A single dose of ciprofloxacin reduces the duration of diarrhea among service members deployed in Africa. Infect Dis Now 2023; 53:104643. [PMID: 36642099 DOI: 10.1016/j.idnow.2023.01.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 12/27/2022] [Accepted: 01/06/2023] [Indexed: 01/15/2023]
Abstract
OBJECTIVES To assess the effectiveness of the adjunction of a one-gram single dose of ciprofloxacin to a symptomatic treatment for the early treatment of uncomplicated diarrhea during military operations of the French service members in Africa. PATIENTS AND METHODS This phase IV, multicentric, randomized, open-label, controlled trial was conducted in Chad, Mali, and in Central African Republic. A total of 267 French service members having at least one loose stool in the previous 24 hours were enrolled from May 2015 to June 2016. Participants were randomized to receive ciprofloxacin 1 g and a symptomatic treatment (racecadotril 100 mg three times a day and ad libidum oral rehydration solution) or a symptomatic treatment alone. The primary outcome was the duration of the diarrhea. Secondary outcomes were evaluated at the 72-hour endpoint and included recovery status, number of loose stools, frequency and duration of associated symptoms and safety of treatments. RESULTS Among 267 participants, 242 completed the trial. Participants receiving ciprofloxacin and a symptomatic treatment (n = 124) were significantly more likely to be cured at the endpoint than those who only received a symptomatic treatment (118): 94.4 % versus 74.6 % (OR = 5.7; 95 %CI: [2.4-13.6]; p < 10-3). The antibiotic therapy reduced the average diarrhea duration by 30 % (p = 10-4). Fever at inclusion was associated with a longer episode (HR = 0.61; 95 %CI: [0.41-0.89]; p = 0.012). No adverse event of medications was reported. CONCLUSION A single dose of ciprofloxacin was effective and safe in treating uncomplicated diarrhea among service members in Africa.

Baldissera-Aradas J, Rodríguez-Villamil L, Blanco-Fernández R, Pérez-García C, Viejo de la guerra G, González-Rodríguez I, Mosquera-Madera J. Rectal culture-directed antibiotic prophylaxis before transrectal prostate biopsy: Reduced infectious complications and healthcare costs. Actas Urol Esp 2018; 42:465-472. [PMID: 29331324 DOI: 10.1016/j.acuro.2017.10.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2017] [Revised: 09/29/2017] [Accepted: 10/31/2017] [Indexed: 10/18/2022]
Abstract
BACKGROUND Transrectal ultrasound-guided prostate biopsy (TUPB) is associated with infectious complications (ICs), which are related to a greater prevalence of ciprofloxacin-resistant bacteria (CRB) in rectal flora. We examined the ICs that occurred in 2 groups: A guided antibiotic prophylaxis (GP) group and an empiric prophylaxis (EP) group. We assessed the financial impact of GP. MATERIAL AND METHODS The GP group was studied prospectively (June 2013 to July 2014). We collected rectal cultures (RCs) before the TUPB, which were seeded on selective media with ciprofloxacin to determine the presence of CRB. The patients with sensitive bacteria were administered ciprofloxacin. Patients with resistant bacteria were administered GP according to the RC antibiogram. The EP group was studied retrospectively (January 2011 to June 2009). RCs were not performed, and all patients were treated with ciprofloxacin as prophylaxis. The ICs in both groups were recorded during a period no longer than 30 days following TUPB (electronic medical history). RESULTS Three hundred patients underwent TUPB, 145 underwent GP, and 155 underwent EP. In the GP group, 23 patients (15.86%) presented CRB in the RCs. Only one patient (0.7%) experienced a UTI. In the EP group, 26 patients (16.8%) experienced multiple ICs (including 2 cases of sepsis) (P<.005). The estimated total cost, including the management of the ICs, was €57,076 with EP versus €4802.33 with GP. The average cost per patient with EP was €368.23 versus €33.11 with GP. GP achieved an estimated total savings of €52,273.67. Six patients had to undergo GP to prevent an IC. CONCLUSIONS GP is associated with a marked decrease in the incidence of ICs caused by CRB and reduced healthcare costs.

