Food supplements like curcumin and boswellia serrata have been used traditionally for anti-inflammatory purposes. A well-known problem of these substances in their natural form is the low bioavailability. Micellization of these substances has been shown to increase the bioavailability significantly and thereby the clinical efficacy. The clinical value of these micellized substances has been presented in numerous clinical studies and in particular in patients with acute COVID-19. This study aims to examine the effect of a mixture of micellized curcumin, boswellia serrata and ascorbic acid on patients with long COVID.
To study the impact of COVID 19 infection on sleep habit as regards quality of sleep, emergence of insomnia. To assess quality of life in patients after COVID 19 infection.
Covid-19 pandemic has affected hundreds of millions globally(https ://coronavirus.jhu.edu/map.html), and hundreds of thousands in Egypt(https://www.care.gov.eg/EgyptCare/Index.aspx). However, the long-term consequences of the disease are still largely unknown. Data from 2002-2004 epidemics of SARS suggest that cardiovascular sequelae, such as microangiopathy, cardiomyopathy and impaired endothelial function, are to be expected also in COVID-19 patients.(Vittori et al, 2020) Hyperinflammation and immunosuppression are prominently featured in COVID-19, causing a cytokine storm leading to development of micro-thrombosisand disseminated intravascular coagulation (DIC). (Jose et al, 2020). These findings can be extremely relevant for male and female sexual health: indeed, based on these premises, there is quite enough evidence to hypothesize that consequences of COVID-19 can extend to sexual and reproductive health. (Sansone et al, 2020) A self-administered questionnaire will be disseminated using online electronic social network (Facebook, What's App) including: Sociodemographic age& gender. Sexual dysfunction will be assessed using International Index of Erectile Function-5 (IIEF-5) for males, and Arabic Female Sexual Function Index (ArFSFI) for females will be applied. Covid-19 related factors.
The coronavirus disease-2019 (COVID-19)is a pandemic disease caused by SARS -COV-2 which belongs to the β-coronavirus family . The majority of affected individuals exhibit no or mild to moderate symptoms, but up to 15% of patients develop severe pneumonia with approximately 6% progressing to acute respiratory distress syndrome and multiorgan failure. Biomarkers are needed to identify patients will suffer rapid disease progression to severe complications and death. Preliminary studies describe vasculitic processes underlying organ damage in seriously ill patients, induced by the activation of inflammatory cascades, complement activation and pro-inflammatory cytokines (i.e. interleukin). The severity of Vasculitic damage is unfortunately not easily predictable through currently used laboratory biomarkers such as D-dimer or prothrombin time/activated partial thromboplastin time. The severity of the disease is mainly driven by diffuse interstitial lung diseases. YKL-40 has a pro mitogenic action on pulmonary fibroblasts, increases the activity of macrophages and is associated with inflammatory disorders. In ILD, YKL-40 has been described to be associated with the severity of lung diseases and with the risk of death. YKL-40 serum levels could therefore be of interest for diagnosis and prognosis since it is at the cross-link between vascular and epithelial lung damage. .
The phase Ⅱ trial adopts a randomized, double-blind, placebo-controlled design to evaluate the immunogenicity and safety profile of LYB001 in healthy adults aged 18 years and older. This Phase III study adopts a single-arm, open-label design to evaluate the expanded safety of LYB001 in healthy subjects 18 years of age and older. The study vaccine will be administered IM at upper arm deltoid as a three-dose regimen with 28d interval on day 0, 28, 56. The phase Ⅱ trial will be carried out in an age-sequential enrolment manner: 1. A DSMB meeting will be held after the completion of the 7-day safety observation following each vaccination of high-dose LYB001 or placebo in participants aged 18-59 years in phase Ⅰ trial. Thereafter, the DSMB will recommend whether to initiate enrollment of younger adult participants in the Phase II trial based on the findings, who will receive low dose (25μg), high dose (50μg) LYB001 or placebo at a ratio of 3:3:1. 2. A DSMB meeting will be held after the completion of the 7-day safety observation following each vaccination of high-dose LYB001 or placebo in participants aged ≥60 year in phase Ⅰ trial. Thereafter, the DSMB will recommend whether to initiate enrollment of older adult participants in the Phase II trial based on the findings, who will receive low dose (25μg), high dose (50μg) LYB001 or placebo at a ratio of 3:3:1. 3. The phase Ⅱ trial will be ended after all participants completed 360-day safety observation following the 3rd dose of vaccination. Phase III trial (the expanded safety study): 1. After completion of the 7-day safety observation following the first immunization of all cohorts in the Phase II trial, a DSMB meeting will be held to recommend whether to initiate enrollment of participants in the Phase III trial. A total of 1200 subjects will be enrolled in younger adult and older adults, with older adults accounting for ≥20% of the population, and appropriate doses will be determined based on the results of early clinical trials. 2. The phase III trial will be ended after all participants completed 360-day safety observation following the 3rd dose of vaccination.
