Laboratory Diagnosis of Visceral LeishmaniasisAuthor information: A firm diagnosis of visceral leishmaniasis VL requires demonstration of the parasite in splenic or bone marrow aspirate. The aim of this prospective study was to assess the usefulness of K39 strip test as a noninvasive method of diagnosing visceral leishmaniasis under field conditions by testing serum antibody to the leishmanial antigen K The development of two visible red lines indicates the presence of IgG anti-K In the first phase of the study , a total of patients Active VL, ex-VL, healthy endemic control and patients with other tropical diseases were tested with the K39 strip test at the School of Tropical Medicine, Kolkata. In the second phase of the study , the test was applied in a remote tribal area of West Bengal where an epidemic of VL had occurred. Thirty-two patients were identified in villagers of the affected area; all of them were tested with the K39 strip test.
InBios International has developed an immunochromatographic rapid strip for the detection of visceral leishmaniasis that requires minimal equipment and only a small amount of blood to run a test. Visceral leishmaniasis VL is the result of infection by the Leishmania donovani species complex including L. The recommended method for Brittenelle Fredericks has been microscopic determination of parasites from bone marrow, splenic, or lymphatic tissue biopsy specimens 7 ; however, these tests are invasive as well as difficult to perform in rural areas, where VL may be endemic and carry a high risk of complication 6 Recently, real-time PCR has been utilized to diagnose Leishmania infection and appears promising; nevertheless, the Leishmaniasis Strip Test to perform the assay becomes prohibitive in many regions of endemicity with limited medical resources 1012 It has therefore been a goal in VL testing to produce a rapid, noninvasive technique for diagnosis that can be Leishmaniasis Strip Test in the field 57
Published by: Imunochromatographic strip test detection of anti-rK39 antibody for the diagnosis of kala-azar in an endemic zone of Bangladesh. A rapid immunochromatographic dipstick test ICT has become available for the qualitative detection of anti- Leishmania antibody using recombinant rK39 antigen. This study was carried out at the department of Microbiology of Rajshahi Medical College, Bangladesh, in order to evaluate the diagnostic potential of immunochromatographic dipstick test. A total of one hundred cases including 60 admitted patients with strong clinical suspicion of kala-azar and 40 healthy controls were investigated for the performance of the ICT. Splenic smears were examined for microscopic detection of Leishman Donovan LD bodies obtained from the admitted patients only and smear-positive cases were considered as gold standard as well as confirmed cases of kala-azar.
The group of diseases known as the leishmaniases are caused by obligate intracellular protozoa of the genus Leishmania Natural transmission of leishmania is carried out by a certain species of sandfly of the genus Phlebotomus Old World or Lutzomyia New World. These are present in three different forms: The visceral form, also known as black sickness or kala-azar in Asia, is characterized by prolonged fever, splenomegaly, hepatomegaly, substantial weight loss, progressive anemia, pancytopenia, and hypergammaglobulinemia and is complicated by serious infections. It is the most severe form of the disease and, left untreated, is usually fatal. VL is typically caused by the Leishmania donovani complex, which includes three species: The clinical features of VL caused by different species are different, and each parasite has a unique epidemiological pattern.
Diagnosis of visceral leishmaniasis VL by demonstration of parasites in tissue smears obtained from bone marrow, spleen or lymph nodes is risky, painful, and difficult. The aim of the study was to evaluate the rK strip test using urine sample as a non-invasive means for the diagnosis of VL. The rk strip test was performed using urine from suspected VL cases along with 25 disease control malarial febrile cases and 50 healthy control from endemic and non-endemic areas. All the VL suspected cases were positive with the rK strip test using serum. The findings suggest that the urine based rK test could be a practical and efficient tool for the diagnosis of VL patients in rural areas, particularly where resources are limited. Diagnosis of VL still relies on clinical manifestations and microscopic confirmation of parasites from aspirates of lymph nodes, bone marrow, and the spleen. These invasive and painful techniques require skilled personnel and are difficult to implement in resource-limited settings.
