Filter by:The number of new Coronavirus-2019 (Covid-19) cases is increasing day by day despite the warnings "Stay at home! Wear a mask! Keep social distance!". The aim of this descriptive study is to determine the risk factors that affect the Covid-19 infection in Turkey. The online link of the form created on Google forms was sent to the participants' phones between 18.10.2020 and 18.11.2020.
The purpose of this study is to Understand the natural history of Coronavirus 2019 (COVID-19) infection to better define the period of infectiousness and transmissibility and to establish biobanks of COVID-19 blood and mucosal samples.
Aim:There is still not enough data to determine methylprednisolone treatment timing, dosage, duration of use and indication in Covid 19 pneumonia. The aim of this study is to examine the relationship between drug dose and hospitalisation time and mortality rates in patients with pre-diagnosis of severe covid pneumonia and systemic methylprednisolone. Materials and Methods: The demographic data, symptom durations, thorax CT findings, methylprednisolone dose and duration of treatment, hospitalisation times, intensive care hospitalizations of the patients who were initiated and hospitalized in the emergency department will be retrospectively recorded. Finally, the fate of the patients (such as discharge, referral, death) will be recorded.Statistical analysis will be conducted using the Statistical Package for Social Sciences (SPSS) (IBM Corp. Released 2015. IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp.) program.
The aim of this study is to evaluate the efficacy and safety of Mefloquine as a prophylaxis against SARS-Cov-2 infection in household contacts of COVID 19 confirmed. This study is an open-label, randomized, placebo controlled trial. A total of 1500 household contacts of COVID-19 confirmed cases who will attend triaging clinic of 5 Egyptian university centers (Helwan university hospital, Ain Shams university hospital, Assiut University Hospital, Fayoum university hospital and Tanta university hospital). The household contacts of COVID-19 confirmed subjects with a decision for home-isolation will be recruited to participate into this study. The recruited subjects from each center will be randomly assigned (locally in that center) into 2 groups (750 volunteer in each group). The 1st group will receive Mefloquine (1100-1650 mg according to body weight), orally, while the other group will receive the same number of placebo tablets (control group). Previous infection will be excluded for all recruited subjects by testing for the presence of anti-bodies against COVID-19 to exclude previous infection. Subjects who are tested negative will be allocated into one of the 2 study groups after randomization, and treatment will be started immediately (either mefloquine or placebo). In addition, a nasopharyngeal swap will be taken from each recruited subject and tested by PCR for COVID-19 to exclude current infection. After having the PCR results, positive cases will be analyzed separately to test for the disease severity. Neurological and cardiac assessment will be done for all volunteers before recruitment to exclude the presence of any contraindication for Mefloquine intake. Both groups will be followed up clinically to detect any symptom or sign of COVID-19 infection for 2 weeks (during the period of home isolation). Nasopharyngeal swap with PCR for COVID-19 will be done for all included subjects at the end of the follow-up period (14 days), or at the appearance of symptoms or signs suggesting COVID-19 infection. Primary end points of the study are either: - End of follow up period (2 weeks) - Confirmed diagnosis of COVID-19 infection during the study time Initial severity assessment of COVID-19 infection will be done in all infected subjects in both groups to compare severity, in addition to following up of the fate of the infected subjects.
This is a single arm, pilot multicenter prospective study in up to 22 participants with relapsing multiple sclerosis. Patients screened for the study can either be scheduled for vaccine, have received a single vaccine with a scheduled second dose, or already completed full course (two dose) vaccination. Fully vaccinated participants must be able to complete immune assay No.1 ≥ 14 days after the second dose of vaccine
A Randomized, Double-Blind, Placebo-Controlled, Clinical Trial to Evaluate the Safety, Tolerability, Efficacy, and Pharmacodynamics of ADX-629 Administered Orally for the Treatment of COVID-19
Widespread testing and contact tracing are critical to controlling the COVID-19 epidemic. Distribution of COVID-19 self-test kits can augment public health contact tracing efforts, as individuals with COVID-19 can distribute self-testing to close contacts. This approach can increase case detection by facilitating testing among exposed individuals, and potentially ameliorate stigma, fear, and medical mistrust associated with COVID-19 among vulnerable populations. The central hypothesis of this study is that distribution of SARS-CoV-2 self-tests to close contacts of among individuals with COVID-19 infection can increase case detection compared with a standard contact referral strategy.
This pilot double-blind randomized controlled trial will test the preliminary efficacy of two doses of a combination of live microbials (probiotics) given to boost the immunity of unvaccinated persons previously infected with SARS-CoV-2.
The PACAAP study aims to report the seroprevalence of SARS-CoV-2 IgG antibodies among HCWs testing during the massive campaign screening set up in France by French ministry of Health and national authorities in four hospital of the Alpine region.
As of August 16, 2020, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been responsible for more than 21 294 000 infections and about 760 000 deaths worldwide. Accumulating evidence suggests that patients with severe acute COVID-19 pneumonia have a cytokine storm syndrome, or unbalanced hyper-inflammatory response. It is now well known that GcMAF plays a crucial role in immune system regulation as a primary defense against infections. Thus, this multifunctional protein, released into the blood stream, acts as a systemic immune modulator without pro-inflammatory activities. In an animal study, IL-6 level was shown to be dramatically decreased after 21 days of oral administration colostrum MAF. Indeed, data from previous studies and clinical practice have been reported its effectiveness and safety in the treatment of many pathologies such as infectious diseases, some types of cancer, juvenile osteopetrosis, immunological, and neurological diseases. These observations suggest that oral immunotherapy with colostrum-MAF is potentially an effective and well-tolerated treatment for COVID-19 pneumonia. In addition, gastrointestinal involvement is well known in coronavirus infections of animals and humans. The angiotensin-converting enzyme II (ACE2), the entry receptor for SARS-CoV, is highly expressed in proximal and distal enterocytes that are directly exposed to foreign pathogens. It considers the mechanism of SARS-CoV-2 can actively infect and replicate in the gastrointestinal tract. SARS-CoV-2 indirectly damages the digestive system through a chain of inflammatory responses. Delivered topically to the small intestine by an acid-resistant enteric-coated capsule colostrum MAF can directly activate a large number of gut mucosal macrophages for virus control, localizing intestinal inflammation and resolving through driven phagocytic scavenger function. Macrophages in the gastrointestinal mucosa represent the largest pool of tissue macrophages in the body, which besides the local functions are directing the systemic immune response.
