Abstract:
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 1α(MIP-1α),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 MIP-1α,IL-8,COX-2 levels and the dif-ferent efficacy of the two groups,clinical data of the two groups of patients,serum MIP-1α,IL-8,COX-2 levels before and after treat-ment,and to analyze the correlation of the difference of serum MIP-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-1α,IL-8,COX-2 diffe-rence and the efficacy of patients with refractory prostatitis,and to evaluate the assessment value of serum MIP-1α,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-CPSI score,maximum urinary flow rate,levels of MIP-1α,IL-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 signifi-cant(P<0.05);the difference between serum MIP-1α,IL-8 and COX-2 in patients with refractory prostatitis before and after treat-ment 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 MIP-1α,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 MIP-1α,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.
