title: Generic sodium stibogluconate is as safe and effective as branded meglumine antimoniate, for the treatment of tegumentary leishmaniasis in Isiboro Secure Park, Bolivia.
abstract: Human cutaneous leishmaniasis (CL) and mucous leishmaniasis (ML) are highly endemic in Isiboro Secure Park, which lies in the Bolivian department of Cochabamba--an area where branded meglumine antimoniate (Glucantime) is expensive and poorly distributed. The safety and efficacy of generic sodium stibogluconate (SSG), from Albert David Ltd, was therefore explored, in CL and ML cases from the park, who were treated with 20 mg/kg.day for 20 and 30 days, respectively. A questionnaire recording adverse effects was completed by a physician in each treatment centre. Efficacy of treatment was assessed at the end of treatment and at follow-ups 1 month and 3, 6 and 12 months later. Overall, 146 patients completed treatment with SSG in 2003-2004. No fatalities or severe adverse effects were reported but mild to moderate adverse effects were noted in 41 (28%) of the patients. The incidence of adverse effects was significantly higher among the cases of ML than among the cases of CL. Of the 86 patients with CL who completed 6 months of follow-up, 81 (94.2%) were considered to have been clinically cured; a comparable cohort of 69 CL cases who had been treated with Glucantime in 2001-2002 showed a similar frequency of clinical cure (90%). Generic SSG was shown to be safe and efficacious for the treatment of tegumentary leishmaniasis in Bolivia. Being several times cheaper than Glucantime, it could contribute to improving the access of CL and ML patients to treatment, not only in Bolivia but also in other countries of Latin America.
