Undiagnosed cases of fatal Clostridium-associated toxic shock in Californian women of childbearing age.

OBJECTIVE

In 2005, 4 Clostridium sordellii-associated toxic shock fatalities were reported in young Californian women after medical abortions. The true incidence of this rare disease is unknown, and a population-based study has never been performed. Additional clostridia-associated deaths were sought to describe associated clinical characteristics.

STUDY

DESIGN

Population-based death certificate review and a clinical case definition for clostridial-associated toxic shock identified women with likelihood of dying from a Clostridium infection. Formalin-fixed autopsy tissues underwent immunohistochemical and polymerase chain reaction assays.

RESULTS

Thirty-eight women were suspected of having C sordellii-associated death. Five tested positive for Clostridium species: 3 for Clostridium perfringens, 1 for C sordellii, and 1 for both. Deaths occurred after the medical procedures for cervical dysplasia (n = 2), surgical abortion (n = 1), stillborn delivery (n = 1), and term live birth (n = 1). None had a medical abortion.

CONCLUSION

C sordellii and C perfringens are associated with undiagnosed catastrophic infectious gynecologic illnesses among women of childbearing age.
