trimethoprim--sulfamethoxazole-drug-combination and Prostatic-Neoplasms

Transurethral resection of the prostate (TURP) and Greenlight laser vaporisation (GL) of the prostate are frequently performed urological procedures. For TURP, a single-dose antimicrobial prophylaxis (AP) is recommended to reduce postoperative urinary tract infections. So far, no international recommendations for AP have been established for GL. In a survey-based study in Switzerland, Germany and Austria, urologists reported routinely extending AP primarily for 3 days after both interventions. We therefore aim to determine whether single-dose AP with cotrimoxazole is non-inferior to 3-day AP with cotrimoxazole in patients undergoing TURP or GL of the prostate.. We will conduct an investigator-initiated, multicentre, randomised controlled trial. We plan to assess the non-inferiority of single-dose AP compared to 3-day AP. The primary outcome is the occurrence of clinically diagnosed symptomatic urinary tract infections which are treated with antimicrobial agents within 30 days after randomisation. The vast majority of collected outcomes will be assessed from routinely collected data. The sample size was estimated to be able to show the non-inferiority of single-dose AP compared to 3-day AP with at least 80% power (1 - β = 0.8) at a significance level of α = 5%, applying a 1:1 randomisation scheme. The non-inferiority margin was determined in order to preserve 70% of the effect of usual care on the primary outcome. For an assumed event rate of 9% in both treatment arms, this resulted in a non-inferiority margin of 4.4% (i.e. 13.4% to 9%). To prove non-inferiority, a total of 1574 patients should be recruited, in order to have 1416 evaluable patients. The study is supported by the Swiss National Science Foundation.. For AP in TURP and GL, there is a large gap between usual clinical practice and evidence-based guidelines. If single-dose AP proves non-inferior to prolonged AP, our study findings may help to reduce the duration of AP in daily routine-potentially reducing the risk of emerging resistance and complications related to AP..

The complications of prostate needle biopsy (PNB) are important when considering the benefits and harms of prostate cancer screening. Studies from the United States and Canada have recently reported increasing numbers of hospitalizations for infectious complications after PNB.. Examine the risk of infectious complications and hospital admissions after PNB in a European screening trial.. From 1993 to 2011, 10 474 PNBs were performed in the European Randomized Study of Screening for Prostate Cancer (Rotterdam section). Prophylaxis originally consisted of trimethoprim-sulfamethoxazole. Beginning in 2008, it was changed to ciprofloxacin.. Febrile complications and hospital admissions were assessed by questionnaires 2 wk after PNB. Logistic regression was used to identify risk factors for biopsy-related fever and hospital admission.. Fever and hospital admission were reported on 392 of 9241 questionnaires (4.2%) and 78 of 9198 questionnaires (0.8%), respectively. Although most fevers were managed on an outpatient basis, 81% of hospital admissions were for infection. Of the 56 available blood cultures, 34 were positive with Escherichia coli as the predominant organism. On multivariable analysis, prostate enlargement and diabetes were significantly associated with an increased risk of fever after PNB, whereas later year of biopsy was the only factor significantly associated with an increased risk of hospital admission.. In a European screening trial, <5% PNBs resulted in febrile complications. Significant risk factors included diabetes and prostatic enlargement. Although most fevers were managed on an outpatient basis, infection remained the leading cause of hospital admission after PNB. Consistent with prior international reports, the frequency of hospital admissions after PNB significantly increased over time. Nevertheless, the absolute frequency of hospital admissions related to PNB was low and should not dissuade healthy men who would benefit from early prostate cancer diagnosis from undergoing biopsy when clinically indicated.

