BACKGROUND: The prevalence of metabolic diseases continues to rise worldwide, with a growing recognition of metabolic dysregulation after acute inflammatory diseases such as acute pancreatitis (AP). Adipokines and cytokines play an important role in metabolism and the course of AP, but there is a paucity of research investigating their relationship with pancreatic hormones after AP. This study aimed to explore associations between pancreatic hormones and adipokines as well as cytokines to provide insights into the pathophysiology of altered pancreatic hormone secretion following AP [corrected]. METHODS: A total of 83 patients previously diagnosed with AP and no prior diabetes or pre-diabetes were recruited into this cross-sectional follow up study. Fasting venous blood samples were collected to analyse a panel of pancreatic hormones and derivatives (amylin, C-peptide, glucagon, insulin, pancreatic polypeptide, somatostatin), adipokines (adiponectin, leptin, retinol binding protein-4, and resistin), and cytokines (interleukin-6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), and tumour necrosis factor-α (TNF-α)). Linear regression analyses were used, and potential confounders were adjusted for in multivariate analyses. RESULTS: Insulin was significantly associated with IL-6 in both unadjusted and adjusted models (p = .029 and p = .040, respectively). Amylin was significantly associated with MCP-1 in the unadjusted model (p = .046), and TNF-α in unadjusted and adjusted models (p = .025 and p = .027, respectively). CONCLUSIONS: Insulin and amylin have a strong positive association with pro-inflammatory cytokines in patients following an episode of AP. These associations have possible relevance in the development of diabetes associated with diseases of the exocrine pancreas, providing the opportunity to develop novel treatment paradigms.
