RESUMO
Background: Interstitial lung disease (ILD) is a significant cause of morbidity and mortality in patients with systemic sclerosis (SSc). To date, clinical practice guidelines regarding treatment for patients with SSc-ILD are primarily consensus based. Methods: An international expert guideline committee composed of 24 individuals with expertise in rheumatology, SSc, pulmonology, ILD, or methodology, and with personal experience with SSc-ILD, discussed systematic reviews of the published evidence assessed using the Grading of Recommendations, Assessment, Development, and Evaluation approach. Predetermined conflict-of-interest management strategies were applied, and recommendations were made for or against specific treatment interventions exclusively by the nonconflicted panelists. The confidence in effect estimates, importance of outcomes studied, balance of desirable and undesirable consequences of treatment, cost, feasibility, acceptability of the intervention, and implications for health equity were all considered in making the recommendations. This was in accordance with the American Thoracic Society guideline development process, which is in compliance with the Institute of Medicine standards for trustworthy guidelines. Results: For treatment of patients with SSc-ILD, the committee: 1) recommends the use of mycophenolate; 2) recommends further research into the safety and efficacy of (a) pirfenidone and (b) the combination of pirfenidone plus mycophenolate; and 3) suggests the use of (a) cyclophosphamide, (b) rituximab, (c) tocilizumab, (d) nintedanib, and (e) the combination of nintedanib plus mycophenolate. Conclusions: The recommendations herein provide an evidence-based clinical practice guideline for the treatment of patients with SSc-ILD and are intended to serve as the basis for informed and shared decision making by clinicians and patients.

Background: Idiopathic pulmonary fibrosis (IPF) carries significant mortality and unpredictable progression, with limited therapeutic options. Designing trials with patient-meaningful endpoints, enhancing the reliability and interpretability of results, and streamlining the regulatory approval process are of critical importance to advancing clinical care in IPF. Methods: A landmark in-person symposium in June 2023 assembled 43 participants from the US and internationally, including patients with IPF, investigators, and regulatory representatives, to discuss the immediate future of IPF clinical trial endpoints. Patient advocates were central to discussions, which evaluated endpoints according to regulatory standards and the FDA's 'feels, functions, survives' criteria. Results: Three themes emerged: 1) consensus on endpoints mirroring the lived experiences of patients with IPF; 2) consideration of replacing forced vital capacity (FVC) as the primary endpoint, potentially by composite endpoints that include 'feels, functions, survives' measures or FVC as components; 3) support for simplified, user-friendly patient-reported outcomes (PROs) as either components of primary composite endpoints or key secondary endpoints, supplemented by functional tests as secondary endpoints and novel biomarkers as supportive measures (FDA Guidance for Industry (Multiple Endpoints in Clinical Trials) available at: https://www.fda.gov/media/162416/download). Conclusions: This report, detailing the proceedings of this pivotal symposium, suggests a potential turning point in designing future IPF clinical trials more attuned to outcomes meaningful to patients, and documents the collective agreement across multidisciplinary stakeholders on the importance of anchoring IPF trial endpoints on real patient experiences-namely, how they feel, function, and survive. There is considerable optimism that clinical care in IPF will progress through trials focused on patient-centric insights, ultimately guiding transformative treatment strategies to enhance patients' quality of life and survival.

Background: This American Thoracic Society, European Respiratory Society, Japanese Respiratory Society, and Asociación Latinoamericana de Tórax guideline updates prior idiopathic pulmonary fibrosis (IPF) guidelines and addresses the progression of pulmonary fibrosis in patients with interstitial lung diseases (ILDs) other than IPF. Methods: A committee was composed of multidisciplinary experts in ILD, methodologists, and patient representatives. 1) Update of IPF: Radiological and histopathological criteria for IPF were updated by consensus. Questions about transbronchial lung cryobiopsy, genomic classifier testing, antacid medication, and antireflux surgery were informed by systematic reviews and answered with evidence-based recommendations using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. 2) Progressive pulmonary fibrosis (PPF): PPF was defined, and then radiological and physiological criteria for PPF were determined by consensus. Questions about pirfenidone and nintedanib were informed by systematic reviews and answered with evidence-based recommendations using the GRADE approach. Results:1) Update of IPF: A conditional recommendation was made to regard transbronchial lung cryobiopsy as an acceptable alternative to surgical lung biopsy in centers with appropriate expertise. No recommendation was made for or against genomic classifier testing. Conditional recommendations were made against antacid medication and antireflux surgery for the treatment of IPF. 2) PPF: PPF was defined as at least two of three criteria (worsening symptoms, radiological progression, and physiological progression) occurring within the past year with no alternative explanation in a patient with an ILD other than IPF. A conditional recommendation was made for nintedanib, and additional research into pirfenidone was recommended. Conclusions: The conditional recommendations in this guideline are intended to provide the basis for rational, informed decisions by clinicians.

