The role of Chlamydia trachomatis in prostatitis

Ascending chlamydial infections have been thought to be an infective cause of prostatitis for the last three decades. Unfortunately, the definitive association between isolation of an infective agent and its prostatic origin is limited by various factors, although modern techniques of molecular biology for identification of the microorganisms are available. Two major problems are: (1) diagnostic material passing the urethra may reflect only urethral contamination, (2) prostatic biopsy specimens from the gland may also contain urethral material. The ejaculate has the same limitations, and an ideal test for detection of Chlamydia species in ejaculate specimens is not available yet. Investigations for local chlamydial IgA-antibodies may be useful; the overlap with Chlamydia pneumoniae and Chlamydia psittaci means a clear differentiation on an type-specific basis is necessary, which is normally provided by the 'elaborate' microimmunofluorescence test. Modern p-ELISAs using major outer membrane protein parts as antigens may deliver identical results in the future. In the follow-up of standardized prostatitis patients, a combination of such urological tests in EPS and seminal plasma combined with genital chlamydial DNA material, may further elucidate the chlamydial aetiology of prostate infection.

Primary care and urology patients with the male pelvic pain syndrome: symptoms and quality of life

PURPOSE

We assessed symptoms and health related quality of life in men who received prostatitis-prostatodynia diagnoses at primary care and urology visits, and compared those in whom pain-discomfort had versus had not resolved approximately 1 month later.

MATERIALS AND METHODS

Telephone interviews were done with 357 men an average of 1 month after a prostatitis-prostatodynia diagnosis was made at a health maintenance organization visit. The interview included the National Institutes of Health Chronic Prostatitis Symptom Index, and pain and health related quality of life measures.

RESULTS

The most common pain location was the pubic-bladder area. Mean scores on most health related quality of life measures were below average, and higher pelvic pain and urinary symptom scores were associated with worse quality of life. This episode of pelvic pain was the first lifetime episode in fewer urology (22%) than primary care (38%) patients (p = 0.02). Urology patients had longer symptom episodes (p = 0.000), more days with pain in the last month (p = 0.002) and higher National Institutes of Health Chronic Prostatitis Symptom Index pain scores (p = 0.002). Men with pain in the testicles, penis or between the rectum and testicles at the visit, and with longer symptom duration before the visit were significantly more likely to have continued pain between the visit and interview.

CONCLUSIONS

Pelvic pain is often a persistent, recurrent condition that can have a significant negative impact on quality of life. The average symptom severity in men with pelvic pain in primary care and urology settings is lower than that in tertiary care samples.

Management of chronic prostatitis-chronic pelvic pain syndrome

Although the neurobiologic basis of CPPSs in men remains unclear, therapeutic interventions should continue to be improved. Invasive or destructive modalities should be avoided when possible. Electrical neuromodulation techniques seem to be a promising, among other multimodal approaches. Physicians must learn from patients in attempt to relieve symptoms.

[The treatment of method of regulating qi by alleviation of mental depress in chronic abacteria prostatitis]

OBJECTIVES

To evaluate the efficacy of method of regulating qi by alleviation of mental depress for chronic abacteria prostatitis (CAP).

METHODS

From Aug. 2000 to Dec. 2000, 60 patients underwent TCM treatment with either method of regulating qi by alleviation of mental depress (31 cases) or promoting blood circulation (29 cases).

RESULTS

The marked rate and effective rate were 83.86%, 93.55% in treatment group, and 65.52%, 93.10% in the control group, respectively. The marked rate in treatment group was higher than that of control group. Scores of NIH-CPSI were more decreased in treatment group than that in control group(P < 0.05). The quality of life improved significantly in treatment group than that in control group (P < 0.05).

CONCLUSIONS

Method of regulating qi by alleviation of mental depress had its advantage over methods of promoting blood circulation for CAP and was an effective treatment modality for CAP.

