Q&A: What GIs need to know about COVID-19
What do practicing GIs need to know? What should they tell their patients, particularly those with inflammatory bowel disease who might be immunosuppressed?
Healio Gastroenterology and Liver Disease talked with our Chief Medical Editor, Edward V. Loftus, MD, from Mayo Clinic in Rochester, Minnesota, about COVID-19 and what the GI community needs to do to address the growing panic.
How should GIs be addressing the topic of coronavirus with their patients?
Loftus: Late last week and this past weekend were kind of a tipping point, and I anticipate we’re going to start getting a ton of calls on this. We’re going to need to have clear and consistent messaging for those patients. We have to confer with our colleagues in the near future to make sure were sending the right messages.
Now that the novel coronavirus is here in the United States, we need to move beyond containment to mitigation. For patients with underlying lung or other significant comorbidities, the risk for contracting serious illness is going to be higher than the younger IBD patient without comorbidities on therapy in remission. Their risk is probably lower.
We don’t want people to stop their IBD meds, because exacerbation of Crohn’s or UC is a real risk. The last thing a patient needs right now is to have a flare and end up in a hospital filled with patients with COVID-19. It’s better for that IBD patient to stay on their meds and do all the things that experts are recommending, like washing your hands frequently, avoiding touching your face, and practicing some social distancing. This would include stop shaking hands with people, don’t go places with large crowds, and avoid non-essential travel.
Is there a significant risk for infection among patients receiving TNF inhibitors?
Loftus: We don’t know yet if there’s a differential risk for the different drugs, but if I had to guess, it would be that corticosteroids have the potential for the highest risk of increasing susceptibility. If patients are on steroids, they might want to taper those. The next level of concern would be the conventional immunosuppressants, such as azathioprine or methotrexate. The biologics are probably okay.
If exposure occurs among a patient receiving TNF inhibitors, is there anything that can be done to curtail infection?
Loftus: We don’t have enough data at this time. There’s been speculation that the virus interacts with the angiotensin-converting-enzyme, which can be found in the lungs. Some people think that patients on ACE inhibitors are going to do better than people who aren’t, but it’s purely speculative at this time. We don’t have hard clinical data that show we can do anything with that.
Anything the practicing GI needs to know?
Loftus: People have been bandying about the idea of a global registry, and people are talking about using some kind of database where physicians can enter in data to track IBD patients who develop COVID-19 to see if there are any issues. I am on an email chain of over 50 physicians from multiple countries, and nobody is aware of any IBD patient who has contracted COVID-19. It’s not scientific, but nobody is aware of such a case. Which is kind reassuring, but doesn’t exclude the possibility that it could become an issue.
How do you handle the panic?
Loftus: There are probably a lot of people out there who are anxious about this and blocking up the health system by coming in and demanding to be tested when they basically have a cold. I don’t know how you address that. It’s a fine balance, but I believe if you give people more information, they are able to process the whole situation better.
I suspect that’s what is going to happen. Once this shakes out, I think the mortality rate will ultimately be lower than expected, and it will also be age related. The typical IBD patient — people in their 20s, 30s, or 40s — their risk for mortality is low. The infirm, the elderly and patients with comorbidities are going to have the higher risk.
But what are the unintended consequences? It could mean more sick calls for health staff. We’re going to have to get used to being shorthanded at times. Hopefully we can keep this under control.
