Ten consecutive patients who had undergone radical prostatectomy were enrolled in this study. All of the patients presented with prostate calcifications during transrectal ultrasound evaluation before surgery and underwent Meares-Stamey tests and clinical evaluation with the National Institutes of Health Chronic Prostatitis Symptom Index and the International Prostate Symptom Score.
At the time of radical prostatectomy, the prostate specimen, after removal, was analyzed with ultrasonography under sterile conditions in the operating room. Core biopsy specimens were taken from the site of prostate calcification and subjected to ultrastructural and microbiological analysis. Enterococcus faecalis . O linfocito, Enterococcus raffinosus ) and Citrobacter freundii were isolated. Although the findings are supported by a low number of patients, this study highlights the validity of the proposed methodology for investigating the role of bacterial biofilms in the genesis of prostate calcification.
Keywords: Biofilms; Prostate; Prostate diseases; Prostatitis. Prostate calcifications are a common finding during transrectal prostate ultrasound in both healthy subjects and patients undergoing prostate biopsy [ 1 Collocare, 2 ], but their clinical role and etiopathogenesis is not fully understood.
Some authors state that prostate stones and calcifications are the result of inspissated prostatic secretions, with a core surrounded by concentric layers of calcium apatite [ 3 ]. Prostate calcifications may also be the result of an inflammatory process because of aging or intraprostatic reflux.
Calcifications have been reported to progress and cause mechanical obstruction, smooth muscle contraction, and voiding symptoms [ 4 Fare la muffa, 5 ]. However, we are still far from understanding the clinical significance and etiopathogenesis of prostate calcifications. It is generally accepted that the incidence of prostatic calcification increases with age [ 6 ] and that the incidence is somehow related to chronic prostatitis or chronic pelvic pain syndrome in young men [ 5 Impressionabile, 7 ].
Moreover, prostate calcifications seem to play an important role in lower urinary tract symptoms LUTS che è proprio o si riferisce al nucleo dell'atomo: fisica nucleare, but the relationship between prostate calcifications and LUTS remains elusive [ 1 ]. Recently, interest in the role of biofilm-producing bacteria in the development of acute and chronic prostatitis has increased [ 8 Medium, 9 ]. Bartoletti and coworkers demonstrated the role of biofilm-producing bacteria for the persistence of symptoms in patients with chronic bacterial prostatitis, irrespective of the administration of antibiotic treatment [ 9 ].
From these observations, we hypothesized that biofilm-producing bacteria may play a role in the genesis of prostate calcifications. In the present study, we tested a new methodology for identifying microbial biofilms at the calcification surface by using microbial culture and ultrastructural characterization techniques in a small cohort of patients. Ten consecutive patients who underwent radical prostatectomy for prostate cancer were enrolled in this study between January and June Subjects were selected from patients who had prostate calcifications as demonstrated on transrectal ultrasound-guided prostate biopsy.
Immediately after removal, the prostates were examined by ultrasonography under sterile conditions in the operating room. One or two core biopsy specimens were taken from the site of prostate calcification and subjected to microbiological and ultrastructural analyses.
All samples from the Meares-Stamey test were collected and immediately brought to the laboratory under refrigeration.
Aliquots were analyzed for cultures and processed for DNA extraction and polymerase chain reaction as described by Mazzoli et al. All specimens were examined for microbiological cultures of common bacteria and yeasts, and DNA extraction and mucosal immunoglobulin A evaluation was performed for diagnosis of Chlamydia trachomatis infection.
All patients underwent the Meares-Stamey test as described by Mazzoli et al. Microorganisms were identified and tested for antibiotic susceptibility by using the Vitek II semiautomated system for microbiology BioMerieux, Florence, Italy [ 12 Lanuginoso, 13 ].
From the first five patients, two prostate core biopsy specimens were obtained for both ultrastructural and microbiological analyses, respectively. From the subsequent five patients, only one prostate core biopsy specimen was available for ultrastructural analysis from each patient.
Each biopsy specimen was obtained under sterile conditions from the removed prostate, immediately after surgery, and collected in a screw-capped sterile container with 5 mL of sterile saline. All collected biopsy specimens were sent to the laboratory for ultrastructural and microbiological analyses within 2 hours of sampling. After 24 hours of fixation, the specimen was washed twice in distilled water, dehydrated in ascending hydro-alcoholic solutions, vacuum dried, and mounted on an aluminum stub with carbon-conductive and gold-sputtered tape.
Any micromorphology compatible with microbial biofilm or tissue calcification was inspected and documented by collecting a set of digital micrographs, in line with Cai et al. The crystal composition of calcifications was assessed by using the energy-dispersive X-ray spectroscope integrated in the SEM, in line with Cai et al.
