Hemochromatosis is a hereditary disease characterized by improper processing by the body of dietary iron which causes iron to accumulate in a number of body tissues, eventually causing organ dysfunction. It is the main iron overload disorder. Hemochromatosis is notorious for having symptoms that are often initially misattributed to other diseases. The defect in hemochromatosis is that you do not stop absorbing from food when you have enough, and you do not put the iron into ferritin when you have too much. The reason that ferritin is high in someone who's had hemochromatosis for 30 or 40 years is not because they have too much iron. The proportions of subjects with elevated ferritin were found to be 37.5% (6/16) for HD and 14.0% (18/129) for HH in male and 0% (0/11) for HD and 3.0% (5/164) for HH in female subjects, respectively. Statistical analysis of all the data revealed no significant difference.

The demonstration of a high serum iron, transferrin-saturation (serum iron/total iron binding capacity) greater than 60% in men and post-menopausal women or 50% in premenopausal women, and an elevated serum ferritin value suggests hereditary hemochromatosis. Serum ferritin levels elevated higher than 200 mcg/L in premenopausal women and 300 mcg/L in men and postmenopausal women indicate primary iron overload due to hemochromatosis, especially when 2000-12-01 · 1..

Hemochromatosis is an inherited disorder, i.e. if you have it, it’s highly likely you have ancestors with it. It’s also said to occur mostly in Caucasians. June Halliday, visiting scientist at Queensland Institute of Medical Research in Australia suggests that approximately 25% of heterozygotes, those who carry the single variation of HFE, may demonstrate elevated transferrin saturation before ferritin levels are increased.

Heterozygous hemochromatosis high ferritin

High levels of ferritin- a protein responsible for storing and transporting iron throughout the body – will alert physicians to the presence of hemochromatosis. Increased levels of ferritin indicate that the iron level in your body is high.

Ferritin is an acute-phase reactant protein that could rise in response to inflammation, infection, or malignancy. Alcohol can also affect your serum ferritin level. Your ferritin is not high, but I would suggest initially checking your fasting serum iron and iron saturation (transferrin saturation). High ferritin, in fact, may have been the initial marker to make your doctor suspect hemochromatosis in the first place.

Statistical analysis of all the data revealed no significant difference. levels of ferritin, the protein that stores iron in the liver; A high ratio of iron to transferrin in the blood may suggest a person has hemochromatosis. A high ferritin level is also typical in people who have hemochromatosis. Doctors may also use blood tests for ferritin levels to see if iron levels are improving with treatment.

When our studies began, the histology of the liver in people heterozygous for hemochromatosis had not been studied, and the relation between hepatic iron stores and serum ferritin concentrations

Increased levels of ferritin indicate that the iron level in your body is high. Transferrin saturation is another diagnostic tool used in hemochromatosis. Hereditary haemochromatosis(or hemochromatosis)is a genetic disordercharacterized by excessive intestinal absorption of dietary iron, resulting in a pathological increase in total body iron stores.

A raised result may be due to iron overload but there are other causes (such as when you are ill) that can give a high result. Therefore, the result is interpreted in combination with transferrin saturation.

Figure 11. Technique of liver biopsy. If the patient has hemochromatosis, I would start a phlebotomy program to keep ferritin levels below 200 ng/mL and transferrin saturation below 40 to 50 percent. The patient could be studied also with T2* MRI for a better definition of the iron overload in the heart and liver.

4 Often, transferrin saturation is the first laboratory abnormality observed; it may be detected in some children and teenagers with the disease. 2,4,6 Individuals who are compound heterozygous for C282Y and S65C may have a small risk for mild hemochromatosis.
