Serum chemokine profiles in visceral leishmaniasis, HIV and HIV/ visceral leishmaniasis co-infected Ethiopian patients (original) (raw)

Ethiopian medical journal, 2011

Abstract

The search for a correlation between chemokine levels in plasma or serum and protection from HIV infection or progression to AIDS has been attempted by a number of workers. Chemokines are also suggested to play a role in immunity to Leishmania and Leishmania co-infection with HIV. To assess plasma level of alpha chemokine (CXCL12, formerly known as SDF-1alpha) and beta chemokines (CCL3, CCL4 and CCL5, formerly known as MIP-1alpha, MIP-1beta and RANTES, respectively) in HIV Visceral Leishmaniasis (VL) and HIV/VL coinfection. Frozen serum samples from a cross sectional study were used. The samples (n = 80) were comprised of healthy controls (n = 20), HIV patients (n = 20); Visceral Leishmaniasis (VL) patients (n = 22), and HIV/VL coinfected patients (n = 18). Chemokine levels of MIP-1alpha, MIP-1beta, RANTES, and SDF-1alpha of the serum samples were determined using ELISA. MIP-1alpha and MIP-1beta expression were significantly elevated in Leishmania infected (p < 0.001) and in HIV/...
