Tartrate-Resistant Acid Phosphatase 5b in Young Patients With Sickle Cell Disease and Trait Siblings: Relation to Vasculopathy and Bone Mineral Density.

Bone involvement is a frequent cause of acute morbidity in sickle cell disease (SCD). Tartrate-resistant acid phosphatase 5b (TRACP 5b), a bone resorption marker, is produced specifically by activated osteoclasts. We assessed bone mineral density (BMD) in 30 young patients with SCD and 17 asymptomatic patients with sickle cell trait (SCT) compared with 32 healthy controls and determined TRACP 5b levels in relation to vascular complications.

Clinical to Molecular Screening Paradigm for β-Thalassemia Carriers.

β-Thalassemia (β-thal) represents a major health problem worldwide and particularly in Egypt. Its prevention, compared to treatment, is cost-effective, possible and practical. In this study we evaluate a proposed paradigm for detection of the β-thal carrier state.

Alterations of platelet functions in children and adolescents with iron-deficiency anemia and response to therapy.

Several changes in platelets have been reported in patients with iron-deficiency anemia (IDA), so a relationship between iron metabolism and thrombopoiesis should be considered. We aimed to study the alterations of platelet functions in patients with IDA by assessment of platelet aggregation with epinephrine, adenosine diphosphate (ADP) and ristocetin and by measuring platelet function analyzer-100 (PFA-100) closure time together with the effect of iron therapy on the same tests. A follow-up study was conducted in Ain Shams University Children's hospital in the period from June 2011 to June 2012 including 20 patients with confirmed IDA and 20 healthy age- and sex-matched control.

Health-related quality of life of Egyptian children with immune thrombocytopenia and their parents.

Health-related quality of life has been recognized as an important pediatric outcome measurement. Kid's ITP Tool was used to measure health-related quality of life of 80 Egyptian children with immune thrombocytopenia and their parents in relation to different disease parameters. A positive correlation between scores of child/proxy reports and parent report was found.

Morbidities and mortality in transfusion-dependent Beta-thalassemia patients (single-center experience).

Background: The improvement of quality and duration of life of transfusion-dependent B thalassemia patients over the last years discloses several complications due to the underling disorder, iron overload and the treatment with iron chelators. Our Aim was to assess the morbidity patterns and mortality rate of transfusion-dependent thalassemia patients, and compare the outcomes in relation to age of onset, type, duration, and compliance to iron chelation therapy and frequency of blood transfusion.

Procedure: This retrospective study included 447 transfusion-dependent β-thalassemia patients who attended the Thalassemia Center, Ain Shams University Children's Hospital over the last 10 years in the period between January 2000 and January 2010.

A longitudinal prospective study of bleeding diathesis in Egyptian pediatric patients: single-center experience.

Keeping an updated registry of bleeding disorders is crucial for planning care and documenting prevalence. We aimed to assess the prevalence of various bleeding disorders including rare inherited coagulation and platelet disorders concerning their clinico-epidemiological, diagnostic data and bleeding manifestations severity. Patients suffering from manifestations of bleeding or coagulation disorders presented to Hematology Clinic during 16 years were included and prospectively followed up.

Romiplostim therapy in children with unresponsive chronic immune thrombocytopenia.

Romiplostim, a thrombopoiesis-stimulating peptibody, represents a new therapeutic option in adult refractory chronic immune thrombocytopenia (ITP). This study aimed to assess the short-term efficacy and safety of romiplostim in children with chronic ITP. Eight non-splenectomized patients with chronic ITP refractory to standard lines of medical therapy were recruited from the Pediatric Hematology Unit, Children's Hospital, Ain Shams University, Cairo, Egypt.
