## Abstract Cyclosporine is commonly used as an immunosuppressive agent in both solid organ and bone marrow transplant. While used for graft rejection in organ transplantation, cyclosporine has been used to enable tolerance and for prevention of acute graft‐versus‐host disease in bone marrow transp

✦ Synopsis
We report a case of improved CD34 1 cell yields from peripheral blood stem cell (PBSC) collection following therapeutic plasma exchange (TPE) in a patient with elevated viscosity and coagulopathy. The patient was a 46-year-old male diagnosed with IgM lambda multiple myeloma that was largely unresponsive to standard chemotherapy. He had coagulopathy due to lymphoproliferative disease-associated acquired von Willebrand Factor (vWF) deficiency. The patient underwent two rounds of PBSC collections over 3 consecutive weeks (five total collections) prior to planned tandem transplant for multiple myeloma. Both rounds resulted in poor collections due to processing difficulties. It was decided to perform three TPEs daily immediately prior to attempting additional PBSC collections, to treat the patient's elevated viscosity and thereby potentially improve the efficiency of collections. Immediately following the three TPEs, two additional PBSC collections resulted in sufficient CD34 1 cells to proceed to transplant. Lower IgM and/or viscosity levels present after the three TPEs likely permitted successful collection of stem cells.

A high level of circulating nucleated red blood cells (NRBC) in patients with chronic myeloproliferative syndromes could potentially complicate peripheral blood stem cell (PSC) collection. The mononuclear NRBC might comprise a significant fraction of the total mononuclear cells in the final product.
## Abstract The recent development of reduced intensity conditioning and allotransplantation (RICT) has opened a new way to assure engraftment of donor cells while reducing early transplant‐related mortality. We evaluated the combination of high‐dose therapy and autologous peripheral blood stem cel
