Author information: 1 Instituto Nacional de Salud, Colombia, pzambrano ins. Objective Characterize the foci of visceral leishmaniasis infection in Neiva with a clinical and epidemiological approach. Materials and Methods Six children consulted medical services with hepatosplenomegaly. They were found to have anemia and leukopenia.
The diagnosis was performed by bone marrow five patients and spleen 1 patient aspiration. An active search for cases was carried out in the community. House calls were made in order to carry out educational activities and to collect disease vectors. Results LV was confirmed in seven children. In six of them, the bone marrow or spleen aspirate contained amastigotes. The IIF was positive in 4 patients and negative in 3. One child was detected throught the active community search, confirmed by the clinic with IIF The canine seroprevalence in dogs was 6.
This is the principal vector of LV in Colombia. Conclusions The study showed that two zones of Neiva have children infected with LV. Diagnostic confirmation must include aspiration of bone marrow and IIFs. Treatment with miltefosine was not helpful, but liposomal amphotericin B is an ideal therapy. To control LV, active case searching, community education and vector and reservoir control is necessary.
