Filter by:The gut immune system was shown as an effective target for inducing systemic immune signals against viruses. Oral administration of Travelan, an over the counter product which contains hyperimmune bovine colostrum was shown in preclinical studies to augment the anti-viral immune towards several strains of influenza viruses (RNA viruses). This study will evaluate the option that Trevalan may help improve the immune system reaction when introduced to COVID-19 proteins in-vitro. 5 healthy volunteers will receive a treatment regimen of 5 days with Trevalan. Before and after treatment, blood samples will be taken in order to test immune response towards viral proteins of the COVID-19 virus in vitro by measuring the number of T cell clone secreting IFNγ against viral antigens.
Coronavirus Disease-19 (COVID-19) is a global pandemics which affects many organs and systems with a range of morbidities and high mortality rates. There are a number of studies revealed that COVID-19 may affect the testes and male genital tract which may in turn disrupt the gonadal functions.The current study aimed to evaluate the effect of COVID-19 on semen parameters and sex-related hormone levels.
Chicken egg consists of three main components, egg white (56%), yolk (33%) and shell (11%). The key component of egg white is 88 percent water and 12 percent solids, of which over 90 percent are protein. Ovalbumin, ovotransferrin, and ovomucoid are considered the main proteins, while ovomucin, lysozyme, ovoglobulin, ovomacroglobulin, ovoglycoprotein, ovoflavoprotein, thiamin-binding proteins, ficin/papain inhibitors, avidin, and cystatin are the minor white proteins of the embryo. These proteins and their peptides have been recognized as antioxidants, antimicrobials, metal-chelators, anti-viral, anti-tumor, and angiotensin-converting enzyme (ACE)-inhibitors for their functional significance SARS-CoV-2 virus activates the human cell ACE2 receptor, triggering a series of deleterious events. In COVID19, renin-angiotensin is upregulated and the pathway is overexpressed and a progressive cytokine storm is always observed. In all these pathogenic processes, ovotransferrin could play a modifier function to enhance the condition. Ovotransferrin can be beneficial to the antioxidant effects of Angiotensin II by inhibiting NF-kB. Ovotransferrin is an immunomodulator that downregulates pro-inflammatory cytokines including TNF-α, IL-6, and IL-1 that could extinguish the cytokine storm. Ovotransferrin can also serve as a protective agent against COVID19 cardiotoxicity due to disruption in the ACE2-mediated signaling pathway, cytokine storm, pulmonary dysfunction, and side effects of medications. In patients with coronavirus infection, provided ovotransferrin's possible protective effects, it is suggested as a supportive and therapeutic alternative. Given this background, in the light of the current COVID-19 emergency, it is the intention of the investigators to conduct a prospective, randomized, open-label, controlled study in the cohort of hospitalized patients with covid-19 pneumonia, administering 200 mg of ovotransferrin orally in addition to the standard of care therapy (SOC). The investigators hypothesize that the use of ovotransferrin will be associated with an earlier improvement of clinical and humoral parameters after 10 days of ovotransferrin treatment when compared to the group of patients provided with standard care.
This is a randomized, placebo-controlled, double-blind, group comparison, multicenter study to evaluate the efficacy and safety of inhalation administration of sargramostim for 5 days, in principle (up to 10 days) as Add-on treatment to the standard treatment in COVID-19 patients.
Background: Invasive mechanical ventilation (IMV) in COVID-19 patients has been associated with a high mortality rate. In this context, the utility of tracheostomy has been questioned in this group of ill patients. This study aims to compare in-hospital mortality in COVID-19 patients with and without tracheostomy due to prolonged IMV Methods: Cohort study of adult COVID-19 patients subjected to prolonged IMV. Since the first COVID-19 case (March 3, 2020) up to November 30, 2020, all adult critical patients supported with IMV by 10 days or more at the Hospital Clínico Universidad de Chile will be included in the cohort. Pregnant women and non-adult patients will be excluded. Baseline characteristics, comorbidities, laboratory data, disease severity, and ventilatory support will be retrospectively collected from clinical records. The indication of tracheostomy, as part of our standard of care, will be indicated by a team of specialists in intensive care medicine, following national guidelines, and consented to by the patient's family. The 90-days mortality rate will be the primary outcome, whereas IMV days, hospital/CU length of stay, and the frequency of healthcare-associated infections will be the secondary outcomes. Also, a follow-up interview will be performed one year after a hospital discharged in order to assess the vital status and quality of life. The mortality of patients subjected to tracheostomy will be compared with the group of patients without tracheostomy by logistic regression models. Furthermore, propensity-score methods will be performed as a complementary analysis.
This is a Phase 2/3, randomized, placebo-controlled, multi-center trial to evaluate the safety, immunogenicity and efficacy of INO-4800 administered by intradermal (ID) injection followed by electroporation (EP) using CELLECTRA® 2000 device to prevent coronavirus disease 2019 (COVID-19) in participants at high risk of exposure to severe acute respiratory syndrome coronavirus - 2 (SARS-CoV-2). The Phase 2 segment will evaluate immunogenicity and safety in approximately 400 participants at two dose levels across three age groups. Safety and immunogenicity information from the Phase 2 segment will be used to determine the dose level for the Phase 3 efficacy segment of the study involving approximately 7116 participants.
Randomized, double-blind, placebo controlled clinical trial of immunogenicity, safety and efficacy of the Gam-COVID-Vac combined vector vaccine against the SARS-CoV-2-induced coronavirus infection in adults.

This Clinical Research aims to investigate the effectiveness of the treatment group and control group mortality rates, intensive care hospitalization times, monitoring the virus load by PCR, and the treatment effectiveness of UVC application. This Clinical Research covers determining the treatment effectiveness and reliability of UVC application to patient groups, the details of which are determined in the protocol.
Assessment of cause of Death in home Healthcare residents in Östergötland County, Sweden, who had a positive COVID-19 diagnosis and died between March and September 2020. Our aim is to evaluate the pattern of comorbidity and frailty in a group of individuals in home healthcare with positive COVID-19 diagnoses who had a fatal outcome, and a second aim is to assess the contribution of COVID-19 to those fatal outcomes.
The aim of the study is to investigate the efficacy of pulmonary rehabilitation (PR) program to patients with Sars-CoV-2 pneumonia in the post-acute period on pulmonary functions, exercise capacity and anxiety level. 100 patients diagnosed with Sars-CoV-2 pneumonia will be enrolled in this prospective, interventional study according to inclusion/exclusion criteria. Patients will be evaluated and a personalized PR program will be organized before hospital discharge. After discharge, the pulmonary rehabilitation program will continue in telerehabilitation. In the telerehabilitation program, exercises will be supervised by a physiotherapist two days a week, and patients will be asked to do the exercises themselves for the other 3 days. Patients will also receive exercise videos for these 3 days. Patients will be followed for 4 weeks and will be called for final evaluation
