摘 要:目的观察替比夫定(LdT)治疗慢性乙型肝炎过程中肌酸激酶(CK)升高情况及预后。方法对2004年2月-2010年2月接受LdT治疗的49例慢性乙型肝炎患者的CK结果进行评估,其中LdT初治患者35例,拉米夫定(LAM)治疗2年后改用LdT继续治疗1~3年患者14例(中间无间隔)。LdT用药时间1~5年。治疗期间每8~12周随访1次,评估项目包括血清HBVDNA、血清HBV标志物、血清生物化学指标(包括CK)、血液学指标,并记录不良事件和合并用药。结果IdT治疗中,随访1、2、3、4、5年的过程中,CK1~4级升高总累积发生率分别为61.2%(30/49)、81.6%(40/49)、87.8%(43/49)、91.8%(45/49)、95.%(47/49),CK1—2级升高累积发生率分别为57.1%(28/49)、73.5%(36/49)、75.5%(37/49)、77.6%(38/49)、81.8%(40/49),CK3~4级累积发生率分别为4.1%(2/49)、12.20/0(6/49)、12.2%/0(6/49)、14.3%(7/49)、14.3%(7/49),第2年CK3级以上年发生率最高(14.3%)。7例患者出现8例次3级以上CK升高,见于36~168周,其中6例患者发生于52~104周,CK最高达正常上限的35.8倍;4例3级以上CK升高患者有诱因存在,去除诱因、继续用药,CK多于2~3周下降至3级以下或正常,无肌力改变。1例LdT初治患者因CK升高〉7×ULN而终止治疗;1例LdT初治患者因CK升高至1096U/L且出现肌无力而终止治疗;1例LAM经治患者因诊断肌病停止治疗。结论CK升高不能作为停药的依据,需结合患者临床表现综合判断。Objective To evaluate the occurrence and prognosis of telbivudine (LdT) therapy- associated elevations in creatine kinase (CK) in chronic hepatitis B (CHB) patients. Methods Forty-nine patients treated with LdT from 2004 to 2010 were evaluated for development of CK elevation. In particular, the occurrences of grade 3/4 CK elevations (7-times the upper limit of normal (ULN)) and muscle damage were assessed over duration of the LdT treatment. Results The rate of CK elevation increased with duration of LdT treatment (1 year: 61.2%; 5 years: 95.9%). In addition, the severity of CK elevation showed a trend for increasing with duration of LdT treatment, with grade 1/2 CK elevations increasing from 57.1% at year 1 to 81.6% at year 5 and grade 4 increasing from 4.1% at year 1 to 14.3% at year 5. Grade 3/4 CK elevations were observed in seven patients between LdT treatment weeks 36 and 168, but occurred most frequently between weeks 52 and 104, when the maximum peak value occurred (35.8-times the ULN). LdT treatment was stopped in two patients due to excessive CK elevation and one patient due to myositis. The majority of eases of LdT-associated grade 3/4 CK elevations were self-limiting, transient (decreasing to grades 0 or 2 within 2-3 weeks), and present without myalgia. Conclusion Elevation of CK was not rare in CHB patients treated with LdT, but most cases resolved spontaneously. In general, the severity and persistence of CK elevation was not sufficient to warrant withdrawal of LdT.
