Abstract

Background: Diabetes ketoacidosis (DKA) is the leading cause of death in children with diabetes, especially when it is complicated by cerebral edema. The predictors of CNS dysfunction/injury are largely unknown. In many neurological disorders, neuron-specific enolase (NSE) is a marker of neuronal damage.
Objective: This study aimed to investigate the role of serum neuron-specific enolase as a marker of neuronal damage in patients with DKA.
Patients and methods: A cross-sectional study with 90 DKA patients (aged 9.58 ± 2.89 years) presenting to Pediatric Intensive Care Unit (PICU), Children Hospital Zagazig University. Patients subjected to clinical history and examination including Glasco coma scale (GCS), blood glucose, serum electrolytes, blood PH and computed tomography of the brain for children with disturbed consciousness. Blood NSE at admission (baseline point) and after 24 hours of starting treatment of DKA (2-time points).
Results: There was a significant difference between NSE level on admission and NSE level 24 hours after start of treatment. Patients with low GCS scores had higher serum NSE at baseline and 2-time points than those with normal CGS (P=0.001; P=0.053). Patients with moderate and severe DKA had higher NSE at baseline and 2-time points in comparison with those with mild DKA (P=0.001; P=0.098).
Conclusions: Children with moderate to severe DKA and impaired consciousness had higher serum NSE. The high levels of NSE in patients with abnormal GCS, in the absence of cerebral edema on brain imaging indicate that NSE is a reliable marker of neuronal injury.
