PURPOSE OF REVIEW: In recent years, studies have shed light on the concept of risk heterogeneity among patients with severe hypertriglyceridemia (HTG). Several clinical risk factors for acute pancreatitis have been identified in this population, but the importance of different genetic factors above and beyond triglyceride concentration remains unclear. This review endeavours to summarize recent developments in this field.
RECENT FINDINGS: Recent studies suggest that the molecular basis of severe HTG (polygenic susceptibility vs. rare pathogenic variants) can modulate the risk of acute pancreatitis independently of triglyceride level. Furthermore, a pancreatitis polygenic risk score has been developed and validated using data from the largest GWAS meta-analysis of acute pancreatitis published to date. In patients with severe HTG, a high polygenic susceptibility for pancreatitis was associated with a three-fold increased risk of acute pancreatitis compared with those with a lower polygenic risk score.
SUMMARY: In the past months, there have been substantial advances in understanding the prediction of acute pancreatitis in patients with severe HTG. However, further efforts at developing risk-stratification strategies and predictive models may help identifying the patients who would benefit most from early and effective interventions to reduce the risk of pancreatitis, including treatment with APOC3 inhibitors.
