Marie Faughnan, M.D., M.Sc – Director, Toronto HHT Centre of Excellence Director

There is currently no research or evidence related to how people with hereditary hemorrhagic telangiectasia (HHT) experience COVID infection. In addition to the issues brought about by nosebleeds including increased touching of the face, Dr. Faughnan has compiled a list of conditions that may increase the risk of becoming very sick once an HHT patient becomes infected with COVID-19. Based on population reports and also knowledge of typical chronic disease factors that predispose to viral infections and pneumonia, the suspected risk factors for HHT patients are detailed below:

Having these conditions MAY increase the risk in people with HHT who have contracted COVID-19:

  • Severe anemia (from chronic severe nose and/or gastrointestinal bleeding)
  • Heart failure (from severe liver VMs)
  • Chronic liver dysfunction (from severe liver VMs)
  • Low oxygen levels (from untreated lung AVMs or diffuse lung AVMs)
  • Seizure disorder which is not well controlled

Suggested Prevention: Controlling your disease and symptoms as well as possible with your doctor’s advice. The better controlled your chronic symptoms/condition are, the less the risk should be.

Word Key:   AVM=arteriovenous malformation, VM=vascular malformation

*This list does not include information about non-HHT risk factors; people should review those with their physician and follow related advice. View the CDC list of general risk factors here.

 

Update:  March 26, 2020

With many new and existing patients in the HHT Community inquiring about well visits, screenings, scheduled procedures, etc. at HHT Centers of Excellence (COEs) amid COVID-19, we have been in discussion with all twenty-eight HHT COEs to disseminate visit protocols associated with their institutions.  With 90% of our COEs reporting in with their individual non-visit options (Virtual Health), we are compiling a comprehensive list to include details for each institution.  This detailed list will be available on our website as soon as the information is available.  In the meantime, if you are scheduled or need to schedule a visit to one of the HHT COEs, please check their individual websites for current visit information and scheduling of routine procedures. Check back for the comprehensive list with details for each COE.

The U.S. Food & Drug Administration (FDA) advises consumers to beware of fraudulent COVID-19 tests, vaccines and treatments. The FDA is particularly concerned that deceptive products may cause Americans to delay or stop appropriate medical treatment, leading to serious and life-threatening harm. It’s likely that the products do not do what they claim, and the ingredients in them could cause adverse effects and could interact with, and potentially interfere with, essential medications. There are no FDA-approved products to prevent COVID-19.

Epistaxis (Nosebleeds): Almost 95% of the patients with HHT present with nosebleeds although of different magnitudes between them. As they are spontaneous, the manipulation of the nose is a frequent event and often without previous hygienic precautions, due to the suddenness of the event or frequency of the situation. Manipulation of the airway (nose, mouth) without prior hygiene maybe the entry of the COVID-19. The surprising appearance of a nosebleed can lead to manipulation of the nose, face, etc. without first having been cleaned, and therefore, Epistaxis (nosebleeds) may represent a risk condition for entry or dissemination of the COVID-19. For this reason we recommend first to properly sanitize your hands despite the fact that it represents a drop of blood for a few more seconds and then to get the necessary instruments to vigorously compress the nose and clean yourself.

Always remain calm in these situations, be supportive and socially responsible.

Joint Statement – Hematology:
Raj Kasthuri MD – Director, University of North Carolina, Chapel Hill HHT Center of Excellence
Hanny Al-Samkari MD – Associate Director, Massachusetts General Hospital  HHT Center of Excellence

The COVID-19 outbreak has been declared a pandemic by the WHO. Healthcare institutions across the country are preparing for the impact this will have on their patients, staff and resources in the coming weeks to months. Encounters that occur in the clinical setting confer the risk for exposure to individuals affected by the corona virus. All of this is likely to also affect the HHT community.

An HHT diagnosis in and of itself does not increase the risk of acquiring the Covid-19 infection, although other coexisting medical conditions may impact an individual’s risk independent of HHT.

