Pancreatitis and alcoholic pancreatitis are serious health concerns with an urgent need for effective treatment strategies. Alcohol is a known etiological factor for pancreatitis, including acute pancreatitis (AP) and chronic pancreatitis (CP). Excessive alcohol consumption induces many pathological stress responses; of particular note is endoplasmic reticulum (ER) stress and adaptive unfolded protein response (UPR). ER stress results from the accumulation of unfolded/misfolded protein in the ER and is implicated in the pathogenesis of alcoholic pancreatitis. Here, we summarize the possible mechanisms by which ER stress contributes to alcoholic pancreatitis. We also discuss potential approaches targeting ER stress and UPR in developing novel therapeutic strategies for the disease.

Background White blood cell (WBC) indices are strongly associated with cardiovascular disease, but data on the prognostic values of these parameters in patients with acute coronary syndrome (ACS) following percutaneous coronary intervention (PCI) are sparse. The current study aimed to investigate the relationship between baseline WBC indices levels and the incidence of heart failure (HF) in ACS patients after PCI and explore the predictive values over a 2-year follow-up period. Methods A total of 416 consecutive ACS patients treated with PCI were enrolled and received a median of 27.7 months follow-up. Univariate and multivariate Cox regression analyses and the receiver operating characteristic (ROC) curves were performed. Results Baseline lymphocyte (LYMPH) count, eosinophil (EO) count and eosinophil percentage (EO %) were higher in patients who experienced HF over a 2-year follow-up. In multivariate Cox proportional hazards analysis, LYMPH count, EO count and EO % were independently associated with the occurrence of HF (hazard ratio [HR] = 12.876, P = 0.025; HR = 16.625, P = 0.004; HR = 1.196, P = 0.031, respectively). The area under the ROC curve of baseline EO count predicting the occurrence of HF in ACS patients following PCI was 0.625 ( P = 0.037). For patients aged 60 years and above, who had PCI or history of coronary artery bypass grafting, the higher EO count, the higher the risk of HF. Conclusion Elevated baseline LYMPH count, EO count and EO % were independently associated with the incidence of HF in ACS patients following PCI, suggesting that WBC indices might be available, simple, and cost-efficient biomarkers with predictive value, especially for patients aged more than 60 years.
