[摘要] 我国肺结核合并慢性HBV感染者多见,该种患者抗结核治疗可导致HBV再激活,致抗结核治疗的中断、延迟或提前终止,易引起结核播散或耐药。南昌市南昌县人民医院2014年6~7月收治了3例抗结核治疗导致HBV再激活病例,此3例患者在治疗过程中获得相似的疗效,提示接受抗结核药物治疗前抗病毒的重要性,而化疗过程中一旦发生HBV再激活,选择强效、高屏障耐药的抗病毒药物能够迅速降低HBV DNA水平,减轻因HBV再激活导致的肝功能损害,增加有效抗结核治疗的机会。

[Abstract] In China, tuberculosis with chronic HBV patients are more common, hepatitis B virus reactivated during anti-TB therapy will lead to anti-TB treatment interruption, delaying or terminating early, easy causing drug-resistant tuberculosis or disseminated. 3 cases of hepatitis B virus reactivated during anti-TB therapy have been treated in the People's Hospital of Nanchang County in Nanchang City, these 3 patients got the similar treatment effect, that prompts the anti-virus is important before anti-TB treatment, and when hepatitis B virus is reactivated during antituberculosis therapy, selecting potent, high barrier resistant anti-virus drugs can decreases HBV DNA level rapidly, lighten liver function lesion causing by HBV reactivated, increase the chance of effective anti-TB.

我国是结核病发病较高的国家之一,现有结核患者约600万。同时,我国又是乙型肝炎病毒(hepatitis B virus,HBV)的高流行地区,人群中慢性HBV感染为5%~18%,全国约有1.2亿例慢性HBV感染者,故临床上肺结核合并慢性HBV感染者多见。合并慢性HBV感染的结核病的治疗已成为一个不可忽视的课题。异烟肼(H)、利福平(R)、吡嗪酰胺(Z)、乙胺丁醇(E)等作为抗结核治疗的联合用药,被称为抗结核联合化疗方案(anti-tubercolosis combined chemotherapy protocois,ATT)。由于抗结核治疗一般为长期联合用药,药物性肝损害的发生率也相应较高,约为21%。尤其是结核病合并HBV感染患者抗结核治疗所致药物性肝炎的病死率明显增高,该种患者抗结核治疗导致肝功能受损达46%左右[1-3],或可导致HBV再激活。在抗结核治疗的过程中,HBV-DNA升高大于10倍或其绝对值达到1.0×109 copies/mL,并排除其他感染,即可诊断为HBV再激活[4]。对于此类患者,往往致抗结核治疗的中断、延迟或提前终止,易引起结核播散或耐药。……
