Correlation between soluble vascular endothelial growth factor receptor-1 (sVEGFR-1) concentration, VEGFR1 gene polymorphisms and systemic lupus erythematosus (SLE) risk remains unclear. The present case-control study comprised 254 SLE patients, 385 other rheumatic diseases patients and 390 healthy controls. Serum levels of sVEGFR-1 were detected by enzyme-linked immunosorbent assay. Seven VEGFR1 genetic variants (rs2296188, rs9943922, rs2296283, rs7324510, rs9554322, rs9582036, rs9554320) were genotyped by KASP. Serum levels of sVEGFR-1 were up-regulated in SLE and positively correlated with disease activity. Furthermore, serum sVEGFR-1 presented a distinctive elevation in SLE in comparison with other rheumatic diseases. Frequencies of allele T of rs2296283 and allele G of rs9554322 were significant lower in SLE patients (P = 0.003, P = 0.004). Frequencies of genotypes TT of rs2296188 and rs2296283 were declined in patients compared with healthy controls (P = 0.039, P = 0.033). CC genotype of rs7324510 and rs9582036 was negatively correlated with SLE risk (OR = 0.538, OR = 0.508). Distribution of GG, GC, GG + GC genotypes of rs9554322 were different between SLE patients and healthy controls (P = 0.027, P = 0.036, P = 0.010). Moreover, frequency of TC genotype of rs7324510 was higher in SLE patients with lupus headache (χ = 9.924, P = 0.039) and frequency of TC genotype of rs9943922 was lower in patients with cylindruriain (χ = 7.589, P = 0.026). Frequencies of allele C of rs7324510 and allele T of rs9943922 were decreased in SLE patients with cylindruria and hypocomplementemia, respectively (χ = 4.195, P = 0.041, χ = 3.971, P = 0.046). However, frequency of allele C of rs9554322 was increased in SLE patients with pyuria (χ = 11.702, P = 0.001). In addition, SLE patients carrying GG, GC, CC genotypes for rs9554322 had higher levels of serum sVEGFR-1. In conclusion, serum sVEGFR-1 was elevated in SLE patients and may be a disease marker. VEGFR1 gene polymorphisms related to risk of SLE in a Chinese Han population.
可溶性血管内皮生长因子受体-1(sVEGFR-1)浓度、VEGFR1 基因多态性与系统性红斑狼疮(SLE)风险之间的相关性尚不清楚。本病例对照研究包括 254 例 SLE 患者、385 例其他风湿性疾病患者和 390 例健康对照。采用酶联免疫吸附试验检测血清 sVEGFR-1 水平。采用 KASP 法对 7 个 VEGFR1 基因变异(rs2296188、rs9943922、rs2296283、rs7324510、rs9554322、rs9582036、rs9554320)进行基因分型。SLE 患者血清 sVEGFR-1 水平升高,与疾病活动度呈正相关。此外,与其他风湿性疾病相比,SLE 患者血清 sVEGFR-1 水平明显升高。SLE 患者 rs2296283 等位基因 T 和 rs9554322 等位基因 G 的频率显著降低(P=0.003,P=0.004)。与健康对照组相比,SLE 患者 rs2296188 和 rs2296283 的 TT 基因型频率降低(P=0.039,P=0.033)。rs7324510 的 CC 基因型和 rs9582036 的 CC 基因型与 SLE 风险呈负相关(OR=0.538,OR=0.508)。rs9554322 的 GG、GC、GG+GC 基因型在 SLE 患者和健康对照组之间的分布不同(P=0.027,P=0.036,P=0.010)。此外,SLE 伴狼疮头痛患者 rs7324510 的 TC 基因型频率较高(χ²=9.924,P=0.039),SLE 伴狼疮性肾炎患者 rs9943922 的 TC 基因型频率较低(χ²=7.589,P=0.026)。SLE 伴狼疮性肾炎和低补体血症患者 rs7324510 的 C 等位基因和 rs9943922 的 T 等位基因频率降低(χ²=4.195,P=0.041,χ²=3.971,P=0.046)。然而,SLE 伴菌尿患者 rs9554322 的 C 等位基因频率升高(χ²=11.702,P=0.001)。此外,携带 rs9554322 的 GG、GC、CC 基因型的 SLE 患者血清 sVEGFR-1 水平较高。综上所述,SLE 患者血清 sVEGFR-1 水平升高,可能是一种疾病标志物。VEGFR1 基因多态性与中国汉族人群的 SLE 发病风险相关。
