Partial muscle biopsy results (and other stuff..)

Kerissa • October 11, 2016

Hey friends,

A lot has happened since I last posted..

For those who were on FB at the end of September, you can just pass over this whole paragraph as I’m basically saying the same thing. lol  On September 22nd, I had an adverse medication reaction that exacerbated my mitochondrial disease….I was taken to the ER by ambulance because I experienced nausea/vomiting (that wasn’t resolving with my home anti-nausea meds), high heart rate/respirations, and weakness.  In the ER, I had to be given oxygen because my saturations kept dropping to 82.  My white blood cell count was high, and other labs were off.  This concerned the doctors, so they did a full infection work-up with urinalysis, blood cultures, and additional labs.  After not being able to empty my bladder for over 10 hours, I had to be cathed, too. *In August after my hip surgery, I had to be cathed then as well.  I’ll never get used to the procedure as it’s so painful!  I know it’s TMI, but I just want to share the unpleasant details sometimes to show how rough mito is.*  I was admitted for 4 nights after this med reaction because I was so weak.  The doctors came to the conclusion that I had stress-induced leukocytosis—the body gets so traumatized that it starts preparing for something bad like an infection, hence the high WBC count.  Thankfully, there was no infection, and my labs soon normalized after numerous liters of IV fluids.  This whole hospital ordeal at the end of September took a lot out of me.

I saw my GI dr. the day after I got discharged.  I had a pulmonary resting energy expenditure test done on Sept. 19th to calculate how much CO2 my body burns, how much protein I need, etc.  But he never received the results!  He’ll either call me or just wait until my next appointment which is at the end of this month.  Based on the results, he’ll adjust my IV nutrition.  When I was in the hospital, the hospitalist recommended I receive 1 liter of IV fluids (vs. my usual 1/2 a liter) a day for one week.  So my GI dr. ordered that.  I only have 2 more days of this regimen!  It’s hard lugging around a very heavy liter of fluids in addition to the IV pump for a total of 6 hours a day. :/

Last week, my eyes stopped oscillating completely….but that only lasted for about 4 days.  It’s now back. I’m grateful for that break, even though it was short!

I had my brain MRI, and it was a clean scan.  I know that’s good news, but I’m still having a throbbing, right-sided headache.  I told my neurologist, and she said there’s often no clear explanation for why chronic headaches get exacerbated.  It could be so many reasons.  I have a follow-up appointment with her at the end of the month to figure out what to do.

I turned 24 this past Friday, and while it was a special birthday (my family is the best!!), I didn’t feel super great—my hip was aching terribly, I had a bad headache, and I didn’t sleep well Thursday and Friday night.  Saturday evening, I threw up a ton—my stomach didn’t have the energy it needed to move the soft food and liquids I had that day out of the stomach and into my small intestine….it was the worst yet.

Last week, I also saw my orthopedic hip surgeon.  Unfortunately, my surgery recovery/physical therapy progress keeps getting set back with each ER visit and hospital stay, so my hip isn’t doing well.  The pain is bad, and she said that’s not normal this far out of surgery.. She thinks there’s scar tissue in the joint.  My physical therapist is also worried about the hip stiffness.  So my surgeon wants me to get a hip steroid injection to calm things down and help the inflammation.  Physical therapy has been very aggressive to work at this, and it continues to be twice a week at OHSU.

Today I saw my palliative care dr.  We discussed all that happened in September and talked about different ways to manage the headaches/pain better.  It’s definitely a trial and error process!

Oh yes, before I keep forgetting to tell, I received my initial muscle biopsy pathology results from OHSU (these aren’t the Baylor tests….still waiting to hear if they got authorized by my insurance…my neurologist had it all taken care of with the medical director of my insurance, but the director forgot to document everything, so my dr. has to start the process all over again!).

OHSU performed basic histology and ultrastructural studies, and sadly, the results are a lot worse than my muscle biopsy histology results done at UCSD back in 2014..  It’s kind of hard to explain, but in 2014, my basic histology was normal…it was only when they ran more tests that they found the mtDNA depletion (a significant one!).  But the histology test done at OHSU in August of this year showed “diffusely pale” tissue which indicates that I hardly have any mitochondria in my muscle. :/  The pathologists noted “paucity of mitochondria.”  Paucity means scarcity.  A lipid depletion was also found, but I don’t know what that means specifically in my case..  Since my histology shows tissue evidence of a mtDNA depletion, that probably means my depletion results (once it’s completed at Baylor!) will be even worse than the 2014 depletion study..  We don’t know if all this means disease progression or what..  I will be seeing my mitochondrial disease specialist in San Diego again this coming January or February to go over everything.

Phew, hope that last paragraph was easy to understand! Sorry for the super long update!!  I no longer journal like I used to (my hand cramps up from the muscle weakness), so I like typing all the details here to remember everything.

