RESUMEN
BACKGROUND AND AIMS: Direct-acting antivirals (DAAs) are highly effective in treating hepatitis C. However, there is concern that cure rates may be lower, and reinfection rates higher, among people who inject drugs. We conducted a systematic review of treatment outcomes achieved with DAAs in people who inject drugs (PWID). METHODS: A search strategy was used to identify studies that reported sustained viral response (SVR), treatment discontinuation, adherence or reinfection in recent PWID and/or opioid substitution therapy (OST) recipients. Study quality was assessed using the Newcastle-Ottawa Scale. Meta-analysis of proportions was used to estimate pooled SVR and treatment discontinuation rates. The pooled relative risk of achieving SVR and pooled reinfection rate were calculated using generalized mixed effects linear models. RESULTS: The search identified 8075 references; 26 were eligible for inclusion. The pooled SVR for recent PWID was 88% (95% CI, 83%-92%) and 91% (95% CI 88%-95%) for OST recipients. The relative risk of achieving SVR for recent PWID compared to non-recent PWID was 0.99 (95% CI, 0.94-1.06). The pooled treatment discontinuation was 2% (95% CI, 1%-4%) for both recent PWID and OST recipients. Amongst recent PWID, the pooled incidence of reinfection was 1.94 per 100 person years (95% CI, 0.87-4.32). In OST recipients, the incidence of reinfection was 0.55 per 100 person years (95% CI, 0.17-1.76). CONCLUSIONS: Treatment outcomes were similar in recent PWID compared to non-PWID treated with DAAs. People who report recent injecting or OST recipients should not be excluded from hepatitis C treatment.

OBJECTIVE: It is unclear how often anxiety is diagnosed and treated and whether anxiety treatment is associated with improved viral suppression in persons with HIV. In this study, we characterized the anxiety care continuum and its association with viral suppression in a large urban HIV clinic in the United States. DESIGN: Observational cohort study. METHODS: We described the anxiety care continuum by combining data on self-reported anxiety symptoms, engagement in mental health care, clinical diagnoses and prescriptions from 1,967 persons receiving HIV care and treatment in Baltimore, Maryland, from 2014-23. We examined cross-sectional associations with viral suppression. All analyses were stratified by sex and race/ethnicity; a secondary analysis adjusted for age, years in care, and depressive symptoms. RESULTS: Nearly 1 in 5 patients reported mild-severe symptoms of anxiety but were not currently receiving mental health care or pharmacologic treatment for anxiety; 6% of patients reported anxiety symptoms but were receiving treatment, and 7% had been treated for anxiety that was currently in remission. The prevalence of viral suppression ranged from 87-89% across the anxiety care continuum except among patients with untreated moderate-severe anxiety, only 81% of whom were virally suppressed (95% CI: 80, 83). In adjusted models, untreated moderate-severe anxiety remained associated with viral non-suppression across demographic groups. CONCLUSION: We observed a robust association between untreated anxiety and viral non-suppression in a large urban cohort of persons with HIV. Screening for anxiety may identify patients with unmet mental health care needs who face barriers to maintaining viral suppression.
