Forty-three patients with myelodysplastic syndromes (MDS) received treatment with oral etoposide 50 mg/day for 21 consecutive days every 4 weeks. Eighteen patients (42%) experienced hematological responses, including 12 of 17 (70%) patients with chronic myelomonocytic leukemia (CMML). Three of five CMML patients who failed treatment with hydroxyurea experienced major hematological responses with oral etoposide. Median response duration exceeded 9 months (range: 4-49 + months), and one patient remains in an unmaintained complete remission for 4 years. Toxicity included nausea/vomiting in five patients, fever (four patients), infection (three patients), mucositis (two patients), and anorexia (two patients). Two patients had grade 4 neutropenia with sepsis necessitating treatment withdrawal. We conclude that low-dose oral etoposide has remitting activity in MDS and is an effective treatment alternative for patients with CMML.

Isovaleric acidemia, an autosomal recessive disorder, is due to isovaleryl-coenzyme A dehydrogenase deficiency and is one of the branched-chain aminoacidopathies. Isovaleric acidemia may present in the neonatal period with an acute episode of severe metabolic acidosis, ketosis, and vomiting and may lead to coma and death in the first 2 months of life. This report concerns an infant who presented at 10 days of age because of lethargy, poor feeding, hypothermia, cholestasis, and thrombocytopenia, leukopenia, and profound pancytopenia. Death occurred at 19 days of age. Autopsy showed mild fatty change in the liver and extramedullary hematopoiesis, generalized Escherichia coli sepsis, and myelodysplasia of the bone marrow with arrest of the myeloid series at the promyelocytic stage. The appearance resembled promyelocytic leukemia, but the diagnostic 15:17 translocation was not present. The maturation arrest in granulopoiesis in isovaleric acidemia appears to be most likely due to a direct metabolic effect on granulocyte precursor cells.

To compare the antileukemic efficacy of idarubicin and mitoxantrone in elderly patients with acute myeloid leukemia (AML) and to evaluate the feasibility of autologous transplantation using PBSC after consolidation in those with a good performance status, 160 patients (median age 69 years), with AML at diagnosis, 118 of them with de novo AML and 42 with AML secondary to myelodysplastic syndrome or toxic exposure (sAML), received induction treatment with idarubicin, 8 mg/m2/day or mitoxantrone, 7 mg/m2/day, on days 1, 3, and 5, both combined with VP-16, 100 mg/m2/day on days 1 to 3 and cytarabine (araC), 100 mg/m2/day, on days 1 to 7. G-CSF, 5 microg/kg/day, was administered after chemotherapy in patients aged more than 70 years. Patients in complete remission (CR) received one course of consolidation using the same schedule as for induction except the araC administration was shortened to 5 days. Some patients younger than 70 years were then scheduled for autologous stem cell harvest on days 5 to 7 of G-CSF, 5 microg/kg/day, initiated after hematopoietic recovery from consolidation. Autologous transplantation was performed following an additional chemotherapy conditioning. Ninety-five patients (59%) achieved CR, without significant difference between the idarubicin (56% CR) and mitoxantrone (63% CR) group. There was also no significant difference in CR rate between de novo AML (63%) and secondary AML (55%) (P = 0.12). Patients aged < 70 years had 67% CR, while patients aged > or = 70 years had 49% (P = 0.02). There was no significant difference in the duration of aplasia between the two arms. Median time to neutrophil recovery was 22 days in patients who received G-CSF following induction and 27 days in patients who did not (P = 0.006). Severe extrahematologic toxicities of induction did not differ between the two arms and included sepsis (39%), diarrhea (13%), hyperbilirubinemia (8%), hemorrhage (6%) and vomiting (6%). Overall, 14 patients (9%), died from toxicity of induction. First consolidation was administered in 74 patients of whom seven (9%) died from toxicity. Nineteen patients have received transplantation. Median time to recovery of neutrophils > 0.5 x 10(9)/l was 13 days and of platelets > 50 x 10(9)/l 43 days following consolidation. There were two toxic deaths. Median disease-free survival and survival from time of achieving CR of non transplanted patients are 6 and 7 months respectively without difference between the two arms. Fourteen transplanted patients relapsed at a median of 5 months post-transplant. We conclude that this regimen is well tolerated and has a good efficacy to induce CR, without a significant difference in efficacy and toxicity between idarubicin and mitoxantrone. Intensive postinduction, including transplantation, is feasible; however, this procedure did not seem to prevent early relapse in the majority of patients. Neither the high rate of CR nor consolidation nor transplant procedure in a selected group of patients did translate into improved DFS and/or survival.

