This information provides a new vision that pathogens could play a role through the redundant prepuce; numerous studies have failed to find pathogens in prostates of patients who had chronic prostatitis/chronic pelvic pain syndrome （CP/CPPS）. However, no studies have reported an association between foreskin length and CP/CPPS. Hence, we conducted a retrospective case-control study of clinical data from 322 CP/CPPS patients （case group） and 341 nonCP/CPPS patients （control group）. Demographic characteristics, lifestyle factors, and foreskin lengths were collected and analyzed. Multivariate logistic regression was adopted to calculate the odds of foreskin length for CP/CPPS. According to the multivariate logistic regression results, when the foreskin length covered up more than half of the glans penis, the odds for CP/CPPS were higher with an increased foreskin （odds ratio （OR）： 1.66, 95% confidence interval （CI）： 1.04-2.66）. In comparison, when the glans penis was completely covered by the foreskin, the OR value increased to 1.86 （95% CI, 1.2-2.88）. The study results showed an association between foreskin length and the odds of CP/CPPS. When the foreskin length covered up more than half of the glans penis, there were greater odds for CP/CPPS. This possible mechanism might result from interaction between pathogens and DCs in the inner foreskin, consequently activating T-cells to mediate allergic inflammation in the prostate and producing the autoimmunizations causing CP/CPPS.展开更多

EPSs were collected from the subjects, which included 26 normal men, 11 infertile patients and 51 CP/CPPS patients. DNA was extracted from each specimen, and the V3 regions of the 16S rRNA genes were amplified using universal bacterial primers. The results showed that the EPS 16S rRNA gene-positive rate in the CP/CPPS and infertile patients was much higher than in the normal men, but without any difference among the three patient groups. The denaturing gradient gel electrophoresis （DGGE） method was used to characterize the EPS bacterial community structure of the prostate fluid from patients with CP/CPPS or infertility issues. Principal component analysis （PCA） and partial least squares （PLS） analyses of PCR-DGGE profiles revealed that the EPS bacterial community structure differed among the three groups. Three bands were identified as the key factors responsible for the discrepancy between CP/CPPS patients and infertile patients （P〈O.05）. Two bands were identified as priority factors in the discrepancy of category IliA and category IIIB prostatitis patients （P〈O.05）. According to this research, the ecological balance of the prostate and low urethra tract, when considered as a microenvironment, might play an important role in the maintenance of a healthy male reproductive tract.展开更多

CP/CPPS has been a cause of great concern for both patients and physicians because of the lack of presence of thoroughinformation about the etiological factors along with the difficult-to-treat nature of the syndrome. For the presented manuscript an extensive search on PubM ed was conducted for CP/CPPS aimed to present an updated review on the evaluation and treatment options available for patients with CP/CPPS. Several diagnostic criteria's have been established to diagnose CP/CPPS, with prostatic/pelvic pain for at least 3 mo being the major classifying symptom along with the presence of lower urinary tract symptoms and/or ejaculatory pain. Diagnostic tests can help differentiate CP/CPPS from other syndromes that come under the heading of prostatitis by ruling out active urinary tract infection and/or prostatic infection with uropathogen by performing urine cultures, Meares-Stamey Four Glass Test, Preand Post-Massage Two Glass Test. Asymptomatic inflammatory prostatitis is confirmed through prostate biopsy done for elevated serum prostate-specific antigen levels or abnormal digital rectal examination. Researchers have been unable to link a single etiological factor to the pathogenesis of CP/CPPS, instead a cluster of potential etiologies including atypical bacterial or nanobacterial infection, autoimmunity, neurological dysfunction and pelvic floor muscle dysfunction are most commonly implicated. Initially monotherapy with anti-biotics and alpha adrenergic-blockers can be tried, but its success has only been observed in treatment nave population. Other pharmacotherapies including phytotherapy, neuromodulatory drugs and anti-inflammatories achieved limited success in trials. Complementary and interventional therapies including acupuncture, myofascial trigger point release and pelvic floor biofeedback have been employed. This review points towards the fact that treatment should be tailored individually for patients based on their symptoms. Patients can be stratified phenotypically based on the UPOINT system constituting of Urinary, Psychosocial, Organ-specific, Infectious, Neurologic/Systemic and symptoms of muscular Tenderness and the treatment algorithm should be proposed accordingly. Treatment of CP/CPPS should be aimed towards treating local aswell as central factors causing the symptoms. Surgical intervention can cause significant morbidity and should only be reserved for treatment-refractory patients that have previously failed to respond to multiple drug therapies.展开更多

