ABSTRACT
Background. Acute liver failure (ALF) is a rare but potentially life-threatening condition and liver transplantation
(LTX) remains frequently the only effective therapy. Nevertheless, some patients recover without
LTX but the individual indication for or against LTX remains difficult.
Aim. To evaluate maximal liver function
capacity (LiMAx) for predicting the prognosis of ALF.
Material and methods. Clinic data of 12 patients
was retrospectively analyzed to compare the different liver function test results with the patients’ clinical
outcome. Patients were assessed by the LiMAx test, a non-invasive breath test determining cytochrome
P450 1A2 capacity using intravenous 13C-methacetin. Statistical analysis compared patients with spontaneous
recovery versus non-recovery (LTX or death).
Results. Twelve patients (6 male, 6 female; 49 [11-72]
years) with viral hepatitis (n = 2), toxic liver injury (n = 3), or cryptogenic liver failure (n = 7) were analyzed.
Seven patients fully recovered from ALF and were discharged without LTX. Three patients died and
two underwent LTX. The King’s College Criteria (KCC) was fulfilled in only one out of five patients without
recovery. The LiMAx was 19 ± 19 (16-62) for non-recovery
vs. 94 ± 119 (39-378) µ g/kg/h for recovery (P =
0.018). In contrast, all biochemical parameters [bilirubin (P = 0.106), creatinine (P = 0.343), AST (P = 0.53),
ALT (P = 0.876) and INR (P = 0.876) were statistically indistinct. Also the Model for End-Stage Liver Disease
(MELD) score did not show a difference [35 ± 4.3 (29-40)
vs. 30 ± 11.5 (6-40); P = 0.27].
Conclusions. Maximal
liver function capacity determined by LiMAx test is severely impaired in patients with ALF. The LiMAx test
might be effective in predicting the individual prognosis and the need for LTX in ALF.
