The involvement of the kidneys in patients infected with the SARS-CoV-2 virus at the outset of the pandemic was associated with high mortality rates worldwide. This was in part due to the generation of an inflammatory process and exacerbated oxidative stress. The present study was initiated to investigate the relationship between morphofunctional changes and gene expression in the kidney tissue of deceased Mexican patients prior to the initiation of vaccination. The investigator designed a single-center, prospective, cohort study, to analyze and relate the morphofunctional changes and gene expression of inflammatory and oxidative stress molecules in the kidney tissue of men who died from severe COVID-19. A total of 40 percutaneous renal biopsies from deceased patients with SARS-CoV-2 infection were included in the study and divided into two a groups. One group was preserved in trizol to obtain RNA and total protein, while the remaining sample was fixed in formalin to be examined by staining with hematoxylin and eosin. The histopathological analysis was conducted by an experienced nephropathologist. The expression of molecules was evaluated by real-time PCR (nphs2, slc9a1, cx3cl1, havcr1, slc22a17, sod2, egf, timp2, hmox1, fabp1, and so forth). The following biomarkers were analyzed: IL-6, Arg-1, DPP4, GSTT1, GGT1, OCL, CYP3A4, and CL-8. Additionally, Western blot analysis was conducted on claudins-5, occludin, HSP70, NRF-2, SOD2, NQO1, γ-GCL, and RAGE. The estimated glomerular filtration rate (eGFR) was calculated using the CKD-EPI (2021) equation, with the subjects divided into two groups based on their eGFR: >60 or <60 ml/min/1.73 m². The statistical analysis was conducted using the Stata program and GraphPad Prism software.
A clinical trial to evaluate the safety, reactogenicity, and immunogenicity of MPV/S-2P administered intranasally to adults who have previously received a primary series and at least one booster with an authorized or licensed mRNA SARS-CoV-2 parenteral vaccine. The primary objective is to evaluate the safety and reactogenicity of a single dose of MPV/S-2P in previously vaccinated healthy adults.
We are conducting a study on alternative treatments for patients who have received an current or previous positive COVID-19 diagnosis with mild-serve symptoms or undiagnosable condition after testing positive for severe acute COVID-19 infection and are experiencing long-haul symptoms. The symptoms of long COVID can include extreme tiredness (fatigue), shortness of breath, memory and concentration issues (brain fog), heart palpitations, dizziness, joint pain, muscle aches, cough, headaches, anxiety, and depression. It's important to note that there are various other symptoms that individuals can experience after a COVID-19 infection, such as loss of smell, chest pain or tightness, difficulty sleeping (insomnia), pins and needles, depression, anxiety, tinnitus, earaches, nausea, diarrhea, stomach aches, loss of appetite, cough, headaches, sore throat, and changes to the sense of smell or taste. To be included in the study, participants must have had symptoms for more than 4 weeks. The goal of the study is to measure biomarkers, identify new ones through clinical trials, and individualize and optimize treatment plans, which may or may not include COVID-19 post-market antivirals, vaccines, and medical care. It's essential to conduct thorough clinical trials to understand the long-term effects of COVID-19 and to develop personalized treatment plans for individuals experiencing long-haul symptoms.
The aim of this study is to evaluate whether there are chronic effects in the pulmonary system and systemic level in individuals in the post COVID19 period in order to elucidate the involvement of inflammation after recovery. In addition, a perspective on the utility of pulmonary function testing and pulmonary ultrasound in the evaluation of chronic effects and patient follow-up will is aimed to be provided. By measuring the protein levels of inflammatory markers along with the data abovementioned, a foresight regarding the long-term effects of the previous infection at both functional and immunological levels will be obtained, allowing us to evaluate the post-COVID period from different angles. Volunteers who recovered from COVID-19 and those who didn't have COVID-19 were compared by evaluating chest x-ray scores (CXR), lung ultrasound scores (LUSS), pulmonary function tests and inflammatory cytokine levels (TNF-α, IL-1, IL-6, IL-17A).
The primary objective of this study is to evaluate the safety and efficacy of Xiflam versus Placebo in patients who present with signs and symptoms of Long COVID. Xiflam (n=10) or placebo (n=5) will be administered orally once a day (QD) for 12 weeks.