A standard protocol for perioperative antibiotic prophylaxis in radical retropubic prostatectomy has not been established until now. The present pilot study compared the perioperative single-dose of piperacillin/tazobactam to the administration of ciprofloxacin or cotrimoxazol for 5 days with regard to postoperative infections. For the first time these antibiotic regimes were described in radical retropubic prostatectomy.. The patients were divided into three groups, each consisting of 17 patients: group 1: a single-dose of piperacillin / tazobactam 4.5 g i. v., group 2: ciprofloxacin 500 mg or cotrimoxazol 960 mg i. v. / p. o. and group 3: varying administration and duration of different kinds of antibiotics as control group. The basic characteristics of the patients such as age, body-mass-index, risk factors, diseases, former surgeries and medication were similar between all three groups. Also there were no significant differences in intraoperative parameters such as operation time, blood loss and other postoperative complications.. The piperacillin / tazobactam group showed a significantly lower body temperature on postoperative days (POD) 1-3. The laboratory values were not significantly different among the groups, except the piperacillin / tazobactam group showed a significantly lower CRP level on POD 1-3 than group 3. All antibiotic regimes could afford an efficient protection: None of the patients died and there were no cases of serious consequences such as pneumonia, urosepsis or bacteriuria. Although not statistically significant, the piperacillin / tazobactam group showed better clinical outcomes: here the length of hospitalisation was two days less than in the other groups, no cases of wound infection occurred, the antimicrobial resistance rates were lower and fewer patients were treated with antibiotics in the postoperative course.. Comparable to similar studies with a larger number of patients our pilot study demonstrated, although statistically not significant, better clinical results overall. We therefore conclude that a single-dose of piperacillin / tazobactam appears to be an efficient antibiotic prophylaxis in radical retropubic prostatectomy and even in some clinical parameters piperacillin / tazobactam seems to be equivalent or better than the usual 5-day administration of antimicrobial prophylaxis.

We investigated the efficacy of prophylactic use of single dose oral ofloxacin and trimethoprim-sulfamethoxazole regimens for transrectal prostate biopsy in 110 men. In the ofloxacin, trimethoprim-sulfamethoxazole and control groups, urinary infection was found in 2 (4.76%), 3 (6.66%) and 6 (26.08%) patients, respectively. Both of these antibiotic regimens produced a statistically significant reduction in urinary infection (p<0.02, p<0.05). Our study indicates that single dose fluoroquinolone or trimethoprim-sulfamethoxazole prophylaxis seems to be effective, practical and economical.

Pneumocystis jirovecii, formerly known as Pneumocystis carinii, is an atypical fungal pathogen best known for causing Pneumocystis jirovecii pneumonia (PCP). The epidemiology of PCP is changing such that patients without HIV infection now comprise the largest subset of individuals diagnosed with PCP. While those with hematologic malignancies and organ transplants are at greatest risk for non-HIV-related PCP, this review will focus on PCP in patients with solid tumors. They are at risk for PCP due to their chemotherapy regimens and use of steroids in the management of various complications of treatment, and possibly because of the immunosuppressive effect of the cancer itself. In particular, patients with solid tumors being treated for metastatic spinal cord compression are at great risk for PCP. Patients with solid tumors and PCP face greater mortality than those with HIV infection. Multiple reviews have attempted to describe the ideal regimen of corticosteroids for metastatic spinal cord compression, but there is little consensus. We present 2 cases of patients with metastatic spinal cord compression due to prostate cancer undergoing radiation therapy and treatment with corticosteroids. These cases highlight the difficulties in predicting the length of corticosteroid therapy and the dangers that patients face without appropriate prophylaxis. This article will also provide a review of the current guidelines for PCP prophylaxis in patients undergoing treatment for metastatic spinal cord compression. We recommend empiric treatment with trimethoprim-sulfamethoxazole or dapsone in those patients with a sulfa allergy in all patients with solid tumors when any high-dose steroids are started for the treatment of metastatic spinal cord compression. Further research is needed to assess the epidemiology of PCP in patients with solid tumors and additional trials are necessary to refine PCP prophylaxis.

We present an isolate of Klebsiella pneumoniae OXA-48 isolated in a 68-year-old\ man who underwent radical prostatectomy due to prostate cancer. The antibiotic susceptibility testing\ to a wide range of antibiotics was performed by disk diffusion method and determination of minimal\ inhibitory concentrations. The isolate was classified as multidrug-resistant. It showed intermediate\ susceptibility to imipenem and meropenem, resistance to ertapenem, and sensitivity only to colistin,\ amikacin, and trimethoprim-sulfamethoxazole. The isolate was positive for ESBLs, negative for\ AmpC. Polymerase chain reaction and sequencing revealed bla(OXA-48)', bla(CTX-M-15) and bla(SHV-11). The plasmid\ encoding OXA-48 ß-lactamase did not belong to any known PCR-based replicon typing. According\ to genotyping, the isolate belonged to ST37.

