Pure red cell aplasia

Pure red cell aplasia is a rare hematologic syndrome characterized by a profound failure of erythropoiesis that selectively impacts the red blood cell lineage while preserving normal granulopoiesis and megakaryopoiesis Pathophysiologically driven by immune-mediated, clonal, or direct cytotoxic destruction and maturation arrest of erythroid progenitors, the condition is clinically defined by severe normocytic normochromic anemia, profound reticulocytopenia, and a near-complete absence of erythrob...

It can manifest in pediatric populations as a congenital disorder, such as Diamond-Blackfan anemia, or in adults as an acquired condition secondary to autoimmune diseases, thymomas, lymphoproliferative disorders, viral infections like parvovirus B19, or adverse drug reactions Pathophysiologically driven by immune-mediated, clonal, or direct cytotoxic destruction and maturation arrest of erythroid progenitors, the condition is clinically defined by severe normocytic normochromic anemia, profound ...
