We report a case of visceral leishmaniasis (VL)/HIV coinfection in a patient undergoing regular antiretroviral therapy and treatment with thalidomide for erythema nodosum leprosum. He presented at a health service with high fever, chills, asthenia, pale skin, lower limb edema, hepatomegaly, and splenomegaly. Visceral leishmaniasis was confirmed by direct examination, and serological and molecular tests. Serum levels of Th1/Th2 cytokines were measured. The patient began treatment with liposomal amphotericin B, with good clinical response; however, VL recurred 6 months later. Treatment was reinitiated, maintaining secondary prophylaxis with liposomal amphotericin B. The patient showed clinical improvement with important recovery of CD4+ T-lymphocyte count.

A rapid and noninvasive rK39 rapid diagnostic test (RDT) is the best and most reliable tool for visceral leishmaniasis (VL) screening in the field. However, splenic and bone marrow aspiration remain two gold standard methods for microscopic identification of Leishmania donovani (LD) bodies and confirmatory diagnosis of VL. Five patients with signs and symptoms of fever, loss of appetite, loss of weight, hepatomegaly, and massive splenomegaly were found to be false positive with the rK39 RDT. These patients were suspected to have chronic myeloid leukemia (CML) because their blood pictures showed a total white blood cell count of > 100,000/mm3 and abnormal cells such as stab, segmented promyelocytes, myelocytes, metamyelocytes, and blast cells. Splenic aspirate and bone marrow were negative for Leishmania donovani bodies. The bone marrow showed myeloid series of cells, that is, myelocytes, metamyelocytes, stab and segmented cells, blast cells, and markedly increased myeloid:erythroid ratio. Later, the CML diagnosis was confirmed in all cases by breakpoint cluster region-tyrosine protein kinase (BCR-ABL) gene positive test results. In this study, the rK39 RDT's false positivity was observed in CML cases. It could have important implications for the differential diagnosis of VL with CML. The rK39 positive test result in CML cases was a serendipitous occurrence; this should be validated further to determine the utility of the rK39 test in the differential diagnosis of VL with CML.

The People's Republic of Bangladesh has been working to eliminate visceral leishmaniasis or Kala-azar cases since there was a memorandum of understanding signed between neighboring countries in 2005. As a part of the elimination activity, 44 cases of Kala-azar were diagnosed and treated in the regional referral center Dhaka Medical College Hospital (DMCH) during the last three years, which is reported here. Confirmed leishmaniasis cases were included. Patients attending this specialized center with different demographic characteristics and varied presentations with laboratory findings were reviewed and recorded in a structured case record form. Ethical clearance was obtained prior to starting the study. A total of 44 patients with leishmaniasis were reviewed. Approximately 89% (n = 39) were New Kala-azar (NKA), 7% (n = 3) were Relapse Kala-azar (Relapse KA), only one case (2%) was Kala-azar Treatment Failure (KATF) and Post Kala-azar Dermal Leishmaniasis (PKDL) for both. The mean age of presentation was 32 years. Forty percent of patients had houses made by mud, 26% by tin shed, and the rest lived in buildings and semi-buildings. The predominant clinical features were fever (90.9%), pallor (88.6%), splenomegaly (81.8%) and hepatomegaly (68.2%). rK39 was positive in 90.7% of cases, and 94.4% of cases were positive for LD bodies on splenic aspirate. Of all, 90.90% were treated with Inj. Liposomal amphotericin B and 9.10% with the combination of Inj. Liposomal Amphotericin B and Inj. Miltefosine. Moving forward to the elimination of leishmaniasis from Bangladesh, the study highlights the status, characteristics and treatment of the disease in the country.
