Psoriasis (PsO) and psoriatic arthritis (PsA) are chronic T cell-mediated inflammatory diseases that manifest not only in the skin and joints but also in the form of cardiometabolic disturbances, which include insulin resistance, dyslipidemia, and obesity. Thus, PsO and PsA patients are predisposed to metabolic syndrome (MetS), diabetes, and cardiovascular disease. In recent years, the introduction of targeted therapy in the form of tumor necrosis factor-alpha (TNF-alpha) antagonists, such as infliximab, etanercept, and adalimumab has been an important and effective addition to the treatment armamentarium for PsO and PsA. Although TNF-alpha antagonists have produced promising results clinically in reducing cutaneous and joint manifestations of PsO and PsA, their effects on MetS components in these patients are presently unclear. This review summarizes the current limited evidence on the effects of TNF-alpha antagonists on MetS components in PsO and PsA patients and extrapolates from related literature in rheumatoid arthritis, which is also a T cell-mediated inflammatory disease, for additional information.
