摘　　要：Aim: To evaluate the clinical significance of the quantitative determinations of endotoxins in the expressed prostatic secretions (EPS) of chronic prostatitis (CP) patients. Methods: The EPS of 45 patients with CP and 15 normal volunteers were obtained for microscopic examination, bacterial culture and endotoxin determination. The level of endotoxins was determined by the Limulus-amebocyte-lysate test with chromogenic substrate. Results: Patients with CP had higher mean levels of endotoxins in EPS than normal volunteers [52.06 ± 32.83 EU.L^(-1) vs. 4.77 ± 4.14 EU'L^(-1) (P < 0.05)]. The levels of endotoxins in CP type Ⅱ, type Ⅲa and type Ⅲb were 68.62 ± 34.78 EU.L^(-1), 45.30± 23.33 EU.L^(-1) and 15.83 ± 5.31 EU·L^(-1), respectively [type Ⅱ vs. type Ⅲa (P > 0.05), type Ⅲb vs. normal controls (P > 0.05), type Ⅱ/type Ⅲa vs. normal controls P < 0.05)]. Conclusion: CP patients have elevated levels of endotoxins in the EPS, which suggests that inflammation is a feature of this disease. EPS endotoxin determination is not only helpful in diagnostic confirmation, but also in evaluating the response to treatment in CP patients.Aim: To evaluate the clinical significance of the quantitative determinations of endotoxins in the expressed prostatic secretions (EPS) of chronic prostatitis (CP) patients.
