Malnutrition- inflammation- atherosclerosis (MIA) syndrome associates with periodontitis in end-stage renal disease patients undergoing hemodialysis: a cross-sectional study

August 3, 2023

Summary

Malnutrition-inflammation-atherosclerosis (MIA) syndrome is a significant risk factor for mortality in patients undergoing hemodialysis. This study aimed to investigate the association between MIA syndrome and oral health status in hemodialysis patients. A cross-sectional study was conducted on 254 hemodialysis patients. Comprehensive medical and dental examinations were performed. Three components were included to define MIA syndrome: Geriatric Nutritional Risk Index, serum high-sensitivity C-reactive protein, and history of cardiovascular events as indicators of malnutrition, inflammation, and atherosclerosis, respectively. The association of MIA syndrome components with periodontitis and occlusal support was examined by multiple-ordered logistic regression analysis. Of 254 participants, 188 (74.0%) had at least one component of MIA syndrome. After adjusting for possible confounding factors, severe periodontitis was significantly associated with presence of more components of MIA syndrome (odds ratio [OR]: 2.64, 95% confidence interval [CI], 1.44–4.84, p = 0.002) and inflammation and malnutrition components (OR: 2.47 and 3.46, 95% CI 1.16–5.28 and 1.70–7.05, p = 0.020 and 0.001). On the other hand, occlusal support, evaluated by Eichner index, was not significantly associated with MIA syndrome or any of its components. In conclusion, periodontitis is associated with MIA syndrome, particularly with inflammation and malnutrition in hemodialysis patients, independent of occlusal support.