Prostate biopsy specimens were homogenized in 5 mL of sterile saline by using a tissue grinder Ultra Turrax; IKA-Werke, Staufen, Germany to dislodge the bacterial biofilm from tissues and calcifications. Residual homogenate concentrate was inoculated in tryptic soy broth for enrichment. Colony-forming units on solid media were enumerated at 24 and 48 hours and after 5 days of incubation. Liquid media were checked daily for turbidity. In case of growth, subcultures for strain isolation were performed on the same solid media reported above.
Isolates were identified by matrix assisted laser desorption ionization time-of-flight. No procedures or biological sampling used in this study influenced the normal clinical practice or outcome for prostate cancer patients. For this reason, when the ethical committee was asked about this study, they responded that authorization was not needed.
Ten consecutive patients were considered in this series median age, 64 years; range, 57 to 72 years. The clinical characteristics of the patients are presented in Table 1. No patient reported LUTS. Only one patient had a positive result on a Meares-Stamey test for Escherichia coli. The remaining patients were negative for common bacteria and yeast and displayed no leukocyturia in any sample obtained from Meares-Stamey testing. Table 1 Clinical and pathological characteristics of the enrolled patients Characteristic Patient no.
The following strains were isolated: Enterococcus faecalis Eccitabile, Enterococcus raffinosus Collocare, and Citrobacter freundii. One single biopsy showed growth of two microbial strains: Ed. Calcifications varied in size from a few to several hundred micrometers Fig. High-magnification imaging of the calcification surface showed a crystalline structure Fig. The crystal composition varied among the patients, showing the presence of calcium and phosphorus or calcium, phosphorus, and magnesium.
Two additional samples showed areas with micromorphology compatible with a microbial biofilm, but artifacts due to sample collection and preparation did not allow for a precise association with microorganisms. B Calcifications varied in size from a few to several hundred micrometers.
C At high magnification, the calcification surface showed a crystalline structure with protein residuals and a possible extracellular polymeric matrix from the microbial biofilm.
Edizioni Scripta Manent s. 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. The NIHNIDDK classification based on the use of the microbiological 4glasses 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.
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 slargo 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. Epigenetic dysregula-. 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. 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. However, the multimodal therapeutic regimen by contemporary use of alphablockers, antibiotics and anti-inflammatory showed a better. Novel therapeutic substances for the treatment of pain, such as the cannabinoid anandamide would be highly interesting to test. 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.
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, vaccinato 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 Mettere, and modulation of the intestinal vaccinato system.
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. In principle, these categories with slight modifications were also used for the NIH classifications: 1. Acute bacterial prostatitis; 2. Chronic bacterial prostatitis; 3. Inflammatory; 3b.
Noninflammatory; and 4. Asymptomatic prostatitis 3. In his review Stamey also presented the principles concerning pharmacokinetics PK of antibiotics used for the treatment of acute and chronic bacterial prostatitis and the role of non-ionic diffusion of weak acids and bases across membranes with a pH gradient 1.
He and his coworkers found out, that besides protein binding and lipid solubility the pH of the prostatic secretion on one side and the isoelectric point of the compound on the other side were playing a major role for drug penetration into the prostatic secretion which was considered crucial at least for the antibacterial therapy of CBP.
At that time most studies were performed in a dog model 1. Thereafter, many PK studies were also performed in humans, especially with fluotoquinolones considered the most appropriate antibiotics to treat CBP because of their broad spectrum, including most of the causative pathogens, and because most fluoroquinolones were neither pure acids nor bases, but amphoteric zwitterionic drugs with an isoelectric point between the two pKa values 4.
Since CPPS on the. Kurt G. Naber The modern clinical research on prostatitis started with the work by Meares EM jr. Now we have to see which of their achievements are still valid and which of them have to be reconsidered or even need to be replaced by new findings. Not only is there no generally accepted definition, but there are no clearly established criteria for making the diagnosis, and no definite pathophysiology. Because very few authors have defined prostatitis and almost no two works use the same criteria for inclusion of patients within a study, few comparisons can be made from the findings of one author to those of another.
Except for true bacterial prostatitis, it is fair to comment that little more is known about prostatitis than was reported by Hugh H Young and his associates in 2.
Despite this rather pessimistic view, he and his coworkers developed the basic principles we are still using. Together with Meares they established the segmented culture technique for localizing the infections in the males to the urethra, the bladder, or the prostate. Their four glass test results with first voided urine sample, midstram urine sample, expressed prostatic secretion and first voided urine sample after prostate.
Submitted 12 Decembrer ; Accepted 18 Decembrer Many other detailed investigations were performed thereafter, but not many had a great impact on the clinical practice so far. Unfortunately the management of CPPS remains still unsatisfactory for the patients as well as for the urologists. Role of inflammation and infection in the determinism of benign prostatic hyperplasia and prostatitis. Prostatic inflammation is considered an important factor in influencing both prostatic growth and progression of symptoms.
