RESUMEN

PURPOSE: Because of the insufficient efficacy of the current treatment of chronic bacterial prostatitis (CBP), it is justified to search for a more effective antibiotic therapy (ABT). MATERIALS AND METHODS: This single-centre prospective observational comparative study was conducted in 2012 to 2019 (patients: 60 men with CBP; age: 20-45 y). The clinical examination was performed on admission and at 1, 3, 6, or 12 months. All patients underwent the Meares-Stamey test to obtain expressed prostatic secretion (EPS) and/or post-massage urine (PMU) samples for extended bacteriological examination. The patients were randomly divided into 2 treatment groups (30/30 patients): group I, fluoroquinolones (FQs); group II, a combination of FQs with cephalosporins/macrolides with a treatment duration of 1 month. RESULTS: Patients of both groups had severe symptomatic CBP with an average duration of 4 years. Twenty-three microorganisms (15 aerobes, 9 anaerobes) were identified in PMU. At 3 months follow-up, a positive clinical effect was noted in both groups, which was significant (p<0.05) only in group II concerning NIH-CPSI questionnaire, leukocyturia, prostate volume, maximum urine flow, and decreased pathospermia. At 6 months follow-up, in group II the frequency of Escherichia coli and Enterococcus spp. decreased significantly. In group I aerobes changed only insignificantly from the initial level, but anaerobes increased significantly. In group II the titers of both, aerobes and anaerobes, were significantly lower (p<0.05) at 6 months follow-up as compared to initial values. CONCLUSIONS: ABT targeting all taxa in EPS/PMU is a more effective alternative to standard therapeutic regimens for CBP.

RESUMEN

Finasteride is an antiandrogenic drug used for the clinical treatment of chronic nonbacterial prostatitis (CNP). Recently, we reported the anti-CNP activity of Poria cocos polysaccharides (PPs) in a rat model. In this study, we compared the differences between PPs and finasteride in treating CNP, especially their effects on the gut microbiota. Results showed that both PPs and finasteride significantly reduced the prostate weight and prostate index of CNP rats, and improved the histological damages in the inflamed prostate. Moreover, PPs and finasteride inhibited the production of pro-inflammatory cytokines (TNF-α, IL-2 and IL-8) and androgens (dihydrotestosterone and testosterone). By 16S rDNA sequencing, PPs and finasteride were found to reprogram the gut microbiota into distinct profiles. Further analysis presented that PPs but not finasteride recovered CNP-induced changes in the gut microbiota, including Ruminococcaceae NK4A214 group, uncultured bacterium f Ruminococcaceae, Ruminiclostridium 9, Phascolarctobacterium, Coriobacteriaceae UCG-002 and Oribacterium. LDA effect size (LEfSe) analysis revealed that PPs recovered the gut microbiota by targeting Ruminococcaceae NK4A214 group. Our results suggested that PPs alleviated CNP via different mechanisms from finasteride, especially by regulating the gut microbiota, which offers therapeutic target for the treatment of CNP.

RESUMEN

Chronic nonbacterial prostatitis (CNP) is a common male disease with high incidence and low cure rate. This study aims to investigate the anti-CNP potential of Poria cocos polysaccharides (PPs) in a λ-carrageenan-induced CNP rat model. Results showed that PPs exerted anti-CNP functions by reducing the prostate weight and prostate index as well as the level of C-reactive protein (CRP) and pro-inflammatory cytokines (TNF-α and IL-1ß). Further analysis on sex hormones revealed that PPs could favor CNP alleviation by regulating the production of testosterone (T), dihydrotestosterone (DTH), and estradiol (E2). PPs could also alleviate CNP by regulating the level of inducible nitric oxide synthase (iNOS), malonaldehyde (MDA), and superoxide diamutase (SOD) in inflamed prostate, thereby enhancing the anti-oxidative stress activity. As most non-digestive polysaccharides are fermented by gut microbiota rather than being digested directly by the host, we further analyzed PP-induced changes in gut microbiota. Microbiomic analysis revealed that PPs significantly change the profile of gut microbiota. Moreover, the relative abundance of five genera was recovered by PPs with a dose-effect relationship, thereby being suggested to play critical roles in the alleviation of CNP. Epigenomic (methylomic) analysis showed that PPs remodeled the DNA methylome of intestinal epithelia, by which PPs might modify hormone production. In the present study, we reported the anti-CNP activity of PPs as well as the involved mechanisms.

