol as a placebo over a 24-week period. Use of topical diflucortolone-21-valerate cream was allowed as rescue medication, with the amount used until response being defined as primary, and clinical improvement as secondary efficacy criteria. Although several clinical symptoms improved compared with placebo, the overall response to borage oil did not reach statistical significance. Significant differences in favour of borage oil were, however, observed in a subgroup excluding patients who failed to show increased erythrocyte dihomo-gamma-linolenic acid levels and in whom adherence to inclusion criteria and the study protocol were questionable. GLA metabolites increased in borage oil-treated patients only, and serum IgE showed a trend to decrease on overall and subgroup analysis. No substance-related adverse effects were observed. This study shows no overall efficacy of GLA-containing borage oil in atopic eczema, with steroid use being the primary response parameter, although it suggests that a subgroup of patients may benefit from this well-tolerated treatment. Psychological problems in children and parents related to children's atopic eczema (AE) may impede the success of treatment. We studied the question, if behavior-based parental education in groups (DPE) or standardized video-education (VPE) could enhance dermatological treatment effects and reduce skin-damaging behaviors in children and stress in their mothers.
                47 mothers attending the university outpatient-clinic for dermatology and their AE-children (mean age 4 years) participated in the study. 18 mothers underwent the DPE (10 sessions), 15 mothers worked with VPE at home. Dermatological standard treatment (CG; N = 14) served as control for a 16-weeks-evaluation-period.
                AE-symptoms improved overall, but the effectiveness of the treatments differed significantly, improval with parent education and was best with VPE. Psychological problems of mothers were equally reduced with DPE and VPE.
                It is suggested that VPE is a cost effective and less time consuming method for supporting dermatological therapy of AE in children. Staphylococcus aureus has a peculiar ability to colonize the skin of patients with eczema and atopic dermatitis (AD), and is consistently found in eczematous skin lesions in these patients. A correlation between the severity of the eczema and colonization with S. aureus has been demonstrated, and it has been determined that bacterial colonization is an important factor aggravating skin lesions. Patients colonized with S. aureus have been treated with antibiotics in several open and double-blind placebo-controlled studies, with conflicting results.
                To investigate the colonizing features of S. aureus in the lesional and nonlesional skin of patients with eczema and AD in China and to compare the therapeutic effect of mupirocin plus hydrocortisone butyrate with vehicle ointment plus hydrocortisone butyrate.
                A multicentre, double-blind randomized trial was conducted. Eczema Area and Severity Index (EASI) scores were evaluated before the start of the trial and on the 7th, 14th and 28th day of treatment. Swabs for bacterial isolation were taken from lesional skin before the start of the trial and on the 7th, 14th and 28th day of treatment, and from nonlesional skin only before the start of the trial. A combination topical therapy with mupirocin plus hydrocortisone butyrate ointment was used in the experimental group, with vehicle ointment plus hydrocortisone butyrate ointment as a control.
                Of 327 patients enrolled in the study, 208 had eczema and 119 had AD. Bacteria were isolated from 70.2% of lesional and 32.7% of nonlesional skin samples from patients with eczema, of which S. aureus accounted for 47.3% and 27.9%, respectively. Bacteria were isolated from 74.8% of lesional and 34.5% of nonlesional skin samples from patients with AD, of which S. aureus accounted for 79.8% and 80.5%, respectively. The colonization density of S. aureus was markedly higher in lesional than in nonlesional skin, both in patients with eczema and with AD (P < 0.01, P < 0.05), and was positively correlated with lesion severity. Considering the EASI scores before and after treatment and the final effective rate, good therapeutic effects were obtained in both the combination experimental groups and the control groups (P < 0.01), and there were no differences in the global therapeutic effect between the two groups in patients with eczema and with AD (P > 0.05). However, in patients with eczema with a clinical score of > 8 or in patients with AD with a clinical score of > 7, the therapeutic effect in the experimental groups was superior to that in the control groups (P < 0.05) on the 7th day of treatment. There were no differences between the two groups on the 14th and 28th days of treatment (P > 0.05). Following the improvement of symptoms and signs of eczema and AD, the positive rates of bacteria and S. aureus were reduced on the 7th day of treatment.
                This study confirmed that lesional skin of patients with eczema and AD was more frequently colonized with S. aureus than was nonlesional skin. The more severe the eczema, the higher the colonization rate of S. aureus, and S. aureus was also more often present in lesional and nonlesional skin in patients with AD than in those with eczema. Staphylococcus aureus infection is related to the pathogenesis of eczema and AD. An antibiotic-corticosteroid combination and corticosteroid alone both gave good therapeutic effect in eczema and in AD, and both reduced colonization by S. aureus. Early combined topical therapy is beneficial to patients with moderate to severe eczema and AD, and it is unnecessary to use antibiotics at later stages of disease or in mild eczema or AD. Some studies have suggested that supplementation of food with lactobacilli may prevent or improve atopic dermatitis in children. This study was designed to investigate the therapeutic effect of Lactobacillus rhamnosus GG (LGG) as a food supplement in infants suffering from atopic dermatitis.