Understanding chronic pelvic pain syndrome

Patients with non-inflammatory chronic pelvic pain syndrome, the largest group of prostatitis patients according to the US National Institute of Diabetes and Digestive and Kidney Diseases classification, are characterized by the absence of objective findings. Nothing thus links the symptoms of this disease to the prostate or other male organs in particular. For this reason, observations on interstitial cystitis in women are of interest to understand the chronic pelvic pain syndrome. New information from studies on the inflammatory response in expressed prostatic secretion in patients with chronic pelvic pain syndrome and in bladder tissue from patients with interstitial cystitis indicates that complex systems on the cytokine gene expression level may be operating in these diseases. Research findings point to a common denominator at the level of molecular biology that might explain how the symptoms of chronic pelvic pain syndrome and interstitial cystitis can be precipitated by pathogens, inflammatory reactions and even neurological mechanisms. The initial clinical trial reports of drugs that modulate the inflammatory response in interstitial cystitis are met with great interest.

Influence of environmental factors on chronic prostatitis-like symptoms in young men: results of a community-based survey

OBJECTIVES

To investigate the influence of environmental factors on chronic prostatitis-like symptoms among young men in a community.

METHODS

Of 28,841 men aged 20 years dwelling in the community, a total of 16,321 men (response rate 56.6%) were included in this study. The National Institutes of Health Chronic Prostatitis Symptom Index was used to identify men with chronic prostatitis-like symptoms. The questionnaire also queried sociodemographic characteristics. The Korean Meteorological Administration provided information on the weather of the community. We determined the risk factors of chronic prostatitis-like symptoms among these environmental factors using univariate and multivariate analyses.

RESULTS

Six percent of the men were identified as having significant prostatitis-like symptoms (perineal and/or ejaculatory pain and a total pain score of 4 or greater). The univariate logistic regression analysis indicated that education level, average duration of sunlight, and average temperature were risk factors for chronic prostatitis-like symptoms. As these variables increased, the scores of chronic prostatitis-like symptoms decreased. In the multivariate model used, the likelihood of chronic prostatitis-like symptoms varied by the final educational level, with middle school and high school graduates having 1.8 and 1.4-fold higher odds, respectively, than men attending college. In the same model, the average duration of sunlight was also an independent risk factor of chronic prostatitis-like symptoms (odds ratio 0.85; 95% confidence interval 0.77 to 0.95; P = 0.003), but the average temperature lost statistical significance.

CONCLUSIONS

Our findings suggest that the community-based prevalence of chronic prostatitis-like symptoms may be high in young men. Higher education and a longer time in sunlight were associated with a decreased likelihood of chronic prostatitis-like symptoms.

Preneoplastic prostate lesions: an opportunity for prostate cancer prevention

Environmental factors, especially the diet, play a prominent role in the epidemic of prostate cancer (PCA), in the United States. Many candidate dietary components have been proposed to influence human prostatic carcinogenesis, including fat, calories, fruits and vegetables, anti-oxidants, and various micronutrients, but the specific roles dietary agents play in promoting or preventing PCA remain controversial. We have collected evidence to suggest that GSTP1, the gene encoding the pi-class glutathione S-transferase (GST), may serve a "caretaker" function for prostatic cells. Although GSTP1 can be detected in normal prostatic epithelium, in almost all PCA cases, PCA cells fail to express GSTP1 polypeptides, and lack of GSTP1 expression most often appears to be the result of somatic "CpG island" DNA methylation changes. Loss of GSTP1 function also appears to be characteristic of prostatic epithelial neoplasia (PIN) lesions, thought to represent PCA precursors. We have recently learned that a new candidate early PCA precursor lesion, proliferative inflammatory atrophy (PIA), characterized by proliferating prostatic cells juxtaposed to inflammatory cells, contains epithelial cells that express high levels of GSTP1. These findings have formed the basis for a new model of prostatic carcinogenesis, in which prostatic cells in PIA lesions, subjected to a barrage of inflammatory oxidants, induce GSTP1 expression as a defense against oxidative genome damage. When cells with defective GSTP1 genes appear amongst the PIA cells, such cells become vulnerable to oxidants and electrophiles that inflict genome damage that tends to promote neoplastic transformation to PIN and PCA cells. Subsequently, PIN and PCA cells with defective GSTPI genes remain vulnerable to similar stresses tending to promote malignant progression. This new model for prostatic carcinogenesis has implications for the design of new prostate cancer prevention strategies. Rational prevention approaches might include: (i) restoration of GSTPI expression via treatment with inhibitors of CpG methylation, (ii) compensation for inadequate GSTPI activity via treatment with inducers of general GST activity, and (iii) abrogation of genome-damaging stresses via avoidance of exogenous carcinogens and/or reduction of endogenous carcinogenic (particularly oxidant) stresses.

