Expert Opinion :
Wonderful replies. There have been very few cases of congenital leishmaniasis reported in the world. There have also been instances where mother has been asymptomatic but had antibody for leishmania positive {Pediatrics. 1999 Nov`104{5}:e65.} with history of travel to endemic area previously.
In your patient also we suspected congenital transmission of the leishmania but mother`s kalaazar elisa was negative for antibody.
Transfusion transmitted leishmaniasis {TTL} has also been reported in literature. L. donovani are expected to remain present in the blood for an undefined period between the bite of sand fly and their final localization to the target organs.The duration of asymptomatic parasitaemia varies with the infecting species. For Leishmania donovani this period varies from 1-14 months. For other species this period varies from two to eight weeks, although some cases have been reported following a one-year incubation period.
Thus, it looks like transfusion asscoiated leishmaniasis in this child.
Could it still be congenital leishmaniasis where the mother`s antibody titres may have become undetectable_?
