Infantile Spasms and Injuries of Prematurity: Short-Term Treatment-Based Response and Long-Term Outcomes

Area of Science:

• Neonatal neurology
• Pediatric epilepsy
• Neurodevelopmental disorders

Background:

• Infantile spasms (IS) are a severe epilepsy syndrome.
• Periventricular leukomalacia (PVL) and intraventricular hemorrhage (IVH) are common in premature infants.
• Limited data exist on treatment and long-term outcomes for IS in premature infants with PVL/IVH.

Purpose of the Study:

• To evaluate early treatment response and long-term outcomes in premature infants with IS and PVL/IVH.
• To identify effective therapies for this specific population.
• To assess the incidence of refractory epilepsy and developmental delay.

Main Methods:

• Retrospective chart review of premature infants (<37 weeks gestation) diagnosed with IS, PVL, and/or IVH.
• Analysis of treatment modalities, spasm resolution, and long-term neurodevelopmental outcomes.
• Median follow-up of 7.1 years.

Main Results:

• Thirteen infants were included (median gestational age 30 weeks).
• Twelve of 13 infants achieved spasm resolution.
• Adrenocorticotropic hormone (ACTH) and vigabatrin were effective in spasm resolution.
• All patients experienced developmental delay; only one had refractory epilepsy.

Conclusions:

• Standard therapies like ACTH and vigabatrin appear effective for IS in premature infants with PVL/IVH.
• Developmental delay is a common long-term outcome.
• Refractory epilepsy may be less frequent than anticipated in this cohort.
