JAK2 Mutation - Effects and Questions

Posted by ettap @ettap, Mar 29, 2018

Have JAK2 mutation verified twice; one year apart and from different labs. As I understand, it may cause polycythemia vera, essential thrombocytosis, or leukemia. My hematologist has not provided any real info on this mutation so I've been researching via internet. I knew leukemia is cancer but was disappointed to find out today that the other 2 are blood cancers as well. I have been seeing a hematologist every 3 mos. about this since my 2nd blood clotting event in 09/2016. To date, all my blood factors have been in the normal range. Here are some of my questions: 1. Is it typical to verify this mutation well before it triggers one of these diseases? 2. I know early detection of cancer can be a real plus, but is there any research or experience that supports proactive steps that can be taken to deter the onset of any of these possibilities? 3. With polycythemia vera and essential thrombocytosis, is blood letting the primary treatment? If so, can the blood be donated? 4. Since none of my blood factors have ever been out of the normal range to date, no specific result of the JAK2 mutation has raised its ugly head. Is this normal? I'm not typically a worrier. In fact, I do really well with things like this once I know what I am dealing with. Information becomes my sword which allows me to take worry and nip it in the bud.

@roughanne Hello. Well, we have diverticulitis in common as well as the RLS and the PV. After a colonoscopy years ago, the MD told me not even a polyp but I had diverticulitis. I asked him what to do and he said “Eat more fiber.” Subsequently, I never have had any conversation with any MD about it. I’ve always eaten a lot of fiber, and still try to.
The legs I’ve self diagnosed based on what I’ve read and I believe it is one of the results of taking HU as is the exhaustion.
I have a tendency, at my age more so, to consider my overall well being (you know, being alive and mostly well😂).
Once I got past the fear of the PV diagnosis and realized it could be managed, I felt better.
Aside from my hematologist, the Physiatrists I’ve seen at Mayo, have helped me the most. I had never before heard of this specialty. They specialize in Physical medicine and rehab, treating non-surgical conditions affecting muscles, nerves, bones and joints. In plain language I think they treat the “piece” of medicine an old fashioned GP treated by listening to all your complaints and treating what can’t be fixed with surgery. Maybe find a good one in your area? I think that would be a good place to begin. And, I think PT is part of the answer.
I hope this helps and please stay positive and keep posting.

@christina3444 thanks Christina it’s nice to know we’re not alone in trying to figure this out, I’m definitely interested in the holistic approach where somebody will join the dots and give helpful solutions, you seem to have much more access to a big range of services not so much here in Ireland but in saying that the Mayo clinic is very informative, it’s a good age to have health problems as we have so much access to information on the internet. I too have managed my diverticulitis with plenty of fibre , I use a product called inulin it’s a chicory root fibre and a probiotic and come in a powder form that you sprinkle on cereal or add to fruit juice and the good thing I like about it is that you don’t get bloated on it as I did with fibrogel , I get most of my supplements on IHERB and they deliver very quickly , just another question, I’ve to have a bone marrow biopsy next Thursday 11th and am feeling very anxious about it did you at any stage have one and how did it go?

I have the burning and stinging also in my shin bones from the top of my feet to my knees. I honestly think it’s the PV not the meds. Looking back, I had these symptoms before my diagnosis so I hadn’t begun the hydroxyurea yet. It comes and goes and I try to pretend it’s not there. I too have Diverticulitis! Maybe they should do a study? Three people who just had a conversation with PV is a big coincidence. Good luck to all of us..

@nypara66 hi thanks for that info because like you I had those burning and nerve issues long before I got diagnosed with PV but since taking Hydrea it’s much worse and they’re now saying I have RSL I’m totally confused, maybe I’ve had PV all along, have you found anything helpful for the pains and burning in your legs ? they keep me awake at night and I now dread going to bed knowing it going to start, any advice on what helps would be great

@roughanne Hello! I am lucky to have the resources of Mayo near where I live in Arizona.
And, no, I have not had a bone marrow biopsy. At my first visit with the hematologist I have now, she told me that if the HU and phlebotomy didn’t keep things under control that would be the next step.
I expect one of these days it will be advised.
I completely understand your being anxious about it. I know I would be. What we haven’t experienced is usually all the more frightening. But, I’m 77 and I’ve learned from experience that almost anything we approach with dread isn’t nearly as bad as we thought it would be. I had a series of epidurals for my back before they were done in the hospital, under anesthesia and with ultrasound! I was in the doctors office sitting on exam table leaning forward into the nurse, tears pouring down my face….i survived that!
If you’re comfortable with your doctor/s then trust them and from what I’ve seen here, ask for drugs! And, my go to is prayer…when I had nightmares as a kid my grandma would have me say the Hail Mary over and over and like any mantra, I would fall asleep. So, if you’re not Catholic, just repeat whatever “mantra” you’ve got.
I’m certain your post will get plenty of reactions from others who have had the procedure.
I will think of you on the 11th and when you can please let us know how it went.

