Kala azar (KA) is one of the most important tropical diseases. More so is the issue of KA in pregnancy. In this retrospective study we tried to find out the out come of pregnant patient treated with Sodium Antimony Gluconate (SAG) for KA in one of the most endemic area of Bangladesh, Fulbaria. SAG is the available and registered drug for treatment of KA patient with pregnancy in Bangladesh. A total of 16 pregnant women presented with KA during the study period of 2005 to 2009. Out of the 16 patients 11 had abortion and they were all with in the 16 to 22nd week of pregnancy. The abortion took place mostly on the 22nd to 24th day of treatment when the patient had become afebrile. Rest of the 5 patients was in their 30 to 34th week of pregnancy and had good obstetric outcome. All the 16 patients were clinically cured at the end of treatment. No follow up records were available and there was no data regarding the 5 children. It is of our opinion that the abortions were induced by SAG and therefore we recommend that SAG should not be used in early or mid pregnancy for treating KA.
