NCT ID: NCT06237517 Completed - Thermoregulation Clinical Trials

Assessment of Vasomotion of People With Idiopathic Chilblains

Start date: March 15, 2022
Phase: N/A
Study type: Interventional

Chilblains, also known as perniosis, is a non-freezing cold injury causing painful inflammatory skin lesions. Chilblains typically affect the dorsal feet or hands, causing inflammatory skin lesions that are often painful, and their pathogenesis remains only partly understood. To improve diagnosis and management, it is vital to focus entirely on chilblains and consider the patient-related and environmental factors that characterize this disorder. Because of this, it's critical to investigate the thermoregulatory function, of individuals with idiopathic chilblains while they are exposed to various environmental conditions (cold and neutral environments).

NCT ID: NCT04455308 Completed - COVID-19 Clinical Trials

COVID-19 and Chilblains

ECCES
Start date: July 21, 2020
Phase: N/A
Study type: Interventional

Chilblains (inflammatory lesion of the feet or hands) have been reported with an unusual frequency during the confinement period, most commonly in children, teenagers and young adults. The aim of the ECCES study is to find out whether these manifestations of chilblains can be linked to the SARS-CoV-2 coronavirus. For this, an epidemiologic study will compare two types of family (or more precisely people who were confined together in March-April-May): - "case family" in which at least one of the members had chilblains - "comparator family" in which none of the members had chilblains Environment (home lockdown) of the two types of family will be analyzed. Each member of the "family" will be suggested doing a serological test.

NCT ID: NCT04387955 Completed - COVID-19 Clinical Trials

Analysis of Chilblains pROfile During coVID-19 Epidemic (ACROVID)

ACROVID
Start date: April 30, 2020
Phase: N/A
Study type: Interventional

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.
