Things worth knowing about "Pancreatic Enzyme Replacement Therapy"

Pancreatic enzyme replacement therapy (PERT) supplies digestive enzymes when the pancreas can no longer produce enough. It improves nutrient absorption and relieves symptoms such as fatty stools and weight loss.

What is Pancreatic Enzyme Replacement Therapy?

Pancreatic enzyme replacement therapy (PERT) is a medical treatment in which artificially supplied digestive enzymes compensate for the reduced or absent natural enzyme production of the pancreas. It is indicated when the pancreas can no longer produce sufficient enzymes to fully break down and absorb nutrients from food – a condition known as exocrine pancreatic insufficiency (EPI).

Causes of Exocrine Pancreatic Insufficiency

Several underlying conditions can make pancreatic enzyme replacement therapy necessary:

Chronic pancreatitis: Long-term inflammation of the pancreas, often caused by alcohol or gallstones
Cystic fibrosis: A genetic disorder associated with markedly reduced enzyme secretion
Pancreatic cancer: Destruction of glandular tissue by malignant disease
Pancreatic surgery: Partial or total removal of the pancreas (e.g., Whipple procedure)
Type 3c diabetes mellitus: Pancreatogenic diabetes resulting from pancreatic disease

Symptoms of Exocrine Pancreatic Insufficiency

Without adequate enzyme activity, fats, proteins, and carbohydrates cannot be properly digested. Common symptoms include:

Fatty, foul-smelling stools (steatorrhoea)
Diarrhoea and bloating
Unintentional weight loss
Malnutrition and vitamin deficiencies (especially fat-soluble vitamins A, D, E, and K)
Abdominal pain and cramping after meals
Muscle weakness and general fatigue

Diagnosis

Several tests are used to confirm exocrine pancreatic insufficiency:

Faecal elastase-1 test: Measures the enzyme elastase in stool – low levels indicate insufficiency
72-hour faecal fat test: Directly quantifies fat loss in stool
Imaging studies: Ultrasound, CT, or MRI to assess pancreatic tissue
Breath tests: Such as the ¹³C-mixed triglyceride breath test for functional assessment

Mechanism of Action

PERT preparations typically contain pancreatin, a mixture of digestive enzymes derived from animal sources (usually porcine, i.e., from pigs):

Lipases: Break down fats into fatty acids and glycerol
Amylases: Digest carbohydrates (starches)
Proteases: Break down protein molecules into amino acids

Most preparations are formulated as enteric-coated microspheres or minitablets enclosed in gelatin capsules. This coating protects the enzymes from stomach acid and ensures they are released only in the small intestine, where digestion takes place.

Dosage and Administration

Enzyme dosage is based on the fat content of the meal and the individual severity of insufficiency. General recommendations include:

Enzymes should be taken at the start of a meal or distributed throughout the meal
For main meals, 25,000–80,000 lipase units are typically recommended
Smaller doses (e.g., 10,000–25,000 units) are usually sufficient for snacks
Capsules should not be chewed; the contents may be sprinkled onto soft food if needed
Dosing is individualised and monitored by a physician

Side Effects

Pancreatic enzyme preparations are generally well tolerated. Possible side effects include:

Nausea, vomiting, or abdominal pain (usually with excessive dosing)
Diarrhoea or constipation
Skin reactions (rare, in cases of hypersensitivity to porcine proteins)
At very high doses: fibrosing colonopathy (scarring of the colon) – primarily reported in children with cystic fibrosis
Elevated uric acid levels with prolonged high-dose therapy

Treatment Success and Quality of Life

With correctly adjusted PERT, most patients experience a significant improvement in symptoms. Weight gain, normalisation of bowel movements, and resolution of vitamin deficiencies are typical signs of treatment success. Regular follow-up (blood counts, vitamin levels, body weight) is important to optimise therapy over time.
