Filter by:This study is aimed at assessing the safety of candidate Hepatitis C vaccines AdCh3NSmut/MVA-NSmut and HIV vaccines ChAdV63.HIVconsv/MVA.HIVconsv when administered separately or in combination to healthy volunteers. The study also aims to assess the cellular immune response generated by these vaccines when administered as mentioned above.
The concept of acquired immunodeficiency after a first severe infection in the ICU is widely described in the literature. There is a dual risk: increased mortality and increased secondary infections. Several approaches of immunostimulatory treatments have been proposed in the literature. The treatment proposed by this study consists of the administration of Granulocyte-macrophage colony-stimulating factor (GM-CSF), colony stimulating factor widely used particularly in the USA where it is marketed. A phase 2 clinical trial was conducted in Germany in 2009. The main objective is to measure the incidence of ICU-acquired infections in 2 groups of patients treated by GM-CSF or placebo. ICU patients at risk are defined as surviving at D3 from a severe sepsis or septic shock and presenting a sepsis associated immunodepression. The detection of immunosuppressed patients will be achieved by measuring the HLA-DR (Human Leucocyte Antigen DR)with a threshold of less to 8000 sites. Our hypothesis is that the number of secondary infections (primary endpoint) will be significantly reduced in the treated group.
The primary objectives are to evaluate relationship between nasopharyngeal microbial colonization and the occurrence of AOM or pneumonia in infants.
This study was aimed evaluate long-term immunity response by neutralizing antibody test of adults in high risk population of HFRS .
Reverse hybrid therapy is a one-step two-phase treatment for Helicobacter pylori infection with less cost than standard triple therapy. Whether reverse hybrid therapy can replace standard triple therapy as the recommended first-line treatment is unknown. The investigators compared the efficacy of 12-day reverse hybrid therapy and 12-day standard triple therapy in first-line treatment.
Chest physiotherapy (CP) facilitates the absorption of fluid in the pleural cavity and reduces the formation of fibrous adhesions in patients with pleural infection, allowing a faster clinical, functional and radiological improve. The aim of the study is to determine if the CP associated with conventional medical treatment (CT) improves functional sequelae secondary to pleural infectious.
Fluoroquinolones (FQ) are among pivotal antibiotic treatments in difficult-to-treat infections. Their efficacy has been shown to be linked to the ratio area under the curve (AUC) of their plasma concentrations over the minimum inhibitory concentration (MIC) of the bacteria treated. Eventually, Forrest et al., reported in gram-negative infections that an AUC/MIC above 125 conducted to a 80 to 90% clinical success whereas success decrease to 30 to 40% in patients with an AUC/MIC below this threshold. These results have been reproduced recently by Zelenitsky et al. in intensive care unit (ICU) patients with threshold similar to the one obtained by Forrest et al. Lastly, elevated concentrations of FQ should be related with the onset of adverse events. Thus, therapeutic drug monitoring (TDM) of FQ appears of potential interest, particularly in case of severe infections (intensive care unit (ICU) patients) or complicated and cost-related infections (osteoarticular infected (OAI) patients), with an increasing level of evidence of its use. However, FQ TDM requires access to the full AUC of the drug with the need of many samples drawn to patients. This appears to be irreconcilable with clinical practice but can be achieved using population pharmacokinetic (PkPop) modelling. PkPop allows estimating pharmacokinetic parameters of the drug by introducing covariates (demographic, biological, clinical…) and modelling inter-individual pharmacokinetic variability. The model created allows then accessing to individual parameters of patients and thus, estimating concentrations and AUC of the FQ. This approach may also be used in clinical practice to determine a limited sampling strategy allowing an adequate estimation of AUC with a minimum of samples.
The purpose of this study is to evaluate the safety and efficacy of ombitasvir/paritaprevir/ritonavir and dasabuvir with or without sofosbuvir (SOF) and ribavirin (RBV) in DAA treatment-experienced adults with Genotype 1 Chronic Hepatitis C Virus infection. This study will contain 2 parts. Part 1: Approximately 20 participants and at least 10 of the 20 participants previously treated with the combination of ombitasvir/paritaprevir/ritonavir and dasabuvir, with or without RBV, and experienced treatment failure. Part 2: Approximately 10 participants and all participants previously treated with SOF/ledipasvir and experienced treatment failure.
The study aims to address the following aims 1. To provide an overview of the epidemiology of the patients who are managed in the Singapore General Hospital for NTM infections. 2. To evaluate the medical care of patients in the institution with regards to the type of medical and/or surgical treatment received and specifically, the antibiotic regime and duration administered. 3. A longitudinal follow up which will allow an assessment of our care and patient outcome in this population cohort
GSK1265744 (744) is an integrase strand transfer inhibitor (INSTI) currently in development for both the treatment and prevention of human immunodeficiency virus (HIV) infection. Renal elimination of unchanged 744 is extremely low, with no parent 744 detected in the urine after a single 30 mg radiolabeled dose. Despite the minimal contribution of renal clearance on overall 744 elimination, renal impairment may potentially inhibit some pathways of hepatic and gut drug metabolism and transport, and as a result may impact 744 pharmacokinetics. The current Food and Drug Administration (FDA) draft guidance for renal impairment studies suggests that a pharmacokinetic (PK) study in patients with renal impairment be conducted even for those drugs primarily metabolized or secreted in bile. The study will be comprised of two cohorts (severe renal impairment and normal renal function) of 8 subjects each. Upon enrolment, each subject will be admitted to the study center and undergo serial PK sampling following a single dose of oral 744 30 milligrams (mg). Subjects will return to the clinic for follow-up evaluations 10-14 days after the 744 30 mg dose.
