Symptoms and inflammation in chronic prostatitis/chronic pelvic pain syndrome

Transrectal microwave thermotherapy causing a short-time influence on sperm quality in Chinese chronic nonbacterial prostatitis patients

Chronic prostatitis can affect the sperm's quality. Previous studies have shown that transrectal microwave thermotherapy (TRMT) results in symptomatic relief in patients with chronic prostatitis, but the effects on sperm have not been carefully investigated. This study evaluates the impact of TRMT on the relief or decrease of symptoms and quality of sperm when used to treat patients with chronic nonbacterial prostatitis. Sixty patients were enrolled in the study. TRMT treatment was administered over 5 days, 1 h per day. Semen examination was carried out pretreatment and immediately at the conclusion of the 5-day treatment. Also, it was repeated 1 month, 3 months, and 6 months later. The treatment's symptom relief efficacy was evaluated using the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI). After the treatment, the overall NIH-CPSI scores were lower compared to those of pretreatment. In addition, the white blood cells and lecithin in expressed prostatic secretion were normal after the treatment. The sperm count was decreased by 23.8% 3 months after the treatment, sperm motility was reduced by 10.3% immediately after treatment, and sperm deformity was increased by 17.2%. The sperm volume and PH were not affected. However, the sperm quality recovered after treatment and the malformation rate was also lower at 6 months after treatment. TRMT is a favorable and safe treatment option for patients with nonbacterial chronic prostatitis. It could relieve the patient's symptoms and impact on sperm quality in the short-term.

A prospective study on association of prostatic calcifications with sexual dysfunction in men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS)

INTRODUCTION

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common debilitating condition of unclear etiology. Sexual dysfunction is an important component of the clinical phenotype of CP/CPPS. Patients often have prostatic calcifications, but a link to sexual dysfunction is unknown.

AIM

The aim of this study was to evaluate the association of prostatic calcifications with sexual dysfunction in this condition.

METHODS

A total of 358 males with CP/CPPS were consecutively enrolled, and a prospectively maintained database of these patients was analyzed. Calcifications were diagnosed using ultrasound imaging of the prostate. Symptom severity was measured using the National Institutes of Health Chronic Prostatitis Symptom Index (CPSI). Sexual dysfunction was evaluated using the validated 15-item International Index of Erectile Function (IIEF-15) questionnaire and 5-item Premature Ejaculation Diagnostic Tool scales. The variables were compared between patients with prostatic calcifications and those without using the Student's t-test, Wilcoxon unpaired test, or chi-square test.

MAIN OUTCOME MEASURE

Logistic regression models were developed to explore a possible association between prostatic calcifications and sexual dysfunction.

RESULTS

Measurable calcifications in the prostate were found in 175 (48.9%) of the 358 patients. Patients with calcifications were more likely to have higher white blood cell counts or positive bacteria cultures in their prostatic fluid, longer symptoms duration, and lower scores for the total IIEF-15, IIEF-erectile function, and IIEF-intercourse satisfaction domains (P < 0.001 for each). However, the scores for CPSI, premature ejaculation, and IIEF-orgasmic function, IIEF-sexual desire, and IIEF-overall satisfaction domains were identical between men with and without calcifications (P > 0.05 for each). Furthermore, logistic regression analyses revealed that intraprostatic calcification is significantly associated with self-assessed erectile dysfunction (ED) (odds ratio:3.632, 95% confidence interval: 2.405-5.822, P < 0.001).

CONCLUSION

Our results showed that prostatic calcifications are significantly associated with the presence of ED in CP/CPPS males.

Clinical utility of the UPOINT phenotype system in Chinese males with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS): a prospective study

BACKGROUND

Recent data showed that a six-domain UPOINT is a flexible and responsive new classification system that has the clinical applicability in CP/CPPS. However, the utility of UPOINT algorithm in men in China with CP/CPPS has not been comprehensively studied. For international validation and adoption, we evaluated this clinical phenotype system for a large cohort of Chinese CP/CPPS patients and correlated it with patient symptoms and erectile dysfunction (ED). We also investigated the addition of an ED domain in regard to symptom correlation.

