Clinical Trial Summary

Cases of chilblains have been reported with an unusual frequency in France in the context of the COronaVirus Infectious Disease 2019 (COVID-19) epidemic. Some of these cases have been linked to a virological status in favour of a recent Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2) infection. Chilblains are acral inflammatory lesion typically reactive to cold (primary form). There are secondary forms acquired during autoimmune connectivitis such as lupus chilblain or hereditary forms related to type I Interferonopathy. An interferon type I signature has been described in these secondary forms of frostbite but also during the cytokine storm of severe forms of CoV-2 SARS infection. If cases of frostbite are indeed secondary to an SARS-CoV-2 infection, comparative analysis of their immunopathological profiles could provide a better understanding of the inflammatory mechanisms during COVID-19.
