SUMMARY

Acute graft-versus-host disease (aGVHD) remains a severe complication after allogeneic stem cell transplantation (alloHCT). It is a disregulated immune process, during which the immune cells of the donor attack the healthy tissues in the immunocompromised host. Over the past two decades, progress in understanding its pathophysiology have helped redefine aGVHD reactions and clinical presentations. Typically, the disease presents with serious inflammatory lesions mainly in the skin, gut and liver. Its severity is assessed by gathering clinical signs and dysfunctions of each organ. Despite standard prophylaxis regimens, aGVHD still occurs in approximately 30–60% of transplanted patients and remains a major cause of transplant-related morbidity and mortality. Hence, there is an urgent need for optimising preventive strategies. In this review, we give insights on how to make an accurate diagnosis and scoring assessment of aGVHD, propose a short overview of the current knowledge about its immunobiology and discuss the current and developing strategies for prevention.

Blinatumomab: beyond clinical trials

BJH - volume 8, issue 3, june 2017

C. Graux MD, PhD

SUMMARY

Immunotherapy is an alternative treatment modality for poor conditions associated with chemoresistance like refractory/relapsing primary B-precursor acute lymphoblastic leukaemia or minimal residual disease persistence. The immunotherapeutic effect of allogeneic stem cell transplantation is largely exploited in this context but graft-versus-host disease remains a major concern. Recently, improvements have been made in selectively engaging the immune system against the persistent disease. Blinatumomab is a dual binding antibody construct that redirects any T lymphocytes against B-precursor acute lymphoblastic leukaemia blasts. It shows a very good activity in monotherapy in those poor risk conditions and is associated with a low toxicity profile suggesting this use earlier and in combination in the therapeutic course of B-precursor acute lymphoblastic leukaemia patients. In this article, after a short overview of immunotherapeutic advances in B-precursor acute lymphoblastic leukaemia, the results of the main trials conducted with blinatumomab are discussed and put in perspective.
