ABSTRACT
SUMMARY OBJECTIVE The present study aims to investigate whether hyperhomocysteinemia (HHcy) affects the outcomes of the thrombolytic treatment for patients with AIS. METHODS A sample of 120 AIS patients were recruited and grouped according to their serum homocysteine (Hcy) levels. The National Institute of Health Stroke Scale (NIHSS) was obtained before treatment and 7 days after it to evaluate neurological outcomes; modified Rankin Scale (mRS) was obtained 12 weeks later to assess functional outcomes. Receiver operating characteristic curve (ROC) was used to demonstrate the relationship between serum Hcy level and the outcomes after tPA treatment. RESULTS The serum Hcy level of 120 patients was of 27.57±20.17μmol/L. The NIHSS scores of the patients in the low Hcy level group were remarkably lower compared to those in the high-level group (p<0.05), after 7 days of treatment. In addition, the mRS scores of the patients in the low Hcy level group, after 12 weeks, were remarkably lower compared to those in the high-level group (p<0.01). ROC demonstrated that the serum Hcy level is related to the clinical outcomes of thrombolytic treatment with moderate specificity (80.3%) and sensitivity (58.2%). CONCLUSION In conclusion, higher serum Hcy levels can indicate poorer clinical outcomes of thrombolytic treatment in patients with AIS.
RESUMO
RESUMO OBJETIVO O presente estudo tem por objetivo investigar se a hiperhomocisteinemia (HHcy) afeta os resultados do tratamento trombolítico em pacientes com AVCI agudo. METODOLOGIA Uma amostra de 120 pacientes AVCI agudo foi recrutada e agrupada de acordo com os níveis séricos de homocisteína (Hcy). Uma avaliação nos padrões do National Institute of Health Stroke Scale (NIHSS) foi obtida antes do tratamento e 7 dias após ele para avaliar desfechos neurológicos e a escala de Rankin modificada foi utilizada 12 semanas depois para avaliar os desfechos funcionais. A curva ROC (Receiver Operating Caracteristic) foi utilizada para demonstrar a relação entre os níveis séricos de Hcy e os desfechos após tratamento com t-PA. RESULTADOS Os níveis séricos de Hcy de 120 pacientes foi de 27,57±20,17μmol/L. Os escores NIHSS dos pacientes no grupo de baixo nível de Hcy foram notavelmente mais baixos em comparação àqueles do grupo de nível mais alto (p<0,05), após 7 dias de tratamento. Além disso, os escores mRS dos pacientes no grupo de baixo nível de Hcy, após 12 semanas, foram consideravelmente mais baixos em comparação com os do grupo de alto nível (p<0,01). A curva ROC demonstrou que o nível sérico de Hcy tem relação com os desfechos clínicos do tratamento trombolítico com especificidade moderada (80,3%) e sensibilidade (58,2%). CONCLUSÃO Podemos concluir então que níveis séricos mais altos de Hcy podem prever desfechos clínicos piores para o tratamento trombolítico em pacientes com AVCI agudo.
