A case of recurrent polymyalgia rheumatica-like complications with pregnancy

We encountered a 26-year-old Japanese woman with recurrent episodes of polymyalgia rheumatica-like symptoms associated with pregnancy. At a 13-week pregnancy, she was admitted to our outpatient clinic, complaining of myalgia on both thighs, shoulders and upper limbs. Laboratory examinations of blood yielded normal creatine kinase and mild elevation of erythrocyte sedimentation rate. After administration of oral prednisolone (10 mg/day) was begun, her symptoms were gradually resolved by 1 week. Further epidemiologic studies should be needed.
