Introduction: Atopic patients with severe asthma frequently have poorly controlled disease despite intensive treatment. These patients are frequently treated with oral corticosteroids which can results in  serious side-effects. Anti-IgE antibody had been used in severe persistent allergic asthma. However, its long-term efficacy in patients in India has not been reported.

Aim: Anti-IgE antibody had been used in severe persistent allergic asthma in adults. Here we are presentating our experience of 30 patients with 52 weeks of Anti IgE Therapy follow-up.

Method and Materials: 30 (16 male and 14 female) patients, with mean age of 49 having severe persistent allergic asthma with recurrent exacerbations and having oral/ IV/ high dose ICS (Inhaled Corticosteroids) who received Omalizumab 300mg once a month for 6 month to 1 year were included in the study. Total dose of oral Steroids, use of rescue medications, changes in lung function ( FEV1) and ICS dose were recorded at the baseline, 16 weeks and at 52 weeks.

Results: There was significant reduction in use of oral steroid at 16 week and 52 weeks -10.5mg  and 22.5mg respectively . Use of rescue medications decreased by -7.90 puffs (p- <0.001) at 16 weeks and by -13.67 puffs (p -<0.001) at 52 weeks. Improvements in lung Function ( FEV1) observed was 700 ml from Base Line after 52 weeks therapy. ACT Score showed significant improvement at 16 wks and at 52 wks.

Conclusion: Use of anti-IgE antibody for 1 year led to significant improvement in patients with severe persistent allergic asthma.
