Special Issue Information

Dear Colleagues,

Hereditary anemias are genetically and clinically highly variable diseases (constituted by mild, moderate, or severe forms) and represent a major health problem worldwide, causing childhood mortality and morbidity, especially in developing countries. Even though for many hereditary anemias no definitive cure is available, supportive treatments have significantly contributed to the improvement of the quality of life of affected people (including an increased survival even in the most severe forms of the diseases).

Anemia may be classified as impaired red blood cell (RBC) production or increased RBC destruction (hemolytic anemias). The underlying cause of hereditary anemia may be due to hemoglobinopathies (for instance thalassemias and sickle-cell disease), defects of the red blood cell membrane (for instance hereditary spherocytosis and hereditary elliptocytosis), enzyme deficiencies (for instance glucose-6-phosphate dehydrogenase, the most common cause of acute hemolytic anemia), or inherited bone marrow failure syndromes (such as Fanconi anemia, Diamond–Blackfan anemia, and Shwachman–Diamond syndrome).

The Special Issue will focus on tools available to the scientific community and patients for up-to-date molecular diagnosis and therapeutic approaches for hereditary anemias, including DNA/RNA-based approaches, and cellular and gene therapies. Articles describing clinical and preclinical research will be also considered.

The main topics include, but are not limited to:

  • Hereditary anemias
  • Molecular basis and genetics/epigenetics of hereditary anemias
  • Thalassemia
  • Sickle-cell disease
  • Fanconi anemia
  • Hereditary spherocytosis
  • Diamond–Blackfan anemia
  • Swachman–Diamond syndromes
  • OMICS analyses
  • Defects of red blood cell membrane
  • Erythropoiesis and abnormal erythropoiesis
  • Regulation of iron metabolism
  • MicroRNAs
  • Long non-coding RNAs
  • In vitro experimental model systems
  • In vivo experimental model systems, including transgenic animals
  • Molecular diagnosis
  • Prenatal diagnosis
  • Therapeutic treatments of hereditary anemias
  • Gene therapy
  • Induction of Fetal Hemoglobin

Increased Expression of α-Hemoglobin Stabilizing Protein (AHSP) mRNA in Erythroid Precursor Cells Isolated from β-Thalassemia Patients Treated with Sirolimus (Rapamycin)

Background/Objectives: in β-thalassemia, important clinical complications are caused by the presence of free α-globin chains in the erythroid cells of β-thalassemia patients. These free α-globin chains are present in excess as a result of the lack of β-globin chains to bind with; they tend to aggregate and precipitate, causing deleterious effects and overall cytotoxicity, maturation arrest of the erythroid cells and, ultimately, ineffective erythropoiesis. The chaperone protein α-hemoglobin-stabilizing protein (AHSP) reversibly binds with free α-globin; the resulting AHSP-αHb complex prevents aggregation and precipitation. Sirolimus (rapamycin) has been previously demonstrated to induce expression of fetal hemoglobin and decrease the excess of free α-globin chain in the erythroid cells of β-thalassemia patients. The objective of this study was to verify whether sirolimus is also able to upregulate AHSP expression in erythroid precursor cells (ErPCs) isolated from β-thalassemia patients. Methods: the expression of AHSP genes was analyzed by measuring the AHSP mRNA content by real-time quantitative PCR (RT-qPCR) and the AHSP protein production by Western blotting. Results: AHSP gene expression was found to be higher in ErPCs of β-thalassemia patients in comparison to ErPCs isolated from healthy subjects. In addition, AHSP expression was further induced by treatment of β-thalassemia ErPCs with sirolimus. Finally, AHSP mRNA was expressed at an increased level in ErPCs of sirolimus-treated β-thalassemia patients participating in the NCT03877809 Sirthalaclin clinical trial. Conclusions: this exploratory study suggests that AHSP expression should be considered as an endpoint in clinical trials based on sirolimus. Full article

Introduction: The beneficial effects of physical exercise on functional capacity and inflammatory response are well-known in cardiovascular diseases; however, studies on sickle cell disease (SCD) are limited. It was hypothesized that physical exercise may exert a favorable effect on the inflammatory response of SCD patients, contributing to an improved quality of life. This study aimed to evaluate the effect of a regular physical exercise program on the anti-inflammatory responses in SCD patients. Methods: A non-randomized clinical trial was conducted in adult SCD patients. The patients were divided into two groups: 1—Exercise Group, which received a physical exercise program three times a week for 8 weeks, and; 2—Control Group, with routine physical activities. All patients underwent the following procedures initially and after eight weeks of protocol: clinical evaluation, physical evaluation, laboratory evaluation, quality of life evaluation, and echocardiographic evaluation. Statistical analysis: Comparisons between groups were made using Student’s t-test, Mann–Whitney test, chi-square test, or Fisher’s exact test. Spearman’s correlation coefficient was calculated. The significance level was set at p < 0.05. Results: There was no significant difference in inflammatory response between the Control and Exercise Groups. The Exercise Group showed an improvement in peak VO2 values (p < 0.001), an increase in the distance walked (p < 0.001), an improvement in the limitation domain due to the physical aspects of the 36-Item Short Form Health Survey (SF-36) quality of life questionnaire (p = 0.022), and an increase in physical activity related to leisure (p < 0.001) and walking (p = 0.024) in the International Physical Activity Questionnaire (IPAQ). There was a negative correlation between IL-6 values and distance walked on the treadmill (correlation coefficient −0.444, p = 0.020) and the estimated peak VO2 values (correlation coefficient −0.480; p = 0.013) in SCD patients in both groups. Conclusions: The aerobic exercise program did not change the inflammatory response profile of SCD patients, nor did it show unfavorable effects on the parameters evaluated, and patients with lower functional capacity were those with the highest levels of IL-6.
