Expert Opin Drug Metab Toxicol 2023; 19:297-317. [PMID: 37436926 DOI: 10.1080/17425255.2023.2223959] [Citation(s) in RCA: 12] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Accepted: 06/05/2023] [Indexed: 07/14/2023]
Abstract
INTRODUCTION Paracetamol is one of the most used medicines worldwide and is the most common important poisoning in high-income countries. In overdose, paracetamol causes dose-dependent hepatotoxicity. Acetylcysteine is an effective antidote, however despite its use hepatotoxicity and many deaths still occur. AREAS COVERED This review summarizes paracetamol overdose and toxicity (including mechanisms, risk factors, risk assessment, and treatment). In addition, we summarize the epidemiology of paracetamol overdose worldwide. A literature search on PubMed for poisoning epidemiology and mortality from 1 January 2017 to 26 October 2022 was performed to estimate rates of paracetamol overdose, liver injury, and deaths worldwide. EXPERT OPINION Paracetamol is widely available and yet is substantially more toxic than other analgesics available without prescription. Where data were available, we estimate that paracetamol is involved in 6% of poisonings, 56% of severe acute liver injury and acute liver failure, and 7% of drug-induced liver injury. These estimates are limited by lack of available data from many countries, particularly in Asia, South America, and Africa. Harm reduction from paracetamol is possible through better identification of high-risk overdoses, and better treatment regimens. Large overdoses and those involving modified-release paracetamol are high-risk and can be targeted through legislative change.

Abstract
Objectif : Estimer l’évolution du nombre de passages aux urgences pour intoxications aiguës (IA) lors des périodes de confinement en 2020 par rapport à l’année précédente.
Matériels et méthode : Une étude rétrospective multicentrique de type transversale a été menée en utilisant les données des résumés de passages aux urgences. Deux périodes ont été étudiées en 2020 : période 1 = 1er confinement et période 2 = 2e confinement et ont été comparées aux mêmes périodes en 2019. Les diagnostics pour IA volontaires ou accidentelles toutes causes ont été définis à partir du code CIM-10. Le critère de jugement principal a été la variation du nombre de passages aux urgences pour IA entre les périodes de confinement en 2020 et les périodes de référence en 2019.
Résultats : Comparé à la même période en 2019, le nombre de passages aux urgences pour IA a baissé de 31 % (p = 0,001) pendant le premier confinement et de 18 % (p = 0,07) pendant le deuxième confinement. Le nombre de passages pour IA médicamenteuse a baissé de 3 % (p = 0,035) pendant le deuxième confinement en comparaison à 2019. Les caractéristiques des patients consultant pour IA étaient comparables dans chacune des périodes.
Conclusion : Dans cette étude, une diminution du nombre de passages aux urgences pour IA a été observée pendant les périodes de confinement en 2020 par rapport aux mêmes périodes l’année précédente.

Abstract
Knowledge about current trends and epidemiology in poisonings is important to maintain quality in diagnostics, treatment and prevention. We performed a cross-sectional study of all cases (n = 261) admitted with drug poisoning to Aalborg University Hospital during 1 year in 2017-2018. Median age was 30 (22-49) years, and 58% were female. Fifty percent were suicide attempts. In most cases, involved drugs were identified by history taking; blood analysis barely revealed any additional paracetamol and salicylicate poisonings. Drugs prescribed to the patient or available over the counter were involved in nearly two thirds of cases. Weak analgesics dominated by paracetamol (n = 91, 35%) was the most frequently involved group of drugs followed by opioids and benzodiazepines. Gender differences were observed with respect to involvement of weak analgesics and central stimulants. A higher prevalence of unidentified involved drugs was observed in 26 cases (10%) in which the length of admission exceeded 2 days and/or intensive care was needed. No deaths, cardiac arrhythmias or physical complications occurred. Thus, current handling of the acute poisoning seems effective in most cases. However, a more tailored use of blood analyses including a toxicological screen in selected cases may represent an opportunity for improvement.

Self-poisoning as a cause of admission in a medical intensive care unit and a question of misuse of prescription medications. Heart Lung 2021; 51:17-21. [PMID: 34731692 DOI: 10.1016/j.hrtlng.2021.09.006] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Revised: 09/08/2021] [Accepted: 09/08/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND Self-poisoning accounts for between 3 and 17% of intensive care unit (ICU) admissions. OBJECTIVES To display the misused substances, intention, and outcome of patients admitted to the ICU due to self-poisoning. METHODS A retrospective review of ICU admissions using an electronic patient database was performed. RESULTS A total of 149 patients were admitted, accounting for 4.6% of ICU admissions. Self-poisoning with self-harm was more frequent than without self-harm intent (62.4% vs. 37.6%). 64.4% of ingested substances were misused prescribed drugs. Females used antipsychotics (X2 = 15, p< 0.05) and benzodiazepines (X2 =11.52, p< 0.05), and males ingested antipsychotics (X2 = 12, p< 0.05) with a self-harm intent. Antipsychotics were always used with a self-harm intent. Illicit drugs (X2 =9.14, p< 0.05) and ethanol (X2 =7.34, p< 0.05) were mostly used without self-harm intent. 102 patients (68.5%) continued treatment in a psychiatric clinic, more often women (X2 (1,N = 145)=7.94, p< 0.005). The readmission rate was low. Mortality was 2.6%. CONCLUSION Self-poisoning is an infrequent cause of ICU admission. Prescribed psychotropic medications, including benzodiazepines, antipsychotics, and antidepressants were the most frequently misused substances. Psychiatric consultation before the ICU discharge and subsequent psychiatric treatment might lower the repetition and readmission rate.

An analysis of 1344 consecutive acute intoxication cases admitted to an academic emergency medicine department in Turkey. North Clin Istanb 2021; 8:377-384. [PMID: 34585073 PMCID: PMC8430352 DOI: 10.14744/nci.2020.98957] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Accepted: 12/25/2020] [Indexed: 12/05/2022] Open
Abstract
OBJECTIVE: One of the major causes of emergency department (ED) visits is acute poisoning. Acute intoxications occur soon after either single or multiple exposures to toxic substances, and they started to be a more serious problem in developing countries. The objective of this study was to investigate the local patterns of acute intoxications, as well as clinical and sociodemographic characteristics of patients with acute poisoning, admitted to our hospital’s ED. METHODS: This single-center, retrospective study was conducted using medical records of consecutive patients admitted to the ED between January 2016 and December 2017. RESULTS: A total of 1344 patients were included in the statistical analysis. Of these, 673 (50.1%) were female. Mean (±SD) age was 32.2 (±12.0), ranging between 17 and 84 years. The highest number of poisoning cases was observed in summer, especially in July (10.0%) and August (11.8%), whereas lowest number of admissions related to poisoning occurred during winter in November (5.1%) and December (5.2%). Among admitted cases, many were suicide attempts (55.7%) followed by non-intentional (accidental) ingestion of non-pharmaceutical (n=553, 41.2%) and pharmaceutical agents (n=42, 3.1%). Single agents were the most common cause of acute intoxications (63.2%) rather than multidrug intoxications. Most frequently observed causes of poisonings were recreational substances (30.0%) and agents exposed by inhalation (13.2%). INR, lactate, and pH levels at admission were significant predictors of 7-day mortality without a significant paired difference between each other. The AUCs for each were 0.89 (SE 0.04; p<0.0001), 0.84 (SE 0.10; p=0.0007), and 0.79 (SE 0.11; p=0.0102), respectively. CONCLUSION: We conclude that recreational substances and medicinal drug intoxications were the leading cause of acute poisonings in our region, occurring mostly during the summer.
