Prevalence of Chronic Complications in Korean Patients with Type 2 Diabetes Mellitus Based on the Korean National Diabetes Program

BACKGROUND: The Korean National Diabetes Program (KNDP) cohort study is performing an ongoing large-scale prospective multicenter investigation to discover the pathogenesis of type 2 diabetes in Korean patients. This study was performed to examine the prevalence of chronic complications in patients with type 2 diabetes among those registered in the KNDP cohort within the past 4 years. METHODS: This study was performed between June 2006 and September 2009 at 13 university hospitals and included 4,265 KNDP cohort participants. Among the participants, the crude prevalence of microvascular and macrovascular diseases of those checked for diabetes-related complications was determined, and the adjusted standard prevalence and standardization of the general population prevalence ratio (SPR) was estimated based on the 2005 Korean National Health and Nutrition Examination Survey (KNHANES) population demographics. RESULTS: Among the KNDP registrants, 43.2% had hypertension, 34.8% had dyslipidemia, 10.8% had macrovascular disease, and 16.7% had microvascular disease. The SPR of the KNDP registrants was significantly higher than that of the KNHANES subjects after adjusting for demographics in the KNHANES 2005 population. However, with the exception of cardiovascular disease in females, the standardized prevalence for the most complicated items in the survey was significantly higher than that in the KNHANES subjects. CONCLUSION: The prevalence of macrovascular disease and peripheral vascular disease were significantly higher in Korean patients with type 2 diabetes than in the normal population. However, no significant difference was noted in the prevalence of cardiovascular disease in females.

Differences in Insulin Sensitivity and Secretory Capacity Based on OGTT in Subjects with Impaired Glucose Regulation

BACKGROUND: This study examined whether defects in insulin secretion contribute to the development and progression of type 2 diabetes mellitus (T2DM). METHDOS: Plasma insulin and glucose were measured after a glucose tolerance test to calculate the insulinogenic index (IGI) and the HOMA-IR Homeostasis model assessment of insulin resistance in subjects with normal glucose tolerance (NGT), prediabetes (preDM, n=49), and T2DM patients with disease duration 5 years (n=37). Plasma proinsulin and adiponectin levels were also measured as a parameter of insulin secretion and resistance. RESULTS: The mean HOMA-IR increased and the adiponectin levels decreased relative to the deterioration of glucose tolerance in NGT and preDM subjects. However, differences in the HOMA-IR were not related to disease duration in T2DM subjects. The mean IGI was similar in NGT and preDM subjects, but there were significant deteriorations in IGI relative to the duration of diabetes. CONCLUSIONS: Defects in both insulin sensitivity and insulin secretion contribute to T2DM, but decreased insulin secretion may be more important in the development and progression of T2DM.

A Case of 45,X Turner's Syndrome with Iron Deficiency Anemia due to Menometrorrhagia and Spontaneous Sexual Development / 대한내분비학회지

Short stature and gonadal dysgenesis are two characteristic clinical features of Turners syndrome. Very rarely, patients with Turners syndrome may menstruate and even be fertile. We experienced a case of Turners syndrome with spontaneous sexual development and menstruation. A 16-year-old girl was referred for severe anemia and menometrorrahgia. She had nearly normal features, with the exception of a short stature and a single right kidney. Also, she had spontaneous development of secondary sexual characteristics. We performed and anemia study and evaluated her short stature. In chromosomal study of her bone marrow and peripheral blood lymphocytes, she was revealed to have monosomy 45,X. Herein, this case is reported, with a brief review of literature
