cefoxitin and Prostatitis

The emergence of extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) infections requires re-assessment of therapeutic choices. Here we report the efficacy of cefoxitin-based antibiotic therapy for ESBL-E prostatitis. A prospective study including patients with ESBL-E prostatitis resistant to trimethoprim/sulfamethoxazole and fluoroquinolones from January 2014 to March 2016 was conducted. Cefoxitin was administered by continuous infusion for 3 weeks in the case of acute bacterial prostatitis or 6 weeks in the case of chronic bacterial prostatitis (CBP), with intravenous fosfomycin for the first 5 days. Urological investigations were performed to diagnose underlying urinary tract pathology. Clinical and microbiological efficacy were evaluated 3 months (M3) and 6 months (M6) after the end of therapy. A total of 23 patients were included in the study. The median patient age was 74 years (range 48-88 years). Of the 23 infections, 14 (61%) were CBP and 12 (52%) were healthcare-associated infections. The bacteria involved were Escherichia coli in 11 cases, Klebsiella pneumoniae in 10 cases and Klebsiella oxytoca in 2 cases. Clinical cure was observed in 19/23 patients (83%) at M3 and in 17/22 patients (77%) at M6. Urocultures were sterile in 13/23 patients (57%) at M3 and in 9/19 patients (47%) and M6. Urinary colonisation was observed in 6/19 patients (32%) with clinical cure at M3 and 5/14 patients (36%) with clinical cure at M6. No resistance to cefoxitin was detected. Surgical treatment was required for 7/23 patients (30%). In conclusion, cefoxitin-based antibiotic therapy is suitable for difficult-to-treat ESBL-E infections such as prostatitis.

To analyze whether strains positive for extended-spectrum β-lactamase (ESBL) affected the clinical course and progression to chronic prostatitis in patients with postbiopsy acute prostatitis.. From 2002 to 2011, 3657 patients underwent transrectal ultrasound-guided biopsy of the prostate, and 33 patients with acute prostatitis were enrolled. Acute prostatitis was defined as a fever greater than 38°C, pyuria, and tenderness on digital rectal examination. Urine and blood cultures were tested for antibiotic susceptibility. Laboratory and clinical variables according to the presence of ESBL were analyzed.. Blood or urine culture was positive in 23 patients. The most common strain was Escherichia coli. Sixteen patients showed ESBL-positive and 18 patients were quinolone-resistant. Thirteen of 16 patients with ESBL-positive strains showed quinolone resistance, and 13 of 18 patients with quinolone resistance were ESBL-positive (P = .621). Besides imipenem, all ESBL-positive patients were susceptible to amikacin and were highly susceptible to cefoxitin and amoxicillin/clavulanic acid. The prevalence of ESBL-positive strains has tended to increase since 2006. Patients with ESBL had higher peak fever, white blood cell count, absolute neutrophil count, and longer duration of fever and hospitalization. The progression rate to chronic prostatitis was significantly higher in ESBL-positive patients (4/16 vs 0/17, P = .044).. Since 2006, ESBL strains have been increasing, and the presence of ESBL showed more detrimental effects on the clinical course of the patients, resulting in a higher rate of progression to chronic prostatitis.

Complicated infections caused by penicillinase-producing Neisseria gonorrhoeae (PPNG) are uncommon. Of two patients with prostatitis due to PPNG, one was cured by cefoxitin followed by co-trimoxazole, the other by co-trimoxazole alone. The potential of co-trimoxazole in the treatment of PPNG-prostatitis looks promising.
