Data on the efficacy and safety of pentavalent antimony in the treatme
nt of visceral leishmaniasis during pregnancy are scanty. A case of vi
sceral leishmaniasis in a 39-year-old woman in the second trimester of
pregnancy is reported here. The patient was hospitalized in poor cond
ition with high fever and pancytopenia which lad lasted for 6 weeks. A
bone marrow aspirate revealed numerous amastigotes and serodiagnosis
for Leishmania was positive at a high titer. The patient was successfu
lly treated with meglumine antimoniate at a daily dose of 850 mg of an
timony for 20 days. She delivered at term a healthy female baby who re
mains in good condition at 18 months of age. Thus a dose of 850 mg of
antimony, which is lower than that presently recommended, seems to be
effective and non toxic to the fetus when administered at the second t
rimester of pregnancy.
