The COVID-19 outbreak affected mental health globally. One of the major concerns following the COVID-19 pandemic was increased incidence of risky behaviors including alcohol consumption. This study evaluates the trend of alcohol poisoning in Loghman-Hakim Hospital (LHH), the main referral center of poisoning in Tehran, during the 2-year period from 1 year prior to 1 year after the onset (February 23rd, 2020) of the COVID-19 epidemic in Iran. All patients admitted with alcohol intoxication from February 23rd, 2019 to February 22nd, 2021 were evaluated and patient data extracted from LHH electronic hospital records. Alcohols were categorized as toxic (methyl alcohol) and non-toxic (ethyl alcohol). Of 2483 patients admitted, 796/14,493 (5.49%) and 1687/13,883 (12.15%) had been hospitalized before and after the onset of the COVID-19 epidemic in Iran, respectively. In total, 140 patients did not survive, of whom 131 (93.6%) were confirmed to have methanol intoxication. Mortality was significantly higher during the outbreak (127 vs 13; P < 0.001; OR: 4.90; CI 95%: 2.75 to 8.73). Among the patients, 503 were younger than age 20. Trend of alcohol intoxication showed increases in children (57 vs 17) and adolescents (246 vs 183) when compared before and after the COVID-19 epidemic outbreak. A total of 955 patients were diagnosed with methanol toxicity which occurred more frequently during the COVID-19 era (877 vs 78; P < 0.001; OR: 10.00; CI 95%: 7.75 to12.82). Interrupted time series analysis (April 2016-February 2021) showed that in the first month of the COVID-19 epidemic (March 2020), there was a significant increase in the alcohol intoxication rate by 13.76% (P < 0.02, CI = [2.42-24.91]). The trend of alcohol intoxication as well as resulting mortality increased in all age groups during the COVID-19 epidemic in Iran, indicating urgent need for the prevention of high-risk alcohol use as well as improved treatment.

A methanol poisoning outbreak occurred in Iran during the initial months of coronavirus disease 2019 (COVID-19) pandemic. We aimed to evaluate the epidemiology of the outbreak in terms of hospitalizations and deaths. A cross-sectional linkage study was conducted based on the hospitalization data collected from thirteen referral toxicology centers throughout Iran as well as mortality data obtained from the Iranian Legal Medicine Organization (LMO). Patient data were extracted for all cases aged > 19 years with toxic alcohol poisoning during the study period from February until June 2020. A total of 795 patients were hospitalized due to methanol poisoning, of whom 84 died. Median [interquartile ratio; IQR] age was 32 [26, 40] years (range 19-91 years). Patients had generally ingested alcohol for recreational motives (653, 82.1%) while 3.1% (n = 25) had consumed alcohol-based hand sanitizers to prevent or cure COVID-19 infection. Age was significantly lower in survivors than in non-survivors (P < 0.001) and in patients without sequelae vs. with sequelae (P = 0.026). Twenty non-survivors presented with a Glasgow Coma Scale (GCS) score > 8, six of whom were completely alert on presentation to the emergency departments. The time from alcohol ingestion to hospital admission was not significantly different between provinces. In East Azerbaijan province, where hemodialysis was started within on average 60 min of admission, the rate of sequelae was 11.4% (compared to 19.6% average of other provinces)-equivalent to a reduction of the odds of sequelae by 2.1 times [95% CI 1.2, 3.7; p = 0.009]. Older patients were more prone to fatal outcome and sequelae, including visual disturbances. Early arrival at the hospital can facilitate timely diagnosis and treatment and may reduce long-term morbidity from methanol poisoning. Our data thus suggest the importance of raising public awareness of the risks and early symptoms of methanol intoxication.

Blood lead concentrations among pediatric patients with abdominal pain: a prospective cross-sectional study.

BMC Gastroenterol 2021 Dec 20;21(1):493. Epub 2021 Dec 20.

Washington Poison Center, University of Colorado Anchutz Medical Campus, Rocky Mountain Poison & Drug Safety, Denver, CO, Seattle, WA, USA.

