Abstract:
Objective:To investigate the clinical features and risk factors of multiple organ dysfunction syndrome (MODS) caused by wasp sting.Methods:A retrospective cohort study was conducted to collect the general data of wasp sting patients who had a clear history of wasp sting disease and clinical manifestations from June 2016 to December 2020 and were first diagnosed as wasp sting in hospital. Patients with hematological diseases, malignant tumors, severe liver and kidney dysfunction, cardiac insufficiency, and patients who had received hormone therapy before admission were excluded. Patients who were unable to obtain effective laboratory results due to hemolysis or other reasons within 48 h of admission were also excluded. The white blood cell count (WBC), neutrophil count (NEU), lymphocyte count (LYM), hemoglobin count (HB), myoglobin (Mb/MYO), activated partial thromboplastin time (APTT), albumin (ALB), K, Na, and Cl of the blood samples collected within 48 h after admission were recorded. Patients were divided into the MODS group and non-MODS group according to whether MODS occurred during hospitalization. Uni- and multivariate analysis were used to analyze the factors affecting the occurrence of MODS in wasp sting patients during hospitalization, and the receiver operating characteristic (ROC) curve was plotted to evaluate the predictive effect of myoglobin level on the occurrence of MODS in wasp sting patients during hospitalization.Results:Mb, WBC, NEU, APTT and serum potassium in the MODS group [3890.00 (1416.90-4057.00) ng/mL, (21.99 ± 8.18) × 10 9/L, (19.61 ± 7.33)× 10 9/L, (93.75 ± 45.77) s, and (4.99 ± 0.95) mmol/L] were significantly higher than those in the non-MODS group [73.50 (34.30-264.20) ng/mL, (13.40 ± 4.14)× 10 9/L, (11.18±4.73)× 10 9/L, (37.00 ± 17.16) s, and (4.05 ± 0.56) mmol/L] (all P < 0.05); blood chlorine and ALB [(101.50 (98.25-105.00) mmol/L and (35.36 ± 6.44) g/L)] were significantly lower than those in the non-MODS group [(105.00 (103.00-107.00) mmol/L and (40.71 ± 5.48) g/L)] (all P < 0.05). Multivariate logistic regression analysis showed that NEU ( OR = 0.729, 95% CI: 0.542~0.981), Mb ( OR = 0.999, 95% CI: 0.998~1.000), and APTT ( OR = 0.951, 95% CI: 0.921~0.982) were independent risk factors for MODS in wasp sting patients. ROC curve analysis showed that NEU, Mb and APTT could be used to evaluate the occurrence of MODS in wasp sting patients. Among them, Mb had the highest predictive value (AUC = 0.950, 95 % CI: 0.891~0.982). The optimal cutoff value of Mb for predicting the occurrence of MODS in wasp sting patients was 515.30 ng/mL, and the corresponding sensitivity and specificity were 90.62% and 87.23%, respectively. Conclusion:Mb is an independent risk factor for MODS in wasp sting patients, which can be used as a good predictor of MODS in wasp sting patients.
