Active clinical trials for "Infections"

To evaluate the safety and effectiveness of oral sodium fusidate (CEM-102) as chronic antibiotic for the treatment of bone or joint infections.

Background: Hospital acquired pneumonia (HAP) is divided in two distinct groups, ventilator-associated pneumonia (VAP) and non-ventilator-associated HAP (nvHAP). Although nvHAP occurs more frequently than VAP and results in similar mortality and costs, prevention guidelines and prevention focus almost exclusively on VAP. Scientific evidence about nvHAP prevention is scarce. Therefore, we designed a mixed-methods study to investigate the effectiveness of a newly developed nvHAP prevention bundle and factors that influence its implementation. Methods: This single-centre project at the 950-bed University Hospital Zurich (UHZ) will engage the wards of nine departments with substantial nvHAP rates. The nvHAP bundle consists of five primary prevention measures: 1) oral care, 2) identification and treatment of patients with dysphagia, 3) mobilization, 4) stopping unnecessary proton pump inhibitors, and, 5) respiratory therapy. Implementation includes the engagement of department-level implementation teams, who sustain the 'core' intervention components of education, training, and environmental restructuring and adapt the implementation strategy to local needs. The effects of the implementation will be analysed by a mixed-method approach. As primary outcome, nvHAP incidence rates will be analysed by Poisson regression models to compare incidence rates before, during, and after the implementation phases (on the hospital and department level). In addition, the association between process indicators and nvHAP incidence rates will be analysed using longitudinal Poisson regression models. A longitudinal, qualitative study and formative evaluation based on interviews and focus groups identifies supporting or hindering factors for implementation success in participating departments dynamically over time. This accumulating implementation experience will be constantly fed back to the implementation teams and thus, represents an active implementation element. Discussion: This comprehensive mixed-methods study is designed to accomplish both, measure the effectiveness of a new prevention bundle against nvHAP and provide insights into how and why it worked or failed. The results of this study may contribute substantially to patient safety in the area of a rediscovered healthcare-associated infection - nvHAP.

Over the last decade, there has been great emphasis on reducing the incidence of hospital-acquired infections, including catheter-associated UTI (CAUTI). This study will evaluate the effectiveness of Betadine irrigation solution (2% povidone-iodine) instilled into the bladder immediately prior to indwelling catheter removal to decrease the risk of subsequent bacteriuria, leading to decreased rates of NHSN defined CAUTI.

This is a Phase 2, open label study (Study number VP-102-105; referred to as COVE-1 [Cantharidin and Occlusion in Verruca Epithelium]) to evaluate the efficacy, safety and tolerability of VP-102 treatment in subjects with common warts. This study has two Cohorts.

Pilot study the aim of which is to obtain reliable data on the tolerance, compliance and efficacy of Tedizolid used as prolonged (≥ 6 weeks) monotherapy or in combination therapy for the treatment of patients with orthopedic device infections due to Gram positive cocci.

Fecal microbiota transplantation (FMT) is acknowledged as a highly effective treatment for recurrent Clostridium difficile infection (CDI). Usually single fecal infusion achieves satisfactory cure rates of recurrent CDI). However, several retrospective studies show that severe clinical picture of recurrent CDI is a risk factor for the failure of single-infusion FMT, suggesting that multiple fecal infusions are required to cure this condition. This is an open-label randomized clinical trial aiming to assess if multiple-infusion FMT is more effective than single-infusion FMT in curing severe CDI

Rifampicin is an antibiotic usually required to treat susceptible Staphylococcus spp. osteo-articular infections, most frequently in association with a fluoroquinolone when the strain is susceptible to both agents. It is the reference treatment for orthopedic infections with implanted material. For tuberculosis treatment the dosage of 10 mg/kg/j is usually prescribed, while in the treatment of Staphylococcus spp. infections the highest dosage of 20 mg/kg/j is proposed by French experts' recommendations from 2009. However, there is little evidence in the literature, which could set out arguments to choose the best dosage of rifampicin, which may vary from 5 to 20 mg/kg. The issue with rifampicin is side effects, in particular with long-term treatment. Many side effects may occur in 10 to 20% of patients and sometimes leads to dosage reduction or treatment interruption. In the literature, there is little evidence that higher rifampicin dosage is associated with higher frequency of adverse effects. Depending on the nature of the toxicity, one could say that hypersensitivity could be independent from dosage, when digestive disorders may be related. Plasmatic concentrations studies have not given strong arguments to link higher rifampicin dosages with side effects occurrence rates. After oral absorption, plasmatic peak occurs after two to five hours and varies among individuals but also in the same patient overtime. This particular pharmacokinetic profile could explain discrepancy in adverse events (AEs) frequencies.

Anti-HIV drugs cut down the number of serious infections that people with HIV get. However, some subjects taking anti-HIV drugs do not achieve adequate cluster of differentiation 4 (CD4) recovery and decrease in elevated cluster of differentiation 8 (CD8) cells. Such patients with a low CD4/CD8 ratio remain at risk for developing acquired immune deficiency syndrome (AIDS) and non-AIDS-related complications. Two of the most important factors associated with low CD4/CD8 ratio include: the persistence of HIV on ART and inflammation. Metformin, the most widely used medication to treat type 2 diabetes, is well tolerated with minimal side effects. It has been linked to anti-aging and weight reducing properties in non-diabetic persons. Because of its ability to improve immune functions, metformin could be a promising addition to ART in HIV patients. It is also reported to change the composition of microbes in the gut which may improve inflammation. PURPOSES OF THE STUDY The purposes of this study are to find out if: metformin can be combined with anti-HIV drugs to reduce the amount of hidden virus in the body; metformin can be combined with anti-HIV drugs to improve immune function. metformin can be combined with anti-HIV drugs to impact CD4 T cell count and CD4/CD8 T cell ratio during treatment and after its discontinuation metformin can change the composition of the bacteria in the gut which may improve inflammation. For this purpose, the investigators will add metformin at the usual antidiabetic dose for 12 weeks for patients receiving stable ART, having a CD4/CD8 ratio below 0.7. Approximately 22 participants will be enrolled in this study at the Chronic Viral Illness Service of the McGill University Health Centre, the Ottawa Hospital and the Maple Leaf Medical Clinic (Toronto). This study will last about 24 weeks; metformin treatment will be for 12 weeks. In order to be eligible for the study, the participants must be 18 years of age or older, have an undetectable viral load (the quantity of the HIV virus in the blood must be less than 50 copies/ml) for at least 3 months and have a CD4/CD8 ratio of less than 0.7. All participants will also be asked to give blood and stool samples and optional colon mucosal biopsy samples (before and after metformin supplementation) to study the size of the viral reservoir and the amount of T cell activation and changes in gut microbiota composition.
