合并丙肝不影响艾滋病抗病毒疗效 处在丙肝活跃期的艾滋病患者服用奈韦拉平更易发生皮疹和肝毒性等副反应

本报讯 (特约记者段文利)我国学者研究发现,合并丙肝并不影响艾滋病患者鸡尾酒治疗的效果,但处在丙肝活跃期的艾滋病患者服用奈韦拉平更易发生皮疹和肝毒性等副反应。这一发现解决了目前国际上关于丙肝病毒是否影响艾滋病疗效的纷争,并提示该类患者的用药禁忌。该研究结果今年4月发表在国际著名的《艾滋病杂志》上。
艾滋病患者合并丙肝后,其抗逆转录病毒治疗的效果是否受丙肝病毒的影响,此前国际上一直存在争议。中国艾滋病患者合并丙肝发生率高达39%,高于国外的30%。既往研究也发现丙肝患者合并艾滋病后病程明显加快,丙肝治疗的效果不理想。因此,观察丙肝与艾滋病之间的关系在发展中国家更具现实意义。
北京协和医院感染科李太生教授等,于2005年至2007年期间开展了全国多中心研究。课题组将175名艾滋病患者分为3组:第一组为丙肝抗体阴性的117名艾滋病患者,第二组为处在丙肝病毒稳定期(丙肝抗体阳性但病毒载量阴性)的24名艾滋病患者,第三组为处在丙肝活跃期(丙肝抗体及丙肝病毒均为阳性)的34名艾滋病患者。课题组对全部研究对象均采用含奈韦拉平的高效联合抗逆转录病毒治疗,并连续随访100周,结果发现上述3组对象在各随访点的CD4+T淋巴细胞、CD8+T淋巴细胞、HIV病毒载量及免疫重建规律等方面均无显著差异,证实了合并丙肝病毒感染的艾滋病患者接受抗逆转录病毒治疗的效果并不受丙肝病毒的影响。
研究同时还在国际上率先证实,处在丙肝活跃期的、丙肝病毒抗体及丙肝病毒均为阳性的艾滋病患者,发生皮疹及肝毒性等副反应的几率明显高于对照组。
李太生介绍说,奈韦拉平因易引发皮疹和肝毒性等副反应,发达国家已经不再将其作为首选药物推荐使用。但该药因疗效确切、价格便宜,目前仍为我国艾滋病抗病毒治疗的一线药物,专家推荐的两种优选配伍方案中均含有奈韦拉平。如果放弃使用奈韦拉平,将使中国政府每年在艾滋病药物治疗方面的投入从20亿元直升至80亿元。因此,这一研究结果对发展中国家的艾滋病治疗具有重要的卫生经济学价值。

合併丙肝不影響艾滋病抗病毒療效處在丙肝活躍期的艾滋病患者服用奈韋拉平更易發生皮疹和肝毒性等副反應

Combined hepatitis C virus does not affect the efficacy of anti-HIV activity of hepatitis C in HIV patients taking nevirapine were more susceptible to skin rashes and liver toxicity and other side effects

NEW YORK (special correspondent Duan Li) our study found that the merger does not affect hepatitis C treatment for AIDS cocktail effect, but in hepatitis C patients with active stage of AIDS are more likely to take nevirapine rash and liver toxicity and other side effects. This finding solves the international impact of HIV on hepatitis C virus effect of the dispute, and prompted such drugs in patients with contraindications. The results of the study published in April this year, the international famous "HIV Medicine" on.
AIDS patients with hepatitis C, its effect of antiretroviral therapy is affected by the hepatitis C virus, had been controversial internationally. China AIDS patients with hepatitis C incidence as high as 39%, higher than 30% foreign. Previous studies also found that patients with AIDS, hepatitis C significantly accelerated after the course, hepatitis C treatment are not ideal. Therefore, the observed relationship between hepatitis C and AIDS in developing countries is more practical significance.
Beijing Union Medical College Hospital Department of Infectious Diseases Professor Li Taisheng, etc., in the period from 2005 to 2007 carried out a national multi-center study. Discussion group to 175 AIDS patients were divided into 3 groups: the first group of 117 HCV antibody-negative AIDS, hepatitis C virus in the second group was stable (HCV antibody positive but negative for viral load) of 24 AIDS patients, the third group was in active phase of hepatitis C (HCV antibody and hepatitis C virus were positive) of 34 AIDS patients. Discussion group on all subjects are used with nevirapine in highly active antiretroviral therapy, and continuous follow-up 100 weeks, results showed that the 3 groups were followed up for an object point in the CD4 + T lymphocytes, CD8 + T lymphocytes, HIV viral load and immune reconstitution in regulation and so there was no significant difference, confirming the merger of hepatitis C virus infection in AIDS patients on antiretroviral therapy results were not affected by hepatitis C virus.
The study also is also the world's first confirmed in an active phase of hepatitis C, hepatitis C virus antibody and hepatitis C virus were positive for AIDS patients, skin rash and liver toxicity was significantly higher chance of side effects.
Intertranslation explained that nevirapine for easily cause rashes and liver toxicity, side effects, the developed countries no longer be recommended as the drug of choice. However, because the drug is effective, cheap and AIDS in China at present is still first-line antiretroviral treatment drugs, experts recommended two preferred programs are compatible with nevirapine. If you abandon the use of nevirapine, the Chinese government will make AIDS drug treatment each year from 2 billion yuan direct investment rose to 8.0 billion. Therefore, this study on AIDS treatment in developing countries has important health economic value.
