Abstract

Opinion among researchers is divided as to whether Chlamydia trachomatis is the causative organism of chronic prostatitis. In this study, using enzyme immuno assay, we examined the positive rate of anti-C. trachomatis IgA according to the leukocyte count in expressed prostate secretion (EPS), in a total of 169 patients including 92 patients who showed chronic prostatitis-like symptoms. And we confirmed, by western-blotting, the presence or absence of anti-heat shock protein (HSP: 60 KDa) IgA in EPS, and we investigated the role of C. trachomatis in chronic prostatitis. The total positive rate of anti-C. trachomatis IgA in EPS was 26.0% (44/169). According to the leukocyte count in EPS, the positive rate for the group with more than 10 WBC/hpf was 29.0% (20/69), for the group with 5-9 WBC/hpf was 37.9% (11/29), for the group with less than 5 WBC/hpf was 18.3% (13/71). Accordingly the positive rate of anti-C. trachomatis IgA in EPS was not higher in direct correlation to the severity of the inflammation at the infected site (p = 0.09). But the positive rate for the group with more than 5 WBC/hpf was higher than for the group with less than 5 WBC/hpf. On the other hand, the total positive rate of anti-HSP IgA in EPS was 17.6% (6/34), and according to the leukocyte count in EPS, the positive rate for the group with more than 10 WBC/hpf was 38.5% (5/13), for the group with 5-9 WBC/hpf was 0% (0/12). Accordingly the positive rate of anti-HSP IgA in EPS was higher in direct correlation to the severity of the inflammation at the infected site (p = 0.13). From this results, it was suggested that C. trachomatis was concerned with 29.0% (20/69) of chronic prostatitis with more than 10 WBC/hpf, and also C. trachomatis is the causative organism of chronic prostatis.
