Abstract
OBJECTIVE: To investigate the relationship between serum C1q tumor necrosis factor-related protein 9 (CTRP9) level and the risk of diabetic retinopathy (DR) in patients with type 2 diabetes mellitus (T2DM). OBJECTIVE: A total of 291 patients with T2DM underwent fundus examination, and their serum levels of CTRP9, insulin and adiponectin were measured using enzyme- linked immunosorbent assay. According to results of fundus examination, the patients were divided into DR group and non-DR (NDR) group, and logistic regression was used to analyze the relationship between serum CTRP9 levels and DR in T2DM patients. OBJECTIVE: Compared with those in NDR group, the patients with DR showed significantly increased serum CTRP9 level (P < 0.001) and decreased serum adiponectin level (P < 0.001). Pearson correlation analysis showed that in patients with T2DM complicated by DR, serum CTRP9 levels had a significant positive correlation with DR stage (P < 0.05) and a negative correlation with serum adiponectin level (P < 0.001). Multivariate logistic regression analysis showed that with the increase of serum CTRP9 level, the risk of DR is significantly increased in patients with T2DM. OBJECTIVE: In patients with T2DM complicated by DR, an increased serum CTRP9 level suggests a compensatory response to DR.
