[PMID: 38173544 PMCID: PMC10758595 DOI: 10.1093/toxres/tfad124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 10/20/2023] [Accepted: 12/06/2023] [Indexed: 01/05/2024] Open
Abstract
Background Severe refractory hypotension and cardiogenic shock are the main contributors to death in acute aluminum phosphide (ALP) poisoning. Shock index (SI) and modified shock index (MSI) are easily obtained parameters that reflect shock at an early stage. Aim This study aimed to evaluate the role of SI and MSI in the prediction of the severity and outcomes of acute ALP poisoned patients. Patients and methods This cross sectional study was conducted on patients admitted to Tanta University Poison Control Centre with acute ALP poisoning from April 2022 to March 2023. Socio-demographics and toxicological data were taken, findings of clinical examination and laboratory investigations were recoded, SI was calculated by dividing heart rate over systolic blood pressure, and MSI was obtained by dividing heart rate over mean arterial pressure. Poisoning severity was assessed using poisoning severity score (PSS). Patients were divided into groups according to intensive care unit (ICU) admission and mortality. Results The study enrolled 94 patients. The median values of SI and MSI were significantly higher in ICU-admitted patients and non-survivors rather than their comparable groups. Significant positive correlations were observed between each of SI and MSI and PSS. At cut-off >1.14, SI conveyed fair performance to predict ICU admission and mortality (AUC = 0.710 and 0.739, respectively). Similarly, MSI had fair performance to predict ICU admission (AUC = 0.731) and mortality (AUC = 0.744) at cut-off >1.47 and >1.5, respectively. Conclusion Both SI and MSI could be considered simple bedside adjuncts to predict ICU admission and mortality in acute ALP poisoning.

Abstract
Background Aluminum phosphide is a highly toxic pesticide that results in high mortality. To date, there is neither a definitive antidote nor a unified protocol for managing acute aluminum phosphide poisoning. Objectives This cross-sectional questionnaire-based study aims to explore different management approaches and rely on the expertise of Egyptian medical professionals to enhance the prognosis for acute aluminum phosphide poisoning. Subjects and methods A self-administered questionnaire was formulated and electronically distributed according to published literature and experience of senior physicians. Results and conclusions Responses were received from 151 physicians from 10 governorates. Management modalities were variable among respondents. Noradrenaline was used by 90.7% of respondents with no fixed-dose regimen. In all, 84.1% of participants utilized oil in gastrointestinal decontamination; paraffin oil was the most used solution. Overall, 92.1, 61.6, 46.4, and 34.4% of participants used sodium bicarbonate, proton pump inhibitors, IV magnesium sulfate, and antioxidants, respectively. Regarding the frequency of acute aluminum phosphide poisoning, 47% of participants managed these cases daily or a few times a week. Participants' responses denoted a poor prognosis of acute aluminum phosphide poisoning, and high percentages attributed the prognosis to exposure factors rather than treatment modalities. Statistical analysis revealed that using oil in gastrointestinal decontamination improved the outcome by 4.62-fold. Clinical toxicologists were more likely to rescue ≥ 30% of the cases about 3-fold (2.97) than other specialties. Clinical toxicologists used oil in gastrointestinal decontamination, magnesium sulfate, and antioxidant therapy and calculated base deficit before administration of sodium bicarbonate by 7.70-, 5.30-, 3.26-, and 2.08-fold than other specialties.