Methods: From November 2001 to April 2002, patients visiting the Urological Outpatient Clinic of this Hospital were evaluated by means of the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) and classified by the NIH classification standard. Sixty-two patients of CPPS category Ⅲwere involved in this study. All patients had been treated by conventional approaches such as antibiotics and alpha-blockers for more than half a year without any improvement. The expressed prostatic secretion results were as follows: WBC 5 to 9/high power field, lipid +-+++and bacterial culture negative. Their NIH-CPSI were 12-40. All the 62 cases complained of micturitional irritation (frequency, urgency, splitted stream and sense of residual urine), 32 cases, of pain or discomfort at the testicular, penile, scrotal, pelvic or rectal region and 13 cases, of white secretion-dripping. The patients were treated by the Urostym Biofeedback equipment (Laborie Co., Canada) 5 times a week for 2 weeks with a stimulus intensity of 15 mA-23 mA and duration of 20 minutes. Results: Sixty patients were significantly improved or cured, while no significant improvement in the remaining 2. No apparent side effect was observed. The NIH-CPSI dropped to 6 to 14 with an average reduction of 21 (P<0.01). In the 60 improved cases, pain was relieved after 2-3 treatment courses and other symptoms disappeared after 4-5 courses. Conclusion: Biofeedback therapy is a safe and effective treatment for CPPS. Large randomized clinical trials are needed to confirm its efficacy and to explore the mechanism of action.展开更多

The aim of this study is to retrospectively compare the microbiological and clinical findings of two treatment schemes for CBP based on the combination of azithromycin （500 rag, thrice-weekly） with a once-daily 500- or 750-mg dose of ciprofloxacin （Cipro-500 or Cipro-750 cohort, respectively）. Combined administration of azithromycin （1500 mg week^-1） with ciprofloxacin at the rate of 750 mg day^- 1 for 4 weeks rather than at 500 mg day^- 1 for 6 weeks increased the eradication rates from 62.35% to 77.32% and the total bacteriological success from 71.76% to 85.57%. A significant decrease in pain and voiding signs/symptoms and a significant reduction in inflammatory leukocyte counts and serum prostate-specific antigen （PSA） were sustained throughout an 18-month follow-up period in both groups. Ejaculatory pain, haemospermia and premature ejaculation were significantly attenuated on microbiological eradication in both groups, but the latter subsided more promptly in the Cipro-750 cohort. In total, 59 Cipro-750 patients showed mild-to-severe erectile dysfunction （ED） at baseline, while 22 patients had no ED on microbiological eradication and throughout the follow-up period. In conclusion fluoroquinolone-macrolide therapy resulted in pathogen eradication and CBP symptom attenuation, including pain, voiding disturbances and sexual dysfunction. A once-daily 750-mg dose of ciprofloxacin for 4 weeks showed enhanced eradication rates and lower inflammatory white blood cell counts compared to the 500-mg dose for 6 weeks. Our results are open to further prospective validation.展开更多

Methods： A random sample of 850 Korean urologists from the Korean Urological Association Registry of Physicians were asked to complete a questionnaire that explored practicing characteristics, attitudes and diagnostic and treatment strategies in the management of chronic prostatitis. Results： Of the 850 questionnaires sent, 302 were returned （response rate 35.5 %） and 275 were induced in the final analysis. More than 50 % believed in a multifactorial etiology for chronic prostatitis and 52 % considered chronic abacterial prostatitis to be bacterial in nature. For routine diagnostic assessment, the most commonly used tests were reported to be urinalysis （95.3 %）, analysis of expressed prostatic secretions （89.5 %） and digital rectal examination （81.1%）. Only a few urologists