ABSTRACT
PURPOSE: Liver abscesses concomitant with acute prostatitis are rare and potentially fatal. We analyzed the occurrence of this condition and clinical characteristics of the affected patients. MATERIALS AND METHODS: The medical records of 474 patients diagnosed with acute prostatitis between June 2006 and July 2022 were retrospectively reviewed. Patients in whom pathogens were not detected in serum or urine cultures were excluded. A total of 271 patients were included in the analysis. Patient characteristics and laboratory test results were compared between patients with acute prostatitis with and without liver abscesses. RESULTS: Fifteen patients (5.5%) were identified with simultaneous liver abscesses and acute prostatitis. The liver abscess group was younger than the non-liver abscess group in terms of mean age. In the univariate analysis, a high proportion of patients had diabetes mellitus, whereas a low proportion had hypertension. None of the underlying diseases, including benign prostatic hyperplasia, malignancy, or alcoholism, demonstrated a significant association with liver abscess in multivariate analysis; however, an association was observed in liver function test results. All patients with liver abscesses tested positive for Klebsiella pneumoniae. CONCLUSIONS: When K. pneumoniae is identified in patients with acute prostatitis and abnormal liver function tests, considering the possibility of metastatic infection in other organs, including the liver, and performing an active evaluation is essential.

Salmonella is a rod-shaped gram-negative bacterium of the family Enterobacteriaceae, commonly present in the gastrointestinal tract in humans and animals. Salmonella-associated bacteriuria and prostatitis are rare but have been reported in humans, predominantly older patients with underlying diseases, including urinary tract obstructions, diabetes mellitus, and compromised immunity. In dogs, Salmonella bacteriuria and prostatitis have only been described in patients on immunosuppressive medications. This study reports the case of a 7 yr old male Pit bull terrier mix with Salmonella prostatitis. The patient had a 3 day history of lethargy and anorexia. He was fed a commercial diet and had no previous medical or medication history. On physical examination, he had caudal abdominal pain and a firm, enlarged, painful prostate. Ultrasound revealed marked prostatomegaly with multifocal echogenic fluid-filled cavitations and regional peritonitis. Urine and prostatic fluid culture grew Salmonella (>100,000 colony-forming units/mL) using standard culture methods. Treatment with enrofloxacin was initiated for 8 wk. Repeat urine and prostatic cultures after cessation of antibiotics were negative, and serial fecal cultures were Salmonella negative. This case report is, to the best of our knowledge, the first to describe Salmonella prostatitis and bacteriuria in an immunocompetent dog who was not fed a raw diet.

The human gut microbiome (GM) impacts various physiological processes and can lead to pathological conditions and even carcinogenesis if homeostasis is disrupted. Recent studies have indicated a connection between the GM and prostatic disease. However, the underlying mechanisms are still unclear. This review aims to provide a summary of the existing information regarding the connection between the GM and various prostatic conditions such as chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), benign prostatic hyperplasia (BPH), and prostate cancer (PCa). Furthermore, the review aims to identify possible pathogenic mechanisms and suggest potential ways of targeting GM to prevent and treat prostatic disease. Due to the complexity of the mechanism between GM and prostatic diseases, additional research is required to comprehend the association between the two. This will lead to more effective treatment options for prostatic disease.

To detect and analyze the changes of microorganisms in expressed prostatic secretion (EPS) of patients with IIIB prostatitis before and after low-intensity pulsed ultrasound (LIPUS) treatment, and to explore the mechanism of LIPUS in the treatment of chronic prostatitis (CP). 25 patients (study power was estimated using a Dirichlet-multinomial approach and reached 96.5% at α = 0.05 using a sample size of 25) with IIIB prostatitis who were effective in LIPUS treatment were divided into two groups before and after LIPUS treatment. High throughput second-generation sequencing technique was used to detect and analyze the relative abundance of bacterial 16 s ribosomal variable regions in EPS before and after treatment. The data were analyzed by bioinformatics software and database, and differences with P < 0.05 were considered statistically significant. Beta diversity analysis showed that there was a significant difference between groups (P = 0.046). LEfSe detected four kinds of characteristic microorganisms in the EPS of patients with IIIB prostatitis before and after LIPUS treatment. After multiple comparisons among groups by DESeq2 method, six different microorganisms were found. LIPUS may improve patients' clinical symptoms by changing the flora structure of EPS, stabilizing and affecting resident bacteria or opportunistic pathogens.

