The objective of this study was to compare the efficacy of corticotropin (ACTH) versus vigabatrin in treating infantile spasms and to determine which medication has a more favorable long-term outcome in terms of cognitive function, evolution of epilepsy, and incidence of autism. Patients with infantile spasms were included in the study if they were 3 to 16 months old, had hypsarrhythmia, and had no previous treatment with vigabatrin or corticosteroids. Patient evaluation included electroencephalographic and psychometric measures before and after treatment. Patients were stratified based on etiology (idiopathic or symptomatic) and sex and then randomized between the ACTH and vigabatrin treatment groups. Each of the treatment groups received either ACTH or vigabatrin for 2 weeks. At the end of 2 weeks of treatment, patients were considered responders if spasms and hypsarrhythmia resolved. Nonresponders were crossed over and treated with the alternate drug. Nine patients were included in the study. Three patients received ACTH, one of whom was a responder. Six patients received vigabatrin, three of whom were responders. The five nonresponders received both therapies. All patients had some degree of developmental plateau or regression before the initiation of treatment. Four patients with idiopathic infantile spasms showed improved cognitive function following treatment. The remaining five patients remained significantly delayed. Five patients with symptomatic infantile spasms had epilepsy following treatment; three of them were in the autistic spectrum. The small number of infants in this pilot study is insufficient to determine which of the two drugs is more effective. However, the following trends were identified: vigabatrin may be more effective for patients with symptomatic infantile spasms; patients with idiopathic infantile spasms tend to have a better cognitive outcome; and patients with symptomatic infantile spasms tend to develop both epilepsy and autism. Infantile spasms is the name given to a difficult to treat, severe infantile epilepsy with high morbidity. The United Kingdom Infantile Spasms Study (UKISS) showed that absence of spasms on days 13 and 14 after randomisation was more common in infants allocated hormonal treatments than vigabatrin. At 12-14 months, those with no identified aetiology allocated hormonal treatment had better development. However, epilepsy outcome was not affected by treatment allocated. It is not known if the difference in development persists as the infants grow.
                Infants in UKISS were followed up blind to treatment allocation by telephone at a mean age of 4 years using the Vineland Adaptive Behaviour Scales (VABS) and an epilepsy questionnaire.
                9 of 107 enrolled infants had died. 77 were traced and consented to take part. The median (quartile) VABS scores were 60 (42, 97) for the 39 allocated hormonal treatment and 50 (36, 67) for the 38 allocated vigabatrin (Mann-Whitney U=575; p=0.091; median difference (95% CI): 8 (-1 to 19)). For those with no identified aetiology, VABS scores were 96 (52, 102) for the 21 allocated hormonal treatment and 63 (37, 92) for the 16 allocated vigabatrin (U=98.5; p=0.033; median difference (95% CI): 14 (1 to 42)).The proportions in each treatment group with epilepsy were similar.
                For all 77 infants, development and epilepsy outcomes were not significantly different between the two treatment groups. The better development seen at 14 months in those with no identified aetiology allocated hormonal treatment was seen again at 4 years in this study. Vigabatrin has been shown to be efficient in infants with infantile spasms and tuberous sclerosis, in open studies. In order to compare vigabatrin to oral steroids, a prospective randomized multicenter study was implemented using both drugs as monotherapy in newly diagnosed patients with infantile spasms and tuberous sclerosis. Eleven infants received vigabatrin (150 mg/kg per day) and 11 hydrocortisone (15 mg/kg per day) for 1 month. Spasm free patients continued vigabatrin or progressively stopped hydrocortisone in 1 month, non-responders were crossed to the other drug for a new 2 month-period. All vigabatrin patients (11/11) were spasm-free versus 5/11 hydrocortisone infants (P < 0.01). Seven patients were crossed to vigabatrin (six for inefficacy, one for adverse events) and became also totally controlled. Mean time to disappearance of infantile spasms was 3.5 days on vigabatrin versus 13 days on hydrocortisone (P < 0.01). Five patients exhibited side effects on vigabatrin but nine on hydrocortisone (P = 0.006). Vigabatrin should therefore be considered as the first choice treatment for infantile spasms due to tuberous sclerosis. Vigabatrin (VGB) has been shown to be an effective drug in the treatment of infantile spasms (West syndrome) in predominantly retrospective and open but also in prospective studies. This prospective, randomised, and placebo-controlled trial of VGB in infantile spasms was considered to be justified and feasible to confirm or refute these previous findings.
