Abstract
BACKGROUND Early detection of cardiac involvement in patients with sarcoidosis is important but currently unresolved. The aim of this study was to elucidate the utility of frequency domain microvolt T-wave alternans (TWA), signal-averaged ECG (SAECG), and heart rate turbulence (HRT) using 24-hour Holter ECG for detecting cardiac involvement in patients with pulmonary sarcoidosis. METHODS This study consisted of consecutive 40 pulmonary sarcoidosis patients (11 males, 62 ± 13 years) who underwent 24-hour Holter monitoring with and without cardiac involvement. All patients underwent frequency domain TWA, SAECG, and HRT using 24-hour Holter monitoring. Patients with atrial fibrillation pacing or wide QRS electrocardiogram were excluded. RESULTS After 14 patients were excluded, a total of 26 patients (six males, 59 ± 14 years) were evaluated. Seven patients had cardiac involvement (cardiac sarcoidosis [CS] group). On the Holter SAECG, duration of low-amplitude signals <40 μV in the terminal filtered QRS complex (LAS40) was significantly higher, and root mean square voltage of the terminal 40 ms of the filtered QRS complex (RMS40) was significantly lower in the CS group compared with the non-CS group (LAS40: 61.4 ± 35.9 vs 37.6 ± 9.2 ms; P = .018, RMS40: 11.4 ± 10.3 vs 23.6 ± 13.2 ms; P = .023). Prevalence of positive late potential (LP) was also significantly higher in the CS group than that in the non-CS group (85.7% vs 31.5%; P = .026). The sensitivity, specificity, positive, and negative predictive values of LP for identifying patients with cardiac involvement were 85.7%, 68.4%, 50.0%, and 92.8%, respectively. CONCLUSION Holter SAECG may be useful for detecting cardiac involvement in patients with pulmonary sarcoidosis.

Efficacy and safety of nintedanib in patients with systemic sclerosis-associated interstitial lung disease treated with mycophenolate: a subgroup analysis of the SENSCIS trial. THE LANCET RESPIRATORY MEDICINE 2021; 9:96-106. [PMID: 33412120 DOI: 10.1016/s2213-2600(20)30330-1] [Citation(s) in RCA: 99] [Impact Index Per Article: 33.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/17/2019] [Revised: 06/23/2020] [Accepted: 07/15/2020] [Indexed: 11/26/2022]
Abstract
BACKGROUND In the Safety and Efficacy of Nintedanib in Systemic Sclerosis (SENSCIS) trial, nintedanib reduced the rate of decline in forced vital capacity (FVC) in patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD). Patients on stable treatment with mycophenolate for at least 6 months before randomisation could participate. The aim of this subgroup analysis was to examine the efficacy and safety of nintedanib by mycophenolate use at baseline. METHODS The SENSCIS trial was a randomised, double-blind, placebo-controlled trial, in which patients with SSc-ILD were randomly assigned (1:1) to receive 150 mg of oral nintedanib twice daily or placebo for at least 52 weeks. In a prespecified subgroup analysis, we analysed the primary endpoint of rate of decline in FVC over 52 weeks by mycophenolate use at baseline. In a post-hoc analysis, we analysed the proportion of patients with an absolute decrease in FVC of at least 3·3% predicted at week 52 (proposed minimal clinically important difference estimate for worsening of FVC in patients with SSc-ILD) in subgroups by mycophenolate use at baseline. Adverse events were reported in subgroups by mycophenolate use at baseline. Analyses were done in all participants who received at least one dose of study drug. We analysed the annual rate of decline in FVC using a random coefficient regression model (with random slopes and intercepts) including anti-topoisomerase I antibody status, age, height, sex, and baseline FVC as covariates and terms for baseline-by-time, treatment-by-subgroup, and treatment-by-subgroup-by-time interactions. SENSCIS is registered with ClinicalTrials.gov, NCT02597933, and is now complete. FINDINGS Between Nov 30, 2015, and Oct 31, 2017, 819 participants were screened and 576 were enrolled, randomly assigned to, and treated with nintedanib (n=288) or placebo (n=288). 139 (48%) of 288 in the nintedanib group and 140 (49%) of 288 in the placebo group were taking mycophenolate at baseline. In patients taking mycophenolate at baseline, the adjusted mean annual rate of decline in FVC was -40·2 mL per year (SE 19·8) with nintedanib and -66·5 mL per year (19·3) with placebo (difference: 26·3 mL per year [95% CI -27·9 to 80·6]). In patients not taking mycophenolate at baseline, the adjusted mean annual rate of decline in FVC was -63·9 mL per year (SE 19·3) with nintedanib and -119·3 mL per year (19·0) with placebo (difference: 55·4 mL per year [95% CI 2·3 to 108·5]). We found no heterogeneity in the effect of nintedanib versus placebo on the annual rate of decline in FVC between the subgroups by mycophenolate use (p value for interaction=0·45). In a post-hoc analysis, the proportion of patients with an absolute decrease in FVC of at least 3·3% predicted was lower with nintedanib than with placebo in both patients taking mycophenolate (40 [29%] of 138 vs 56 [40%] of 140; odds ratio 0·61 [0·37 to 1·01]) and those not taking mycophenolate (59 [40%] of 149 vs 70 [47%] of 148; 0·73 [0·46 to 1·16]) at baseline. The adverse event profile of nintedanib was similar between the subgroups. Diarrhoea, the most common adverse event, was reported in 106 (76%) of 139 patients in the nintedanib group and 48 (34%) of 140 in the placebo group among those taking mycophenolate at baseline, and in 112 (75%) of 149 in the nintedanib group and 43 (29%) of 148 in the placebo group among those not taking mycophenolate at baseline. Over the entire trial period, 19 patients died (ten in the nintedanib group and nine in the placebo group). One death in the nintedanib group was considered to be related to study drug. INTERPRETATION Nintedanib reduced the progression of interstitial lung disease both in patients with SSc-ILD who were and were not using mycophenolate at baseline, with no heterogeneity in its treatment effect detected between the subgroups. The adverse event profile of nintedanib was similar in the subgroups by mycophenolate use. Our findings suggest that the combination of mycophenolate and nintedanib offers a safe treatment option for patients with SSc-ILD. More data are needed on the benefits of initial combination therapy versus a sequential approach to treatment of SSc-ILD. FUNDING Boehringer Ingelheim.

