1. BACKGROUND                                               fatigue, eosinophilia, clubbing and increased acute phase

    Idiopathic pulmonary fibrosis (IPF) is an interstitial
chronic pulmonary disease, which affect patients older          There is no clear consensus about patients’
than 50 years old. Disease aetiology is unknown, but has    classification. The mild, moderate and severe terms are
been associated with risk factors such as tobacco           used depending on symptoms and function tests, although
consumption, viral infections, environmental pollution,     only mild-to-moderate IPF has been characterized (Forced
drug and genetic predisposition (1-2). Estimated incidence  Vital Capacity (FVC) =50%, Diffusion of Carbon Dioxide
varies between 7 and 16 cases/100000 inhabitants/year,      (DLCO) =35% (6)). Despite the mild diagnosis, medium-
with a prevalence ranging between 14 and 43                 term prognosis is poor, with a median survival between
cases/100000 inhabitants (3).                               two and four years after diagnosis. Respiratory failure is
                                                            the most common cause of death (40%). Other causes of
    IPF is characterized by an abnormal histopathological   death in patients with IPF include heart failure, ischemic
mesenchymal cell proliferation, fibrosis, overproduction    heart disease, infection, and pulmonary embolism. Age
and disorganized collagen deposition, extracellular matrix  under 50 years, female gender, preserved lung function
changes with distortion of pulmonary architecture and       and increased proportion of lymphocytes (20-25%) in
appearance of subpleural cysts (honeycomb cysts), with      bronchoalveolar fluid have been associated with more
accumulation of myofibroblast and fibroblast (3-5). In      survival (7). Age over 70 years, Comorbidities (pulmonary
early stages, clinical pattern is similar to other lung     hypertension), emphysema and lung cancer), DLCO under
diseases; signs and symptoms is unproductive cough,         40%, FVC decrease=10% and DLCO decrease=15%
