Objective: The intoxications caused by 2,4-Dinitrophenol (2,4-DNP), even death, have been frequently reported in recent years. This study aims to investigate the dynamic changes of plasma toxin concentration and explore the clinical value of resin hemoperfusion (HP) in the treatment of patients with acute 2,4-DNP poisoning. Methods: We reported 16 cases of acute 2,4-DNP poisoning through occupational exposure due to ignoring the risk of poisoning. The blood samples were collected from the 14 survivors. According to the different treatments of resin HP, the survivors were divided into routine HP (n=5) and intensive HP (n=9) groups. Ultra high performance liquid chromatography/ tandem mass spectroscopy (UPLC-MS/MS) was used to detect the 2,4-DNP concentration in plasma in this study. Results: The 14 survivors recovered very well after treatment. The initial plasma 2,4-DNP concentrations (C1) of survivors ranged from 0.25 to 41.88 µg/ml (mean (12.56±13.93) µg/ml). A positive correlation existed between initial plasma 2,4-DNP concentration (C1) and temperature. The elimination of 2,4-DNP was slow and persistent, and the total clearance rates of plasma toxin from the 1st to 3rd day (R3), the 3rd to 7th day (R3&#x2013;7), and the 1st to 7th day (R7), were only (53.03±14.04)%, (55.25±10.50)%, and (78.29±10.22)%, respectively. The plasma toxin was cleared up to 25 d after poisoning in most of the patients. The R3, R3&#x2013;7, and R7 in the intensive HP group were all apparently higher than those in the routine HP group, with statistical significance (P<0.05). Simultaneously, the elimination half-life (t1/2) of 2,4-DNP in the intensive HP group was apparently shorter than that in the routine HP group, with statistical significance (P<0.05). Conclusions: The clinicians should be aware of this slow and persistent process in the elimination of plasma 2,4-DNP. Higher initial plasma toxin concentration resulted in a more severe fever for the patient. According to the limited data, longer and more frequent resin HP may accelerate to eliminate the poison.


结论:14例幸存患者的初始血浆2,4-二硝基苯酚浓度为0.25~41.88 µg/ml不等,且初始血浆毒物浓度与患者体温高低呈正相关。研究发现,机体对于2,4-二硝基苯酚的清除是缓慢而持久的。根据血浆 2,4-二硝基苯酚浓度动态变化计算而得,患者血浆毒物总清除率R3(中毒后第1日至第3日)、R3-7(中毒后第3日至第7日)和R7(中毒后第1日至第7日)分别为(53.03±14.04)%、(55.2±10.50)% 和 (78.29±10.22)%。其中,强化血液灌流组患者的血浆毒物总清除率R3R3-7R7均显著高于常规血液灌流组,差异有统计学意义(P<0.05)。此外,强化血液灌流组患者的 2,4-二硝基苯酚清除半衰期(t1/2)明显短于常规血液灌流组,差异有统计学意义(P<0.05)。因而,本研究显示高强度、高频度地实施血液灌流治疗有利于急性2,4-二硝基苯酚中毒患者清除毒物。