ABSTRACT: FDG PET/CT is a well-documented imaging investigation to evaluate fever of unknown origin (FUO). Brucellosis is one of the causes of FUO, which can be missed as it requires a longer incubation period for growth on culture media. Rarely, it can involve the prostate. Here, we present a case of FUO with initial negative blood and urine cultures and no localizing signs or symptoms. 18F-FDG PET/CT revealed hypermetabolism in the prostate and seminal vesicles. A repeat blood and urine culture showed the growth of Brucella species after 5 days of incubation, and the patient responded to Brucella-directed antibiotic therapy.

BACKGROUND: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is very common worldwide, and alcohol consumption is a notable contributing factor. Researches have shown that gut microbiota can be influenced by alcohol consumption and is an important mediator in regulating Th17 cell immunity. However, it is still unclear the exact mechanism by which alcohol exacerbates the CP/CPPS and the role of gut microbiota in this process. METHOD: We first constructed the most-commonly used animal model for CP/CPPS, the experimental autoimmune prostatitis (EAP) model, through immunoassay. Based on this, mice were divided into EAP group and alcohol-consuming EAP group. By 16S rRNA sequencing and non-targeted metabolomics analysis, differential gut microbiota and their metabolites between the two groups were identified. Subsequently, metabolomics detection targeting cholesterols was carried out to identify the exact difference in cholesterol. Furthermore, multiple methods such as flow cytometry and immunohistochemistry were used to detect the differentiation status of Th17 cells and severity of prostatitis treated with 27-hydroxycholesterol (the differential cholesterol) and its upstream regulatory factor-sterol regulatory element-binding protein 2 (SREBP2). Lastly, fecal transplantation was conducted to preliminary study on whether alcohol intake exacerbates EAP in immune receptor mice. RESULTS: Alcohol intake increased the proportion of Th17 cells and levels of related inflammatory factors. It also led to an altered gut bacterial richness and increased gut permeability. Further metabolomic analysis showed that there were significant differences in a variety of metabolites between EAP and alcohol-fed EAP mice. Metabolic pathway enrichment analysis showed that the pathways related to cholesterol synthesis and metabolism were significantly enriched, which was subsequently confirmed by detecting the expression of metabolic enzymes. By targeting cholesterol synthesis, 27-hydroxycholesterol was significantly increased in alcohol-fed EAP mice. Subsequent mechanistic research showed that supplementation with 27-hydroxycholesterol could aggravate EAP and promote Th17 cell differentiation both in vivo and in vitro, which is regulated by SREBP2. In addition, we observed that fecal transplantation from mice with alcohol intake aggravated EAP in immunized recipient mice fed a normal diet. CONCLUSION: Our study is the first to show that alcohol intake promotes Th17 cell differentiation and exacerbates EAP through microbiota-derived cholesterol biosynthesis.

