INTRODUCTION: Urinary tract infections (UTI) are the most frequent infection in kidney transplant (KT) patients. The main objective was to determine the clinical and microbiological characteristics of UTIs that occur during the first year after KT. METHODS: Retrospective cohort study that included patients over 18 years of age who received KT between 2009-2020 in two hospitals in Córdoba city, Argentina. Patients were followed up during the first year after the transplant by recording them in the medical records, and those who presented at least one episode of UTI were analyzed...

Urinary tract infections (UTIs) are a common health concern. Urine culture is the "gold standard" for UTI diagnosis but takes 48h. Rapid methods like dipstick tests are used as point-of-care tests. However, their sensitivity and specificity are variable. In this work, a rapid immunochromatographic test (IT) for detecting Escherichia coli in urine was developed, and its performance was evaluated in urine samples from patients with suspected UTI. The "universal lateral flow assay kit" was employed using an E...

Uncomplicated urinary tract infection (UTI) is the most common bacterial infection in women. Since 1948, the relationship between urinary pH and antibiotics (ABs) has been established. We aimed to search for the best urinary pH for each family of antibiotics and to assess whether pH changes bacterial susceptibility to them. We included in vitro research and in vivo studies including one or more bacterial species and tested the effect of one or more ABs at different pH values. We also included randomized controlled clinical trials (RCTs) in uncomplicated UTI (EAU guidelines 2019 definition), choosing the ABs based on urinary pH or using an antibiotic plus urinary pH modifiers (L-methionine, vitamin C…) vs...

PubMed was searched for paired sample studies and controlled trials. Studies comparing UCDs with non-invasive urine collection procedures were considered. RESULTS: Only two studies were found...

In 2015, the "New recommendations regarding the current controversies in urinary infection" were published in the Archivos Argentinos de Pediatría. Given the fact that in these past years, new evidence has emerged regarding the diagnosis and treatment of urinary infection, the Pediatric Nephrology Committee of Sociedad Argentina de Pediatría has decided to update these recommendations. The main goal is to provide the pediatrician with the necessary tools to make a correct diagnosis, define the most appropriate treatment, select the patients who will benefit from antibiotic prophylaxis, and decide which imaging studies will be necessary, avoiding costly and invasive interventions...
