Infantile Epileptic Spasms Syndrome Due to Neonatal Hypoglycemic Brain Injury: A Retrospective Audit

Area of Science:

• Pediatric Neurology
• Neonatology
• Epileptology

Background:

• Infantile epileptic spasms syndrome (IESS) is a severe epilepsy syndrome in infants.
• Identifying the etiology of IESS is crucial for prognosis and management.
• Neonatal brain injuries are increasingly recognized as significant contributors to IESS.

Purpose of the Study:

• To determine the leading causes of infantile epileptic spasms syndrome (IESS) in a cohort of children.
• To compare the clinical presentation of IESS secondary to different neonatal brain injuries.
• To highlight the specific features associated with neonatal hypoglycemic brain injury (NHBI) in IESS.

Main Methods:

• Retrospective audit of 56 children diagnosed with IESS.
• Analysis of etiological factors contributing to IESS.
• Comparison of clinical features between IESS cases related to NHBI and hypoxic ischemic encephalopathy (HIE).

Main Results:

• Neonatal hypoglycemic brain injury (NHBI) was the most frequent etiology, accounting for 35.71% of IESS cases.
• Hypoxic ischemic encephalopathy (HIE) was the second leading cause at 25%.
• Other causes comprised 30.3% of cases. Hypotonia, visual concerns, and microcephaly were more pronounced in NHBI-related IESS compared to HIE-related IESS.

Conclusions:

• NHBI is a leading cause of IESS, necessitating early detection and intervention.
• Clinical presentation of IESS varies based on the underlying etiology, with distinct features in NHBI cases.
• Further research into the long-term outcomes of NHBI-related IESS is warranted.
