Progress towards the elimination of hepatitis C is being undermined by a lack of attention to the harm reduction
needs of people cured of hepatitis C in the United Kingdom, as well as a lack of testing and
surveillance for reinfection, a report by the Hepatitis C Trust and HCV Action
concludes.
The report recommends that more attention needs to be paid
to detecting reinfection in order to achieve hepatitis C elimination targets,
as well as improving prevention measures for those who have completed a course
of treatment.
Reframing reinfection: towards sustainable hepatitis C elimination in the UK was published by the Hepatitis
C Trust, the national peer support organisation for people with hepatitis C,
and HCV Action, the voice of the hepatitis C professional community. The
Hepatitis C Trust and HCV Action researchers interviewed Operational Delivery Network
staff, people providing peer support services and people recently treated for
hepatitis C, to gain insights into service provision and unmet needs.
The report highlights the patchy evidence regarding reinfection
rates. Although the national Health Security Agency has estimated that almost
11% of people who use drugs in England may have been reinfected after being cured
of hepatitis C, the true extent of reinfection is unclear. Some areas have observed rates as high as 19% within two years of cure, the report authors learned.
Several professionals interviewed for the report stressed
that detecting reinfection is a sign that resources are being used effectively
to screen people at higher risk of hepatitis C infection and re-engage them in
care.
“If you are not seeing reinfections, you are not testing enough,
you are not treating the right people,” Professor John Dillon of Tayside
University, Dundee, told the report’s authors. “Reinfection is an absolute expected
event in a move towards elimination.”
Reinfection should not be used as a reason to deny or delay
treatment, interviewees stressed.
“I think that access to re-treatment is really important for
that group because they are at particular risk of hepatitis C transmission and
therefore potentially may be transmitting to others as well, so treating them
has a network effect,” Dr Stuart Flanagan of London’s Mortimer Market Centre
told the report authors.
The report recommends a greater focus on the provision of
harm reduction services, especially needle and syringe programmes, bespoke harm
reduction for chemsex and provision of injecting equipment and naloxone for
overdose prevention at prison exit. Innovative ways of providing sterile
injecting equipment should be explored, including vending machines, postal
delivery, and provision of overdose prevention centres to support early
engagement with drugs and hepatitis services.
Models for the delivery of harm reduction during and after
hepatitis C treatment are also needed, especially support to reduce injecting,
obtain sterile injecting equipment, and engage in opioid substitution
treatment.
The report also emphasises the need to make more of the
opportunity that hepatitis C treatment brings for addressing other needs of
people with hepatitis C, such as housing and mental health, during and after
the completion of treatment. The six-month pre-treatment and treatment period
is an important opportunity to educate people about reinfection risks and harm
reduction measures and ensure that they have the support in place to minimise
the risk of reinfection after completing treatment.
Ensuring that regular testing is offered after treatment for
people at ongoing risk of reinfection will be critical, the report notes.
“If one in ten people are reinfecting, that we know about, then
how many others do we not know about?”, asked Dr Stuart McPherson of Newcastle
Hospitals NHS Foundation Trust. “It’s a marker that we are further away from
elimination in our region than we maybe think we are.”
Reinfections may be identified more readily in people subject to
more frequent testing, such as people on remand or in prison. But others may be
missed entirely due to lack of contact with services or a failure to offer
testing to people who consider themselves cured of hepatitis C.
Along with testing, surveillance for reinfection must
improve, in order to establish an accurate national picture of reinfection
rates and who is at greater risk of reinfection and to tailor local services.
