Mutations in the cationic trypsinogen, cystic fibrosis transmembrane conductance regulator (CFTR) and pancreatic secretory trypsinogen inhibitor (PSTI) genes have recently been associated with chronic pancreatitis. This paper investigates the frequency of CFTR and PSTI gene mutation in patients with idiopathic and alcoholic chronic pancreatitis, the clinical course of patients with these two kinds of disease, and examines the clinical differences between carriers and noncarriers of mutation. In idiopathic pancreatitis a significant increase was found in mutation frequency both in the CFTR gene (13%) and N34S mutation in the PSTI gene (3.9%), as well as an increase in familial disposition to pancreatic disorders. In alcohol-induced pancreatitis an increase in calcification, exocrine insufficiency, and diabetes mellitus was observed. In conclusions, mutations in the genes investigated are involved in causing idiopathic pancreatitis. Such mutations have no connection either with the age at onset or the clinical course of the disease.

Abstract
Mutations in the cationic trypsinogen, cystic fibrosis transmembrane conductance regulator (CFTR) and pancreatic secretory trypsinogen inhibitor (PSTI) genes have recently been associated with chronic pancreatitis. This paper investigates the frequency of CFTR and PSTI gene mutation in patients with idiopathic and alcoholic chronic pancreatitis, the clinical course of patients with these two kinds of disease, and examines the clinical differences between carriers and noncarriers of mutation. In idiopathic pancreatitis a significant increase was found in mutation frequency both in the CFTR gene (13%) and N34S mutation in the PSTI gene (3.9%), as well as an increase in familial disposition to pancreatic disorders. In alcohol-induced pancreatitis an increase in calcification, exocrine insufficiency, and diabetes mellitus was observed. In conclusions, mutations in the genes investigated are involved in causing idiopathic pancreatitis. Such mutations have no connection either with the age at onset or the clinical course of the disease.File | Dimensione | Formato | |
