2 CLASSIFICATION OF ILDs CHRONIC WITHOUT SYSTEMIC DISEASE (Idiopathic interstitial Pneumonias, CEP,LAM Alv proteinosis, PVOD) CHRONIC WITH SYSTEMIC DISEASE (vasculitis, CVD Sarcoidosis) ACUTE ( A I P, A EP,H P) ILD > 500 SUBACUTE ( COP,H P) EPISODIC (HP, vasculitis, COP, EOS. PNEUMONIA) CHRONIC KNOWN ETIOLOGY (Environmental, Occupational, Drugs)

3 AJRCCM 2013 Idiopathic interstitial pneumonias (IIP) Idiopathic pulmonary fibrosis/usual interstitial pneumonia (IPF/UIP) Nonspecific interstitial pneumonia (NSIP) Cryptogenic organizing pneumonia (COP/OP) Desquamative interstitial pneumonia (DIP) Respiratory bronchiolitisassociated interstitial lung disease (RBILD) Acute interstitial Pneumonia (AIP) RARE IIPs 55% 25% 3% 15% 3%

4 Current Definition of IPF Distinct chronic progressive fibrosing interstitial pneumonia of unknown cause, primarily occurring in older adults, is limited to the lungs, and has typical imaging and pathologic findings of UIP ATS/ERS/JRS/ALAT Statement. Am J Respir Crit Care Med. 2011;183:

31 Vote: 4 for the use of BAL, 18 against the use of BAL, 1 abstention, 8 absent.)

32 50% of chp patients were misdiagnosed as IPF BAL provides us vital information on degree of alveolitis treatment response

33 The new guidelines for IPF diagnosis (ATS/ERS/JRS/ALAT) Transbronchial biopsy (TBB) Desirable effects of TBB Less burdensome More efficient Undesirable effects of TBB 53% lower diagnostic yield 22% less likely to acquire adequate specimen For patients with newly diagnosed ILD of unknown cause who are clinically suspected of having IPF and who have a HRCT pattern other than consistent with UIP, we recommend / suggest that TBB be performed / not be performed.

34 The new guidelines for IPF diagnosis (ATS/ERS/JRS/ALAT) Cryobiopsy Desirable effects of cryobiopsy Approximately 96% of surgical lung biopsies may be avoided. 5.7% fewer respiratory infections. 1.5% less procedural mortality. Undesirable effects of cryobiopsy 8.5% lower diagnostic yield 4.4% more bleeding 11.5% more pneumothorax 7.5% more prolonged air leak For patients with newly diagnosed ILD of unknown cause who are clinically suspected of having IPF and who have a HRCT pattern other than consistent with UIP, we recommend / suggest that Cryobiopsy be performed / not be performed.

35 The new guidelines for IPF diagnosis (ATS/ERS/JRS/ALAT) Surgical lung biopsy (SLBx) Desirable effects of SLBx Adequate sample obtained in 100%. Diagnostic yield of 90%. Undesirable effects of SLBx 3.5% overall mortality 1.7% procedural mortality 6.1% develop exacerbations 5% develop pneumothorax 5.9% develop prolonged air leak 6.5% develop a respiratory infection 4.5% develop neuropathic pain 3% have delayed wound healing Biopsy in selected cases = 30% (unclassified IPAF) For patients with newly diagnosed ILD of unknown cause who are clinically suspected of having IPF and who have a HRCT pattern other than consistent with UIP, we recommend / suggest that surgical lung biopsy be performed / not be performed.

37 The new guidelines for IPF diagnosis (ATS/ERS/JRS/ALAT) Multidisciplinary team discussion (MDD) vs single discipline discussions (SDD) in patients who are clinically suspected of having IPF Favoring MDD over SDD Avoid incorrect therapy, delayed therapy, and unnecessary diagnostic testing or therapy in approximately 30% of patients. Favoring SDD over MDD Less burdensome More efficient Diagnosis should be made based on MDT Walsh et al. Eur Respir J 2017; 50:
