title: [Once more about interstitial nephritis].
abstract: A comparative study was made of 25 patients (Group 2, control) with documented pyelonephritis and 55 patients (Group 1) who had a morphological picture of chronic interstitial inflammation without signs of abnormal urodynamics, bacteriuria, urographic and sonographic evidence of pyelonephritis. All the patients underwent life-time morphological study, their immunological spectrum (IgA, IgG, IgM, IgE) was explored. They had a test for sensitization of a peripheral blood mononuclear fraction to one or several drugs which had been given to the patients. The patients from Group 1 displayed significantly elevated IgE levels and a regularly detected sensitization of mononuclears to one or several drugs. Morphologically, there were signs of congenital renal tissue dysplasia in the presence of diffuse interstitial inflammation. Positive immunofluorescence findings were seen in the tubular wall of 10 (18%) patients. The findings made it possible to define diagnostic criteria for interstitial nephritis, a nosological entity.
