Outcome of patients with acute myeloid leukemia (AML) who are older than 60 years of age remains unsatisfactory, with low remission rates and poor overall survival. We have previously established the activity of clofarabine plus cytarabine in AML relapse. We have now conducted a phase 2 study of clofarabine plus cytarabine in patients aged 50 years or older with previously untreated AML. Clofarabine was given at 40 mg/m2 as a 1-hour intravenous infusion for 5 days (days 2 to 6) followed 4 hours later by cytarabine at 1 g/m2/d as a 2-hour intravenous infusion for 5 days (days 1 to 5). Of 60 patients, 29 (48%) had secondary AML, 30 (50%) had abnormal karyotypes (monosomy 5 and/or 7 in 15 [25%]), and 11 (21%) showed FLT3 abnormalities. The overall response (OR) rate was 60% (52% CR, 8% CRp). Four patients (7%) died during induction. Adverse events were mainly grade 2 or lower and included diarrhea, nausea, vomiting, mucositis, skin reactions, liver test abnormalities, and infusion-related facial flushing and headaches. Myelosuppression was common. Clofarabine plus cytarabine has activity in adult AML, achieving a good CR rate. However, survival does not appear to be improved compared with other regimens. Modifications of this combination in AML therapy of older patients warrant further evaluation.

High dose of cytosine arabinoside is usually used in treatment of acute myelogenous leukemia. Here we report 1 case of a child who developed neurologic toxicity and rapidly improved after flushing out of cerebral spinal fluid, suggesting it could be treatment in the acute phase of toxicity. Efficacy of this treatment could be explained by reducing cytosine arabinoside metabolites in central nervous system.

Traditionally, patients with acute leukaemia are admitted to hospital during chemotherapy-induced pancytopenia, although a few recent reports have reported the feasibility and safety of outpatient treatment. We have developed an outpatient treatment programme for patients with acute leukaemia incorporating comprehensive patient education for self-care management at home during pancytopenia and involvement of patients in care of their tunnelled central venous catheter (CVC). During neutropenia, patients are treated with prophylactic ciprofloxacine, amoxicillin/clavulanic acid and fluconazole. Herein, we report the results of outpatient treatment of 60 patients with acute leukaemia (54 with acute myeloid leukaemia) followed prospectively in the period from March 2004 to 2007. After induction chemotherapy, outpatient treatment was possible after 48 of 73 induction courses, with no readmission in 19 of these (40%). A total of 129 consolidation courses were administered with outpatient treatment following 116 of these, with no readmission in 69 (59%). The median number of days spent at home with neutrophils below 0.5 x 10(9)/L was 8 d per course following induction and 12 d following consolidation chemotherapy. The predominant cause of readmission was neutropenic fever, in most instances of unknown origin. Coagulase-negative staphylococci and Enterococcus faecium were the most frequently identified bacteria in blood cultures, whereas only four positive blood cultures with multiresistant Escherichia coli were identified in the entire patient cohort, the latter exclusively observed in patients receiving antibiotic prophylaxis. The majority of the patients were able to take care of their CVC including change in dressing and heparin flushing. There were 12 CVC-related infections. There were no treatment-related deaths. We conclude that outpatient treatment of patients with acute leukaemia is feasible and safe.

Mastocytosis has a bimodal distribution often presenting in children from birth to 2 years of age and in those over the age of 15. Pediatric mastocytosis is due to the effects of mast-cell degranulation enzymes such as histamine and tryptase causing the presentation of pruritis, flushing, vesicles, abdominal and bone pain, or headache. Three different forms of mastocytosis can occur: urticaria pigmentosa, diffuse cutaneous, and solitary mastocytoma. Systemic symptoms are typically a result of mast-cell mediator release but do not prove systemic mast-cell hyperplasia. In this review, we present several research studies related to pediatric mast-cell disorders, and discuss several cases of pediatric mastocytosis, acute myeloid leukemia, pathophysiology, genetic studies, and treatment.
