The biologic guidelines noted that, while FDA-approved biologics were deemed safe overall for patients with moderate to severe psoriasis, dermatologists should recognize the adverse effects of these therapies, monitor for infections, and counsel their patients against modifying or discontinuing therapy without first consulting a dermatologist. In general, the working group noted that failure with one biologic does not necessarily mean that a patient will experience failure with a different biologic, even among TNF-alpha and IL-12/IL-23 inhibitors. However, reduced efficacy for a patient receiving a specific TNF-alpha inhibitor may predict reduced efficacy when switching to a different TNF-alpha inhibitor, they said.
In the psoriasis comorbidity guideline, the working group examined the therapeutic interventions for psoriasis-related comorbidities such as psoriatic arthritis (PsA), cardiovascular disease, metabolic syndrome, and inflammatory bowel disease. They also provided recommendations on the effect of psoriasis on mental health, quality of life, and lifestyle choices such as smoking and alcohol use.
With respect to cardiovascular disease, the dermatologist should ensure that patients are aware of the association between risk factors for cardiovascular disease and psoriasis, and that they undergo screening for these risk factors, consider lifestyle changes to reduce risk of cardiovascular disease, and consult with cardiologists and primary care providers based on individual risk, the guideline states. The working group recommended that patients with psoriasis undergo screening for hypertension, diabetes, and hyperlipidemia based on national guidelines, with more frequent screening recommended for patients with psoriasis greater than 10% body surface area or who are eligible for systemic or phototherapy.
