This is what I have been wondering about too Little Bluestem. I did some research last week on this and found info on Hepcidin..
First this page describes low iron and low TIBC/transferrin saturation as being part of the clinical picture of "anaemia of chronic disease"
http://en.wikipedia.org/wiki/Total_iron-binding_capacity
Anemia of chronic disease also known as Anemia of *Chronic Inflammation* (which of course is very relevant to us as PWME) describes how the body regulates iron metabolism via a peptide hormone called Hepcidin, in order to protect itself " eg by keeping iron away from bacterial pathogens". Many of us have chronic bacterial infections eg H Pylori, Chlamydia Pneumoniae.

Quote from this page: "Anemia of chronic disease, also referred to as anemia of inflammatory response [1], or ACD, is a form of anemia seen in chronic illness,[2] e.g. from chronic infection, chronic immune activation, or malignancy. New discoveries suggest that the syndrome is likely largely the result of the body's production of hepcidin, a master regulator of human iron metabolism."
Also: "In response to inflammatory cytokines, increasingly IL-6,[3] the liver produces increased amounts of hepcidin. Hepcidin in turn stops ferroportin from releasing iron stores. Inflammatory cytokines also appear to affect other important elements of iron metabolism, including decreasing ferroportin expression, and probably directly blunting erythropoiesis by decreasing the ability of the bone marrow to respond to erythropoietin."
This is interesting to me as my IL-6 is high.
Then I came across this interesting abstract (havent read the full paper) which discusses the relationship between iron absorption/the role of hepcidin, infections, inflammation and nutritional status, inc deficiencies in Vitamin A and Riboflavin!

I keep wondering how Christine's ideas fit into our, as PWME, with our chronic infections and chronic inflammation.
