Abstrakt: Background: Aluminum phosphides (AlP) is a solid fumigant pesticide known for its high toxicity and mortality. Diagnosis of AlP is based on the history and clinical examination. The literature on the early prediction of adverse outcomes following AlP exposure is limited. Therefore, the current study aimed to investigate the role of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte Ratio (PLR) as early accessible predictors of mortality in AlP-exposed patients.
Method: We conducted a retrospective cross-sectional study on 420 adult patients with acute AlP poisoning.
Results: This study reported mean NLR and PLR of 4.07 ± 3.82 and 182.97 ± 147.29, respectively. Patients with high NLR and PLR showed more severe presentation, indicated by the significantly lower Glasgow scales and higher poison severity score grades. Besides, the need for mechanical ventilation, vasopressor therapy, and ICU admission was significantly higher among patients with high NLR and PLR ( P  = 0.000). We observed a significantly higher proportion of mortality among patients with high NLR (69.5%) and PLR (87.4%) ( P  = 0.000). The NLR > 3.42, PLR > 172.5, and their combinations were significant predictors of mortality, showing area under curves above 0.94. Utilizing a combination of NLR and PLR yielded a modestly improved performance as a mortality predictor with a slight increase in the Youden index (0.81). The high NLR and high PLR groups had mean survival times of 28.851 and 16.256 h respectively.
Conclusion: These findings suggest that high NLR and PLR are associated with a worse prognosis and a higher mortality risk among patients with acute AlP poisoning.