Background: Lead exposure is one of the most menacing of environmental exposures, particularly in children. Children are more susceptible to the effects of lead which manifest in many organ systems, including interference with mental and motor development. Lead poisoning can cause colicky abdominal pain. In this study, the authors sought to evaluate the prevalence of elevated blood lead level (BLL) and its contributing factors among pediatric patients presenting with abdominal pain. An epidemic of lead poisoning in adults was previously uncovered, and thus a concern for pediatric lead poisoning was raised.

Methods: Pediatric patients presenting to two pediatric clinics in Tehran with abdominal pain were eligible for enrollment in a descriptive prospective cross-sectional study. A predesigned questionnaire was filled for each patient by their consenting parents. The questionnaire queried demographic information, environmental, social, and other relevant parameters for lead exposure. After completion of the questionnaire, biometrics were obtained, and a blood sample was taken from each patient for measurement of BLL and complete blood count.

Results: A total of 187 patients were enrolled in the study. Of them, almost 20% had BLL ≥ 5 µg/dL. Univariate analysis showed that age (p = 0.002, OR 3.194, CI 95% 1.504-6.783), weight (p = 0.009, OR 2.817, CI 95% 1.266-6.269), height (p = 0.003, OR 3.155, CI 95% 1.443-6.899), and playing with both plastic and cotton toys (p = 0.03, OR 2.796, CI 95% 1.072-7.295) were significant predictors of high BLLs. Maternal level of education correlated with blood lead concentrations (p = 0.048, OR 2.524, CI 95% 1.006-6.331).

Conclusions: A clinically significant number of cases of abdominal pain may have high BLLs. Specific attention should be paid to children presenting with abdominal pain, especially due to the detrimental effects of lead on their mental and motor development.

Prevalence of clinical and radiologic features in methanol-poisoned patients with and without COVID-19 infection.

Acute Med Surg 2021 Jan-Dec;8(1):e715. Epub 2021 Dec 6.

Social Determinants of Health Research Center Shahid Beheshti University of Medical Sciences Tehran Iran.

Aim: The aim of the current study was to evaluate the prevalence of coronavirus disease (COVID-19) in methanol-poisoned patients admitted to two toxicology academic centers during the COVID-19 outbreak and determine their clinical features and chest/brain computed tomography (CT) findings.

Methods: Methanol-poisoned patients who had been referred during the COVID-19 pandemic were evaluated for signs and symptoms of COVID-19 by chest CT scans and/or polymerase chain reaction test.

Results: A total of 62 patients with confirmed methanol poisoning were enrolled in the study, with a median (interquartile range) age of 35 (28-44) years. Thirty-nine (62.9%) survived. Nine (14.5%) were diagnosed to have COVID-19, of whom four survived. There was a significant correlation between COVID-19 disease and a history of alcohol consumption ( = 0.036; odds ratio 1.7; 95% confidence interval, 1.3-2.2). Univariate analysis showed significant differences between infected and noninfected patients regarding their urea and time for first and second hemodialysis sessions, as well as the duration of ethanol administration.

Conclusions: In conclusion, during the pandemic, specific attention should be paid to patients with a history of alcohol ingestion and elevated creatinine, loss of consciousness, and severe acidosis as these signs/symptoms could be present in both COVID-19 and methanol poisoning, making differentiation between the two challenging.

Sudden Cardiac Arrest in an Asymptomatic Zinc Phosphide-Poisoned Patient: A Case Report.

Cardiovasc Toxicol 2020 10;20(5):525-530

Social Determinants of Health Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Zinc phosphide is a gray to black powder mainly used as a rodenticide. In contact with gastric fluid, it releases phosphine which is the main toxic material of this compound. Phosphine interferes with oxidative respiratory cycle of the cells, but is generally expected to manifest its toxicity with prodromal signs and symptoms including abdominal pain, nausea and vomiting, metabolic acidosis, and increased liver function tests. A 64-year-old man was referred to our center with the history of ingestion of three full table spoons of zinc phosphide powder with only a mild GI discomfort. Abdominal X-ray revealed radiopaque material in epigastric and abdominal right upper quadrant. Despite treatment with polyethylene glycol and completely normal vital signs and lab tests, he experienced sudden cardiac arrest 19 h after admission. Autopsy showed clues of focal myopathy and fibrosis with evidences of ischemia and congestion in cardiac tissue, pulmonary edema, shrunken bilateral kidneys, and nutmeg yellow liver. Toxicology panel confirmed the presence of phosphine and zinc phosphide in the gastric fluid. The patient deteriorated suddenly despite being completely symptom-free during the hours preceding cardiovascular arrest. Since the cardiopulmonary injury is the most rampant cause of early death, checking of the cardiac enzymes and cardiac monitoring could be beneficial for early detection and efficient management of these patients.

