BACKGROUND Burnout syndrome occurs frequently amongst oncology healthcare workers. It has a detrimental effect on the patient-physician relationship. Little is known about the prevalence and causes of burnout amongst junior doctors in oncology. METHODS An anonymous questionnaire was sent out to every medical or radiation oncology or haematology resident(More)
Clostridium difficile (C. difficile) infection was observed in 13% of recipients after hematopoietic stem cell transplantation (HSCT), mainly in the first month posttransplantation. Risk factors were cord blood as the source of stem cells, acute graft-versus-host disease (GVHD), and total body irradiation (TBI). No association was found with an increased(More)
BACKGROUND Thrombotic microangiopathy (TMA) occurring after allogeneic hematopoietic stem cell transplantation (HSCT) has a devastating prognosis. Response rates to current therapies (mainly plasma exchange) are unsatisfactory. Thrombotic microangiopathy after allogeneic HSCT shares similarities with atypical hemolytic uremic syndrome (aHUS) in the(More)
Incidence on relapse and nonrelapse mortality (NRM) of chronic graft-versus-host disease (GVHD), per National Institutes of Health (NIH) criteria, is not well defined after reduced-intensity conditioning (RIC) regimens. We analyzed the association of chronic GVHD with the risk of relapse and NRM using Cox models in 177 consecutive patients who underwent(More)
We conducted a nationwide retrospective study to evaluate clinical characteristics and outcome of mucormycosis among allogeneic haematopoietic stem cell transplant recipients. Twenty-nine patients were diagnosed between 2003 and 2008. Mucormycosis occurred at a median of 225 days after allogeneic haematopoietic stem cell transplant, and as a breakthrough(More)
Understanding the heterogeneity of human CD4+FOXP3+ regulatory T cells (Tregs) and their potential for lineage reprogramming is of critical importance for moving Treg therapy into the clinics. Using multiparameter single-cell analysis techniques, we explored the heterogeneity and functional diversity of human Tregs in healthy donors and in patients after(More)
Imatinib mesylate (IM), a tyrosine kinase inhibitor, has shown efficacy for the treatment of chronic GVHD (cGVHD),1-3 with overall response rates of fibrotic skin symptoms evaluated in 2 open-label studies ranging from 50%1 to 79%.2 To assess the global long-term effectiveness of IM for sclerodermatous cGVHD, we performed a retrospective study on 39(More)
Previous studies on regulatory T-cell (Treg) reconstitution after allogeneic hematopoietic SCT (HSCT) have suggested that, within the GVHD process, imbalance between effector T cells and Tregs may be more important than the absolute numbers of circulating Tregs. No study has analyzed naive vs memory Treg reconstitution in a longitudinal cohort with large(More)
Allogeneic hematopoietic stem cell transplantation provides the best chance of long-term survival for patients with AML, but is associated with an unpredictable risk of treatment-related mortality. From January 2000 to December 2010, we compared the outcomes for patients with AML aged 35 and over using reduced-intensity conditioning (RIC, N=60) or(More)
Diagnosis of gastrointestinal GVHD (GI-GVHD) is based on clinical symptoms and histologic findings. No biomarkers predicting responses to treatment are routinely available even though 30% to 50% of patients will not respond to corticosteroids. In this study, we aimed to evaluate fecal calprotectin, α-1-antitrypsin (α(1)-AT), and elastase at the time of(More)
