There is a growing amount of literature demonstrating that psoriasis is a chronic and debilitating inflammatory disease associated with serious comorbidities. Emerging comorbidities of psoriasis include cardiovascular disease and metabolic syndrome. Psoriasis patients have an increased prevalence of the core components of metabolic syndrome, including obesity, dyslipidemia, and insulin resistance.
According to van der Voort et al (J Am Acad Dermatol. 2014;70:517-524), prior case-controlled studies observed an increased prevalence of nonalcoholic fatty liver disease (NAFLD) in patients with psoriasis, which they noted as a relevant factor in selecting optimal psoriasis treatment. Their study sought to compare the prevalence of NAFLD in participants with psoriasis and those without psoriasis. They conducted a large prospective population-based cohort study that enrolled elderly participants (>55 years). Nonalcoholic fatty liver disease was diagnosed as fatty liver on ultrasonography in the absence of other liver diseases. A multivariable logistic regression model was used to assess if psoriasis was associated with NAFLD after adjusting for demographic and lifestyle characteristics as well as laboratory findings.
In total, 2292 participants were included in the study; 118 (5.1%) participants had psoriasis. The prevalence of NAFLD was 46.2% in participants with psoriasis compared to 33.3% in those without psoriasis (P=.005); psoriasis was significantly associated with NAFLD. After the authors adjusted for alcohol consumption, pack-years and smoking status, presence of metabolic syndrome, and alanine aminotransferase levels, psoriasis remained a significant predictor of NAFLD (adjusted odds ratio, 1.7; 95% confidence interval, 1.1-2.6). The authors concluded that elderly participants with psoriasis were 70% more likely to have NAFLD than those without psoriasis independent of common NAFLD risk factors.
What’s the issue?
This study gives us a new comorbidity to be aware of and monitor. In considering therapy in this population, it also is important to consider the risk for NAFLD when selecting treatments that may have hepatic toxicity or are metabolized by the liver. How will this study change your approach to patients with psoriasis?