Reports of long-lasting symptoms of COVID-19 are increasing, but little is known about the prevalence of risk factors or whether it is possible to predict a prolonged course at disease onset. Prolonged COVID is characterized on the basis of symptoms such as fatigue, headache, dyspnea, and anosmia present for weeks, with older age, high body mass index, and female sex being more susceptible. Accordingly, and in the absence of specific treatments, the present study seeks to establish a treatment protocol for Post-COVID syndrome through the application of the dietary supplement VIUSID, due to its anti-inflammatory and immunomodulatory effect, thus helping to reduce and/or control the symptoms of the syndrome.
Currently, several vaccines are available to combat the COVID-19 pandemic. The persistence of SARS-CoV-2 globally requires the development of additional vaccines to aid in preventing further SARS-CoV-2 infections. Covigenix VAX-002 is a vaccine based off its predecessors VAX-001 and VAX-001-1b. All three are plasmid DNA vaccines that express key antigenic determinants from SARS-CoV-2 and use the Entos Pharmaceuticals' Fusogenix proteo-lipid vehicle (PLV) platform. Currently, the safety and tolerability of VAX-001 and VAX-001-1b for primary vaccination following 1 or 2 doses are being investigated in a Phase 1/2 study (ENTVAX01-101). In Phase 1, VAX-001 was administered to healthy adults on Day 0 and Day 14, as either 2 low doses (100 μg/dose) or 2 high doses (250 μg/dose). Overall, data suggest that VAX-001 is safe at both the low and high dose levels. The Phase 2 part evaluates VAX-001-1b in adults at a 100 μg dose level on a 1-dose and a 2-dose schedule (Days 0 and 28). An interim analysis conducted on data from 18 participants in the sentinel group who had received their first dose of 100 μg showed that VAX-001-1b was overall safe with minor adverse events (AEs) registered. No serious adverse events (SAEs) were reported. After a review of the data, the Data Safety Monitoring Committee (DSMC) provided their recommendations for the participants in the 100 μg dose sentinel group to receive a second dose. The present study investigates the safety and immunogenicity of VAX-002 when given as a booster dose to generally healthy adults aged 18 years or older who have received a primary vaccination course or a booster dose of an authorized COVID-19 vaccine at least 3 months prior to Day 0. VAX-002 was specifically designed to address the new circulating omicron variants of SARS-CoV-2. The study consists of 2 parts: a dose-finding/safety evaluation part (Phase 1) to determine the dose of VAX-002 for booster vaccination (100 μg or 250 μg) followed by an adaptive Phase
In this study we aim to characterize SARS CoV-2 strain specific immune response (SARS-CoV-2 Spike IgG) in health care workers and general populations at the Jimma Medical Center and the St. Paul Hospital in Addis Ababa in association to clinical immune protection and Covid-19 disease. Participants, stratified by SARS-CoV-2 infection and vaccination status, will be followed at 3-month intervals for a maximum of 2 years. Prevalence, incidence, and dynamics of SARS-CoV-2 specific antibodies as well as clinical assessments especially related to COVID-19 breakthrough disease in previously exposed/vaccinated participants will be performed. From a subset of selected participant blood sample, more in depth immunological analysis will be performed that include virus culture-based neutralization assays, antibody avidity assays, SARS-CoV-2 specific antibody epitope recognition using peptide arrays, and T-cell immunity assays (IGRA). We also plan to analyze and model cost-effectiveness considerations related to adapted COVID-19 vaccine strategies, specifically if SARS-CoV-2 the costs for routine sero-diagnosis in high SARS-CoV-2 prevalent population prior to vaccination will impact the decision to vaccinate (no vaccination for low-risk populations or reduced vaccine dosing) and is cost-efficient. The study is largely exploratory, providing deeper insights in SARS-CoV-2 specific immune responses and interaction with SARS-CoV-2 viral variants.
The purpose of this study is to compare oral hygiene status and dietary habits of 3-5 years old children and their parents with a questionnaire and clinic examination between pre- and post-COVID-19 period.