Abstract
Idiopathic pulmonary fibrosis (IPF), a progressive disorder of unknown etiology, is characterized by pathological lung fibroblast activation and proliferation resulting in abnormal deposition of extracellular matrix proteins within the lung parenchyma. The pathophysiological roles of exosomal microRNAs in pulmonary fibrosis remain unclear; therefore, we aimed to identify and characterize fibrosis-responsive exosomal microRNAs. We used microRNA array analysis and profiled the expression of exosome-derived miRNA in sera of C57BL/6 mice exhibiting bleomycin-induced pulmonary fibrosis. The effect of microRNAs potentially involved in fibrosis was then evaluated in vivo and in vitro. The expression of exosomal microRNA-16 was increased by up to 8.0-fold on day 14 in bleomycin-treated mice, compared to vehicle-treated mice. MicroRNA-16 mimic administration on day 14 after bleomycin challenge ameliorated pulmonary fibrosis and suppressed lung and serum expression of secreted protein acidic and rich in cysteine (SPARC). Pretreatment of human lung fibroblasts with the microRNA-16 mimic decreased the expression of rapamycin-insensitive companion of mTOR (Rictor) and TGF-β1-induced expression of SPARC. This is the first study reporting the anti-fibrotic properties of microRNA-16 and demonstrating that these effects occur via the mTORC2 pathway. These findings support that microRNA-16 may be a promising therapeutic target for IPF.

