Abstract
Zinc deficiency has been recently reported in AIDS patients to be associated with a decrease in T helper cells. The effect of zinc supplementation was evaluated in 5 ARC patients and 5 control subjects using lymphocyte subset counts, blast transformation and chemiluminescence of polymorphonuclear leukocytes. Zinc was analysed by atomic absorption spectrophotometry. T-cell subsets were quantified by cytofluorometry. Chemiluminescence of PMN was measured by phagocytosis of opsonized zymosan. The ARC patients had significantly lower zinc concentrations in the RBC prior to supplementation (p < 0.05). This level increased following the administration of zinc gluconate. This increase was accompanied by (i) an increase in HLA.Dr + cells with no CD4 CD8 ratio alteration; (ii) a stimulation of lymphocyte transformation and PMN chemiluminescence particularly after 15 days' high zinc supplementation. Such a reconstitution in specific and non specific immune functions in ARC patients may warrant further investigation.
