Aims: This study aimed to assess whether transcutaneous oxygen tension (TcPO2) was associated with the presence of microvascular complications in type 2 diabetic (T2D) patients and whether TcPO2 could act as an independent risk factor for predicting the occurrence of microvascular events in these patients.
Methods: We recruited 436 patients with T2D. Based on the presence of diabetic kidney disease, diabetic retinopathy, and/or diabetic peripheral neuropathy, the patients were divided into groups with and without microvascular complications. The differences between these 2 groups were examined using the chi-square test and the t test. The influencing factors of diabetic microangiopathy were studied using a logistic regression analysis.
Results: The results showed that sex, diabetes duration, smoking history, TcPO2, and HbA1c were independent risk factors for the occurrence of diabetic microvascular events (P<0.05). In particular, the risk of developing microvascular complications was 10.16 times higher in patients with low TcPO2 than that in those with high TcPO2 (OR=10.157, 95% CI: 4.602-22.418).
Conclusion: This study showed that TcPO2 was significantly negatively associated with the occurrence of microvascular events in type 2 diabetic patients and that TcPO2 may be an independent risk factor for predicting the occurrence of microvascular complications in these patients. These results suggest that for type 2 diabetes mellitus with clinically reduced TcPO2, we should pay close attention to the occurrence of microvascular complications and engage in early prevention.
