Background: Psoriasis is an inflammatory skin disease in which the cells and molecules of innate and adaptive immunity are involved in the pathogenesis. Aplastic anemia is a bone marrow deficiency syndrome that is characterized by an extreme reduction in the number of blood cells as a result of failure in hematopoiesis. Allogenic hematopoietic stem cell transplantation is a promising treatment for Aplastic Anemia and it is important to note that other comorbid diseases like psoriasis- since both have some common pathogenetic mechanisims- might achieve remission after treatment.
Case: We present a 12-years-old male patient who underwent bone marrow transplantation for aplastic anemia and his psoriasis vulgaris lesions completely regressed. The final follow-up visit on day 150 also revealed no sign of the pre-transplantation skin and scalp lesions.
Conclusions: This is the first case of pediatric psoriasis together with aplastic anemia that achieved complete remission of psoriasis after bone marrow transplantation. Our case report needs to be supported by prospective studies involving larger patient populations.

Introduction: Iron overload (IOL) accumulates in myelodysplastic syndromes (MDS) from expanded erythropoiesis and transfusions. Somatic mutations (SM) are frequent in MDS and stratify patient risk. MDS treatments reversing or limiting transfusion dependence are limited.

Background: The aging of bone marrow mesenchymal stem cells (BMSCs) impairs bone tissue regeneration, contributing to skeletal disorders. LncRNA NEAT1 is considered as a proliferative inhibitory role during cellular senescence, but the relevant mechanisms remain insufficient. This study aims to elucidate how NEAT1 regulates mitotic proteins during BMSCs aging.

Background: Hematopoietic stem cell transplantation (HSCT) is a common therapy for many hematologic malignancies. While advances in transplant practice have improved cancer-specific outcomes, multiple and debilitating long term physical and psychologic effects remain. Patients undergoing allogeneic bone marrow transplantation (allo-BMT) are often critically ill at initial diagnosis and with necessary sequential treatments become increasingly frail and deconditioned.

Aims/hypothesis: Within the small intestine, neutrophils play an integral role in preventing bacterial infection. Upon interaction with bacteria or bacteria-derived antigens, neutrophils initiate a multi-staged response of which the terminal stage is NETosis, formation of protease-decorated nuclear DNA into extracellular traps. NETosis has a great propensity to elicit ocular damage and has been associated with diabetic retinopathy and diabetic macular oedema (DME) progression.
