We prospectively compared outcomes after a fludarabine (Flu) plus oral busulfan (Bu)-containing reduced-intensity conditioning regimen (150 mg/m2 Flu and 10 mg/kg oral Bu), with (n = 32; Flu- T Bu group) or without (n = 30; Flu-Bu group) therapeutic dose monitoring and dose adjustment of Bu. All patients received peripheral blood stem cells from a genoidentical sibling, and study cohorts had similar patient characteristics. Dose adjustments of Bu were required in 20 (63%) patients in the Flu- T Bu group (median final dose, 8.

Background: Most studies indicate that ABO incompatibility has no effect on the clinical outcome after allogeneic peripheral blood progenitor cell (PBPC) transplantation (allo-PBPCT). However, it carries additional risks of hemolytic reactions, delayed red blood cell (RBC) engraftment, and pure red cell aplasia (PRCA). Data on these events after reduced intensity conditioning (RIC) regimens are limited, but recent studies have suggested a higher transplant-related mortality (TRM) and morbidity in this setting.

We evaluated prognostic factors of melphalan/fludarabine-based dose-reduced allografts in patients with multiple myeloma. From 1998 to 2002, 120 patients with multiple myeloma were treated with melphalan/fludarabine followed by allogeneic stem cell transplantation. The cumulative risk at 1 year for treatment-related mortality (TRM) was 18% (95% confidence interval [CI], 12%-28%).

Myeloablative allogeneic hematopoietic stem cell transplantation (allo-HSCT) is increasingly used in patients with lymphoma who experience disease relapse after autologous hematopoietic stem cell transplantation (auto-HSCT) because the allograft is tumor free and may induce a graft-versus-tumor effect. We analyzed 114 patients treated with this approach from 1990 to 1999 to assess disease progression, progression-free survival (PFS), and overall survival (OS). Cumulative incidence of disease progression at 3 years was 52%, whereas treatment-related mortality was 22%, lower than previously reported.

Amphotericin B Lipid Complex (ABLC) was the first lipid-based formulation of amphotericin B (AmB) to be developed, it was designed to provide a less toxic alternative to conventional AmB without compromising efficacy. Preclinical and early clinical data relating to ABLC have been presented in previous reviews. This paper reviews more recent published data on the efficacy, safety and cost-effectiveness of ABLC.

Background: Conventional amphotericin B (c-AmB) remains the empirical antifungal treatment of choice for neutropenic patients with persistent fever of unknown origin (FUO). Unfortunately, empirical treatment with c-AmB is hampered by its safety profile, with frequent infusion-related adverse events (IRAEs) and renal toxicity. Amphotericin B lipid complex (ABLC) has been investigated for this indication due to its low toxicity profile.

Objectives: The aim of this study was to compare two approaches used to reduce transplant-related mortality (TRM) after allogeneic peripheral blood stem cell transplantation (allo-PBSCT) in elderly patients.

Patients And Methods: Data from 50 patients, 45 years of age or older, consecutively treated with an HLA-identical sibling allo-PBSCT at the Hospital de Sant Pau were analyzed. We have compared the outcome of patients treated with conventional myeloablative regimens and CD34(+)-selected cells (CD34(+) group; n=23) with those receiving reduced-intensity conditioning regimens, consisting of fludarabine (150 mg/m(2)) plus an alkylating agent, followed by unmanipulated grafts (RIC group; n=27).

In this article, we report on 904 patients undergoing transplantation for follicular lymphoma. A total of 176 (19%) received allogeneic, 131 (14%) received purged autologous, and 597 (67%) received unpurged autologous transplants. Five-year treatment-related mortality (TRM) rates were 30%, 14%, and 8% and 5-year recurrence rates were 21%, 43%, and 58% after allotransplantation, purged autotransplantation, and unpurged autotransplantation, respectively.

Background And Objectives: The International Prognostic Index (IPI), initially designed for aggressive lymphomas, has been successfully used in patients with follicular lymphoma (FL). The Italian Lymphoma Intergroup (ILI) created a new prognostic index specific for FL. The aim of this study was to compare which of these two indices is more useful when applied to a large group of FL patients.

We studied the association between CD34 cell dose and transplant outcomes in 359 bone marrow (BM) and 511 peripheral blood stem cell (PBSC) transplant recipients from human leucocyte antigen (HLA)-identical siblings, reported to the International Bone Marrow Transplant Registry (IBMTR). Transplants for leukaemia were performed between 1995 and 1998. Patients were divided into those receiving below or above the median CD34+ dose, for BM (3 x 106/kg) and PBSC (6 x 106/kg) grafts respectively.

Background And Objectives: Patients over 60 years are frequently excluded from autologous stem cell transplantation (ASCT) programs due to a traditionally high rate of transplant-related mortality (TRM) in such indications. We evaluated the results of ASCT in a group of 49 patients >= 60 years of age [32 males, median age 63 years (range, 60 to 71)] autografted in our institution from January 1995 to December 2001.

Design And Methods: There were 27 patients with multiple myeloma, 13 with non-Hodgkin's lymphoma, 3 with acute myelogenous leukemia, 3 with chronic myelogenous leukemia and 3 with other hematological malignancies.

During a 2-year period, 157 consecutive episodes of respiratory virus infections that occurred in 130 patients with upper or lower respiratory tract infection were analyzed for respiratory viruses. A respiratory virus was identified in 75 episodes (48%), and several viruses were found in 13 episodes: there were a total of 56 influenza A virus infections, 14 respiratory syncytial virus infections, 8 adenovirus infections, 8 infections with parainfluenza virus types 1 or 3, and 7 enterovirus infections. On multivariate analysis, the only variable that predicted progression to pneumonia in patients with an upper respiratory tract infection was the presence of respiratory syncytial virus, whereas lymphocytopenia had a nonsignificant trend.

Although nonmyeloablative conditioning regimen transplantations (NMTs) induce engraftment of allogeneic stem cells with a low spectrum of toxicity, graft-versus-host disease (GVHD) remains a significant cause of morbidity and mortality. In vivo T-cell depletion, using alemtuzumab, has been shown to reduce the incidence of GVHD. However, this type of maneuver, although reducing GVHD, may have an adverse impact on disease response, because NMTs exhibit their antitumor activity by relying on a graft-versus-malignancy effect.
