AbstractAbstract PDF
Diabetic peripheral neuropathy is multifactorial disorder arising from hyperglycemia and insulin deficiency. It has been suggested that oxidative stress resulting from enhanced free-radical formation and defects in antioxidant defence plays a major role among the putative pathogenic mechanisms of diabetic neuropathy. As alpha-lipoic acid, a natural antioxidant, has been suggested to improve symptoms of diabetic neuropathy, we assessed the efficacy of alpha-lipoic acid on neuropathic symptoms and peripheral nerve conduction in patients with type 2 diabetes mellitus with symptomatic polyneuropathy. METHODS: A cohort of 30 type 2 diabetic patients with symptomatic polyneuropathy received a daily dose of 600 mg alpha-lipoic acid, and was followed for 3 months. Neuropathic symptoms (pain, burning, paraesthesiae, and numbness) of the feet were scored at monthly interval and summarized as a Total Symptom Score (TSS). Nerve conduction study was done before and after 3 month treatment of alpha-lipoic acid. RESULTS: Treatment of alpha-lipoic acid given 600 mg per oral for 12 weeks improved the symptoms of diabetic polyneuropathy. Effects of alpha-lipoic acid on nerve conduction study were that in the motor nerve, the amplitudes of median nerve and tibial nerve and the conduction velocity of tibial nerve improved after 12 weeks treatment. In the sensory nerve, the conduction velocities of median nerve, ulnar nerve, and sural nerve improved after 12 weeks. CONCLUSION: alpha-Lipoic acid was effective in the treatment of diabetic peripheral polyneuropathy improving both clinical manifestations and nerve conduction. The improvement of clinical manifestations may be due to improved conduction velocity of sensory fibers.

AbstractAbstract PDF
Diabetes mellitus is a chronic illness with many metabolic complications. The prevalence of diabetes mellitus has markedly increased. Until now, however, little data have been presented for the long-term evaluation of a structured diabetes education program (SDEP) for patients with type 2 diabetes mellitus. The aim of this study was to examine the effects of the SDEP on glycemic control, lipid profiles, and self-care behavior over a four-year follow-up period. METHODS: A total of 248 diabetic patients completed the SDEP from December 1999 to September 2000. Ninety-eight patients were followed-up for more than four years and 75 of them were selected for the study, after those subjects having a baseline glycated hemoglobin(HbA1c) levels below 7.9% were excluded. The laboratory data included the glycemic control status(fasting blood sugar and HbA1c), serum creatinine, and lipid profiles. Compliance with their diet, self monitoring of blood glucose, and their exercise frequency were monitored with a questionnaire that was completed by the patients when they visited the hospital. The data were analyzed by using repeated ANOVA measures and chi2 testing for detecting trends. RESULTS: There were no significant decreases in the fasting blood glucose, creatinine, total cholesterol, triglycerides or low density lipoprotein cholesterol for the SDEP group compared with the control group. The self-care behavior of the SDEP group was much better than that of the control group and it was well maintained. Although the self-care behavior tended to deteriorate with time in the SDEP group, the exercise frequency did not change. The HbA1c level was much improved in the SDEP group(HbA1c: SDEP, 7.9+/-1.2% vs. 8.9+/-1.6% for the control; P =0.009). High density lipoprotein(HDL) cholesterol was also relatively improved in the SDEP group(HDL cholesterol: SDEP, 1.1+/-0.2 mmol/L vs. 1.0+/-0.3mmol/L for the control; P=0.006). CONCLUSIONS: The glycemic control status of diabetic patients who undertook the SDEP was satisfactory for one year after the program, although all the habitual compliance measures decreased gradually with time over the total four years. These results demonstrate that the SDEP for patients with diabetes is useful in improving their long-term glycemic control and self-care behavior. Regular and sustained reinforcement with encouragement will be required for the diabetic patients to maintain their self-care
