The recent inception of the coronavirus SARS-CoV-2, responsible for the coronavirus disease (COVID-19), has caused thousands of deaths globally. The most frequently reported complications among COVID-19 patients are from respiratory involvement. Vitamin D has immunomodulatory effects that could protect against COVID-19 infection. Indeed, there is good evidence from randomized clinical trials suggesting that high doses of vitamin D administered during cold seasons prevent viral respiratory infections in at risk individual, and more recently, observational studies suggested that the mortality rate from COVID-19 is inversely correlated with levels of serum 25(OH)vitamin D. The hypothesis of the study is that a high dose of vitamin D given orally to patients admitted to the hospital for COVID-19 will prevent the occurrence of respiratory deragement and other adverse clinical events. To evaluate the aforementioned hypothesis, a randomized, controlled, double-blind, clinical trial comparing a 500.000 UI dose of vitamin D versus placebo among COVID-19 patients at moderate risk, requiring hospitalization but without requirements of critical care at admission was designed. The intervention will be one dose of 500.000 UI given orally or matching placebo. The trial has a sequential design with two steps: - The first step, projected to include 200 patients, will assess the effects of the intervention on the respiratory SOFA; and - If there is a detectable effects, the second step, projected to include 1264 patients, will assess the effects on a combined event that includes need of high dose of oxygen or mechanical ventilation. All study outcomes will be measured during the index hospitalization.
This is an open-label, multicenter, parallel-group, randomized, phase III trial that evaluates the efficacy and safety of hydroxychloroquine and favipiravir in the treatment of patients with possible or confirmed COVID-19 observed within the last 5 days. 1000 patients will be randomized in 2:1:2:2:2:1 ratio and divided into six groups.
Background: COVID-19 is a disease caused by the SARS-CoV-2 virus. It infects the respiratory tract. Some people who get COVID-19 have only mild symptoms. But for others, infection leads to pneumonia, respiratory failure, and, in some cases, death. Researchers want to learn more about any effects that may persist after people recover from COVID-19. Objective: To learn about any long-term medical problems that people who have recovered from COVID-19 might have, and whether they develop an immune response to SARS-CoV-2 that provides protection against reinfection. Eligibility: People age 18 and older who have recovered from documented COVID-19 or were in close contact with someone who had COVID-19 but did not get the infection Design: Participants will be screened over 2 visits. During visit 1, they will answer questions about any symptoms they are having and will be tested for SARS-CoV-2 infection which will involve a nasal swab sample or other FDA approved test. If the test is negative, they will proceed to the second visit, which will include: Physical examination Medical history Mental health interview (which may be recorded if the participant agrees) Chest x-ray (for recovered COVID-19 participants only) Blood and urine tests Pregnancy test (if needed) Lung function test (for recovered COVID-19 participants only) 6-minute walk test (for recovered COVID-19 participants only) Questionnaires about their general and mental health Leukapheresis to collect white blood cells (optional). Participants will be put into 1 of 2 groups: the COVID-19 group or the close contact group. Participants will have study visits every 6 months for 3 years. They will repeat some of the screening tests. Participants in the COVID-19 group may have visits more often if they develop symptoms that suggest re-infection with SARS-CoV-2....
In order to prevent contamination from the pregnant women hospitalized in this clinic, the RT-PCR test is performed from the oropharyngeal and nasal swab sample taken before hospitalization. In addition, the same test is done before each operation and before the operation. The aim of the study is to scan these tests retrospectively and to determine the rate of positive COVID-19 cases in asymptomatic pregnant women. The results will determine the importance of the measures to be taken in the pregnant women who undergo intervention.
The study design is observational, exploratory study consisting of two cohorts of COVID-19 patients admitted to the ICU and the medical ward, respectively. The primary outcome focusing on the effect of plasma glucose levels on cardiac function will be evaluated by repeated assessment of cardiac function by echocardiography and measurement of plasma glucose. Furthermore, blood coagulability will be evaluated to determine the importance of diabetes status and plasma glucose changes for whole blood coagulability at time of admission to the ICU and progression in coagulability abnormalities. In the medical ward cohort, two assessments will be performed separated by no more than 12 hours. In the ICU cohort, three assessments will be performed separated by no more than 6 hours. Ideally, 60 patients with COVID-19 will be included in the ICU cohort with a 1:1 distribution between patient with and without diabetes. Ideally, 40 patients with diabetes will be included in the cohort of patients admitted to medical ward (hospitalisation cohort). The primary hypothesis is that levels of plasma glucose have clinically significant impact on left ventricular systolic function in patients with COVID-19 admitted to the ICU. The secondary hypothesis is that the impact of plasma glucose on left ventricular systolic function is associated with glycaemic control prior to admission as measured by HbA1c.
It still unclear how SARS-CoV-2 affects pregnant women and their offspring, as well as which factors may influence obstetrical disease and outcomes, including the timing of maternal viral exposure by gestational age, the effects of parity, age, host immune responses, coexisting medical and obstetrical conditions and the effects of treatment regimens. While further information is gathered, based on the existing evidence from other infections causing pneumonia, pregnant women should be considered to be at high risk for developing severe infection during the current COVID-19 epidemic. Results from clinical trials with HCQ in nonpregnant adults may not be directly extrapolated to pregnant women given the special features of the pregnancy status. Thus, clinical research is urgently needed to improve the care and reduce the risk of poor pregnancy outcomes of women in this and in future epidemics.
To evaluate by intravascular OCT study the presence of microvascular pulmonary thrombosis in patients with COVID-19, high D-dimer levels and contrast CT scan negative for pulmonary thrombosis. We'll also evaluate the extension of microvascular pulmonary thrombosis in patients with contrast CT scan positive for pulmonary embolism in areas where contrast CT scan was negative.
Antioxidants, and particularly polyphenols, have shown protection in respiratory pathologies, which is related to the decrease in the severity of the clinical picture and suppression of inflammation. This suppression of inflammation may be related to the inhibition of NF-kB polyphenols, where its activation is related to the stimulation of 150 stimuli including cytokines (IL-1β, IL-6, THF-α, GM-CSF, MCP-1), TLRs, among others. There may be other additional mechanisms that can help control virus-induced respiratory pathologies, among which are the regulation of reactive oxygen species (ROS) associated with tissue destruction caused by the virus and a selective antiviral action can be reported. direct. The standardized P2Et extract obtained from C. spinosa, by the Immunobiology Group of the Pontificia Universidad Javeriana, is highly antioxidant, decreases lipid peroxidation and tissue damage and induces complete autophagy in stressed or tumor cells. The induction of a full autophagic flow could inhibit the replication of beta-coronaviruses like SARS-CoV-2. Furthermore, P2Et can decrease the factors involved in tissue damage by reducing IL-6 and decrease ILC2 cells of the lung in animals with lung metastases (unpublished data). These antecedents suggest that the supplementation of patients with COVID-19 with the extract P2Et, could improve their general condition and decrease the inflammatory mediators and the viral load.
To find out what adaptations have been made by Inflammatory bowel disease physicians and patients in relation to therapies in flaring IBD patients during severe acute respiratory syndrome 2-COV and what the impact of these is on IBD patients with no symptomatic COVID-19 and in suspected/confirmed COVID-19. Also whether there any IBD related factors impacting the outcome of patients with COVID-19 symptoms or COVID-19 disease
