Abstract

Microbial infections and mucosal dysbiosis influence morbidity in patients with systemic lupus erythematosus (SLE). In the oral cavity, periodontal bacteria and subgingival plaque dysbiosis provide persistent inflammatory stimuli at the mucosal surface. This study was undertaken to evaluate whether exposure to periodontal bacteria influences disease parameters in SLE patients. Circulating antibodies to specific periodontal bacteria have been used as surrogate markers to determine an ongoing bacterial burden, or as indicators of past exposure to the bacteria. Banked serum samples from SLE patients in the Oklahoma Lupus Cohort were used to measure antibody titres against periodontal pathogens (Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, and Treponema denticola) and commensals (Capnocytophaga ochracea, and Streptococcus gordonii) by ELISA. Correlations between anti-bacterial antibodies and different clinicalparameters of SLE including, autoantibodies (anti-dsDNA, anti-SmRNP, anti-SSA/Ro and anti-SSB/La), complement, and disease activity (SLEDAI and BILAG) were studied. SLE patients had varying amounts of antibodies to different oral bacteria. The antibody titres against A. actinomycetemcomitans, P. gingivalis,...Continue Reading

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.