METHODS

A total of 389 Chinese males with CP/CPPS were prospectively collected and classified in each domain of the UPOINT system. Symptom severity was measured using the NIH-CPSI and IPSS. The erectile function was evaluated using the IIEF-5. Clinically relevant associations were calculated.

RESULTS

The percentage of patients positive for each domain was 54.0%, 42.1%, 41.9%, 20.8%, 26.7%, and 40.4% for the Urinary, Psychosocial, Organ-specific, Infection, Neurological/systemic, and Tenderness, respectively. There were significant correlations between the number of positive UPOINT domains and total NIH-CPSI (r = 0.706, p<0.001), IPSS (r = 0.682, p<0.001) and IIEF-5 scores (r = 0.631, P = 0.007) in Chinese cohort. Except for patients age, symptom duration was associated with a significantly greater number of positive domains (r = 0.638, P  = 0.005). After adding an ED domain to create a modified UPOINT system, the correlation between the number of phenotypic domains and symptom severity was improved (0.706 to 0.844, p<0.001).

CONCLUSIONS

The clinical applicability of using UPOINT phenotyping system has been validated in the Chinese patients with CP/CPPS. In our cohort, the number of positive domains was also correlated with ED symptoms and the significant association between the number of UPOINT domains and NIH-CPSI scores was further refined by adding a domain for ED. Our findings presented here support the utility of using ED as a stand-alone item in the UPOINT domain.

Transabdominal ultrasound measurement of pelvic floor muscle mobility in men with and without chronic prostatitis/chronic pelvic pain syndrome

OBJECTIVE

To investigate the pelvic floor muscle motion in men with and without chronic prostatitic/chronic pelvic pain syndrome using transabdominal ultrasound. No study has directly evaluated pelvic floor muscle mobility in individuals with and without chronic pelvic pain syndrome.

METHODS

A convenience sample of 40 males participated in the study. Subjects were categorized into 2 groups: those with chronic pelvic pain syndrome (n = 20) and those without chronic pelvic pain syndrome (n = 20). The amount of bladder base movement on ultrasound (normalized to body mass index) was measured in all subjects and considered as an indicator of pelvic floor muscle mobility.

RESULTS

Statistical analysis (independent t-test) revealed significant difference in transabdominal ultrasound measurements for pelvic floor muscle function between the 2 groups (P = .03, 95% CI -0.26 to -0.01).

CONCLUSION

The results of this study indicate that pelvic floor muscle mobility differs in the 2 groups.

Effectiveness of acupuncture in patients with category IIIB chronic pelvic pain syndrome: a report of 97 patients

OBJECTIVE

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is of significant interest in urology and unfortunately, the therapy modalities recommended are not fully effective. Therefore, we undertook a pilot study to determine whether acupuncture improves the pain, voiding symptoms, and quality of life in men with category IIIB CP/CPPS.

DESIGN

Prospective, one-group trial, cohort study.

SETTING

Outpatient urology clinic.

PATIENTS AND INTERVENTIONS

Ninety-seven CP/CPPS patients received six sessions of acupuncture to the BL-33 acupoints once a week. The National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) was completed by each patient before and after the treatment and on 12th and 24th weeks following the treatment.

OUTCOME MEASURES

Mean values of total CPSI score, pain subscore, urinary subscore, and quality of life subscore after the treatment and on follow-up after the treatment were compared with the baseline values.

RESULTS

There was a statistically significant decrease in all of the subscores evaluated at all periods compared with the baseline. Eighty-six patients out of 93 (92.47%) were NIH-CPSI responders (more than 50% decrease in total NIH-CPSI score from baseline) at the end of the treatment.

CONCLUSIONS

The results of this study suggest that acupuncture appears to be a safe and potentially effective treatment in improving the symptoms and quality of life of men clinically diagnosed with CP/CPPS.