Topotecan is a topoisomerase I inhibitor with significant activity in patients with myelodysplastic syndrome and chronic myelomonocytic leukemia. Pre-clinical data suggest a synergistic activity with DNA damaging agents such as cyclophosphamide, where topotecan might prevent the repair of cyclophosphamide-induced DNA damage. We thus designed a combination including cyclophosphamide 500 mg/m2 every 12 hours given on days 1 to 3; topotecan 1.25 mg/m2/day by continuous infusion on days 2 to 6, and cytosine arabinoside (ara-C) 2 g/m2 over 4 hours daily for 5 days on days 2 to 6 (CAT). Sixty six (63 evaluable) patients were treated. Fifty two patients had refractory (n=12) or relapsed (n=40) acute myelogenous leukemia (AML), and eleven had acute lymphocytic leukemia (ALL) (refractory n=3, relapsed n=8); their median age was 57 years (range, 18 to 79 years). Eleven patients (17%) achieved a complete remission (CR), and two patients (3%) had a hematologic improvement (HI; met all criteria for CR except for platelets < 100x10(9)/L), for an overall response rate of 20%. Responses occurred in 12 of 52 AML patients (23%), including 10 CR (19%) and 2 HI (4%), and in 1 of 11 patients with ALL (9%). Myelosuppression was universal; there were 23 episodes of pneumonia or sepsis and 18 episodes of fever of unknown origin complicating 74 courses of CAT. Non-hematologic toxicity was mostly gastrointestinal, including nausea, vomiting, diarrhea and mucositis, but was severe in only 8%. In summary, the CAT regimen is well tolerated and has significant anti-leukemia activity which warrants further investigation.

Irofulven (MGI 114, 6-hydroxymethylacylfulvene, HMAF) is a semisynthetic illudin analog with broad in vitro anti-neoplastic activity. In this leukemia phase I study, we investigated the toxicity profile and activity of Irofulven in patients with primary refractory or relapsed acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), or myelodysplastic syndromes (MDS). Irofulven was given as an intravenous infusion over five minutes daily for five days. The starting dose was 10 mg/m2/day (50 mg/m2/course). Courses were scheduled to be given every 3-4 weeks according to toxicity and antileukemic efficacy. Twenty patients [AML: 17 patients; MDS: one patient; ALL: one patient; mixed lineage acute leukemia: one patient] were treated. Nausea, vomiting, hepatic dysfunction, weakness, renal dysfunction, and pulmonary edema were dose limiting toxicities, occurring in two of five patients treated at 20 mg/m2/day and two of three patients treated at 12.5 mg/m2/day. The MTD was defined as 10 mg/m2/day for five days. One patient with primary resistant AML achieved complete remission. Proposed phase II studies will further define the activity of Irofulven in patients with better prognosis AML and in other hematological malignancies, both as a single agent and in combination regimens, particularly with topoisomerase 1 inhibitors.

Antithymocyte globulin (ATG) has recently been popularized as an effective treatment in myelodysplastic syndrome (MDS). We treated 8 anemic MDS patients (refractory anemia [RA] and refractory anemia with excess blasts [RAEB-1]) with ATG (40 mg/kg/d for 4 days) and prednisone in a phase 2 trial. The study was stopped early according to a preset termination rule because of lack of efficacy. There were no salutary responses. Toxicities included serum sickness (in all patients), transient neutropenia and thrombocytopenia, diarrhea, vomiting, and syncope with a generalized seizure. At least 3 patients had the HLA-DR15 (DR2) allele. We conclude that the risk-benefit ratio of ATG in an unselected population of MDS patients may be unfavorable, and more work is needed to define the subset of patients who will respond to ATG before its widespread use can be recommended.

