Active clinical trials for "Infections"

This study is a phase II, parallel, prospective, randomized, double-blind, placebo controlled trial. The present study will aim to address the efficacy and safety of acute administration of triiodothyronine on ICU patients diagnosed with pulmonary infection due to COVID-19 and require mechanical respiratory support or ECMO.

In this study, investigators will determine whether the early addition of HT-CCP to standard treatment improves the clinical outcome (as assessed by the Modified WHO Ordinal Scale) of patients with COVID-19 who are hospitalized but not yet in moderate or severe ARDS.

This is a phase II randomised, multicentre, prospective, open label clinical trial. The trial aims to recruit patients who test positive for COVID-19 who have mild symptoms and therefore can treat their symptoms in the community. Patients who test positive for COVID-19 at hospital may also be able to participate.

Diabetic foot ulcers are frequent with average lifetime risk of 15%, and can lead to bone and joint infections. Current protocols for their management include evaluation of ischemia, assessment of underlying bone infection, sharp debridement, off-loading and use of dressings that promote moist wound healing. Extensive debridement is optimal for wound healing and decreases the risk of recurrence. However, extension of surgical debridement is left at the clinician judgement and thus lacks standardised protocols. Plus, there is currently no known risk factors or specific biomarkers that can help guide the clinician for the extent of debridement or that can predict a recurrence in case of non-extensive debridement. The main objectives of the study are to either unravel a new biomarker, and/or identify risk factors associated with poor prognosis following surgical debridement in diabetic foot ulcers. Histones, more specifically H3.1 subtype, have been associated with sepsis. The main hypothesis is that higher blood levels of H3.1 will be present in participants showing poor prognosis (i.e., having additional surgeries, amputation, death) and that a rise in H3.1 blood levels compared to baseline (before the 1st surgical intervention) would provide an early warning of relapse or treatment failure.

Our bodies are home to millions and millions of microbes (bacteria, fungi and viruses), that live in harmony with us without producing any negative (disease producing) effects. Research is beginning to show that these microbes interact with us to help with our immune system, digestive tract and brain development among many other effects. This community of microbes, known collectively as our microbiome, may commence colonisation while we are developing in the womb and becomes quickly established after we are born. Much remains unknown about how preterm birth affects the development of our microbiome. The goal of this longitudinal observational study is to gather more information of how and from where we get those first few microbes, the pattern in which our microbiome develops, and how intensive care for a preterm baby affects this. The main questions it aims to answer are: How is the gut microbiome of a very premature infant affected by clinical management practices (e.g. antibiotics, probiotics, feeding) and how does it progress subsequently. How do probiotics colonise the preterm gut, and how do they persist once supplementation is discontinued. Samples will be collected from mothers and their infants during the NICU admission including: A rectal swab Meconium and stool Urine Blood Expressed breastmilk Maternal stool Maternal oral swab Maternal vaginal or skin swab (depending on mode of delivery) Samples will be analysed using next generation sequencing techniques to, for example, evaluate microbial composition of the samples or determine functional microbiome-host interactions.

The most severe infectious episodes are managed in intensive care. Classically, a distinction is made between sepsis, an infection associated with an inappropriate, excessive response of the immune system, responsible for organ dysfunction, and septic shock, during which, within the potential dysfunctions, hemodynamic alteration is central, requiring the introduction of catecholamines. The seriousness of these disorders, particularly because of their potential short-term severity, requires immediate treatment. The treatment of severe infections is based on the control of microbial proliferation, particularly bacterial. In this context, the speed of antibiotic therapy is associated with patient prognosis. If the administration of antibiotic therapy is an emergency during severe infections, particularly in situations of septic shock, its choice is decisive in the effectiveness of management and in the prognosis of the patient. Prior to microbiological results, antibacterial treatment is probabilistic. In spite of these numerous parameters, failure of probabilistic antibiotic therapy, due to a spectrum unsuited to the pathogens, is described in 15 to 30% of cases. In order to limit the risk of inappropriate treatment, it is recommended that broad-spectrum antibiotic therapy be used in states of shock of infectious origin. Because of their bactericidal properties, their kinetics of effectiveness, their marked post-antibiotic effect, their bioavailability in the plasma sector, and their synergy with beta-lactams, aminoglycosides are often recommended in combination in the initial probabilistic treatment. Despite numerous studies and extensive international experience with aminoglycosides, their real value in the management of severe infections remains uncertain, leading to contradictory information depending on whether one is interested in their benefit in the treatment of identified infections or in the probabilistic treatment of severe conditions. During the management of severe intensive care patients, the pharmacokinetics of drugs, especially antibiotics, are considerably modified. As a result, monitoring of plasma, or better, tissue concentrations of antibiotics is suggested by learned societies, although their practical realization is still very limited by numerous obstacles. Misuse of aminoglycosides is associated with a risk of acute renal failure, centered on the tubular toxicity of the antibiotic. While the risks associated with inappropriate frequency of administration are currently modest, those associated with high peak concentration, responsible for an increase in the duration of renal exposure, are not well known. COVID-19 is also associated with a high risk of impaired renal function. The effect of aminoglycoside administration in the context of COVID-19 remains unknown. Our goal is to determine whether the presence of COVID-19 associates with an elevated risk of renal failure when prescribing aminoglycoside.

The Phase 2 study will be conducted in adult patients with confirmed Dengue infection and will investigate safety, PK, and pharmacodynamics (PD) in this population. The study will be conducted in several dosing cohorts to enable dose selection for subsequent trials

This is a 1:1 randomized double-blind Placebo-controlled moncenter Phase IV study to investigate whether a successful interferon-free treatment of HCV-infection with ombitasvir/paritaprevir/ritonavir (OBV/PTV/r) in combination with dasabuvir (DSV) improves the patients' attention ability as compared to placebo as measured with the Att Test Sum Score change from baseline to week 12. A total of 30 patients with non-cirrhotic genotype 1b HCV infection will be randomly assigned to receive 12 weeks verum followed by 12 weeks Placebo (arm A) versus 12 weeks Placebo followed by 12 weeks verum (arm B). Patients will be followed up for 48 weeks.

The aim of this study is to evaluate the possibility to repropose marketed drugs as antiviral ones, based on their ability to reverse the transcriptomic signature of the infected cells. This strategy has to be considered is the context of emerging viral diseases and of increase of resistance to antivirals. Concerning infection by Influenza viruses, the main drugs were identified and evaluated on in vitro and in vivo models: diltiazem. Therefore, it will be assess the efficacy of these the drug, compared to placebo, to treat severe flu.

The purpose of this research study is to 1) evaluate the safety of a series of injections with the AGS-004 product in combination with a series of Vorinostat doses and 2) to help scientists evaluate ways of reactivating latent (non-acting) HIV virus and determine if the immune system can be made stronger to eliminate the activated HIV virus.
