OBJECTIVE
The etiology of acute pancreatitis (AP) seems to have changed during the last two decades, and since detection of mutations in the gene for cationic trypsinogen(PRSS1) causing hereditary pancreatitis some patients formerly diagnosed with idiopathic AP (IAP) turn out to have a genetic cause.
METHODS
Data on patients <30 years of age, diagnosed with AP identified in the Danish National Registry of Patients, were retrieved. Patients previously diagnosed with IAP were offered genetic counseling and testing for mutations in the PRSS1, the Serine Protease Inhibitor Kazal type1 (SPINK1) and the Cystic Fibrosis Transmembrane Conductance Regulator gene (CFTR).
RESULTS
The standardized incidence ratio (SIR) of AP increased from 3.56 per 100,000 person-years in the period 1980-1984 to 6.43 in 2000-2004 (p < 0.01). The SIR of women surpassed that of men in 1999. Among patients with former IAP, 3 had hereditary pancreatitis, 3 CFTR and 4 SPINK1 mutations after re-evaluation.
CONCLUSIONS
The incidence of AP, especially in women, increased over time. More patients had gallstone-related and less alcohol-related AP in the period 1999-2004 compared to 1980-1999. Genetic causes of AP were found in 32% of those tested with IAP and as a minimum estimation in 4% of the total cohort. and IAP.
