Effect of gradual accumulation of iron, molybdenum and sulfur, slow depletion of zinc and copper, ethanol or fructose ingestion and phlebotomy in gout.
Gout affects mostly males over 40 years old and, occasionally, postmenopausal women. This pattern coincides with the pattern of iron accumulation. On the other hand, menstruating women are seldom afflicted by gout, because the monthly blood loss causes them to accumulate iron to a much lesser degree. Gout involves seven aspects: (1) uric acid overproduction from increased purines in the diet; (2) uric acid overproduction from ATP degradation; (3) uric acid overproduction from increased de novo synthesis of purines; (4) uric acid overproduction from increased DNA breakdown from cell damage; (5) decreased uric acid elimination, caused by molybdenum and sulfur binding to copper in the kidneys; (6) precipitation of sodium urate-iron crystals in the joints due to high ferritin and saturated transferrin and low CuZn-SOD and Cu-thionein in the joint; (7) development of inflammation, triggered by tyrosine bonding to the sodium-urate-iron crystals and being transformed by tyrosine kinase. Alcohol and iron greatly affect most of these aspects. Therefore, phlebotomy is suggested as therapy for gout patients, in order to eliminate the accumulated Fe. Furthermore, yearly blood donation is recommended for males with a family history of gout, so as to prevent Fe accumulation and avoid gout.
