[Selected markers of cell-mediated and humoral immunity in children with chronic pyelonephritis].

The studied group comprised 38 boys and girls aged from 7 months to 5 years with chronic pyelonephritis. Counts of B and T-cells and serum concentrations of IgG, IgM, IgA were determined. A significant depression was noted of the per cent proportion of T-cells in relation to the control group of healthy children with a significantly lower IgM concentration without significant changes in IgG and IgA levels.
