Clinical and molecular characteristics of infective β-hemolytic streptococcal endocarditis
چکیده انگلیسی
Streptococcus pyogenes (S. pyogenes) and Streptococcus dysgalactiae subspecies equisimilis (SDSE) cause considerable morbidity and mortality, and show similarities in disease manifestations and pathogenic mechanisms. Their involvement in infective endocarditis, however, has not been well described. Invasive S. pyogenes and SDSE infections in Health Region Bergen, Norway, in the period 1999-2013 were reviewed, and sixteen cases of endocarditis were identified. The median duration of symptoms was 2.5 days, the frequency of embolic events 50%, 38% received valve replacement and the 30-day mortality was 25%. In S. pyogenes, a significant correlation was observed between the repertoire of fibronectin-binding genes, phenotypic binding ability to fibronectin and disease manifestations. Conversely, no associations between phenotypic and genotypic characteristics were detected in SDSE. S. pyogenes and SDSE endocarditis is characterized by rapid and severe clinical manifestations. The pathogenesis is multifactorial, but our results infer a potential role of fibronectin binding in the development of S. pyogenes endocarditis.