ABSTRACT: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is highly prevalent worldwide and poses a significant threat to men's health, particularly affecting young men. However, the exact causes and mechanisms behind CP/CPPS remain unclear, leading to challenges in its treatment. In this research, a CP/CPPS rat model was established with complete Freund's adjuvant (CFA), and berberine hydrochloride was administered through daily gavage to assess its therapeutic effects. The alterations in the gut microbiome induced by CP/CPPS and berberine hydrochloride were investigated through 16S ribosomal RNA sequencing of cecum content and colonic epithelial cells. To investigate the impact of the gut microbiome on CP/CPPS, a pseudo germ-free rat model was established, and fecal microbiome transplantation (FMT) was performed on these rats. In all, berberine hydrochloride demonstrated effective reduction of inflammation and oxidative stress in the prostate, offering significant therapeutic advantages for CP/CPPS. Through analysis of the gut microbiome using 16S ribosome RNA sequencing, distinct differences were observed between CP/CPPS rats and control rats, and Clostridium butyricum was identified as a key bacteria. Pseudo germ-free rats that underwent FMT from CP/CPPS rats or rats treated with berberine hydrochloride displayed varying levels of inflammatory cytokine production, oxidative stress, and activity of associated signaling pathways. In conclusion, the therapeutic potential of berberine hydrochloride in addressing CP/CPPS is highly significant. The gut microbiome has emerged as a critical factor in the development of CP/CPPS and plays a pivotal role in mediating the therapeutic effects of berberine hydrochloride.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common pelvic pain syndrome in males, seriously affecting patients' quality of life. For a long time, CP/CPPS has been considered a complex and variable disease, and its pathogenesis remains incompletely understood. Currently, CP/CPPS is believed to be a group of diseases characterized by pelvic pain or discomfort, urinary abnormalities, and other symptoms, each with its unique etiology, clinical characteristics, and outcomes, likely resulting from the action of pathogens or (and) certain non-infectious factors. Traditionally, CP/CPPS was thought to be unrelated to bacterial infections. However, in recent years, with the development of microbiology and the advancement of high-throughput sequencing technology, an increasing number of studies have suggested that microorganisms in the reproductive system may play an important role in the pathogenesis of CP/CPPS. The unique characteristics of CP/CPPS, such as its refractory nature and tendency to recur, may be closely related to the microbiota and their biological functions in the reproductive system. The relationship between CP/CPPS and reproductive system microorganisms is one of the current hot topics in microbiology and urology, receiving considerable attention from scholars in recent years and making a series of new advances. Through this review, we will comprehensively explore the relationship between CP/CPPS and reproductive system microorganisms, and look forward to future research directions, aiming to provide new ideas and methods for clinical diagnosis and treatment, thereby improving the treatment outcomes and quality of life of CP/CPPS patients.

BACKGROUND Urogenital bacterial infections have a high incidence in humans. The most frequent cause of infections of the urogenital tract is gram-negative bacteria. Antibiotics are very effective in curing infectious diseases but they are accompanied by health complications. Probiotics are live microorganisms that are believed to confer a beneficial effect on human health when consumed in adequate amounts. This study aimed to compare outcomes from antibiotic treatment with and without the use of probiotics in 897 patients with lower urogenital tract infections, including cystitis, urethritis, prostatitis, and vulvovaginitis. MATERIAL AND METHODS A total of 897 patients aged 18 to 55 years were included in this research. Patients were divided into an intervention group including 460 patients (254 women, 206 men) and a comparison group including 437 patients (240 women, 197 men). The probiotics received by patients were capsules of ProBalans®. The diagnosis of cystitis, urethritis, prostatitis, vulvovaginitis, and sexually transmitted infection was done using several tests, and antibiotics were used for treatment. Qualitative data were analyzed using the chi-square or Fisher exact test. RESULTS We found a significant difference regarding patients' impressions of improvement after therapy between patients in the intervention group and the comparison group. CONCLUSIONS Use of probiotics together with antibiotics in the treatment of urogenital tract infection can help to reduce the adverse effects of antibiotics, increase the efficiency of antibiotic therapy, and reduce bacterial resistance to antibiotics. However, further research is needed to confirm these potential health benefits.

