OBJECTIVE: To investigate the relationship between semi-quantification of urine paraquat and the severity of acute paraquat poisoning, and to evaluate the prognostic value of the test in patients with acute paraquat poisoning.
METHODS: A total of 179 patients with acute paraquat poisoning were categorized into four groups according to their semi-quantification results of urine paraquat: +group (n = 36), ++group (n = 23), +++ group (n = 25), and ++++group (n = 95). The clinical features, severity of hepatic and renal injuries, respiratory failure, and clinical classification were compared between these four groups. Kaplan-Meier analysis was used to evaluate the survival rate.
RESULTS: The 60-day mortality was 45.25% (81/179). The amount of ingestion increased significantly from +group to ++++group (P < 0.05). No patient in +group was found to have serious complications, while most patients in ++++group suffered organ dysfunction or even organ failure. The incidence of acute respiratory failure, renal failure, and hepatic failure in ++++group was significantly higher than that in +group, ++group, and +++group (P < 0.05). The urine paraquat concentration was positively correlated with the clinical severity of acute paraquat poisoning (Spearman correlation coefficient = 0.720, P < 0.01). Kaplan-Meier survival analysis showed that the mortality of ++++group (73.7%) was significantly higher than that of +++group (40%), ++group (4.3%), and +group (0%) (P < 0.05).
CONCLUSION: The semi-quantification of urine paraquat is a promising test in evaluating the severity of acute paraquat poisoning. This test can be used to guide therapy and to predict the outcomes of patients suffering acute paraquat poisoning.
