Advances in Psoriasis

Abstract

Emerging evidence demonstrates that patients with psoriasis are more likely to suffer from hypertension, dyslipidaemia, obesity, diabetes, cardiovascular disease, stroke and atrial fibrillation. The relationship between psoriasis and these diseases is complicated by multiple confounder variables including diet, exercise, alcohol and smoking which differ between the general population and patients with psoriasis. Psoriasis is a disease of chronic systemic inflammation and it is increasingly clear that inflammation plays a pivotal role in the pathogenesis of cardiovascular disease, hypertension, diabetes and obesity. This provides a mechanism by which psoriasis may confer an additional risk of these comorbidities.

Patients with psoriasis are also at an increased risk of experiencing psychiatric illness (particularly depression) and malignancy. The nature of this relationship remains to be determined. Genome wide association studies have identified that patients with psoriasis have an increased risk of developing diseases associated with immune dysfunction (e.g. ulcerative colitis) and autoimmune disease (e.g. type 1 diabetes).

Recognition of comorbid disease is of great importance as this may affect treatment choice, treatment efficacy, morbidity and mortality.
