Prospective study of first-line vigabatrin monotherapy in childhood partial epilepsies.

This was a prospective open comparative pilot study to assess the efficacy and tolerability of first-line vigabatrin monotherapy in childhood partial epilepsies. Two groups of patients were recruited over the same period. The vigabatrin monotherapy group comprised 40 patients (18 male, 22 female; mean age at last visit 7.5 years); the comparative carbamazepine monotherapy group comprised 40 consecutive clinic patients (22 male, 18 female; mean age at last visit 7.8 years). Seizures disappeared in 82% of vigabatrin patients and in all carbamazepine patients with idiopathic partial epilepsy, and in 50% of vigabatrin patients and 55% of carbamazepine patients with symptomatic partial epilepsy. Interictal EEG abnormalities decreased in vigabatrin patients more than in carbamazepine patients (P < 0.05). Tolerability was good in vigabatrin patients, but four out of 37 showed mild irritability by the end of the trial. Persistent sedation was observed in eight of the 40 patients receiving carbamazepine. No patient had drug therapy discontinued because of side-effects. During vigabatrin long-term monotherapy, efficacy and good clinical tolerability were maintained. These results suggest that vigabatrin may be an alternative first-line treatment for childhood partial epilepsies. Further blinded comparative randomized trials are needed.

Benign infantile familial convulsions: natural history of a case and clinical characteristics of a large Italian family.

We present a patient (3 months old) with partial and generalized seizures who has a family history of seizures with a onset during the first 12 months of life. We diagnosed benign infantile familial convulsions (BIFC) and we did not introduce any antiepileptic therapy. We present clinical data of her family where 18 out of 35 members were affected; to our knowledge this is the largest family with BIFC. BIFC is transmitted as an autosomal dominant trait; recently it has been reported that the gene for BIFC maps to the long arm of chromosome 19. We conducted linkage analysis in our family providing significant exclusion of linkage between the BIFC locus phenotype and chromosome 19 markers, suggesting that a second locus is involved in this family.

Benign partial epilepsy in infancy with complex partial seizures (Watanabe's syndrome): 12 non-Japanese new cases.

International epilepsy classification includes different epileptic syndromes with favourable outcomes in pediatric age. In addition to these, other forms probably exist and in various papers in international literature they are proposed as new entities. This article presents a survey of benign complex partial epilepsy in infancy, a new epileptic syndrome first proposed by Watanabe, in 1987. Our work represents the only description of non-Japanese cases although similar but familial cases had been referred by Vigevano in 1992. We present data for 12 children (aged up to 9 years) followed over 2 years who had all the typical clinical features characterizing Watanabe's cases. For all of them we obtained EEG seizure recordings demonstrating the partial nature of their fits, arising from occipital or temporal regions. Interictal EEG were completely normal, both in waking and sleep. Evolution demonstrated benign outcome and all the children are seizure-free (eight of them have already stopped all medication) and all have normal psychomotor development.

Intravenous immune globulin in the treatment of intractable childhood epilepsy.

Many clinical and experimental data strongly support the role of immune mechanisms in the pathogenesis of childhood epilepsy. Following Pechadre's first observations with intramuscular immune globulin (IMIG), intravenous immune globulin (IVIG) has been employed in some forms of intractable childhood epilepsy (ICE), mainly in West syndrome (WS) and Lennox Gastaut syndrome (LGS), with good results. So far, 373 children suffering from ICE have been treated in 29 studies and 174 have responded favourably. Although these studies are heterogeneous and controls are lacking, most authors report similar responsiveness ranging from 30% to 50%. Several mechanisms have been suggested to account for the efficacy of IVIG in ICE including antiviral effect, substitutive therapy in patients with concomitant humoral immunodeficiency, idiotype-anti-idiotype interaction or a neuromodulant effect. To better define the real efficacy of IVIG in ICE in paediatric patients, a randomized, multicenter, double-blind clinical trial was started in 1993, including only patients suffering from WS and LGS. To date, only one double-blind trial had been carried out (with both adult and paediatric patients); it showed a clear trend in favour of IVIG treatment but lacked statistical significance, perhaps because of the small and heterogeneous sample. Controlled multicentre studies on well-defined populations are needed and patients with WS and LGS are probably the best candidates.

IgG2 deficiency and intractable epilepsy of childhood.

Twelve children with intractable childhood epilepsy (ICE) were treated with high-dose intravenous immunoglobulins every 21 days for 6 months after immunologic and neurologic evaluations had been carried out. 50% (6/12) were found to have a deficiency of serum IgG2 and all but 1 of these responded to treatment with marked reduction in the daily number of seizures assessed both clinically and electroencephalographically. The response to treatment was, in fact, significantly higher in the children with IgG2 deficiency than in the others. IgG4 deficiency, observed in 5 children, did not affect treatment response. It is suggested that IgG2 deficiency may predispose to some form of viral encephalitis which may trigger an immune mechanism leading to the ICE.
