BACKGROUND: Busulfan is commonly used as a conditioning regimen before hematological stem cell transplantation (HSCT). There is a big inter-individual variability in busulfan exposure and the narrow therapeutic index, especially in pediatric population. Therefore, to achieve therapeutic efficacy and safety concurrently, personalized busulfan dosing, guided by pharmacokinetic study with serial plasma samples, is needed a few hours afterwards. METHODS: We used liquid-chromatography-mass spectrometry (HPLC-MS/MS) to develop, validate, and implementation of a fast, sensitive, and accurate method for busulfan measurement...

Growing evidence indicates that aberrant DNA hypermethylation is associated with leukemogenesis, chemotherapy resistance, and relapse. DNA methyltransferase inhibitors such as azacitidine and decitabine have been shown to reverse drug resistance and prime leukemia cells to cytotoxic agents in vitro. Here we report the first pediatric phase 1 study using azacitidine in sequence with chemotherapy in patients with relapsed/refractory leukemia. Fourteen patients were enrolled, twelve with acute myeloid leukemia (AML) and two with acute lymphoblastic leukemia (ALL)...

Social media are powerful means of communication that can also have an important role in the healthcare sector. They are sometimes seen with diffidence in the healthcare setting, partly because they risk blurring professional boundaries. This issue is particularly relevant to relations between caregivers and adolescent patients. The Italian Pediatric Hematology and Oncology Association created a multidisciplinary working group to develop some shared recommendations on this issue. After reviewing the literature, the working group prepared a consensus statement in an effort to suggest an analytical approach rather than restrictive rules...

Continuous intravenous (IV) infusion has been shown to be the best option to administer vancomycin because of its time-dependent bactericidal activity. Available IV vancomycin dosing guidelines in pediatrics with normal renal function leads to less than 50% of patients achieving a vancomycin serum concentration (Css) in the target range (15 to 20 mg/l). The primary objective of this study was to prospectively validate an age-based dosing regimen in pediatric onco-hematology. The secondary objective was to investigate the influence on Css attainment of different variables...

Preclinical and clinical development of agents that inhibit cell-cycle progression have brought an understanding of the feasibility of targeting various cell-cycle regulators in patients with cancer. Small molecule inhibitors targeting key proteins that participate in cell-cycle progression including the cyclin-dependent kinases and checkpoint kinases induce cell-cycle arrest and apoptosis in neoplastic cells. Early phase I studies demonstrate targeted inhibitors can be administered safely in adult and pediatric cancer patients, but these agents generally show limited clinical benefits as single agents...

As a consequence of acquired or intrinsic disease resistance, the prognosis for patients with relapsed or refractory T-cell acute lymphoblastic leukemia (T-ALL) is dismal. Novel, less toxic drugs are clearly needed. One of the most promising emerging therapeutic strategies for cancer treatment is targeted immunotherapy. Immune therapies have improved outcomes for patients with other hematologic malignancies including B-ALL, however no immune therapy has been successfully developed for T-ALL. We hypothesize targeting CD38 will be effective against T-ALL...

Blood hemoglobin (Hb) is a common indicator for diagnosing anemia and is often determined through laboratory analysis of venous samples. One alternative to laboratory-based methods is the handheld HemoCue® Hb 201+ device, which requires a finger prick and wicking of blood into a pretreated cuvette for analysis. An alternative HemoCue® gravity method is being investigated for improved accuracy. Further, recent developments in noninvasive technologies could provide an accurate, rapid, safe, point-of-care option for hemoglobin estimation while addressing some limitations of current tools, but device performance must be assessed in low-resource settings...

Splenic hamartoma (or splenoma) is a rare, benign, vascular tumor, often incidentally found at imaging, surgery or autopsy. Albeit usually asymptomatic and rare in children, when it occurs in the pediatric population it is more commonly symptomatic. We report a case of a 15-year-old girl with iron-deficiency anemia and beta-thalassemia, who had a large (10 × 8 × 7 cm) splenic lesion with calcifications, incidentally found during follow-up for splenomegaly and histologically characterized as hamartoma with calcified areas...

The rapid spread of severe infections mainly due to resistant pathogens, justifies the search for therapies aiming to restore immune functions severely compromised in patients with hematologic malignancies. Areas covered: The present review summarizes the current knowledge on the role of granulocyte transfusions and colony-stimulating factors as treatment strategy for hematologic patients with serious infectious complications. In addition, a survey among 21 hematologic centers, to evaluate the clinical practice for the use of G-CSF originator and biosimilars was performed...