Background: Evidence-based guidelines are needed for effective delivery of home oxygen therapy to appropriate patients with chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD).Methods: The multidisciplinary panel created six research questions using a modified Delphi approach. A systematic review of the literature was completed, and the Grading of Recommendations Assessment, Development and Evaluation approach was used to formulate clinical recommendations.Recommendations: The panel found varying quality and availability of evidence and made the following judgments: 1) strong recommendations for long-term oxygen use in patients with COPD (moderate-quality evidence) or ILD (low-quality evidence) with severe chronic resting hypoxemia, 2) a conditional recommendation against long-term oxygen use in patients with COPD with moderate chronic resting hypoxemia, 3) conditional recommendations for ambulatory oxygen use in patients with COPD (moderate-quality evidence) or ILD (low-quality evidence) with severe exertional hypoxemia, 4) a conditional recommendation for ambulatory liquid-oxygen use in patients who are mobile outside the home and require >3 L/min of continuous-flow oxygen during exertion (very-low-quality evidence), and 5) a recommendation that patients and their caregivers receive education on oxygen equipment and safety (best-practice statement).Conclusions: These guidelines provide the basis for evidence-based use of home oxygen therapy in adults with COPD or ILD but also highlight the need for additional research to guide clinical practice.

Network meta-analysis is an extension of the conventional pair wise meta-analysis to include treatments that have not been compared head to head. It has in recent years caught the interest of clinical investigators in comparative effectiveness research. While allowing a simultaneous comparison of a large number of treatment effects, an inclusion of indirect effects (i.e., estimating effects using treatments that have not been randomized head to head) may introduce bias. This bias occurs from not accounting for covariates differences in the analysis, in a way that allows transfer of causal information across trials. Although this problem might not be entirely new to network meta-analysis researchers, it has not been given a formal treatment. Occasionally it is tackled by fitting a meta-regression model to account for imbalance of covariates. However, this approach may still produce biased estimates if covariates responsible for disparity across studies are post-treatment variables. To address the problem, we use the graphical method known as transportability to demonstrate whether and how indirect treatment effects can validly be estimated in network meta-analysis.

Pulmonary hypertension (PH) can occur in patients with obstructive sleep apnea (OSA) in the absence of cardiac or lung disease. Data on the development and severity of PH, and the effect of continuous positive airway pressure (CPAP) therapy on pulmonary artery (PA) pressures in these patients have been inconsistent in the literature. We sought to determine whether CPAP therapy affects PA pressures in patients with isolated OSA in this meta-analysis. We searched PubMed, Medline, EMBASE and other databases from January 1980 to August 2015. Studies of patients with OSA, defined as an apnea-hypopnea index >10 events/h, and PH, defined as PA pressure >25 mmHg were included. Two reviewers independently extracted data and assessed risk of bias. A total of 222 patients from seven studies (341.53 person-years) had reported PA pressures before and after treatment with CPAP therapy. 77 % of participants were men, with a mean age of 52.5 years, a mean apnea-hypopnea index of 58 events/h, and mean PA pressure of 39.3 ± 6.3 mmHg. CPAP treatment duration ranged from 3 to 70 months. Using fixed effects meta-analysis, CPAP therapy was associated with a decrease in PA pressure of 13.3 mmHg (95 % CI 12.7-14.0) in our study population. This meta-analysis found that CPAP therapy is associated with a significantly lower PA pressure in patients with isolated OSA and PH.

