Filter by:A recent report in Physiolological Reviews proposed that the endogenous protease plasmin acts on SARS-CoV-2 by cleaving a newly inserted furin site in the S protein portion of the virus resulting in increased infectivity and virulence. A logical treatment that might blunt this process would be the inhibition of the conversion of plasminogen to plasmin. Fortunately, there is an inexpensive, commonly used drug, tranexamic acid, TXA, which suppresses this conversion and could be re-purposed for the treatment of COVID-19. TXA is a synthetic analog of the amino acid lysine which reversibly binds four to five lysine receptor sites on plasminogen. This reduces conversion of plasminogen to plasmin, and is normally used to prevent fibrin degradation. TXA is FDA approved for the outpatient treatment of heavy menstrual bleeding (typical dose 1300 mg p.o. TID x 5 days) and off-label use for many other indications. TXA is used perioperatively as a standard-of-care at UAB for orthopedic and cardiac bypass surgeries. It has a long track record of safety such that it is used over-the-counter in other countries as an antiviral and for the treatment of cosmetic dermatological disorders. Given the potential benefit and limited toxicity of TXA it would appear warranted to perform randomized, double-blind placebo controlled exploratory trial at UAB as a prophylactic antiviral treatment following exposure to COVID-19 in order to determine whether it reduces infectivity and virulence of the SARS-CoV-2 virus as hypothesized. Involvement of each patient is only for 7 days before primary endpoints and 30 days for final data collection.
Evaluate the safety pharmacokinetics and pharmacodynamics (PK/PD)of a single dose of Kamada anti-severe acute respiratory syndrome (SARS)- CoV-2 in patients hospitalized with COVID-19 caused pneumonia
The increase of all-cause mortality in the areas with high COVID-19 transmission rate due to COVID-19 deaths and the collateral damage to other healthcare problems is well known. However, the COVID-19 mortality is very low in the regions with low transmission rate and sufficient medical resources. In such regions, strict prevention measures were taken and these would alter the people's lifestyle and hygienic habits and further impact on non-COVID-19 deaths. Yet, there has no thorough investigation in this aspect.
Up to 1/3 of all patients infected with COVID-19 can develop complications that require hospitalization. Severe pneumonia associated with acute respiratory distress syndrome (ARDS) is the most threatening and feared complication of COVID-19 infection, with mortality rates close to 50% in some groups. Autopsies between these severe cases reveal severe capillary involvement, with signs of intense inflammatory changes, microvascular thrombosis, endothelial injury and abnormal tissue repair. The available evidence suggests that abnormal activation or imbalance in the counter-regulation of the kallikrein-kinin system may play a central role in a positive feedback cycle, leading to consequent diffuse microangiopathy. Blockade of the kallikrein-kinin system can therefore prevent deterioration of lung function by reducing inflammation, edema and microthrombosis. The objective of this phase IIb study is to assess the preliminary effects on the oxygenation parameters of an antisense oligonucleotide that inhibits pre-kallikrein synthesis in patients with moderate to severe COVID-19.
GEN-COVID multicenter study aims to identify the genetic variants of the host genome responsible for the clinical variability of patients with COVID-19. This variability to date is only partially related to the age and comorbidities of patients. The primary objective of the study is therefore to identify genetic variants associated with the severity of the disease, while the secondary objective consists in the identification of variants associated with longitudinal disease trajectories. This is a laboratory study that involves the conduct of genetic investigations, including whole exome sequencing and genome wide association studies, on human biological material from patients affected by COVID-19. Clinical information useful to describe the level of disease severity will be also collected for each enrolled patient. A total of at least 2,000 COVID-19 patients is expected to be included.
Little is currently known about the immediate and long-term effect of COVID-19 on lung ventilation (delivery of air to the lungs) and lung perfusion (delivery of blood to the lungs). Some people who survive COVID-19 may have lung ventilation and/or perfusion injury that persists following COVID-19 recovery. This lung injury may be related to inflammation in the lung, breathlessness, exercise limitation and reduced quality of life. Therefore, towards the goal of understanding the effects of COVID-19 on lung health, the purpose of this study is to characterize and understand the clinical relevance of COVID-19 related lung ventilation and perfusion injury and associated inflammatory status, ≤4 weeks and 6-months following COVID-19 recovery in an asthmatic and healthy population. To do this, an asthmatic and healthy population who have, and have not, been previously diagnosed with COVID-19 will be studied.
It is an established fact that, corona virus spread through the respiratory droplets. Colonization of the virus in oropharynx and/or nasopharynx is considered to be major factor for transmissibility of the virus through respiratory secretions. Preventing colonization of the virus by administrating povidone iodine in the nasal passage therefore, a rational thought which is supported by recent evidence of in-vitro virucidal action of povidone iodine in Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS CoV-2). Therefore, the study is designed to assess the virucidal effect of povidone iodine on COVID-19 virus in-vivo.This open label randomized clinical trial will be conducted at Department of Otorhinolaryngology and Head Neck Surgery, in collaboration with Department of Virology and Department of Medicine in Dhaka Medical College (DMC) Hospital. The study will be conducted from September 2020 to October 2020. Total 175 confirmed cases of COVID-19 disease, proven by Reverse transcription polymerase chain reaction (RT-PCR) testing will be enrolled in this study. Written informed consent will be ensured before participation. In case of no literacy, finger print will be considered for written permission.Consent will be sought from the legal guardian in case of minor or underaged.Formal ethical clearance will be taken from Ethical Review Committee (ERC) of Dhaka Medical College. All of the Participants will be divided into seven groups: Group A will receive Povidone iodine (PVP-I) nasal irrigation at concentration of 0.4%, Group B and Group C will received 0.5% and 0.6%; Group D will receive PVP-I nasal spray at concentration of 0.5% and Group E will received at 0.6% concentration. Group F (Placebo comparator group) will receive nasal irrigation by distilled water (DW) and Group G (Placebo comparator group) will received nasal spray by distilled water. The contact time will be minimum 30 seconds. After the individual application of PVP-I and distilled water in respective participant, they will be tested again for RT-PCR for COVID-19 from nasopharyngeal and oropharyngeal sample. All patients will be subjected to detail history, physical examination and adverse events. Block Randomization will be followed for randomization. Data will be recorded in a semi-structured questionnaire and will be analyzed by 'R-4.0.2' data analysis software
This current protocol encompasses an investigator-blinded randomized exercise intervention in 10 COVID-19 survivors that have been discharged from hospital. The subjects will be randomized to perform three different exercise training protocols in a random order. The aim is to clarify the feasibility and safety of three training protocols in COVID-19 survivors. The hypothesis is that patients surviving COVID-19 will be able to comply to all training protocols.
The aim of this study is to evaluate the prevalence of COVID-19 among the workers of our hospital and the factors that are likely to influence this prevalence. It must be underlined that our hospital is settled in two towns and both hospital sites had different missions regarding the admissions of COVID-19-infected patients.
Solving the problem of detecting asymptomatic carriers who can transmit infection is key to protecting vulnerable residents of nursing homes and assisted living facilities, to protecting frontline workers who care for them, and to facilitating return to work (including return of nurses and medical assistants). The wearable biometric technology, if widely disseminated among vulnerable populations and the community-at-large, will help avoid the ravages of seasonal flu and other contagious illnesses, and the society will be better prepared for future waves of COVID-19 or other pandemics. Even if a vaccine is developed, due to immune senescence and immunocompromise, elderly people and those with chronic medical conditions may not be well protected by it. Continuous biomonitoring provides another layer of protection for them.
