简介：客观干扰素(IFN)和ribavirin(RBV)的联合是为丙肝的标准治疗病毒(HCV)感染。HCV遗传型2a对治疗证明了更顺从，但是它的功效是还有限的。这研究试图在HCV遗传型2a感染的一种情况中调查差的反应的机制。方法：我们从一个病人分析了HCVRNA的动态变化，与HCV遗传型2a感染了，显示出差的virological回答到是的IFN/RBV判定了12在由HCV的治疗的开始以后的星期克隆定序。然后，我们构造了subgenomic日语有人性化的Gaussia的暴发性的hepatitis-1(JFH1)replicon和不同妄想的replicons酶基因。妄想的replicons从subgenomicJFH1replicon，NS5A区域被病人顺序从pre/posttreatment在代替被导出，并且到IFN的妄想的replicons危险性被相对Gausia酶活动评估。预告的处理HCV定序的结果显得几乎一致，并且quasispecies变化是进一步的在12星期治疗以后简化的更多。而且，quasispecies变化似乎相对，在NS5A更多样化为IFN反应关键的一个区域，和每妄想的replicons展出了不同反应到IFN。结论在长期的感染的功课期间，HCV人口似乎被使适应病人免疫学的系统，并且推进被IFN/RBV治疗的联合选择，显示quasispecies可以完全与IFN的与那些不同的目标由另外的药的增加消除了。另外，到IFN的妄想的replicon的各不同的反应与氨基酸变化在或在在长期的感染和IFN/RBV治疗期间决定NS5A的区域(ISDR)的IFN敏感附近有关是最可能的。

简介：AbstractBackground:Hepatitis C virus (HCV) genotype 3, particularly subtype 3b, is increasing in prevalence and distribution in China. This study evaluated the prevalence, regional distribution, clinical characteristics, host factors, treatment outcomes, and disease progression of patients with HCV genotype 3 in China.Methods:A 5-year follow-up was preceded by a cross-sectional study. Treatment choices were at the discretion of treating physicians. Estimated infection time to overall-disease-progression (defined by ≥1 of: newly diagnosed cirrhosis; cirrhosis at baseline, Child-Turcotte-Pugh score increased 2 points or more; progression from compensated cirrhosis to decompensated cirrhosis; hepatocellular carcinoma; liver transplantation; or death) was calculated using the Kaplan-Meier method. Cox regression analyses were conducted to evaluate the risk factors for disease progression.Results:The cross-sectional study enrolled 997 patients, including 91 with HCV genotype 3 infection. Among them, subtype 3b (57.1%) was more dominant than subtype 3a (38.5%). Five hundred and twelve patients were included into the follow-up phase. Among patients analyzed for estimated infection time to overall-disease-progression, 52/304 (17.1%) patients with HCV genotype 1 and 4/41 (9.8%) with HCV genotype 3 (4/26 with genotype 3b, 0/13 with genotype 3a, and 0/2 with undefined subtype of genotype 3) experienced overall-disease-progression. Patients with HCV genotype 3 were younger than those with genotype 1 (mean age: 39.5 ± 8.7 vs. 46.9 ± 13.6 years) and demonstrated more rapid disease progression (mean estimated infection time to overall-disease-progression 27.1 vs. 35.6 years).Conclusions:HCV genotype 3, specifically subtype 3b, is associated with more rapid progression of liver disease. Further analysis to compare HCV subtype 3a and 3b is needed in high prevalence regions.Trial registration:NCT01293279, https://clinicaltrials.gov/ct2/show/NCT01293279; NCT01594554, https://clinicaltrials.gov/ct2/show/NCT01594554.

简介：AbstractBackground:Antiretroviral therapy (ART) has reduced mortality among people living with HIV (PLWH) in China, but co-infections of hepatitis B virus (HBV) and hepatitis C virus (HCV) may individually or jointly reduce the effect of ART. This study aimed to evaluate the impacts of HBV/HCV coinfections on treatment drop-out and mortality among PLWH on ART.Methods:A retrospective cohort study analysis of 58,239 people living with HIV (PLWH) who initiated antiretroviral therapy (ART) during 2010-2018 was conducted in Guangxi Province, China. Data were from the observational database of the National Free Antiretroviral Treatment Program. Cox proportional hazard models were fitted to evaluate the effects of baseline infection of HBV or HCV or both on death and treatment attrition among PLWH.Results:Our study showed high prevalence of HBV (11.5%), HCV (6.6%) and HBV-HCV (1.5%) co-infections. The overall mortality rate and treatment attrition rate was 2.95 [95% confidence interval (CI): 2.88-3.02] and 5.92 (95% CI: 5.82-6.01) per 100 person-years, respectively. Compared with HIV-only patients, HBV-co-infected patients had 42% higher mortality [adjusted hazard ratio (aHR)=1.42; 95% CI 1.32-1.54], HCV-co-infected patients had 65% higher mortality (aHR=1.65; 95% CI: 1.47-1.86), and patients with both HCV and HBV co-infections had 123% higher mortality (aHR=2.23; 95% CI:1.87-2.66).Conclusions:HBV and HCV coinfection may have an additive effect on increasing the risk of all-cause death among PLWH who are on ART. It is suggested that there is need for primary prevention and access to effective hepatitis treatment for PLWH.
