Myelodysplastic Syndrome (MDS) | Clinical Medicine

Premium Member Resources: https://ninjanerd.org Ninja Nerds! In this lecture, Professor Zach Murphy delivers a comprehensive and high-yield breakdown of Myelodysplastic Syndromes (MDS), focusing on the pathogenesis, clinical features, and diagnostic criteria of this group of clonal stem cell disorders. We begin with a review of normal hematopoiesis and then transition into the mechanisms behind ineffective myeloid cell production, including key genetic mutations and chromosomal abnormalities that contribute to dysplasia and cytopenias. We then cover the clinical presentation of MDS, emphasizing symptoms related to anemia, neutropenia, and thrombocytopenia, as well as findings like macrocytic anemia, recurrent infections, and bleeding tendencies. This lecture highlights the hallmark bone marrow biopsy findings, including hypercellularity with dysplastic morphology, ring sideroblasts, and increased blasts in higher-risk cases. We provide a step-by-step review of how to interpret peripheral smears and cytogenetic analysis and apply prognostic scoring systems like the IPSS-R. We also compare MDS with other overlapping conditions such as aplastic anemia, acute myeloid leukemia, and vitamin B12/folate deficiency, helping you differentiate them based on lab findings, marrow features, and clinical context. You’ll learn about treatment strategies, from supportive care with transfusions and growth factors to disease-modifying agents like hypomethylating therapy, and the role of stem cell transplantation in eligible patients.
