Abstract

BACKGROUND: Smokers manifest varied phenotypes of pulmonary impairment. RESEARCH QUESTION: Which pulmonary phenotypes are associated with coronary artery disease (CAD) in smokers? STUDY DESIGN AND METHODS: We analyzed data from the University of Pittsburgh COPD Specialized Center for Clinically Oriented Research (SCCOR) cohort (n = 481) and the Genetic Epidemiology of COPD (COPDGene) cohort (n = 2,580). Participants were current and former smokers with > 10 pack-years of tobacco exposure. Data from the two cohorts were analyzed separately because of methodologic differences. Lung hyperinflation was assessed by plethysmography in the SCCOR cohort and by inspiratory and expiratory CT scan lung volumes in the COPDGene cohort. Subclinical CAD was assessed as the coronary artery calcium score, whereas clinical CAD was defined as a self-reported history of CAD or myocardial infarction (MI). Analyses were performed in all smokers and then repeated in those with airflow obstruction (FEV(1) to FVC ratio, < 0.70). RESULTS: Pulmonary phenotypes, including airflow limitation, emphysema, lung hyperinflation, diffusion capacity, and radiographic measures of airway remodeling, showed weak to moderate correlations (r < 0.7) with each other. In multivariate models adjusted for pulmonary phenotypes and CAD risk factors, lung hyperinflation was the only phenotype associated with calcium score, history of clinical CAD, or history of MI (per 0.2 higher expiratory and inspiratory CT scan lung volume; coronary calcium: OR, 1.2; 95% CI, 1.1-1.5; P = .02; clinical CAD: OR, 1.6; 95% CI, 1.1-2.3; P = .01; and MI in COPDGene: OR, 1.7; 95% CI, 1.0-2.8; P = .05). FEV(1) and emphysema were associated with increased risk of CAD (P < .05) in models adjusted for CAD risk factors; however, these associations were attenuated on adjusting for lung hyperinflation. Results were the same in those with airflow obstruction and were present in both cohorts. INTERPRETATION: Lung hyperinflation is associated strongly with clinical and subclinical CAD in smokers, including those with airflow obstruction. After lung hyperinflation was accounted for, FEV(1) and emphysema no longer were associated with CAD. Subsequent studies should consider measuring lung hyperinflation and examining its mechanistic role in CAD in current and former smokers.

Abstract

BackgroundBody composition measures, specifically low weight or reduced muscle mass, are associated with mortality in COPD, but the effect of longitudinal body composition changes is undefined.Research questionIs the longitudinal loss of fat-free mass (FFM) associated with increased mortality, including in those with initially normal or elevated body composition metrics?Study design and methodsParticipants with complete data for at least one visit in the COPDGene study (n= 9,268) and the ECLIPSE study (n= 1,760) were included and monitored for 12 and 8 years, respectively. Pectoralis muscle area (PMA) was derived from thoracic CT scans and used as a proxy for FFM. A longitudinal mixed submodel for PMA and a Cox proportional hazards submodel for survival were fitted on a joint distribution, using a shared random intercept parameter and Markov chain Monte Carlo parameter estimation.ResultsBoth cohorts demonstrated a left-shifted distribution of baseline FFM, not reflected in BMI, and an increase in all-cause mortality risk associated with longitudinal loss of PMA. For each 1-cm2 PMA loss, mortality increased 3.1%(95%CI, 2.4%-3.7%; P< .001) in COPDGene, and 2.4%(95%CI, 0.9%-4.0%; P< .001) in ECLIPSE. Increased mortality risk was independent of enrollment values for BMI and disease severity [BODE (body mass, airflow obstruction, dyspnea, and exercise capacity) index quartiles] and was significant even in participants with initially greater than average PMA.InterpretationLongitudinal loss of PMA is associated with increased all-cause mortality, regardless of BMI or initial muscle mass. Consideration of novel screening tests and further research into mechanisms contributing to muscle decline may improve risk stratification and identify novel therapeutic targets in ever smokers.

Abstract

Background Attenuation of transforming growth factor β by blocking angiotensin II has been shown to reduce emphysema in a murine model. General population studies have demonstrated that the use of angiotensin converting enzyme inhibitors (ACEis) and angiotensin-receptor blockers (ARBs) is associated with reduction of emphysema progression in former smokers and that the use of ACEis is associated with reduction of FEV1 progression in current smokers. Research Question Is use of ACEi and ARB associated with less progression of emphysema and FEV1 decline among individuals with COPD or baseline emphysema? Methods Former and current smokers from the Genetic Epidemiology of COPD Study who attended baseline and 5-year follow-up visits, did not change smoking status, and underwent chest CT imaging were included. Adjusted linear mixed models were used to evaluate progression of adjusted lung density (ALD), percent emphysema (%total lung volume Results Over 5 years of follow-up, compared with nonusers, ACEi and ARB users with COPD showed slower ALD progression (adjusted mean difference [aMD], 1.6; 95% CI, 0.34-2.9). Slowed lung function decline was not observed based on phase 1 medication (aMD of FEV1 % predicted, 0.83; 95% CI, –0.62 to 2.3), but was when analysis was limited to consistent ACEi and ARB users (aMD of FEV1 % predicted, 1.9; 95% CI, 0.14-3.6). No effect modification by smoking status was found for radiographic outcomes, and the lung function effect was more pronounced in former smokers. Results were similar among participants with baseline emphysema. Interpretation Among participants with spirometry-confirmed COPD or baseline emphysema, ACEi and ARB use was associated with slower progression of emphysema and lung function decline.

