All following incubations were performed at +37C for 1 hour. papillomavirus (HPV) 6, 11, 16, 18, Balicatib 31 and 33, herpes simplex virus (HSV) 1 and 2, human cytomegalovirus (CMV), Chlamydia trachomatis, Mycoplasma hominis, Ureaplasma urealyticum, Neisseria gonorrhoeae and Treponema pallidum. Antibody seroprevalence and mean serum antibody levels were compared between cases and controls. Tumour grade and stage were correlated with serological findings. Results PCa patients were more likely to harbour antibodies against Ureaplasma urealyticum (odds ratio (OR) 2.06; 95% confidence interval (CI) 1.08-4.28). Men with BPH were more often seropositive for HPV 18 and Chlamydia trachomatis (OR 0.23; 95% CI 0.09-0.61 and OR 0.45; 95% CI 0.21-0.99, respectively) and had higher mean serum CMV antibody levels than PCa patients (p = 0.0004). Among PCa patients, antibodies against HPV 6 were associated with a higher Gleason score (p = 0.0305). Conclusions Antibody seropositivity against the analyzed pathogens with the exception of Ureaplasma does not seem to be a risk factor for PCa pathogenesis. The presence or higher levels of serum antibodies against the genitourinary pathogens studied were not consistently associated with PCa. Serostatus was not a predictor of disease stage in the studied population. Balicatib Background Prostate cancer (PCa) is one of the most important health issues in the aging male population, especially in the industrialized Western world. In the EU in 2006, it accounted for approximately 20% of all noncutaneous cancers [1]. In the United States, 217.730 new cases were estimated to occur in 2010 2010 (28% of all new cancer cases in men except for basal and squamous cell skin carcinomas) and 32.050 men were expected to die from PCa (11% of all cancer-related deaths) [2]. Research around the etiology of human cancer has found evidence for 15-20% of them being caused by an infectious agent. Whether PCa or at least a subgroup of PCa cases are associated with infection has been a matter of debate since the 1970 s. With the widespread use of sophisticated serological assays and molecular biology methods for the detection of infectious brokers in tissue, several studies have been published in the past two decades giving a better insight into the matter. Many of them have focused on a single pathogen only [3-9]. We have conducted an epidemiological study of several most common genitourinary pathogens among PCa and benign prostate hyperplasia (BPH) patients. The aim of the study was to elucidate whether the prevalence of antibody seropositivity and/or antibody levels differ between these two groups of patients. We hypothesized that elevated serum antibody levels or higher seroprevalence in PCa patients would suggest an association of genitourinary contamination in patient history and elevated Balicatib PCa risk. Methods Study population This is a hospital-based case-control study. The study population consisted of a total of 434 Caucasian males who had been treated with open prostate surgery in the Department of Urology of the 3rd Faculty of Medicine, Charles University in Prague in the period 2004-2010. The institution is a public hospital with a nonselective admission policy based on a defined catchment area. Patients underwent open radical retropubic prostatectomy (RRP) modified by Reiner and Walsh [10,11] for clinically localized PCa or simple transvesical prostatectomy (SP) Rabbit polyclonal to ADORA1 as described by Fuller and Culp [12,13] for BPH. No transurethral resection of the prostate (TURP) or needle-biopsy specimens were used in the study as both methods only deliver so little tissue that small foci of PCa can be missed. In 5 cases, percutaneous cystolithotripsy was performed along with SP. All patients were free of urinary tract contamination symptoms and had a negative urine culture at the.
