The serum vaspin levels are reduced in Japanese chronic hemodialysis patients.

ABSTRACT: BACKGROUND: Visceral adipose tissue-derived serine proteinase inhibitor (vaspin) is an adipokine identified in genetically obese rats that correlates with insulin resistance and obesity in humans. Recently, we found that 7% of the Japanese population with the minor allele sequence (A) of rs77060950 exhibit higher levels of serum vaspin. We therefore evaluated the serum vaspin levels in Japanese chronic hemodialysis patients. METHODS: Healthy Japanese control volunteers (control; n = 95, 49.9 ± 6.91 years) and Japanese patients undergoing hemodialysis therapy (HD; n = 138, 51.4 ± 10.5 years) were enrolled in this study, and serum samples were subjected to the human vaspin RIA system. RESULTS: The measurement of the serum vaspin levels demonstrated that a fraction of control subjects (n = 5) and HD patients (n = 11) exhibited much higher levels (> 10 ng/ml; Vaspin High group), while the rest of the population exhibited lower levels (< 3 ng/ml; Vaspin Low group). By comparing the patients in the Vaspin Low group, the serum vaspin levels were found to be significantly higher in the control subjects (0.87 ± 0.24 ng/ml) than in the HD patients (0.32 ± 0.15 ng/ml) (p < 0.0001). In the stepwise regression analyses, the serum creatinine and triglyceride levels were found to be independently and significantly associated with the vaspin concentrations in all subjects. CONCLUSIONS: The creatinine levels are negatively correlated with the serum vaspin levels and were significantly reduced in the Japanese HD patients in the Vaspin Low group.

Project description:BackgroundSerum 25-hydroxyvitamin D3 levels are generally lower in chronic hepatitis C patients than in healthy individuals. The purpose of this study is to clarify the factors which affect serum 25-hydroxyvitamin D3 levels using data obtained from Japanese chronic hepatitis C patients.MethodsThe subjects were 619 chronic hepatitis C patients. Serum 25-hydroxyvitamin D3 levels were measured by using double-antibody radioimmunoassay between April 2009 and August 2014. Serum 25-hydroxyvitamin D3 levels of 20 ng/mL or less were classified as vitamin D deficiency, and those with serum 25-hydroxyvitamin D3 levels of 30 ng/mL or more as vitamin D sufficiency. The relationship between patient-related factors and serum 25-hydroxyvitamin D3 levels was analyzed.ResultsThe cohort consisted of 305 females and 314 males, aged between 18 and 89 years (median, 63 years). The median serum 25-hydroxyvitamin D3 level was 21 ng/mL (range, 6-61 ng/mL). On the other hand, the median serum 25-hydroxyvitamin D3 level in the healthy subjects was 25 ng/mL (range, 7-52), being significantly higher than that those in 80 chronic hepatitis C patients matched for age, gender, and season (p = 1.16 × 10(-8)). In multivariate analysis, independent contributors to serum 25-hydroxyvitamin D3 deficiency were as follows: female gender (p = 2.03 × 10(-4), odds ratio = 2.290, 95 % confidence interval = 1.479-3.545), older age (p = 4.30 × 10(-4), odds ratio = 1.038, 95 % confidence interval = 1.017-1.060), cold season (p = 0.015, odds ratio = 1.586, 95 % confidence interval = 1.095-2.297), and low hemoglobin level (p = 0.037, odds ratio = 1.165, 95 % confidence interval = 1.009-1.345). By contrast, independent contributors to serum 25-hydroxyvitamin D3 sufficiency were male gender (p = 0.001, odds ratio = 3.400, 95 % confidence interval = 1.635-7.069), warm season (p = 0.014, odds ratio = 1.765, 95 % confidence interval = 1.117-2.789) and serum albumin (p = 0.016, OR = 2.247, 95 % CI = 1.163-4.342).ConclusionsSerum 25-hydroxyvitamin D3 levels in chronic hepatitis C Japanese patients were influenced by gender, age, hemoglobin level, albumin and the season of measurement.