BACKGROUND: Chronic infection and inflammation have been linked to the development of prostate cancer. Dysbiosis of the oral and gut microbiomes and subsequent microbial translocation can lead to pathogenic prostate infections. Microbial-produced metabolites have also been associated with signaling pathways that promote prostate cancer development. A comprehensive discussion on the mechanisms of microbiome infection and the prostate microenvironment is essential to understand prostate carcinogenesis. METHODS: Published studies were used from the National Center for Biotechnology Information (NCBI) database to conduct a narrative review. No restrictions were applied in the selection of articles. RESULTS: Microbiome-derived short-chain fatty acids (SCFAs) have been found to upregulate multiple signaling pathways, including MAPK and PI3K, through IGF-1 signaling and M2 macrophage polarization. SCFAs can also upregulate Toll-like receptors, leading to chronic inflammation and the creation of a pro-prostate cancer environment. Dysbiosis of oral microbiota has been correlated with prostate infection and inflammation. Additionally, pathogenic microbiomes associated with urinary tract infections have shown a link to prostate cancer, with vesicoureteral reflux potentially contributing to prostate infection. CONCLUSIONS: This review offers a comprehensive understanding of the impact of microbial infections linked to intraprostatic inflammation as a causative factor for prostate cancer. Further studies involving the manipulation of the microbiome and its produced metabolites may provide a more complete understanding of the microenvironmental mechanisms that promote prostate carcinogenesis.

It is estimated that microorganisms colonize 90% of the body surface. In some tracts, such as the genitourinary tract, the microbiota varies throughout life, influenced by hormonal stimulation and sexual practices. This study evaluated the semen differences and presence of Lactobacillus crispatus, Lactobacillus iners, Gardnerella vaginalis and Atopobium vaginae in semen samples from patients with symptoms of chronic prostatitis and men asymptomatic for urogenital infections. Fifty-three semen samples were included: 22 samples from men with symptoms of chronic prostatitis and 31 asymptomatic men (control group). In addition to the presence of L. crispatus, L. iners, G. vaginalis and A. vaginae, semen parameters, total antioxidant capacity of seminal plasma, prostatic antigen and some proinflammatory cytokines were evaluated in each semen sample. Volunteers with symptoms of chronic prostatitis presented a lower percentage of sperm morphology (4.3% vs. control group 6.0%, p = 0.004); in the semen samples of volunteers in the group asymptomatic for urogenital infections, microorganisms associated with the vaginal microbiota were detected more frequently. The presence of bacteria in the vaginal microbiota can also benefit male reproductive health, which undergoes various modifications related to lifestyle habits that are susceptible to modification. Microorganisms associated with the vaginal microbiota, such as L. crispatus, L. iners, G. vaginalis and A. vaginae, may have a protective role against the development of male genitourinary diseases such as prostatitis.

INTRODUCTION: This study aims to show the bacteriologic picture of acute prostatitis and bacteremia caused by infective agent after transrectal ultrasound-guided prostate biopsy (TRUSBx) and to determine the resistance rates of the infections in patients undergoing transrectal biopsy and to guide prophylaxis approach before biopsy. METHODOLOGY: The retrospective data of 935 patients who underwent TRUSBx between January 2010 to January 2019 were reviewed. Pre-biopsy urine cultures and antimicrobial susceptibility were obtained. Subsequently, patients admitted to the hospital with any complaint after biopsy were examined for severe infection complications. RESULTS: Of the 430 (61.7%) patients who underwent urine culture before the procedure, 45 (10.5%) had growth; 30 (66.7%) of the growing microorganisms were Escherichia coli. Twenty (44.4%) of all Gram-negative agents in pre-biopsy urine culture were susceptible to quinolone. Post TRUSBx bacteremia was present in 18.2%, urinary system infection in 83.6%, and hospitalization in 61.8% of 55 patients who were admitted to the hospital. In the isolated gram-negative microorganisms, fluoroquinolones resistance in urinary system infections was seen in 40% and bacteremia was seen in 70% of the cases. ESBL-producing Gram-negative bacteria were determined in 40% of infections in blood and 38.5% of urinary system infections in the post biopsy period in the current study. CONCLUSIONS: These high antibiotic resistance rates suggest that we better review our pre-procedure prophylaxis approaches.

