Predictive value of microRNA-155-5p, microRNA-16 and microRNA-129-5p on the efficacy of continuous renal replacement therapy in children with septic shock / 中国医师进修杂志

ABSTRACT

Objective:To analyze the predictive value of miR-155-5p, miR-16 and miR-129-5p on the efficacy of continuous renal replacement therapy (CRRT) in children with septic shock.Methods:A total of 179 children with severe sepsis admitted to Shanxi Provincial Children′s Hospital from January 2021 to January 2022 were selected, 89 children with septic shock were selected as group A, 90 children with non-septic shock were selected as group B, and 80 healthy children were selected as group C. The expressions of miR-155-5p, miR-16 and miR-129-5p were measured and compared. The patients in the group A were divided into the effective group and the ineffective group according to the curative effect of CRRT treatment. The expressions of miR-155-5p, miR-16 and miR-129-5p in the two groups were compared, and its predictive value for the efficacy of CRRT treatment was analyzed.Results:Compared with group C and group B, the expressions of miR-155-5p in group A was higher: 2.56 ± 0.98 vs. 1.41 ± 0.35, 0.53 ± 0.11; and the expressions of miR-16 and miR-129-5p were lower: 1.00 ± 0.27 vs. 2.23 ± 0.98, 3.38 ± 1.01; 0.65 ± 0.17 vs.1.39 ± 0.22, 2.25 ± 0.76, there were statistical differences ( P<0.05). The results of Logistic regression analysis showed that the sequential organ failure assessment(SOFA) scores, white blood cell count, C reactive protein, procalcitonin, interleukin-6, tumor necrosis factor-alpha , N-terminal B-type natriuretic peptide precursor and the expressions of miR-155-5p, miR-16, miR-129-5p were independent risk factors for the efficacy of CRRT treatment in the children with septic shock. The results of Pearson correlation analysis showed that miR-155-5p was negative correlation with miR-16 and miR-129-5p ( r = - 0.411, - 0.369, P<0.05); and miR-16 was positive correlation with miR-129-5p ( r = 0.444, P<0.05). The results of receiver operating characteristic curve showed that the combination of the three items had a higher predictive value for the efficacy of CRRT in children with septic shock ( P<0.05). Children with high expression of miR-155-5p and low expression of miR-16 and miR-129-5p had higher mortality ( P<0.05). Conclusions:The expressions of miR-155-5p, miR-16 and miR-129-5p are abnormally in children with septic shock and are related to the efficacy of CRRT, which can be used for early prediction of the efficacy of CRRT.
