[Clinical profile and non-recreational methamphetamine abuse (shabu) among stroke patients in the Philippine population]

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.
