Studies of renal involvement in thalassemia syndromes have been varied and few. The most important cause of mortality and morbidity in these patients is organ failure due to iron deposition. We report here a cross-sectional study carried out between February 2005 and February 2006 on all beta-thalassemia major patients being treated in Mofid Children’s(More)
Immunodeficiency and autoimmune disease may occur concomitantly in the same individual. Some of the immunodeficiency syndromes, especially humoral defects are associated with autoimmune disorders. Hematological manifestations such as thrombocytopenia and hemolytic anemia are the most common presentations. Persistent antigen stimulation due to an inherent(More)
PURPOSE This study aimed to evaluate iron levels in cardiac and hepatic tissues using magnetic resonance imaging (MRI) T2*. METHODS Cardiac and hepatic MRI was performed for 93 patients with β-thalassemia major. RESULTS Cardiac T2* was in the range of 2.9-56.6 ms. Myocardial siderosis was detected in 44% of patients; 25 patients had moderate and severe(More)
BACKGROUND Although a marked proportion of thalassemic patients acquire Torque teno virus (TTV) through blood transfusion, its clinical importance is unclear. This study was designed to investigate the clinical importance of TTV infection in thalassemic patients with and without hepatitis C virus (HCV) co-infection in Iran. METHODS In this case-control(More)
Hemophagocytic lymphohistiocytosis (HLH) is a rare condition characterized by fever, hepatosplenomegaly, and cytopenia, and widespread accumulation of lymphocytes and histiocytes, sometimes with hemophagocytosis, primarily involving the spleen, lymph nodes, bone marrow, and liver. HLH can either occur sporadically (secondary HLH) or as part of a familial(More)
Griscelli syndrome type 2 is a rare autosomal recessive primary immunodeficiency disease caused by a mutation in the RAB27A gene and characterized by oculocutaneous hypopigmentation and variable cellular immunodeficiency. We report the case of a 6-month-old infant with silvery hair, eyelashes, and eyebrows who was referred to our center because of fever and(More)
Congenital atransferrinemia or hypotransferrinemia is a very rare autosomal recessive disorder, characterized by a deficiency of transferrin, resulting in hypochromic, microcytic anemia and hemosiderosis. The authors describe a 10-year-old Iranian girl with hypochromic microcytic anemia. The age presentation of anemia was 3 months. Further evaluations(More)
The primary intrarenal neuroblastoma (IRNB) is a rare condition. Intrarenal neuroblastoma typically results from direct renal invasion from an adrenal neuroblastoma, but true intrarenal neuroblastoma originates either sequestered adrenal rests during the fetal life or intrarenal sympathetic ganglia. Clinical, radiological, and pathological correlation is(More)
INTRODUCTION Histological typing, especially the evidence of anaplasia and stage of the tumor are two major prognostic indicators in Wilms tumor, but some genetic factors have recently been noted. Mutations in TP53, which is a tumor suppressor gene, have been demonstrated to be associated with poor prognosis in some malignancies. There are also few studies(More)
Severe congenital neutropenia (SCN) is a rare primary immunodeficiency disease. Different genes are found to be associated with SCN, including ELA2, HAX1, WAS, GFI1, G-CSFR and G6PC3. The aim of this study was to find different gene mutations responsible for SCN in Iranian patients. Twenty-seven patients with SCN referred to Immunology, Asthma and Allergy(More)
