Table 9.
Prevalence of IgE Anti-Staphylococcus aureus Enterotoxin (Superantigen) in the 3 Study Cohorts
| Cohort | Number | IgE anti-SEA >0.1 kUa/L | IgE anti-SEB >0.1 kUa/L | IgE anti-TSST >0.1 kUa/L | IgE anti-SEA, SEB, or TSST >0.1 kUa/L | IgE >0.35 kUa/L |
|---|---|---|---|---|---|---|
| Cohort A | 49 | 2 (4.0%) | 2 (4.0%) | 7 (14.2%) | 9 (18.3%) | 3 (6.1%) |
| Cohort B | 48 | 3 (6.2%) | 2 (4.1%) | 8 (16%) | 1 (20.8%) | 2 (4.1%) |
| Cohort C | 46 | 1 (2.1%) | 3 (6.5%) | 11 (24%) | 11 (23.9%) | 5 (10.8%) |
No significant difference in the levels of IgE antibodies between the cohorts (Mantel-Haenszel chi square). Ig, immunoglobulin; SEA(B), Staphylococcus aureus enterotoxin A(B); TSST, toxic shock syndrome toxin.
