Iron overload in acquired sideroblastic anemias and MDS: pathophysiology and role of chelation and luspatercept.

Besides transfusion therapy, ineffective erythropoiesis contributes to systemic iron overload in myelodysplastic syndromes with ring sideroblasts (MDS-RS) via erythroferrone-induced suppression of hepcidin synthesis in the liver, leading to increased intestinal iron absorption. The underlying pathophysiology of MDS-RS, characterized by disturbed heme synthesis and mitochondrial iron accumulation, is less well understood. Several lines of evidence indicate that the mitochondrial transporter ABCB7 is critically involved.

Long-read transcriptome sequencing of CLL and MDS patients uncovers molecular effects of mutations.

Mutations in splicing factor 3B subunit 1 () frequently occur in patients with chronic lymphocytic leukemia (CLL) and myelodysplastic syndromes (MDSs). These mutations have different effects on the disease prognosis with beneficial effect in MDS and worse prognosis in CLL patients. A full-length transcriptome approach can expand our knowledge on mutation effects on RNA splicing and its contribution to patient survival and treatment options.

MDS patient registries - achievements and challenges.

Since the late 1980s, patient registries have played a pivotal role in the elucidation of rare diseases. For myelodysplastic syndromes (MDS), they revealed the disease actually to be diverse rather than rare. Registry data enabled the definition of various MDS subtypes and prognostic scores tailoring therapy.

Introduction of a New Satellite Model for Participation in Clinical Trials in a Consortial Comprehensive Cancer Center with Four University Hospitals in Germany.

Introduction: The trend toward personalized medicine leads to very small study cohorts for clinical trials, which makes it difficult to recruit patients in a single study center. On the other hand, the administrative effort required to initiate a clinical trial is very high. As a result, Germany runs the risk of falling behind other countries as a trial location.
