Effect of Intensive Therapy of Multiple Factors Intervention on Vascular Complications in Type 2 Diabetes

The effects of intensive versus regular therapy on incidence and progress of microalbuminuria in type 2 diabetes were compared. During a follow-up of 3 years, 96 cases of diabetes mellitus were randomized to intensive and regular therapy groups. HbA 1c goal was same in the two groups, but the goal of blood pressure (Bp) and lipid was more strict in the intensive therapy group than in the regular therapy group. There was statistically significant difference in the incidence and progression of vascular complications between the two groups. Logistic stepwise-regression analysis (odds ration, OR) showed that there was significant difference in the progression of nephropathy (OR 0.24, 95 % CI 0.12-0.76), retinopathy (OR 0.38, 95 % CI 0.16-0.88), peripheral neuropathy (OR 0.42, 95 % CI 0.22-0.86) and autonomic neuropathy (OR 0.29, 95 % CI 0.12-0.86) between the two groups (P<0.01). It was concluded that intensive blood glucose controlling could retard diabetic vascular complications. Intensive therapy of multiple factors interventions (controlling Bp, regulating blood lipid, improving microcirculation) could decrease various risk factors for diabetic vascular complications.
