Churg-Strauss syndrome, an uncommon condition, occurs even more rarely in a
ssociation with pregnancy. One month postpartum, a 25-year-old Japanese wom
an was hospitalized for dyspnea, fever, diarrhea, and complaints of dysesth
esia in the right lower limb and right lumbar and abdominal region. Marked
eosinophilia was present. Symptoms of bronchial asthma had developed early
in the pregnancy; which concluded with delivery of a healthy baby at 39 wee
ks of gestation, Churg-Strauss syndrome was diagnosed and prednisolone was
administered with a good response leading to remission. Three years after t
he first pregnancy, low-dose steroid therapy was continued through another
pregnancy. The patient delivered another healthy baby at 39 weeks of gestat
ion, this time with no exacerbation of symptoms.
