Active clinical trials for "Infections"

Urinary tract infection (UTI) is one of the most common bacterial infections worldwide. It affects 150 million people annually. Treatment of patients with UTI entails a high consumption of antibiotics and large social and health costs. With this protocol, we want to elucidate alternative treatment methods for especially recurrent urinary tract infection. Bacteria have internal competitiveness (bacterial interference) and it is known that the non-pathogenic E.coli can outcompete the pathogenic E.coli in laboratory studies. We intend to strengthen the clinical evidence that it can be used as patient treatment through a clinical, placebo-controlled, double-blind trial at Odense University Hospital.

In a prospective multi-center observational study, 200 HIV-infected patients treated with antiretroviral treatment (ART) and who suffered from coronary artery disease (CAD) will be enrolled. Blood samples for biological parameters will be collected with all participants: lipid profile and markers of systemic inflammation specific for HIV-infection (lipopolysaccharide-binding protein; cytokines: IL-1β, IL-6, IL-8, IL-10, TNF -α, INF-γ, INF-α; procalcitonin; inflammatory hsCRP). All of them will undergo functional testing (Echo, CMR both at rest and stress if necessary) and invasive imaging with QCA, FFR, QFR, OCT, IVUS, VH-IVUS, NIRS. Patients will be treated according to the current and previous recommendations. Both medical treatment and percutaneous transluminal coronary angioplasty (PTCA) with or without stenting will be done. Collected data will be analyzed: correlation between ART, blood test results, coronary angiography results, including performed PTCA, history of myocardial infarctions, and other cardiovascular events. The follow-up period will achieve 12 months prospectively with collected clinical events and imaging outcomes which will be determined at the baseline and 12-month follow-up. The independent ethics expertise will be provided by the Central Clinical Hospital of the Russian Academy of Sciences (Moscow, Russia). The monitoring of the clinical data with imaging will be provided by The Ethics Board of Central Clinical Hospital of the Russian Academy of Sciences.

11% of the general population undergo total hip arthroplasty (THA) in their lifetime and 7% undergo total knee arthroplasty (TKA), with these rates expected to rise up to 50% by 2026. Periprosthetic joint infection (PJI) remains one of the most common complications, accounting for 30% of THA/TKA revision surgeries. Topical delivery of antibiotic powder may reduce the incidence of PJI but its potential drawbacks include wound healing complications, reduced osteoblast activity, third body wear, and antibiotic resistance. In THA and TKA, topical administration of vancomycin powder for the primary prevention of PJI has been studied in observational studies, but conclusions are limited due to the low incidence of PJI and high number of patients required to detect a significant difference. Investigators therefore propose a randomized controlled trial (RCT) investigating the impact of topical vancomycin compared to standard care on PJI rates following THA and TKA. Aim: To determine whether topical vancomycin is a safe and effective intervention for the primary prevention of PJI after THA and TKA. Study Design: This is a pilot multi-centre RCT to evaluate the study design and assess feasibility prior to implementation across Canada. Investigators aim to recruit 50 THA and 50 TKA patients. Inclusion Criteria THA or TKA Patients aged 18 years or older Patients must complete 1 year follow-up Exclusion Criteria Patients undergoing surgery for inflammatory arthritis, post-traumatic arthritis, or avascular necrosis History or septic arthritis based on history or synovial aspirate Prior major operation on the affected joint Current immunosuppressive medications Vancomycin allergy or history of a vancomycin-related complication Recruitment: surgeons introduce study to the patients, research staff will conduct recruitment. Intervention: Patients will be randomized preoperatively and remain blinded to their treatment arm. Patients allocated to the control group will have all standard care infection prophylaxis interventions. Patients allocated to the vancomycin group will undergo all the standard care measures in addition to 1g of powdered vancomycin applied to the wound. Follow-up: Patients will complete follow-up at 2 weeks, 6 weeks, 3 months, 6 months, and 1 year visits. Primary outcome: PJI in the same joint. Secondary outcome: PJI in THA and TKA subgroups: Reoperation on the same joint Superficial and non-infectious wound complications All complications

The objective of this application is to increase PrEP uptake among AA women at-risk for HIV-infection in the rural South, specifically those seeking care at Federally Qualified Healthcare Centers (FQHC) in rural Alabama. The investigators will use a mixed-methods approach to adapt and pilot test a patient-provider communication tool from the CDC PrEP toolkit that focuses on the first three steps of the PrEP cascade (e.g., recognizing HIV risk, identifying as a PrEP candidate, and interested in PrEP) to increase PrEP uptake via referrals to local PrEP clinics.

This study is investigating the role of allergic (Th2) inflammation in patients with Cystic Fibrosis (CF) and history of fungal infection and/or Allergic Bronchopulmonary Aspergillosis. Little is known about fungal infection in CF and conflicting results exist on whether this results in worse lung function over time. There is concern that persistent fungal infection can result in worse clinical outcome measures in patients with CF. Also, it is unclear how ABPA develops, but may be related to the amount of fungus a patient with CF is infected with. This study looks at inflammatory patterns and allergic responses to fungal elements to help identify biomarkers and signs of allergic disease in fungally infected patients with CF.

This work aims to: Validate the performance of CRP, and PCT in early differentiating IFI from bacterial bloodstream infections. Compare the results of CRP and PCT with the results of β-D- glucan. 3. Find the relationship between biomarkers levels [CRP, PCT and β-D- glucan] and the results of blood culture which is the gold standard of diagnosis.

