Case Report: Recurrence of recipient-derived erythropoiesis in hematopoietic stem cell transplant for sickle-cell anemia: multi-lineage chimerism analysis as a tool to distinguish atypical pure red cell aplasia from poor erythroid engraftment

Experience in hematopoietic stem cell transplant (HSCT) as a long-term curative treatment for sickle-cell anemia (SCA) has been gathered over the last 30 years. Sustained engraftment to restore normal erythropoiesis remains the primary aim of HSCT in t…

Case Report: dupilumab for severe pruritus in pediatric recessive dystrophic epidermolysis bullosa—a longitudinal clinical assessment and literature review
