Sex-Differences in Alpha-1 Antitrypsin Deficiency: Data From the EARCO Registry

BackgroundSex and gender influence many aspects of chronic obstructive pulmonary disease (COPD). Limited data are available on this topic in alpha-1 antitrypsin deficiency (AATD). We therefore aimed to investigate sex issues in the EARCO registry, a prospective, international, observational cohort study. MethodsBaseline data from PiZZ individuals, enrolled in the registry with complete data on sex and smoking history were analysed by group comparisons and binary logistic regression analyses. Results1283 patients with AATD, 49.3% women were analysed. Females reported less tobacco consumption (16.8±12.2 vs. 19.6±14.5 PY, p=0.006), occupational exposures towards gases, dusts or asbestos (p<0.005 each) and consumed less alcohol (5.5±7.6 vs. 8.4±10.3u/week, p<0.001). Females reported COPD (41% vs. 57%, p<0.001) and liver disease (11% vs. 20%, p<0.001) less often. However, they had a higher prevalence of bronchiectasis (24% vs. 13%, p<0.001). Despite better lung function (FEV1%pred. 73.6±29.9 vs. 62.7±29.5, p<0.001) females reported a similar symptom burden (CAT 13.4±9.5 vs. 12.5±8.9, p=ns) and exacerbation frequency (at least one in the previous year 30% vs. 26%, p=ns) compared to males. In multivariate analyses, female sex was an independent risk factor for exacerbations in the previous year OR 1.6 p=0.001 in addition to smoking history, COPD, asthma and bronchiectasis and was also identified as risk factors for symptom burden (CAT≥10) OR 1.4 p=0.014 besides age, BMI, COPD and smoking history. ConclusionMen had higher rates of COPD and liver disease, women were more likely to have bronchiectasis. Women's higher symptom burden and exacerbation frequency suggest they may need tailored treatment approaches.

Lung Damage in Rheumatoid Arthritis-A Retrospective Study.

The current study aimed to evaluate rheumatoid arthritis (RA) patients with interstitial lung disease (ILD) in clinical practice and whether disease characteristics are associated with X-ray and high-resolution computed tomography (HR-CT) findings. Medical history of RA patients from a tertiary rheumatology clinic was retrieved from its electronic database starting from 1 January 2019 until the study date (8 August 2022) using International Classification of Disease version 10 codes for RA, ILD and exclusion criteria. The study included 78 RA patients (75.6% women, 15.4% active smokers), with average time from RA to ILD of 5.6 years. Regarding chest X-ray findings, men had a higher prevalence of nodules, combined fibrosis and nodules and combined bronchiectasis and nodules, rheumatoid factor (RF)-positive patients had a higher prevalence of fibrosis and anti-cyclic citrullinated peptide antibodies (ACPA)-positive patients had a higher prevalence of bronchiectasis. Regarding HR-CT findings, patients actively treated with methotrexate had a higher prevalence of nodules; a combination of fibrosis and nodules; combination of emphysema and nodules; and combination of fibrosis, emphysema and nodules. ILD develops within approximately 5 years from RA diagnosis, and ILD-associated imaging findings on chest X-rays and HR-CT are more prevalent among men with RA, among patients with positive RA serology (RF and/or ACPA) and RA patients on methotrexate.

Computed Tomography in Adults with Bronchiectasis and Nontuberculous Mycobacterial Pulmonary Disease: Typical Imaging Findings

Among patients with bronchiectasis, nontuberculous mycobacterial pulmonary disease (NTM-PD) ranged between 1 and 6% and it is suspected that its prevalence is underestimated. Our aim was to evaluate differences in computed tomography (CT) features in patients with bronchiectasis, with and without NTM-PD, in order to facilitate earlier diagnosis in the future. In addition, we evaluated longitudinal changes after successful NTM-PD treatment. One hundred and twenty-eight CTs performed in adults with bronchiectasis were scored for the involvement, type, and lobar distribution of bronchiectasis, bronchial dilatation, and bronchial wall thickening according to Reiff. In addition, associated findings, such as mucus plugging, tree-in-bud, consolidations, ground-glass opacities, interlobular thickening, intralobular lines, cavities, and atelectasis, were registered. Patients with NTM-PD (n = 36), as defined by ATS/IDSA diagnostic criteria, were compared to bronchiectasis patients without NTM-PD (n = 92). In twelve patients with an available consecutive CT scan after microbiological cure of NTM-PD imaging findings were also scored according to Kim and compared in the course. In patients with NTM-PD, there was a higher prevalence of bronchiectasis in the middle lobes (p < 0.001), extended bronchiolitis (p = 0.032) and more small and large nodules (p < 0.001). Furthermore, cavities turned out to be larger (p = 0.038), and walls thickened (p = 0.019) and extended (p = 0.016). Patients without NTM more often showed peripheral ground-glass opacities (0.003) and interstitial changes (p = 0.001). CT findings decreased after successful NTM-PD treatment in the follow-up CT; however, without statistical significance for most features (p = 0.056), but bronchiolitis was the only significantly reduced score item (p = 0.043). CT patterns in patients with bronchiectasis and NTM-PD differ from those of patients with bronchiectasis without NTM-PD, although the findings are non-specific radiological features. Follow-up CT findings after microbiological cure differed interindividual regarding the decline in imaging features. Our findings may help practitioners to identify NTM-PD in patients with bronchiectasis. Further research is needed regarding the use of CT as a potential imaging biomarker for the evaluation of treatment response.