RESUMEN

This paper presents the results of a pilot study of difficult-to-treat patients (exhibiting several previous treatment failures or detection of extended-spectrum beta-lactamase [ESBL] strains) with chronic bacterial prostatitis (CBP) who underwent treatment with fosfomycin trometamol (FT) and N-acetyl-L-cysteine (NAC). Twenty-eight patients with clinically- and microbiologically-confirmed CBP who attended a single urological institution between January 2018 and March 2019 were treated with oral administration of 3 g FT once a day for 2 days, followed by a dose of 3 g every 48 h for 2 weeks, in combination with oral administration of NAC 600 mg once a day for 2 weeks. Clinical and microbiological analyses were carried out at the time of admission (T0) and during follow-up at 1 month (T1) and 6 months (T2) after the end of treatment. Symptoms were assessed by the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) and International Prostatic Symptom Score (IPSS), and quality of life was assessed by Quality of Well-Being (QoL) questionnaires. Isolated strains were Escherichia coli (23 patients), Enterococcus spp. (3 patients), and Klebsiella oxytoca (2 patients). ESBL strain was found in 19 (67.8%) patients. Microbiological eradication was documented in 21 (75%) patients at the second follow-up visit and clinical cure was achieved in 20 (71.4%) patients. Significant changes on questionnaires were recorded between baseline and follow-up visits. Fifteen of 19 patients (78.9%) with ESBL strains were cured. No significant side effects were reported. FT in combination with NAC is a promising alternative therapy in difficult-to-treat CBP patients.

RESUMEN

Flomoxef is used to treat bacterial prostatitis; however, its prostatic pharmacokinetics have not been fully clarified. Flomoxef (500 or 1000 mg) was administered to patients with benign prostatic hypertrophy (n = 54). After a 0.5-h infusion, venous blood samples were drawn at time points of 0.5-5 h, and prostate tissue samples were collected at time points of 0.5-1.5 h during transurethral resection of the prostate. The drug concentrations in plasma and prostate tissue were analyzed pharmacokinetically and used for a stochastic simulation to predict the probability of attaining pharmacodynamic target in prostate tissue. Showing dose linearity in the prostatic pharmacokinetics, flomoxef rapidly penetrated into prostate tissue, with a prostate/plasma ratio of 0.48-0.50 (maximum drug concentration) and 0.42-0.55 (area under the drug concentration-time curve). Against the tested populations of Escherichia coli, Klebsiella and Proteus species isolates, 0.5-h infusion of 1000 mg three times daily achieved a ≥90% expected probability of attaining the bactericidal target (70% of the time above the minimum inhibitory concentration [MIC]) in prostate tissue. The site-specific pharmacodynamic-based breakpoint (the highest MIC at which the target-attainment probability in prostate tissue was >90%) values were 0.25 mg/L (MIC for 90th percentile of E. coli and Klebsiella species) for 500 mg four times daily and 0.5 mg/L (MIC90 of Proteus species) for 1000 mg four times daily. These results help to fully characterize the prostatic pharmacokinetics of flomoxef, while also helping to rationalize and optimize the dosing regimens for prostatitis based on site-specific pharmacodynamic target attainment.

RESUMEN

INTRODUCTION: To evaluate the efficacy of Bifiprost® + Serenoa Repens 320 mg versus Serenoa Repens 320 mg alone for the prevention of chronic bacterial prostatitis (CBP) due to enterobacteriaceae. METHODS: Between September 2016 and September 2018, 120 patients with CBP at the National Institutes of Health (NIH type II) with recurrent infections due to enterobacteriaceae (Escherichia Coli and Enterococcus faecalis) were enrolled and randomized into 2 groups each to receive Bifiprost® + Serenoa Repens 320 mg (Group A) or Serenoa Repens 320 mg alone (Group B) daily for 24 weeks (after receiving a proper antibiotic treatment with subsequent culture negativization). The primary endpoint was the reduction in the episodes of prostatitis. The secondary endpoint evaluated was the score of the NIH-Chronic Prostatitis Symptom Index (NIH-CPSI). Evaluation was performed at baseline and at 12, 24, and 36 weeks. RESULTS: The patients of the Group A experienced a significantly larger reduction in the prostatitis episodes than the Group B at 24 and 36 weeks, but they did not experience a significantly larger reduction at 12 weeks. After 12 weeks of treatment, the mean NIH-CPSI score was reduced in both groups compared with baselines, but no significant differences were seen between the Group A and Group B. On the contrary, we observed a significant difference in the mean NIH-CPSI score between the 2 groups at 24 and 36 weeks. CONCLUSION: The association of Bifiprost® and Serenoa Repens 320 mg improves the prevention of the episodes of CBP due to enterobacteriaceae and ameliorates prostatitis-related symptoms after 6 months of therapy. The long-term impact on the entero-urinary route was also seen 3 months after the end of the treatment.

