Pancreatitis has the potential to occur with increasing cases of hyperlipidemia and alcohol consumption. Meanwhile, until now pharmacotherapy for pancreatitis is more emphasized for pain relief and lowering triglyceride levels (for HFD-induced pancreatitis). The polyphenol (quercetin) has several biological activities, including anti-cancer, antiallergic, anti-inflammatory and ant-diabetic. This study aimed to evaluate the potential effect of quercetin to treat pancreatitis. After verification, 19 relevant articles were included in the analysis, where Linear mix model analysis was applied to parameters including blood glucose, pancreas islet number, insulin level, TBARS level, nuclear factor kappa B (NF-κB), endogenous antioxidant (GSH, SOD, CAT, GPx), TNFα, IL−6, Caspase 3 (Casp3) and IL−1b gene expression. The level quercetin was used as fixed effect and study setting as random effect. The administration of quercetin was able to significantly increase the production of tissue insulin, restore the antioxidant defense system (increase SOD, GSH, decrease TBARS), and inhibit the progression of inflammation based on the expression of NF-kB, TNFα and IL−6 genes. Therefore, the results of meta-analysis support the hypothesis that quercetin is able to restore pancreatic function, and has the potential to be developed to treat pancreatitis.
