the restriction enzyme ava ii detects the base change of the intervening sequence ii (ivs ii) which is used as one of the markers of β-globin gene polymorphism. this study was conducted to determine the frequency of the ava ii site on the β-globin gene among normal people and patients with sickle cell syndrome (scs) in iran. dna fragments containing the ivs ii region of the β-globin gene from 3...

Coronavirus Disease 2019 (COVID-19) is a significant medical and public health problem in the world. It is believed that it can worsen in extreme conditions. Also, it is suggested that blood disorders such as sickle cell disease (SCD) may increase the risk of COVID-19 symptoms. The present study reports a family facing COVID-19, in which one of two members with SCD presented with fever, repeate...

results sickle cells were observed among 20% of subjects with the dilution of 1:50 and 70% of subjects with the dilution of 1:100. mean percentage of sickle red cells with dilutions of 1:50, 1:100 and 1:200 were 3.75%, 25.75% and 43.0%, respectively. conclusions it is suggested that c. fistula may protect rbc against sickling, in hypoxic conditions, in individuals with hbs gene defect. objectiv...

Background: There are many parameters that modulate the severity of sickle cell anemia. Fetal hemoglobin (Hb F) is one of these major variables. However, its effect is clinically inconsistent. We conducted a descriptive study to assess the influence of Hb F on clinical events and hematological variables in patients with sickle cell anemia. Methods: 151 patients with sickle cell anemia with a st...

Abstract Background Prevalence of hereditary blood diseases such as sickle cell anemia, sickle thalassemia and thalassemia major are high in Khuzestan province. Sickle cell anemia and beta-thalassemia are predominantly common in Iranian Arabs. Pulmonary complications account for a large proportion of morbidity and mortality in patients with and sickle cell disease. Periodic lung function asse...

A young adult with homozygous sickle cell anaemia (Hb SS) suffered a fatal sickle cell crisis complicated by the sickle chest syndrome. At necropsy multiple large infarcts of the lung, bone marrow, and pituitary gland were found. The large majority of pulmonary infarcts were not associated with either gross or microscopic vaso-occlusion. These findings are discussed and correlated with past and...