RESUMEN

BACKGROUND: Chronic bacterial prostatitis (CBP) is a difficult-to-treat infection as only a few antibiotics achieve therapeutic concentrations in the prostate. Data on the efficacy and safety of oral fosfomycin for the treatment of CBP are limited. OBJECTIVES: To analyse the efficacy and safety of fosfomycin in CBP due to MDR pathogens. METHODS: In a prospective observational study, an oral regimen of 3 g of fosfomycin q24h for 1 week followed by 3 g q48h for a treatment duration of 6-12 weeks was administered. The outcome was clinical and microbiological cure rate at the end of treatment (EOT) and rate of relapse at 3 and 6 months. RESULTS: The study included 44 patients. The most common pathogen was Escherichia coli (66%), followed by Klebsiella spp. (14%) and Enterococcus faecalis (14%). Most strains were MDR (59%) and 23% had an ESBL phenotype; 33 of 44 strains were resistant to fluoroquinolones, but all were susceptible to fosfomycin (median MIC for Gram-negative pathogens 1.5 mg/L). In 25 patients, treatment was administered for 6 weeks, whereas in the remaining 19 patients it was prolonged to 12 weeks based on the presence of calcifications in the prostate. Cure rate was 82% at EOT and 80% and 73% at 3 and 6 months accordingly. Microbiological eradication was achieved in 86% and 77% at EOT and at 6 months, respectively. Failure was observed in 12 patients. The most common adverse event was diarrhoea (18%). CONCLUSIONS: Oral fosfomycin, particularly in the era of MDR prevalence, represents an attractive, safe and effective alternative to fluoroquinolones for the treatment of CBP.

RESUMEN

BACKGROUND: Prostatitis is a recurrent urinary infection in males and is often difficult to cure. The aim of the study was to examine whether anti-inflammatory effects of enhanced drainage of prostatic secretions, obtained through two months treatment with a proteolytic enzyme mucoactive (PEM) compound (Serrazyme and other constituents), influenced qualitative or quantitative expressions of bacterial growth in seminal cultures. METHOD: 450 patients with prostatitis syndromes were randomized either to PEM therapy (intervention group) or to no treatment group. All patients were followed at the end of a 2-month PEM continuous treatment period (T2) and further two months after withdrawal (T4). RESULTS: After treatment, 15 out of 107 (14.1%) patients with Chronic Bacterial Prostatitis (CBP) showed negative seminal cultures, while in patients with cat NIH-IIIA prostatitis seminal cultures became positive in 33.3% cases with low bacteriospermia. After two months from withdrawal, although among CBP patients the total number of isolates and colony forming units (CFU) counts showed not significant changes compared to matched-values observed at T2, microbial parameters varied significantly among inflammatory prostatitis patients. CONCLUSION: The results of the present study showed that 2 months of treatment with PEM, decreasing bacterial adherence and inflammatory prostatitis, reveals a subgroup of apparent inflammation associated with infection that microbial biofilms likely mask in inflammatory prostatitis patients.

RESUMEN

OBJECTIVE: To compare prostate volume and prostate-specific antigen (PSA) levels with bacterial growth in prostate tissue cultures. MATERIALS AND METHODS: Fifty male patients who underwent transurethral prostate resection were investigated prospectively. Resection chips from the prostate gland were added to brain-heart infusion medium and incubated. PSA levels were determined preoperatively at our urology ward. The prostate gland volume was estimated by transabdominal ultrasound examination preoperatively. RESULTS: Persons with positive bacterial prostate tissue cultures have a greater prostate volume. This is significant in patients with and without histopathologic signs of prostatitis. Persons with positive bacterial prostate tissue cultures have higher PSA values. This is significant in patients without histopathologic signs of prostatitis. CONCLUSION: People with positive bacterial prostatic tissue culture have a higher prostate volume in comparison with patients with negative culture findings and show a tendency toward increased PSA levels as well.

