Information Hemochromatosis Basic Information Hemochromatosis is a metabolic disease that results in the excessive accumulation of iron in the body tissues and organs. Eventually, this over-absorption of iron causes body toxicity and can turn into severe body damage. Without treatment, hemochromatosis can lead to organ failure. This condition is also called iron overload disease. It is the most common genetic disorder in the United States. Iron is an essential part of a healthy bodys chemical make-up. A body that is functioning well routinely extracts iron from the diet. The most common sources of iron in the diet are red meat and products that are made from iron-enriched grains. Once the body absorbs iron, it converts the iron into hemoglobin, a molecule in the blood that aids in oxygen transportation. While healthy people typically absorb approximately ten percent of all the iron in the food they eat, a person with hemochromatosis absorbs approximately 20 percent. Because the body cannot release such a large amount of iron, it begins to build up in the body tissues and the organs. The organs that are most affected by this accumulation of iron are the pancreas, heart and liver. As aforementioned, hemochromatosis is a genetic disorder. In fact, it is sometimes called hereditary hemochromatosis. This condition is most common among Caucasians of northern European descent. However, other ethnic groups can also be affected. A little under one percent of all United States Caucasians are at risk of developing this disease. At the same time, men are about five times more likely than women to develop hemochromatosis.

http://www.aafp.org/afp/20020301/853.html

Extractions: Mayo Medical School, Rochester, Minnesota Hereditary hemochromatosis is the most common inherited single-gene disorder in people of northern European descent. It is characterized by increased intestinal absorption of iron, with deposition of the iron in multiple organs. Previously, the classic description was combined diabetes mellitus, cutaneous hyperpigmentation and cirrhosis. Increasingly, however, hereditary hemochromatosis is being diagnosed at an earlier, less symptomatic stage. The diagnosis is based on a combination of clinical, laboratory and pathologic findings, including elevated serum transferrin saturation. Life expectancy is usually normal if phlebotomy is initiated before the development of cirrhosis or diabetes mellitus. Hereditary hemochromatosis is associated with mutations in the HFE gene. Between 60 and 93 percent of patients with the disorder are homozygous for a mutation designated C282Y. The

Kowdley, MD Related Letter If untreated, hemochromatosis can cause serious illness and early death, but the disease is still substantially underdiagnosed. The cornerstone of screening and case detection is the measurement of serum transferrin saturation and the serum ferritin level. Once the diagnosis is suspected, physicians must use serum ferritin levels and hepatic iron stores on liver biopsy specimens to assess patients for the presence of iron overload. Liver biopsy is also used to establish the presence or absence of cirrhosis, which can affect prognosis and management. A DNA-based test for the HFE gene is commercially available, but its place in the diagnosis of hemochromatosis is still being evaluated. Currently, the most useful role for this test is in the detection of hemochromatosis in the family members of patients with a proven case of the disease. It is crucial to diagnose hemochromatosis before hepatic cirrhosis develops because phlebotomy therapy can avert serious chronic disease and can even lead to normal life expectancy. Ann Intern Med.

Khoury, MD, PhD; Joanne Cono, MD, ScM; and R. Gibson Parrish, MD Background: Hemochromatosis, which can lead to serious chronic diseases resulting from iron overload, has an estimated prevalence of 50 to 80 cases per 10 000 persons. However, little population-based information is available on the impact of hemochromatosis on morbidity and mortality. Objective: To evaluate trends over 14 years in deaths and medical conditions associated with hemochromatosis in the United States. Design: We searched Multiple-Cause Mortality Files compiled by the National Center for Health Statistics for the years 1979 to 1992 for all records listing hemochromatosis. We used these data to calculate age-adjusted and age-specific mortality rates, identify medical conditions associated with a known diagnosis of hemochromatosis at death, and calculate proportionate mortality ratios for these medical conditions. Results: The listing of hemochromatosis on death certificates increased 60% from 1979 to 1992. Decedents with hemochromatosis were 23, 13, and 5 times more likely to have liver neoplasms, liver disease, and cardiomyopathy, respectively, than were decedents without hemochromatosis. Conversely, decedents with liver neoplasms, liver disease, and cardiomyopathy were 26, 14, and 5 times more likely, respectively, to have hemochromatosis than were decedents without these conditions. Hemochromatosis was 82 times more likely in persons with the combination of liver neoplasms and diabetes and 43 times more likely in those with the combination of liver disease and diabetes than in those without these conditions.

