Treatment of inherited bone marrow failure syndromes beyond transplantation

Despite significant progress in transplantation by the addition of alternative hematopoietic stem cell sources, many patients with inherited bone marrow failure syndromes are still not eligible for a transplant. In addition, the availability of sequencing panels has significantly improved diagnosis by identifying cryptic inherited cases. Androgens are the main nontransplant therapy for bone marrow failure in dyskeratosis congenita and Fanconi anemia, reaching responses in up to 80% of cases. Danazol and oxymetholone are more commonly used, but virilization and liver toxicity are major adverse events. Diamond-Blackfan anemia is commonly treated with corticosteroids, but most patients eventually become refractory to this treatment and toxicity is limiting. Growth factors still have a role in inherited cases, especially granulocyte colony-stimulating factor in congenital neutropenias. Novel therapies are warranted and thrombopoietin receptor agonists, leucine, quercetin, and novel gene therapy approaches may benefit inherited cases in the future.

Oxymetholone therapy of fanconi anemia suppresses osteopontin transcription and induces hematopoietic stem cell cycling

Androgens are widely used for treating Fanconi anemia (FA) and other human bone marrow failure syndromes, but their mode of action remains incompletely understood. Aged Fancd2^−/− mice were used to assess the therapeutic efficacy of oxymetholone (OXM) and its mechanism of action. Eighteen-month-old Fancd2^−/− mice recapitulated key human FA phenotypes, including reduced bone marrow cellularity, red cell macrocytosis, and peripheral pancytopenia. As in humans, chronic OXM treatment significantly improved these hematological parameters and stimulated the proliferation of hematopoietic stem and progenitor cells. RNA-Seq analysis implicated downregulation of osteopontin as an important potential mechanism for the drug’s action. Consistent with the increased stem cell proliferation, competitive repopulation assays demonstrated that chronic OXM therapy eventually resulted in stem cell exhaustion. These results expand our knowledge of the regulation of hematopoietic stem cell proliferation and have direct clinical implications for the treatment of bone marrow failure.

Androgens for the anaemia of chronic kidney disease in adults

BACKGROUND

Anaemia occurs when blood contains fewer red blood cells and lower haemoglobin levels than normal, and is a common complication among adults with chronic kidney disease (CKD). Although a number of approaches are applied to correct anaemia in adults with CKD, the use of androgen therapy is controversial.

OBJECTIVES

The aim of this review was to determine the benefits and harms of androgens for the treatment of anaemia in adult patients with CKD.

SEARCH METHODS

We searched CENTRAL, the Cochrane Renal Group's Specialised Register, the Chinese Biomedicine Database (CBM), CNKI, VIP and reference lists of articles without language restriction. The most recent search was conducted in August 2014.

SELECTION CRITERIA

All randomised controlled trials (RCTs) that assessed the use of androgens for treating anaemia of CKD in adults were eligible for inclusion.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted data and assessed risk of bias in the included studies. Meta-analyses were performed using relative risk (RR) for dichotomous outcomes and mean differences (MD) for continuous outcomes, with 95% confidence intervals (CI).

MAIN RESULTS

We included eight studies that reported data from 181 participants. Study quality was assessed as moderate in six studies, one was low quality, and one was high quality. The small number of included studies, and low participant numbers adversely influenced evidence quality overall.We found limited evidence (1 study, 24 participants) to indicate that oxymetholone can increase haemoglobin (Hb) (MD 1.90 g/dL, 95% CI 1.66 to 2.14), haematocrit (HCT) (MD 27.10%, 95% CI 26.49 to 27.71), change in albumin (MD 4.91 g/L, 95% CI 3.69 to 6.13), alanine aminotransferase (ALT) (MD 54.50 U/L, 95% CI 43.94 to 65.06), and aspartate aminotransferase (AST) (MD 47.33 U/L, 95% CI 37.69 to 56.97); and decrease high-density lipoprotein (HDL) (MD -15.66 mg/dL, 95% CI -24.84 to -6.48). We also found that compared with erythropoietin alone, nandrolone decanoate plus erythropoietin may increase HCT (3 studies, 73 participants: MD 2.54%, 95% Cl 0.96 to 4.12). Compared with erythropoietin (1 study, 27 participants), limited evidence was found to suggest that nandrolone decanoate can increase plasma total protein (MD 0.40 g/L, 95% CI 0.13 to 0.67), albumin (MD 0.20 g/L, 95% CI 0.01 to 0.39), and transferrin (MD 45.00 mg/dL, 95% CI 12.61 to 77.39) levels. Compared with no therapy (remnant kidney), evidence was found to suggest that nandrolone decanoate can increase Hb (2 studies, 33 participants: MD 1.04 g/dL, 95% Cl 0.66 to 1.41) and HCT (1 study, 24 participants: MD 3.70%, 95% Cl 0.68 to 6.72). Compared with no therapy (anephric), evidence was found (1 study, 5 participants) to suggest that nandrolone decanoate can increase Hb (MD 1.30 g/dL, 95% Cl 0.57 to 2.03), but nandrolone decanoate did not increase HCT (MD 2.00%, 95% Cl -0.85 to 4.85).However, oxymetholone was not found to reduce blood urea nitrogen (BUN), serum creatinine (SCr), cholesterol, or triglycerides; or increase plasma total protein, prealbumin, or transferrin. No evidence was found to indicate that nandrolone decanoate increased prealbumin or decreased BUN, SCr, AST, ALT, cholesterol, triglycerides, HDL or low-density lipoprotein (LDL). Adverse events associated with androgen therapy were reported infrequently.