RESUMEN

The emergence of extended-spectrum ß-lactamase-producing Enterobacteriaceae (ESBL-E) infections requires re-assessment of therapeutic choices. Here we report the efficacy of cefoxitin-based antibiotic therapy for ESBL-E prostatitis. A prospective study including patients with ESBL-E prostatitis resistant to trimethoprim/sulfamethoxazole and fluoroquinolones from January 2014 to March 2016 was conducted. Cefoxitin was administered by continuous infusion for 3 weeks in the case of acute bacterial prostatitis or 6 weeks in the case of chronic bacterial prostatitis (CBP), with intravenous fosfomycin for the first 5 days. Urological investigations were performed to diagnose underlying urinary tract pathology. Clinical and microbiological efficacy were evaluated 3 months (M3) and 6 months (M6) after the end of therapy. A total of 23 patients were included in the study. The median patient age was 74 years (range 48-88 years). Of the 23 infections, 14 (61%) were CBP and 12 (52%) were healthcare-associated infections. The bacteria involved were Escherichia coli in 11 cases, Klebsiella pneumoniae in 10 cases and Klebsiella oxytoca in 2 cases. Clinical cure was observed in 19/23 patients (83%) at M3 and in 17/22 patients (77%) at M6. Urocultures were sterile in 13/23 patients (57%) at M3 and in 9/19 patients (47%) and M6. Urinary colonisation was observed in 6/19 patients (32%) with clinical cure at M3 and 5/14 patients (36%) with clinical cure at M6. No resistance to cefoxitin was detected. Surgical treatment was required for 7/23 patients (30%). In conclusion, cefoxitin-based antibiotic therapy is suitable for difficult-to-treat ESBL-E infections such as prostatitis.

RESUMEN

OBJECTIVE: To investigated the anti-inflammatory and antimicrobial effects of anthocyanins extracted from black soybean on the chronic bacterial prostatitis (CBP) rat model. METHODS: The Sprague-Dawley rats were divided into 4 groups, including control, ciprofloxacin, anthocyanins and anthocyanins with ciprofloxacin groups (n=8 in each group). Then, drip infusion of bacterial suspension (Escherichia coli Z17 O2:K1:H-) into Sprague-Dawley rats was conducted to induce CBP. In 4 weeks, results of prostate tissue, urine culture, and histological analysis on the prostate were analyzed for each group. RESULTS: The use of ciprofloxacin, anthocyanins, and anthocyanins with ciprofloxacin showed statistically significant decreases in bacterial growth and improvements in the reduction of prostatic inflammation compared with the control group (P<0.05). The anthocyanins with ciprofloxacin group showed a statistically significant decrease in bacterial growth and improvement in prostatic inflammation compared with the ciprofloxacin group (P<0.05). CONCLUSIONS: These results suggest that anthocyanins may have anti-inflammatory and antimicrobial effects, as well as a synergistic effect with ciprofloxacin. Therefore, we suggest that the combination of anthocyanins and ciprofloxacin may be effective in treating CBP to obtain a higher rate of treatment success.