Abstract
Background Idiopathic pulmonary fibrosis (IPF) is a progressive, fatal disorder with a variable disease course. The recent advancement of antifibrotic therapy has increased the need for reliable and specific biomarkers. This study aimed to assess alveolar epithelial biomarkers as predictors for the efficacy of the antifibrotic drug pirfenidone. Methods We conducted a post-hoc analysis of the prospective, multicenter, randomized, placebo-controlled, phase 3 trial of pirfenidone in Japan (total, n = 267; pirfenidone, n = 163; placebo, n = 104). Logistic regression analysis was performed to extract parameters that predicted disease progression, defined by a ≥ 10% relative decline in vital capacity (VC) from baseline and/or death, at week 52. For assessment of serum surfactant protein (SP)-D, SP-A and Krebs von den Lungen (KL)-6, all patients were dichotomized by the median concentration of each biomarker at baseline to the high and low biomarker subgroups. Associations of these concentrations were examined with changes in VC at each time point from baseline up to week 52, along with progression-free survival (PFS). Additionally, the effect of pirfenidone treatment on serial longitudinal concentrations of these biomarkers were evaluated. Results In the multivariate logistic regression analysis, body mass index (BMI), %VC and SP-D in the pirfenidone group, and BMI and %VC in the placebo group were indicated as predictors of disease progression. Pirfenidone treatment reduced the decline in VC with statistical significance in the low SP-D and low SP-A subgroups over most of the treatment period, and also prolonged PFS in the low SP-D and low KL-6 subgroups. Furthermore, SP-D levels over time course were reduced in the pirfenidone group from as early as week 8 until the 52-week treatment period compared with the placebo group. Conclusions Serum SP-D was the most consistent biomarker for the efficacy of pirfenidone in the cohort trial of IPF. Serial measurements of SP-D might have a potential for application as a pharmacodynamic biomarker. Trial registration The clinical trial was registered with the Japan Pharmaceutical Information Center (JAPIC) on September 13, 2005 (registration No. JapicCTI-050121; http://Clinicaltrials.jp)

Abstract
BACKGROUND AND OBJECTIVE In the SENSCIS trial in patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD), nintedanib reduced the rate of decline in forced vital capacity (FVC) (mL/year) over 52 weeks by 44% in comparison with placebo, with manageable adverse events in most patients. We analyzed the efficacy and safety of nintedanib in patients of Asian race. METHODS Patients with SSc-ILD were randomized to receive nintedanib or placebo. The outcomes over 52 weeks were analyzed in Asian versus non-Asian patients. RESULTS Of the 288 patients in each treatment group, 62 (21.5%) in the nintedanib group and 81 (28.1%) in the placebo group were Asian; 90.2% of the Asian patients were enrolled in Asian countries. In the placebo group, the rate of FVC decline over 52 weeks was consistent between Asian and non-Asian patients (-99.9 and -90.6 mL/year, respectively). The effect of nintedanib on reducing the rate of FVC decline over 52 weeks was consistent between Asian (difference, 44.3 mL/year [95% CI: -32.8, 121.4]) and non-Asian patients (difference, 39.0 mL/year [95% CI: -5.1, 83.1]) (treatment-by-time-by-subgroup interaction, p = 0.91). Diarrhea was the most frequent adverse event and was reported in similar proportions of Asian and non-Asian patients in the nintedanib group (80.6% and 74.3%, respectively) and placebo group (28.4% and 32.9%, respectively). CONCLUSIONS In patients with SSc-ILD, nintedanib had a consistent benefit on slowing the progression of SSc-ILD in Asian and non-Asian patients, with a similar adverse event profile.

Abstract
We experienced a rare case of tubulointerstitial angiocentric granulomatous vasculitis with focal segmental glomerulosclerosis (FSGS) and associated sarcoidosis. Our patient was an 18-year-old man who presented with exertional cough and dyspnea. He also had overt proteinuria (3.0 g/24 h), normal renal function (eGFR 95 mL/min/1.73 m<sup>2</sup>), heart failure, and hypertension. He had no previous episode of hypertension. These manifestations immediately improved after the administration of antihypertensive therapy that contained an angiotensin-converting enzyme inhibitor, calcium antagonists, beta antagonists, and diuretics. However, he, later on, developed renal dysfunction, with worsening of both proteinuria and hypertension. Renal biopsy was performed and showed epithelioid cells that were arranged concentrically around small blood vessels in tubulointerstitial granulomas. In the glomeruli, the segmental sclerotic lesions were classified as a perihilar variant of FSGS. There were no inflammatory changes, such as a mesangial lesion, inflammatory cell infiltration, fibrinoid necrosis, or crescent formation, and no glomerular granuloma. In the tubulointerstitial granulomas, the intimal elastic lamina of the interlobular arteries was reduplicated, and the intimal wall thickness of renal arterioles was remarkable. After receiving oral prednisolone therapy, the overt proteinuria resolved, the eGFR recovered from 39.4 to 60.6 mL/min/1.73 m<sup>2</sup>, and hypertension was managed more easily. Thereafter, he did not experience any recurrence. The concurrent improvement of renal function and proteinuria by steroid treatment suggested a relationship between the glomerular lesions and the tubulointerstitial granulomatous vasculitis with associated sarcoidosis.

