Allogeneic haematopoietic stem cell transplantation resets T- and B-cell compartments in sickle cell disease patients.

Objectives: Allogeneic haematopoietic stem cell transplantation (allo-HSCT) is the only currently available curative treatment for sickle cell disease (SCD). Here, we comprehensively evaluated the reconstitution of T- and B-cell compartments in 29 SCD patients treated with allo-HSCT and how it correlated with the development of acute graft-versus-host disease (aGvHD).

Methods: T-cell neogenesis was assessed by quantification of signal-joint and β-chain TCR excision circles.

Long-Term Effects of Allogeneic Hematopoietic Stem Cell Transplantation on Systemic Inflammation in Sickle Cell Disease Patients.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the only currently available curative treatment for sickle cell disease (SCD). However, the effects of HSCT on SCD pathophysiology are poorly elucidated. Here, we assessed red blood cell (RBC) adhesiveness, intensity of hemolysis, vascular tone markers and systemic inflammation, in SCD patients treated with allogeneic HSCT.

Prolonged viremia in dengue virus infection in hematopoietic stem cell transplant recipients and patients with hematological malignancies.

Fever, skin rash, headache, and thrombocytopenia are considered hallmarks of dengue infection. However, these symptoms are frequently observed in infectious and non-infectious complications of hematopoietic stem cell transplant recipients and oncohematological patients. Thus, laboratory confirmation of dengue is relevant for prompt intervention and proper management of dengue in endemic and non-endemic regions.
