The BioGeek does Covid

It’s been a while since I’ve posted. I know, I know… lazy, lazy, lazy. This time I have a really good excuse.

I caught Covid!

I think that almost everyone who follows my blog knows that I have a type of scleroderma called systemic sclerosis; this is a progressive autoimmune disease that involves damage to blood vessels, lots of inflammation, and then scarring (fibrosis) of organs. In my case, the worst damage is occurring in my GI tract, my heart and my lungs. Because of the lung complications that I have developed I’m pretty high risk for a severe case of Covid-19, so my doctors have encouraged me (strongly) to get updated Covid-19 vaccines as soon as they are available. Because of my interstitial lung disease, I don’t halt my immunosuppressive drug for these boosters anymore.

So, as soon as the new Covid boosters were available I made an appointment, and on October 12th I got my shot. Yay! I was so excited to get it as I usually feel great for a few weeks after the vaccine. Like… my systemic sclerosis symptoms improve, I get more energy, things stop hurting, I can breathe better… you know, better! I know, I know, this doesn’t make any sense, but it is a well observed phenomenon in the systemic sclerosis community. It’s like there is some crazy connection between that vaccine and our autoimmune condition. It does not happen with any other vaccines.

Vaccines always knock me on my butt at first, though, so I wasn’t surprised that I developed muscle/joint pain, chills, fever and fatigue. I headed to bed expecting to feel better in the morning. Nope. I began coughing, got a sore throat, developed a lot of congestion, and GI symptoms arrived. Three days later I began to suspect that maybe this was actually Covid, and that I had unluckily gotten ill on the same day as the booster. I took an at-home Covid test, which was negative.

A little aside: I’m pretty sure you don’t already know that Covid-19 and systemic sclerosis share a lot of similarities. Like, a lot. Damage to the vascular system, the production of a lot of inflammatory cytokines (messenger molecules that travel between cells), and then all those symptoms that can include heart and lung complications that result in fibrosis to both organs. (Covid is a fast-moving firestorm, and systemic sclerosis is more like the relentless slow burn version.) The pneumonia that develops in Covid-19 patients looks so much like the inflammatory lung disease in systemic sclerosis (SSc-ILD), it can be hard to sort out which disease is in play when systemic sclerosis patients like me first arrive in the ER. Okay, things never go well in the ER anyway, so I tend to avoid them. Zebra, right? I decided that I was just in a bad flare and suffered on instead of going to the ER.

Two days later, I retested for Covid. Still negative. Still too sick to consider driving anywhere, too sick to sit up and knit, but not sick enough to call 911. I was kind of stuck in limbo. Maybe some level of hell. Covid hell. Anyway, that booster shot had definitely failed me this time!! I spent my days coughing, sleeping and sadly gazing at my new sock yarn propped up on my bookshelf. I kept taking my immunosuppressive drugs and suffered on.

After a week of this nonsense, I had improved enough to consider going to a Kaiser Urgent Care to see if they could sort me out. Oh. The doctor there was of the opinion that I had Covid after all, but now it was too late for anti-virals or an infusion of antibodies. I got a chest x-ray, some nice antibiotics, a new drug for my cough, and headed back home to the cats and my unknitted yarn.

Tonight, 16 days later, I’m better. I can sit up and knit at last. Through all of this my oxygen levels never dropped, and while I was sick, I didn’t develop any really serious complications.

So, what have I learned about systemic sclerosis, the drug that I take to control it, and Covid-19? I mean, this is a total BioGeek moment! My mind full of dancing antibodies, failed Covid tests, and mycophenolate pills, I took to the internet for answers. There are some take home lessons that I’ve decided are so interesting that I’m passing them on.

1. The similarities between systemic sclerosis and Covid-19 are so significant that the two diseases provide understandings that can help in the treatment of both.
2. The immunosuppressive drug that I take (mycophenolate) to control my immune system’s attack on my lungs can prevent me from producing an antibody response to the vaccine. Okay, I knew that, but I was too sick to think through the implications… because that means…
3. Immunosuppressive drugs can lead to false negative at-home Covid tests. Those tests are for Covid-19 antibodies; if you can’t make antibodies, then you may have Covid but test negative. Oops. (Correction! My cousin has set me straight… the home tests are detecting viral proteins (antigens), so that theory is blown out of the water! Double oops! The doctor told me the mycophenolate was the cause of the false positive tests, and he was pretty emphatic that I should stay on it. Now I’m wondering if the false positive tests were because mycophenolate has anti-viral properties, as some sources cited in the Lancet paper below have reported.) (Don’t you just love science?!!! )
4. The same immunosuppressive drug (mycophenolate) can be an effective treatment for Covid patients reducing their risk of severe outcomes.
5. Staying on the drug was a good decision on my part. I got lucky! Because I am on this drug, however, it can take longer for Covid to clear my system. It has been 16 days, and it looks like I need to isolate for a few more days.
6. I never, ever thought that the treatment for my SSc-ILD would help protect me from the severe Covid complications that the same condition places me at high risk for. I’m so grateful that we didn’t go the chemotherapy route last year.

Isn’t all that interesting?
