A review of five years' DNA-binding antibody results in a routine service laboratory revealed 38 patients who had high DNA-binding capacity (DNA-bc) but no antinuclear antibodies (ANA). On retrospective case note analysis, 22 patients (58%) were thought to have systemic lupus erythematosus (SLE), although only six (16%) fulfilled the preliminary classification criteria of the American Rheumatism Association (ARA). Our findings indicate that ANA-negative SLE is commoner than generally realised and lead us to recommended the measurement of DNA-bc in every case where clinically appropriate.
对一家常规服务实验室五年的DNA结合抗体检测结果进行回顾发现,有38例患者DNA结合能力(DNA-bc)高但无抗核抗体(ANA)。通过回顾性病例记录分析,22例患者(58%)被认为患有系统性红斑狼疮(SLE),尽管只有6例(16%)符合美国风湿病协会(ARA)的初步分类标准。我们的研究结果表明,ANA阴性的SLE比普遍认为的更为常见,并促使我们建议在临床合适的情况下对每例患者进行DNA-bc检测。