Acute head and neck infections cause significant pain and discomfort for patients and impact on their quality of life. Effective antibiotic and surgical treatments have been developed for these infections but they are still able to develop into life-threatening diseases such as meningitis and sepsis. The direct cause of acute head and neck infections is often unknown but it has been suggested that they are due to a disturbance of the normal bacterial growing in the mouth or are from dental origin. The most common microorganisms identified from these infections in published studies are a group of bacteria known as viridans group streptococci (VGS). There are over 30 individual species of bacteria in the viridans group and VGS are difficult to identify to the level of a single species because of their variability. There is a lack of species identification within the hospital setting and this project aims to gain a deeper understanding of the microorganisms causing acute head and neck infections, focusing on identification of individual species of VGS bacteria. The investigators will analyse bacterial DNA to determine which species have been identified and will also look at patient data and clinical outcomes (eg. length of hospital stay) to determine if the species causing the infection has any effect on patients.

Orthognathic surgery describes a group of procedures aimed at correcting developmental or acquired deformities of the jaws and facial skeleton. The goal of these procedures is to improve speech, jaw and dental function, aesthetics, and symptoms of sleep apnea. This is accomplished by surgical repositioning of the upper jaw (maxilla) and lower jaw (mandible). The most common procedures are lefort I osteotomies (upper jaw repositioning) and bilateral sagittal split osteotomies (lower jaw repositioning). At our institution, almost all cases include one or both of these two procedures. The majority of cases include bilateral sagittal split osteotomies (BSSO). As access to the jaws is through the oral cavity, these procedures are considered to be clean-contaminated surgeries due to the high intra-oral bacterial load. The result is that surgical site infections (SSIs) occur in 10-15% of cases. Studies show that the vast majority of these infections occur in the lower jaw (BSSO sites), presumably due to pooling of saliva and debris. SSIs are associated with patient discomfort, prolonged hospital stays, increased morbidity, and increased cost to healthcare systems. The use of peri-operative antibiotics has been shown to significantly reduce the incidence of SSI following orthognathic surgery. There is currently no consensus on the dosing or specific antibiotic to be used. There is strong evidence that pre-operative antibiotics significantly decrease SSI compared to no antibiotics. However, to date, there is no good evidence to support the use of post-operative antibiotics to further decrease the rate of infection. Several studies have examined the use of post-operative antibiotics ranging between 1-7 days. The majority of studies were not able to demonstrate a statistically significant difference to justify the use of post-operative antibiotics. A systematic review by Danda and Ravi in 2011 suggested that there likely is a benefit to the use of post-operative antibiotics. Danda and colleagues in 2017 later conducted a trial comparing pre-operative antibiotics alone compared to pre-operative combined with post-operative antibiotics. A statistically significant difference was not found, however, they felt that this was due to a limited sample size. Overall, there is no robust data that supports the use of post-operative antibiotics. The World Health Organization guidelines currently recommend against the use of post-operative antibiotics in orthognathic surgery. However, they do comment that there is some weak evidence that suggests its use. It was deemed that this low quality evidence did not outweigh the potential harm of antimicrobial resistance, which results from inappropriate overuse of antibiotics. Antimicrobial resistance is a serious, growing problem which has deadly consequences. Our current protocol at the QEII Health Sciences Center for peri-operative antibiotic administration is a single pre-operative dose of 2g cefazolin IV, followed by further doses every 8 hours post-operatively for a total of 24 hours (3 post-operative doses). Our study aims to investigate whether there is a need for these additional post-operative doses. If there is a benefit to these additional doses, the research team aims to investigate whether this benefit outweighs the risks. This question is of great importance in order to avoid an unnecessary contribution to antibiotic resistance and unnecessary potential adverse effects. Participants will be assigned a study number and randomly allocated to one of two groups. Group A will receive a single pre-operative dose of 2g IV cefazolin. Group B will receive a pre-operative dose of 2g IV cefazolin, followed by an additional three doses post-operatively every 8 hours for a total of 24 hours. Informed consent will be obtained at each participant's pre-operative assessment in the days leading up to the procedure. The participant will then select a group designation from a sufficiently mixed jar, and group A or B will be assigned to their study number. For each patient, the procedures completed will be documented, along with age, sex, smoking status, length of procedures, and complications. Complications including medication adverse reaction (allergy, toxicity, side effects), surgical complications, and any other significant complications related to the medications or deemed to be relevant to infection risk will be documented. Procedures will be carried out in the standard fashion. Patients will receive the same post-operative instructions and will be discharged with a chlorhexidine mouth rinse to be used for two weeks. Patients will return for follow-up at 2 weeks, 4 weeks, and 6 weeks post-operatively. Surgical site infection diagnosis will be made according to the CDC criteria and will be reported as either superficial, deep, or organ/space infections. Date of occurrence, location of infection, and treatment provided will be recorded on a standard form provided to surgeons.

The purpose of this study is to evaluate the efficacy, safety, pharmacokinetics (PK), neutralizing antibody and antidrug antibody (ADA) response for TNM001 in infants entering their first RSV season.

The primary objective of the study is to demonstrate and quantify the protective efficacy (PE) of a single SR product, in reducing DENV infection and active Aedes-borne virus (ABV) disease in human cohorts. The study design will be a prospective, cluster randomized controlled trial (cRCT). Although not a specific objective of this project, an overall goal is to allow for official recommendations (or not) from the World Health Organization (WHO) for the use of SRs in public health. A WHO global policy recommendation will establish evaluation systems of SR products to regulate efficacy evaluations, thereby increasing quality, overall use and a consequent reduction in disease.
