Question 1

What is the Meaning of Incretin?

Accepted Answer

Incretins are gastrointestinal hormones released into the bloodstream following nutrient ingestion, primarily glucose and fat. These hormones, notably Glucagon-Like Peptide-1 (GLP-1) and Glucose-dependent Insulinotropic Polypeptide (GIP), stimulate pancreatic insulin secretion in a glucose-dependent manner, minimizing hypoglycemia risk.

Question 2

What is the Context of Incretin?

Accepted Answer

These hormones function as key components of the entero-insular axis, linking the gut and pancreatic islets. Their rapid secretion after food intake initiates a coordinated metabolic response, preparing the body for nutrient absorption and storage. This anticipatory regulation is crucial for maintaining postprandial glucose homeostasis and preventing excessive blood glucose spikes.

Question 3

What is the Significance of Incretin?

Accepted Answer

Incretin hormones hold considerable importance in understanding and managing metabolic disorders, particularly type 2 diabetes mellitus. Their diminished action or resistance in individuals with type 2 diabetes contributes significantly to impaired glucose control and postprandial hyperglycemia. Recognizing their role has led to novel therapeutic strategies, offering improved glycemic management and broader health benefits.

Question 4

What is the Mechanism of Incretin?

Accepted Answer

Upon release from specialized enteroendocrine cells in the small intestine, GLP-1 and GIP circulate to target tissues. They bind to specific receptors on pancreatic beta cells, activating intracellular signaling pathways, primarily cyclic AMP, which potentiates glucose-stimulated insulin secretion. GLP-1 also suppresses glucagon secretion, slows gastric emptying, and promotes satiety, contributing to glucose regulation and weight management.

Question 5

What is the Application of Incretin?

Accepted Answer

Clinically, synthetic analogs of GLP-1 (GLP-1 receptor agonists) and inhibitors of the enzyme dipeptidyl peptidase-4 (DPP-4 inhibitors), which degrades native incretins, are widely used treatments for type 2 diabetes. These medications effectively lower blood glucose, reduce HbA1c levels, and for GLP-1 receptor agonists, often promote weight loss and offer cardiovascular benefits.

Question 6

What is the Metric of Incretin?

Accepted Answer

The effectiveness of incretin-based therapies or the status of the incretin system can be assessed through various clinical and laboratory metrics. Blood glucose levels, measured fasting or postprandially, along with glycated hemoglobin (HbA1c) values, serve as primary indicators of glycemic control. Measuring circulating levels of active GLP-1 or GIP is typically reserved for research, not routine clinical practice.

Question 7

What is the Risk of Incretin?

Accepted Answer

While generally well-tolerated, incretin-based therapies carry potential risks. Common side effects for GLP-1 receptor agonists include gastrointestinal disturbances such as nausea, vomiting, and diarrhea, particularly during treatment initiation. There is a rare risk of pancreatitis with both classes, and a boxed warning for thyroid C-cell tumors in rodents for some GLP-1 receptor agonists, though not established in humans. Patients require monitoring by healthcare professionals.
