Sera from patients with rheumatoid arthritis (RA), patients with infectious mononucleosis (IM), and blood donors were tested by indirect immunofluorescence for the presence of antikeratin antibody (AKA), antibody to cytoskeletal intermediate filaments of prekeratin or vimentin type (AIFA) and antiperinuclear factor (APF). In 81.9% of the RA sera and 92.5% of the IM sera AIFA of IgM class was found at titres up to and in some cases exceeding 1/160. In blood donors the incidence of AIFA was 26%, at titres not exceeding 1/20. AKA and APF, always of IgG class, were found in 54.2% and 73.6% of rheumatoid sera. A weak correlation was found in RA between the incidence of AIFA and APF. AKA was not present in either IM or blood donor sera, and APF was found in only 2.5% and 3.2% of IM or blood donors respectively.
采用间接免疫荧光法检测类风湿关节炎(RA)患者、传染性单核细胞增多症(IM)患者以及献血者血清中的抗角蛋白抗体(AKA)、角蛋白前体或波形蛋白型细胞骨架中间丝抗体(AIFA)和抗核周因子(APF)。在81.9%的RA血清和92.5%的IM血清中发现IgM类AIFA,其滴度高达且在某些情况下超过1/160。在献血者中,AIFA的发生率为26%,滴度不超过1/20。AKA和APF均为IgG类,分别在54.2%和73.6%的类风湿血清中被发现。在RA中,AIFA和APF的发生率之间存在弱相关性。IM血清和献血者血清中均未检测到AKA,APF分别仅在2.5%的IM血清和3.2%的献血者血清中被发现。
