Semen analysis in chronic bacterial prostatitis: diagnostic and therapeutic implications
The significance and diagnostic value of semen analysis in chronic bacterial prostatitis has been extensively debated
and remains controversial. To investigate the diagnostic relevance of semen culture in the bacteriological workup of prostatitis patients, we retrospectively analyzed a clinical database of 696 symptomatic patients. All patients were routinely subjected to a four-glass test, followed by semen culture and analysis. This allowed to dissect from the database three different diagnostic scenarios, and to compare the \u2018two-glass\u2019 pre-/post- massage test and the standard
\u2018four-glass\u2019 test with a \u2018five-glass\u2019 test (four-glass plus post-VB3 semen culture). The \u2018five-glass\u2019 test showed 3.6- or 6.5-fold increases in relative sensitivity and lesser reductions (\u201313.2% or \u201314.7%) in relative specificity for traditional
uropathogens (TUs) compared with the four-glass or two-glass test, respectively. The area under the ROC curve and Jouden\u2019s index were increased, whereas positive and negative likelihood ratios were lower than comparators, indicating that the \u2018five-glass\u2019 assay may be superior in confirming the negative outcome of both standard tests. The five-, four-, and two-glass tests detected TUs (Enterobacteriaceae, Enterococci, etc.) in 120, 33, and 20 patients and unusual pathogens (Streptococci, other Gram-positive species, Mycoplasmata, and others) in 130, 56, and 45 patients, respectively. When patients were subjected to pharmacological treatment, including a combination of a fluoroquinolone and a macrolide, no
differences in eradication rates were observed between groups diagnosed with different tests, irrespective of pathogen category. Eradication was associated with long-term sign/symptom remission; no significant intergroup differences in sign/symptom scores were observed throughout a 24-month off-therapy follow-up period. In conclusion, our data support the usefulness of semen analysis in the diagnostic workup of prostatitis patients when this test is used to complement thefour-glass Meares and Stamey test. Improvement of microbiological assays conveys important diagnostic and therapeutic
implications
Ukrainian Version of the Acute Cystitis Symptom Score (ACSS) for Diagnostics and Patient-Reported Outcome of Acute Uncomplicated Cystitis. Part I. Linguistic validation and Cognitive assessment
The Acute Cystitis Symptom Score (ACSS) was originally
developed in Uzbek and Russian language as a self-reporting
questionnaire for the clinical diagnosis and follow-up of an acute episode of uncomplicated cystitis (AC) in women based on complains and their effect on the quality of life. After professional forward and backward translations the cognitive assessment of the Ukrainian version of the ACSS was performed in female subjects with different ages and educational levels and in medical professionals treating such patients. After considering all comments of the female subjects and the professionals the final version of the Ukrainian ACSS could be obtained to be further used in
clinical studies
Solutions of a particle with fractional -potential in a fractional dimensional space
A Fourier transformation in a fractional dimensional space of order \la
(0<\la\leq 1) is defined to solve the Schr\"odinger equation with Riesz
fractional derivatives of order \a. This new method is applied for a particle
in a fractional -potential well defined by V(x) =-
\gamma\delta^{\la}(x), where and \delta^{\la}(x) is the
fractional Dirac delta function. A complete solutions for the energy values and
the wave functions are obtained in terms of the Fox H-functions. It is
demonstrated that the eigen solutions are exist if 0< \la<\a. The results for
\la= 1 and \a=2 are in exact agreement with those presented in the standard
quantum mechanics
Multidisciplinary approach to prostatitis
The modern clinical research on prostatitis started with the work of Stamey and coworkers who developed the basic principles we are still using. They established the segmented culture technique for localizing the infections in the males to the urethra, the bladder, or the prostate and to differentiate the main categories of prostatitis. Such categories with slight modifications are still used according to the NIH classification: acute bacterial prostatitis, chronic bacterial prostatitis, Chronic Pelvic Pain Syndrome (CPPS) and asymptomatic prostatitis. Prostatic inflammation is considered an important factor in influencing both prostatic growth and progression of symptoms of benign prostatic hyperplasia and prostatitis. Chronic inflammation/neuroinflammation is a result of a deregulated acute phase response of the innate immune system affecting surrounding neural tissue at molecular, structural and functional levels. Clinical observations suggest that chronic inflammation correlates with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and benign prostatic hyperplasia (BPH) and an history of clinical chronic prostatitis significantly increases the odds for prostate cancer. The NIHNIDDK classification based on the use of the microbiological 4- glasses localization test or simplified 2-glasses test, is currently accepted worldwide. The UPOINT system identifies groups of clinicians with homogeneous clinical presentation and is used to recognize phenotypes to be submitted to specific treatments. The UPOINTS algorithm implemented the original UPOINT adding to the urinary domains (U), psycho-social (P), organspecific (O), infection (I), neurological (N), muscle tension and tenderness (T) a further domain related to sexuality (S). In fact sexual dysfunction (erectile, ejaculatory, libido loss) has been described in 46-92% of cases with a high impact on the quality of life of patients with CP/CPPS. Prostatic ultrasound represents the most popular imaging test in the work-up of either acute and chronic prostatitis although no specific hypo-hyperechoic pattern has been clearly associated with chronic bacterial prostatitis and CPPS. Use of a digital-processing software to calculate the extension of prostatic calcification area at ultrasound demonstrated a higher percentage of prostatic calcification in patients with chronic bacterial prostatitis. Multiparametric Magnetic