Abstract:
Objective:To investigate the expression and clinical significance of serum miR-193-5p and miR-196-5p in children with IgA nephropathy (IgAN).Methods:The 95 children with IgAN (IgAN group), 80 children with non IgAN nephritis (non IgAN group) and 50 normal subjects (control group) in Sanya Women and Children's Hospital of Shanghai Children's Medical Center and Sanya People's Hospital were selected to be included in this study. According to Oxford classification score (MEST), children with IgAN were divided into 35 cases with MEST≥3 points and 60 cases with MEST<3 points. The serum levels of miR-193-5p, miR-196-5p, IgA/C3 and galactose deficient IgA1 molecule (Gd-IgA1) in each group were compared. The receiver operating characteristic (ROC) curve was drawn to analyze the value of miR-193-5p, miR-196-5p, IgA/C3 and Gd-IgA1 in the diagnosis of IgAN. Pearson correlation analysis was used to analyze the correlation between the expression levels of miR-193-5p, miR-196-5p and IgA/C3 and Gd-IgA1.Results:The serum levels of miR-193-5p, miR-196-5p, IgA/C3 and Gd-IgA1 in IgAN group were significantly higher than those in non IgAN group and control group (all P<0.001). The levels of miR-193-5p, miR-196-5p, IgA/C3 and Gd-IgA1 in MEST≥3 group were significantly higher than those in MEST<3 group (all P<0.001). ROC curve analysis showed that the area under the curve for the combined diagnosis of IgAN by miR-193-5p, miR-196-5p, IgA/C3 and Gd-IgA1 was 0.958 (95% CI: 0.902-0.998), with sensitivity of 98.6% and specificity of 86.4%. Pearson correlation analysis showed that the expression levels of serum miR-193-5p and miR-196-5p in IgAN children were positively correlated with IgA/C3 and Gd-IgA1 (all P<0.001). Conclusions:The expression levels of serum miR-193-5p and miR-196-5p were significantly increased in children with IgAN, and the combined detection of IgA/C3 and Gd-IgA1 has high value for the diagnosis of IgAN in children.