Abstract

Contains fulltext : 194255.pdf (Publisher’s version ) (Open Access) BACKGROUND: Emphysema has considerable variability in its regional distribution. Craniocaudal emphysema distribution is an important predictor of the response to lung volume reduction. However, there is little consensus regarding how to define upper lobe-predominant and lower lobe-predominant emphysema subtypes. Consequently, the clinical and genetic associations with these subtypes are poorly characterized. METHODS: We sought to identify subgroups characterized by upper-lobe or lower-lobe emphysema predominance and comparable amounts of total emphysema by analyzing data from 9,210 smokers without alpha-1-antitrypsin deficiency in the Genetic Epidemiology of COPD (COPDGene) cohort. CT densitometric emphysema was measured in each lung lobe. Random forest clustering was applied to lobar emphysema variables after regressing out the effects of total emphysema. Clusters were tested for association with clinical and imaging outcomes at baseline and at 5-year follow-up. Their associations with genetic variants were also compared. RESULTS: Three clusters were identified: minimal emphysema (n = 1,312), upper lobe-predominant emphysema (n = 905), and lower lobe-predominant emphysema (n = 796). Despite a similar amount of total emphysema, the lower-lobe group had more severe airflow obstruction at baseline and higher rates of metabolic syndrome compared with subjects with upper-lobe predominance. The group with upper-lobe predominance had greater 5-year progression of emphysema, gas trapping, and dyspnea. Differential associations with known COPD genetic risk variants were noted. CONCLUSIONS: Subgroups of smokers defined by upper-lobe or lower-lobe emphysema predominance exhibit different functional and radiological disease progression rates, and the upper-lobe predominant subtype shows evidence of association with known COPD genetic risk variants. These subgroups may be useful in the development of personalized treatments for COPD.

Abstract

Background Chronic bronchitis (CB) increases risk of COPD exacerbations. We have shown that the St. George's Respiratory Questionnaire (SGRQ) CB definition identifies patients with a similar clinical phenotype as classically defined CB. Whether the SGRQ CB definition is a predictor of future COPD exacerbations is unknown. Methods We analyzed 7,557 smokers with normal spirometry and Global Initiative for Chronic Obstructive Lung Disease stage 1-4 COPD in the Genetic Epidemiology of COPD study with longitudinal follow-up data on exacerbations. Subjects were divided into classic CB+ or classic CB–, using the classic definition. In addition, subjects were divided into SGRQ CB+ or SGRQ CB–. Exacerbation frequency and severe exacerbation frequency were determined in each group. Multivariable linear regressions were performed for exacerbation frequency with either classic CB or SGRQ CB and relevant covariates. Results There were 1,434 classic CB+ subjects and 2,290 SGRQ CB+ subjects. The classic CB+ group had a greater exacerbation frequency compared with the classic CB– group (0.69 ± 1.26 vs 0.36 ± 0.90 exacerbations per patient per year; P Conclusions The SGRQ CB definition identified more subjects at risk for future exacerbations than the classic CB definition. SGRQ CB was at least a similar if not better predictor of future exacerbations than classic CB.

Abstract

BACKGROUND The risk factors for acute episodes of respiratory disease in current and former smokers who do not have COPD are unknown. METHODS Eight thousand two hundred forty-six non-Hispanic white and black current and former smokers in the Genetic Epidemiology of COPD (COPDGene) cohort had longitudinal follow-up (LFU) every 6 months to determine acute respiratory episodes requiring antibiotics or systemic corticosteroids, an ED visit, or hospitalization. Negative binomial regression was used to determine the factors associated with acute respiratory episodes. A Cox proportional hazards model was used to determine adjusted hazard ratios (HRs) for time to first episode and an acute episode of respiratory disease risk score. RESULTS At enrollment, 4,442 subjects did not have COPD, 658 had mild COPD, and 3,146 had moderate or worse COPD. Nine thousand three hundred three acute episodes of respiratory disease and 2,707 hospitalizations were reported in LFU (3,044 acute episodes of respiratory disease and 827 hospitalizations in those without COPD). Major predictors included acute episodes of respiratory disease in year prior to enrollment (HR, 1.20; 95% CI, 1.15-1.24 per exacerbation), airflow obstruction (HR, 0.94; 95% CI, 0.91-0.96 per 10% change in % predicted FEV 1 ), and poor health-related quality of life (HR, 1.07; 95% CI, 1.06-1.08 for each 4-unit increase in St. George's Respiratory Questionnaire score). Risks were similar for those with and without COPD. CONCLUSIONS Although acute episode of respiratory disease rates are higher in subjects with COPD, risk factors are similar, and at a population level, there are more episodes in smokers without COPD.