Abstract
This systematic review and meta-analysis pool evidence available from clinical trials to verify the effect of antioxidants on the outcome of acute aluminum phosphide (AlP) poisoning. A systematic review complied with "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" (PRISMA) Protocols. Meta-analysis was conducted on 10 studies that fulfill eligibility criteria. Four antioxidants were implemented: N-Acetyl cysteine (NAC), L-Carnitine, Vitamin E, and Co-enzyme Q10 (Co Q10). Risk of bias, publication bias, and heterogeneity were assessed to ensure the results' reliability. Antioxidants significantly decrease mortality of acute AlP poisoning around three folds (OR = 2.684, 95% CI: 1.764-4.083; P < .001) and decrease the need for intubation and mechanical ventilation by two folds (OR = 2.391, 95% CI 1.480-3.863; P < .001) compared with control. Subgroup analysis revealed that NAC significantly decreases mortality by nearly three folds (OR = 2.752, 95% CI: 1.580-4.792; P < .001), and vitamin E significantly decreases mortality by nearly six folds (OR = 5.667, 95% CI: 1.178-27.254; P = .03) compared with control. L-Carnitine showed a borderline significance (P = .050). Co Q10 decreased the mortality compared with the control; however, the difference was not statistically significant (P = .263). This meta-analysis provides solid evidence regarding the efficacy of antioxidants in improving the outcome of acute AlP poisoning with reference to NAC. Wide confidence interval and small relative weight affect reliability regarding vitamin E efficacy. Future clinical trials and meta-analyses are recommended. To our knowledge, no previous meta-analysis was conducted to investigate the efficacy of treatment modalities for acute AlP poisoning.

Cardioprotective role of the coenzyme Q10 and coconut oil in acute aluminum phosphide poisoning: a randomized controlled clinical trial. Toxicol Res (Camb) 2023; 12:507-519. [PMID: 37397927 PMCID: PMC10311162 DOI: 10.1093/toxres/tfad037] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 04/13/2023] [Accepted: 05/08/2023] [Indexed: 07/04/2023] Open
Abstract
Aluminum phosphide (ALP)-induced cardiotoxicity is a major cause of high mortality rates. As there is no specific antidote, restoring cardiac hemodynamics is the cornerstone for saving patients. Based on oxidative stress theory in acute ALP poisoning, we examined the cardioprotective role of coconut oil and Coenzyme Q10 (COQ10) in ALP poisoning, focusing on their antioxidant capacity. This study was a randomized, controlled, single-blind, phase II clinical trial conducted at Tanta Poison Control Center over 1 year. Eighty-four ALP poisoned patients received supportive treatment and were randomly allocated to three equal groups. Gastric lavage was performed using sodium bicarbonate 8.4% with saline in group I. Alternatively, group II received 50 ml coconut oil, and group III initially received 600 mg CoQ10 dissolved in 50 ml coconut oil; and repeated 12 hours later. In addition to patient characteristics, clinical, laboratory, electrocardiography (ECG), and total antioxidant capacity (TAC) data were recorded and repeated 12 hours later. Patient outcomes were evaluated. There was no significant difference among groups considering patient characteristics, initial cardiotoxicity severity, vital, laboratory data, ECG changes, and TAC. However, 12 hours post-admissions, group III was significantly improved in all clinical, laboratory, and ECG parameters than comparable groups. Significant correlations were observed between elevated TAC in groups II and III with hemodynamic, serum troponin, and ECG variables. Accordingly, the need for intubation, mechanical ventilation, and the total vasopressor dose was significantly decreased in group III compared with other groups. Therefore, coconut oil and COQ10 are promising cardioprotective adjuvant therapy ameliorating the ALP-induced cardiotoxicity.

Abstract
The use of metal phosphides, particularly aluminum phosphide, poses a significant threat to human safety and results in high mortality rates. This study aimed to determine mortality patterns and predictive factors for acute zinc and aluminum phosphide poisoning cases that were admitted to Menoufia University Poison and Dependence Control Center from 2017 to 2021. Statistical analysis revealed that poisoning was more common among females (59.7%), aged between 10 and 20 years, and from rural regions. Most cases were students, and most poisonings were the result of suicidal intentions (78.6%). A new hybrid model named Bayesian Optimization-Relevance Vector Machine (BO-RVM) was proposed to forecast fatal poisoning. The model achieved an overall accuracy of 97%, with high positive predictive value (PPV) and negative predictive value (NPV) values of 100% and 96%, respectively. The sensitivity was 89.3%, while the specificity was 100%. The F1 score was 94.3%, indicating a good balance between precision and recall. These results suggest that the model performs well in identifying both positive and negative cases. Additionally, the BO-RVM model has a fast and accurate processing time of 379.9595 s, making it a promising tool for various applications. The study underscores the need for public health policies to restrict the availability and use of phosphides in Egypt and adopt effective treatment methods for phosphide-poisoned patients. Clinical suspicion, positive silver nitrate test for phosphine, and analysis of cholinesterase levels are useful in diagnosing metal phosphide poisoning, which can cause various symptoms.

