Infantile spasms in a patient with williams syndrome and craniosynostosis

Area of Science:

• Genetics
• Neurology
• Pediatrics

Background:

• Williams syndrome is a genetic disorder characterized by a distinct facial appearance, cardiovascular issues, developmental delay, and other medical problems.
• Infantile spasms and craniosynostosis are serious conditions that can occur in infants, requiring prompt diagnosis and management.

Observation:

• A 6-month-old infant with infantile spasms and craniosynostosis was treated with adrenocorticotropic hormone (ACTH), which controlled seizures but worsened ventricular hypertrophy.
• Following ACTH cessation, seizures recurred, accompanied by typical Williams syndrome features: elfin facies, failure-to-thrive, developmental delay, dental malformations, and congenital heart defects.
• High-resolution chromosome analysis confirmed Williams syndrome with an interstitial deletion of 7q11.22-q11.23.

Findings:

• Thyrotropin-releasing hormone (TRH) therapy demonstrated efficacy in reducing infantile spasms and improving electroencephalogram (EEG) findings.
• TRH therapy was well-tolerated, showing no adverse cardiac side effects.
• A slight improvement in psychomotor development was observed with TRH treatment.

Implications:

• This case highlights TRH as a potential therapeutic option for managing seizures in patients with Williams syndrome, offering an alternative to ACTH.
• The findings suggest that TRH may mitigate seizure activity and positively impact neurodevelopmental outcomes in this specific genetic disorder.
• Further research into TRH's role in managing neurological manifestations of Williams syndrome is warranted, particularly concerning its long-term efficacy and safety profile.
