Abstract (original English)

Background Nonregenerative anemia is occasionally seen in dogs and can be caused by many factors, among which nonregenerative immune-mediated anemia (NRIMA) and pure red cell anemia are relatively common causes. These are thought to be caused by immune-mediated destruction of the erythroid lineage and are treated with immunosuppressive drugs, but some of them are refractory or recurrent, so new treatments are needed. Objectives To examine the efficacy of allogeneic adipose-derived stem cells (ADSCs) for the treatment of nonregerative anemia in dogs. Methods ADSCs were administered to total five nonregenerative anemia cases; two NRIMA cases and two suspected NRIMA cases that were refractory to immunosuppressive agents, and one NRIMA case that has not been treated with immunosuppressive agents. Results In all cases, anemia was improved, and blood transfusion was no longer necessary. Conclusions This study suggests that allogeneic ADSCs may be one of the rescue therapies for the refractory immune-mediated anemia in dogs.

What this study does not prove

  • • This study does not prove SVF is an approved treatment or a replacement for standard care.
