What is GPP?

GPP, also known as generalized pustular psoriasis, is a chronic, rare, lifelong disease that occurs when a part of your immune system is out of balance.


What are the symptoms of GPP?

GPP symptoms can be unpredictable and include:

What do GPP flares look like?

GPP “flares” describe sudden symptoms that can intensify quickly and may become life-threatening. For many people, experiencing their first flare is how they learn they have GPP. Symptoms also continue between flares, though they may be less severe.

Symptoms on the skin can impact even a very small area and have a range of appearances:

It’s important to talk to your doctor about any symptoms you experience, no matter how severe.

If you think you may have GPP, this symptom tracker can help you document your experience so you can share with your doctor.

IL-36 Pathway.

GPP is caused by a part of the immune system called the IL-36 pathway

The IL-36 pathway helps protect the body from injury and infection. When this system is out of balance, it causes inflammation throughout the body. This inflammation then leads to GPP symptoms, both on and beneath the skin.

GPP is not the same as plaque psoriasis

While both diseases share some symptoms (like large areas of red, itchy, very dry, scaly, or cracked skin), they are different diseases caused by different pathways in the body.

GPP is a
rare
form of psoraisis

Plaque psoriasis is the
most common
form of psoraisis

GPP is more common in
women
than men

Plaque psoriasis impacts
men & women
equally

GPP is primarily
driven by the
IL-36
pathway

Plaque psoriasis
is primarily driven by the
IL-23 and IL-17
pathways

Hallmark symptoms
of GPP include
pustules and symptoms of inflammation
throughout
the body,

like fever and joint pain

Hallmark symptoms of
plaque psoriasis
include
patches of raised, inflamed,

red skin covered with

silvery-white scales

GPP flares can be
life-threatening
and require hospitalization

Plaque psoriasis
rarely requires
hospitalization

Many people may live with both diseases. It’s important to get an accurate diagnosis so your doctor can recommend the best treatment plan for your GPP.