Abstract
OBJECTIVES To characterise the safety and tolerability of nintedanib and the dose adjustments used to manage adverse events in patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD). METHODS In the SENSCIS trial, patients with SSc-ILD were randomised to receive nintedanib 150 mg two times per day or placebo. To manage adverse events, treatment could be interrupted or the dose reduced to 100 mg two times per day. We assessed adverse events and dose adjustments over 52 weeks. RESULTS A total of 576 patients received nintedanib (n=288) or placebo (n=288). The most common adverse event was diarrhoea, reported in 75.7% of patients in the nintedanib group and 31.6% in the placebo group; diarrhoea led to permanent treatment discontinuation in 6.9% and 0.3% of patients in the nintedanib and placebo groups, respectively. In the nintedanib and placebo groups, respectively, 48.3% and 12.2% of patients had ≥1 dose reduction and/or treatment interruption, and adverse events led to permanent discontinuation of the trial drug in 16.0% and 8.7% of patients. The adverse events associated with nintedanib were similar across subgroups defined by age, sex, race and weight. The rate of decline in forced vital capacity in patients treated with nintedanib was similar irrespective of dose adjustments. CONCLUSIONS The adverse event profile of nintedanib in patients with SSc-ILD is consistent with its established safety and tolerability profile in patients with idiopathic pulmonary fibrosis. Dose adjustment is important to minimise the impact of adverse events and help patients remain on therapy.

Abstract
Background Chemotherapy-induced acute exacerbation (AEx) of idiopathic interstitial pneumonias (IIPs) seriously compromises the success of treatment of Japanese lung cancer patients. Here, we conducted a nationwide surveillance to clarify the risk of AEx and compare it with the survival benefit of chemotherapy for this population. Methods Advanced nonsmall cell lung cancer (NSCLC) or small cell lung cancer (SCLC) patients with IIPs were retrospectively analysed. For the surveillance of first-line chemotherapy in 2009, we gathered clinical data from 396 patients who received chemotherapy at 19 institutions between January 1990 and July 2009. In a consecutive retrospective study in 2012, we analysed data from 278 patients from 17 institutions who received second-line chemotherapy between April 2002 and March 2012. Results Of the 396 patients analysed, 13.1% developed chemotherapy-related AEx. Combination chemotherapies of carboplatin plus paclitaxel (CP) or carboplatin plus etoposide (CE) were frequently used as first-line treatments. The lowest incidence of AEx was 3.7% in CE, followed by 8.6% in CP. In the retrospective study, 16.2% of the 278 patients developed a second-line chemotherapy-related AEx. The overall response rate by second-line chemotherapy was 7.4% in NSCLC and 25.7% in SCLC. The median overall survival from second-line and first-line chemotherapy was 8.0 and 14.3 months in NSCLC, and 8.7 and 16.0 months in SCLC, respectively. Conclusion Combination chemotherapies consisting of CP or CE are candidates for standard first-line treatments for patients with advanced lung cancer accompanied by IIP. Second-line chemotherapy should be considered for patients remaining fit enough to receive it. The Japanese are at high risk of acute exacerbation of IPF. Therefore, chemotherapy for Japanese lung cancer patients with IIPs is challenging. However, appropriate chemotherapy may give a survival benefit, despite the risk of acute deterioration of IIPs.http://bit.ly/3cROaCy

Abstract
The disease concept of interstitial lung disease with idiopathic pulmonary fibrosis at its core has been relied on for many years depending on morphological classification. The separation of non-specific interstitial pneumonia with a relatively good prognosis from usual interstitial pneumonia is also based on the perception that morphology enables predict the prognosis. Beginning with dust-exposed lungs, initially, interstitial pneumonia is classified by anatomical pathology. Diagnostic imaging has dramatically improved the diagnostic technology for surviving patients through the introduction of high-resolution computed tomography scan. And now, with the introduction of therapeutics, the direction of diagnosis is turning. It can be broadly classified into to make known the importance of early diagnosis, and to understand the importance of predicting the speed of progression/deterioration of pathological conditions. For this reason, the insight of “early lesions” has been discussed. There are reports that the presence or absence of interstitial lung abnormalities affects the prognosis. Searching for a biomarker is another prognostic indicator search. However, as is the case with many chronic diseases, pathological conditions that progress linearly are extremely rare. Rather, it progresses while changing in response to environmental factors. In interstitial lung disease, deterioration of respiratory functions most closely reflect prognosis. Treatment is determined by combining dynamic indicators as faithful indicators of restrictive impairments. Reconsidering the history being classified under the disease concept, the need to reorganize treatment targets based on common pathological phenotype is under discussed. What is the disease concept? That aspect changes with the discussion of improving prognosis.

