RESUMEN

Objective:To investigate the urineinterleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-33 (IL-33) and matrix metalloproteinase-9 (MMP-9) in patients with IgA nephropathy (IgAN) and their predictive value for disease progression.Methods:110 IgAN patients admitted to Zhuozhou Hospital from January 2018 to October 2021 were selected and divided into IgAN progression group (39 cases) and IgAN non progression group (71 cases) according to the progress of IgAN patients. According to the Oxford Classification Standard System (MEST-C) of IgAN, they were divided into MEST-C≥3 group (42 cases) and MEST-C<3 group (68 cases). According to the estimated glomerular filtration rate (eGFR), they were divided into eGFR≥50 ml/(min·1.73 m 2) group (group A, 63 cases) and eGFR<50 ml/(min·1.73 m 2) group (group B, 47 cases). According to the amount of urinary protein, they were divided into urinary protein≥1.5 g/24 h group (66 cases) and urinary protein<1.5 g/24 h group (44 cases). Multivariate logistic regression was used to analyze the risk factors affecting the progression of IgAN. Receiver operating characteristic (ROC) curve was drawn to analyze the value of urinary IL-6, IL-8, IL-33 and MMP-9 levels in predicting the progression of IgAN. Results:The urinary IL-6, IL-8, IL-33 and MMP-9 levels in IgAN progression group were significantly higher than those in IgAN non progression group, while the serum albumin, eGFR and complement C3 in the IgAN progression group were lower than those in the IgAN non progression group (all P<0.05). The urinary IL-6, IL-8, IL-33 and MMP-9 levels in the MEST-C≥3 group were significantly higher than those in the MEST-C<3 group (all P<0.001). The urinary IL-6, IL-8, IL-33 and MMP-9 levels in the eGFR<50 ml/(min·1.73 m 2) group were significantly higher than those in the eGFR≥50 ml/(min·1.73 m 2) group (all P<0.001). The urinary IL-6, IL-8, IL-33 and MMP-9 in the urinary protein≥1.5 g/24 h group were significantly higher than those in the urinary protein<1.5 g/24 h group (all P<0.001). Multivariate logistic regression analysis showed that the course of disease, serum albumin, eGFR, urinary protein, IL-6, IL-8, IL-33 and MMP-9 were risk factors affecting the progression of IgAN (all P<0.005). The ROC curve showed that the area under the curve (AUC) of IL-6, IL-8, IL-33 and MMP-9 in predicting the progression of IgAN was 0.956 (95% CI: 0.891-0.998), and the sensitivity and specificity were 98.4% and 86.2%, respectively. Conclusions:The elevated levels of urinary IL-6, IL-8, IL-33 and MMP-9 are closely related to the progress of IgAN, and the combination of these four indicators has a good value in predicting the progress of IgAN.
