Graft-versus-Host Disease in a Dog After Reduced-intensity Hematopoietic Stem Cell Transplantation from a DLA-identical Littermate.

چکیده
BACKGROUND Graft-versus-host disease (GvHD) is an adverse effect following hematopoietic stem cell transplantation (HSCT) in humans. Dogs represent a key model organism for the development of treatment protocols for HSCT. However, detailed descriptions of canine GvHD and its treatment are rare. Herein we describe the development of canine GvHD and therapeutic intervention. MATERIALS AND METHODS A female Beagle received an allogeneic HSCT from a dog leukocyte antigen-identical littermate (conditioning with 4.5 Gy total body irradiation; immunosuppression with cyclosporine A). RESULTS GvHD developed at day +52 and was treated with methylprednisolone, cyclosporine A, antibiotics, antiviral medication and analgesics. The dog initially responded to the treatment but GvHD relapsed twice. Within one week after discontinuation of glucocorticoid, GvHD recurred resulting in inevitable euthanasia of the animal. CONCLUSION GvHD represents a life-threatening disease after HSCT in canines. Immediate therapeutic treatment is indicated and even a successful initial treatment response does not necessarily prevent GvHD recurrence.

Assessment of Cyclosporine Serum Concentrations on the Incidence of Acute Graft versus Host Disease Post Hematopoietic Stem Cell Transplantation
Allogeneic hematopoietic stem cell transplantation (HSCT) is a curative treatment option for hematological disorders. Cyclosporine (CsA) is one of the major immunosuppressive agents for the prophylaxis against graft versus host disease (GvHD). In this retrospective study, we evaluated the effects of CsA serum levels on the incidence of acute GvHD and transplant outcomes. 103 adult patients rece...

Background: Allogenic hematopoietic stem cell transplantation (HSCT) is a strategy used for treatment of different malignant diseases. However, success of allo-HSCT can be hampered by graft-versus-host-disease (GVHD). Natural killer (NK) cells may play an important role in activating antigen presenting cells and subsequent activation of T cells. The main purpose of this study was the evaluation...

Background: Bone marrow transplantation (BMT) is considered as a curative therapy for a broad range of diseases. However, complications such as relapse and graft versus host disease (GVHD) may be observed following BMT. Chimerism analysis serves as a reliable indicator of transplant outcome. Complete chimerism refers to the complete replacement of hematopoietic system by donor cells, while mixe...

We have studied graft-versus-host disease (GVHD) after transplantation of allogeneic peripheral blood stem cells (PBSC) mobilized by either recombinant canine granulocyte colony-stimulating factor (rcG-CSF) alone or combined with stem cell factor (rcSCF). These studies were prompted by the observation of extremely rapid and sustained engraftment of growth factor-mobilized PBSC in the autologous...