Abstract
OBJECTIVE We examined the efficacy and safety of nintedanib in Japanese patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD) in the global Safety and Efficacy of Nintedanib in Systemic Sclerosis (SENSCIS) trial. METHODS Randomised patients received oral nintedanib 150 mg (N = 34) twice daily or placebo (N = 36) until the last patient reached 52 weeks of treatment (up to 100 weeks). Data were analysed using a subgroup analysis model with Japanese and non-Japanese patients as subgroup variables. RESULTS In Japanese patients, the adjusted annual rate of forced vital capacity (FVC) decline over 52 weeks was -86.2 mL/year (nintedanib) and -90.9 mL/year (placebo); treatment difference, 4.67 mL/year (95% confidence interval, -103.28, 112.63). Treatment effect heterogeneity between Japanese and non-Japanese patients was not detected (treatment-by-visit-by-subgroup interaction; p = .49). FVC decline was smaller for nintedanib versus placebo through 100 weeks in Japanese patients. The most commonly reported adverse events with nintedanib were gastrointestinal and liver disorder events; most were mild-to-moderate in severity. CONCLUSION In both Japanese and non-Japanese patients with SSc-ILD, nintedanib slowed the progression of ILD, with no heterogeneity detected between the subgroups. The safety profile for nintedanib in Japanese patients was similar to that observed in patients with idiopathic pulmonary fibrosis (ClinicalTrials.gov: NCT02597933).

Abstract
Nintedanib (Ofev™), an oral triple kinase inhibitor targeting pro-fibrotic pathways, has been used for treatment of idiopathic pulmonary fibrosis (IPF). Based on positive results from phase III, placebo-controlled, randomized comparative clinical trial conducted in patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD), nintedanib received marketing approval in the United States and Japan for the treatment of SSc-ILD. Nintedanib significantly reduced the annual rate of decline in forced vital capacity over 52 weeks compared with placebo. The safety profiles observed in this trial were consistent with those reported in IPF patients, and the most common adverse events were gastrointestinal disorders, including diarrhea, nausea, and vomiting, which sometimes lead to discontinuation or permanent dose reduction of nintedanib. In contrast, serious adverse events were infrequent and were related mostly to worsening of cardiopulmonary involvement of SSc. This review summarizes the milestones in development of nintedanib leading to the approval for the treatment of SSc-ILD, and covers mechanisms of action, efficacy results and safety profiles, and future perspectives of nintedanib.

Abstract
We report a case of pneumonitis with alveolar hemorrhage induced by herbal medicines in a 73-year-old woman who was admitted to our hospital because of dyspnea and an abnormal shadow on a chest radiograph. She had received treatment with numerous drugs, including the herbal medicines Seisin-renshi-in, Chotosan, Rikkunshi-to, and Shakuyakukannzo-to. Chest radiography revealed diffuse ground-glass shadows in both lungs, and bronchoalveolar lavage fluid was progressively hemorrhagic. A culture of the fluid showed no evidence of microorganisms. Moreover, there were no findings suggestive of rheumatic disease or vasculitides. On the basis of this evidence, we suspected drug-induced diffuse alveolar hemorrhage. She discontinued all medicines and started treatment with corticosteroids. Her respiratory condition and chest radiographic findings improved. The timing of administration and rechallenge with other drugs suggested that the herbal medicines were the causative drugs. The primary concern was Seisin-renshi-in, because it contains Ougon (skullcap; a known cause of pneumonitis) and because a drug lymphocyte stimulation test was positive for Seisin-renshi-in. This is the first report indicating that Seisin-renshi-in may cause diffuse alveolar hemorrhage. Diffuse alveolar hemorrhage due to herbal medicines is a rare but emergent disorder. Therefore, treating physicians should be aware that it may be caused by herbal medicines, including Seisin-renshi-in.

