Spectrum of renal failure in elderly patients.
This prospective study was undertaken to study the spectrum of renal failure and the outcome in elderly patients. Patients included in the study group were elderly (age>60 years) who either attended outpatient renal clinic and or were hospitalized. Renal failure was classified as acute renal failure (ARF), rapidly progressive renal failure (RPRF) and chronic renal failure (CRF). A total of 4255 elderly patients were seen, of these 236 (5.5%) had renal failure. Mean age was 65.1+/-4.2 years (60-86 years). CRF was the commonest, seen in 137 (58.1%) followed by ARF 69 (29.2%) and RPRF in 30 (12.7%) patients. Diabetic nephropathy was the commonest cause of CRF, seen in 58.4% followed by chronic interstitial nephritis in 9.5% and chronic glomerulonephritis in 8.7% of patients. Of 137 patients 53 (38.7%) presented in end stage renal disease (ESRD). Of these 41 (77.3%) were initiated on maintenance hemodialysis and 12 (22.6%) on continuous ambulatory peritoneal dialysis. Only 15 patients were on dialytic support at the end of 1 year. Sepsis contributed to ARF in 75.4% of cases. Forty of 69 patients (57.9%) needed dialytic support. Forty (57.9%) were critically ill, defined as presence of two or more organ system failures (excluding renal failure). Forty two patients (60.9%) died patients. Acute interstitial nephritis (AIN) was the commonest cause of RPRF seen in 10 (33.3%) patients followed by vasculitis in 7 (23.3%). Myeloma cast nephropathy contributed towards RPRF in 20% of patients. Of 30 patients, 10 (33.3%) reached ESRD at end of 3 months of follow up, 4 (13.3%) died due to sepsis. Only 2 showed complete recovery while 14 (46.6%) had partial improvement. AIN patients had a relatively better outcome.
