2014年5月12日 訊 /生物谷BIOON/ --近日,刊登在國際雜誌Liver Transplantation上的一篇研究論文中,來自義大利的研究人員通過研究表示,尿乙基葡糖苷酸(uEtG)可以準確檢測肝臟移植候選人和受者機體的究竟消耗,這也就表明尿乙基葡糖苷酸和酒精消耗障礙的鑑別試驗相結合將可以作為醫生對患者進行酒精消耗測定的最佳方法。
酒精性肝病是歐洲和美國常見的肝臟移植原因,有研究預測未來因酒精導致的肝臟移植率將達到49%;實際上醫學研究證據顯示,相比飲酒節制的患者來講,移植失敗的患者往往存在較低的生存率。
來自帕多瓦大學的教授Paolo Angeli表示,評估酒精消耗對於選擇肝臟移植候選者非常關鍵,而且檢測肝臟移植者的酒精飲用情況也非常重要,這將幫助研究者對患者進行早期幹預防止移植的失敗;當前研究中研究者對121個肝臟移植候選者和受者機體中的uEtG、AUDIT-c、血清中乙醇、尿液中乙醇以及碳水化合物缺失轉鐵蛋白進行了評估,用以評估個體的飲酒狀態,參與者需要提供血液和尿液樣本來供研究者檢測其機體中的酒精標記物。
研究者檢測了31%的參與者的酒精消耗量,發現uEtG是一種檢測酒精消耗的較強標記物,而利用uEtG和AUDIT-c結合就可以更為精確地檢測個體的酒精消耗。
最後研究人員表示,利用uEtG和AUDIT-c將可以對移植候選者和受者的酒精情況進行更好地監測,這對於肝臟移植者的移植成功率非常關鍵,也可以防止或者降低移植失敗的風險。(生物谷Bioon.com)

The detection of alcohol consumption in liver transplant candidates (LTCs) and recipients (LTRs) is required to enable a proper assessment of transplant eligibility and an early management of alcohol relapse, respectively. In this clinical setting, urinary ethyl glucuronide (uEtG), the Alcohol Use Disorders Identification Test for alcohol consumption (AUDIT-c), serum ethanol (sETOH), urinary ethanol (uETOH), carbohydrate-deficient transferrin (CDT), and other indirect markers of alcohol consumption were evaluated and compared prospectively in 121 LTCs and LTRs. Alcohol consumption was defined by a positive AUDIT-c or when it was confirmed by patient history in response to his/her abnormal results. Alcohol consumption was found in 30.6% of patients. uEtG was found to be the strongest marker of alcohol consumption (OR=414.5; p<0.0001) and showed a more accurate prediction rate of alcohol consumption when compared to CDT (area under the ROC=0.94 vs 0.63; p<0.0001) and AUDIT-c (AUROC=0.94 vs 0.73;p<0.0001). The combination of uEtG with AUDIT-c showed a higher accuracy in detecting alcohol consumption when compared to the combination of CDT and AUDIT-c (AUROC=0.98 vs 0.80; p<0.001). Furthermore, uEtG was the most useful marker for detecting alcohol consumption in patients with a negative AUDIT-c. In conclusion, the association of AUDIT-c and uEtG improves the detection of alcohol consumption in LTCs and LTRs. Therefore, they should be used routinely in these patients.
