Systemic Immune-Inflammatory Index and Systemic Inflammatory Response Index in the Assessment of Multiple Organ Dysfunction Syndrome Caused by Wasp Stings.

Objective: This study aims to assess the prognosis of patients with multiple organ dysfunction syndrome (MODS) caused by wasp stings by analyzing early systemic immune inflammation index (SII) and systemic inflammation response index (SIRI) values. Methods: A retrospective analysis was conducted on 151 patients admitted to the Department of Emergency Medicine, Taihe Hospital, Hubei University of Medicine, from January 2019 to December 2023. Among them, 60 patients developed MODS and 91 patients did not (non-MODS group). Early peripheral blood cell count-derived inflammation indices such as white blood cell count, platelet count, absolute neutrophil value, absolute lymphocyte value, absolute monocyte value, NLR, SII, and SIRI, along with baseline demographics, were compared between the two groups. Logistic regression analyses were performed, and the predictive accuracy of SII and SIRI was evaluated using receiver operating characteristic (ROC) curves, with the area under the curve (AUC) used to quantify sensitivity. Results: Significant differences were observed between the non-MODS and MODS groups in terms of age, hospitalization duration, number of stings, APACHE II score, time to first medical visit, SII, and SIRI (P < 0.05). Logistic regression analysis confirmed that both SII and SIRI were significant predictors of prognosis (P < 0.05). The AUC for SII and SIRI were 0.776 and 0.853, respectively, indicating their predictive value. Conclusion: Elevations in SII and SIRI are associated with the severity of wasp sting injuries, and early SII and SIRI values can serve as prognostic indicators for predicting MODS development and mortality in wasp sting patients.
