Introduction. Chronic recurrent bacterial prostatitis (HRBP) affects the reproductive function and negatively affects the quality of life of men. The multifactorial pathogenesis of this disease causes the failure of antibiotic therapy and some cases, requires an in-depth study of the mechanisms of disease development and additional treatment methods.
Objectives of the study: to study of the effectiveness of immunoactive therapy (recombinant interferon alpha-2b with an antioxidant complex) in combination with antibacterial therapy in patients
with HRBP.
Materials and Methods. Prospective trial: examination and treatment of 62 patients. Two groups: I (study) group (n=31) received antibacterial therapy (ABT) and a therapy with recombinant IFN Alpha-2b based medication with antioxidant complex (vitamins E and C), II (control) group (n=31) received only ABT.
The examination plan included questionnaires (NIH – CPSI, IPSS, Hamilton), general blood and urine tests, biochemical blood tests, urethral scrapings for PCR diagnostics, plasma testosterone, native, electron microscopy, culture test and immunoferment analysis of the prostate sercet, uroflowmetry, Transrectal ultrasonography (TRUS).
Results. When monitoring the clinical picture according to questionnaires (IPSS, NIH-CPSI, Hamilton scale) and laboratory indicators, 1 month after treatment, a significant reduction in symptoms was observed in both groups, and after 3, 6, and 12 months – in patients of group I.
Conclusions. The Combination of an antibacterial drug and recombinant interferon alpha-2b in the treatment of HRBP provides more effective relief of the infectious and inflammatory process in the long term than antibacterial monotherapy
