Bacterial Metallophores in the Diagnosis of Acute Pyelonephritis
Acute PyelonephritisComplicated Urinary Tract InfectionThe project aims to investigate bacterial metallophores as potential diagnostic markers of acute pyelonephritis and complicated urinary tract infections. These secondary metabolites are excreted by pathogenic microorganims in the course of infection for the uptake of iron and other metallic ions from the host. They are species-specific and can be detected in body fluids (including urine) by mass spectrometry. The potential contribution of this project is a culture-independent method for the diagnosis of the causative microbiological agent.
The Microbiota in Kidney Donation and Transplantation
Kidney DiseasesKidney Transplant Failure and Rejection1 moreThe human gastrointestinal tract harbours ~40 trillion microbial cells, far outnumbering the cell number, and therefore the genetic content of its host. How this genetically diverse bacterial (collectively referred as 'microbiota') co-resident modulates host homeostasis is largely unknown. We are increasing gaining a better understanding how the microbes modulate mucosal and systemic metabolic/immune and organ systems including the kidney, heart and the brain. Therapeutic targeting of the gastrointestinal (GI) microbiota may help improve clinical outcomes in conditions as diverse as arthritis, cardiovascular disease, and cancer. In contrast to other organ systems, studies investigating the role of the microbiota in modulating clinical outcomes in renal transplantation lags behind. The aim of the study is to examine (a) how alterations in the urinary and GI microbiota and associated metabolites impact on host immunity after renal transplantation, and (b) whether such changes are correlated with post-transplant complications, such as rejection, development of de novo donor specific antibodies, metabolic complications (e.g post-transplant diabetes) and infections. Participants will be followed before and up to twelve months post-transplantation, and, longitudinal microbial data will be correlated with in-depth immune phenotyping and clinical end-points to define the impact that changes in urinary and GI microbial ecology have on kidney transplant outcomes.
Infectious Complications After Cystectomy: A Prospective Observational Study
Bladder CancerInfections8 moreIn this study, we evaluate peri- and postoperative parameters of patients undergoing a cystectomy and try to find risk factors for infectious complications. In detail, we analyze their medical history, demographic data, lab values, microbiological tests as well as histological and radiological findings. Furthermore, after discharging our patients, we send them several follow-up questionnaires at regular intervals and offer them free follow-up examinations.
Characterization of Vaginal, Urinary and Fecal Microbiomes in Women With Recurrent Urinary Tract...
Urinary Tract InfectionsMenopauseThe objectives are to evaluate whether variations in vaginal and/or urinary and/or fecal microbiome predispose postmenopausal women to recurrent cystitis. This will be explored using comparison of microbiome profiles between those with recurrent UTI compared to age-matched women without recurrent UTI.
POS-cUTI: Study on Complicated Urinary Tract Infections
Urinary Tract InfectionsUrinary tract infections (UTI) are among the most common infectious diseases and the most frequent source of community, healthcare-associated and nosocomial bacteraemia. They are associated with significant morbidity and mortality. Due to the high frequency of UTI, they have a major impact on antibiotic use and the antimicrobial resistance of prominent UTI pathogens is of recognised importance. Therefore, UTIs, and particularly complicated urinary tract infections cUTIs, are a target for repurposing of old and neglected drugs, new drug development and non-antibiotic therapeutic and preventive approaches.
Urinary Tract Infection in Patients With Chronic Kidney Disease
Urinary Tract InfectionsChronic Kidney DiseasesThis study aims to investigate the etiology and associated risk factors for UTI in Egyptian chronic kidney disease patients. In addition, to identify the isolated micro-organisms and their sensitivity patterns for better anticipation of treatment regimen.
Urinary Tract Infections in Kidney Transplant Recipients
Kidney TransplantationThe purpose of this study is to better estimate the prevalence of urinary tract infections (UTI) in kidney transplant (KIT) recipients, and especially multidrug resistant (MDR) bacteria. KIT recipients have a higher risk of UTI over the 6 first months following the transplantation. Urine culture was done in a city lab or at hospital. Current data on bacteriuria and candiduria lead mostly to hospital data that are incomplete..
Recurrent Urinary Tract Infections and the Microbiome
Recurrent Urinary Tract InfectionThe primary objective is to determine if polymerase chain reaction (PCR) (UTIP™) is more sensitive in identifying urinary tract infections (UTI's) than standard urine cultures.

Ultrasonography in Children With First Febrile Urinary Tract Infection
Urinary Tract InfectionsIn recent decades, different tests have been recommended by guidelines in the management of first febrile urinary tract infection (fUTI) in children, including kidney ultrasound (KUS), cystography (VCUG) and renal scintigraphy in order to exclude underlying kidney anomalies. The majority of guidelines, continue to recommend a routine KUS for all children at the first fUTI. On the other hand, as this approach is not based on robust evidence, other guidelines suggest that KUS should only be performed on selected patients according to specific risks. Despite being a non-invasive and radiation-free method, KUS tests negative in 83% of cases of fUTIs and possesses low specificity for low grade vesico-ureteral reflux (VUR). Since VUR is the most commonly associated renal malformation with UTI, it is evident that all the guidelines focus on the research of VUR, especially in times when antenatal ultrasound allows to screen for major congenital anomalies of kidney and urinary tract (CAKUT). However, VUR-associated nephropathy appears to be related to primary dysplastic damage rather than to be secondary to the reflux itself and not preventable from antibiotic prophylaxis in terms of recurrence and of kidney scar. To reduce the number of normal VCUGs performed, recent evidence regarding VUR suggests that the presence of pathogens different from E. coli and UTI recurrence may help to identify children who necessitate further investigations. A preliminary retrospective monocentric study enrolling all patients aged 2 to 36 months diagnosed with first fUTI who subsequently underwent US evaluation of the kidneys and urinary tract, found that atypical germ and recurrence of UTI exhibits a 85% sensitivity to detect pathological ultrasound. The aim of this multicentric study is to prospectively evaluate the diagnostic accuracy of the presence of atypical germ combined with the recurrence of UTI in predicting the positivity of KUS in children aged 2 months to 3 years old with first episode of fUTI