Prevalence of Bronchiectasis in Patients with Chronic Rhinosinusitis in a Tertiary Care Center

Whereas chronic rhinosinusitis (CRS) is associated with asthma, and vice versa, the association between CRS and other lower respiratory conditions is not well-established. Bronchiectasis is characterized by permanent damage of the airways, and as many as 45% of bronchiectasis patients have CRS, but the prevalence of bronchiectasis among CRS patients is not known. To determine the prevalence of bronchiectasis among CRS patients and to characterize demographic and clinical features of patients with bronchiectasis and CRS. Electronic medical records of patients with rhinosinusitis were searched by computer algorithm supplemented with manual chart review to identify patients with CRS, asthma, and/or bronchiectasis. Demographic and clinical features and antibiotic courses for sinopulmonary infections 2 years before and after sinus surgery were obtained by manual chart review. The prevalence of bronchiectasis as determined by International Classification of Diseases, Ninth Revision code was significantly higher in CRS patients than in asthmatic patients (2.3% vs 1.7%; P < .003). Similarly, based on a text word search of "bronchiectasis" in the chest computed tomography (CT) scan reports, patients with CRS who had chest CT scans had a higher prevalence of bronchiectasis than did asthmatic patients with chest CT scans (24.3% vs 19.5%; P= .005). Patients with CRS and concurrent bronchiectasis did not have a reduction in the frequency of sinopulmonary infections after sinus surgery compared with patients with CRS without bronchiectasis (P<.05). Bronchiectasis is an important comorbidity in patients with CRS and may identify a severe phenotype of chronic sinonasal disease.

Allergic-like disorders and asthma in patients with common variable immunodeficiency: a multi-center experience

Objective Common variable immune deficiency (CVID) encompasses a variety of diseases characterized by disturbed immunoglobulin (Ig) production and various immune dysregulations. Scarce data are available regarding relationships between CVID and allergic diseases. Here we examined possible associations between allergies and CVID. Methods For this multicenter study, we prospectively enrolled 79 adult CVID patients (≥18 years) who were diagnosed and treated between 2002–2017 at the Hadassah-Hebrew University and Shaare Zedek Medical Centers, Jerusalem, Israel. These patients were examined for allergic manifestations. Patient evaluation comprised medical history, physical examination, skin allergen testing, complete blood count, serum immunoglobulins, IgE levels, and pulmonary function tests. Results After implementing exclusion criteria, 29 patients were included in the final analysis. Allergic-like disorders were diagnosed in 65% of CVID patients with non-elevated serum IgE levels. Moreover, allergic CVID patients exhibited a higher prevalence of bronchiectasis on chest CT. Autoimmunity was diagnosed in 41.3% of CVID subjects. The type I allergy detected in our study was non-IgE mediated. Conclusions Timely diagnosis and stratification of allergy in CVID patients is expected to improve their outcome and quality of life, as well as promote appropriate treatment and better management of pulmonary exacerbations.

Bronchiectasis in common variable immunodeficiency: A systematic review and meta-analysis.

