Abstract
Herein, we describe a 13-year-old male adolescent who had chronic thrombocytopenia since infancy. In this case, X-linked thrombocytopenia (XLT) was suspected owing to a family history of chronic thrombocytopenia and small-sized platelets. Moreover, the patient was refractory to immunoglobulin therapy. The Wiskott-Aldrich syndrome protein (WASP) expression analysis revealed a decreased expression. Results showed a missense mutation [c.296A>G (p.Gln99Arg)] in exon 3 of the WASP-interacting protein region. Therefore, a diagnosis of XLT was made. To lift exercise restrictions, we initiated treatment with eltrombopag at a dose of 12.5 µg/day. The platelet count of the patient increased to approximately 50×103/µl after the treatment dose was escalated to 25 µg/day, and bleeding symptoms decreased after the patient resumed exercise. Ultrastructural platelet abnormalities and abnormal platelet aggregation were observed on transmission electron microscopy after the administration of eltrombopag. Therefore, eltrombopag treatment can increase platelet count and reduce bleeding symptoms in patients with XLT.

Abstract
BACKGROUND Fatal adverse effects or relapse can occur with excessive or insufficient busulfan exposure in hematopoietic stem cell transplantation. Given that busulfan is mainly metabolized by glutathione S-transferase (GST), we investigated the influence of GST polymorphisms on busulfan pharmacokinetics in Japanese pediatric patients. METHODS Blood samples were taken from patients receiving high-dose i.v. busulfan as the first dose. Plasma busulfan concentration was measured using high-performance liquid chromatography. The area under the plasma busulfan concentration-time curve (AUC) was calculated. The genotype of GSTA1 was determined on polymerase chain reaction (PCR)-restriction fragment length polymorphism. Multiplex PCR was used to detect the presence or absence of GSTM1 and GSTT1 in the genomic DNA samples. RESULTS Twenty patients were consecutively enrolled. Phenotype prediction was defined as follows: poor metabolizer (n = 4), one or more GSTA1*B haplotype or GSTM1/GSTT1 double-null genotypes; and extensive metabolizer (n = 16), other genotypes. GSTA1, M1, and T1 independently had no significant differences in AUC0-∞ , clearance or elimination rate constant. For the infant with unexpectedly high AUC0-∞ (2,591 μmol/L min), the GSTA1, M1, and T1 polymorphisms were wild type. On further analysis, the poor metabolizer group had lower clearance and higher AUC0-∞, except for the aforementioned patient, compared with the extensive metabolizer group (1,531 vs 1,010 μmol/L min; P < 0.01). CONCLUSIONS GST polymorphisms may have affected busulfan pharmacokinetics, but these effects were obscured by other factors, such as underlying disease, systemic conditions, treatment history, and race.

Abstract
Stenotrophomonas maltophilia causes pneumonia and CVC-CRBSI in HSCT. However, there are few reports of pyomyositis due to S. maltophilia. We report a patient with CRBSI and pyomyositis due to S. maltophilia after allogeneic HSCT who was successfully treated by removing the CVC and antibiotics without surgical drainage. Removing the CVC and the combined antibiotics without preventing the neutrophil engraftment could avoid surgical drainage in pyomyositis due to S. maltophilia when detected in an early stage.

Abstract
Optimizing systemic busulfan exposure, the area under the concentration-time curve (AUC), improves the outcomes for hematopoietic stem cell transplantation (HSCT). The AUC is conventionally calculated using six plasma concentrations (AUC(0-∞)) drawn after the first of 16 intravenous busulfan doses given as a 2-h infusion every 6 h. The aim of the present study was to develop limited sampling strategies using three or fewer busulfan concentrations to reliably calculate AUC(0-∞) in patients undergoing HSCT. We investigated the pharmacokinetics of busulfan 46 times in 29 pediatric patients receiving intravenous busulfan. Limited sampling strategies using one, two, or three plasma busulfan concentrations were developed by multiple linear regression that showed excellent agreement with AUC(0-∞). In single-point sampling strategies, the AUC(0-∞) predicted based on C(6) (trough level: busulfan plasma concentration 6 h after the start of the infusion) was significantly correlated with, and not statistically different from, actual values as follows: AUC(0-∞) = 2556.5 C6 + 320.9 (r(2) = 0.929, P < 0.0001, mean bias 0.282 %, precision 7.91 %). In contrast, the predicted AUCs derived from the other sampling single points did not meet the criteria. The trough level well correlated with actual AUC(0-∞), suggesting that this time-point is acceptable for busulfan monitoring.