                Forty children with newly diagnosed infantile spasms received either VGB or placebo for 5 days in a double blind, placebo-controlled, parallel-group study, after which all the infants continuing in the study were treated openly with VGB for a minimum of 24 weeks.
                Compared with baseline, at the end of the double-blind phase, the patients treated with VGB had a 78% (95% confidence interval, 55-89%) reduction in spasms compared with 26% (-56-65%) in the group treated with placebo (p = 0.020). Seven VGB-treated patients and two placebo-treated patients were spasm free on the final day of the double-blind period (p = 0.063). At the end of the study, 15 children (38% of the original 40 patients or 42% of the 36 patients who entered the open phase) were spasm free with VGB monotherapy. No patient withdrew from the study because of an adverse event.
                This unique randomized, placebo-controlled study is the first to demonstrate the efficacy of a specific drug in the treatment of West syndrome and supports the results of previously published open and prospective trials. It further confirms that VGB could be considered as the drug of first choice in treating infantile spasms. To compare the efficacy of corticotropin (ACTH) (150 U/m2/day) and prednosone (2 mg/kg/day) given for 2 weeks, in suppressing clinical spasms and hypsarrhythmic electroencephalogram (EEG) in infantile spasms (IS). AACTH and prednisone are standard treatments for IS. ACTH at high doses causes severe dose- and duration-dependent side effects, but may be superior to prednisone, based on retrospective or uncontrolled studies. Blinded prospecive studies have shown equal efficacy of prednisone and low-dose ACTH, and low versus high-dose ACTH.
                A prospective, randomized, single-blinded study.
                Patient population consisted of consecutive infants fulfilling entry criteria, including the presence of clinical spasms, hypsarrhythmia (or variants) during a full sleep cycle video-EEG, and no prior steroid/ACTH treatment. Response required both cessation of spasms and elimination of hypsarrhythmia by the end of the 2-week treatment period, as determined by an investigator "blinded" to treatment. Treatment of responders was tapered off over 12 days; those failing one hormone were crossed-over to the other.
                OF 34 eligible infants, 29 were enrolled. Median age of patients was 6 months. Twenty-two infants were "symptomatic" with known or suspected cause, and seven were cryptogenic (two normal). Of 15 infants randomized to ACTH, 13 responded by EEG and clinical criteria (86.6%); Seizures stopped in an additional infant, but EEG remained hypsarrhythmic (considered a failure). Four of the 14 patients given prednisone responded (28.6%,, with complete clinical-EEG correlation), significantly less than with ACTH, (chi2 test).
                Using a prospective, randomized approach, a 2-week course of high-dose ACTH is superior to 2 weeks of prednsone for treatment of IS, as assessed by both clinical and EEG criteria. West syndrome (WS) is still one of the most difficult to treat epilepsies in infancy. Sulthiame (STM), which is commonly used in some countries in the treatment of benign focal epilepsies in childhood, has been suggested to be effective in WS too. This prospective, randomized placebo-controlled study was designed to prove or refute this hypothesis.
                Thirty-seven infants aged between 3.5 and 15 months with newly diagnosed WS received baseline therapy with pyridoxine (PDX). The children were randomized in a double-blind fashion to STM (n = 20) or placebo (n = 17), starting at day 4 at a moderate dose of 5 mg/kg body weight. Without complete cessation of infantile spasms (ISs) and resolution of hypsarrhythmia as the definition criteria of a response, the dose was doubled at day 7. The final examination was undertaken at the end of day 9.
                Based on the intention to treat, six (30%) of 20 patients responded to STM (p < 0.025), as did six (35%) of 17 infants fulfilling the study criteria (p < 0.01). Patients with tuberous sclerosis did not respond to STM (n = 3) No patient responded to placebo. One patient in the verum group was withdrawn because of reversible somnolence.
