Study links psoriasis treatment and improvement in heart artery disease

Washington,
05 Feb. Researchers have found that treating psoriasis, a chronic
inflammatory skin disease,
with biologic drugs that
target immune system activity can reduce the early plaque buildup that clogs
arteries,
restricts blood flow, and leads to heart attacks and stroke.
The findings highlight how immunotherapies that treat inflammatory conditions
might play a role in the reduction of cardiovascular disease risks. The study,
funded by the United States’s National Heart, Lung, and Blood Institute
(NHLBI), part of the National Institutes of Health, appears online today in the
journal Cardiovascular Research.

“Classically a heart attack is caused by one of five risk factors: diabetes, hypertension, high cholesterol, family history, or smoking,” said Nehal N. Mehta, M.D., head of the Lab of Inflammation and Cardiometabolic Diseases at NHLBI. “Our study presents evidence that there is a sixth factor, inflammation; and that it is critical to both the development and the progression of atherosclerosis to heart attack.”

Now researchers
provided first in-human evidence that treatment of a known inflammatory
condition with biologic therapy, a type of drugs that suppresses the immune
system, was associated with a reduction in coronary artery disease, in
particular of rupture prone plaque which often leads to a heart attack.

Psoriasis
: a common skin disease in U.S.

Psoriasis, a
common skin disease affecting 3-5 percent of the U.S. population, is associated
with heightened systemic inflammation, which elevates risk of blood vessel
disease and diabetes. Inflammation occurs when the body’s defensive mechanism
kicks in to ward off infection or disease, but this mechanism can turn against
itself when triggered, for instance, by excess low-density lipoproteins (LDLs)
that seep into the lining of the arteries.

The resulting inflammatory response can cause blood clots, which block arteries and can lead to heart attack and stroke. Inflammation puts 20-30 percent of the U.S. population at risk for these kinds of events. People with inflammatory diseases such as rheumatoid arthritis, systemic lupus erythematosus, and psoriasis have a much higher rate of cardiovascular events.

Those high
rates make worse already troubling numbers: More than 15 million Americans, and
many more worldwide, suffer from atherosclerotic cardiovascular disease. Heart
attack occurs in 750,000 individuals every year in the United States; globally,
more than 7 million people had heart attacks in 2015.

The current
findings came from an observational study of the NIH Psoriasis Atherosclerosis
Cardiometabolic Initiative cohort, which had 290 psoriasis patients, 121 of
whom suffered moderate to severe skin disease and qualified for the biologic
therapy approved by the U.S. Food and Drug Administration.

For a year,
researchers followed the eligible patients, all of whom had low cardiovascular
risk, and compared them to those who elected not to receive biologic therapy.
Study results show that biologic therapy was associated with an 8 percent
reduction in coronary artery plaque.

“The
findings that intrigued us most were that coronary plaque sub-components
changed over one year, including the necrotic core and non-calcified
components, which are the culprits for most heart attacks,” Mehta said.

Prior research had linked psoriasis with premature development of high-risk coronary plaque.

Now, Mehta’s team has shown beneficial changes in this plaque when psoriasis is treated with biologic therapy – even without changes in other cardiovascular risk factors such as cholesterol, glucose, and blood pressure.

“This
appears to be an anti-inflammatory effect. In the absence of improvement in
other cardiovascular risk factors, and without adding new cholesterol
medications, patients’ soft-plaque still improved. The only change was the
severity of their skin disease,” said Mehta.

Researchers
say continued research will need to be done to confirm whether this is so, or
whether the positive effect is a result of treating the underlying inflammatory
disease.

“Our data
are observational so the next steps should be randomized, controlled trials,”
concluded Mehta.
