Abstract:

Objective To investigate the incidence of malnutrition-inflammation complex syndrome (MICS) in patients with end-stage renal disease receiving maintenance hemodialysis (MHD) and to analyze its associated risk factors, thereby providing a theoretical basis for the clinical prevention and treatment of MICS. Methods A retrospective analysis was performed on the clinical data of 108 patients who received end-stage MHD at Huanghe S&T College Affiliated Hospital and Henan Provincial People's Hospital from July 2022 to July 2025. According to the occurrence of MICS, the patients were divided into a MICS group and a non-MICS group. General data, dialysis-related data, and laboratory indicators were collected from both groups. Differences between the two groups were compared by univariate analysis, and independent risk factors were identified using a multivariate logistic regression model. Results Among the 108 patients receiving end-stage MHD, 74 were in the MICS group (68.5%) and 34 in the non-MICS group (31.5%). In terms of baseline characteristics, the MICS group was older and had a higher prevalence of diabetes mellitus than the non-MICS group (P<0.05). Regarding dialysis-related indicators, dialysis vintage was longer in the MICS group than in the non-MICS group (P<0.05). For laboratory indicators, the MICS group had lower albumin (Alb) and hemoglobin levels, but higher high-sensitivity C-reactive protein (hs-CRP) and interleukin-6 levels than the non-MICS group (P<0.05). With the occurrence of MICS after end-stage MHD as the dependent variable (no=0, yes=1), variables with statistically significant differences in univariate analysis were assigned and included as independent variables in the model. Multivariate logistic regression showed that age ≥65 years, dialysis vintage ≥3 years, Alb <35 g/L, and hs-CRP ≥10 mg/L were independent risk factors for MICS in patients receiving end-stage MHD (P<0.05). Based on the multivariate logistic regression output, a prediction model for MICS in end-stage MHD was established: Y=0.659×age+0.435×dialysis vintage+0.578×Alb+0.701×hs-CRP-6.583. Receiver operating characteristic (ROC) curve analysis showed that the area under the curve (AUC) of this model for predicting MICS in end-stage MHD was 0.878, with a specificity of 86.50% and a sensitivity of 75.69%. Conclusion The incidence of MICS in patients receiving end-stage MHD is high, reaching 68.52%. Advanced age, prolonged dialysis duration, low serum Alb, and elevated inflammatory markers are independent risk factors. The prediction model constructed on this basis demonstrates good predictive performance.
