Post-SARS osteonecrosis and anticardiolipin antibodies / 中国矫形外科杂志

ABSTRACT

[Objective]To explore the correlation between anticardiolipin antibodies and post-SARS patients with osteonecrosis,investigate the etiology of post-SARS osteonecrosis,and select the sensitive molecular symbols for early diagnosis and distinguish the high risk population.[Method]The studied subjects were divided into two groups.Sixty-two post-SARS patients with osteonecrosis was one group,and 52 matched healthy people was as normal controlled group.Empty stomach blood samples from cubital veins were collected from both groups.IgA,IgG and IgM of anticardiolipin antibodies types were examined by ELISA.[Result]Twenty-one of 62 post-SARS osteonecrosis patients were tested at least one type of anticardiolipin antibodies positive,among them,with IgA(11.33?11.209)APL,IgG(5.127?5.927)GPL,IGM(17.821?10.606)MPL.Four of 52 control group persons were detected positive,with IGA(10.702?3.126)APL,IgG(5.184?4.780)GPL,IgM(14.684?5.516)MPL.There were significant differences between two groups,while,there were no difference in prothrombin time(PT),thrombin time(TT),prothrombin activity(PTA)and international normalized ratio(INR).[Conclusion]The study indicates an increased positive incidence of anticardiolipin antibodies in post-SARS patients with osteonecrosis.This has reflected that anticardiolipin antibodies may play a role in osteonecrosis.