RESUMEN

The present study examined the clinical pharmacokinetics of pazufloxacin in prostate tissue and estimated the probability of target attainment for tissue-specific pharmacodynamic goals related to treating prostatitis using various intravenous dosing regimens. Patients with prostatic hypertrophy received prophylactic infusions of pazufloxacin (500 mg, n = 23; 1000 mg, n = 25) for 0.5 h prior to transurethral prostate resection. Drug concentrations in plasma (0.5-5 h) and prostate tissue (0.5-1.5 h) were measured by high-performance liquid chromatography and used for subsequent noncompartmental and three-compartmental analysis. Monte Carlo simulation was performed to evaluate the probability of target attainment of a specific minimum inhibitory concentration (MIC) in prostate tissue: the proportion that achieved both area under the drug concentration over time curve (AUC)/MIC = 100 and maximum concentration (Cmax)/MIC = 8. Prostatic penetration of pazufloxacin was good with mean Cmax ratios (prostate tissue/plasma) of 0.82-0.99 and for AUC, 0.80-0.98. The probability of reaching target MIC concentrations in prostate tissue was more than 90% for dosing schedules of 0.25 mg/L for 500 mg every 24 h (500 mg daily), 0.5 mg/L for 500 mg every 12 h (1000 mg daily), 1 mg/L for 1000 mg every 24 h (1000 mg daily), and 2 mg/L for 1000 mg every 12 h (2000 mg daily). Importantly, the 2000 mg daily regimen of pazufloxacin produced a profile sufficient to have an antibacterial effect in prostate tissue against clinical isolates of Escherichia coli and Klebsiella pneumonia with MIC values less than 2 mg/L.

RESUMEN

OBJECTIVE: To investigate the effects of Ningmitai Capsules (NMT) combined with doxycycline hydrochloride (DH) on chronic prostatitis induced by Ureaplasma urealyticum (Uu). METHODS: This randomized controlled trial included 240 male patients with Uupositive chronic prostatitis, treated orally with NMT at 4 capsules tid (n= 35), DH at 100 mg bid (n = 78), and NMT+DH at the corresponding doses (n = 127), respectively, all for 2 successive weeks. At 1 week after drug withdrawl, we conducted routine urine analysis, EPS examination, and drug sensitivity test of the cultured Uu. RESULTS: The positivetonegative rate of Uu was significantly higher in the NMT+DH group than in the NMT and DH groups (89.0% [113/127] vs 54.3% [19/35] and 71.8% [56/78], P< 0.05), so were the cure rate (25.2% vs 20.0% and 20.5%, P< 0.05) and total effectiveness rate (89.0% vs 54.3% and 71.8%, P< 0.05). CONCLUSIONS: The combination of Ningmitai Capsules and doxycycline hydrochloride is more effective than either Ningmitai Capsules or doxycycline hydrochloride used alone in the treatment of Uupositive chronic prostatitis.

RESUMEN

The objectives of this study were to investigate risk factors and the incidence of ciprofloxacin resistance and extended-spectrum beta-lactamases (ESBL) in patients with acute bacterial prostatitis (ABP). We reviewed the medical records of 307 patients who were diagnosed with ABP between January 2006 and December 2015. The etiologic pathogens and risk factors for ciprofloxacin-resistant E. coli and ESBL-producing microbes, susceptibility to ciprofloxacin, and the incidence of ESBL in patients with ABP were described. History of prior urologic manipulation was an independent risk factor for ciprofloxacin-resistant (P = 0.005) and ESBL-producing microbes (P = 0.005). Advanced age (over 60 years) was an independent risk factor for ciprofloxacin-resistant microbes (P = 0.022). The ciprofloxacin susceptibility for Escherichia coli in groups without prior manipulation was documented 85.7%. For groups with prior manipulation, the susceptibility was 10.0%. Incidence of ESBL-producing microbes by pathogen was 3.8% for E. coli and 1.0% for Klebsiella pneumonia in the absence of manipulation group, and 20% and 33.3% in the presence of manipulation group, respectively. Initial treatment of ABP must consider patient's age and the possibility of prior manipulation to optimize patient treatment. With the high rate of resistance to fluoroquinolone, cephalosporins with amikacin, or carbapenems, or extended-spectrum penicillin with beta lactamase inhibitor should be considered as the preferred empirical ABP treatment in the patients with history of prior urologic manipulation.

