Abstract
A prospective study of all new cases of chronic renal failure (CRF) including inservice referrals was done at our hospital over a period of 1 year from May 1994 to April 1995. The diagnosis of CRF was based on clinical, laboratory, and radiological features. Kidney biopsies were done when indicated. The patients were subdivided into various etiologic groups of primary renal disease according to standard criteria. There were a total of 835 cases of CRF with a median age of 43 years (range 10 days to 90 years); 67.8% of them were men. Glomerulonephritis (28.6%), diabetic nephropathy (23.2%), and interstitial nephritis (16.5%) were the most common causes of CRF, followed by obstructive nephropathy (6.4%), benign nephrosclerosis (4.1%), and polycystic kidney disease (2%). However, in patients more than 40 years of age, diabetic nephropathy was the most common cause (36.8%). The cause of CRF was unknown in 16.2% of the cases. One hundred twenty-one patients (14.5%) had an acute deterioration of their underlying renal dysfunction at presentation. This was most commonly due to accelerated hypertension (26.1%), infection (22.4%), volume depletion (20.1%), and drugs (14.9%). Anti-inflammatory drugs were the most common drugs responsible for the acute decline in renal function. One year after their initial presentation, of the 512 patients (61.3%) with end stage renal disease, 12.5% had died, 17% had received a kidney allograft, 12.7% were on some form of maintenance dialysis, and 295 patients were lost to follow-up. Of the 323 patients with less severe illness, 7 died, 209 were on outpatient treatment, and 107 patients were lost to follow-up. We conclude that the pattern of CRF in India does not differ greatly from that in the developed countries. However, it carries a poorer prognosis due to late referral and limited availability and affordability of renal replacement therapy in India.
