Pneumonia remitted after a standard antibiotic therapy, but hypertransaminasemia and altered levels of other serum muscle breakdown enzymes persisted at several follow ups (AST up to 388 U/L, ALT up to 164 U/L, CPK up to 942 U/L, n.v. 30-135U/L, LDH up to 4851 U/l, n.v. 313–618 U/L). Here, GPT is linked to susceptibility to pneumonia measurement.