Abstract
BACKGROUND Although aberrant proliferation and activation of lung fibroblasts are implicated in the initiation and progression of idiopathic pulmonary fibrosis (IPF), the underlying mechanisms are not well characterized. Numerous microRNAs (miRNAs) have been implicated in this process; however, miRNAs derived from exosomes and the relevance of such miRNAs to fibroblast-to-myofibroblast differentiation are not well understood. In this study, we attempted to identify exosome-derived miRNAs relevant to fibrosis development. METHODS Using miRNA array analysis, we profiled exosome-derived miRNA expression in sera of C57BL/6 mice exhibiting bleomycin-induced pulmonary fibrosis. After validating a selected miRNA by quantitative reverse-transcription polymerase chain reaction, its effect on fibroblast-to-myofibroblast differentiation was investigated in human lung fibroblasts. Furthermore, we determined the role of the selected miRNA in an in vivo model of pulmonary fibrosis. RESULTS MiRNA array analysis revealed that miR-22 expression was increased by up to 2 fold on day 7 after bleomycin treatment compared with that in vehicle-treated mice. In vitro, miR-22 transfection suppressed TGF-β1-induced α-SMA expression. This was mediated via inhibition of the ERK1/2 pathway. Baseline α-SMA expression was increased upon miR-22 inhibitor transfection. Furthermore, miR-22 negatively regulated connective tissue growth factor expression in the presence of TGF-β1. In vivo, administration of a miR-22 mimic on day 10 after bleomycin challenge ameliorated pulmonary fibrosis lesions accompanied by decreased α-SMA expression in the model mice. CONCLUSIONS Exosomal miR-22 modulates fibroblast-to-myofibroblast differentiation. The present findings warrant further study, which could shed light on miR-22 as a novel therapeutic target in IPF.

Abstract
BACKGROUND Diffuse panbronchiolitis (DPB) is a sinopulmonary disease mainly affecting Asian populations. Primary ciliary dyskinesia (PCD) is a genetically heterogeneous disorder impairing ciliary structure and function. These two disorders are not easily distinguished by clinical signs and symptoms. METHODS In 105 Japanese patients with recurrent sinopulmonary infection, initially diagnosed with DPB, and 37 patients with recurrent airway infection diagnosed in adulthood, the deletion allele of DRC1 or CCDC164, recently recognized as a pathogenic PCD gene variant, was searched using a multiplexed PCR-based method, and the deletion breakpoints and other variants around the gene were determined by Sanger sequencing and targeted resequencing. RESULTS A large homozygous deletion in DRC1 was identified in three of the 142 patients. Furthermore, heterozygous carriers of the deletion with the same breakpoint were found with the allele frequency of 0.002 in the healthy Japanese population, indicating that this loss-of-function variant may be acting as a common mutation causing PCD in Japanese. CONCLUSION PCD caused by the DRC1 defect is not readily identified by either high-speed video-microscopy or ciliary ultrastructure analysis, posing significant difficulties in reaching a correct diagnosis without the aid of genetic tests. Careful investigation of the causes of sinopulmonary diseases is warranted in Asian populations.

Abstract
BACKGROUND This document provides clinical recommendations for the diagnosis of idiopathic pulmonary fibrosis (IPF). It represents a collaborative effort between the American Thoracic Society, European Respiratory Society, Japanese Respiratory Society, and Latin American Thoracic Society. METHODS The evidence syntheses were discussed and recommendations formulated by a multidisciplinary committee of IPF experts. The evidence was appraised and recommendations were formulated, written, and graded using the Grading of Recommendations, Assessment, Development, and Evaluation approach. RESULTS The guideline panel updated the diagnostic criteria for IPF. Previously defined patterns of usual interstitial pneumonia (UIP) were refined to patterns of UIP, probable UIP, indeterminate, and alternate diagnosis. For patients with newly detected interstitial lung disease (ILD) who have a high-resolution computed tomography scan pattern of probable UIP, indeterminate, or an alternative diagnosis, conditional recommendations were made for performing BAL and surgical lung biopsy; because of lack of evidence, no recommendation was made for or against performing transbronchial lung biopsy or lung cryobiopsy. In contrast, for patients with newly detected ILD who have a high-resolution computed tomography scan pattern of UIP, strong recommendations were made against performing surgical lung biopsy, transbronchial lung biopsy, and lung cryobiopsy, and a conditional recommendation was made against performing BAL. Additional recommendations included a conditional recommendation for multidisciplinary discussion and a strong recommendation against measurement of serum biomarkers for the sole purpose of distinguishing IPF from other ILDs. CONCLUSIONS The guideline panel provided recommendations related to the diagnosis of IPF.
