Laboratory results were consistent with septic shock and multi-organ dysfunction: WBC 6.5 × 109/L, platelets 24 × 109/L, hemoglobin 93 g/L; procalcitonin 28.26 ng/mL, C-reactive protein 52.4 mg/L, interleukin-6 (IL-6) > 5000 pg/mL; arterial blood gas showed pH 7.32, HCO3– 14.7 mmol/L, and lactate 19 mmol/L. Here, IL6 is linked to septic shock.
