A history of phlebotomy therapy for hemochromatosis. Crosby WH. Chapman Cancer Center, Joplin, MO Am J Med Sci 1991 Jan The earlier the disease is discovered, the less risk of morbidity and mortality. Screening tests (serum iron, total iron-binding capacity, serum ferritin) are recommended for all blood relatives of index cases of this hereditary disease and for all clinics where complications of hemochromatosis may be treated: liver disorder however mild, diabetes mellitus, heart disease, arthropathies, sterility, impotence, premature menopause, and abnormal pigmentation of the skin.

Beneficial effect of phlebotomy on hepatitis C virus-associated

Clin Rheumatol. 1998
Interestingly, the response to anti-inflammatory and second line drugs was
poor but unexpectedly recurrent phlebotomies was followed by marked
improvement of the symptoms. This observation suggests that iron overload
may have some role in the pathophysiology of HCV associated rheumatic
complications.

Change in the thyroid function by use of deferoxamine in a patient with hemochromatosis complicated by hyperthyroidism. J Med. 1992 We report on a 74-year-old female patient with primary hemochromatosis complicated by hyperthyroidism. The serum ferritin level was reduced throughout a 217 day administration of deferoxamine (1 g/day). At the same time, the thyroid gland was changed from hyper- to hypo- functional proportionally.
Clinical Consequences of New Insights in the Pathophysiology of Disorders of Iron and Heme Metabolism Hematology 2000 The American Society of Hematology The screening strategy could be based on the assessment of serum transferrin saturation in adults aged 18 or more. Genetic testing testing for C282Y would be confined to individuals with transferrin saturation > 45%. This strategy would then avoid the ethical, logistical, and financial problems raised by systematic genetic testing as well as the societal impact of discovering a genetic mutation in asymptomatic persons without a disease. It is, in fact, essential that major changes occur in the attitudes towards unexpressed or slightly expressed HFE homozygosity, especially by insurers and health care administrators, to avoid any adverse genetic discrimination.
Current concepts in rational therapy for haemochromatosis.
Drugs. 1991 Jun . Venesection should be continued
until all excess iron stores are removed as judged by failure of a rise in
haemoglobin concentration on cessation of phlebotomy. Screening of first
degree relatives should commence from a young age (e.g. 10 years).
Deferoxamine therapy in high-ferritin diabetes.
Cutler P. Diabetes 1989 Oct Data show that lowering
elevated ferritin levels correlated well with diabetes control and improved
fasting glucose, triglyceride, and HbA1c in 8 of 9 patients with high
ferritin levels. This study shows there is a need to study iron metabolism
in poorly controlled diabetes and demonstrates the value of DFO in
controlling high-ferritin diabetes.

Desferrioxamine and vitamin E protect against iron and MPTP-induced neurodegeneration in mice. J Neural Transm 1997 Our data suggested that: (1) iron may induce neuronal damage and thus excessive iron in the brain may contribute to the neuronal loss in PD; (2) iron chelators and antioxidants may serve as potential therapeutic agents in retarding the progression of neurodegeneration.

[Article in French] Diabete Metab 1982 Jun Thus, the decreased HbAIc

consequently a decrease of the time available for their glycosylation.
Hemochromatosis:
A Common, Rarely Diagnosed Disease
By Vincent
J. Felitti, MD, FACP Commentary
by David Baer, MD, FACP. Hemochromatosis is the most common,
life-threatening genetic disorder in North America, yet most
physicians have never personally diagnosed a case: all see an unrecognized
case in their offices every two weeks.
Hemochromatosis can now be appropriately defined as the presence of two hemochromatosis alleles with or without organ injury, and with or without the presence of iron overload.

Hemochromatosis: Conemaugh Health System Hemochromatosis is a condition that develops when too much iron builds up in the body. Excess iron is stored in the organs, such as the kidneys, liver, and heart, and in the joint tissues.

Hypogonadism in hemochromatosis: reversal with iron depletion.
Ann Intern Med. 1984 Nov Our findings
indicate that in some men with hereditary hemochromatosis and hypogonadism
of either testicular or central origin, sexual function and sex hormone
concentrations can be restored to normal after iron depletion therapy.
Hypogonadotropic hypogonadism in hemochromatosis: recovery of reproductive function after iron depletion Journal of Clinical Endocrinology & Metabolism, Vol 65, 585-587, 1987 Thus, recovery of reproductive function, documented by hormone measurements, testicular biopsy, and semen analysis, was complete. We conclude that phlebotomy alone may be adequate treatment for hypogonadotropic hypogonadism in men with hemochromatosis.
Idiopathic hemochromatosis: serum ferritin concentrations during therapy by

Clin Chem. 1982 Aug
Therapy involves mobilization and removal of excess stored
iron through weekly or twice-weekly phlebotomies of 500 mL, until the
hemoglobin concentration becomes less than 110 g/L and remains there for
several weeks, or until serum ferritin concentrations indicate that almost
all the stored iron has been removed (ferritin less than 12 micrograms/L).

Iron Overload (Hemosiderosis; Hemochromatosis) The Merck Manual of Diagnosis and Therapy Section 11. Hematology And Oncology Chapter 128. Hemochromatosis is often diagnosed late in the course of disease after significant tissue injury is present because the clinical symptoms are insidious and the extent of organ involvement varies; thus, the full clinical picture evolves slowly

Peripheral blood erythrocyte parameters in hemochromatosis: evidence for increased erythrocyte hemoglobin content. J Lab Clin Med. 2000 Jan Barton JC, Bertoli LF, Rothenberg BE. Southern Iron Disorders Center, We conclude that increased values of mean hemoglobin, hematocrit, MCV, MCH, and MCHC in hemochromatosis probands are caused primarily by increased iron uptake and hemoglobin synthesis by immature erythroid cells. Mechanisms of iron uptake by erythrocytes that could explain these results are discussed.

Repeated isovolemic large-volume erythrocytapheresis in the treatment of idiopathic hemochromatosis. Z Gastroenterol. 1992 Nov Isovolemic large-volume EA is an effective, fast and safe method to remove excessive stored iron in patients with HC. Compared to phlebotomy, EA can selectively remove RBC, while saving plasma proteins, platelets, and clotting factors. Although, the need for special equipment and trained personnel as well as the relatively high costs are limiting factors of EA so far, it can be of crucial advance in some patients with HC.

1993 Jun In reviewing the other documented cases of reversal it would appear

Life expectancy was reduced in patients who presented with cirrhosis or
diabetes compared to patients who presented without these complications at
the time of diagnosis. Patients who could be depleted of iron during the
first 18 months of venesection therapy had a markedly better prognosis
compared to those patients who could not be depleted during this time
period.
