The adipocytokine leptin can directly induce pro\u2010inflammatory T helper 1 immune responses and the pathogenesis of chronic inflammation.

Of these patients, 267 met the inclusion criteria and were included. ELISA was used to measure circulating levels of leptin.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The VA dysfunction group had a higher leptin level than the patent VA group. A higher concentration of leptin was independently and significantly associated with an elevated risk of VA dysfunction. Multiple logistic regression analysis showed that leptin, female sex, and hypertension were independently associated with VA dysfunction, even after adjusting for known biomarkers. We then evaluated the ability of leptin, female sex, and hypertension to predict the risk of VA dysfunction, and the area under the curve (AUC) for leptin was 0.626 (<jats:italic>p<\/jats:italic>\u2009=\u20090.0001). When leptin, female sex, and hypertension were added to this multivariate model, the AUC increased to 0.679 (<jats:italic>p<\/jats:italic>\u2009=\u20090.001) for leptin and hypertension, and 0.690 for leptin, hypertension, and female sex (<jats:italic>p<\/jats:italic>\u2009=\u20090.004).
