Filter by:Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Lung failure is the main cause of death related to COVID-19 infection. The main objective of this study was to evaluate if ibrutinib is safe and can reduce respiratory failure in participants with COVID-19 infection.
SARS-CoV-2 belong to beta-coronavirus family and its transmission route and symptoms follow those of all community-acquired coronaviruses. The main difference of the novel Coronavirus is the higher mortality rate, that is around 3%. Death rate is over 1% only for patients over 50 years old, whereas until 40 years old is under 0,4%. No fatalities are declared among children under 10 years old to date. Death rate is almost double for male rather than female. This distribution of mortality rate according to age of infected patients could be only partially ascribed to other comorbidities in addition to great age. In fact, patients with no pre-existing conditions have however a case fatality rate of 0,9%. The almost null rate of severe illness in children and generally in patients younger than 40 years old is quite un-explicable. Infant, children and young people could be infected but infection is rapidly self-limited or without symptoms. Older patients undergo severe lung injury as consequence of an immune response that is late in coming. Possible explanation of these phenomena could be something, which assure ability to prompt response to SARS-CoV-2 in younger people independently from the novelty of the virus itself. It would seem to be that younger people are already sensitized to the antigens of the virus without a previous contact. This immunity is not really specific, but "partially specific" for many antigens of the virus, however able to limit the infection in the organism. Something stimulated the immune system and it scattered immunity against more and more antigens present. Children are the age group mostly exposed to all community-circulating viruses. This immunity is not persistent but progressively fade out. It protects from the age of two, when the hypothetical stimulation occurs, to the fifth decade because of its slow decrease. The only external stimulation, which healthy people receive are vaccines. All vaccinations and especially tetanic, diphtheria toxoids and inactivated bacteria as pertussis could stimulate immune system. They develop the specific immunity but generate also a sprouting immunity against antigens in transit, as coronaviruses and other community-circulating viruses. The developed immunity gives some protection against multiple viral infection for years until the natural fade out. After the fifth decade, that immunity is slower to be recall and reactivated. Additionally, transplant recipients and HIV infected patients, which have an immune system inhibited, unexpectedly, do not seem to suffer the worst complications of SARS-CoV-2 infection. An immune system imbalance could be play a pivotal role during the reaction to the virus, limiting destructive consequences of excessive inflammation. According to the medical hypothesis on which the protocol is based on, young people could benefit from a functional adaptation of innate immune cells induced through epigenetic reprogramming and, especially, a pre-existing "partially specific" immunity to the community viruses caused by "bystander effect" of preceding vaccinations. In this study, we will explore the main differences existing among patients infected by SARS-CoV-2 who experience the illness at different degree of severity. We suppose to recognize different populations of patients, each one with a specific immunological pattern. It could differ in terms of cytokines, soluble factors serum level and immune cells activity both of the innate compartment and of the acquired one. The proof of a role of these immunological phenomena in the pathogenesis of Covid-19 are bases for implementation of therapeutic immunomodulatory treatments. In addition, the definition of an immunological risk profile could tailor established therapies to each kind of patient.
Currently there is no standard treatment for SARS-CoV-2 infection. Use of convalescent plasma has been studied in outbreaks of other respiratory infections, including SARS-CoV-1 , MERS-CoV and Hantavirus infection. This study is an open-label randomized trial in which patients with high risk of COVID19-associated respiratory failure will be randomized to early treatment with convalescent plasma (≤ 7 days from symptoms start) or at early signs of respiratory failure or prolonged hospitalization. COVID-19 convalescent plasma will be collected from individuals according to the institutional protocol.
On 11 March 2020, the World Health Organization declared SARS-CoV-2 (commonly called COVID-19) a global pandemic. As in any pandemic, maintaining the health and safety of the healthcare workforce is of great importance as health care workers (HCW) remain a critical line of defence against the spread of COVID-19 and play a vital role in the recovery of those already infected. Frontline HCW, such as those in the emergency department (ED), are at high risk of contracting COVID-19 due to their close proximity to patients who may have the virus. The impact of frontline HCW becoming ill and thus unable to go to work is equally high, and of grave risk to the function of the healthcare system and the ability to minimize the impact of the current pandemic. This study aims to evaluate whether hydroxychloroquine (HCQ), a well-tolerated drug typically used in the prevention of malaria transmission and rheumatic disease, taken before and during exposure to patients with COVID-19, is effective at reducing COVID-19 infections among ED health care workers.
Severe COVID-19 patients at a high risk of venous thromboembolism. We studied patients in 2 intensive care units of university hospitals in Barcelona and Badalona, Spain. We performed a cut-off screening of deep venous thrombosis (DVT) with bilateral duplex ultrasound to 230 patients.
This is a single arm phase II trial to assess efficacy and confirm safety of infusions of anti-SARS-CoV-2 convalescent plasma in hospitalized patients with acute respiratory symptoms,with or without confirmed interstitial COVID-19 pneumonia by chest Xray or CT. A total of 29 eligible subjects will be enrolled to receive anti-SARS-CoV-2 plasma.Outcomes will be compared to hospitalized controls with confirmed COVID-19 disease through retrospective chart review.
Plasma exchanges with 5% human albumin (2/3 of the exchanged plasma volume) and fresh frozen plasma (FFP: 1/3) in patients with quick <50% or only with 5% albumin in patients with quick of 50% or more. We will exchange between 1.2 and 1.5 plasma volumes, that will vary according to sex, weight, height and hematocrit.
The primary objective of this multi-center study is to clarify the value of a CRP measurement for triage of patients initially presenting with light symptoms of the COVID-19 infection. Current recommendations of management of COVID-19 include large-scale tests for virus. Such tests reveal whether an individual is infected with the virus, however, the demonstration of virus per se has no prognostic value for the ensuing course of the COVID-19 disease. Publications of possible treatments strategies increase exponentially, while evidence of triage of the affected individuals is mainly based on the level of pulmonary affection as measured by the Oxygen saturation. To inform decision making for which patients are to be hospitalized due to risk of developing more severe affection, this study addresses the question, whether triage may be performed with the aid of a simple CRP measurement.
Currently we do not know how best to treat patients infected with COVID-19. This study is looking at whether randomising participants to either favipiravir or to usual care, can help patients with suspected or proven COVID-19 infection.
Prospective, mono centric study on COVID-19 patients with or without acute respiratory distress syndrome (ARDS) to analyse the dynamics of the immune response and to search for biomarkers of evolution
