چکیده
Leishmania donovani in India causes visceral infection (kala-azar) and dermal infection (post-kala-azar dermal leishmaniasis). We report here the identification of polymorphism in a well-defined genetic locus among the Leishmania parasites causing the visceral and dermal manifestations, in a comparison of 15 post-kala-azar dermal leishmaniasis and 12 kala-azar patient isolates.

the patient had visceral leishmaniasis (kala-azar), successfully treated with 30 intramuscular injections of sodium stibogluconate (SSG). Polymerase chain reaction showed Leishmania donovani DNA in a buffy coat specimen. Post-kala-azar dermal leishmaniasis (PKDL) is a chronic skin rash usually seen in apparently cured kala-azar patients in East Africa and South Asia. In the Indian subcontinent,...
متن کاملNested PCR assay for detection of Leishmania donovani in slit aspirates from post-kala-azar dermal Leishmaniasis Lesions.
A nested PCR assay to detect parasite DNA in slit aspirates from skin lesions of patients with post-kala-azar dermal lesihmaniasis (PKDL) is described. PCR results were positive in 27 of 29 (93%) samples by nested PCR assay, while only 20 of 29 (69%) were positive in a primary PCR assay. The nested PCR assay allowed reliable diagnosis of PKDL in a noninvasive manner.

متن کاملA Case of Post-Kala-Azar Dermal Leishmaniasis
Only a few cases of Post-kala-azar dermal leishmaniasis have been reported in Japan, especially recently. We describe a case of a 32-year-old woman who developed rose-colored nodules on her forearms two years after Kala-azar. A skin biopsy specimen from a nodule revealed not only granulomatous changes but also many amastigotes of Leishmania donovani in macrophages. Rose-colored nodules were als...

Post-kala-azar dermal leishmaniasis (PKDL) is a dermatologic manifestation that usually occurs after visceral leishmaniasis (VL) caused by Leishmania donovani. It is characterized by hypopigmented patches, a macular or maculopapular rash and nodular skin lesions on the body surface. Involvement of the mucosae is very rare and unusual in PKDL. We report a case of PKDL that presented with polymor...
