Recurrent sore throat

Definition/Description

  • Inflammation of the oropharynx. This can be chronic, lasting for more than a month. It can be relapsing recurrent acute pharyngitis or tonsillitis.
  • Maybe due to a recurrent pharyngitis or tonsillitis, for details of tonsillitis see the tonsillitis guideline.
  • It can be due to persistent infections such as candida, rhinosinusitis, or recurrent tonsillitis or dental infections.
  • It can be associated with chronic irritants such as smoking, alcohol, environmental irritants and reflux associated with obesity
  • It can be associated with mouth breathing from polyps or deviated nasal septum or allergic rhinitis
  • It can be confused with globus and caused by laryngopharyngeal reflux- see Globus document.
  • It can be associated with a tumour.

Red Flag Symptoms

  • Unilateral swelling at the back of the throat.
  • Dysphagia - Persistent sore throat particularly with unilateral features and other risk factors such as age, smoking, alcohol.
  • Sore throat lasting more than 6 weeks with no cause found should be referred urgently to ENT.
  • Low grade sore throat with unilateral otalgia

Guidelines on Management

Management

  • Encourage smoking cessation
  • Encourage weight loss (if appropriate)
  • A sore throat is most often a self-limiting disease and most often viral in origin. Usually simple OTC the counter remedies are all that is required for pain relief.
  • Centor score is helping in determining when to prescribe antibiotics.
     

Centor criteria

  • The Centor criteria was developed to predict bacterial infection (GABHS) in people with acute sore throat. The four Centor criteria are:
    • Presence of tonsillar exudate.
    • Presence of tender anterior cervical lymphadenopathy or lymphadenitis.
    • History of fever.
    • Absence of cough.
  • The presence of three or four of these clinical signs (Centor score 3 or 4) suggests that the person may have GABHS (40–60% chance) and may benefit from antibiotics treatment.
  • The absence of three or four of these signs suggests that the person is unlikely to have an infection (80% chance), and antibiotics treatment is unlikely to be necessary.
  • In the UK throat swabs are not usual practice as for a simple sore throat the specificity of a swab is 70% and the sensitivity is 30%.
  • Consider other non-infective causes of the persistent sore throat.
  • Consider a prolonged antibiotic treatment for 10 days. Please refer to North Yorkshire Antibiotic Guidance – acute sore throat.
  • First line: Phenoxymethylpenicillin 500mg QDS for 10 days
  • Alternative (penicillin allergy): Clarithromycin 250 – 500mg BD for 5 days
  • If persistent consider swab to rule out unusual bacteria or fungal infection.
  • Discuss smoking and alcohol and reflux (consider treatment with sodium alginate – e.g. Peptac®. This can be purchased OTC).
