Filter by:This study evaluates the efficacy and safety of an individualized preventive strategy against CMV infection in CMV seropositive heart transplant patients based on the specific basal response of the lymphocytes againts CMV (ELISPOT Interferon-γ assay). In two thirds of the patients a preventive strategy will be carried out based on the result of the ELISPOT IFN-γ assay and in one third of the patients the standard of care strategy will be carried out (universal prophylaxis).
The study investigators are interested in learning more about how drugs, that are given to children by their health care provider, act in the bodies of children and young adults in hopes to find the most safe and effective dose for children. The primary objective of this study is to evaluate the PK of understudied drugs currently being administered to children per SOC as prescribed by their treating provider.
Microbiome in patients affected by pancreatic ductal adenocarcinoma may present specific and identifiable patterns. These variations could affect the surgical outcome and increase the risk of life-threatening infections supported by multidrug-resistant bacteria. The identification of microbial signatures with tumor specificity may have a potential role in postoperative risk stratification. Variation of pancreatic, intestinal or bile microbiome and their relationship can be investigated and measured as promising tools in order to predict and overcome the clinical and infectious burden imposed by MDR infections. The prospect of a potential role for probiotics to promote competition against the pathogens and to improve the gastrointestinal barrier integrity has also been raised. Moreover, if the bacterial composition in human PDAC was confirmed to be distinct from that of the normal pancreas, microbiome variation could be used as a potential biomarker, to assess the potential for malignancy in precursor neoplastic lesions. However, we believe that a preliminary and explorative study is necessary. The study aims to outline the pancreatic microbiome of patients who undergo upfront PD for resectable PDAC and to characterize the possible association between bacterial composition and the occurrence of post-operative complications, particularly POPF and IC.
In adult HIV-positive patients, data on the safety and immunogenicity of the quadrivalent HPV (qHPV) vaccine have been reported with excellent results (13 14); also, the results of a clinical trial of qHPV vaccine conducted in seropositive patients older than 36 years (WLHIV and MSM) have been published. Even now, there is not a trial about immunogenicity and safety of a 9-valent human papillomavirus vaccine in HIV-positive women; for this reason, the investigators plan to conduct this clinical trial. HYPOTHESYS: The administration of Nonavalent HPV vaccine (HPV-9) in adult women living with HIV will produce antibodies against nine genotypes of HPV, thus preventing the acquisition of new infections by those genotypes. Besides, this will prevent the cervical and anal dysplasia in these women.
Safety and Performance Evaluation of Seraph 100 Microbind Affinity Blood Filter (Seraph 100) in the reduction of pathogen load from the blood in septic patients with suspected, life-threatening bloodstream infection
Comparing the incidence of SSI in cases using coated Polyglactin 910 suture with Triclosan and cases using Polyglactin 910 suture without Triclosan in clean-contaminated wound surgery
PENGUIN is a pragmatic multi-center trial investigating the effects of pre-operative mouthwash and perioperative oxygen on the incidences of pneumonia and surgical site infection (SSI) following major abdominal surgery. Patients will be recruited from low and middle income countries and randomly assigned to a trial treatment arms: a) pre-operative chlorhexidine mouthwash and 80-100% FiO2; b) no pre-operative mouthwash and 80-100% fraction of inspired oxygen (FiO2); c) pre-operative chlorhexidine mouthwash and 21- 30% FiO2; or d) no pre-operative mouthwash and 21-30% FiO2.
Each year, around 1500 infected Total Hip Arthroplasties (THA) need non-conservative surgery, remaining an issue for patients and healthcare units. The recommended treatment, relying on cohort reviews and international consensus follows a two-stage protocol. This protocol implies a first surgery to remove all infected implants and at least 6 weeks of antibiotic treatment without implant, then usually an antibiotic-free period and only then a second surgery to put back new implants and start the rehabilitation protocol, with usually more than a week of a second hospital stay. Between both surgeries, full-weight bearing is prohibited and joint stiffness and/or pain are rather usual complications. Failure rate is estimated at 10% in this two-stage strategy. The single-stage procedure (i.e. implanting back a new prosthesis during the same surgery after implant removal, synovectomy and lavage) is thought to be less susceptible to late functional complications (i.e. pain, stiffness and muscle deficiency) with a shorter, single hospital stay. Although, with single-stage surgery, infection control could be less efficient because most pathogens produce during the first hours of infection an antibiotic-resistant layer called biofilm, allowing them to colonize and adhere to foreign objects like implants. This single-surgery protocol thus highly relies on antibiotics and has a list of contra-indications (based on experts' consensus): the presence of damaged soft tissues or a sinus tract, unknown pathogens, difficult to treat micro-organisms, severe immunosuppression and for many surgeons, each time a bone graft is necessary. Most of these contra-indications are directly related to the biofilm. As no randomized control trial has ever compared single-stage versus two-stage surgery, the level of evidence for recommending one procedure over the other is low. We conducted a survey that showed that most of the French reference centers have already switched to single stage surgery for single-stage non contra-indicated cases. An antibiotic-loaded hydrogel coating (Defensive Antiadhesive Coating®, Novagenit SRL), has been proven to mechanically prevent the biofilm formation, while allowing a prolonged intraarticular antibiotic release, in a randomized controlled trial in primary prevention of infection in THA. The addition of this biofilm inhibitor to a single-stage surgery might stand as a promising strategy for secondary prevention of peri-prosthetic hip joint infection. Moreover, using this device to prevent biofilm formation could expand one stage surgery to patients that are "normally" contra-indicated to one stage surgery.
Lower Respiratory Tract infections are a common cause of admission to the intensive care unit. Children routinely receive antibiotics until the tests confirm whether the infection is bacterial or viral. The exclusion of bacterial infection may take 48 hours or longer for culture tests on biological samples to be completed. In many cases, the results may be inconclusive or negative if the patient has already received antibiotics prior to the sample being taken. A rapid assay to detect the most likely cause of infection could improve the speed with which antibiotic therapy is rationalised or curtailed. This study aims to assess whether a new genetic testing kit which can identify the presence of bacteria and viruses within hours rather than days is a feasible tool in improving antibiotic prescribing and rationalisation of therapy in critically ill children with suspected lower respiratory tract infection.
The purpose of this study is to assess whether a 5-day treatment with orally administered prednisone provides patient-relevant benefits by improving the cough-related QoL of patients with post-infectious cough triggered by an Upper Respiratory Tract Infection (URTI) and seeking care in adult primary care practices. The study aims to describe an efficacy and safety profile for a 5-day prednisone treatment compared to a 5-day course of placebo.
