Compared to the active sJIA group, the platelet count, erythrocyte sedimentation rate (ESR), and fibrinogen levels in the sJIA-MAS group were significantly decreased (P < 0.05), whereas the ferritin, ferritin/ESR, aspartate aminotransferase (AST), alanine aminotransferase (ALT), sodium lactate dehydrogenase, and D-dimer levels were significantly increased (P < 0.05) (Table 3). This evidence concerns the gene GPT and macrophage activation syndrome.
