  • Background The impact of severe asthma on patients� quality of life (QoL) has been previously demonstrated, as well the difficulties in controlling the disease. We aimed to evaluate the effect of omalizumab on QoL and asthma control, and its safety and tolerability in real-life conditions in Portugal.

    Methods Prospective and open-label study in 15 adult patients with uncontrolled severe persistent allergic asthma on omalizumab treatment ?16 weeks (w). The short (at 16 w) and long-term (at 1 and 2 years) (y) effects of omalizumab were assessed through the Asthma Life Questionnaire (ALQ) and the Asthma Control Test (ACT). Other secondary outcomes were evaluated.

    Results A significant reduction in ALQ total score (at 16 w, p = 0.002; at 1 y, p = 0.033 and at 2 y, p = 0.024), as well as in the �non-scheduled medical visits� and the �medication use� domains in both the short and long terms was observed. Regarding ACT, we verified a significant improvement in total score (at 16 w, p = 0.004; at 1 y, p = 0.004 and at 2 y, p = 0.008) and in almost all of the five individual questions. Asthma exacerbations and unscheduled health care visits were significantly decreased. There was a significant rise in lung function and a decrease in daily inhaled steroids dose. The most frequent adverse effects were headaches and nausea.

    Conclusions Omalizumab promoted a global benefit on QoL and asthma control outcomes. It also yielded a reduction in asthma exacerbations and unscheduled health care visits, a steroid-sparing effect, and an improvement in lung function. The drug was found to be generally safe and well-tolerated.
