Filter by:The classic myeloproliferative neoplasias (MNP), including polycythemia vera (PV), essential thrombocythemia (ET), primary myelofibrosis (PMF) or secondary to PV or ET, are among the most frequent of malignant hemopathies, with overall prevalence estimated at around 10,000 patients followed in France. Due to the median age of patients around 65, the frequency of cardiovascular complications of these thrombogenic diseases and the impact of cytoreductive treatments on immune cells, these patients are considered to be at risk of developing forms severe of COVID-19. This study will assess the impact of MNPs on the risk of developing a severe form of COVID-19, identify new risk factors linked to the disease as well as the impact of treatments for MNPs according to their pharmacological class.
In response to the coronavirus disease 2019 (covid-19) outbreak, the home confinement of the population ordered by governments in many countries raise questions about its impact on individuals' physical and mental health in the short and longer term. In children, reduced physical activity, changes in lifestyle, disturbances in sleep patterns, lack of in-person contact with peers, poor or inadequate understanding of health risks may be risk factors of anxiety, stress, fatigue, sleep disorders. These problematic effects could be modulated by social factors (housing in urban or rural areas, availability of personal space at home, parenting stress, etc.).
In December 2019, a novel coronavirus (SARS-CoV-2) emerged in Wuhan, Hubei, China, and now spreads across international borders. As of 11 April 2020, the total global number of confirmed SARS-CoV-2 cases reached 1,521,252 (92,798 deaths); with 65,081 (7,978 deaths) being reported in the United Kingdom. COVID-19 is the name of the disease associated with SARS-CoV-2 infection and includes a spectrum of illness that ranges from mild infection to severe pneumonia that can progress to respiratory failure and Acute Respiratory Distress Syndrome (ARDS) or septic shock. Between 8 to 15% (depending on geographical setting) of all SARS-CoV-2 positive cases can be classified as severe or necessitating intensive care unit (ICU) admission. In the early stages of the outbreak unfolding, several retrospective case studies and cases series carried out in China reported that those who died were more likely to be male, and more likely to have underlying comorbidities. Prevalence studies conducted in the US and Italy show similar trends in the distribution of comorbidities among SARS-CoV-2 severe cases; adding obesity (BMI>30) to the list of factors potentially associated with disease severity. However, the relative importance of different underlying health conditions remains unclear owing to inadequate adjustment for important confounding factors such as age, sex, and smoking status. We propose a cohort study to evaluate predictors, clinical evolution and excess of mortality of SARS-CoV-2 in hospitalised patients, with two main workstreams- the first looking at all patients admitted to SGHFT and the second looking at patients admitted to ITU with respiratory failure.
This is a phase 3 clinical trial, randomized, single-center, opened, controlled, to evaluate efficacy and safety of early administration of colchicines in patients older than 60 years, with high risk of pulmonary complications due to coronavirus SARS-CoV2 (COVID-19). An approximately number of 954 subjects meeting all inclusion and none exclusion criteria will be randomized either to receive colchicines or symptomatic treatment with paracetamol during 21 days.
Since the start of this epidemic, numerous clinical and fundamental studies have been conducted to best adapt the individual management of COVID-19 cases [1-6]. In parallel with this work, it is necessary to better understand the characteristics of the epidemic in the general population but also in the population working in healthcare settings more exposed to SARS-CoV-2. Seroprevalence studies are therefore particularly useful in order to understand the collective immunization rate and the factors that can explain this immunization.
End-stage organ failure is estimated to affect more than 4 to 6 million persons worldwide. In 2018, transplant systems across the globe enabled around 150,000 patients to benefit from a kidney, heart, lung, liver, or other solid organ, a number that was far less than the demand. According to data from the World Health Organization, more than 1,500,000 persons live with a transplanted organ worldwide. In the US, approximately 40,000 patients receive an organ transplant every year, but 120,000 still remain waitlisted for transplantation today, with 7,600 dying annually while waiting for an organ transplant. A similar lack of organs and high death rates on the waiting list affect patients in Europe and many other countries. As nations adjust to new realities driven by the coronavirus (COVID-19) outbreak, many health care providers, institutions and patients are concerned about the potential impact that COVID-19 will have on organ donation and transplantation. One concern is that transplant recipients may have a greater susceptibility to infection and greater viral burden. A second concern is that hospitals will lack the resources in terms of staff and equipment to care for recipients after transplantation, who often require intensive care and multispecialty management. Because of the overwhelming healthcare system burden, a dramatic negative effect on worldwide organ donation and transplantation is anticipated, but has not been measured. Our objective was to quantify the worldwide impact of COVID-19 pandemic on organ donation and transplantation and consequences for waitlisted patients.
