[Search for homologous antibodies during urinary infections in patients with or without renal allografts (author's transl)].
We studied the immune response during urinary infections, firstly in 20 patients with a renal allograft and receiving immunosuppressive agents, secondly in 55 patients consulting on a renal unit. Homologous antibodies were sought in the urine (test for antibodies fixed on urinary bacteria AFBU) and in the serum (seroagglutination, indirect immunofluorescence) using an antigens strains isolated from patients' urine. Comparative statistical analysis of the results given by the 3 methods reveals a good correlation between these tests in non-transplanted patients. On the other hand, there is no statistical link between seroagglutination and the AFBU test in transplanted patients, whereas the results of indirect immunofluorescence and the AFBU test remain strongly correlated. The interest of the 3 methods is discussed.
