Oral supplements of vitamin E improve measures of oxidative stress in plasma and reduce oxidative damage to LDL and erythrocytes in β-thalassemia intermedia patients

Fifteen beta-thalassemia intermedia patients, not requiring chronic transfusional therapy, were monitored in order to check their antioxidant status, and the lipid oxidation products in plasma, LDL, and erythrocytes before and during a 9-month oral treatment with 600 mg/day vitamin E. The low level of vitamin E, and high level of malondialdehyde in plasma clearly tended to normalize after three months (P < .001), and were quite similar to control after six months. The abnormally low level of vitamin E in LDL and the four times higher than control basal level of conjugated dienes (LDL-CD), were not modified after three months of treatment. Significant changes of LDL-VE (P < .05) and of the b…

A Patient with Sickle Cell Disease and Recurrent Venous Thromboembolism after Renal Transplantation

Venous thromboembolism (VTE) is a life-threatening complication, especially in case of recurrence. The appropriate duration of anticoagulant treatment following the first event is crucial. Risk factors that increase the risk of recurrence of VTE are many, and include medications, kidney disease, renal transplantation (RT), and a diagnosis of sickle cell disease (SCD). There are currently no guidelines that define the duration of anticoagulant therapy after the first event in a patient with RT. We report a case of recurring episodes of VTE after RT in a SCD patient. Our case suggests that the use of a long-term anticoagulant treatment may be recommended in patients with SCD and RT after the …

Hepatocellular carcinoma in patients with thalassaemia syndromes: clinical characteristics and outcome in a long term single centre experience

Nonsense-mediated decay mechanism is a possible modifying factor of clinical outcome in nonsense cd39 beta thalassemia genotype

Nonsense-mediated mRNA decay (NMD) is a surveillance system to prevent the synthesis of non-functional proteins. In &beta;-thalassemia, NMD may have a role in clinical outcome. An example of premature translation stop codons appearing for the first time is the &beta;-globin cd39 mutation; when homozygous, this results in a severe phenotype. The aim of this study was to determine whether the homozygous nonsense cd39 may have a milder phenotype in comparison with IVS1,nt110/cd39 genotype. Genotypes have been identified from a cohort of 568 patients affected by &beta;-thalassemia. These genotypes were compared with those found in 577 affected fetuses detected among 2292 prenatal diagnoses. The…

The First Case of Haemophagocytic Lymphohistiocytosis Triggered by the Booster Dose of Anti-SARS-CoV-2 Vaccine in a Patient with β-Thalassemia

Background: Haemophagocytic lymphohistiocytosis (HLH) is a rare and potentially life-threatening systemic hyperinflammatory disease, which can have several aetiologies. Clinical case: a 48-year-old woman affected by a transfusion-dependent β-thalassemia was hospitalized in our haematology unit presenting with intermittent fever, haepatosplenomegaly and pancytopenia, which developed a few days after the booster dose of anti-SARS-CoV-2 mRNA vaccine. The investigations performed during hospitalization led to a diagnosis of HLH and steroid therapy where IV dexamethasone was initiated and provided benefits. Conclusions: the severity of HLH mandates early treatment, but the management of patients…

β-Thalassemia heterozygote state detrimentally affects health expectation.

Background: Thalassemia minor (Tm) individuals, are generally considered healthy. However, the prognosis of Tm individuals has not been extensively studied. The aim of this study was to evaluate the prognosis of Tm versus controls without β-thalassemia carrier state. Methods: A total of 26,006 individuals seeking thalassemia screening at the AOOR Villa Sofia-V. Cervello, Palermo (Italy) were retrospectively studied. Logistic penalised regression model was used to estimate risk of potential complications and survival techniques were used to study mortality. Results: We identified a total of 4943 Tm and 21,063 controls. Tm was associated with significantly higher risks of hospitalisation for …

Cardiac complications in thalassemia: noninvasive detection methods and new directions in the clinical management.

The natural history of thalassemia has shown substantial change during these years. This applies for each aspect of the pathology (for example, endocrinological, hepatological and psychological) and also for the pathology that has presented and still presents the main cause of death: myocardial dysfunction. In this review, the pathophysiology of cardiac complications, possible role of myocarditis, new knowledge on pathogenesis, and noninvasive detection methods for iron overload in the heart are pointed out. Prophylaxis of cardiomyopathy and new therapy strategies of myocardial dysfunction, including the impact of the new chelation treatment, are discussed.
