Chlamydia trachomatis : probable cause of prostatitis

Abstract

Summary: Seventy-eight men with symptoms of chronic or subacute prostatitis were enrolled. Investigations for the presence of Chlamydia trachomatis in urethral swabs were carried out. The expressed prostatic secretions were additionally examined for Mycoplasma hominis , Ureaplasma urealyticum , Gardnerella vaginalis , other Gram-negative and Gram-positive bacteria, Trichomonas vaginalis , yeast-like fungi and leucocyte count. Furthermore, all patients were evaluated for the presence of serum anti-chlamydial IgG antibodies. Signs of inflammation on the basis of the count of leucocytes per hpf in the prostatic secretions were detected in 42 patients (group I). Prostatodynia was found in the remaining 36 men (group II). In group I, chlamydial antigen was detected in the urethra and expressed prostatic secretions (EPS) in 6 (14.3%) and 9 (21.4%) patients, respectively. No evidence of current chlamydial infection was found in group II. The presence of serum anti-chlamydial IgG antibodies was demonstrated in 13/42 (30.9%) patients with prostatitis and in 3/36 (8.3%) patients with prostatodynia ( P 0.01). The results suggest that chlamydia may be one of the causative agents of chronic prostatitis. <