                Infants aged 3-12 months suffering from mild-to-moderate atopic dermatitis (severity scoring of atopic dermatitis or SCORAD index of 15-40) without current antiinflammatory treatment were randomized to receive LGG (5 x 10(9) colony forming units b.i.d.) or placebo as a food supplement for 12 weeks. Severity scoring of atopic dermatitis index and use of hydrocortisone 1% ointment as rescue medication (2 points per application) were recorded at 4, 8, and 12 weeks of treatment and combined as symptom load (SL).
                Fifty-four infants (LGG group, mean +/- SD SCORAD index 24.6 +/- 8.8) and 48 infants (placebo group, SCORAD index 23.6 +/- 7.8) were randomized and completed the treatment period (intention-to-treat analysis). Symptom load generally improved over time at 4 weeks (LGG vs placebo, 23.8 +/- 12.4 vs 20.6 +/- 9.9), 8 weeks (22.5 +/- 14.6 vs 17.9 +/- 13.1), and 12 weeks (19.6 +/- 15.4 vs 15.1 +/- 12.1), without statistically significant group differences. When stratified for age, eczema severity or use of rescue medication, no statistically significant group differences, in improvement, were found. No significant group differences were found for the use of rescue medication (0.8 +/- 45.0 g vs 3.5 +/- 29.8 g), increase in mean logarithmic total serum IgE (0.17 +/- 0.30 kU/l vs 0.26 +/- 0.45 kU/l), and newly developed allergic sensitization against hen's egg or cow's milk (18.8%vs 10.0%).
                This placebo-controlled trial showed no therapeutic effect of LGG against mild-to-moderate atopic dermatitis in infancy. This double-blind study determined whether daily bathing with an antibacterial soap would reduce the number of Staphylococcus aureus on the skin and result in clinical improvement of atopic dermatitis. For 9 weeks, 50 patients with moderately severe atopic dermatitis bathed daily with either an antimicrobial soap containing 1.5% triclocarban or the placebo soap. They also used a nonmedicated moisturizer and 0.025% triamcinolone acetonide cream as needed, but the availability of the corticosteroid cream was discontinued after 6 weeks. The antimicrobial soap regimen caused significantly greater improvement in the severity and extent of skin lesions than the placebo soap regimen, which correlated with reductions both in S aureus in patients with positive cultures at baseline and in total aerobic organisms. Outcome measures included reductions in S aureus, total aerobic organisms, and dermatologic assessments. Overall, daily bathing with an antibacterial soap was well tolerated, provided clinical improvement, and reduced levels of skin microorganisms. Atopic eczema begins primarily in infancy or early childhood, and sleep loss due to night-time pruritus can have a considerable impact on patients' and parents' quality of life (QoL). In this study, infants (n = 196) with mild to severe atopic eczema were randomized 2:1, double-blind, to receive either pimecrolimus cream 1% (Elidel, Novartis Pharma, Nürnberg, Germany) or the corresponding vehicle bid for 4 wk, followed by a 12 wk, open-label phase and a 4 wk, treatment-free, follow-up period. The parents' QoL was measured at baseline and at the end of the double-blind phase, using the questionnaire 'QoL in Parents of Children with Atopic Dermatitis' (PQoL-AD), thus data presented here refer to the initial 4-wk treatment phase only. After 4 wk of double-blind treatment, an increase in the mean percentage change from baseline in eczema area and severity index of 71.5% was observed with pimecrolimus, compared with 19.4% with vehicle. The increase in efficacy was paralleled by the following mean percentage changes from baseline in the five domains of the questionnaire in pimecrolimus and vehicle, respectively: psychosomatic well-being: 14.6% vs. 6.2%; effects on social life: 6.7% vs. 2.3%; confidence in medical treatment: 10.0% vs. 3.7%; emotional coping: 16.1% vs. 6.5%; acceptance of disease: 19.6% vs. 7.0%. Analysis (ancova) of the dependent variable difference from baseline and the covariate baseline value revealed values of p < 0.05 for all five domains, despite the very short duration of the study. It is concluded that improvements in atopic eczema in infants achieved by treatment with pimecrolimus have a significant beneficial effect on the QoL of parents. Studies have been performed suggesting that administration of probiotics may have therapeutic and/or preventive benefits in the development of sensitization and atopic disease, particularly in infants with atopic dermatitis (AD).
                The purpose of this study was to evaluate the clinical and immunological effects of supplementation of a hydrolysed formula with two probiotic strains of bacteria on symptoms of AD in infancy.
