Study Notes
Rhinosinusitis and Nasal Polyps
- Acute rhinosinusitis (ARS) is typically preceded by a viral upper respiratory tract infection and usually does not require antibiotic treatment
- Less than 4% of ARS cases need antibiotics for bacterial infections
- Chronic rhinosinusitis (CRS) affects 10-15% of the general population in the US and EU
- CRS is more common in patients with allergic rhinitis and smokers
- CRS is often associated with higher rates of airway comorbidities, such as asthma
- CRS has two main phenotypes: with and without nasal polyps
- Remodeling in CRS is mainly regulated by transforming growth factor-β (TGF-β)
- CRS with nasal polyps (CRSwNP) is characterized by hyperplastic, edematous remodeling with a lack of transforming growth factor-β (TGF-β) signaling and collagen deposition
- Underlying conditions like allergic rhinitis, cystic fibrosis (CF), immune deficiency, or primary cilia dyskinesia can cause sinusitis
- Severe inflammation can accompany aspirin sensitivity or comorbid asthma in CRS
- Topical or oral glucocorticosteroids and antibiotics are common medical treatments for CRS
- Surgery is considered only after drug treatment fails, but drug treatments are still often necessary post-surgery
- Biotherapeutics, such as dupilumab, omalizumab, or mepolizumab, may be used for type 2 nasal polyp endotypes
- Biomarkers are needed to determine therapeutic responses
Acute and Chronic Rhinosinusitis Without Nasal Polyps
- Sinusitis is inflammation of the paranasal mucous membranes, often triggered by viral, bacterial, or fungal infections
- The diagnosis is based on symptoms, duration, and, when relevant, endoscopic and/or radiologic criteria
- Chronic rhinosinusitis (CRS) is diagnosed as symptoms lasting 12 or more weeks
- Structural changes like fibrosis of the ostiomeatal complex may be primary, with mucosal inflammation following
- This leads to ventilation/drainage impairment and persistent obstruction
- Underlying conditions like allergy, cystic fibrosis, or immune deficiencies can contribute to sinusitis development
Acute Rhinosinusitis
- ARS is sudden in onset and can last up to 12 weeks
- Symptoms typically peak in 2-3 days, gradually decreasing for 7-14 days
- Deviation from this pattern often indicates a non-viral cause
- Nasal congestion, discharge, facial pressure, and impaired smell are common signs and symptoms
- X-ray imaging is sometimes used in diagnosis, though it's often not necessary in diagnosis
Chronic Rhinosinusitis
- Diagnosed as having duration of twelve weeks or longer
- Symptoms generally are same as those in acute sinusitis, but persist for longer than 12 weeks
- Symptoms can be isolated, such as headache or postnasal drip, or more diffuse
Patient Evaluation and Diagnosis
- Detailed symptom evaluation, medical history, and comorbid assessments are essential for diagnosis
- Anterior rhinoscopy and nasal endoscopy are used to assess turbinates and nasal passages
- Ultrasound, CT scans, and MRIs may be used for further evaluation
