Filter by:There were many studies in the literature discussing the effects of vitamin D deficiency and the role of vitamin D supplementation in SARS-CoV-2 patients. Combined with the possible impact of vitamin D on the pathogenesis of SARS-CoV-2 infection, it is concluded that VDBP-regulated bioavailable and free vitamin D concentrations modulate the human immune system response to viral infections. Because of the gap in the literature, it was emphasized that studies should focus on vitamin D binding protein (VDBP) and gene polymorphism. In this study, it was aimed to investigate the relationship between SARS-CoV-2 infection severity and free and bioavailable vitamin D levels.
Study type: Phase 2 - Interventional Trial Number of patients to be enrolled: 105 Participating countries: Italy Study drugs: nivolumab and ipilimumab Cohort A: HBV and HCV patients Cohort B: HIV patients Cohort C: Long COVID syndrome The stratification factors are HBV/HCV positive (cohort A), HIV positive (cohort B), patients with Long Covid syndrome (Cohort C), histology (squamous vs non-squamous histology), and gender (male vs female).
The main objective of the present study is to observe the short-term effects of respiratory muscle training combined with an exercise training program on quality of life and exercise tolerance in individuals with long-term post-COVID-19 symptoms. As secondary objectives, the effects on respiratory muscle function, physical and lung function, as well as on the psychological state of these individuals.
This multicenter, prospective, non-interventional cohort study aims to evaluate data on humoral and cellular immune response generated within the COVID-19 vaccination standard in patients with B-cell non-Hodgkin lymphoma (NHL) or Hodgkin lymphoma (HL) who underwent autologous hematopoietic stem cell transplantation (HSCT) or who were treated with or chimeric-antigen-receptor-T-cells (CAR-T).
This study will assess two options to help patients better manage the cognitive fog and emotional distress that may be associated with having Long-COVID. Long-COVID is post-COVID conditions or symptoms lasting more than four weeks after infection. Clinicians from the UPMC Long-COVID Clinic leading this study are evaluating the utility of computer-based evaluation of COVID-related cognitive fog and the helpfulness of two intervention strategies to treat moderate cognitive impairment using a randomized trial. The two intervention strategies include 1) a standardized dosing of amphetamine/dextroamphetamine medication that has been used to improve cognitive fog; and 2) a digital behavioral tool with an embedded health coach that is used on a mobile phone.
Substudy A: This is a Phase 1 randomized, open-label study to describe the safety and immunogenicity of up to 3 dose- level combinations of modRNA quadrivalent influenza vaccine (qIRV (22/23)) and bivalent BNT162b2 (original/Omi BA.4/BA.5). Participants will receive either: - qIRV (22/23)/bivalent BNT162b2 (original/Omi BA.4/BA.5), at 1 of the 3 dose-level combinations - qIRV (22/23) at dose level 1, - qIRV (22/23) at dose level 2, or - bivalent BNT162b2 (original/Omi BA.4/BA.5) at dose level 1 administered concurrently in the opposite arm to commercially licensed quadrivalent influenza vaccine (QIV). Substudy B: This Phase 1/2 study will describe the safety, tolerability, and immunogenicity of quadrivalent influenza vaccine (qIRV)/bivalent BNT162b2 (original/Omi BA.4/BA.5), trivalent influenza vaccine (tIRV)/bivalent BNT162b2 (original/Omi BA.4/BA.5), and bivalent influenza vaccine (bIRV)/bivalent BNT162b2 (original/Omi BA.4/BA.5) when given concurrently with licensed quadrivalent influenza vaccine (QIV).
We performed a quasi-experimental open-label pragmatic study alternating standard of care (SOC) and oral bedtime melatonin (OBM) at different high doses over 4 consecutive time periods enrolling all consecutive RT-PCR SARS-CoV-2 severe Covid-19 admissions.
This is a phase Ib, randomized, double-blind, placebo-controlled study to evaluate safety, tolerability, efficacy and pharmacokinetics of ASC10 tablets in mild or moderate COVID-19 subjects.
The purpose of the study is to conduct a prospective evaluation of the diagnostic performance of the IVD CAPSULE COVID-19-NP test for antigenic determination of SARS-CoV-2 virus on the abioSCOPE® instrument. The objective of the clinical study is to demonstrate that the IVD CAPSULE COVID-19-NP test: 1. shows sensitivity: - ≥ 80% when testing unselected symptomatic participants within the first seven days of symptom onset or asymptomatic participants when diagnosis is confirmed by RT-PCR; Or - ≥ 90% for subjects with Ct ≤ 25. 2. show ≥ 98% specificity.
The purpose of this study is to collect data generated by standard clinical practice to determine the short term and long term clinical outcomes of recipients of solid organ transplantation from COVID-19 infected donors and compare it to recipients with organ transplant from COVID-19 negative donors.
