Abstract
BACKGROUND Direct-acting antivirals (DAAs) for hepatitis C treatment in China became available since 2017. This study expects to generate evidence to inform decision-making in a nationwide scale-up of DAA treatment in China. METHODS We described the number of standard DAA treatment at both national and provincial levels in China from 2017 to 2021 based on the China Hospital Pharmacy Audit (CHPA) data. We performed interrupted time series analysis to estimate the level and trend changes of the monthly number of standard DAA treatment at national level. We also adopted the latent class trajectory model (LCTM) to form clusters of the provincial-level administrative divisions (PLADs) with similar levels and trends of number of treatment, and to explore the potential enablers of the scale-up of DAA treatment at provincial level. RESULTS The number of 3-month standard DAA treatment at national level increased from 104 in the last two quarters of 2017 to 49,592 in the year of 2021. The estimated DAA treatment rates in China were 1.9% and 0.7% in 2020 and 2021, which is far below the global target of 80%. The national price negotiation at the end of 2019 resulted in DAA inclusion by the national health insurance in January 2020. In that month, the number of treatment increased 3668 person-times (P < 0.05). LCTM fits the best when the number of trajectory class is four. PLADs as Tianjin, Shanghai and Zhejiang that had piloted DAA price negotiations before the national negotiation and that had explored integration of hepatitis service delivery with prevention and control programme of hepatitis C within the existing services demonstrated earlier and faster scale-up of treatment. CONCLUSIONS Central negotiations to reduce prices of DAAs resulted in inclusion of DAA treatment under the universal health insurance, which are critical elements that support scaling up access to hepatitis C treatment in China. However, the current treatment rates are still far below the global target. Targeting the PLADs lagged behind through raising public awareness, strengthening capacity of the healthcare providers by roving training, and integrate prevention, screening, diagnosis, treatment and follow-up management of hepatitis C into the existing services are needed.

Abstract
Pregnant women infected with HCV should be given attention due to their special physiological stage and the effect on offspring health. To examine the prevalence of HCV infection among pregnant women in part of China and explore relevant factors during pregnancy, a cross-sectional study was conducted in four maternal and children health care institutions (MCHC) in Guangdong, Hunan and Chongqing. Pregnant women who were delivered, induced or spontaneous abortion were included and relevant information was collected through the Hospital Information System. Results showed that the prevalence of HCV among pregnant women in four MCHCs was 0.11% (95% CI 0.09-0.13%). Age, occupations, regions, syphilis-infection, intrahepatic cholestasis of pregnancy (ICP), and placenta previa were significant factors (all P < 0.05). Age and syphilis-infection were positively correlated with HCV infection (Z = 3.41, P = 0.0006; OR = 18.16, 95% CI 9.34-35.29). HCV and HBV infection were risk factors of ICP (OR = 4.18, 95% CI 2.18-8.04; OR = 2.59, 95% CI 2.31-2.89). Our study indicates that the prevalence of HCV among pregnant women in the three provinces(city) was low compared with the general population in China. Older age and syphilis-infection increased the risk of HCV infection during pregnancy. HCV infection was a risk factor of ICP. Generally, we need keep a watchful eye on HCV infection and relevant factors mentioned above during pregnancy in clinic, especially those also infected with syphilis. HCV testing based on risk factors is recommended in antenatal care and obstetrics.

