In eight cases combination therapy was discontinued and steroid therapy was initiated. While dosage and length of steroid treatment was highly variable, most authors started at a relatively high dosage. Intravenous therapy with 180 mg/day methylprednisolone was started in one case [14] , while other authors started with 125 mg/day prednisolone [15, 16] . Others started patients on oral steroid therapy (40 mg) [6, 17, this study], while two authors initiated inhalation steroids [18, 19] .