                As no child in the placebo group responded to the baseline PDX therapy, nor did any child in the STM group during the first 3 days of baseline therapy, PDX does not seem to be effective in WS. STM has a positive effect in the primary therapy of WS, comparable to that of vigabatrin. To study the effect of highdose prednisone on intracranial pressure (ICP), cranial computed tomographic (CT) findings, and clinical outcome in young children with moderate to severe tuberculous meningitis (TBM).
                Prospective, controlled, randomized study.
                Continuous lumbar, cerebrospinal fluid pressure monitoring and contrasted CT scanning were performed in 141 consecutive children with TBM at admission. All children were then randomly allocated to a nonsteroid group (71 children) or a steroid group (70 children) who received prednisone (first 16 children, 2 mg/kg per day; next 54 children, 4 mg/kg per day) for the first month of treatment. ICP monitoring and CT scanning were repeated regularly, and clinical outcome was assessed after 6 months of antituberculosis treatment.
                No statistically significant difference in ICP or the degree of hydrocephalus (as demonstrated by CT scan) was found between the steroid and nonsteroid groups after the first month of treatment. Basal ganglia infarcts developed in 16% of children in the steroid group and 24% in the nonsteroid group during the first month of treatment. Neither this incidence nor the eventual size of infarcts present at admission differed significantly between the two treatment groups. Single or multiple tuberculomas were seen on the first CT scans of 7 children (5%), whereas tuberculomas developed in 11 children (8%) at treatment. Both the response of the tuberculomas to treatment and the incidence of new tuberculomas were significantly improved by steroid therapy. Basal enhancement was also significantly less in the steroid group after 1 month of treatment. Steroids lowered mortality in stage III TBM significantly. Similarly, more surviving children in the steroid group had IQs of greater than 75 than did the those in the nonsteroid group. No significant difference was found in the incidence of motor deficit, blindness, or deafness.
                Corticosteroids significantly improved the survival rate and intellectual outcome of children with TBM. Enhanced resolution of the basal exudate and tuberculomas by steroids was shown by serial CT scanning. Corticosteroids did not affect ICP or the incidence of basal ganglia infarction significantly. A large randomized study was conducted in patients with newly diagnosed infantile spasms to compare 2 doses of vigabatrin in achieving spasm cessation. High (100-148 mg/kg/d) and low (18-36 mg/kg/d) oral doses of vigabatrin were evaluated in a randomized, single-blind study of 14 to 21 days with subsequent open-label treatment up to 3 years. Spasm cessation was defined as 7 consecutive days of spasm freedom beginning within the first 14 days, confirmed by video-electroencephalogram. A total of 221 subjects comprised the modified intent-to-treat cohort. More subjects in the high-dose group achieved spasm cessation compared with the low-dose vigabatrin group (15.9% [17/107] vs 7.0% [8/114]; P = .0375). During follow-up, 39 of 171 (23%) subjects relapsed; 28 of 39 (72%) regained spasm freedom. Adverse events were primarily mild to moderate in severity. Vigabatrin had a dose-dependent effect in spasm reduction. Spasm cessation occurred rapidly and was maintained in the majority of infants. To compare the efficacy and tolerability of vigabatrin (VGB) and adrenocorticotrophic hormone (ACTH) as first-line therapy in infantile spasms.
                Forty-two infants (22 males, 20 females) aged 2-9 months with newly diagnosed infantile spasms, were included in the trial. Patients were randomized to receive VGB 100-150 mg/kg/day or Depot ACTH 10 IU/day. The alternative drug was given if spasms were not controlled within 20 days or in cases of intolerance to initial therapy. Twenty-three patients (7 cryptogenic, 16 symptomatic) received VGB as first-line therapy; 19 patients (8 cryptogenic, 11 symptomatic) received ACTH as the first drug.