Abstract
PURPOSE To compare the efficacy of three chemoprophylaxis approaches in prevention of post-transrectal biopsy infectious complications (TBICs). METHODS Patients were randomly assigned to receive ciprofloxacin 3 days 500 mg B.I.D 3 days starting the night prior to biopsy (standard prophylaxis), augmented prophylaxis using ciprofloxacin and single preprocedure shot of 160 mg gentamicin IM (augmented prophylaxis) and rectal swab culture-based prophylaxis (targeted prophylaxis). Patients were assessed 2 weeks prior to biopsy, at biopsy and 2 weeks after. Primary end point was occurrence of post-TBICs that included simple UTI, febrile UTI or sepsis. Secondary end points were post-biopsy change in the inflammatory markers (TLC, ESR and CRP), unplanned visits, hospitalization and occurrence of fluoroquinolones resistance (FQ-R; bacterial growth on MacConkey agar plate with 10 μg/ml ciprofloxacin) in the fecal carriage of screened men. RESULTS Between April/2015 and January/2017, standard, augmented and targeted prophylaxes were given to 163, 166 and 167 patients, respectively. Post-TBICs were reported in 43 (26%), 13 (7.8%) and 34 (20.3%) patients following standard, augmented and targeted prophylaxes protocols, respectively (P = 0.000). Post-TBICs included UTI in 23 (4.6%), febrile UTI in 41 (8.2%) and sepsis in 26 (5.2%) patients. Significantly lower number of post-biopsy positive urine culture was depicted in the augmented group (P = 0.000). The number of biopsy cores was statistically different in the three groups (P = 0.004). On multivariate analysis, augmented prophylaxis had independently lower post-TBICs (OR 0.2, 95% CI 0.1-0.4, P = 0.000) when compared with the other two groups regardless of the number of biopsy cores taken (OR 1.07, 95% CI 0.95-1.17, P = 0.229). Post-biopsy hospitalization was needed in four (2%), one (0.6%) and ten (6%) patients following standard, augmented and targeted prophylaxes, respectively (P = 0.014). However, sepsis-related hospitalization was not statistically different. Post-biopsy changes in the inflammatory markers were significantly less in augmented prophylaxis (P < 0.05). FQ-R was depicted in 139 (83.2%) of the screened men. CONCLUSION Augmented prophylaxis with single-dose gentamicin is an effective and practical approach. Targeted prophylaxis might be reserved for cases with contraindication to gentamicin.

Prevalence of fluoroquinolone-resistant rectal flora in patients undergoing transrectal ultrasound-guided prostate needle biopsy: A prospective multicenter study. Int J Urol 2017; 25:278-283.

Abstract
OBJECTIVES To estimate the prevalence of fluoroquinolone-resistant rectal flora in patients undergoing transrectal ultrasound-guided prostate needle biopsy and to identify the high-risk groups. METHODS From January 2015 to March 2016, rectal swabs of 557 men who underwent transrectal ultrasound-guided prostate needle biopsy were obtained from five institutions. Clinical variables, including demographics, rectal swab culture results and infectious complications, were evaluated. Univariable and multivariable analyses were used to identify the risk factors for fluoroquinolone resistance of rectal flora and infectious complications. RESULTS The incidence of fluoroquinolone-resistant and extended-spectrum beta-lactamase production was 48.1 and 11.8%, respectively. The most common fluoroquinolone-resistant bacteria was Escherichia coli (81% of total fluoroquinolone-resistant bacteria, 39% of total rectal flora), and 16 (2.9%) patients had infectious complications. Univariable and multivariable analysis of clinical parameters affecting fluoroquinolone resistance showed no factor associated with fluoroquinolone resistance of rectal flora. The clinical parameter related to infectious complications after prostate biopsy was a history of operation within 6 months (relative risk 6.60; 95% confidence interval 1.99-21.8, P = 0.002). CONCLUSIONS These findings suggest that a risk-based approach by history taking cannot predict antibiotic resistance of rectal flora, and physicians should consider targeted antibiotic prophylaxis or extended antibiotic prophylaxis for Korean patients undergoing transrectal ultrasound-guided prostate biopsy because of high antibiotic resistance of rectal flora.

