Diabetes mellitus and co-morbid depression: treatment with milnacipran results in significant improvement of both diseases (results from the Austrian MDDM study group)

Abstract

Co-morbid depression is common in patients with diabetes mellitus and has a negative impact on diabetes self-care, adherence to treatment and the development of complications. Effective treatment of depression has been associated with improvement in metabolic parameters. We evaluated the feasibility of a two question screen for co-morbid depression in diabetic patients and studied the effect of the serotonin norepinephrine reuptake inhibitor antidepressant, milnacipran, on metabolic and psychological parameters in 64 type 2 diabetic patients with co-morbid depression. The severity of depression was evaluated using the Beck Depression Inventory (BDI). Patients received milnacipran, and diabetes was treated according to the guidelines of the Austrian Diabetes Association in a 6-month open label study. Metabolic parameters and BDI were measured at baseline and after 1, 3 and 6 months. 46 patients satisfied the criteria for an antidepressant response (reduction of baseline BDI score of at least 50%). Hemoglobin A1c, fasting blood glucose, body mass index, total and LDL-cholesterol and serum triglyceride levels were all significantly decreased in these patients at the end of the study whereas in antidepressant non-responders these parameters were not significantly changed. Diagnosis and treatment of depression is an important factor for the improvement of metabolic control in patients with type 2 diabetes and co-morbid depression.