use specific lower urinary tract cultures. Symptom assessment according to the National Institute of Health-Chronic Prostatitis Symptom Index was less frequently used （12.7 %）. First choices for therapy included antibiotics （96.4 %）, alpha-blockers （71.6 %） and sitz baths （70.5 %）. If unsuccessful, urologists frequently continued to prescribe a second course of either alpha-blockers （69.5 %） or antibiotics （57.8 %）. Conclusion： These data provide a picture of current practice regarding the management of chronic prostatitis in Korea. The diagnostic and treatment practices for prostatitis do not follow standard textbook algorithms. Further studies are needed to elucidate the etiology and pathogenesis of chronic prostatitis and to establish guidelines for its diagnosis and treatment.展开更多

To investigate the diagnostic relevance of semen culture in the bacteriological workup of prostatitis patients, we retrospectively analyzed a clinical database of 696 symptomatic patients. All patients were routinely subjected to a four-glass test, followed by semen culture and analysis. This allowed to dissect from the database three different diagnostic scenarios, and to compare the ＇two-glass＇ pre-/post- massage test and the standard ＇four-glass＇ test with a ＇five-glass＇ test （four-glass plus post-VB3 semen culture）. The ＇five-glass＇ test showed 3.6- or 6.5-fold increases in relative sensitivity and lesser reductions （-13.2% or -14.7%） in relative specificity for traditional uropathogens （TUs） compared with the four-glass or two-glass test, respectively. The area under the ROC curve and Jouden＇s index were increased, whereas positive and negative likelihood ratios were lower than comparators, indicating that the ＇five-glass＇ assay may be superior in confirming the negative outcome of both standard tests. The five-, four-, and two-glass tests detected TUs （Enterobacteriaceae, Enterococci, etc.） in 120, 33, and 20 patients and unusual pathogens （Streptococci, other Gram-positive species, Mycoplasmata, and others） in 130, 56, and 45 patients, respectively. When patients were subjected to pharmacological treatment, including a combination of a fluoroquinolone and a macrolide, no differences in eradication rates were observed between groups diagnosed with different tests, irrespective of pathogen category. Eradication was associated with long-term sign/symptom remission; no significant intergroup differences in sign/symptom scores were observed throughout a 24-month off-therapy follow-up period. In conclusion, our data support the usefulness of semen analysis in the diagnostic workup ofprostatitis patients when this test is used to complement the four-glass Meares and Stamey test. Improvement of microbiological assays conveys important diagnostic and therapeutic implications.展开更多

文摘Objective:To assess the efficacy and safety of a treatment regimen based on rectal administration of Boswellia resin extract and propolis derived polyphenols in patients with type IIIa and type IIIb chronic prostatitis and chronic pelvic pain syndrome(CP/CPPS).Methods:Patients with type IIIa and type IIIb CP/CPPS received one rectal suppository a day for 15 days per month for 3 consecutive months.Participants were evaluated with National Institutes of Health-Chronic Prostatitis Symptom Index(NIH-CPSI),the International Prostate Symptom Scores(IPSS),International Index of Erectile Function(IIEF),four-glass test,uroflowmetry,and prostate-specific antigen assessments at baseline and at Week 4,and Week 12.Primary endpoints were improvement in pain domain of NIH-CPSI and improvement of NIH-CPSI total score.Secondary outcomes included improvement of micturition and quality of life(QoL)domains of NIH-CPSI questionnaire.Results:A total of 61 males were enrolled.No adverse events were reported.Significant improvements from baseline to Day 30 were reported for NIH-CPSI total score(mean difference:-9.2;p<0.01),NIH-CPSI pain domain(mean difference:-5.5;p<0.01),NIH-CPSI micturition domain,NIH-CPSI QoL domain,and IPSS total score(mean difference:-5.6;p<0.01).No significant changes from baseline in terms of IIEF score or maximum flow rate were observed.At final follow-up(Day 90),further significant improvements in terms of NIH-CPSI total score(mean difference:-12.2;p<0.01),NIH-CPSI pain domain(mean difference:-6.6;p<0.01),NIH-CPSI micturition domain,NIH-CPSI QoL domain,and IPSS total score were reported.Conclusion:Rectal administration of Boswellia resin extract and propolis derived polyphenols is well tolerated and delivers a significant symptomatic improvement in most patients with type IIIa and type IIIb CP/CPPS.
