摘要
objective: to assess blood levels of hyperhomocysteinaemia, vitamin e, selenium, copper, ceruloplasmin and ferritin in patients with diagnosis of ischemic stroke (is). methods: 104 patients with the diagnosis of is and 98 healthy controls had blood homocysteine, vitamin e, selenium, copper, ceruloplasmin and ferritin analyzed. homocysteine and vitamin e were analyzed by high performance liquid chromatography, selenium by inductively coupled plasma - mass spectrometry, copper by colorimetry, ceruloplasmin by nefelometry and ferritin by enzyme linked fluorescent assay. statistics was performed with studentˋs t test and analysis of variance. results: frequency of hyperhomocysteinaemia was 43% for patients and 13% for controls. concentrations of vitamin e, copper, ceruloplasmin and ferritin were significantly higher in patients. differences in selenium levels were not statistically significant. discussion: hyperhomocysteinaemia levels were higher than those found in literature, possibly due to populationˋs genetics or its nutritional habits. as to vitamin e, selenium, copper, ceruloplasmin and ferritin, our results match some published papers but this studyˋs model cannot stablish whether vitamin e and selenium levels were changed by is or by new habits acquired by the patients. ferritin and ceruloplasmin can be a marker for is instead of causative agent of its pathogenesis. conclusion: hyperhomocysteinaemia is more prevalent in patients with is diagnosis. higher levels of vitamin e, copper, ceruloplasmin and ferritin found in patients cannot be imputed to is.
