Sepax-2 cell processing device: a study assessing reproducibility of concentrating thawed hematopoietic progenitor cells.

Background: Autologous hematopoietic progenitor cell (HPC) transplantation is currently the standard of care for a fraction of patients with newly diagnosed myelomas and relapsed or refractory lymphomas. After high-dose chemotherapy, cryopreserved HPC are either infused directly after bedside thawing or washed and concentrated before infusion. We previously reported on the comparability of washing/concentrating HPC post-thaw vs.

GB virus C infection in patients with type II mixed cryoglobulinemia.

Background: Hepatitis C virus (HCV) infection is present in most but not all patients with type II mixed cryoglobulinemia.

Objective: To investigate the role of GB virus C (GBV-C) in type II mixed cryoglobulinemia.

Design: Retrospective study of serum and cryoprecipitate samples.
