COVID-19 and adults living with chronic hepatitis B

ASHM COVID-19 Taskforce interim recommendations

 

Prepared by members of the Taskforce’s Hepatitis B, CALD and Migrant Populations and Practice Management Cluster Groups and the Taskforce Chair

 

UPDATED ON: 9th April 2020.

Disclaimer: This ASHM document is designed to provide available, relevant information to clinicians and other healthcare providers to optimise the health and wellbeing of people living with chronic hepatitis B during the COVID-19 pandemic. The recommendations provided are the opinions of the authors and are not intended to provide a standard of care, or practice. This document does not reflect a systematic review of the evidence, but will be revised to include relevant future systematic review findings of the National COVID-19 Clinical Evidence Taskforce(1) and other relevant information. 

 

 

In the general community, people over 60 years of age and people with co-morbidities including hypertension, cardiovascular disease, lung disease, cancer, diabetes and chronic liver disease are at greater risk of poorer outcomes with COVID-19 illness(2-6). The Australian Government Department of Health has advised that Aboriginal and Torres Strait Islander people 50 years and older, with one or more chronic medical conditions, may be at greater risk of serious COVID-19 illness. Hence people with chronic hepatitis B who are older and/or have co-morbidities are also likely to be at greater risk of having poorer outcomes with the COVID-19 illness.

Measures to optimise these patients’ health should include supporting smoking cessation, optimising diabetic and blood pressure control. We currently recommend not ceasing or switching away from ACE inhibitors or angiotensin receptor blocker medications: there is not enough evidence that these agents increase the risk of worse outcomes of COVID-19 illness(7) and ceasing or switching these agents may cause harm to otherwise stable patients.  Other key measures include encouraging appropriate exercise, maintaining regular appointments via Telehealth or face-to- face if required, streamlining dispensing of scripts and blood slips, supplying supporting documents for financial assistance and actively referring and encouraging patients to attend Telehealth appointments with medical and allied health specialists. Clinicians should encourage patients to consider Advance Care Planning, as discussed in a recent paper on the clinical presentation and management of COVID-19(8).

A minority of people living with chronic hepatitis B in Australia are receiving guideline-based care(9), and less than a third of those needing antiviral treatment for hepatitis B are currently receiving it(10). Optimising assessment and management of chronic hepatitis B, including initiating antiviral treatment as indicated to prevent progressive liver disease, is important. Further information on the assessment and management of hepatitis B is available at https://www.hepatitisb.org.au/.

For patients who are well including those who are stably virologically suppressed on antiviral therapy, scheduling fewer regular appointments, including Telehealth visits and deferring hepatitis B viral load and other routine blood tests for up to 6 months is reasonable, as is deferring scheduled FibroScan assessments in most circumstances. Surveillance ultrasounds for hepatocellular carcinoma should not be deferred, but consideration should be given to ordering these through community radiology practices if they are usually performed in public hospitals. When surveillance gastroscopies for oesophageal varices in patients with cirrhosis are indicated, these should not be routinely deferred but access to these services is likely to become limited. Discussion with a gastroenterologist/hepatologist is recommended. 

•    All people with chronic hepatitis B should be offered the influenza vaccine
•    People living with cirrhosis are at increased risk of invasive pneumococcal disease and of severe outcomes of influenza infection. Appropriate vaccination can help prevent infections and keep people living with liver disease healthy, and also avert the need for medical care or hospitalisation at a time when the health system may be seriously challenged by COVID-19. 
•    People with chronic liver disease are recommended to receive 3 doses of 23-valent pneumococcal polysaccharide vaccine – one at diagnosis, a 2nd dose at least 5 years later, and a 3rd dose at least 5 years after the 2nd dose or at age 50 years for Aboriginal or Torres Strait Islander people, or 65 years for non-Indigenous people, whichever is later. People with chronic liver disease are also recommended to receive annual influenza vaccine. Further information is available in the Australian Immunisation Handbook - https://immunisationhandbook.health.gov.au/
•    All people with chronic hepatitis B, including young and well patients should be supported to cease smoking, exercise appropriately, optimise their sleep and adhere to the current National Health and Medical Research Council draft recommendations on alcohol intake(11). Note that for patients living with cirrhosis, no level of alcohol intake is considered safe and they should be supported to cease consuming alcohol.

