Filter by:This is a prospective single- center observational study in the Leiden University Medical Center in approximately 250 children (<12 years) undergoing elective cardiac surgery, for congenital heart disease. The parents/guardians of the children will be asked to fill out a questionnaire, to asses respiratory symptoms in the last weeks, before the operation of their child. In the operating theatre, a nasopharyngeal swab will collected. Clinical data will be collected daily during paediatric intensive care admission, and date of discharge from paediatric intensive care unit and from hospital are recorded. If children are still intubated at day 4 a second nasopharyngeal swab and residual blood will be collected. The samples will be tested for rhinovirus with a polymerase chain reaction. Main study parameter is the paediatric intensive care unit length of stay in per-operative rhinovirus -positive compared to rhinovirus-negative patients.
The purpose of this study is to investigate the plasma pharmacokinetics (PK) of fidaxomicin (FDX) and primary metabolite OP-1118 in Subjects with Inflammatory Bowel Disease (IBD) and C. difficile Infection (CDI). This study will also compare CDI clinical response to the microbiological response in terms of magnitude of reduction of C. difficile total viable count and spore count during treatment with FDX and if achieved; the time to microbial eradication; determine time to negative CDI toxin assay in stool specimens during treatment with FDX; assess the stool concentrations of FDX and metabolite OP-1118 throughout therapy; assess the length of hospital stay, readmissions and resource utilization for IBD patients receiving FDX; record the incidence and severity of Adverse Events (AEs) and document the impact of treatment on Quality of Life as measured by the changes in Short Inflammatory Bowel Disease Questionnaire (IBDQ) score.
Subjects will receive an oral dose of SER-109 in 4 capsules once daily for 3 consecutive days. The purpose of this study is to provide access to SER-109 for adult subjects with recurrent Clostridioides Difficile Infection (RCDI) and to monitor subject safety and report to regulatory authorities, as appropriate.
Background: - Inflammation is how the body reacts to infection or injury. Infections or inflammation in the brain and nerves can be serious. There aren t always good tests to detect this. Researchers want to learn more about how diseases affect the brain and nerves to develop better tests and treatments. Objective: - To learn more about how inflammation and infections hurt the brain and nervous system. Eligibility: - People at least 2 years old with a diagnosis or suspected diagnosis of nervous system infection or inflammation. Design: - For some participants, a clinician outside of NIH will collect blood, tissue, and other samples. These will be sent to NIH and analyzed. - Other participants will have several visits to NIH. Children may not have all these tests. - Participants will have: - Medical history. - Physical and neurological exam. - Blood and urine samples collected. - Saliva collected. They will chew on a piece of sterile cotton for one minute. - Magnetic resonance imaging (MRI) scan. The scanner is a metal cylinder in a strong magnetic field. Participants will lie on a table that slides in and out of the cylinder. Participants will get a contrast agent through an intravenous (IV) catheter during the MRI. A needle will be used to guide a thin plastic tube (catheter) into an arm vein. - Lumbar puncture. Skin will be numbed and a needle will be inserted into the space between the bones in the back. Fluid will be removed. - Some participants may have optional study procedures. These may include eye tests, memory and thinking testing, tests with electrodes on the head, or skin biopsy.
Hepatitis B virus (HBV) infection can result in a greater risk of adverse outcomes in HIV-infected individuals, including more rapid progression to cirrhosis and associated complications such as hepatocellular carcinoma. For this reason, as well as the shared routes of transmission between the two viruses, UK and International guidance recommends that all HBV-negative HIV-infected individuals be offered vaccination against HBV. Unfortunately, response rates in this population can be as low as 17.5 - 40% to standard vaccination courses. To improve this response, strategies such as the use of double dose of standard vaccines (e.g. Engerix B) is recommended in several guidelines for previous non-responders, although there is currently limited evidence for this approach. An alternative strategy is to use vaccines with novel adjuvants such as Fendrix and observational clinical data in the Investigators HIV cohort suggests that response rates can be as high as 81% of individuals achieving HBV surface antibody (HBsAb) levels >100 in a group that did not respond to previous standard HBV vaccine courses. However, the cost of Fendrix is considerably higher than Engerix B and controlled trials are required to confirm whether this approach is warranted. Furthermore, insights into the potential mechanisms by which Fendrix may elicit better responses would be valuable in optimising future vaccine strategies in this population. The Investigators propose to conduct a randomised, open label, active-controlled pilot study comparing double dose Engerix B and Fendrix in HIV-infected non-responders to standard HBV vaccine courses, which will provide the necessary data to design and power a larger multicentre randomised controlled trial. Outcome measures will include the proportion of individuals seroconverting with HBsAb levels >100 following each vaccination course, the magnitude and quality of the HBV-specific CD4+ T-cell responses elicited by each vaccine and the durability of the HBsAb response at 1 year following the end of vaccination.
Surgical site infection (SSI) is the most frequent complication in patients that undergo abdominal surgery. A previous prospective observational study in 167 patients undergoing elective open abdominal procedures showed that case-relevant communication protects from organ/space SSI whereas case-irrelevant communication during the last 20 minutes of the procedure is a risk factor for incisional SSI. Therefore, the introduction of a clinical applicable intervention "structured briefing using the StOP protocol" has been developed and was tested in pilot experiments. This intervention aims at improving case-relevant communication during the procedure and to reduce excess case-irrelevant communication at the end of an operation. The hypothesis is: structured briefings during an operation reduce the incidence of SSI after surgery.
The main questions being addressed are (1) how patient reported outcomes change during treatment for HCV, (2) how treatment impacts liver function and liver status, and (3) how much treatment costs from the payer's perspective and the patient's perspective. The hypothesis being tested is that treatment has a negative effect on the quality of life during treatment. The negative effect is expected to be temporary. Successful treatment, which is equated with a virological cure of the infection, is expected to result in an improvement in quality of life compared to baseline and to improvement in markers of liver function and liver status. Costs of treatment are expected to be $80,000-$200,000 per virological cure.
The primary objective of this study is to evaluate the efficacy of 2 different doses of intravenous and oral Debio 1450 compared with intravenous vancomycin and oral linezolid in the treatment of patients with staphylococcal ABSSSI.
The purpose of the study is to compare different approaches for the treatment of prosthetic joint revisions and to optimize the outcomes in patients with prosthetic joint infections (PJI) by improving the treatment concept of PJI.
This study will investigate the treatment of urinary tract infection (UTI) in men. The investigators are looking to see if shorter duration of antibiotics (7 days) is not inferior to a longer duration of antibiotics (14 days). The investigators will also study whether longer treatment leads to an increase in antibiotic resistant bacteria in the gut microbiota or an increase in drug side effects.
