Results of treatment with pollen extract (Cernilton N) in chronic prostatitis and prostatodynia

A Novel Insight into the Immune-Related Interaction of Inflammatory Cytokines in Benign Prostatic Hyperplasia

Benign prostatic hyperplasia (BPH) is a common male condition that impacts many men's quality of life by generating lower urinary tract symptoms (LUTS). In recent years, inflammation has become very common in the prostate, and BPH with inflammation has a higher International Prostate Symptom Score (IPSS) score and an enlarged prostate. Chronic inflammation leads to tissue damage and the release of pro-inflammatory cytokines, which play an important role in the pathogenesis of BPH. We will focus on current advancements in pro-inflammatory cytokines in BPH, as well as the future of pro-inflammatory cytokine research.

The efficacy and tolerability of pollen extract in combination with hyaluronic acid and vitamins in the management of patients affected by chronic prostatitis/chronic pelvic pain syndrome: a 26 weeks, randomized, controlled, single-blinded, phase III study

BACKGROUND

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) remains a challenging clinical condition to manage. Here, we evaluate the efficacy and tolerability of a new treatment option (suppositories) containing pollen extract in combination with hyaluronic acid and vitamins in the management of patients with CP/CPPS.

METHODS

In this prospective, randomized, controlled, single-blinded, phase-III study we enrolled CP/CPPS patients between March and December 2019. Participants were randomized (1:1) to the following treatment groups: 1) pollen extract suppositories 1 daily for 10 days; or 2) ibuprofen 600 mg 1 tablet in the morning for 10 days. At the enrolment time and at the follow-up evaluations (3, 6 months), all patients completed baseline questionnaires ([National Institutes of Health Chronic Prostatitis Symptom Index [NIH-CPSI] and Quality of Well-Being [QoL]) and underwent urological examination and microbiological evaluation. The primary endpoint was the quality-of-life assessment with Patients' Reported Outcomes (PROs).

RESULTS

One hundred and eighty-seven patients were screened. Finally, one hundred and twenty-four patients (mean age 34.6±3.9 years) were randomly allocated to the new pollen extract treatment (N.=63) or ibuprofen (N.=61) groups. At the end of follow-up examinations 56/63 group 1 patients (88.8%) showed a significant reduction of the NIH-CPSI total score, compared with 17/61 (27.8%) in group 2 (P<0.0001). Group 1 patients also reported a higher improvement in terms of PROs, when compared with the control group and group 1 patients reported a significant reduction of leucocyte count at the Meares-Stamey Test (-12; -4; P<0.001). Only mild adverse events were reported in the two groups and adverse events were less frequent in the pollen extract suppositories group.

CONCLUSIONS

The combination of pollen extract with hyaluronic acid and vitamins is more effective than ibuprofen in improving symptoms and Quality of Life in patients affected with CP/CPPS and has less side effects.

Bee Pollen: Clinical Trials and Patent Applications

Bee pollen is a natural cocktail of floral nectar, flower pollen, enzymes, and salivary secretions produced by honeybees. Bee pollen is one of the bee products most enriched in proteins, polysaccharides, polyphenols, lipids, minerals, and vitamins. It has a significant health and medicinal impact and provides protection against many diseases, including diabetes, cancer, infectious, and cardiovascular. Bee pollen is commonly promoted as a cost-effective functional food. In particular, bee pollen has been applied in clinical trials for allergies and prostate illnesses, with a few investigations on cancer and skin problems. However, it is involved in several patents and health recipes to combat chronic health problems. This review aimed to highlight the clinical trials and patents involving bee pollen for different cases and to present the role of bee pollen as a supplementary food and a potential product in cosmetic applications.

Indigenous knowledge system associated with the uses of insects for therapeutic or medicinal purposes in two main provinces of Burkina Faso, West Africa

BACKGROUND

Some insects are harmful to humans, plants and animals, but some of them can also be a source of proteins, fats, vitamins and minerals and be of therapeutic value. The therapeutic potential requires that medicinal insects and their derived products need to be scrutinized. This study highlights the indigenous knowledge related to their use of medicinal insects in peri-urban and urban areas of Burkina Faso.

METHODS

The survey was carried out among 60 traditional healers spread across two phytogeographical zones of Burkina Faso. The questionnaire focused on medicinal insects used by experienced traditional healers. Chi-square tests and principal component analysis were performed to test for significant differences regarding knowledge of how insects in phytogeographically different areas were used therapeutically in connection with different disease categories.

RESULTS

A total of 19 species of medicinal insects belonging to 6 orders were cited in connection with treatments of at least 78 pathologies and symptoms. Most frequently mentioned was gastroenteritis. Our study showed that 48.78% of the insects and their products were associated with 46 plant species for the treatment of pathologies. In addition, honey, beeswax and nests were the most widely insect products used.

CONCLUSION

The current study allows us to identify medicinal insects as well as their products used in the treatment of pathologies and symptoms, suggesting the presence of a considerable diversity of therapeutically important insect species. These insects are used alone and/or with their products but often in association with medicinal plants. The results constitute a useful database for future studies of medicinal insects in central and western parts of Burkina Faso.

Treatment of Benign Prostatic Hyperplasia by Natural Drugs

Benign prostatic hyperplasia (BPH) is one of the most common urinary diseases affecting men, generally after the age of 50. The prevalence of this multifactorial disease increases with age. With aging, the plasma level of testosterone decreases, as well as the testosterone/estrogen ratio, resulting in increased estrogen activity, which may facilitate the hyperplasia of the prostate cells. Another theory focuses on dihydrotestosterone (DHT) and the activity of the enzyme 5α-reductase, which converts testosterone to DHT. In older men, the activity of this enzyme increases, leading to a decreased testosterone/DHT ratio. DHT may promote prostate cell growth, resulting in hyperplasia. Some medicinal plants and their compounds act by modulating this enzyme, and have the above-mentioned targets. This review focuses on herbal drugs that are most widely used in the treatment of BPH, including pumpkin seed, willow herb, tomato, maritime pine bark, Pygeum africanum bark, rye pollen, saw palmetto fruit, and nettle root, highlighting the latest results of preclinical and clinical studies, as well as safety issues. In addition, the pharmaceutical care and other therapeutic options of BPH, including pharmacotherapy and surgical options, are discussed, summarizing and comparing the advantages and disadvantages of each therapy.

