During an epidemiological study of visceral leishmaniasis (VL) in south-west Ethiopia, 33 VL patients, 9 treated VL patients, 14 individuals with sub-clinical infection, 34 individuals with asymptomatic infection, and 19 healthy controls were studied for T cell subsets and cytokine profiles. Negative leishmanin skin test, CD3 and CD4 lymphocytopenia, and significantly reduced numbers of memory CD4(+) T cells were found in VL patients compared to treated VL patients or persons with self-limiting asymptomatic infection. The proportion of CD4(+) and CD8(+) T cells that produced IFN-gamma and IL-4 after stimulation with PMA (Phorbol 12-myristate 13-acetate) and ionomycin was significantly reduced in VL patients compared to sub-clinical and asymptomatic infections or healthy controls. Plasma concentrations of IFN-gamma and IL-10 were elevated in VL. (c) 2005 Elsevier Inc. All rights reserved.