Abstract
Objective To investigate the prevalence of hepatitis C virus (HCV) infection among hemodialysis (HD) patients in Lanzhou of Northwestern China, we interviewed 565 patients from five randomly sampled HD centers in Lanzhou with a structured questionnaire including sociodemographic characteristics, past medical history and HD-related factors. Methods The testing results of anti-HCV and HCV-RNA in a recent HD from clinical information system were collected. A generalized estimated equation (GEE) logistic regression model was used to identify the determinants of HCV infection among HD patients. Results The prevalence of anti-HCV or HCV-RNA infection among HD patients was 1.77% or 1.42% respectively. GEE model showed that history of kidney transplantation (HCV-RNA: OR=19.79, 95%CI: 12.69–30.85) could dramatically increase the risk of current HCV infection in dialysis patients. Compared with never using of blood products, using of blood products (anti-HCV: OR=2.38, 95%CI: 1.22–4.64; HCV-RNA: OR=15.23, 95%CI: 1.79–129.49) could increase the risk of HCV infection in dialysis patients. Moreover, with the increase of HD duration, the risk increased one time or so (anti-HCV: OR=1.83, 95%CI: 1.22–2.72; HCV-RNA: OR=2.00, 95%CI: 1.11–3.61). Furthermore, dialysis in multiple hospitals possessed more than three times risk of HCV infection (anti-HCV: OR=3.56, 95%CI: 3.11–4.08; HCV-RNA: OR=3.35, 95%CI: 1.88–5.96). Besides, HD patients having the history of acupuncture (HCV-RNA: OR=5.56; 95%CI: 1.16–26.67) or surgery (HCV-RNA: OR=6.39; 95%CI: 2.86–14.29) caused an about-six-times risk of current infections. Conclusion It could be concluded that the prevalence of HCV infection was mild and using of blood products or kidney transplantation, long dialysis duration, dialysis in multiple hospitals, surgery or acupuncture treatment were some risk factors of HCV infection among HD patients in Lanzhou of Northwestern China.

Abstract
BACKGROUND This review aimed to identify hepatitis C virus (HCV) prevalence estimates among the general population and six key populations (people who inject drugs, men who have sex with men, sex workers, prisoners/detainees, Indigenous people, and migrants) in the World Health Organization Western Pacific Region (WHO WPR). METHODS Original research articles published between 2016 and 2020 were identified from bibliographic databases. Publications were retrieved, replicas removed, and abstracts screened. Retained full texts were assessed and excluded if inclusion criteria were not met. Methodological quality was assessed using the Johanna Briggs Institute critical appraisal checklist for prevalence data. Data on HCV exposure and active infection were extracted and aggregated and forest plots generated for each population by country. RESULTS There were no HCV prevalence estimates in any population for more than half of WPR countries and territories. Among the 76 estimates, 97% presented prevalence of exposure and 33% prevalence of active infection. General population viraemic prevalence was 1% or less, except in Mongolia. Results confirm the endemic nature of HCV among people who inject drugs, with estimates of exposure ranging from 30% in Cambodia to 76% in Hong Kong. CONCLUSIONS Countries require detailed knowledge of HCV prevalence in diverse populations to evaluate the impact of efforts to support WHO HCV elimination goals. Results provide baseline estimates from which to monitor and evaluate progress and by which to benchmark future elimination efforts.

Abstract
Hepatitis C virus (HCV) genotype (GT)3 infection is associated with a more rapid hepatic disease progression than the other genotypes. Hence, early HCV clearance slows down the disease progression and is important for improving prognosis in GT3-infected patients. Nevertheless, compared with other genotypes, GT3 is difficult-to-treat with direct-acting antivirals, especially in the presence of cirrhosis. Current guidelines recommend several regimens which have been proven to be effective in GT3-infected patients from the Western world (North America, Europe, and Oceania). In China, GT3 infection comprises 8.7-11.7% of the 10 million patients infected with HCV and has strikingly different characteristics from that in Western countries. Unlike the Western countries, where GT3a is the predominant subtype, GT3a and 3b each affect roughly half of Chinese GT3-infected patients, with 94-96% of the GT3b-infected patients carrying A30K+L31M double NS5A resistance-associated substitutions. Phase 3 clinical trials including GT3b-infected patients have suggested that GT3b infection is difficult to cure, making the regimen choice for GT3b-infected patients an urgent clinical gap to be filled. This review includes discussions on the epidemiology of HCV GT3 in China, recommendations from guidelines, and clinical data from both Western countries and China. The aim is to provide knowledge that will elucidate the challenges in treating Chinese GT3-infected patients and propose potential solutions and future research directions.
