- This study investigated the effect of mechanical infection control for periodontitis and periodontal surgery on the prevalence of well-established risk factors for atherosclerosis, and plasma levels of cytokines, antibodies against heat shock proteins and markers of systemic inflammation. Sixty-eight patients between 39 and 73 years of age with severe periodontitis who had been referred to four specialist periodontology clinics in Sweden were investigated. A fasting venous blood sample was taken at baseline and additional samples were collected after 3 and 12 months. A total of 54 patients underwent periodontal treatment. The periodontal treatment was successful, as pathogenic gingival pockets decreased significantly. Plasma glucose, lipids and markers of systemic inflammation were not significantly altered after 3 months. One year after the initial treatment, HDL-C concentrations were significantly increased (Δ0.08 mmol/L) whereas LDL-C concentrations decreased (Δ0.23 mmol/L). Haptoglobin concentrations were also lower. Interleukin-18 and interferon-γ levels were also lower after 12 months (60 ng/L (-23%) and 11 ng/L (-97%) respectively). Treatment had no effect on plasma levels of IgA, IgG1, IgG2 antibodies against heat shock proteins. In conclusion, this study indicates that standard treatment for periodontal disease induces systemic changes in several biochemical markers that reflect the risk for atherosclerosis.

- Background and aimsMicroRNA (miR) are important regulators of gene expression and biological processes and have recently been suggested as possible biomarkers for abdominal aortic aneurysm (AAA) disease. The aim of the present study was to assess the role of miR as biomarkers for initiation and progression of AAA disease, through evaluation of a wide range of miRs in a large population-based cohort, with AAA patients with linked clinical data regarding risk factors, AAA size and growth, as well as controls.MethodsThe expression of the 172 most commonly expressed miRs in plasma was analyzed by real-time PCR in samples from 169 screening-detected AAA patients and 48 age-matched controls.ResultsFor 103 miRs, there was a significant difference in expression between AAA and controls. Of these, 20 miRs were differently expressed between fast and slow growing aneurysms. These miRs target genes known to be involved in AAA disease as well as novel genes and pathways. By combining the top altered miRs together with clinical variables, strong predictive values, determining growth of AAA, were obtained (area under curve = 0.86, p < 0.001).ConclusionsThis large cohort study identified several novel miRs with altered expression in AAA patients when compared to controls. Assessment of miR expression may offer an opportunity to predict disease progression and aneurysm growth.
