Abstract

Introduction: Chronic non-recreational use of methamphetamine (shabu) is increasing among the Filipino population in Barcelona. The Asian population presents a different stroke pattern, with a higher incidence of haemorrhage, and different vascular risk factors and health behaviours. The objective of this study is to describe the stroke profile and incidence of methamphetamine use in patients of Filipino origin admitted to our centre.

Patients and methods: Demographic data, vascular risk factors, clinical data and prognosis were recorded. Methamphetamine exposure was analysed in plasma samples collected on admission, which were then analysed by liquid chromatography-mass spectrometry.

Results: Of a total of 6,418 stroke patients, 73 (1.1%) were identified as being of Filipino origin. The mean age was 54.4 ± 12.1 years, 54% were male and the stroke was ischaemic in 64.4% of cases. Arterial hypertension was the main risk factor. Ten (13.7%) patients tested positive for methamphetamine and amphetamine. These results confirm recent substance use prior to the stroke, mostly in men (80%). In patients who were consumers, 60% had a haemorrhagic stroke, with a poor functional prognosis at three months in 55.6% of patients.

Conclusions: In our setting, patients of Filipino ethnicity admitted for stroke related to the consumption of shabu belonged a younger age bracket, with a lower prevalence of vascular risk factors and a predominance of the haemorrhagic subtype. Methamphetamine testing in Filipino stroke patients is recommended due to the high prevalence of methamphetamine use in our country.

Title: Perfil clínico y abuso de metanfetamina no recreativa (shabú) entre los pacientes con ictus en la población filipina.

Introducción. En la población filipina de Barcelona está aumentando el consumo crónico no recreativo de metanfetaminas (shabú). La población asiática presenta un patrón de ictus diferente, con mayor incidencia de hemorragias, y diferentes factores de riesgo vascular y conductas de salud. El objetivo es describir el perfil de ictus e incidencia de consumo de metanfetaminas en pacientes de origen filipino ingresados en nuestro centro. Pacientes y métodos. Se registraron datos demográficos, factores de riesgo vascular, datos clínicos y pronóstico. Se analizó la exposición a metanfetamina en muestras de plasma recogidas en el ingreso, que se analizaron por cromatografía líquida-espectrometría de masas. Resultados. Del total de 6.418 pacientes con ictus, se identificó a 73 pacientes filipinos (1,1%). La edad media era de 54,4 ± 12,1 años, el 54% eran hombres y el ictus era isquémico en el 64,4%. La hipertensión arterial fue el principal factor de riesgo. Diez (13,7%) pacientes dieron positivo a metanfetamina y anfetamina. Estos resultados confirman un consumo reciente de sustancias previo al ictus, principalmente en hombres (80%). En pacientes consumidores, un 60% presentaba un ictus hemorrágico, con mal pronóstico funcional a tres meses en el 55,6% de los pacientes. Conclusiones. En nuestro medio, los pacientes de etnia filipina ingresados por ictus en relación con consumo de shabú presentaron un perfil de edad más joven, con menor prevalencia de factores de riesgo vascular y predominio del subtipo hemorrágico. Se recomienda la determinación de metanfetamina en los pacientes filipinos con ictus debido a la alta prevalencia del consumo de metanfetamina en nuestro país.
