Abstract

Octogenarians represent the fastest growing group of patients on hemodialysis. These patients were previously treated with conservative measures, while they were believed to have too poor prognosis on renal replacement therapy. We investigated clinical characteristics and outcome of patients prospectively after at least 2 years of follow-up. Six male and six female patients who were older than 80 years at the start of hemodialysis were followed up. Their clinical characteristics, comorbidities, etiology of renal disease, nutritional status, complications, vascular access, hospitalizations, compliance and outcome were recorded. The primary renal disease was unknown in 42.8% of patients. All patients had one or more comorbid conditions. Dialysis was initiated in an emergency situation in 64.3%. Vascular access was long-term hemodialysis catheter in 71.4%. Only 14.2% of them received erythropoietin. There were no major bleedings with reduced doses of heparin. The most common complications were catheter-related ones (infections, ruptures). All patients together required seven hospitalizations per year (0.58 per patient). The octogenarians tended to be underdialyzed with the mean adequacy of dialysis (Kt/V) 0.92. The 1-year survival was 71.4%, and 2-year survival was 50%, i.e., they had good survival on hemodialysis. Most of them died from causes that were not related to the uremia. Their treatment requires a careful planning of renal service expansion while more octogenarians who need renal replacement treatment may be expected.
