A multicenter cross-sectional study of the quality of life and iron chelation treatment satisfaction of patients with transfusion-dependent ß-thalassemia, in routine care settings in Western Greece.

PURPOSE: To evaluate health-related quality of life (HRQoL) and satisfaction with iron chelation therapy (ICT) of patients with transfusion-dependent ß-thalassemia (TDT) managed under routine care conditions. PATIENTS AND METHODS: This was an observational, multicenter, cross-sectional study conducted in three hospital-based Thalassemia Units of Western Greece. Patients confidentially completed the 36-item short-form (SF-36) and the "satisfaction with ICT" (SICT) instruments to assess HRQoL and ICT satisfaction respectively. RESULTS: One hundred and thirty-one adult TDT patients [74 female, median (IQR) age: 41 (36-47) years] were enrolled. Eighty patients (61.1%) were receiving parenteral ICT, with or without oral chelators (Group I), whereas 51 (38.9%) were only receiving oral ICT (Group II). The median SF-36 physical component summary and mental component summary scores were 76.3 and 75.7 among Group I, and 76.9 and 74.5 among Group II patients, not differing between the two groups. In their majority, Group I (84.6%) and Group II (92.9%) patients reported preferring oral ICT. Moreover, Group I patients reported greater perceived ICT effectiveness (median SICT score: 4.3 versus 4.2; p = 0.039), whereas patients receiving deferasirox-containing ICT reported higher treatment acceptance (median SICT score: 4.0 versus 3.6, p = 0.038) and greater satisfaction with the burden of their ICT (median SICT score: 4.4 versus 3.9, p = 0.033). CONCLUSION: TDT patients prefer to receive oral ICT and are more satisfied of the burden of deferasirox-containing ICT, even though those receiving parenteral ICT are more satisfied by the effectiveness of their treatment. No differences in HRQoL were not noted between patients receiving parenteral versus oral ICT.

Cardiac mortality in {beta}-thalassemia major: resting but not dobutamine stress echocardiography predicts mortality among initially cardiac disease-free patients in a prospective 12-year study.

AIMS: Cardiac death remains the principal cause of mortality in beta-thalassemia major (beta-TM). Echocardiography may provide additional information, incremental to haematological profile, both for guiding chelation therapy and to assess prognosis. METHODS AND RESULTS: Between 1993 and 1995, 36 patients with beta-TM and normal cardiac function and 25 normal volunteers underwent evaluation using resting and dobutamine stress echocardiography (DSE). Dobutamine stress echocardiography was performed at baseline and repeated after 2 years. The primary endpoint was cardiac mortality. During a 12-year observation period, seven patients (19%) died from heart failure. All seven deaths occurred among the cohort of 12 patients with median ferritin concentrations >or= 2800 ng/mg. In addition, a resting left ventricular ejection fraction (LVEF) < 60% was also associated with increased late mortality. In multivariate analysis, increased serum ferritin levels and reduced LVEF but not DSE or other haematological variables were independent survival determinants. CONCLUSION: Resting LVEF provides prognostic information that is additional to ferritin levels among patients with beta-TM.