Bee Collected Pollen and Bee Bread: Bioactive Constituents and Health Benefits

Bee products were historically used as a therapheutic approach and in food consumption, while more recent data include important details that could validate them as food supplements due to their bioproperties, which support their future use as medicines. In this review data, data collected from bee pollen (BP) and bee bread (BB) essays will be discussed and detailed for their nutritional and health protective properties as functional foods. Dietary antioxidants intake derived from BP and BB have been associated with the prevention and clinical treatment of multiple diseases. The beneficial effects of BP and BB on health result from the presence of multiple polyphenols which possess anti-inflammatory properties, phytosterols and fatty acids, which play anticancerogenic roles, as well as polysaccharides, which stimulate immunological activity. From the main bioactivity studies with BP and BB, in vitro studies and animal experiments, the stimulation of apoptosis and the inhibition of cell proliferation in multiple cell lines could be one of the major therapeutic adjuvant effects to be explored in reducing tumor growth. Tables summarizing the main data available in this field and information about other bio-effects of BP and BB, which support the conclusions, are provided. Additionally, a discussion about the research gaps will be presented to help further experiments that complete the tree main World Health Organization (WHO) Directives of Efficiency, Safety and Quality Control for these products.

Flower Pollen Extract in Association with Vitamins (Deprox 500®) Versus Serenoa repens in Chronic Prostatitis/Chronic Pelvic Pain Syndrome: A Comparative Analysis of Two Different Treatments

Objective:

Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) is re-ported in the literature ranging from 1 to 14.2%. The aim of the present study was to as-sess the impact on patient’s quality of life and symptoms of Flower pollen extract in asso-ciation with vitamins (Deprox 500®) in comparison with Serenoa repens 320 mg (Permix-on 320 mg® by Pierre Fabre) in patients with CP/CPPS.

Methodology:

All consecutive patients, with a diagnosis of CP/CPPS, referred to our center from January to August 2016, were screened to be enrolled in this single-center, random-ized, controlled trial. The main outcome measure was the evaluation of IPSS/NIH-CPSI (International Prostatic Symptom Score/NIH-Chronic Prostatitis Symptom Index) score variation and the assessment of the quality of life and symptoms at the end of the thera-py. The second outcome measure was the evaluation of the comorbidity role in the CP/CPPS therapy. 63 patients were analyzed; patients were randomized into two groups: 29 patients were treated with Deprox 500® 2 tablets/day for 6 weeks and 34 patients with Serenoa repens 320 mg, 1 tablet/day for 6 weeks.

Results:

The mean score variation for IPSS was -12.7 ± 4.3 in the Deprox 500® group and -7.8 ± 4.7 in the Serenoa repens group (p=0.0005) while for NIH-CPSI was -17.3±3.1 in the Deprox 500® group and -13.6±4.8 in the Serenoa repens group (p=0.0016). By ac-counting only the symptoms part of NIH-CPSI questionnaire, the mean score variation reported was -11.5±2.5 in the Deprox 500® group and -9.02±4.0 in the Serenoa repens group (p=0.009321). Furthermore, analyzing the comorbidity subgroups, in patients with hypertension, the mean IPSS score variation was -14.3±3.2 in the Deprox 500® group and -9.02±4.0 in the Serenoa repens group.

Conclusion:

In conclusion, in patients with CP/CPPS, Deprox 500® improves IPSS and NIH-CPSI scores up to 74.5% and 84.5% respectively. Furthermore, in patients with hypertension, the antioxidant effect of Deprox 500® reduces the mean IPSS score of 82.7%.

The Effect of Flavonoids on Chronic Prostatitis: A Meta-analysis of Published Randomized Controlled Trials

OBJECTIVE

To assess the effect of flavonoids on chronic prostatitis, a meta-analysis of randomized controlled trials was performed.

METHODS

Through using subject word and random word, PubMed, Scopus, Web of Science, and Cochrane Library were searched for related records up to July 2018. The response rate and National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) were used to evaluate the therapeutic efficacy of the flavonoids. The Cochrane handbook for systematic reviews of interventions version was used to evaluate the quality of included studies. The model of determining odds ratio (OR) was chose according to the value of I².

RESULTS

A total of 11 studies involving 975 subjects (experiment 516, control 459) were included. The overall OR of response rate was 0.31 (95%CI 0.11-0.89, P = 0.03). At the subgroup analysis, the OR of response rate of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) was 0.57 (95%CI 0.18-1.77, P = 0.33), while the OR of response rate of chronic bacterial prostatitis (CBP) was 0.08 (95%CI 0.02-0.33, P = 0.0005). The OR of response rate of CP/CPPS (control was placebo) was 0.29 (95%CI 0.16-0.52, P < 0.0001). The overall OR of baseline NIH-CPSI was -0.1 (95%CI -0.61-0.41, P = 0.70). The overall OR of posttreatment NIH-CPSI was -6.96 (95%CI -8.32∼ -5.60, P < 0.00001).

CONCLUSIONS

This meta-analysis indicates that the flavonoids may be clinically beneficial through significantly improving the response rate and NIH-CPSI in chronic prostatitis patients and short-lasting antibiotics therapy in association with the flavonoids could be a better choose for CBP. Moreover, the flavonoids therapy has an excellent safety profile with minor adverse effects.

Prostatitis Syndromes and Sporting Activities

Introduction

Prostatitis-like syndromes are high prevalent health problems and frequently considered by patients and physicians as strictly correlated to sports causing perineal compression. These syndromes and their relationships with sporting activities have been discussed in this report.

Methods

We reviewed peer-reviewed scientific articles published by May 2009 and searched according to the following term selection: prostatitis, pudendal nerve, sport, cycling.

Results

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a major healthcare burden heavily affecting patients’ Quality of Life. No clear evidence of any direct etiologic relationship has been found in literature between prostatitis, either bacterial or non-bacterial, and sports activities. On the other hand, some types of sport causing perineal compression, such as cycling, can exacerbate symptoms of acute and chronic prostatitis; a temporary sport discontinuation is justified in these patients. CP/CPPS may be often caused by pudendal nerve entrapment (PNE). Prostatitis-like urogenital neuropathic pain together with voiding and sexual dysfunctions are the hallmark of PNE. A common feature is that flexion activities of the hip, such as climbing, squatting, cycling provoke or worsen urogenital pain or pelvic pain. Many of the patients with PNE are cyclists, played American football, lifted weights, or wrestled as teenagers and young adults. PNE represents the most common bicycling associated urogenital problems.