Abstract

Study objectives Bronchioloalveolar carcinoma is a primary lung neoplasm of variable histopathologic, radiologic, and clinical expression. There are three cell types described in bronchioloalveolar carcinoma: Clara cells, mucin-producing cells, and alveolar type II epithelial cells. It is unclear whether these three tumor cell types are associated with a specific radiologic presentation and clinical course. In this study, we investigated whether tumor cell type, identified by transmission electron microscopy, correlated with a specific radiologic pattern, and whether tumor cell type or radiologic presentation correlated with the patient's clinical course and outcome. Design Transmission electron microscopy was used to restudy tissue blocks from the original surgical histopathologic specimens in 54 patients with primary bronchioloalveolar carcinoma diagnosed over a 10-year period (1980 to 1990). The pretreatment radiographs were reviewed in each case, and the first chest radiograph obtained at the time of the discovery of the tumor in each patient was compared with the results of the ultrastructural study. The medical records of each patient were examined to obtain pertinent radiologic, clinical, and patient outcome information. Measurement and results There were 32 Clara cell tumors, 10 mucin-producing cell tumors, and 1 alveolar type II epithelial cell tumor in this series. Eleven additional tumors had mixtures of two or more cell types. No statistically significant relationship was detected between tumor cell type and radiologic presentation or patient mortality pattern. There was increased mortality among patients who presented radiologically with segmental, lobar, multifocal, or diffuse disease compared with those patients exhibiting a solitary pulmonary nodule at presentation. Conclusion Radiologic presentation, rather than tumor cell type, provides prognostic information that aids in predicting patient outcome.

Abstract

Study objective To determine the demographic, clinical, and radiographic characteristics of corticosteroid-treated patients with sarcoidosis who developed relapse following a period of clinical stability lasting longer than 1 month, and to compare these characteristics with those of a group of patients with sarcoidosis who were not treated. Design Historic, concurrent and prospective, nonrandomized, observational study. Setting Ambulatory sarcoidosis clinic in a university city hospital. Patients Over a 4-year calendar period, 337 patients with sarcoidosis were prospectively enrolled in a registry. One hundred eighteen patients were assigned to a spontaneous remission group when symptoms resolved without treatment, and 103 were assigned to an induced remission group when symptoms resolved following corticosteroid therapy and successful discontinuation. In 116 patients assigned to a recalcitrant group, therapy could not be stopped for 1 month or more owing to severity of symptoms or lack of compliance. We defined relapse as a recurrence of symptoms of sufficient severity to warrant treatment with corticosteroids, following a remission without treatment lasting greater than 1 month. Intervention Patients who were judged to be sufficiently symptomatic to preclude observation without treatment or who failed to respond to conservative treatment with topical or inhaled corticosteroids or nonsteroidal anti-inflammatory agents were treated with systemic corticosteroids at a target dose of 20 mg prednisone per day for 1 year. Measurements and results We observed a 74% relapse rate in the induced remission group, but only an 8% relapse rate in the spontaneous remission group (p Conclusions Relapse occurred frequently in patients with sarcoidosis who had been treated with corticosteroids, and rarely occurred in patients who had not been treated with corticosteroids in the past. The striking difference in relapse rate between treated and untreated patients suggests that patients with disease that would later be severe and protracted were almost unerringly identified early in their course. One explanation is that severe presenting symptoms portend a protracted and recurrent course; an alternative explanation is that corticosteroids contributed to the prolongation of the disease by delaying resolution.

Abstract

A 37-year-old white man presented with a productive cough, anorexia, weight loss, and night sweats of 4 months’ duration. He also complained of back pain with stiffness. The back pain was worse at night. He was treated for pneumonia 3 years ago and had a 20 pack-year history of smoking. He was a thin man in no distress. His vital signs were stable and temperature was 38.6°C (101.6°F). Bilateral enlarged firm but nontender axillary and inguinal lymph nodes were noted. Chest wall expansion was limited, but otherwise the thoracic examination was unremarkable. There was kyphosis of the lumbar spine with limited forward bending, The range of motion of the cervical spine was severely limited, and there was no lateral motion of the neck. The pelvis was anteverted, and there was a flexion deformity of both knees. Laboratory findings were as follows: WBC count, 11,300 cells/mL; and erythrocyte sedimentation rate, 30 mm/h. There was a positive human leukocyte antigenB27 antigen. Sputum smears and cultures for acid-fast bacilli were negative. Smears of BAL fluid and bronchial washings revealed rare acid-fast bacilli. The purified protein derivative skin test was negative. A chest radiograph (Fig 1) revealed bilateral upper lobe cavitary lesions. The remainder of the lungs were hyperinflated. There was mild upward retraction of the hilar structures indicating upper lobe volume loss. Contrast-enhanced chest CT (Fig 2) showed distortion of the lung architecture with
