Clinical effects of cannabis compared to synthetic cannabinoid receptor agonists (SCRAs): a retrospective cohort study of presentations with acute toxicity to European hospitals between 2013 and 2020.

INTRODUCTION: Cannabis is the most common recreational drug worldwide and synthetic cannabinoid receptor agonists are currently the largest group of new psychoactive substances. The aim of this study was to compare the clinical features and outcomes of lone acute cannabis toxicity with lone acute synthetic cannabinoid receptor agonist toxicity in a large series of presentations to European emergency departments between 2013-2020. METHODS: Self-reported drug exposure, clinical, and outcome data were extracted from the European Drug Emergencies Network Plus which is a surveillance network that records data on drug-related emergency department presentations to 36 centres in 24 European countries. Cannabis exposure was considered the control in all analyses. To compare the lone cannabis and lone synthetic cannabinoid receptor agonist groups, univariate analysis using chi squared testing was used for categorical variables and non-parametric Mann-Whitney U- testing for continuous variables. Statistical significance was defined as a P value of < 0.05. RESULTS: Between 2013-2020 there were 54,314 drug related presentations of which 2,657 were lone cannabis exposures and 503 lone synthetic cannabinoid receptor agonist exposures. Synthetic cannabinoid receptor agonist presentations had statistically significantly higher rates of drowsiness, coma, agitation, seizures and bradycardia at the time of presentation. Cannabis presentations were significantly more likely to have palpitations, chest pain, hypertension, tachycardia, anxiety, vomiting and headache. DISCUSSION: Emergency department presentations involving lone synthetic cannabinoid receptor agonist exposures were more likely to have neuropsychiatric features and be admitted to a psychiatric ward, and lone cannabis exposures were more likely to have cardiovascular features. Previous studies have shown variability in the acute toxicity of synthetic cannabinoid receptor agonists compared with cannabis but there is little comparative data available on lone exposures. There is limited direct comparison in the current literature between lone synthetic cannabinoid receptor agonist and lone cannabis exposure, with only two previous poison centre series and two clinical series. Whilst this study is limited by self-report being used to identify the drug(s) involved in the presentations, previous studies have demonstrated that self-report is reliable in emergency department presentations with acute drug toxicity. CONCLUSION: This study directly compares presentations with acute drug toxicity related to the lone use of cannabis or synthetic cannabinoid receptor agonists. It supports previous findings of increased neuropsychiatric toxicity from synthetic cannabinoid receptor agonists compared to cannabis and provides further data on cardiovascular toxicity in lone cannabis use.

Ketamine detection in urine samples from patients poisoned by recreational drugs: epidemiologic, clinical, and toxicologic profiles. / Detección de ketamina en pacientes intoxicados por drogas recreativas: perfil epidemiológico, clínico y toxicológico.

OBJECTIVES: To describe the epidemiologic, clinical, and toxicologic profiles of patients who used recreational ketamine and experienced acute poisoning. MATERIAL AND METHODS: Retrospective observational study of patients attended by several emergency medical services in the Balearic Islands for analytically confirmed acute poisoning after using ketamine between January 2016 and December 2020. Urine samples were analyzed by immunoassay and combined gas chromatography and mass spectrometry. RESULTS: One hundred twenty-two patients were studied. The mean (SD) age was 26.7 (6.5) years. The majority were men (77.9%) and not residents of the Balearic Islands (74.6%). Poisoning cases occurred mainly in the summer and in the island of Ibiza (84.4%). Ketamine use was declared by the patient or clinically suspected in 40.2%. The most common clinical signs were tachycardia (43.4%), hypertension (28.7%), mydriasis (27.0%), altered consciousness (25.4%), agitation/aggressiveness (25.4%), and hypothermia (21.3%). Seven patients (5.73%) required admission to the intensive care unit. The drugs most often detected along with ketamine were cocaine, in 93.4%, and 3,4-methylenedioxymethamphetamine (MDMA), in 78.7%. Multiple-drug use combining ketamine, cocaine, and MDMA, or on occasion additional substances, was detected in 98.4%. CONCLUSION: Detection of ketamine in urine samples from patients poisoned by recreational drugs is associated with a characteristic profile: young men who are not residents of the Balearic Islands, who attend electronic music concerts, and who have taken multiple drugs. A substantial percentage of such patients are unaware of drug intake.