Abstract
Objective This study aimed to assess the severity of poisoning, various scoring systems, including Sequential Organ Failure Assessment (SOFA) score, acute physiology and chronic health evaluation II (APACHE II), Simplified Acute Physiology Score (SAPS II), Modified APACHE II, and poisoning severity score (PSS) were used. In this study, we compared the predictive value of these scoring systems on the outcome of pesticide-poisoned patients. Methods This is a cross-sectional study of pesticide-poisoned patients (140 patients) who were admitted to the intensive care unit (ICU) of Khorshid Hospital, Isfahan, Iran, between January 2015 and 2019. The area under the receiver operating characteristic (AUC) curve and the predictive value of scoring systems were compared. Findings Poisoning was higher in the male population (72.8%). The causes of poisoning were paraquat, (38.6%), aluminum phosphide, (32.1%), and organophosphate, (29.3%). The mean age of the patients was 33.9 years. Most patients (79.3%) attempted suicide. The mortality rate was 46.43%. The mean of "SOFA score," "APACHE II," "SAPS II," "Modified APACHE II," and "PSS" was 5.9; 15.7; 30.02; 15.8; and 1.9, respectively. There was a significant difference in the mean of all scoring systems for outcome prediction. Among all scoring systems, the SAPS II score with the cutoff point (16.5) had the best criteria for outcome prediction (AUC (0.831 ± 0.037), sensitivity (83.1%, 95% confidence interval [CI]: [71.7-91.2]), specificity (75.7%, 95% CI: [64.3-84.9]), positive predictive values (75.0%, 95% CI: [66.4-82.0]), negative predictive values (83.6%, 95% CI: [74.5-89.9]). Conclusion The SAPS II scoring system may be a suitable indicator for outcome predictions in pesticide-poisoned patients in the ICU.

Abstract
Aluminum phosphide (AlP) poisoning is a serious medical emergency with a high mortality rate. The absence of an exact antidote for AlP poisoning necessitates the quest for alternative treatment options. The study sought to assess the efficacy of adding L-carnitine or medicated paraffin oil to the conventional approach of treatment employed in cases of acute AlP poisoning. We conducted a 1 year, randomized, controlled, parallel-group, single-blind clinical study. 96 individuals with acute AlP poisoning were randomly assigned to one of three groups. The standard AlP therapy was administered to all groups according to the Poison Control Center guidelines at the Ain-Shams University hospitals. All patients underwent a medical history review, clinical examination, and laboratory tests. The outcomes were assessed. The participants in the study groups had mean ages ranging from 25.6 to 26.3 years. The cases analyzed were evenly distributed between genders, with the majority originating from rural areas. The average delay time varied from 2.9 to 4.2 h. All patients in the study reported ingesting AlP during suicide attempts. 12 hours after admission, many clinical and biochemical data improved in both intervention groups including cytochrome c oxidase, caspase-3, caspase-9, catalase, and superoxide dismutase. The intervention groups required significantly less mechanical ventilation and had a lower mortality rate than the control group. Decontamination with paraffin oil could be advantageous for reducing the severity of AlP poisoning, improving prognosis, and lowering the mortality rate.