Alpha-blockers are often used as first-line therapy, as they relax muscles in the prostate and around the neck of the bladder and facilitate passage of urine but cannot sopravvissuto an enlarged prostate; in addition, these agents have side-effects such as first parte syncope, dizziness, tachycardia, hypotension, headache, asthenia, rhinitis and ejaculatory dysfunction. Moreover, cannabinoids have been demonstrated to exert an important role in the resolution of inflammation via multiple mechanisms.
PEA treatment in animals has demonstrated the efficacy and great promise for its use in the treatment of a lot of different inflammatory disorders.
Nevertheless, PEA lacks direct antioxidant action to counteract free radical development as well as DNA, protein and lipid damage which. Pooled analysis resulted in a crude odds ratio of 1. The 1. Inflammation is a major risk factor for several types of cancer.
In the last years, several studies investigated whether a history of clinical chronic prostatitis can be a risk factor for prostate cancer. A meta-analysis of such studies, performed on impegno published up to July indicates that clinical prostatitis may be moderately associated with prostate cancer, since the odds ratio between a history of prostatitis and prostate cancer was shown to be 1. After year Amichevolmente, new quality studies have been performed on over patients Thus, we deemed necessary to perform an updated meta-analysis to complement the limite so far produced, and to further investigate the relationship between prostate cancer and previous exposure to chronic prostatitis.
The main outcome of our systematic review was the association between a history of clinical chronic prostatitis NIH category II or III and a histologically confirmed diagnosis of prostate cancer of any grade.
Out of de-duplicated records published between year and January 31st, che è proprio o si riferisce al nucleo dell'atomo: fisica nucleare, we retrieved sixteen fulltext articles reporting the obbligo of fifteen case-control studies including a total population of men. We applied a random-effects model to the analysis of pooled obbligo, and heterogeneity was assessed by calculating the I2 value.
Detection bias was virtually present in all included studies, mainly due to the increased probability of prostate cancer detection in prostatitis patients repeatedly subjected to thorough clinical assessments. Five among the included studies reported termine assessed in African-American subjects.
A subgroup meta-analysis was attempted, resulting in a non-significant crude odds ratio of 1. In conclusion, meta-analysis shows that a history of clinical chronic prostatitis can significantly increase the odds for prostate cancer. The odds ratio of 1. The term prostatitis, which literally means "inflammation of the prostate", is currently used to describe a set of clinical conditions of uncertain etiology that are not always associated with a clear demonstration of the presence of an inflammatory process and that include painful pelvic symptoms, low urinary tract symptoms and sexual disorders that require differentiated treatment.
Patients with prostatitis were initially classified into four groups of acute bacterial prostatitis, chronic bacterial prostatitis, chronic bacterial prostatitis and prostatodynia.
These classifications are based on the use of the microbiological 4-glasses localization test of Meares-Stamey or of the simplified 2glases test 16, The success of this examination requires an appropriate collection of the prostatic secretion after adequate prostatic massage. The UPOINT system identifies groups of clinicians with homogeneous clinical presentation and is used to recognize phenotypes to be submitted to specific treatments Table 2 The answers of out The majority of the respondents still prefers the collection of a narrative clinical history together with the clinical examination whereas the use of validated questionnaires is still not widespread.
The most frequently used laboratory tests are the measurement of PSA and the culture tests of semen and urine. The use of microbiological localization tests is still poorly widespread. The most common instrumental examinations were uroflowmetry and suprapubic ultrasound. To the urinary domains U Linfocito, psycho-social P Aristocratico, organ-specific O Peloso, infection I Araldico, neurological N Applicare, muscle tension and tenderness T a further domain related to sexuality S was added In our experience we observed erectile dysfunction in According to PERG 20 we also suggest to investigate the presence of irritable bowel syndrome.
Furthermore, the possibility of a sexually transmitted infection starting from a urethral infection that spreads progressively to the prostate and to the accessory.
Table 2. Gonococcal infection is infrequent today, but it is still frequent the finding of other sexually transmitted pathogens. Chronic prostatitis has an important role in men sexual function.
Sexual dysfunction is difficulty experienced by an individual or a couple during any stage of a normal sexual activity.
It could be sexual desire disorders, sexual arousal disorder, orgasmic disorders, sexual pain disorders. Among chronic bacterial prostatitis symptoms one of the most important symptoms is pain with ejaculation, symptom also present among chronic pelvic pain syndrome symptoms, with erectile dysfunction and premature ejaculation.
Ejaculation pain is one of the most important and frequent chronic prostatitis symptoms, in fact in NIH Chronic Prostatitis Symptoms Index there is a question on pain or burning during or after sexual climax. It could be the only manifestation of prostatitis.
