Abstract |
We described and analyzed the treatment process of an HIV-positive patient with severe paraquat (PQ) poisoning.A 34-year-old man ingested about 50 mL of a 20% solution of PQ in a suicide attempt. He was treated with gastric lavage, oral administration of adsorbent, and symptomatic treatments at the local hospital, and was transferred to our emergency department. Ten hours after the exposure, the concentration of plasma PQ was 2.17 mg/L and was substantially above the survival limits of the severity index for PQ poisoning (SIPP) curve (0.30 mg/L). The equation produced by Jones et al (Jones AL, Elton R, Flanagan R. Multiple logistic regression analysis of plasma paraquat concentrations as a predictor of outcome in 375 cases of paraquat poisoning. QJM. 1999:92;573-578) predicted a 20.5% probability of survival at admission. Unfortunately, the patient was diagnosed as HIV infected, and CD4 lymphocyte count also confirmed that the patient was in a state of mild suppression of immunological function.Immediately, the patient received normative immunosuppressive therapy and hemoperfusion (HP). On the 15th day after poisoning, the patient recovered well and was discharged.All along, the evolution of the patient's status was in accordance with the characteristics of PQ poisoning, but the extent and duration of damage was mismatching and drastically alleviative by the previous biological indices. The particular case of treatment may be indirectly supporting the effectiveness of immunosuppressive therapy in treating patients with PQ poisoning. Language: en |
