In a study published online on April 14 in Arteriosclerosis, Thrombosis, and Vascular Biology, Khalid et al evaluated the risk for AAA in patients with psoriasis in a nationwide cohort study in Denmark. The study participants were Danish residents 18 years and older who were observed from January 1, 1997 until diagnosis of AAA; December 31, 2011; migration; or death. Incidence rates for AAA were calculated, and incidence rate ratios were adjusted for age, sex, comorbidity, medications, socioeconomic status, and smoking.
A total of 5,495,203 individuals were eligible for this study. Of them, Khalid et al identified 59,423 patients with mild psoriasis and 11,566 patients with severe psoriasis. The overall incidence rates of AAA were 3.72, 7.30, and 9.87 per 10,000 person-years for the reference population (23,696 cases), mild psoriasis (240 cases), and severe psoriasis (50 cases), respectively. The corresponding adjusted incidence rate ratios for AAA were increased in patients with psoriasis with incidence rate ratios of 1.20 (95% CI, 1.03-1.39) and 1.67 (95% CI, 1.21-2.32) for individuals with mild and severe disease, respectively.
Khalid et al concluded that psoriasis was associated with a disease severity–dependent increased risk for AAA; however, the mechanisms and consequences of this novel finding require further investigation.
Another example of an association of a comorbidity with psoriasis, this finding emphasizes the need for cardiovascular referral in psoriasis patients with risk factors such as hypertension and diabetes mellitus. How will these data influence your evaluation of psoriasis patients?