                Cessation of spasms was observed in 11 (48%) of the patients randomized to VGB and in 14 (74%) of those randomized to ACTH. Response to VGB was observed within 1-14 days, but two-thirds of patients (7/11) responded within 3 days. In the group treated with VGB, side effects such as drowsiness, hypotonia and irritability were observed in 13% of patients, compared with 37% in the group treated with ACTH. VGB was more effective than ACTH as treatment for cerebral malformations or tuberous sclerosis, whereas ACTH proved more effective in perinatal hypoxic/ischemic injury. The efficacy of the two drugs was similar in cryptogenic cases. Disappearance of interictal EEG abnormalities occurred sooner in patients randomized to ACTH than in those who received VGB as initial therapy. During the second phase, the alternative drug was given to the resistant patients. Spasms ceased in 2 of 5 patients treated with VGB and in 11 of 12 patients treated with ACTH. After 3 months, relapses of spasms were observed in 6 patients treated with ACTH and in 1 treated with VGB. VGB produced a therapeutic response in nearly half the patients receiving this drug.
                Our data lend further support to the view that VGB may be considered a first-choice drug in the treatment of IS. Cognitive impairment is observed commonly in children with a history of infantile spasms (IS). The goal of this study was to prospectively examine the effect on cognitive outcome of a neuroprotective agent used as adjunctive therapy during treatment of the spasms.
                In a randomized controlled trial, patients received a standardized therapy plus flunarizine or placebo. The standardized treatment consisted of vigabatrin as first-line therapy. Nonresponders were switched to intramuscular synthetic adrenocorticotropic hormone (sACTH depot) after 2 weeks and, if necessary, to topiramate after two additional weeks. The Vineland Adaptive Behavior Scale (VABS) and Bayley Scales of Infant Development (BSID) were used as outcome measures 24 months after the intervention.
                Sixty-eight of 101 children diagnosed over 3 years in seven centers in Canada received either adjunctive flunarizine or placebo. Sixty-five of the 68 children (96%) became spasm-free within 8 weeks and no late relapse occurred. Bayley and Vineland results were available at baseline and at 24 months in 45 children. There was no significant difference in the BSID developmental quotient between the flunarizine- and placebo-treated children at baseline (44.3 ± 35.5 vs. 30.9 ± 29.8; p = 0.18) or 24 months later (56.9 ± 33.3 vs. 46 ± 34.2; p = 0.29). However, the 10 flunarizine-treated children with no identified etiology had a better outcome than the eight controls at 24 months on both the Vineland Scale (84.1 ± 11.3 vs. 72.3 ± 9.8; p = 0.03) and the Bayley Scale (87.6 ± 14.7 vs. 69.9 ± 25.3; p = 0.07).
                Our study failed to demonstrate a protective effect of flunarizine on cognitive outcome in a cohort of children with IS. An analysis of subgroups suggested that flunarizine may further improve cognitive outcome in children with no identified etiology.
                Wiley Periodicals, Inc. © 2012 International League Against Epilepsy. Vigabatrin (VGB) is a novel antiepileptic drug effective as adjunctive therapy in patients with partial seizures. In this study, the efficacy and tolerability of VGB as adjunctive therapy were evaluated in patients with refractory epilepsy. Adult patients with a definite diagnosis of complex partial seizures and/or partial seizures secondarily generalized were recruited from 10 Canadian centres. Patients were randomized to receive either active medication or placebo in a double- blind fashion and entered a 36-week titration and maintenance phase with regularly scheduled visits. Both efficacy parameters and safety assessments were monitored. Clinical laboratory, evoked potential studies, MRI, and neuropsychological tests were also performed. Forty-eight percent of VGB-treated patients vs. 26 percent of placebo-treated patients had a 50 percent or greater reduction in the frequency of complex partial seizures and partial seizures secondarily generalized. Vigabatrin was well tolerated by the majority of patients. Minor neurological side effects were observed in a number of patients in both treatment groups. No serious systemic toxicity was observed. No changes in evoked potential studies or MRI findings were noted. Vigabatrin was found to be an effective and well-tolerated antiepileptic drug when used as adjunctive therapy in patients with difficult to control complex partial seizures and for partial seizures secondarily generalized. Vigabatrin is a selective irreversible inhibitor of the GABA- degradating enzyme GABA transaminase and has shown efficacy in a number of clinical trials in patients with difficult to control partial seizures. Vigabatrin has been found most effective against complex partial and secondarily generalized tonic-clonic seizures in both adults and children. Vigabatrin has also been shown to reduce infantile spasms secondary to various aetiologies and is most effective in spasms associated with tuberous sclerosis. The aim of this study was to further extend the clinical experience with VGB as adjunctive therapy in the treatment of adult patients with difficult to control complex partial seizures and/or partial seizures secondarily generalized. In addition to the assessments of efficacy and tolerability to VGB, neuropsychological evaluations were also carried out.
