Prospective Analysis of the Relationship Between the State of Periodontal Tissues and Changes in Selected Cardiovascular Parameters in Patients with Type 2 Diabetes.

BACKGROUND: Periodontitis is considered a risk factor in many systemic diseases, including cardiovascular pathologies and diabetes. Diabetes can also exacerbate early vascular changes, mainly due to the synthesis of advanced glycosylation end-products and oxidative stress. It has not yet been fully explained whether the additional presence of periodontal disease can affect the course of atherosclerosis and left ventricle hypertrophy in diabetic patients. OBJECTIVES: The aim of the study was to assess the relationship between periodontal and cardiovascular diseases and their progression in patients with type 2 diabetes. MATERIAL AND METHODS: The study included 119 patients diagnosed with type 2 diabetes. Periodontal pocket depth (PD), clinical attachment loss (CAL), plaque index (PI) and bleeding index (BOP) were determined. Basic laboratory tests were performed. The intima-media thickness (IMT) and the left ventricular mass index (LVMI) were determined by means of ultrasonography. After one year the examinations were repeated. The statistical analysis included the 84 patients who took part in both the first and second examinations. RESULTS: A positive correlation between the number of deep and active periodontal pockets and LVMI value was observed in men. The IMT value correlated with the mean CAL, PI and BOP, while a negative correlation was found between the IMT and the number of deep pockets, as well as between the IMT and the number of retained teeth. A multivariate analysis demonstrated a significant correlation between CAL and both IMT and LVMI change after one year. CONCLUSIONS: A relationship between periodontitis and cardiovascular diseases has been confirmed in diabetic patients. The most significant periodontal parameter in relation to the progression of atherosclerosis and left ventricle hypertrophy was shown to be clinical attachment loss - a measure of the history of periodontal disease during the patient's lifetime.

Intima-media thickness and other markers of atherosclerosis in patients with type 2 diabetes and periodontal disease.

BACKGROUND: Periodontal disease is an inflammatory process which results in increased cardiovascular risk in patients with type 2 diabetes mellitus (DM2). It is not clear, however, whether periodontal inflammation may be associated with increased markers of atherosclerosis in these patients. AIM: This cross-sectional study aimed to answer the question of whether periodontal disease in DM2 is associated with increased markers and risk factors of atherosclerosis. METHODS: One hundred and twenty one patients were included in the study. Sixteen were classified as periodontally healthy (BGI-H), 87 as having gingivitis (BGI-G), and 18 as having periodontitis with moderate bleeding (BGI-P2), according to the new Offenbacher classification. In all patients, intima-media thickness (IMT), pulse wave velocity (PWV), lipids, and C-reactive protein (CRP) were assessed. RESULTS: Patients with periodontitis and gingivitis had a higher IMT value compared to the BGI-H group (0.804 ± 0.112 and 0.772 ± 0.127 vs 0.691 ± 0.151 mm, p < 0.01 and p < 0.05, respectively, odds ratio 5.25 for having IMT ≥ 0.8 mm, 95% CI 1.1; 25). Patients from the BGI-P2 group also had higher blood pressure (BP) compared to the BGI-G and BGI-H groups, and higher CRP compared to the BGI-G group (4.6 ± 2.3 vs 3.8 ± 4.8 mg/L, p < 0.01). Lipid parameters and PWV were comparable in all the groups. CONCLUSIONS: Periodontal inflammation in patients with DM2 seems to be associated with increased IMT and BP, but not with greater arterial stiffness. These results support the hypothesis that periodontal disease may be associated with a vascular pathology.

Blood pressure and left ventricular mass in subjects with type 2 diabetes and gingivitis or chronic periodontitis.

INTRODUCTION: This study aimed to answer the question of whether chronic periodontitis in subjects with type 2 diabetes mellitus is associated with increased left ventricular mass (LVM) and systemic and central blood pressure (CBP). MATERIAL AND METHODS: One hundred and fifty-five subjects with type 2 diabetes (67 F, 88 M, mean age 61.1±6.9 years, BMI 32.7±5.7 kg/m(2)) were divided according to their periodontal status into biofilm-gingival interface - healthy (BGI-H, 14 subjects), BGI-gingivitis (BGI-G, 119 subjects) and BGI-periodontitis (BGI-P, 22 subjects) groups. In all subjects, LVM, systemic and CBP were measured. The LVM index (LVMI) was calculated. RESULTS: (1) BGI-P and BGI-G subjects, respectively, had higher (mean; 95% CI) LVM (238.6 g; 206.6-267.4 and 222.8 g; 207.0-238.2) versus BGI-H subjects (170.3 g; 125.5-217.8).(2) BGI-P and BGI-G subjects, respectively, had higher (mean; 95% CI) LVM1 (95.2 g/m(2) ; 82.9-107.4) and 87.8 g/m(2) ; 81.5-94.1) versus BGI-H subjects (63.7 g/m(2) ; 45.2-62.3).(3) BGI-P subjects had higher central and systemic systolic and diastolic blood pressure than subjects from BGI-G and BGI-H groups. CONCLUSION: In subjects with type 2 diabetes, periodontitis and gingivitis are associated with increased LVM and periodontitis is associated with increased central and systemic blood pressure.
