Effects of tumor necrosis factor α inhibitors extend beyond psoriasis: insulin sensitivity in psoriasis patients with type 2 diabetes mellitus.

Psoriasis is a chronic inflammatory disease that has been associated with an increased incidence of insulin resistance and diabetes mellitus (DM). Tumor necrosis factor (TNF) α inhibitors and IL-6 blockers, which are routinely used for the treatment of psoriasis, have been positively associated with insulin sensitivity. The aim of this study was to assess the effects of treatment with TNF-α inhibitors on insulin sensitivity in psoriatic patients with type 2 DM. This study confirms a beneficial effect of anti-TNF-α agents on insulin resistance and insulin sensitivity in psoriasis patients with type 2 DM.
