A 65 years old, female patient with acquired aplastic anemia secondary to frequent exposure to hair dye. While on treatment with anabolic steroids hormone became jaundiced and developed hepatomegaly eight months later. During laparotomy the liver was enlarged, hard, with multiple whitish nodules on its surgace but was otherwise normal. Liver biopsy showed hepatocellular carcinoma, there were not cirrhosis niether hemochromatosis. A review of the related literature was done and discussed on the experimental and clinical evidences that suggested that androgens may play same role on the etiology of liver cancer.

The major cause of chronic post-transfusion hepatitis, the hepatitis C virus (HCV), has been identified. HCV is a single-stranded linear RNA virus with characteristics similar to the flaviviruses. A different agent, the hepatitis E virus, is associated with epidemic (enterically-transmitted) non-A, non-B hepatitis. At present, infection with HCV is recognized by the finding of anti-HCV antibodies, positive in up to 90% of patients with chronic non-A, non-B post-transfusion hepatitis. Antibodies to HCV are detected in 1% of normal volunteer blood donors and in the majority of donors implicated in post-transfusion hepatitis. HCV antibodies are also found in patients with autoimmune liver disease and hepatocellular carcinoma. Moreover, HCV infection may contribute to the pathogenesis of liver disease in alcoholic patients. The role of HCV infection in fulminant non-A, non-B hepatitis and hepatitis-associated aplastic anemia has not been elucidated as yet. Therapy of chronic non-A, non-B hepatitis with recombinant human alpha-interferon has been shown to improve or normalize aminotransferase levels in approximately 50% of patients, most of whom have evidence of HCV infection. However, relapse after cessation of treatment is common. In the future, screening blood for evidence of HCV infection may prevent most cases of non-A, non-B post-transfusion hepatitis.

Between 1974 and July 1987 the diagnosis of severe aplastic anaemia (SAA) was confirmed in 82 patients. Overall actuarial survival was 57% at 7 yr. Four patients recovered while receiving conventional therapy, and four died before treatment with antithymocyte globulin (ATG) or bone marrow transplantation (BMT) could be initiated. Nineteen patients (median age 19.6 yr) were treated with allogeneic BMT (11 as initial therapy, eight after ATG). Incidence of acute and chronic graft versus host disease was high, occurring in 14/16 and 4/11 patients at risk, respectively. Survival of BMT patients (18/19 transfused) was 32% at 7 yr. Of 63 patients treated with ATG, survival was 63% at 7 yr but decreased to 43% at 11 yr. The 2.5 yr survival following ATG was influenced by pretreatment disease severity (defined by percentage reticulocytes, granulocyte and platelet counts), age and--in patients under 45 yr of age--by sex. However, pretreatment disease severity was less in patients aged between 20 and 45 yr and in females. Concomitant androgen therapy, animal source of ATG, interval diagnosis--ATG (which was in general rather short) and aetiology did not influence survival. Thirty-four patients became transfusion independent for up to 26 months after ATG. A gradual increase in granulocyte and platelet counts could be observed over a period of many years, and 26 patients recovered to show a normal haemoglobin level, granulocytes greater than or equal to 1.0 X 10(9)/l and platelets greater than or equal to 100 X 10(9)/l). Late complications (paroxysmal nocturnal haemoglobinuria, myelodysplastic syndrome/acute leukaemia, hepatocellular carcinoma) were observed in nine patients who survived with autologous marrow function. Five died within 12 yr of initial therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

In the presence of aplastic anemia (AA), therapeutic choices should be determined while taking into account not only changes for immediate improvement, but also both the risks for late-occurring complications and the following quality of life. We report here data concerning a long-term clinical survey (5 to 18 years with a median of 12 years) including 156 nongrafted patients receiving androgen therapy; all patients were alive more than 5 years after diagnosis (40% of patients included at time of diagnosis in our multicentric analysis). Between the 5th and the 13th year follow-up, 21 patients died of various causes either related to AA or to its treatment: 12 of infection or hemorrhage secondary to pancytopenia (6 relapses and 6 that had never been improved; 2 with paroxysmal nocturnal hemoglobinuria [PNH]); 5 of leukemia; 1 of a non-Hodgkin's lymphoma; 2 of late side effects following transfusion (1 acquired immunodeficiency syndrome and 1 chronic B hepatitis); and a single case of myocardial infarction (the latter could possibly result of androgen therapy). Thirteen patients in total developed PNH (among which 10 had clinical symptoms including 2 deaths, and 3 exhibited only biologic abnormalities). Few long-term side effects of androgens could be noticed. Adult height was normal in patients treated during childhood and so was young women's fertility. No malignant hepatoma occurred. This survey allows the recording of late spontaneous hematologic improvement (between 5 and 10 years of evolution). This occurred in 50% of patients that had remained cytopenic 5 years after diagnosis. Although bone marrow stem cell concentration remained abnormal after 10 years of evolution. 85% of patients had a normal red blood cell count, 80% a normal polymorphonuclear count, and 66% a normal platelet count. All patients who did not show late complications had an excellent quality of life.

Iron deposits in the human labial minor salivary glands were examined in a series of 195 postmortem subjects. Iron deposits (hemosiderin granules) were found in 7 subjects (3.6%), and the major types of illness in these cases were liver cirrhosis with or without hepatoma, aplastic anemia and acute myelogenous leukemia. Three out of 7 subjects had a history of blood transfusion. Considerable quantities of hemosiderin granules were deposited within the cytoplasm of the acinar and ductal epithelial cells, and hemosiderin-laden cells were scattered in the interstitial connective tissue.

