摘 要:[目的]測定嚴重急性呼吸系統綜合徵(severe acute respiratory syndrome,SARS)後骨壞死患者的抗心磷脂抗體,探討SARS後骨壞死的病因學,以便用於非創傷性骨壞死的早期診斷和易感人羣的篩選。[方法]取62例SARS後骨壞死患者抽取空腹肘靜脈血,另取健康人羣52名爲對照,應用酶聯免疫吸附法測定抗心磷脂抗體的IgA、IgG和ISM,並檢測血漿凝血酶原時間(PT)和凝血酶時間(TT),凝血酶原活動度(PTA)和國際標準化值(INR)4項常規出凝血檢查。[結果]SARS後骨壞死患者抗心磷脂抗體陽性者多見。骨壞死組62人中有21人出現抗心磷脂抗體陽性,佔339%,其中IgA(1133±11209)APL,IgG(5127±5927)GPL,IgM(17821±10606)MPL。對照組52人中僅有4人出現異常,佔77%,其中IgA(10702±3126)APL,IgG(5184±4780)GPL,IgM(14684±5516)MPL,經獨立樣本t檢驗和卡方檢驗處理,兩組之間有顯著性差異(P<005)。血漿凝血酶原時間(PT)和凝血酶時間(TT),凝血酶原活動度(PTA)和國際標準化值(INR)4項常規出凝血檢查兩組之間無顯著性差異。[結論]SARS後骨壞死患者的抗心磷脂抗體陽性率增多,抗心磷脂抗體可能在骨壞死發生中起作用。

Abstract:[Objective]To explore the correlation between anticardiolipin antibodies and postSARS patients with osteonecrosis,investigate the etiology of postSARS osteonecrosis,and select the sensitive molecular symbols for early diagnosis and distinguish the high risk population[Method]The studied subjects were divided into two groupsSixtytwo postSARS patients with osteonecrosis was one group,and 52 matched healthy people was as normal controlled groupEmpty stomach blood samples from cubital veins were collected from both groupsIgA,IgG and IgM of anticardiolipin antibodies types were examined by ELISA[Result]Twentyone of 62 postSARS osteonecrosis patients were tested at least one type of anticardiolipin antibodies positive,among them,with IgA(1133±11209)APL,IgG(5127±5927)GPL,IGM(17821±10606)MPLFour of 52 control group persons were detected positive,with IGA(10702±3126)APL,IgG(5184±4780)GPL,IgM(14684±5516)MPLThere 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 postSARS patients with osteonecrosisThis has reflected that anticardiolipin antibodies may play a role in osteonecrosis

非創傷骨壞死的病因和發病機理尚不十分清楚,目前認爲血管內凝血使骨內血管阻塞,導致骨循環的中斷和骨細胞的`缺血是骨壞死的共同通路。有文獻報道骨壞死的發生與患者的高凝低纖溶狀態有關〔1〕,而抗心磷脂抗體是與血栓形成密切相關的異質性自身抗體,作者對SARS後骨壞死患者的血清抗心磷脂抗體進行檢測,探討抗心磷脂抗體與骨壞死發生是否具有相關性。
1 材料與方法
在2003年春的嚴重急性呼吸系統綜合徵(severe acute respiratory syndrome,SARS)感染患者中,作者於2003年12月~2004年2月進行全身多關節(雙髖、雙膝、雙踝、雙肩、部分患者加雙腕)MRI影像學普查,研究對象爲62例發生骨壞死患者,其中男性25例,女性37例;平均302歲(20~60歲)。激素(摺合成甲強龍)使用量平均6 2508 mg(1 500~25 600mg),每日最大劑量平均3445 mg(80~860 mg),使用時間平均421 d(16~102 d),其中股骨幹壞死1例,單純股骨頭壞死16例(單側4例,雙側12例),單純膝關節壞死7例(單側3例,雙側4例),多關節壞死38例,對照組取正常健康人羣52例,男性22例,女性33例,平均351歲(15~61歲)。
