What is GPP? Generalized Pustular Psoriasis, or GPP, is a rare, neutrophilic skin disease characterized by episodes of widespread eruption of sterile, macroscopically visible pustules and erythematous skin that can occur with or without systemic inflammation.
00:37.000 - 00:47.129
The mean age of disease onset is approximately 40 years, and most studies show that the ratio of GPP in females compared to males is close to 2:1.
00:47.258 - 01:00.690
Numerous GPP triggers have been identified, including upper respiratory infections, sudden withdrawal of steroids, certain medications, stress, infections, exposure to sunlight, and pregnancy.
01:00.836 - 01:17.409
A range of comorbidities have been associated with GPP, including metabolic comorbidities, like hypertension, hyperlipidemia, and diabetes mellitus, hepatic comorbidities, such as fatty liver, and cardiovascular comorbidities, such as ischemic heart disease.
01:18.027 - 01:22.849
The differential diagnosis for GPP can include numerous other pustular skin diseases.
01:23.000 - 01:26.489
How does GPP differ from plaque psoriasis?
01:27.254 - 01:41.871
Clinical manifestations of GPP can vary, but can include both skin symptoms, such as pain, itching and burning, as well as systemic signs and symptoms, like fever, swelling, malaise, joint pain, headache, and leukocytosis.
01:42.052 - 01:59.003
GPP also differs from plaque psoriasis in its pathogenesis. GPP is characterized by innate immune inflammation and is considered a neutrophilic disease, whereas plaque psoriasis is characterized by adaptive immune responses and is considered an autoimmune disease.
01:59.432 - 02:13.476
GPP places a burden on patients and can have substantial impact on their social relationships and mental health. Skin scaling, lesions, and constant itch can create social stigma for patients during a flare.

00:02.057 --> 00:05.051
[Kate] When I wake up and I think I'm having a flare up,
00:05.051 --> 00:06.738
my stomach just drops right out.
00:06.738 --> 00:09.157
It's like this feeling of impending doom.
00:12.030 --> 00:13.424
You almost go through the stages of grief.
00:13.424 --> 00:17.828
It's like, oh, what happens now? Do I have to miss work? How much work?
00:19.575 --> 00:22.294
My name is Kate and I'm autistic.
00:22.377 --> 00:27.186
I'm disabled and I have generalized pustular psoriasis.
00:27.337 --> 00:32.883
[Generalized pustular psoriasis (GPP) is a rare, lifelong disease.]
00:33.131 --> 00:36.686
[GPP flares can happen repeatedly and come on very suddenly.]
00:36.711 --> 00:41.008
So it starts for me like redness and then it gets,
00:42.081 --> 00:45.493
it feels like your skin is so sensitive that anything to touch it hurts.
00:45.493 --> 00:47.190
So it hurts to wear clothing.
00:48.616 --> 00:50.515
And when I was in the hospital, I just had –
00:50.515 --> 00:52.915
it was all up my arms all the way to my hands.
00:52.915 --> 00:56.415
And it was my face, my scalp,
00:57.981 --> 01:00.768
it was like the worst itch of my entire life.
01:01.166 --> 01:04.390
But if I scratched it, it was like agony.
01:04.390 --> 01:05.895
It was like if you itched something
01:05.895 --> 01:07.480
and then realized you’re itching a wound.
01:10.477 --> 01:12.106
It's always tiring being disabled.
01:12.106 --> 01:13.036
There's no getting around that.
01:13.036 --> 01:16.030
I'm tired a lot, and,
01:16.030 --> 01:19.100
just the amount of things I have to worry about in my day
01:19.100 --> 01:21.893
that people kind of take for granted as they move through the world.
01:22.290 --> 01:23.898
It's a reality for a lot of us.
01:23.898 --> 01:27.062
There's a lot of us who are disabled and it's, it's not something
01:27.062 --> 01:30.327
you ever get the-- you ever get to stop thinking about.
01:33.198 --> 01:35.749
The world makes me really sad sometimes
01:35.749 --> 01:39.072
and the only thing that helps is helping other people.
