Toxic shock syndrome

Toxic shock syndrome (TSS) is a rare but potentially fatal disease caused by a bacterial toxin. Different bacterial toxins may cause toxic shock syndrome, depending on the situation. The causative agent is Staphylococcus aureus. A similar condition, therefore called Toxic Shock Like Syndrome (TSLS), is the result of Streptococcus pyogenes infection more...

Point of Entry

The route of infection is usually through the skin (pricking accident, surgery, burns), vagina (tampon, partus) or pharynx.

The number of reported toxic shock syndrome cases has decreased significantly in recent years. Approximately half the cases of TSS reported today are associated with tampon use during menstruation, usually in young women, though TSS also occurs in children, men, and non-menstruating women. In the US in 1997 only five confirmed menstrually-related TSS cases were reported, compared with 814 cases in 1980, according to data from the Centers for Disease Control and Prevention (CDC).

Although scientists have recognized an association between TSS and tampon use, no firm causal link has been established. Research conducted by the CDC suggested that use of some high absorbency tampons increased the risk of TSS in menstruating women. A few specific tampon designs and high absorbency tampon materials were also found to have some association with increased risk of TSS. These products and materials are no longer used in tampons sold in the U.S. Tampons made with rayon do not appear to have a higher risk of TSS than cotton tampons of similar absorbency.

Vaginal dryness and ulcerations may occur when women use tampons more absorbent than needed for the amount of their menstrual flow. Ulcerations have also been reported in women using tampons between menstrual periods to try to control excessive vaginal discharge or abnormal bleeding. Women may avoid problems by choosing a tampon with the minimum absorbency needed to control menstrual flow and using tampons only during active menstruation. Alternately, women may use a silicone menstrual cup to avoid the negative side-effects of tampons.

Symptoms and diagnosis

Symptoms of toxic shock syndrome in the early phase can be hard to recognize because they mimic the flu. They include sudden high fever, muscle aches, joint pain, vomiting, diarrhea, dizziness, fainting, or a rash that looks like a sunburn. One or two weeks after initial symptoms begin, flaking and peeling of the skin occurs, mainly on the palms and soles.

The fulminant course rapidly changes general symptoms to fever, systolic blood pressure under 90 mmHg, altered state of mind. In other words, septic shock.

Therapy

Women wearing a tampon at the onset of symptoms should remove it immediately. The severity of this disease results in hospitalisation for treatment. Antibiotic treatment consists of Penicilline and Clindamycin.

Extreme infection of the skin and deeper parts is called Fasciitis necroticans, (one of the symptoms), and should be attacked surgically without delay.

Postinfluenza toxic shock syndrome
From CHEST, 5/1/89 by G.C. Prechter

Postinfluenza Toxic Shock Syndrome (*1)

In 1978, toxic shock syndrome (TSS) was described as a multisystem illness capable of producing fever, hypotension, and rash, with eventual desquamation. [1] The syndrome was later associated with exotoxin-producing Staphyococcus aureus infection usually occurring in women in relation to tampon use. However, non-menstrual TSS has occurred in a variety of other clinical sitations, including respiratory tract infections. There are three reports [2-4] documenting 11 cases in which an influenzalike illness was followed by S aureus respiratory tract infection complicated by TSS. These recently published accounts raise speculation that a syndrome of postinfluenza TSS may be emerging. [4] The following report presents the clinical features of such a case and highlights the importance of respiratory tract involvement in toxic shock syndrome.

CASE REPORT

A 19-year-old man with a four-day history of nonproductive cough, sore throat, and nasal congestion presented with acute deterioration characterized by a productive cough, dyspnea, diarrhea, myalgias, and disorientation. Physical examination revealed an erythematous macular rash over the extremities, chest, and abdomen; pharyngeal erythema with a strawberry tongue; bilateral conjunctival injection; blood pressure 90/50 mm Hg, pulse 150, respirations 30, and temperature 40.6[degrees]C. The abnormal laboratory values included a white blood cell count of 26,000/cu mm, proteinuria, calcium 7.5 mg/dL, creatinine 1.7 mg/dL, aspartate aminotransferase 84 U/L (10-37), alanine aminotransferase 72 U/L (12-39), lactate dehydrogenase 316 U/L (118-242), and creatine kinase 675 U/L (35-185). The arterial blood gas levels on room air demonstrated [Po.sub.2], 44 mm Hg; [Pco.sub.2], 25 mm Hg; and pH, 7.53. The chest x-ray film showed a faint right lower lobe infiltrate (Fig 1) and minimal changes in the left lower lobe. Results of blood, CSF, urine, stool, and throat cultures were negative; purulent sputum produced a pure growth of penicillin-resistent S aureus. Serologic studies were negative for Mycoplasma, Legionella, psittacosis, Rocky Mountain spotted fever, cytomegalovirus, adenovirus, influenza A and C, and parainfluenza. Antiobidies to influenza B were present acutely at a titer of 1:128.