OBJETIVO: Identificar el perfil epidemiológico, clínico y toxicológico de los pacientes consumidores de ketamina en el contexto de una intoxicación aguda por drogas recreativas. METODO: Estudio observacional retrospectivo en pacientes atendidos en varios servicios de urgencias (SU) en Baleares por intoxicaciones agudas por drogas recreativas con exposición a ketamina confirmada analíticamente, entre enero de 2016 y diciembre de 2020. El análisis toxicológico en muestras de orina se realizó mediante inmunoensayo y cromatografía de gases acoplada a espectrometría de masas. RESULTADOS: Se incluyeron 122 pacientes. La edad media fue de 26,7 (DE 6,5) años. La mayoría eran hombres (77,9%) y no residentes en las Islas Baleares (74,6%). Los casos se detectaron mayoritariamente en verano y en Ibiza (84,4%). El uso de ketamina solo fue declarado por el paciente o fue clínicamente sospechado por el médico en el 40,2%. Los signos clínicos más frecuentes fueron taquicardia (43,4%), hipertensión (28,7%), midriasis (27,0%), disminución de la consciencia (25,4%), agitación/agresividad (25,4%) e hipotermia (21,3%). Siete pacientes (5,7%) requirieron ingreso en la unidad de cuidados intensivos (UCI). La cocaína (93,4%) y la 3,4-metilendioximetanfetamina (MDMA) (78,7%) fueron las drogas más detectadas junto con la ketamina. El policonsumo fue habitual (98,4%), combinando ketamina, cocaína y MDMA, en algunos casos asociado a otras sustancias. CONCLUSIONES: La detección de ketamina en intoxicaciones por drogas recreativas se asocia a consumidores con un perfil característico (varones jóvenes, no residentes, asistentes a eventos de música electrónica y policonsumo) y un alto porcentaje desconocen de este consumo.

Manifestaciones clínicas y eventos adversos graves tras consumo de cannabis: efecto de la edad y análisis diferenciado en función del sexo y la coingesta de etanol / Clinical manifestations and serious adverse effects after cannabis use: role of age according to sex and coingestion of alcohol

Objetivo. Investigar si existen diferencias en las manifestaciones clínicas por consumo de cannabis según la edad, y si estas se modifican en función del sexo o el consumo de etanol. Método. Estudio observacional descriptivo de pacientes atendidos en 11 servicios de urgencias con consumo de can- nabis como motivo de consulta. Se recogieron 11 manifestaciones clínicas y se analizó su frecuencia relativa en fun- ción de la edad mediante curvas spline cúbicas restringidas. Se analizó si existía interacción en el comportamiento etario de cada uno de los síntomas en función del sexo y del consumo de etanol. Resultados. Se analizaron 949 pacientes, edad media 29 años, 74% varones y 39% con coingesta de etanol. Se iden- tificaron tres patrones de síntomas según la edad: estable (vómitos, cefalea, convulsiones, hipotensión), incrementada en edades medias (agresividad-agitación, ansiedad, psicosis, palpitaciones, alucinaciones) y con aumento progresivo con la edad (dolor torácico e hipertensión). En la relación síntoma-edad, la frecuencia de palpitaciones, vómitos y ce- falea tuvo un comportamiento significativamente diferente según el sexo, más constante en hombres y con un incre- mento marcado en edades medias en mujeres. La coingesta de etanol se asoció con más agitación-agresividad (34,0%/23,4%, p < 0,001) y menos palpitaciones (9,8%/15,6%, p = 0,01), ansiedad (20,7%/27,8%, p = 0,01), psico- sis (10,3%/16,6%, p = 0,007) y dolor torácico (3,8%/9,5%, p = 0,001). En cuanto a la relación síntoma-edad, el eta- nol solo modificó significativamente la frecuencia de vómitos y de psicosis. Conclusión. La edad condiciona efectos clínicos diferenciales en algunas manifestaciones agudas de la intoxicación por cannabis que precisa asistencia hospitalaria, y el sexo y el consumo simultáneo de alcohol modifican esta relación entre edad y frecuencia de algunos síntomas.

