Filter by:The purpose of this study is to evaluate the safety and antiviral activity of ABT-450/ritonavir/ABT- 267 (ABT-450/r/ABT-267; ABT-450 also known as paritaprevir; ABT-267 also known as ombitasvir) and ABT-333 (also known as dasabuvir) with and without ribavirin (RBV) in patients with chronic hepatitis C virus genotype 1a (HCV GT1a) infection without cirrhosis.
Although the accumulated knowledge regarding Cytomegalovirus (CMV) infection increased substantially over the past years, several issues still deserve further investigation. The epidemiology of this disease has been changing, perhaps influenced by new immunosuppressive strategies currently used and growing and widespread use of prophylaxis. The knowledge of the CMV viral load kinetics, using a polymerase chain reaction (PCR-based assay), among renal transplant recipients not receiving any prophylactic therapy will allow the determination of risk factors for and the impact of earlier intervention on CMV infection and disease. The goal is to ultimately improve the clinical outcomes for renal transplant recipients.
The purpose of this study is to evaluate the efficacy of collagen cross-linking for treatment of infectious keratitis.
JUC is a commercially available wound care spray. It is evaluated for the efficacy when using as a hygienic hand rub following the protocol described in the European standard EN 1500:1997 "Chemical disinfectants and antiseptics - Hygienic handrub - Test method and requirement (phase 2/step 2)". A crossover study to compare the JUC solution with 60% (v/v) propan-2-ol by using Escherichia coli K12 NCTC strain 10538 as test organism.
The purpose of this study is to evaluate the efficacy and safety of itraconazole sequential therapy (intravenous injection/oral solution) in participants with invasive pulmonary fungal infections ([IPFI]; lung diseases caused by fungal infection).
The goal of this clinical research study is to learn if the antiviral combination of telaprevir, pegylated Interferon Alfa 2a (PegIFN alfa-2a) and ribavirin (RBV) can prevent the virus from coming back after the liver transplant. Telaprevir, PegIFN alfa-2a, and RBV are different antiviral drugs that work in combination at different stages of the HCV infection to stop the virus.
Background: Vascular grafts are increasingly implanted due to an increasing prevalence of atherosclerosis and diabetes, and about 1-6% of vascular procedures are complicated by infection. Mortality attributable to prosthetic vascular graft infections (PVGI) is high. However, there are almost no data regarding best treatment options of such complicated infections. Most recommendations are based on expert opinion and not on clinical trials or cohort observational data analyses. Evaluating infectious and other complications after vascular surgery procedures are important, and additionally, such studies may offer insights for quality improvement and improved patient outcomes. With the first aim investigators will establish an infrastructure for studying PVGI in Zurich. Investigators will take advantage of the Swissvasc registry, a central registry which collects preoperative, operative and discharge data regarding the index vascular surgical interventions. They will create a prospective observational cohort database of all patients who receive a vascular graft (peripheral, aortic, vein) at the University hospital of Zurich (VASGRA Cohort A). Patients with a PVGI will be included in VASGRA Cohort B and followed up using a flow chart with a focus on the course of this infectious complication. Additionally, investigators will establish a biobank with the collection of tissue- and blood samples of patients with PVGI. With the second aim researchers will investigate different diagnostic, clinical and therapeutic research questions nested in the VASGRA Cohort. Firstly, they will address epidemiological questions, such as: determine the incidence and outcome of complications after vascular graft placement; determine risk factors, best treatment strategies and outcome of PVGI, and determine the influence of different antibiotic regimens on the outcome of PVGI due to different bacterial pathogens. Secondly, investigators will determine the accuracy of different imaging techniques (PET/CT and MRI) for the diagnosis of PVGI, and their individual role for the assessment of treatment response. Thirdly, investigators will evaluate the bacterial diversity of vascular wound infections using 16s r-Ribonucleic acid (RNA)amplification, and investigators will explore whether this bacterial diversity does predict disease progression. Here, investigators will also study the impact of negative pressure wound therapy (NPWT) on bacterial diversity in the treatment course of PVGI. Fourthly, investigators will look for cut-off levels of relevant blood leucocytes count, C-reactive protein and procalcitonin raising suspicion of a PVGI. Lastly, investigators will look at histopathological features of excised vascular grafts. Expected value of the project: Results from the proposed study are an important contribution to the field, based on the large sample size, longitudinal design and by unifying clinical and epidemiological science. The very well characterized patient groups and the close connection between vascular surgeons, infectious disease specialists, specialists in nuclear medicine and microbiologist will help to investigate PVGI in depths. Investigators hope to be able to develop guidelines regarding best diagnostic modalities and treatment options in case of vascular graft infections. In the future we plan to examine bacteria retrieved from the PVGI in the laboratory in detail. The recovered bacteria will be examined for antimicrobial susceptibility and their capability to form biofilms. Furthermore investigators will examine how bacterial recovery form explanted grafts could be optimized.
This randomized phase III trial studies chlorhexidine gluconate cleansing to see how well it works compared to control cleansing in preventing central line associated bloodstream infection and acquisition of multi-drug resistant organisms in younger patients with cancer or undergoing donor stem cell transplant. Chlorhexidine gluconate may help reduce bloodstream infections and bacterial infections associated with the central line.
The study is a prospective, open randomized, non-inferiority trial with two parallel groups, comparing 6 weeks versus 12 weeks of antibiotic treatment following surgery procedure (debridement and retention, 1-stage or 2 stage exchange). The duration of the treatment antibiotic of prosthetic joint infections is only based on experts' opinion ; this one varies from 6 weeks to several months according to the customs of the influencer. The principal aim of this study is to explore the efficacy and safety of 6 weeks versus 12 weeks antibiotic therapy duration, both associated with surgical procedure (debridement and retention of implant, one-stage or two stages exchange), in PJI treatment. The study concerns 410 men or women of more than 18 years include in 34 centres in France. The duration of the study is of 4 years.
This is a biomedical research, prospective, mono centric, tolerance study Of the administration of subcutaneous teicoplanin in the treatment of osteoarticular infections.
