Toxic Shock Syndrome
Toxic shock syndrome is a group of rapidly progressive and severe symptoms that include fever, rash, dangerously low blood pressure, and failure of several organs. It is caused by toxins produced by Staphylococcus aureus or group A streptococci.
Using superabsorbent tampons or having an infection caused by Staphylococcus aureus or group A streptococci increases the risk of this syndrome.
The syndrome can be fatal, particularly when caused by streptococci.
Changing tampons frequently and not using superabsorbent tampons can help reduce the risk of the syndrome.
Treatment focuses on relieving symptoms and preventing production of more toxin.
Toxic shock syndrome results from toxins produced by two types of bacteria:
This syndrome may occur when Staphylococcus aureus infects tissue (for example, in a wound) or is simply growing on a tampon (especially the superabsorbent type) in the vagina. Exactly why superabsorbent tampons increase the risk of this syndrome is unknown. Leaving a diaphragm in the vagina for more than 24 hours also increases the risk slightly.
This syndrome may also occur in the following situations:
Toxic shock syndrome symptoms and prognosis vary depending on whether staphylococci or streptococci are the cause.
With either organism , symptoms develop suddenly and worsen rapidly over a few days. Blood pressure falls to dangerously low levels, and several organs (such as the kidneys, liver, heart, and lungs) malfunction or stop functioning (called organ failure). People may have a high fever, a red and sore throat, red eyes, diarrhea, and muscle aches. Some become delirious. A rash that resembles sunburn covers the entire body, including the palms and soles. Then, the skin sometimes peels. Fluid accumulates in tissues, causing swelling (edema). Blood does not clot normally, making bleeding more likely and more severe.
In streptococcal toxic shock syndrome , the infected wound, if present, is painful. Gangrene may develop around the wound. Difficulty breathing due to respiratory failure ( acute respiratory distress syndrome) is common. Even with treatment, 20 to 60% of people die.
Staphylococcal toxic shock syndrome is often less serious. Fewer than 3% of people die. Skin peeling, particularly on the palms and soles, is more common. If people survive, recovery is usually complete.
When the source is a tampon infected by staphylococci, the syndrome may recur, usually within 4 months of the first episode. Occasionally, the syndrome recurs more than once. Each episode tends to be milder. To reduce the risk of recurrences, women who have had the syndrome should not use tampons or diaphragms.
The diagnosis is usually based on the symptoms and results of a physical examination and routine blood tests.
Samples of blood and infected tissue are also sent to a laboratory where bacteria can be grown (cultured).
Magnetic resonance imaging (MRI) or computed tomography (CT) may be done to locate sites of infection.
Blood tests are done regularly to monitor how well organs are functioning.
Women who use tampons can take several measures to prevent infection:
Women who have had toxic shock syndrome due to staphylococci should probably not use tampons and cervical caps, plugs, or diaphragms.
Otherwise, there are no recommendations for preventing toxic shock syndrome.
If toxic shock syndrome is suspected, people are hospitalized, usually in an intensive care unit.
Fluids that contain salts and often drugs to increase blood pressure to normal levels are given intravenously. Many people need help with breathing, usually with a mechanical ventilator. Tampons, diaphragms, and other foreign objects are removed from the vagina promptly. Antibiotics and, for severe cases, immune globulin (which can neutralize the toxin) are given intravenously. Areas that could contain the bacteria, such as surgical wounds and the vagina, are flushed out with water (irrigated).
If wounds are infected, surgery may be needed to clean them out further, to remove infected tissue, or sometimes, if gangrene has developed, to remove a limb.
