[Immunoglobulins in the serum of chronic pyelonephritis patients].

The authors studied the serum levels of immunoglobulins G, A and M in 72 patients with chronic pyelonephritis and 77 clinically healthy subjects. In spite of the high biological variability of the indices studied, high serum levels of IgG and IgA were established in the patients with active urologic infection and with advanced renal insufficiency. Significantly higher values of IgG were established in active pyelonephritis, caused by E. coli and Proteus and of all immunoglobulins--in infection with Enterococcus. The serum level of immunoglobulins in chronic pyelonephritis should be complexly interpreted, together with the other clinical and laboratory data.
