To analyse which rheumatic syndromes are associated with serological evidence of recent Staphylococcus aureus infection, we studied retrospectively 44 adult patients, gathered between 1979-1990, having an acute arthritis syndrome or an exacerbation in their chronic rheumatic disease and simultaneously a high antistaphylolysin (ASTA > 4,0) and/or high teichoic acid antibody titre (TAA > 8). Patients with septic arthritis or endoprosthetic infections were not included. 25 patients had arthritis/arthralgia associated with a known rheumatic disease, 9 patients had reactive arthritis and 8 patients had arthralgia. The frequency of HLA-B27 in tested patients was significantly higher in the whole patient group than in the healthy Finnish population (43% v 14%, p < 0.001). It is concluded that high ASTA and/or TAA titres are associated with various acute rheumatic syndromes including reactive arthritis.
