A Systematic Review and Meta-Analysis of Methods Used to Reduce Infectious Complications Following Transrectal Prostate Biopsy

Reducing infectious complications and healthcare costs in transrectal ultrasound-guided prostate biopsy with single-dose cefmetazole and levofloxacin

INTRODUCTION

Fluoroquinolones (FQ) are currently the first choice as prophylactics for transrectal ultrasound-guided prostate biopsy (TRUS-PBx). However, infections caused by FQ-resistant or extended-spectrum β-lactamase producing Escherichia coli remain a significant concern. Although cefmetazole (CMZ) is effective against these resistant E. coli strains, there are only a few reports on its use in TRUS-PBx. We investigated the efficacy of antimicrobial prophylaxis (AP) for TRUS-PBx using intravenous CMZ and oral levofloxacin (LVFX).

METHODS

This single-center retrospective observational before-and-after study was conducted between January 2014 and December 2023 at Komaki City Hospital, Japan. The incidence of febrile urinary tract infection (UTI), urosepsis, bacteremia, readmission, abscess, and healthcare-related costs after TRUS-PBx were compared between individuals who received a single dose of intravenous cefazolin (CEZ) and oral LVFX and those who received single doses of intravenous CMZ and oral LVFX. The risk factors for post-TRUS-PBx febrile UTI were analyzed using multivariable logistic analysis.

RESULTS

The incidence of febrile UTI after TRUS-PBx was 0.77% (9/1,168) in the CEZ+LVFX group and 0.20% (2/1,008) in the CMZ+LVFX group. Complications such as urosepsis (5 cases), bacteremia (3 cases), abscess (2 cases), and readmission (3 cases) were observed only in the CEZ+LVFX group. Multivariable analysis indicated that the use of CMZ+LVFX significantly decreased febrile UTI after TRUS-PBx (odds ratio: 0.20, 95% confidence interval: 0.04-0.98, P = 0.047). CMZ+LVFX use reduced healthcare-related costs by JPY 975.5 (USD 6.8) per TRUS-PBx compared to CEZ+LVFX.

CONCLUSIONS

Empirical AP with CMZ+LVFX before TRUS-PBx reduced the incidence of infectious complications and healthcare-related costs.

Isepamicin alone as antimicrobial prophylaxis for transrectal prostate needle biopsy: "Do we still need levofloxacin? "

The purpose of this study was to investigate whether conventional levofloxacin (LVFX) administration is unnecessary for transrectal ultrasound-guided prostate needle biopsy (TRP-Bx) in view of the increase in LVFX-resistant Escherichia coli and appropriate use of antibiotics. The study included 636 cases undergoing TRP-Bx, divided into two groups based on the prophylactic antibiotic regimen. Group 1 (n = 308) received both oral levofloxacin (LVFX) 500 mg and intravenous isepamicin (ISP) 400 mg. Group 2 (n = 328) received only intravenous ISP 400 mg. Biopsies involved sampling 12 cores using an 18G needle. A high-risk subgroup included patients with a large prostate (>75 ml), severe dysuria, diabetes mellitus, or steroid use. Significantly more high-risk cases were in Group 2 than in Group 1 (35.7 % vs. 24.4 %, p = 0.003). Febrile genitourinary tract infections (fGUTIs) occurred in three patients (0.5 %), with no significant difference between the groups (0.3 % in Group 1 vs. 0.6 % in Group 2). No fGUTI complications were noted among high-risk cases in either group. Of the fGUTI cases, one involved LVFX-resistant E. coli; another involved E. coli susceptible to both LVFX and amikacin, isolated from blood. The single- and short-duration intravenous dose of ISP 400 mg would appear to be one of possible options in preventing TRP-Bx-related fGUTIs in both low-risk and high-risk patients.

French AFU Cancer Committee Guidelines - Update 2024-2026: Prostate cancer - Diagnosis and management of localised disease

OBJECTIVE

The aim of the Oncology Committee of the French Urology Association is to propose updated recommendations for the diagnosis and management of localized prostate cancer (PCa).