Rationale: The American Thoracic Society convened an international, multidisciplinary panel to develop clinical practice guidelines for the treatment of systemic sclerosis-associated interstitial lung disease (SSc-ILD). Objective: To conduct a systematic review and evaluate the literature to determine whether patients with SSc-ILD should be treated with mycophenolate. Methods: A literature search was conducted across the MEDLINE, EMBASE, and CENTRAL databases through June 2022 for studies using mycophenolate to treat patients with SSc-ILD. Mortality, disease progression, quality of life, and adverse event data were extracted, and meta-analyses were performed when possible. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) Working Group method was used to assess the quality of evidence. Results: The literature review resulted in seven studies fitting the inclusion criteria. The systematic review and meta-analyses revealed changes in forced vital capacity % predicted (mean difference [MD], 5.4%; 95% confidence interval [95% CI]: 3.3%, 7.5%), diffusing capacity of the lung for carbon monoxide % predicted (MD, 4.64%; 95% CI: 0.54%, 8.74%), and breathlessness score (MD, 1.99; 95% CI: 0.36, 3.62) favored mycophenolate over placebo. The risk of anemia (relative risk [RR], 2.3; 95% CI: 1.2, 71.4) was higher with mycophenolate. There were no significant differences between mycophenolate and cyclophosphamide, except risk of premature discontinuation (RR, 0.6; 95% CI: 0.4, 0.9), and leukopenia (RR, 0.1; 95% CI: 0.05, 0.4) favored mycophenolate. The quality of evidence was moderate to very low per GRADE. Conclusions: Mycophenolate use in patients with SSc-ILD is associated with statistically significant improvements in disease progression and quality-of-life measures compared with placebo. There were no differences in mortality, disease progression, or quality of life compared with cyclophosphamide, but there were fewer adverse events. The quality of evidence is very low.

Background: The American Thoracic Society convened an international, multidisciplinary panel to develop clinical practice guidelines for the treatment of systemic sclerosis-associated interstitial lung disease (SSc-ILD). Objective: To conduct a systematic review and evaluate the literature to determine whether patients with SSc-ILD should be treated with cyclophosphamide. Data Sources: A literature search was conducted across the MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials databases through June 2022 for studies using cyclophosphamide to treat patients with SSc-ILD. Data Extraction: Mortality, disease progression, quality of life, and adverse event data were extracted, and meta-analyses were performed when possible. The Grading of Recommendations, Assessment, Development and Evaluation Working Group method was used to assess the quality of evidence. Synthesis: Five studies were included; two randomized controlled trials compared cyclophosphamide versus placebo, and one randomized controlled trial and two retrospective case-control studies compared cyclophosphamide versus mycophenolate. Compared with placebo, there was a 2.83% reduction in the decline at 12 months for forced vital capacity (FVC) % predicted using cyclophosphamide (95% confidence interval [CI], 0.80-4.87; low evidence). There were improvements in breathlessness (Transition Dyspnea Index mean difference [MD], 2.90; 95% CI, 1.94-3.86; minimum clinically important difference, 1; moderate evidence) and disability (Health Assessment Questionnaire-Disability Index MD, -0.16; 95% CI, -0.28 to -0.04; minimum clinically important difference, -0.14; moderate evidence). There were increased risks of leukopenia and constitutional symptoms using cyclophosphamide, but no difference in mortality. When cyclophosphamide was compared with mycophenolate, there were differences in diffusing capacity of the lung for carbon monoxide % predicted favoring mycophenolate at 6 months (MD, -3.67%; 95% CI, -6.3% to -1.1% unadjusted; MD, -4.88%; 95% CI, -7.3% to -2.5% adjusted for alveolar volume; moderate evidence), 12 months (MD, -5.90%; 95% CI, -8.4% to -3.4% adjusted for alveolar volume; moderate evidence), and 18 months (MD, -3.26%; 95% CI, -6.1% to -0.4%; moderate evidence), but not at 24 months. There were no differences in FVC % predicted, mortality, or quality-of-life outcomes, but participants were more likely to prematurely discontinue cyclophosphamide compared with mycophenolate (relative risk, 1.70; 95% CI, 1.10-2.63; high-certainty evidence). Conclusions: A review of the published evidence shows that cyclophosphamide is effective in SSc-ILD compared with placebo, with an increased risk of side effects. However, mycophenolate may be equivocal or better than cyclophosphamide. Clinicians and patients should weigh the potential benefits and risks with respect to individual patient circumstances and preferences.