Conclusions

Overall, studies show that no causal relationship has been demonstrated between prostatitis and sporting activities. Conversely, urologists should be aware that sports involving vigorous hip flexion activities or prolonged perineal compression are a potential and not an infrequent cause of uroand rological symptoms caused by pudendal nerve entrapment.

The Clinical Efficacy of Pollen Extract and Vitamins on Chronic Prostatitis/Chronic Pelvic Pain Syndrome Is Linked to a Decrease in the Pro-Inflammatory Cytokine Interleukin-8

PURPOSE

We aim to evaluate the efficacy of pollen extract in association with vitamins in patients affected by chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and to evaluate the level of the pro-inflammatory mediators interleukin (IL)-6, IL-8, and IL-10.

MATERIALS AND METHODS

Patients diagnosed with CP/CPPS between January and December 2015 were enrolled in this study. Participants were randomly assigned to receive oral capsules of pollen extract and vitamins (group A) or bromelain (group B) for 3 months. At the enrolment time and 3 months after enrolment, all patients completed questionnaires (the National Institutes of Health Chronic Prostatitis Symptom Index [NIH-CPSI] and the Short Form-36 and underwent urological examinations and microbiological evaluation. Levels of IL-6, IL-8, and IL-10 were evaluated in seminal plasma.

RESULTS

Sixty-five male patients (mean age of 32.7±4.7 years) were analysed (group A, n=32; group B, n=33). At the follow-up examination, 24 of the 32 patients in group A showed a significant reduction in the NIH-CPSI total score compared with 8 of the 33 patients in the bromelain group (p<0.001). Moreover, the mean level of IL-8 was significantly lower in the pollen extract and vitamins group when compared with the bromelain group (298 pg/mL vs. 736 pg/mL, respectively; p<0.001). In group A we found a statistically significant reduction in the levels of IL-8 between enrolment and the follow-up visit (878 pg/mL vs. 298 pg/mL, respectively; p<0.001).

CONCLUSIONS

Treatment with pollen extract and vitamins improved the quality of life in CP/CPPS patients by reducing the levels of pro-inflammatory IL-8.

The role of flower pollen extract in managing patients affected by chronic prostatitis/chronic pelvic pain syndrome: a comprehensive analysis of all published clinical trials

BACKGROUND

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is still a challenge to manage for all physicians. We feel that a summary of the current literature and a systematic review to evaluate the therapeutic efficacy of flower pollen extract would be helpful for physicians who are considering a phytotherapeutic approach to treating patients with CP/CPPS.

METHODS

A comprehensive search of the PubMed and Embase databases up to June 2016 was performed. This comprehensive analysis included both pre-clinical and clinical trials on the role of flower pollen extract in CP/CPPS patients. Moreover, a meta-analysis of available randomized controlled trials (RCTs) was performed. The NIH Chronic Prostatitis Symptom Index (NIH-CPSI) and Quality of Life related questionnaires (QoL) were the most commonly used tools to evaluate the therapeutic efficacy of pollen extract.

RESULTS

Pre-clinical studies demonstrated the anti-inflammatory and anti-proliferative role of pollen extract. 6 clinical, non-controlled studies including 206 patients, and 4 RCTs including 384 patients were conducted. The mean response rate in non-controlled studies was 83.6% (62.2%-96.0%). The meta-analysis revealed that flower pollen extract could significantly improve patients' quality of life [OR 0.52 (0.34-.0.81); p = 0.02]. No significant adverse events were reported.

CONCLUSION

Most of these studies presented encouraging results in terms of variations in NIH-CPSI and QoL scores. These studies suggest that the use of flower pollen extract for the management of CP/CPPS patients is beneficial. Future publications of robust evidence from additional RCTs and longer-term follow-up would provide more support encouraging the use of flower pollen extracts for CP/CPPS patients.

Use of the UPOINT phenotype system in treating Chinese patients with chronic prostatitis/chronic pelvic pain syndrome: a prospective study

The urinary, psychosocial, organ-specific, infection, neurological/systemic and tenderness (UPOINT) phenotype system has been validated to be an effective phenotype system in classifying patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) in western populations. To validate the utility of the UPOINT system and evaluate the effect of multimodal therapy based on the UPOINT system in Chinese patients with CP/CPPS, we performed this study. Chinese patients with CP/CPPS were prospectively offered multimodal therapy using the UPOINT system and re-examined after 6 months. A minimum 6-point drop in National Institutes of Health-Chronic Prostatitis Symptoms Index (NIH-CPSI) was set to be the primary endpoint. Finally, 140 patients were enrolled in the study. The percentage of patients with each domain was 59.3%, 45.0%, 49.3%, 22.1%, 37.9%, and 56.4% for the UPOINT, respectively. The number of positive domains significantly correlated with symptom severity, which is measured by total NIH-CPSI scores (r = 0.796, P< 0.001). Symptom duration was associated with a greater number of positive domains (r = 0.589, P< 0.001). With 6 months follow-up at least, 75.0% (105/140) had at least a 6-point improvement in NIH-CPSI after taking the therapy. All NIH-CPSI scores were significantly improved from original ones: pain 10.14 ± 4.26 to 6.60 ± 3.39, urinary 6.29 ± 2.42 to 3.63 ± 1.52, quality of life 6.56 ± 2.44 to 4.06 ± 1.98, and total 22.99 ± 7.28 to 14.29 ± 5.70 (all P< 0.0001). Our study indicates that the UPOINT system is clinically feasible in classifying Chinese patients with CP/CPPS and directing therapy.

