Psoriasis patients more susceptible to COVID-19

As the COVID-19 pandemic has continued, researchers have been able to study individual groups of patients with pre-existing medical conditions – including psoriasis.  One especially important question, is whether patients diagnosed with psoriasis, could be more at risk of infection with COVID-19?  

In a recent (virtual) meeting of the American Academy of Dermatology (AAD), evidence was presented to suggest that psoriatic patients do indeed have a significantly higher risk of contracting COVID-19 infection, when compared with the general population.  The data used for the study was from the Symphony Database, a cloud-based platform containing around 280 million patients.   Baseline characteristics showed psoriasis patients were more likely to be white and had a higher proportion of COVID-19 risk factors including heart failure, type-2 diabetes mellitus, obesity, and chronic lung disease. 

Overall (and using statistically adjusted data), psoriasis patients were 18% more likely to have a COVID-19 infection compared with the general population. This finding is of importance because it suggests that patients with psoriasis should be prioritised for vaccination.

Positive effect on my Psoriasis after AstraZeneca 1st shot

Hi, I am a Canadian and just thought I would report to someone that after my AZ shot ion April 19th, within 1 month , my psoriasis, which has been arguably bad for some time on ankles , elbows and knees, ---- markedly cleared up. Usually it clears a bit across the summer, but it is better than it has been in 20 years. So I am wondering about the connection. The only other things that happened around the same time that may have contributed to improvement. 1 we got a nice dog 2 I started using a mouth piece for problematic snoring and sleep apnea So the plot thickens!!!
