C-reactive protein -717C>T genetic polymorphism associates with esophagectomy-induced stress hyperglycemia.

BACKGROUND: Stress hyperglycemia refers to the transient hyperglycemia seen during illness and is usually restricted to patients without previous evidence of diabetes. The influence of genetics on surgery-induced hyperglycemia remains only partially understood. METHODS: The study participants were Japanese patients treated for thoracic esophageal cancer with curative esophagectomy at Akita University Hospital between 2003 and 2007. We determined the associations between esophagectomy-induced stress hyperglycemia (> or =30 mg/dl increases in blood glucose during surgery) and genetic polymorphisms for C-reactive protein (CRP), tumor necrosis factor (TNF)-alpha, -beta, interferon-gamma, transforming growth factor-beta1, interleukin (IL)-1beta, IL-2, IL-4, IL-6, IL-6 receptors, IL-10, IL-12beta, adiponectin, and peroxisome proliferator-activated receptor-gamma. RESULTS: In 28 (46%) patients, blood glucose levels increased more than 30 mg/dl during surgery. Among the genetic polymorphisms tested, CRP -717C>T was significantly associated with stress hyperglycemia during esophagectomy. Multivariate logistic regression revealed that patients with the CRP -717T/T genotype had a significantly greater risk of developing surgery-induced hyperglycemia than those with the CRP -717C/T genotype. Stress hyperglycemia was also significantly associated with postoperative infectious complications and duration of intensive care unit stay. CONCLUSIONS: It is suggested that CRP -717 C>T genetic polymorphism may be a predictive factor for stress hyperglycemia in patients receiving esophagectomy for thoracic esophageal cancer.[1]
