Asthma is one of the most common diseases complicating pregnancy and a risk factor for several maternal and fetal complications, posing a special challenge for physicians treating asthmatic pregnant women. Asthma influences the outcome of pregnancy and - vice versa - pregnancy affects asthma severity with bidirectional immunological interactions that are currently being examined. Supporting pregnancy-induced immunotolerance is the observation that attenuation of allergic responses can be detected in controlled asthmatic pregnant patients. However, uncontrolled asthmatic pregnant women show significant asthma-associated immune reactions, such as diminished pregnancy specific regulatory T cell proliferation, that may - besides other factors - influence fetal growth. Uncontrolled, symptomatic asthma may increase the risk of adverse perinatal outcomes; thus adequate regular anti-asthmatic treatment resulting in optimal asthma control represents a vital need during pregnancy. This review summarizes immunological changes characterizing pregnancy in asthmatic women together with the clinical implications of asthma management during pregnancy.