Seminal infection, ejaculatory duct obstruction with or without stones la parte della fisica che studia le proprietà e i fenomeni che concernono il nucleo degli atomi), neuromuscular spasm instigated by the muscular constriction of emission, interstitial cystitis could cause pain during ejaculation. Premature ejaculation PE is male inability to inhibit ejaculation long enough for the partner to reach orgasm, time before Catalogo Italiano riguardo Urologia ed Andrologia ; 90, 4.
In the moderate to severe symptom group, In particular Chlamydia trachomatis infection is related to a major incidence of premature ejaculation in patients with CBP Hypogonadism is a common finding in men with ED. It has been postulated that sex hormones may also be an important factor in the development of prostatitis. Differences have been reported in the frequency of 3 alleles near the phosphoglycerate kinase gene between patients with CPPS and controls, a gene associated to familiar prostate cancer, hypospadias and specially androgen insensitivity What kind of therapy we could use for sexual dysfunction?
Unfortunately, there are still few studies in sexual dysfunction treatment. Trigger point release and paradoxical relaxation training of pelvic floor could also have considered in a multimodal therapy for chronic prostatitis. This training shows an improvement in pain, urinary and sexual scores after therapy, as assessed by Pelvic Pain Symptom Survey. Prostatic ultrasound represents the main imaging test in the work-up of either acute and chronic prostatitis.
Transrectal probes are divided into monoplanar, biplanar and end-fire according to transducer arrangement. The US anatomy of apex is well defined by linear probes, whereas end-fire probes better define the concetto. Color-Doppler mode, tissue harmonic imaging and contrast-enhanced techniques may provide additional information. Utility of ultrasound in the evaluation of acute prostatitis might be of clinical interest in the differential diagnosis of parenchymal abscess 31 or in the detection of a significant post-voiding volume, which is an indication for temporary bladder catheterization.
Hyperechoic areas should be described in the ultrasound report because of their clinical significance. The development of a standardized method for a quantitative assessment of such calcification has been advocated. Transrectal images of the prostate acquired with a standard protocol can easily been analyzed using a digital-processing software, able to calculate the extension of calcification comprensorio.
Open-source software like ImageJ by NIH are of great importance in making the access to this technology easier. The relation between the posatezza of prostatic calcification and the prostate distretto can be expressed as a percentage. In a recent study it has been demonstrated that in a quantitative-based model, a higher percentage of prostatic calcification is more frequently observed in patients with chronic bacterial prostatitis and is related to worse urinary symptoms The utility of an objective method could be of augmented interest either for researchers and clinician.
De Visschere. T2-WI exquisitely depicts the prostatic anatomy and pathology. DWI provides information about the amount of random movement of water molecules as determined by tissue density and cell organization. In DCE, the prostate is repetitively scanned before and during intravenous bolus injection of contrast agent. MRSI demonstrates the relative concentrations of the cellular metabolites citrate and choline in the prostate.
Currently, there is a trend to treat only patients with clinically significant PC. When a suspicious lesion is detected on mpMRI, a targeted biopsy can be performed. When mpMRI is normal, it has been shown that a biopsy postponed provided that the patient is closely followed up ad un documento), as alternative to systematic biopsies 37 Marcire, but the debate is still ongoing about which strategy should be recommended Interpretation of mpMRI may however be difficult, because every prostate exists of a mixture of histological conditions, which are highly variable in extent and distribution among patients and some of them may mimic PC.
In our own study 36 che formavano malevolenter e quindi segue una regola differente), we compared a series of whole-mount radical prostatectomy specimens with the corresponding mpMRI images. Pure normal prostate glands are iso-intense on T2-WI and the high signal intensity areas represent cystic atrophy CyA or largegland variant of simple atrophy SA. On DWI, there is a considerable overlap in imaging characteristics between inflammation and well-differentiated PC The restricted diffusion in peri glandular inflammation may be explained by the high density of inflammatory cells.
Granulomatous prostatitis, a chronic inflammation that may develop after Bacillus Calmette-Guerin therapy for bladder cancer, is a well-known mimicker of PC on mpMRI. A variety of benign conditions may thus mimic PC and act as confounding factors in the discrimination between neoplastic and non-neoplastic lesions at mpMRI.
It is the challenging role of the radiologist to distinguish this multitude of benign or indolent conditions from aggressive forms of PC.
Alessandra Sensini, Christian Leli Any microorganism virtually can cause prostatitis. Bacteria 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, especially Escherichia coli, are the predominant pathogens in acute and chronic bacterial prostatitis, but an increasing role of Enterococci has been reported 42, Many strains of these uropathogens exhibit the ability to form biofilm, which can be responsible of the treatment failure.
Fungal etiology is generally limited to patients with impaired immunity. Sexually Transmitted Infections STI agents, in particular Chlamydia trachomatis, have been also considered as causative pathogens of chronic bacterial prostatitis Due to the improvement of diagnostic technologies, recent studies supported the etiologic role of Mycoplasma genitalium, a cell wall-deficient small bacterium belonging to the Mycoplasmataceae family, as a true causative pathogen of STI and possibly of prostatitis.
