There are few reports on the use of cyclosporine In idiopathic pulmona
ry fibrosis, in experimental animals or humans. We report three patien
ts with advanced pulmonary fibrosis in whom steroid therapy failed and
that received cyclosporine in a dose of 3 to 5 mg/kg for three to fiv
e months. One patient developed systemic hypertension that subsided re
ducing the dose of cyclosporine. No positive changes in dyspnea were o
btained and pulmonary function tests deteriorated during the treatment
period. We conclude that cyclosporine treatment had no clinical benef
it in these patients with pulmonary fibrosis.