AUTHORS' CONCLUSIONS

We found insufficient evidence to confirm that use of androgens for adults with CKD-related anaemia is beneficial.

Does anything work for anaemia in myelofibrosis?

Anaemia is a common finding at diagnosis in myelofibrosis, and becomes a symptomatic problem in most patients with time. There are several treatment options for specific anaemia treatment, none of which has been tested in large, randomized, controlled trials. However, as myelofibrosis is not a disease with spontaneous remissions, even non-randomized trials carry weight. In this survey, the existing evidence will be analysed, both for the commonly used treatments like erythropoiesis-stimulating agents, androgens and thalidomide and for the new drugs in the area, and conclusions will be drawn concerning standard clinical anaemia treatment in myelofibrosis, which according to evidence from studies has a 40-50% chance of response in patients with not too advanced disease.

Improvement in erythropoieis-stimulating agent-induced pure red-cell aplasia by introduction of darbepoetin-α when the anti-erythropoietin antibody titer declines spontaneously

Anti-erythropoietin antibodies usually cross-react with all kinds of recombinant erythropoietins; therefore, erythropoiesis-stimulating agent (ESA)-induced pure red-cell aplasia (PRCA) is not rescued by different ESAs. Here, we present a case of ESA-induced PRCA in a 36-yr-old woman with chronic kidney disease, whose anemic condition improved following reintroduction of darbepoetin-α. The patient developed progressive, severe anemia after the use of erythropoietin-α. As the anemia did not improve after the administration of either other erythropoietin-α products or erythropoietin-β, all ESAs were discontinued. Oxymetholone therapy failed to improve the transfusion-dependent anemia and a rechallenge with ESAs continuously failed to obtain a sustained response. However, her anemia improved following reintroduction of darbepoetin-α at 3 yr after the initial diagnosis. Interestingly, anti-erythropoietin antibodies were still detectable, although their concentration was too low for titration. In conclusion, darbepoetin-α can improve ESA-induced PRCA when the anti-erythropoietin antibody titer declines and its neutralizing capacity is lost.

Oral oxymetholone reduces mortality induced by gamma irradiation in mice through stimulation of hematopoietic cells

Oxymetholone is a 17alpha -alkylated anabolic-androgenic steroid. This drug can stimulate bone marrow cells and increase the blood cells in the peripheral blood vessels. It has been used for the treatment of anemia caused by low red cell production. Since oxymetholone has hematopoietic effect, we studied radioprotective effects of this drug in mice. In this study, we determined percentage of survival, dose-reduction factor (DRF) and hematological parameters in irradiated mice which treated with or without oxymetholone. Oxymetholone administrated at different doses 80, 160, 320, 640 mg/kg by gavages at 24 h before 8 Gy gamma irradiation. At 30 days after treatment, the following percentage of animals survival in each group was as: 80 mg/kg, 50%; 160 mg/kg, 50%; 320 mg/kg, 55%; 640 mg/kg, 75% and vehicle, 15%. Percentage of survival increased in all of treated groups statistically compared with irradiated-vehicle group. In the groups treated by oxymetholone, maximum protection was realized at 640 mg/kg. In order to calculate the DRF for oxymetholone, mice were exposed to whole-body gamma irradiation with dose ranges between 5.83 and 11.23 Gy. The probit line for oxymetholone-treated mice was shifted to the right with a DRF of 1.14. In mice exposed to whole-body gamma-irradiation (4 Gy), an oral administration of 640 mg/kg oxymetholone ameliorated radiation-induced decreases in circulating platelets and erythrocytes, but had a less effect on total number of WBC. These results demonstrate that oxymetholone stimulates myelopoiesis and thrombocytopenia and enhances survival in mice after ionizing radiation.

Clonal monosomy 7 in a megakaryoblastic leukemia developed on the basis of Fanconi anemia

A 13-year-old girl with a history of Fanconi anemia developed acute myeloid leukemia of the M7 subtype with a 45,XX,-7 karyotype, which is rare in M7 subtype. Treatment protocols were set up, but she died of sepsis and osteomyelitis during induction.

Testosterone replacement for hypogonadism: clinical findings and best practices

Hypogonadism is highly prevalent in HIV-infected patients and has been associated with the late stages of AIDS and AIDS wasting. There are a number of studies exploring treatment options. Testosterone replacement, with the exception of the transscrotal delivery patch, has been observed to have a beneficial effect on lean body mass and body weight in hypogonadal and eugonadal men with the AIDS wasting syndrome. Resistance exercise training also has had favorable effects on body weight and muscle cell mass. In hypogonadal men with AIDS treated with testosterone replacement therapy, researchers noted a positive effect on depression scores.