Objectives. To study whether there are age-related differences in the clinical effects of cannabis poisoning and whether any age differences found are also related to sex or coingestion of alcohol. Methods. Descriptive observational study of patients treated in 11 emergency departments for symptoms related to cannabis use. We collected data on 11 clinical manifestations and used a restricted cubic spline model to analyze their relative frequency according to age. We also looked for any interactions between the findings and patient sex or alcohol coingestion. Results. A total of 949 patients were studied. The mean age was 29 years, 74% were males, and 39% had also consumed alcohol. We identified 3 symptom patterns related to age. One set of symptoms (vomiting, headache, convulsions, and hypotension) remained stable across all ages. Manifestations that increased in the middle of the age range studied were agitation and aggressivity, psychosis, palpitations and hallucinations. Chest pain and hypertension increased in older-aged patients. The frequencies of palpitations, vomiting, and headache differed according to sex. These manifestations held constant in males but were markedly higher in young-adult females. Coingestion of alcohol was associated with agitation and aggressivity (in 34.0% vs 23.4%, P < .001), fewer reports of palpitations (in 9.8% vs 15.6%, P = .01), less anxiety (in 20.7% vs 27.8%, P = .01), less psychosis (in 10.3% vs 16.6%, P = .007), and less chest pain (in 3.8% vs 9.5%, P = .001). The only significant interaction between age and alcohol coingestion occurred with respect to vomiting and psychosis. Conclusions. There are age-related differences in the acute clinical manifestations of cannabis poisoning requiring emergency hospital care. Sex and coingestion of alcohol modify the relationship between age and frequency of some manifestations. (AU)

N-acetylcysteine as an antidote for paracetamol poisoning: a multicenter study. / Estudio multicéntrico sobre el tratamiento con N-acetilcisteína como antídoto en la intoxicación por paracetamol.

OBJECTIVES: To identify the most common problems related to use of N-acetylcysteine to reverse the toxic effects of paracetamol poisoning. MATERIAL AND METHODS: Retrospective descriptive observational study of clinical records for patients treated for paracetamol poisoning in 4 emergency departments during 3 years (2017-2019). We analyzed epidemiologic, clinical, and care variables, especially those related to the suitability and safety of using N-acetylcysteine as an antidote. RESULTS: We included 332 cases of poisoning of 260 patients (78%) were over the age of 16 years, and 242 (73%) were female. Two hundred sixty-eight poisonings (81%) were the result of voluntary intake. The elimination half-life was determined in 20 cases (6%). Gastrointestinal decontamination was incorrectly prescribed on 39 occasions (28%). Treatment with the antidote was begun in 195 cases (58.7%). No serious clinical signs or symptoms were present in 282 cases (85%). The correlation of paracetamol levels in urine was stronger with the amount of drug ingested voluntarily (R2 = 0.23) than with accidental intake (R2 = 0.007). Predefined severity criteria were significantly related to reported dose ingested per body weight (P = .001) and the interval between intake and first medical assistance (P = .008). CONCLUSION: Even though clear protocols are available to guide the use of antidote treatment in cases of paracetamol poisoning, variability in fundamental aspects of management is excessive.

OBJETIVO: Conocer los aspectos clínicos relacionados con el tratamiento del antídoto N-acetilcisteína (NAC) en las intoxicaciones por paracetamol. METODO: Estudio observacional y retrospectivo de los pacientes atendidos por intoxicación por paracetamol en cuatro servicios de urgencias durante 3 años (2017-2019). Se analizan variables epidemiológicas, clínicas y asistenciales, así como la idoneidad y seguridad en el empleo del tratamiento antidótico. RESULTADOS: Se incluyeron 332 intoxicaciones: 260 casos (78%) tenían más de 16 años y 242 (73%) fueron mujeres. Doscientos sesenta y ocho intoxicaciones (81%) fueron de causa voluntaria y la semivida de eliminación se determinó en 20 ocasiones (6%). La descontaminación digestiva se indicó de forma incorrecta en 39 ocasiones (28%). Se inició tratamiento con antídoto en 195 casos (58,7%). En 282 casos (85%) no hubo ninguna clínica de gravedad. La correlación entre la dosis referida ingerida y la paracetamolemia en los casos de ingesta voluntaria (R2 = 0,23) fue más fuerte que en los casos de ingesta accidental (R2 = 0,007). Existieron diferencias estadísticamente significativas al relacionar los criterios de gravedad con la dosis referida ajustada al peso (p = 0,001) y el intervalo desde la ingesta y la primera asistencia médica (p = 0,008). CONCLUSIONES: Existe variabilidad en aspectos fundamentales del tratamiento antidótico en las intoxicaciones por paracetamol, a pesar de estar claramente protocolizado su manejo.

