abstract

abstract background multiple transfusions in thalassemia patients may lead to antibody production against blood group antigens and hemolytic transfusion reaction might occur. in this study, antibody screening test was performed by tube and gel methods to determine the prevalence and specificity of alloantibodies in thalassemia patients. materials and methods in this cross-sectional study, overall of 100 thalassemia patients from yazd thalassemia clinic were recruited from july to september 2013. two blood samples with volume of 6 ml were collected from each patient for standard tube and gel method antibody screening tests and a questionnaire consisting of demographic, health and blood transfusion status was completed. results out of 100 cases, 54 were female (54%) and 46 male (46%). the patients' age mean was 14.97±7.91 years with 2 to 33 years age range. only 4% (n=4) had developed alloantibodies. (one patient developed dual alloantibody (anti-c and anti-d) and three patients developed single alloantibody (anti-k)).gel method detected 4 patients with alloantibody but in two patients not detected by the standard tube method. conclusion the prevalence of rbc alloantibody production in this study was less than most previous studies. anti-k was the most prevalent alloantibody in thalassemia patients in yazd. it seems rh and kell blood group phenotyping in a newly diagnosed thalassemia patient and selection of matched blood for transfusion is very important.

Prevalence of Alloantibodies and Autoantibodies in Transfusion Dependent Thalassemia Patients

Background: The development of anti-red blood cell alloantibodies remains a major problem in transfusion of blood in thalassemia major patients. Also, Autoantibodies can result in clinical hemolysis and difficulty in cross-matching blood. We studied the frequency of red blood cell alloimmunization and autoimmunization among thalassemia patients who received regular transfusions in Ilam province...

Molecular Spectrum of Beta-Globin Mutations in Transfusion-Dependent Patients with Thalassemia in Qazvin Province, Iran

Background: Beta thalassemia is a common inherited disease, resulting from one or more of 200 different mutations in the beta-globin gene. Qazvin province has attracted migrations of several different populations due to industrialization during the past five decades. The aim of this study was to define the molecular spectrum of beta-thalassemia mutations in Qazvin province. Methods: Ethylen dia...

Prevalence of Diabetes Mellitus in Patients with Transfusion Dependent β Thalassemia

Introduction: Thalassemia is common in Iran. Appropriate therapy for this disease includes a regular blood transfusion and chelation therapy. However, patients will inevitably confront with side effects, particularly iron overloads in critical organ including heart, ductless glands and liver. This study tries to determine the prevalence of diabetes mellitus in transfusion dependent β thalassemi...