Hemospermia: review of the management with 5 years follow-up

OBJECTIVE

To review our experience with hemospermia and a long term follow-up.

MATERIAL AND METHOD

Medical records of patients with hemospermia treated at the Division of Urology, Ramathibodi Hospital between 1993 and 1995 were reviewed. Clinical presentation, investigation, diagnosis, treatment, outcomes and long term follow-up were noted.

RESULTS

Sixty-eight patients were found and completed follow-up to 5 years. The mean age was 40 years (range 28-62). Physical examination including DRE and urine examinations were done in all of the cases. Special investigations such as PSA, TRUS, IVP and cystourethroscopy were performed in selected cases. Prostatitis was found in 27.9 per cent, tuberculosis in 4.4 per cent, sexually related causes in 5.8 per cent and idiopathic in 61 per cent No malignancy was found in this study. Hypertension was found in 7.3 per cent of the patients. Thirty-two per cent had recurrent episodes of hemospermia. Specific treatment was used only for prostatitis and tuberculosis. No specific treatment was used for the idiopathic group.

CONCLUSIONS

Hemospermia is a benign condition. Most of the causes were from idiopathic and inflammation. Only simple investigation was needed and treatment was recommended depending on the diagnosis and no specific treatment was needed for idiopathic cause.

Effects of treatment with carnitines in infertile patients with prostato-vesiculo-epididymitis

BACKGROUND

We have recently shown that patients with prostato-vesiculo-epididymitis (PVE) have a greater reactive oxygen species (ROS) overproduction than patients with prostatitis or prostato-vesiculitis. Since this biochemical stress persists even after treatment with antimicrobials, it may relate to an imbalance between pro- and anti-oxidant factors at the epididymal level.

METHODS

To evaluate the effects of antioxidant treatment of patients with PVE, whether in the presence or absence of pro-oxidant factors, abacterial PVE infertile patients with normal (<1x10(6)/ml, group A, n = 34) or abnormal (>1x10(6)/ml, group B, n = 20) seminal white blood cell (WBC) concentrations received carnitines (L-carnitine 1 g and acetyl-carnitine 0.5 g twice/day) for 3 months followed by a wash-out period of 3 months. Semen parameters, ROS production and pregnancy outcome were evaluated before, during and following carnitine treatment.

RESULTS

Carnitines increased sperm forward motility and viability in group A patients. This was associated with a significant reduction in ROS production which persisted during wash-out. Carnitines increased only the percentage of viable spermatozoa in group B patients. Within 3 months after the discontinuation of carnitines, the rate of spontaneous pregnancy in group A patients was significantly higher than that of group B patients, being 11.7% (4/34) compared with 0%.

CONCLUSION

These results indicate that carnitines are only an effective treatment in patients with abacterial PVE and elevated ROS production when seminal WBC concentration is normal.

Variability of the symptoms of chronic abacterial prostatitis/chronic pelvic pain syndrome during intermittent therapy with rectal prednisolone foam for ulcerative colitis

We describe the response of symptoms of chronic abacterial prostatitis/chronic pelvic pain syndrome (CAP/PPS) in a man treated with rectal prednisolone for concomitant ulcerative colitis. The temporal relationship of the symptoms of CAP/PPS to starting and stopping the topical corticosteroid over 2 treatment cycles lends further anecdotal support to our hypothesis that treatment of the immune-mediated response in this chronic condition has a beneficial effect upon symptomatic outcome.

