Rationale: Recently, antifibrotic therapy has been approved in idiopathic pulmonary fibrosis (IPF). In this study, we aimed to evaluate effectiveness, safety and tolerability of pirfenidon therapy in Turkish patients with IPF. Methods: In this retrospective study, we were evaluated 60 IPF patients who were taking pirfenidon at least for 6 months. IPF was diagnosed by clinical and radiology and/or histopathology. Patient characteristics, symptoms, pulmonary function tests (FVC, DLCO), 6-minute walk test (6-MWT) and effectiveness of therapy (stability or progression of the disease defined as decline of FVC (≥10%) at baseline and after 6 months of drug therapy), side effects, any hospitalization and mortality were recorded. Results: Of 60 IPF patients, 44 (73.4%) were male. While 46 (76.7%) IPF patients were stable during therapy course, 14 (23.3%) IPF patients had progressed according to decline in FVC ≥ 10%. During 6 months of antifibrotic therapy, in 9 (15.0%) IPF patients had exacerbation, and in 10 (16.7%) patients had all-cause hospitalization and one (1.7%) patient died. At least one side effect due to therapy were encountered in 33 (55.0%) IPF patients. Leading side effects were gastrointestinal symptoms (n=21, 35.0%) and photosensitivity (n=8, 13.3%). While in 16 (26.7%) patients, therapy dose was decreased, in only one (1.7%) patients therapy was discontinued due to intolerability. Conclusions: We concluded that pirfenidone therapy for IPF was effective and tolerable, and also had relatively acceptable side effects in our Turkish patients with IPF.
