Randomized Controlled Trial Comparative Study Clinical TrialDouble-blind comparative trial of oral ondansetron versus oral granisetron versus IV ondansetron in the prevention of nausea and vomiting associated with highly emetogenic preparative regimens prior to stem cell transplantation.
The optimal management of transplantation preparative regimen-induced nausea and vomiting remains unknown. We conducted a Phase III double-blind study to determine the efficacy and costs of oral ondansetron versus oral granisetron versus IV ondansetron and PRN rescue antiemetics for the prevention/control of nausea and vomiting associated with high-dose chemotherapy or chemoradiotherapy prior to stem cell transplantation. One hundred two patients were randomized to receive either 8 mg PO ondansetron every 8 hours, 1 mg PO granisetron every 12 hours, or 32 mg IV ondansetron every 24 hours plus 10 mg IV dexamethasone daily during and 1 day after the various preparative regimens. ⋯ None of the differences were statistically significant. A cost analysis revealed significant differences among all arms (P = .0001, all comparisons). All 3 regimens had similar efficacy in this BMT population; oral ondansetron was the most cost-effective.

Comparative StudyCD31 mismatching affects marrow transplantation outcome.
Graft-versus-host disease (GVHD) complicating allogeneic bone marrow transplantation (BMT) is often attributed to mismatched minor histocompatibility antigens (mHags), which are poorly defined in humans. CD31 is a candidate human mHag relevant to acute GVHD, but reports disagree about its level of significance, the role of HLA restriction, and the relative importance of different polymorphic codons within the molecule. We therefore examined in greater detail the impact of CD31-matching on BMT outcome in a prospective study from a single institution. ⋯ CD31 nonidentity showed a trend but failed to achieve statistical significance as a risk factor for relapse and for chronic GVHD. In conclusion, donor-recipient CD31 nonidentity is a significant risk factor for survival and for severe acute GVHD in HLA-identical sibling BMT. The stronger associations with codon 563/670 suggest that polymorphism may be more important than the linked polymorphism at codon 125.

Practice Guideline GuidelineGuidelines for preventing opportunistic infections among hematopoietic stem cell transplant recipients: focus on community respiratory virus infections.
Guidelines for preventing opportunistic infections among hematopoietic stem cell transplant (HSCT) recipients, cosponsored by the Centers for Disease Control and Prevention, the Infectious Diseases Society of America, and the American Society for Blood and Marrow Transplantation, were issued in October 2000. The guidelines recommend that to minimize transmission of community respiratory virus (CRV) infection, health care workers and visitors with symptoms of upper respiratory tract infection be restricted from having contact with HSCT recipients and candidates undergoing conditioning therapy. To screen HSCT recipients for CRVs, active clinical surveillance for CRV disease should be conducted on all hospitalized HSCT recipients and candidates undergoing conditioning therapy, including daily monitoring for signs and symptoms of CRV infections. ⋯ If test results are positive, the patient should be treated early and aggressively. Early preemptive therapy with such treatments as aerosolized ribavirin has been proposed, but limited data preclude a recommendation as to the optimal strategy. Lifelong seasonal influenza vaccination is recommended for all HSCT recipients.

Clinical TrialAllogeneic cell therapy for patients who relapse after autologous stem cell transplantation.
Allogeneic donor leukocytes can be used after nonmyeloablative conditioning to exploit their graft-versus-tumor (GVT) activity in the setting of reduced conditioning-regimen toxicity. This approach may be particularly useful for patients who relapse after autologous stem cell transplantation (SCT). However, GVT activity, toxicity, and ability to establish mixed chimerism may differ in patients who were heavily pretreated prior to SCT compared with patients treated earlier in the course of their disease. ⋯ However, these data show that ACT with either DLI or G-CSF-stimulated blood cells results in direct GVT activity in some patients with Hodgkin's disease, myeloma, and non-Hodgkin's lymphoma, even after relapse from autologous SCT. Most patients developed donor chimerism with minimal conditioning. Alternative prophylactic regimens that control GVHD while maintaining GVT are needed to improve outcomes in these heavily pretreated patients.

Clinical TrialRespiratory virus infections in stem cell transplant patients: the European experience.
The frequency of and survival from community-acquired respiratory virus (CRV) infections among patients undergoing allogeneic or autologous stem cell transplantation (SCT) were evaluated in a prospective study conducted at 37 medical centers affiliated with the European Group for Blood and Marrow Transplantation. Of the 40 CRV infections diagnosed in 1863 patients (739, allogeneic SCT; 1124, autologous SCT), 20 were attributed to respiratory syncytial virus (RSV), 4 to parainfluenza viruses, and 16 to influenza virus A. ⋯ In an 18-month extension, an additional 53 patients with CRV were identified. Results for the combined data were similar to those from the first phase of the study.
