Evolution in the management of acute liver failure-associated aplastic anaemia in children: A single centre experience

Background/Aims Bone marrow failure (BMF) is a potentially life-threatening complication of acute liver failure (ALF). Methods To investigate prevalence and evolving management of BMF associated with ALF, we reviewed all cases seen in our centre over 17 years. BMF was classified as: (a) bone marrow hypoplasia, (b) severe aplastic anaemia (SAA) and (c) very severe aplastic anaemia (VSAA), using standard criteria. We compared outcomes in children receiving: (1) medical treatment only with or without immunomodulation (anti-lymphocyte globulin, calcineurin inhibitors, G-CSF); (2) medical treatment with or without immunomodulation plus liver transplantation (LT); (3) haematopoietic stem cell transplantation (HSCT). Results Of 213 patients with ALF, 20 [(9.4%); 14 (70%) boys] developed BMF after a median of 1 month (range, 0.5 to 7). Seven had VSAA, 7 SAA and 6 bone marrow hypoplasia. Five children were treated medically, including 3 by immunomodulation; 10 (50%) received LT, with immunomodulation in 6; 5 (25%) received HSCT, in one after LT. Four (20%) children died, only one as consequence of AA. There was no difference in recovery, complication rates or outcome among the three groups. Conclusions Aggressive management of ALF-associated AA, including immunomodulation, HSCT and LT, is successful in most cases. HSCT has the advantage of removing the risk of late clonal disorders.
