Abstract
We investigated the factors associated with renal dysfunction in leprosy patients from Brazil. We report on a historical cohort of leprosy patients followed in two hospitals in Fortaleza City in northeastern Brazil. The factors associated with renal dysfunction were investigated. A total of 923 patients were included, with a mean age of 41.5 ± 19.1 years, and 53.3% were male. Renal dysfunction was found in 35 cases (3.8%). Proteinuria was found in 4.8% of cases, haematuria in 6.8% and leukocyturia in 10.4%. Factors associated with renal dysfunction by multivariate analysis were: reaction episode (odds ratio [OR] = 3.9, P = 0.03), multibacillary classification (OR = 3.5, P = 0.02) and advanced age (OR = 1.04, P = 0.01). Four patients (0.4%) died. Leprosy is associated with renal dysfunction, especially in older patients and those presenting with reaction episode and multibacillary classification.
