Bone Mineral Density in Prediabetic Men / 당뇨병

BACKGROUND: There are many studies regarding the effects of insulin on bone metabolism and changes in bone mineral density (BMD) in the setting of diabetes. The effect of prediabetes on BMD is not known. METHODS: A total of 802 men participated in the Korea Rural Genomic Cohort Study (in Geumsan County). According to the results of an oral glucose tolerance test, subjects were classified into normal, prediabetic, and diabetic categories. One hundred twenty-four subjects diagnosed with type 2 diabetes were excluded, leaving 678 subjects for the study inclusion. BMD was estimated with a quantitative ultrasonometer. RESULTS: The average BMD T scores of normal and prediabetic subjects were -1.34 +/- 1.42 and -1.33 +/- 1.30, respectively; there was no significant difference in the BMD T scores between these groups. The BMD T score was inversely associated with age and positively correlated with body weight, body mass index, total cholesterol, low density lipoprotein cholesterol, and HbA1c. On multiple linear regression analysis, low density lipoprotein cholesterol was the only statistically significant variable for prediabetes (beta = 0.007, P = 0.005). On the stepwise regression analysis, age (beta = -0.026, P < 0.001), the body mass index (beta = 0.079, P < 0.001), and low density lipoprotein cholesterol (beta = 0.004, P = 0.016) were significant variables for prediabetes. CONCLUSIONS: There was no significant difference in the BMD T score between the normal and prediabetic subjects. Further studies are needed regarding the association of fracture risk and changes in BMD with the development of overt diabetes.

Clinical features of 28 acutely toxic hepatitis patients who ingested Dictamnus dasycarpus: A single center clinical experience / 대한내과학회지

BACKGROUND/AIMS: The aim of this study was to investigate the clinical features of acutely toxic hepatitis associated with ingesting Dictamnus dasycarpus (D. dasycarpus). METHODS: Between January 2004 and July 2009, 28 patients were enrolled in this study. We reviewed the medical records retrospectively. Acutely toxic hepatitis associated with D. dasycarpus was diagnosed by a Roussel Uclaf Causality Assessment Method Values (RUCAM) score of 6 or above. All patients were tested for viral hepatitis A, B, C, cytomegalovirus, and Epstein-Barr virus. Other tests included anti-nuclear antibody, anti-mitochondrial antibody, and anti-smooth muscle antibody. Abdominal pelvic computed tomography was performed. RESULTS: The incidence was female predominant (64% vs. 36%). The mean patient age was 53.0+/-11 years. The symptoms were jaundice (68%), fatigue (57%), nausea (43%), anorexia (43%), and abdominal pain (24%). The mean RUCAM score was 7.0+/-0.8. The biochemical patterns of hepatotoxicity were hepatocellular (n=23, 82%) and mixed types (n=5, 18%). Radiologic findings were as follows: normal findings (29%), lymphadenopathy (50%), edema of the gall bladder wall (46%), periportal edema (43%), splenomegaly (11%), fatty liver (11%), and ascites (7%). The mean hospitalization period was 21.6+/-11.6 days. The mean duration of recovery from hepatitis was 56.6+/-30.4 days, and all patients recovered completely from the toxic hepatitis. One patient who had severe jaundice developed a complication of pure red cell aplasia during the hospitalization period. CONCLUSIONS: The biochemical pattern of liver injury was hepatocellular predominant. Although the initial manifestations and clinical course were variable, all patients completely recovered with supportive care or steroid treatment. Toxic hepatitis was accompanied by pure red cell aplasia in one patient.
