Lethal case of myocardial ischemia following overdose of the synthetic cannabinoid ADB-FUBINACA.
    Legal medicine (Tokyo, Japan), 2022, Volume: 54

    The serious adverse effects of synthetic cannabinoids (SCB), the lack of human pharmacological data on SCBs, and the increasing number of SCBs with diverse structures are growing public health concerns. A fatal case of myocardial ischemia after ADB-FUBINACA overdose is reported. A 41-year-old male died after consuming a brown, powder-like drug. Autopsy revealed pallor in the left ventricle of the subendocardial two-third of the myocardium, and histological examination revealed early signs of myocardial ischemia: few wavy myocardial fibers, contraction band necrosis in the subendocardial region, and patchy subendocardial complement component 9 (C9) positivity. Toxicological analysis detected a high concentration of the indazole carboxamide derivative SCB ADB-FUBINACA (peripheral blood: 105 ng/mL) and a low concentration of the synthetic cathinone (SC) derivative stimulant N-ethylpentylone (NEP). The literature concerning ADB-FUBINCA overdoses is reviewed, and the possible mechanism of death and the cardiac effects of SCBs are discussed. Effects of SCBs are unpredictable, but they are potentially cardiotoxic, capable causing arrhythmias, cardiac hypertrophies, and myocardial ischemia. The cardiotoxicity of SCBs can be attributed to vasospasms, decreased myocardial contractility, and increased cardiac workload and oxygen demand. Based on the autopsy, histology, and toxicology, it could be reasonably suggested, that ADB-FUBINACA have been a significant contributor to the myocardial ischemia seen in histology. The mechanism of death was likely fatal arrhythmia induced by the patchy myocardial ischemia. Due to the low concentration of NEP, it's role in the fatal outcome is improbable.

Fatal intoxication of a regular drug user following N-ethyl-hexedrone and ADB-FUBINACA consumption.
    Journal of forensic and legal medicine, 2019, Volume: 65

    In Hungary, N-ethyl-hexedrone (NEH) was the most frequently seized stimulant designer drug in 2017, while among synthetic cannabinoids ADB-FUBINACA and AB-FUBINACA were the most popular. Symptoms of intoxication by these substances are well known but less is known about the pathology of overdose-related death. NEH-induced fatal intoxication has not been described in the literature and knowledge surrounding the particular circumstances of death could be useful better public education of risk and more adequate treatment of overdose patients. In this report, we characterize the case of a 23-year-old male regular drug user who died a few hours after NEH and ADB-FUBINACA consumption. His medical history showed arrhythmia in childhood, and some seizures. Autopsy found he had a BMI of 42.9, a hypertrophic and dilated heart, severe atherosclerosis of the valves, coronaries and the arteries, and edema of the internal organs. Histology confirmed those findings. Postmortem blood levels of NEH were 285 ng/ml, along with 0.08 ng/ml ADB-FUBINACA and five ADB-FUBINACA metabolites. Based on the blood concentrations measured in suspected drug users (≤83.9 ng/ml) we hypothesize that NEH intoxication was the cause of death in this case, with heart disease being a co-factor and that the synthetic cannabinoid effect might have been accompaniment. This case also offered the opportunity to identify the metabolites of ADB-FUBINACA in the blood. We identified metabolites in the post-mortem blood by comparing them to human liver microsomal enzyme metabolites in vitro. Three major and two minor metabolites were found in the blood, of which two could only be derived from ADB-FUBINACA, as opposed to other cannabinoids. The case highlights the importance of the complex analysis of drug related deaths by medico-legal autopsy, histopathology and toxicology.

Supraventricular tachycardia and acute confusion following ingestion of e-cigarette fluid containing AB-FUBINACA and ADB-FUBINACA: a case report with quantitative analysis of serum drug concentrations.
    Clinical toxicology (Philadelphia, Pa.), 2017, Volume: 55, Issue:7

    AB-FUBINACA and ADB-FUBINACA are structurally similar synthetic cannabinoids with potent CB. To report a case of supraventricular tachycardia and acute confusion after ingestion of e-cigarette fluid containing AB-FUBINACA and ADB-FUBINACA, with quantitative analysis of the serum drug concentrations.. A healthy 24-year-old man ingested two drops of e-cigarette fluid which were later found to contain AB-FUBINACA and ADB-FUBINACA. Within 30 min of ingestion, he became somnolent, confused, and agitated, with palpitation and vomiting. On arrival to the emergency department, a short run of supraventricular tachycardia was noted, which resolved spontaneously. Bedside urine immunoassay failed to detect recreational drugs. Laboratory blood tests showed mild hypokalemia. Exposure to AB-FUBINACA and ADB-FUBINACA was confirmed analytically, with serum concentrations of 5.6 ng/mL and 15.6 ng/mL, respectively, in the blood sample collected on presentation. The patient recovered uneventfully with supportive treatment and was discharged 22 h after admission.. AB-FUBINACA and ADB-FUBINACA are orally bioavailable with rapid onset of toxicity after ingestion. In this case, supraventricular tachycardia was likely the result of exposure to AB-FUBINACA and ADB-FUBINACA. The serum concentrations of AB-FUBINACA and ADB-FUBINACA were higher than those previously reported in fatal cases.. In the context of acute poisoning, the presence of unexplained tachyarrhythmias, confusion, and a negative recreational drug screen should prompt clinicians to consider synthetic cannabinoid toxicity as a differential diagnosis.