Abstract
The decision of intensive care unit (ICU) admission in acute pesticide poisoning is often challenging, especially in developing countries with limited resources. This study was conducted to compare the efficacy of the Acute Physiology and Chronic Health Evaluation II (APACHE II), Modified Early Warning Score (MEWS), and Poisoning Severity Score (PSS) in predicting ICU admission and mortality of acute pesticide-poisoned patients. This prospective cohort study included all patients admitted to Tanta University Poison Control Center with acute pesticide poisoning from the start of March 2018 to the end of March 2019. Patient data, including demographic and toxicological data, clinical examination, laboratory investigation, and score values, were collected on admission. Out of 337 acute pesticide-poisoned patients, 30.5% were admitted to the ICU, including those poisoned with aluminum phosphide (ALP) (81.5%) and organophosphates (OP) (18.5%). Most non-survivors (86.6%) were ALP poisoning. The PSS had the best discriminatory power in predicting ICU admission and mortality, followed by APACHE II and MEWS. However, no significant difference in predicting ICU admission of OP-poisoned patients was detected between the scores. Additionally, no significant difference in mortality prediction of ALP-poisoned patients was found between the PSS and APACHE II. The PSS, APACHE II, and MEWS are good discriminators for outcome prediction of acute pesticide poisoning on admission. Although the PSS showed the best performance, MEWS was simpler, more feasible, and practicable in predicting ICU admission of OP-poisoned patients. Moreover, the APACHE II has better sensitivity for mortality prediction of ALP-poisoned patients.

Abstract
INTRODUCTION Cardiotoxicity represents the primary cause of death in acute aluminum phosphide (AlP) poisoning. Prompt supportive care can improve patient survival. This study assessed the role of echocardiography in estimating the survival probability of AlP-poisoned patients admitted to the intensive care unit. METHODS A prospective cohort study of symptomatic acute AlP poisoned patients was conducted between September 2019 and December 2020. Patients were subjected to history taking, clinical examination, To be included, patient evaluation needed to include electrocardiographic (ECG) and echocardiographic studies. The statistical analysis assessed the association between patient survival and relevant factors. Survival analysis was performed using the Kaplan-Meier survival curve and Cox proportional hazard regression. RESULTS A total of 90 patients met inclusion criteria. Electrocardiographic abnormalities were detected in 38.1% of survivors and 82.6% of non-survivors (p < 0.001). Survivors had a higher mean left ventricle ejection fraction (LVEF) (50.86 ± 6.30% vs. 26.52 ± 7.64%, respectively, p < 0.001) and a lower percentage of global LV hypokinesia (4.8% vs. 94.2%, p < 0.001). The mean survival time was higher among patients with LVEF ≥ 50% than those with LVEF = 41-49% and ≤ 40% (p = 0.014 and 0.001, respectively). The hazard of death was 4.42 and 5.40 times greater in patients with LVEF ≤ 40% or with global LV hypokinesia, respectively. Regression revealed that the global LV hypokinesia, ECG abnormalities, and decreased LVEF and oxygen saturation were significantly associated with the risk of death (hazard ratios: 4.382, 3.348, 0.957, and 0.971, respectively). CONCLUSIONS Echocardiography represents a valuable diagnostic tool to assess cardiac function in acute AlP poisoning. Both LVEF and global LV hypokinesia significantly impact the survival of AlP-poisoned patients. Echocardiography was superior to ECG changes in terms of accuracy for the prediction of mortality.

Abstract
Introduction We recently derived a simplified 3-point PGI score (representing blood pH < 7.25, Glasgow coma scale [GCS] score < 13, and impaired systolic blood pressure [SBP] < 90 mm Hg), which accurately predicted in-hospital case fatality ratio (CFR) in acute aluminum phosphide poisoning. The present study aimed to validate the PGI score and compare it with Acute Physiologic Assessment and Chronic Health Evaluation (APACHE) II score, Sequential Organ Failure Assessment score (SOFA), and Simplified Acute Physiology Score (SAPS) II scores. Patients and Methods We performed a prospective cohort study in adult patients with aluminum phosphide ingestion admitted in PGIMER, Chandigarh (India), from April 2013 to August 2014. A univariant analysis detected the association of various baseline variables with CFR. Correlation of the PGI score with SOFA, SAPS-II, and APACHE-II scores was performed using Spearman's correlation (rs , range -1 to +1) and scatter plots. Results Seventy-six patients were enrolled (mean age, 28.3 years; 41 males). CFR was 60.5%. PGI score variables-pH, GCS, and impaired SBP predicted CFR (P-value <0.001). Among patients with a total PGI score of 3 or 2, 100% died, compared with 50% in score 1 and 10.7% in score 0. Baseline PGI, SOFA, SAPS-II, and APACHE-II scores predicted CFR (P-value <0.001). There was a positive correlation between the PGI score and SOFA score (rs , 0.855), SAPS-II score (rs , 0.861), and APACHE-II score (rs , 0.883). The P-value for all rs values was <0.001. Conclusion The PGI score is a validated toxidrome-specific and simplified risk-stratification tool. Validation in other populations is warranted to confirm its routine use.