Extractions: Print this page Hereditary hemochromatosis is a manic disorder in which individuals absorb slightly more iron than normal. This process occurs over decades. However, tissue damage occurs after significant amounts of iron have been absorbed. In most cases, the individual has absorbed approximately 15-20 grams of iron. It is at this amount of absorbed iron in which patients begin to have tissue damage. Also, it is at this amount of absorbed iron that produces significant organ system damage in individuals. Hereditary hemochromatosis is thought to occur with equal frequency in both sexes. However, since regular blood loss through normal menses occurs in females, the preponderance of cases is in males. This approximates 8-1 male to female ratio. Recently, a test has been developed which detects the cellular or genetic abnormalities responsible for many cases of hemochromatosis. The liver is the first site of iron overload in hereditary hemochromatosis. This is based on absorption of iron by the liver. When food is ingested, it is absorbed in the small intestine. This absorption passes into the veins that then form the portal vein. The portal vein then is directed to the liver. The portal vein then divides into small veins that provide the liver cells with nutrients absorbed from the intestine, thus, the liver is the first site in which iron absorption occurs. Typically, liver function tests are elevated in individuals. As iron absorption continues, and the ability of the liver to store iron is exceeded, the heart, pancreas, joints and bones, skin and the immune system become affected.

Extractions: Subscribe now >> Hemochromatosis is a condition in which the body accumulates excess amounts of iron. Serious and sometimes fatal health problems may result from the excess iron that accumulates in the body as a result of this genetic disorder. The excess iron slowly builds to toxic levels in tissues of major organs such as the liver, heart, brain, pancreas, lungs, and synovium (joints). These overburdened organs cease to function properly and eventually become diseased. Hereditary hemochromatosis (HHC) is one of the most common genetic diseases in humans, but it can be undiagnosed or misdiagnosed. Undiagnosed and untreated HHC can develop into diseases such as diabetes, heart trouble, arthritis, cirrhosis of the liver, neurological problems, depression, impotence, infertility, and liver cancer. Iron build up in those with HHC is slow, usually taking years to build to destructive levels. HHC/Iron overload generally manifests in a male's early thirties and is diagnosed in a male's mid to late fifties. For this reason HHC has acquired the mistaken identity of an older male's disease. HHC can be present in females, adolescents and possibly in children.

Hereditary hemochromatosis is one of the most common genetic diseases in humans, but many people have never heard of it. In the United States, as many as one million people have evidence of the disorder, and up to one in every ten people may carry the gene for it. In people who have hemochromatosis, the body accumulates excess amounts of iron. This can result in serious and sometimes fatal health problems. Some diseases associated with hemochromatosis are arthritis, cirrhosis of the liver, diabetes, heart failure and liver cancer. Signs and Symptoms Early symptoms of hemochromatosis are nonspecific and might include fatigue, heart palpitations, joint pain, non-specific stomach pain, impotence and loss of menstrual periods. Even without other symptoms, people with hemochromatosis may have abnormal liver function test results. Symptoms which reflect the tissue and organ damage that result from the disease usually appear in middle age, although some people may develop problems earlier. Later disease symptoms include gray or bronze coloration to the skin, liver cirrhosis, liver cancer, diabetes, hypopituitarism, decreased pituitary or gonadal function, heart disease or heart failure, joint disease, chronic abdominal pain, severe fatigue and certain infections.

Extractions: Hemochromatosis, also called iron overload disease, is the most common genetic disorder in the US. It is a metabolic disorder that causes increased absorption of iron, which is deposited in the body tissues and organs. The iron accumulates in the body where it may become toxic and cause damage. What causes hemochromatosis? The carrier frequency is estimated at one in 10 to one in 15, which means that one in 200 to one in 400 persons has hemochromatosis. Although hemochromatosis is an autosomal recessive disorder (which usually means men and women are equally affected), this condition is 10 times more common in men than women. The age of onset is also earlier in males than females. The reasons for these differences are thought to be due to iron loss through menses in females. In other words, females do not build up iron as quickly over time. What are the symptoms of hemochromatosis?

