The solution to the sequelae of "COVID-19 toes"

Scientists have found an explanation for why some people with COVID-19 develop painful lesions on their toes and fingers.

"COVID-19 toe syndrome" appears to be a side effect when the body goes into attack mode to attack the SARS-CoV-2 virus.

A team of researchers at the University of Paris (France) say they have pinpointed the parts of the immune system that seem to be involved in the syndrome. This finding could aid in the treatment of patients.

“COVID-19 toe” can occur at any age, but is more common in children and adolescents. The affected skin, usually the toes but sometimes the fingers, will turn red or purple. For some people, they are painful and itchy, accompanied by blistering or pus-like discharge.

This symptom usually lasts from a few weeks to several months. People who experience it do not show typical symptoms of COVID-19 such as persistent cough, high fever, loss of taste.

Research has just been published in the British Journal of Dermatology, showing that two parts of the immune system may be the cause of "COVID-19 toes". Both are related to the mechanisms the body uses to fight the SARS-CoV-2 virus.

One is an antiviral protein called interferon type 1, and the other is an antibody that mistakenly attacks the person's own cells and tissues. The portion of cells that conduct small blood vessels that supply the affected skin is also involved.

This syndrome usually goes away on its own, but if the patient is in too much pain, they will need extra creams and medication.

Dr Veronique Bataille, consultant and spokesperson for the British Dermatology Foundation, said "COVID-19 toe" is more common in the early stages of the pandemic and less common in current outbreaks due to Delta-induced variation.

According to Bataille, this may be because more people are now vaccinated or have antibodies to COVID-19 after a previous infection with the virus.

That could be because more people are vaccinated or have some protection against Covid from past infections.
