If you don’t reign in inflammation, problems can arise.
The joint pain caused by psoriatic arthritis (PsA) can be brutal on its own. Some people find that it inhibits them from fully participating in life. It may be painful to engage in your usual activities, to exercise, or even to go to work or get out of bed.
However, without treatment, PsA can cause even more problems. Treatment for PsA aims not only to reduce PsA symptoms, but also to reduce the risk of complications caused by unbridled inflammation in the body.
“The body’s not meant to live in a state of continued inflammation,” says Bobby Buka, MD, dermatologist and associate clinical professor at The Mount Sinai Hospital. “It wears the body down in the joints, [and] the skin, and also some unknown areas that we may not think about.”
For example, people with psoriasis and PsA have an increased risk of depression. In general, depression is more common among people with chronic illnesses, potentially due to the stress of dealing with the illness itself. However, there’s also some evidence to suggest that depression could be linked to inflammation as well.
People with PsA are also 43 percent more likely to develop coronary artery disease than those without PsA, according to the Arthritis Foundation. That’s partially because inflammation in the body creates damage to the blood vessels.
How Treatment Can Help
Today’s treatments for PsA work to not only reduce pain, but to control inflammation. One of the most effective treatments for moderate to severe PsA is biologics, a type of disease-modifying antirheumatic drug (DMARD) that targets parts of the immune system that fuel inflammation.
PsA is an autoimmune disease, meaning the immune system—which is supposed to protect the body against external threats—is mistakenly attacking your own body. In the case of PsA, the immune system is attacking the joint space.
When the immune system is in attack mode, it releases inflammatory proteins. These inflammatory substances are what causes pain, swelling, and redness. Although researchers haven’t yet figured out how to stop the immune system from attacking the joints altogether, biologics work by eliminating those inflammatory proteins that cause damage to otherwise healthy tissue.
Biologics have two major perks: They reduce inflammation in the joints (thus reducing pain, swelling, and long-term joint damage), and they prevent complications caused by chronic inflammation in the body.
When to Talk to Your Doctor
Many people with psoriasis might ignore mild joint pain, thinking it’s tolerable or not a big deal. Even if you can “deal with” your joint pain, your body may still be suffering from the effects of untreated inflammation.
“If you have psoriatic skin disease, and you have some joints that don’t feel right, that’s psoriatic arthritis,” says Dr. Buka. “If you have marginal symptoms that you may not think are related to your psoriatic skin disease, ask your doctor about it.”

00:02.167 --> 00:05.999
I'm Doctor Bobby Buka, section chief at the Mount Sinai School of Medicine.
00:06.000 --> 00:09.999
Psoriatic arthritis is a type of arthritis that patients with psoriasis suffer from.
00:10.000 --> 00:15.232
And it affects the joint spaces, typically large joints like knees and shoulders.
00:15.233 --> 00:18.999
And it affects that synovial space, the space where two bones connect.
00:19.000 --> 00:21.799
Not everyone that has psoriasis gets psoriatic arthritis
00:21.800 --> 00:23.999
but the percentage is about 25 to 30%.
00:24.000 --> 00:27.532
Though we do know that the more severe the psoriasis is,
00:27.533 --> 00:29.999
the more likely that patient will suffer from psoriatic arthritis.
00:30.000 --> 00:31.999
If you have psoriatic skin disease,
00:32.000 --> 00:35.999
and you have some joints that don't feel right, that's psoriatic arthritis.
00:36.000 --> 00:40.399
The reason we have to get in front of psoriatic arthritis is to prevent it from progressing.
00:40.400 --> 00:43.666
All that inflammation in the synovial joint space will wear down
00:43.667 --> 00:48.699
that synovial lining and that causes a rubbing of bone to bone.
00:48.700 --> 00:53.499
So getting in front of it early means joints that will stay healthier much longer.
00:53.500 --> 00:55.432
We think psoriasis is an autoimmune condition.
00:55.433 --> 00:56.899
We know that there are two magnets:
00:56.900 --> 01:00.099
a T-cell that's part of our body's innate immune system,
01:00.100 --> 01:02.999
and an unknown antigen that that T-cell is attacking.
01:03.000 --> 01:07.132
Now, we figure that that unknown antigen is a part of our own body
01:07.133 --> 01:10.099
and that it's present more commonly in certain families,
01:10.100 --> 01:11.932
and in certain genetic makeups.
01:11.933 --> 01:13.766
What that antigen is, we haven't figure out.
01:13.767 --> 01:16.366
We know it's in the joint space, we know it's in the skin,
01:16.367 --> 01:17.999
we know it's in the coronary arteries.
01:18.000 --> 01:21.999
But what the magnet, this T-cell is attracted to, we still don't know.
01:22.000 --> 01:25.999
But it's loosely considered under the autoimmune umbrella.
01:26.000 --> 01:28.499
Autoimmune simply means that the body's attacking itself.
01:28.500 --> 01:31.966
The body's immune system has found something within ourselves
01:31.967 --> 01:35.299
that it doesn't like, that it considers external,
01:35.300 --> 01:38.999
that it considers a threat so the immune system attacks it.
01:39.000 --> 01:42.799
We wish that we could block those two magnets from colliding.
01:42.800 --> 01:45.766
We wish that we could figure out that antigen and get in the way
01:45.767 --> 01:48.999
between the T-cell and whatever it's attacking that's part of our own bodies.
01:49.000 --> 01:51.166
Right now, we're doing the next best thing.
01:51.167 --> 01:52.899
So, once those magnets collide
01:52.900 --> 01:56.666
and all these inflammatory proteins are released, we want to sponge those up.
01:56.667 --> 01:59.999
We want to get all of those inflammatory proteins out of the way
02:00.000 --> 02:03.799
so that innocent tissue doesn't get damaged in the mix.
02:03.800 --> 02:06.999
The body's not meant to live in a state of continued inflammation.
02:07.000 --> 02:09.632
And if we have these magnets connecting
02:09.633 --> 02:14.066
and we don't get in the way of treating psoriasis or psoriatic arthritis
02:14.067 --> 02:17.066
and we're living in this state of heightened immune response,
02:17.067 --> 02:18.666
it starts to wear the body down.
02:18.667 --> 02:22.466
It wears the body down in the joints, it wears the body down in the skin,
02:22.467 --> 02:24.666
and also some unknown areas that we may not think about.
02:24.667 --> 02:26.966
Like, depression is linked to psoriasis
02:26.967 --> 02:29.999
and coronary artery disease linked to psoriasis.
02:30.000 --> 02:33.899
So, it's really critical to get in the way of that inflammatory cascade
02:33.900 --> 02:36.832
and start sucking up those inflammatory mediators
02:36.833 --> 02:39.132
to prevent this heightened state of attack
02:39.133 --> 02:42.399
that's going on day to day without us even knowing it.
02:42.400 --> 02:45.899
So, if you have marginal symptoms that you may not think are related
02:45.900 --> 02:50.199
to your psoriatic skin disease, ask your doctor about it.
02:50.200 --> 02:52.467