RESUMEN

OBJECTIVE: To date, the management of patients with chronic bacterial prostatitis (CBP) is not satisfactory, especially in terms of symptoms relief. Here, we evaluated the efficacy and the safety of a combination of serenoa repens, selenium and lycopene extract + bromelain and methylsulfonylmethane extract associated with levofloxacin in patients with CBP. MATERIALS AND METHODS: All patients with clinical and instrumental diagnosis of CBP, admitted to a single Urological Institution from March to June 2015 were enrolled in this phase III study. All enrolled patients were randomized into two groups: Group A received levofloxacin 500 mg o.d. for 14 days associated with lycopene and methylsulfonylmethane; Group B received levofloxacin (500 mg o.d. for 14 days) only. Clinical and microbiological analyses were carried out at the time of admission (T0) and during the followups at 1 month (T1) and 6 months (T2) from the end of the treatment. NIH Chronic Prostatitis Symptom Index (CPSI), International Prostatic Symptom Score (IPSS) and Quality of Well-Being (QoL) questionnaires were used. The main outcome measures were the rate of microbiological cure and the improvement in questionnaire results from baseline at the end of the follow-ups period. RESULTS: Forty patients were enrolled in Group A and 39 in Group B. During the follow-up (T1), we recorded a significant changes in terms of NIH-CPSI and IPSS in Group A (mean difference: 17.6 ± 2.65; 12.2 ± 2.33; p < 0.01; p < 0.05, respectively) and versus Group B at the intergroup analysis (mean difference: -9 ± 1.82; -8.33 ± 1.71; p < 0.05; p < 0.05, respectively). No differences were reported in terms of microbiological findings between the two groups. At the second follow-up visit (T2), questionnaire results demonstrated statistically significant differences between groups (p < 0.001). One patient in Group A (2.5%) and 7 patients (17.9%) in Group B showed a symptomatic and microbiological recurrence (p = 0.02). CONCLUSIONS: The combination of serenoa repens, selenium, lycopene + bromelain and methylsulfonylmethane extracts improved the clinical efficacy of levofloxacin in patients affected by CBP without the development of side effects.

RESUMEN

UNLABELLED: The problem of the development of the new efficient methods for the treatment of the patients presenting with chronic bacterial vesiculitis (CBV) is currently considered among the important priorities. AIM: The objective of the present study was to provide a scientifically sound substantiation for the application of sinusoidal modulated currents (SMC), magnetic fields, and laser radiation in the combined treatment of the patients with CBV. PATIENTS AND METHODS: A total of 121 patients presenting with chronic bacterial vesiculitis were examined and treated during the latent phase of the inflammatory process. They were randomly divided into three groups. Group 1 (main) was comprised of 40 patients treated, in addition to basal pharmacotherapy, by supravascular contact laser irradiation of the cubital vein area followed after 2-3 hours by the application of sinusoidal modulated currents to the pubosacral region. Group 2 included 41patents given, besides basal pharmacotherapy, laser therapy in the same regimen as in group 1 supplemented after 2-3 hours by abdominal magnetic therapy. Group 3 (control) received traditional pharmacotherapy in the combination with antibacterial and anti-inflammatory medicines. RESULTS: It was demonstrated that the patients of group 2 exhibited the most pronounced positive dynamics of the clinical signs and symptoms estimated from the total National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) and of the characteristics of the quality of life evaluated based on the QLS scale. The patients of the two former groups experienced a more conspicuous decrease in the activity of the inflammatory process in seminal vesicles, restoration of their structural and anatomical features (as shown by the transrectal ultrasound study), improvement of testosterone metabolism, and normalization of the spermogram characteristics in comparison with controls. The analysis of the spermograms revealed the tendency toward the increase in the number of actively motile spermatozoa only in the patients of group 2. The combined treatment of the patients of the two former groups resulted in the decrease of the level of sex hormone-binding globulin and the increase of the free androgen index. CONCLUSION: The results of the study indicate that the application of the preformed physical factors for the treatment of the patients presenting with chronic bacterial vesiculitis enhances the effectiveness of pharmacotherapy and decreases both the frequency and the duration of relapses of the disease.

