Psoriasis is a chronic disease
of your immune system that causes cells to build up on the surface of your
skin, leading to thick, red, scaly patches that are very itchy and sometimes
painful. Up to 7.5 million Americans suffer from the disease, which has a
surprisingly significant economic impact as well.
A new study in JAMA
Dermatology reported that direct US healthcare costs related to psoriasis may
be up to $63 billion a year.1 There were also indirect costs (such as loss of
work hours) of up to $35 billion and another $35 billion in costs related to
associated health problems, like heart disease and depression.
Taken together, the
researchers found the annual US cost of psoriasis amounted to approximately
$112 billion in 2013.
Psoriasis Is More Than a Superficial
Skin Condition
Although psoriasis appears as
a skin condition, it is actually an autoimmune disease. Part of the reaction
occurs when a type of white blood cell called a T cell mistakenly attacks
healthy skin cells.
These overactive T cells then
trigger other immune responses that collectively speed up the growth cycle of
skin cells, causing them to move to the outermost layer of your skin in a
matter of days rather than weeks.
Because the dead skin cannot
be removed quickly enough, it builds up into the thick patches characteristic
of psoriasis. For up to 60 percent of people with psoriasis, the condition
seriously impacts their daily life.
Your skin may become so
inflamed that it cracks and bleeds. Up to 30 percent of sufferers also develop
psoriatic arthritis, which can cause debilitating joint damage.
People with psoriasis are also
at an increased risk of numerous other chronic diseases, including eye
conditions, type 2 diabetes, high blood pressure and heart disease. And then
there is the psychological repercussions.2
Those who aren’t familiar with
psoriasis may view it as a contagious rash, and as a result people with
psoriasis may be shunned or excluded socially. People with psoriasis often
suffer from depression, low self-esteem, social isolation and problems at work,
which may lead to a lower income.3
