With the optimization of transfusional and chelation regimens, beta-thalassemia has changed from a pediatric disease with poor life expectancy into a chronic disease. Bone demineralization is an important cause of morbidity in older patients; the etiology is multifactorial and partially unknown. We examined, cross-sectionally, 111 adult patients with(More)
Despite evidence of considerable iron overload in transfusion-independent patients with β-thalassemia intermedia, data on hepatic outcomes remain scarce. We analyzed data from a cohort of 42 β-thalassemia intermedia adults followed for four years (median age 38years), and evaluated the association between longitudinal changes in serum ferritin levels and(More)
PURPOSE To determine the prevalence and spectrum of ocular fundus abnormalities in patients with β-thalassemia and to investigate risk factors for their development. DESIGN Cross-sectional, observational study. PARTICIPANTS A total of 255 patients with β-thalassemia major (TM) and β-thalassemia intermedia (TI) were consecutively recruited and(More)
BACKGROUND The mechanisms responsible for the increased thrombotic risk associated with thalassemia are still unclear. They might be related to the effects of red blood cell or endothelial cell derangements, increased numbers of platelets as well as abnormal plasma coagulation. DESIGN AND METHODS To evaluate the relative role played by cells and plasma we(More)
Due to the increasing survival of thalassemic patients, osteopathy is a mounting clinical problem. Low bone mass alone cannot account for the high fracture risk described; impaired bone quality has been speculated but so far it cannot be demonstrated noninvasively. We studied bone quality in thalassemia major using trabecular bone score (TBS), a novel(More)
OBJECTIVE Data about endocrine and bone disease in nontransfusion-dependent thalassaemia (NTDT) is scanty. The aim of our study was to evaluate these complications in β-TI adult patients. METHODS We studied retrospectively 70 β-TI patients with mean followup of 20 years. Data recorded included age, gender, haemoglobin and ferritin levels, biochemical and(More)
BACKGROUND The reproductive and sexual health issues concerning persons affected by thalassemia major are complex. The study was planned to investigate the psychological attitudes and expectations in a group of thalassemic pregnant women attending hospital for regular blood transfusion. METHODS This is a preliminary cross-sectional study involving 20(More)
Although pulmonary function abnormalities in thalassaemia major (TM) were described in 1980, the pathogenetic mechanism is not clear and data are contradictory, probably because of study heterogeneity and the multifactorial nature of the pathogenesis. We retrospectively analysed 73 adult TM patients to evaluate the prevalence of pulmonary dysfunction in(More)
As the life expectancy of β-thalassemia patients has markedly improved over the last decade, several new complications are being recognized. The presence of a high incidence of thromboembolic events, mainly in thalassemia intermedia patients, has led to the identification of a hypercoagulable state in thalassemia. In this review, the molecular and cellular(More)
A substantial proportion of patients with transfusion-dependent beta-thalassemia major suffer from chronic liver disease. Iron overload resulting from repeated transfusions and HCV infection has been implicated in the development of liver fibrosis. Hepatic siderosis and fibrosis were assessed in 99 transfusion-dependent thalassemia (TDT) patients using(More)
