Methods: A total of 95 patients with SLE were divided into lupus nephritis group (LN group, n = 64) and non-lupus nephritis group (NLN group n=31) according to the diagnostic criteria of lupus nephritis, and another 35 healthy subjects were selected as normal control group. Blood samples were collected from all subjects before treatment. Serum CRP and serum uric acid concentrations were measured by ELISA. The levels of serum immunoglobulins were detected by immunoturbidimetry in the same time. Finally, the results were analyzed statistically. Results: The levels of serum CRP and serum uric acid in patients with SLE were significantly higher than those in control group. The levels of serum CRP and serum uric acid in LN group of SLE patients were significantly higher than those in NLN group and control group. Serum CRP level in NLN group was significantly higher than that in control group. Serum uric acid level in NLN group was slightly higher than that of the control group, but the difference was not statistically significant. The level of serum immunoglobulin in SLE patients was higher than that in control group. The levels of serum immunoglobulin IgG, IgA and IgM in LN group of SLE patients were significantly higher than those in NLN group and control group. The levels of serum immunoglobulin IgG, IgA and IgM in NLN group of SLE patients were all higher than those in control group. Conclusion: Humoral immune of SLE patients with renal injury was activated at different degree, B-cell hyperthyroidism, severe systemic inflammatory response and kidney damage at varying degrees. Serum CRP, serum uric acid and immunoglobulin (IgG, IgA and IgM) may be involved in SLE renal injury pathological process, which is the early diagnosis of reference indicators.展开更多
