Insulin-like growth factor-binding proteins (IGFBPs) and connective tissue growth factor (CTGF) participate in angiogenesis. Dermatomyositis (DM) is characterized by microvasculopathy-derived skin lesions. Here, we investigated the clinical significance of serum IGFBP and CTGF levels in DM patients.
In this study, 65 DM patients and 30 healthy controls were enrolled. Serum IGFBP and CTGF levels were examined by ELISA, and their correlation with clinical and laboratory findings was analyzed by Spearman's correlation.
Serum IGFBP-2, IGFBP-4, and CTGF levels were higher in DM patients than in healthy controls (median (quartile): 258.9 (176.4-326.1) ng/mL vs. 167.7 (116.1-209.4) ng/mL, < 0.0001; 450.4 (327.3-631.8) ng/mL vs. 392.2 (339.0-480.2) ng/mL, = 0.04; and 45.71 (38.54-57.45) ng/mL vs. 35.52 (30.23-41.52) ng/mL, = 0.001, respectively). IGFBP-2 and CTGF levels were positively correlated with cutaneous ( = 0.257, = 0.040 and = 0.427, = 0.015, respectively) and global ( = 0.380, = 0.002 and = 0.292, = 0.019, respectively) disease activity in DM patients.
Serum IGFBP-2 and CTGF levels were increased in patients with DM and correlated with cutaneous and global disease activity.
胰岛素样生长因子结合蛋白(IGFBPs)和结缔组织生长因子(CTGF)参与血管生成。皮肌炎(DM)的特征是微血管病源性皮肤损伤。在此,我们研究了 DM 患者血清 IGFBP 和 CTGF 水平的临床意义。
本研究纳入了 65 例 DM 患者和 30 例健康对照者。采用 ELISA 检测血清 IGFBP 和 CTGF 水平,并采用 Spearman 相关分析分析其与临床和实验室发现的相关性。
DM 患者的血清 IGFBP-2、IGFBP-4 和 CTGF 水平高于健康对照组(中位数(四分位数):258.9(176.4-326.1)ng/mL 比 167.7(116.1-209.4)ng/mL, <0.0001;450.4(327.3-631.8)ng/mL 比 392.2(339.0-480.2)ng/mL, = 0.04;和 45.71(38.54-57.45)ng/mL 比 35.52(30.23-41.52)ng/mL, = 0.001)。IGFBP-2 和 CTGF 水平与皮肤( = 0.257, = 0.040 和 = 0.427, = 0.015,分别)和整体( = 0.380, = 0.002 和 = 0.292, = 0.019,分别)疾病活动在 DM 患者中呈正相关。
DM 患者的血清 IGFBP-2 和 CTGF 水平升高,并与皮肤和整体疾病活动相关。
