Unsuccessful Direct Acting Antiviral Hepatitis C Treatment Among People With HIV: Findings From an International Cohort.

Background: Historically, hepatitis C virus (HCV) was difficult to treat among people with HIV. However, treatment with direct-acting antivirals (DAAs) results in 90%-95% of people being cured. There is a need to understand why a proportion of people are not cured.

Annual hepatitis C testing and positive tests among gay and bisexual men in Australia from 2016 to 2022: a serial cross-sectional analysis of sentinel surveillance data.

Objective: Guidelines recommend annual hepatitis C virus (HCV) testing for gay and bisexual men (GBM) with HIV and GBM prescribed HIV pre-exposure prophylaxis (PrEP). However, there is a limited understanding of HCV testing among GBM. We aimed to examine trends in HCV testing and positivity from 2016 to 2022.

Risk of Primary Incident Hepatitis C Infection Following Bacterial Sexually Transmissible Infections Among Gay and Bisexual Men in Australia From 2016 to 2020.

Background: In Australia, the incidence of hepatitis C virus (HCV) has declined among gay and bisexual men (GBM) with human immunodeficiency virus (HIV) since 2015 and is low among GBM using HIV preexposure prophylaxis (PrEP). However, ongoing HCV testing and treatment remains necessary to sustain this. To assess the potential utility of sexually transmissible infections (STIs) to inform HCV testing among GBM with HIV and GBM using PrEP, we examined the association between bacterial STI diagnoses and subsequent primary HCV infection.

Injecting drug use and hepatitis C virus infection independently increase biomarkers of inflammatory disease risk which are incompletely restored by curative direct-acting antiviral therapy.

Background: Hepatitis C virus (HCV) infections are more prevalent in people who inject drugs (PWID) who often experience additional health risks. HCV induces inflammation and immune alterations that contribute to hepatic and non-hepatic morbidities. It remains unclear whether curative direct acting antiviral (DAA) therapy completely reverses immune alterations in PWID.

A multi-site, nurse-coordinated hepatitis C model of care in primary care and community services in Melbourne, Australia.

Background: Hepatitis C virus (HCV) treatment through primary care and community-based services will be a critical component of HCV elimination. We evaluated a nurse-coordinated programme providing care across eight sites and analysed progression through the HCV care cascade.

Methods: People-accessing services from six primary care clinics, a homeless crisis accommodation provider and a mental health service were directly referred to nurses or engaged by nurses during regular clinic visits.

The Incidence of Hepatitis C Among Gay, Bisexual, and Other Men Who Have Sex With Men in Australia, 2009-2019.

Background: Hepatitis C virus (HCV) infection has been reported among gay, bisexual, and other men who have sex with men (GBM) globally including GBM with human immunodeficiency virus (HIV) and HIV-negative GBM, particularly those using HIV preexposure prophylaxis (PrEP). In Australia, HCV direct-acting antiviral treatment (DAA) was government-funded from 2016. Large implementation studies of PrEP also began in 2016.

It is time for us all to embrace person-centred language for people in prison and people who were formerly in prison.

The use of person-centred language is well accepted regarding substance use and infectious disease healthcare and research, and appropriate acronyms have become commonplace, e.g., "people who inject drugs (PWID)" has mostly replaced phrases like "injecting drugs users".

Patient-reported outcomes of the Treatment and Prevention Study: A real-world community-based trial of direct-acting antivirals for hepatitis C among people who inject drugs.

The impact of hepatitis C cure with direct-acting antivirals (DAAs) on patient-reported outcomes (PROs) in community settings remains unclear. We aimed to assess changes in PROs over time and whether treatment was associated with sustained improved PROs in a cohort of people who inject drugs. This study is a sub-analysis of the Treatment and Prevention Study, a nurse-led trial where people who inject drugs and their injecting partners were recruited in a community setting, in Melbourne, Australia.

Hepatitis C treatment in a co-located mental health and alcohol and drug service using a nurse-led model of care.

Hepatitis C virus (HCV) is more prevalent among people with experience of severe mental illness compared to the general population, due in part to higher levels of injecting drug use. Delivering HCV care through mental health services may reduce barriers to care and improve outcomes. A nurse-led HCV program was established in a co-located mental health and addiction service in Melbourne, Australia.

Microelimination of Hepatitis C Among People With Human Immunodeficiency Virus Coinfection: Declining Incidence and Prevalence Accompanying a Multicenter Treatment Scale-up Trial.

Background: Gay and bisexual men (GBM) are a key population affected by human immunodeficiency virus (HIV) and hepatitis C virus (HCV) coinfection. We aimed to measure HCV treatment effectiveness and to determine the population impact of treatment scale-up on HCV prevalence and incidence longitudinally among GBM.

Methods: The co-EC Study (Enhancing Care and Treatment Among HCV/HIV Coinfected Individuals to Eliminate Hepatitis C Transmission) was an implementation trial providing HCV direct-acting antiviral treatment in Melbourne, Australia, during 2016-2018.

Risk of Subsequent HIV Infection Following Sexually Transmissible Infections Among Men Who Have Sex With Men.

Background: HIV and bacterial sexually transmissible infection (STI) notifications among men who have sex with men (MSM) have increased in Australia and many other countries. The relationship between HIV infection and other STIs has been demonstrated previously. However, the relationship between the cumulative history of STIs and subsequent HIV infection remains largely unexplored and limits our understanding of the mechanisms underpinning the elevated HIV risk.

Quantitative evaluation of an integrated nurse model of care providing hepatitis C treatment to people attending homeless services in Melbourne, Australia.

Background: The prevalence of hepatitis C virus (HCV) has been reported to be high among people experiencing homelessness. People who are homeless often have multiple needs that may take precedence over HCV testing and treatment. We quantitatively evaluated the outcomes of a service providing HCV treatment to people attending homeless services.

An evaluation of the change in activity and workload arising from diabetic ophthalmology referrals following the introduction of a community based digital retinal photographic screening programme.

Aims: To determine how the workload of an ophthalmology department changed following the introduction of an organised retinal screening programme.

Methods: Information was collected from the hospital medical record of people with diabetes attending eye clinics over 4 years. The first year was before screening, the next 2 years the first round, and the fourth year the second round.

The effectiveness of screening for diabetic retinopathy by digital imaging photography and technician ophthalmoscopy.

Aims: To evaluate the introduction of a community-based non-mydriatic and mydriatic digital photographic screening programme by measuring the sensitivity and specificity compared with a reference standard and assessing the added value of technician direct ophthalmoscopy.

Methods: Study patients had one-field, non-mydriatic, 45 degrees digital imaging photography prior to mydriatic two-field digital imaging photography followed by technician ophthalmoscopy. Of these patients, 1549 were then examined by an experienced ophthalmologist using slit lamp biomicroscopy as a reference standard.
