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.

BACKGROUND/AIMS: Albuminuria is an early indicator of renal damage in type 2 diabetes mellitus, and has been recognized as a risk factor for peripheral arterial disease (PAD). The aim of this study was to assess the association between albuminuria and PAD in Korean type 2 diabetes patients. METHODS: Our retrospective study included 390 consecutive patients with type 2 diabetes mellitus. The ankle-brachial index (ABI) and toe-brachial index (TBI) were used to assess PAD. The urinary albumin-creatinine excretion ratio (UAE) was evaluated by determining the albumin/creatinine ratio (ACR) in the first voided morning urine sample. RESULTS: Duration of diabetes, serum creatinine levels, and UAE were significantly higher in patients with low ABI scores (< 0.9) than in those with normal ABI scores (> or = 0.9). Age, duration of diabetes, and UAE were significantly higher in patients with low TBI scores (< 0.6) than in those with normal TBI scores (> or = 0.6). Albuminuria was independently associated with low ABI (OR = 1.980, 95% CI = 1.001-3.918). It was also independently associated with low TBI and normal ABI (OR = 3.149, 95% CI = 1.260-7.871). CONCLUSIONS: The results of this study suggest that albuminuria may be associated with PAD, including in arteries distal to the ankle joint.

Hypoglycemia in diabetic patients is usually caused by excessive exogenous insulin or the administration of an insulin secretagogue relative to the prevailing glucose concentration. Thus, the clinical manifestations of hypoglycemia are usually not observed in diabetic patients after either insulin or an oral hypoglycemic agent is discontinued. In contrast, diabetic ketoacidosis results from relative or absolute insulin deficiency. Although about 40% of diabetic patients who inject human insulin have insulin antibodies, these antibodies seldom significantly affect the glycemic control. It has not been reported in the literature that insulin antibody in the setting of human insulin therapy is associated with diabetic ketoacidosis and subsequent hypoglycemia. We describe here a rare case of spontaneous hypoglycemia due to insulin antibody after the improvement of diabetic ketoacidosis in a patient with type 2 diabetes mellitus and who had been treated with human insulin.

BACKGROUND: The initial insulin dose is often determined by clinical experience or with a formula using the body weight. However, it may be difficult to determine the initial insulin dose because various factors such as insulin sensitivity and the glycemic status can influence the insulin requirement. The purpose of this study was to assess the factors that influence the initial insulin requirement in insulin naive patients with type 2 diabetes mellitus. METHODS: A total 128 patients who were admitted for glycemic control were investigated. The patients were managed with long-acting insulin glargine and rapid-acting insulin lispro. RESULTS: The basal insulin requirement was positively correlated with waist circumference, body mass index (BMI), the HbA1C, AST, ALT, fasting plasma glucose and 2-hour postprandial glucose levels and the homeostasis model assessment of insulin resistance (HOMA-IR), but it was negatively correlated with age and the stimulated C-peptide level. The daily insulin requirement was positively correlated with waist circumference, BMI, the HbA1C, AST, ALT, triglyceride, fasting plasma glucose and 2-hour postprandial glucose level and HOMA-IR, but it was negatively correlated with age. On the multiple linear regression analysis, the basal insulin requirement was independently associated with BMI (beta = 0.507, p < 0.001), the 2-hour postprandial glucose level (beta = 0.307, p < 0.001), the ALT level (beta = 0.214, P = 0.015) and the meal-stimulated C-peptide level (beta = -0.209, P = 0.010). The daily insulin requirement was independently associated with BMI (beta = 0.508, p < 0.001) and the 2-hour postprandial glucose level (beta = 0.404, p < 0.001). CONCLUSION: Our results show that the BMI and 2-hour postprandial glucose level are useful predictors of the initial insulin requirement in insulin naive type 2 diabetic patients. It may be prudent to consider the other various factors that influence the insulin requirement together when insulin therapy is required.

BACKGROUND/AIMS: We investigated the associations among body mass index (BMI), insulin resistance, and beta-cell function in Korean patients newly presenting with type 2 diabetes. METHODS: In total, 132 patients with new-onset type 2 diabetes mellitus were investigated. A standard 75-g oral glucose tolerance test was performed, and the indices of insulin secretion and insulin resistance were calculated. RESULTS: A higher BMI was associated with higher homeostasis model assessment values for insulin resistance (HOMA-IR), homeostasis model assessment of beta-cell function (HOMA-beta), and insulinogenic index as well as lower levels of insulin sensitivity index composite (ISIcomp) and disposition index (DI). In multiple regression models, BMI had independent positive associations with HOMA-IR, ISIcomp, and HOMA-beta and inverse associations with the DI. CONCLUSIONS: Our results showed that BMI had independent positive associations with indices of insulin resistance and an inverse association with beta-cell function adjusted for insulin resistance in Korean patients newly presenting with type 2 diabetes.

BACKGROUND/AIMS: Many studies have demonstrated an association between hemoglobin levels and cardiovascular disease in diabetic patients. The aim of this study was to determine whether there is an association between hemoglobin concentrations and various clinical parameters, including metabolic factors, plasma C-peptide response after a meal tolerance test, and microvascular complications, in Korean patients with type 2 diabetes. METHODS: In total, 337 male patients with type 2 diabetes were recruited. All subjects were subjected to a meal tolerance test and underwent assessment of hemoglobin levels, fasting and postprandial beta-cell responsiveness, and microvascular complications. RESULTS: Patients with lower hemoglobin concentrations had a longer duration of diabetes, a lower body mass index, and lower concentrations of total cholesterol, triglycerides, and low-density lipoprotein cholesterol. They also had lower levels of postprandial C-peptide, Delta C-peptide, and postprandial beta-cell responsiveness. They had a higher prevalence of retinopathy and nephropathy. In multivariate analyses, there was a significant association between nephropathy and hemoglobin concentration. Also, hemoglobin concentrations were independently associated with Delta C-peptide levels and postprandial beta-cell responsiveness. CONCLUSIONS: Hemoglobin concentrations are associated with postprandial C-peptide responses and diabetic nephropathy in patients with type 2 diabetes.
