Biomarcadores sanguíneos, de orina y conductas autolesivas e intentos de suicidio repetidos en los adolescentes / Blood and urine biomarkers and repeated self-injurious behaviors and suicide attempts in adolescents

Hay evidencia parcial de que los niveles elevados de la β-endorfina sanguínea se asocian a la adicción suicida en los adultos, pero apenas hay datos sobre los adolescentes. La β-endorfina sanguínea, con un importante papel en los mecanismos de gestión de las adicciones, puede inducir euforia y felicidad, recompensar y reforzar el comportamiento suicida. Para probar si los grandes repetidores de intentos de suicidio (5 o más intentos de suicidio) y de conductas autolesivas (20 o más episodios de autolesiones) tienen unos niveles de biomarcadores más elevados, se selecciona una muestra de 43 pacientes de entre 12 y 17 años que acuden al Servicio de Urgencias Psiquiátricas en el Hospital Universitario Puerta de Hierro Majadahonda. Diez presentan 5 o más intentos de suicidio, 35 presentan 20 o más episodios autolesivos y 10 presentan ambas características, y la mayoría de los adolescentes cumplían criterios de adicción para autolesiones y suicidio. Los resultados sugieren que todos los pacientes que presentaban adicción al suicidio también presentaban adicción a la autolesión. Los niveles de ACTH, cortisol y β-endorfina sanguíneos y de cortisol en orina fueron muy elevados, pero no diferenciaban a los grandes repetidores del resto de adolescentes. (AU)

There is partial evidence that elevated levels of blood β-endorphin are associated with suicidal addiction in adults, but hardly any data on adolescents. Blood β-endorphin, with an important role in addiction management mechanisms, can induce euphoria and happiness, reward and reinforce suicidal behavior. To test whether high repeaters of suicide attempts (5 or more suicide attempts) and self-injurious behaviors (20 or more episodes of self-injury) have higher biomarker levels, a sample of 43 patients aged 12-17 years attending the Psychiatric Emergency Department at the Hospital Universitario Puerta de Hierro Majadahonda is recruited. Ten present 5 or more suicide attempts, 35 present 20 or more self-injurious episodes and 10 present both characteristics, and most of the adolescents meet addiction criteria for self-injury and suicide. The results suggest that all patients with addiction to suicide also had addiction to self-injury. Blood ACTH, cortisol and β-endorphin and urine cortisol levels were very elevated, but did not differentiate heavy repeaters from the rest of the adolescents. (AU)

Biosignature of self-injury behaviors in adolescence: Role of ß-endorphin in an acute inpatient unit.

Self-injurious behavior (SIB) (either non-suicidal self-injury, NSSI; or suicide attempts, SA) is a common reason for adolescent psychiatric emergency hospitalizations. Altered basal serum ß-endorphin (BE) levels have been reported in adults with a history of SIB, but information is lacking in adolescents. We analyzed the psychoclinical profile and serum BE level of 39 adolescents admitted to the acute unit at a hospital in Spain due to SIB. The Mean (SD) serum BE level was high (190.53 ± 74.83). Regarding time sequence, the onset age of NSSI and SA were related (p < 0.001). The older the onset age of NSSI, the shorter the transition between NSSI and the onset of SA behavior (p = 0.05), but this difference does not lead the variation of BE (p = 0.81). Patients diagnosed with depression had lower serum BE levels than adolescents with other diagnoses (p = 0.03). Although adolescents who seem to be addicted to SIB had higher levels of BE, this finding was not statistically significant. The relationship between serum BE levels and SIB in adolescents requires further investigation.

Demand Analysis of a Psychiatric Emergency Room and an Adolescent Acute Inpatient Unit in the Context of the COVID-19 Pandemic in Madrid, Spain.

Introduction: COVID-19 represents a serious threat to mental health worldwide. The aim of this study is to identify changes in adolescent psychiatry treatment demand in a tertiary hospital in Madrid during the first month (March 11 to April 11) after the pandemic declaration by the World Health Organization (WHO). We hypothesized that fear of contagion within COVID-19 may deter people from asking for psychiatric care. Method: The current study is retrospective, observational, and transversal. We reviewed the clinical records of 89 adolescents who went to the Emergency Room (ER) or were hospitalized at the Acute Inpatient Unit (AIU) at the Puerta de Hierro University Hospital-Majadahonda (PHUH-M) between March 11 and April 11. Socio-demographic, clinical, and demand variables were included in the study. Chi-square or Fisher exact tests were performed to compare categorical variables. We used the U Mann-Whitney test to compare quantitative variables. The level of statistical significance was set at p< 0.05. Analyses were conducted using SPSS v11.0. Results: The number of adolescents demanding psychiatric care at the ER dropped from 64 adolescents in 2019 to 25 in 2020. Similarly, psychiatric demand collapsed from 31 to 18 patients when comparing 2019 and 2020. Furthermore, the average hospital stay in 2020 trended toward a decrease when compared to 2019 (8.94 ± 4.87 vs. 14.32 ±10.23, p = 0.08). Self-injurious thoughts and behaviors were the most predominant reasons for consultation at both ER and AIU. Conclusion: The demand for adolescent psychiatric care decreased in the first month after the declaration of the pandemic. Our findings may be explained by (1) the fear of contagion, (2) the strict confinement measures, and (3) the initial shock as an adaptive reaction described in other disasters. Further studies are needed.