METHODS

A systematic review of the literature from 2022 to 2024 was conducted by the CCAFU on the elements of diagnosis and therapeutic management of localized PCa, evaluating references with their level of evidence.

RESULTS

The recommendations set out the genetics, epidemiology and diagnostic methods of PCa, as well as the concepts of screening and early detection. MRI, the reference imaging test for localized cancer, is recommended before prostate biopsies are performed. Molecular imaging is an option for disease staging. Performing biopsies via the transperineal route reduces the risk of infection. Active surveillance is the standard treatment for tumours with a low risk of progression. Therapeutic methods are described in detail, and recommended according to the clinical situation.

CONCLUSION

This update of French recommendations should help to improve the management of localized PCa.

A literature review of bioactive substances for the treatment of periodontitis: In vitro, in vivo and clinical studies

Periodontitis is a common chronic inflammatory disease of the supporting tissues of the tooth that involves a complex interaction of microorganisms and various cell lines around the infected site. To prevent and treat this disease, several options are available, such as scaling, root planning, antibiotic treatment, and dental surgeries, depending on the stage of the disease. However, these treatments can have various side effects, including additional inflammatory responses, chronic wounds, and the need for secondary surgery. Consequently, numerous studies have focused on developing new therapeutic agents for more effective periodontitis treatment. This review explores the latest trends in bioactive substances with therapeutic effects for periodontitis using various search engines. Therefore, this study aimed to suggest effective directions for therapeutic approaches. Additionally, we provide a summary of the current applications and underlying mechanisms of bioactive substances, which can serve as a reference for the development of periodontitis treatments.

Comparison of Fluoroquinolones and Other Antibiotic Prophylaxis Regimens for Preventing Complications in Patients Undergoing Transrectal Prostate Biopsy

Our study aimed to compare the incidence of infective complications after transrectal ultrasound-guided prostate biopsy (TRUSBx) when adopting different antimicrobial prophylaxis regimens. A multi-institutional cohort of 1150 patients who underwent TRUSBx was retrospectively analyzed. Procedures were performed between 2017 and 2019 (before and after the EMA warning about the use of fluoroquinolones for the antibiotic prophylaxis of patient candidates to TRUSBx). The primary endpoint was the occurrence of infective complications, including sepsis and/or fever. The population was stratified according to the antibiotic prophylaxis adopted: fluoroquinolones (levofloxacin, ciprofloxacin, prulifloxacin), cephalosporins (cefixime, ceftriaxone) or trimethoprim/sulfamethoxazole. Univariable and multivariable binomial logistic regression models were used to assess the odds ratio (OR) with 95% confidence interval (CI) testing of the risk of infective complication after adjusting for each prebiopsy covariate. In total, 478 (41.6%) patients received fluoroquinolone-based prophylaxis. Among these, 443 (38.5%), 25 (2.2%) and 10 (0.9%) patients received levofloxacin prophylaxis, ciprofloxacin and prulifloxacin, respectively while 14.6% received cefixime, 20.7% received the comedication of ceftriaxone/fosfomycin and 23.1% received trimethoprim/sulfamethoxazole. The trimethoprim/sulfamethoxazole and fluoroquinolone regimens were significantly associated with a lower risk of infective complications (OR 0.15, 95% CI 0.03−0.48, p = 0.003 and OR 0.17, 95% CI 0.06−0.43, p < 0.001, respectively). The ceftriaxone/fosfomycin (OR 0.21, 95% CI 0.04−0.92, p = 0.04) and fluoroquinolone (OR 0.07, 95% CI 0.00−0.70, p = 0.048) prophylaxis were associated with a lower risk of infective sequelae. Fluoroquinolone-based prophylaxis was associated with a lower risk of infective complications after TRUSBx compared to other prophylaxis regimens although its clinical application was recently forbidden by European Medical Agency restrictions.
