Of patients with asthma, 50% have concurrent sinus disease. Sinusitis is the most important exacerbating factor for asthma symptoms. Either acute infectious sinus disease or chronic inflammation may contribute to worsening airway symptoms. Treatment of nasal and sinus inflammation reduces airway reactivity. Treatment of acute sinusitis requires at least 10 days of antibiotics to improve asthma symptoms. [19]
