Objectives Patients with systemic lupus erythematosus (SLE) refractory to conventional immunosuppression suffer substantial morbidity and mortality due active disease treatment toxicity. Immunoablation followed by autologous stem cell transplantation (ASCT) is a novel therapeutic strategy that potentially offers new hope these patients. Methods This retrospective survey reviews the efficacy safety of ASCT in 28 SLE patients from eight centres reported European Group for Blood Marrow...

Regimen-related mucosal toxicity is extremely common following cytotoxic chemotherapy and radiotherapy. Mucositis as an important determinant of the inflammatory response infectious complications in cancer treated patients. Most assessment scales for damage are focussed on oral mucositis, since it easy to evaluate. Measuring gastrointestinal musocal objectively remains difficult because cannot be seen directly or readily detected. One potential non-invasive biomarkers plasma citrulline...

Recent developments in the field of targeted therapy have led to discovery a new drug, plerixafor, that is specific inhibitor CXCR4 receptor. Plerixafor acts concert with granulocyte colony-stimulating factor (G-CSF) increase number stem cells circulating peripheral blood (PB). Therefore, it has been applied hematopoietic cell mobilization. We analyzed retrospectively data regarding mobilization plerixafor cohort 61 patients suffering from multiple myeloma (N = 23), non-Hodgkin's lymphoma...