Pollen extract in association with vitamins provides early pain relief in patients affected by chronic prostatitis/chronic pelvic pain syndrome

The therapeutic efficacy for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is currently unsatisfactory. The aim of the present study was to assess the safety and efficacy of pollen extract in association with vitamins (DEPROX 500^®) in males with CP/CPPS. All patients with a diagnosis of CP/CPPS attending the same urologic centre between March and October 2012 were enrolled in this randomised controlled phase III study. Participants were randomised to receive oral capsules of DEPROX 500^® (two capsules every 24 h) or ibuprofen (600 mg, one tablet three times a day) for four weeks. The National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), International Prostate Symptom Score and Quality of Well-Being (QoL) questionnaires were used. In the intention-to-treat analysis, 87 males (25 class IIIa and 62 class IIIb) with a mean age of 33.6±5.9 years were randomly allocated to the DEPROX 500^® (n=41) or ibuprofen (n=46) treatment groups. At the follow-up examination (following one month of treatment), in the DEPROX 500^® group, 31/41 patients (75.6%) reported an improvement in quality of life, defined as a reduction of the NIH-CPSI total score by ≥25%, compared with 19/46 (41.3%) in the control group (P=0.002). The greater improvement in the DEPROX 500^® group compared with the ibuprofen group was statistically significant (treatment difference in the NIH-CPSI pain domain, −2.14±0.51, P<0.001; QoL scores, P=0.002). All patients were negative at the Meares-Stamey test evaluation. Adverse events were less frequent in the DEPROX 500^® group than in the ibuprofen group. The DEPROX 500^® treatment significantly improved total symptoms, pain and quality of life compared with ibuprofen in patients with CP/CPPS, without severe side-effects.

Pollen extract for chronic prostatitis-chronic pelvic pain syndrome

Prostatitis syndrome is a frequent condition in men. It is not known in most patients if the prostate is the only organ involved. Therefore, the disease is characterized as chronic prostatitis-chronic pelvic pain syndrome (CP-CPPS). Although many studies have been performed in patients with CP-CPPS, current trial evidence is conflicting and therapeutic options are controversial. Given the need for long-term treatment in CP-CPPS patients, phytotherapeutics, such as pollen extract, are an option due to few side effects. Preclinical studies on pollen extract have shown effects on smooth muscles of the bladder and urethra, strong antiinflammatory effects, and antiproliferative effects.

Prostatitis and chronic pelvic pain syndrome in men

Primary care physicians can and should diagnose, classify, and treat patients presenting with acute and chronic prostatitis syndromes. Although the chronic syndromes are a challenge to manage, this review article provides the necessary background to allow primary care physicians to take on this task. Patients who are unfortunate to be diagnosed with a prostatitis syndrome have the best chance for successful therapy at initial presentation. Those patients will ultimately benefit from an informed and educated physician.

Pharmacotherapy of prostatitis

IMPORTANCE OF THE FIELD

Prostatitis is a prevalent and morbid condition with a significant impact on a patient's quality of life. The four distinct prostatitis syndromes have different pathophysiologies, therapy and prognosis. Acute and chronic bacterial prostatitis is best treated with appropriate antibiotics that penetrate the prostate and kill the causative organisms. The most challenging category to treat is category III or chronic prostatitis/chronic pelvic pain syndrome.

AREAS COVERED IN THE REVIEW

This review covers the categories of prostatitis and currently recommended therapies, as well as novel approaches on the horizon.

WHAT THE READER WILL GAIN

Knowledge of the current framework for the diagnosis and management of the diverse prostatitis spectrum.

TAKE HOME MESSAGE

Prostatitis is a diverse group of syndromes. Chronic prostatitis/chronic pelvic pain syndrome is a multifactorial syndrome that requires a multimodal approach to effectively treat the patient. The UPOINT technique is used to clinically phenotype these patients and drive the selection of multimodal therapy.

Use of the UPOINT chronic prostatitis/chronic pelvic pain syndrome classification in European patient cohorts: sexual function domain improves correlations

PURPOSE

Patients with chronic prostatitis-chronic pelvic pain syndrome are difficult to treat due to the unknown etiology and complex clinical presentation. Clinical phenotyping may better correlate with multimodal treatment concepts than a current diagnosis. We evaluated a novel clinical phenotyping system in a database of patients with chronic prostatitis-chronic pelvic pain syndrome at 2 European institutions and correlated it with patient symptoms. We also investigated the addition of a sexual dysfunction domain in regard to symptom correlation and system internal consistency.

MATERIALS AND METHODS

We retrospectively classified 937 patients from Milan, Italy, and 290 from Giessen, Germany, with chronic prostatitis-chronic pelvic pain syndrome into a 6-domain phenotyping system, consisting of urinary, psychosocial, organ specific, infection, neurological and muscle tenderness domains, termed UPOINT. Symptom severity was assessed by the National Institutes of Health Chronic Prostatitis Symptom Index and the International Prostate Symptom Score.

RESULTS

There was significant correlation between the number of positive UPOINT domains and Chronic Prostatitis Symptom Index/International Prostate Symptom Score symptoms in the total and Italian cohorts but not in the German cohort. After adding a sexual dysfunction domain to create the modified UPOINTS system phenotypic domains also correlated significantly with Chronic Prostatitis Symptom Index symptoms in the German cohort.

CONCLUSIONS

Consistency of the UPOINT chronic prostatitis-chronic pelvic pain syndrome clinical phenotyping system was generally confirmed by our study and further refined by adding a sexual dysfunction domain. The treatment effect of clinical phenotyping with UPOINT(S) must be extensively evaluated in prospective treatment studies.

[Urethral syndrome in men--chronic pelvic pain syndrome]

INTRODUCTION

Chronic pelvic pain syndrome (CPPS) is defined as pelvis minor pain of nonmalignant nature repeating in different time intervals. Urethral syndrome (US) represents a most poorly defined entity within CPPS.

OBJECTIVE

The estimation of US influence on quality-of-life as well as the determination of the way of treatment and therapy optimal length.

MATERIAL AND METHODS

A prospective one-year study included 166 men with CPPS, median age of 54 years; they were monitored clinically. During the patient monitoring the NIH-CPSI questionnaire (National Institute of Health-Chronic Prostatis Symptom Index) was used. US was diagnosed in 79 patients (47%), and according to the most intensive pain localization they were divided into three groups. All the patients were treated with alpha adrenergic blockers and non-steroidal anti-inflammatory drugs, and the treatment of the patients with positive urethral smear also included antibiotherapy. The values of total NIH-CPSI, as well as of its individual components were analyzed after three and six months of treatment.

RESULTS AND DISCUSSION

The therapy application had a significant influence on the decrease of total NIH-CPSI--23.3% (p < 0.01), pain symptoms (p < 0.0) and urinary difficulties (p < 0.01), and the point values of quality-of-life score were diminished by 0.7 to 1.9 points depending on the group of those monitored (p < 0.01).

CONCLUSION

Our study indicated a significant influence of CPPS on quality-of-life and a necessity of a serious approach to patients and their treatment.

