Sacroiliac joint radiographs and radionuclide sacroiliac joint uptake ratios were obtained on 14 patients with active systemic lupus erythematosus. Elevated joint ratios were found unilaterally in two patients and bilaterally in seven patients when their lupus was active. In patients whose disease became quiescent, the uptake ratios returned to normal. Two patients had persistently elevated ratios with continued clinical and laboratory evidence of active lupus. Mild sacroiliac joint sclerosis and erosions were detected on pelvic radiographs in these same two patients. There was no association between low back pain or HLA-B27 positivity and the radiographic or scintigraphic abnormalities. Elevated quantitative sacroiliac joint uptake ratios may occur as a manifestation of active systemic lupus erythematosus.
对14例活动性系统性红斑狼疮患者进行了骶髂关节X线片及放射性核素骶髂关节摄取率检查。在狼疮活动期，2例患者单侧关节摄取率升高，7例患者双侧关节摄取率升高。病情缓解的患者，摄取率恢复正常。2例患者的摄取率持续升高，并有临床及实验室证据表明狼疮仍处于活动期。在这2例患者的骨盆X线片上检测到轻度骶髂关节硬化和侵蚀。腰痛或HLA - B27阳性与X线或闪烁扫描异常之间无关联。骶髂关节定量摄取率升高可能是活动性系统性红斑狼疮的一种表现。