Cytotoxic necrotizing factor type 1-positive Escherichia coli causes increased inflammation and tissue damage to the prostate in a rat prostatitis model

Infection of rat prostates with cytotoxic necrotizing factor type 1 (CNF1)-positive uropathogenic Escherichia coli caused more inflammation-mediated morphological and histological tissue damage than did infection with isogenic CNF1-negative mutants. These striking differences occurred despite the finding that bacterial counts for the strain pairs were indistinguishable. We conclude that CNF1 contributes to E. coli virulence in a model of acute prostatitis. To our knowledge, the results of this study provide the first demonstration of a role for any uropathogenic E. coli virulence factor in acute prostatitis.

[A system of comprehensive assessment of symptoms in chronic prostatitis (CAS-XII)]

The system proposed for overall assessment of symptoms in chronic prostatitis was applied in the assessment of 75 patients. The system facilitates detection and analysis of the complaints, quantitates the disease symptoms, provides overall objective characteristics of all the multiplicity of clinical manifestations of chronic prostatitis in each patient by means of digital order. The system is rather effective for dynamic control of the patients' condition and treatment efficacy.

[Rehabilitation of patients with chronic prostatitis and reproductive dysfunction in a special hospital]

Combined aftercare with mud applications, sinusoidal modulated currents (SMC) and UV radiation of autoblood was compared to conventional drug therapy in 56 and 30 patients, respectively, having chronic prostatitis with reproductive dysfunction. It was found that the combined aftercare raises the treatment efficiency due to a favourable effect on the immune system, inflammation in the prostate and spermatogenesis. It also promotes long-term remission.

[Effect of radio wave-induced hyperthermia on microflora of the prostate in the treatment of prostatitis associated with infertility]

The influence of hyperthermia induced by radiowaves on the microflora of the prostate in cases of male sterility was studied. The use of hyperthermia was shown to produce a stable decrease in bacteriospermia and the persistence potential of bacteria isolated from sperm. Hyperthermia produced a bactericidal effect not only on microorganisms contained in sperm but also on the microflora of prostatic tissues 1 cm deep. The study gave grounds for treating male sterility with the use of hyperthermia induced by radiowaves and a subsequent course of antibiotics to achieve the stable decrease of bacteriospermia and the restoration of the reproductive function.

The male chronic pelvic pain syndrome

Suffering chronic pain is a common and debilitating problem that significantly impairs the quality of life of affected patients. Because we continue to struggle with chronic pelvic pain disorders both diagnostically and therapeutically, a neuro-behavioral perspective should be used in an attempt to explain pathways and neurophysiological mechanisms, and to improve diagnostics and treatment of male pelvic pain. First, however, malignant and acute/chronic bacterial disease has to be excluded as a cause of chronic pain in every single case. Then diagnostic approaches should screen for lower urinary tract dysfunction, pelvic floor functional disorders, and disturbed reflex integrity within the pelvic area. Treatment approaches for the male chronic pelvic pain syndrome could be divided into causal and symptomatic. Causal treatment approaches try to influence basic mechanisms generating and supporting chronic pain. In most cases a symptomatic approach is needed to relieve pain immediately. Because generally accepted treatment protocols and studies are missing, the following approach in the individual patient is recommended: (1) symptomatic treatment for immediate pain relief, (2) diagnostic work-up, (3) causal treatment trial.

Predictors of patient response to antibiotic therapy for the chronic prostatitis/chronic pelvic pain syndrome: a prospective multicenter clinical trial

PURPOSE

To our knowledge antibiotics are the most popular choice of therapy for all categories of the chronic prostatitis/chronic pelvic pain syndrome. We determine if culture, leukocyte and/or antibody status of prostate specific specimens predicts patient response to antibiotic therapy.

MATERIALS AND METHODS

Patients clinically diagnosed with the chronic prostatitis/chronic pelvic pain syndrome according to the National Institutes of Health (NIH) definition had a lower urinary tract evaluation that included standard microscopy and culture of prostate specific specimens, and determination of the ratio of voided bladder 3 and voided bladder 2 antibody levels against a panel of identified prostate pathogens (enzyme linked immunosorbent assay methodology). Symptom evaluation consisted of the NIH chronic prostatitis symptom index (derived) pain scale 0 to 21, symptom severity index scale 0 to 100, symptom frequency questionnaire scale 0 to 50 and quality of life scale 0 to 6. Patients were stratified according to microscopy, culture and immune status, were treated with 12 weeks of ofloxacin, and were assessed at 4, 12 and 24 weeks with symptom scores as well as global assessments.

