The proposed linkage between visfatin and insulin-induced hypertension by Oh et al may explain the linkage between exogenous insulin use and hypertension as observed in the article.1 Proinflammatory cytokines such as tumor necrosis factor α and interleukin 6 increase the expression of visfatin from visceral fat, and in return, visfatin increases the expression of peroxisome proliferator-activated receptors γ (PPARγ) and adiponectin, both of which have been shown to exert a blood pressure–lowering effect.2,3 Because Haider et al4 demonstrated that glucose-induced visfatin secretion is opposed by coinfusion of exogenous insulin in humans, it is possible that prolonged use of exogenous insulin decreases visfatin secretion and induces hypertension via a mechanism involving hyposecretion of PPARγ and adiponectin.