A pollen extract (Cernilton) in patients with inflammatory chronic prostatitis-chronic pelvic pain syndrome: a multicentre, randomised, prospective, double-blind, placebo-controlled phase 3 study

BACKGROUND

National Institutes of Health (NIH) category III prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a prevalent condition for which no standardised treatment exists.

OBJECTIVES

To assess the safety and efficacy of a standardised pollen extract in men with inflammatory CP/CPPS.

DESIGN, SETTING, AND PARTICIPANTS

We conducted a multicentre, prospective, randomised, double-blind, placebo-controlled phase 3 study comparing the pollen extract (Cernilton) to placebo in men with CP/CPPS (NIH IIIA) attending urologic centres.

INTERVENTION

Participants were randomised to receive oral capsules of the pollen extract (two capsules q8h) or placebo for 12 wk.

MEASUREMENTS

The primary endpoint of the study was symptomatic improvement in the pain domain of the NIH Chronic Prostatitis Symptom Index (NIH-CPSI). Participants were evaluated using the NIH-CPSI individual domains and total score, the number of leukocytes in post-prostatic massage urine (VB3), the International Prostate Symptom Score (IPSS), and the sexuality domain of a life satisfaction questionnaire at baseline and after 6 and 12 wk.

RESULTS AND LIMITATIONS

In the intention-to-treat analysis, 139 men were randomly allocated to the pollen extract (n=70) or placebo (n=69). The individual domains pain (p=0.0086) and quality of life (QoL; p=0.0250) as well as the total NIH-CPSI score (p=0.0126) were significantly improved after 12 wk of treatment with pollen extract compared to placebo. Response, defined as a decrease of the NIH-CPSI total score by at least 25% or at least 6 points, was seen in the pollen extract versus placebo group in 70.6% and 50.0% (p=0.0141), respectively. Adverse events were minor in all patients studied.

CONCLUSIONS

Compared to placebo, the pollen extract significantly improved total symptoms, pain, and QoL in patients with inflammatory CP/CPPS without severe side-effects.

Chronic prostatitis: management strategies

The National Institutes of Health (NIH) has redefined prostatitis into four distinct entities. Category I is acute bacterial prostatitis. It is an acute prostatic infection with a uropathogen, often with systemic symptoms of fever, chills and hypotension. The treatment hinges on antimicrobials and drainage of the bladder because the inflamed prostate may block urinary flow. Category II prostatitis is called chronic bacterial prostatitis. It is characterized by recurrent episodes of documented urinary tract infections with the same uropathogen and causes pelvic pain, urinary symptoms and ejaculatory pain. It is diagnosed by means of localization cultures that are 90% accurate in localizing the source of recurrent infections within the lower urinary tract. Asymptomatic inflammatory prostatitis comprises NIH category IV. This entity is, by definition, asymptomatic and is often diagnosed incidentally during the evaluation of infertility or prostate cancer. The clinical significance of category IV prostatitis is unknown and it is often left untreated. Category III prostatitis is called chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). It is characterized by pelvic pain for more than 3 of the previous 6 months, urinary symptoms and painful ejaculation, without documented urinary tract infections from uropathogens. The syndrome can be devastating, affecting 10-15% of the male population, and results in nearly 2 million outpatient visits each year. The aetiology of CP/CPPS is poorly understood, but may be the result of an infectious or inflammatory initiator that results in neurological injury and eventually results in pelvic floor dysfunction in the form of increased pelvic muscle tone. The diagnosis relies on separating this entity from chronic bacterial prostatitis. If there is no history of documented urinary tract infections with a urinary tract pathogen, then cultures should be taken when patients are symptomatic. Prostatic localization cultures, called the Meares-Stamey 4 glass test, would identify the prostate as the source for a urinary tract infection in chronic bacterial prostatitis. If there is no infection, then the patient is likely to have CP/CPPS. For healthcare providers, the focus of therapy is symptomatic relief. The first therapeutic measure is often a 4- to 6-week course of a fluoroquinolone, which provides relief in 50% of men and is more efficacious if prescribed soon after symptoms begin. Second-line pharmacotherapy involves anti-inflammatory agents for pain symptoms and alpha-adrenergic receptor antagonists (alpha-blockers) for urinary symptoms. Potentially more effective is pelvic floor training/biofeedback, but randomized controlled trials are needed to confirm this. Third-line agents include 5alpha-reductase inhibitors, glycosaminoglycans, quercetin, cernilton (CN-009) and saw palmetto. For treatment refractory patients, surgical interventions can be offered. Transurethral microwave therapy to ablate prostatic tissue has shown some promise. The treatment algorithm provided in this review involves a 4- to 6-week course of antibacterials, which may be repeated if the initial course provides relief. Pain and urinary symptoms can be ameliorated with anti-inflammatories and alpha-blockers. If the relief is not significant, then patients should be referred for biofeedback. Minimally invasive surgical options should be reserved for treatment-refractory patients.

Incidence and significance of prostatic stones in men with chronic prostatitis/chronic pelvic pain syndrome

OBJECTIVES

Prostatic calcification is common in asymptomatic elderly men. However, young men with chronic pelvic pain syndrome (CPPS) often have significantly calcified prostates. We studied the incidence and significance of prostatic calcification in men with CPPS.

METHODS

From July 2005 to August 2006, 130 new patients with CPPS were seen at our clinic. Of these 130 patients, 47 underwent transrectal ultrasonography. Prostatic calcification correlated with symptoms (National Institutes of Health chronic prostatitis symptom index score), examination findings, and culture results. The variables were compared using the Student t test, Wilcoxon unpaired test, or chi-square test.

RESULTS

The 47 men who had undergone transrectal ultrasonography had symptoms identical to those who had not but were older (range 46.1 to 41.6 years, P = 0.02) and had had symptoms longer (median 60 versus 12 months, P = 0.0001). Of the 47 patients, 22 (47%) had significant calcification. The symptoms with or without calcification were identical (chronic prostatitis symptom score 23.7 versus 23.9). Men with calcification had had symptoms longer (median 84 versus 27 months, P = 0.05) but were similar in age (49 versus 45 years, P = 0.21) and had a similar prostate size (21.7 cm3 for both groups). Men with calcification were less likely to have pelvic floor tenderness (50% versus 85%, P = 0.03) but were more likely to have bacteria in the prostatic fluid (P = 0.05) and had a higher median white blood cell count (3.5 versus 0 white blood cells per high power field, P = 0.058).

