Hereditary chronic pancreatitis (HCP) is a rare, early-onset condition. PRSS1 gene mutations are causative, leading to similar symptoms and treatments as other chronic pancreatitis forms.

Area of Science:

  • Gastroenterology
  • Genetics
  • Pancreatology

Background:

  • Hereditary chronic pancreatitis (HCP) is a rare, early-onset form of chronic pancreatitis.
  • Its clinical course, morphology, and lab findings are similar to alcoholic chronic pancreatitis.
  • Symptoms include abdominal pain, pancreatic dysfunction, diabetes, and potential complications like pseudocysts and cancer.

Purpose of the Study:

  • To describe the characteristics, genetic basis, and management of hereditary chronic pancreatitis.
  • To highlight the role of PRSS1 gene mutations in HCP pathogenesis.
  • To emphasize the need for genetic testing in selected patients and risk factor avoidance.

Main Methods:

  • Review of clinical, morphological, and laboratory findings in HCP patients.

  • Analysis of genetic mutations, particularly in the PRSS1 gene.
  • Discussion of diagnostic criteria, treatment strategies, and prognosis.

    • Main Results:

    • PRSS1 gene mutations, encoding cationic trypsinogen, are causative in HCP.
    • Mutations lead to increased trypsinogen activation and protease imbalance.
    • Other genes (PRSS2, SPINK1, CFTR) are also associated with chronic pancreatitis.
    • HCP patients have an elevated risk of pancreatic cancer.

    Conclusions:

    • HCP diagnosis and treatment resemble other chronic pancreatitis types.
    • Genetic testing via DNA sequencing is recommended for select patients.
    • Management involves enzyme/nutritional support, pain control, and complication management.
    • Patients should avoid environmental risk factors for pancreatic cancer due to elevated risk.
