Abstract Background: Leprosy or Hansen’s disease (HAD) undoubtedly remains an emergency in certain countries. It is an ancient deforming disease caused by Mycobacterium leprae. The countries with the highest endemic leprosy rate in 2000 were Brazil, India and Madagascar. In Italy, the old epidemic has been defeated and there are approximately 400 patients under constant monitoring with three to four new cases per year involving Italian residents. The kidney is one of the target organs during the splanchnic localization of leprosy. The histopathological renal lesion spectrum includes glomerulonephritis (GN), renal amyloidosis (RA) and interstitial nephritis (IN). Both proteinuria and chronic renal failure are the main clinical expressions of renal damage in leprosy. To the best of our knowledge, very little is reported concerning end-stage renal disease (ESRD) in leprosy patients both in the most important national and international renal registries and in the available literature. This study aimed to report the longterm experience of our department in this field. Methods: To achieve this, we analyzed retrospectively the HAD Center (Gioia del Colle) database at our hospital. Results: Eight leprosy patients were dialyzed from 1980 to June 2003 (six males and two females), with a mean age of 61.0 ± 8.9 SD yrs (range: 51-76) and a mean HAD duration of 36.1 ± 5.1 yrs. The first clinical nephropathy manifestations were non-nephrotic proteinuria associated with chronic renal failure in four patients, and nephrotic proteinuria in four patients. Kidney biopsies performed in three patients showed two had RA, and one had IN. Two patients were treated initially by peritoneal dialysis; they were then switched to hemodialysis (HD) after 3 and 10 months because of recurrent peritonitis. HD treatment lasted 40.6 ± 31.4 months (range: 9-101). Six patients died, one due to hyperkalemia, one because of a technical dialysis accident, and the remainder due to causes unrelated to the dialysis treatment. Two patients are still alive, treated with HD for 17 and 44 months. Conclusions: Uremia represents a late complication of leprosy and has a multifactorial genesis, although RA is among the most frequent causes, conventional bicarbonate HD appears to offer good results in the treatment of uremia in leprosy patients.