                Copyright 2000 BEA Trading Ltd. To assess the effectiveness of a "stress dose" of hydrocortisone for rescue treatment of refractory hypotension and adrenocortical insufficiency of prematurity in very low birth weight (VLBW) infants. We hypothesized that significantly more VLBW infants who were receiving dopamine > or =10 microg/kg per min could wean off vasopressor support 72 hours after treatment with hydrocortisone.
                A double-blind, randomized, controlled study was conducted in a university neonatal center. Forty-eight VLBW infants who had refractory hypotension and required dopamine > or =10 microg/kg per min were randomly assigned to receive a stress dose of hydrocortisone (1 mg/kg every 8 hours for 5 days; n = 24) or an equivalent volume of the placebo solution (isotonic saline; n = 24).
                The baseline clinical characteristics were similar between the groups. Serum cortisol concentrations were very low immediately before randomization in both groups of infants. Significantly more VLBW infants who were treated with hydrocortisone weaned off vasopressor support 72 hours after starting treatment. The use of volume expander, cumulative dose of dopamine, and dobutamine were significantly less in hydrocortisone-treated infants compared with control infants. In addition, the median duration of vasopressor treatment was halved in hydrocortisone-treated patients. Two versus 11 infants in the hydrocortisone and control groups required a second vasopressor for treatment of refractory hypotension. The trend (linear and quadratic) of the mean arterial blood pressure was also significantly and consistently higher in hydrocortisone-treated infants.
                A stress dose of hydrocortisone was effective in treating refractory hypotension in VLBW infants. Although routine and prophylactic use of systemic corticosteroids could not be recommended because of their potential adverse effects, this relatively low dose of hydrocortisone would probably be preferable to high-dose dexamethasone for treatment of refractory hypotension in emergency and life-threatening situations. Twenty-four newly diagnosed and previously untreated infantile spasm patients were treated for 3 weeks with either methysergide (12 patients) or alpha-methylparatyrosine (12 patients). Response to therapy was determined objectively with 24-h polygraphic/video monitoring techniques and was defined as cessation of spasms and disappearance of the hypsarrhythmic EEG pattern. Two (17%) of the patients treated with alpha-methylparatyrosine responded to therapy, and one (8%) of the methysergide-treated group showed a response. To assess the clinical impact of monitoring serum concentrations of antiepileptic drugs (AEDs) in patients with newly diagnosed epilepsy.
                One-hundred eighty patients with partial or idiopathic generalized nonabsence epilepsy, aged 6 to 65 years, requiring initiation of treatment with carbamazepine (CBZ), valproate (VPA), phenytoin (PHT), phenobarbital (PB), or primidone (PRM) were randomly allocated to two groups according to an open, prospective parallel-group design. In one group, dosage was adjusted to achieve serum AED concentration within a target range (10-20 microg/ml for PHT, 15-40 microg/ml for PB, 4-11 microg/ml for CBZ, and 40-100 microg/ml for VPA), whereas in the other group, dosage was adjusted on clinical grounds. Patients were followed up for 24 months or until a change in therapeutic strategy was clinically indicated.
