Prevalence of Critical Forms of CoVid-19 in Patients With Chronic Respiratory Disease

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.

Inclusion Criteria:

• Age greater than or equal to 18 years of age
• Diagnosis of CoVid-2 SARS infection retained (from clinical presentation, radiological and CoVid-19 positive microbiological specimen).
• Hospitalisation in the conventional medical sector for "respiratory" reasons (= severe form of CoVid-19) in the Nancy-Brabois hospital and Metz-Thionville Hospital between 02/03/2020 and 15/06/2020.

Exclusion Criteria:

• Diagnosis of SARS-CoV-2 infection not retained
• Refusal of the patient to participate in the study
• Persons referred to in Articles L. 1121-5, L. 1121-7 and L1121-8 of the Public Health Code: o Pregnant woman, parturient or breastfeeding mother o Minors (not emancipated) o Persons of full age subject to a legal protection measure (guardianship, curatorship, safeguard of justice) - Persons of full age unable to express their consent Persons deprived of their liberty by a judicial or administrative decision, persons subject to psychiatric care by virtue of articles L. 3212-1 and L. 3213-1.