BACKGROUND: Recent studies demonstrated that chronic prostatitis (CP) is closely related to the gut microbiota (GM). Nevertheless, the causal relationship between GM and CP has not been fully elucidated. Therefore, the two-sample Mendelian randomization (MR) analysis was employed to investigate this association. METHODS: The summary data of gut microbiota derived from a genome-wide association study (GWAS) involving 18,340 individuals in the MiBioGen study served as the exposure, and the corresponding summary statistics for CP risk, representing the outcome, were obtained from the FinnGen databases (R9). The causal effects between GM and CP were estimated using the inverse-variance weighted (IVW) method supplemented with MR-Egger, weighted median, weighted mode, and simple mode methods. Additionally, the false discovery rate (FDR) correction was performed to adjust results. The detection and quantification of heterogeneity and pleiotropy were accomplished through the MR pleiotropy residual sum and outlier method, Cochran's Q statistics, and MR-Egger regression. RESULTS: The IVW estimates indicated that a total of 11 GM taxa were related to the risk of CP. Seven of them was correlated with an increased risk of CP, while the remained linked with a decreased risk of CP. However, only Methanobacteria (OR 0.86; 95% CI 0.74-0.99), Methanobacteriales (OR 0.86; 95% CI 0.74-0.99), NB1n (OR 1.16; 95% CI 1.16-1.34), Methanobacteriaceae (OR 0.86; 95% CI 0.74-0.99), Odoribactergenus Odoribacter (OR 1.43; 95% CI 1.05-1.94), and Sutterellagenus Sutterella (OR 1.33; 95% CI 1.01-1.76) still maintain significant association with CP after FDR correction. Consistent directional effects for all analyses were observed in the supplementary methods. Subsequently, sensitivity analyses indicated the absence of heterogeneity, directional pleiotropy, or outliers concerning the causal effect of specific gut microbiota on CP (p > 0.05). CONCLUSION: Our study demonstrated a gut microbiota-prostate axis, offering crucial data supporting the promising use of the GM as a candidate target for CP prevention, diagnosis, and treatment. There is a necessity for randomized controlled trials to validate the protective effect of the linked GM against the risk of CP, and to further investigate the underlying mechanisms involved.

BACKGROUND: Even if Meares-Stamey 4-glass (M&S) test is regarded a decisive tool for diagnosing prostatitis its use is only rarely performed in everyday clinical practice. Here, we analyze if the diagnostic yield of the M&S test could be improved by a pre-test categorization of patients due to undergo a M&S test. METHODS: All clinical and microbiological data of patients who underwent M&S test in two urological centers from January 2004 to December 2021 were analyzed in this retrospective cohort study. One center has a dedicated staff member for the study of prostatitis (Cohort I), while the other center is a general urological unit (Cohort II). All patients were divided into 3 groups on the basis of the assembled data: patients with symptoms related to prostatitis only (Group I), patients with symptoms related to both prostatitis and BPH (Group II), patients with symptoms related to BPH only (Group III). The rates of positive microbiological results in each group were compared. RESULTS: In the whole period, 9347 patients were analyzed and categorized as follows: Group I, 1884; Group II, 5151; Group III, 2312. Three-thousand and eight-hundred twenty-three patients showed positive culture results (40.9%). The most common isolated species was Escherichia coli (49.7%), followed by Enteroccus spp. (31.8%). The rates of positive M&S tests in the different symptom groups were: Group I, 1532 (81.4%); Group II, 1494 (29.0%); Group III, 797 (34.4%). The overall rate of positive M&S tests in each urology center showed that the center with a staff member who is dedicated to prostatitis studies (Cohort I) had a significantly higher rate of positive M&S tests than the general urological department (Cohort II) (64.3% vs 31.4%; p < 0.001). CONCLUSIONS: Symptom-based patient selection and dedicated staff members will increase the diagnostic yield of the M&S test and reduce the number of unnecessary tests.

