A Case of Erythrodermic Psoriasis Successfully Treated With Ixekizumab Combined With Low-Dose Methotrexate to Ensure Sustained Clearance: A Case Report.

Erythrodermic psoriasis (EP) is a severe type of psoriasis that requires immediate and effective treatment to prevent serious complications. Although recommended as first-line treatment for EP, conventional systemic disease-modifying antirheumatic drugs (csDMARDs) such as methotrexate and/or cyclosporine can sometimes be ineffective or undesirable, hence the use of biologics. However, in cases of refractory disease, biologics may be combined with methotrexate to boost efficacy and optimize outcomes without compromising safety and tolerability.
