Results All had received unrelated donor transplant. Six...
Abstract Background: Despite the introduction of a polymerase chain reaction (PCR) test for diagnosis respiratory viral infection (RVI), guidance on application this and management RVI in immunocompromised children is lacking. This study evaluated clinical characteristics established strategies PCR adolescents with hematological malignancies.Methods: included underlying malignancies symptoms, whom multiplex was performed. Patients identified not were categorized into Groups I II,...
ETV6/RUNX1 (+) acute lymphoblastic leukemia (ALL), which is the most common genetic subtype of pediatric ALL, has a favorable prognosis. In this study, we analyzed outcome ALL patients treated at our institution with aim identifying significant prognostic variables.Sixty-three were diagnosed from 2005 to 2011. Prognostic variables studied included minimal residual disease (MRD) as detected by fusion, and presence additional cytogenetic abnormalities.The 5-year event-free survival was...
Although intravenous acyclovir therapy is recommended for varicella zoster virus (VZV) infection in immunocompromised children, the clinical characteristics and outcomes of VZV era have rarely been reported.The medical records children diagnosed with or herpes virus, who had underlying hematologic malignancies, were retrospectively reviewed, evaluated.Seventy-six episodes (herpes 57 19) identified 73 children. The median age was 11 years (range, 1-17), 35 (46.1%) occurred boys. Acute...
We conducted a retrospective study on 51 pediatric patients with newly diagnosed chronic myeloid leukemia phase or accelerated phase. The were classified into the IMA group (N = 33), treated imatinib, and DSA 18), dasatinib, as front-line tyrosine kinase inhibitors (TKIs). At 12 months, rates of complete cytogenetic response similar between (92.3%) (100%) (p 0.305). However, rate early molecular was higher in than (100.0% vs. 80.0%, p 0.043). By 24 showed faster cumulative both major (DSA...
Background: Acute myeloid leukemia with the t(8;21)(q22;q22) rearrangement ( RUNX1-RUNX1T1 (+) AML) is known to have a favorable prognosis. Our study aimed determine most important prognostic variables among an aggregate of clinical, genetic, and treatment response-based factors in pediatric AML. Materials Methods: We analyzed characteristics outcome 40 patients who were diagnosed treated for AML from April 2008 December 2016 at our institution. Results: A<−2.2 log fusion transcript...
Whether plasma MTX concentrations and MTHFR C677T A1298C polymorphisms could be used as a predictor of occurrence MTX-related toxicities in Korean paediatric patients with acute lymphoblastic leukaemia (ALL) were assessed. HD-MTX related toxicities, following 337 cycles to 117 children ALL on maintenance therapy analyzed. A significantly higher frequency hyperbilirubinemia (P = 0.0443) renal toxicity 0.0107) associated high by Fisher's exact test. Moreover, at 24 h, 48, 72 h increased...
Purpose: This study aimed to investigate the clinical factors associated with bone mineral density (BMD) among children and adolescents osteoporosis secondary treatment for underlying conditions.Methods: We retrospectively reviewed medical records of patients aged 10–18 years evaluated them lumbar spine BMD (LSBMD) after diseases, including hemato-oncologic, rheumatologic system, inflammator y bowel diseases. LSBMD measured by dual-energy x-ray absorptiometry (DXA) performed from March 2019...
Lifelong treatment of pediatric chronic myeloid leukemia (CML) patients with tyrosine kinase inhibitors (TKIs) can affect their growth and development. For these reasons, clinical trials have explored the feasibility TKI discontinuation in children a sufficient response. We evaluated analytical performance digital droplet PCR (ddPCR) to quantify BCR-ABL1 compared results reverse transcription quantitative polymerase chain reaction (RT-qPCR). further investigated whether ddPCR could be used...
Although acyclovir prophylaxis against varicella zoster virus (VZV) infection for ≥1 year is recommended after allogeneic hematopoietic cell transplantation (HCT), the emergence of acyclovir-resistant viruses and adverse drug effects cannot be ignored. We investigated cumulative incidence VZV HCT in children receiving a shorter duration than evaluated appropriateness short prophylaxis. Medical records 217 who received were retrospectively reviewed until median 25 months (range = 1–59 months)...
