UC Davis pulmonary specialists and WAF Board Members Samuel Louie and Amir Zeki have named asthma-COPD overlap syndrome, or ACOS.
The physicians recognized the high incidence of the condition — defined by the increased number and intensity of symptoms — after evaluating UC Davis patients with obstructive lung diseases and finding that ACOS was present in about a quarter of patients with severe asthma. They also observed that, on average, 1 in 5 patients with obstructive lung diseases have ACOS.
