A) Background: Know the causes of nasal and bronchial symptoms persistence in patients with Samter's syndrome under treatment in a period of time
B) Methods: Cohort study. Inclusion criteria: Patients with asthma diagnoses, hypersensitivity to aspirin and nasal polyps. Exclusion criteria: Other kind of asthma, COPD. Twelve patients were followed from June 2009 to June 2011.
Nasal and bronchial symptoms were assessed every 6 months using the Visual Analogue Scale of severity (VAS) from EPOS guidelines and spirometry from GINA.
All were treated with intranasal mometasone furoate 200mcg at day, montelukast 10 mg at day, salmeterol plus fluticasone 50/100 powder 2 inhalation every 12hrs, fluticasone spray 150mg every 12hrs, loratadine tablet 10mg if was necessary, with modifications of doses every 3 months.
Patients diagnosed at 6 months with sinusitis and nasal polyposis were administered amoxicillin plus clavulanate 1.5 gr daily for 5 weeks. The patients without response at 6 and 18 months were prescribed clarithromycin 400mg daily for 4 weeks.
All patients underwent CT of the sinuses through the Lund-Mackay system, chest CT scan, skin prick test. Evaluated by otolaryngology to the 6, 12, and 18 months.
C) Results: In the 98.2% had negative skin prick tests. At 6 months, 58.3% had nasal symptoms with VAS <7 . At 33.3% reported bronchial relapses with FEV1 <80.
At year nasal symptoms increased, with WAS> 7 in 66.6%. The bronchial relapse decreased to 16,6%
At year and a half it increased nasal symptoms in 75% of patients, with VAS> 7. At 41,6% had obstruction of 100% and pansinusitis. They needed antibiotic scheme.
At two years in 83.3% had a VAS> 7. At 58.3% had pansinusitis. The bronchial relapse did not increase
We determined the presence of VAS> 7 and pansinusitis (OR = 4). The bronchial relapse did not influence with increasing VAS (OR = 1).
D) Conclusions: Nasal symptoms persistent were secondary to the nasal polyps and pansinusitis with higher levels of VAS. It was determinated a 4-fold risk over pansinusitis with a VAS> 7 (OR = 4). It should be stressed the palliative surgical treatment in earlier stages and desensitization protocols.
