[Matrix metalloproteinase-3 in patients with systemic lupus erythematosus and its significance in differentiating disease activity from pulmonary infections]
Abstract
The purpose of this study is to investigate the matrix metalloproteinase-3 (MMP-3) levels in patients with systemic lupus erythematosus (SLE) and its significance in identifying disease activity and pulmonary infections. A total of 122 SLE patients were enrolled, including 21 with pulmonary infections, 16 with arthritis, 26 with nephritis, 10 with vasculitis, and 23 healthy controls. Serum MMP-3, C-reactive protein (CRP), serum amyloid A (SAA), and haptoglobin (HPT) levels were measured in all subjects. The results showed that the levels of MMP-3 in SLE combined with pulmonary infections [(230.10±44.92) μg/L], arthritis [(140.20±20.76) μg/L], nephritis [(155.40±23.36) μg/L] were higher than those in SLE only [(91.74±10.47) μg/L]. The levels of MMP-3 [(210.30±45.71) μg/L], CRP [(12.11±5.21) mg/L], HPT [(1.57±0.23) g/L] in active SLE combined with pulmonary infections were higher than those inactive SLE without pulmonary infections including MMP-3 [(124.00±15.22) μg/L], CRP [(7.76±2.96) mg/L], HPT [(0.89±0.09) g/L]. The levels of CRP [(10.03±2.70) mg/L], SAA [(89.22±36.77) mg/L] in active SLE with pulmonary infections and CRP[(7.76±2.96) mg/L], SAA [(60.22±19.7) mg/L] in active SLE without pulmonary infections were higher than CRP [(1.90±0.39) mg/L], SAA [(17.60±3.89) mg/L] in stable SLE with pulmonary infections. It suggests that the levels of CRP and SAA are elevated in active SLE with pulmonary infections. Serum MMP-3 in combination with CRP may assist in differentiating from SLE pulmonary infections.
探讨系统性红斑狼疮（SLE）患者血清基质金属蛋白酶-3（MMP-3）水平及其在鉴别疾病活动与合并肺部感染中的意义。入选住院SLE患者122例，其中SLE合并肺部感染者21例，合并关节炎者16例，合并肾炎者26例，合并血管炎者10例；另选健康对照者23例。检测所有受试者血清MMP-3、C反应蛋白（CRP）、血清淀粉样蛋白A（SAA）、触珠蛋白（HPT）水平。结果显示，SLE合并肺部感染者[（230.10±44.92）μg/L]、关节炎者[（140.20±20.76）μg/L]、肾炎者[（155.40±23.36）μg/L]血清MMP-3水平高于单纯SLE者[（91.74±10.47）μg/L]。SLE合并肺部感染者血清MMP-3、CRP[（1.99±1.03）mg/L]、SAA[（92.19±23.93）mg/L]、HPT[（1.42±0.18）g/L]水平高于SLE无肺部感染者[MMP-3为（115.40±8.93）μg/L；CRP为（0.44±0.13）mg/L；SAA为（38.79±8.98）mg/L；HPT为（0.88±0.06）g/L]。SLE活动合并肺部感染者血清MMP-3[（210.30±45.71）μg/L]、CRP[（12.11±5.21）mg/L]、HPT[（1.57±0.23）g/L]水平高于SLE活动无肺部感染者[MMP-3为（124.00±15.22）μg/L；CRP为（7.76±2.96）mg/L；HPT为（0.89±0.09）g/L]，SLE稳定合并肺部感染者血清CRP[（10.03±2.70）mg/L]、SAA[（89.22±36.77）mg/L]水平、SLE活动无肺部感染者血清CRP[（7.76±2.96）mg/L]、SAA[（60.22±19.7）mg/L]水平均高于SLE稳定无肺部感染者[CRP为（1.90±0.39）mg/L；SAA为（17.60±3.89）mg/L]。提示SLE疾病活动与合并肺部感染时血清CRP、SAA水平升高，血清MMP-3水平在SLE合并肺部感染时升高，因此血清MMP-3联合CRP可能协助鉴别SLE疾病活动与合并肺部感染。.
