Plasma samples were collected and plasma protein levels analyzed from all IPS patients pretransplant (IPS-PreHCT), and at the time of initial IPS diagnosis (IPS-Dx). In addition, control plasma samples were collected between day 14 and 21 after transplantation from allogeneic HCT recipients without complications (Control [BMT]), and from normal (nontransplantation) individuals (Control [NL]). No differences were observed between responders and nonresponders at the time of diagnosis, IPS-Dx (Resp) versus IPS-Dx (NR). In addition, plasma samples were collected at the time of study completion in those subjects that responded to therapy; n = 7 to 14 per group.
LOD indicates limit of detection; and ND, not done.
