Paraquat and diquat are classified as bipyridyl compounds not only leads to acute organ damage, but also to a variety of complications. Patients with severe paraquat-induced poisoning may succumb to multiple organ failure involving the circulatory and respiratory systems. Deliberate self-poisoning with paraquat continues to be a major public health concern in many developing countries. At present there is no specific antidote to paraquat poisoning, hence the need to more focus on prevention and in cases of poisoning aggressive decontamination to prevent further absorption...

Paraquat is a fatal herbicide following acute exposure. Previous studies have suggested that multidrug resistance protein 1 (MDR1) might help remove paraquat from the lungs and the kidney. MDR1 single-nucleotide polymorphisms (SNPs) are involved in the pharmacokinetics of many drugs. The purpose of this study was to determine whether MDR1 SNPs were associated with the mortality in paraquat intoxicated patients. We recruited 109 patients admitted with acute paraquat poisoning. They were genotyped for C1236T, G2677T/A, and C3435T single-nucleotide polymorphisms (SNPs) of MDR1 gene...

OBJECTIVE: To investigate the value of serum presepsin concentration measurement in the clinical diagnosis and treatment of patients with pesticide poisoning patients. METHODS: A total of 160 patients with pesticide poisoning were enrolled as study subjects and divided into moderate organophosphate pesticide poisoning group (40 patients) , severe organophosphate pesticide poisoning group (40 patients) , abamectin pesticide poisoning group (40 patients) , and paraquat poisoning group (40 patients)...

This article unveils the development of a paper-based analytical device designed to rapidly detect and clinically diagnose paraquat (PQ) poisoning. Using wax printing technology, we fabricated a PQ detection device by pattering hydrophobic boundaries on paper. This PQ detection device employs a colorimetric sodium dithionite assay or an ascorbic acid assay to indicate the PQ level in a buffer system or in a human serum system in 10 min. In this test, colorimetric changes, blue in color, were observable with the naked eye...

To improve the efficiency of plasma perfusion on eliminating plasma paraquat (PQ), we designed continuous plasma perfusion of dual cartridges in series (CPPDCS) on Diapact Braun CRRT machine. The goals of this study were to evaluate the effective of CPPDCS on paraquat removal in patients with acute paraquat intoxication. Our results show that the PQ clearance rate of dual cartridges was significantly higher than that of single cartridge at 1st, 2nd, 3(rd), and 4th plasma perfusion. Compared with single-cartridge plasma perfusion, CPPDCS significantly reduced the frequency of cartridge replacement, shorten the time of perfusion...

Anecdotal reports have suggested that hypokalemia is an independent predictor of mortality in patients with acute paraquat poisoning. However, the clinical significance of hypokalemia has not been systematically investigated in the early stage of paraquat poisoning. This study aimed to evaluate whether initial hypokalemia is a good predictor of mortality in patients with acute paraquat poisoning within 4 h. We retrospectively analyzed patients who were admitted to the emergency department after paraquat poisoning between September 2012 and January 2015...

The early identification of toxic paraquat (PQ) poisoning in patients critical to ensure timely and accurate prognosis. Though plasma PQ concentration has been reported as a clinical indicator of PQ poisoning, it is not commonly applied in practice due to the inconvenient necessary instruments and operation. In this study, we explored the use of blood routine indexes to identify the degree of PQ toxicity and/or diagnose PQ poisoning in patients via machine learning approach. Specifically, we developed a method based on support vector machine combined with the feature selection technique to accurately predict PQ poisoning risk status, then tested the method on 79 (42 male and 37 female; 41 living and 38 deceased) patients...

OBJECTIVE: This study was conducted to assess the ability of the sequential organ failure assessment (SOFA) and acute physiology and chronic health evaluation (APACHE) II scoring systems, as well as the simplified acute physiology score (SAPS) II method to predict group mortality in intensive care unit (ICU) patients who were poisoned with paraquat. This will assist physicians with risk stratification. MATERIAL AND METHODS: The medical records of 244 paraquat-poisoned patients admitted to the ICU from January 2010 to April 2015 were examined retrospectively...

BACKGROUND: Paraquat (PQ) concentration-time data have been used to predict prognosis for 3 decades. The aim of this study was to find a more accurate method to predict the probability of survival. METHODS: This study included 788 patients with PQ poisoning who were diagnosed using plasma PQ concentration between January 2005 and August 2012. We divided these patients into 2 groups (survivors vs. nonsurvivors), compared their clinical characteristics, and analyzed the predictors of survival...

A simple, sensitive and specific ultra performance liquid chromatography coupled to electrospray tandem high resolution mass spectrometry (UPLC-ESI-HRMS/MS) method has been developed and validated for quantification of paraquat in plasma and urine. The sample preparation was carried out by one-step protein precipitation with acetonitrile. The paraquat was separated with a HILIC column in 10min. Detection was performed using Q Exactive Orbitrap mass spectrometer by Targeted-MS/MS scan mode. Methodological parameters, such as ammonium formate concentration, formic acid concentration, spray voltage, capillary temperature, heater temperature and normalized collision energy were optimized to achieve the highest sensitivity...

The aim of this study was to examine epidemiologic data regarding acute herbicide or insecticide poisoning in adults from 2011 to 2014 at the national level in South Korea. Further, the association between governmental regulations involving pesticides and changes in pesticide poisoning occurrences over time was determined. Data were obtained from the emergency department (ED)-based Injury In-depth Surveillance system conducted by the Korea Center for Disease Control and Prevention (KCDC). Governmental regulations on pesticides were downloaded from the homepage of the Korea Rural Development Administration...

Previous studies have demonstrated that excessive reactive oxygen/nitrogen species (ROS/RNS)‑induced apoptosis is an important feature of the injury to the lung epithelium in paraquat (PQ) poisoning. However the precise mechanisms of PQ‑induced dysfunction of the mitochondria, where ROS/RNS are predominantly produced, remain to be fully elucidated. Whether globular adiponectin (gAd), a potent molecule protective to mitochondria, regulates the mitochondrial function of alveolar type II cells to reduce PQ‑induced ROS/RNS production remains to be investigated...
