Hemorheological profiles and chronic inflammation markers in transfusion-dependent and non-transfusion- dependent thalassemia.

The rheological properties of blood play an important role in regulating blood flow in micro and macro circulation. In thalassemia syndromes red blood cells exhibit altered hemodynamic properties that facilitate microcirculatory diseases: increased aggregation and reduced deformability, as well as a marked increase in adherence to the vascular endothelial cells. A personalized approach to treating thalassemia patients (transfusions, iron chelation, and splenectomy), has increased patients' life expectancy, however they generally present many complications and several studies have demonstrated the presence of high incidence of thromboembolic events.

Innovative screening test for the early detection of sickle cell anemia.

In this study, the capability of thermogravimetry in conjuction with a multivariate statistical analysis, was investigated for the screening of Sickle Cell Anemia (SCA), a hereditary disorder of hemoglobin characterized by severe hemolytic anemia with different severe clinical manifestations. SCA results from a mutation in the sixth codon of the beta globin gene, which results in the substitution of glutamic acid for valine and leads to the production of an altered form of hemoglobin, hemoglobin S (HbS). People with this disorder have atypical hemoglobin molecules which tend to aggregate together and form filaments inside the red blood cells.

An Innovative Multilevel Test for Hemoglobinopathies: TGA/Chemometrics Simultaneously Identifies and Classifies Sickle Cell Disease From Thalassemia.

Hemoglobinopathies are the most common genetic disorder wordlwide and because of migrations are become an emerging global health problem. Screening programmes for Sickle cell disease and Thalassemia have been implemented in some countries, but are not a common practice, due to a lack in the accuracy of the methods and to the costs of the analyses. The objective of this study was the application of the thermogravimetry coupled to chemometrics as new screening method to perform an early diagnosis of thalassemia and sickle cell disease.

Phenotypical and functional abnormalities of circulating neutrophils in patients with β-thalassemia.

β-Thalassemia is an inherited single gene disorder related to reduced synthesis of the β-globin chain of hemoglobin. Patients with β-thalassemia present variable clinical severity ranging from asymptomatic trait to severe transfusion-dependent anemia and multiple organs complications. Moreover, multiple immune abnormalities are a major concern in β-thalassemia patients.

COVID-19 Sepsis and Microcirculation Dysfunction.

The spreading of Coronavirus (SARS-CoV-2) pandemic, known as COVID-19, has caused a great number of fatalities all around the World. Up to date (2020 May 6) in Italy we had more than 28,000 deaths, while there were more than 205.000 infected.
