A recent study conducted by researchers at Guangdong Pharmaceutical University evaluated the immunization efficacy and adverse reactions of hepatitis B vaccination in children with thalassemia minor. The study included 625 children and found that the immunization response to the hepatitis B vaccine in children with thalassemia minor was comparable to healthy children, with no abnormal adverse effects observed. The study also identified factors such as the duration of immunization and age at completion of vaccination that influenced the levels of HBsAb (hepatitis B surface antibody) in children. The findings suggest that the protective duration of the hepatitis B vaccine may be reached after approximately 30 months of immunization. [Extracted from the article]

A recent study conducted by researchers at Chiang Mai University in Thailand explores the potential for reactivating fetal hemoglobin (HbF) production to alleviate symptoms of b-thalassemia, a form of congenital anemia. The study focuses on the role of prolyl hydroxylase domain enzymes (PHDs) in the oxygen-sensing pathway and their relationship to clinical phenotypes in b0-thalassemia/HbE disease. Through genetic modifications of the EGLN1 gene, which encodes PHD2, the researchers were able to reduce PHD2 expression and increase HbF expression levels in severe b-thalassemia erythroblasts. These findings suggest that targeting the PHD2 functional domains could be a promising therapeutic strategy for b-thalassemia. [Extracted from the article]

A study conducted by researchers at Lady Hardinge Medical College and Associated Hospitals in New Delhi, India, explores the issue of alloimmunization in patients with thalassemia and sickle cell disease (SCD) who receive blood transfusions. Alloimmunization, the development of antibodies against foreign antigens, can complicate transfusion management and lead to adverse reactions. The study highlights the need for better understanding of the pathogenesis and prevention of alloimmunization, as well as the importance of transfusion guidelines and practices. The researchers conclude that there is limited evidence on best practices for transfusion management of SCD and thalassemia, and further research is needed. [Extracted from the article]

A recent study conducted in Greece examined the vaccination practices and knowledge among adults with hemoglobinopathies, such as sickle cell disease and thalassemia.

A recent study conducted by researchers at the National University of Medical Sciences (NUMS) in Pakistan aimed to assess the frequency of molecular and serological markers of Hepatitis B virus (HBV), Hepatitis C virus (HCV), and Human Immunodeficiency Virus (HIV) among multi-transfused beta-thalassemia patients. The study included 105 beta-thalassemia patients, with 27.6% testing positive for HBV and 15.2% testing positive for HCV. No patients were found to be reactive for anti-HIV. The researchers concluded that HCV was the most prevalent infection among beta-thalassemia patients, and recommended the use of nucleic acid testing (NAT) to detect viremia in both seropositive and seronegative cases, which would aid in early identification and treatment of infected patients.

A recent study conducted by researchers at Shiraz University of Medical Sciences in Iran has explored the synthesis of deferiprone, an iron-chelating drug used in the treatment of iron-overload diseases such as thalassemia. Thalassemia is a genetic disease that affects human health and requires chelation therapy to remove excess iron from the body. Deferiprone and deferoxamine are commonly used as iron chelating agents, and this study presents an efficient method for the synthesis of deferiprone. The researchers suggest that domestic production of this drug could help reduce costs and make it more accessible to patients. [Extracted from the article]

A recent study conducted by researchers at Yangzhou University in China has found that depleting the microRNA-144/451 (miR-144/451) gene locus can alleviate anemia in mice with beta-thalassemia. Beta-thalassemia is a hereditary disease caused by mutations in the beta-globin gene. The researchers discovered that the depletion of miR-144/451 resulted in improved levels of red blood cells, hemoglobin, and hematocrit, as well as decreased spleen size and erythroblast count. These findings suggest that targeting miR-144/451 could be a potential therapeutic strategy for treating beta-thalassemia. [Extracted from the article]

A recent study conducted at Thammasat University in Thailand examined the prevalence of habitual snoring (HS) and its impact on quality of life in pediatric thalassemia patients. The study found that 48.2% of the patients reported snoring, with 19.9% experiencing HS. The prevalence of HS did not significantly differ between non-transfusion dependent thalassemia (NTDT) and transfusion dependent thalassemia (TDT) patients. Risk factors associated with HS included nasal congestion and male gender. Overall, the study concluded that thalassemia children generally exhibited a good quality of life, and the standard care provided for TDT patients may contribute to reducing nasopharyngeal narrowing.

According to a preprint abstract, researchers have conducted in utero hematopoietic stem cell transplantation (HSCT) for Fanconi Anemia (FA), a genetic disorder that leads to bone marrow failure and malignancies. FA can be cured postnatally through HSCT, but this requires chemotherapy and/or irradiation-based conditioning, which can have side effects. The researchers performed in utero HSCT in FA mouse models and observed successful engraftment of healthy donor cells, suggesting that in utero HSCT may be a safe and curative prenatal treatment for FA. This research has not yet been peer-reviewed. [Extracted from the article]

A new report from the First Affiliated Hospital of Guangxi Medical University in Nanning, China, discusses the development of a prediction model for secondary failure of platelet recovery (SFPR) in patients with b-thalassemia major (b-TM) after hematopoietic stem cell transplantation (HSCT). The researchers used a retrospective study to develop the prediction model, which was based on pretransplant serum ferritin, hepatomegaly, mycophenolate mofetil use, and posttransplant serum albumin. The model showed good predictive ability and may be used by clinicians to identify SFPR patients early and recommend effective preventive measures. This research provides valuable insights for the treatment and management of thalassemia patients undergoing HSCT. [Extracted from the article]

A recent preprint abstract discusses a potential treatment for alpha-thalassemia, a genetic blood disorder. The researchers developed a genome editing strategy using Cas9/AAV6 to insert a functional alpha-globin gene into patient-derived hematopoietic stem and progenitor cells.

A recent study conducted by Zhengzhou University in China has examined the onset and progression of oral potentially malignant disorders (OPMD) in patients with Fanconi anemia (FA). The study found that 14% of FA patients were diagnosed with OPMD, and 41.1% of those patients further developed oral squamous cell carcinoma (OSCC) at a young age. The evidence suggests that FA may increase the risk of cancer development in the oral cavity. The study emphasizes the importance of close surveillance and early detection of oral cancer in FA patients with OPMD. [Extracted from the article]

A recent study conducted at the Children's Hospital of Philadelphia has found that deregulated protein homeostasis is a contributing factor to the limited expansion of the fetal hematopoietic stem cell pool in Fanconi anemia, a DNA repair disorder that leads to bone marrow failure. The researchers discovered that increased protein synthesis rates in the fetal hematopoietic stem cell pool result in the accumulation of misfolded proteins and endoplasmic reticulum stress, which hampers midgestational expansion. However, the use of a chemical chaperone called tauroursodeoxycholic acid was found to restore protein folding and prevent the accumulation of unfolded proteins, thereby rescuing the fetal hematopoietic stem cell numbers. The study also revealed that proteostasis deregulation is driven by excessive sterile inflammatory activity in hematopoietic and stromal cells within the fetal liver, and dampened Type I interferon signaling can restore the fetal hematopoietic stem cells to normal levels. Overall, the study highlights the importance of protein homeostasis in regulating the fate and function of hematopoietic stem cells. [Extracted from the article]
