RESUMO

We systematically quantified excess mortality in epilepsy patients by cause of death using the population-attributable fraction and epilepsy-attributable years of potential life lost (YPLL) by age 75 years at ages 15 and over. We updated and undertook a re-review of mortality studies from our previous systematic review following PRISMA guidelines to identify cohort studies of general epilepsy populations reporting a relative risk (RR) of death by cause relative to the background rates in the population. Studies on epilepsy prevalence were identified through published reviews. Country-specific mortality figures were obtained from the WHO World Mortality Database. We performed a pooled analysis with the DerSimonian-Laird random effects method. In countries with very high Human Development Indices, epilepsy contributed to 0.5-1.1 % of all deaths in the total population. Among external causes, suicides (RR 2.9, 95 % confidence interval 2.2-3.8; I(2) 52 %) were the major contributor to YPLL, corresponding to 6.7 % and 4.2 % of excess YPLL due to epilepsy in the United States (US) and in the United Kingdom (UK) in 2010, with 541 (346-792) and 44 (28-65) excess suicide cases, respectively. Fatal accidental falls were more common, with 813 (610-1064) and 95 (71-125) excess deaths in the US and in the UK, but these caused only 2.0 % of excess YPLL as they occurred in older age groups. Suicides were the most important external cause of death in epilepsy patients in terms of excess YPLL, whereas other external causes were either more common in older ages or caused less excess deaths.

RESUMO

OBJECTIVE: We systematically synthesized the epidemiologic literature on mortality in patients with epilepsy (PWE) by epilepsy-related clinical characteristics with an aggregate data meta-analysis. METHODS: We systematically searched 15 electronic databases, browsed reference lists of pertinent publications, and contacted authors in the field. We were interested in cohort studies that reported the relative risk of death in representative epilepsy populations relative to the general population, with exclusion of highly selected subpopulations of PWE, such as patients with intellectual disabilities or epilepsy surgery series. Search, data abstraction, and study quality assessment with the Newcastle-Ottawa Scale were all performed in duplicate. RESULTS: Pooled mortality was threefold (relative risk 3.33, 95% confidence interval 2.83-3.92) in 38 epilepsy cohorts including 165,879 patients (79.6% from Nordic countries). Among incident cases, idiopathic epilepsies did not associate with materially increased mortality (1.29, 0.75-2.20; 4 studies), whereas mortality was almost twofold in cryptogenic epilepsy (1.75, 1.20-2.54; 5 studies), and highly elevated in patients with symptomatic epilepsy (4.73, 3.27-6.83; 12 studies) and especially in epilepsies due to congenital or developmental causes (10.3, 4.03-26.2; 2 studies). Newly diagnosed patients who attained seizure freedom did not have elevated mortality (0.97, 0.73-1.30; 2 studies). CONCLUSION: Excess mortality was highly related to the etiology of epilepsy in all ages. In adult patients without neuroradiologic abnormalities or other identifiable cause of epilepsy, only patients with cryptogenic epilepsy exhibited excess mortality. Risk of premature death was lowest in idiopathic epilepsy and in PWE who attained seizure freedom.