Background: The American Thoracic Society convened an international, multidisciplinary panel to develop clinical practice guidelines for the treatment of systemic sclerosis-associated interstitial lung disease (SSc-ILD). Objective: To conduct a systematic review and evaluate the literature to determine whether patients with SSc-ILD should be treated with rituximab. Data Sources: A literature search was conducted across MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) databases through June 2022 for studies using rituximab to treat patients with SSc-ILD. Data Extraction: Disease progression, quality of life, mortality, and adverse event data were extracted. The intervention was rituximab. The standard-of-care comparator group was decided a priori by consensus of the panel as either placebo or mycophenolate. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) Working Group approach was used to assess the quality of evidence. Synthesis: Three relevant studies were selected. Rituximab significantly improved the forced vital capacity % predicted (mean difference, 3.13; 95% confidence interval [CI], 0.37 to 5.90) and the modified Rodnan Skin Score (mean difference, -7.01; 95% CI, 11.46 to -2.56) at 24-48 weeks. Conclusions: Rituximab use in patients with SSc-ILD is associated with stabilization of lung function. The quality of evidence for study outcomes was considered to be very low, as defined by the GRADE approach. Additional research on treatment with rituximab is imperative.

Background: The American Thoracic Society convened an international multidisciplinary panel to develop clinical practice guidelines for the treatment of systemic sclerosis-associated interstitial lung disease (SSc-ILD). Objective: To conduct a systematic review and evaluate the literature to determine whether patients with SSc-ILD should be treated with nintedanib alone or with the combination of nintedanib plus mycophenolate. Data Sources: Literature searches were conducted across MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials databases through June 2022 for studies using nintedanib or nintedanib plus mycophenolate to treat patients with SSc-ILD. Data Extraction: Mortality, disease progression, quality of life, and adverse event data were extracted, and meta-analysis was performed when possible. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) Working Group method was used to assess the quality of evidence. Synthesis: For nintedanib therapy alone, the systematic review included three total studies and revealed that disease progression was less in the nintedanib arm (the annual rate of decline in forced vital capacity [FVC] was 44.5 ml less, the absolute change from baseline was 46.4 ml less, and FVC% predicted was 1.2% less in the nintedanib arm) compared with placebo. However, gastrointestinal side effects and treatment discontinuation were double in the nintedanib arm compared with placebo. For combination therapy, the systematic review also included three total studies and revealed that changes in the annual rate of decline in FVC favored combination therapy over placebo (mean difference, 79.1 ml). Combination therapy was, however, associated with increased gastrointestinal adverse effects compared with placebo. The quality of evidence for all outcomes was very low as per GRADE. Conclusions: The use of nintedanib alone and in combination with mycophenolate in patients with SSc-ILD is associated with a significant reduction in disease progression compared with placebo but at the cost of increased gastrointestinal side effects and treatment discontinuation. The quality of evidence is very low.

