It usually occurs in patients with poorly controlled or insulin-resistant diabetes mellitus. We present a 57-year-old woman with scleredema diabeticorum with hemoglobin A1c 6.1% (normal, 4.7% - 6.2%) and impaired glucose tolerance. Alcian blue staining at pH 7.0 illustrated deposits of acid mucopolysaccharides between the collagen bundles in the reticular dermis, but the staining at pH 1.5 did not show the deposits. This case indicates that scleredema diabeticorum may be an early indicator of undiagnosed diabetes mellitus in some cases, and that impaired glucose tolerance test should be performed for individuals with scleredema even though the hemoglobin A1c level is within the normal range.展开更多

Beta cell dysfunction and insulin resistance are the main defects in type 2 diabetes mellitus(type 2 DM) and even normoglycemic IGT patients manifest these defects. Beta cell dysfunction and insulin resistance also contribute to the progression of IGT to type 2 DM. Improving insulin sensitivity and/or preserving functions of beta-cells can be a rational way to normalize the GT and to control transition of IGT to type 2 DM. Loosing weight, for example, improves whole body insulin sensitivity and preserves beta-cell function and its inhibitory effect on progression of IGT to type 2 DM had been proven. But interventions aiming weight loss usually not applicable in real life. Pharmacotherapy is another option to gain better insulin sensitivity and to maintain beta-cell function. In this review, two potential treatment options(lifestyle modification and pharmacologic agents) that limits the IGT-type 2 DM conversion in prediabetic subjects are discussed.展开更多

Blood glucose of 2 h after oral administration of 75 g glucose (2 h BG) was measured. WHO criteria were used for the diagnosis of NIDDMand IGT. Meanwhile epidemiological data were collected. Blood pressure, height, weight, waist and hip girths were measured. The crude prevalence was found to be 5. 82% (men 4.62%,woman 6. 69%) for NIDDM, 5. 87% (men 5. 30%, women 6. 29% ) for IGT and 14. 72% (men 16. 50%, women 13. 43 % ) for hypertension in the population obove 20 years of age. Age-adjusted prevalence was 4. 63% for NIDDM, 5. 07 % for IGT and 11. 19% for hypertension. Age increase (>40 years), obesity (BMI≥27) and central fat distribution (WHR≥0.88) were the risk factors for both diabetes and hypertension. The subjects≥40 years of age and obesity were the high risk population of NIDDM, IGT and hypertension. They were the target population for theprevention and treatment of diabetes and hypertension in the community level. High prevalences of NIDDM,IGT and hypertension were observed in the community population in Jiangsu province. To reinforce the prevention and treatment of these disorders in the province is imperative.展开更多
