Abstract
Introduction
Familial pulmonary fibrosis (FPF) is defined as an idiopathic diffuse parenchymal lung disease affecting two or more members of the same primary biological family. The aim of this study was to compare disease progression and tolerance to pirfenidone in a population of FPF patients who presented with radiological and/or histological evidence of UIP, and a group of idiopathic pulmonary fibrosis (IPF) patients.
Methods
Seventy-three patients (19 with FPF and 54 with IPF) were enrolled and data were collected retrospectively at 6, 12 and 24 months follow-up.
Results
FPF patients were statistically younger and more frequently females. A significantly greater decline in FVC and DLCO was recorded in FPF than in IPF patients at 24 months follow-up. At the 6-min walking test, walked distance declined significantly in FPF patients than IPF at 24 months. No statistically significant differences in drug tolerance or side effects were recorded between groups.
Conclusion
Different rate of progression was observed in patients with IPF and FPF on therapy with pirfenidone; our findings may not be due to lack of effectiveness of therapy, but to the different natural history and evolution of these two conditions. Pirfenidone was well tolerated by FPF and IPF patients. Specific unbiased randomized clinical trials on larger populations to validate our preliminary exploratory results are needed.
