[Incidence of antibody-coated bacteria in patients with chronic pyelonephritis].

Of 168 urine sediments, which were obtained from 55 patients with chronic pyelonephritis in the course of 3 years when a significant bacteriuria with E. coli was present, we demonstrated antibody-loaded bacteria in 81 cases (48.21%). In the active stage of the disease with 54.10% were found significantly more than in the inactive with 32.61%. In obstructive chronic pyelonephritis the positive rate was 54.79% in contrast to 43.16% in non-obstructive chronic pyelonephritis. While in the active stage of the obstructive chronic pyelonephritis with 57.41% more antibody-containing bacteria were excreted than with 47.31% in the inactive stage, the positive rate in the active stage of the non-obstructive chronic pyelonephritis was with 54.47% significantly increased in contrast to 22.22% in the inactive stage. 25.71% of the patients excreted only ACB+-, 34.29% only ACB(-)- and 40% ACB+- and ACB(-)-germs in the course of the disease. The ACB-positive quote was in rough forms with 62.50% statistically significantly increased in contrast to 45.54% in O-typable and 42.86% in non-O-typable strains. In the ACB+- group the immunofluorescence titres to the homologous strain and the C3-activator in the serum as well as the urine lysozyme were significantly higher than in the ACB(-)-group.
