Morning/Gooday/Good Evening (?)...
To all my MPN cousins, wherever you might be located…
Recently, I underwent my second BMB, in preparation for the consideration of undergoing an Allogenic Stem Cell Transplant (ASCT), as in February 2018 I learned that I also have the ASXL1 mutation as well as my CALR Type2. Upon learning I was ASXL1 positive, naturally, I grew concerned that my condition had commenced to progress… and I needed to become better prepared for what we know is the only curative option for MF sufferers…
However, (and please excuse the long-winded story to follow), when first diagnosed in May 2016, my BMB showed that I had scarring to the bone marrow of a Grade2 level… there is only 1 grade above that level (3), so it was considered as a serious state of play I guess…
That news turned out to be overwhelming for me, as my MPN discovery was completely by accident/surprise. For finally after much angst, I had been accepted for an overseas posting to S.E. Asia working in International Aid/Development, (a late career change), after more than five years of study… overcoming all the obstacles to become accepted for that position, I was just so thrilled and happy to have been accepted & be going.
However, two days before I was due to leave, the results of my mandatory medical examination became known, and everything changed…
My symptom burden at that time, was really just emerging (and I believe because the onset was a somewhat gradual affair – in my case - I tended not to really notice it, all at once).
A year earlier, I suffered from a TIA (minor brain stroke), (possibly due to high platelets), and after so many years of study… my midriff had also blown out a tad, and I now weighed in at almost 125kg, & my exercise regime was something I read about, and saw others undertaking ... ☹
Upon reflection, I recall that I was suddenly really struggling to complete my assignments on time, and felt under great pressure to perform, and that was very unusual for me, as I thrive on learning anything new. Once accepted for my o/s posting, I remember deciding to let my studies lapse, as I had completed 1.5 degrees at that stage…
In any event, I was so looking forward to my posting, and was already in 11th hour communications with my hosts on a remote Philippine island (Negros Occidental / Oriental), an island divided by its historical ideology.
At that juncture, I was fighting heavy fatigue and nausea, and telling myself that recent events in my own family were the cause with the passing of my father, and my studies playing their part etc…
However, I know now it was my MPN raising its ugly head to new previously un-alerted echelons.
After many months of fighting off the onset of depression, experimenting with a host of different drugs, and struggling poorly with doctors who knew so little…
...I made the conscious effort to know my enemy (MPN), and I actively commenced studying all things MPN. My university still provides me with online access to almost all medical journals, and since most of the medical profession knew so little about my condition, I became most determined to educate myself…
By the time I was to become aware of the potential adversity associated with having the ASXL1 mutation, I had already commenced making myself as healthy as I could via exercise and diet. It seemed a reasonable assumption to me that if one was to survive an ASCT, one needs to be as strong, and spritely as possible … for someone of my vintage (59).
In December 2016, Ruxolitinib dosing commenced at 20mg bd, and since that time, it has gone both up and down on a number of occasions to try to deal with my rather stubborn high platelet counts of circa 750-1M, (apparently higher platelets are more common with the Type2 CALR mutations).
At roughly the same time, I also started trying to improve my health via exercise and diet. Seriously tried the “ketogenic low carb” diet, and achieved some instant success, however, I was at first aware that this action would increase my fatigue levels dramatically, and mental fuge.
It makes complete sense if one contemplates the equation, less energy intake equals less energy. Simple really…
Admittedly, in the very beginning (my exercise regime start), also December 2016, I was really struggling to complete short walks. My fatigue and nausea were so extreme but I continued as best I could – poorly at first.
However, I did eventually become ever so slightly better, and bought an old mountain bike and began struggling to ride 3-5km 2x3 pw. It was so hard, the bike and I was so heavy but I kept at it…
As we all know, MPNs are a condition that affect the blood right? So how could I improve my blood composition? Better minerals/vitamins, and less junk foods… No more wine with my evening meals. However, someone with anemia is low in oxygen in the circulatory system. That’s what started me thinking about what might be the driving force behind my condition… And I began to learn a little about “Metabolic pathways”. Since becoming one of the people with an MPN, no doubt we have also started hearing about where in our systems that these adverse mutations are being acquired
– JAK Stat Pathways ring any bells for anyone?
The JAK/STAT signalling pathway is a promising therapeutic target for the treatment of obesity, metabolic syndrome, and diabetes (Dodington et al, 2018)
Obesity, a worldwide epidemic, is a major risk factor for the development of metabolic syndrome (MetS) including diabetes and associated health complications. Recent studies indicate that chronic low-grade inflammation (CLGI) plays a key role in metabolic deterioration in the obese population (Mishra et al 2015).
Although cancer has historically been viewed as a disorder of proliferation, recent evidence has suggested that it should also be considered a metabolic disease. Growing tumors rewire their metabolic programs to meet and even exceed the bio-energetic and biosynthetic demands of continuous cell growth (Coller 2014)
Cells that cannot generate enough energy due to lack of oxygen, sugars or proteins, common to many cancers, use altered metabolic pathways to ensure their survival. Unfortunately these cancer cells' success comes at the expense of the host patient (Medical Net–news, 2018)
Hence, anything that helps that condition should prove most beneficial – exercise had to become my new mantra! Learning how to breathe again in concert with consistent exercise (and diet), may have saved me, or at the very least increased my longevity…
In any event, back to my good news… as of my last BMB, my bone marrow scarring is now considered to be only Grade 1, as opposed to 2 that it was previously…
… and just to reiterate, I am not suggesting that I have been cured of course, as I haven’t.
However, my fibrotic condition has witnessed a significant improvement, and it appears logical to me, (even if not to anyone else), that much of this has eventuated via my concerted efforts of both diet and exercise over these past 18mths or so since my original diagnosis…
Naturally, my Hematologist is upset with me because I believe my ‘exercise & dietary regime’ has more to do with my improvement than all the medications put together. Ruxolitinib, is an immune suppressant, and most likely is also a contributing factor to my anemia. Therefore, hard to understand how it is really helping me at all… (although it has definitely alleviated some of my more chronic symptoms). Interestingly as well, anemia itself is a lack of oxygen in the blood…
Anemia is a condition that develops when your blood lacks enough healthy red blood cells or haemoglobin. Haemoglobin is a main part of red blood cells and binds oxygen. If you have too few or abnormal red blood cells (which can be initiated by immunosuppressive treatment), or your haemoglobin is abnormal or low, the cells in your body will not get enough oxygen (causing breathlessness to one extreme or the other). (Wikipaedia)
However, I am no Einstein (not by any stretch of my self-proclaimed delusions of grandeur) therefore, I still have much to learn…
So as a quick update to my possible ASCT; my brother has recently acquiesced, and been tissue typed (TT) to see if he is a match, because the MUDs found thus far are somewhat less in that capacity. My younger sister returns to Oz in September, and then I shall also broach the subject with her, if required.
However, I am now seeing all of these actions as merely preparing the way for when, and if, an ASCT is required, rather than believing that an ASCT is a forgone conclusion at some stage... As well, a donors age can sometimes render one’s stem cells as inadequate…
Therefore, perhaps an ASCT is not the only curative option after all… (?)
Incidentally, while I still suffer extreme fatigue, too many cold sweats and low grade temperatures, and a few other MPN symptoms, last week I cycled almost 180kms in three rides, and I am circa 20kgs lighter these days too…
This journey has only just begun… ☺
Best wishes to one and all…
Steve
