Filter by:This study will determine whether HIV treatment that is initiated during the acute phase of HIV infection, followed by discontinuation of treatment, is effective in reducing the amount of HIV and an increasing the amount of CD4 cells in the blood of people with HIV, compared to the amounts of HIV and CD4 cells in people who do not receive treatment at this stage.
This is a follow-up of a previous dose-ranging study aimed at investigating 2 doses of the trivalent inactivated split virion influenza vaccine when administered by intradermal route with that of the current pharmaceutical presentation administered by intramuscular route. Primary Objective: To assess the immunogenicity of two pharmaceutical presentations of the trivalent inactivated split virion influenza vaccine 21 days after a single injection in subjects aged 18 to 57 years. Secondary Objective: To evaluate the safety profile during the 21-day period following each vaccination in each study group
This study aims to evaluate new dosage of inflammatory markers or new inflammatory markers for the diagnosis of nosocomial bacterial infection. We made the hypothesis that these new dosages or new inflammatory markers could be more useful than dosage of inflammatory markers already used in clinical practice (especially the use of a combination of interleukins (6 or 8) and C-reactive protein for the management of newborns with a clinical suspicion of nosocomial bacterial infection and especially could allow to avoid excessive treatment with antibiotics
The present study was conducted to study the impact community acquired respiratory virus (CARV) infections in an outpatient setting on graft function of lung transplant recipients. The study was aimed to identify risk factors for CARV infections. The study was further intended to investigate an association of Epstein-Barr virus (EBV), cytomegalovirus (CMV) and human adenovirus (HAdV) with the development of BOS and to identify risk factors for virus detection in blood.
The purpose of this study is to investigate the expression of protein biomarkers in cervical vaginal fluid in women with preterm premature rupture of membranes (PPROM)
The purpose of this study is to collect clinical specimens and corresponding clinical data to develop a non-invasive test for detection of intra-amniotic infection and prediction of preterm birth in women and intact amniotic membranes. The specimens collected will be used to develop a specific biomarker panel and algorithm using immunoassays for optimal detection of intra-amniotic infection in women with preterm labor and intact amniotic membranes.
Sepsis is a common cause of morbidity and death in intensive care units. Clinical and laboratory signs of systemic inflammation, including changes in body temperature, tachycardia, or leukocytosis, are neither sensitive nor specific enough for the diagnosis of sepsis. The diagnosis of sepsis is difficult, because clinical signs are unspecific. These signs include tachycardia, leucocytosis, tachypnoea, and pyrexia, which are collectively termed a systemic inflammatory response syndrome (SIRS). SIRS is very common in critically ill patients, being found in various conditions including trauma, surgery, burns, pancreatitis, post-cardiac arrest syndrome, cardiac surgery. Microbiological culture can be used to distinguish sepsis from non-infectious conditions. However, this method lacks sensitivity and specificity, and there is often a substantial time delay. So these signs can also be misleading because critically ill patients often present with the systemic inflammatory response syndrome without infection. This issue is of paramount importance, since therapy and outcome differ greatly between patients with and those without sepsis; clinicians are often prone to overuse antibiotic therapy being afraid of not treating a potential infection or superinfection. Moreover, the widespread use of antibiotics for all such patients is likely to increase antibiotic resistance, toxicity, and costs. On the opposite, any delay in administration of antibiotics can be extremely detrimental for the infected patient with an exponential increase of the odd ratio for death. Search for early biomarker tools for the diagnosis of infection, initially promising, are quite challenged and controversial nowadays because they can be more related to the inflammation response, irrespective to the insult. Furthermore up to 40% of the infections remain strongly suspected but not bacteriologically documented. Persisting researches are ongoing to find new markers to better discriminate SIRS related to infection process from to SIRS not related to infection. Cytokine profiles using multiplex analysis seems more related to the severity of the SIRS than the trigger of the SIRS (infectious or non infectious diseases). Thus, new tools have been developed to identify bacteria by detecting their DNA by various techniques. These techniques have many potential interests over conventional microbiologic tests by decreasing turnaround time (within a few hours 2-6 hours), reducing inhibitory effects of prior use of antibiotics, detection of slow or fastidious growing organisms. However these tests remain to be validated in a clinical setting. The goal of the current study is to evaluate the diagnostic value of plasma detection of bacterial DNA in ICU patients with a clinical suspicion of bacterial infection.
HIV induced altered representation and function of regulatory T cell subsets (NKT and Treg cells) impair the protective T cell response against M.tuberculosis and disrupts LTBI, thus facilitates faster progression and development of severe forms of clinical TB in HIV-TB co-infection.
The purpose of this phase IIB MedImmune-sponsored study was to evaluate the efficacy of the HPV-16/18 VLP vaccine in the prevention of infection with HPV-16 and/or HPV-18 in adolescent and young adult women. A vaccine that prevents, or even reduces, the incidence of the common types of high-risk HPVs, particularly HPV-16 and HPV-18, could result in significant reduction in the incidence of cervical cancer and cancer-related mortality, as well as a reduction in the incidence of surgical procedures following abnormal Pap smears.
