Adrenocorticotropic Hormone Versus Prednisolone in the Treatment of Infantile Spasms Post Vigabatrin Failure

The Child Neurology Society/American Academy of Neurology practice parameter has recommended adrenocorticotropic hormone or vigabatrin in the short-term treatment of infantile spasms. When vigabatrin is unavailable or ineffective and adrenocorticotropic hormone is not a treatment option because of the prohibitive cost, other forms of corticosteroids have been considered in the treatment of infantile spasms. This retrospective study reviewed the Hospital for Sick Children's experience with the short-term effectiveness of prednisolone versus adrenocorticotropic hormone in patients with infantile spasms who have failed vigabatrin. The results showed that while adrenocorticotropic hormone was more likely to lead to short-term spasm freedom, there was no difference in the likelihood of longer-term spasm resolution without relapse. These findings can guide clinicians in the treatment of infantile spasms post vigabatrin failure.