@irishnanny3 Hello. Based on what I have read about PV, it appears to me that there just isn’t a lot of research about it at this point. Until you have a stroke or develop a blood clot and it’s determined you’ve got PV/JAK2, nothing. But, reading what I’ve read in this forum, there seems to be indications that suggest there may be other conditions that are precursors/warnings such as diverticulitis. Or, not!
I had terrible pain in my knee the day before I was to visit my GP for a regular blood test for thyroid. That turned out to be gout! But, for that coincidence I probably would have just taken a pain med and used Aspercreme.
I’m glad you’re doing well! Last time I had blood drawn my hematocrit (that’s my indicator) was as good as it’s been in 3 years!
I only wish they could tell me why!

Very happy that your bloodwork was good
Mine has been too!
After I was diagnosed I did lots of research and learned that tinnitus is one indication, fingers that feel cold and look bluish( had both of those) are another
Stuff like that is so random, don’t know how you’d guess
And who ever heard of PV??
Happy holidays and stay well

@christina3444 thanks Christina it’s great to connect with others with similar problems, and now I have another-problem I would like help with ,I’ve now been told that the problems with my legs ,burning tingling and sensations at night which I’ve had for the last three years is restless legs syndrome and now don’t know where it fits in with the PV diagnosis and what if any medications I can take to help as I’m worn out with lack of sleep 😴 between having diverticulitis (managed) kidney stones, very large gallstone (on surgical list to have removed)NAFL arthritis in my back , the PV and now restless legs I’d love to know if anyone has multiple health problems like mine and how they manage and instead of attending different specialists (costing me a fortune) if there is any one type of doctor who could deal with everything and put a plan in place , all answers gratefully received

My GP gave me a low dose of Gabapentin three months ago. I had major leg cramps for years waking me up hourly! I've only had cramps 3 nights!! So far so good. I tried everything.

@christina3444 hi nice to hear from you again it’s appears we have a lot more in common apart from our medical issues, I too am 77yrs having just celebrated my birthday in November and also I have a great devotion to our Blessed Lady and pray nightly to her and I’m sure she has and will always keep me safe, I also do a weekly novena on a Tuesday to saint Martha (our Lady’s sister) and also Saint Anne her mother and my patron saint , you could say I’m keeping it in the family!!!!!! and like you you need to believe in something otherwise you can’t make sense of anything, I was on to my consultation this morning and told him about my side effects and has told me to come off Hydrea until they get the results from the biopsy which he is doing on Thursday and he will discuss other treatment options with me then so all good at the moment and just keeping positive, will be in touch when it’s all done 🙏

@diana56789 thanks for that info but unfortunately for me gabapentin didn’t work for me nor did duloxatine another drug that works in a similar way but I’m hoping that they will come up with something else that works as it’s very waring not getting a good nights sleep 😴 but I’m glad for you that you’ve found something that helps

@roughanne Well, it sounds like you are taking charge of this! And good for you!
Yes, it sounds like we have a lot in common. Good as well as bad. You sound much more devoted than me, so keep me and all us “mature” women in your prayers please.
This was not what I expected to deal with when I retired but then this is just another test and I know I will get through it just as I always have.
I read all the other posts and consider that PV is certainly not the worst thing I could have by a long shot!
Please keep us all posted on your progress and feel free to vent!
Happy Christmas and the best of New Years!

@roughanne I had a biopsy in the Interventional Radiology facility on October 14 using a CT scan to fine tune location and under sedation. They gave me a sedative and a bit of fentanyl to help block pain. I felt nothing until the end when they "vacuumed" out the last of the blood, but it was momentary and not terrible. I remember saying "Ouch" and that was it. I had to really fight with my Oncologist for the sedation because she has bone marrow rooms within the cancer center but they don't do sedation there.

@JustinMcClanahan hi I too have been recently diagnosed with PV and JAK2 mutation I’ve been on hydrea 500 for the last 4 weeks and and am suffering from neuropathy especially at night which is keeping me awake also awful fatigue and I have a couple of questions I hope can be answered firstly I have bad around my back and was taking Vimovo and no not sure what painkillers if any I can take now? Also with Christmas coming up and all the festivities is it ok to have a glass of wine as it says on the info with hydrea not to drink alcohol also if any has neuropathy what have they found helps as I’m new to this I’d be grateful for any helpful suggestions to manage symptoms

@roughanne I too am starting to have neuropathy in my feet and it happens all day long. I have been on HU for 33 years and this has just started now that I am starting to convert to PV, otherwise have ET JAK2 mutation. Is the neuropathy a symptom of the PV? or the HU? I have a glass of wine about once a week, just to feel like I am enjoying life, but otherwise I know the alcohol is not good while taking HU. Recently just found out that I have LOW IRON. now diagnosed with Iron Deficiency Anemia, but my HCT and Red count are normal. (my PCP ordered it for me since my Hematologist does not do tests other than CBC. I started on 324mg of Ferrous Gluconate on M, W, F. anyone else have low iron? itneverstops. Leene
