Implication

Interventional study reveals high efficacy of interferon gamma combined with pentavalent antimony in visceral leishmaniasis, suggesting an effective strategy for severe or refractory cases.

Key Points

To evaluate the efficacy and safety of recombinant human interferon gamma combined with pentavalent antimony in patients with refractory or previously untreated severe visceral leishmaniasis.
Administered recombinant human interferon gamma (100 to 400 µg/m²/day) alongside pentavalent antimony (20 mg/kg/day) for 10 to 40 days.
Treated 8 patients with refractory disease unresponsive to prior antimony therapy and 9 patients with previously untreated severe disease (total N=17), with a mean follow-up of 8 ± 1 months.
Treatment led to clinical response in 6 of 8 refractory patients and 8 of 9 previously untreated patients, while 2 refractory patients relapsed and required amphotericin B.
The 14 responders achieved parasite clearance or reduction in splenic aspirates, resolution of anemia and leukopenia, reduced splenomegaly, and no relapse at 8 ± 1 months follow-up, with fever as the only major side effect.