Acute Respiratory Distress Syndrome (ARDS) is the main cause of death from COVID-19. One of the main mechanisms for ARDS is the violent storm of cytokines and chemokines, which cause uncontrolled fatal systemic inflammation by the immune system on the body, with additional multiple organ failure. Mortality in cases of severe ARDS caused by COVID 19 varies significantly between 50 and 90%, basically depending on the age of the patient and the presence of comorbidities. The plasticity of Mesenchymal Stem Cells (MSC) regulates inflammation and immunity. MSC can promote and inhibit an immune response, depending on the dynamics of inflammation and depending on the activation force of the immune system, the types of inflammatory cytokines present, and the effects of immunosuppressants. Essentially, the state of inflammation determines the immunoregulatory fate of MSC. Thus, IV application of AMSCa has been shown to control the inflammatory response in various diseases, such as the graft-versus-host reaction and the ARDS caused by H5NI. The objective of this study is to describe the clinical changes secondary to IV administration of MSC allogenic, in patients with bilateral COVID-19 pneumonia complicated by severe ARDS, with the evaluation of the PaO2 / FiO2 ratio, heart and respiratory rates, and the fever curve. Five patients, of either sex, over 18 years of age, with bilateral pneumonia caused by COVID-19 and severe SIRA that has not improved with the standard management measures used at that time in the care center, will be included in the study. This treatment will be administered after discussing it with the relatives that it is a procedure considered as rescue and will be carried out with informed consent. 1x10(6) xKg will be applied IV. The follow-up of the patient will be for three weeks. PaO2 / FiO2 data, fever, inflammatory markers and immunity will be evaluated. The results will be compared with the historical controls attended at INCMNSZ.
Until now there is no vaccine or reliable treatment for the COVID-19 pandemic. The fundamental mechanisms of non-invasive low-level laser in photobiomodulation (PBM) and photodynamic therapy is to stimulate the mitochondrial respiratory chain where a transient release of non-cytotoxic levels of reactive oxygen species (ROS) will lead to positive modulation of the immune response. As previous studies mentioned that the most important strategy for COVID-19 management is oxygenation and faster rehabilitation of the damaged tissue, antiviral effects, and, finally, reduction or controlling the cytokine storm by reducing inflammatory agents. PBM may be used as adjuvant therapy or even an alternative therapy in all these mechanisms without side effects and drug interactions. Objectives The objective of this clinical trial is to use the photobiomodulation therapy (PBMT), and photodynamic therapy as adjuvant therapy or even an alternative therapy for Covide-19. Patients and methods A randomized controlled study will be conducted on 60 patients of positive COVID 19. The patients will be divided into 3 equal groups. Group, I will receive a low-level laser (diode laser 980nm) from laser watch for 30 minutes, 20 J for 3 to 5 days, and laser acupuncture. Group 2 will be treated with photodynamic therapy by injecting the methylene blue as a photosensitizer and irradiated with laser watch (diode laser 670 nm). Group 3 will serve as a control. Evaluation methods will include laboratory investigations and CT chest.
COVID-19, the infectious disease caused by the novel coronavirus SARS-CoV-2, currently poses a global economic, social, political and medical challenge. The virus originated in December 2019 in Wuhan, China, and has spread rapidly around the world. Currently, European countries, including Austria, are severely affected.The most common computed tomographic changes in acute lung injury include bilateral and subpleural milk glass opacity, consolidation in lower lobes, or both. In the intermediate phase of the infection (4-14 days after the onset of symptoms) a so-called "crazy paving" may occur. The most prominent radiological changes occur around day 10, followed by gradual resolution, which begins two weeks after the onset of symptoms. Given the phylogenetic relationship between SARS-CoV-1 and SARS-CoV-2, the similar clinical course in severe cases and overlapping CT patterns in the acute setting, persistent radiological and pulmonary functional changes in survivors are conceivable. It is also conceivable that a proportion of survivors will develop progressive ILD, either due to viral or ventilator-induced alveolar damage, or both. Here, the investigators intend to investigate COVID-19 survivors through clinical examinations, functional lung examinations, HR-CT scans, and by determining the "immunofibrotic" pattern in peripheral mononuclear cells (PBMCs) 1, 3, and 6 months after discharge.
Hong Kong public healthcare system is facing tremendous pressure under the COVID-19 pandemic. As the virus spread in Hong Kong, Hong Kong Sanatorium & Hospital (HKSH) is one of the first private hospitals which immediately provide reliable and rapid COVID-19 test -- Reverse Transcription Polymerase Chain Reaction (RT-PCR). Early provision of the RT-PCR screening test for COVID-19 not only facilitates identification of COVID-19 but also contains the spread of the virus in the community and frontline medical staff. Since description of role of private hospital in Hong Kong amid COVID-19 pandemic is lacking, this study will describe COVID-19 screening algorithm and methodology. A retrospective analysis on clinical characteristics, laboratory findings as well as outcome of patients who underwent COVID-19 test in HKSH is also performed.
