Filter by:The 2019-20 coronavirus disease, caused by COVID-19, is an ongoing pandemic. The measures in which public health officials quarantine confirmed and isolate symptomatic cases in order to reduce the spread COVID-19 is the common practice used in most countries. However, a significant question remains in regards to the asymptomatically infected individuals, which may propagate the virus and impede infection control. The other question to consider is whether these asymptomatic carriers develop an immune response or continue viral shedding. The purpose of the current study is the evaluate the immune response, i.e developing anti-SARS-CoV-2 antibodies in the asymptomatic cases, in a household study design. We plan to evaluate over 1000 patients with positive COVID-19 results and their households.
This is a proof of concept study to evaluate the efficacy of nitazoxanide (600 mg BID) to treat hospitalized patients with moderate COVID-19.
Protection of endothelial dysfunction by intravenous infusion of Defibrotide (Defitelio), expected to decrease inflammation and expression of adhesion molecules in the endothelium, leukocyte tissue infiltration and epithelial destruction, and to promote immune tolerance through a change in the Cytokine balance, which is decisive in preventing multiorgan failure and death in patients with SARS-CoV-2 infection with clinical status grade 4 or 5 according to the WHO classification
We aim to assess the benefits and harms of low-dose hydrocortisone in patients with COVID-19 and severe hypoxia.
Background: COVID-19 is a worldwide pandemic and currently there is no effective therapy or vaccine. SARS-CoV-2, the virus that causes the COVID-19 respiratory infection, appears to be very contagious however all the modes of transmission are unclear. Transmission may occur in up to 25 percent of cases when there are no symptoms (asymptomatic). Before there are any symptoms, droplet spray during speaking may increase transmission from person to person; most of the spray is saliva. Researchers at the NIH would like to test saliva for the virus before symptoms are reported. Additionally, they would like to examine the importance of using masks to prevent transmission. They hope to better understand how COVID-19 is spread among people and how it can be prevented. For this study they would like to collect samples from the nose (nasopharyngeal swab), mouth (spit sample), eye (conjunctival fluid) and blood to test for the virus and if it is contagious. Objectives: To determine if the SARS-CoV-2 virus is present in saliva in asymptomatic individuals who are COVID-19 positive. To determine if using masks can prevent transmission. Eligibility: People ages 18 and older without symptoms or with mild symptoms (e.g., low grade fever, mild malaise, minor sore throat, runny nose, or sneezing) who have been in close contact (e.g. live in the same house) with someone who has tested positive for COVID-19 or people who have tested positive for COVID-19 and have mild (e.g., low grade fever, mild malaise, minor sore throat, runny nose, or sneezing) or no symptoms. Design and Procedures: For screening, interested participants will contact a study team member. The interested participant will be asked to provide documentation of COVID-19 positive status, their symptoms, or their contact to a COVID-19 positive person. Participants will be asked to come to the NIH drive-up COVID-19 testing site or NIH Clinical Center (Bethesda, MD) for 2 or more visits in 15 days for the following procedures: nasal swab for COVID-19 and viral load, verbal symptom assessment, saliva collection, and speaking exercise to capture oral fluid. During this time, participants will also be asked to participate in phone calls with the study staff and to complete questionnaires electronically. Participants will have weekly telephone calls to discuss their symptoms and 2-5 drive-up visits to the NIH within 28 days. If visits are scheduled at the Clinical Center, participants will have the option to participate in providing blood sample(s), a conjunctival swab and 1-2 salivary gland biopsies. If a participant has tested positive, they may be asked to return to the NIH after they have recovered from COVID-19 for additional sampling. The following procedures are part of this research: - Speaking exercise - participants will be asked to read a short script with and without wearing a mask. The droplets they produce while they speak will be collected. - Saliva collection - participants will spit into a cup and have saliva collected from different areas of the mouth. They should not eat 90 minutes before this but drinking water or juice is acceptable. They may have their tongue painted with a sour liquid to increase their saliva. - Nasal swab- participants will have a swab rubbed inside their nose. - Nasopharyngeal swab - participants that are close contacts of COVID-19 positive individual(s) and need a COVID-19 test, will have a swab inserted through the nose to rub the back of their throat. - Questionnaires - participants will complete questionnaires about their symptoms electronically at home. The following procedures are optional for participants to agree to participate in and will be performed in the Clinical Center: - Blood sample(s) - participants will have blood collection via venipuncture. - Conjunctival swab - participants will have the inner lower eyelid wiped with swab. - Minor salivary gland biopsy - participants will have tiny glands in mouth removed. Procedure will be done in the hospital. Participants will be paid up to a total of $300 for the study, based on the number of visits to NIH and the types of procedures performed. Payment will be: $50 on Day 1, Day 15 and at the recovery visit. Participants who agree to the optional conjunctival swab and/or biopsy will be paid $50 for each conjunctival swab (up to 1) and/or $50 for each salivary biopsy (up to 2). If at any time the participants start to have moderate or severe respiratory symptoms, their participation in the study will end and they should seek care with their local provider.
