The analysis results showed that there were no significant differences between the death group and the survival group in the WBC, absolute number of neutrophils, hemoglobin, fibrinogen, LDH, ALT, TG, TBIL, PT, and APTT (p > 0.05), while the platelet and albumin levels of HLH patients in the death group were significantly lower than those of the survival group, the AST level was significantly higher than that of the survival group, and the differences were statistically significant (p < 0.05). This evidence concerns the gene ALB and hemophagocytic syndrome.
