Changes in the ALT-LDH index over the first 5 days after admission. In most of the conservative survivors, a rapid elevation of the index was observed. Once the serum LDH activity reached the normal range (below 229 U/L), subsequent plotting was avoided. Two patients who had serum LDH within the normal range at admission are not included in the figure. On the contrary, the index decreased or remained constant in most of the patients who died before LT or underwent LT.
