ABSTRACT
Epilepsy is the most common acquired chronic neurological disorder; each year about 1 in a 1000 patients with chronic epilepsy die suddenly, unexpectedly, and without explanation, even with postmortem examination (SUDEP). Seizure incidence is approximately 10% in patients with chronic renal failure and hemodialysis-associated seizure has been considered to be a common complication of people on hemodialysis treatment. Considering this, we evaluated the incidence of seizures in 189 patients under dialytic treatment.

Of the many risk factors suggested for sudden unexpected death in epilepsy (SUDEP), higher frequency of seizures is a very consistent issue. Following this reasoning, it has been established that hemodialysis-associated seizure is a complication of dialysis procedure. Based on these facts, this study investigated a possible association between cardiovascular abnormalities and SUDEP among patients with chronic renal insufficiency in regular hemodialysis program. For that, a retrospective medical history of 209 patients was reviewed to investigate the occurrence of convulsive seizures and EKG abnormalities during dialytic program. Three patients presented generalized tonic-clonic seizures, one had partial seizure with secondary generalization, and one presented unclassified seizure. Any EKG abnormalities and SUDEP event were found in all patients evaluated. In conclusion, the present findings demonstrated uncommon the occurrence of seizures and also SUDEP. Probably, the main justification to not allow us to demonstrated a direct relation between SUDEP and cardiovascular diseases in hemodialysis are the reduced number of cases examined.

Um dos principais fatores de risco para a morte súbita e inesperada na epilepsia (SUDEP) é a alta freqüência de crises epilépticas. Seguindo este raciocínio, tem sido estabelecido que as crises epilépticas associadas à hemodiálise seja uma complicação do procedimento dialítico. Baseado neste fato, este estudo investigou uma possível associação entre anormalidades cardiovasculares e SUDEP nos pacientes com insuficiência renal crônica em um programa regular de hemodiálise. Para isto, um histórico médico retrospectivo de 209 pacientes foi revisado para avaliar a ocorrência de crises epilépticas e possíveis anormalidades no ECG durante o programa de diálise. Três pacientes apresentaram crises tônico-clonica generalizadas, um apresentou crise parcial com generalização secundária e um apresentou crise não-classificada. Não detectamos anormalidades no ECG e ocorrência de SUDEP em todos os pacientes avaliados. Em conclusão, na presente amostra constatou-se como rara a ocorrência de crises epilépticas e SUDEP. Provavelmente, o número reduzido de casos avaliados tenha sido responsável pela não observação de uma relação direta entre SUDEP e as doenças cardiovasculares na hemodiálise.