Abstract
BACKGROUND We evaluated the effectiveness of targeted antimicrobial prophylaxis in transrectal ultrasound guided prostate biopsy (TRUSP). METHODS A prospective, non-randomized cohort study was conducted. Rectal swab cultures plated on non-selective blood agar and on selective MacConkey agar supplemented with ciprofloxacin identified ciprofloxacin-susceptible and -resistant gram-negative bacteria (CS-GNB and CR-GNB). Patients with CS-GNB received ciprofloxacin while those with CR-GNB received directed prophylaxis. Infectious complications were defined clinically and microbiologically within 30 days after TRUSP. Data were derived at 7 and 30 days post procedure by questionnaires and electronic medical records. We hypothesized that there would be no difference in the infectious outcomes among the CS and CR groups. RESULTS From November 1, 2012 to March 31, 2015, 510 men completed the study; 430 (84.3%) had CS-GNB and 80 (15.7%) had CR-GNB. 484 (94.9%) completed the study per protocol, while 26 (5.1%) had an intention-to-treat (ITT) analysis. Of the 484, 475 (98.1%) had no infections, nine (1.9%) had infections, six of which (1.2%) were culture-proven (CP). The nine infections were as follows: five (1.0%) uncomplicated UTIs, one (0.2%) complicated UTI, and three (0.6%) urosepsis. One case of uncomplicated UTI and two cases of urosepsis were not CP, but were diagnosed clinically. ITT outcomes were similar. The infection rates were not statistically different between the CS-and CR-GNB patients (p-value = 0.314; 95% CI 0.8-3.3). The four patients with complicated UTIs or sepsis were hospitalized for a mean of 2.6 days and discharged without sequelae. Of the nine infections, three were antimicrobial prophylaxis failures (two ciprofloxacin and one amikacin); three were likely due to failure of the collection or processing of the rectal swab or increasing bacterial resistance between the time of swab collection and biopsy, and three developed clinical infections with no isolate recovered. CONCLUSIONS Targeted antimicrobial prophylaxis follows the principles of antimicrobial stewardship and achieved a low rate of infectious complications with limited morbidity and no sequelae. This individualized method of prophylaxis may be widely applied. Further studies are needed to explore reasons for targeted prophylaxis failure and to determine comparative efficacy of non-ciprofloxacin-containing targeted prophylaxis regimens. TRIAL REGISTRATION ClinicalTrials.gov. NCT01659866 . Registered 9 July 2012. First patient enrolled 1 November 2012.

Abstract
Although febrile complications are rarely encountered after a prostate biopsy procedure, in recent years the number of cases of fatal infection after that have increased along with increases in resistant bacteria. The available biopsy approaches are transrectal and transperineal, with the transrectal approach primarily used. As the invasion path of the puncture needle differs between these approaches, pretreatment and the method of administration of preventive antimicrobial drugs should be separately considered for infection prevention. Recently, the Japanese guidelines for perioperative infection prevention in the field of urology were revised after receiving approval from the Japanese Urological Association. With use of the transrectal approach, attempts have been made to selectively administer prophylactic antibiotics by confirming the presence or absence of resistant bacteria in rectal swab culture results before carrying out a prostate biopsy procedure because of potential problems associated with resistant bacteria in rectal flora. For preventive antibiotics, a single dose of oral quinolone is recommended for patients with low risk, whereas daily administrations of piperacillin/tazobactam are recommended for those considered to be high risk. In contrast, for the transperineal procedure, a single dose of oral quinolone is recommended as a preventive antibiotic. With both approaches, it is important to empirically administer broad-spectrum antimicrobials when occurrence of a febrile infection after a prostate biopsy procedure is confirmed.

Abstract
A systematic review to identify risk factors for prostate biopsy-related infection, preventative strategies, and optimal management of infectious complications was conducted. Significant risk factors for postbiopsy infection include urogenital infection, antibiotic use, international travel, hospital exposure, bacteriuria, previous transrectal biopsy, and resistance of fecal flora to antibiotic prophylaxis (especially fluoroquinolones). Patients at risk may benefit from an adjusted biopsy protocol comprising transrectal biopsy under targeted prophylaxis, and/or the use of rectal disinfection techniques or using a transperineal approach. Management of biopsy-related infection should be based on individual risk and local resistance profiles with input from multiple specialties.

