Clinical Trial
Improved assessment of aortic calcification in Japanese patients undergoing maintenance hemodialysis.
Vascular calcification is a feature of arteriosclerosis and in hemodialysis (HD) patients it may be severe, even at a relatively young age, and is closely related to the overall prognosis. We used the aortic calcification area index (ACAI), derived from the aortic calcification index (ACI), to evaluate and analyze the risk factors for abdominal aortic calcification in HD patients. ⋯ Risk factors for abdominal aortic calcification in HD patients include age, systolic blood pressure, and serum calcium, according to ACAI evaluation. The ACAI was accurate and useful for evaluating abdominal calcification.

Changes in metabolic syndrome and its components with lifestyle modification were evaluated in Japanese men. ⋯ Lifestyle modification is useful for improving metabolic syndrome and its components. However, items of metabolic syndrome were improved, even when the abdominal circumference was greater than the normal value for Japanese men.

The aim of this cross-sectional study was to investigate the association between airflow obstruction and the metabolic syndrome (MS) or its components in Japanese men. ⋯ Airflow obstruction of GOLD stage II-IV might be associated with MS, waist circumference and blood pressure components in Japanese men.

Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive sterol storage disease caused by a mutated sterol 27-hydroxylase (CYP27A1) gene. We analyzed the CYP27A1 gene in two Japanese CTX patients. The CYP27A1 gene was amplified by PCR and screened by PCR-SSCP. ⋯ Case 1 was a compound heterozygote for Arg104Gln in exon 2 and Arg441Gln in exon 8. To our knowledge, this is the first report in which the Arg104Gln mutation is identified in CTX patients. Probably case 2 would be a compound heterozygote for Arg441Trp in exon 8 and a mutation that was not identified.

Patients with liver disease usually have an imbalanced nutrient and energy metabolism that leads to malnutrition and seriously affects their prognosis. Therefore, it is of great clinical interest to understand the resting energy expenditure (REE) and oxidation rates of glucose, fat, and protein in these patients. ⋯ These data demonstrated that Chinese patients with chronic hepatitis B and liver cirrhosis had lower energy expenditure and abnormal substrate metabolism. Patients with chronic hepatitis and cirrhosis had a higher protein oxidation rate and a lower carbohydrate oxidation rate compared with acute hepatitis patients.
