BACKGROUND: The antifibrotic agents pirfenidone and nintedanib have been shown to be effective in patients with idiopathic pulmonary fibrosis (IPF). However, discontinuation of antifibrotic drugs is a major clinical concern because of the lack of alternative treatment options. Therefore, we identified factors that may be useful for predicting the termination of antifibrotic agents.
METHODS: We retrospectively recruited 280 IPF patients treated with antifibrotic drugs between 2009 and 2018 from seven regional core hospitals in Gunma prefecture, Japan.
RESULTS: At four months, the short-term discontinuation group exhibited a significantly worse prognosis in the pirfenidone group and a poorer prognosis in the nintedanib group compared to that in the continuation group. The discontinuation group of pirfenidone at 4 months exhibited lower albumin and higher C-reactive protein (CRP) levels in the sera compared to the group that continued treatment for more than 4 months. In multivariate analysis, the Glasgow prognostic score (GPS), well known as a predictor of cancer prognosis, which comprises serum CRP and albumin levels, predicted early discontinuation and prognosis in the pirfenidone group, whereas the body mass index (BMI) predicted early discontinuation of nintedanib. A high GPS, with both albumin <3.5 g/dL and CRP >1.0 mg/dL, was associated with a poorer prognosis in the pirfenidone group.
CONCLUSION: GPS and BMI were significant factors for short-term pirfenidone and nintedanib discontinuation, respectively. Initial evaluation of GPS and BMI prior to antifibrotic therapy may contribute to less interrupted IPF management, thus leading to better prognostic outcomes in patients with IPF.
