AbstractObjective: To investigate clinical immunological characteristics and imaging findings of multiple organ damage of systemic lupus erythematosus (SLE) patients with hematologic involvement. Methods: SLE patients diagnosed in the Second Affiliated Hospital of Nanchang University from June 2015 to March 2019 were selected, including 93 SLE patients with hematologic involvement and 68 SLE patients without hematologic involvement. Immunological indicators such as autoantibodies, immunoglobulin G (IgG), complement 4 (C4) and imaging data of several organs were measured respectively. The results were statistically analyzed. Results: SLE patients with hematologic involvement were more likely to have autoimmune hemolytic anemia (AIHA) (20.43%, P<0.05). The erythrocyte sedimentation rate (ESR) of SLE patients with hematologic involvement was 75.82 (±35.33) mm/h, IgG was 28.84 (±6.00) g/L and C4 was 0.073 (±0.031) g/L (P< 0.05). The area under the curve (AUC) of IgG was the highest among the above indicators (P<0.01). The positive anti-RO-52 antibody (OR=15.926, P<0.05) was an independent risk factor for pulmonary inflammatory lesions in SLE patients with hematologic involvement. Conclusion: Compared with the control group, abnormal immunological indicators and multiple organs damage are more obvious. Positive anti-RO-52 antibody may play an important role in the pathogenesis of pulmonary inflammation in SLE patients.© The author(s).
