Investigating Clinical Factors Influencing Pulmonary Fibrosis in Acute Diquat Poisoning

Abstract

Objective This study aimed to explore the factors influencing pulmonary fibrosis in patients with acute diquat poisoning through logistic regression analysis. Methods A retrospective analysis was conducted on 68 cases of acute diquat poisoning due to suicidal intent admitted to our hospital from February 2020 to March 2023. Patients were divided into a combined group (28 cases with pulmonary fibrosis) and an acute diquat poisoning group (40 cases without). A healthy control group consisted of 40 individuals. General data were compared among the three groups, and laboratory indicators were analyzed. Single and multiple logistic regression analyses were performed to identify risk factors for pulmonary fibrosis. Results There were no significant differences in gender, age, BMI, poisoning status, or treatment timing among the groups (P > 0.05). The combined group had significantly higher diquat ingestion dose, SIRS score, SOFA score, and APACHE II score compared to the poisoning group (P < 0.05). In the acute poisoning group, these scores were also higher than in the healthy controls (P < 0.05). Laboratory indicators, including Hb, PLT, ALP, DBil, ALB, BUN, Glu, BNP, and pH, showed no significant differences (P > 0.05). However, WBC, ALT, TBil, DBil, Cr, K+, Tn I, and Lac levels were significantly higher in the combined group compared to the acute poisoning group (P < 0.05). Logistic regression analysis identified factors influencing pulmonary fibrosis as diquat ingestion dose, K+, ALT, PaO2, Lac, and HCO3-. Conclusion The factors influencing pulmonary fibrosis in acute diquat poisoning include diquat ingestion dose, K+, ALT, PaO2, Lac, and HCO3-. These findings enhance understanding of pulmonary fibrosis pathogenesis and may inform clinical management for affected patients.
