Is there a difference in phenotype between males and females with non-transfusion-dependent thalassemia? A cross-sectional evaluation.

Non-transfusion-dependent thalassemia includes a variety of phenotypes and genotypes that rarely require regular transfusions. However, these patients can experience a wide range of complications. The objective of this retrospective study was to verify whether there is a significant difference in non-transfusion-dependent thalassemia-related complications and treatment among males and females.We performed a re-analysis of samples evaluated in a previously published cross-sectional study, regarding 96 non-transfusion-dependent thalassemia patients followed at the 'UOSD Malattie Rare del Globulo Rosso' Centre of the Cardarelli Hospital in Naples, Italy.We found that females were more anemic than males, but there was no significant difference in prevalence of common complications among genders, except for hypogonadism. Furthermore, the transitory regular transfusions regimen in women who had been pregnant does not seem to have a significant impact on overall prognosis.In non-transfusion-dependent thalassemia patients, the lower levels of hemoglobin found in females do not seem to indicate a higher prevalence of complications.This data should be considered in studies with experimental treatments aiming to correct anemia in patients with non-transfusion-dependent thalassemia. It should probably also be taken into account in order to set up different transfusion regimens among genders in transfusion-dependent patients

A useful relationship between the presence of extramedullary erythropoeisis and the level of the soluble form of the transferrin receptor in a large cohort of adult patients with thalassemia intermedia: A prospective study

In thalassemia intermedia (TI), the increase in bone marrow hemopoietic activity frequently leads to extramedullary erythropoeisis (EMH), but its relationship with the soluble form of transferrin receptor (sTfR) which fully reflects the marrow erythropoietic activity, has not yet been explored. From January 2007 to December 2010, all TI patients attending at our center were prospectively enrolled to undergo sTfR assay and MRI or CT (if claustrophobic) scan evaluation for the presence of paraspinal EMH. A total of 59 patients with TI were studied; EMH involved 23 (39%) patients; overall, the concentration of sTfR varied from 2.6 to 20.6 (mean=8.7) mg/L, but in splenectomized group and in unsplenectomized group, it varied from 4.2 to 17.8 (mean±SD=9. 86±3.33) mg/L and from 2.6 to 20.6 (mean±SD=7.25±3.9) mg/L, respectively with a statistically significant intergroup difference (p<0.01). The cutoff point at 8.6 mg/L using the ROC curve showed a sensitivity of 78.3% and a specificity of 72.2%, in predicting EMH but, in unsplenectomized subgroup, they raised to 100% and 90.9%, respectively. These data showed that in TI the level of sTfR could represent a predictive factor of EMH particularly in patients with spleen. © Springer-Verlag 2012

La medicina di laboratorio: Gli Specialisti di domani

[Laboratory Medicine: specialists of tomorrow] Laboratory Medicine rides the wave of technological progress, the metamorphosis of information systems and data management. The Young Specialist is not a mere observer, but rather takes a leading role in this change, taking advantage of the opportunities offered by “omics” technologies, capturing new ideas and innovative stimuli that lead to a new concept of work and research oriented to health and prevention. Thanks to the support of international web platforms, training and exchange programs supported by the International Scientific Societies and Federations that favor professional and scientific growth, Young Scientists work in a global context. In this scenario, the SIBioC Young Scientists Study Group, with the auspices of SIBioC, EFLM and IFCC, organized a meeting on "Laboratory Medicine: Specialists of tomorrow" with the aim of discussing and highlighting some of the most important challenges, such as technological progress, training and internationalization of young people. Finally, the future of laboratory medicine looks at a multidisciplinary approach that leads to integrated diagnosis, identification of the frail patient, the use of the Point of Care Testing as an indispensable tool in crisis areas, making the dialogue between physician and laboratory specialist a fundamental step for the diagnosis and treatment with the final aim of a better outcome for the patient