Littoral cell angioma of the spleen in a patient with severe aplastic anaemia

Littoral cell angioma (LCA) is a rare benign tumour of the spleen. We describe a patient with aplastic anaemia who, following multiple treatments with rabbit and horse Anti-Thymocyte Globulin and anabolic steroids developed marked splenomegaly and hypersplenism. LCA was diagnosed post splenectomy. This is the first case of LCA associated with aplastic anaemia and its treatment.

Inherited aplastic anaemia

A number of inherited (constitutional/genetic) disorders are characterized by bone marrow (BM) failure/aplastic anaemia (AA) usually in association with one or more somatic abnormality. Occasionally, these patients may present with AA alone and be labelled to have idiopathic AA. In recent years, there have been significant advances in the genetics of Fanconi anaemia (FA), dyskeratosis congenita (DC) and other BM failure syndromes. This is facilitating accurate diagnosis and beginning to unravel their pathophysiology. Furthermore, these advances are also providing important insights into normal haemopoiesis and how this might become defective in some patients presenting with the more common idiopathic AA. Indeed, a link between DC and idiopathic AA and in turn to defective telomerase has now been established. This advance also suggests that treatments directed at correction of telomerase activity might benefit AA patients who do not respond to conventional therapy.

Oxymetholone for the treatment of HIV-wasting: a double-blind, randomized, placebo-controlled phase III trial in eugonadal men and women

BACKGROUND

Despite highly active antiretroviral therapy (HAART), chronic involuntary weight loss still remains a serious problem in the care of HIV patients due to various alterations in energy metabolism and endocrine regulation. Previous studies in HIV-positive men undergoing androgen replacement therapy or treatment with recombinant growth hormone (rGH) have shown partial restoration of lean body mass (LBM), but these treatments have largely not been sufficiently studied in eugonadal individuals.

METHOD

A double-blind, randomized, placebo-controlled trial of 89 HIV-positive eugonadal women and men with wasting assigned to the anabolic steroid oxymetholone (50 mg bid or tid) or placebo for 16 weeks was performed. Body weight, bioimpedance measurements, quality of life parameters, and appetite were analyzed.

RESULTS

Oxymetholone led to a significant weight gain of 3.0 +/- 0.5 and 3.5 +/- 0.7 kg in the tid and bid groups, respectively (p <.05 for each treatment versus placebo), while individuals in the placebo group gained an average of 1.0 +/- 0.7 kg. Body cell mass (BCM) increased in the oxymetholone bid group (3.8 +/- 0.4 kg; p <.0001) and in the oxymetholone tid group (2.1 +/- 0.6 kg; p <.005). Significant improvements were noted in appetite and food intake, increased wellbeing, and reduced weakness by self-examination. The most important adverse event was liver-associated toxicity. Overall, 43% of patients in the tid group, 25% of patients in the bid oxymetholone group, and 8% in the placebo group had a greater than 5 times baseline increase for ALT, AST, or gamma GT, while other adverse events were not increased over placebo.

CONCLUSION

Oxymetholone can be considered an effective anabolic steroid in eugonadal male and female patients with AIDS-associated wasting. The bid (100 mg/day) regimen appeared to be equally effective to the tid (150 mg/day) regimen in terms of weight gain, LBM, and BCM and was associated with less liver toxicity.

Double-blind, randomized, placebo-controlled phase III trial of oxymetholone for the treatment of HIV wasting

BACKGROUND

Despite highly active antiretroviral therapy (HAART), chronic involuntary weight loss still remains a serious problem in the care of HIV patients. Various alterations in energy metabolism and endocrine regulation have been found to cause loss of lean body mass (LBM) and body cell mass (BCM). Previous studies in HIV-positive men undergoing androgen replacement therapy or treatment with recombinant growth hormone (rGH) have shown partial restoration of LBM, but these treatments have largely been ineffective in eugonadal individuals.

STUDY DESIGN

Double-blind, randomized, placebo-controlled trial of 89 HIV-positive women and men with wasting assigned to the anabolic steroid oxymetholone [50 mg twice (BID) or three times daily (TID)] or placebo for 16 weeks followed by open-label treatment. STUDY ENDPOINTS: Body weight, bioimpedance measurements, quality of life parameters and appetite.

RESULTS

Oxymetholone led to a significant weight gain of 3.0 +/- 0.5 and 3.5 +/- 0.7 kg in the TID and BID groups, respectively (P < 0.05 for each treatment versus placebo), whereas individuals in the placebo group gained an average of 1.0 +/- 0.7 kg. Body cell mass increased in the oxymetholone BID group (3.8 +/- 0.4 kg; P < 0.0001) and in the oxymetholone TID group (2.1 +/- 0.6 kg; P < 0.005), corresponding to 12.4 and 7.4% of baseline BCM, respectively. Significant improvements were noted in appetite and food intake, increased well-being and reduced weakness by self-examination. The most important adverse event was liver-associated toxicity. Overall, 35% of patients in the TID, 27% of patients in the BID oxymetholone group and no patients in the placebo group had a greater than five times baseline increase for alanine aminotransferase during the double-blind phase of the study.

CONCLUSIONS

Oxymetholone can be considered an effective anabolic steroid in eugonadal male and female patients with AIDS-associated wasting. The BID (100 mg/day) regimen appeared to be equally effective as the TID (150 mg/day) regimen in terms of weight gain, LBM and BCM and was associated with less, but still significant liver toxicity.

