Plaque Psoriasis

Plaque psoriasis: An immune-mediated disease that affects nearly 1 million Canadians¹

~90% of people with psoriasis have plaque psoriasis, characterized by…

Elbow of a patient showing raised, red areas of skin. — Raised, red areas of skin covered with a silver or white layer of dead skin cells¹

Which may have more greyish, purplish, or brownish tones in people with non-Caucasian skin²

Scalp of a plaque psoriasis patient with dryness and scaling. — And can appear on any area of the body, but most often appear on the scalp, knees, elbows, trunk, and limbs¹

These plaques are often itchy and sometimes painful. Plaques in certain anatomical areas—including the face, elbows and knees, scalp, genitals, and intertriginous areas (psoriasis in areas of skin-to-skin contact)—present particular treatment challenges.¹

Canadian Survey Insights

Uncovering the impact of psoriasis symptoms

Psoriasis symptoms can range between mild, moderate, and severe. However, these symptoms aren’t just physical and can have a substantial negative emotional impact and affect quality of life as well.³

Results of a survey conducted by the Canadian Psoriasis Network and the Canadian Association of Psoriasis Patients*^,4

When asked to select all the personal attributes experienced over the past few years, respondents selected the following attributes the most:

Negative effect
on daily life

Lack of
self-esteem

Interrupted or
lost sleep

Anxiety

Depression

Avoiding intimacy

*The Journey to Stability Survey was open from September 15 to November 8, 2017. Online surveys were completed by 286 English and 36 French respondents, with the majority (96.5%) being adults living with psoriasis. The survey findings only represent the experiences of Canadians who responded. There was no accompanying educational material provided to respondents, so any limitations in their own knowledge (e.g. about new treatments like biologics or biosimilars) were not addressed. In addition, sample bias is possible as people dealing with issues related to their psoriasis may be more apt to respond to such a survey rather than people who have achieved greater control over their condition.
