Aneurysmal subarachnoid hemorrhage (SAH) causes temporary glucose metabolism issues, primarily due to pancreatic beta-cell dysfunction and insulin resistance in the first week. These disturbances in glucose regulation resolve over time in SAH patients.
Area of Science:
- Neurocritical care
- Endocrinology
- Metabolic disorders
Background:
- Hyperglycemia is common and a risk factor for poor outcomes in aneurysmal subarachnoid hemorrhage (SAH).
- Underlying mechanisms of hyperglycemia in SAH patients are not well understood, despite being often attributed to insulin resistance.
Purpose of the Study:
- To prospectively investigate temporal changes in glucose metabolism after aneurysmal SAH.
- To explore correlations between glucose metabolism disturbances and stress markers in SAH patients without prior metabolic abnormalities.
Main Methods:
- Oral glucose tolerance tests (OGTTs) and assessments of insulin resistance, pancreatic beta-cell function, free fatty acids (FFA), and cortisol were conducted.
- SAH patients without insulin therapy were compared with reference values during hospitalization and follow-up.
Main Results:
- All patients showed glucose intolerance at days 3 and 7 post-SAH.
- Elevated fasting glucose and FFA, with normal insulin levels, were observed in the first two weeks.
- Impaired pancreatic beta-cell function and insulin resistance were noted, correlating with cortisol and FFA levels.
Conclusions:
- Aneurysmal SAH patients experience transient glucose metabolism abnormalities.
- These disturbances in the first week are mainly due to temporary pancreatic beta-cell dysfunction and insulin resistance.