Aplastic anemia complicating systemic lupus erythematosus--report of a case and review of the literature

Aplastic anemia is a very unusual feature of systemic lupus erythematosus (SLE). A 32-year-old lady presented with generalized purpuric lesions and was diagnosed as having immune thrombocytopenic purpura. Fourteen months later, she developed progressive pancytopenia, arthritis of small joints, and oral ulcers. Investigations confirmed SLE with aplastic anemia. High-dose methylprednisolone therapy had been unsuccessful in controlling the pancytopenia. She had a progressive course and died due to septicemia. Even though pancytopenia is common in SLE, a bone marrow examination should be done in all cases of persistent pancytopenia to exclude bone marrow aplasia. This will help in tailoring the treatment with more aggressive immunosuppressants.

Review of oxymetholone: a 17alpha-alkylated anabolic-androgenic steroid

BACKGROUND

Oxymetholone (17beta-hydroxy-2-[hydroxymethylene]-17-methyl-5alpha-androstan-3-one) is a 17alpha-alkylated anabolic-androgenic steroid and a synthetic derivative of testosterone. It has been approved by the US Food and Drug Administration for the treatment of anemias caused by deficient red cell production.

OBJECTIVES

This review summarizes the pharmacokinetics, current and future clinical applications, and adverse effects of oxymetholone. Relevant studies were identified using a search of MEDLINE through March 2001, supplemented by conference abstracts and presentations.

RESULTS

Because of its anabolic properties, oxymetholone has been studied for the treatment of HIV-associated wasting, antithrombin III deficiency, pediatric growth impairment, and damaged myocardium, with varying degrees of success. Hepatotoxicity is a major adverse effect associated with the use of oxymetholone, with cholestatic jaundice the most important hepatic side effect. Less common hepatic side effects associated with the use of anabolic-androgenic steroids include peliosis hepatis and formation of hepatic tumors. All anabolic-androgenic steroids can cause androgenic side effects, including acne, hirsutism, hair loss, clitoral/phallic enlargement, vocal changes, erectile tissue stimulation, gynecomastia, amenorrhea, and changes in libido and sexual potency.

CONCLUSIONS

As is the case with many anabolic-androgenic steroids, few pharmacokinetic and tolerability studies were performed before oxymetholone's approval in the 1960s. It has proved, however, to be an appropriate treatment choice for selected patients with anemia, if carefully monitored.

Ampullary carcinoma developing after androgenic steroid therapy for aplastic anemia: Report of a case

Sex steroids influence the development and course of human genital carcinomas including breast, testis, prostata, and ovarian cancers. (1) Other carcinomas such as hepatoma, cholangioma, and pancreatic cancer have also been reported to be related to sex hormones. (2-4) The existence of sex hormone receptors has been demonstrated immunohistochemically in specimens of these diseases. We recently encountered a patient in whom an ampullary carcinoma developed 39 months after the start of androgenic steroid therapy for aplastic anemia. Immunohistochemic analysis of resected tumor specimens of the patient suggested a possible hormonal effect on the tumor oncology.

Multiple hepatic adenomas caused by long-term administration of androgenic steroids for aplastic anemia in association with familial adenomatous polyposis

We report a rare case of hepatic adenomas (HA), in a 20-year-old Japanese girl treated for 6 years with anabolic androgens for aplastic anemia. In a review of the world literature using computer MEDLINE search, we found only 17 cases of androgen-induced HA published between 1975 and 1998 in the English-language literature. The patient was referred to us because of liver lesions detected during a follow-up examination for familial adenomatous polyposis. After being diagnosed with aplastic anemia at 14 years of age, she had been treated with oxymetholone (30 mg/day) for 6 years. Laboratory evaluation revealed normal liver function. Ultrasonography (US) and computed tomography (CT) demonstrated multiple liver lesions. Histopathological examinations of biopsied specimens from the liver tumor showed HA. After the patient was diagnosed with HA, oxymetholone was tapered off. Patients taking androgenic-anabolic steroids should be carefully monitored with US and CT and tumor markers should be measured. This report may be helpful in identifying the population who is at risk of developing hepatic sex hormone-related tumors.

Refractory anemia with excess of blasts: increased survival when treated with cyclophosphamide, methotrexate and 6-mercaptopurine

Owing to the lack of efficacious treatments for refractory anemia with an excess of blasts (RAEB), evaluation of other therapeutic strategies is necessary, especially in elderly patients. We report herein our experience with an oral triple drug regimen with cyclophosphamide 200 mg/m2 and methotrexate 20 mg/m2 once a week, and 6-mercaptopurine 50 mg/m2 daily for the treatment of RAEB. Eighteen patients with a median age of 62 yr (range 17-80) received a triple drug regimen (TDR), and they were compared with 6 patients who received oxymetholone (2 mg/m2/d) and 9 who received supportive therapy only. Partial response was achieved in 45% of patients receiving TDR. In 77% of patients treated with TDR the number of bone marrow blasts decreased to <5%; however, they persisted with trilineage dyspoietic morphologic changes. Median survival for TDR was 23 months (range 1-96), which was longer than that for the other groups. A slight rise in liver enzymes was the only side effect of TDR. TDR seems to be a useful alternative in patients with RAEB, a finding to be confirmed in further prospective studies.

