[Toxic shock syndrome: experience in a pediatric intensive care unit]

To review patients with toxic shock syndrome (TSS) in a pediatric intensive care unit.

We performed a retrospective study of patients with TSS admitted to the intensive care unit in the previous 15 years. The patients included were those that met the clinical and microbiological criteria for TSS proposed by the Centers for Disease Control and Prevention.

There were nine patients (four boys). The mean age was 7 years. The most frequent findings were fever (100 %), hypotension (100 %), erythroderma (100 %), multisystem organ failure [coagulopathy (100 %), lethargy (89 %), hypertransaminasemia (89 %), increased creatine phosphokinase levels (78 %), renal failure (66 %)] and cutaneous desquamation (100 %). Laboratory studies showed changes in the leukocyte count and C-reactive protein value in all patients. The etiology was as follows: Staphylococcus was detected in six patients (S. epidermidis in three and S. aureus in three) and Streptococcus was detected in two patients (S. pyogenes in one and S. pneumoniae in one); no microorganisms were detected in only one patient. The origin of the infection was identified in seven patients (cutaneous in six patients and tonsillar in one). All patients received life support and antibiotic treatment. Six patients received corticosteroid treatment and one received intravenous immunoglobulins. Patients with TSS secondary to Streptococcus showed the greatest severity, exhibiting renal failure and requiring greater respiratory and circulatory support. All patients recovered well from the infection, without serious long-term sequelae. CONCLUSION. TSS should be included in the differential diagnosis of patients with fever, exanthema and shock, since early diagnosis has been shown to improve outcomes. S. pneumoniae should be included among the microorganisms that cause TSS. Treatment is based on life support measures and antibiotic therapy.
