Reviewer #1 comments and responses

Overall: This study from a prospective observational cohort of the International Epidemiology Databases to Evaluate AIDS (IeDEA) Asia-Pacific (TAHOD-LITE) was aimed to assess regional HCV coinfection and cascade outcomes among adults living with HIV in care from 2010-2020 in Asia.

Response: Thank you for your review of our manuscript and recommendations to improve it. We hope these have been adequately addressed in our responses (below) and associated edits.

Comment 1. The proportion of people living with HIV (PLHIV) with a positive anti-HCV test was reported over three time periods that broadly correspond to very limited DAA access (the pre-DAA era), initial DAA access, and expanded DAA access in the Asia-Pacific region: 2010-2014, 2015-2017, and 2018-2020. Results of three time periods should be mentioned in Abstract.

Response: We have added data on the positive anti-HCV test results and HCV cascade proportions from all three of the 2010-2014, 2015-2017, and 2018-2020 time periods to the abstract.

Comment 2. Liver fibrosis, liver function reserve, renal function, HCV genotype and HCV RNA may be factors associated with chronic HCV treatment response. The proportion of liver cirrhosis, liver fibrosis grade, serum albumin, creatinine, HCV genotype and HCV RNA should be analyzed in Table 4.

Response: Thank you for this suggestion to include these additional factors in the chronic HCV treatment response regression analysis. As suggested we did have adequate creatinine data and have added that to the analysis. However, we were either unable to include the other factors or felt it could confuse the findings. We believe that associations between liver cirrhosis and fibrosis and chronic HCV treatment response are likely already covered to an extent by our inclusion of ALT and AST levels. Unfortunately, we did not collect albumin test results from our study participants so cannot add that to the regression analysis. In addition, HCV genotype results are very limited or often not available, particularly from sites in resource-limited countries or countries that use pan-genotypic DAAs and rarely test HCV genotype. Regarding HCV RNA, we expect more HCV RNA testing to be done in later calendar years which would confound with the calendar year variable included. Therefore, instead of including it, HCV RNA has been discussed. Furthermore, inclusion of HCV RNA in our analysis will likely show that high HCV RNA is associated with a reduced hazard for achieving SVR. Table 4 and the associated text in the methods and results sections have been revised to reflect the changes that were made.

Comment 3. Table 2, Calendar year, “2017”-2020 should be “2018”-2020.

Response: Thank you for spotting this error, which we have now corrected.

Additional Editor Comments (if provided):

* Please make a brief discussion about the potential HCV reinfection among PLWH after achieving SVR with antiviral treatment. In Taiwan, a recent study showed that a increasing trend of HCV reinfection among HIV positive patients after the commencement of direct-acting antivirals, which may post a public health treat and should alert the physicians about the post-treatment surveillance based on public health perspectives (Liu CH, et al. Open Forum Infect Dis 2022).

Revision 2

Additional editor comments: Please make a brief discussion about the potential HCV reinfection among PLWH after achieving SVR with antiviral treatment. In Taiwan, a recent study showed that a increasing trend of HCV reinfection among HIV positive patients after the commencement of direct-acting antivirals, which may post a public health treat and should alert the physicians about the post-treatment surveillance based on public health perspectives (Liu CH, et al. Open Forum Infect Dis 2022).

Response: Thank you for the suggestion to add to the discussion the potential for HCV reinfection and the importance of post HCV treatment surveillance among those living with HIV, and for providing an associated reference. The following text was added to the discussion section: “Improved HCV screening and scale-up of HCV treatment are also important for reducing the risk of HCV re-infection amongst PLHIV (56). A recent study of HCV re-infection among an adult PLHIV cohort in Taiwan found that those living with HIV had higher HCV re-infection rates than the HIV-negative reference population, and that HCV reinfection incidence increased following the availability of DAAs in the country, further highlighting the importance of post HCV treatment surveillance among PLHIV (57).” The following references were also added: “56. Hosseini-Hooshyar S, Hajarizadeh B, Bajis S, Law M, Janjua NZ, Fierer DS, et al. Risk of hepatitis C reinfection following successful therapy among people living with HIV: a global systematic review, meta-analysis, and meta-regression. The lancet HIV. 2022;9(6):e414-e27” and “57.