Abstract
Introduction: According to statistics provided by the forensic medicine facility of Iran, there are a high number of Aluminum phosphide (ALP) poisoning-related deaths in the country; while the mortality rate varies in different studies. This study aimed to determine a pooled estimate of ALP poisoning mortality rate in Iran. Methods: The present study was a systematic review and meta-analysis of the mortality rate of ALP poisoning in Iran. Through the quarry of Persian and English databases, using “aluminum phosphide”, “phosphine”, “rice pills”, “poisoning”, and “Iran” as keywords, and no time restrictions, studies reporting mortality rate in ALP poisoning cases were collected. The random-effects model was used to pool the proportions of mortality and age of survivors versus non-survivors. Results: 21 studies with 3432 cases of ALP poisoning were included in this meta-analysis. The pooled mortality rate of ALP poisoning in Iran was 39.6%, (95% CI: 31.5%-47.9%; I2 = 95%). Since there was significant publication bias, the trim-and-fill correction was conducted and the corrected pooled mortality rate was estimated to be 27.3% (95% CI: 18.9%- 36.5%), which is the rate that should be considered for clinical guidance. Morality rate in male and female patients was 62.3% (95% CI: 53.5%-70.8%) and 37.7% (95% CI: 29.2%-46.5%), respectively (p < 0.01). Survivors had significantly lower mean age than non-survivors (SMD: -0.26 (95% CI: -0.37 to -0.15); p < 0.01; I2=0%). Conclusion: According to this report, the Mortality rate of ALP poisoning in Iranian population is about 27%, with men having a higher fatality rate than women. Poisoning at a younger age is associated with better results.

Abstract
Methanol intoxication is a global problem with serious morbidities and mortalities. Apart from the lifelong disabilities experienced by methanol intoxication survivors, mortality rates of up to 44% of exposed patients have been reported. The aim of the current study was to outline the early findings that could be utilized as effective in-hospital outcome predictors among cases of methanol exposure. Furthermore, the role of the Sequential Organ Failure Assessment (SOFA) score was evaluated as an early in-hospital outcome indicator among patients presented with acute methanol intoxication. A multicenter study including 37 patients diagnosed with acute methanol intoxication and referred to three major poison control centers in Saudi Arabia during the past 3 years (January 1, 2018-January 1, 2021) was conducted. Data including demographics, exposure history, presenting complaints, clinical findings, and laboratory investigation were collected. The patients were scored on Glasgow Coma Scale (GCS), Poison Severity Score (PSS), and SOFA score on admission. Out of the presented patients, 83.8% were alcoholic men. No deaths have been reported, and 51.4% were discharged with unfavorable outcomes, including 29.7% suffered optic neuropathy and blindness, 18.9% showed acute renal impairment, and 10.8% were complicated with respiratory failure. The diastolic blood pressure, anion gap, visual acuity, number of hemodialysis sessions, PSS, duration of Intensive Care Unit (ICU) stay, and SOFA score were all significant organ failure predictors (P < 0.05). However, only the SOFA score showed the best significant prediction on multivariate analysis, with an odds ratio (95% confidence interval) of 0.10 (0.04-0.17) and P = 0.003. At a cutoff of greater than 4.5, the SOFA score could significantly predict unfavorable outcomes with area under curve (AUC) = 0.955, accuracy 89.2%, specificity 94.4%, and sensitivity 84.2%. Early identification of methanol exposed patients at risk is critical and lifesaving. The SOFA score is a substantially useful and early inclusive unfavorable outcome predictor.

CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2021; 25:29. [PMID: 33461588 PMCID: PMC7814606 DOI: 10.1186/s13054-020-03408-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Accepted: 11/24/2020] [Indexed: 12/23/2022]
Abstract
Background A prediction model of mortality for patients with acute poisoning has to consider both poisoning-related characteristics and patients’ physiological conditions; moreover, it must be applicable to patients of all ages. This study aimed to develop a scoring system for predicting in-hospital mortality of patients with acute poisoning at the emergency department (ED).
Methods This was a retrospective analysis of the Injury Surveillance Cohort generated by the Korea Center for Disease Control and Prevention (KCDC) during 2011–2018. We developed the new-Poisoning Mortality Scoring system (new-PMS) to generate a prediction model using the derivation group (2011–2017 KCDC cohort). Points were computed for categories of each variable. The sum of these points was the new-PMS. The validation group (2018 KCDC cohort) was subjected to external temporal validation. The performance of new-PMS in predicting mortality was evaluated using area under the receiver operating characteristic curve (AUROC) for both the groups. Results Of 57,326 poisoning cases, 42,568 were selected. Of these, 34,352 (80.7%) and 8216 (19.3%) were enrolled in the derivation and validation groups, respectively. The new-PMS was the sum of the points for each category of 10 predictors. The possible range of the new-PMS was 0–137 points. Hosmer–Lemeshow goodness-of-fit test showed adequate calibration for the new-PMS with p values of 0.093 and 0.768 in the derivation and validation groups, respectively. AUROCs of the new-PMS were 0.941 (95% CI 0.934–0.949, p < 0.001) and 0.946 (95% CI 0.929–0.964, p < 0.001) in the derivation and validation groups, respectively. The sensitivity, specificity, and accuracy of the new-PMS (cutoff value: 49 points) were 86.4%, 87.2%, and 87.2% and 85.9%, 89.5%, and 89.4% in the derivation and validation groups, respectively. Conclusions We developed a new-PMS system based on demographic, poisoning-related variables, and vital signs observed among patients at the ED. The new-PMS showed good performance for predicting in-hospital mortality in both the derivation and validation groups. The probability of death increased according to the increase in the new-PMS. The new-PMS accurately predicted the probability of death for patients with acute poisoning. This could contribute to clinical decision making for patients with acute poisoning at the ED.

Abstract
Zinc phosphide (Zn3P2) is a phosphine-generating pesticide. Serious hepatotoxicity or cardiotoxicity might develop late in initially stable patients. The current prospective study aimed to predict Zn3P2-induced hepatotoxicity and cardiotoxicity. This prospective cross-sectional study included 150 patients admitted to the Alexandria Poison Center (APC) for over 6 months (from August 2018 to January 2019). The recorded patients' data included personal data, poisoning, medical history, clinical assessment using the poisoning severity score (PSS), investigations, and the outcome. The mean age of the patients was 23.36 ± 13.53 years. Females constituted 68.7%, and 76% of the patients ingested Zn3P2 deliberately. Only two cases that ingested the highest amount of Zn3P2 had radio-opaque shadows in the abdominal plain X-ray. The peak of clinical manifestations was in 12 h, whereas the peak liver transaminases (alanine aminotransferase (ALT), aspartate aminotransferase (AST)) and cardiac enzymes (creatine phosphokinase (CPK), creatine kinase-muscle/brain (CK-MB), troponin) were in 24 h. No fatalities were reported, 56.7% are completely cured, 37.3% are discharged on consent, and 6% are discharged with elevated liver and/or cardiac enzymes. The receiver operating characteristic (ROC) curve was applied. Persistent elevation of liver enzymes after 72 h could be predicted if the ingested amount > 3.5 (accuracy 86.2%), time till hospitalization > 5 h (accuracy 85.9%), PSS > 1 with (accuracy 58.9%), AST > 50 U/L (accuracy 86.2%), or ALT > 82 U/L (accuracy 86.3%). Elevation of cardiac enzymes could be predicted if the ingested amount > 2.5 sachets (accuracy 99.5%), time till hospitalization > 5 h (accuracy 99.7%), PSS > 1 with (accuracy 61.2%), CPK > 260 U/L (accuracy 99.9%), CK-MB > 6 ng/mL (accuracy 99.7%), or troponin > 0.9 ng/mL (accuracy 99.8%).