A prospective investigation and screening of all HCWs working in all governmental university hospitals and the affiliated COVID-19 quarantine hospitals using an online survey and laboratory testing using rapid serological tests and PCR. To date, the Ministry of Higher Education has dedicated quarantine hospitals at the following governmental universities: Ain Shams, Cairo, Helwan, Alexandria, Mansoura, Assiut, Minia. This list may be expanded in the future. The project will be pilot tested in Ain Shams University, then extended to other universities subsequently. For risk categorization of HCWs exposed to COVID-19 virus and assessment of infection control needs, an online survey questionnaire will be administered to all HCWs in the governmental university hospitals involved in emergency and intensive care and in the provision of care for COVID-19 patients in the affiliated COVID-19 quarantine hospitals. For confirmation of infection and determination of the secondary infection rate, paired serological samples at baseline and after exposure will be collected. For measuring the validity of the available rapid serological tests, a respiratory sample will be taken for viral detection by RT-PCR. A real-time interactive map using geographical information system programming will be developed to flag hotspots for HCWs' risk and infection control needs that originated from the online survey risk categorization in governmental university and COVID-19 quarantine hospitals. Policy and decision makers will use the map to manage emergency healthcare resource mobilization based on HCWs' risk and infection control needs.
The study aims to determine the safety and efficacy of povidone-iodine (PVP-I) containing nasal sprays as compared to isotonic saline nasal sprays in COVID-19 positive patients. The primary outcome measure is SARS-CoV-2 viral titers in the nasal cavity and nasopharynx. In vitro studies have shown PVP-I to be highly virucidal against the viruses which cause SARS and MERS. Additionally, clinical studies have shown PVP-I saline sprays to be well tolerated in human subjects. PVP-I oral rinses and sprays have been trialed as methods to reduce the incidence and symptoms of viruses which cause the "common cold."
In the present context, it seems necessary to try to describe as precisely as possible the physiological alterations due to COVID-19. From these observations, therapeutic proposals adapted to this new disease may then be developed, particularly in the symptomatic management of the critically ill patient. It therefore seems essential to rigorously study these modifications, as they have been studied in the past for ARDS. The aim of this non-interventional study is to describe precisely the respiratory and hemodynamic changes induced by COVID-19 in mechanically ventilated patients .
The purpose of this clinical trial is to assess the safety and efficacy of Clevudine 120 mg versus placebo once daily administration with standard of care therapy for 14 days (maximum up to 21 days) in patients with moderate COVID-19.
This non-interventional, observational study retrospectively (and in parts prospectively) investigates, if a Covid-19 associated Nephritis, diagnosed by Urine-dipstick and further Urine-analyses on addmission, can help to predict later complications, adverse outcomes and later need for ICU-capacity in Covid-19 patients as well as can guide preventive strategies.