A case of aplastic anaemia in pregnancy

Aplastic anaemia in pregnancy is an extremely rare condition with high maternal morbidity and mortality rates. Intensive haematological support remains the mainstay of therapy and a successful obstetric outcome can be best accomplished with the close clinical collaboration of the haematologist and the obstetrician as occurred with our patient reported here.

Abnormal cytogenetic clones in patients with aplastic anaemia: response to immunosuppressive therapy

We report the response to immunosuppressive therapy with antithymocyte globulin (ATG) and cyclosporin or oxymetholone in 13 cases of aplastic anaemia (AA) with an abnormal cytogenetic clone detected at or sometime after diagnosis. Blood and bone marrow examination showed no distinctive morphological features of myelodysplasia (MDS) at diagnosis. Haematological response occurred promptly in eight cases; the remainder responded after additional immunosuppression with or without oxymetholone. Three patients had a late relapse of AA, treated successfully by allogeneic bone marrow transplantation in one; the others responded to oxymetholone. Transformation to MDS or acute leukaemia was not observed after a median follow-up of 4.1 years (range 1.2-11.2). In four patients the cytogenetic clone disappeared after treatment.

A patient with non-A, non-B, non-C hepatitis-associated aplastic anemia recovered promptly following immuno-suppressive therapy, including antithymocyte globulin

A 21-year-old male patient with non-A, non-B, non-C acute hepatitis was complicated by hepatitis-associated severe aplastic anemia during hospitalization for active hepatitis. He was promptly diagnosed and treated with methylprednisolone, anabolic steroids, cyclosporin A, granulocyte colony-stimulating factor (G-CSF), and antithymocyte globulin (ATG). He responded quickly to the immuno-suppressive therapy and was transfusion independent after 25 days and granulocyte colony-stimulating factor independent at 57 days after ATG therapy. Although the etiology of hepatitis-associated aplastic anemia is still controversial, the authors emphasized the importance to carefully follow non-A, non-B, non-C hepatitis patients without aplastic anemia for more than three months after hepatitis episodes in order to improve outcome of this lethal disease.

Analysis of 65 Turkish patients with congenital aplastic anemia (Fanconi anemia and non-Fanconi anemia): Hacettepe experience

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.

Antilymphocyte globulin (ALG) or antithymocyte globulin (ATG) with methylprednisone and oxymethalone in aplastic anaemia

From 1986 to 1994 we treated 26 patients of aplastic anaemia between 6 to 61 years age group with ATG/ALG, Methylprednisone and Oxymethalone. Five had very severe aplastic anaemia, 16 had severe and 5 nonsevere disease. Disease was associated with hepatitis in 5 patients and with pregnancy and drug use in 2 patients each. In others no cause could be ascertained. A total of 31 courses of treatment were given (range 1-3 courses per patient). Nine patients had complete response (34.62%) and 3 had partial response (11.54%) with an overall response rate of 46.16%. Four patients died within 2 months of starting the treatment. The median follow up was 24 months (range 6-102 months) with an overall survival probality of 45% at 2 yr. At the time of evaluation 12 patients have died, 9 are alive disease-free and 5 are alive with disease. The side effects associated with therapy were tolerable and did not require cessation of therapy in any patient. We conclude that ATG/ALG with Methylprednisone and Oxymethalone is beneficial to significant number of patients with aplastic anaemia.

Treatment results of 23 cases of severe aplastic anemia with lymphocytapheresis

We report the results of 23 patients with aplastic anemia (AA) treated with a program of 14 lymphocytapheresis (LC). Treatments were performed with apheresis machines, models Haemonetics 30-S and Baxter CS3000, using the standard program. This procedure was done because AA in many cases appears as a result of the action of a T cell population that inhibits hematopoiesis. Theoretically, removal of this clonal population would produce hematopoietic recovery. Of the total of 23 patients, 9 were excluded for final evaluation of treatment results because 7 died during or shortly after treatment (0.7-3 months); one patient abandoned treatment after three LC and another died 7 months later because of transformation to acute leukemia. The remaining 14 patients were included in the final evaluation of treatment; seven females and seven males, average age 46.1 years (range 22-69); 13 with severe, and one with moderate AA; 11 with recently diagnosed, and 3 with chronic AA; 12 without previous treatment and two treated before with antilymphocyte globulin + oxymetholone (OXM) + cyclosporine A (CsA) with transient partial remission (PR). Besides lymphocytapheresis, 13 patients received OXM; 4 of them GM-CSF and one low dose CsA. Four patients had complete remission lasting > 59.5 months (range 42-78); eight PR (average duration of > 38.6 months), and two minimal remission (> 37 and 29 months). Platelet, reticulocyte and granulocyte counts increased on average at 48.7, 73.3 and 91.4 days, respectively. In conclusion, 14 (60.8%) of 23 patients with AA showed an improvement related to LC treatment, with a survival probability of 63% from the fourth month, the latter with an added beneficial effect of the other therapies used. Larger numbers of patients have to be treated with LC to determine its real usefulness, mechanism of action and the best conditions for its use.

