Suzukawa M, et al. - Herein, researchers investigated if baseline serum cytokine levels could predict responsiveness to omalizumab, a humanized anti-IgE monoclonal antibody, in patients with severe, persistent asthma. Findings suggested that as predictors of a good omalizumab response in severe asthmatics, high baseline serum CXCL10 and IL-12 levels may be useful.
