Biomarker aids asthma control in pregnant women

Algorithm leads to fewer exacerbations in those with non-eosinophilic disease, researchers say

Researchers led by Professor Peter Gibson from the University of Newcastle and John Hunter Hospital, have demonstrated how to optimise treatment for this group in a reanalysis of data from the Australian Managing Asthma in Pregnancy (MAP) trial reported in the Lancet in 2011.