Context: Until 70% of thrombotic event are reported during Sars-CoV2 infection. Antiphospholipid antibodies (aPL) tests are often positive. We aim to determine if aPL positivity is involved in thrombose of Sars-CoV2 infection investigating the effect of aPL on thrombin generation (TG) and leucocyte pathway activation (neutrophils extracellular traps (NETs) and activation of triggering receptor expressed on myeloid cells 1 (TREM-1)). Method: We will compare plasma from five groups of subjects: patients with antiphospholipid syndrome (APS) and patients hospitalized for Sars-CoV-2 infection with or without aPL, and as control, patients with acute venous thromboembolism event and healthy volunteers. For each subject, we will analyze aPL, activated protein C (APC) resistance measured by TG and leukocytes markers as circulating neutrophils extracellular traps (NETs) and soluble triggering receptor expressed on myeloid cells one (sTREM-1). We will control aPL test at three month and analyze their persistent positivity and association with thrombotic event. Results: we hypothesize that patients with COVID-19 and aPL will have a similar aPL and level of APS resistance that patients with APS. Also, we think that circulating NETs and sTREM-1 levels will be more important in patients with COVID-19 with aPL than patients without aPL and similar in patients with COVID-19 and aPL and patients with APS. Conclusion: our study will be the first to analyze the potential role of aPL on APC resistance measured by TG and neutrophil activation in COVID-19.
This is a randomized, double-blind, placebo-controlled Phase Ⅰ trial in healthy adults aged 18 years and older, intended to evaluate the safety, reactogenicity, and immunogenicity profile of LYB001. The study vaccine will be administered IM at upper arm deltoid as a three-dose regimen with 28d interval on day 0, 28, 56. To ensure the safety of the participants, the phase Ⅰ trial was will be carried out in a dose-escalation and age-sequential enrolment manner: 1. The safety, reactogenicity, and immunogenicity will be firstly evaluated in a cohort of adults aged 18-59 years randomly assigned (4:1) either to receive low-dose (25µg) LYB001 or placebo. After confirmation of an favorable 7-day safety, reactogenicity profile in this cohort by investigator, the study was able to proceed to the cohort of adults aged 18-59 years receiving high-dose (50µg) LYB001 or placebo. 2. After completing a favorable 7-day safety observation following the first dose of 50μg LYB001 in cohorts aged 18-59 years, the study was able to advance to cohorts aged ≥ 60 years receiving low-dose (25µg) LYB001 or placebo. By analogy, all dose and age-stratified groups will be sequentially enrolled. The study will be ended after all participants completed 360-day safety observation following the 3rd dose of vaccination.
This study is the second cross-sectional study conducted in the region. In the first cross sectional study, conducted in the winter of 2020, we aimed to estimate the seroprevalence of SARS-CoV-2 IgG antibodies among blood donors in Sarajevo Canton. We also assessed immune durability among seropositive participants after 6 months. In total, of 1015 blood donors aged 18-65 years in Sarajevo Canton between 2 November and 3 December 2020 were recruited and population-weighted seroprevalence in Sarajevo Canton was 19.2% (95% CI: 16.7-21.6%). The aim of this second cross-sectional study is to measure the seroprevalence SARS-CoV-2 antibodies and assess antibody kinetics in the blood donor population after 12 months.