CONCLUSIONS

Prostatic calcification is common in patients with CPPS and is associated with greater inflammation, bacterial colonization, and symptom duration. Pelvic floor spasm is more common in patients without calcification. This might be an important parameter with which to stratify clinical trials.

Effects of pollen extract preparation Prostat/Poltit on lower urinary tract symptoms in patients with chronic nonbacterial prostatitis/chronic pelvic pain syndrome: a randomized, double-blind, placebo-controlled study

OBJECTIVES

To assess the efficacy and safety of the pollen extract preparation Prostat/Poltit in the treatment of patients with chronic nonbacterial prostatitis/chronic pelvic pain syndrome.

METHODS

In a double-blind study, 60 patients between 20 and 55 years old with chronic nonbacterial prostatitis/chronic pelvic pain syndrome were randomized to receive Prostat/Poltit or placebo for 6 months. The patients had been symptomatic for more than 6 months without response to any given therapy. The patients were evaluated at the start of the treatment and after 6 months of treatment with the help of a symptom questionnaire covering the symptoms in seven pain locations, five voiding symptoms, three storage symptoms, and four sex-related symptoms.

RESULTS

The overall clinical evaluation of the treatment result showed that after treatment for 6 months more patients taking Prostat/Poltit were cured or improved than patients taking placebo. No adverse reactions to the treatment were found.

CONCLUSIONS

Prostat/Poltit is superior to placebo in providing symptomatic relief in men with chronic nonbacterial prostatitis/chronic pelvic pain syndrome.

Traditional therapy for chronic pelvic pain does not work: what do we do now?

The dilemma of managing patients with chronic pelvic pain syndromes continues to frustrate physicians confronted with these complaints. Multiple diagnoses traditionally label this condition in men and women and, typically, implicate a pelvic-organ system when, in fact, very little objective evidence for a pathophysiologic process exists. Traditional therapies, consisting of antibiotics, anti-inflammatories, and muscle relaxants, simply do not work, and their lack of efficacy compared with placebo has been documented by randomized clinical trials in the US that were sponsored by the NIH. What do we do now? This review article attempts to describe the clinical efforts of several investigators and to put their patients' outcomes in perspective, and thereby suggest alternative therapies to help these patients.

Preliminary experience with a terpene mixture versus ibuprofen for treatment of category III chronic prostatitis/chronic pelvic pain syndrome

To evaluate the efficacy of a terpene mixture (rowatinex) compared to ibuprofen, patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) were randomly selected to either receive rowatinex 200 mg t.i.d. or ibuprofen 600 mg t.i.d. After a 6-week treatment, the decrease in the mean total NIH-CPSI score was significant in both groups from 21.4 to 15.3, (6.1 (p < 0.01) and from 21.2 to 16.8, (4.4 (p = 0.04) in the rowatinex and ibuprofen group, respectively. The rate of definite improvement as defined as 25% improvement in the total score was superior (p = 0.04) in the rowatinex group (68%) versus the ibuprofen group (40%). Judging from these results, rowatinex gave significant symptomatic relief and may be of benefit for many men diagnosed with CP/CPPS. Further, including the placebo-controlled studies are necessary to define its role in the management of this difficult to treat disease.

The overlapping lower urinary tract symptoms of benign prostatic hyperplasia and prostatitis

PURPOSE OF REVIEW

To investigate the relationship, diagnosis and treatment of the overlapping lower urinary tract symptoms experienced by men diagnosed with benign prostatic hyperplasia and prostatitis.

RECENT FINDINGS

Recent studies have clearly shown that men can suffer from both benign prostatic hyperplasia and prostatitis. Approximately 5-20% of men diagnosed with benign prostatic hyperplasia suffer from prostatitis-like symptoms, while over one third of men diagnosed with benign prostatic hyperplasia have had a diagnosis of prostatitis in the past. Differentiation between these two symptom-based medical conditions can be difficult because of overlapping symptoms, but pain clearly identifies those patients with chronic prostatitis. Treatment for men with co-occurring benign prostatic hyperplasia and prostatitis may include alpha-blockers, 5alpha-reductase inhibitors and phytotherapies (saw palmetto and bee pollen extract), with evidence clearly showing the benefits of alpha-blocker therapy.

SUMMARY

Benign prostatic hyperplasia and chronic prostatitis are a common cause of lower urinary tract symptoms and frequently co-occur in older men. The best treatment for men with lower urinary tract symptoms associated with both benign prostatic hyperplasia and prostatitis is alpha-blockers.

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.

Saw palmetto and finasteride in the treatment of category-III prostatitis/chronic pelvic pain syndrome

Chronic nonbacterial prostatitis/chronic pelvic pain syndrome is a common entity for which a standardized management has not been established. Patients often have a significant symptom complex and impact on quality of life, but very little is known about the efficacy of second- and third-line treatments, such as the use of herbal supplements. Many treatments studied in recent literature include antibiotics, alpha-blockade, anti-inflammatory agents, and cognitive behavioral interventions such as biofeedback and psychotherapy.

Anti-nanobacterial therapy for men with chronic prostatitis/chronic pelvic pain syndrome and prostatic stones: preliminary experience

PURPOSE

Category III chronic prostatitis/chronic pelvic pain syndrome (CPPS) is a common debilitating condition of unclear etiology. Patients often have prostatic calcifications but a link to symptoms is controversial. Nanobacteria are implicated in stone formation in the urinary tract and, therefore, therapy to eliminate nanobacteria and the stones that they produce might have an impact on CPPS symptoms.

MATERIALS AND METHODS

A total of 16 men with recalcitrant CPPS refractory to multiple prior therapies were treated with comET (Nanobac Life Sciences, Tampa, Florida), which consists of 500 mg tetracycline, a proprietary nutraceutical and an ethylenediaminetetraacetic acid suppository daily. The National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI), transrectal ultrasound, and blood and urine tests for nanobacterial antigen were performed at the start and conclusion of 3 months of therapy. One patient was lost to followup.

RESULTS

Mean NIH-CPSI total score +/- SD decreased from 25.7 +/- 1.6 to 13.7 +/- 2.0 (p <0.0001). Significant improvement was seen in each subscore domain. A total of 12 patients (80%) had at least 25% improvement on NIH-CPSI and 8 (53%) had at least 50% improvement. Nanobacterial antigen or antibody was found in 60% of serum and 40% of urine samples. In 10 patients who underwent transrectal ultrasound after therapy prostatic stones were decreased in size or resolved in 50%.

