C-peptide is a byproduct of insulin production, mirroring the amount of insulin secreted by the pancreas.作者：PJ Guillausseau·1983·被引用次数：7—C-Peptide in Factitious Hypoglycemia from Sulfonylurea| Diabetes Care | American Diabetes Association. Therefore, c-peptide levels serve as a valuable indicator of endogenous insulin production.Chronic Sulfonylurea Treatment and Hyperglycemia ... Sulfonylureas, a class of oral medications widely used to treat type 2 diabetes, work by stimulating the pancreas to release more insulin.作者：SK Venugopal·2023·被引用次数：25—A C-peptide level is very useful in the differential diagnosis since it isonly elevated with a beta cell tumor, insulinoma, and sulfonylurea... This direct action on insulin secretion has significant implications for both therapeutic benefits and potential adverse effects, such as hypoglycemia.

Research has consistently demonstrated that sulfonylureas stimulate the secretion of both insulin and c-peptide. This means that when a patient is taking sulfonylureas, their c-peptide levels are expected to rise. Studies have explored the quantitative insulin and C-peptide concentrations in diabetic patients taking sulfonylurea agents. For instance, one study noted that insulin ≥ 3.9 μIU/mL and c-peptide ≥ 1Effect of Sulfonylurea on Glucose, Insulin and C‐peptide ....4 ng/mL, coupled with a low glucose level (less than 49 mg/dL), are indicative of sulfonylurea-induced hypoglycemia.2025年11月11日—HighC-peptidelevel and high insulin level indicated endogenous hyperinsulinemia, e.g., insulinoma orsulfonylureaintoxication.

The effect of sulfonylurea on glucose, insulin and C-peptide levels has been a subject of ongoing investigation.Sulfonylurea challenge test in subjects diagnosed with ... Early research in the 1980s indicated that sulfonylureas could diminish the blood glucose increment after a meal, suggesting beneficial effects in managing hyperglycemia, even in patients with liver disease and markedly elevated basal levels of plasma IRI and c-peptide concentrationsHypoglycemia Secondary to Sulfonylurea Ingestion in a .... More recent studies continue to explore these effects. For example, the duration of sulfonylurea treatment has been associated with a decline in c-peptide concentration over time, suggesting potential long-term effects on beta-cell function.

In the context of hypoglycemia, distinguishing between endogenous insulin production and exogenous sources is crucial for accurate diagnosis and treatment.2025年11月11日—HighC-peptidelevel and high insulin level indicated endogenous hyperinsulinemia, e.g., insulinoma orsulfonylureaintoxication. LowC-peptide... Elevated c-peptide levels, along with elevated insulin levels, can point towards endogenous hyperinsulinemia, which may be caused by conditions like insulinoma or, importantly, sulfonylurea intoxication. The C-peptide test is very useful in this differential diagnosis, as it is typically elevated in situations involving sulfonylurea ingestion, alongside beta-cell tumors or insulinoma. In contrast, the elevation in the c-peptide level can rule out exogenous insulin as the cause of hypoglycemia. While the molar ratio of insulin to c-peptide is generally around 1:1, sulfonylurea ingestion also tends to preserve this ratio, often staying at 1 or less.

The potential for sulfonylureas to induce hypoglycemia necessitates careful monitoring and understanding of their impact. Sulfonylureas thus seem to have beneficial effects when managed appropriately, but their propensity to stimulate insulin release can lead to sulfonylurea-induced hypoglycemiaBiochemistry, C Peptide - StatPearls - NCBI Bookshelf - NIH. When evaluating hypoglycemia, assessing insulin and C-peptide levels observed in sulfonylurea-induced hypoglycemia is a standard approach作者：CR DeWitt·2007·被引用次数：16—Objectives: We will describeinsulin and C-peptide levels observed in sulfonylurea-induced hypoglycemiaand determine whether these levels differed if ....

A sulfonylurea challenge can elicit a greater increase in c-peptide levels, even as glucose levels decrease, further underscoring the drug's potent effect on insulin secretion.

Furthermore, understanding the role of c-peptide in various diabetic scenarios is important. A normal or high c-peptide level in a patient with diabetes, especially when on sulfonylureas, often indicates residual beta-cell function. In some cases, the combination of metformin and sulfonylurea therapy has been associated with a low c-peptide level, a finding that warrants further investigation into the patient's individual response.
