Take Home Points

  • Acute rhinosinusitis is a clinical diagnosis
  • The vast majority of acute rhinosinusitis cases are viral in nature and do not require antibiotics
  • Consider the use of antibiotics in select groups with severe disease or worsening symptoms after initial improvement.

REBEL Core Cast 121.0 – Acute Sinusitis

Definition:

  • Acute rhinosinusitis (ARS) – Symptoms for less than four weeks
  • Subacute rhinosinusitis – Symptoms for 4 to 12 weeks
  • Chronic rhinosinusitis – Symptoms persisting greater than 12 weeks
  • Recurrent acute rhinosinusitis – Four or more episodes of ARS per year, with interim symptom resolution

Epidemiology: (Anon 2004)

  • 20 million cases of sinusitis annually in the US, costing $3.5 billion/year
  • Source of 1 in 5 antibiotic prescriptions for adults

Presentation:

  • Sinusitis is most commonly diagnosed by clinical symptoms
  • Common symptoms
    • Purulent nasal discharge
    • Nasal congestion
    • Facial pain or pressure, especially over a sinus or unilaterally
    • Anosmia
    • Hyposmia
    • Fever
    • Cough
    • Fatigue
    • Maxillary pain
    • Ear pressure or fullness.

Classification of Sinusitis:

●Acute viral rhinosinusitis (AVRS)

  • ARS with viral etiology (i.e. rhinovirus, influenza, and parainfluenza)
  • Most common form of ARS

●Uncomplicated acute bacterial rhinosinusitis (ABRS)

  • ARS with a bacterial etiology without clinical evidence of extension outside the paranasal sinuses and nasal cavity
  • Bacterial superinfection: 0.5-2% of all ARS

●Complicated acute bacterial rhinosinusitis

  • ARS with bacterial etiology with clinical evidence of extension outside the paranasal sinuses and nasal cavity

Sinusitis: Viral vs. Bacterial:

  • Color change in sputum does not determine whether infection is viral or bacterial
  • Viral infections
    • Tend to begin resolution by 7-10 days
    • Rarely have associated fevers
    • If fever present, usually only in the first 48 hours.
  • Guidelines for diagnosing ABRS are
    • Presence of URI/cold symptoms that
        • Don’t improve after 10 days
        • Worsen after 5-7 days of improvement
      • Severe symptoms including high fever, purulent discharge or facial pain for 3-4 days

The Data Behind Antibiotic Use

    • Clinically diagnosed acute sinusitis
        • Multiple studies show the same cure rate at 7 days, but improved cure rate at 7-14 days for those who use antibiotics (Lemiengre 2012, Berg 1986, Gwaltney 1996)
        • Overall Treatment Effect NNT = 18
        • Overall Harm NNH = 8 (mostly GI side effects)
      • Radiographically-diagnosed acute sinusitis (Ahovuo-Saloranta 2008)
        • Endpoint: clinical cure at 7-15 days
        • NNT = 15
        • NNH = 8

IDSA Recommendations for Antibiotic Treatment (Chow 2012)

  • Patients that should be treated
    • Persistent symptoms w/o improvement (> 10 days)
    • Severe symptoms (> 3-4 days)
    • Worsening (“double-sickening”) (> 3-4 days)
  • Antimicrobials
    • 1st Line
      • Amoxicillin 875 mg PO BID X 5-7 days
      • Doxycycline 100 mg PO BID X 5-7 days
    • 2nd Line
      • Amoxicillin/Calvulanate 875/125 mg PO BID X 5-7 days
      • Levofloxacin 500 mg PO Q24 X 5 days

Bottom Line: Given the risk for adverse events associated with antibiotic use, the growing specter of resistance and the lack of significant differences in outcomes with antibiotic use, it is better to avoid antibiotics in most patients with ARS. Antibiotics should be considered in those with severe disease and in immunocompromised patients

Take Home Points

  • Acute rhinosinusitis is a clinical diagnosis
  • The vast majority of acute rhinosinusitis cases are viral in nature and do not require antibiotics
  • Consider the use of antibiotics in select groups with severe disease or worsening symptoms after initial improvement.