CONCLUSIONS

Therapy designed to eliminate nanobacteria resulted in significant improvement in the symptoms of recalcitrant CPPS in the majority of men, whether due to the treatment of stone producing nanobacteria or through some other mechanism. Prospective placebo controlled trials are warranted.

[Chronic prostatitis. Chronic pelvic pain syndrome]

The symptom complex called prostatitis represents a multifactorial problem of unclear etiology. Standardized diagnostic and therapeutic approaches do not exist. Controlled studies which fulfil evidence-based medical criteria are missing. A review of the currently available literature leads to the conclusion that a multimodal therapy concept should be developed and examined.

Etiology and management of chronic pelvic pain syndrome in men

Prostatitis results in >2 million physician office visits annually. Characterized by pelvic pain and voiding symptoms, chronic pelvic pain syndrome (CPPS) is poorly defined. The Chronic Prostatitis Collaborative Research Network (CPCRN) has put forward a uniform set of classifications for chronic prostatitis based on pain being the primary symptom. The CPCRN has also created a valid instrument for measuring symptoms: the Chronic Prostatitis Symptom Index. After nonbacterial prostatitis has been diagnosed, treatment of patients should be individualized. The condition may be caused by bladder, prostate, pelvic side wall, or seminal vesicle pathology. In addition to currently used treatments, several new therapies are being investigated after promising pilot studies. Despite the multiple approaches to management of CPPS, no hard and fast guidelines have been developed. This review provides an overview of assessment techniques and management options for men with CPPS.

A prospective, 1-year trial using saw palmetto versus finasteride in the treatment of category III prostatitis/chronic pelvic pain syndrome

PURPOSE

This study was designed to assess the safety and efficacy of saw palmetto or finasteride in men with category III prostatitis/chronic pelvic pain syndrome (CP/CPPS).

MATERIALS AND METHODS

A prospective, randomized, open label, 1-year study was designed to assess the safety and efficacy of saw palmetto and finasteride in the treatment of men diagnosed with CP/CPPS. Patients were randomized to finasteride (5 mg once daily) or saw palmetto (325 mg daily) for 1 year. Patients were evaluated using the National Institutes of Health Chronic Prostatitis Symptom Index, individual domains (pain, urinary symptoms, quality of life and mean pain score) and the American Urological Association Symptom Score at baseline, 3, 6 and 12 months.

RESULTS

A total of 64 consecutive men 24 to 58 years old (mean age 43.2) with a diagnosis of CP/CPPS were equally randomized to the 2 treatment arms. All 64 men had previously received antibiotics (duration of 3 to 93 weeks), 52 (82%) had been on alpha-blockade. There were 61, 57 and 56 patients evaluable at 3, 6 and 12 months, respectively. At 1 year mean total National Institutes of Health Chronic Prostatitis Symptom Index score decreased from 23.9 to 18.1 in the finasteride group (p <0.003), and from 24.7 to 24.6 in the saw palmetto arm (p = 0.41). In the finasteride arm the quality of life and pain domains were significantly improved at 1 year; however, urination was not. Adverse events included headache (3 cases) in the saw palmetto group and decreased libido (2 cases) in the finasteride group. At the end of the trial 13 of 32 (41%) and 21 of 32 (66%) opted to continue saw palmetto and finasteride, respectively.

CONCLUSIONS

CP/CPPS treated with saw palmetto had no appreciable long-term improvement. In contrast, patients treated with finasteride had significant and durable improvement in all various parameters except voiding. Further studies are warranted to ascertain the mechanism and reproducibility of these effects in a placebo controlled trial.

Phytomedicines for the prostate

Phytomedicines are becoming more popular all over the world. Prostate cancer patients and those with benign prostatic hyperplasia are increasingly exploring the use of complementary alternative medicine especially due to the risk of mortality and long-term morbidity associated with surgical procedures. The incidences of prostate diseases are continually rising and the effect of phytomedicines already tested do provide relief, are well comparable with that of traditional forms of treatment. This paper reviews the phytomedicines used in Africa, Western countries and China as a treatment of benign prostatic hyperplasia, prostatitis and prostate cancer. Herbals which hold potential promise are mentioned, although much research is still required.

Comparison of Saw Palmetto (extract and whole berry) and Cernitin on prostate growth in rats

Pharmaceuticals such as finasteride and alpha blockers are used to treat symptoms of benign prostatic hyperplasia (BPH) and are known to cause severe adverse reactions. Accordingly, a search for safer, natural products has been undertaken. Two natural agents (nutraceuticals) have come under recent scrutiny; because natural products, in general, often have evidence of long-term safety. The present study compares the in vivo effects on androgen-induced prostatic enlargement in rats of two nutraceuticals--the widely recognized Saw Palmetto (Serenoa repens) and the less well-known Cernitin (defined pollen extract). Non-castrated rats, had a mean prostate weight of 124 mg +/- 8.8 (S.E.M.) compared to the 24.5 mg +/- 1.9 (S.E.M.) of the castrated rat followed under the same regimen (p < 0.01). When castrated rats were given testosterone, the mass increased significantly to 250.0 mg +/- 31.7 (S.E.M.) (p < 0.01). In the five remaining groups, castrated rats receiving testosterone were given finasteride, an extract of Saw Palmetto, crushed whole berry derived from Saw Palmetto fruit, a water soluble and fat soluble extract of Cernitin or a combination of the Saw Palmetto extract and Cernitin. All treatments decreased the size of the prostate to roughly the same size as in the non-castrated rats, a size that was significantly smaller than castrated rats treated with testosterone in the same manner (p < 0.01). A second study examining non-castrated rats treated with very high doses of testosterone showed similar results. In both studies, the nutraceuticals generally decreased body weight. In conclusion, these studies show the ability of Saw Palmetto (whole berry and extract) and Cernitin to influence prostatic hyperplasia via effects on androgen metabolism.

Long-term results of multimodal therapy for chronic prostatitis/chronic pelvic pain syndrome

PURPOSE

Chronic prostatitis/chronic pelvic pain syndrome is a prevalent and multifactorial condition. Many patients have the condition for years despite conventional therapies. We assess the outcomes of multimodal therapy in patients with long-standing chronic prostatitis/chronic pelvic pain syndrome.

