Improvement of quality of life in allergic rhinoconjunctivitis patients using nasal filters, a preliminary study.

ABSTRACT

BACKGROUND: Allergic rhinoconjunctivitis is a clinical condition that impairs quality of life. The use of traditional drugs in many cases is not enough to improve quality of life in these patients. METHODS: In this pilot study we used the Sanispira Nasal filters in 15 patients (mean age 34,7 years) affected by allergic rhinoconjunctivitis for 18 days. At each follow-up visit, patients were assessed with a specific quality of life questionnaire, a symptoms form and a drugs form that evaluates the use of antiallergic drugs in the last week. Patients sensitive to environmental allergens wore Sanispira nasal filters during the day, while patients sensitive to domestic allergens wore the device during the night. RESULTS: Thirteen patients completed the study. We found an improvement significative (p=0,0241) of the total score of RQLQ of 23,10 points between baseline and 18 days ( total score at baseline prior to nasal filter insertion= 60,60, at 1 week = 42, 28, at 18 days= 34, 10). A significative improvement in the nasal symptoms domain between baseline and 18 days (in particular stuffy nose p=0,047; runny nose p=0,012; sneezing p=0,0021; ) and one item of practical problems domain, the need to repeatedly blow the nose(p=0,082). The total score of symptoms evaluated with the symptoms form improved significantly from baseline to 18 days. Total symptoms score at baseline was 9,7; at 1 week it was 8,1 and at 18 days it was 4,7. The improvement was statistically significant (p=0,0092). Three of the thirteen patients that completed the study eliminated completely the use of drugs during of the study. CONCLUSIONS: The use of SANISPIRA ®, has shown encouraging results, with an improvement in the quality of life in Rhinoconjunctivitis patients specially an improvement in nasal and ocular symptoms.
