Disease of the liver following bone marrow transplantation in children: incidence, clinical course and outcome in a long-term perspective.

Abstract

Sixty-four consecutive cases of allogeneic (n = 16), autologous (n = 47) or syngeneic (n = 1) bone marrow transplantation (BMT) in children with haematological or lymphoid malignancy, aplasia or metabolic disease were reviewed to assess the incidence, clinical presentation and outcome of liver disease. Median follow-up time was 5 y (1.0-10). No liver diagnosis was established at the pre-transplant check-up. During the first 100 d post-transplant, 81% of the patients had impaired liver function as documented by various biochemical parameters. Three of 64 patients (5%) met diagnostic criteria for veno-occlusive disease. Four (25%) of the 16 receiving allografts were diagnosed as having acute graft vs host disease (GVHD) with liver involvement (grades II-III). No patient died of liver disease. During the late post-transplant follow-up, one patient developed HCV hepatitis after packed erythrocyte transfusion. Four patients were diagnosed as having chronic GVHD with liver involvement; three of them also had an episode of CMV hepatitis. At their latest follow-up, the patients with chronic GVHD had aminotransferase values 1.5-3 times the normal, whereas all other long-term survivors had normal or near-normal liver function tests. We conclude that the incidence of serious liver disease was low in this paediatric population of bone marrow recipients.