The patient was admitted to the intensive care unit and started on therapy with erythromcyin and nafcillin. He was adequately oxygenated on 50 percent oxygen concentration delivered by face mask and received intravenous fluids, keeping his systolic blood pressure above 100 mm Hg. The symptoms and physical findings showed improvement within four days, and normalization of the laboratory data and chest x-ray film was seen by day 10 of hospitalization. Desquamation of skin over the palms and soles occurred during recovery, appearing most prominently on the sole (Fig. 2). He was discharged in good health on day 12.

DISCUSSION

There is no diagnostic test for toxic shock syndrome. Case definition requires the presence of specific clinical manifestations. The Centers for Disease Control criteria [5,6] include fever, diffuse erythorderma with subsequent desquamation, hypotension, and multisystem involvement. Additionally, blood, throat, and cerebrospinal fluid cultures, as well as serologic studies for Rocky Mountain spotted fever, leptospirosis, and rubeola should be negative if obtained. Positive TSS toxin assays are not necessary for diagnosis. This case fulfills these criteria, including laboratory documentations of systemic illness with elevated creatinine, aspartate aminotransferase, alanine aminotransferase, creatine kinase and thrombocytopenia.

Combining data from this patient and the 11 previously reported cases [2-4] of postinfluenza TSS reveals the following points. The age range was five to 56 years (mean 24) with six males and six females. All had respiratory symptoms and eight of ten had evidence of pneumonia on chest x-ray examination. Two died before hospitalization with no prior chest x-ray examination and their autopsy findings demonstrated tracheitis without pneumonia. [3] Therefore, eight of 12 (67 percent) had evidence of pneumonia. five of five tested had positive cultures or serologies for influenza B. Positive S aureus sputum cultures were seen in 11/11 as a result of purulent tracheitis or pneumonitis. Nine of nine yielded positive TSS toxin assays for either toxin-1 or enterotoxin B. Desquamation, which is an unnecessary criterion for a confirmed case of TSS if the patient dies within two weeks, occurred in seven of 12 (58 percent). The patients who did not display desquamation had died early in their clinical course, so that their findings may not yet have developed. Specific therapeutic regimens were described in four of 12; all of these received antistaphylococcal antibiotics and three of four survived. Overall, fatal outcome was reported in six (50 percent).

These cases appear to define a new syndrome of postinfluenza TSS, although the recognition of this entity may have its origins in antiquity. In fact, before the first such case was reported, Langmuir et al [7,8] theorized that the historic plague of Athens which began in 430 BC was due to toxin-producing S aureus during an influenza epidemic. These authors have suggested the term "Thucydides syndrome" for this disease process in honor of the Athenian general, Thucydides, who documented the effects of the illness extensively. It is of interest that the change or reappearance of bacterial strains and their association with toxic syndromes is not unique to S aureus; rather, this phenomenon has been described most recently with group A streptococcal infections as well. [9,10]

The association of postinfluenza TSS with only influenza B outbreaks may be coincidence. However, this complication of influenza B has now been reported from four geographically separate locations during two different flu seasons and has not been recognized in association with influenza A or other viral illness. Despite the observation that influenza B outbreaks result in milder disease than those caused by influenza A, it appears that the complication of TSS is being seen exclusively with influenza B to date.

Although TSS is an uncommon complication of influenza, a watchful attitude during the influenza season is warranted, perhaps especially when influenza B is prevalent. TSS should be considered in the differential diagnosis of individuals who become critically ill following an initial influenzalike illness, since specific therapy for proven, or unproven but presumed S aureus, may yield a favorable outcome in this highly lethal syndrome.
