Abstract

Survival after allogeneic stem cell transplantation (allo-HSCT) has improved, but so have long-term sequelae. We studied risk factors for fractures and impaired bone health in allo-HSCT patients in the Basel HSCT registry from 01/2003 to 12/2014 using cox proportional models adjusted for age, gender and Karnofsky Index. Our primary endpoint was the incidence of fractures. Out of 652 patients, 32 (5.0%) had a new fracture after transplantation (yearly incidence rate of 1.6%, 95% Confidence Interval [95%CI] 1.1-2.3%) and 325 (49.8%) had low bone mineral density (yearly incidence rate of 13.1%, 95%CI 11.6-14.8%), including 36.0% with osteopenia and 13.8% with osteoporosis. We found vitamin D deficiency during follow-up (Hazard Ratio [HR] 1.25, 95%CI 1.11-1.41, p < 0.001), hyperthyroidism before transplantation (HR 4.85, 95%CI 1.05-22.54, p = 0.044), cumulative years of immunosuppressant exposure (HR 1.23, 95%CI 1.07-1.41, p = 0.004 for steroidal and HR 1.09, 95%CI 1.01-1.18, p = 0.025 for non-steroidal drugs) and graft-versus-host disease (acute HR 1.24, 95%CI 1.11-1.40, p < 0.001; chronic HR 2.82, 95%CI 1.12-7.13, p = 0.028) to be significantly associated with fractures. Patients undergoing HSCT are at increased risk of fractures...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
