BACKGROUND
Although the majority of diabetes mellitus (DM) patients diagnosed as adults have non-autoimmune forms of the disease, islet autoimmunity is encountered in some patients initially thought to have type 2 DM. The phenotype of DM patients with glutamic acid decarboxylase (GAD) antibodies is different from that of patients with GAD antibody-negative type 2 DM, with features such as relative leanness and hyperglycemia which may influence the development of complications. We sought to compare the prevalence of chronic complications in patients with and without the GAD antibody. METHODS: We recruited 427 patients (M: 218, F: 209) that were clinically diagnosed with type 2 DM after the age of 35 years. We measured GAD antibody and assessed the factors associated with chronic microvascular and macrovascular complications. RESULTS: Of these patients, 26 were GAD antibody-positive. The patients with GAD antibody had lower systolic blood pressure, higher high-density lipoprotein cholesterol value, and lower level of fasting and stimulated C-peptide than patients without GAD antibody (P < 0.05). Also, the patients with GAD antibody had lower prevalence of retinopathy compared with the patients without GAD antibody (19.2 vs. 47.9%; P < 0.05). The prevalence of nephropathy, peripheral neuropathy and cardiovascular autonomic neuropathy did not differ between the groups. In addition, the prevalence of coronary heart disease, cerebrovascular disease and peripheral arterial disease did not differ between the two groups. CONCLUSION: This study suggests that diabetic patients with GAD antibody have a lower risk for the development of retinopathy compared with patients without GAD antibody.

AbstractAbstract PDF
Transient hypoglycemic hemiparesis is a rare but important presentation of hypoglycemia that is frequently misdiagnosed as stroke. The development of hemiparesis as a result of hypoglycemia was first described in 1928. Thereafter over the years, several cases have been sporadically reported in Korea, but case reports of recurrent hypoglycemic hemiparesis are rare. We recently experienced a case of recurrent hypoglycemic hemiparesis in an adult with type 1 diabetes mellitus. A 30-year-old woman with type 1 diabetes receiving daily multiple subcutaneous insulin injections was admitted with right hemiparesis. She had had admitted with the same symptom and recovered with oral carbohydrates in twice 2 years ago. Her clinical course improved over 2 hours after infusion of dextrose solution. Further investigations such as CT, MRI and MRA revealed no abnormality

BACKGROUND
Increased platelet aggregability is known to be one of the important risk factors for diabetic vascular complications. The relationship between platelet aggregability and diabetic macrovascular complications, varying severity of diabetic microvascular complications and other possible factors was evaluated in Korean adults. METHODS: Platelet aggregability was measured with platelet rich plasma by addition of adenosine diphosphate (ADP) in 45 cases. Normal control group (n=15) was compared with diabetics without macrovascular complications (n=15), diabetics with macrovascular complications (n=15) and several groups divided accoring to the severity of microvascular complications. RESULTS: 1) The mean maximum value of platelet aggregation was 70.3+/-5.3% in control group, and 80.0+/-7.3% in diabetics (p<0.005). 2) The mean maximum value of platelet aggregation was 78.0+/-5.5% in diabetics without macrovascular complications and 83.5+/-7.1% in diabetics with macrovascular complications (p=0.093). 3) The mean maximum value of platelet aggregation was 77.0+/-5.1% in normoproteinuria group, 78.1+/-7.3% in microproteinuria group, and 82.9+/-6.2% in overt proteinuria group (p=0.083). 4) The mean maximum value of platelet aggregation was 77.2+/-6.8% in diabetes without neuropathy group and 82.9+/-6.2% in diabetes with neuropathy group (p=0.114). 5) The mean maximum value of platelet aggregation was 79.3+/-4.9% in diabetes with normal funduscopic findings, 80.2+/-7.3% in diabetes with background retinopathy and 81.6+/-7.9% in diabetes with proliferative retinopathy (p=0.852). 6) Blood glucose showed positive correlations with the mean maximum platelet aggregation ( =0.529, p<0.005). CONCLUSION: The elevated mean maximum value of platelet aggregation was found in diabetics and there were no significant differences between macrovascular complications and between varying severity of retinopathy, neuropathy and proteinuria. Blood glucose showed positive correlations with mean maximum platelet aggregation. Hyperglycemia was a major risk factor affecting platelet aggregation in diabetics and its control may play an important role in prevention of diabetic vascular complications.

BACKGROUND
The risk of atherosclerosis is increased in subjects with diabetes mellitus. Lipoprotein(a) [Lp(a)] is an independent risk factor for atherosclerotic vascular disease in subjects without diabetes. The contribution of Lp(a) to the increased risk for atherosclerosis and diabetic complications in subjects with diabetes is not well known. In this report we examined the relationship between Lp(a) levels and development of vascular (macro- and microvascular) complications, and the relationship between Lp(a) and other risk factors for vascular complications in subjects with non-insulin-dependent diabetes mellitus(NIDDM), METHODS: For this study we evaluated 152 patients with NIDDM(72 women and 80 men). Lp(a) level was measured with N-Latex Lp(a) Reagent. Electrocardiography, coronary angiography, brain CT/MRI, doppler velocimetry and peripheral angiography were done for diagnosis of macravascular complieations, and fundus camera, nerve conduction velocity, BBV (beat to beat variation), VPT(vibration perception threshold) and 24-hour urine protein amount were examined for diagnosis of microvascular complications. RESULTS: Lp(a) levels in subjects with ischemic heart disease, cerebrovascular disease and diabetic retinopathy were significantly higher than those in subjects without above mentioned diseases. ApoB/ApoA1 ratio and LDL-cholesterol levels in subjects with Lp(a) level>30mg/dL were significantly higher than those in subjects with Lp(a) level 30mg/dL, and Lp(a) has a positive correlation with ApoB/ApoA1 ratio and LDL-cholesterol in NIDDM patients with vasculopathy. CONCLUSION: These results suggest that high Lp(a) levels seem to be associated with macrovascular and microvascular(especially with retinopathy) complications in subjects with NIDDM and Lp(a) level should be measured in the NIDDM with high level of ApoB/ApoA1 ratio and/or LDL-eholesterol.