Single institution and population-based studies highlight that infectious complications following transrectal ultrasound guided prostate needle biopsy (TRUS PNB) are increasing. Such infections are largely attributable to quinolone resistant microorganisms which colonize the rectal vault and are translocated into the bloodstream during the biopsy procedure. A povidone iodine rectal preparation (PIRP) at time of biopsy is a simple, reproducible method to reduce rectal microorganism colony counts and therefore resultant infections following TRUS PNB. All patients are administered three days of oral antibiotic therapy prior to biopsy. The PIRP technique involves initially positioning the patient in the standard manner for a TRUS PNB. Following digital rectal examination, 15 ml of a 10% solution of commercially available povidone iodine is mixed with 5 ml of 1% lidocaine jelly to create slurry. A 4 cmx4 cm sterile gauze is soaked in this slurry and then inserted into the rectal vault for 2 min after which it is removed. Thereafter, a disposable cotton gynecologic swab is used to paint both the perianal area and the rectal vault to a distance of 3 cm from the anus. The povidone iodine solution is then allowed to dry for 2-3 min prior to proceeding with standard transrectal ultrasonography and subsequent biopsy. This PIRP technique has been in practice at our institution since March of 2012 with an associated reduction of post-biopsy infections from 4.3% to 0.6% (p=0.02). The principal advantage of this prophylaxis regimen is its simplicity and reproducibility with use of an easily available, inexpensive agent to reduce infections. Furthermore, the technique avoids exposing patients to additional systemic antibiotics with potential further propagation of multi-drug resistant organisms. Usage of PIRP at TRUS PNB, however, is not applicable for patients with iodine or shellfish allergies.

• To review a contemporary cohort of patients undergoing a transrectal ultrasound-guided prostate needle biopsy (TRUS PNBx) at a single centre to determine the incidence of major complications necessitating hospital admission or emergency department (ED) visits.. • The charts of 1000 consecutive patients undergoing TRUS PNBx were reviewed. • All patients received peri-procedural antibiotic prophylaxis with either ciprofloxacin or co-trimoxazole. • Hospital admission and ED visits within 30 days of the procedure were identified for indication, management and outcome. • Patient comorbidities and biopsy characteristics were reviewed for association with complications.. • Of the 1000 patients, 25 (2.5%) had post-biopsy complications requiring hospital admission or an ED visit. • Indications included twelve patients (1.2%) with urosepsis, eight (0.8%) with acute urinary retention requiring urethral catheterization, four (0.4%) with gross haematuria requiring bladder irrigation for <24 h, and one (0.1%) with a transient ischaemia attack 1 day after biopsy. • Patients with urosepsis had an average hospitalization of 5 days, and 75% carried quinolone-resistant Escherichia coli organisms. • All patients with urinary retention had catheters removed within 10 days. No patients with haematuria required a blood transfusion. • No demographic or biopsy variables were particularly associated with development of a post-procedure complication.. • In this large contemporary series of TRUS PNBx, we observed a 2.5% rate of major complications requiring hospital admission or an ED visit. • No clinical or biopsy variables were directly associated with development of complications. • These data may be valuable when counselling patients before biopsy.

This study aimed to survey current Swedish practices for performing and handling transrectal ultrasound-guided prostate biopsies.. A Swedish Urology Network (SUNe) was organized for the distribution of information, survey studies and research collaborations. A web-based questionnaire was distributed to the members in 2011.. In this first SUNe survey, 137 (91%) of the 151 members replied. All used antibiotic prophylaxis (84% ciprofloxacin, 12% trimethoprim-sulfamethoxazole), most commonly (63%) as a single dose of ciprofloxacin. Local anaesthesia was used by 87%. Half of the respondents only used a "side-fire" probe, whereas 17% always used an "end-fire" probe. Most (84%) routinely took 10 or more biopsy cores. About three-quarters started with the right base of the prostate and did not routinely take midline biopsies. More than one-third never or rarely sampled the anterior part of the prostate. There was great variability in how biopsy location was reported, but 71% considered a national standardized coordinate system desirable. Fine-needle aspiration was used occasionally by 39%, in more than 10% of cases by 6% and always by 2%. Most urologists mounted the biopsy cores on paper before fixation (78%), put only one core per jar (75%) and used flat-bottomed jars (70%).. Most routines for handling of prostate biopsies, antibiotic prophylaxis, local anaesthesia and number of cores were uniform. However, there is still a need for standardization of the performance of ultrasound-guided biopsies. Although the method used to specify biopsy location varied greatly, most urologists would prefer a national standardized system.
