Clinical and Mechanistic Study of Patients (With COVID-19 or Not) With a Recent Acrosyndrome (ACROCOVID)
Clinical and Mechanistic Study of Patients With a Recent Acrosyndrome
The recent and unexpected occurrence of patients with the development of skin lesions on the hands and/ or feet has been described recently. As these cases occurred contemporaneously with the Coronavirus Disease 2019 (COVID-19) and as it was the most often occurrence of de novo frostbites, the question raised of whether there is a direct link between the occurrence of these lesions and infection of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) the responsible for CoVID-19. Indeed, mechanisms of these lesions and the precise correlation with Sars-CoV-2 remains poorly understood. Therefore, this study aim to:
- Determine the possible link with this virus,
- Understand the mechanisms involved in the pathogenesis of these lesions.

Intervention / Treatment
Detailed Description
In this study, the investigator designed a prospective interventional study in order to collect blood samples and skin lesion biopsy at significant time points in patients who present a skin lesion. The intervention in this study is limited to some blood samples and skin biopsies.
Two 7 mL tubes of blood will be collected at consultant time for essentially serological test for the SARS-CoV-2 and for analysing certain populations of white blood cells. The second additional blood sample of 7 mL will be collected around day 15 after inclusion in a dry tube to perform a serological test for SARS-CoV-2 at a distance from the onset of skin signs.
A biopsy for histological study is usually done in patients with acrosyndrome. This is why this type of biopsy will be done as a routine care of these patients. An immunohistochemical study could complete the histological explorations using an anti-coronavirus antibody if arguments in favour of SARS-CoV-2 are demonstrated. In this study, patients who accept and sign informed consent will be proposed a skin biopsy on a characteristic lesion for freezing. This biopsy can be used for transcriptomic analysis. This may allow a better understanding of the mechanisms of the disease.
