Factors predicting persistence of biologic drugs in psoriasis: a systematic review and meta-analysis.

Our meta-analysis demonstrates that female sex and obesity predict biologic discontinuation, and concomitant psoriatic arthritis predicts biologic survival. What's already known about this topic? Ineffectiveness is the main factor that causes drug discontinuation during long-term treatment of psoriasis. It is unclear which factors and comorbidities impact drug persistence. What does this study add? Female sex and obesity predict biologic discontinuation due to ineffectiveness and adverse events. Concomitant psoriatic arthritis is associated with improved drug persistence.
