| 1 | Vitamin D status and viral response to therapy in hepatitis C infected children显示文摘AIM: To study the frequency of vitamin D deficiency in patients with hepatitis C virus(HCV) infection and to evaluate the role of vitamin D supplementation in improving antiviral therapy.METHODS: Sixty-six children aged from 7-14 years(mean ± SD, 11.17 ± 2.293) diagnosed with HCV infection were matched to 28 healthy controls. Serum levels of 25(OH) D3, calcium, phosphorus, alkaline phosphatase and plasma level of parathormone were measured. Quantitative PCR for HCV was performed Bone density was determined by dual energy X-ray absorptiometry. All cases received conventional therapy, and only 33 patients received vitamin D supplementation.RESULTS: Children with HCV showed significantly increased levels of HCV RNA(P < 0.001), parathormone(P < 0.01) and decreased vitamin D levels(P < 0.05)(33.3% deficient and 43.3% insufficient) compared with controls. Abnormal bone status(Z score-1.98 ± 0.75) was found in ribs, L-spine, pelvis and total body. Cases treated with vitamin D showed significant higher early(P < 0.04) and sustained(P < 0.05) virological response. There was a high frequency of vitamin D deficiency among the Egyptian HCV children, with significant decrease in bone density. The vitamin D level should be assessed before the start of antiviral treatment with the correction of any detected deficiency. CONCLUSION: Adding vitamin D to conventional Peg/RBV therapy significantly improved the virological response and helped to prevent the risk of emerging bone fragility. | Azza A Eltayeb Madleen Adel A Abdou Amal M Abdel-aal Mostafa H Othman | 2015 | World Journal of Gastroenterology2015，21，4： | 3 |
| 2 | Serum vitamin D_3 does not correlate with liver fibrosis in chronic hepatitis C显示文摘AIM: To investigate the relationship between serum vitamin D3 levels and liver fibrosis or inflammation in treatment-naive Chinese patients with chronic hepatitis C(CHC).METHODS: From July 2010 to June 2011, we enrolled 122 CHC patients and 11 healthy controls from Dingxicity, Gansu Province, China. The patients were infected with Hepatitis C virus(HCV) during blood cell retransfusion following plasma donation in 1992-1995, and had never received antiviral treatment. At present, all the patients except two underwent liver biopsy with ultrasound guidance. The Scheuer Scoring System was used to evaluate hepatic inflammation and the Metavir Scoring System was used to evaluate hepatic fibrosis. Twelve-hour overnight fasting blood samples were collected in the morning of the day of biopsy. Serum levels of alanine aminotransferase, aspartate aminotransferase, total bilirubin, direct bilirubin, cholineste rase, prothrom binactivity, albumin, γ-glutamyl transpeptidase, hemoglobin, calcium and phosphorus were determined. Serum HCV RNA levels were measured by real-time PCR. Serum levels of 25-hydroxyvitamin D3 [25(OH)D3] and 24,25-dihydroxyvitamin D3 [24,25(OH)2D3] were measured by high-performance liquid chromatography tandem mass spectrometry.R E S U LT S : Serumlevels of 2 5(OH) D3 but not 24,25(OH)2D3 were significantly lower in CHC patients than in control subjects. Serum 25(OH)D3 levels did not correlate with liver fibrosis, inflammation, patient age, or levels of alanine aminotransferase, aspartate aminotransferase, total bilirubin, direct bilirubin, prothrombin activity, cholinesterase or HCV RNA. However, serum 25(OH)D3 levels did correlate with serum 24,25(OH)2D3 levels. Serum 25(OH)D3 and 24,25(OH)2D3 levels, and the 25(OH)D3/24,25(OH)2D3 ratio, have no difference among the fibrosis stages or inflammation grades.CONCLUSION: We found that serum levels of 25(OH)D3 and its degradation metabolite 24,25(OH)2D3 did not correlate with liver fibrosis in treatment-naive Chinese patient with CHC. | Yan Ren Mei Liu Jing Zhao Feng Ren Yu Chen Jun-Feng Li Jing-Yun Zhang Feng Qu Jin-Lan Zhang Zhong-Ping Duan Su-Jun Zheng | 2015 | World Journal of Gastroenterology2015，21，39： | 2 |
