Ok, you are using language not usually used by HH researchers, e.g. ferritin cages, ferritin protein cage, so you are throwing a spanner in the works, which is a good thing. Isn't ferritin the transporter or trafficker?
I do agree that there is something more going on than what is generally published. Despite my left side chest pain which occurred when my ferritin levels went up (the pain occurred before I knew what the levels were so they were not anxiety) and a feeling that my heart was swollen, inflamed, I too undertook a T2*MRI of my heart at my own expense and they say they found no iron deposits at all. This was after I had been deironed for a while.
However, I did get the best advice ever, from this particular cardiologist before I had the T2*MRI, was that even if they saw it, they can't cut it out, can't drain it, etc, just to keep having those venesections.
There is another factor which I had come across via a study of autopsies of people with iron overload. It was found that the heart (and probably other organs) showed scarring from the tearing into and (on venesection or chelation) tearing out of by the iron particles, which although minute, are still hard with sharp edges.
The tv show "House" actually featured it too. In fact they featured HH at least twice when I was watching it, and from then on always included it in their list of possible diagnoses. However, I have not yet seen the tv shows e.g. Dr Oz, and The Doctors, talk about it even when the subject is fatigue and joint pain. Is it a big secret in the US? Do people ever talk about it?
Like I said, I think the damage is done long ago before diagnosis and treatment, and an old locum actually said that to me in the early stages of my treatment. Consequent haemotologists don't agree. They insist that once deironed we don't have any more problems. I have also found that in my experience, that people who have had glandular fever at some time of their life (usually teens), usually don't have a good time with HH.
I have had a peculiar breakthrough though this year. I was fed up with having 2 hr phlebs, with 4 puncture wounds in order to get sufficient blood out of me. My blood being so thick and black it would not flow. Not all the time, but often enough. I could not get any sense out of haemotologist nor gp (must have been the phlebotomists' fault), when I suggested trying aspirin. Went ahead anyway, taking 100 mg aspirin a day.
In less than a week, I felt lighter, walked faster, I wasn't dragging that ship's anchor and chain around with me everywhere, the pain in my muscles and bones lifted. Next venesection, I filled that bag easily with bright red blood. Then I saw my Iron Studies which had been taken a week before the venesection. They were all NORMAL - like I did not have HH at all!
And I keep tabs on them, I have a spreadsheet where I record them. For the first time since being diagnosed (17 years), all my levels were within the low to normal range. Haemotologist: "It sometimes happens!"
No wonder the pain lifted - I was like a vehicle trying to run on black sludgy oil, now my blood is moving. Although I was always told I had good circulation, and my oxy levels when tested were always 99%.
So, it is a mystery. I have seen no documentation on this at all. However, will wait and see what happens next Iron Studies. Not having it till October now, instead of September as I am due to see Haemotologist in October.
As far as having chelation goes, I have not ever followed it up. It appears to be problematic for some people, although that is the path that those with thallasema often have to take.
Will your haemotologist try you on chelation? BTW, did your T2*MRI show evidence of iron loading in your heart?
