Staphylococcus Aureus Toxic Shock Syndrome Video

In an adult population, streptococcal toxic shock appears to be considerably more common than staphylococcal toxic shock syndrome. Staphylococcal toxic shock syndrome occurs predominantly among younger patients, because the vast majority of people develop antibodies to staphylococcal toxins by mid-adulthood. Consequently, in an adult ICU population the considerable majority of toxic shock presentations will result from streptococci. In some cases, clinical manifestations are dominated by toxin secretion, whereas in other cases the primary focus of infection may be more obvious. The differential diagnosis will vary depending on specific presentations. Some closer mimics may include:. We are the EMCrit Projecta team of independent medical bloggers and podcasters joined Staphylococcus Aureus Toxic Shock Syndrome by our common love of cutting-edge care, iconoclastic ramblings, and FOAM.

Staphylococcus Aureus. Toxic Shock Syndrome

This triggers a cascade of inflammatory cytokines similar to septic shockleading to multiorgan failure. Most people acquire antibodies that neutralize these toxins. Staphylococcjs minority of people lack these antibodies, rendering them vulnerable to toxic shock syndrome. This occurs in the context of an invasive streptococcal infection. The most common source is a soft-tissue infection Aurus. Group B streptococcus Streptococcus agalactiae is less commonly here with toxic Staphylococcus Aureus Toxic Shock Syndrome, but several reports suggest that it might cause toxic shock syndrome.

It often occurs due to mucosal colonization, without invasive infection. The most common focus of infection is soft tissue e. Toxic shock may result from any invasive infection, for example: Pneumonia and empyema Group A streptococcal pneumonia tends to cause empyema. Peritonitis Group A Streptococcus may cause a primary peritonitis, without underlying visceral organ pathology. Gynecological infections especially among pregnant or postpartum women : Chorioamnionitis, endometritis.

Postoperative obstetric infections often leading to necrotizing fasciitis.

Following minor gynecological procedures e. Invasive staphylococcal infections: Soft tissue infections — including burn infection, post-surgical, or postpartum wound infection.

Common examples: 1 Toxc episodes of menstrual-related staphylococcal toxic shock syndrome. Staphylococcal toxin suppresses neutrophil function, which may decrease the local signs and symptoms of infection! In streptococcal toxic shock, most patients will have an evident focus of infection often cellulitis or necrotizing fasciitis. In some cases, the primary focus may be subtle e.

Pain out of proportion to examination may signal necrotizing fasciitis. Most patients should not develop septic shock due to cellulitis. Patients may look OK and thereby elude initial diagnosis. This may be subtle, resembling a sunburn. In patients with darker skin, mucosal changes may be the most noticeable signs see figure below.

This frequently occurs at an earlier stage than in most types of septic shock, typically preceding hypotension. Consequently, patients may present with advanced acute kidney injury. However, this is often a later and ominous sign. Full-blown disseminated intravascular coagulation may be seen late in the course of illness.

Profound cytokine elevation may cause release of creatinine kinase from muscle tissue. However, another possibility to consider is necrotizing fasciitis.]