Resonance Imaging (mpMRI) is the current state-of-the art imaging modality in the assessment of patients with prostate cancer although a variety of benign conditions, including inflammation, may mimic prostate cancer and act as confounding factors in the discrimination between neoplastic and non-neoplastic lesions. Bacteria can infect prostate gland by: ascending the urethra, reflux of urine into the prostatic ducts, direct inoculation of bacteria through inserted biopsy needles or hematogenous seeding. Enterobacteriaceae are the predominant pathogens in acute and chronic bacterial prostatitis, but an increasing role of Enterococci has been reported. Many strains of these uropathogens exhibit the ability to form biofilm and multidrug- resistance. Sexually Transmitted Infections (STI) agents, in particular Chlamydia trachomatis and Mycoplasma genitalium, have been also considered as causative pathogens of chronic bacterial prostatitis. On the contrary the effective role in genital diseases of other "genital mycoplasmas" is still a much debated issue. Sexually Transmitted Infections agents should be investigated by molecular methods in both patient and sexual partner. "Next generation" investigations, such as cytokine analysis, cytological typing of immune cells could help stratifying the immune response. Epigenetic dysregulation of inflammatory factors should be investigated according to systemic and compartment-specific signals. The search for biomarkers should also include evaluation of hormonal pathways, as measurement of estrogen levels in semen. Antimicrobials are the first line agents for the treatment of bacterial prostatitis. The success of antimicrobial treatment depends on the antibacterial activity and the pharmacokinetic characteristics of the drug which must reach high concentrations in prostate secretion and prostate tissue. Acute bacterial prostatitis can be a serious infection with a potential risk for urosepsis For iInitial treatment of severely ill patients, intravenous administration of high doses of bactericidal antimicrobials, such as broad-spectrum penicillins, third-generation cephalosporins or fluoroquinolones, is recommended in combination with an aminoglycoside. Use of piperacillin-tazobactam and meropenem is justified in presence of multiresistant gramnegative pathogens. The antibiotic treatment of chronic prostatitis is currently based on the use of fluoroquinolones that, given for 2 to 4 weeks, cured about 70% of men with chronic bacterial prostatitis. For the treatment of Chlamydial prostatitis macrolides were shown to be more effective than fluoroquinolones, whereas no differences were observed in microbiological and clinical efficacy between macrolides and tetracyclines for the treatment of infections caused by intracellular pathogens. Aminoglycosides and fosfomycin could be considered as a therapeutic alternative for the treatment of quinolone resistant prostatitis. Use of alpha-blockers in CP/CPPS patients with urinary symptoms and analgesics +/- non steroidal anti-inflammatory drugs (NSAID), in presence of pain demonstrated a reduction of symptoms reduction and an improvement of quality of life, although long term use of NSAID is limited by side effect profile. However, the multimodal therapeutic regimen by contemporary use of alphablockers, antibiotics and anti-inflammatory showed a better control of prostatitis symptoms than single drug treatment. Novel therapeutic substances for the treatment of pain, such as the cannabinoid anandamide would be highly interesting to test. An alternative for the treatment of chronic prostatitis/chronic pelvic pain syndrome is phytotherapy, as primary therapy or in association with other drugs. Quercetin, pollen extract, extract of Serenoa repens and other mixtures of herbal extracts showed a positive effect on symptoms and quality of life without side effects. The association of CP/CPPS with alterations of intestinal function has been described. Diet has its effects on inflammation by regulation of the composition of intestinal flora and direct action on the intestinal cells (sterile inflammation). Intestinal bacteria (microbiota) interacts with food influencing the metabolic, immune and inflammatory response of the organism. The intestinal microbiota has protective function against pathogenic bacteria, metabolic function by synthesis of vitamins, decomposition of bile acids and production of trophic factors (butyrate), and modulation of the intestinal immune system. The alteration of the microbiota is called "dysbiosis" causing invasive intestinal diseases pathologies (leaky gut syndrome and food intolerances, irritable bowel syndrome or chronic inflammatory bowel diseases) and correlating with numerous systemic diseases including acute and chronic prostatitis. Administration of live probiotics bacteria can be used to regulate the balance if intestinal flora. Sessions of hydrocolontherapy can represent an integration to this therapeutic approach. Finally, microbiological examination of sexual partners can offer supplementary information for treatment
AKUTE UND CHRONISCHE PROSTATITIS - WAS IST WICHTIG FÜR DIE PRAXIS?
Die Prostatitis ist eine häufige und komplexe Erkrankung. Im Verlauf der letzten 40 Jahre haben sich verschiedene Stadien der wissenschaftlichen Wahrnehmung, zum Teil mit Erfolgen und zum Teil mit Irrwegen aufgezeigt. Während die akute Prostatitis fast immer einer akuten bakteriellen Infektion entspricht, finden sich beim chronischen Prostatitissyndrom nur in etwa 10 % der Fälle ursächliche Erreger. Das Erregerspektrum entspricht im Wesentlichen dem von komplizierten Harnwegsinfektionen mit vornehmlich Gram-negativen Erregern. In manchen Studien wurden aber auch atypische Erreger, wie Chlamydia trachomatis und Mykoplasmen gefunden. Bei der überwiegenden Mehrzahl der Fälle werden multifaktorielle Ursachen angenommen. Dies führte schließlich zur Phänotypisierung der Beschwerdesymptomatik mit multimodalen Therapiekonzepten. Bei eindeutig infektiöser (Mit-)Ursache der Beschwerden haben Antibiotika – allen voran Fluorchinolone – nach wie vor einen hohen Stellenwert. Ansonsten erfolgen multimodale Therapiestrategien, die auf Evidenz-basierten monotherapeutischen Studien aufbauen. Bisher liegen nur wenige Studien zu multimodalen Kombinationstherapien vor, die aber durchaus vielversprechend sind
