High hsCRP concentration is associated with acute pancreatitis in multifactorial chylomicronemia syndrome.

BACKGROUND

Multifactorial chylomicronemia syndrome (MCS) is a severe form of hypertriglyceridemia (hyperTG) associated with an increased risk of acute pancreatitis (AP). However, the risk of AP is very heterogenous in MCS. Previous studies suggested that inflammation might promote disease progression in hyperTG-induced AP.

OBJECTIVE

To determine if low-grade inflammation is associated with AP in MCS.

METHODS

This study included 102 subjects with MCS for which high-sensitivity C-reactive protein (hsCRP) concentration was measured at their first visit at the Montreal Clinical Research Institute.

RESULTS

MCS subjects with a previous history of AP had a significant higher hsCRP concentration (4.62 mg/L vs. 2.61 mg/L; p=0.003) and high hsCRP concentration (≥3mg/L) was independently associated with AP prevalence (p<0.05). Up to 64% of the variability in AP prevalence was explained by the maximal TG concentration, hsCRP concentration, the presence of rare variants in TG-related genes, and fructose intake based on a stepwise multivariate regression model (p<0.0001).

CONCLUSION

This retrospective study showed for the first time that hsCRP concentration is strongly associated with AP prevalence in MCS. It also suggests that low-grade inflammation may be a driver of AP in severe hypertriglyceridemia. Prospective studies could help determine the causality of this association and assess whether medication known to reduce low-grade inflammation could help prevent AP in individuals with severe hypertriglyceridemia.
