Filter by:The primary purpose of this study is to assess the efficacy of oral TBP-PI-HBr as compared with intravenous (IV) imipenem-cilastatin with respect to the overall response (combined clinical cure plus microbiological eradication) at the Test-of-Cure (TOC) visit in hospitalized adult participants (≥18 years of age) with cUTI or AP.
The goal of this quasi-experimental multicenter before-after cohort study, phase II study is to evaluate the efficacy of 12-month letermovir prophylaxis in lung transplant recipients (D+/R-) compared to a historical cohort of lung transplant recipients (D+/R-) who received 12 months of valganciclovir prophylaxis to prevent CMV disease."
The human microbiota corresponds to an extremely rich and varied set of microorganisms that colonize our various epitheliums from birth, including the intestine, lungs and skin, where they interact continuously with our immune system. Changes in microbial composition and function, termed dysbiosis, have been linked to alterations in immune responses and to disease development, such as psoriasis. Recent research has shown that the gut microbiota can condition the therapeutic response to checkpoint inhibitors and that fecal microbiota transplant overcomes resistance to these therapy, suggesting a direct role for the microbiota in the ability to shape a therapeutic immune response. Antibiotic exposure during the course of cancer therapy negatively correlates with patients' response to anti-PD-1 treatment response, thus highlighting the link between the enrichment of specific microbial taxa in intestines and the response to immunotherapy. This observation suggests that treatments capable of modulating microbial networks and promoting specific bacterial clades may modulate the host's immune response. Hence, beyond their expected effect in the targeted tissue, part of the therapeutic effect of drugs could rely on this mechanism. In psoriasis patients, observational studies suggest that gut microbiome is altered differently after the use of anti-IL17 or anti-IL23 biologic agents. Main objective: To determine the evolution of microbial composition of fecal samples issued to patients who responded to a biologic agent (IL-17 inhibitors, IL-23 inhibitors) and have stopped their treatment for 2 to 4 weeks before the index date, at baseline and 6 months or clinical relapse after treatment discontinuation Design of the study: Prospective french multicentre observational cohort study Population of study participants: Patients with psoriasis in remission after IL23i or IL17inhibitor treatments and who have stopped their medication for 2 to 4 weeks. Number of participants included: 50 adult patients considered in remission and have stopped for at least 2 weeks and a maximum of 4 weeks, one of the following biologic agent: secukinumab, ixekizumab, brodalumab, bimekizumab, guselkumab, tildrakizumab, or risankizumab
Non-RCT clinical trial comparing 5-ALA photodynamic therapy and CO2 laser for persistent high-risk HPV-related low-grade cervical lesions.
Colistin can be used to treat the infection caused by carbapenem-resistant enterobacteriaceae(CRE). In China, patients diagnosed with Hospital-acquired-pneumonia (HAP)or bloodstream infection caused by CRE are recruited, and randomly assigned to two groups, and in one group the patients accept treatment with colistin, however in another group, the patients accept treatment without colistin. The efficacy and safety of the treatment between the two groups are compared.
All patients who presented with epigastric pain and dyspeptic symptoms will undergo endoscopic gastric biopsies. The patients will be subjected to: Full history taking, clinical examination, liver function tests, renal function tests, CBC, INR, abdominal ultrasonography. About 200 patients diagnosed to have H. pylori by infection by microscopically examined, endoscopic gastric biopsies will be enrolled in our study. All available formalin fixed and paraffin embedded tissue blocks of gastric endoscopic biopsies will be resectioned and stained with Haematoxylin and Eosin. Modified Giemsa stain, and Alcian blue/ PAS stain will be used for verification of Helicobacter pylori and demonstration of intestinal metaplasia respectively. Biopsies will be classified using the Updated Sydney system of classification of gastritis
This study investigates Faecal microbiota transplantation (FMT) in prevention of recurrent urinary tract infections (UTIs) caused either by sensitive E. coli or ESBL-E. coli.
Rationale: Respiratory tract infections (RTI) are a major cause of morbidity in young children in high- income countries and the major cause of mortality in developing countries. Causative bacteria and viruses are regular residents of the nasopharynx of asymptomatic individuals (colonization) and live there together with other presumed harmless commensals, without causing disease. These non-pathological infections/colonization episodes are important for transmission, intermediate step to disease and boost immune responses. The investigators recently validated the use of minimally-invasive nasal sampling methods that can be done at home for the study of host and microbial parameters in adults and children. In this study the investigators will focus on the daily microbial and immunological composition of the nasopharynx during health in relation to symptoms. Primary objective: Associate acquisition of pneumococcal colonisation with levels of pre-existing polysaccharide specific memory B cells. Secondary objectives include: Validate the use of synthetic absorptive matrices (SAM) for detection of respiratory pathogens versus nasopharyngeal swabs (NPS) and saliva; Assess dynamics of URT infection/colonisation and examine its relationship with symptoms, host responses and microbiota; Measure transmission between children and parents and immune responses in parents. Study design: Prospective community-based cohort study.total of 45 children, aged 1-5 years old attending daycare or (pre-)school, will be included, including a pilot of 10 children to assess tolerability. If there are insufficient pneumococcal acquisitions in the study to assess the primary outcome, additional children can be recruited in groups of 3 or 4 children (up to 10). For a subset of participating children, both parents will be asked to self-collect daily saliva during the study. Primary study parameters: Frequency of systemic polysaccharide specific B cells in children that become colonised during the study versus children that do not become colonised Secondary study parameters: Dynamics of respiratory bacteria and viruses during URT infection/colonisation. Presence and load for bacteria and viruses in children in SAM versus saliva and NPS. Local microbiota and immune profiles and association with infection/colonisation and symptomology. For a subset of parents, daily presence and load of bacteria and viruses as well as host immune factors measured in saliva.
the aim of this study is to evaluate the efficacy of employing cefepime (CFM) versus ampicillin/sulbactam (AMS) in lowering the rate of post-cesarean surgical site infections.
The goal of this randomized, open-label, interventional trial is to study the efficacy of treatment for Helicobacter Pylori Infection in Preschooler aged 4-6 by Meiji Yoghurt with LG21. The main question it aims to answer is: - whether the treatment by Meiji Yoghurt LG21 is effective by stool antigen (HpSA) test 140 qualified participants will be enrolled and randomized into 2 groups of the same size (product study group and blank control group). Participants of the product study group will need to eat assigned Meiji Yoghurt for 12 weeks, one bottle each day, while participants of the blank control group won't receive any intervention during the study. Four visits will be made for all participants, and relevant clinical data will be captured and recorded into CTMS (Clinical Trial Management System) for statistical analysis and reporting.