Two cases of scurvy diagnosed following presentation with a purpuric rash are presented. A 44-year-old man developed scurvy as a result of poor dietary intake of vitamin C. This occurred because of a number of factors. including poor dentition, diarrhoea, depression and benzodiazepine/narcotic dependence. A 69-year-old man with acute myeloid leukaemic transformation of myelodysplastic syndrome developed mucositis, nausea, vomiting and diarrhoea as complications of chemotherapy. This led to poor dietary intake and consequently scurvy. Both cases demonstrated specific and diagnostic cutaneous manifestations of scurvy, particularly perifollicular purpura, ecchymoses and coiled corkscrew hairs. The diagnosis was supported by specific diet history. Ascorbic acid tolerance test was used as a simple laboratory method to confirm the clinical diagnosis.

An 8-year-old female Shih Tzu was presented with weight loss and vomiting. Alanine aminotransferase was high and abdominal radiographs revealed hepato- and splenomegaly. Mild anaemia, neutrophilia with left shift, eosinophilia, a thrombocytosis with dysplastic features of eosinophils and platelets, were detected. The animal was initially considered to have hepatitis and was treated accordingly, but clinical signs persisted. Histological examination of liver biopsy samples showed disruption of the hepatic lobule, with extensive infiltration by haemopoietic cells. Further investigation of the bone marrow suggested a diagnosis of myelodysplastic syndrome. The animal was treated with cytarabine ocfosfate, a prodrug of cytosine arabinoside, and appeared to recover.

From 1998 to 2001, 5 consecutive cases of AML/TMDS entered our hospital and achieved complete remission (CR) with continuous drip infusion of low-dose etoposide and low-dose Ara-C combined with mitoxantrone (MEtA regimen). The ages of the 5 patients (4 males and 1 female) ranged 32 to 50 years-old, respectively. WBCs were 1,560-45,150/microl, blasts were 12-62%. Bone marrow aspirates revealed trilineage myelodysplasia with various number of blasts. These patients had an acute onset and no preceding hematologic disorders. They were diagnosed M2/TMDS or M4/TMDS. Continuous drip infusion of etoposide (50 mg/body/day) and Ara-C (30 mg/body/day) were given for 11-14 days and a bolus injection of mitoxantrone (8 mg/m2) was added for 2-3 days. Patient 5 was given additional MIT (6.7 mg/m2 on day 6). All cases achieved CR in 21-24 days after the end of the therapy. Toxicities were nausea, vomiting, stomatitis, alopecia and fever due to infection. All were well tolerable, however. Two patients are alive more than 4 years without relapse. MEtA regimen is available for AML/TMDS.

Antithymocyte globulin (ATG) is used commonly in patients with severe aplastic anemia and those undergoing renal transplant. Its utility also is being explored in the treatment of myelodysplastic syndrome, conditioning regimens for hematopoietic stem cell transplant, and prophylaxis of graft-versus-host disease. As indications for ATG expand, knowledge regarding its administration and management of associated toxicities is needed. These toxicities range from life-threatening anaphylaxis associated with the infusion to flu-like symptoms that occur one to two weeks after the infusion. Adverse effects are classified according to the severity and system impacted. Mild toxicities respond to comfort measures and include fever, chills, urticarial rash, and vomiting. Moderate toxicities require acute interventions and include fluid-responsive hypotension, nonischemic chest pain, and reversible oxygen desaturation. Severe toxicities require intensive support and include those refractory to earlier intervention. Management of these toxicities usually is limited to fluid resuscitation and noninvasive monitoring. Occurrence of infusion-related toxicities may require premature discontinuation of therapy. Therefore, an educated healthcare team and interdisciplinary clinical management guidelines are important to ensure the safe administration and complete course of ATG.