01:39.648 --> 01:41.731
That's why I love working with kids,
01:41.731 --> 01:45.433
because I can tell them, “You are great and wonderful, whoever you are.”
01:46.176 --> 01:49.203
I'm a librarian and I have been for a long time.
01:49.203 --> 01:51.834
We get to do the helping, which always makes me happy.
01:52.293 --> 01:55.180
I run a website for kids in my spare time
01:55.180 --> 01:57.831
and I just get to do really beautiful things.
01:59.544 --> 02:00.997
You know, when you're disabled
02:00.997 --> 02:03.439
you don't have the luxury of being medium at your job.
02:03.439 --> 02:06.079
One of my friends calls it the disability tax,
02:06.460 --> 02:09.266
the extra effort that goes into everything.
02:09.910 --> 02:12.609
And I think that employers have this feeling that,
02:12.609 --> 02:14.857
that takes away from the work we're able to offer.
02:15.215 --> 02:17.507
But no, we work so hard.
02:23.180 --> 02:25.406
You know, I’m very optimistic now.
02:25.406 --> 02:26.745
I have to be optimistic.
02:26.883 --> 02:32.012
Because I've really been able to calibrate my life around my needs in a new way.
02:32.829 --> 02:35.629
I have, you know, I have money because I need it to live.
02:35.629 --> 02:40.101
But I mean, my job is also my passion and I'm really lucky there.
02:41.798 --> 02:47.001
I have-- my life is full. It's, it's a beautiful life.
02:49.220 --> 02:56.138

[Diagnosis and journey]
[Carlie] I was diagnosed in 2011, and it was a long, scary thing.
00:09.548 --> 00:18.000
I went to a dermatologist to complain about my skin, and I told him that
00:18.000 --> 00:20.617
I had psoriasis and he said, “No, you do not.”
00:20.617 --> 00:21.634
So I went
00:21.634 --> 00:27.541
back to my rheumatologist because I was in pain quite a bit and didn’t know why.
00:27.541 --> 00:32.198
And he really didn’t know why until I saw a new doctor.
00:33.023 --> 00:35.983
It’s like a lightbulb went off in his head, and he said, “Oh my goodness,
00:35.983 --> 00:40.028
I think I know what’s wrong. I think you have GPP.”
00:40.028 --> 00:42.166
I feel that there’s a lot of need
00:42.166 --> 00:47.000
for dermatologists to understand that there’s more than one kind of psoriasis
00:47.000 --> 00:51.950
besides plaque psoriasis, so that we can get the help that we need.
00:52.880 --> 01:00.596
[Flares and between flares]
I have flares about it seems like every few months. Right now, I’ve been in a flare
01:00.596 --> 01:04.358
for like the last 6 months because I’ve been under a lot of stress.
01:05.996 --> 01:08.783
The flares affect my daily life
01:11.474 --> 01:15.349
in every way. They affect me emotionally, mentally, physically.
01:15.349 --> 01:18.480
It affects the people surrounding me
01:20.603 --> 01:26.748
in every way possible. I have to figure out what to wear, because I often bleed.
01:27.770 --> 01:30.413
The material sticks to my skin.
01:31.246 --> 01:34.000
I’m embarrassed by the scars on my arms
01:34.330 --> 01:38.000
so I tend to not want to get in relationships.
01:38.700 --> 01:43.190
The flares affect me with my fatigue — I’m tired all the time,
01:43.193 --> 01:46.080
so often I have to cancel out on plans.
01:46.084 --> 01:50.300
People don’t understand that suddenly I don’t feel good.
01:50.324 --> 01:52.882
I might have fever, I have to go to the hospital.
01:53.736 --> 01:58.091
It’s a lot on a daily basis to handle, mentally and physically.
01:59.472 --> 02:05.574
[Living with GPP]
The tips that I would recommend to people to help manage their would be number one,
02:05.574 --> 02:11.196
to get lots of rest. Recognize your symptoms. That if you’re itching and burning
02:11.196 --> 02:15.856
and you get blisters that are pus-filled, go to the doctor. Don’t wait.
02:16.950 --> 02:19.400
I would say try not to be hard on yourself.
02:19.400 --> 02:21.520
That’s the biggest advice that I can give.
