替诺福韦酯治疗慢性乙型肝炎研究进展简

As a kind of nucleotide drugs, tenofovir disoproxil fumarate （TDF） has been widely used for the treatment of chronic hepatitis B （CHB） in Europe and United States with effective therapeutic results. The clinical studies have demonstrated that TDF is an effective and safe drug for both naive and treatment-experienced CHB patients. The antiviral effect of TDF is superior to adefovir. TDF represses the disease and improves the prognosis for patients with either compensated or decompensated liver diseases due to CHB. For pregnant woman with HBV infections, if necessary, TDF could be used and no evidence of drug-related birth defects have been reported. The adverse events of TDF include headache, fatigue, and etc. In addition, TDF showed few side effects on renal functions and metabolism of calcium and phosphorus; therefore, it can be used for liver transplant recipients and CHB patients with renal deficienely. So far, gene mutations associated with TDF resistance have not been found. TDF provides a new choice of antiviral therapy for CHB patients.     

恩替卡韦治疗慢性乙型肝炎53例疗效分析

目的：评价恩替卡韦治疗慢性乙型肝炎（CHB）12个月的疗效和安全性.方法：选择CHB患者53例给予恩替卡韦0.5 mg/d抗病毒治疗12个月,53例患者治疗前乙型肝炎病毒（HBV）DNA载量分为107～109、105～106、104 copies/L进行分层,分别观察服药后1、3、6、12个月时HBV DNA载量,丙氨酸氨基转氨酶（ALT）、天门冬氨酸氨基转氨酶（AST）变化情况.结果：恩替卡韦对治疗前HBV DNA载量分别为107～109、105～106、104均具有较强的抑制作用;治疗后随着时间推移HBV DNA载量下降越明显,治疗前HBV DNA载量越低服药后HBV DNA载量越快达到正常值,治疗前后差异均有统计学意义（P＜0.05～P＜0.01）.恩替卡韦抑制HBV DNA的同时伴随ALT、AST的下降,治疗前HBV DNA载量越低,治疗后12个月ALT、AST复常率越高,治疗前后差异均有统计学意义（P＜0.05～P＜0.01）.结论：恩替卡韦对CHB患者HBV有很强的抑制作用,在抑制病毒复制的同时能改善肝功能.