A 33-year-old woman was treated for severe aplastic anemia with norethandrolone over a period of four years, with a cumulative dose of 25 g. In the fifth year of therapy two intrahepatic tumors were detected and were classified as hepatocellular carcinoma and as focal nodular hyperplasia, respectively.

166 aplastic anaemia patients involved in a cooperative study including androgens were followed up for more than 2 years from the beginning of treatment. The mortality rate from aplasia was low (20% of all cases) after 2 years and nil beyond 5 years. The patients who died were either those who failed to improve but survived 2 years or those who late untreated relapse. Five deaths were due to acute leukaemia, but in 3 of these the diagnosis of aplastic anaemia was retrospectively doubtful. Long-term adverse reactions were rare: 2 cases each of benign hepatoma and peliosis; jaundice was frequent, but no cirrhosis was observed. Survivors who had been treated before puberty reached normal weight and height. Six normal pregnancies occurred. Paroxysmal nocturnal haemoglobinuria was noted in 8 patients with uncontrolled disease. After androgen therapy was discontinued 50% of the patients relapsed with equally or less severe symptoms. Relapses were more frequent when androgens were abruptly withdrawn or in cases with incomplete initial improvement. Most relapses responded to androgen treatment. More than 25% of the patients are still androgen-dependent. With or without maintenance androgen therapy, long-term improvement is incomplete in most cases, which suggests residual bone marrow deficiency, as seen in rodents with experimentally induced aplastic anaemia.

We have presented a working hypothesis showing the possible interrelations between proliferative, aproliferative and autoimmune disorders that may follow infection with lymphotropic herpesviruses. Aproliferative disorders in this context may also indicate immune or hematopoietic deficiency. Although this hypothesis can currently be best documented with the lymphotropic viruses (herpesviruses as well as similarly HTLV and HIV), the model may apply as well--with certain variations--to other viral infections such as with hepatitis virus B or C with acute or chronic infectious diseases, post-infectious arthritis, aplastic anemia, and other autoimmune liver diseases, as well as neoplastic diseases (hepatocellular carcinoma, chronic lymphocytic leukemia). The working hypothesis as depicted in Figure 2 permits a preview of which combinations of symptoms may occur in an individual disease independent of its initial classification and what clinical testing should be done respectively, and it also permits certain prognostic considerations. The above-mentioned transitions or combinations of various disease patterns have been repeatedly described in the medical literature (to refer to only a few examples: APL and MPD, HD and MDS, SLE and aplastic anemia, SLE and Kikuchi's disease; 23, 80-83). Finally the hypothesis can ideally serve as the basis for future planning of clinical research.

We report herein the case of a 35-year-old woman with aplastic anemia who developed hepatocellular carcinoma after long-term therapy with oxymetholone. She was treated with 60 mg/day of oxymetholone for 3 years (total dose 64.8 g). Alpha-fetoprotein, hepatitis B surface antigen, and hepatitis C antibody were all negative, but serum titers of carcinoembryonic antigen and carbohydrate antigen were elevated. Lateral segmentectomy of the liver was performed. The histopathological findings were compatible with those of multiple hepatocellular carcinoma without liver cirrhosis. Three years since the operation, the patient is doing well and no signs of tumor recurrence have been detected. According to our review of Japanese cases of hepatocellular carcinoma associated with anabolic steroid therapy, in all instances the tumors developed after long-term administration of anabolic steroids for hematologic diseases. In patients under long-term anabolic steroid therapy, routine screening of the liver by ultrasonography and computed tomography should be performed to detect liver tumors in the early stages.

During the last 14 years, 65 unrelated patients were diagnosed as having constitutional aplastic anemia (CAA). In 52 of 65 patients the diepoxybutane (DEB) test was positive. Comparison of several hematological and clinical parameters in Fanconi anemia (FA) (DEB+) and non-Fanconi anemia (non-FA)(DEB ) patients disclosed no statistically significant differences. The study indicated that in Turkey there were no peculiarities in associated congenital abnormalities in FA and non-FA. The rate of consanguinity was 78% in FA and 46% in non-FA, suggesting that also among the non-FA group recessively inherited disorders are hidden. The mean age at diagnosis in FA was 7.7+/-4.4 (1.8-12) and in non-FA 7.8+/-3.8 (2-15) years. Nine out of 52 FA and five out of 13 non-FA patients died during the follow-up period. Five of the 52 FA patients developed malignancies, three of them had acute myeloblastic leukemia (AML), one a squamous cell carcinoma of the gingiva, and another a hepatocellular carcinoma. Peliosis hepatica occurred in three of the FA and one of the non-FA patients. A total of seven patients stayed in remission without any medication. The remaining 58 patients were given 2-5 mg/kg of oxymetholone and 5 mg prednisolone treatment. Because of sustained remission, oxymetholone therapy was terminated in four of the 45 FA and two of the 13 non-FA patients. Detailed examination of the pedigrees of all of patients indicated the presence of multiple congenital anomalies. In seven of 52 FA and one of 13 non-FA patients there was increased risk for AML and/or other cancers among family members.
