ABSTRACT
The presence of Staphylococcus aureus producing toxic shock toxin (TST) and the absence of antibody to TST (anti-TST) in acute-phase sera are markers for toxic shock syndrome (TSS). We used radioimmunoassay methods to examine 133 acute-phase and 277 convalescent-phase serum specimens from 181 patients with TSS for anti-TST. Among confirmed menstrual cases, nine (9.5%) of 95 patients had demonstrable anti-TST in acute-phase sera obtained during the first seven days of illness; patients with probable or non-menstrual TSS had a higher prevalence of anti-TST in acute-phase sera. Five (33.3%) of 15 individuals with confirmed menstrual TSS developed anti-TST as early as seven to nine days after TSS onset; 32 (62.7%) of 51 patients had demonstrable anti-TST in sera obtained more than one year after their episode of TSS. This study demonstrates a gradual rate and low magnitude of development of anti-TST after TSS and supports the diagnostic usefulness of measuring anti-TST levels in sera from patients suspected of having TSS.

Staphylococcal enterotoxin F (SEF) has previously been shown to be a marker for toxic-shock syndrome (TSS)-associated strains of Staphylococcus aureus, whereas the serologic absence of antibody to SEF (anti-SEF) has been shown to be a marker for susceptibility of persons to TSS. In this study, anti-SEF was measured by radioimmunoassay in 689 banked sera obtained from Wisconsin residents during 1960, 1970, and 1980. The prevalence of anti-SEF as estimated by logistic regression analysis was 47%, 58%, 70%, 88%, 96%, and 99% at ages one, five, 10, 20, 30, and 50 years, respectively. Evidence for the transplacental transfer of anti-SEF is also presented. Despite the reported increased incidence of TSS occurring during the past five years, with a preponderance of cases occurring among women, no significant differences in the prevalence of anti-SEF were noted between sexes or longitudinally between the years 1960, 1970, and 1980. These data enhance our understanding of the epidemiology of TSS and further identify the population that may be susceptible to TSS.

In 1980, the discovery of an association between vaginal tampon use and toxic shock syndrome affected the lifestyles of menstruating women and the catamenial products industry. It made both the general public and the medical community more aware of all aspects of menstruation. The relation between developing toxic shock syndrome and tampon use is unclear; tampon fluid capacity (absorbency) remains the best predictive measure of that risk. No unique aspect of tampon use other than absorbency seems to increase the risk of developing toxic shock syndrome, and numerous hygiene and medical history factors do not seem to play a role in the pathogenesis of the disease. Studies in Minnesota, Wisconsin, and Iowa indicate that 70% to 75% of women between the ages of 15 and 24, the group with the highest risk of developing menstrual toxic shock syndrome, continued to use tampons after news media attention in 1980 on the association of the syndrome with tampon use. This rate of use is higher than the rate found for the general population by recent tampon market research.