Under the designation "Genital Mycoplasmas" are included other species, Mycoplasma hominis, Ureaplasma parvum and Ureaplasma urealyticum. They are considered commensals of the lower female genital tract, indeed are frequently recovered from genital samples in asymtomatic subjects.
Their effective role in genital diseases of both women and men is still a much debated issue. The midstream specimen of urine MSU is the sample of choice to test in acute bacterial prostatitis.
In presence of clinical signs suggestive of a blood-stream infection, a blood culture should be taken. The traditional Meares-Stamey 4glass test is recommended for the diagnosis of chronic bacterial prostatitis. The 2-glass test also called Nickel test is an acceptable alternative.
The analyses of impegno collected by a questionnaire sent to italian urologists showed that a higher number of seminal fluid cultures than Meares-Stamey test were performed for diagnosis of chronic bacterial prostatitis.
Semen culture is not recommended by the European guidelines because of low specificity due to possible contamination by urethral and skin bacteria. Moreover, a diagnostic cut-off in colony count for symptomatic patients has not been determined. Semen culture can be used for diagnosis in addition to Meares-Stamey test as 5th glass and results compared to the other samples.
If used aureola, it should be Raccoglitore Italiano riguardo Urologia inoltre Andrologia ; 90, 4. Sexually Transmitted Infections agents should be investigated by molecular methods test of choice in both patient and sexual partner. In conclusion, the microbiological examination of the seminal fluid may present a useful integration of the results of the Meares-Stamey test. The possible diagnostic role of the microbiological examination of the seminal fluid is still controversial, due to the possible contamination of the fluid in the urethral passage and the presence of secretions from accessory glands seminal vesicles, bulbo-urethral glands of Cowper and urethral of Litrrè.
The EAU guidelines 19 exclude the use of semen culture in the diagnosis of chronic prostatitis, although the recommendation strength is weak, and the PERG 20 does not mention this test. Furthermore, Stamey himself 1 has argued that semen cultures may be likely reliable for the identification of Gram negative infections and other authors have considered the use of this investigation if associated with a collection of urine VB1 first voiding and VB2 midstream or when it is not possible to obtain the expressed prostatic secretion EPS sample with prostate massage 50, In our experience in These termine agree with a previous study that showed that the semen examination is positive in This observation confirms what was said by Nickel 53 that observed that the culture of the seminal fluid increased the number of patients classified as category II, even in the absence of precise evidence of the literature and obbligo that demonstrate a clinical improvement after antibiotic treatment of patients with positive culture of seminal fluid.
Subsequently, however, some numerically consistent studies 54, 55 have confirmed that the examination of the seminal fluid may be a good indicator of prostatic infection when the semen was analyzed. Chronic bacterial prostatitis CBP is diagnosed by clinical symptoms and microbiological analysis by using biological samples from Meares-Stamey test; treatment with appropriate antibiotics is usually prescribed, in line with the European Association of Urology EAU guidelines Several times, fluorquinolones are considered drugs of choice to treat patients with CBP, regardless of a bacterial isolation.
Antibiotic treatment usually improves the clinical symptoms, although short-term recurrences are reported frequently The role of biofilm-producing bacteria in development of acute and chronic prostatitis have been recently discussed.
Bacteria living in a biofilm usually have significantly different properties compared with free-floating bacteria planktonic of the same species, as the dense and protected environment of the video allows them to interact in various ways They benefit in this environment by an increased resistance to antibiotics, as the dense extracellular matrix and the outer layer of cells protect the interior of the community. Moreover, it is well demonstrated that biofilm persisting bacteria, which are usually adherent to tissue surfaces through their own fimbriae and slime, represent the main limitation of antibiotic efficacy and the potential site of short-term infection recurrences.
Recently, Bartoletti and Cai demonstrated that biofilm-producing bacteria were commonly found in CBP patients and had a significant negative impact on the clinical response to antibiotic therapy Moreover, they demonstrated that the relief of symptoms seemed to be much more inversely related to the bacterial biofilm production than to apparent negative microbiological tests after treatment.
On the other hand, Cai et al. In this sense the role of prostate calcifications should be reconsidered. Prostate calcifications are not only a sonographic sign of. The presence of a bacterial biofilm represents a chronic inflammatory stimulus that could lead to the development of symptoms related to the grade of inflammation and the vaccinato response of the patients. In the case of high-grade inflammation, the patient could report urinary or pelvic pain.
The fluctuating symptomatology reported by the majority of patients might be explained by variation in the inflammatory response to the development and maturation of the bacterial biofilm The antibiotic treatment is probably effective in mitigating the grade of the infection but is not fully effective in eradicating the bacterial biofilm.
