Background: Hyperglycemia is frequent in sepsis, even in patients without diabetes or impaired glucose metabolism. It is a consequence of inflammatory response and stress, so its occurrence is related to severity of illness. However, not all severely ill develop hyperglycemia and some do even in mild disease. We hypothesized the existence of latent disturbance of glucose metabolism that contributes to development of hyperglycemia and that those patients might have increased risk for diabetes.
Methods: Patients admitted with sepsis and no history of impaired glucose metabolism were included and divided in the hyperglycemia group (glucose >or=7.8 mmol/L) and normoglycemia group. Severity of sepsis was assessed. Surviving patients without diabetes at discharge were followed-up for 5 years to investigate risk for development of diabetes.
Results: Hyperglycemia was related to severity of sepsis. Follow-up was finished for 55 patients with hyperglycemia, of which 8 (15.7%) developed diabetes, and 118 patients with normoglycemia, of which 5 (4.2%) developed diabetes (P = .002). Relative risk for developing type 2 diabetes was 4.29 (95% CI, 1.35-13.64).
Conclusion: Patients with hyperglycemia in sepsis who are not diagnosed with diabetes before or during the hospitalization should be considered a population at increased risk for developing diabetes.