Abstract
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.

Abstract
BACKGROUND Fluoroquinolone (FR) resistant Escherichia coli infection has become a global problem. The FR resistance usually occurs mainly due to specific point of mutations within the quinolone resistance-determining regions (QRDRs) at the gyrA codon of Ser83 and Asp87 and the parC codon of Ser80 and Glu84. Here, we appraised type and frequency of the QRDR mutations in FR-resistant E. coli isolates, and developed multiplex allele specific PCR (MAS-PCR) for the detection of "hot spot" mutations. METHODS A total of 111 ciprofloxacin-resistant E. coli from Ramathibodi Hospital in Bangkok, Thailand, were performed Minimum Inhibitory Concentration (MIC) by Etest® and investigated for gyrA and parC genes' mutations by MAS-PCR. Sensitivity and specificity of MAS-PCR were compared to the sequencing method's. RESULTS Ninety-nine of 111 (89.19%) E. coli isolates had mutation at least one point in the QRDRs. Six usual amino acid substitutes were reported, including Ser83-Lue, Asp87-Asn, Asp87-Tyr, Ser80-Ile, Glu84-Gly, and Glu84-Val. MAS-PCR detected codons 83 and 87 in gyrA and codons 80 and 84 in parC mutations, yielding 96.97%, 100%, 100%, and 93.33% sensitivity, respectively, and 100%, 100%, 100%, and 98.48% specificity, respectively. CONCLUSION MAS-PCR may be used for rapid detection of FR resistance in routine laboratory as well as in epidemiology study.

Prevalence, Risk Factors, and Clinical Relevance of Fluoroquinolone-Resistant Organisms in Rectal Cultures: Should We Target Antibiotic Prophylaxis Prior to Prostate Biopsy? Adv Urol 2016; 2016:5392107. [PMID: 27034660 PMCID: PMC4791502 DOI: 10.1155/2016/5392107] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2015] [Accepted: 02/09/2016] [Indexed: 11/17/2022] Open
Abstract
The rise of infectious complications after prostate biopsy has been linked to the growing resistance of enterobacteria to fluoroquinolone (FQ) antibiotics. In this review, we investigated the potential benefit of targeted antibiotic prophylaxis based on rectal cultures prior to prostate biopsy. An electronic search for all related literature published in English was performed from April until June 2015 using the MEDLINE and EMBASE databases. Data were obtained regarding the true prevalence of FQ-resistant bacteria in the rectum of patients, the identification of those patients at risk of harbouring FQ-resistant bacteria, the risk of infectious complications after transrectal prostate biopsy in patients with FQ-resistant bacteria, and the effect of targeted prophylaxis. Although there is limited evidence that a targeted approach might be beneficial, we conclude that current studies on the use of rectal cultures in the prebiopsy setting have too many limitations and confounding variables to definitely accept this approach in clinical practice. Whether this methodology is useful in a certain region will greatly depend on local fluoroquinolone-resistance rates.

Abstract
Cancer is a major health burden among non-communicable diseases, which has had a high impact on the healthcare system in Thailand. Based on GLOBOCAN, the prevalence of urologic cancer is increasing in Thailand. Prostate, bladder and kidney cancers are 6th, 15th and 22nd most common cancers, respectively, in both males and females. Prostate cancer is the fourth most common cancer in male. Cancer in the lower socioeconomic groups is a challenging problem due to greater exposure to the risk factors and more limited access to the healthcare service. The cancers are usually detected in advanced stages of the cancer. The most common histopathological finding of kidney cancer is a renal cell carcinoma. Transitional cell carcinoma is the most common histopathology of bladder. There is a trend of stage migration to earlier stages at first presentation, probably due to public awareness and laboratory screening. Patients with early stage are treated with minimally invasive modalities such as endoscopic, laparoscopic or robot-assisted laparoscopic surgery. Laparoscopic radical prostatectomy and robot-assisted laparoscopic radical prostatectomy is the mainstay treatment of localized prostate cancer with the better outcome and less complication. Androgen deprivation therapy is usually for elderly or unfit patients. The strategy for early detection of early cancer is the important role of Thai urologists to manage these three common urologic cancers.

