Case series of emerging nosocomial multiple drug resistant pathogen providencia rettgeri causing urinary tract infection
Abstract
We report Case Series of Emerging Nosocomial Multiple Drug Resistant Pathogen Providencia rettgeri causing Urinary Tract Infections. The most common cause of catheter-associated urinary tract infections (CAUTI), especially with long-term indwelling urinary catheters in elders, are P. rettgeri and P. stuartii. We are reporting 4 cases of UTI, which are hospital-acquired and CAUTI. These cases are admitted to MICU for treatment purposes and later develop fever spikes after a few days and are evaluated and urine culture showed multi-drug-resistant Providencia rettgeri by VITEK. The empirical therapy was discontinued, managed with fosfomycin, and discharged later with follow-up. The various reports showed P. rettgeriis susceptible for amikacin, gentamicin, tobramycin and ciprofloxacin. In our case series, we isolated multi-drug-resistant strains of P. rettgeri that showed resistance to piperacillin-tazobactam, cefuroxime, ceftriaxone, cefepime, ertapenem, imipenem, meropenem, gentamicin, tobramycin, ciprofloxacin, tigecycline, amikacin, colistin and sensitive only to fosfomycin. The significance of P. rettgeri in association with catheter-related bloodstream infections (CRBSI) and catheter-associated urinary tract infections (CAUTI) was unclear. Hence isolation of Providencia species twice from the clinical samples was considered for association with catheter infections. The proper selection of empirical antimicrobials, antibiotic sensitivity testing, avoiding misuse of…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
