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.

Just saw this and was surprised to see your mention of diverticulitis .. I too, was admitted to the hospital for intravenous treatment for it since they saw infection on CT
Only one time
I have PV with Jak 2
Discovered when I had a
stroke and two DVT’s in 2018. Had just two phlebotomies, the just
Hydroxyurea and Eliquis since. Counts are good
Best wishes to you

@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!

@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 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

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..

@roughanne Yes, that neuropathy is a “b—-h”! I take one Magnesium 400 mg capsule a day and recently changed to taking it in the evening. That seems to help with the foot/leg problems at night.
The exhaustion is probably what I have complained of most but it comes and goes, at least for me. So, I make the most of my bursts of energy and when I get tired I stop and rest. I try not to nap during the day because that affects how well I sleep. But, rest!
And, I too have a bad back. Exercise, damn it😝helps. Get some PT. I have taken Tramadol when I needed it (rarely). I woukd ask your hematologist and your pharmacist about that med (Im unfamiliar with it).
As far as alcohol, I use wine in my cooking but just don’t have much taste for drinking anymore. I do have one Vodka Gimlet for my birthday (old habits die hard) and so far no ill effects. But, I would ask your hematologist.
I’ve been on this journey for about five years. There are worse things!

@carlavan, welcome to Connect. I moved your discussion to the Blood Cancers & Disorders group and combined it with a discussion where other members are talking about JAK2 mutations and essential thrombocytosis. While we wait for other members to jump in, would you mind sharing a bit more about yourself? Have you talked with your hematologist or medical provider about the possible connection between your ear infection and essential thrombocytosis?

Thank all of you for the good info and good wishes. I'll make note of your suggestions, too. I'll also update after my next doctor's appointment near the end of September.

Stay well.

Yes, but I itch random times of the day. It’s really frustrating. I find antihistamines help but don’t stop it all. I haven’t found any creams that work. Like you, searching for an answer.

Hello. I’ve had relatively little itching since I started HU about five years ago. Curiously, my right shoulder blade area is where it happens most often and my hands were giving me problems. The backs of my hands would develop little pinpoints like tiny scabs and they would begin to itch like crazy. And my nails, never good, just started splitting and breaking no matter what I did. Then I tried Naturewell Retinol Cream. It sounds like they are paying me (not) but it is amazing. Sam’s sells it at a great price and it’s a little more on Amazon.
Since I started using it nightly, my hands are completely itch free and my nails have stopped cracking and breaking. Very little of the stuff goes a long way. It feels lovely and I’ve started using it as a body lotion. I had tried a very expensive crème recommended by the MD, the oatmeal lotions and nothing worked until this. Maybe try it and see if it works.

Hi,
Is this discussion still active?

I just found the website yesterday and have been reading threads, but most seem to be old ones. Are there current active ones too?

I was diagnosed with ET in April, JAK2 positive, everything else normal, no symptoms. Other causes ruled out with tests but no bone marrow biopsy done. Platelet count has been steadily rising for a couple of years, now 581. Specialist put me on low-dose aspirin daily and said if count goes over 600k, which it likely soon will, he'll put me on Hydrea. I don't like the idea of that but I don't want to have a stroke or heart attack from a blood clot. He said that's the biggest danger with ET and that I'm high risk for clots. He said most tolerate Hydrea well. He said I'll need to get blood drawn every 3 months but he will alternate with my regular doctor, who always does lab work anyway.

I've always been healthy and this new medical issue is a bit unsettling, but I'm trusting the Lord to get me through it. I know I'm very blessed to not have this issue at a younger age. I have to go back to him in Sept.

I've already found this forum to be helpful and reassuring, but I would like to join an active discussion. Best wishes and thanks to all.

Really glad to hear you were diagnosed before having a stroke or heart attack
I, too, am Jak 2 positive but wasn’t diagnosed until I had a stroke and two dvds while recovering. Initially had two phlebotomies but once I was on Hydroxyurea no longer needed. Been on since 2018 and no side effects (no itching). Know everyone us different
Did have bone marrow biopsy once diagnosed, which showed no damage to bone marrow Wishing you the very best. Keeping informed is great