Hepatocellular carcinoma associated with anabolic steroid therapy: report of a case and review of the Japanese literature

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.

Oxymetholone promotes weight gain in patients with advanced human immunodeficiency virus (HIV-1) infection

The effect of the testosterone derivative oxymetholone alone or in combination with the H1-receptor antagonist ketotifen, which has recently been shown to block tumour necrosis factor alpha (TNF alpha), on weight gain and performance status in human immunodeficiency virus (HIV) patients with chronic cachexia was evaluated in a 30-week prospective pilot study. Thirty patients were randomly assigned to either oxymetholone monotherapy (n 14) or oxymetholone plus ketotifen (n 16). Patients receiving treatment were compared with a group of thirty untreated matched controls, who met the same inclusion criteria. Body weight and the Karnofsky index, which assesses the ability to perform activities of daily life, and several quality-of-life variables were measured to evaluate response to therapy. The average weight gain at peak was 8.2 (SD 6.2) kg (+ 14.5% of body weight at study entry) in the oxymetholone group (P < 0.001), and 6.1 (SD 4.6) kg (+10.9%) in the combination group (P < 0.005), compared with an average weight loss of 1.8 (SD 0.7) kg in the untreated controls. The mean time to peak weight was 19.6 weeks in the monotherapy group and 20.8 weeks in the combination group. The Karnofsky index improved equally in both groups from 56% before to 67% after 20 weeks of treatment (P < 0.05). The quality of life variables (activities of daily life, and appetite/nutrition) improved in 68% (P < 0.05) and 91% (P < 0.01) of the treated patients respectively. Oxymetholone was safe and promoted weight gain in cachectic patients with advanced HIV-1 infection. The addition of ketotifen did not further support weight gain. These results suggest the need for a randomized, double-blind, placebo-controlled multicentre trial.

[Results of treatment for severe acquired aplastic anemia in children]

The authors evaluated results of treatment of 106 children with acquired aplastic anemia. The patients were divided into 3 groups depending on the severity of their disease. Thirty-nine patients were classified as very severe, 30 as severe and 37 as non-severe according to the modified Camitta criteria. Among them, 47 children were treated with oxymetholone and prednisolone. In this group 32 died. Antilymphocyte globulin (ALG) was given to 48 patients and 20 received cyclosporin A (CsA). The results obtained by these two methods are nearly the same and 5 year survival was 61% and 59% respectively. Bone marrow was transplanted in only one child, who is still in complete remission. Statistical analysis showed a steady increase in incidence of aplastic anemia in the years 1987-1989, which might coincide with the Czarnobyl explosion. However, further research is required to prove this point.

Treatment of aplastic anaemia (AA) with antilymphocyte globulin (ALG) and methylprednisolone (MPred) with or without androgens: a randomized trial from the EBMT SAA working party

134 patients with acquired aplastic anaemia (AA) were given HALG 15 mg/kg/d for 5 d and methylprednisolone for 1 month, and randomized to receive (n = 69) or not (n = 65) oxymetholone 2 mg/kg/d p.o. daily for 4 months. Early mortality (< 120 d) was comparable in the two arms 12/69 (17%) and 11/65 (17%), and correlated with the severity of the disease (39%, 10% and 6% respectively in patients with neutrophil counts (PMN) < 0.2, 0.2-0.5, > 0.5 x 10(9)/l). The response rate at 120 d was significantly greater in patients receiving androgens (56% v 40%; P = 0.04); it was 68% v 48% (P = 0.02) in patients surviving 120 d, and 78% v 27% (P = 0.03) in females with PMN less than 0.5 x 10(9)/l. In a multivariate Cox analysis on patients with less than 0.5 x 10(9)/l PMN, the probability of responding without androgens was reduced compared to the androgen treatment arm (P = 0.05). Survival was comparable in the two groups (71% v 65%). It was superior (74% v 50%), but not significantly (P = 0.1) in females with PMN < or = 0.5 x 10(9)/l receiving androgens. Side-effects, including biochemical abnormalities and virilization, could be controlled and were reversible. In conclusion, the addition of androgens to HALG and methylprednisolone as first line treatment of aplastic anaemia significantly improves the response rate at 4 months, particularly in females with low neutrophil counts, although there is no significant effect on short-term survival. The reversible side-effects warrant the use of androgens as an adjunct to the first course of ALG in females with severe AA.

Serum immunoreactive erythropoietin in patients with idiopathic aplastic and Fanconi's anaemias

In patients with idiopathic aplastic anaemia (n = 34) and Fanconi's anaemia (n = 8), sampled once or on several occasions, serum erythropoietin (Epo) increased with increasing severity of anaemia with apparently similar rates of increase in each group. However, after adjustment for Hb, log Epo values for the Fanconi's anaemics tended to be greater than those for the idiopathic aplastic anaemics (P < 0.01). Erythropoietin concentrations in serum samples from patients with Fanconi's and idiopathic aplastic anaemias tended to be greater than in samples from patients with anaemias from protein energy malnutrition, myelodysplasia and iron deficiency. The results suggest that there is no deficiency of erythropoietin in Fanconi's and idiopathic aplastic anaemias and that if exogenous erythropoietin is of any benefit it would need to be administered in doses large enough to induce a significant increase in log Epo. Results of the study illustrate the need to take account of the assumptions which underlie interpretation of the statistical analysis. Use of erythropoietin values in place of log Epo gives misleading conclusions demonstrable as invalid as the conditions for normality of distribution of the data and homogeneity of variances were not satisfied.

