[The immune status of patients with primary and secondary chronic pyelonephritis].

Immunological examination (T- and B-cell immunity, metabolic activity of phagocytes) was conducted in 10 patients with primary and 21 patients with secondary chronic pyelonephritis in the phase of latent inflammation resistant to conventional antibacterial therapy versus 12 patients free of this disease. It was found that immunoreactivity in the above patients was compromised as shown by quantitative and qualitative deficiency of T-cell immunity (a fall in the absolute number of CD3+, absolute and relative content of CD2+DR+, changed proportion of T-lymphocyte subpopulations, low activity of oxygen-dependent anti-infection systems of phagocytes). B-system immunity did not much change for the worse. In primary chronic pyelonephritis immunoreactivity was affected more seriously.
