Hereditary pancreatitis for the endoscopist

Area of Science:

• Genetics
• Gastroenterology
• Hereditary Diseases

Background:

• Hereditary pancreatitis shares features with alcoholic pancreatitis but typically manifests earlier.
• It is primarily associated with mutations in the serine protease 1 (PRSS1) gene, encoding cationic trypsinogen, accounting for most cases.
• Other genetic factors include SPINK1 and CFTR mutations.

Purpose of the Study:

• To review hereditary pancreatitis, its genetic basis, clinical presentation, and management.
• To discuss diagnostic criteria, including genetic testing and family history.
• To highlight the increased risk of pancreatic carcinoma and outline treatment strategies.

Main Methods:

• Review of existing literature on hereditary pancreatitis.
• Analysis of genetic mutations (PRSS1, SPINK1, CFTR) associated with the condition.
• Compilation of clinical features, diagnostic approaches, and treatment modalities.

Main Results:

• PRSS1 mutations are found in 68-81% of hereditary pancreatitis cases.
• Symptoms can appear in the first or second decade of life, significantly earlier than alcoholic pancreatitis.
• Patients face recurrent acute pancreatitis, potential exocrine/endocrine insufficiency, and a markedly increased risk of pancreatic cancer.

Conclusions:

• Hereditary pancreatitis requires early diagnosis through genetic testing or family history.
• Management involves enzyme and nutritional support, diabetes care, pain palliation, and avoidance of alcohol and tobacco.
• Genetic counseling and testing are recommended for affected families due to the elevated cancer risk.
