Serological Response to Toxic Shock syndrome Toxin in Staphylococcus Aureus Infected Pathients and Healthy Controls
2009
The prevalence of antibodies to Toxic Shock Syndrome Toxin (TSST-1) in a Swedish healthy control population was investigated using an enzyme-linked immunosorbent assay (ELISA). 88% of the control group above the age of 10 showed positive antibody levels as compared to 31% of those who were under 10 years old. These results indicate a very common normal exposure to TSST-1 during early life and also identify the small risk-group of potential TSS-patients. Patients with S. aureus endocarditis and septicemia showed slightly higher antibody levels as compared to the controls (p< 0.05). The difference was in part due to 3/4 septicemia patients, infected with TSST-1 producing strains, who showed very high antibody levels. None of these 4 patients developed any signs of TSS. 5/5 menstrual associated TSS-patients were negative in the ELISA in serial serum samples as were 3/5 non-menstrual associated TSS-patients. The TSST-1 ELISA is proposed for identifying chiefly young women at risk of acquiring menstrual related Toxic Shock Syndrome.