Background: The American Thoracic Society (ATS) convened an international, multidisciplinary panel to develop clinical practice guidelines for the treatment of systemic sclerosis-associated interstitial lung disease (SSc-ILD). Objective: To conduct a systematic review and evaluate the literature to determine the impact of treating patients with SSc-ILD with tocilizumab on prespecified critical and important outcomes determined by the ATS guideline panel. Data Sources: A literature search was conducted across MEDLINE, EMBASE, and Cochrane databases through June 2022 for studies using tocilizumab to treat patients with SSc-ILD. Data Extraction: Mortality and disease progression were determined to be critical outcomes of focus, with quality of life and adverse events important outcomes. Data on these outcomes were extracted and meta-analyses performed using the generic inverse variance method when possible. The Grading of Recommendations, Assessment, Development, and Evaluation Working Group method was used to assess the quality of evidence. Synthesis: The literature review resulted in five studies for inclusion. The absolute decrease from baseline in forced vital capacity (FVC) for the tocilizumab arm was 118 ml, 241 ml, and 129 ml less than the placebo arm at 24, 48, and 96 weeks, respectively, favoring tocilizumab. The mean decrease in FVC% predicted at 48 weeks was 6.50% less and the risk of decrease >10% was 66% less in the tocilizumab arm, whereas patients were 1.97 times more likely to have any increase in FVC% predicted if they received tocilizumab in place of placebo. When the placebo arm was given tocilizumab from 48 to 96 weeks, the mean change in absolute FVC was 54.90 ml less and the mean change in FVC% predicted was 1.30% less. For diffusing capacity of the lung for carbon monoxide (DlCO)% predicted, at 48 weeks there was 1.50% less change and from 48 to 96 weeks there was 5.40% less change in the tocilizumab arm. Quantitative Interstitial Lung Disease scores and Quantitative Lung Fibrosis scores at 48 weeks and modified Rodnan skin scores at 72 weeks all favored the tocilizumab arm, as did several adverse event parameters, including serious adverse events (mean difference, -27.40; 95% confidence interval, -30.10 to -24.70). The quality of evidence was very low grade. Conclusions: Tocilizumab use in patients with SSc-ILD is associated with less disease progression and a better toxicity profile than placebo. However, the quality of evidence is very low, and large prospective studies dedicated to assessing tocilizumab specifically for SSc-ILD are needed.

BACKGROUND: Compared with White patients, Black and Latinx patients have higher infection, hospitalization, and mortality rates from COVID-19; yet, little is known about their perspective before, during, and after a COVID-19 hospitalization. The objective of this study conducted in White, Black, and Latinx patients was to assess perceptions of their COVID-19-related hospitalization from onset of symptoms through the post-discharge period to identify disparities in their perceived care. METHODS: A cross-sectional observational study using an online survey from May 19 to June 23, 2021, was conducted by The Harris Poll in 200 White, 200 Black, and 201 Latinx patients hospitalized for COVID-19 in the US. Main measures obtained included baseline demographic variables, socioeconomic status, and social determinants of health. Survey questions were specific to key aspects of the patient experience before, during, and after a COVID-19-related hospitalization. RESULTS: Compared with White patients, Latinx and Black patients faced unique challenges in their healthcare journey including higher likelihood of delaying their hospitalization (10% Black vs. 4% White patients, respectively, P = 0.025), lower perceived satisfaction with care (82% Latinx vs 91% White patients, P = 0.002), and lower trust in providers following their hospitalization (85% White vs. 65% Latinx [P = 0.027] and 73% Black [P = 0.050] patients). CONCLUSIONS: Patient perceptions of their COVID-19 hospitalization experience revealed disparities in perceived quality of care among minority groups. These findings offer insights that health inequities still exist, and strategies need to be taken to make health care delivery more equitable.

BACKGROUND: The COVID-19 pandemic has led to unprecedented mental health disturbances, burnout, and moral distress among health care workers, affecting their ability to care for themselves and their patients. RESEARCH QUESTION: In health care workers, what are key systemic factors and interventions impacting mental health and burnout? STUDY DESIGN AND METHODS: The Workforce Sustainment subcommittee of the Task Force for Mass Critical Care (TFMCC) utilized a consensus development process, incorporating evidence from literature review with expert opinion through a modified Delphi approach to determine factors affecting mental health, burnout, and moral distress in health care workers, to propose necessary actions to help prevent these issues and enhance workforce resilience, sustainment, and retention. RESULTS: Consolidation of evidence gathered from literature review and expert opinion resulted in 197 total statements that were synthesized into 14 major suggestions. These suggestions were organized into three categories: (1) mental health and well-being for staff in medical settings; (2) system-level support and leadership; and (3) research priorities and gaps. Suggestions include both general and specific occupational interventions to support health care worker basic physical needs, lower psychological distress, reduce moral distress and burnout, and foster mental health and resilience. INTERPRETATION: The Workforce Sustainment subcommittee of the TFMCC offers evidence-informed operational strategies to assist health care workers and hospitals plan, prevent, and treat the factors affecting health care worker mental health, burnout, and moral distress to improve resilience and retention following the COVID-19 pandemic.

