Understanding Psoriasis:  Symptoms and Treatment with Medication

More than 8 million Americans have psoriasis, according to the National Psoriasis Foundation.  Between 10-30% of these people will develop psoriatic arthritis.

Psoriasis is a chronic autoimmune condition that may be genetic.  It is a systemic inflammatory disease, but it is still not fully known what the single cause of the development of psoriasis is.  The American Academy of Dermatology Association (AAD) states “When a person has psoriasis, something goes wrong in the immune system, so T-cells also attack the body’s skin cells. This attack causes the body to make new skin cells more often. The extra skin cells pile up on the surface of the skin, and you see psoriasis.”

Facts about psoriasis from the American Academy of Dermatology Association (AAD) 

  • Psoriasis is not contagious
  • Psoriasis occurs in all races and genders

What are the symptoms of Psoriasis?

Raised, inflamed, itchy, bumpy, red skin with silvery or white scales is the obvious symptom of psoriasis.

Psoriasis can occur anywhere on the body, including the legs and torso, but the most common areas are the elbows, hands and knees.

What are the different types of Psoriasis?

Plaque Psoriasis – This is the most common form, with symptoms that include raised, red patches of skin with silvery and white scales of skin.

Guttate Psoriasis – This form of psoriasis often appears after a strep infection.  Symptoms include small lesions that look like little dots.  It is the second most common form of psoriasis, affecting about 10% of those with psoriasis.

Inverse Psoriasis – This form of psoriasis appears as dark red lesions in the folds of the body such as the armpit, behind the knee or in the groin.

Pustular Psoriasis – This form of psoriasis is characterized by little white blisters or pustules containing pus. It is not contagious, and usually appears on the hands and/or feet.

Erythrodermic Psoriasis – This severe form of psoriasis can be life-threatening.  It is a widespread, very red, itchy and painful psoriasis which may cause skin to come off the body.  While it is rare, it occurs in approximately 3% of those who have unstable plaque psoriasis.

What is Psoriatic Arthritis (PsA)?

30%of individuals with psoriasis have psoriatic arthritis.  Psoriatic arthritis is a chronic, inflammatory disease affecting the joints and locations where ligaments and tendons attach to the bones. Left untreated this disease can cause permanent joint damage resulting in a loss of range of motion.   Patients suspected of having PsA will most often be referred to a rheumatologist to find an effective treatment plan.

What can cause Psoriasis to appear?

Certain conditions may cause psoriasis to appear for the first time or cause existing psoriasis to flare up. Some known triggers of psoriasis include:

  • Stress
  • Cold, dry weather
  • Strep throat or other infections
  • Bad sunburns and other skin injuries
  • Certain medications such as prednisone,  hydroxychloroquine, or lithium
  • Tobacco and alcohol use

How is psoriasis diagnosed?

Your doctor will be able to tell you if you have psoriasis. However, often doctors will refer patients with skin conditions to a certified dermatologist, who will create a full range treatment plan to help manage and treat your psoriasis and help prevent uncomfortable flare-ups.

During an examination your doctor or dermatologist will examine your symptoms and ask about other related symptoms such as joint pain and/or swelling.  They will often ask if any other members of your family have this condition and if you have recently had any stress or illnesses.  Often a small sample of skin is removed for examination to determine and confirm if you have psoriasis.

How is Psoriasis treated?

Psoriasis is treated according to several factors, including:

  • Severity
  • Location on the body
  • Type of psoriasis
  • Other medical conditions you may have
  • Other medications you may be taking.
