Evaluation by immunofluorescence of the urinary bacteria, of the therapy effectiveness in urinary infections

Abstract

The therapy effectiveness in urinary infections (UI) was investigated in 27 patients by the test of immunofluorescence of the urinary bacteria (IFUB) in relationship with bacteriuria, various other biologic investigations and tests of the immune response. The study revealed a complex involvement of the immune mechanisms in the UI occurrence and persistence, as well as a parallelism between the mechanisms of cellular and humoral immunity in some of the patients. The IFUB test could reveal the eventual germ persistence at the renal parenchyma level even in the absence of significant bacteriuria, thus suggesting the necessity of a long term suppressive therapy in such cases.
