This is a prospective, multicentre study in which the diagnostic accuracy of multiple Covid-19 Antigen rapid diagnostic tests will be assessed for COVID-19 case detection using prospectively collected nasal swabs and saliva samples from participants suspected to have Covid-19 infection (with or without symptoms). The study will last approximately 9 months.
The purpose of this study is to confirm and quantify the effects of ElderCraft® elderberry extract on immune health.
Newborn babies and infants are susceptible to infections as their immune system is still immature. Maternal immune factors for example antibodies and immune cells mitigate this vulnerability. They are transferred from mother to child via the placenta during pregnancy or by breast milk after birth and provide protection against infectious diseases. In the case of SARS-CoV-2 it has already been shown that specific antibodies are transferred from mother to children after infection or vaccination during pregnancy. However, to this date it is not known how long such an antibody-mediated protection lasts in children and if this "passive" immunity actually protects infants from SARS-CoV-2 infection in the first months of life. In general, there is still little knowledge about the influence of maternal infections during pregnancy, transfer of maternal immune factors to the child and development of the child's immune system and health in the first months of life. Here, the investigators aim to study transferred immunity (i.e. specific antibodies) against SARS-CoV-2 in children of mothers who received a SARS-CoV-2 vaccination during pregnancy or had a SARS-CoV-2 infection during pregnancy with mothers not exposed or exposed before pregnancy. In addition, the investigators will comprehensively characterize the development of the cellular immune system in the first year of life (umbilical cord blood, age 6 and 12 months) to explore how maternal exposure to infectious diseases or vaccines influences the development of the immune system of the newborn infant.
This is a Phase 2, randomized, multi-center study in approximately 300 adults who received 2 doses of aH5N1c or placebo in and completed the parent study V89_18 in the <65 years of age cohort. The study investigates whether two priming doses of MF59-adjuvanted H5N1 cell culture-derived vaccine (aH5N1c) followed by one or two booster vaccinations with a MF59-adjuvanted H5N6 cell culture derived vaccine (aH5N6c) 3 weeks apart elicit immune responses to the antigens used for priming (H5N1) and boosting (H5N6) after first and second heterologous booster vaccination. Eligible subjects, who received 2 doses of aH5N1c in the parent study V89_18 are randomized in a 1:1 ratio to receive either two aH5N6c vaccinations, 3 weeks apart (group 1) or an aH5N6c vaccination on Day 1 and saline placebo on Day 22 (group 2). Eligible subjects, who received placebo in the parent study will receive two aH5N6c vaccinations, 3 weeks apart (group 3). After the second vaccine administration, subjects are monitored for approximately 6 months for safety and antibody persistence. The total study duration will be approximately 7 months per subject.
This study is designed to test whether QBKPN SSI can improve immune function in older adults, including how well it can protect against respiratory and other infections, whether it improves the body's response to COVID-19 vaccines and what effect it has on maintaining or improving quality of life, activity level and health status. QBKPN is a new medication in a class known as Site-Specific Immunomodulators (SSI). SSIs are designed to train and/or improve innate immune function to reduce the risk of infections, improve immune response to cancer, and slow the progression of chronic inflammatory diseases. It is believed that QBKPN SSI can work with the immune system to help protect against respiratory and other infections.
The primary objective of this study is to determine the safety and efficacy profile of the food supplement (KUNAMIN®) containing grape juice, seed, stem, and bark given to patients treated with the established treatment regimen against novel coronavirus infectious disease (COVID-19) via comparing Kunamin® group versus control group in a clinical trial. In this study, both the therapeutic effect and the safety of the Kunamin® product has been evaluated. The study has been conducted on COVID-19 infected patients. Within the scope of the study, Covid-19 patients consisting of male and female patients are examined to evaluate the therapeutic effect. COVID-19 infected patients are divided into 2 groups and the treatment group received grape food supplements for 15 days in addition to their standard treatment. The other group received only standard therapy. The effects of supplements containing grape products on the COVID-19 infection process of patients are investigated, as indicated in the primary, secondary, and tertiary endpoints. For this purpose, both the observation of routine examination findings and the effectiveness of food supplements on viral load and antibody levels are investigated. In the follow-up that continues for 30 days, COVID-19 Rapid Antigen test made in USA approved by FDA is used to monitor the efficacy of Kunamin® as patient treated by Kunamin® viral load is diminished either after 5 days, 10 days or 15 days, COVID-19 Rapid Antibody test made in USA approved by FDA has been used to monitor the development of IgM and IgG antibodies on day 0, day 5th, day 10th, day 15th and day 30th in addition to PCR test of Perkinelmer by Kayseri hospital. In conjunction, the sponsor used AIT Laboratories A HealthTrackRx Company PCR test CLIA and FDA approved for not only COVID-19 but also 27 kinds of cold and flu viruses and 90 different kinds of bacteria. The number of patients planned for randomization was 240, however due to dropouts the hospital was able to screen 132 patients. Out of 132 patients we were able to enroll randomized total of 71 patients, 47 patients in the research arm and 24 in the control arm.
Thirty -one confirmed Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2 ) infected patients with Acute Respiratory Distress Syndrome (ARDS) and placed in prone position(PP) for 3 times (PP1, PP2, PP3)consecutively will be included. Arterial blood gases (ABG), partial pressure of arterial oxygen/ fraction of inspired oxygen (PaO2/FiO2 ) ratios, partial pressure of carbondioxide (PaCO2), positive end expiratory pressure (PEEP), and fraction of inspired oxygen (FiO2) values will be recorded before (bPP), during (dPP)and after (aPP) every prone positioning. Eye, skin, nerve and tube complications related to prone positions wll be recorded
The COVID-induced fibrotic lung damage continues long after viral infection has subsided and is exhibited by severe respiratory pathology and concomitant symptoms. The long-lasting sequelae in patients who have recovered from severe COVID indicate that there is a 30% chance of developing a persistent respiratory system pathology and a 10% chance of developing a severe pathology. The symptoms of lung fibrosis include a severe disruption of respiration, reduction of exercise tolerance, and concomitant development of persistent fibrotic lung damage. This study intends to evaluate benefits of a combination of VL-P22 and VL-PX10 in Covid-19 patients exhibiting pulmonary fibrosis.
Interferon gamma is a powerful endogenous regulatory cytokine that activates the antiviral immune response, while it also has its own antiviral activity. The objective of this study was to evaluate the effectiveness of the proposed treatment regimen with Ingaron (INN: recombinant interferon gamma human, lyophilisate for preparing a solution for intramuscular and subcutaneous administration of 500,000 IU) in patients with viral pneumonia.