MATERIALS AND METHODS

A total of 53 patients with chronic prostatitis treated at our clinic with a minimum followup of 6 months were assessed by the National Institutes of Health-Chronic Prostatitis Symptom Index and by a global assessment score. Treatments included antibiotics, prostatic massage, anti-inflammatory phytotherapy, alpha-blockers and neuromuscular agents.

RESULTS

Mean age patient was 45 years and median symptom history was 3.5 years. Based on localizing cultures, and microscopy of urine and prostatic fluid 13% of the cases were category II, 41% were category IIIa and 46% were category IIIb. Mean followup from the last visit was 417 days (range 185 to 1,247). Mean changes +/- SE from the initial to the final score on the National Institutes of Health-Chronic Prostatitis Symptom Index were 10.4 +/- 3.3 to 5.9 +/- 4.4 for pain, 4.2 +/- 2.9 to 2.0 +/- 2.7 for urinary, 8.2 +/- 2.9 to 4.7 +/- 3.4 for quality of life and 22.7 +/- 6.6 to 13.2 +/- 9.5 for total score (p <0.0001). Based on a global subjective assessment 43 of the patients (80%) were better, 8 were the same and 3 were worse. At final assessment 39% of the patients were on no therapy, 22% were on an alpha-blocker, 37% were on quercetin, 13% were on neuromuscular agents and 9% were on antibiotics.

CONCLUSIONS

An approach using stepwise therapy with antibiotics, anti-inflammatories and neuromuscular agents can be successful in the majority of patients with long-standing chronic prostatitis.

Randomized trial of a combination of natural products (cernitin, saw palmetto, B-sitosterol, vitamin E) on symptoms of benign prostatic hyperplasia (BPH)

Because benign prostatic hyperplasia (BPH) is relatively common, it is important to discover safe and effective means to treat this often debilitating perturbation. Accordingly, we examined the effectiveness of a combination of natural products (cernitin, saw palmetto, B-sitosterol, vitamin E) in treating symptoms of BPH. We undertook a randomized, placebo-controlled, double-blind study. Patients were enrolled from 3 urological practices in the USA. 144 subjects were randomized for study. 17 subjects eventually withdrew, leaving 70 patients in the test group and 57 in the placebo group to complete the study. Inclusion criteria consisted of a diagnosis of BPH, no evidence of cancer, and a maximal urinary flow rate between 5 and 15 ml/second. Patients received either placebo or the combined natural products for 3 months. Evaluations were performed via the American Urological Association (AUA) Symptom Index score, urinary flow rate, PSA measurement, and residual bladder volume. Nocturia showed a markedly significant decrease in severity in patients receiving the combined natural products compared to those taking placebo (p < 0.001). Daytime frequency was also lessened significantly (p < 0.04). When the average individual total AUA Symptom Index score in the test group was compared to that in the placebo group at the end of the study, the difference proved highly significant (p < 0.014). PSA measurements, maximal and average urinary flow rates, and residual volumes showed no statistically significant differences. When taken for 3 months, a combination of natural products (cernitin, saw palmetto, B-sitosterol, vitamin E) compared to placebo can significantly lessen nocturia and frequency and diminish overall symptomatology of BPH as indicated by an improvement in the total AUA Symptom Index score. The combination of natural products caused no significant adverse side effects.

Overview summary statement. Diagnosis and management of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS)

Members of the Chronic Prostatitis Collaborative Research Network (CPCRN) met in a 1-day symposium to review recent findings and to debate unanswered issues in the diagnosis and management of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). The meeting was focused on producing an overview summary statement that would, as nearly as possible, represent the consensus views of the attendees. As discussed below, the participants agreed that a history, physical examination, and urinalysis/urine culture are mandatory for the evaluation of all patients presenting with CP/CPPS, with other assessments categorized as recommended or optional, depending on the history and physical findings. Observations and suggestions regarding first- and second-line therapies are also offered, with the recognition that randomized, placebo-controlled trials to guide selection of therapies for chronic nonbacterial prostatitis are currently lacking.

Phytotherapy in chronic prostatitis

Chronic prostatitis is a very common condition that is poorly understood and has a significant impact on quality of life. Given the lack of proven efficacy of conventional therapies, such as antibiotics, it is not surprising that patients have turned with increasing frequency to phytotherapy and other alternative treatments. Although alternative therapies are plentiful, few have been subjected to scientific scrutiny and prospective controlled clinical trials. This review will cover phytotherapies commonly used in prostatitis patients and focus in detail on those with published data. These treatments include zinc, cernilton (bee pollen), quercetin, and saw palmetto. Although many of these therapies appear promising in small preliminary studies, phytotherapy requires the same scientific criteria for validation and acceptance as do conventional medical therapies.

Demographic and clinical characteristics of men with chronic prostatitis: the national institutes of health chronic prostatitis cohort study

PURPOSE

We describe the study design of the National Institutes of Health Chronic Prostatitis Cohort (CPC) study characterizing men with chronic prostatitis/the chronic pelvic pain syndrome.

MATERIALS AND METHODS

All 488 men screened into the CPC study before close of recruitment on August 22, 2001 were selected for analysis. The National Institutes of Health Chronic Prostatitis Symptom Index, including subscores, was used to measure symptoms. A comprehensive history, physical examination and demographic profile were obtained from each participant. Generalized Mantel-Haenszel procedures were used to investigate baseline associations between selected factors and symptoms.

RESULTS

Chronic prostatitis/chronic pelvic pain syndrome is a chronic syndrome affecting men over a wide age range. The majority of CPC study participants are white, well educated and affluent. However, lower education, lower income and unemployment were associated with more severe symptoms. Patients most frequently reported pain in the perineum and tenderness in the prostate. The highest self-reported diseases were genitourinary (55%), allergies (53%), neurological (40%) and hematopoietic, lymphatic or infectious (40%). This disease has a significant negative impact on mental and physical domains of quality of life. Almost all patients (95%) reported antimicrobial drug use. Of these 488 participants 280 (57%) reported the previous or current use of 5 or more categories of prostatitis related treatments.

CONCLUSIONS

Chronic prostatitis/chronic pelvic pain syndrome is a multifactorial problem affecting men of all ages and demographics. Patients with the chronic pelvic pain syndrome have dismal quality of life and many have benefited only minimally from empirical, goal directed therapy. Long-term followup of this cohort may answer important questions on the natural treated history of this syndrome.
