Abstract

Patients who undergo allogeneic hematopoietic stem cell transplantation (allo-HSCT) can experience musculoskeletal pains in their lower limbs in the early and late post-transplantation period. This study investigated demographics and clinical characteristics of the lower limb pain (LLP) among Japanese survivors of pediatric allo-HSCT. A total of 143 consecutive Japanese patients who had undergone allo-HSCT less than 18 years of age in a single institute between 2005 and 2015 were reviewed. Patients referred for in-house orthopedic evaluation of their sustained LLPs that impaired ambulation were defined as LLP group. Illness/transplantation-related parameters were compared between LLP group and non-LLP group. Ninety children with a mean age of 8.5 years at transplantation were enrolled. Their median follow-up period following transplantation was 6.3 years (range, 2.1-12.5). There were four patients in LLP group, whose etiologies were AVN of the femoral head and insufficiency fracture (ISF) of the tibia or the medial cuneiform bone. Cumulative dose of steroids that administered from six months before transplantation to six months after discharge from hospitalization for transplantation was significantly higher in LLP group than n...Continue Reading

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.

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.
