Outcomes of Hematopoietic Stem Cell Transplantation in Patients With Thalassemia Major: How Do Anti-HLA Antibodies Impact?: The Impact of Anti-HLA Antibodies on Transplantation Outcomes in Thalassemia Major.

Aim: To investigate the effects of anti-human Leucocyte Antigen (HLA) antibody positivity on early hematopoietic stem cell transplantation (HSCT) results in patients with thalassemia major (TM).

Methods: One hundred and twenty-four HLA-matched HSCTs were performed in patients with TM between 2015 and 2022. Ninety-one patients were screened for anti-HLA antibodies by testing panel reactive antigens (PRA).

Restrictive effects of thalassemia on respiratory functions: One center experience.

Objective: Respiratory functions in thalassemia major (TM) patients concerning poor chelation are a frequently researched issue. Our study aims to evaluate the lung functions of our patients with TM in the chronic transfusion program and to correlate them with their age, ferritin levels, and pre-transfusion hemoglobin values.

Methods: Height, weight, pulmonary function test (PFT) results, pre-transfusion hemoglobin levels, and ferritin levels of 97 patients (55 boys and 42 girls) without any underlying cardiac or chronic respiratory disease were recorded.

Hemophilia Caregiver Burden in a Low Socioeconomic Region of Turkey.

Objective: This study aims to evaluate the caregiver burden of parents of hemophilia patients and related factors in the southeast region of Turkey, where access to a regular healthcare facility is more complicated than in other areas.

Materials And Methods: Twenty-six caregivers of patients with hemophilia were consecutively enrolled in this non-interventional study. Caregiver burden is measured using the "HemophiliaAssociated Caregiver Burden Scale" (HEMOCAB).

The impact of Treosulfan-based conditioning for inborn errors of immunity: Is dose monitoring crucial?

Introduction: In children with inborn errors of immunity (IEI) who will receive a hematopoietic stem cell transplant (HSCT) treosulfan-based conditioning is currently preferred. The aim of this study was to investigate early and late outcomes in pediatric IEI patients receiving pre-HSCT treosulfan and to examine the effect of treosulfan dose monitoring on outcomes.

Methods: Seventy-three pediatric patients receiving this management between 2015 and 2022 were included.

Primary immunodeficiencies: HSCT experiences of a single center in Turkey.

Background: Primary immunodeficiency diseases (PID) are characterized by the occurrence of frequent infections and are caused by many genetic defects. Hematopoietic stem cell transplantation (HSCT) is the only curative treatment option for the majority of PID. As a Pediatric Hematology-Oncology-Immunology Transplantation Unit, we wanted to present our HSCT experience regarding treatment of primary immunodeficiency diseases.

Posterior Reversible Encephalopathy Syndrome in Childhood Hematological/Oncological Diseases: Multicenter Results.

The aim of the study was to analyze the characteristics of posterior reversible encephalopathy syndrome (PRES) cases treated at 10 different institutions in our country. Fifty-eight patients diagnosed with PRES were included in this study. The data of PRES cases from 10 departments of pediatric hematology/oncology were analyzed.

Hepatosplenic Fungal Infections in Children With Leukemia-Risk Factors and Outcome: A Multicentric Study.

Background: Invasive fungal infections, including hepatosplenic fungal infections (HSFI), cause significant morbidity and mortality in children with leukemia. There are not enough data to support for the best approach to diagnosis of HSFI in children, nor for the best treatment.

Procedure: In this multicentric study, we assessed the demographic data, clinical and radiologic features, treatment, and outcome of 40 children with leukemia and HSFI from 12 centers.

Thrombosis in children: Which test to whom, when and how much necessary?

Pediatric thrombosis is multifactorial, and usually risk factors either congenital or acquired are present. After 2000, systematic reviews and meta-analysis on pediatric venous thromboembolic disease and inherited thrombophilia revealed elevated thrombotic risks in these children. In this review, we discuss thrombosis and new literature in various pediatric patient groups and the usefulness of thrombophilia testing.

Homozygous protein C deficiency presenting as neonatal purpura fulminans: management with fresh frozen plasma, low molecular weight heparin and protein C concentrate.

Purpura fulminans in neonates is a rapidly progressive thrombotic disorder manifesting as hemorrhagic skin infarction and disseminated intravascular coagulation. Being inherited in an autosomal dominant manner, it is a medical emergency. Clinical presentations of patients may vary depending on the genetic mutations.

Treatment of plasminogen deficiency patients with fresh frozen plasma.

Congenital plasminogen (Plg) deficiency leads to the development of ligneous membranes on mucosal surfaces. Here, we report our experience with local and intravenous fresh frozen plasma (FFP). We retrospectively reviewed medical files of 17 patients and their eight first-degree relatives.

Sinusoidal Obstruction Syndrome During Chemotherapy of Pediatric Cancers and its Successful Management With Defibrotide.

Sinusoidal obstruction syndrome (SOS) is a life-threatening complication generally occurring after hematopoietic stem cell transplantation. SOS after standard dose chemotherapy in malignancies is rare. Between the year 1995 and 2016, 414 patients were diagnosed with acute lymphoblastic leukemia and 113 patients were diagnosed with Wilms tumor in our institution.
