How odd. Why doesn’t your hematologist just cooperate with an MPN specialist. This is a possibility. I had some brain fog before I started HU and after for awhile. I would say it took about 6 months for my blood counts to stabilize and my symptoms to lessen. My memory is not as sharp as it used to be, but I am 71 and I accept that aging may play a role

@eloise999 I should clarify-I did not stop HU. I have been on it for a little over a year.

I was diagnosed in June 2022 with ET JAK2. I have been on different doses of Hydroxyurea since that time. Just search ET JAK2 on this website and you will come up with a lot of people with this condition.
Best wishes, Eileen

@eileen11108 Hi Eileen I was diagnosed with ET Jak2 after I suffered an small stroke called Tia I am also taking hyroxeryea 1000 mg daily, I hope you are doing well I feel the same as always some fatigue but so far so good

I was just diagnosed with ET JAK2 this past March. Taking Hydroxyurea 500 mg twice daily and baby aspirin. My platelet count is slowly coming down from a high of 1027 in February to 684 in early May. I had a bad reaction when I had an Zoledronic Acid infusion for osteoporosis 4 days after starting Hydroxyurea - severe headache, vomiting and diarrhea. The body said too much new stuff at one time.

Good work, bringing your platelet count down in just three months!

But I'm really sorry the osteoporosis infusion knocked you for a loop!

@birgitr I was very grateful she squeezed me in as she is booked out for the next 6 weeks. It is definitely a relief. You kinda motivated me to keep looking for someone and then I was encouraged by your result, so thank you 🙏

@birgitr I had my MPN Specialist appointment today. Lots to tell you.
I was with her for 1.5 hrs. She was excellent. Very knowledgable and informative, so different to my current haematologist. I am going to switch to her care as I don't believe I've been properly managed.
I need to get a few more tests done. I had asked my haemo why I didn't need a BMB and he said because the blood test clearly showed ET Jak2 so no need. I have read many examples of people being misdiagnosed. The specialist advised that the BMB will confirm the subclassification, provide a good baseline for the future and show if there is bone marrow scarring. I will book in for one with sedation.
I also need an NGS blood panel which tests a bunch of other genes which could add to your diagnosis and change your prognosis. A bit scary for sure but as well as ensuring you're being treated for the correct disease, I believe it's better to know what you're dealing with either way.
I am also getting an ultrasound check on my spleen.
My risk for thrombosis is something I have always questioned with my haemo. As he had a number of around 1000 platelets before I started treatment, (my result in April was down a bit, 884), I always wondered if waiting this long was ok given my age and heart risk factors. My haemo maintained that the 100mg asprin rendered half my platelets helpless so my sticky platelets were basically halved but I always wondered how they can be sure of that when mine hadn't been tested.
So there is something called the IPSET thrombosis scoring system which she used today. Based on all my risk factors, I was classified as high risk for thrombosis which equated to 1 in 30 at risk of having a thrombosis episode. As I am high risk she recommended I take asprin twice a day, (am currently on 1 a day), asap to manage the platelets and lower my risk. I need to get my blood checked for clotting first to ensure I will be ok to take asprin at this new dose. She wants me to start HU asap, which will be after the bone marrow test. Her plan is to start me on HU first, to lower my platelets as it works faster, then make the transition to Interferon once my risk is lowered as it can take up to 3 months before seeing a reduction.
I feel relief that I now have someone guiding and informing me of what I need to do and finally have a plan of action other than a wait and see approach. It is a bit worrying to know I am high risk now so I am eager to get all the required tests done asap and start managing the disease with my treatment plan.
Hope all is going well with you. How are you going with Interferon? Any side affects? I hope you are still feeling well. Are you seeing any results?

Can you tell me more about the infusion for osteoporosis?

I’m an active 82, walking or hiking 3-4 miles 2-3 times a week. I was diagnosed with Et with Jak2 after about 4 yrs of tracking my platelet counts (high of 566 but usually in the high400’s) and a bone marrow biopsy. I’ve come down into the 300’s on 500 mg. HU once a day snd 81mgs of aspirin it seems to be working without any obvious side effects! I wish you well.

@kat260 thank you so much for your precise description of your appointment with this fabulous specialist. I am pretty relieved after knowing that this expert emphasizes the necessity of acting instantly. And from my understanding, it is exactly what I have hoped for. First of all it is so vital to reduce the platelets and HU is the only medication which is capable to do this. And after the successful process of lowering those dangerous thrombos the next step could start. And obviously, she prefers the more modern path of treatment, namely interferon. Has she already defined if she’s gonna use Pegasys or Besremi? Can’t wait to hear her recommendation. And I guess you are absolutely right to do this nasty biopsy. I guess this is the gold standard although I have to admit, I am happy that I could have avoid the procedure yet .

By the way, you kindly inquired about my ongoing treatment . Until now the side effects are pretty low. I only perceive red marks at the point where injection has been administered. However, my other blood numbers are too low and we closely observe this development, otherwise the danger of severe infections will increase. Tomorrow I am gonna have my next appointment and afterwards I know the exact numbers and how to deal with this issue. Hopefully we will be in touch to share our stories. I wish you a good start with HU, pleas have in mind that sun protection is key🏖️your Birgit
