Abstract:

Objective To explore the effects of serum apolipoprotein B/apolipoprotein A-1 (ApoB/ApoA-1) and urinary microalbumin (mAlb) on the severity of diabetic macular edema (DME). Methods From June 2022 to May 2023, 228 DME patients admitted to the Cangzhou Eye Hospital were selected as the research subjects. According to the severity of DME, patients were divided into the mild group, the moderate group and the severe group. The ApoB/ApoA-1 ratio and mAlb level of the three groups of patients were compared. The correlation between the degree of DME and the levels of ApoB/ApoA-1 ratio and mAlb was analyzed using the Spearman method. Univariate analysis and multivariate Logistic regression analysis were used to detect risk factors for developing severe DME. The diagnostic value of the ApoB/ApoA-1 ratio and mAlb for severe DME was analyzed using the receiver operating characteristic (ROC) curve. Results The levels of ApoB/ApoA-1 and mAlb in the mild, moderate and severe groups increased successively (P<0.05). The Spearman correlation analysis showed that the severity of DME was positively correlated with the levels of ApoB/ApoA-1 and mAlb (rs were 0.502 and 0.836 respectively, both P<0.01). Compared with the mild-moderate group, the severe group had a longer duration of diabetes and insulin treatment time, and higher ApoB/ApoA-1 ratio, mAlb and HbA1c levels (P<0.05). The multivariate Logistic regression model showed that higher levels of ApoB/ApoA-1, mAlb, HbA1c and longer duration of diabetes were all risk factors for developing severe DME (P<0.05). The ROC curve analysis results showed that the area under the curve (AUC) for the ApoB/ApoA-1 ratio and the mAlb level alone and in combination in evaluating the risk of developing severe DME was 0.711, 0.782 and 0.927 respectively. The DeLong test indicated that the diagnostic efficacy of the combined model was significantly better than that of the single indicator (Z values were 5.063 and 4.099 respectively, both P<0.05). Conclusion The ApoB/ApoA-1 ratio and mAlb level in DME patients are closely related to the severity of the disease, and they are also risk factors for developing severe DME. The combined detection of these two indicators has important clinical reference value for identifying high-risk individuals with progressive disease and warning of the risk of severe DME occurrence.
