RESUMO

Patients with transfusion-dependent beta (ß)-thalassaemia experience a broad range of complications. ULYSSES, an epidemiological, multicentre, retrospective cross-sectional study, aimed to assess the prevalence and severity of treatment and disease complications, capture disease management and identify predictors of complications in patients with transfusion-dependent ß-thalassaemia, treated in routine settings in Greece. Eligible patients were adults diagnosed with ß-thalassaemia ≥12 months before enrolment and having received ≥6 red blood cell (RBC) units (excluding elective surgery) with no transfusion-free period ≥35 days in the 24 weeks before enrolment. Primary data were collected at a single visit and through chart review. Between Oct 21, 2019, and Jun 15, 2020, 201 eligible patients [median (interquartile range, IQR) age 45.7 (40.2-50.5) years; 75.6% > 40 years old; 64.2% female] were enrolled, a mean (standard deviation) of 42.9 (7.8) years after diagnosis. Median (IQR) age at diagnosis and RBC transfusion initiation were 0.8 (0.4-2.8) and 1.3 (1.0-5.0) years, respectively. From diagnosis to enrolment, patients had developed a median of six (range: 1-55) complications; 19.6% were grade ≥3. The most represented complications were endocrine/metabolic/nutrition disorders (91.5%), surgical/medical procedures (67.7%) and blood/lymphatic system disorders (64.7%). Real-world data generated by ULYSSES underscore the substantial complication burden of transfusion-dependent ß-thalassaemia patients, routinely managed in Greece.
