ESBL—Multi-Drug-Resistant UTI Creating Outpatient Treatment Challenge

Urinary tract infections (UTIs) are more common in female patients than males in all age groups. Some of the underlying risk factors increase the chances of UTI in male patients as well. Known risk factors like previous antibiotic use, catheterization history, nursing home residence, and previous hospitalizations are associated with drug-resistant UTIs, especially extended-spectrum beta-lactamase (ESBL). The presence of ESBL narrows down the treatment options. This case represents the patient with Klebsiella pneumoniae ESBL multidrug resistance (MDR) UTI, which was complicated by the history of previous pseudomonas UTI. The bacteria were sensitive only to injectable antibiotics, leaving no oral antibiotic options for treatment. This posed a significant challenge in managing the patient’s condition. UTI is the most commonly known cause of delirium and confusion in old age patients, so prompt treatment of UTI in these patients is paramount. This case highlights the need for further research to establish optimal antibiotic choices, particularly in the outpatient setting, for timely and adequate treatment of ESBL MDR UTI cases.