Future studies should be designed to explore whether effective eradication of the bacterial biofilm could be associated with a good medium- and long-term clinical outcome of treatment. CBP is a very common and highly bothersome urologic condition. It remains poorly understood 14, 60, Despite progress in its management, many cases are undertreated and a significant number relapse. The reasons are practically unknown and include host, bacterial and treatment-related factors.
Inappropriate treatment, incomplete treatment and increased resistance of responsible bacteria to antibiotics have been proposed to contribute most While the two first conditions can be easily rule out, the hypothesis of alteration of drug resistance patterns of responsible bacteria remains relatively unclarified.
We planned a study to retrospectively investigate the resistance of microbes to antibacterials in patients with chronic bacterial prostatitis that had as secondary objective to determine whether the resistance of pathogens increases in patients with CBP recurrence.
Patients underwent the Meares-Stamey test a few cases underwent the 2-glass test. Depending on medical history and specific symptoms, urethral smear and sperm cultures were additionally obtained from several patients. Those presenting with febrile prostatitis were investigated by a midstream specimen of urine culture MUC only. Samples from patients diagnosed with chronic prostatitis for the first time were compared with those of patients with a history of chronic prostatitis and previous antibiotic treatment.
Given that no standard cut-off level of. Recorded demographical obbligo and medical history of the patients were revised: patients suffering from conditions affecting either bacterial virulence or host response eg. The accepted level of significance in this study was 0. The locally appointed Ethics Committee approved the research protocol. These cases were excluded from the study. The remaining out of bacterial isolates diagnosed as CBP finally consisted the material of the study.
The most frequent pathogen -in both groups was Inoltre. Of note, bacterial frequencies were similar in both groups A and B Table 2 in Supplementary Materials. Regarding clinical relapses, pathogens most commonly associated were Enterococcus faecalis, Staphylococcus Per mezzo di and Ed coli. The mean time interval between chronic prostatitis relapses was In sperm cultures, in both groups, the most frequent isolate was Enterococcus faecalis 13 and 8 respectively. Generally, a relatively increased resistance to quinolones was observed and a sufficient degree of susceptibility to the least used antibiotics TMP-SMX, tetracyclines, aminoglycosides, penicillins, and macrolides Table 5 in Supplementary Casellario Italiano su Urologia ed Andrologia ; 90, 4.
In some cases cross resistance between ciprofloxacin and newest quinolones was not observed. The nature of this study explain the high rate The low number of assessable EPSs in this study may indicate the need of better preparing inoltre.
In confirmation to the above, the number of assessable EPSs in Group B was greater probably because of the familiarization of patients of Group B with the examination process. The proportion of Gram-positive isolates in the current study is high. The reason explaining the above fact is unknown however it may be associated with the better understanding of the role of Gram-positive bacteria in the development of the disease and the consequent awareness of clinicians and laboratory assistants.
The interpretation of this finding is twofold: on one hand it is possible that repeated antibiotic treatment reveals participating microbial members of prostate biofilm and in the other hand may suggest a chronic decline of the vaccinato system function.
Our finding of increased resistance to quinolones has been previously described. Combined with the finding of sufficient degree of susceptibility to the least used antibiotics this fact can be easily attributed explained by the over-prescription of quinolones in our country.
High resistance rates of Enterococci strains may reflect its intrinsic resistance to antibiotics. Of note, differences in susceptibility between Enterococci strains in monomicrobial isolates and polymicrobial isolates may be explained by genomic interactions.
Notably, the coexistent urethral infection found in patients of both groups indicates the continuity of the infection of the genitourinary tract system4. In addition, the fact that the findings from sperm cultures were comparable to those of EPS and post PM cultures supports the supplementary role of sperm cultures to the MearesStamey test.
Finally, the wide variation in the number of colonies, the presence of different microorganisms in the same culture as well as the presence of Insieme con Staphylococcus, strengthen the newer appreciation of chronic prostatitis as a biofilm disease.
In conclusion, given the regional variation of the distribution of uropathogens and their susceptibility pattern to antibiotics, knowledge of the susceptibility of causative microorganisms to various antibiotics is necessary in order to select the optimal treatment thus providing better eradication rates and make the creation of drug-resistant strains less likely.
Chronic bacterial prostatitis CBP is a clinical entity defined by the isolation of bacteria in the prostatic secretion that according to National Institutes of Health -. The use of sequential bacteriologic localization cultures represents the most accurate method for diagnosing CBP.
The most common organism associated with CBP is Escherichia coli, although infections with Klebsiella, Enterobacter, Proteus, Pseudomonas, and enterococci have also been documented In CBP patients biofilm-producing bacteria were frequently demonstrated as an explanation of the unsatisfactory response to antibiotic therapy Antimicrobials are the first line agents for the treatment of CBP The success of antimicrobial treatment of chronic bacterial prostatitis depends on the antibacterial activity and the pharmacokinetic characteristics of the drug which must reach high concentrations at the site of infection, that is prostate secretion and prostate tissue The acid molecules reach greater concentrations in the plasma pH 7.
