Cocaine use, hypertension, and end-stage renal disease

Am J Kidney Dis. 2001 Sep;38(3):523-8. doi: 10.1053/ajkd.2001.26845.

Abstract

Cocaine use has been associated with both acute renal failure and hypertension (HTN), but only recently have data suggested it may lead to a chronic insidious form of renal failure. We designed a cross-sectional study to compare the association of cocaine use in hemodialysis patients with and without a diagnosis of HTN-related end-stage renal disease (HTN-ESRD). Two hundred one black patients from two outpatient hemodialysis units in an urban community were evaluated. There were 193 eligible patients, 106 men and 87 women, aged 49.28 +/- 14.4 years. A history of significant cocaine use before dialysis was reported by 55 of 193 subjects (28.5%). A diagnosis of HTN-ESRD was reported in 49 of 55 cocaine users (89.1%) compared with 64 of 138 nonusers (46.38%; odds ratio, 9.44; 95% confidence interval, 3.79 to 23.49; P < 0.0005). Of the 113 subjects with HTN-ESRD, 49 subjects (43.4%) had a history of cocaine abuse, either alone or in combination with other drugs. Subjects with HTN-ESRD with cocaine use were younger than those without cocaine use (40.7 +/- 9.0 versus 53.8 +/-15.3 years; P < 0.0005) and had a shorter reported duration of HTN (5.3 +/- 5.4 versus 12.7 +/- 9.8 years; P < 0.0005, adjusted for age and sex). In our urban dialysis population, a clinical diagnosis of HTN-ESRD was strongly associated with a history of cocaine use and earlier onset of ESRD. Cocaine should be considered as a cause of ESRD in patients without a clear cause of renal failure.
