Epidemiologic Trends In Children With Toxicologic Exposures Requiring Intensive Care Before and During the COVID-19 Pandemic.

OBJECTIVE: Pediatric poison exposures are a common reason for pediatric intensive care unit (PICU) -admission. The purpose of this study was to examine the exposure trends and patient outcomes in 2018-2019 compared with 2020-2021 amidst the COVID-19 pandemic. METHODS: This was a retrospective cohort study of patients 18 years of age or younger with a suspected toxicologic exposure from January 2018 to March 2021. The primary endpoint was rate of PICU admissions between the 2 cohorts. Secondary endpoints included medical outcome stratified by severity, PICU length of stay, and need for mechanical ventilation. RESULTS: Our study included a total of 340 patients with median age 14.5 (IQR, 11.9-16.1) years. There was no significant difference in age, sex, or race between the 2 cohorts. The percentage of patients admitted to the PICU for poison exposures was significantly higher in the COVID-19 cohort compared with the pre-COVID-19 cohort (8.4% vs 3.7%, p < 0.01). Severity of medical outcomes differed between the groups; the COVID-19 cohort had more extreme clinical presentations of no effect or death (p < 0.01). No significant difference was found among the remaining secondary outcomes. Classes of substances ingested were comparable with baseline poison center data. CONCLUSIONS: Poisoning-related PICU admissions occurred at more than twice the pre-pandemic rate. This may emphasize the effect of the COVID-19 pandemic on pediatric access and exposure to poisons.

Safety of Physostigmine for Pediatric Antimuscarinic Poisoning.

INTRODUCTION: Physostigmine fell out of widespread use in the 1980s due to safety concerns; however, more recent research has demonstrated that its safety profile is better than previously thought. These studies have mainly included adults. We theorized that improved safety data may lead to more acceptance. Our objectives, therefore, were to characterize current frequency of use of physostigmine in pediatric patients as well as to study adverse effect rates in a national pediatric patient population. METHODS: The National Poison Data System was queried for cases of patients aged 0-18 years that involved single-substance exposures to antimuscarinic xenobiotics that were reported to a poison center between January 1, 2000, and December 31, 2020. Cases were stratified into groups by therapy received: benzodiazepines alone, benzodiazepines and physostigmine, physostigmine alone, or no physostigmine or benzodiazepines. Patient demographics, clinical effects, and medical outcomes were analyzed. RESULTS: A total of 694,132 cases were reviewed, and 150,075 were included for analysis. Nearly 5% (7562/150,075) of patients received specific pharmacological therapy with benzodiazepines, physostigmine, or both. A benzodiazepine as a single agent was the most frequently used pharmacologic therapy (92% of 7562). Among patients receiving any pharmacological therapy, only 8.3% (n = 627) of patients received physostigmine. Frequency of serious outcomes significantly increased across the study period among patients receiving benzodiazepines alone or with physostigmine. There was no increase in serious outcomes among patients receiving only physostigmine. CONCLUSIONS: Physostigmine frequency of use was low overall, but when used, was associated with less severe outcomes when compared to benzodiazepines.

"Ghost tablet" husks excreted in feces in large bupropion XL overdose.

BACKGROUND: Extended-release medications are widely prescribed across the spectrum of medical specialties; however, there is heterogeneity in how they are formulated. Commonly, they consist of an insoluble matrix or shell from which drug elutes, which may then be observed by patients when excreted in feces. We describe the case of a patient who ingested a large amount of extended-release bupropion tablets and subsequently passed a large number of these so-called "ghost tablets" in his stool. CASE DETAILS: A 19-year-old male presented in status epilepticus following intentional overdose of an unknown substance. He had prolonged QRS and QT intervals on ECG, hypotension requiring vasopressors, and tachycardia, and progressed to cardiac arrest and respiratory failure. On hospital day 4, he passed several large bowel movements containing apparent tablets. Serum bupropion and hydroxybupropion levels performed on serum taken at time of admission were 1800 ng/mL and 4200 ng/mL, respectively. Case Discussion: "Ghost tablets," the insoluble remnant of some extended-release dosage forms, have been previously reported to appear in patients' stool in the course of therapeutic dosing. We present the case of a considerable quantity of these ghost tablets recovered from stool following a large bupropion XL overdose. CONCLUSION: Healthcare providers should be aware of the potential for this phenomenon to occur in poisoned patients. It should be documented as physical evidence of overdose in addition to clinical evidence.

Toxicity of Bupropion Overdose Compared With Selective Serotonin Reuptake Inhibitors.

OBJECTIVES: Adolescent depression and attempted and completed suicide are increasing in the United States. Because suicide is often impulsive, the means of self-harm are frequently items of convenience like medication. Authors of a recent study compared tricyclic antidepressant overdose to bupropion overdose. Fluoxetine and escitalopram are the only agents with Food and Drug Administration approval for pediatric depression, but off-label bupropion prescriptions are common. We sought to compare the effects of selective serotonin reuptake inhibitors (SSRIs) and bupropion in overdose. METHODS: This was an analysis of the National Poison Data System from June 2013 through December 2017 for adolescent (ages 10-19) exposures to SSRIs or bupropion coded as "suspected suicide." Demographics, clinical effects, therapies, and medical outcome were analyzed. RESULTS: There were 30 026 cases during the study period. Sertraline and fluoxetine accounted for nearly 60%, whereas bupropion was reported in 11.7%. Bupropion exposure was significantly associated with death (0.23% vs 0%; P < .001) or serious outcome (58.1% vs 19%; P < .001) as well as the 10 most common clinical effects, including seizures (27.0% vs 8.5%; P < .001) and hallucinations (28.6% vs 4.3%; P < .001). Bupropion exposure was significantly associated with the need for cardiopulmonary resuscitation (0.51% vs 0.01%; P < .001), intubation (4.9% vs 0.3%; P < .001), vasopressors (1.1% vs 0.2%; P < .001), and benzodiazepines (34.2% vs 5.5%; P < .001). There was a significant increase in all exposures and in proportion of serious outcomes over time. CONCLUSIONS: Adolescents who attempt self-harm are at higher risk for serious morbidity and poor outcomes with bupropion than with SSRIs. These risks, and the patient's propensity for self-harm, should be evaluated when therapy with bupropion is considered.
