RESUMEN
BACKGROUND: Several studies stated that patient with psoriasis carried an increased risk of psoriasis but some studies did not demonstrate this association. OBJECTIVES: The aim of this study was to evaluate the prevalence of hypertension in psoriasis based on a sample of Spanish population. METHODS: This was a hospital-based case-control study involving 661 psoriatic patients (cases) and 661 control matched by gender and age. Meta-analysis of the previous studies was made. RESULTS: The prevalence of hypertension was significantly higher in psoriasis patients than controls (30.3%, 21.3%, respectively, P < 0.001). In a multivariate analysis, hypertension was associated with psoriasis after controlling for age, gender, diabetes, obesity and smoking (OR = 1.44, 95% confidence interval: 1.07-1.94). CONCLUSION: The results of this study support the association between psoriasis and hypertension.
