Lifelong Pancreatic Enzyme Replacement Therapy in Alcoholic Chronic Pancreatitis

Understanding Chronic Pancreatitis and Exocrine Insufficiency

Patients with chronic pancreatitis experience progressive and irreversible destruction of pancreatic tissue, replaced by fibrous scar tissue, leading to permanent loss of exocrine function 3
The disease results in gradual atrophy of pancreatic tissue with ductal dilation, strictures, and eventual pancreatic shrinkage and calcification, causing permanent exocrine insufficiency 3
The American Gastroenterological Association notes that chronic pancreatitis is characterized by permanent loss of both exocrine and endocrine function 1
Pancreatic exocrine insufficiency (PEI) develops as the disease progresses, resulting in maldigestion with steatorrhea (fatty diarrhea) and eventually azotorrhea (protein malabsorption) 4, 5

The European Society for Clinical Nutrition and Metabolism recommends pancreatic enzyme replacement therapy (PERT) as the gold standard treatment for PEI to reduce fat malabsorption and help achieve normal nutritional status 3
More than 80% of patients with chronic pancreatitis can be treated adequately with normal food supplemented by pancreatic enzymes, according to the European Society for Clinical Nutrition and Metabolism 5, 6
The American College of Gastroenterology notes that chronic pancreatitis causes irreversible morphological changes to the pancreas, necessitating lifelong enzyme replacement therapy 1, 3

Patients with chronic pancreatitis are at considerable risk for undernutrition, muscle depletion, and fat-soluble vitamin deficiency without proper enzyme replacement, as noted by the American Gastroenterological Association 1
The American Gastroenterological Association recommends that pancreatic enzymes be taken with meals containing normal fat content (30% of total energy intake) as the mainstay of treatment 5

Regular assessment of nutritional status and symptoms of malabsorption is necessary for long-term management, according to the European Society for Clinical Nutrition and Metabolism 4
Monitoring for vitamin deficiencies, particularly fat-soluble vitamins A, D, E, and K, is crucial in patients with chronic pancreatitis, as recommended by the European Society for Clinical Nutrition and Metabolism 5
Potential adjustments to enzyme dosage may be necessary as pancreatic function continues to deteriorate, notes the European Society for Clinical Nutrition and Metabolism 4
The American Diabetes Association notes that attention to the development of diabetes mellitus is necessary, as it occurs in 20-30% of patients with severe pancreatic insufficiency 5

Discontinuing PERT prematurely is a common pitfall, as the irreversible nature of chronic pancreatitis means that enzyme replacement must be continued lifelong, according to the American Gastroenterological Association 1, 3
Inadequate dosing of pancreatic enzymes will result in continued malabsorption and nutritional deficiencies, notes the European Society for Clinical Nutrition and Metabolism 5
Overlooking endocrine insufficiency is a common pitfall, as patients may develop type 3c (pancreatogenic) diabetes requiring insulin treatment, according to the American Gastroenterological Association 1
