Convulsions in Hemodialysis (HD) Patients with Elevated Polymorphonuclear Leukocyte Elastase (PMNE) Levels

Eight hemodialysis (HD) patients with convulsions of unknown cause were monitored for serum levels of uremic toxins such as methylguanidine (MG), and polymorphonuclear leukocyte elastase (PMNE). Twenty HD patients without convulsions served as controls. In the convulsion group, MG and PMNE were high. In 2 patients, convulsions subsided after daily hemodiafiltration (HDF). Although PMNE was thought to be a mediator of injury in the present series, no significant correlation was found between PMNE and either neutrophil numbers or endotoxin levels. PMNE may indicate the over production of cytokines not associated with serious infection or septicemia. In patients with renal failure and complications of unknown cause, intensified dialysis therapy such as frequent HDF may be useful when combined with treatment of the underlying disease producing the toxins. PMNE measurement is useful in assessing the uremia caused by high cytokine levels and, together with methylguanidin (MG) serum levels, can indicate the severity of the convulsion.
