Toxic Shock Syndrome
Caring for the child in shock is challenging! Vascular access has to be attained. Fluids have to be given quickly and Vasopressors may need to be started early! Certainly, the airway must be evaluated and, occasionally, secured. All of this occurs while we juggle the potential causes (ex, Sepsis, Hypovolemia, Obstructive processes, Cardiogenic, “K“ortisol). For children, the potential for an infectious etiology is always high, but this may warrant more consideration than “just give them all of the antibiotics we have!” Do not overlook the potential for bacterial TOXINS causing more problems for the patient! Let’s take a moment to review Toxic Shock Syndrome:
Toxic Shock Syndrome: Basics
- Toxic Shock Syndrome (TSS) is: [Javouhey, 2018]
- Severe, acute illness
- May begin with non-specific symptoms (GI particularly). [Javouhey, 2018; Rodriguez-Nunez, 2011]
- Rapid clinical deterioration follows.
- Characterized by:
- High Fever
- Hypotension
- Rash (ex, erythroderma, scartletiniform, intertrigo)
- Multi-Organ System Dysfunction (ex, Altered Mental Status, Renal dysfunction)
- Desquamation (during convalescence)
- Severe, acute illness
- TSS is difficult to diagnose as the characteristics may be transient, absent, or delayed in presentation. [Javouhey, 2018]
- Often not initially recognized. [Javouhey, 2018; Deniskin, 2018; Rodriguez-Nunez, 2011]
- Clindamycin (part of recommended therapy) was not given as part of initial therapy in a substantial portion of cases of TSS. [Gaensbauer, 2018; Deniskin, 2018; Rodriguez-Nunez, 2011]
- TSS is caused by SUPERantigen ExoTOXINS. [Javouhey, 2018]
- Superantigens directly stimulate T cells
- They do not need to be processed by antigen-presenting cells.
- Superantigens lead to massive polyclonal cell proliferation!
- Superantigens can be produced by both Staph and Strep.
- Superantigens are very potent.
- Superantigens directly stimulate T cells
- TSS should be considered in critically ill children with:
- Erythroderma
- Conjunctival Hyperemia
- Strawberry tongue
- Known nidus of infection (ex, tampon, nasal / wound packing)
- TSS may look very similar many other conditions like:
- Septic Shock
- Kawasaki Disease Shock Syndrome
- Drug Reaction w/ Eosinophilia and Systemic Symptoms (DRESS) Syndrome
- TSS can be caused by Staphylococcus or Streptococcus.
- Staphylococcus is the most common etiology of TSS. [Gaensbauer, 2018; Javouhey, 2018]
- Staph TSS more frequently occurs in older, female patients associated with menstruation.
- Staph TSS does, however, also occur in males and other aged children.
- Streptococcal TSS is less common overall, but: [Gaensbauer, 2018; Javouhey, 2018]
- Strep TSS is more common in younger children (~47% of patients < 2 years of age)
- Strep TSS is more clinically severe.
- TSS associated with para-pneumonic empyema is suggestive of strep etiology.
- Other risk factors for Strep TSS include: [Rodriguez-Nunez, 2011]
- Previous surgery
- Skin Wounds
- Trauma
- Recent Viral Infection (ex, Varicella Zoster, Influenza) [Rodriguez-Nunez, 2011]
- NSAID use
- Premature birth
- Congenital heart disease
- Immune Suppression
- Staphylococcus is the most common etiology of TSS. [Gaensbauer, 2018; Javouhey, 2018]
Toxic Shock Syndrome: Management
- Rapid recognition and initiation of treatment of Septic Shock is critical to helping to support good outcomes. [Gaensbauer, 2018]
- Recognition of shock is challenging in children – Assess Cap Refill!
- Rapid diagnostic testing can be helpful (although an elevated Lactate can be from other conditions).
- Aggressively volume resuscitate!
- “Timely” initiation of broad spectrum antibiotics (many protocols call from them to be given within the 1st 60 min).
- Toxic Shock Syndrome was estimated in ~11% of all septic shock cases. [Gaensbauer, 2018]
- In addition to the above, optimal treatment of Toxic Shock Syndrome should include: [Gaensbauer, 2018; Javouhey, 2018]
- Elimination of any nidus of toxin-producing staph or strep
- Removal of foreign bodies (ex, tampons, nasal packing)
- Surgical drainage of abscess / deep space infection
- Reduction of toxin production / exposure
- Antibiotics like Clindamycin, Rifampin, or Linezolid interfere with exotoxin production. [Javouhey, 2018]
- Some data support use of IVIG to neutralize the Superantigens. [Javouhey, 2018]
- Elimination of any nidus of toxin-producing staph or strep
- It is important to ensure that Clindamycin (or another exotoxin production inhibitor) is added to your broad-spectrum antibiotics selected based on your regional antibiogram. [Rodriguez-Nunez, 2011]
Moral of the Morsel
- Some bugs are really vicious! The weapons that Staph and Strep possess are quite impressive and aggressive!
- Keep Toxic Shock Syndrome on your list! You may be correct in diagnosing that cause of the shock is infection, but don’t overlook the possible circulating bacterial exotoxins!
- Fight the Toxins! Add Clindamycin to your protocoled antibiotic selections.