Air pollution poses a serious threat to children's respiratory health around the world. Satellite remote-sensing technology and air quality models can provide pollution data on a global scale, necessary for risk communication efforts in regions without ground-based monitoring networks. Several large centers, including NASA, produce global pollution forecasts that may be used alongside air quality indices to communicate local, daily risk information to the public. Here we present a health-based, globally applicable air quality index developed specifically to reflect the respiratory health risks among children exposed to elevated outdoor air pollution. Additive, excess-risk air quality indices were developed using 51 different coefficients derived from time-series health studies evaluating the impacts of ambient fine particulate matter, nitrogen dioxide, and ozone on children's respiratory morbidity outcomes. A total of four indices were created which varied based on whether or not the underlying studies controlled for co-pollutants and in the adjustment of excess risks of individual pollutants. Combined with historical estimates of air pollution provided globally at a 25 × 25 km2 spatial resolution from the NASA's Goddard Earth Observing System composition forecast (GEOS-CF) model, each of these indices were examined in a global sample of 664 small and 140 large cities for study year 2017. Adjusted indices presented the most normal distributions of locally-scaled index values, which has been shown to improve associations with health risks, while indices based on coefficients controlling for co-pollutants had little effect on index performance. We provide the steps and resources need to apply our final adjusted index at the local level using freely-available forecasting data from the GEOS-CF model, which can provide risk communication information for cities around the world to better inform individual behavior modification to best protect children's respiratory health.

BACKGROUND: Greenhouse gas emissions are changing the Earth's climate, most directly by modifying temperatures and temperature variability (TV). Residents of low- and middle-income countries (LMICs) are likely more adversely affected, due to lack of air conditioning to compensate. To date, there is no local epidemiological evidence documenting the cardio-respiratory health effects of TV in Dhaka, Bangladesh, one of the most climate change vulnerable cities in the world. OBJECTIVES: We assessed short-term TV associations with daily cardiovascular disease (CVD) and respiratory emergency department (ED) visits, as well as effect modification by age and season. METHODS: TV was calculated from the standard deviations of the daily minimum and maximum temperatures over exposure days. Time-series regression modeling was applied to daily ED visits for respiratory and CVD from January 2014 through December 2017. TV effect sizes were estimated after controlling for long-term trends and seasonality, day-of-week, holidays, and daily mean relative humidity and ambient temperature. RESULTS: A 1 °C increase in TV was associated with a 1.00% (95 %CI: 0.05%, 1.96%) increase in CVD ED visits at lag 0-1 days (TV0-1) and a 2.77% (95 %CI: 0.24%, 5.20%) increase in respiratory ED visits at lag 0-7 days (TV0-7). TV-CVD associations were larger in the monsoon and cold seasons. Respiratory ED visit associations varied by age, with older adults more affected by the TV across all seasons. A 1 °C increase in TV at lag 0-7 days (TV0-7) was associated with a 7.45% (95 %CI: 2.33%, 12.57%) increase in respiratory ED visits among patients above 50 years of age. CONCLUSION: This study provided novel and important evidence that cardio-pulmonary health in Dhaka is adversely affected year-round by day-to-day increases in TV, especially among older adults. TV is a key factor that should be considered in evaluating the potential human health impacts of climate change induced temperature changes.

