In medicine, pharyngitis is an upper respiratory tract infection that is "inflammation of the throat (pharynx)."[1]

Causes

Viral

The majority of pharyngtis is caused by viral infection.

Bacterial

Group A β-hemolytic streptococcus (streptococcus pyogenes).

Fusobacterium necrophorum may be as common as group A β-hemolytic streptococcus and can cause Lemierre syndrome.[2] Lemierre syndrome is "suppurative thrombophlebitis of the internal jugular vein, bacteremia, and metastatic infections."</ref>

Chemical and physical agents

Diagnosis

Diagnosis has been reviewed by the Rational Clinical Examination who noted the Centor criteria.[3]

Centor criteria:[4]

  • fever
  • No cough
  • Tonsilar exudate
  • Tender anterior cervical lymph nodes

The McIsaac criteria adds to the Centor:[4]

  • Age less than 15: add one point
  • Age greater than 45: subtract one point

According to the Centers for Disease Control and Prevention:

  • 0 points: do not test nor treat
  • 1 points: do not test nor treat
  • 2 points: rapid test and treat if positive
  • 3 points
    • Option 1: rapid test and treat if positive
    • Option 2: treat empirically
  • 4 points: treat empirically

Differential diagnosis

  • Angioedema [r]: Allergic skin reaction causing localized redness, swelling, and itching. [e]

Pharyngitis caused by Fusobacterium necrophorum may lead to Lemierre syndrome.[2]

Treatment

Antibiotics may be used for patients with sufficient likelihood of streptococcal infection.[5]

Losenges with amylmetacresol and 2,4-dichlorobenzyl alcohol may help.[6]

Corticosteroids, such as prednisone 60 mg by mouth for one or two days may reduce symptoms among patients with severe pharyngitis.[7][8]
