Liver morphology and function in visceral leishmaniasis (Kala-azar).

Aim: To study the morphology and function of the liver in visceral leishmaniasis (Kala-azar).

Methods: Percutaneous liver biopsy specimens from 18 patients with confirmed visceral leishmaniasis were examined under light and electron microscopy before and after treatment with pentovalent antimony. The tissue was also examined for hepatitis B surface and core antigens using immunoperoxidase staining.

The treatment of kala-azar in the Sudan with sodium stibogluconate: a randomized trial of three dosage regimens.

In a randomized study in the Sudan, 3 different regimens of sodium stibogluconate were compared in patients with parasitologically confirmed kala-azar (visceral leishmaniasis): 10 mg/kg for 30 d (38 patients), 20 mg/kg for 30 d (29 patients), and 20 mg/kg for 15 d (37 patients). Treatment failures were defined as death, partial response, relapse, or the development of post-kala-azar dermal leishmaniasis. The hazard ratio for failure of 20 mg/kg for 30 d vs.

Kala-azar: a comparative study of parasitological methods and the direct agglutination test in diagnosis.

In a comparative study 88 patients were diagnosed as suffering from kala-azar (visceral leishmaniasis) using 3 parasitological methods simultaneously. Splenomegaly was absent in 4 cases. In 84 patients with splenomegaly, splenic aspiration appeared to be the most sensitive method (96.

Oral leishmaniasis associated with kala-azar. A case report.

Mucosal leishmaniasis as an oral disease in the form of chronic periodontitis with involvement of the oral mucosa is described. Leishmania parasites were isolated from the oral lesions, lymph nodes, and bone marrow. The patient had a low-grade fever and hepatosplenomegaly that regressed along with the oral lesions after treatment with stibogluconate sodium.
