The objective of this study was to determine if a relationship exists between antibody reactive with the Actinobacillus actinomycetemcomitans serotype b lipopolysaccharide (LPS) and severity of periodontal disease in generalized early-onset periodontitis (G-EOP). The concentration of antibody reactive with A. actinomycetemcomitans serotype b LPS was determined for 102 G-EOP subjects. Analysis of the relationship between antibody reactive with A. actinomycetemcomitans serotype b LPS and measures of periodontal attachment loss indicated that the patients with the highest concentrations of antibody reactive with A. actinomycetemcomitans serotype b LPS had significantly less attachment loss. These high-responder subjects also had anti-A. actinomycetemcomitans serotype b LPS with significantly higher relative avidity. The results suggest that antibody reactive with A. actinomycetemcomitans serotype b LPS is protective in G-EOP patients.
本研究的目的是确定与伴放线放线杆菌b型血清型脂多糖(LPS)发生反应的抗体与广泛型早发性牙周炎(G-EOP)患者牙周疾病严重程度之间是否存在关联。测定了102例G-EOP患者血清中与伴放线放线杆菌b型血清型LPS发生反应的抗体浓度。对与伴放线放线杆菌b型血清型LPS发生反应的抗体和牙周附着丧失指标之间的关系进行分析,结果显示,血清中与伴放线放线杆菌b型血清型LPS发生反应的抗体浓度最高的患者,其附着丧失显著较少。这些高反应性受试者体内抗伴放线放线杆菌b型血清型LPS的相对亲和力也显著更高。结果表明,与伴放线放线杆菌b型血清型LPS发生反应的抗体对G-EOP患者具有保护作用。