Lead poisoning; a neglected potential diagnosis in abdominal pain.

BMC Gastroenterol 2020 May 6;20(1):134. Epub 2020 May 6.

University of Colorado Anchutz Medical Campus, Rocky Mountain Poison & Drug Safety, Denver, CO and Washington Poison Center, Seattle, WA, USA.

Background: Abdominal pain may be a presenting symptom of lead poisoning and is often difficult to diagnose. This study aimed to determine the prevalence of abdominal pain in patients seen in the Laghman Hakim Hospital ED and GI clinic who were lead-intoxicated, with or without opiate use disorder.

Methods: Between July 2017 and January 2018, patients seen in the ED and GI clinic of Loghman Hakim Hospital with unexplained abdominal pain or abdominal pain resistant to treatment were enrolled. Informed consent was obtained from potential enrollees. For standardization, a pre-designed data collection tool was developed for uniform data acquisition. Opiate use was determined historically. For this study, lead poisoning was defined as a blood lead level (BLL) greater than or equal to 30 μg/dL (1.45 μmol/L) with concomitant GI symptoms.

Results: Of 125 patients admitted, 28 (22.4%) had BLLs higher than 30 μg/dL. None of the patients had signs and symptoms of opioid withdrawal syndrome during evaluation. Elevated BLLs were significantly correlated with oral opium use/abuse, history of addiction for over the preceding 12 years. The daily opium use was more than 2.75 g. There was a statistical correlation between lead toxicity and abdominal pain consistency and intensity, constipation, and paresthesias. Anemia, leukocytosis, and abnormal liver enzyme tests were laboratory findings associated with lead toxicity. Four patients died, one of whom was diagnosed with lead toxicity.

Conclusion: Lead toxicity should be considered in the potential differential diagnosis of severe and resistant abdominal pain in patients referring to general EDs or GI clinics if a positive history of opium abuse exists.

Acute versus chronic methotrexate poisoning; a cross-sectional study.

BMC Pharmacol Toxicol 2019 07 3;20(1):39. Epub 2019 Jul 3.

School of Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Background: Data is limited on comparison of acute and chronic methotrexate (MTX) poisoning. Methotrexate is an anti-folate drug that may be prescribed in some malignant or chronic inflammatory conditions. The aim of the current study was to compare signs and symptoms, complications, treatment and final outcome of acute and chronic MTX toxicity.

Method: In a retrospective study in a referral center between March 2010 and March 2018, all patients who had been referred with the history of MTX poisoning and hospitalized due to acute or chronic poisoning were evaluated and compared.

Results: Of the total 27 patients admitted during the study period, 13 had referred with acute (group 1; consumption of MTX for less than 7 days) and 14 had referred with chronic toxicity (group 2; consumption of MTX for more than 7 days). Mean age was significantly higher in the second group (P < 0.001). Median total dose of MTX was similar between the groups (P = 0.90). Mucosal ulcers and skin lesions (P < 0.001 and 0.02, respectively) were the only symptoms significantly different between the two groups. Leukopenia (P < 0.001), thrombocytopenia (P < 0.001), and anemia (P = 0.04) were significantly more common in the second group. Blood urea nitrogen and creatinine were also significantly higher in the second group of the patients (P < 0.001 and P = 0.048). Median leucovorin administered dose was 200 mg [14, 480] versus 150 mg [75, 187] (P = 0.69) in groups 1 and 2, respectively.

Conclusions: Chronic MTX poisoning is more serious than acute toxicity and accompanies higher dermatologic, hematologic, and hepatic complications necessitating more aggressive treatments including administration of higher doses of leucovorin or bone marrow stimulants such as G-CSF. This may be attributable to the underlying diseases and features (including older ages) which predispose these patients to complications.
