Systemic Treatment of Cutaneous Adverse Events After Immune Checkpoint Inhibitor Therapy: A Review

Dermatitis. 2021 Aug 16. doi: 10.1097/DER.0000000000000776. Online ahead of print.ABSTRACTAs treatment with immune checkpoint inhibitors (CPIs) for cancer increases, so has the incidence of immune-related cutaneous adverse events (irCAEs). These toxicities can significantly impact quality of life and may be dose-limiting. Current guidelines for irCAEs offer only corticosteroids or CPI discontinuation. Evidence supports biologic immunomodulatory therapies when corticosteroids fail or need avoidance. A review of literature from 2010 to 2020 yielded 45 articles, resulting in 185 irCAEs, including bullous pemphigoid-like eruption (n = 55), psoriasis/psoriasiform dermatitis (n = 41), and maculopapular rash (n = 31). Treatments included immunomodulators, intravenous immunoglobulin, aprepitant, acitretin, tetracyclines, and biologic agents. Overall, 92.3% of patients saw improvement or resolution of their rash. Bullous pemphigoid-like eruptions were treated with a tetracycline +/- niacinamide (94.7% success [18/19]), omalizumab (100% success [7/7]), and rituximab (100% success [10/10]). Although prospective research is required, this review provides a comprehensive list of successful, non-corticosteroid treatment options for irCAEs to improve compliance with lifesaving cancer therapy.PMID:34405836 | DOI:10.1097/DER.0000000000000776
