Abstract:
OBJECTIVE:To investigate the clinical and immunological characteristics of systemic lupus erythematosus (SLE) with retinopathy.
METHODS:Fifty SLE patients with retinopathy without hypertension and diabetes (retinopathy group) who were hospitalized in the Peking University People's Hospital from January 2009 to July 2022 were screened. Fifty SLE patients without blurred vision during the course of the SLE and without retinopathy in the fundus examinations (non-retinopathy group) matched for sex and age were selected. Their clinical manifestations, laboratory tests and lymphocyte subsets were statistically analyzed.
RESULTS:The most common fundus ocular change of the SLE patients with retinopathy was cotton-wool spots (33/50, 66.0%), followed by intraretinal hemorrhage (31/50, 62.0%). Retinopathy could occur at any stage of SLE duration, with a median of 1 year (20 days to 30 years). The proportion of lupus nephritis (72.0% vs. 46.0%, P=0.008) and serositis (58.0% vs. 28.0%, P=0.002) in the retinopathy group were significantly higher than those in the non-retinopathy group. The proportion of neuropsychiatric systemic lupus erythematosus (NPSLE) in the retinopathy group was higher, but there was no significant difference between the two groups. Compared with the non-retinopathy group, the proportion of positive anti-cardiolipin antibody (30.0% vs. 12.0%, P=0.027), the SLEDAI score (median 22.0 vs. 10.5, P < 0.001), erythrocyte sedimentation rate (P < 0.001), C-reactive protein (P=0.019) and twenty-four hours urine total protein level (P=0.026) in the retinopathy group were significantly higher, and the hemoglobin level was significantly lower [(91.64±25.18) g/L vs. (113.96±18.57) g/L, P < 0.001]. The proportion of CD19+ B cells in peripheral blood of the patients with SLE retinopathy was significantly increased (P=0.010), the proportion of CD4+ T cells was significantly decreased (P=0.025) and the proportion of natural killer (NK) cells was lower (P=0.051) when compared with the non-retinopathy group.
CONCLUSION:Retinopathy in SLE suggests a higher activity of SLE disease with more frequent hematologic and retinal involvement. It is recommended to perform fundus examination as soon as a patient is diagnosed with SLE. SLE patients with retinopathy may have stronger abnormal proliferation of B cells, and aggressive treatment should be applied to prevent other important organs involvement.
