Fibrotic Lung Diseases

Progressive fibrosing interstitial lung disease (PF-ILD) describes a phenotypic subset of interstitial lung diseases characterized by progressive, intractable lung fibrosis. PF-ILD is separate from, but has radiographic, histopathologic, and clinical similarities to idiopathic pulmonary fibrosis. Two antifibrotic medications, nintedanib and pirfenidone, have been approved for use in patients with idiopathic pulmonary fibrosis. Recently completed randomized controlled trials have demonstrated the clinical efficacy of antifibrotic therapy in patients with PF-ILD. The validation of efficacy of antifibrotic therapy in PF-ILD has changed the treatment landscape for all of the fibrotic lung diseases, providing a new treatment pathway and opening the door for combined antifibrotic and immunosuppressant drug therapy to address both the fibrotic and inflammatory components of ILD characterized by mixed pathophysiologic pathways.

Broad Overview

The availability of epidemiological data relating to interstitial lung diseases (ILDs) has increased over recent years, but information on the prevalence and incidence of ILDs of different aetiologies remains limited. Despite global distribution, the proportion of patients who develop a progressive phenotype across different ILDs is not well known. Disease behaviour is well documented in idiopathic pulmonary fibrosis but idiosyncratic in other ILDs that may present a progressive fibrosing phenotype. Possible reasons may include the heterogeneous nature of the aetiology, the complexity of diagnosis (and subsequent documentation of cases) and the methods employed to retrospectively analyse patient databases. This review presents a broad overview of the epidemiological data available for ILDs that may present a progressive-fibrosing phenotype, collectively and stratified according to clinical classification. We also note where further data are needed in comparison to the well-studied IPF indication.

Pathologic Diagnosis

Idiopathic pulmonary fibrosis (IPF) represents one of the most common chronic interstitial lung diseases. Usual interstitial pneumonia (UIP) is the pathologic diagnosis of IPF and can be diagnosed when honeycombing is present with a basilar and peripheral predominance and findings not typical of UIP are absent. In the current era, when a diagnosis of UIP is made with confidence on HRCT, biopsy can be avoided. Yet, one must be familiar with mimics of UIP/IPF (most notably pulmonary edema superimposed on emphysema) to avoid confusion misdiagnosis. Radiologists must also be familiar with potential complications of UIP including progression, infection, accelerated fibrosis (which can be lethal) and primary lung cancer (which has an increased incidence in UIP).

BackgroundIdiopathic pulmonary fibrosis (IPF) is a well-characterised interstitial lung disease. Typically, IPF diagnosis is delayed due to nonspecific symptoms, but can also be delayed due to treatment attempts on false indication or due to treatment targeting common comorbidities. This observational study aimed to assess the dynamics in the medication and diagnosis patterns in the period before and after an IPF diagnosis.MethodsWe identified all Danish patients with IPF between 2002 and 2017. We evaluated new and ongoing drug treatments and incident diagnoses 36 months before and 12 months after an IPF diagnosis by use of Danish nationwide registries. To aid interpretation, 10 random controls were recruited for each case.ResultsA total of 650 IPF patients were identified (median age 73 years (interquartile range 65–78), 70.3% males). Prior to the IPF diagnosis, the most prevalent diagnoses were dyspnoea and non-IPF interstitial lung diseases. For drug use, IPF patients had higher initiation rates for antibiotics, oral corticosteroids and mucolytics. In terms of drug volume, IPF patients used more respiratory drugs, antibiotics, immunosuppressants, corticosteroids, proton pump inhibitors, benzodiazepines and opium alkaloids within the 6 months preceding their IPF diagnosis, compared to the controls. Overall drug use decreased after an IPF diagnosis, mainly due to a reduced glucocorticoid and cardiovascular drug use.ConclusionAmong IPF patients, an increased drug use was observed for diagnoses with symptoms overlapping those of IPF, particularly this was observed during the last 6 months before an IPF diagnosis. This emphasises the need for an increased IPF awareness.

End Stage

Idiopathic pulmonary fibrosis presents a progressive and heterogeneous functional decline. CA 19-9 has been proposed as biomarker to predict disease course, but its role remains unclear. We assessed CA 19-9 levels and clinical data in end-stage ILD patients (48 IPF and 20 non-IPF ILD) evaluated for lung transplant, to correlate these levels with functional decline. Patients were categorized based on their rate of functional decline as slow (n = 20; ΔFVC%pred ≤ 10%/year) or rapid progressors (n = 28; ΔFVC%pred ≥ 10%/year). Nearly half of the entire patients (n = 32; 47%) had CA 19-9 levels ≥37kU/L. CA 19-9 levels in IPF were not different from non-IPF ILD populations, however, the latter group had a median CA 19-9 level above the normal cut-off value of 37 KU/l (60 [17–247] kU/L). Among IPF patients, CA 19-9 was higher in slow than in rapid progressors with a trend toward significance (33vs17kU/L; p = 0.055). In the whole population, CA19-9 levels were inversely related with ΔFVC/year (r = −0.261; p = 0.03), this correlation remained in IPF patients, particularly in rapid progressors (r = −0.51; p = 0.005), but not in non. Moreover, IPF rapid progressors with normal CA 19-9 levels showed the greater ΔFVC/year compared to those with abnormal CA 19-9 (0.95 vs. 0.65 L/year; p = 0.03). In patients with end-stage ILD, CA 19-9 may represent a marker of disease severity, whereas its level is inversely correlated with functional decline, particularly among IPF rapid progressors.
