Metabolic syndrome and acute pancreatitis

• The presence of metabolic syndrome portends a risk of severe acute pancreatitis.
• The presence of metabolic syndrome at admission portends a higher mortality.
• The incidence of metabolic syndrome is rising worldwide.
• We can expect higher incidence of severe acute pancreatitis in the near future.

AimThe aim of our study was to investigate the influence of metabolic syndrome on the course of acute pancreatitis determined by disease severity, the presence of local and systemic complications and survival rate.Patients and methods609 patients admitted to our hospital in the period from January 1, 2008 up to June 31, 2015 with the diagnosis of acute pancreatitis were analyzed. The diagnosis and the severity of acute pancreatitis were made according to the revised Atlanta classification criteria from 2012.ResultsOf 609 patients with acute pancreatitis, 110 fulfilled the criteria for metabolic syndrome. Patients with metabolic syndrome had statistically significantly higher incidence of moderately severe (38.2% vs. 28.5%; p = 0.05) and severe (22.7% vs. 12.8%; p = 0.01) acute pancreatitis in comparison to those without metabolic syndrome, while patients without metabolic syndrome had higher incidence of mild acute pancreatitis in comparison to those patients with metabolic syndrome (58.7% vs. 39.1%; p < 0.001). Patients with metabolic syndrome had a higher number of local and systemic complications, and higher APACHE II score in comparison to patients without metabolic syndrome. In multivariable logistic regression analysis, the presence of metabolic syndrome was independently associated with moderately severe and severe acute pancreatitis. Comparing survival rates, patients suffering from metabolic syndrome had a higher death rate compared to patients without metabolic syndrome (16% vs. 4.5%; p < 0.001).ConclusionThe presence of metabolic syndrome at admission portends a higher risk of moderately severe and severe acute pancreatitis, as well as higher mortality rate.
