Active clinical trials for "Infections"

INVICTUS PED primary objective is to show the non-inferiority of an empirical antibiotic therapeutic management guided by the early detection of integrons in the urine, compared to a usual empirical antibiotic treatment, for the recovery of children admitted to the pediatric emergency department (ED) with a non-severe urinary tract infection (UTI) with fever

Background: Epstein-Barr virus (EBV) causes most cases of infectious mononucleosis (mono). Up to 1 in 10 people who get mono can have fatigue that lasts more than 6 months. One out of 100 people can have severe complications. EBV is also associated with several types of cancer. Researchers want to test an EBV vaccine. Objective: To test the safety of and immune response to a new vaccine against EBV. Eligibility: Healthy adults ages 18-29 Design: Participants will be screened with a medical history and physical exam. They will give a blood sample. Screening tests will be repeated during the study. Participants will get a dose of the study vaccine as an injection in a muscle in the upper arm. They will be observed for 30 to 60 minutes. Blood pressure, heart rate, breathing rate, and temperature will be checked. The injection site will be examined. Participants will get a diary card. They will write down any side effects they have after the vaccine dose, or they may use an electronic diary card. Participants will be asked to write down or enter any important medical events that may occur at any time during the study. Participants will get a vaccine dose at 2 more study visits. They will have 4 follow-up visits at different times after a vaccine dose. Participants will have 6 telephone calls in between the in-person visits. They will also have 1 telephone call 1 year after the third dose of vaccine. If possible, this visit can occur in person. Participation will last about 18 months. There is an optional in-person visit or telephone call 2 years after the third dose of vaccine.

The increasing number of persons >65 years of age form a special population at risk for nosocomial and other health care-associated infections. The vulnerability of this age group is related to impaired host defenses such as diminished cell-mediated immunity. Lifestyle considerations, e.g., travel and living arrangements, and residence in nursing homes, can further complicate the clinical picture. The magnitude and diversity of health care-associated infections in the aging population are generating new arenas for prevention and control efforts. Common infections leading to hospitalizations in this age group result in respiratory infections and bacteraemia and the impact of these infections on the quality of life and disability in aged populations has not been accurately quantified in a European setting. This study aims to capture and quantify the impact of infectious diseases on quality of life in an aged population.

This study is a human challenge study to assess the feasibility and safety of controlled human malaria infection (via P. vivax sporozites) in healthy volunteers, and to develop a bank of P. vivax-infected blood for use in future controlled human P. vivax malaria infection studies. Additional objectives are to obtain data on host immune response to P. vivax infection and pre-treatment gametocytaemia. This study is funded by the UK Wellcome Trust. The grant reference number are Oxford/MORU: 212336/Z/18/Z and 212336/Z/18/A, and Mahidol University: 212336/A/18/Z and 212336/A/18/A.

The purpose of this research study is to identify the effects of 2 over-the-counter mouthwashes on bacteria and 3 viruses in the participant's mouth and gut. The participant will be randomly allocated to rinse their mouth twice daily either with Listerine mouthwash, Lumineux Oral Essentials mouthwash, or water. The overall duration of the study will be approximately 180 days and will include approximately 5 visits and 15-30 minutes for each visit with a total of approximately 2.5 hours of your time. Additionally, fecal matter will also be collected in some subjects using a commercial collection kit.

This is a phase 1, Single-Center, Double-Blind, Randomized, Placebo-Controlled, dose escalation, clinical trial enrolling 24 healthy participants. The main subject is to investigate the safety and tolerability of the LABTHERA-001 capsule and to explore the acceptability of the capsule.

The investigators will perform single-dose pharmacokinetic (PK) studies in humans following administration of drugs with known microbiome derived metabolism (MDM) in parallel with preclinical studies. By directly comparing laboratory measurements to clinical results, the investigators will be able to confirm the relevance of MDM in vivo, create microbiome-dependent PK profiles of the MDM positive drugs, and establish methodology to capture the contribution of MDM to inter-individual variability in clinical drug PK profiles.

The purpose of this study is to evaluate the pharmacokinetics of a single dose of intravenous or oral omadacycline in children and adolescents with suspected or confirmed bacterial infections.

A cluster-randomised multicentre blinded clinical trial will be performed in six primary care centres located in the southern metropolitan area of Barcelona (Spain). The objective is to assess whether including experts on infectious diseases (ID) within the antimicrobial stewardship (AMS) team of primary care achieves higher reductions on overall antibiotic consumption and increases the quality of prescription in diagnosed upper respiratory and urinary tract infections. Centres will be randomly assigned to receive a standard-AMS or an advanced-AMS (intervention). Advanced-AMS includes all standard-AMS strategies plus general practitioner chance to discuss clinical cases by telephone to ID expert on working days (8:00 am to 8:00 pm), and by biweekly meetings.

A phase I, experimental dose finding, open label, clinical infection, safety and viral detection optimisation in previously SARS-CoV-2 infected (unvaccinated or vaccinated) or uninfected vaccinated volunteers.
