Inhibition of Fibroblast Growth Factor-23 (FGF-23) Rescues Bone and Hematopoietic Stem Cell Niche Defects in Beta-Thalassemia, Uncovering the Missing Link between Hematopoiesis and Bone
Abstract The bone marrow (BM) niche regulation and interactions with hematopoietic stem cells (HSC) have been extensively studied in steady state conditions and malignancies, but are still underexplored in hematological inherited disorders. We provided the first demonstration of impaired HSC function caused by an altered BM niche in a non-malignant disease, beta-thalassemia (BT) (Aprile et al., Blood 2020). BT is a globally widespread congenital hemoglobin disorder, resulting in severe anemia, ineffective erythropoiesis and multi-organ secondary complications, including bone alterations. Correction of the genetic defect is achieved by transplantation of HSC from healthy donors or autologous…
Diagnosis of chronic anaemia in gastrointestinal disorders: a guideline by the Italian Association of Hospital Gastroenterologists and Endoscopists (AIGO) and the Italian Society of Paediatric Gastroenterology Hepatology and Nutrition (SIGENP)
Anaemia is a common pathologic condition, present in almost 5% of the adult population. Iron deficiency is the most common cause; other mechanisms can be involved, making anaemia a multi-factorial disorder in most cases. Anaemia being a frequent manifestation in the diseases of the gastrointestinal tract, patients are often referred to gastroenterologists. Furthermore, upper and lower endoscopy and enteroscopy are pivotal to the diagnostic roadmap of anaemia. In spite of its relevance in the daily clinical practice, there is a limited number of gastroenterological guidelines dedicated to the diagnosis of anaemia. For this reason, the Italian Association of Hospital Gastroenterologists and E…