Prostatitis is a major urological disease affecting 25%-50% of men over their lifetime. However, prostatitis is often overlooked in nonurologic departments due to its sometimes indeterminate symptoms. In this review, we describe how to recognize and treat acute bacterial prostatitis, which manifests as a clinical problem in other departments as well as urology, to help prevent this disease from being overlooked. There are several possible negative effects of not recognizing acute bacterial prostatitis (ABP). First, initial treatment can fail. In the hyperacute phase, common antibiotics are often effective, but in rare cases, such antibiotics may not be effective. In addition, once ABP progresses to form a prostate abscess, potentially avoidable surgical interventions are often needed. A second issue is the transition to chronic prostatitis. If chronic bacterial prostatitis progresses, treatment requires long-term antibiotic administration and the response rate is not high. Some patients may have to deal with urinary tract infections for the rest of their lives. Finally, there is the problem of overlooking the underlying disease. ABP is rare in healthy adult men without underlying disease, including sexually transmitted diseases as well as benign prostatic hyperplasia, urinary stones, and malignant tumors, and may not be obvious. When examining patients with fever of unknown origin, it is necessary to exclude not only infectious diseases but also collagen diseases and malignant tumors. If there are any doubts, we recommend a rectal exam and consultation with a urologist.

Objectives: The importance of Gram-positive microorganisms and atypical bacteria in chronic bacterial prostatitis (CBP) has recently been described. For this reason, this study analyzes the etiology of CBP, as well as the evolution of antibiotic resistance through a systematic review. Material and methods: A systematic review of studies obtained through the MEDLINE (PubMed) database, related to the etiology and antibiotic resistance profile of CBP, published up July 1, 2021. Results: The most frequent isolated microorganisms that we have found in publications are Enterococcus faecalis (46.90%), Staphylococcus spp. (22.30%), Escherichia coli (15.09%) and atypical bacteria (6.04%). Conclusions: CBP is undergoing and unprecedented change of paradigm. Gram-positive bacteria and atypical bacteria are the main pathogens involved in the aetiology of this entity. This forces us to rethink the therapeutic strategy used, since it is necessary to use antibiotics that assume the etiological change and the profile of antibiotic resistance described. (AU)

Por ello, en este estudio se analiza la etiología de la PCB, así como la evolución de la resistencia antibiótica a través de una revisión sistemática. Material y métodos: Se ha realizado una revisión sistemática de estudios obtenidos a través de la base de datos MEDLINE (PubMed), relacionados con la etiología y el perfil de resistencia antibiótica de la PCB, publicados con anterioridad al 1 de julio de 2021. Resultados: Los principales microorganismos aislados en los estudios incluidos en la revisión fueron Enterococcus faecalis (46,90%), Staphylococcus spp. (22,30%), Escherichia coli (15,09%) y bacterias atípicas (6,04%). Conclusiones: La PCB está experimentando un cambio de paradigma, ya que las bacterias grampositivas y las atípicas se erigen como los principales agentes causales de esta entidad. Esto obliga a replantear la estrategia terapéutica utilizada, pues es necesario utilizar antibióticos que asuman el viraje etiológico y el perfil de resistencias antibióticas descrito. (AU)

OBJECTIVE: Chronic bacterial prostatitis (CBP) is an entity of difficult clinical diagnosis and treatment, being the microbiological study of semen the main diagnostic test. This study aimed to determine the etiology and antibiotic resistance in patients with symptomatic bacteriospermia (SBP) in our environment. METHODS: A cross-sectional and retrospective descriptive study has been carried out from a Regional Hospital of the Spanish Southeast. The participants were patients assisted in the consultations of the Hospital with clinic compatible with CBP, between 2016 and 2021. The interventions were collection and analysis of the results derived from the microbiological study of the semen sample. The main determinations were the etiology and rate of antibiotic resistance of BPS episodes are analyzed. RESULTS: The main isolated microorganism is Enterococcus faecalis (34.89%), followed by Ureaplasma spp. (13.74%) and Escherichia coli (10.98%). The rate of antibiotic resistance of E. faecalis to quinolones (11%) is lower than previous studies, while for E. coli it has been higher (35%). The low rate of resistance shown by E. faecalis and E. coli to fosfomycin and nitrofurantoin stands out. CONCLUSIONS: In the SBP, gram-positive and atypical bacteria are established as the main causative agents of this entity. This forces us to rethink the therapeutic strategy used, which will avoid the increase in antibiotic resistance, recurrences, and chronicity of this pathology.
