Severe pancreatic exocrine insufficiency causes malabsorption, particularly steatorrhea, in chronic pancreatitis patients. Current lipase replacement therapy shows limitations, necessitating further research for improved nutrient absorption.

Area of Science:

  • Gastroenterology
  • Digestive Physiology

Background:

  • Pancreatic exocrine insufficiency (PEI) is a significant complication of chronic pancreatitis.
  • Lipase deficiency leads to malabsorption, primarily steatorrhea, due to impaired synthesis, secretion, and short intraluminal survival.

Purpose of the Study:

  • To outline current therapeutic concepts for managing malabsorption in PEI.
  • To provide recommendations for optimizing pancreatic enzyme replacement therapy (PERT).

Main Methods:

  • Review of modern therapeutic concepts for PEI management.
  • Recommendations for PERT dosage (25,000–40,000 lipase units/meal) using pH-sensitive pancreatin microspheres.
  • Emphasis on dosage titration, compliance monitoring, and differential diagnosis for treatment failure.

Main Results:

  • Standard PERT can partially normalize lipid digestion but often fails to completely resolve malabsorption.
  • Nutrient malabsorption significantly impacts patients' nutritional status and gastrointestinal function.
  • Current therapies highlight the need for improved enzymatic activity delivery.

Conclusions:

  • Effective management of malabsorption in chronic pancreatitis requires adequate intraluminal enzymatic activity.
  • Optimizing PERT dosage and ensuring patient compliance are crucial.
  • Further research and development are essential to fully normalize lipid digestion and improve patient outcomes.
