Psoriasis is a systemic disease affecting various organs; however, it is usually thought of as a skin disease. A multidisciplinary approach is needed for better outcomes. The current meta-analysis assessed the association between diabetes mellitus, high blood pressure, and psoriasis. We searched four databases, including Cochrane Library, PubMed, MEDLINE, and Google Scholar, for relevant articles using the following keywords: psoriasis, hypertension, high blood pressure, cardiovascular risk factors, and diabetes mellitus. The author's name, year, and country of publication, diabetes, and hypertension among patients with psoriasis and control subjects were collected and entered into a Microsoft Excel sheet. Out of 1209 articles retrieved, 903 articles remained after duplication removal. From the 82 full texts screened, only seven studies fulfilled the inclusion and exclusion criteria. Psoriasis was associated with diabetes and hypertension: odds ratio 1.38, 95% CI 1.17-1.64; P-value 0.0002, chi-square 224.93, and odds ratio 1.60, 95% CI 1.41-1.81, P-value 0.00001, chi-square 226.59, respectively. Substantial heterogeneity was observed (I2 for heterogeneity, 97%, P < 0.001). A broad approach is needed to address the associated comorbidities and select the appropriate therapeutic approach. Randomized controlled trials investigating the best drugs for the treatment of psoriasis and its associated cardiovascular risk factors are needed.