Aplastic anaemia: a review of cases at the University College Hospital, Ibadan, Nigeria

Thirty male and 27 female patients were treated at the University College Hospital, Ibadan, over a 20 year period (January, 1971 to December, 1990) for aplastic anaemia. Age range was three months to 52 years with a median of 19 years. In 26 patients the aplasia could not be linked with a particular cause. Most patients in this category were students in secondary and tertiary institutions, office workers and casual labourers. Nineteen patients were automobile and factory workers who are exposed to lead while two were dealers in petroleum products. In two patients aplasia was linked to chloramphenicol ingestion while in three, the aplasia linked to the use of hair dye. Another three linked the aplasia to a past history of viral hepatitis. One patient had congenital aplasia of the marrow and one was a radiographer. Treatment included oxymethalone 100 mg given three times daily (tds) or intramuscular (i.m.) Durabolin 500 mg weekly. When these drugs were unavailable prednisolone 60 mg daily was administered. No patient had the benefit of bone marrow transplantation (BMT) or the superior drugs, e.g. anti-thymocyte globulin and cyclosporin A. This might have contributed to the poor prognosis as revealed by the survival pattern in which 24 patients died within six months of diagnosis while 19 survived 12 months. Seven patients died within 18 months and four others died within three years. Three patients were alive five years after presentation. Death generally resulted from complications of the aplastic anaemia with gastro-intestinal bleeding, cerebro-vascular accidents and overwhelming infections.

Acquired amegakaryocytic thrombocytopaenia in a child

A boy aged 5 years is described with amegakaryocytic thrombocytopaenia, which was associated with defective granulopoiesis and erythropoiesis, but did not evolve into marrow aplasia. Marrow cultures confirmed the presence of abnormalities in each of the haemopoietic lineages and identified defective maturation of megakaryocytic precursors. The was no evidence of a humoral inhibitor of megakaryopoiesis. The patient's blood cell counts responded to treatment with oxymetholone.

Immunosuppressive therapy of aplastic anemia: results of a prospective, randomized trial of antithymocyte globulin (ATG), methylprednisolone, and oxymetholone to ATG, very high-dose methylprednisolone, and oxymetholone

Sixty-eight patients with moderate (n = 15) or severe (n = 53) aplastic anemia were entered into a prospective, randomized, two-arm treatment study comparing antihuman thymocyte globulin (ATG), lower-dose methylprednisolone (LDM) and oxymetholone to ATG, higher-dose methylprednisolone (HDM), and oxymetholone. There were no differences between the two groups when comparing age, sex, etiology of aplasia, disease duration, severity of aplasia, or pretherapy granulocyte counts. Side effects of LDM and HDM were similar. Of the 64 patients evaluable for response to therapy, 12 of 33 (36%) who received LDM had complete, partial, or minimal responses compared with 15 of 31 patients (48%) who received HDM (P = .33). Actuarial survival at 4 years is 43% for patients in the LDM group and 47% for patients in the HDM group (P = .99). Causes of death included hemorrhage, infection, evolution to acute leukemia, and complications of subsequent bone marrow transplantation. Long-term complications included paroxysmal nocturnal hemoglobinuria (n = 3), evolution to myelodysplasia or acute leukemia (n = 6), and recurrent aplasia (n = 6). We were unable to show a significant difference in toxicity, response rate, or survival for patients treated with ATG, oxymetholone, and LDM compared with patients who received ATG, oxymetholone, and HDM.

A child with xeroderma pigmentosum and bone marrow failure

The case of a child with both xeroderma pigmentosum and bone marrow failure is reported. It is suggested that this is not a chance association, and that the bone marrow hypoplasia may reflect an increased susceptibility of this patient's haemopoietic stem cells to non-UV mutagens.

A clinico-haematologic profile of paroxysmal nocturnal haemoglobinuria

Clinico-haematological parameters in sixteen patients of paroxysmal nocturnal haemoglobinuria (PNH) are presented. Their modes of presentation included recurrent episodes of cola-coloured urine (6/16), refractory anaemia (9/16) and predominant thrombotic manifestations (1/16). Laboratory investigations revealed the presence of anaemia (16/16), reticulocytosis (14/16), thrombocytopenia (11/16), leucopenia (5/16) and cellular bone marrow (14/16). Two patients had hypoplastic bone marrow initially but subsequently developed PNH. The patients were treated with haematinics, prednisolone (16/16) and oxymethalone (2). Prednisone was effective in suppressing haemolytic episodes. Oxymethalone given to the 2 patients with hypoplastic bone marrow resulted in amelioration of anaemia in one but no effect in the other patient.