RESUMEN

OBJECTIVE: The aim of the study was to analyze the characteristics of patients with acute prostatitis presenting to the Emergency Department, the microbiological findings, antibiotic susceptibility, and bacteraemia associated factors. METHODS: Observational and cohort study with prospective follow-up including patients with acute prostatitis presenting to the Emergency Department from January-December 2012. Data were collected for demographic variables, comorbidities, microbiological findings, antibiotic treatment and outcome. RESULTS: Two hundred and forty one episodes of acute prostatitis were included. Mean age was 62.9 ± 16 years, a history of prostate adenoma was reported in 54 cases (22.5%) and prior manipulation of the lower urinary tract in 40 (17%). Mean symptoms duration was 3.38 ± 4.04 days, voiding symptoms were present in 176 cases (73%) and fever in 154 (64%). Seventy patients (29%) were admitted to the hospital and 3 died. From 216 urine cultures, 128 were positive (59%) and 24 (17.6%) out of 136 blood cultures. Escherichia coli was the main pathogen (58.6% of urine cultures and 64% of blood cultures) with resistant strains to fluoroquinolones, cotrimoxazole and amoxicillin/clavulanic in 27.7%, 22.9% and 27.7% of cases respectively. In the univariate analysis, only chills were associated to bacteraemia (p=0.013). At 30-day follow-up, patients with bacteraemia returned more frequently to the Emergency Department (p=0.037) and were more often admitted to the hospital (p=0.003). CONCLUSIONS: Patients with acute prostatitis discharged from the Emergency Department need clinical follow-up and monitoring of microbiological findings in order to assure an adequate antibiotic treatment. Return to Emergency Department and admission to the hospital were significantly more frequent among patients with bacteraemia.

RESUMEN

This is a retrospective study of 15 difficult-to-treat (i.e., exhibiting previous failure, patient side effects, or resistance to ciprofloxacin and co-trimoxazole) chronic bacterial prostatitis infections (5 patients with multidrug-resistant Enterobacteriaceae [MDRE]) receiving fosfomycin-tromethamine at a dose of 3 g per 48 to 72 h for 6 weeks. After a median follow-up of 20 months, 7 patients (47%) had a clinical response, and 8 patients (53%) had persistent microbiological eradication; 4/5 patients with MDRE isolates achieved eradication. There were no side effects. Fosfomycin-tromethamine is a possible alternative therapy for chronic bacterial prostatitis.

RESUMEN

For chronic bacterial prostatitis, there are few oral antibiotics available that are active against common uropathogens and are able to penetrate the non-inflamed prostate at therapeutic concentrations. Oral options to treat chronic prostatitis due to Gram-negative bacillary multidrug-resistant organisms are even more limited. We report a case of persistent extended-spectrum ß-lactamase (ESBL)-positive Escherichia coli chronic prostatitis refractory to antibiotic therapy. Prolonged courses of fosfomycin failed to eradicate the infection. Re-treatment with high-dose fosfomycin again failed to clear the infection. After repeated courses of fosfomycin, the ESBL-positive E. coli remained susceptible to fosfomycin. Transrectal ultrasound revealed prostatic calcifications that were thought to be the reason for antibiotic failure. Following transurethral resection of the prostate (TURP) to remove the prostatic calcifications, the prostatic calcifications remained and the infection persisted. Although the patient's ESBL-positive E. coli was resistant to doxycycline, he was treated with a combination of fosfomycin plus doxycycline. Treatment with fosfomycin and doxycycline rapidly cured his chronic prostatitis.

RESUMEN

BACKGROUND: Prostatic inflammation has been suggested to contribute to the etiology of lower urinary tract symptoms by inducing fibrosis. We previously used a well-characterized mouse model of bacterial-induced prostate inflammation to demonstrate that chronic prostatic inflammation induces collagen deposition. Here, we examined stability of the newly synthesized collagen in bacterial-induced prostatic inflammation and the reversibility of fibrosis after resolution of infection and inflammation. METHODS: Uropathogenic Escherichia coli 1677 was instilled transurethrally into adult C3H/HeOuJ male mice to induce chronic prostatic inflammation. Collagen was labeled by (3) H-proline administration for 28 days post-inoculation and (3) H-hydroxyproline incorporation measured to determine stability of the newly synthesized collagen. Inflammation score was graded using a previously established system and total collagen content was measured by picrosirius red staining quantitation and hydroxyproline content. Resolution of inflammation and reversal of collagen deposition was assessed after treatment with antibiotic enrofloxacin for 2 weeks on day 28 post-inoculation followed by an 8-week recovery period. RESULTS: Decay analysis of incorporated (3) H-hydroxyproline revealed the half-life of newly synthesized collagen to be significantly shorter in infected/inflamed prostates than in controls. Treatment with antibiotic enrofloxacin completely eradicated bacterial infection and allowed resolution of inflammation. This was followed by marked attenuation of collagen content and correlation analysis verified a positive association between the resolution of inflammation and the reversal of collagen deposition. CONCLUSIONS: These data demonstrate, for the first time, that inflammation-induced prostatic fibrosis is a reversible process.
