The Scleroderma Chronicles: Song of the Cell, Dance of the Cytokines

I’m reading a really wonderful book right now that is really speaking to me on so many levels.

This man is a BioGeek of the first order! He interweaves his experiences, patients, memories, and the history of cells together in a way that makes me green with envy. He unpacks the history of our understanding of cells by bringing those scientists to life in a way that makes me care about them; if only I could write that well. He is the teacher that I wish I had been as he reveals to us how cells work together to create complex human systems, and then ties all of that to the treatment of disease. I’m still in the first parts of the book, but I have already filled my kindle with highlights and notes.

This book was published at the exact right moment when I needed it. I have totally gone down the rabbit hole at PubMed over the last two weeks as I have read paper after paper while chasing down the major players in my chronic conditions (why am I sick, and what exactly are these new meds doing…) and how they link to inflammation. Why would anyone do something like this?

Well, it all comes down to this. I’m on high-risk drugs with some serious side effectss, and I want to make informed decisions about whether I continue taking them. I also had a run-in with elderberry juice, and was rescued by green chile; as a BioGeek I was sucked down the curiosity rabbit hole after that whole adventure. What? That doesn’t happen to you? Listen, it has been so bad I haven’t even been knitting!!!

These are the two drugs that I’m trying to understand. In his book Siddhartha Mukherjee argues that our understanding of cells, and how they work, has transformed medicine into the modern miracle that I am currently benefiting from. Drugs that directly interact with the molecular machinery of cells, the signals between them and the biochemical pathways that cells use to function, are the first of the major transformative directions modern medicine is taking in the treatment of so many pathologies such as cancer, diabetes, neurological, and autoimmune diseases such as mine.

Systemic sclerosis is really darn complicated, as it turns out, and the sequence of events that have been happening in my body are so convoluted it’s hard to track them all. It started in the cells lining my blood vessels. As those cells got injured, they sent out signals that activated parts of my immune system. Signals from the immune cells caused other cells to transform and they began to produce scar tissue… scleroderma means “hard skin”, the hallmark of my condition. Whew. Here’s a condensed version of all that if you want to torture yourself and/or fall asleep.

Let’s go back to my meds. Ambrisentan blocks a molecule that is involved in making blood vessels constrict and raises blood pressure when it is active. That molecule, endothelin, is getting turned off by the drug, and there is evidence that this will improve my exercise-induced pulmonary hypertension and will also keep it from progressing; it plays nice with my other pulmonary hypertension drug which shuts down an enzyme pathway involved in blood pressure. Ofev is my new (fairy dust) drug, and it disables some of the essential enzymes in the cells of my lungs that are involved in creating scar tissue. Interstitial lung disease is currently the leading cause of death for systemic sclerosis patients; mine is being treated by side railing the process in the cells that are essential players in the pathology.

Yay! Molecular trickery at the cellular level saves the day! I will be staying on these meds as long as I can.

Dancing to the tune of the song of immune system cells are cytokines, the messenger molecules that travel between immune system cells and other cells that they interact with. The dance is complex, with all the different messengers traveling through the blood to target cells in the body, latching on and causing the cells to take actions. Some cytokines increase inflammation, and other will shut it down. Your immune system can get dialed up or shut down, depending on what the messages are. In my travels through research papers at PubMed I focused first on what cytokines were involved in systemic sclerosis, and then I hunted for papers that had measured the levels of these cytokines when people ate different foods.

Foods that you consume can make a big difference, evidently. Elderberry made me much worse (I cried in two different doctor’s offices), and green chile saved the day. I was done doing google searches for “anti-inflammatory foods” and was going after hard data.

.What did you expect? I’m a BioGeek. OF COURSE I made a spreadsheet with the data!

Tumor Necrosis Factor alpha (TNFα) is a big driver in the whole systemic sclerosis story along with Interferon gamma (IFN-γ). They cause an increase in two more cytokines that promote inflammation, Interleukin-6 (IL-6) and Interleukin-1 beta (IL-1β). All four of these bad boys will make my inflammation worse and (probably… I’m guessing here) encourage my conditions to progress. A lot of these foods/supplements will lower the levels of these cytokines, which explains why I feel better when I eat them. ELDERBERRY increases three of these cytokines which is why I felt like death warmed over while drinking it. Google said it was anti-inflammatory… can you see why I switched to research papers and cytokines? Green chile stew has tomatoes and green chile in it (and some yummy pork and garlic!); no wonder it turned things around. I will try to eat as many of the “good” foods as I can, but I’m going to focus on ones that really shut down TNFα and IL-6. I’m ignoring the IL-10 and CRP info because it wasn’t really as well supported as the others, and I know that my CRP (C-Reactive Protein) levels are normal.

My lunch smoothie: tart cherries, raspberries, banana, spinach, yogurt, chia seed (gag) and cranberry juice. For dinner I’m having a green chile cheesy corn pudding thing that tastes pretty darn good.

Wow. Did you read all of that stuff above? You deserve a prize for perseverance.

Here’s your prize. It’s like a “Where’s Waldo” picture, but this one is Where’s Hannah!

So, there is all is. Inside my systemic sclerosis, pulmonary hypertension, interstitial lung disease self, there are all these dancing cytokines, following the song of cells. Scientists who were captured by all of this and who were entranced by the Song of the Cell have developed the drugs that are treating the two life-threatening complications of systemic sclerosis that have come my way. Inside me, the promise of the song goes on.

Time to get back to my book.

