Background: Angiogenesis in diabetic patients is often caused by hyperglycemia induced by hypoxia Objective: The aim of this study was to analyze the serum level of Hypoxia Inducible Factor -1α (HIF-1α) and Vascular Endothelial Growth Factor (VEGF) between March until Desember 2020. Methods: This is a cross-sectional analytic methods, 135 patients with Type 2 Diabetes 48 samples with Microvascular complication and 87 samples with non-microvascular complication were recruited from the various primary health care centers in Medan city and surrounding areas in North Sumatera. VEGF levels and HIF-1α tested were done with ELISA methods in the laboratory of Medical Faculty, Universitas Sumatera Utara. Statistical analysis was performed using the IBM SPSS Statistics version 24. The significance level was set up to 0.005. Results: The median HIF-1 levels in patients with microvascular complications were lower than those without microvascular complications, with a range of HIF-1α values in non-complicated samples (0.02-13.96) ng/ml and a range of HIF-1α values in vascular complications (0.52- 8.87) mg/dL. There was a significant difference in HIF-1α levels in patients with Type-2 DM with complications compared to those without complications (p 0.005). Conclusion: HIF-1α and VEGF levels showed the development in vascularity. With the higher level of HIF-1α, an increase in VEGF levels were found, indicating the angiogenesis is occurring. Although complications have not yet occurred, it is predicted that high VEGF values will cause vascular complications in the future.

Key words: type 2 diabetes mellitus, blood sugar level, Hba1c, lipid profile, VEGF, HIF-1α .