文摘Prostatitis comprises of a group of syndromes that affect almost 50% of men at least once in their lifetime and makeup the majority of visits to the Urology Clinics.After much debate, it has been divided into four distinct categories by National Institutes of Health namely(1) acute bacterial prostatitis;(2) chronic bacterial prostatitis;(3) chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS) which is further divided into inflammatory and non-inflammatory CP/CPPS; and(4)asymptomatic inflammatory prostatitis. CP/CPPS has been a cause of great concern for both patients and physicians because of the lack of presence of thoroughinformation about the etiological factors along with the difficult-to-treat nature of the syndrome. For the presented manuscript an extensive search on PubM ed was conducted for CP/CPPS aimed to present an updated review on the evaluation and treatment options available for patients with CP/CPPS. Several diagnostic criteria's have been established to diagnose CP/CPPS, with prostatic/pelvic pain for at least 3 mo being the major classifying symptom along with the presence of lower urinary tract symptoms and/or ejaculatory pain. Diagnostic tests can help differentiate CP/CPPS from other syndromes that come under the heading of prostatitis by ruling out active urinary tract infection and/or prostatic infection with uropathogen by performing urine cultures, Meares-Stamey Four Glass Test, Preand Post-Massage Two Glass Test. Asymptomatic inflammatory prostatitis is confirmed through prostate biopsy done for elevated serum prostate-specific antigen levels or abnormal digital rectal examination. Researchers have been unable to link a single etiological factor to the pathogenesis of CP/CPPS, instead a cluster of potential etiologies including atypical bacterial or nanobacterial infection, autoimmunity, neurological dysfunction and pelvic floor muscle dysfunction are most commonly implicated. Initially monotherapy with anti-biotics and alpha adrenergic-blockers can be tried, but its success has only been observed in treatment nave population. Other pharmacotherapies including phytotherapy, neuromodulatory drugs and anti-inflammatories achieved limited success in trials. Complementary and interventional therapies including acupuncture, myofascial trigger point release and pelvic floor biofeedback have been employed. This review points towards the fact that treatment should be tailored individually for patients based on their symptoms. Patients can be stratified phenotypically based on the UPOINT system constituting of Urinary, Psychosocial, Organ-specific, Infectious, Neurologic/Systemic and symptoms of muscular Tenderness and the treatment algorithm should be proposed accordingly. Treatment of CP/CPPS should be aimed towards treating local aswell as central factors causing the symptoms. Surgical intervention can cause significant morbidity and should only be reserved for treatment-refractory patients that have previously failed to respond to multiple drug therapies.
文摘<abstract>Aim: To evaluate the efficacy of biofeedback therapy in patients with chronic pelvic pain syndrome (CPPS). Methods: From November 2001 to April 2002, patients visiting the Urological Outpatient Clinic of this Hospital were evaluated by means of the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) and classified by the NIH classification standard. Sixty-two patients of CPPS category Ⅲwere involved in this study. All patients had been treated by conventional approaches such as antibiotics and alpha-blockers for more than half a year without any improvement. The expressed prostatic secretion results were as follows: WBC 5 to 9/high power field, lipid +-+++and bacterial culture negative. Their NIH-CPSI were 12-40. All the 62 cases complained of micturitional irritation (frequency, urgency, splitted stream and sense of residual urine), 32 cases, of pain or discomfort at the testicular, penile, scrotal, pelvic or rectal region and 13 cases, of white secretion-dripping. The patients were treated by the Urostym Biofeedback equipment (Laborie Co., Canada) 5 times a week for 2 weeks with a stimulus intensity of 15 mA-23 mA and duration of 20 minutes. Results: Sixty patients were significantly improved or cured, while no significant improvement in the remaining 2. No apparent side effect was observed. The NIH-CPSI dropped to 6 to 14 with an average reduction of 21 (P<0.01). In the 60 improved cases, pain was relieved after 2-3 treatment courses and other symptoms disappeared after 4-5 courses. Conclusion: Biofeedback therapy is a safe and effective treatment for CPPS. Large randomized clinical trials are needed to confirm its efficacy and to explore the mechanism of action.
文摘We previously demonstrated the safety and efficacy of fluoroquinolone-macrolide combination therapy in category Ⅱ chronic bacterial prostatitis （CBP）. The aim of this study is to retrospectively compare the microbiological and clinical findings of two treatment schemes for CBP based on the combination of azithromycin （500 rag, thrice-weekly） with a once-daily 500- or 750-mg dose of ciprofloxacin （Cipro-500 or Cipro-750 cohort, respectively）. Combined administration of azithromycin （1500 mg week^-1） with ciprofloxacin at the rate of 750 mg day^- 1 for 4 weeks rather than at 500 mg day^- 1 for 6 weeks increased the eradication rates from 62.35% to 77.32% and the total bacteriological success from 71.76% to 85.57%. A significant decrease in pain and voiding signs/symptoms and a significant reduction in inflammatory leukocyte counts and serum prostate-specific antigen （PSA） were sustained throughout an 18-month follow-up period in both groups. Ejaculatory pain, haemospermia and premature ejaculation were significantly attenuated on microbiological eradication in both groups, but the latter subsided more promptly in the Cipro-750 cohort. In total, 59 Cipro-750 patients showed mild-to-severe erectile dysfunction （ED） at baseline, while 22 patients had no ED on microbiological eradication and throughout the follow-up period. In conclusion fluoroquinolone-macrolide therapy resulted in pathogen eradication and CBP symptom attenuation, including pain, voiding disturbances and sexual dysfunction. A once-daily 750-mg dose of ciprofloxacin for 4 weeks showed enhanced eradication rates and lower inflammatory white blood cell counts compared to the 500-mg dose for 6 weeks. Our results are open to further prospective validation.
