Objective: To investigate the characteristics of infectious pathogens in patients with refractory prostatitis, and to detect serum levels of factors related to immune inflammatory response such as macrophage inflammatory protein la (MlP-la), IL-8 and cyclooxygenase-2 (COX-2). Methods: A total of 87 patients with refractory chronic prostatitis who were diagnosed and treated in the Outpatient Department of Zhengzhou Ninth People's Hospital and Andrology Outpatient Department of Zhengzhou Central Hospital from October 2018 to June 2020 were selected as observation group, and 87 healthy subjects were selected as control group. Analyzed characteristics of infectious pathogens in patients with refractory prostatitis, compared serum MlP-la, IL-8, COX-2 levels and the different efficacy of the two groups, clinical data of the two groups of patients, serum MIP-1α, IL-8, COX-2 levels before and after treatment, and to analyze the correlation of the difference of serum MlP-1α, IL-8, COX-2 and the duration of the disease, the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI), maximum urinary flow rate and the relationship between serum MIP- la, IL-8, COX-2 diffe-rence and the efficacy of patients with refractory prostatitis, and to evaluate the assessment value of serum MlP-la, IL-8, COX-2 difference on the efficacy of patients with refractory prostatitis. Results: Bacterial infection was present in 87 specimens of prostatic fluid from patients with refractory prostatitis, and 9 patients had concomitant mycoplasma infection. From the prostatic fluid samples of 87 patients with refractory prostatitis, a total of 338 pathogenic bacteria were isolated, including 230 gram- positive bacteria, accounting for 68.05%; 108 gram-negative bacteria, accounting for 31.95%; serum MIP-1α, IL-8, COX-2 levels in observation group were higher than that in control group, the difference was statistically significant (P<0.05) ; the course of disease, NIH-CPS1 score, maximum urinary flow rate, levels of MIP-1α, 1L-8, COX-2 after treatment, and the difference of MIP-1α, IL-8, COX-2 before and after treatment were compared in patients with different curative effects, and the difference was statistically significant (P<0.05) ; the difference between serum MIP-1α, IL-8 and COX-2 in patients with refractory prostatitis before and after treatment was positively correlated with disease course and NIH-CPSI score, while negatively correlated with maximum urinary flow rate (P<0.05) ; the differences of serum MlP-lot, IL-8 and COX-2 before and after treatment were significantly correlated with curative effect of patients with refractory prostatitis (P<0.05) ; AUC values of serum MlP-l1α IL-8 and COX-2 before and after treatment to evaluate the efficacy of refractory prostatitis patients were 0.856, 0.819 and 0.788, respectively, and the combined AUC value was the largest, which was 0.903. Conclusion: Pathogenic bacteria in patients with refractory prostatitis are mainly gram-positive bacteria, and the serum MIP-1α, IL-8 and COX-2 are significantly increased, which are closely related to the evolution of the disease. They can be used to evaluate clinical efficacy, and provide information for subsequent treatment. [ABSTRACT FROM AUTHOR] |
