Active clinical trials for "Infections"

Population surveys have shown a positive correlation between increased levels of total serum immunoglobulin E (IgE) and bronchial hyperreactivity. However, it is also clear that exacerbations of asthma are frequently triggered by viral respiratory tract infections, especially those caused by human rhinovirus (RV), also known as the "common cold" virus. This protocol explores the relationship between rhinovirus and allergen/IgE provoked inflammation. Experimental challenges with human (RV) result in more persistent upper respiratory tract symptom scores in asthmatics than in controls. Asthmatics with high levels of IgE also show greater sensitivity to methacholine and higher levels of expired nitric oxide (eNO) than those with low levels of IgE. These data suggest that patients with asthma and high levels of IgE are more likely to have pre-existing inflammation of the airways before virus challenge. This study is being done to determine whether anti-IgE therapy (with omalizumab) will lead to a significant decline in inflammatory biomarkers prior to virus inoculation, and thus reduce the severity of clinical manifestations after an experimental human RV challenge.

HOME FIRST (Home Followed - up with Infection Respiratory Support Team) is an early supported discharge scheme. It will enable patients with lower respiratory tract infection (LRTI) to be provided with high quality safe, effective, efficient patient centred care, tailored to their needs in their own home; aiming to improve the overall experience of the service user, improve patient outcomes and reduce hospital length of stay whilst simultaneously reducing admission rates, an area of major strategic importance to the NHS.

This study will determine the tissue penetration of ceftolozane/tazobactam (Zerbaxa, Merck & Co.), a novel β-lactam/β-lactamase combination antibiotic, into the extracellular, interstitial fluid of soft tissue in diabetic patients with lower limb wound infections. Penetration will be compared with a group of healthy volunteer control participants.

Human papillomavirus (HPV) infection is the most common sexually transmitted infection. The high risk oncogenic types, HPV-16 and -18 are responsible for 70% of cervical cancers. The introduction of vaccination against two major oncogenic genotypes of HPV raises questions about genotype replacement because of the existence of other oncogenic types not targeted by the vaccine. A better understanding of natural history of HPV infection and interaction (competition, synergy) between genotypes are required in order to anticipate this phenomenon. The aims of this study are to characterize HPV infection in young female students and to follow up HPV infection and co-infection dynamics with different genotypes, taking into account both vaccination status and immunity to HPV 16 and 18. The study also focuses on the determination of factors influencing the development of persistent cervical HPV infections. The DyPAVIR-ISHARE study is based on the participation of 5000 young female students, from 18 to 20 years-old, all registered at the Universities of Bordeaux or Versailles Saint-Quentin (UVSQ). The 3-years follow-up includes completion of a self-administrated questionnaire regarding sexual behaviour, socio-demographic characteristics, access to health-care services and, for a sub-group of 1000 students, the taking of genital and oral self-taken samples for the detection and genotyping of HPV (every 3 months). Previously, a pilot phase study (2 visits in 3 months of interval) is set up on 50 young female students from UVSQ in order to test feasibility. This study will provide data to gain insight into the possibility of type replacement. Moreover, this study would provide an overview of HPV vaccine coverage and effectiveness HPV incidence and factors associated with HPV infection and co-infection ; Partners recruitment would allow us to follow HPV transmission dynamics among couples, and in particular, HPV exposure in young adult women. The HPV research won't be limited to virus detection in samples but will indicate the presence or absence of HPV infection. Finally, additional genetic studies could be conducted in order to study genetic susceptibility to HPV infection, to chronic HPV infection and to co-infection. This research project is part of the i-Share program funded by the "Investissement d'Avenir" cohort call.

This randomized phase III trial compares the effectiveness of caspofungin to fluconazole in preventing invasive fungal infections in patients receiving chemotherapy for acute myeloid leukemia (AML). Antifungal prophylaxis is considered standard of care in children and adults with prolonged neutropenia after chemotherapy for AML however the ideal antifungal agent for prophylaxis in children is not known. Caspofungin has activity against yeast and some molds while fluconazole coverage is limited to just yeasts. Adult randomized trials suggest that agents with activity against yeasts and molds are more effective than those with just activity against yeasts. There are limited data to answer this comparative question in children. This study will establish much needed pediatric data to guide clinical decision making on optimal antifungal prophylaxis.

The purpose of this study is to investigate durability of SVR in chronic HCV patients who achieved SVR in the previous study with TMC435-containing regimen and time for resistance associated mutations to return to baseline in chronic HCV patients who did not achieve SVR in the previous study with TMC435-containing regimen.

Pre-exposure prophylaxis (PrEP) is a method of preventing HIV infection through the use of antiretroviral (ARV) medications before exposure to HIV. This study will assess the potential of MVC as a "on demand" pre-exposure prophylaxis, within a strategy for the prevention of HIV infection in men who have sex with men (MSM).

The purpose of this study is to determine the effect of renal impairment on pharmacokinetics (PK) of BMS-914143.

This is an open label, in-use study to assess the warming sensation, acceptability and local tolerability of paracetamol 500 mg + phenylephrine 10mg + Guaifenesin 200 mg syrup, given as a single dose in subjects suffering from symptoms of an upper respiratory tract infection. The purpose is to evaluate the acceptability concerning a warming sensation effect and its potential benefit in the target population. The primary objective is to assess the warming sensation caused by the excipient IFF flavor 316 282, in a syrup containing paracetamol 500 mg + phenylephrine 10mg + Guaifenesin 200 mg per 30 ml syrup. The syrup contains (0.15% w/v) warming flavor. The Secondary Objectives are to assess subject acceptability of the syrup and the safety and tolerability of the syrup. The study will be run in fifty-six (56) subjects suffering from symptoms of an upper respiratory tract infection (URTI) for 7 days or less, e.g. nasal congestion associated with colds and flu symptoms such as pain, headache and/or fever. Subjects must have one or more symptoms per category: mild to moderate body pain, headache, fever or sore throat nasal congestion (blocked nose) with or without rhinorrhea (runny nose) or sneezing productive cough Adolescents will be included in the study population

The study is designed to establish infectivity of Plasmodium falciparum sporozoites (PfSPZ) via intravenous (IV) administration in three groups with different malaria immunity-status: Adults with a history of lifelong malaria exposure without sickle cell trait (HbAA) Adults with a history of lifelong malaria exposure with sickle cell trait (HbAS) Adults without previous malaria episodes without sickle cell trait (HbAA) Initially a dose of 3,200 PfSPZ will be given and the time until thick blood smear positivity after challenge will be assessed. If in any of the groups with a history of lifelong malaria exposure, 50% or less of individuals become thick blood smear positive during the 28 days post injection of PfSPZ Challenge, the dose will be increased 4-fold to 12,800 PfSPZ in this group.
