[Urinary and serum o-antibodies in patients with chronic pyelonephritis (author's transl)]
Urine (24-hour-specimen, 100-fold concentrated) and serum samples from adults with chronic pyelonephritis have been investigated for O antibody against the strain isolated from the urine by means of the indirect hemagglutination and indirect immunofluorescence technique. Using the hemagglutination technique about one third of the urine showed the presence of O antibody. The highest titer demonstrated was 1:16. O antibody determined by the immunofluorescence technique could be demonstrated in 54.9% of the urine samples. Titers up to 1:256 were found. Serum O antibody corresponded to those found in adults with chronic pyelonephritis. In general there was no correlation between urine and serum O antibody. The diagnostic and prognostic value of the results is discussed.
