The more severe the psoriasis, the greater likelihood of uncontrolled hypertension, according to data from a population-based study. The findings were published online Oct. 15 in JAMA Dermatology.
In patients with diagnosed hypertension, those with moderate to severe psoriasis showed a positive dose-response relationship between their psoriasis activity and high blood pressure, wrote Dr. Junko Takeshita of the University of Pennsylvania, Philadelphia, and her associates (JAMA Dermatol. 2014 Oct. 15 [doi:10.1001/jamadermatol.2014.2094]).
The researchers compared a random sample of 1,322 adults aged 25-64 years with psoriasis and hypertension and 11,977 age- and practice-matched controls with hypertension. The data were taken from a population-based, cross-sectional study nested in a prospective cohort drawn from an electronic medical records database in the United Kingdom.
After investigators adjusted for age, sex, body mass index, smoking and alcohol use status, presence of comorbid conditions, and current use of antihypertensive medications and nonsteroidal anti-inflammatory drugs, they found psoriasis activity and uncontrolled hypertension correlated, with adjusted odds ratios of 0.97 for mild psoriasis,1.20 for moderate psoriasis, and 1.48 for severe psoriasis (P = .01). The likelihood of uncontrolled hypertension among psoriasis overall was also increased, but this increase was not statistically significant.
The study was limited by its cross-sectional design, which make the directionality of the two conditions hard to determine, the researchers noted.
However, the findings suggest that, among patients with hypertension, psoriasis “is independently associated with poorly controlled blood pressure,” and that more effective blood pressure management is warranted in psoriasis patients, especially those with more severe disease.
Dr. Takeshita reported receipt of payment for continuing medical education work related to psoriasis. Coauthor Dr. Joel Gelfand reported serving as a consultant for AbbVie, Amgen, Celgene, Eli Lilly, Janssen Biologics, and others. This study was supported in part by the National Heart, Lung, and Blood Institute and the National Institute of Arthritis and Musculoskeletal and Skin Diseases.
