Selected AbstractsEORTC QLQ-C30 and FACT-BMT for the measurement of quality of life in bone marrow transplant recipients: a comparisonEUROPEAN JOURNAL OF HAEMATOLOGY, Issue 2 2000Martin Kopp Abstract: The purpose of the study was to compare two differentquality-of-life self-rating instruments, namely the EORTC QLQ-C30, developed by the quality-of-life study group of the European Organisation for Research and Treatment of Cancer, and the FACT-BMT (version 3), the Functional Assessment of Cancer Therapy , Bone Marrow Transplantation scale, which is the FACT-G(eneral measure) in combination with a module developed specifically for evaluating quality of life of bone marrow transplant (BMT) patients. Fifty-six BMT recipients completed both the EORTC QLQ-C30 and the FACT-BMT (German language version) during the same session. Questionnaire data were analyzed on a subscale basis using correlation analysis and multiple linear regression. Correlations between corresponding subscales of EORTC QLQ-C30 and the FACT-BMT ranged from r=0.30 for the emotional domain (poor agreement) to r=0.77 for global QOL (good agreement). This suggests that the instruments, despite considerable overlap, possibly focus on different aspects of QOL, in particular in addressing emotional and social issues of BMT patients. It appears that the FACT-BMT gives a more comprehensive overview regarding the multidimensional construct of quality of life. The EORTC QLQ-C30 gives more insight into the physical aspects of quality of life and helps to identify symptoms which effectively decrease quality of life from the patient's perspective. The QLQ-C30 might be improved by the incorporation of a BMT-specific module currently under development. We therefore conclude that neither of the two instruments can be replaced by the other in the assessment of QOL of BMT patients and that a direct comparison of results obtained with the two instruments is likely to be misleading. [source] Revaccination of bone marrow transplant recipients: a review of current practices in AustraliaINTERNAL MEDICINE JOURNAL, Issue 4 2009Adrienne Torda Abstract Background: Vaccination following bone marrow transplant (BMT) is an important part of ongoing care and disease prevention. The aim of the study was to investigate vaccination procedures in BMT recipients and identify what systems are in place throughout Australia to remind and alert patients concerning their need for vaccination. Methods: Questionnaires were sent to haematologists managing BMT recipients in Australia to examine post-BMT vaccination practices in hospitals and outpatient clinics. Questionnaires were also sent to BMT recipients in New South Wales, who had their transplants (either allogeneic or autologous) in the past 5 years to determine what vaccinations they had received and what vaccination reminder systems had been used. Results: Vaccine recommendations and practices by BMT physicians showed little consensus. They also differed greatly between autologous and allogeneic transplant recipients. Only just more than half of the physicians had an effective reminder system in place and only 12 of 34 patients had received vaccination reminders. One-third of all patients were not aware of any need for revaccination. Conclusion: The disparity in physician practice regarding revaccination is significant and may reflect the lack of data available regarding efficacy of revaccination in this setting and/or a lack of knowledge about recommendations. Because of this, a national immunization schedule for post-BMT patients founded on evidence-based studies is required to provide optimal patient care. The lack of effective follow up and reminder systems ensuring patient completion of vaccination schedules is also an area needing improvement. [source] Non-specific interstitial pneumonia as a manifestation of graft-versus-host disease following pediatric allogeneic hematopoietic stem cell transplantationPATHOLOGY INTERNATIONAL, Issue 2 2010Aya Miyagawa-Hayashino Bronchiolitis obliterans (BO) is generally believed to be a marker of pulmonary manifestation of graft-versus-host disease (GVHD) in patients who have undergone bone marrow transplantation for hematological malignancy. Pulmonary manifestations reported as GVHD (other than BO) include lymphocytic bronchiolitis with cellular interstitial pneumonia, lymphoid interstitial pneumonia, veno-occlusive disease, and diffuse alveolar damage. Morphological reactions in the lungs of bone marrow transplant recipients associated with interstitial pneumonia have not been described systematically. Reported herein is a fibrosing non-specific interstitial pneumonia (NSIP) pattern together with BO in both lungs in an 8-year-old girl following a second allogeneic hematopoietic stem cell transplantation for relapsed neuroblastoma of adrenal origin. The course was complicated by bilateral pneumothoraces, and the patient underwent lung transplantation 3 years after the second stem cell transplantation. Because the patient had chronic GVHD of the skin and the liver preceeded by the development of pulmonary involvement, NSIP may represent one of the facets of pulmonary GVHD. [source] HPLC-UV assay for monitoring total and unbound mycophenolic acid concentrations in childrenBIOMEDICAL CHROMATOGRAPHY, Issue 1 2009L. Zeng Abstract A simple, accurate and sensitive HPLC method was developed for measuring total and unbound mycophenolic acid (MPA) in human plasma. Total MPA was extracted by protein precipitation and ultrafiltration was used to assess unbound MPA concentrations. The supernatant (20 µL) or ultrafiltrate (100 µL) was injected onto a C18 HPLC column with a mobile phase of 0.05 m sodium phosphate buffer (pH 2.31),acetonitrile (55:45, v/v for total MPA; 50:50 for unbound MPA) with UV detection at 254 nm. The extraction recovery was over 93% and reproducible. The assay was linear over the concentration range of 0.07,50 mg/L for total MPA and 4,1500 µg/L for unbound MPA. Intra- and inter-day assay reproducibility was less than 10%. Detection limits were 0.04 mg/L and 2 µg/L for total and unbound MPA, respectively. The assay utility was established in samples collected from five paediatric bone marrow transplant recipients who were receiving intravenous doses of mycophenolate mofetil. In these patients MPA concentrations ranged from 0.07 to 7.83 mg/L and unbound drug concentrations ranged from 2.1 to 107.5 µg/L. This method can be effectively applied to MPA pharmacokinetics in paediatric patients. Copyright © 2008 John Wiley & Sons, Ltd. [source] | ||||||||||