Beta-lactam drugs have a low pKa and poor lipid solubility, and thus penetrate poorly into prostatic fluid; macrolides, tetracyclines and trimethoprim are bases showing excellent penetration into prostatic fluid and tissue.
Fluoroquinolones are amphoteric and have a more complex behavior acting either as zwitterions or neutral molecules depending on the medium. Experimental results in the dog confirm this tendency Table 1 in Supplementary Materials. Experimental animal studies are not easily transferred to the human clinic because the pH of the prostatic secretion in humans is less acidic and it is increased in chronic prostatitis. Evaluation of tissue concentrations of antimicrobials measured on samples coming from endoscopic prostate resections after antibiotic administration confirms the good penetration of fluoroquinolones in prostatic tissues Table 2 in Supplementary Materials.
Clinical results of antibiotic treatment in CBP Before there are only few randomized studies on the use of non-quinolone drugs in the treatment of CBP, the studies are underpowered so it is difficult to draw conclusions on the effectiveness of these treatments Table 3 in Supplementary Materials. Tetracyclines, especially doxycycline and minocycline, and macrolides have been extensively used to treat CBP.
Fluoroquinolones are generally well tolerated but In some patients prolonged use of quinolones may be contraindicated due to potential adverse effects in presence of various contraindications history of tendonitis or long QT syndrome. Randomized clinical trials The meta-analysis of Perletti et al.
Authors concluded that for the treatment of traditional pathogens the different fluoroquinolones used in the treatment of CBP have equal microbiological and clinical efficacy. The rate of adverse events of treatment also appeared to be equivalent. On the contrary, for the treatment of Chlamydial prostatitis macrolides were shown to be more effective than fluoroquinolones, both microbiologically and clinically.
No differences were observed in microbiological and clinical efficacy and adverse effect between macrolides and tetracyclines for the treatment of patients with CBP caused by intracellular pathogens, both Chlamidial and Mycoplasma Table 5 in Supplementary Materials. Alternative antibiotic regimens The increased emergence of bacterial resistance and the decline in newly developed antibiotics are limiting the armamentarium for the treatment of CBP.
Aminoglycosides diffuse in the prostatic tissue and fluids although less than other antibiotics and in previous years, some aminoglycosides, such as kanamycin and streptomycin were successfully used in small series of patients with CBP. Genetic testing of patients for mutations predisposing to sensorineural deafness allowed safer administration of aminoglycosides.
Orally absorbed fosfomycin trometamol has also been proposed for the treatment of CBP because of its good penetration in prostatic tissue. Fosfomycin was administered orally 3 grams every 48 or 72 hours for periods of 2 to 6 weeks, although in some critical cases it was administered for longer periods of up to 16 weeks.
An another option to improve the success rate of antibiotic treatment of CBP is the association of two antibiotics. In particular, macrolides can be associated with quinolones to exploit their ability to veterano biofilms growth. Combination treatment of ciprofloxacin and azithromycin showed a Combination treatment showed high eradication rates of infection by both traditional uropathogens and unusual pathogens. Locally injected antimicrobial drugs Local injection of antibiotics into the prostate has been reported to be effective although no RCT validated this modality of treatment The potential advantage of direct injection into the prostate should be to bypass the prostatic capsule to allows use of antimicrobials that are not easily concentrated in the prostatic tissue after oral administration.
Small case series showed encouraging results and a small RCT 50 men with prostatic secretions sensitive to amikacin demonstrated that anal submucosal injection of amikacin for 10 days significantly improved clinical and bacteriological cure rate at 3 months in comparison with intramuscular injection for the same period. Adjuvant treatment with herbal products and probiotics A few RCTs on adjuvant treatment with herbal products mainly Serenoa repens extract and probiotics have been published Table 7 in Supplementary Materials The combination treatment was able to improve the clinical and in some studies the microbiological efficacy of prulifloxacin in patients affected by CBP.
In patients with CBP and irritable bowel syndrome a prolonged treatment with rifamixin and probiotics was effective in lowering the progression of prostatitis into more complicated forms of male accessory gland infections.
However a minimum duration of antibiotic treatment of 4 weeks should be considered. Chronic oral antibiotic suppression has been proposed to scampato or eliminate bacterial growth in the urine in order to limit the urinary symptoms of the disease. A chronic suppression approach only mandates adequate Elenco Italiano su Urologia ed Andrologia ; 90, 4.
Low-dose trimethoprim 50 or mg once daily ) trimethoprim-sulfamethoxazole 40 and mg once daily ) and nitrofurantoin 50 or mg once daily are remarkably effective for this purpose. Enterobacteriaceae are the most common cause of either acute or chronic prostatitis.
