Trace Element Levels, Cytokine Profile and Immune Activation Status in Plasma among Repeat Blood Donors with Asymptomatic HIV-1, HBV and HCV Infection
2017
Imbalance
of essential trace elements viz. Zinc, Selenium, Iron, Copper and Magnesium has been reported to influence disease course in HIV-1,
HBV and HCV infections by altering immune status. A study was taken up to
examine plasma levels of Th1 (IFN-γ and IL-2) and Th2 (IL-4 and IL-10) categories of cytokines and immune
activation markers (TNF-α, TNFR I and
TNFR II) in an asymptomatic group of HIV-1, HBV and HCV infected blood donors
in relation to trace elements. Plasma levels of Zn, Se and Mg were depressed in
all the three groups of blood donors (P γ were depressed in all the three groups
of blood donors (P γ, and in HBV infection while positive correlations were found
between Mg and TNFR I and TNFR II and Se with TNFR II. HCV infection showed a
positive correlation between Se and IFN-γ (P < 0.001), Mg and IL-4 (P = 0.02), Fe and IL-10 (P < 0.01). The present
study reveals possible relationship between trace element level alterations and
alterations in cytokine and immune activation levels in HIV-1, HBV and HCV
infection.
