From the Guidelines
Glucagon plays a crucial role in maintaining blood glucose levels in pancreatic insufficiency, and its abnormalities can contribute to glucose metabolism disturbances, making it essential to monitor and manage glucagon levels in patients with pancreatic insufficiency. In pancreatic insufficiency, the pancreas cannot produce enough digestive enzymes and may have impaired hormone production, including glucagon. Patients with pancreatic insufficiency may experience altered glucagon secretion, which can manifest as postprandial hypoglycemia due to inadequate glucagon response or, conversely, hyperglycemia from relative excess of glucagon compared to insulin 1.
Management of Glucagon Abnormalities
Management typically focuses on treating the underlying pancreatic condition with pancreatic enzyme replacement therapy (PERT) such as pancrelipase (typical starting dose 500 lipase units/kg/meal). For patients experiencing hypoglycemic episodes, glucagon emergency kits (1 mg for adults) should be prescribed, and patients and caregivers should be educated on their use 1. Small, frequent meals with complex carbohydrates can help stabilize blood glucose levels. Regular monitoring of blood glucose is essential, and patients should work with endocrinologists to adjust treatment as needed.
Importance of Glucagon in Pancreatic Insufficiency
The balance between insulin and glucagon is fundamental to glucose homeostasis, and disruption of this balance in pancreatic insufficiency requires careful clinical attention. Glucagon administration is not limited to health care professionals, and caregivers, school personnel, and family members should know where the glucagon is stored and when and how to administer it 1. Insulin-treated patients with hypoglycemia unawareness or an episode of clinically significant hypoglycemia should be advised to raise their glycemic targets to strictly avoid hypoglycemia for at least several weeks.
Key Points
- Glucagon abnormalities can contribute to glucose metabolism disturbances in pancreatic insufficiency
- Management focuses on treating the underlying pancreatic condition with PERT and glucagon emergency kits
- Regular monitoring of blood glucose and adjustment of treatment as needed is essential
- The balance between insulin and glucagon is crucial for glucose homeostasis, and disruption of this balance requires careful clinical attention 1.
From the Research
Role of Glucagon in Pancreatic Insufficiency (PI)
There is no direct evidence in the provided studies regarding the role of glucagon in pancreatic insufficiency (PI).
Pancreatic Insufficiency (PI) and Related Treatments
- The main symptoms of pancreatic exocrine insufficiency (PEI) are steatorrhoea or diarrhoea, abdominal pain, bloating, and weight loss 2.
- Pancreatic enzyme replacement therapy (PERT) remains the mainstay of PEI treatment 2, 3, 4, 5, 6.
- The recommended adult initial enzyme dose is 25 000-40 000 units of lipase per meal, titrating up to a maximum of 75 000-80 000 units of lipase per meal 2.
- Adjunct acid-suppressing therapy may be useful when patients still experience symptoms of PEI on high dose PERT 2.
- Nutritional management by an experienced dietitian is essential 2.
- PERT dosing guidelines vary widely across disease types, and many patients with exocrine pancreatic insufficiency (EPI) are underdosed 3.
- Healthcare providers should consider individualizing PERT dosing based on nutritional status and response to therapy 3.
