A Snapshot of COVID-19 and Disease-modifying Therapies

Are people with MS more susceptible than the average person to the coronavirus that causes COVID-19? And if COVID-19 attacks them, what’s the likely course of their illness? What about COVID-19 and disease-modifying therapies?

Doctors from around the world are collecting information right now to try to answer these questions. While it’s still early to reach any conclusions, I’ve been monitoring the internet and listening to Zoom meetings from healthcare providers to get a feel for the situation.

Here’s some of what I found:

Renee, who has been treated with Tysabri (natalizumab) for nine years, writes on the MS Connection Blog:

“At 3:30 a.m. on Saturday, I woke up with a splitting headache and fever. I took some medicine and went back to bed. Later that day, still not feeling well, I decided I should reach out to the Cleveland Clinic. By this time, I had a slight cough and terrible throat and ear pain. The doctor turned my case over to the COVID-19 team, who decided to have me tested.”

Renee tested positive, and after isolating for a week, she happily reported that she was doing well, and “fever free for the first time,” with improving symptoms. 

From the BARTS-MS Blog, where “Professor G” has been collecting responses from people in the U.K.:

“I work as [a] Paramedic in London and got the covid19 about 3 weeks ago. Absolutely certain, tested positive. I had fever for 7 days over 38°C [100.4 F]. I feel properly tired, but otherwise ok. Some pseudo MS stuff but ok.”

A Tweet to the #MSCOVID19 hashtag from a PwMS in Manchester, England:

“Update – day 26. After 3 courses of antibiotics, inhalers, all the painkillers, breathing in hot steam and being on near total bedrest, I think I’m finally over the worst. Still a little way to go but feeling a LOT better.”

From a pair 0f Tweets about the effect of COVID-19 on disease-modifying therapies posted to #MSCOVID19 by a neurologist who is tracking the situation in Italy:

“From global observation in Italy: fingo [Gilenya] and DMF [Tecfidera) resumed, Ocre [Ocrevus] pts have delayed but successful immune response, with severe pneumonia resolved in more time but without need of supplementary immunosuppressant treatment.”

“My personal cases: young M on Tys [Tysabri] has been discharged in one week and will retreat with EID [extended interval dosing] as usually in a six-week window; a F on DMF [Tecfidera] treated with Tocilizumab during hospitalization, discontinuing at the moment DMF until full recovery.”

A neurologist from France reported on a weekly video conference held by the group International Women in MS that of 93 MS patients being treated for COVID-19 in the country, no association could be drawn between the use of a disease-modifying therapy and the virus. The same lack of association appeared to be the case in a group of 143 patients in Italy with confirmed or suspected COVID-19.

Better data is needed

All of the neurologists on the Zoom conference cautioned that it’s too early to draw conclusions from this data. In many countries, a person with COVID-19 symptoms isn’t tested unless admitted to a hospital. Many are not admitted, so several people are never tested. Hard data has been limited, which is why several MS groups are now gathering and sharing information about how COVID-19 is affecting people with MS.

This information is being collected under the umbrella of the MS Data Alliance and the MS International Federation. People with MS, with or without confirmed COVID-19, and medical professionals are encouraged to report their experiences. More than half a dozen organizations worldwide are involved, and more are joining the group. (The information gathered may vary depending on the organization gathering it.)

You can also share anecdotal experiences on Twitter using the hashtag #MSCOVID19 and on the BARTS-MS Blog. I’ve shared my information. Will you?

I understand but sure wish someone would find a determination of our meds in relation to the Covid. I’m stuck at home watching old movies, which isn’t too painful.

I've been communicating with my sister in the Bronx, in the very apartment building where most of the folks who are at the epicenter of the horrendous COVID19 outbreak in New York. Her entire family of 4 had COVID19, although no testing was done. My sister was diagnosed with a chest Xray that a tech brought to her apartment.

Her recovery has not been simple. While she does not have underlying conditions, she is susceptible to respiratory infections because she teaches piano to children and adults. she was sick for about two weeks with the COVID!9 symptoms and then began to feel better, only to relapse on several occasions. It's now about 4 wseeks since she first got sick. During that time, her 75 year old husband, 41 year old daughter and toddler grandson all showed symptoms of the virus, and all recovered in the way described in the article.

The virus can express itself in the body in a number of different ways, and recovery is far from straightforward. My sister has been very fortunate in that New York has the infrastructure for a number of telemedicine opportunities and mobile treatment and testing.

Sick as she was, she could neither be tested nor admitted to a hospital. it is desperately important that we keep hospital admissions to a minimum so that we don't further overwhelm our fragile medical infrastructure. There's that word again. What else would you call it?

Stay safe, stay well, STAY HOME.
