Introduction: Multiple organ dysfunction syndrome (MODS) with secondary hemophagocytic lymphohistiocytosis (SHLH) causes significant mortality. We aimed to identify the predictor factors for death in pediatric patients with SHLH-associated MODS receiving continuous renal replacement therapy (CRRT).
Methods: This multicentered nested case-control study was conducted from 2016 to 2020. The characteristics were compared between survivors and non-survivors. Logistic regression was applied to identify the risk factors for death. The cutoff values were assessed by receiver operating characteristics curves.
Results: Fifty two patients were enrolled in this study. Interleukin-6 level (p = 0.018) and the number of organ dysfunction (p = 0.047) were independent risk factors for death. The cutoff value of 13.12 pg/ml interleukin-6 and three organs dysfunction at CRRT initiation presented a high sensitivity and specificity.
Conclusion: The number of organ dysfunction and interleukin-6 at CRRT initiation are independent risk factors for death in pediatric patients with SHLH-associated MODS.