Hepatocellular carcinoma and squamous cell carcinoma in a patient with Fanconi's anemia

Acute leukemia, hepatocellular carcinoma, and squamous cell carcinoma have been reported in patients with Fanconi's anemia. We report on a 31-year-old woman who developed squamous cell carcinoma of the esophagus and hepatocellular carcinoma. Jaundice and hepatic tumor developed in 1981, after she had received oxymetholone for 10 years. Liver biopsy revealed peliosis hepatis. Androgenic therapy was stopped and the jaundice resolved. However, the hepatic tumor was observed to be unchanged. The patient died of disseminated squamous cell carcinoma, but no metastatic lesions from hepatocellular carcinoma were detected in the autopsy. The association of Fanconi's anemia and squamous cell carcinoma is reviewed, and the malignant potential of androgen-related hepatic tumors is discussed.

Acquired aplastic anaemia: still a serious disease

Over 15 years, 42 children aged 2-14 years were diagnosed as having acquired aplastic anaemia. Adequate clinical details were available for 38 children who were categorised as very severe (n = 13), severe (n = 16), or nonsevere (n = 9) by the modified Camitta criteria. Treatment varied over the study period. Seven children received a bone marrow allograft from a full match family donor and three a matched unrelated donor transplant after failed treatment with antilymphocyte globulin. The remainder were treated with antilymphocyte globulin (n = 11), antilymphocyte globulin and oxymetholone (n = 4), oxymetholone with or without prednisolone (n = 12), or supportive treatment alone (n = 1). With a minimum follow up of one year since treatment, the five year survival was 70% for bone marrow transplantation with a family donor, 30% for antilymphocyte globulin, and 25% for oxymetholone. All three children with a matched unrelated donor transplant died. The prognosis of acquired aplastic anaemia remains poor for most children and new approaches to treatment are urgently required.

Hairy cell leukemia. A therapeutical update

This is a review of current treatment for hairy cell leukemia (HCL). Data for this analysis were obtained from the Italian HCL Registry, as well as from other published series. We have given space to the impact of interferon and pentostatin on the management of this disease. Other issues are also discussed, such as the relevance of achieving a complete remission with respect to overall and relapse-free survival. We include a final section on recommendations which may prove useful in designing an appropriate therapeutic strategy.

Oxymetholone therapy in patients with familial antithrombin III deficiency

Three patients with familial antithrombin III (ATIII) deficiency, who also have histories of thromboembolism, were treated with oxymetholone in combination with warfarin. Thrombolysis was observed in one patient with acute thrombosis of inferior vena cava during the oxymetholone and warfarin therapy. No further thromboembolic episodes occurred in these patients after initiation of warfarin with or without oxymetholone. The levels of plasma ATIII, alpha 1-antitrypsin, plasminogen and Cl-inactivator were significantly increased in all patients after the introduction of oxymetholone therapy. This suggests that oxymetholone augments anticoagulant and fibinolytic activity. Hence we consider that oxymetholone in combination with warfarin may be possible thrombolytic therapy in patients with familial ATIII deficiency.

Treatment of aplastic anemia with antithymocyte globulin, high-dose corticosteroids, and androgens

A total of 46 patients with aplastic anemia (34 severe; 12 moderate) were treated with antihuman thymocyte globulin (ATG), high-dose methylprednisolone, and oxymetholone. Early symptoms of ATG toxicity included fever, rash, and bronchospasm. Signs of serum sickness also developed in 23 patients. Complications associated with high doses of steroids were hyperglycemia, hypertension, fluid retention, gastrointestinal hemorrhage, and aseptic necrosis of the hip. Other morbidity possible associated with steroid administration included seizures, arrhythmias, and headache with papilledema. Studies of elevated liver function necessitated discontinuation of androgen therapy in eight patients. A complete or partial hematological response was noted in 19 patients (41%). Of these, three have had recurrent cytopenias, of whom one has developed a myelodysplastic syndrome. There are currently 34 patients surviving, and 12 who have died. Actuarial survival at three years is 65%. These response and survival data are comparable to those of previous trials using ATG and androgens without high-dose steroids. A prospective, randomized trial is needed to determine whether the addition of high-dose corticosteroids to ATG does significantly increase the rate and frequency of response in order to justify the toxicity of this additional immunosuppressive therapy in the treatment of aplastic anemia.

Hairy cell leukemia. Durability of response to splenectomy in 26 patients and treatment of relapse with androgens in six patients

Twenty-three of 26 patients with hairy cell leukemia evaluable for response to splenectomy had significant improvement in anemia, thrombocytopenia, and/or neutropenia. Eight of the 23 had a recurrence of cytopenia after a median response duration of 4 to 5 months (range, 1-22). The remaining 15 patients did not have a recurrence of cytopenia at 20 months median follow-up (range, 1-76). Six patients with postsplenectomy cytopenia were given androgenic steroids. Two of the six had an improvement in anemia and thrombocytopenia, and a third patient had an improvement in neutropenia. It was concluded that, although most patients with hairy cell leukemia have initial improvement in cytopenia with splenectomy, a significant number of them either fail to respond or have recurrent cytopenia after initial response to splenectomy. A trial of androgenic steroids is a reasonable therapeutic option in these patients. Alternative therapies are reviewed and recommendations made.
