Serum Sickness

Serum Sickness

This little Morsel stems from a intellectually fun conversation with Dr. Modisett (for those of you overseas, Dr. Modisett is one of our brilliant and illustrious Chief Residents at Carolinas – yes, I am spoiled).  This is another great reason to discuss not throwing antibiotics at every kid with an ear.

Serum Sickness Basics

  • Serum Sickness is considered a Type III hypersensitivity reaction.
    • Follows the administration of Foreign Proteins or Chemicals.
    • Antigen-antibofy complexes get deposited along the basement membranes of small vessels.
  • An inflammatory response occurs that leads to joint, skin, and systemic manifestations.
  • The true pathophysiology is unclear.
  • It is a self-limited condition, but the presentation can be quite dramatic and concerning to families.
    • 50% of children, in one study, required hospitalization due to severe symptoms.

     

Serum Sickness Presentation

  • Serum Sickness and “Serum Sickness-Like Reactions” are similar in presentation.
  • Fever
  • Rash (most often uricaria)
  • Arthralgias/Arthritis
  • Malaise
  • Lymphadenopathy
  • Proteinuria
  • Serum Sickness – Like Reaction

    • Often used when referring to medication associated reactions.
    • Differs from Serum Sickness in that it infrequently has associated proteinuria and lymphadenopathy.
    • More often reported in children.
    • More likely to occur during or following a second course of antibiotics (particularly Cefaclor).
    • Often occurs within the first 1 to 3 weeks after initiation of the offending drug.

 

Serum Sickness Causes

  • Anti-venom created from Horse Serum.
    • Historically, the term was derived the administration of Horse Serum that had been given to treat Diptheria. Ah, yes… the good ol’days.
  • Antibiotics
    • Penicillins / Amoxicillin
    • Cefaclor
    • Cefprozil
    • Cefazolin
    • Ciprofloxacin
    • Minocycline
  • Thiazide Diuretics
  • Many other medications.

 

Serum Sickness Treatment

  • Steroids and antihistamines have been used — no real data to show utility.
  • Stop offending agent!
  • Give analgesics!
  • Supportive care.

I enjoy taking care of patients and I finding it endlessly rewarding to help train others to do the same. I trained at the Combined Emergency Medicine and Pediatrics residency program at University of Maryland, where I had the tremendous fortune of learning from world renown educators and clinicians. Now I have the unbelievable honor of working with an unbelievably gifted group of practitioners at Carolinas Medical Center. I strive every day to inspire my residents as much as they inspire me.
