A Case of Diabetic Ketoacidosis Induced by Sodium-Glucose Cotransporter 2 Inhibitor / 임상당뇨병

Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a new class of oral antihyperglycemic drugs; inhibition of the cotransporter allows for increased renal glucose excretion that consequently leads to reduced plasma glucose level. We report a rare case of a 73-year-old woman with type 2 diabetes mellitus who developed severe ketoacidosis caused by an SGLT2 inhibitor. At admission, severe ketoacidosis with arterial PH 6.99 was observed, though her serum glucose level of 232 mg/dL was not excessively high. It is necessary to pay attention to patients with type 2 diabetes being treated with an SGLT2 inhibitor, as anorexia, diarrhea, dehydration, and weight loss can develop in conjunction with a high fat/protein diet.

Association between Change in Body Weight and Insulin Resistance in Individuals at Increased Risk of Diabetes / 대한내과학회지

BACKGROUND/AIMS: The present study aimed to investigate the associations between a change in body weight from 20 years of age to the present with insulin resistance and several parameters of metabolic syndrome in individuals at an increased risk of diabetes. METHODS: From patients with a diagnosis related to an increased risk of diabetes who were examined at our endocrinology clinic from January 2012 to December 2014, the present study recruited 125 individuals between 30 and 64 years of age with hemoglobin A1c levels from 5.7 to 6.4%. The change in body weight of each patient from 20 years of age to the present was retrospectively determined, and the associations of this change with insulin resistance and several parameters of metabolic syndrome were analyzed. RESULTS: The average gain in body weight after 20 years of age was 11.3 kg and there was no significance difference between the male and female patients. The proportion of overweight and obese patients at 20 years of age was 14%, but was 74% at the time of the visits to our endocrinology clinic. A change in body weight was significantly correlated with body mass index, insulin resistance, and waist circumference. Additionally, as the tertile of change in body weight increased, fasting insulin levels, insulin resistance, and the prevalence of abdominal obesity significantly increased. CONCLUSIONS: In the present study, an increase in body weight from 20 years of age to the present was correlated with insulin resistance and several parameters of metabolic syndrome in individuals at an increased risk of diabetes.

Association between Diabetes Education Status and Clinical Outcomes of Patients with Diabetes Mellitus: Analysis of the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V) / 임상당뇨병

BACKGROUND: We aimed to study the importance of diabetes education by investigating diabetes education rate and the associations between the presence/absence of diabetes education and the clinical outcomes of diabetic patients in Korea. METHODS: In the Fifth Korea National Health and Nutrition Examination survey (KNHANES V), a cross-sectional national survey during 2010 and 2012, 1498 subjects aged over 30 years and older were diagnosed with diabetes by doctors. The subjects were analyzed by a complex samples model. RESULTS: Only 20.3% of diabetes patients received diabetes education, and this was not significantly different between age groups. Education was delivered in hospitals/clinics, public health centers, and public lectures (15.7%, 3.0% and 1.4%, respectively). After adjusting for age, sex, and duration of diabetes, the factors independently associated with the presence of diabetes education were higher education level, frequent walking habit, and parameters regarding the presence of dyslipidemia, insulin treatment, and non-pharmacologic treatment. Among continuous variables, only the duration of diabetes was associated with diabetes education status; metabolic parameters were not associated with diabetes education status. CONCLUSION: Diabetes is a chronic disease and education on diabetes is very important. The education rate was low and quality of the education is doubtful. An effort to raise the rate of diabetes education and further study to raise the quality of diabetes training are necessary.

Management of Hyperglycemia in Type 2 Diabetes: A Patient-Centered Approach Developed by the American Diabetes Association and the European Association for the Study of Diabetes / 임상당뇨병

In 2012, the American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD) published new guidelines for the management of type 2 diabetes, emphasizing the need to individualize treatment goals with preference, need and cost-effects compared with the 2008 ADA/EASD algorithm. These ADA/EASD recommendations provided characteristics of medications in view of improved pharmacodynamics, effects, side effect and cost. The ADA/EASD explained stratification of treatment based on HbA1c and no preferred sequential order for regimens involving dual and triple therapy, indicating the strong effects of insulin therapy in the case of triple therapy. In this section, we summarize "Management of Hyperglycemia in Type 2 Diabetes: A Patient-Centered Approach by the American Diabetes Association (ADA) and the European Association for the Study of Diabetes" in Korean.

Detection of A-V shunting with CO2-DSA in hepatocellular carcinoma

The presence of A-V shunting in hepatocellular carcinoma is an important factor for deciding the prognosis and in the management with transarterial chemoembolization. Twenty-four patients with hepatocellular carcinoma performed with CO2-DSA and iodinated-DSA were reviewed for the evaluation of visibility of A-V shunting. It was classified by the visibility into clearly visible, faintly visible and invisible. Also the authors evaluated neovascularity and tumor staining. And we checked side effects after the injection of CO2 gas during CO2-DSA. A-V shunting was noted in 19 cases(63%), which were clearly visible in 15 of 19 cases(79%) on CO2-DSA and in 7 of 19 cases(37%) on iodinated-DSA. In 3 cases, A-V shunting was noted only on CO2-DSA. CO2-DSA(17%)was inferior to iodinated-DSA in detection of neovasculaity and tumor staining. Side effects from CO2-DSA were abdominal pain(1 case) and chest discomfort(1 case) but improved within several minutes. In conclusion, CO2-DSA is a sensitive and effective method for the detection of A-V shunting in hepatoma.