                Baseline characteristics did not differ between the two groups. Most patients with partial epilepsy were treated with CBZ, whereas generalized epilepsies were most commonly managed with PB or VPA. PHT was used only in a small minority of patients. A total of 116 patients completed 2-year follow-up, and there were no differences in exit rate from any cause between the monitored group and the control group. The proportion of assessable patients with mean serum drug levels outside the target range (mostly below range) during the first 6 months of the study was 8% in the monitored group compared with 25% in the control group (p < 0.01). There were no significant differences between the monitored group and the control group with respect to patients achieving 12-month remission (60% vs. 61%), patients remaining seizure free since initiation of treatment (38% vs. 41%), and time to first seizure or 12-month remission. Frequency of adverse effects was almost identical in the two groups.
                Only a small minority of patients were treated with PHT, the drug for which serum concentration measurements are most likely to be useful. With the AEDs most commonly used in this study, early implementation of serum AED level monitoring did not improve overall therapeutic outcome. and the majority of patients could be satisfactorily treated by adjusting dose on clinical grounds. Monitoring the serum levels of these drugs in selected patients and in special situations is likely to be more rewarding than routine measurements in a large clinic population. Carbamazepine (CBZ) is a drug of choice for the treatment of simple or complex partial seizures and secondary generalized seizures in adults and children. Vigabatrin (VGB) is a relatively new second line antiepileptic drug and was first registered for use in Poland more than ten years ago. Few reports have been published on the comparison of efficacy of VGB in children with epilepsy. The objective of this study is to evaluate the safety, efficacy and EEG effects of initial VGB monotherapy compared with initial CBZ monotherapy in children with newly diagnosed epilepsy. We present results of a prospective, outpatient and open study carried out in the University Hospital Center in Białystok. Twenty-six children with partial epilepsy treated with VGB and 28 patients treated with CBZ were studied. The evaluation of the efficacy of the two drugs did not reveal any significant differences. Very good (reduction > 75%) seizure control was achieved in 22 out of 26 patients (84.6%) in the VGB group. One patient had a 50-75% decrease of seizures (good effect), similarly one child had a 25-50% reduction of seizures (mild effect). In two patients, we observed increased seizures (myoclonic jerks). Very good seizure control was achieved in 17 out of 28 patients (60.7%) in the CBZ group. Good seizure control was achieved in 5 out of 28 patients (17.8%) and mild control was seen in two children. No improvement was observed in 4 (14%) of the patients. The EEG background activity was improved in VGB-treated patients. No effect on the EEG background activity was observed in CBZ-treated children. VGB seems to be a safe and effective antiepileptic drug as primary monotherapy for epilepsy in children with similar proportion of side effects as CBZ. To compare vigabatrin with carbamazepine as monotherapy in newly diagnosed children with partial epilepsy in order to evaluate the efficacy and tolerability of both drugs.
                Open and randomized with a 2-year follow-up period.
                The Infantile Neuropsychiatric Division of the Regional Pediatric Hospital, Ancona, Italy.
                Seventy children with newly diagnosed partial epilepsy were treated with vigabatrin (38 patients) or carbamazepine (32 patients).
                Vigabatrin, 50 to 60 mg/kg per day, or carbamazepine, 15 to 20 mg/kg per day, split into twice-a-day doses.
                The efficacy and tolerability of vigabatrin were compared with those of the standard treatment (carbamazepine) for this patient group.
                The efficacy of vigabatrin and carbamazepine was similar, with the suggestion of a better side effect profile with vigabatrin.
                Vigabatrin monotherapy should be considered as a monotherapeutic treatment option in patients with newly diagnosed epilepsy. However, more studies are needed to evaluate other issues of concern, such as the cognitive and behavioral adverse effects of antiepileptic drugs, to determine the most suitable therapy.
To date, few well-designed RCTs have considered the treatment of infantile spasms, and the numbers of patients enrolled have been small. In the majority, methodology has been poor, hence it is not clear which treatment is optimal in the treatment of this epilepsy syndrome. Hormonal treatment resolves spasms in more infants than vigabatrin, but this may or may not translate into better long-term outcomes. If prednisolone or vigabatrin is used, high dosage is recommended. Vigabatrin may be the treatment of choice in tuberous sclerosis. Resolution of the EEG features may be important, but this has not been proven. Further research using large studies with robust methodology is required.