Abstract
BACKGROUND Despite frequent use of prophylactic antibiotics for patients undergoing transrectal prostate biopsy (TRPB), the incidences of urinary tract infection (UTI) and bacteria resistance are increasing. The aim of this study is to evaluate the current regimen of antimicrobial prophylaxis in TRPB. METHODS A systematic search of PubMed(®), Embase(®), and the Cochrane Library was performed to identify all randomized controlled trials (RCT) related to the effects of antibiotic prophylaxis for TRPB. The outcomes included bacteriuria, bacteremia, drug-resistant bacteria on urine/blood culture, fever, UTI, sepsis, and hospitalization. RESULTS A total of 22 RCTs with 3846 patients were identified and included. Nine trials analyzed antibiotics versus placebo/no treatment, with all outcomes substantially favoring antibiotic use (p<0.05), including bacteriuria (risk ratio [RR] 0.25, 95% confidence interval [CI] 0.15-0.42), bacteremia (RR 0.67, 95% CI 0.49-0.92), fever (RR 0.39, 95% CI 0.23-0.64), UTI (RR 0.37, 95% CI 0.22-0.62), and hospitalization (RR 0.13, 95% CI 0.03-0.55). There were no substantial differences between long-course versus short-course treatment and single versus multiple dose respectively, except for a greater risk of bacteriuria for short-course treatment (RR 2.09, 95% CI 1.17-3.73, p=0.01) and single-dose treatment (RR 1.98, 95% CI 1.18-3.33, p=0.01). There were no substantial differences among the groups for bacteriuria, fever, UTI, and hospitalization, when comparing oral versus systemic administration of antibiotics. The efficacy of several classes of antibiotics was compared without any difference among them. Despite the lack of significance, the synthesized data of three RCTs indicated a trend towards the use of combined antibiotics. CONCLUSIONS Prophylactic antibiotics could be beneficial for the reduction of infective complications after TRPB. Single-dose or short-course oral administration with any type of antibiotic appears to be optimal. One additional type of antibiotic added to the basic antibiotic agent may contribute to the minimization of severe infection and drug resistance.

Abstract
OBJECTIVE Prostate biopsy is the standardized diagnostic method for prostate cancer. However, although there is not a standardized protocol, there are recommendations in order to reduce the incidence of complications. The objective of the present work is to assess the efficacy and safety of antibiotic prophylaxis in the prostate biopsy by comparing two antibiotic regimes: two doses of fosfomycin-trometamol 3g (FMT) every 48 hours with 10 doses of oral ciprofloxacin 500 mg every 12 hours during 5 days. MATERIAL AND METHODS Randomized prospective study was performed with 671 patients who had undergone to walking transrectal ultrasound guided prostate biopsy. Patients of group A (n=312) were treated with ciprofloxacin, and patients of group B (n=359) with FMT. Efficacy and tolerability of two prophylactic regimes were compared. Urine culture was carried out at 2 weeks after biopsy. Initially, patients with asymptomatic bacteriuria were not treated with antibiotics; urine culture was repeated after 1 month, persistent bacteriuria was treated according to antibiogram. RESULTS No differences between groups were found in age (P=.78), cancer presence (P=.9) or number of biopsy cylinders (P=.93). The mean number of cores obtained was 11.3 ± 3.25 (range 6-20). Digestive intolerance was observed for 9 patients (2.9%) of group A and 10 patients (2.8%) in group B. One patient (.3%) of group A showed severe allergic reaction. In total, 167 patients (24.6%) had complications: 16 (2.4%) fever, 47 (6.9%) hemospermia, 81 (11.9%) hematuria, 7 (1%) rectal bleeding and 16 (2.4%) urinary retention. No statistically differences between groups were observed (27.6% vs. 22.6%; P=.17). However, hemospermia was more frequent in group A (9.9% vs. 4.5%; P=.006). Bacteriuria after biopsy was detected in 44 patients (6.6%), being more frequent in group B patients (4.2% vs. 8.6%; P=.02) although a higher number of second treatment cycles were not needed (53.9% vs. 29%; P=.17). The likelihood of resistance to ciprofloxacin in patients with bacteriuria in A was greater than that of FMT in B (69.2% vs. 41.9%; P=.0004). CONCLUSIONS Antibiotic prophylaxis with FMT (2 doses of 3g) in prostate biopsy is an alternative as effective and safe as ciprofloxacin (10 doses of 500 mg), which carries lower rate of resistance. According to our experience, this drug is a safe, well-tolerated, and easily manageable prophylactic option, facilitating patient compliance. More prospective multicenter studies are necessary to confirm these findings.

