To investigate the possible relationship between circulating oxLDL and oxLDL Ab concentrations in order to better understand the role of oxLDL Ab in atherosclerosis.
Design
In a cross-sectional study of 86 patients undergoing ultrasonographic scanning of the carotid artery, concentration of circulating oxLDL and oxLDL Ab were determined by ELISA. For multivariate analysis, we also measured many conventional cardiovascular risk factors. Spearman’s rank correlation test and chi-square test were used to evaluate the correlation between circulating oxLDL and oxLDL Ab. A stepwise multiple regression analysis and Logistic regression analysis were used to study the influencing factors.
Results
There was no linear correlation between circulating oxLDL and oxLDL Ab. Circulating oxLDL was influenced by HDL, systolic blood pressure and body mass index, while only TC was independent factor associating with oxLDL Ab.
Conclusions
The present study showed that oxLDL was present at a low concentration in the circulation, and that plasma oxLDL had no linear correlation with oxLDL antibodies. However, the issue still needs further study.
