What we know

Psoriasis is a common skin disease affecting 2-4% of people worldwide. It is caused by an overactive immune system, and affected individuals develop red, scaly patches of skin that can be itchy and painful. The condition can also have a profound impact on physical and emotional wellbeing.

It is not currently understood how COVID-19 affects people with psoriasis, and whether there is a need for clinicians and patients to consider adapting their usual immunosuppressant treatments.

What is COVID-19?
COVID-19 (Coronavirus disease) is an infectious disease caused by a newly discovered coronavirus (a large family of viruses which may cause illness in animals or humans). The most common symptoms are fever, dry cough and loss of or change to taste and smell. There are a range of other symptoms which are less well understood at this time.

  • Around 125 milllion people worldwide have psoriasis

  • Around 1 in 3 people with psoriasis has a relative who has the disease

  • Psoriasis is linked to other long term conditions such as diabetes, heart disease and depression

What we are doing

Our researchers and clinicians have launched two global registries to understand the impact of COVID-19 on people with psoriasis.

The PsoProtect registry collects data from clinicians around the world on patients with psoriasis and COVID-19, while the PsoProtectMe registry collects data from patients themselves (whether or not they have had COVID-19) on their experiences and behaviours in the pandemic.


How will this change care

“The PsoProtect registry has the potential to improve our understanding of how underlying medical conditions and the treatments we use for psoriasis affect outcomes of COVID-19 in people with psoriasis. This information may help inform assessments of risk of COVID-19 in people with psoriasis and guide clinical decision making around their treatments in the pandemic.

“By collecting information directly from patients using PsoProtectMe, we also hope to gain a better understanding of the experiences and health behaviours of everyone with psoriasis during the pandemic. “Thank you to everyone who has contributed to the registries so far.”