A pilot study on acupuncture for lower urinary tract symptoms related to chronic prostatitis/chronic pelvic pain

Background

The etiology and treatment of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) remain poorly understood. Pain, lower urinary tract voiding symptoms and negative impact on quality of life (QOL) are the most common complaints. Acupuncture, which has been widely used to treat painful and chronic conditions, may be a potential treatment to alleviate the constellation of symptoms experienced by men with CP/CPPS. The purpose of our study was to assess the impact of standardized full body and auricular acupuncture in men refractory to conventional therapies and collect pilot data to warrant further randomized trials.

Methods

Ten men diagnosed with category IIIA or IIIB CP/CPPS >6 months, refractory to at least 1 conventional therapy (antibiotics, anti-inflammatory agents, 5-α reductase inhibitors, α-1 blockers) and scoring >4 on the pain subset of the NIH-CPSI were prospectively analyzed in an Institutional Review Board (IRB) approved, single-center clinical trial (Columbia University Medical Center IRB#AAAA-7460). Standardized full body and auricular acupuncture treatment was given twice weekly for 6 weeks. The primary endpoints were total score of the NIH-CPSI and assessment of serious adverse events. The secondary endpoints were individual scores of the NIH-CPSI and QOL questionnaire scores of the short-form 36 (SF-36).

Results

The median age of the subjects was 36 years (range 29–63). Decreases in total NIH-CPSI scores (mean ± SD) after 3 and 6 weeks from baseline (25.1 ± 6.6) were 17.6 ± 5.7 (P < 0.006) and 8.8 ± 6.2 (P < 0.006) respectively and remained significant after an additional 6 weeks of follow-up (P < 0.006). Symptom and QOL/NIH-CPSI sub-scores were also significant (P < 0.002 and P < 0.002 respectively). Significance in 6 of 8 categories of the SF-36 including bodily pain (P < 0.002) was achieved. One regression in the SF-36 vitality category was observed after follow-up. There were no adverse events.

Conclusion

The preliminary findings, although limited, suggest the potential therapeutic role of acupuncture in the treatment of CP/CPPS. Data from this and previous studies warrant randomized trials of acupuncture for CP/CPPS and particular attention towards acupuncture point selection, treatment intervention, and durability of acupuncture.

Demographic and clinical characteristics of chronic prostatitis: prospective comparison of the University of Sciences Malaysia Cohort with the United States National Institutes of Health Cohort

PURPOSE

We compared demographic and clinical characteristics of the University of Sciences Malaysia Chronic Prostatitis Cohort to the United States National Institutes of Health Chronic Prostatitis Cohort.

MATERIALS AND METHODS

Participants met the same definition of chronic prostatitis/chronic pelvic pain syndrome. Each participant had extensive demographic, medical history, previous treatment, clinical and laboratory evaluations.

RESULTS

The University of Sciences Malaysia and National Institutes of Health cohorts proved similar in most respects. National Institutes of Health-Chronic Prostatitis Symptom Index total scores, pain and urinary subscores were similar for the 332 University of Sciences Malaysia Chronic Prostatitis Cohort and 488 National Institutes of Health Chronic Prostatitis Cohort participants. Differences included worse quality of life subscore for the University of Sciences Malaysia Chronic Prostatitis Cohort, differences in the location, number of sites, and types of pain/discomfort between the 2 populations, and that the University of Sciences Malaysia participants had received less previous treatment.

CONCLUSIONS

The demographic characteristics and clinical presentation of chronic prostatitis/chronic pelvic pain syndrome proved remarkably similar in these diverse populations. Both cohorts experienced major reduction in their quality of life from chronic pelvic pain and urinary symptoms. Comparison of diverse populations using standard clinical, laboratory and assessment instruments is feasible, and may provide important insights into chronic prostatitis/chronic pelvic pain syndrome and the factors that determine clinical outcome.