Abstract
Incorporating the toxidrome-specific prognostic systems into the daily emergency department practice might become a standard of care in low- and middle-income countries. The PGI score is appealing because it is quick and easy, it accurately identifies high-risk patients at in-hospital mortality, and it shows promise in predicting those at low risk. Although further validation of the PGI score is required in more extensive studies, it can help direct appropriate resources to those most likely to benefit and stratify patients for testing novel clinical interventions.

Abstract
Aluminum phosphide (AlP) poisoning had high morbidities and mortalities with absence of a standardized approach for the treatment. The present study investigated the efficiency of GIT decontamination methods and Coenzyme Q10(Co Q10) (Ubiquinone) in improving the outcome of acute AlP poisoning. A total of 90 patients were included and all patients received immediately supportive measures, then they distributed into three equal groups: In group I, gastric lavage was done using KMNO4 solution (1:10 000); group II received 250-500 ml liquid paraffin oil orally; group III received 300 mg of Co Q10 dissolved in liquid paraffin. Co Q10 was continued in a dose of 200 mg/day every 12 h. Follow-up blood pressure, arterial blood gases, serum troponin level and need for intubation revealed that the best improvement was in group III followed by group II. The percentage of survivors was 76.67% in group III and 70% of the patients had no residual effects. In group II, the survivors were 63.33%, and 36.67% of the cases discharged without sequelae. The survivors in group I constituted 26.67% and only 16.67% of the patients had no residual effects. GIT decontamination with aqueous solutions in acute AlP poisoning should be avoided. Rapid oral intake of any available oil as a prehospital treatment or immediately on hospital admission could critically improve the outcome of acute AlP poisoning. Besides, the addition of Co Q10 to the oil further improve patients' prognosis. HighlightsAcute aluminum phosphide (AlP) poisoning is associated with high mortalities.The appropriate method of GIT decontamination in acute AlP poisoning is controversy.Conventional gastric lavage was associated with poor prognosis in acute AlP poisoning.GIT decontamination using liquid paraffin oil improved outcome of acute AlP poisoning.Coenzyme Q10 ameliorated AlP toxicity with improvement of cardiac functions.

Abstract
Introduction Aluminum phosphide (AlP) ingestion for self-harm is associated with a high case-fatality rate (CFR) in low- and middle-income countries. A reliable and accurate prognostic scoring tool is required for appropriate triaging, to guide clinical decision-making, and to evaluate the efficacy of therapeutic interventions for the patients with AlP toxicity. Materials and methods We performed a prospective cohort study in a tertiary care hospital in north India in patients aged 15 years and over with acute AlP poisoning, investigating the parameters associated with CFR, and developing a reliable and simple prediction score. Results The CFR was 51% in this cohort of 105 patients. Three parameters—pH <7.25, score on Glasgow coma scale (GCS) <13, and systolic blood pressure (SBP) <87 mm Hg were most robust predictors of CFR (odds ratio; 12.614, 18.621, and 17.600, respectively; area under the receiver operating characteristic curve—0.808, 0.796, and 0.776, respectively). Based on these parameters (with 1 point to each), a prognostic score was developed, ranging from 0 to 3 points. A total score of 3 had a 98.2% specificity and a positive predictive value of 96.4%, whereas a score ≤1 had a 100% sensitivity and 100% negative predictive value. Conclusion A scoring system based on low pH (P), low GCS score (G), and impaired or low SBP (I) (“PGI” score) may provide a simplified predictive model for mortality in AlP poisoning.
