Filter by:The aim of the cohort prospective observational study is to define the major factors influencing the course of COVID-19 infections and its prognosis in hospitalised patients. The investigators plan to include 300 patients hospitalised with COVID-19 infection. The phone contacts with patients are due after 90 and 180 days after discharge.
prospective multicenter study The main aim is to study the impact of maternal COVID-19 vaccination on breast milk immune, microbiological, and metabolic profile.
A double-blind, placebo-controlled, randomized clinical trial to assess efficacy of micronutrient dietary supplementation in reducing hospital admissions for COVID-19 and incidence of Long Covid. We want to assess the need for hospital admission for severe acute respiratory syndrome Corona Virus-2 (SARS-CoV-2) infection in outpatients diagnosed of COVID-19 disease, taking a micronutrient supplementation for 14 days. The outcome Will be measured within 1 month after beginning the study treatment. The patients will be followed-up for a period of 180 days for the incidence of Long Covid
Coronavirus disease (COVID-19) has resulted in millions of hospital admissions. The physical consequences caused by COVID-19 hospitalization could jeopardize the overall health status of patients through a decrease in functional capacity. A therapeutic exercise program may reduce the adverse effects of COVID-19 on functional capacity and thereby improve the overall health status of these patients. The objectives of this project are 1) to analyze the effect of a therapeutic exercise program in patients who have been hospitalized in Intensive Care Unit (ICU) for COVID-19. Single-blind randomized clinical trial. 118 patients post-ICU for COVID-19 will be randomized into an intervention group and a control group. The intervention group will perform a therapeutic exercise program for eight weeks in telematic modality. Functional capacity will be analyzed using the grip strength, Short Physical Performance Battery, gait speed, lower extremity strength and the FRAIL scale at baseline, eight and twelve weeks. The main statistical analysis will be a comparison of means for independent samples assessing the effect of the intervention. Given the high prevalence of patients hospitalized for COVID-19, establishing strategies to minimize the adverse effects of the virus on patients is a must for the healthcare setting. Assessing physical condition after COVID-19 will allow the magnitude of the problem to be established. Physiotherapy, through therapeutic exercise, could improve physical fitness in these patients and thus improve the overall health status after COVID-19.
Based on the literature, it seems likely that a nutritional intervention with nicotinamide (a form of vitamin B3) can support the therapy of SARS-CoV-2 infection (COVID-19). A pilot phase of the COVit trial showed an effect of nicotinamide on the time to complete resolution of COVID-19 symptoms. In addition, diarrhoea is a common symptom of COVID-19. Therefore, in a second part of the study, 420 symptomatic patients each with confirmed SARS-CoV-2 infection are to take 1,000 mg nicotinamide (500 mg conventional nicotinamide and 500 mg nicotinamide released in a controlled manner in the intestine) or corresponding placebos per day in a blinded fashion for 4 weeks. The primary endpoint of the trial is the occurrence of individual COVID-19 symptoms over time (primary analysis time point: week 2). Secondary endpoints focus on the severity of COVID-19 symptoms, the post-COVID-19 syndrome (PCS), anti-SARS-CoV-2 antibody levels, and the time to resolution of individual or all symptoms. Exploratory endpoints include the WHO clinical scale for COVID-19, development of severe COVID-19, fatigue, quality of life and biomarkers. Patients are approached after positive testing and give their informed consent online. After randomised distribution of the trial supplements, patients are interviewed by telephone about their disease course at baseline (week 0), week 2, week 4, week 6 and after 6 months. Stool samples are collected from up to 400 patients at the same timepoints. In addition to blood count and standard blood profile, various inflammatory markers and the metabolome, in particular tryptophan metabolism, are examined in the blood of up to 20 selected patients. In these patients, the viral strain is determined by sequencing from nasopharyngeal swabs. In selected patients, short-term pharmacokinetics of nicotinamide, nicotinic acid and nicotinuric acid as well as of metabolites of nicotinamide and tryptophan are investigated. In the stool, changes in the microbiome (in 100-300 patients) as well as metagenome and metabolome (in a subgroup) will be analysed. The study is expected to produce rapid results on whether nicotinamide supplementation can alleviate the disease course of COVID-19. Moreover, a follow-up interview, a smell test, a cognitive test and anti-SARS-CoV-2 antibody levels after at least 6 months will be used to investigate whether the supplementation has any influence on PCS as well as the immune reaction against SARS-CoV-2.
It has been well documented that patients in the intensive care unit (ICU) are susceptible to developing neurocognitive and musculoskeletal complications because of various factors, including the nature of the critical illness, medications, over-sedation, and pain. Neuro-stimulants are used to speed up physical and mental processes through the increase in neurotransmitter, which translates into increase in arousal, wakefulness, attention, memory, mental and motor processing speed. The investigators reviewed the literature and described the clinical characteristics for a case series of adult patients admitted to COVID and non-COVID ICU between January 2017 and June 2020, who received modafinil to promote wakefulness and improve cognition at the King Faisal Specialist Hospital and Research Centre (KFSH&RC) in Riyadh, Saudi Arabia. The secondary goals to describe the change of Glasgow Coma Scale (GCS) before and after the start of modafinil therapy, ICU and hospital length of stay, discharge disposition, adverse drug effects, and mortality rate.
The main objective of the study is to describe the temporal curve of COVID-19 IgG and neutralizing antibodies over 24 months in an identified population of patients who presented with SARS-CoV-2 virus infection. The secondary objectives are to characterize the kinetics of the antibodies according to the severity of the clinical presentation and patient's characteristics and to determine if the anti-SARS-CoV-2 antibodies retain their neutralizing capacity over time. A sub-study aims to describe the kinetic of neutralizing antibodies (in blood and nasal mucosa) after vaccination.
Prospective study that will evaluate the clinical agreement of the CoviDx™ Rapid Antigen test compared to SARS-CoV-2 RT-PCR.
This study is to evaluate of the accuracy of biomarkers (i.e. circulating endothelial and immune activation markers) that indicate progression to severe disease in patients with suspected COVID-19 in the Emergency Department. It is a prospective observational study of patients presenting to emergency departments with a clinical suspicion of COVID19. All participants will have plasma samples collected for biomarker analysis, and will be tested for SARS-CoV-2 infection with a nasopharyngeal swab. Participants will be managed according to the best local practices.
In December 2019, the first people got infected with COVID-19 in Wuhan, China. Within weeks, this highly infectious disease spread all over the world. Nearly one year later everyone is still trying to battle this disease and facing the consequences it causes. What became clear is that the disease and its severity differs largely between infected people. However, knowledge about who will experience severe COVID-19 and who does not is still unclear. Therefore, the aim of this study is to investigate the prognostic value of certain parameters (mtDNA and CT radiomics signature) for the severity of COVID-19.