RESUMEN
AIMS: To estimate the joint effects of substance use disorder (SUD) and recent substance use on human immunodeficiency virus (HIV) non-suppression. DESIGN: Retrospective clinical cohort study with repeated observations within individuals. SETTING: Baltimore, Maryland, United States. PARTICIPANTS: 1881 patients contributed 10 794 observations. MEASUREMENTS: The primary independent variable was the combination of history of SUD and recent substance use. History of SUD was defined as any prior International Classification of Diseases 9/10 code for cocaine or opioid disorder. Recent substance use was defined as the self-report of cocaine or non-prescribed opioid use on the National Institute of Drug Abuse-modified Alcohol, Smoking and Substance Involvement Screening Test or clinician-documented cocaine or opioid use abstracted from the medical record. The outcome was viral non-suppression, defined as HIV RNA >200 copies/mL on the first viral load measurement within 1 year subsequent to each observation of substance use. We adjusted for birth sex, Black race, age, HIV acquisition risk factors, years in care and CD4 cell count. In secondary analyses, we also adjusted for depressive, anxiety and panic symptoms, cannabis use and cannabis use disorder. FINDINGS: On their first observation, 31% of patients had a history of an SUD and 18% had recent substance use. Relative to no history of SUD and no recent substance use, the 1-year fully adjusted risk difference (RD) for viral non-suppression associated with cocaine and opioid use disorder and recent substance use was 7.7% (95% CI = 5.3%-10.0%), the RD was 5.5% (95% CI = 1.2%-9.7%) for history of cocaine use disorder without recent substance use, and the RD was 4.6% (95% CI = 2.7%-6.5%) for recent substance use without a SUD. CONCLUSIONS: Substance use and substance use disorders appear to be highly prevalent among, and independently associated with, viral non-suppression among people with HIV.

Background: The purpose of this study was to identify characteristics of people who respond to two or more overdoses (i.e., multiple overdose responders; MOR) compared to those who respond to zero or one, and the association between MOR status and changes in network size. Methods: Secondary analysis of data from a randomized trial among 199 PWUD in Baltimore, MD (2016-2019). We used cross-tabulation, ð 2 , and ANOVA models to identify cross-sectional associations between overdose response and demographic, drug use, and network size; and ANCOVA models to examine the relationship between baseline MOR status and change in network size. Results: From the cohort of 199, 185 people provided data on overdose response at baseline; 197 provided data at 6-month follow-up. At baseline, 27.6% of participants were classified as MORs (ever). Correlates of MOR status included homelessness; age; injecting drug use; quality of interactions with police (respectful vs. not); and use of powder cocaine, prescription opioids, and heroin. MORs had larger networks and their network size decreased more over time, but the association was not statistically significant. At follow-up, 16% were classified as MORs (past 6 months); correlates of follow-up MOR status were similar to those at baseline. Conclusions: Overdose prevention interventions rely on PWUD to respond to overdoses. Identifying factors associated with MOR status could increase intervention efficiency and providing MORs with support could increase sustainability. Our findings suggest that PWUD experiencing homelessness, using cocaine and heroin, and demonstrating increased salience of overdose in their lives would benefit from targeted programs.
RESUMEN
INTRODUCTION: The availability of safe, effective treatments for hepatitis C virus infection has led to a call for the elimination of hepatitis C, but barriers to care persist. METHODS: In July 2015, the Baltimore City Health Department sexual health clinics began on-site hepatitis C virus treatment. Investigators conducted a retrospective evaluation of the first 2.5 years of this program. Data were extracted from the medical record through June 2019, and data analysis was completed in September 2019. RESULTS: Between July 2015 and December 2017, a total of 560 patients infected with hepatitis C virus accessed care at the Baltimore City Health Department sexual health clinics. Of these patients, 423 (75.5%) were scheduled for hepatitis C virus evaluation at the clinics, 347 (62.0%) attended their evaluation appointment, 266 (47.5%) were prescribed treatment, 227 (40.5%) initiated treatment, and 199 (35.5%) achieved sustained virologic response. Older age was independently associated with hepatitis C virus evaluation appointment attendance (aged 40-59 years: AOR=3.64, 95% CI=1.88, 7.06; aged ≥60 years: AOR=5.61, 95% CI=2.58, 12.21) compared with those aged 20-39 years. Among those who attended hepatitis C virus evaluation appointments, advanced liver disease was independently and positively associated with treatment initiation (AOR=11.89, 95% CI=6.35, 22.25). Conversely, illicit substance use in the past 12 months was negatively associated with hepatitis C virus treatment initiation (AOR=0.49, 95% CI=0.25, 0.96). CONCLUSIONS: The integration of hepatitis C virus testing and on-site treatment in public sexual health clinics is an innovative approach to improve access to hepatitis C virus treatment for medically underserved populations.
