Abstract

Objective The aim of the study is to examine the incidence and risk factors for death among neonates who developed neonatal seizures (NS) in an ethnically distinctive community with high consanguinity rate in Israel.

Methods Retrospective study was conducted at a single institution on data between January 2001 and January 2016. All neonates diagnosed with NS developed up to age 28 days were included. Mortality was defined as death within the first year of life.

Results Of all 69,460 neonates born during the study period, 118 (1.7 per 1,000 live births) developed NS; 35 (29.7%) died within the first year while 83 (70.3%) survived. The leading causes of death were developmental brain malformation (31.4%), genetic/metabolic (20%), hypoxic ischemic encephalopathy (20%), intracranial hemorrhage (11.4%) and infections (11.4%). Any consanguinity between the parents was found in 18 and 14.6% among the survivors and deceased groups, respectively (p = 0.24). Developmental brain malformations that lead to death were present in 3.6 and 31.4% in the survivors and deceased groups, respectively (p = 0.001; relative risk 8.70; 95% confidence interval 2.58–29.27). Stepwise backward logistic regression analysis revealed that developmental brain malformations (p < 0.0001), use of more than one antiepileptic medication (p = 0.006), and multiorgan failure (p = 0.004) were significant risk factors that predicted death.

Conclusion The results of the current study show that developmental brain malformations that cause NS were the leading risk factor for death.

Characteristics of the community examined may determine the major risk factors for neonatal seizures and as a consequence negatively affect the neonatal mortality rate.
