BackgroundSeveral studies have shown a relationship between psoriasis and hypertension, but no meta-analysis has been restricted to studies that adjusted for confounders. The aim of the study was to estimate the association between psoriasis and hypertension with adjustment for covariates.MethodsA systematic literature search in the MEDLINE, Embase, Cochrane databases, and Google Scholar was conducted to identify relevant studies which reported the association of psoriasis with the risk of hypertension published up to November 2018 in English. Data analysis was performed with Stata V.12, and Begg adjusted rank correlation test and Egger regression asymmetry test were used to detect publication bias.ResultsA total of 16 adjusted-for-covariates studies, involving 50,291 cases with hypertension in 255,132 psoriasis patients and 76,547 cases with hypertension in 814,631 controls (no psoriasis), were included in this meta-analysis. The results indicated that psoriasis was associated with an increased risk of hypertension compared to those without psoriasis, and the prevalence of hypertension in severe psoriasis patients was higher than that in mild psoriasis patients, and the risk of hypertension in psoriasis patients was higher than that in nonpsoriasis patients in Europe and Asia.ConclusionWe conducted this meta-analysis using the adjusted-for-covariates odds ratio, demonstrating that psoriasis was associated with an increased risk of hypertension compared to those without psoriasis.
