“…For example, Glurich (Glurich et al 2002), reporting data from the Erie County Periodontal Epidemiology Study, noted a hierarchy in levels of CRP, serum amyloid A and alpha 1-antichymotrypsin, wherein the highest levels were found in patients with both periodontitis and CVD compared to either condition alone. Other markers such as ceruloplasmin and sVCAM-1 were elevated only in CVD Serum levels increased in chronic periodontitis (CP) Ebersole et al 1997, Loos et al 2000, Slade et al 2000, Noack et al 2001, Offenbacher 2002, Ebersole et al 2002, Buhlin et al 2003, Beck and Slade et al 2003, Amar et al 2003, Yoshii et al 2009, Gomes-Filho et al 2011, Pejcic et al 2011, Serum levels increased in aggressive periodontitis Salzberg et al 2006, Sun et al 2009, Serum levels increased in patients with CVD and CP compared to either condition alone Glurich et al 2002, Persson et al 2005, Amabile et al 2008, Malali et al 2010, Liu et al 2010 PAF levels elevated in serum and gingiva, PAF-AH levels decrease following therapy Noguchi et al 1989, Losche et al 2005, Zheng et al 2006, Chen et al 2010 while some including sICAM-1 were not elevated. Similar observations have since been made in other populations, including a Chinese population with relatively low CRP concentrations (Liu et al 2010).…”
