Mitochondrial genetics appointment.

Kerissa • June 2, 2017

Hello friends,

My family and I got back from CA on Sunday.  It was a super quick trip, but we were able to spend a lot of time together which was so special.

Our first two evenings there, I suddenly had terrible nausea and severe muscle weakness to the point that I couldn’t lift my arms or even get up to brush my teeth.  All I could do was lay on the hotel bed.  It was even so hard to hold my phone up. I couldn’t help crying because it was scary.  This didn’t happen at all when my parents and I traveled to San Diego in January.  I hate that I’m getting worse and feeling the disease progression. :'(  If I were home, I would have had to go to the ER.  At one point, I thought I’d need to go to the hospital in LA.  We don’t exactly know what caused these episodes—maybe a combination of very low blood sugar (despite being hooked up to my regular tube feeds and IV fluids), exhaustion from not getting enough rest, etc.  So for the rest of the trip, my family mainly pushed me in my chair (instead of me “wheeling” myself) so that I could save energy.  When we went to Universal Studios on Friday and Saturday, I didn’t wake up till the afternoon so that I would have enough strength.

Regarding the appointment, my mitochondrial geneticist spent 3 1/2 hours with me!!  He is amazing and so knowledgeable.  He hasn’t seen a new patient in more than a year because he mainly travels across the US and teaches doctors about gene sequencing and more, but he wanted to see me because I stood out to him! So grateful to be under his care!

In a nutshell, he explained that I have a multi-factorial (polygenic) mitochondrial disease which means it’s not just one gene mutation causing the disease—it’s a combination of gene variants that are contributing to my symptoms.  He believes the CHAT variant I have is modifying the TRAP1 (TNF receptor-associated protein 1) gene.  In his words, TRAP1 is a mitochondrial chaperone that is believed to protect mitochondria from the effects of reactive oxygen species-related damage.  Having CHAT and TRAP1 together is much worse than if I just had one or the other.  He said patients with both are in bad shape.  I have intestinal failure and many other things going on.  He agrees that my mitochondrial disease is progressive.  In his practice, 90% of his patients improve or stabilize with his treatment and 10% don’t…

He’s putting me on high-dose co-factors (antioxidants) and supplements.  He wants my blood CoQ10 level and blood “free and total” carnitine level checked.  Normal blood CoQ10 is under 4, but he wants my level to be way above 4 because he has found that a higher level is much more effective to help.  Once I email him the blood results, he will tell exactly how much of each antioxidant I need to take.

He stated that I shouldn’t go more than 2 hours without eating because fasting makes everything worse.

He also wants a migraine genetic panel done through this certain lab that is a division of Courtagen Life Sciences (he’s the medical director of Courtagen, and I had gene sequencing through them).  There are many genes (including pain genes) on this panel that I haven’t had sequenced before.  And the results will tell him exactly what migraine treatment is good for each variant that is found.

He wrote up a very long report for me and my doctors which is so helpful!  He wanted to see me back in 6 months, but we’ll see him in a year instead because it gets expensive traveling and because I still see my mito dr. in San Diego.

Here are few pictures from the trip. Some of these I already posted on FB, but I know some of you aren’t on, so I wanted to share them here!

My GI dr. told me to find these two famous paintings in the Huntington Library known as Pinkie and the Blue Boy. They face each other from across the room!

The Huntington Library and Botanical Gardens in Pasadena was a highlight of the trip!!

the Gutenberg Bible!!

My family and I had a blast at Universal! It was so much fun, and we didn’t have to wait in line much at all because they let us use the front-of-line access since I’m in a chair!That was a huge blessing!

_______________

Today, I had a follow-up with my PCP.  She is going to order the migraine panel that my mito geneticist wants done.  She is also going to talk to my nephrologist and GI specialist to see about adding D5 (dextrose) to my daily IV Magnesium bags.  Hopefully it helps prevent those weakness episodes (as I had another episode a couple days after we got home) since the body can get energy fast from dextrose infused directly into the bloodstream.  Waiting to hear if my neurologist can order the blood tests.  In 2 weeks, I see my GI specialist again.  And tomorrow, I resume physical therapy..  Thank you for all your caring comments and continued prayers, especially after my previous post!  I love you all!

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. ❤️
