    HOMA-estimated insulin resistance as an independent prognostic factor in patients with acute pancreatitis. Cho Seung Kook,Huh Ji Hye,Yoo Jin Sae,Kim Jae Woo,Lee Kyong Joo Scientific reports This prospective study investigated the relationship between insulin resistance assessed using the homeostatic model assessment of insulin resistance (HOMA-IR) and the prognosis of acute pancreatitis (AP). A total of 269 patients with AP were recruited in this study. HOMA-IR scores were calculated using fasting insulin and plasma glucose levels. Patients were then categorized into the non-insulin-resistant group (HOMA-IR <2.5) and the insulin-resistant group (HOMA-IR ≥2.5). We performed multivariable logistic regression analysis to investigate the independent association between IR assessed using HOMA-IR and the severity of AP. We also conducted receiver operating characteristic analysis to investigate the predictive ability of HOMA-IR for severe AP. The proportion of patients with severe AP (according to the Atlanta classification) and the percentage of ICU admissions and mortality were higher in patients with insulin resistance than in those without insulin resistance. The area under the curve (AUC) of HOMA-IR for predicting severe AP was 0.719 (95% CI 0.59-0.85, P = 0.003). This value was not significantly different from the AUCs of other AP scoring systems such as CTSI, Ranson, and BISAP. Insulin resistance was the only independent factor for either ICU admission (OR 5.95, 95% CI 1.95-18.15, P = 0.002) or severe AP (OR 6.72, 95% CI 1.34-33.62, P = 0.020). Our findings suggest that the HOMA-IR score is an independent prognostic factor in patients with acute pancreatitis. This finding indicates that insulin resistance is potentially involved in the mechanism for severe AP. 10.1038/s41598-019-51466-5
    Triglyceride and glucose (TyG) index is an effective biomarker to identify severe acute pancreatitis. Park Jin Myung,Shin Suk Pyo,Cho Seung Kook,Lee Jun Hyeok,Kim Jae Woo,Kang Chang Don,Huh Ji Hye,Lee Kyong Joo Pancreatology : official journal of the International Association of Pancreatology (IAP) ... [et al.] BACKGROUND:Early diagnosis of severe acute pancreatitis (AP) is important to reduce morbidity and mortality. We investigated the association between the triglyceride and glucose index (TyG index) and the prognosis of severe AP (SAP). METHODS:The TyG index was calculated as: ln [fasting triglycerides (mg/dL) x fasting plasma glucose (mg/dL)]/2. Multivariable logistic regression analyses were used to investigate the independent association between the TyG index and the severity of AP. RESULTS:In this study, 373 patients with AP were recruited from three hospitals. The TyG index was higher in the SAP group than in the non-SAP group. Further, the TyG index was higher than in patients admitted to an intensive care unit and those who died of AP. The TyG index was an independent predictive factor for SAP (odds ratio 7.14, 95% confidence interval 2.80-18.19). The area under the curve increased significantly, from 0.738 to 0.830, after adding the TyG index to a predictive SAP model. CONCLUSIONS:Our findings suggest that the TyG index is an independent prognostic factor in patients with AP and could be used as a simple prognostic indicator for SAP. 10.1016/j.pan.2020.09.018
