[Liver dysfunction in recipients of hematopoietic stem cells. Impact on mortality].
Liver disease is a well-known cause of early morbidity and mortality affecting 80% of patients receiving allogeneic bone-marrow transplantation (BMT). Drug toxicity, veno-occlusive disease (VOD), acute graft-versus-host disease (GVHD), and fungal, bacterial, and viral infections are the most frequent hepatic complications during this period. The aim of this retrospective study was to determine the prevalence and etiology of liver disease and its impact on mortality as well as to assess the predictive value of pre BMT hepatic biochemical tests on the subsequent occurrence of acute and/or chronic GVHD and patient mortality. Of a total of 236 patients who underwent allogeneic BMT, 82 were analysed. Liver dysfunction was found in 88%. The causes of liver disease were: acute GVHD, 40.2%; chronic GVHD, 15.9%; unknown, 9.8%; sepsis, 7.3%; hepatotoxicity, 6.1%; VOD, 3.7%; acute hepatitis and disease recurrence, 2.4%. The mortality rate was 37%. We found acute liver failure (ALF) in 10% of the deaths (8 patients). The causes of ALF in these cases were acute GVHD progression in 5, herpetic hepatitis in 1, disease recurrence in 1, and VOD in 1. The correlation coefficients indicating positive predictive values of pre BMT hepatic biochemical tests for the subsequent occurrence of acute GVHD, chronic GVHD, and mortality were 0.27, 0.14, and 0.43, respectively. There was no significant difference between patients with abnormal or normal pre BMT liver function tests in the frequency of acute and chronic GVHD or mortality.