A new era in guideline creation began in 2011 with publication of the Institute of Medicine (now the National Academy of Medicine) Standards for Developing Trustworthy Clinical Practice Guidelines. The American Thoracic Society (ATS) was committed to developing guidelines in accordance with the new standards and decided that an experienced guideline methodologist would be required on ATS guideline projects to ensure correct implementation of the standards. The ATS Guideline Methodology Training Program was launched to increase the pool of trained methodologists. Each year, accepted trainees (methodology scholars) attend a workshop that introduces them to the terminology and process of guideline development and are given the option of participating in a guideline project. Scholars work with the mentorship of a lead methodologist to conduct and then present a systematic review to the guideline committee, discuss the evidence, and participate in the development of evidence-based graded recommendations. Scholars have participated in 22 ATS guidelines over the past 9 years, and most remain engaged in guideline development. For the past 2 years, the methodological aspects of all ATS guideline projects were led by graduates of the training program, and several scholars have accepted positions to lead guidelines for other professional societies. Guideline methodology is particularly suitable for clinician educators because the work is clinically oriented, and guidelines confer high academic capital. Those who elect not to continue in guideline development still acquire the skills to perform and publish systematic reviews, as well as to educate trainees in reading and reviewing literature.
RESUMO
Background: The American Thoracic Society, European Respiratory Society, Japanese Respiratory Society, and Asociación Latinoamericana del Tórax convened to update clinical practice guidelines for interstitial lung disease (ILD). Objective: To conduct a systematic review to evaluate existing ILD literature to determine whether patients with progressive pulmonary fibrosis (PPF) should be treated with the antifibrotic pirfenidone. Data Sources: A literature search was conducted across MEDLINE, EMBASE, and Cochrane databases through December 2020 for studies using pirfenidone to treat patients with PPF. Data Extraction: Mortality, disease progression, lung function, and adverse event data were extracted. Meta-analyses were performed when possible. The Grading of Recommendations, Assessment, Development and Evaluation Working Group approach was used to assess the quality of evidence. Synthesis: Two studies met inclusion criteria. Meta-analyses revealed that changes in forced vital capacity (FVC) percent predicted (mean difference [MD], 2.3%; 95% confidence interval [CI], 0.5-4.1%), the FVC in milliliters (MD, 100.0 ml; 95% CI, 98.1-101.9 ml), and the 6-minute-walk distance in meters (MD, 25.2 m; 95% CI, 8.3-42.1 m) all favored pirfenidone over placebo. The changes in the diffusing capacity of the lung for carbon monoxide (DLCO) in millimoles per kilopascal per minute (MD, 0.40 mmol/kPa/min; 95%, CI 0.10-0.70 mmol/kPa/min) and risk of DLCO declining more than 15% (relative risk [RR], 0.27; 95% CI, 0.08-0.95) also favored pirfenidone. The risks of gastrointestinal discomfort (RR, 1.83; 95% CI, 1.29-2.60) and photosensitivity (RR, 4.88; 95% CI, 1.09-21.83) were higher with pirfenidone. The quality of the evidence was low or very low according to the Grading of Recommendations, Assessment, Development and Evaluation criteria, depending on the outcome. Conclusions: Pirfenidone use in patients with PPF is associated with a statistically significant decrease in disease progression and with protection of lung function. However, there is very low certainty in the estimated effects because of limitations in the available evidence.

Background: The American Thoracic Society, European Respiratory Society, Japanese Respiratory Society, and Asociación Latinoamericana del Tórax convened to update clinical practice guidelines for interstitial lung disease (ILD). Objective: To conduct a systematic review to evaluate existing ILD literature to determine whether patients with progressive pulmonary fibrosis (PPF) should be treated with the antifibrotic nintedanib. Data Sources: A literature search was conducted across MEDLINE, EMBASE, and Cochrane databases through December 2020 for studies using nintedanib to treat patients with PPF. Data Extraction: Mortality, disease progression, and adverse event data were extracted, and meta-analyses performed when possible. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) Working Group approach was used to assess the quality of evidence. Synthesis: Two relevant studies were selected. The annual decline in forced vital capacity was less in the nintedanib arm in the overall study population (mean difference [MD], 107 ml/yr; 95% confidence interval [CI], 65.4 to 148.5 ml/yr) and in the subgroups with usual interstitial pneumonia (UIP) pattern of pulmonary fibrosis (MD, 128.2 ml/yr; 95% CI, 70.8 to 185.6 ml/yr), non-UIP patterns of pulmonary fibrosis (MD, 75.3 ml/yr; 95% CI, 15.5 to 135.0 ml/yr), fibrotic connective tissue disease-related ILD (MD, 106.2 ml/yr; 95% CI, 10.6 to 201.9 ml/yr), fibrotic idiopathic nonspecific interstitial pneumonia (MD, 141.7 ml/yr; 95% CI, 46.0 to 237.4 ml/yr), and fibrotic occupational ILD (MD, 252.8 ml/yr; 95% CI, 79.2 to 426.5 ml/yr), but not fibrotic hypersensitivity pneumonitis (MD, 72.9 ml/yr; 95% CI, -8.9 to 154.7 ml/yr), fibrotic sarcoidosis (MD, -20.5 ml/yr; 95% CI, -337.1 to 296.1 ml/yr), or unclassified fibrotic ILD (MD, 68.5 ml/yr; 95% CI, -31.3 to 168.4 ml/yr) when compared with placebo. Gastrointestinal side effects were common. Quality of evidence for the outcomes ranged from very low to moderate GRADE. Conclusions: Nintedanib use in patients with PPF is associated with a statistically significant decrease in disease progression but increase in gastrointestinal side effects regardless of the radiographic pattern of pulmonary fibrosis. However, limitations in the available evidence lead to low certainty in these effect estimates and make definitive conclusions about the differential effects by subtype of ILD difficult to determine.