RESULTS

Based on leukocyte and culture results, 102 evaluable patients were stratified into categories II (14%), IIIA (48%) and IIIB (38%) of the chronic prostatitis/chronic pelvic pain syndrome. Of the cases 23% were categorized as antibody positive and 77% as antibody negative. Average age was 42 +/- 10 years and 92% of patients were white. Of the patients 57% believed that they had moderate to marked improvement. All categories of the chronic prostatitis/chronic pelvic pain syndrome and patients in whom antibody was positive or negative had significant improvement in the NIH chronic prostatitis symptom index, symptom severity index, symptom frequency questionnaire and quality of life scores compared with baseline (p <0.001). There was no significant difference in patient response to the stratification based on culture, leukocyte, that is categories II, IIIA and IIIB had same beneficial response, or antibody status.

CONCLUSIONS

Culture, leukocyte and antibody status of prostate specific specimens does not predict antibiotic response in patients with the chronic prostatitis/chronic pelvic pain syndrome. The perceived beneficial effect of antibiotics needs to be evaluated in a randomized placebo controlled trial.

The prevalence of chronic prostatitis-like symptoms in young men: a community-based survey

We surveyed the prevalence of chronic prostatitis-like symptoms in young men using the National Institutes of Health (NIH) Chronic Prostatitis Symptom Index (CPSI) and determined the clinical validity of the NIH-CPSI among men in the community. Of 29,017 men aged 20 years dwelling in the community, 8,705 men were randomly selected at a 30.0% sampling fraction and a total of 6,940 men (a response rate 79.7%) completed a self-administered questionnaire. Six percent reported having pain or discomfort in more than one area . About 5% did not feel that the bladder emptied fully after urinating more than 1 time in 5 and 10.5% had to urinate again within 2 h more than 1 time in 5. As the scores for pain or discomfort increased, those for urinary symptoms and impact on quality of life increased (P < 0.001; Armitage test). As the scores for urinary symptoms increased, those for pain or discomfort and impact on quality of life also increased (P < 0.001; Armitage test). The community-based prevalence of chronic prostatitis-like symptoms were found to be high in young men as well as in older men. Our findings indicate that men with pain or urinary symptoms experience a negative impact on their quality of life and the NIH-CPSI provides a valid measure for the general population.

Prostatitis. Work-up and treatment of men with telltale symptoms

Prostatitis describes a spectrum of disorders involving inflammation of the prostate gland. This common yet poorly understood condition produces an array of symptoms, the most common of which are urinary obstruction, perineal pain, and ejaculatory complications. Although several theories have been proposed regarding its etiology, the exact mechanism of disease remains elusive. Definitive diagnosis can be hampered by a somewhat cumbersome testing procedure, but symptomology tends to be a reliable guide for treatment. Although treatment with antibiotics often fails, the fluoroquinolones are among the most effective agents for symptom management. Other interventions that may be appropriate include alpha-1-adrenergic blockers, a 5-alpha reductase inhibitor, or surgery. Chronic prostatitis may result in repeated urinary tract infections and chronic pain syndromes.

[Antioxidant therapeutic efficiency after the use of carnitine in infertile patients with bacterial or non bacterial prostato-vesiculo-epididymitis]

OBJECTIVE

In the male genital tract, reactive oxygen species (ROS) overproduction generated by infiltrating WBC or spermatozoa is one of the major causes of defective sperm function. Recently, we demonstrated that prostato-vesiculo-epididymitis (PVE) is the male accessory gland infection more crucial for the establishment of this cellular (sperm and/or WBC oxidative) response. This biochemical stress is due to an imbalance of pro and antioxidants factors and persists even after treatment with antimicrobials. Thus, the antioxidative properties of Carnitines (in terms of combined "Carnitine-Acetil-Carnitine" system) have currently found more attention as part of antimicrobial therapies. In this study, we compared which antioxidative strategy was more beneficial for the treatment of PVE.

