Functional evaluation indicates physical losses after hematopoietic stem cell transplantation.

OBJECTIVE: To perform a function evaluation of patients before and after hematopoietic stem cell transplantation. METHODS: From November 2008 to November 2010, 29 female (58%) and 21 male patients (42%) with median age of 48 years (range: 24-67) were enrolled in this study. Data collection was performed before and after autologous or allogeneic hematopoietic stem cell transplantation. Evaluation instruments included the 2-minute walking test to evaluate gait performance with assessment of the oxygen saturation, heart rate and Borg Scale before and after the test; grip strength for strength evaluation, Schober Test for spine mobility testing and maximum and adapted activity scores of the Human Activity Profile questionnaire to test functionality in daily activities. RESULTS: Fifty patients were evaluated at baseline; six did not undergo hematopoietic stem cell transplantation (three died, one refused and two were excluded). Thus 44/50 (88% - 21 allogeneic and 23 autologous) transplantations were performed. Only 33 of the 44 patients (75%) performed evaluations after transplantation (nine died and two were excluded). Of the patients who performed both evaluations, significantly lower values were found in the evaluation after transplantation for the 2-minute walking test (p-value = 0.004), grip strength of both right and left hands (p-value = 0.004 and p-value < 0.0001, respectively), the Schober Test, and maximum and adapted activity scores (p-value < 0.0001). The heart rate was higher (p-value = 0.01) before the 2-minute walking test and oxygen saturation was higher (p-value = 0.02) after. CONCLUSION: Statistical differences indicate functional impairment after transplantation showing physical losses in this population.

Brazilian workshop model to train investigators in chronic graft-versus-host disease clinical trials according to the 2005-2006 National Institutes of Health recommendations.

BACKGROUND: The lack of standardization of clinical diagnostic criteria, classification and severity scores of chronic graft-versus-host disease led the National Institutes of Health to propose consensus criteria for the purpose of clinical trials. METHOD: Here we describe a one-day workshop model conducted by the Chronic Graft-versus-Host Disease Brazil-Seattle Consortium Study Group to train investigators interested in participating in multicenter clinical trials in Brazil. Workshop participants included eight transplant physicians, one dermatologist, two dentists, three physical therapists and one psychologist from five institutions. Workshop participants evaluated nine patients with varying degrees of severity of mucocutaneous lesions and other manifestations of the disease followed by a training session to review and discuss the issues encountered with the evaluation and scoring of patients and in the methods used to evaluate grip strength and the 2-minute walk test. RESULTS: Most participants had difficulties in rating the percentage of each type of mucocutaneous lesion and thought 20 minutes was insufficient to evaluate and record the scores of each patient using the National Institutes of Health criteria and other cutaneous assessments. Several specific areas of difficulties encountered by the evaluators were: 1) determining the percentage of erythema in movable and non-movable sclerosis, 2) whether to score all cutaneous findings in a particular area or just the dominant lesion; 3) clarification of the definition of poikiloderma in chronic graft-versus-host disease; 4) discrepant interpretation of the mouth score and 5) clarification on the methodology used for the evaluation of grip strength and the 2-minute walk tests. CONCLUSIONS: Results of this workshop support the need to train investigators participating in clinical trials on chronic graft-versus-host disease.