文摘Aim： To examine the diagnosis and treatment of chronic prostatitis by means of a nationwide postal survey of practicing urologists in 2004. Methods： A random sample of 850 Korean urologists from the Korean Urological Association Registry of Physicians were asked to complete a questionnaire that explored practicing characteristics, attitudes and diagnostic and treatment strategies in the management of chronic prostatitis. Results： Of the 850 questionnaires sent, 302 were returned （response rate 35.5 %） and 275 were induced in the final analysis. More than 50 % believed in a multifactorial etiology for chronic prostatitis and 52 % considered chronic abacterial prostatitis to be bacterial in nature. For routine diagnostic assessment, the most commonly used tests were reported to be urinalysis （95.3 %）, analysis of expressed prostatic secretions （89.5 %） and digital rectal examination （81.1%）. Only a few urologists use specific lower urinary tract cultures. Symptom assessment according to the National Institute of Health-Chronic Prostatitis Symptom Index was less frequently used （12.7 %）. First choices for therapy included antibiotics （96.4 %）, alpha-blockers （71.6 %） and sitz baths （70.5 %）. If unsuccessful, urologists frequently continued to prescribe a second course of either alpha-blockers （69.5 %） or antibiotics （57.8 %）. Conclusion： These data provide a picture of current practice regarding the management of chronic prostatitis in Korea. The diagnostic and treatment practices for prostatitis do not follow standard textbook algorithms. Further studies are needed to elucidate the etiology and pathogenesis of chronic prostatitis and to establish guidelines for its diagnosis and treatment.
文摘The significance and diagnostic value of semen analysis in chronic bacterial prostatitis has been extensively debated and remains controversial. To investigate the diagnostic relevance of semen culture in the bacteriological workup of prostatitis patients, we retrospectively analyzed a clinical database of 696 symptomatic patients. All patients were routinely subjected to a four-glass test, followed by semen culture and analysis. This allowed to dissect from the database three different diagnostic scenarios, and to compare the ＇two-glass＇ pre-/post- massage test and the standard ＇four-glass＇ test with a ＇five-glass＇ test （four-glass plus post-VB3 semen culture）. The ＇five-glass＇ test showed 3.6- or 6.5-fold increases in relative sensitivity and lesser reductions （-13.2% or -14.7%） in relative specificity for traditional uropathogens （TUs） compared with the four-glass or two-glass test, respectively. The area under the ROC curve and Jouden＇s index were increased, whereas positive and negative likelihood ratios were lower than comparators, indicating that the ＇five-glass＇ assay may be superior in confirming the negative outcome of both standard tests. The five-, four-, and two-glass tests detected TUs （Enterobacteriaceae, Enterococci, etc.） in 120, 33, and 20 patients and unusual pathogens （Streptococci, other Gram-positive species, Mycoplasmata, and others） in 130, 56, and 45 patients, respectively. When patients were subjected to pharmacological treatment, including a combination of a fluoroquinolone and a macrolide, no differences in eradication rates were observed between groups diagnosed with different tests, irrespective of pathogen category. Eradication was associated with long-term sign/symptom remission; no significant intergroup differences in sign/symptom scores were observed throughout a 24-month off-therapy follow-up period. In conclusion, our data support the usefulness of semen analysis in the diagnostic workup ofprostatitis patients when this test is used to complement the four-glass Meares and Stamey test. Improvement of microbiological assays conveys important diagnostic and therapeutic implications.