MATERIALS AND METHODS

We selected two groups of infertile patients. One group consisted of 55 abacterial PVE patients (mean age 34 yrs, range 27-40) (group A); the other included other 35 bacterial PVE patients (mean age 35 yrs, range 28-38) (group B). Each group was randomly subdivided into the following treatment subsets: 1) A1 (n = 14) and B1 (n = 23) subsets received respectively a combined antibiotic and/or antiphlogistic regimen (x 14 days/ monthly x 3 months) (first step) followed by L-Carnitine 1 g x 2 day + acetyl-Carnitine 0.5 g x 2/day x other 3 months (second step) and finally no drug x other 3 months (third step). 2) A2 (n = 8) and B2 (n = 16) subsets received, for a 3 month period, in the meantime the combined antibiotic and/or antiphlogistic regimen (x 14 days/monthly) and L-Carnitine 1 g x 2/day + acetyl-Carnitine 0.5 g x 2/day (first step) and finally no drug x other 3 months (second step). 3) A3 (n = 8) and B3 (n = 12) subsets received for a 3-month period L-Carnitine 1 g x 2/day + acetyl-Carnitine 0.5 g x 2 day (first step) and finally no drug x other 3 months (second step). Before and after each step of the therapeutical design, all patients underwent semen and quantitative bacteriological analyses and 60/90 semen specimens were also investigated about ROS production analysis by chemiluminescence in their 45% and 90% Percoll-generated fractions.

RESULTS

The antioxidative response either in terms of significant decrease in the ROS production and increase in some semen parameters (sperm motility and viability) were highest in the patients of A1/B1 subsets, followed by A2/B2 subsets and lowest in the A3/B3 subsets.

CONCLUSION

These results indicate that in PVE patients antimicrobials and/or antiphlogistic drugs get a full positive antimicrobial response but a partial antioxidative response, which seems to be potentiated by the addition of antioxidative agents (Carnitines). Furthermore, it is important to underline that the antioxidative treatment with Carnitines administered in the meantime with antiinfectious agents is less effective, and finally this treatment is unsuccessful without the eradication of the pro-oxidant (germs and WBC) agents.

[Mepartricin in the treatment of male pelvic pain syndrome secondary to chronic nonbacterial prostatitis/prostatodynia]

BACKGROUND

The aim of this paper is to compare the activity of mepartricin vs placebo in male pain pelvic syndrome secondary to chronic nonbacterial prostatitis/prostatodynia.

METHODS

Forty-two patients have been tested (mean age: 35 years; range 29-44), these proved affected by male pain pelvic syndrome secondary to chronic nonbacterial prostatitis/prostatodynia, and were randomized into 2 groups: the 1st treated with mepartricin 40 mg/die for 60 days, the 2nd with placebo (C vitamin 500 mg/die) for 60 days. The following patterns were examined: spontaneous and rectal examination pain, diurnal and nocturnal urinary frequency and prostatic volume. Side effects in course of therapy were examined as well.

RESULTS

Mepartricin proved significantly more active than placebo in reducing spontaneous pain, rectal examination pain, diurnal urinary frequency, nicturia and prostatic volume. No significant difference proved to emerge between placebo and mepartricin in terms of side effects.

CONCLUSIONS

These data allow us to substain that mepartricin may be a useful and safe drug for the therapy of male pain pelvic syndrome secondary to chronic nonbacterial prostatitis/prostatodynia.

Chronic urologic pain syndromes

Chronic pains typically evaluated by a urologist are discussed from the perspective of a non-urologist pain clinician. The pathophysiology of some pains is understood and so we believe the patient's symptoms: examples are cancer-related pain and recurrent urolithiasis. We treat these pains with traditional analgesics. Other pains, such as those of interstitial cystitis, chronic prostatodynia, and chronic orchialgia are less understood and so are treated in a more conservative and often empiric fashion. Proposed therapies for these disorders are discussed.

[Chronic obstructive prostatitis]

The authors review current classifications of chronic prostatitis and propose their own classification which reflects routes of prostatic infection, division of infectious prostatitis into obstructive and non-obstructive forms, etiology of chronic prostatitis. Original methods and facilities for prostatic drainage via transurethral and transrectal approaches are described.
