NCT ID: NCT04930978 Recruiting - Clinical trials for COVID-19 Respiratory Infection

Effect of SARS-CoV-2 Disease on Immune Responses, Disease Severity and Treatment Outcomes in Pulmonary Tuberculosis

COVID-19-TB
Start date: June 21, 2021
Phase:
Study type: Observational

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.

NCT ID: NCT04930965 Completed - Covid19 Clinical Trials

Impact of LA-CEAL HALT COVID-19 Ambassador Program on Likelihood to Vaccinate

Start date: October 5, 2021
Phase: N/A
Study type: Interventional

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

NCT ID: NCT04930874 Recruiting - COVID-19 Pneumonia Clinical Trials

Cerebral Autoregulation and COVID-19

CA-COVID
Start date: June 22, 2021
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT04930861 Completed - Covid19 Clinical Trials

Study of Codivir in Patients With COVID-19

Codivir
Start date: March 29, 2021
Phase: Phase 1
Study type: Interventional

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.

NCT ID: NCT04930770 Withdrawn - Covid19 Clinical Trials

Study About the Response to the Administration of a Third Dose of mRNA-1273 Vaccine (COVID-19 Vaccine Moderna) in Renal Transplants With Immunological Failure Initial to Vaccination

VAX-TRES
Start date: August 1, 2021
Phase: Phase 2
Study type: Interventional

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.