Notes:

  • Okay, I made a whole other spreadsheet with links to all of the research papers that I used to get some understanding about these cytokines, and which were important in my disease. You don’t want to see all of that, right? If you do, say so in a comment and I’ll send some links your way!
  • I became curious about what is happening with Covid patients and the cytokine storm that can cause severe symptoms. Yep. It’s happening because of TNFα, IFN-γ, and IL-6. If you catch Covid, I don’t recommend elderberry.
  • Clinical trials are currently underway to see if an IL-6 inhibitor will be an effective treatment for systemic sclerosis.
  • I’m a lucky, lucky girl. I have a degree in molecular biology, used to work in an immunology lab that focused on IL-1, was involved in a scleroderma research project, and finished up my lab days on a project looking at the impact of capsaicin on rheumatoid arthritis. I can almost understand what I’m reading on PubMed. Almost.

The Scleroderma Chronicles: Unforeseen Circumstances and Unintended Consequences

I guess almost everyone in the world knows by now that the United States Supreme Court issued a ruling last month (June 24th) that overturned the constitutional right for a woman in the United States to seek an abortion at any time during the first two trimesters of pregnancy.

This post isn’t really about abortions, okay. This is about the unbelievable unintended consequences of that decision for women who are dealing with unforeseen circumstances. Women who are dealing with medical conditions that they never saw coming, and that they absolutely did not bring upon themselves.

Like autoimmune disease. Like cancer. Like any one of a number of medical conditions that require serious, high-risk medical interventions by the medical professionals who are treating that woman.

My first inkling that there might be a problem with the Supreme Court ruling that was much larger than what was being reported in the press happened the evening of June 29. A woman in one of my autoimmune online support groups posted that she saw a message from a doctor who had a patient reporting that she couldn’t get her methotrexate prescription renewed. I literally couldn’t sleep that night I was so upset. In the days that followed there were more reports, and this is really happening to some women. They are being denied refilling of their methotrexate prescriptions. This drug is a common one used to treat autoimmune diseases like rheumatoid arthritis, lupus, and scleroderma. It is a chemo drug, it can harm an unborn child, and it can also be used to induce an abortion. Here is an article on Health.com, another at msn Everyday Health, and this one from Time.com.

My morning pills.

There are some serious drugs there in my hand. The green pills, Myfortic, can harm an unborn child by causing birth defects or a miscarriage. I take 6 of those every day. The white capsule, omeprazole, should only be used “only if the benefit outweighs the risk to the fetus”. I have to take two of those each day. That little pink pill towards the upper left is the really big problem in my hand. That drug, ambrisentan, required a rigorous enrollment process with paperwork from my cardiologist and myself along with two interviews by pharmacists. I had to prove that I could not get pregnant to avoid taking a pregnancy test prior to each month’s supply of the drug being shipped to me. Even with all of that, I am screened each month before the next month’s supply is overnight express shipped to me. This drug poses a serious risk to a fetus. In my support groups for pulmonary hypertension there are women who are reporting that they are getting dropped from the programs that allow them to get the drug.

I’m okay because I’m beyond childbearing age. Many other women who are dealing with autoimmune diseases that require drugs such as these are of childbearing age. Why? Because the people in the population who are at the greatest risk of developing an autoimmune disease are women of childbearing age, that’s why. Because of the recent decision about access to abortion these women are also now at possible risk of being denied treatment for their autoimmune disease, or in the worse-case scenario, access to an abortion in consultation with their medical professionals.

I literally couldn’t sleep when I read the first reports of the problems with access to methotrexate in my online forums. This is absolutely unbelievable. This is unbearable. How could this be happening to a population of desperate woman, through no fault of their own, who are in this horrible situation? Right now, methotrexate is being targeted, but there are all these other drugs that are used for so many patients with so many conditions. Women, absolutely, are at risk of receiving inferior health care in the US.

This is awful. Have a rose. Right now, I need a rose. And a hug.

This is hitting me hard this evening because I have been dealing with autoimmune pneumonia since last December. My doctors are trying to get it under control with high dose immunosuppressants, but I am coming off one of them right now and I am struggling with shortness of breath and chest pain once again. I’m back on daytime oxygen and I’m feeling a little low. The lung biopsy was the first engagement with my interstitial lung disease, this current drug strategy the second battle, and the third battle is looming on the horizon. This isn’t a disease; it is a war. I never asked for this, and yet, here I am trapped in this unforeseen circumstance, engaged with an uncurable foe. Without the drugs in my hand above, I would already be gone. Yay, science!!

I think that there is another CT scan in my near future, and then there is a possibility that my doctors will move to the Plan B (see what I did there) that they have already discussed with me. Cyclophosphamide (a chemo drug) and OFEV (an anti-fibrotic drug) are on deck if my doctors decide to escalate my care. Both of these drugs can harm an unborn child. I will get access to these drugs. If I was in my 30s, as many other members of my support groups are, it might be a different story. What about women in other support groups that I don’t belong to who just got diagnosed with cancer or an equally serious disease who also need medical treatment with high-risk drugs such as these? Women of childbearing age. Women who may already have children who they need to think of and care for in their health care journey.

Being diagnosed with an autoimmune disease like the ones that I have (systemic sclerosis and Sjogren’s disease) is a punch to the gut. Being denied access to treatment because of your childbearing status is an unbearable second blow. Becoming pregnant while on one of these drugs would place a woman in an impossible situation. Nothing, NOTHING, about this situation is good. Where is the privacy for these women? Where are the HIPPA protections that they are entitled to? The decisions that these women face are absolutely heartbreaking, morally complicated, and ethically challenging. They deserve privacy as they make them along with their health care providers, religious advisors, and families.

This post isn’t about abortion, not really. This post is about unforeseen circumstances and unintended consequences.

I feel a lot better for having gotten this out.

Peace be with you all.

Take this rose with you as you go.

But if you decide to share this post, write a congressperson, join a march, or take some other action to ensure that women have equal access to health care, that would be great.