Dear friends, Thank you so much for praying for me when I had that bad reaction to the autoimmune medication last month. I’m so incredibly blessed by your love and support. ❤️ I saw rheumatology recently, and instead of trying to prevent actual autoimmune disease from starting, they want to just monitor without any medication therapy. In other words, they want to see if more symptoms like fevers or rashes will appear (besides the joint pain that I already experience).. The medicine I did try (which worsened my mitochondrial symptoms) is actually the “safest” out there, and the other treatments for autoimmune disorders are much harder on the body—the team doesn’t think I’ll tolerate those well.. It’s difficult for them to know if all the bad antibodies that have been found in my blood will cause “actual” disease, and only time will tell.. So the plan is to just monitor and follow up with them in February. I wanted to see if my body could recover from this setback without having my IV fluids switched to a higher dextrose percentage. But by the last week of October (week 3 of this mitochondrial flare), the muscle weakness and increased pain all over was sadly still persisting, so I told my doctor. He sent in a new IV fluids order with the higher dextrose, and I’ve been receiving it for about 2 weeks now. I have definitely noticed an improvement in the muscle weakness which has been a huge blessing from the Lord. It was such a gift to feel well enough to go to a friend’s wedding reception at my church last week. 🥹 My cup was filled because I haven’t been able to see so many church friends in years! Regarding the piece of plaque that traveled to a small artery in my retina, I just had the carotid duplex scan completed last Tuesday to see if there’s any narrowing in the neck arteries. I also have the heart echocardiogram scheduled for tomorrow. My biggest, ongoing struggle has been my sleep. I’ve sadly been in a “catch 22” situation for many months now. I mentioned before that I was started on a new and safer pain medication this year. A rare side effect is insomnia, and it’s simply horrible. Night after night, every single day, I’m not able to fall asleep until after 4-6 AM. 😢 Believe me, I’ve tried every type of trick…from different sleep medications that my sleep specialist has prescribed, to all sorts of sleep supplements, praying, listening to worship music or white noise, stopping caffeine intake, etc. Nothing helps. The thing is, if I didn’t take this “new” pain medication, the pain from Mitochondrial DNA Depletion Syndrome is difficult to manage and it’s like an 8-9 on the pain scale. So then I’m up through the night, in horrible pain, and not able to sleep. But when I do take this medication, the pain is manageable, and it’s much safer to be on... Yet, I can’t sleep well while on it... Catch 22. I don’t know what to do, and it’s hard not to feel alone in this struggle. I’m so thankful to God that my health in other areas has been pretty stable.. In fact, this month (November) marks ONE WHOLE YEAR since I was last admitted to the hospital! Isn’t that soo amazing? Aside from these occasional mitochondrial flares/crashes (which happened in December, May, and October), I’ve been doing incredibly well, now that the neck weakness has resolved. But, this sleep struggle persists day after day.. I would love to be able to attend my church’s morning service in person or do many other activities in the morning. 😞 But I’m super exhausted. So many times, I ask God, “How do I go on and keep doing this every single night?” One thing I’ve learned is that God’s grace is truly sufficient for each day. He is the one who supplies me with the energy and grace to keep enduring. It’s hard, and I don’t know how long this sleep trial will last.. But, as Thanksgiving draws near, I’m reminded that I do have so much to be thankful for. Some of the biggest things: being physically able to help babysit my 4-month old foster nephew, shopping at the grocery store, having hand strength to design new note cards like the ones shown here, no longer experiencing neck weakness, and much more. The verse from Zephaniah I recently hand lettered above has been so encouraging lately. God is right by my side; he is mighty to save and will keep helping me through anything that I face. ❤️

Dear friends, At the beginning of October, I started taking a new medication for the autoimmune disease. I thought I was tolerating it just fine, but after several days passed, I began experiencing nausea, loss of appetite, weakness all over, and increased pain. 🙁 It’s like I’m experiencing another “mito crash.” I found out that this specific lupus medication affects mitochondria. That is, it causes an overproduction of reactive oxygen species (ROS). This, in turn, causes cell damage and oxidative stress. I sure wish the rheumatologists would have known about this before prescribing. But I have to remember that Mitochondrial DNA Depletion Syndrome is rare, and they’re not “mito experts.” Anyways, the last time I felt like this was back in May.. I’m so grateful to God that I haven’t needed to be hospitalized from this, but at the same time, I’m also sad that this happened at all, especially because I had such a nice stretch of stable health. I’d really appreciate your prayers, that this muscle weakness can resolve soon, and that this increased pain all over will get back to my baseline. Every time I have a “mito crash,” it feels like I’m fighting the flu which always sucks. The pain has been hard to bear. And whenever I’m in the thick of it, it’s difficult to remember that this too will eventually pass. 😢 Pray that I will endure and follow Jesus’ example like this passage from Hebrews 12:1-2– “Let us run with endurance the race that is set before us, looking to Jesus, the founder and perfecter of our faith, who for the joy that was set before him endured the cross...” Thank you all so much for praying for me. ❤️
