OBJECTIVES: The aim of our study was to describe the prevalence, characteristics, and outcomes of children with acute recurrent (ARP) or chronic (CP) pancreatitis with or without mutations in PRSS1, CFTR or SPINK1.
METHODS: Retrospective chart review of children with ARP or CP with and without testing for PRSS1, CFTR, and SPINK1. Demographics, clinical features, management, and outcome were collected. Analysis of variance was used to compare continuous variables and χ or Fisher exact test for categorical variables.
RESULTS: Ninety-one subjects with ARP (n = 77) or CP (n = 14) were identified and included in this study. Of these, 37 (41%) were male, 44 were white, and 30 were Hispanic. Thirty-three (36%) had at least 1 mutation identified (Pan-Mut): PRSS1 (7), CFTR (21), SPINK1 (3), SPINK/CFTR (2). Thirty-six were tested but had no mutation, and 22 were not tested. The Pan-Mut subjects were more likely to have a family history of pancreatitis but there were no differences in the clinical features, imaging or outcome.
CONCLUSIONS: Mutations in CFTR, SPINK1 or PRSS1 are present in one third of pediatric ARP and CP with no other cause. No clinical features or outcomes differentiated between the Pan-Mut group and the no-mutation group. The Pan-Mut subjects were more likely to have a family history of pancreatitis. Pediatric ARP and CP without identified cause should undergo genetic testing.
