Hypertension due to ACTH treatment for lissencephaly with a novel PAFAH1B1 variant

Abstract

Background

Many patients with lissencephaly present with infantile epileptic spasms syndrome (IESS) or West syndrome and require adrenocorticotrophic hormone (ACTH) treatment. The difference of adverse events of ACTH treatment between lissencephaly and other disorders is unknown.

Case presentation

We report the case of an infant with lissencephaly and IESS followed by severe hypertension with cardiac hypertrophy after ACTH treatment, requiring continuous administration of antihypertensive drugs. The infant was delivered at 39 weeks of gestation with a birth weight of 2484 g and was admitted to the neonatal intensive care unit for transient tachypnea. Brain MRI showed posterior predominant agyria compatible to classical lissencephaly grade 2. He harbored a novel de novo variant of PAFAH1B1 or LIS1 gene, c.485G>A, p. (Gly162Asp). At the age of 5 months, he developed epileptic spasms with hypsarrhythmia on electroencephalogram, leading to the diagnosis of IESS. ACTH and vitamin B6 treatments were effective for seizures and hypsarrhythmia. However, the patient had hypertension (138/100 mmHg) and cardiac hypertrophy and required continuous administration of nicardipine intravenously(0.6–1.0 μg/kg/min).

Conclusion

Patients with lissencephaly might be susceptible to severe cardiac adverse events with ACTH treatment.
