Filter by:The goal of this open-label clinical trial is to evaluate the safety and immunogenicity of INAVAC (Vaksin Merah Putih - UNAIR SARS-CoV-2 (Vero Cell Inactivated)) Vaccine as Homologue Booster in Adult Subjects in Indonesia. The main question it aims to answer is: "To evaluate the humoral immunogenicity profile at 28 days following vaccination with INAVAC vaccine as homolog booster administered intramuscularly in healthy adults age 18 years and above". Participants will be administered one dose of vaccination for the third dose (booster vaccination) intramuscularly.
A prospective observational study that will be conducted in Tangerang Regency, Indonesia with primary objective to determine the clinical characteristics, specific immune responses, and viral serotypes in patients with confirmed dengue virus infection in Tangerang District, Indonesia.
There has been no effective predicting tool to accurately predict BKV reactivation after kidney transplantation. The aim is to elucidate the use of flow cytometric analysis for both intracellular cytokines and surface activation markers for BKV-specific T cell response in kidney transplant recipients.
The goal of this decentralized, observational study is to enroll and observe adults in the contingent United States during the 2023-2024 flu season. The main study objectives are to create a dataset of paired wearable data, self-reported symptoms, and respiratory viral infection (RVI) from PCR testing during the 2023-2024 flu season and to develop algorithm that is able to accurately classify asymptomatic and symptomatic RVI and understand the algorithm's performance metrics.
This study investigates the effect of Lactobacillus reuteri probiotic strains (ATCC PTA 5289 and DSM 17938) on symptoms of viral upper-respiratory tract infections in children.
Influenza and other acute respiratory viral infections remain practically uncontrollable diseases due to the high variability of the antigenic structure of influenza viruses and the heterogeneity of pathogens of acute respiratory infections. Therefore, for the prevention and treatment of influenza, acute respiratory viral infections and herpes infections, it is relevant to develop drugs - immunomodulators that mobilize the reserves of nonspecific and specific immune systems and enhance the effects of these systems against the pathogens. The drug CYCLOFERON, 150 mg, enteric-coated tablets, contains the active substance meglumine acridone acetate, which is an interferon inducer. Interferons are the most important system of innate immunity, which has antiviral and immunomodulatory effects, and can protect the body from infection with a virus, and in case of infection, fight the causative agent of the disease. The planned clinical trial of the efficacy and safety of the drug CYCLOFERON in the dosage form of a tablet will study its ability to prevent influenza and other respiratory viral infections in adults who have already had close contact with patients with manifest disease.
Objectives: 1. To compare the immune response of patients with or without sepsis presenting to the ED with a(n) (suspected) infection. 2. To determine immune response aberrations that are associated with an increased risk of developing sepsis in patients presenting to the ED with a(n) (suspected) infection without sepsis. 3. To determine the long term cognitive and physical sequelae of sepsis after admission.
A randomized, Phase 2a, double-blind, placebo-controlled study to evaluate the safety, pharmacokinetics and antiviral activity of multiple doses of orally administered EDP-323 in healthy subjects infected with RSV-A Memphis 37b. This study is designed to assess the antiviral effect of EDP-323 compared to a placebo control in the respiratory syncytial virus challenge model.
The goal of this prospective, interventional, single-center study is to assess whether the early detection of Influenza with smartwatch algorithms and alerting, rapid testing, and subsequent Baloxavir treatment demonstrate better post-infection outcomes versus publicly available- and Centers for Disease Control (CDC)-derived national statistics for equivalent household populations as well as pediatric kidney, heart, liver, lung transplant recipients and waitlisted patients.
The characterization of the bacterial or viral etiology of an infectious event is required for both isolation decisions and rationale use of antibiotics. In emergency room (ER), the direct identification of the causal pathogen is rarely available in real-time. Alternative is the identification of the host-response to either a bacterial or viral infection. One of this host-response is the expression of peripheral leukocytes cell surface markers, measured by flow cytometry. Investigators and others have reported the high diagnostic performances of combination of cell surface biomarkers to differentiate bacterial from viral infection. The CYTOBACT study aims to confirm on a 500 patients multicentric cohort (200 having already been collected during another study: SEPTIMET), the best combinations for this diagnostic issue. The study will be conducted in 3 emergency departments of APHP hospitals network in Paris, France. Patients with a suspicion of infection will be proposed to participate. No intervention will be introduced during the routine care in the (ER) which will be let at the discretion of the treating emergency physician. During the routine blood sampling in the ER, an additional 30 ml volume of whole blood will be collected, centrifugated, aliquoted and stored at -80°C for further measurement of the expression of a panel of cell surface markers. The participants will be followed up during their hospitalization (if any) and no longer than 28 days. Clinical data at admission, usual blood tests and all microbiological investigations performed during the hospital stay will be recorded into an electronic case record form (eCRF). Based on all those recorded data (excepted the results of flow cytometry for cell surface biomarkers) 2 independent adjudicators will qualify the infectious episode into bacterial,viral or no infection, and (if any) into infection, sepsis or septic shock (according to Sepsis 3.0 definitions). Using different "machine learning" statistical tools, all the combination of the cell surface biomarkers will be tested to select those with the highest performance to differentiate bacterial from viral infection.
