  1. Acute Rhinosinusitis – bacterial infection or inflammation?  Prof. Dr. Philippe GevaertDienst Neus-, keel- en oorheelkundeAllergienetwerk UZ-Gent

  2. New definition and classification • Update on literature and treatments • New and practical treatment schemes • acute rhinosinusitis adults • children • chronic rhinosinusitis adults • children • nasal polyposis • Research needs and priorities

  3. Definitions and classification for General Practice • Based on symptoms: • Two or more symptoms, one of which should be either • nasal blockage/obstruction/congestion or • nasal discharge: anterior/post nasal drip; • ± facial pain/pressure, • ± reduction or loss of smell • Examination: anterior rhinoscopy • X-ray/CT not recommended • * DURATION • ACUTE / intermittent < 12 weeks • complete resolution of symptoms • CHRONIC / persistent > 12 weeks • incomplete resolution of symptoms • Special attention to questions on allergic symptoms

  4. Definitions and classification • Based on symptoms: • Two or more symptoms, one of which should be either • nasal blockage/obstruction/congestion or • nasal discharge: anterior/post nasal drip; • ± facial pain/pressure, • ± reduction or loss of smell • AND EITHER • endoscopic findingsof polyps • mucopurulent discharge • edema or obstruction • OR • CT scan abnormality: mucosal changes • within ostiomeatal complex or sinus cavity

  5. Definitions and classification CLASSIFICATION OF RHINOSINUSITIS * SEVERITY Visual Analogue Scale (VAS) mild 0-3 moderate 3-7 severe 7-10 * DURATION ACUTE / intermittent < 12 weeks complete resolution of symptoms CHRONIC / persistent > 12 weeks incomplete resolution of symptoms

  6. Headache/facial pressure in sinusitis

  7. Nasal Endoscopy

  8. Imaging of sinsuses • RX sinuses: - Waters, Caldwell an Hirtz • - poor sensitivity and specificity • - NOT RECOMMENDED!

  9. Imaging of sinsuses • MRI: only recommended in tumor diagnosis • CT sinuses: current standard imaging (50mGy) • Cave! radiation damage of lens (500-2000mGy) • - Acute rhinosinusitis: only if signs for complications!! • Chronic sinusitis: only after 4w-12w treatment!

Least common adenovirus

  12. Pathophysiology Viral Rhinitis Impact of viral infection on the mucosa • Epithelial changes • Hypersecretion and oedema •  Goblet cells (hypersecretion),  ciliated cells (secretion stasis) • Cell destruction with vasodilatation (cavernous sinuses!) • Release inflammatory mediators from inflammatory cells • Seromucous hypersecretion and exudation  Thickening lamina propria

  13. Symptoms Viral Rhinitis • Quickly passing sore throat: viral pharyngitis, swollen throat • Nasal symptoms: congestion, sneezing, rhinorrhea  gone after 7 d, mucus production peaks on d 3 and 4 • Coughing: longest lasting symptom,  weeks in smokersand patients with reflux! • 1/10: short headache • Rarely tremors, general malaise • Note: more serious problems with anatomical anomalies (deviated septum) or children: otitis, rhinopharyngitis, sinusitis, tracheitis, bronchitis

  14. Symptoms Viral Rhinitis

  15. Cough after Viral Rhinitis (smoking)

  16. Complications after Viral Rhinitis

  17. Therapeutical Options Common Cold • Nothing • Local vasoconstrictors: preferably only at night, not > 7d • Physiological flushing: mainly with children or with anatomical anomalies • Note: other types of rhinitis where physiological flushing -possibly supplemented with ointment application- may be useful: occupational rhinitis, rhinitis due to irritants, atrophic rhinitis • Antibiotics: useless, unless complication due to surinfection

  21. Microbiology Normal sinuses: Free of growth Acute rhinosinusitis: 2/3 Viral 1/3 Bacterial (St Pneumoniae,H Influenzae, M Catharralis) Chronic rhinosinusitis: >>Anaerobes: Propionibacterium, Bacteriodes, Peptococcus Aerobes:Staphylococcus, Corynebacterium, Pseudomonas Fungi (» aspergillus fumigatus) Dentogene sinusitis: ?

  22. Guidelines for Acute Rhinosinusitis • Commoncold/ Acute viralrhinosinusitis Occurence in adults: up to 4 times a year URTI: symptoms < 10 days Symptomatictreatmentonly: • Decongestants • Pain relief • Saline drops Can lead to post-viral inflammation of nose and sinuses

  23. Guidelines for Acute Rhinosinusitis • Acute post-viral Rhinosinusitis (ARS) Definition: • ↑symptomsafter 5 daysor • persistent symptomsafter 10 days • lessthan 12 weeks Symptoms: • Nasalobstruction/congestion and/or • Facial pain/pressure • Accompaniedby: • Nasal discharge and/or • Reductionor loss of smell

  24. Guidelines for Acute Rhinosinusitis • Acute post-viral Rhinosinusitis (ARS) Occurence: • onceor more thanonce in defined time period (episodes per year) • complete resolutionbetweensymptoms Appearance: • Mild • Severe • Fever > 38,3°C • Localized pain over the sinuses Streptococcus pneumoniae, Haemophilusinfluenzae and Moraxellacatarrhalis May lead to complications !!

  25. Strength of evidence for treatment of Acute Rhinosinusitis

  26. DBPC trial in 95 patients with acute sinusitis (with history of CRS) All received 2x/d xylometazoline spray (3days) and 2 x 250mg/d cefuroxime (10 days) 47 patients 200µg (two puffs) Fluticasone or 48 patients placebo spray Dolor et al. JAMA Oct 2002