Circulating levels of calprotectin, a signature of neutrophil activation in prediction of severe respiratory failure in COVID-19 patients: a multicenter, prospective study (CalCov study).

OBJECTIVE: Severe COVID-19 is characterized by a dysregulated immune response in which neutrophils play a critical role. Calprotectin reflects neutrophil activation and is involved in the self-amplifying thrombo-inflammatory storm in severe COVID-19. We aimed to evaluate the role of calprotectin in early prediction of severity in COVID-19 patients. METHODS: This was a multicenter prospective observational study enrolling consecutive adult COVID-19 patients. On arrival to emergency department, blood samples were collected for laboratory tests, including serum calprotectin. The primary outcome was severe respiratory failure requiring invasive mechanical ventilation and the secondary outcome was need for Intensive Care Unit (ICU) admission. RESULTS: Study population included 395 patients, 57 (14.4%) required invasive mechanical ventilation and 100 (25.3%) were admitted to ICU. Median serum calprotectin levels were significantly higher in intubated (3.73 mg/L vs. 2.63 mg/L; p < 0.001) and ICU patients (3.48 mg/L vs. 2.60 mg/L; p = 0.001). Calprotectin showed a significant accuracy to predict the need for invasive mechanical ventilation (ROC AUC 0.723) and ICU admission (ROC AUC 0.650). In multivariate analysis, serum calprotectin was an independent predictor of invasive mechanical ventilation (OR 1.161) and ICU admission (OR 1.068). CONCLUSION: Serum calprotectin can be used as an early predictor of severity in COVID-19 patients.

Medication overdoses: changes over time. / Evolución temporal de las intoxicaciones medicamentosas.

OBJECTIVES: To review changes occurring over time in cases of medication overdose attended by an emergency department. MATERIAL AND METHODS: Retrospective review of epidemiologic and care variables related to drug poisonings in a university teaching hospital in 2007 and 2017. We used multivariate analysis to compare the 2 years. RESULTS: A total of 750 cases were included; 438 (58.4%) were from 2007. Fewer cases were seen in 2017 even though the total numbers of emergencies and poisonings had risen (P<.001). Fewer cases were suicides or suicide attempts in 2017 (P<.001), and digestive tract decontamination and antidotes were used less often (P<.001 and P=.007, respectively). Admissions (P=.004) and voluntary self-discharges or patient losses were also down in 2017 (P=.03). However, multidrug poisonings increased (P=.001), especially in the context of recreational drug use by men. Benzodiazepine overdoses accounted for most of such cases (65.1%). CONCLUSION: Medication overdoses seem to be decreasing, although the proportion of men overdosing is rising. Suicide attempts, the abuse of specific medications, and admissions also seem to be decreasing.

OBJETIVO: Análisis de la evolución temporal de las intoxicaciones medicamentosas (IM) atendidas en urgencias hospitalarias. METODO: Estudio retrospectivo, con análisis multivariante de variables epidemiológicas y asistenciales de IM, comparando la casuística de los años 2007 con 2017, en un hospital universitario. RESULTADOS: Se incluyeron 750 casos, 58,4% del 2007. En 2017, disminuyeron la causa suicida (p < 0,001), el empleo de descontaminación digestiva (p < 0,001) y antídotos (p = 0,007), y los ingresos (p = 0,004), altas voluntaria o fugas (p = 0,03). Se incrementó por el contrario la intoxicación múltiple (p = 0,001), especialmente en varones y en contexto recreativo. Las benzodiacepinas fueron los fármacos más implicados en las IM (65,1%). CONCLUSIONES: Existe una tendencia al descenso de las IM atendidas, con incremento en varones, menos intencionalidad suicida, menos uso de terapéuticas específicas y menos admisiones hospitalarias.
