Idiopathic pulmonary fibrosis (IPF) is a disease with progressive and devastating deterioration of lung function and a fatal prognosis, despite aggressive therapeutic attempts, which, in the majority of cases are futile.
Recently, a preliminary study of long-term treatment with interferon (IFN)- 1b and low-dose prednisolone in patients with IPF suggested that IFN- 1b treatment may improve lung function parameters of patients with IPF. Ever since, specialists in respiratory medicine who treat patients with IPF, are called by patients demanding treatment with IFN- 1b. Therefore, the authors here present another prospective investigation of IFN- 1b in five patients with IPF.
According to the previously published design, patients received 200 µg IFN- 1b subcutaneously three-times per week and 10 mg prednisolone orally for 12 months. Two patients stopped IFN- 1b treatment after 4 months due to side-effects and further lung function deterioration and one patient died 3 months after commencement of therapy. In total, pulmonary function improved in only one patient during IFN- 1b treatment, while four patients deteriorated.
To conclude, this small series of idiopathic pulmonary fibrosis cases treated with interferon- 1b and corticosteroids does not support previous data that this treatment improves pulmonary function or alters the natural course of idiopathic pulmonary fibrosis. Furthermore, in the authors' experience, side-effects of interferon- 1b treatment can significantly reduce patients' quality of life.
