Abstract

Central venulitis (CV), a distinct histologic lesion described in adult liver transplants, can occur with acute portal tract rejection or in isolation (ICV). Possible etiologies include immunosuppressive drug toxicity, acute cellular rejection, viral hepatitis, ischemic injury, and recurrent disease. This study was designed to characterize ICV and to assess its potential etiology in pediatric liver recipients because this population generally does not develop recurrent disease or viral hepatitis. All posttransplantation liver biopsy specimens that were obtained from children who received liver allografts over a 4-year period were reviewed. ICV was identified in 12 of 127 posttransplantation biopsies and in 7 of 45 allograft recipients. Only 4 liver transplantations were performed for potentially recurrent diseases (primary sclerosing cholangitis). ICV first appeared in posttransplantation biopsy specimens significantly later than did portal rejection alone. The finding of CV was not significantly correlated with elevation of Tacrolimus levels, reason for transplantation, donor/recipient cytomegalovirus (CMV) status or blood type, cold ischemic times, or the incidence of outflow obstruction. The responses of CV to therapy were v...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.
