A Cross-Sectional, Multicentric, Disease-Specific, Health-Related Quality of Life Study in Greek Transfusion Dependent Thalassemia Patients.

The assessment of health-related quality of life (HRQoL) in thalassemia offers a holistic approach to the disease and facilitates better communication between physicians and patients. This study aimed to evaluate the HRQoL of transfusion-dependent thalassemia (TDT) patients in Greece. This was a multicentric, cross-sectional study conducted in 2017 involving 283 adult TDT patients. All participants completed a set of two QoL questionnaires, the generic SF-36v2 and the disease-specific TranQol. Demographic and clinical characteristics were used to predefine patient subgroups. Significant factors identified in the univariate analysis were entered into a multivariate analysis to assess their effect on HRQoL. The SF-36 scores of TDT patients were consistently lower compared to the general population in Greece. The mean summary score of TranQol was relatively high (71 ± 14%), exceeding levels observed in national surveys in other countries. Employment emerged as the most significant independent factor associated with better HRQoL, whereas age had the most significant negative effect. This study represents the first comprehensive QoL assessment of a representative sample of the TDT population in Greece. The implementation of TranQol allowed for the quantification of HRQoL in Greece, establishing a baseline for future follow-up, and identifying more vulnerable patient subgroups.

Rivaroxaban Use in Patients with Hemoglobinopathies.

The use of rivaroxaban in patients with hemoglobinopathies and thrombotic events has not been studied extensively. Here we present eight cases of such patients, five receiving rivaroxaban for stroke and systemic embolism prevention due to non-valvular atrial fibrillation and three for deep vein thrombosis treatment. The follow-up period ranged from 6 to 34 months. During this period none of the patients experienced any thrombotic or bleeding event.There were no other adverse events reported. Further studies with larger numbers of patients with hemoglobinopathies are needed to determine the use of rivaroxaban and ensure its safety in this patient setting.

A Case of Fatal Agranulocytosis That Developed in a Patient with ß-Thalassemia Major Treated with Deferiprone.

A 29-year-old male with transfusion-dependent ß-thalassemia major (ß-TM), splenectomized and on chelation therapy with deferiprone (DFP or L1) due to heart and liver hemosiderosis, presented with high fever and agranulocytosis. Deferiprone was discontinued and a broad spectrum antibiotic therapy was started intravenously. The patient remained febrile and showed no recovery of neutrophil count even after the initiation of granulocyte colony-stimulation factor (G-CSF). After 12 days at the hospital, he developed respiratory failure and was transferred to the intensive care unit (ICU) where he developed multi-organ failure and died 3 days later. To investigate the mechanism of agranulocytosis, bone marrow mononuclear cells of a healthy volunteer were plated on culture dishes, with or without the patient's serum. The observation of colony forming units of progenitor cells in dishes that contained the patient's serum, provided inconclusive explanation of the possible mechanism of DFP-induced agranulocytosis. This is a case of fatal agranulocytosis developing in a patient being treated with DFP, a well recognized but rare complication of this drug. Further studies are required in order to elucidate the possible pathogenic mechanism of agranulocytosis due to DFP and to provide clear guidelines in order to best care for the patient.
