Nationwide study of mortality and survival in pregnancy-related streptococcal toxic shock syndrome.
2020
Aim Streptococcal toxic shock syndrome is associated with the highest infection-related maternal mortality rates. We conducted a comparative analysis of the background factors and treatment course between survivors and nonsurvivors to improve our understanding concerning the optimal initial treatment approach for this fulminant disease. Methods This retrospective observational study was conducted based on clinical data collected from two national organizations. Clinical data of patients who died or survived (i.e. background information, clinical course and treatment administered) were collected. Results Records of 13 dead and 15 surviving patients were collected and analyzed. No statistically significant differences were found between the groups regarding age, parity, season, gestational age or the patients' location at the onset of symptoms. After the initial symptom onset, the survivors received antibiotics more systematically during their first visit to a clinic (P = 0.006). More survivors had received treatment within 1 h of onset of fulminant disease (P = 0.069). The number of fetal deaths was significantly higher in the mortality group (P = 0.003), while the fetal survival number was higher in the group of maternal survivors (P = 0.055). Maternal survivors with nonspecific initial symptoms received early intervention when there was a family history of group A streptococcal infection or a positive rapid antigen test result. Conclusion Intensive care, including systemic antibiotic administration, may contribute to maternal survival when administered immediately (within 1 h) after the fulminant streptococcal toxic shock syndrome onset. Eliciting a family history of streptococcal infection and conducting a rapid antigen test can identify the patients needing early intervention.