Simon concluded that HH demonstrates recessive inheritance. - Feder identifies the hemochromatosis gene and the missense mutations (Cys282Tyr and His63Asp) that cause HH. The hemochromatosis gene was originally HLA-H, but was later changed to HFE.

Extractions: Official Gene Symbol: HFE Alternate Symbol: HLA-H Name of Gene Product: hereditary hemochromatosis protein Locus: 6p21.3 The HFE gene is found in region 21.3 on the short (p) arm of human chromosome 6. Size: The HFE gene's 7 coding regions (exons) are scattered over about 10,000 base pairs of genomic DNA. Exons translated into the HFE protein are interspersed with segments of noncoding DNA (introns). After transcription, introns are spliced out and exons are pieced together to form an mRNA transcript about 2700 bp long. The mRNA is then translated into the 348-amino acid sequence of the hereditary hemochromatosis protein [1,2,3]. Mutations in the HFE gene can result in hereditary hemochromatosis (HH). Protein Function The HFE protein is a transmembrane protein expressed in intestinal and liver cells; it works in conjunction with another small protein called beta-2-microglobulin to regulate iron uptake [4]. Although homologous to other major histocompatibility complex (MHC) class I proteins that present antigens to killer T cells, the HFE protein appears to have no immunological function [5]. The HFE protein is an interesting example of how homology is not always an indicator of protein function.

http://www.liver.ca/english/liverdisease/hemochromatosis.html

Extractions: Hemochromatosis is an inherited disease in which the body absorbs too much iron from the diet. Hemochromatosis is one of the most common genetic diseases in Canada affecting 1 in 327 Canadians. Normally, only enough iron to meet the body's daily requirements is absorbed; the remainder is usually excreted through the bowels. In hemochromatosis, however, iron continues to be absorbed and stored in different organs and tissues long after body needs are met. Hemochromatosis is hereditary. In order to have the disease, a patient must have inherited two defective genes, one from each parent; siblings of an affected individual have a 25 per cent chance of getting this disease. Children are less likely to be affected since the other parent must be a carrier of a hemochromatosis gene.

Extractions: Hemochromatosis is an inherited disorder where there is increase in total iron body stores. This leads to deposition of iron in parenchymal tissues, eventually causing functional impairment. Men are affected far more frequently than in women. Arthritic changes are seen in approximately half of the patients. Distribution: Osseous eburnation, joint space narowing, well-defined subchondral cysts, medial beak-like osteophytosis at the metacarpal heads, and osteoporosis are all radiographic findings which are frequently seen in this disease process. Chondrocalcinosis is seen in up to fifty percent of the cases, with a direct correlation noted between the amount of chondrocalcinosis and the degree of arthropathy. Differential Diagnosis: Soft tissues findings in the skin and hand help differentiate psoriatic arthritis from findings in hemochromatosis. There is more involvement of the distal joints in the hands with osteoarthritis. It may be difficult to differentiate hemochromatosis from rheumatoid arthritis based on radiographic findings; however, osteophytosis is rarely seen in RA. Greater propensity for the MCP joints with medial beak-like osteophytosis at the metacarpal heads and more widespread involvement of the carpal bones may help to differentiate hemochromatosis from idiopathic CPPD disease.

http://www.diabetesnet.com/diabetes_types/hemocromatosis.php

Extractions: Cystic Fibrosis by John Walsh, P.A., C.D.E. Hemochromatosis is an inherited disease that causes excessive amounts of iron to accumulate in the body. Although diabetes can be one of many unwanted side effects of the iron overload, the rate of hemochromatosis is no higher in those with diabetes than those without. Diabetes caused by damage to the pancreas occurs after many years of hemochromatosis. In one French study, diabetes was found in 40% of 115 people at the time their hemochromatosis was diagnosed (Acta Clin Belg 1999 Dec; 54(6): pgs. 334-45). This type of secondary diabetes is often referred to as "bronze diabetes" because it is sometimes accompanied by a bronze color of the skin. Screening for hemochromatosis should be done in people with diabetes who also have liver disease. Hemochromatosis is the most common genetic disease in this country with 13% of the population carrying the gene, and one in every 200 people having it. Those at risk often have a family history of the disease, or a history of heart attacks occurring in family members before the age of 50.
