BACKGROUND AND AIM: Idiopathic pulmonary fibrosis (IPF) is a lung disease of unknown cause, characterized by inflammation. Neutrophil, lymphocyte, monocyte and platelet count ratios indicate chronic inflammation rather than individual cell populations. Biomarkers are important in assessing disease risk, early diagnosis, prognosis and treatment response. We aimed to analyze haematological indices as indicators of inflammation in newly diagnosed IPF patients and compare them with healthy controls and patients receiving antifibrotic therapy.
