Filter by:Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of the Coronavirus disease (COVID-19). Tuberculosis (TB) is the foremost cause of infectious deaths globally. In 2025, an additional 1.4 million TB deaths could occur as direct consequence of the COVID-19 pandemic. It is postulated that individuals with latent or active TB are more susceptible to SARS-CoV-2 disease and that COVID-19 disease rate is high in patients with active TB, although the evidence is still scarce. TB and SARS-CoV-2 are both infectious diseases which primarily attack the alveolar region of the lungs and share common symptoms. SARS-CoV-2 disease can induce innate and adaptive immunity, but uncontrolled inflammatory innate immunity and impaired adaptive immune responses may be associated with severe tissue damage, both locally and systemically. People with coinfection (COVID-19 and TB disease) might potentially have impaired protective immune responses and treatment outcomes, specifically as far as anti-tuberculosis treatment is concerned. However, very little is known about the immunological underpinnings in this interface between TB and COVID-19 on the effect of SARS-CoV-2 disease on disease severity, response to treatment and treatment outcomes in pulmonary tuberculosis. Investigators hypothesize that altered immunity due to prior or present asymptomatic disease with SARS-CoV-2 virus can lead to altered immune responses and systems biology, increased severity and altered treatment outcomes in TB disease. The main objective of the study would be to evaluate the baseline differences in immune cells populations immune cell responses at baseline and at the time of treatment (2nd month) and end of treatment. Further, Investigators would be evaluating the changes in proteomic profiles in a subset of these individuals. In addition, immunological assays examining differences in T cell populations, measuring levels of various cytokines and by immunophenotyping as well as other immune parameters related to innate and adaptive responses will be performed to enhance the understanding of the immunological cross-talk between active TB patients with or without SARS-CoV-2. The secondary objective would be to study the clinical features, disease severity, mycobacterial burden and treatment outcomes in a cohort of SARS-CoV-2 infected (asymptomatic PCR or Antibody+) and non-infected patients with active pulmonary TB.
The purpose of the study is to assess the effectiveness of the HALT COVID Ambassador educational outreach program on increasing likelihood to vaccinate against COVID-19
This study aims to assess cerebral autoregulation by near-infrared spectroscopy (NIRS) in patients with severe coronavirus disease 19 (COVID-19). Results on COVID-19 participants will be compared with prior results of patients with septic shock and cardiac arrest, who participated in NCT03649633 and NCT02790788, respectively.
This is an open-label study to evaluate the safety and preliminary efficacy of Codivir in 12 mild or moderate COVID-19 patients and onset of symptoms within 72h prior to their inclusion. Treatment will begin in the hospital, participants will be discharged at Day 4 and continue the treatment up to Day 10 at home and followed up to day 28.
The objective will be to analyze the development of cellular and humoral immunity against SARS-CoV-2 after administration of a third dose of mRNA-1273 (Moderna) vaccine in patients who have remained seronegative after the full standard (two-dose) regimen.
The main objective is to quantify the population of reverse migrating neutrophils in patients with COVID-19.
1. assessment of risk factor of covid 19 in haematological patients 2. assessment of characteristics of covid 19 in haematological patients
The TRANSCOV cohort is a multicentre observational retrospective study aiming at assessing the health impact of extra regional transfers of critically ill COVID-19 patients.
Randomized, Blind, Placebo-controlled Phase- I Study and Randomized, Open Phase Phase-II Study of QazCoVac-P - COVID-19 Subunit Vaccine in Healthy Adult Volunteers From 18 Years Old and Elder
The objective was to find out the impact of COVID-19 on stage of breast cancer at presentation and its effects on overall onco-surgical management. The investigator carried out this research to see the presenting stage of breast cancer in the participants in this pandemic and correlate its effect on stage of breast cancer and upstaging of disease
