1 A Prospective Non Interventional Study to Evaluate the Role of Immune and Inflammatory Response in Recipients of Allogeneic Haematopoietic Stem Cell Transplantation (SCT) Affected by Severe COVID19 Infection

COVID19 pandemic currently represents a public health emergency. Based on current data, 15% of the affected individuals will develop a severe form of the disease requiring admission to hospital and respiratory support. Data show that age and cardiovascular pre-existing comorbidities predict a poorer outcome. Some evidence suggests that a subset of patients with poorer outcome present with a cytokine mediated inflammatory response and with a secondary HLH like clinical phenotype. No data are so far available with regard to the risk of severe COVID19 disease in the post stem cell transplantation setting. Recipients of allogeneic stem cell transplantation are by definition immunologically dysregulated and could potentially present with a unique immune-inflammatory response to COVID 19 infection. Moreover, the immunosuppression used to prevent/treat GVHD may also impact clinical progression and it is possible that because of their immunological defects, SCT patients could potentially have prolonged carriage of the virus and hence act as "super spreaders". The present study aims at documenting clinical and biological characteristics, including immunological profiling, of allogeneic stem cell transplant recipients presenting with severe COVID 19 infection and its impact on patients survival. This work may provide the scientific basis for targeted therapy with biological agents in this patient group.

2 The Clinical Difference Between the Nonfatal Coronavirus Disease 2019 (COVID-19) Patients and the Fatal Cases With Severe COVID-19

To investigate the difference of the difference between the nonfatal Coronavirus Disease 2019 (COVID-19) Patients and the fatal Patients .The cross sectional study was undertaken to compare the clinical information (laboratory and radiologic characteristics)of nonfatal participants and fatal cases. The investigators wish figure out the clinical character of the fatal participants. The result may help the physician to find the fatal patients with COVID-19 more easily. The fatal patients with COVID-19 could be treated early.

3 Evaluation of the Prevalence of Critical Forms of CoVid-19 in Patients With Chronic Respiratory Disease Hospitalized for Severe Forms

A new Coronavirus (SARS-CoV-2) emerged in Wuhan Province, China in December 2019 and rapidly spread around the world. To date, the data in the literature regarding the clinical and epidemiological characteristics of severe forms of CoVid-19 in patients with chronic respiratory disease are not well known. The hypothesis is that patients with chronic respiratory disease (COPD, asthma, bronchial dilatations, pulmonary hypertension, cystic fibrosis, obesity-hypoventilation syndrome, obstructive sleep apnea syndrome) infected with SARS-Cov-2 will have increased dyspnea and hypoxemia leading to hospitalization for severe forms more frequently than the general population. However, they do not appear to be more at risk of developing a critical form. This study is carried out in order to propose to estimate the prevalence of critical forms of CoVid19 among patients with chronic respiratory diseases hospitalized for severe forms.
