Hi Suelou,
I am somewhat familiar with your condition, and one of our members who has become inactive due to other obligations has previously run a forum on PKD. As you said, the mechanics differ as to what happens to red blood cells, but the outcome is similar. What I have observed with thal intermedias, and your condition would most resemble intermedia, is that as they age, many have had to opt for transfusions to improve the quality of life. With today's chelators, this has become a much more common choice. I would suggest really examining your day to day life. Is the quality of your life greatly impacted by low Hb? If so, transfusions should be considered.
