Background There is no consensus on the optimal dosage use of posaconazole (PSC) for invasive fungal infection (IFI) in pediatric patients and normally it is adjusted with drug levels (DLs) ≥ 0.7 μg/ml and ≥ 1.25 μg/ml for prophylaxis and treatment, respectively. Objective To describe the experience of monitoring DLs of PSC in immunocompromised pediatric patients with IFI and to determine if the recommended doses reach CP effective in prophylaxis (≥ 0.7 μg/mL) and treatment (≥ 1.25 μg/mL). Method A retrospective analysis in children who received PSC from January 2012 to October 2016, in the Oncology and Bone Marrow Transplant units at Hospital Calvo Mackenna was done Six patients with 78 DLs were reviewed (4 prophylaxis and 4 treatment)...

Microsporidiosis is a rare, but emerging opportunistic infection in solid organ transplant and stem cell transplant recipients. Renal involvement in microsporidiosis is very rarely seen in these recipients. We describe two cases of pediatric renal microsporidiosis, diagnosed on renal biopsies, following bone marrow transplantation presenting as severe acute kidney injury. The first patient died, whereas the second survived due to early diagnosis based on high index of suspicion and prompt treatment with Albendazole...

PURPOSE: Children with advanced cancer are often not referred to palliative or hospice care before they die or are only referred close to the child's death. The goals of the current project were to learn about pediatric oncology team members' perspectives on palliative care, to collaborate with team members to modify and tailor three separate interdisciplinary team-based interventions regarding initiating palliative care, and to assess the feasibility of this collaborative approach. METHODS: We used a modified version of experience-based codesign (EBCD) involving members of the pediatric palliative care team and three interdisciplinary pediatric oncology teams (Bone Marrow Transplant, Neuro-Oncology, and Solid Tumor) to review and tailor materials for three team-based interventions...

Invasive fungal infections (IFIs) are a major cause of infection-related morbidity and mortality in patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT). Data from pediatric settings are scarce. To determine the incidence, risk factors and outcomes of IFIs in a 180-day period post-transplantation, 408 pediatric patients who underwent allogeneic HSCT were retrospectively analyzed. The study included only proven and probable IFIs. The cumulative incidences of IFI were 2.7%, 5.0%, and 6...

BACKGROUND: The combination of cyclophosphamide (CY) and antithymocyte globulin (ATG) has been used as a standard conditioning regimen for matched related donor transplantation in patients with severe aplastic anemia. PROCEDURE: To decrease the regimen-related toxicity while maintaining appropriate engraftment and survival rates, fludarabine (FLU) was added to the regimen. Four pediatric patients received matched related donor bone marrow transplantation with CY (50 mg/kg×2) (instead of the 50 mg/kg×4 standard dosing), equine ATG (30 mg/kg×3), with the addition of FLU (30 mg/m×4)...

A 9-year-old girl was referred to our hospital because of facial palsy. Both physical and blood examination revealed hepatosplenomegaly and leukocytosis, respectively. A bone marrow examination demonstrated marked hypercellularity involving myeloblasts and lymphoblasts. Based on these results, we suspected mixed phenotype acute leukemia. However, her leukemic blasts expressed B-cell antigens, and a chromosomal analysis of her bone marrow cells revealed the following karyotype: 46, XX, t (9;22) (q34;q11.2). All her neutrophils were positive for the breakpoint cluster region-Abelson murine leukemia viral oncogene homolog 1 fusion protein...

RATIONALE: Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease entity primarily described in children, but not less relevant in adults. It is characterized by a misdirected activation of the immune system, resulting in an uncontrolled cytokine release from macrophages and cytotoxic T-cells (CTLs). Primary HLH relies on a genetic predisposition, whereas secondary HLH develops in the context of infections, malignancies or autoimmune diseases. However, the awareness and therapeutic knowledge for HLH in adulthood is limited...

Human T-cell lymphotropic virus (HTLV), an infection that is endemic in certain parts of Asia, Africa, and South America, has been associated with malignancy and neurological deficits. Here, we describe a pediatric patient with chronic HTLV-I infection who developed complications associated with HTLV-I (ie, adult T-cell leukemia/lymphoma and HTLV-I-associated myelopathy/tropical spastic paraparesis). To our knowledge, this presentation in a child has never been described. The patient underwent a bone marrow transplant and, at the time of this writing, was in remission...

BACKGROUND: Celiac disease may present with hematological abnormalities including long-standing anemia. Both aplastic anemia and celiac disease have a similar underlying autoimmune process but an association between the two is seldom reported. There have only been three pediatric cases reporting this association and this case is the first reported in a female pediatric patient. CASE PRESENTATION: We report a case of 6-year-old South Asian girl presenting with bruises, petechiae, and recent history of loose stools...

Renal lymphoma is an uncommon renal tumor in children. Unlike renal lymphomas presenting as bilateral disease and renal failure, we report a boy who presented with unilateral renal involvement. After initial nephrectomy, he achieved remission with multiagent chemotherapy but relapsed systemically within 3 months. He was initiated on salvage chemotherapy with autologous bone marrow transplant. Even though the initial manifestation was localized lymphoma eventually, it turned out to be a systemic disease. He succumbed to disease at 14 months from diagnosis...

The treatment of leukemia/lymphoma by chimeric antigen receptor (CAR) redirected T cells with specificity for CD19 induced complete remissions in the majority of patients, with a realistic hope for cure. However, recent follow-up data revealed a substantial risk of relapse through leukemic cells that lack the CAR targeted antigen. In this situation, a bispecific CAR with binding domains for CD19 and CD20 is aimed at recognizing leukemic cells with only one cognate antigen. The anti-CD20-CD19 bispecific CAR induced a full T-cell response upon engagement of CD19 or CD20 on target cells showing a true "OR" gate recognition in redirecting T-cell activation...

Hemorrhagic cystitis is one of the complications of allogeneic hematopoietic stem cell transplantation. Treatment of hemorrhagic cystitis is difficult, especially in pediatric patients. A pediatric case of severe hemorrhagic cystitis after hematopoietic stem cell transplantation was treated in our hospital with arterial embolization combined with corticosteroid therapy because the conventional therapy was invalid for him. After the treatment, hemorrhagic cystitis was cured. During follow-up, the patient was in stable condition, with normal urine, blood cells returned to normal, bone marrow was in complete remission state, and disease-free survival for more than 8 months...
