To examine whether a dose-up to 900 mg of ursodeoxycholic acid (UDCA) decreases transaminases in hepatitis C patients.
From January to December 2007, patients with chronic hepatitis C or compensated liver cirrhosis with hepatitis C virus (HCV) (43-80 years old) showing positive serum HCV-RNA who had already taken 600 mg/d of UDCA were recruited into this study. Blood parameters were examined at 4, 8 and 24 wk after increasing the dose of oral UDCA from 600 to 900 mg/d.
Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and gamma-glutamyl transpeptidase (GGT) levels were significantly decreased following the administration of 900 mg/d as compared to 600 mg/d. The decrease in ALT from immediately before the dose-up of UDCA to 8 wk after the dose-up was 14.3 IU/L, while that for AST was 10.5 IU/L and for GGT was 9.8 IU/L. Platelet count tended to increase after the dose-up of UDCA, although it did not show a statistically significant level (P = 0.05). Minor adverse events were observed in 3 cases, although no drop-outs from the study occurred.
Oral administration of 900 mg/d of UDCA was more effective than 600 mg/d for reducing ALT, AST, and GGT levels in patients with HCV-related chronic liver disease.
研究高达900毫克的熊去氧胆酸(UDCA)是否能降低丙型肝炎患者的转氨酶。
2007年1月至12月,招募年龄在43 - 80岁、血清丙型肝炎病毒(HCV)RNA呈阳性、已服用600毫克/天UDCA的慢性丙型肝炎或代偿性丙型肝炎肝硬化患者进入本研究。在将口服UDCA剂量从600毫克/天增加到900毫克/天后的第4、8和24周检查血液参数。
与600毫克/天相比,服用900毫克/天后血清丙氨酸氨基转移酶(ALT)、天冬氨酸氨基转移酶(AST)和γ-谷氨酰转肽酶(GGT)水平显著降低。从UDCA剂量增加前到剂量增加后8周,ALT下降了14.3国际单位/升,AST下降了10.5国际单位/升,GGT下降了9.8国际单位/升。UDCA剂量增加后血小板计数有增加趋势,尽管未达到统计学显著水平(P = 0.05)。观察到3例轻微不良事件,不过研究中无患者退出。
对于丙型肝炎相关慢性肝病患者,口服900毫克/天的UDCA在降低ALT、AST和GGT水平方面比600毫克/天更有效。