Safety and efficacy of tamsulosin in the treatment of painful ejaculation: a randomized, double-blind, placebo-controlled study

We evaluate the efficacy and safety of tamsulosin a selective alpha(1A)-receptor antagonist in patients with painful ejaculation (PE) as a sole entity. A total of 118 men with PE were included in the study. Patients were randomly assigned to receive 0.4 mg oral daily tamsulosin (group 1, n=59) or placebo (group 2, n=59), during a 6-week period for each agent. Pretreatment evaluation included history and physical examination, International Index of Erectile Function (IIEF) and a visual analog scale (VAS) for pain. The efficacy of two treatments was assessed every 2 weeks during treatment, and at the end of the study using responses to IIEF, VAS evaluation, mean intercourse satisfaction domain, mean weekly coitus episodes and adverse drug effects. In all, 104 patients (88%) completed the whole treatment schedule. Pain resolved in 16 and 13% of the patients treated with tamsulosin and placebo, respectively (P=0.1). Baseline mean intercourse satisfaction domain values of IIEF 10 and 11 reached to 12 and 10 at 6-week treatment in groups 1 and 2, respectively (P=0.08). The VAS after tamsulosin and placebo decreased from 5.7 and 5.8 to 5.1 and 5.5, respectively (P=0.1). The mean weekly intercourse episodes increased from pretreatment values of 1.8 and 1.6 to 1.9 and 1.7, for tamsulosin and placebo, respectively (P=0.08). Mean number of adverse events was 11 for tamsulosin and 5 for placebo (P<0.05). Tamsulosin is no better than placebo in improvement of PE as a sole entity.

Complementary and alternative medicine for chronic prostatitis/chronic pelvic pain syndrome

To discuss challenges concerning treatment for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and review complementary and alternative medical (CAM) therapies being evaluated for this condition, we performed a comprehensive search of articles published from 1990-2005 using the PubMed, Medline databases. Data from the articles were abstracted and pooled by subject. Keywords cross-searched with CP/CPPS included: complementary, alternative, integrative, therapies, interventions, nutrition, antioxidants, herbs, supplements, biofeedback and acupuncture. Listed articles with no abstracts were not included. Various CAM therapies for CP/CPPS exist including biofeedback, acupuncture, hyperthermia and electrostimulation. Additionally, a variety of in vitro and in vivo studies testing herbal and nutritional supplements were found. Saw palmetto, cernilton and quercetin were the most frequently tested supplements for CP/CPPS. Although many CAM therapies demonstrate positive preliminary observations as prospective treatments for CP/CPPS, further exploratory studies including more randomized, controlled trials are necessary for significant validation as treatment options for this complex disorder.

Management of ejaculation pain with topiramate: a case report

A 39-year-old male presented with penile pain related to ejaculation. No urogenital, infectious, or neurologic diseases were associated with the symptoms. The pain was refractory to conventional analgesics and several neuropathic pain therapies. Oral topiramate was titrated to 75 mg daily, and within a month, the patient's pain improved from 8 to 1 out of 10, which has been maintained for 6 months.

Counting leukocytes in expressed prostatic secretions from patients with chronic prostatitis/chronic pelvic pain syndrome

OBJECTIVES

The evaluation of WBCs in EPS is recommended for classifying patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) but no agreement has been reached on the optimal method. We sought to determine the relationship between the expressed prostatic secretions (EPS) leukocyte (WBC) count per high-power field (evaluated by a more quantitative wet mount method and the traditional gram-stained smear method used in clinical microbiology laboratories) and the EPS WBC concentration to determine whether quantitative methods are necessary for accurate patient classification.

METHODS

EPS collected from 94 patients with CP/CPPS were evaluated by gram-stained smear, a standardized wet mount, and a hemocytometer method.

RESULTS

The gram-stained smear detected EPS WBCs in 21 (22%) of 94 subjects compared with 78 (83%) by the standardized wet mount and 57 (60%) by the hemocytometer method. The gram-stained EPS WBC count correlated poorly with the WBC concentration by hemocytometer (R(2) = 0.051, P = 0.03). Although the standardized EPS WBC count correlated better with the concentration by hemocytometer, the correlation coefficient remained low (R(2) = 0.244, P <0.0001).

CONCLUSIONS

The standardized wet mount proved superior to the gram-stained smear, but both methods lacked precision. Quantitative determination of the EPS WBC concentration by a counting chamber method proved to be the superior evaluation for research studies of CP/CPPS.