                We conducted a randomized, double-blind, placebo-controlled study. After 4-6 weeks of baseline and double-blind, placebo-controlled challenges for diagnosis of cow's milk allergy (CMA), infants less than 5 months old with AD received a hydrolysed whey-based formula as placebo (n = 17), or supplemented with either Lactobacillus rhamnosus (n = 17) or Lactobacillus GG (n = 16) for 3 months. Before, during and after intervention, the clinical severity of AD was evaluated using SCORing index Atopic Dermatitis (SCORAD). Allergic sensitization was evaluated by measurement of total IgE and a panel of food-specific IgEs as well as skin prick testing for cow's milk. Inflammatory parameters were blood eosinophils, eosinophil protein X in urine, fecal alpha-1-antitrypsin and production of IL-4, IL-5 and IFN-gamma by peripheral blood mononuclear cells after polyclonal stimulation.
                No statistically significant effects of probiotic supplementation on SCORAD, sensitization, inflammatory parameters or cytokine production between groups were found. Only four infants were diagnosed with CMA.
                We found no clinical or immunological effect of the probiotic bacteria used in infants with AD. Our results indicate that oral supplementation with these probiotic bacterial strains will not have a significant impact on the symptoms of infantile AD. The safety and efficacy of a 1% cream formulation of pimecrolimus, a selective, nonsteroid immunomodulator, was studied in infants with atopic dermatitis (AD).
                During a 6-week double-blind phase, 186 infants with mild/moderate AD were randomly assigned to twice-daily pimecrolimus cream 1% or vehicle. All patients were subsequently treated with open-label pimecrolimus for 20 weeks.
                At the end of the double-blind phase, 54.5% and 23.8% of patients in the pimecrolimus and vehicle groups, respectively, were clear or almost clear of AD (P <.001). Similar improvements were observed in the Eczema Area and Severity Index, pruritus assessment, and the care giver's assessment. By the first return visit, 69.9% and 36.5% of pimecrolimus and vehicle-treated patients, respectively, achieved absent or mild pruritus. Efficacy during the double-blind phase was maintained throughout the open-label phase. Vehicle-treated patients transferring to open-label pimecrolimus rapidly achieved disease control comparable to those receiving continuous pimecrolimus. There were no significant differences between groups in application site reactions or skin infections. Most adverse events were mild or moderate and unrelated to treatment.
                Pimecrolimus was safe in infants with AD, with rapid and sustained efficacy. Pimecrolimus holds promise as a valuable new treatment option for the youngest patients with AD. Pimecrolimus cream 1% (Elidel, SDZ ASM 981), a nonsteroid selective inhibitor of inflammatory cytokines, is effective in the treatment of atopic dermatitis (AD). In this study we compared early intervention with pimecrolimus cream with treatment with a vehicle control.
                The purpose of this investigation was to assess whether early treatment in infants of AD signs/symptoms with pimecrolimus could influence long-term outcome by preventing disease flares.
                In this 1-year, double-blind controlled study, 251 infants aged 3 to 23 months with AD were randomized 4:1 to a pimecrolimus-based regimen (n = 204) or a conventional treatment regimen (n = 47). Both groups used emollients for dry skin. Early AD signs and symptoms were treated either with pimecrolimus cream to prevent flares or, in the control group, with vehicle. Vehicle was used to maintain blinding conditions. In the event of flares, moderately potent corticosteroid was permitted in both groups. The primary efficacy end point was the incidence of flares at 6 months.
                Pimecrolimus significantly reduced the incidence of flares compared with control treatment (P <.001), with 67.6% versus 30.4% of patients completing 6 months with no flare and 56.9% versus 28.3% completing 12 months with no flare. Overall corticosteroid use was substantially lower in the pimecrolimus group: 63.7% versus 34.8% of patients did not use corticosteroids at all during the study. Pimecrolimus was also more effective than control treatment in the long-term control of pruritus and the signs of AD. There were no clinically significant differences in incidence of adverse events between the 2 treatment groups.
                Treatment with pimecrolimus of early signs and symptoms significantly modified the disease course in infants by reducing the incidence of flares and improving overall control of AD. Pimecrolimus was safe and well tolerated. To analyse how web-based consultations for parents of children with atopic dermatitis affect self-management behaviour, health outcome, health resource use and family costs.
                Ninety-eight children with atopic dermatitis were randomly assigned to intervention and control groups. The intervention group received remote dermatology consultations through a secure web-based communication system. The control group was encouraged to seek treatment through traditional means such as general practitioner visits and hospital care. Both groups received an extensive individual educational session prior to the intervention.
                Thirty-eight percent of the intervention group used web-based consultations 158 times ranging from 1 to 38 consultations per patient. We found no change in self-management behaviour, health outcome or costs. The intervention group tended to have fewer visits to practitioners offering complementary therapies than the control group, and we found a positive correlation between emergency visits at baseline and messages sent. Both groups, however, reduced the mean number of skin care treatments performed per week and had fewer total health care visits after the intervention.
                We found no effect of supplementing traditional treatment for childhood dermatitis with web-based consultations. This study showed that web consultations is feasible, but more research is needed to determine its effect on self-management skills, health outcome and resource use.
We failed to find clear evidence of benefit for antimicrobial interventions for people with atopic eczema, despite their widespread use. This does not necessarily mean they do not work because the studies were small and poorly reported. Further large studies with long-term outcomes and clearly defined participants are urgently required.