文摘Chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS)is a complex disease that is often accompanied by mental health disorders.However,the potential mechanisms underlying the heterogeneous clinical presentation of CP/CPPS remain uncertain.This study analyzed widely targeted metabolomic data of expressed prostatic secretions(EPS)and plasma to reveal the underlying pathological mechanisms of CP/CPPS.A total of 24 CP/CPPS patients from The Second Nanning People’s Hospital(Nanning,China),and 35 asymptomatic control individuals from First Affiliated Hospital of Guangxi Medical University(Nanning,China)were enrolled.The indicators related to CP/CPPS and psychiatric symptoms were recorded.Differential analysis,coexpression network analysis,and correlation analysis were performed to identify metabolites that were specifically altered in patients and associated with various phenotypes of CP/CPPS.The crucial links between EPS and plasma were further investigated.The metabolomic data of EPS from CP/CPPS patients were significantly different from those from control individuals.Pathway analysis revealed dysregulation of amino acid metabolism,lipid metabolism,and the citrate cycle in EPS.The tryptophan metabolic pathway was found to be the most significantly altered pathway associated with distinct CP/CPPS phenotypes.Moreover,the dysregulation of tryptophan and tyrosine metabolism and elevation of oxidative stress-related metabolites in plasma were found to effectively elucidate the development of depression in CP/CPPS.Overall,metabolomic alterations in the EPS and plasma of patients were primarily associated with oxidative damage,energy metabolism abnormalities,neurological impairment,and immune dysregulation.These alterations may be associated with chronic pain,voiding symptoms,reduced fertility,and depression in CP/CPPS.This study provides a local-global perspective for understanding the pathological mechanisms of CP/CPPS and offers potential diagnostic and therapeutic targets.

文摘We investigated the therapeutic effects of superoxide dismutase(SOD)from thermophilic bacterium HB27 on chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS)and its underlying mechanisms.A Sprague–Dawley rat model of CP/CPPS was prepared and then administered saline or Thermus thermophilic(Tt)-SOD intragastrically for 4 weeks.Prostate inflammation and fibrosis were analyzed by hematoxylin and eosin staining,and Masson staining.Alanine transaminase(ALT),aspartate transaminase(AST),serum creatinine(CR),and blood urea nitrogen(BUN)levels were assayed for all animals.Enzyme-linked immunosorbent assays(ELISA)were performed to analyze serum cytokine concentrations and tissue levels of malondialdehyde,nitric oxide,SOD,catalase,and glutathione peroxidase.Reactive oxygen species levels were detected using dichlorofluorescein diacetate.The messenger ribonucleic acid(mRNA)expression of tissue cytokines was analyzed by reverse transcription polymerase chain reaction(RT-PCR),and infiltrating inflammatory cells were examined using immunohistochemistry.Nuclear factor-κB(NF-κB)P65,P38,and inhibitor of nuclear factor-κBα(I-κBα)protein levels were determined using western blot.Tt-SOD significantly improved histopathological changes in CP/CPPS,reduced inflammatory cell infiltration and fibrosis,increased pain threshold,and reduced the prostate index.Tt-SOD treatment showed no significant effect on ALT,AST,CR,or BUN levels.Furthermore,Tt-SOD reduced inflammatory cytokine expression in prostate tissue and increased antioxidant capacity.This anti-inflammatory activity correlated with decreases in the abundance of cluster of differentiation 3(CD3),cluster of differentiation 45(CD45),and macrophage inflammatory protein 1α(MIP1α)cells.Tt-SOD alleviated inflammation and oxidative stress by reducing NF-κB P65 and P38 protein levels and increasing I-κBαprotein levels.These findings support Tt-SOD as a potential drug for CP/CPPS.

文摘Chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS)is highly prevalent worldwide and poses a significant threat to men’s health,particularly affecting young men.However,the exact causes and mechanisms behind CP/CPPS remain unclear,leading to challenges in its treatment.In this research,a CP/CPPS rat model was established with complete Freund’s adjuvant(CFA),and berberine hydrochloride was administered through daily gavage to assess its therapeutic effects.The alterations in the gut microbiome induced by CP/CPPS and berberine hydrochloride were investigated through 16S ribosomal RNA sequencing of cecum content and colonic epithelial cells.To investigate the impact of the gut microbiome on CP/CPPS,a pseudo germ-free rat model was established,and fecal microbiome transplantation(FMT)was performed on these rats.In all,berberine hydrochloride demonstrated effective reduction of inflammation and oxidative stress in the prostate,offering significant therapeutic advantages for CP/CPPS.Through analysis of the gut microbiome using 16S ribosome RNA sequencing,distinct differences were observed between CP/CPPS rats and control rats,and Clostridium butyricum was identified as a key bacteria.Pseudo germ-free rats that underwent FMT from CP/CPPS rats or rats treated with berberine hydrochloride displayed varying levels of inflammatory cytokine production,oxidative stress,and activity of associated signaling pathways.In conclusion,the therapeutic potential of berberine hydrochloride in addressing CP/CPPS is highly significant.The gut microbiome has emerged as a critical factor in the development of CP/CPPS and plays a pivotal role in mediating the therapeutic effects of berberine hydrochloride.
