Abstract
BACKGROUND Despite the high prevalence of hepatitis C virus (HCV) among persons living with HIV (PWH), the prevalence of HCV screening, treatment, and sustained virologic response (SVR) is unknown. This study aims to characterize the continuum of HCV screening and treatment among PWH in HIV care. SETTING Adult patients enrolled at 12 sites of the HIV Research Network located in 3 regions of the United States were included. METHODS We examined the prevalence of HCV screening, HCV coinfection, direct-acting antiretroviral (DAA) treatment, and SVR-12 between 2014 and 2015. Multivariate logistic regression was performed to identify characteristics associated with outcomes, adjusted for site. RESULTS Among 29,071 PWH (age 18-87, 74.8% male, 44.4% black), 77.9% were screened for HCV antibodies; 94.6% of those screened had a confirmatory HCV RNA viral load test. Among those tested, 61.1% were determined to have chronic HCV. We estimate that only 23.4% of those eligible for DAA were prescribed DAA, and only 17.8% of those eligible evidenced initiating DAA treatment. Those who initiated treatment achieved SVR-12 at a rate of 95.2%. Blacks and people who inject drugs (PWID) were more likely to be screened for HCV than whites or those with heterosexual risk. Persons older than 40 years, whites, Hispanics, and PWID [adjusted odds ratio (AOR) 8.70 (7.74 to 9.78)] were more likely to be coinfected than their counterparts. When examining treatment with DAA, persons older than 50 years, on antiretroviral therapy [AOR 2.27 (1.11 to 4.64)], with HIV-1 RNA <400 [AOR 2.67 (1.71 to 4.18)], and those with higher Fib-4 scores were more likely to be treated with DAA. CONCLUSIONS Although rates of screening for HCV among PWH are high, screening remains far from comprehensive. Rates of SVR were high, consistent with previously published literature. Additional programs to improve screening and make treatment more widely available will help reduce the impact of HCV morbidity among PWH.

Abstract
BACKGROUND Direct-acting antivirals (DAAs) against hepatitis C virus (HCV) have been described as revolutionary. However, it remains uncertain how effective these drugs will be for individuals coinfected with human immunodeficiency virus (HIV)-HCV. Bridging this gap between efficacy and effectiveness requires a focus on the generalizability of clinical trials. METHODS Generalizability of DAA trials was assessed by applying the eligibility criteria from 5 efficacy trials: NCT01479868, PHOTON-1 (NCT01667731), TURQUOISE-I (NCT01939197), ION-4 (NCT02073656), and ALLY-2 (NCT02032888) that evaluated simeprevir; sofosbuvir; ombitasvir, paritaprevir/ritonavir/dasabuvir; sofosbuvir/ledipasvir; and daclatasvir/sofosbuvir, respectively, to the Canadian Coinfection Cohort, representing approximately 23% of the total coinfected population in care in Canada. RESULTS Of 874 active participants, 70% had chronic HCV, of whom 410, 26, 94, and 11 had genotypes 1, 2, 3, and 4, respectively. After applying trial eligibility criteria, only 5.9% (24/410) would have been eligible for enrollment in the simeprevir trial, 9.8% (52/530) in PHOTON-1, 6.3% (26/410) in TURQUOISE-I, and 8.1% (34/421) in ION-4. The ALLY-2 study was more inclusive; 43% (233/541) of the cohort would have been eligible. The most exclusive eligibility criteria across all trials with the exception of ALLY-2 were restriction to specific antiretroviral therapies (63%-79%) and active illicit drug use (53%-55%). CONCLUSIONS DAA trial results may have limited generalizability, since the majority of coinfected individuals were not eligible to participate. Exclusions appeared to be related to improving treatment outcomes by not including those at higher risk of poor adherence and reinfection--individuals for whom real-world data are urgently needed.

