[Demographic, clinical and therapeutic features of adult visceral leishmaniasis at the Rabta hospital in Tunis (tunisia) from 1983 to 2002].

The purpose of this study was to evaluate in a retrospective analysis, cases of Mediterranean visceral leishmaniasis (VL) diagnosed in adults during a 20-year period in a department of infectious diseases. Demographic data, clinical and laboratory features and therapeutic findings were considered. During the study period, 22 cases of VL were diagnosed, and 6 (27%) were associated with HIV infection. Fever and splenomegaly were observed in all cases. Anaemia was constant. The anti-leishmanial IF titer was positive among 21 patients (95%). Smears from bone marrow aspiration were positive at microscopy in 95% of cases. Zymodeme analysis was carried out in nine isolates. L. infantum zymodeme MON-1 was characterized in all cases. Seventeen patients (77%) received meglumine antimoniate (MA) (20 mg SbV/kg per day) and 5 (23%) patients amphotericin B (AB) (0.5-1 mg/kg per day) for an average period of 25 days (10-49 days). Adverse events occurred in 7 patients (32%), among them 4 received AB. Clinical cure was achieved with success in 21 patients (95%). After a successful MA treatment of the initial episode, VL relapse was observed in one HIV-positive patient. Only one HIV-positive patient died from neurological disorders. VL is rare in adults. However, its incidence is increasing everywhere in the world, because of HIV-related cases. Its prognosis depends on the precocity of diagnosis and treatment.
