OBJECTIVES: Mutations in the secretory trypsin inhibitor (SPINK1) gene have been found to be associated with hereditary and chronic pancreatitis. There are no previous reports on SPINK1 mutations in patients with acute pancreatitis (AP). METHODS: The study population consists of 371 patients with AP, of which 207 patients had mild and 164 had a severe form of the disease. The etiologies of AP were identified. Four hundred fifty-nine blood donors served as controls. SPINK1 N34S and P55S mutations were detected by minisequencing and confirmed by direct sequencing. RESULTS: The N34S mutation was found in 29 (7.8%) of the patients and in 12 (2.6%) of the controls (P < 0.0001, Fisher exact test). There was no difference in the frequency of the P55SS mutation between the groups. A majority of the patients (n = 229; 61.7%) had alcohol-induced AP. The frequency of the N34S mutation was higher in the subgroups of severe AP (15/164; 9.1%) and alcohol-induced AP (21/229; 9.2%), but the differences were not statistically significant. No differences in age at admission and number of attacks of AP were observed between the groups. CONCLUSION: SPINK1 N34S mutation enhances the susceptibility of AP.
