We describe a 10-year-old severe hemophilia B boy with stop codon mutation of exon 2 in the factor IX gene who developed high inhibitor 70 Bethesda units (BU) from 12 months age after exposure to prothrombin complex concentrate for 14 days. The spontaneously disappeared within 3 months. patient, however, exhibited anaphylactic reaction administration and at ages 15 23 months, respectively. Although recombinant activated VII was alternatively given, he suffered progressive hemophilic...

Hemoglobin (Hb) H is generally recognized as mild thalassemia, despite its actual phenotypic diversity. A disease severity scoring system to guide initiation of regular transfusion among severely affected pediatric patients has not previously been reported.Patients with HbH were classified into transfusion-dependent thalassemia (TDT) and non-transfusion-dependent (NTDT) a surrogate for severity. Alpha-globin genotypes relevant clinical parameters associated TDT identified. Univariate...

Abstract Background Reticulocyte hemoglobin equivalent (Ret‐He), a direct measure of the (Hb) in young red blood cells, has been reported to be useful diagnosis iron deficiency anemia ( IDA ) but may have some limitations thalassemia trait. This study evaluated differences Ret‐He school‐aged children, and assessed diagnostic value identifying thalassemia‐prevalent area. Methods Blood samples underwent complete count analysis, including Ret‐He, ferritin, serum total binding capacity. also Hb...

Background Haemophilia is a lifelong X‐linked recessive inherited bleeding disorder. Since the haemophilia management in economically less‐developed countries inadequately provided, prevention of new cases essentially required. Subjects and methods A total 42 pregnancies 37 women at risk for severe moderate (A = 33, B 4) were enrolled. The prenatal diagnostic ( PND ) procedure was performed 32 women, while 10 refused further after knowing their foetuses female n 8) male 2). foetal specimen...
