Haploidentical haematopoietic stem cell transplantation combined with post-transplant cyclophosphamide in neuronal ceroid lipofuscinosis: Experience in eight patients.

Background: Neuronal ceroid lipofuscinoses (NCLs) are rare lysosomal storage disorders characterized by progressive mental retardation and motor developmental regression and myoclonic seizures. Hematopoietic stem cell transplantation (HSCT) has been suggested to be used in the treatment of lysosomal disorders and brain damage caused by a deficiency of soluble lysosomal enzymes. There are no previous reports on treating NCLs with HSCT in China.

Analysis of Multiple Vitamins Serum Levels and Disease-Related Factors in Children with Acute Leukemia.

Objective: To explore the relationship between vitamins levels and disease-related indicators in children with acute leukemia (AL).

Methods: A total of 107 hospitalized children with AL were enrolled in this study and assigned to one group in each of the following categories: infected group ( = 52) and noninfected group ( = 55); treatment remission group ( = 56) and nonremission group ( = 51); high-risk (HR) group ( = 44), intermediate risk (IR) group ( = 53), and slight risk (SR) group ( = 8); cyclophosphamide + cytosine arabinoside+6-mercaptopurine + pegaspargase group (CAML,  = 15); methotrexate group (MTX,  = 9); and vindesine + daunomycin + L-asparaginasum + prednisone (VALP,  = 38). Hematological and serological parameters, hepatic and renal function, and changes in vitamins A, B1, B2, B6, B9, B12, C, D, and E serum content in children with AL were analyzed to investigate their relationship with AL disease-related factors.

[Clinical Efficacy of Haplo-HSCT of ATG Combined with PTCy for Children with Myelodysplastic Syndrome].

Objective: To investigate the efficacy and safety of haploidentical hematopoietic stem cell transplantation (haplo-HSCT) in combination of ATG and post-transplant cyclophosphamide (PTCy) -induced immune tolerance after transplantation in treatment of childhood myelodysplastic syndromes(MDS）.

Methods: From July 2016 to November 2020, a total of 8 children with MDS receiving the haploidentical allo-HSCT combined with ATG and PTCy-induced immune tolerance after transplantation in our hospital were enrolled, whose clinical data were retrospected and analyzed.

Results: Median age at diagnosis of the 8 children (1 male and 7 females) was 6.

Clinical outcomes of individualized busulfan-dosing in hematopoietic stem cell transplantation in Chinese children undergoing with therapeutic drug monitoring.

To identify relationships between busulfan (Bu) exposure and outcomes of a cohort pediatric patients receiving hematopoietic stem cell transplantation (HSCT), along with a targeted busulfan-based conditioning regimen. We retrospectively evaluated targeted busulfan concentrations in 53 pediatric patients (age 0.4-16 years) who received busulfan 4 times daily according to recommended weight-based doses in a single-center analysis between 2018 and 2020.

Posttransplant cyclophosphamide for haploidentical stem cell transplantation in children with Wiskott-Aldrich syndrome.

Background: Hematopoietic stem cell transplantation (HSCT) is the curative treatment for Wiskott-Aldrich syndrome (WAS). However, it is difficult to find a matched donor for patients. Therefore, haploidentical donors should be considered for patients lacking a suitable donor.

Posttransplant Cyclophosphamide for HLA-haploidentical Transplantation in Patients With Mucopolysaccharidosis.

We successfully used a haploidentical transplantation protocol with posttransplant cyclophosphamide (CY) (50 mg/kg/d on days +3 and +4) for in vivo T-cell depletion in patients with mucopolysaccharidosis using reduced-intensive conditioning regimens, followed by a busulfan-based conditioning regimen, which included busulfan (12 to 16 mg/kg) and fludarabine(150 to 200 mg/m)+rabbit antihuman thymocyte globulin (7.5 to 10 mg/kg) as a conditioning regimen. Cyclosporine or tacrolimus, methotrexate, mycophenolate mofetil, and methylprednisolone were administered to prevent graft-versus-host disease (GVHD).