Iron deficiency: anemia is not considered an immune compromised state. A number of people with HHT have iron deficiency anemia and receive frequent iron infusions. Some may also require periodic blood transfusions for severe anemia. We would like to share some thoughts and recommendations with this in mind:

  • Blood transfusions for people with severe anemia should not be postponed as they can be life-saving interventions in the setting of recurrent/ongoing bleeding.
  • All people with HHT who receive regular iron infusions should proactively communicate with their hematologist/oncologist (or other prescribing physician) to discuss the plan for monitoring of blood counts and for iron infusions scheduled for the next 1-2 months.
  • Clinic, lab or infusion visits carry with them the risk of exposure to individuals affected by the virus and the risk/benefit of all visits should be discussed with the provider.
  • Iron infusions in people with HHT are not an optional therapy but an essential component of their HHT care.
  • Withholding iron infusions could result in adverse outcomes such as worsening anemia and related symptoms, need for blood transfusions, and/or hospitalizations.  Therefore, iron infusions should not be delayed or otherwise postponed unless absolutely necessary.

Please continue to follow the CDC’s guidelines and recommendations on hygiene and how best to safeguard yourselves against the infection.

 

Update:  March 12, 2020

We are regularly monitoring updates from our HHT Center of Excellence physicians, the Centers for Disease Control and Prevention (“CDC”), and the World Health Organization (“WHO”).

On Jan. 20, the World Health Organization declared the COVID-19 outbreak an international public health emergency. The U.S. Centers for Disease Control and Prevention (CDC) have issued Level 3 and Level 2 warnings to avoid or postpone nonessential travel for several countries in Asia, the Middle East and Europe only. No travel advisories currently exist for the United States or Canada.

With some spread of COVID-19 occurring in several communities in the United States, the CDC now recommends older adults and travelers with underlying health issues limit travel to avoid crowded places, which includes all cruise ship travel and non-essential travel such as long plane trips. No travel advisories are currently in place for any region of the U.S., but some employers, including many of our HHT Centers of Excellence, in response to current conditions and especially in areas affected by community spread, have begun to issue their own travel guidance or restrictions.

The CDC posted recommendations for people at risk for serious illness from COVID-19, including those over the age of 60 and those with certain health conditions such as chronic heart or lung disease. With those recommendations in mind and given the current situation, Cure HHT continues to refer to our HHT Center of Excellence physicians for their medical advisory as stated below.

Joint Statement – HHT Interventional Radiologists:
Justin McWilliams, MD – Co-Director HHT Center of Excellence UCLA
Scott Trerotola, MD – Director HHT Center of Excellence University of Pennsylvania
Miles Conrad, MD – Director, HHT Center of Excellence UCSF

Since this is a new virus, there is little published evidence about COVID-19. Overall, patients with HHT are not expected to be any more or less susceptible to the COVID-19 virus. The main concern with PAVMs is the loss of the filtering function of the lung, whereby bacteria and blood clots can pass into the arteries and cause well known complications. This is not a concern with a virus. Patients with untreated PAVMs large enough to cause low blood oxygen might be more at risk if infected with COVID-19 because their baseline lung function is not as good as those without PAVMs. This would not apply to those with small asymptomatic or treated PAVMs, for whom there is no reason to believe their ability to fight COVID-19 would be any different because their remaining lung is normal. Anyone with PAVMs requiring hospitalization for COVID-19 should have “bubble” filters on their IV, as recommended by the Cure HHT International Guidelines.

Most importantly, everyone with HHT should follow the CDC’s recommendations. These include:

  • Avoid close contact with people who are sick
  • Stay home when you are sick, except to get medical care
  • Wash your hands often with soap and water for at least 20 seconds
  • Cover your coughs and sneezes with a tissue
  • Avoid non-essential travel to affected areas

Last, but not least, everyone with HHT should continue to follow the CDC’s recommendations regarding travel, hand washing, etc. and stay abreast of changes or additions to these as this situation unfolds.
