[Modification by cyclophosphamide of the effect of autovaccination in chronic pyelonephritis in an animal experiment].

In an existing chronic pyelonephritis the influence of cyclophosphamide on the efficacy of an immunisation with autopathogenic antigens and the surface antigen of an E. coli rough strain was tested in an animal experiment. After an existence of the infection of about five weeks a decisive decrease of the antibody production by cyclophosphamide was not to be observed. The animals treated with cyclophosphamide did not show any improved elimination of germs. The histological findings of the kidneys documented the cytotoxical effect of the cyclophosphamide on the renal tissues and the epithelium of the urinary tract. The immunisation of animals with chronic pyelonephritis with various autopathogenic antigens altogether led to a statistically significant decrease of inflammatorily changed kidneys.
