The results showed that the ACA in CI and CH patients was significantly higher than in controls and IgG ACA was the most important isotype. Stroke in ACA positive group tended to be recurrent and of multi focuses. Positive rate of IgG ACA reached its peak within the first week after stroke onset. The results suggested that ACA was an independent risk factor in CI and CH and might be valuable in stroke prediction.展开更多

Results The ACA positive rate was 17.1% among the 146 renal transplant recipients,and that of the control group was 6.3%.There was no significant difference.However,the ACA positive rate of the renal transplant recipients infected with CMV was 31.2%.It was clearly higher than that of those with no infection of CMV and that of the control group ( P <0.005). Conclusion The production of ACA was closely related to CMV infection.It might be one of the factors of chronic angiopathy of the transplanted kidney due to CMV infection.展开更多

This cross-sectional study assessed the frequency of IgG, IgM, and IgA ACA in type 2 diabetics with and without history of vascular events for the last 5 years, and in healthy controls. ACA were detected by enzyme immunoassay. A total of 73 type 2 diabetics (33 with history of vascular events) and 54 healthy controls were tested. Most diabetics were female (p = 0.003), and older than controls (p 0.09). ACA positivity rates were also similar when diabetics with and without history of vasculopathy were compared (p > 0.47). After adjusting for gender, age, hypertension, and smoking status, a weak but statistically insignificant association between IgM ACA and diabetics with vasculopathy was found (adjusted OR 2.7;95% CI 0.2 - 34.2;p = 0.441). Overall, levels of IgG (r = 0.25;p = 0.005) and IgM (r = 0.23;p = 0.010) ACA were associated with increasing age. In short, the frequency of a positive ACA test in type 2 diabetics (with or without previous macrovasculopathy) was not significant as compared to healthy controls. There was no association of ACA with vascular events in patients with type 2 diabetes.展开更多
