Serum C-reactive protein levels and lipid profiles concentrations in moderate to severe periodontitis and coronary heart disease: a comparative study / 中华口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the correlation between moderate to severe periodontitis and coronary heart disease (CHD) and to examine the serum C-reactive protein (CRP) levels in subjects with CHD and/or moderate to severe periodontitis.</p><p><b>METHODS</b>Serum CRP levels, serum lipids [low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), total cholesterol (TC) and triglyceride (TG)] and clinical periodontal parameters [clinical attachment loss (CAL), probing depth (PD), and bleeding on probing (BOP)] were measured and analyzed in coexistent moderate to severe periodontitis and CHD patients (n = 47), CHD patients (n = 28), moderate to severe periodontitis patients (n = 40), and healthy subjects (n = 40).</p><p><b>RESULTS</b>The serum CRP levels in control group, moderate to severe periodontitis patients, CHD patients and patients with both diseases were (1.30 +/- 0.15), (2.44 +/- 0.18), (5.99 +/- 0.82) and (6.88 +/- 0.71) mg/L, respectively. The differences among these four groups were significant (P < 0.001). The multivariate logistic regression revealed that moderate to severe periodontitis patients exhibited markedly elevated odds of having CHD (OR = 2.417, 95% CI 1.126 - 6.659). The total cholesterol levels were also significantly different among the four groups (P = 0.017).</p><p><b>CONCLUSIONS</b>The moderate to severe periodontitis was associated with elevated serum CRP levels which may in turn affect the initiation and progression of CHD, and may be a risk factor for CHD.</p>