Use of outpatient parenteral antimicrobial therapy for transrectal ultrasound-guided prostate biopsy prophylaxis in the setting of community-associated multidrug-resistant Escherichia coli rectal colonization. Urology 2014; 83:710-3. [PMID: 24680441 DOI: 10.1016/j.urology.2013.12.039] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2013] [Revised: 12/19/2013] [Accepted: 12/20/2013] [Indexed: 11/30/2022]
Abstract
OBJECTIVE To study the use of ertapenem delivered in an outpatient parenteral antimicrobial therapy (OPAT) hospital-based unit setting for targeted transrectal ultrasound-guided prostate biopsy (TRUSPBx) prophylaxis in the setting of multidrug-resistant (MDR) Escherichia coli rectal colonization. E coli is the pathogen most commonly associated with post-TRUSPBx complications, and there is increasing prevalence of community-associated MDR E coli. METHODS Prospective data analysis of all patients admitted to the OPAT unit for administration of intravenous antibiotics for prophylaxis for TRUSPBx over 18-month period was performed. Patients had identification of MDR E coli in rectal swab cultures and/or intolerance to available oral agents. Microbiologic data and tolerability of administered antibiotics and outcome after TRUSPBx were tabulated. RESULTS Nine patients (median age 74 years) were referred because of antibiotic-resistant E coli from rectal swabs (all fluoroquinolone resistant, 7 MDR). All patients received ertapenem 1 g intravenously 1 day before TRUSPBx and the day of the procedure before TRUSPBx. None of the patients experienced infectious complications immediately after TRUSPBx or several weeks or months later, and no patient was lost to urologic follow-up. CONCLUSION Increasing worldwide reports of prostatitis, urinary tract infections, and septicemia after TRUSPBx because of MDR E coli suggest rectal screening before procedure may be useful in decreasing complications. Targeted prophylaxis in these instances is necessary. Although carbapenems are used for treatment, they are not routinely used for prophylaxis. We report successful use of ertapenem delivered in a hospital-based OPAT unit for TRUSPBx prophylaxis.

Abstract
Purpose The prevalence of antibiotic-resistant bacteria on rectal swabs in patients undergoing transrectal ultrasound (TRUS)-guided prostate biopsy and the factors affecting resistance to antibiotics were evaluated. Materials and Methods Two hundred twenty-three men who underwent TRUS-guided prostate biopsy from November 2011 to December 2012 were retrospectively evaluated. Rectal swabs were cultured on MacConkey agar to identify antibiotic-resistant bacteria in rectal flora before TRUS-guided prostate biopsy. All patients were admitted and received intravenous antibiotics before prostate biopsy. Clinical variables including underlying disease, infectious complications, and antibiotics associated with resistance were evaluated. Logistic regression was used to determine the factors influencing antibiotic resistance. Results Of the 233 patients, 161 had positive rectal cultures. Escherichia coli was cultured in 130 (80.7%) and Klebsiella pneumonia in 16 (9.9%). The prevalence of quinolone resistance was 16.8% and the prevalence of extended-spectrum beta-lactamase (ESBL) positivity was 9.3%. A previous history of prostatitis was correlated with quinolone resistance and ESBL positivity (both p=0.001). The factors affecting quinolone resistance in the univariate analysis were a previous history of prostatitis (p=0.003) and previous exposure to antibiotics (p=0.040). Only a previous history of prostatitis was statistically significant in the multivariate analysis (p=0.014). Four patients had infectious complications. Conclusions The prevalence of quinolone resistance was 16.8% in rectal swabs performed before TRUS-guided prostate biopsy. A previous history of prostatitis was influential. In patients with a history of prostatitis, selection of prophylactic antibiotics before the biopsy may be reconsidered.
