简要总结
This study investigates the differences between subjects with and without periodontitis in: the prevalence of (pre)diabetes mellitus, the risk of atherosclerotic cardiovascular disease, the prevalence of metabolic syndrome and the risk of obstructive sleep apnea syndrome.
详细描述
Diabetes Mellitus (DM), Atherosclerotic Cardiovascular Disease (ASCVD), Metabolic Syndrome (MetS) and Obstructive Sleep Apnea Syndrome (OSAS) are major health problems. However due to absence of symptoms and/or lack of knowledge, people are often unaware of having DM, ASCVD, MetS or OSAS while early treatment could prevent or stop the progression of these diseases. Therefore risk indicators for early detection of DM, ASCVD, MetS and OSAS are needed and proposed.
Many studies demonstrate the association between oral diseases and DM and/or ASCVD. The most observed chronic oral disease is periodontitis. Periodontitis is a common chronic multifactorial inflammatory disease of the supporting structures of the teeth. DM and ASCVD might, due to their proinflammatory state and alteration of the immune system, contribute to the onset and/or progression of periodontitis. Therefore periodontitis could be considered as an early sign of an underlying vascular and/or metabolic pathology.
Some studies have also reported a positive association between periodontitis and MetS. The MetS prevalence in patients with periodontitis was shown to be higher than controls and MetS showed to be associated with severe periodontitis. The association between periodontitis and OSAS is less established, however there is some evidence to a plausible association between periodontal disease and Obstructive Sleep Apnea (OSA).
Due to the broad overlap of objective biomarkers, in this study, subjects with or without periodontitis will be screened for determining the prevalence of (pre)DM, the 10 year risk of ASCVD, the prevalence of MetS and the risk of OSAS.
The screening will be based on clinical measures, specific blood markers determined by a developed finger stick procedure and three questionnaires.

结局指标
主要结局
Prevalence of prediabetes and diabetes (DM)
时间窗: 24 months
For DM there is the convenient Haemoglobin A1c (HbA1c) level, which is put forward by the American Diabetes Association (ADA) and International Diabetes Federation (IDF) as indicative of the metabolic state: prediabetes (HbA1c: 39-47 mmol/mol) and diabetes (HbA1c: ≥48 mmol/mol).
Risk of obstructive sleep apnea syndrome (OSAS)
时间窗: 24 months
For OSAS there is the recently developed OSAS risk questionnaire (Philips questionnaire), which scores patients into a low, high or severe risk category of having OSAS.The outcome will be on a percentage scale, varying from 0-100%. The cut-off point for being classified into the low risk category will be 35% and the cutt-of point for the severe risk category is 55%. Between 35 and 55%, participants are classified as high risk for OSAS.
Prevalence of metabolic syndrome (MetS)
时间窗: 24 months
The diagnostic criteria for MetS are based on the waist circumference (WC), triglycerides (TG), HDL-C, hypertension and dysglycemia (according to the NCEP ATP III). Any 3 of these 5 measures constitute diagnosis of metabolic syndrome. The outcome will be: 1. Absence of MetS (when ≤ 2 measures are met for the criteria of MetS) ; 1. Presence of MetS (when ≥ 3 measures are met for the criteria of MetS).
10-year-risk of atherosclerotic cardiovascular disease (ASCVD)
时间窗: 24 months
For ASCVD there is the "10-year-risk" chart, based on age, gender, total cholesterol, HDL cholesterol (HDL-C), LDL cholesterol (LDL-C), systolic and diastolic blood pressure, smoking, presence of diabetes and rheumatoid arthritis (according to the NHG standards, which are the European Society of Cardiology guidelines modified to the Dutch population). The 10-year risk of death or disease by ASCVD can be: Low = \<10%, Middle = 10-20%, High = \>20%.
