Abstract

Chronic graft-versus-host disease (cGVHD) is a common but serious complication of allogeneic haematopoietic stem cell transplantation (HSCT). Oral involvement of cGVHD occurs in 80 to 100% of patients suffering from cGVHD and may be the early manifestation of this complication. To study whether the histological changes of oral cGVHD are detectable in apparently normal oral mucosa of HSCT patients without clinical manifestations of the disease. This study enrolled 13 adult patients who underwent allogeneic HSCT for haematological malignancies. The presence of lichenoid, atrophic or erythematous changes of the oral mucosa detected on oral examination approximately 100 days after the HSCT was regarded as positive for cGVHD. An incisional biopsy of the oral mucosa was taken from patients with and without oral cGVHD and the specimens were examined by a pathologist who was unaware of the clinical state of the sampled mucosa. Biopsies were taken from four patients with clinical manifestations of oral cGVHD and from nine patients with apparently normal oral mucosa. Histological cGVHD changes were detected in each of the four patients (100%) with clinical manifestations of oral cGVHD and in six of the nine patients (66.6%) with apparent...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.
