Abstract

Objectives

The aim of this study was to examine the association between periodontal disease and renal function in elderly women with different genotypes.

Material and Methods

A total of 332 postmenopausal never-smoking women were analysed. Poor renal function was defined as serum cystatin C > 0.91 mg/l. Periodontal disease markers such as periodontal inflamed surface area (PISA) were evaluated. Selected variables, including PISA quartile, body mass index (BMI), HbA1C and age in Arg allele carriers and non-carriers based on the beta-3 adrenergic receptor, or between Ala allele carriers and non-carriers based on peroxisome proliferator-activated receptor gamma, were analysed using multiple logistic regression analysis.

Results

The odds ratios of serum cystatin C level and PISA (fourth quartile) were significantly positive for both Arg (2.52; = 0.035) and Ala allele non-carriers (2.36; = 0.021). A significant association was also found between serum cystatin C level and BMI for both Arg (1.18; = 0.001) and Ala allele non-carriers (1.12; = 0.003).

Conclusion

The results of this study suggest that periodontal inflammation might be associated with renal function. Furthermore, in both the Arg and Ala allele non-carriers, the associations between BMI and PISA for renal function became stronger.
