Periodontitis May Deteriorate Sinus of Valsalva Dilatation in Marfan Syndrome Patients

抄録

Marfan syndrome (MFS) is a systemic connective tissue disorder that is caused by mutations of fibrillin-1. While MFS patients are at a high risk of periodontitis and aortic diseases, little causal information has been provided to date. To clarify the relationship, their oral condition and sinus of Valsalva (SoV) were evaluated.
The subjects were patients with MFS (n = 33) who attended the University of Tokyo Hospital. We divided them into two groups; MFS patients with highly dilated (the diameters were equal to or more than 39 mm) SoV (high group, n = 18) and MFS patients with mildly dilated (less than 39 mm) SoV (mild group, n = 15). Blood examinations, echocardiograms, and full-mouth clinical measurements, including number of teeth, probing pocket depth (PPD), bleeding on probing (BOP), and community periodontal index (CPI) were performed.
We found that the high group patients had greater rates of BOP compared to that of the mild group. Furthermore, the high group tended to have higher serum levels of C-reactive protein, matrix metalloproteinase-9, and transforming growth factor-β compared to the mild group.
