Urinary tract infections to Enterococcus spp.: Risk factors and treatments

Non complicated acute urinary tract infections (UTI) are among the most common bacterial diseases in the human species. More than 150 million UTIs (non complicated/complicated) are, in fact, annually diagnosed and treated worlwide (Sobel Kaye, 1990; Stamm and Hooton, 1993; Stamm, 1998; Stamm and Norrby, 2001; Foxman, 2002). UTI include cystitis and pyelonephritis (the latter is not discussed in this paper) that occur in individuals without morphological-functional alterations of the excretory tract. This disease is more common in female and/or in menopause patients. 25-50% of the individuals in this population, aged between 20 and 40 years, can be affected by UTI at least once in a lifetime and can be prone to more or less frequent relapses. (Johnson, 1998; Stamm, 2001). Male subjects are less frequently affected by UTI, but when affected, they experience more serious episodes often representing a warning signal of anatomical alterations of the urinary apparatus or the presence of risk factors.......

Tract Infections

Introduction: Urinary tract infection is the most common infectious complication following renal transplantation and its frequency is insufficiently studied in Portugal. The aim of this study was to characterize the incidence of urinary tract infections and recurrent urinary tract infections in renal transplant recipients. Material and Methods: This was a retrospective cohort observational study, obtained from clinical files of all patients who received a renal transplant at the Hospital of Santa Cruz, from January 2004 to December 2005, with a mean follow-up period of five years or until date of graft loss, death or loss of follow-up. After a descriptive analysis of the population, we used bivariate tests to identify risk factors for urinary tract infections. Results: A total of 127 patients were included, with a 593 patients.year follow-up. We detected 53 patients (41.7%) presenting with at least one episode of urinary tract infection; 21 patients (16.5%) had recurrent urinary tract infection. Female gender was the only risk factor associated with the occurrence of urinary tract infections (p < 0.001, OR = 7.08, RR = 2.95) and recurrent urinary tract infections (p < 0.001, OR = 4.66, RR = 2.83). Escherichia coli (51.6%), Klebsiella pneumoniae (15.5%) and Enterobacter spp (9.9%) were the most frequently identified pathogens. Patients did not reveal an increased mortality or allograft loss. However, urinary tract infections were the most important cause of hospital admissions. Discussion: Female gender was the only risk factor for urinary tract infections in this population. Escherichia coli was the most frequent agent isolated. Conclusion: Despite preventive measures, urinary tract infections remain an important cause of morbidity and hospital admissions.

Microbiological Cure

Background: Bacterial resistance among uropathogens is on the rise and has led to a decreased effectiveness of oral therapies. Fosfomycin tromethamine (fosfomycin) is indicated for uncomplicated urinary tract infections (UTIs) and displays in vitro activity against multidrug-resistant (MDR) isolates; however, clinical data assessing fosfomycin for the treatment of complicated or MDR UTIs are limited. Methods: We conducted a retrospective evaluation of patients who received ≥1 dose of fosfomycin between January 2009 and September 2015 for treatment of a UTI. Patients were included if they had a positive urine culture and documented signs/symptoms of a UTI. Results: Fifty-seven patients were included; 44 (77.2%) had complicated UTIs, 36 (63.2%) had MDR UTIs, and a total of 23 (40.4%) patients had a UTI that was both complicated and MDR. The majority of patients were female (66.7%) and elderly (median age, 79 years). Overall, the most common pathogens isolated were Escherichia coli (n = 28), Enterococcus spp. (n = 22), and Pseudomonas aeruginosa (n = 8). Twenty-eight patients (49.1%) were clinically evaluable; the preponderance achieved clinical success (96.4%). Fifteen out of 20 (75%) patients with repeat urine cultures had a microbiological cure. Conclusions: This retrospective study adds to the limited literature exploring alternative therapies for complicated and MDR UTIs with results providing additional evidence that fosfomycin may be an effective oral option.