Background: Usual interstitial pneumonia (UIP) is the histopathologic hallmark of idiopathic pulmonary fibrosis (IPF), the prototypical interstitial lung disease (ILD). Diagnosis of IPF requires that a typical UIP pattern be identified by using high-resolution chest computed tomography or lung sampling. A genomic classifier for UIP has been developed to predict histopathologic UIP by using lung samples obtained through bronchoscopy. Objective: To perform a systematic review to evaluate genomic classifier testing in the detection of histopathologic UIP to inform new American Thoracic Society, European Respiratory Society, Japanese Respiratory Society, and Asociación Latinoamericana del Tórax guidelines. Data Sources: Medline, Embase, and the Cochrane Central Register of Controlled Trials were searched through June 2020. Data Extraction: Data were extracted from studies that enrolled patients with ILD and reported the use of genomic classifier testing. Synthesis: Data were aggregated across studies via meta-analysis. The quality of the evidence was appraised by using the Grading of Recommendations, Assessment, Development, and Evaluation approach. Results: Genomic classifier testing had a sensitivity of 68% (95% confidence interval [CI], 55-73%) and a specificity of 92% (95% CI, 81-95%) in predicting the UIP pattern in ILD. Confidence in an IPF diagnosis increased from 43% to 93% in one cohort and from 59% to 89% in another cohort. Agreement levels in categorical IPF and non-IPF diagnoses measured by using a concordance coefficient were 0.75 and 0.64 in the two cohorts. The quality of evidence was moderate for test characteristics and very low for both confidence and agreement. Conclusions: Genomic classifier testing predicts histopathologic UIP in patients with ILD with a specificity of 92% and improves diagnostic confidence; however, sensitivity is only 68%, and testing is not widely available.

Rationale: In 2018, a systematic review evaluating transbronchial lung cryobiopsy (TBLC) in patients with interstitial lung disease (ILD) was performed to inform American Thoracic Society, European Respiratory Society, Japanese Respiratory Society, and Asociación Latinoamericana del Tórax clinical practice guidelines on the diagnosis of idiopathic pulmonary fibrosis. Objectives: To perform a new systematic review to inform updated guidelines. Methods: Medline, Excerpta Medica Database, and the Cochrane Central Register of Controlled Trials (CCTR) were searched through June 2020. Studies that enrolled patients with ILD and reported the diagnostic yield or complication rates of TBLC were selected for inclusion. Data was extracted and then pooled across studies via meta-analysis. The quality of the evidence was appraised using the grading of recommendations, assessment, development, and evaluation approach. Results: Histopathologic diagnostic yield (number of procedures that yielded a histopathologic diagnosis divided by the total number of procedures performed) of TBLC was 80% (95% confidence interval [CI], 76-83%) in patients with ILD. TBLC was complicated by bleeding and pneumothorax in 30% (95% CI, 20-41%) and 8% (95% CI, 6-11%) of patients, respectively. Procedure-related mortality, severe bleeding, prolonged air leak, acute exacerbation, respiratory failure, and respiratory infection were rare. The quality of the evidence was very low owing to the uncontrolled study designs, lack of consecutive enrollment, and inconsistent results. Conclusions: Very low-quality evidence indicated that TBLC has a diagnostic yield of approximately 80% in patients with ILD, with manageable complications.