Abstract
BACKGROUND HCV has a high replication rate and a lack of proofreading activity, leading to a greatly diverse viral population. This diversity may lead to emergence of resistant strains in direct-acting antiviral therapy. The frequency of naturally occurring HCV protease inhibitor (PI) mutations has been addressed in many countries, but there are few data on the prevalence of these mutations in Brazilian patients. METHODS We evaluated the sequence of HCV NS3 protease gene in 247 patients (135 HCV-monoinfected and 112 HIV-HCV-coinfected patients). HCV RNA was extracted from plasma and a fragment of 765 base pairs from the NS3 region was amplified and sequenced with Sanger-based technology. RESULTS HIV-HCV-coinfected patients were more likely to be older than 40 years and have an HCV subtype-1a infection. Overall, 21.9% of patients had at least one amino acid substitution in the NS3 region; 14 patients (5.7%) harboured at least one resistance mutation (T54S, V55A, Q80R) and the Q80K mutation was not found in our case series. There was no difference between monoinfected and coinfected patients regarding the frequency of natural polymorphisms and resistance mutations. CONCLUSIONS Baseline HCV NS3 amino acid substitutions identified herein are considered mostly natural polymorphisms with no clinical impact on PI-based therapy. The identified resistance mutations may be associated with low-level resistance to PIs in vitro. Q80K substitution seems to be a rare event in Brazil. HIV coinfection was not associated with a greater frequency of such substitutions in the studied sample.

Abstract
BACKGROUND With the advent of effective antiretroviral treatment, the life expectancy for people with HIV is now approaching that seen in the general population. Consequently, the relative importance of other traditionally non-AIDS-related morbidities has increased. We investigated trends over time in all-cause mortality and for specific causes of death in people with HIV from 1999 to 2011. METHODS Individuals from the Data collection on Adverse events of anti-HIV Drugs (D:A:D) study were followed up from March, 1999, until death, loss to follow-up, or Feb 1, 2011, whichever occurred first. The D:A:D study is a collaboration of 11 cohort studies following HIV-1-positive individuals receiving care at 212 clinics in Europe, USA, and Australia. All fatal events were centrally validated at the D:A:D coordinating centre using coding causes of death in HIV (CoDe) methodology. We calculated relative rates using Poisson regression. FINDINGS 3909 of the 49,731 D:A:D study participants died during the 308,719 person-years of follow-up (crude incidence mortality rate, 12.7 per 1000 person-years [95% CI 12.3-13.1]). Leading underlying causes were: AIDS-related (1123 [29%] deaths), non-AIDS-defining cancers (590 [15%] deaths), liver disease (515 [13%] deaths), and cardiovascular disease (436 [11%] deaths). Rates of all-cause death per 1000 person-years decreased from 17.5 in 1999-2000 to 9.1 in 2009-11; we saw similar decreases in death rates per 1000 person-years over the same period for AIDS-related deaths (5.9 to 2.0), deaths from liver disease (2.7 to 0.9), and cardiovascular disease deaths (1.8 to 0.9). However, non-AIDS cancers increased slightly from 1.6 per 1000 person-years in 1999-2000 to 2.1 in 2009-11 (p=0.58). After adjustment for factors that changed over time, including CD4 cell count, we detected no decreases in AIDS-related death rates (relative rate for 2009-11 vs 1999-2000: 0.92 [0.70-1.22]). However, all-cause (0.72 [0.61-0.83]), liver disease (0.48 [0.32-0.74]), and cardiovascular disease (0.33 [0.20-0.53) death rates still decreased over time. The percentage of all deaths that were AIDS-related (87/256 [34%] in 1999-2000 and 141/627 [22%] in 2009-11) and liver-related (40/256 [16%] in 1999-2000 and 64/627 [10%] in 2009-11) decreased over time, whereas non-AIDS cancers increased (24/256 [9%] in 1999-2000 to 142/627 [23%] in 2009-11). INTERPRETATION Recent reductions in rates of AIDS-related deaths are linked with continued improvement in CD4 cell count. We hypothesise that the substantially reduced rates of liver disease and cardiovascular disease deaths over time could be explained by improved use of non-HIV-specific preventive interventions. Non-AIDS cancer is now the leading non-AIDS cause and without any evidence of improvement.

Abstract
Liver disease is currently one of the leading causes of hospitalization and death in HIV-positive individuals. Coinfection with the hepatitis C virus (HCV) is a major contributor to this trend. Besides hepatic damage, which is enhanced in the presence of HIV-associated immunosuppression, HCV may contribute to disease in coinfected individuals by potentiating immune activation and chronic inflammation, which ultimately account for an increased risk of cardiovascular events, kidney disease, and cancers in this population. Fortunately, hepatitis C therapeutics has entered a revolutionary era in which we hope that most patients treated with the new oral direct-acting antivirals (DAA) will be cured. However, many challenges preclude envisioning a prompt elimination of HCV from the coinfected population. Issues that should be addressed include the following: (1) rising incidence of acute hepatitis C in men who have sex with men, and expansion/recrudescence of injection drug use in some settings/regions; (2) adverse drug interactions between antiretrovirals and DAA; and (3) high cost of DAA, which may lead many to defer or fail to access appropriate therapy.
