NCT ID: NCT05226377 Completed - COVID-19 Clinical Trials

Relation Between Atherogenic Index of COVID-19 and Upcoming Cardiac Morbidity and Mortality in Non-Cardiac Patients

Start date: March 7, 2021
Phase:
Study type: Observational

Plasma lipids levels were estimated and the Atherogenic Index of Plasma (AIP) was computed in 302 COVID confirmed patients. Patients were evaluated using the COVID-GRAM (CG) critical illness score and during a hospital stay the rates of admission to intensive care unit (ICU), development of cardiac insults, and need for admission to cardiac ICU (CCU) and its outcome were determined.

NCT ID: NCT05225285 Recruiting - COVID-19 Clinical Trials

Curumim
Start date: January 21, 2022
Phase: Phase 3
Study type: Interventional

To evaluate the efficacy and safety of vaccinating children and adolescents, aged 3 to 17 years, with a two-dose schedule of the inactivated vaccine (Coronavac) against SARS-Cov-2.

NCT ID: NCT05225220 Completed - Clinical trials for Cognitive Dysfunction

Multimodal Investigation of Post COVID-19 in Females

Start date: March 1, 2022
Phase: N/A
Study type: Interventional

The purpose of this study is to investigate the effects of transcutaneous vagus nerve stimulation (t-VNS) on Long Covid symptoms in females and to identify factors influencing susceptibility and recovery-particularly in the cognitive domain, as over 80% of long-haulers experience "brain fog".

NCT ID: NCT05225194 Not yet recruiting - COVID-19 Clinical Trials

Long-term Impact of COVID-19 Among COVID-19 Patients With Acute Respiratory Distress Syndrome in Brazil

Start date: February 15, 2022
Phase:
Study type: Observational

The present multicenter prospective observational study aims to assess the long-term effects of COVID-19 on patients with Acute Respiratory Distress Syndrome (ARDS). This is a hybrid design study with components of cohort and case-control designs. Survivors of hospitalization due to ARDS caused by SARS-CoV-2, survivors of hospitalization due to ARDS caused by other etiologies not associated with SARS-CoV-2, and family controls without history of COVID-19 or hospitalization will be followed up for a period of 6 months.

NCT ID: NCT05225064 Completed - Vaccination Refusal Clinical Trials

Increasing COVID-19 Vaccine Uptake in Developing Countries (Bihar)

Start date: January 19, 2022
Phase: N/A
Study type: Interventional

Working with governments in Bihar, India, we will evaluate a number of mechanisms to increase vaccine uptake. These include household vaccination visits instead of community vaccination clinic.monetary and non-monetary incentives, and concurrent mask promotion. This ClinicalTrials entry contains results only for the study in Bihar.

NCT ID: NCT05224856 Withdrawn - COVID-19 Clinical Trials

To Evaluate the Safety and Efficacy of Inhaled CT-P63 and CT-P66 Combination Therapy in Symptomatic Patients With COVID-19 Not Requiring Supplemental Oxygen

Start date: April 2022
Phase: Phase 3
Study type: Interventional

This is a Phase 3 study to assess the efficacy about therapeutic effect of inhaled CT-P63 and CT-P66 combination therapy to symptomatic patiemts with COVID-19 and overall safety.

NCT ID: NCT05224830 Completed - COVID-19 Clinical Trials

Relationship Between Hyperventilation Syndrome and SARS-CoV-2 Infection

Hypercovid
Start date: January 1, 2021
Phase:
Study type: Observational

Following an acute COVID-19 infection, many patients suffer from long lasting physical symptoms that may greatly impair quality of life. Persisting dyspnea and other functional respiratory complaints could evoke Hyperventilation Syndrome (HVS) as a putative contributor of the long-COVID presentation in COVID-19 survivors. We aimed to assess the possible relationship between a HVS and previous acute SARS-CoV-2 infection.

NCT ID: NCT05224622 Completed - COVID-19 Clinical Trials

Detection of COVID-19 Using Breath Analysis - Validation Study.

Start date: January 18, 2022
Phase: N/A
Study type: Interventional

Detection of the 2019 novel Coronavirus (SARS-CoV-2) using breath analysis - Validation study.

NCT ID: NCT05224388 Completed - COVID-19 Clinical Trials

Evaluating Dose Regimen of Intravenous Unfractionated Heparin and Low Molecular Weight Heparin in Critical Ill Patients Versus Critical Ill COVID-19 Patients Using Anti-Xa Levels.

Start date: January 1, 2020
Phase:
Study type: Observational

To see whether our increased dosing regimen of unfractionated heparin (UF) and low molecular weight heparin (LMWH) in COVID-19 patients was effective at preventing thrombo-embolic complications. We did regular anti-Xa tests to optimise the dose of our thromboprophylaxis. Furthermore, we want to examine the time it takes to reach adequate anti-Xa levels, to determine additional risk factors and do a subgroup analysis. Lastly, we will study if there are possible complications of our thromboprophylactic therapy.

NCT ID: NCT05222750 Completed - COVID-19 Clinical Trials

Epidemiology of Thrombotic Thrombocytopenia Syndrome in Integrated Health-care Database in England

Start date: March 1, 2022
Phase:
Study type: Observational

Background/Rationale: A rare syndrome of thrombosis associated with low platelets has been reported in a few cases of recent exposure to COVID-19 vaccine. Medicines & Healthcare products Regulatory Agency (MHRA) had requested for all cases of thrombosis or thrombocytopenia occurring within 28 days of coronavirus vaccine to be reported via the online yellow card system. This syndrome seems to be affecting patients of all ages and both genders; at present there is no clear signal of risk factors. Up to and including 14 April 2021, the MHRA had received 168 United Kingdom (UK) reports of thrombo-embolic events with concurrent low levels of platelets following the use of the COVID-19 Vaccine AstraZeneca. The United Kingdom (UK) is uniquely placed to study this area because of its registration-based primary care system, and a unique identifier number links primary care to secondary care data. Additionally, vaccination is well advanced, maximising population wide vaccine exposure. Objectives and Hypotheses: Estimate event rates and describe characteristics of patients with a record for thrombotic thrombocytopenia syndrome, thromboembolism or thrombocytopenia, in the general population of England. Methods: Study design: Secondary data analysis using a cohort design. Data Source(s): This is a retrospective cohort study using linked secondary databases in England accessed through the NHS Digital Trusted Research Environment (TRE). The primary care data will be linked with vaccination, primary care data, hospitalization, COVID-19 test results, mortality data at the national level for capture of key study variables. This integrated digital health system will also include other linkages such as the Oxford-Royal College of General Practitioners sentinel network; ORCHID. Study Population: All patients, with our population of interest in England who are present in the integrated health records of NHS Digital TRE and/or the Oxford Royal College of General Practitioners Clinical Informatics Digital Hub (ORCHID) database at the start of each study period. Variables: Demographic, socioeconomic, clinical descriptors and risk factors for thrombosis and/or thrombocytopenia; COVID-19 vaccines. Statistical Analysis: The event rates with 95% CIs will be calculated by dividing the number of events with person-time at risk per 100,000 person-years. Further, event count and event rates will be evaluated in a relationship with COVID-19 vaccination date.