•    Mental health issues may become more common, or more severe during the COVID-19 pandemic
•    Financial insecurity may impede people meeting their hepatitis B healthcare needs and may lead to housing insecurity
•    Domestic violence rates have escalated globally since SARS-CoV-2 emerged
Clinicians are encouraged to use regular appointments to routinely evaluate these issues in all people with chronic hepatitis B and refer to specialists, community nurses, social workers, peer support, community organisations and other appropriate services, as needed. Clinicians should encourage patients to seek help between appointments if these issues arise.

Be aware of current concerns of people with chronic hepatitis B about the COVID-19 pandemic
•    Some culturally and linguistically diverse populations (CALD) report concerns regarding the term’ term ‘social distancing’ and prefer the term ‘physical distancing’
•    CALD populations report concerns about being hospitalised with COVID-19 and having reduced opportunities to use appropriate medical translation services. Clinicians should undertake to optimise appropriate translation services at all opportunities
•    Achieving social distancing and self-quarantine may be impossible in in overcrowded houses, prisons, detention centres and in homeless settings. Clinicians should advocate for their patients with chronic hepatitis B who are experiencing these conditions to receive urgent support to optimise their protection against SARS-CoV-2 infection
•    People with chronic hepatitis B who are prevented from returning to their home countries may be concerned about being able to afford their antiviral treatment in Australia. Clinicians should contact hepatitis peak organisations (see https://www.hepatitisaustralia.com/members-and-supporters) and speciality pharmacists to canvass any currents arrangements and plans to support these patients
•    Medicare Ineligible people are estimated to represent 10% of all people living with chronic hepatitis B in Australia(9)although this is likely to have reduced with current travel and educational restrictions imposed nationally. Those who remain in Australia and who require medical care including hospitalisation as a result of SARS-CoV-2 infection are concerned about incurring high medical costs in some jurisdictions.

There are no data available that demonstrate that hepatitis B antiviral medications can prevent infection with SARS-CoV-2. 

Chronic hepatitis B and risk of SARS-CoV-2 infection and severe COVID-19 illness
It is currently unknown whether being infected with hepatitis B is itself associated with a relative increase in the risk of acquiring SARS-CoV-2 infection, or a relative increase in the risk of worse outcomes with COVID-19 illness. 

Some people with chronic hepatitis B may be at higher risk of SARS-CoV-2 infection and severe COVID-19 illness
Some people with chronic hepatitis B may have a greater level of immunosuppression than others and may be more vulnerable to infection with SARS-CoV-2 and more severe COVID-19 illness. 
We currently suggest that the following patient groups with chronic hepatitis B may be more vulnerable to poorer outcomes with COVID-19 illness because of immunosuppression
•    Those with cirrhosis
•    Those who have had a liver transplant and therein must take life-long immunosuppressive therapy
•    Those with hepatocellular carcinoma.

Early reports on pregnant women with COVID-19 illnesses reveal no maternal deaths, and report that the clinical features and outcomes of COVID-19 illness are not different from non-pregnant women with COVID-19 illness(12-14). Existing evidence suggests people aged under 50 years and females are less likely to have severe outcomes from COVID-19 infection, but more data are awaited to inform the specific situation of pregnant women There has been one report of mother-to-child transmission of the SARS-CoV-2 virus and the neonate developed pneumonia, but recovered fully(13). There are no current data on outcomes of pregnant women with chronic hepatitis B who develop COVID-19 illness and their newborns. Clinicians are advised to seek specialist advice to optimise health outcomes for women with chronic hepatitis B who are seeking to become pregnant, or who are currently pregnant during the COVID-19 pandemic.

People with chronic hepatitis B should receive the same supportive treatment for COVID-19 illness as people without chronic hepatitis B, noting that some people with chronic hepatitis B will be immunosuppressed, have cirrhosis, be older and/or have co-morbidities. It has been hypothesised that non-steroidal medications (NSAIDS) may exacerbate COVID-19 illness, (15) although there is limited evidence to support this. Until more data are available, clinicians might consider using paracetamol for management of symptoms of COVID-19 illness, in preference to use of ibuprofen and other NSAIDS. Specialist medical and pharmaceutical advice should be sought for patients with chronic hepatitis B who are hospitalised with COVID-19 illness. Patients with chronic hepatitis B should be included in all appropriate COVID-19 clinical treatment trials.

All people with chronic hepatitis B are strongly encouraged to adhere to measures that reduce infection with SARS-CoV-2
Note that recommended measures to protect against SARS-CoV-2 infection may vary between jurisdictions, but in all jurisdictions the following measures are critical:
•    Social/physical distancing
•    Regular hand washing
•    Refraining from touching the face 
•    Cough etiquette
•    Social quarantine following contact with person with proven or suspected COVID-19 illness.