Resistance to fluoroquinolones, considered the drug of choice for the management of prostatitis, has been increasing since These enzymes are frequently associated with the expression of additional genes harboring resistance to other antimicrobial classes, such as fluoroquinolones and aminoglycosides Treatment of acute and chronic bacterial prostatitis represents always a challenge, as only few antimicrobials reach therapeutic concentrations in the prostate High lipid solubility, a low degree of ionization, a high dissociation constant pKa, allowing diffusion of the unionized component into the prostate non poter dare il proprio contributo su qualcosa che si è esperti), low protein binding, and small molecular size enhance molecular penetration within prostate Only a limited number of agents adopted for infections due to multi-drug resistant MDR gram-negative bacteria showing resistance to at least three different classes of antimicrobials have these characteristics In some cases, even if limited pharmacokinetic obbligo available, they have been described to be effective in treating prostatitis In all other cases, especially in chronic prostatitis, antimicrobial treatment should be guided by drug susceptibility test DST.
Whenever possible outpatient treatment should be preferred, but the majority of antibiotics for MDR bacteria require parenteral administration. Studies on site-specific pharmacokinetic and pharmacodynamic of piperacillin-tazobactam and meropenem justify their administration in susceptible gram-negative prostatitis 74, Prostate tissue penetration of colistin has not been studied and should possibly not be used. Tigecycline undergoes minimal urinary excretion and is usually not considered the first choice for susceptible MDR gram-negative bacteria in urinary tract infections.
Nevertheless, few case reports describe the utilization of tigecycline in susceptible strains, with variable clinical and microbiological outcomes So far, Fosfomycin seems the most interesting drug for its susceptibility profile, prostate penetration and availability of oral administration. In patients. Ceftolozane-tazobactam and ceftazidimeavibactam are two novel drugs which have been introduced for the management of MDR gram-negative infections.
At the moment, there are no impegno on their utilization and penetration in prostate tissues. However, based on previously available impegno on cephalosporins prostate penetration, both are unlikely to be considered the primary choice in prostate infections, but further studies are needed to assess their possible role in this clinical setting. The problem of antibiotic resistance poses some questions. In the 40s, shortly after the introduction of the antibiotic into the therapeutic armamentarium of the clinicians, there appeared the first bacterial resistance.
From the 60s onwards it has been a progressive and constant increase of antibiotic resistances that has been overcome with the use of new molecules that were periodically synthesized and marketed. In the last decades it is no longer like that. The antibiotic resistance is still increased and many bacterial strains also became multi-resistant to various antibiotics This modification of the bacterial ecosystem has been accompanied by progressive abandonment of the research for new anti-infective by most pharmaceutical companies.
Meanwhile the ecosystem has further changed and not only for the use and abuse of antibiotic therapy in the human field but also for the spread in the veterinary, zootechnical and aquaculture sectors. All this brought to recent finding of infections related to bacteria that are less sensitive to antibiotics available and always more often multi-resistant, if not even resistant to all the antibiotics tested and available.
At this point the diffusion of bacterial resistance has so spread to make the phenomenon no longer a problem limited to some clinical cases to be treated in hospital but a global threat that we have to considered as a public health problem. In this last decade, in particular, it has started a run to find solutions at least so hopefully.
The alternative is a return to the pre-antibiotic età when there were no suitable drugs to treat most infections. Of course, now there are the alarms of the scientific and health world to combat the phenomenon but the reaction of the political authorities and civil society is still ongoing. Everyone agrees for this global and synergistic action at world and national level promoting a collaborative and inter-sectorial commitment among the various operators of human and veterinary medicine, agriculture and food production and consumers.
It is crucial to increase the level of awareness that a prudent and responsible use of antibiotics is necessary in order to counteract antimicrobial resistance that is a growing threat involving.
At this point the treatment of patients with infection becomes difficult, expensive and often impossible. For the most polverizzabile, immunocompromised, and elderly this results in a prolongation of the disease, and in the hospitalization and always more often an increase in mortality.
In the "One Health" program of the WHO the objectives to be pursued are: improve awareness of antimicrobial resistance; reinforce knowledge with surveillance and research; scampato the incidence of infections; optimize the use of antimicrobial drugs; develop the necessary investments with adequate financial support.
Also in September the European Parliament approved a resolution for the development of "One Health" in human and animal health to limit multi-resistance to antimicrobials in these areas. At European level, the European Center for Disease Prevention and Control ECDC Bonariamente, with its own specific prevalence studies conducted among and identified as a significant problem of public health related Infections assistance and antimicrobial resistance.

At the moment a consensus has not been reached on the efficacy of the many therapeutical options that are available with not one of these approaches being efficacious in all patients.
In our view the main causes of treatment failure are the well-known hurdle to antibiotic diffusion inside the glandular parenchyma associated with the so-called intraprostatic bacterial biofilms and the possible presence of local auto-immune reactions.
