Emergence of as a Cause of Urinary Tract Infection: Results of the Routine Use of MALDI-TOF MS.

We analyzed the incidence and the clinical and laboratory characteristics of urinary tract infections (UTIs) during a 10-year period (2009-2018) and compared them with those of UTIs. A total of 38 and 162 episodes of and UTIs were observed. The number of UTIs was stable throughout the 10 years, whereas there was an obvious surge in the apparent number of UTIs since 2014, coinciding with the commencement of a routine use of MALDI-TOF MS. Univariate analysis showed that male sex ( < 0.001), advanced age ( < 0.001), hospital-acquired infections, ( < 0.001), upper UTI ( < 0.005), polymicrobial infections ( < 0.05), hypertension ( < 0.001), solid-organ malignancies ( < 0.001), renal stones ( < 0.001), urinary stricture ( < 0.05), vesicoureteral reflux ( < 0.001), and presence of a urinary catheter ( < 0.001) were significantly associated with UTI. Multivariable analysis revealed that UTI was associated with male sex (OR = 6.08, < 0.05), solid-organ malignancies (OR = 12.27, < 0.01), and urological system abnormalities (OR = 7.44, < 0.05). There were significant differences in the patient population affected and predisposing factors between and UTIs.
