      BACKGROUND: Antimonials are the mainstay of visceral leishmaniasis (VL) treatment in Africa. The increasing incidence of human immunodeficiency virus (HIV) coinfection requires alternative safe and effective drug regimens. Oral miltefosine has been proven to be safe and effective in the treatment of Indian VL but has not been studied in Africa or in persons with HIV and VL coinfection. METHODS: We compared the efficacy of miltefosine and sodium stibogluconate (SSG) in the treatment of VL in persons in Ethiopia. A total of 580 men with parasitologically and/or serologically confirmed VL were randomized to receive either oral miltefosine (100 mg per day for 28 days) or intramuscular SSG (20 mg/kg per day for 30 days). RESULTS: The initial cure rate was 88% in both treatment groups. Mortality during treatment was 2% in the miltefosine group, compared with 10% in the SSG group. Initial treatment failure was 8% in the miltefosine group, compared with 1% in the SSG group. Among the 375 patients (65%) who agreed to HIV testing, HIV seroprevalence was 29%. Among patients not infected with HIV, initial cure, mortality, and initial treatment failure rates were not significantly different (94% vs. 95%, 1% vs. 3%, and 5% vs. 1% for the miltefosine and SSG groups, respectively). Initial treatment failure with miltefosine occurred in 18% of HIV-coinfected patients, compared with treatment failure in 5% of non-HIV-infected patients. At 6 months after treatment, 174 (60%) of the 290 miltefosine recipients and 189 (65%) of the 290 SSG recipients experienced cure; 30 (10%) of 290 in the miltefosine group and 7 (2%) of 290 in the SSG group experienced relapse, and the mortality rate was 6% in the miltefosine group, compared with 12% in the SSG group. HIV-infected patients had higher rates of relapse (16 [25%] of 63 patients), compared with non-HIV-infected patients (5 [5%] of 131). CONCLUSIONS: Treatment with miltefosine is equally effective as standard SSG treatment in non-HIV-infected men with VL. Among HIV-coinfected patients, miltefosine is safer but less effective than SSG.
    • Successful Miltefosine Treatment of Post-Kala-Azar Dermal Leishmaniasis Occurring During Antiretroviral Therapy.

      The first two patients to be treated with miltefosine for post-kala-azar dermal leishmaniasis (PKDL) are reported. One was a 26-year-old Ethiopian man who had been treated with sodium stibogluconate, for relapsing visceral leishmaniasis (VL), four times between August 2002 and March 2004. In January 2004 this patient was found to be seropositive for HIV and began antiretroviral treatment with stavudine, lamivudine and nevirapine. Five months later he developed clinical PKDL, with extensive cutaneous, conjunctival and oral mucosal involvement. The second patient was a 42-year-old Ethiopian man who was treated for relapsing VL in November 2003. He too was subsequently found to be seropositive for HIV and was treated with stavudine, lamivudine and nevirapine from May 2004. He developed a nodular rash of PKDL over his face and upper body 2 weeks after starting the antiretroviral therapy. Treatment of both patients with oral miltefosine, at 100 mg/day for 28 days, led to the complete regression of their PKDL lesions. When checked 3-6 months after the end of the miltesofine treatment, neither patient showed any signs of VL, PKDL or other HIV-associated disease.
