Abstract

To determine the role of abdominal CT in assessment of severity and prognosis of patients with acute gastrointestinal (GI) graft-vs-host disease (GVHD). During 2000-2004, 41 patients with a clinical diagnosis of acute GI-GVHD were evaluated. CTs were examined for intestinal and extra-intestinal abnormalities, and correlated with clinical staging and outcome. 20 patients had GVHD clinical Stage I-II and 21 had Stage III-IV. 39 (95%) had abnormal CT appearances. The most consistent finding was bowel wall thickening: small (n=14, 34%) or large (n=5, 12%) bowel, or both (n=20, 49%). Other manifestations included bowel dilatation (n=7, 17%), mucosal enhancement (n=6, 15%) and gastric wall thickening (n=9, 38%). Extra-intestinal findings included mesenteric stranding (n=25, 61%), ascites (n=17, 41%), biliary abnormalities (n=12, 29%) and urinary excretion of orally administered gastrografin (n=12, 44%). Diffuse small-bowel thickening and any involvement of the large bowel were associated with severe clinical presentation. Diffuse small-bowel disease correlated with poor prognosis. 8 of 21 patients responded to therapy, compared with 15 of 20 patients with other patterns (p=0.02), and the cumulative incidence of GVHD-related death was...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.
