Abstract

Background: Primary nephrotic syndrome (NS) is a common disease of the urinary system with an unclear pathogenesis. We aimed to detect the levels of urinary exosomal miR-23b-3p, miR-30a-5p, and miR-151-3p in children with primary NS, and to explore their diagnostic value for NS.

Methods: A total of 115 patients with NS who were admitted to the hospital from June 2017 to June 2019 were selected as the observation group. According to the disease progression, they were divided into an active group (acute active phase, n=68) and remission group (remission phase, n=47). In all, 50 healthy children were selected as the control group. Levels of urinary exosomal miR-23b-3p, miR-30a-5p, and miR-151-3p of each group in different periods were detected.

Results: The 24-h urine protein, serum albumin (ALB), and serum total cholesterol (TC) levels were significantly higher in the observation group than in the control group (P<0.05), while those in the active group were significantly higher than those in the remission group (P<0.05). The levels of miR-23b-3p and miR-30a-5p were significantly higher in the observation group than in the control group, and significantly higher in the active group than in the remission group (P<0.05). No miR-151-3p was detected in the urinary exosomes of the two groups. After treatment, levels of exosomal miR-23b-3p and miR-30a-5p in the two groups both decreased significantly (P<0.05). Results of receiver operating curve (ROC) curve analysis showed that urinary exosomal miR-23b-3p and miR-30a-5p can be used to identify children with NS and healthy children. The area under the ROC curve (AUC) was 0.711 for miR-23b-3p and 0.844 for miR-30a-5p.

Conclusions: The levels of miR-23b-3p and miR-30a-5p in urinary exosomes of children with NS were significantly higher than those in healthy children, and decreased significantly after treatment, indicating that miR-23b-3p and miR-30a-5p in urinary exosomes are potential indicators for diagnosing the progression of NS and monitoring the treatment effect.
