Widespread use of lamivudine in antiretroviral therapy may lead to hepatitis B virus resistance in HIV-HBV coinfected patients from endemic settings where tenofovir is not readily available. We evaluated 389 Kenyan HIV-infected adults before and for 18 months after starting highly active antiretroviral therapy with stavudine, lamivudine and nevirapine. Twenty-seven (6.9%) were HBsAg positive and anti-HBs negative, 24 were HBeAg negative, and 18 had HBV DNA levels ≤ 10,000 IU/mL. Sustained HBV suppression to <100 IU/mL occurred in 89% of 19 evaluable patients. Resistance occurred in only two subjects, both with high baseline HBV DNA levels. Lamivudine resistance can emerge in the setting of incomplete HBV suppression but was infrequently observed among HIV-HBV coinfected patients with low baseline HBV DNA levels.
广泛使用拉米夫定进行抗逆转录病毒治疗可能导致在没有更昔洛韦的流行地区,艾滋病毒 - 乙肝病毒合并感染患者出现乙肝病毒耐药。我们评估了 389 名肯尼亚艾滋病毒感染成年人在开始使用司他夫定、拉米夫定和奈韦拉平进行高效抗逆转录病毒治疗前和治疗后 18 个月的情况。其中 27 人(6.9%)HBsAg 阳性且抗 -HBs 阴性,24 人 HBeAg 阴性,18 人 HBV DNA 水平≤10,000 IU/mL。在 19 名可评估患者中,有 89%的患者持续 HBV 抑制到<100 IU/mL。只有两名患者出现耐药,且两人均具有较高的基线 HBV DNA 水平。拉米夫定耐药可在 HBV 抑制不完全的情况下出现,但在基线 HBV DNA 水平较低的艾滋病毒 - 乙肝病毒合并感染患者中很少观察到。
