Filter by:Infantile Spasms, is an rare age-specific epilepsy of early infancy. A 2012 American Academy Neurology/ Child Neurology Society practice parameter update on the medical treatment of infantile spasms concluded: adrenocorticotrophic hormone or vigabatrin may be offered for short-term treatment of infantile spasms. There was insufficient evidence to recommend the use of prednisolone, dexamethasone, and methylprednisolone. The cost of ACTH and the side effects of vigabatrin have led to the consideration of alternative medications to treat infantile spasms. The United Kingdom Infantile Spasms Study (UKISS) in 2004, comparing the efficacy of intramuscular synthetic ACTH to high dose oral prednisolone, showed a response rate of 74% for ACTH and 70% for prednisolone. Since the UKISS paper was published, many institutions in the United States and Australia have used oral prednisolone instead of ACTH, partly due to the exorbitant cost of intramuscular ACTH but also its ease of use and better adverse event profile compared to ACTH. Prednisolone and vigabatrin are both oral medications, which can be initiated promptly upon diagnosis of infantile spasms, expediting treatment and shortening treatment lag time. Because the UKISS trial is the only Class 3 study providing evidence for oral prednisolone in the first-line treatment of infantile spasms, further prospective studies are needed.
Infantile spasms comprise an infantile epileptic encephalopathy characterized by hypsarrhythmia on EEG, and frequent neurodevelopmental regression. Unfortunately the treatment of this disorder remains difficult. The first-line options which include hormonal therapy, i.e., adrenocorticotropic hormone (ACTH) or oral corticosteroids, and vigabatrin are effective in 60-70% of the patients. Hormonal therapy is considered the best available treatment. Vigabatrin being expensive and of limited availability is not a feasible option for most patients in our setting. Also, these are however associated with significant side effects, and high relapse rates. Newer drugs such as topiramate, zonisamide, and levetiracetam have also been evaluated; however these drugs are less effective than ACTH. The ketogenic diet (KD) is a high fat, low carbohydrate diet. It has been used for treatment of intractable childhood epilepsy. The KD has also been shown to be effective for intractable infantile spasms; often after ACTH and vigabatrin have failed. The modified Atkins diet is a non-pharmacologic therapy for intractable childhood epilepsy that was designed to be a less restrictive alternative to the traditional ketogenic diet. This diet is started on an outpatient basis without a fast, allows unlimited protein and fat, and does not restrict calories or fluids. Preliminary data have shown efficacy in refractory infantile spasms. This diet is also ideal for resource-constraint settings with paucity of trained dieticians. Hence this study has been planned to evaluate the efficacy and tolerability of the modified Atkins diet in children with infantile spasms refractory to hormonal treatment in a randomized controlled trial.
The primary objective of the study is to evaluate vigabatrin pharmacokinetics (PK) in neonates receiving vigabatrin for infantile spasms (IS); and to determine the safety of vigabatrin.
