Drug-related Churg-Strauss syndrome?
Churg-Strauss syndrome (CSS) is a rare disease belonging to the group of necrotizing vasculitides affecting medium and small vessels, classified together with Wegener granulomatosis and microscopic polyarteritis. The literature is reviewed concerning vasculitides associated with drug use, focusing on CSS. A representative case of CSS is reported, in whom the possibility could not be excluded that oestrogen replacement therapy contributed to the onset of CSS. The case of a 56-year-old female patient is presented who had a history of allergic rhinitis and steroid-dependent asthma for years. To prevent postmenopausal complaints and further loss of bone density, she received oestrogen replacement therapy. After three months of hormone therapy, signs of CSS appeared. Oestrogen administration (1 mg norethisterone acetate, 1 mg oestriol and 2 mg oestradiol daily) was stopped. The diagnosis was confirmed by the clinical appearance, laboratory tests and tissue biopsies. The patient received corticosteroids and cyclophosphamide treatment and subsequently the eosinophil count returned to normal within two weeks and her condition improved significantly.
