In order to study iron metabolism disorders in patients with portal hypertension syndrome, to determine clinical significance of hyposiderosis and to work out effective method of its correction, 94 patients with cirrhosis of the liver complicated by portal hypertension were examined. As a result of determination of these disorders of iron metabolism methods for treatment of hypochromal anemia and hyposiderosis have been worked out. Hemotransfusions, administration of iron-containing preparation Ferrum-lec and combination of these methods were used for treatment. It was established that administration of large doses of iron-containing preparation Ferrum-lec substantially contributed to improvement of iron metabolism in patients with cirrhosis of the liver and extrahepatic portal hypertension, to reduction of postoperative complications rate and to upgrading the results of surgical treatment.

Juvenile haemochromatosis is an autosomal, recessive inherited iron metabolism disorder. The rapid deterioration and malignant prognosis differentiate juvenile haemochromatosis from hereditary haemochromatosis. The authors summarize the history of a 25 year old man, who worked in Hungary as a guest worker living in Romania. No significant illness has occurred in his previous history. The abdominal pain was his first symptom and he was treated in different institutions, where cholecystitis, alcoholic hepatic disease, hepatic cirrhosis were considered as a cause of his symptoms. Some weeks later atrial tachycardia, and congestive heart failure were observed and he was sent to our Cardiology Department. The echocardiography revealed diffuse hypokinesis, serious systolic dysfunction (ejection fraction: 21%), grade II mitral and tricuspid insufficiency with pulmonary hypertension. Considering the rapid deterioration of his cardiac function, myocarditis was suspected. Myocardial biopsy and coronary arteriography were performed. Coronary arteries were normal. Ventricular fibrillation occurred during coronary arteriography. Myocardial biopsy revealed juvenile haemochromatosis. Special laboratory examinations (transferrin saturation) were made after biopsy, that also confirmed the diagnosis of juvenile haemochromatosis. Cardiac transplantation was planned. Some days after the diagnosis was made the patient died of cardiogenic shock and intractable heart failure. Autopsy revealed hypogonadism and serious haemochromatosis in different parenchymal organs. Juvenile haemochromatosis should be considered in every young patient with congestive heart failure of unknown etiology.

Hereditary hemochromatosis (HH) refers to several inherited disorders of iron metabolism leading to tissue iron overload. Classical HH is associated with mutations in HFE (C282Y homozygotes or C282Y/H63D compound heterozygotes) and is almost exclusively found in populations of northern European descent. Non-HFE associated HH is caused by mutations in other recently identified genes involved in iron metabolism. Hepcidin is an iron regulatory hormone that inhibits ferroportin-mediated iron export from enterocytes and macrophages. Defective hepcidin gene expression or function may underlie most forms of HH. Target organs and tissues affected by HH include the liver, heart, pancreas, joints, and skin, with cirrhosis and diabetes mellitus representing late signs of disease in patients with markedly elevated liver iron concentration. Compound heterozygotes have milder disease than C282Y homozygotes and clinical signs of HH in these patients are usually associated with other factors such as alcoholism and the dysmetabolic syndrome. The most frequent causes of death in HH are liver cancer, cirrhosis, cardiomyopathy, and diabetes, but patients who undergo successful iron depletion before the development of cirrhosis or diabetes can have normal survival. Classical HH is characterized by incomplete penetrance and variable expressivity, and women are less affected than men by iron overload and iron overload-related disease. The diagnosis of HH is established by genetic testing in patients with elevated transferrin saturation values. Patients with an established diagnosis of HH and iron overload should be treated with phlebotomy to achieve body iron depletion followed by maintenance phlebotomy. Population screening for HH is controversial principally because of incomplete penetrance, but screening of selected, high risk populations and first-degree relatives of affected probands may be cost effective.

Recently, we have encountered the rare representation of this disease of the oral cavity associated with generalized burning sensation of the tongue. The diagnosis was established accidently, from the lab investigations, otherwise the patient was healthy and free from classical signs and symptoms of the disease. The patient was adequately treated by phlebotomy. To conclude, all patients with a chief complaint of burning sensation of the oral cavity and tongue should be adequately screened for hereditary hemochromatosis to prevent the associated mortality and morbidity with the hemochromatosis.
