The data of plasma paraquat, CRP level and arterial blood gas were analyzed. Cox regression analysis was applied to evaluate the risk factors of prognosis. Receiver operating characteristics curve analysis and area under curve were used to calculate the predictive power of significant variable. Differences in patient survival were determined using the Kaplan–Meier method and a log-rank test.Results: Plasma CRP level was significantly increased in non-survival patients compared with survival patients(P < 0.05), and positively correlated with plasma paraquat level(P < 0.05). Cox regression analysis revealed that plasma CRP level was an independent prognostic marker of mortality within 30 days. The receiver operating characteristics curve analysis indicated that area under curve of plasma CRP level was0.867(95% CI: 0.81–0.93), and the cut-off value was 18 mg/L, and patients with CRP level over this value had a poor survival time compared with those with less than this value.Conclusions: These results suggest that plasma CRP level is distinct increased in patients with paraquat poisoning, and the plasma CRP level may be useful for the prediction of prognosis in paraquat poisoning.展开更多

The variables included: Demographic data, medical assessment, therapeutic options, laboratory findings, and the outcomes. Data were analyzed using SPSS, version 22. Significant difference between groups was tested using t-test for continues outcomes and χ~2 test for categorical. The significance level was considered to be P < 0.05. RESULTS A total of 104 patients(66.3% male) were evaluated. The mean age of the female patients was 22.81 ± 9.87 years and the male patients' was 27.21 ± 11.06 years. Ninety seven(93.3%) of all the cases were suicide attempts with mortality rate of 43.2%. Despite the necessity for emergency hemodialysis during the first 6 h of intoxication, none of the patients had dialysis during this time. Immunosuppressive and corticosteroid medications were not administrated in adequate dosage in 31.1% and 60% of the patients, respectively. Ingestion of more than22.5 cc of paraquat and increase in creatinine level were the most important predictors of mortality.CONCLUSION Treatment should start immediately for these patients.Moreover, creating a clinical guideline according to the findings can have an impact on the treatment procedure which seems to be necessary.展开更多
