Exacerbation of hepatic cirrhosis may trigger admission for epilepsy and status epilepticus.

Abstract

To determine whether acute exacerbations of cirrhotic liver disease are associated with higher odds of readmission for epilepsy or status epilepticus. The New York State Inpatient Database is a statewide dataset containing data on 97% of hospitalizations for New York State. In this retrospective, case-crossover design study, we used International Classification of Diseases, Ninth Revision, Clinical Modification codes to identify index status epilepticus and epilepsy admissions. The primary exposure was defined as admission due to an acute exacerbation of cirrhotic liver disease. The case-crossover analysis tested whether exposure to a hepatic exacerbation within progressively longer case periods (14, 30, 60, 90, 120, 150, and 180days before index admission), compared to control periods 1year before the case period, was associated with readmission for epilepsy or status epilepticus. The odds ratio for subsequent admission for epilepsy after exposure to an acute exacerbation of cirrhotic liver disease was significant in the 30-day window at 2.072 (95% confidence interval [CI] = 1.095-3.92, P=.0252) and peaked in the 150-day window at 2.742 (95% CI = 1.817-4.137, P<.0001). In the status epilepticus group, all case periods demonstrated significantly elevated odds of subsequent admission following hepatic exacerbation. Hepatic exacerbations are associated with increased odds for hospital admissions for epilepsy and status epilepticus across several timeframes.
