They were given 2-4 weekly subcutaneous omalizumab for more than six months changes in nasal symptoms were noted using nasal symptoms score. Each symptom was individually evaluated.ResultsThere were 42 patients, consisting of 36 women (85.7%) and six men (14.3%), who received omalizumab treatment. Patient age ranged between 30 and 77 years, mean = 54.21±10.85 years. Median change in nasal symptom score of all cases after treatment was a 3.5 (2-6.25) decrease, which was statistically significant (p <0.001). When we examine the decrease in nasal symptoms after omalizumab compared to pre-omalizumab in all cases, the most prominent change was observed in the symptom of nasal congestion.ConclusionTwo-four weekly subcutaneous omalizumab for six months or more was effective in treating all rhinitis symptoms and had the greatest effect on nasal congestion compared to all other symptoms.