Common variable immunodeficiency (CVID) is the most prevalent symptomatic primary immunodeficiency disorder characterized by infectious and noninfectious complications. Bronchiectasis continues to be a common respiratory problem and therapeutic challenge in CVID. The aim of this study is to estimate the overall prevalence of bronchiectasis and its associated phenotype in patients with CVID. A systematic literature search was performed in Web of Science, PubMed, and Scopus from the earliest available date to February 2019 with standard keywords. All pooled analyses of bronchiectasis prevalence and the corresponding 95% confidence intervals (CIs) were based on random-effects models. Fifty-five studies comprising 8535 patients with CVID were included in the meta-analysis. Overall prevalence of bronchiectasis was 34% (95% CI: 30-38; I2 = 90.19%). CVID patients with bronchiectasis had significantly lower serum immunoglobulin A (IgA) and IgM levels at the time of diagnosis compared with those without bronchiectasis. Among the clinical features, the frequencies of splenomegaly, pneumonia, otitis media, and lymphocytic interstitial pneumonia were significantly higher in CVID patients with bronchiectasis compared with those without bronchiectasis, respectively. A higher prevalence of bronchiectasis in patients with CVID should be managed by controlling recurrent and severe pneumonia episodes which are immune dysregulation since this complication is associated with poor prognosis in these patients.

High prevalence of bronchiectasis on chest CT in a selected cohort of children with severe Asthma

BackgroundChest computed tomography (CT) scans have a recognised role in investigating adults with severe asthma to exclude alternative diagnoses, but its role in children is less clear. The objective of this study was to review the CT findings of our local cohort of children with severe asthma and to explore whether clinical or pathobiological parameters predicted CT changes.MethodsRetrospective observational single centre study including all children attending the Leicester difficult asthma clinic (DAC) who underwent a chest CT from 2006 to 2011. Additionally, we recruited eight age-matched, non-asthmatic controls to compare differences in CT findings between asthmatic and non-asthmatic children. All CT images were independently scored by two radiologists.The DAC patients were sub-divided into binary groups for each abnormality identified so that comparisons could be made against recorded clinical variables including age, lung function, serum total IgE levels, and sputum leukocyte differential cell counts.ResultsThirty DAC patients (median 12 yrs., range 5–16) were included.The most common abnormalities were bronchial wall thickening (BWT) and air trapping (AT), observed in 80 and 60% of DAC patients.Bronchiectasis (BE) was identified in 27% of DAC patients. DAC patients with evidence of BE on CT images were older than those without BE (13.9 ± 0.67 vs 11.5 ± 0.61, p = 0.038). We also identified a positive correlation between increasing BE severity and extent with age (r = 0.400, p = 0.028).ConclusionAbnormal CT findings were highly prevalent in our cohort of children with severe asthma, with bronchiectasis identified in approximately one third of children. We found no alternative diagnoses that resulted in a change in clinical management.

High prevalence of bronchiectasis in emphysema-predominant COPD patients.

BackgroundCOPD has been identified as an etiology or related disease of bronchiectasis, and bronchiectasis has been classified as a comorbidity of COPD. In this study, we investigated the prevalence of bronchiectasis in different phenotypes of COPD subjects and the correlation between bronchiectasis and different phenotypes, especially emphysema.MethodsCOPD patients were recruited from April 2012 to December 2015. The presence of bronchiectasis and related information were statistically analyzed. COPD subjects were separated into subgroups in two ways: COPD with and without bronchiectasis groups and emphysema-predominant (emphysema index, EI≥9.9%) and non-emphysema-predominant (EI<9.9%) groups.ResultsIn total, 1,739 COPD patients were incorporated into the study, among which 140 cases (8.1%) were accompanied with radiological bronchiectasis. COPD patients with concomitant bronchiectasis presented worse pulmonary function (FEV1% predicted, P<0.001), higher EI (15.0% vs 13.4%, P<0.001), and higher proportion of pulmonary hypertension and cor pulmonale (6.4% vs 2.4%, P=0.005 and 23.6% vs 16.1%, P=0.022) than patients without bronchiectasis. Of all the COPD patients, 787 with EI data were divided into emphysema-predominant (n=369) and non-emphysema-predominant groups (n=418). The proportion of bronchiectasis was 16.5% and 10.3% (P=0.01), respectively. Severity of bronchiectasis increased as the degree of airflow limitation (r=−0.371, P<0.001) and emphysema increased (r=0.226, P=0.021). After adjusting confounding factors, FEV1% predicted (OR, 1.636; 95% CI, 1.219–2.197; P=0.001) and EI (OR, 1.993; 95% CI, 1.199–3.313; P=0.008) were significantly related with the presence of bronchiectasis in COPD patients.ConclusionThe proportion of bronchiectasis is higher in emphysema-predominant COPD subjects. Emphysema measured by EI and FEV1% predicted are independent predictors for bronchiectasis in COPD subjects, while the underlying mechanism deserves further investigation.

Study of bronchiectasis phenotype and the common pathogens involved in late COPD stages

Background Chronic obstructive pulmonary disease (COPD) and bronchiectasis have many common characteristics from the physiopathologic and clinical points of view. Reviewing literature showed presence of a linear relationship between the appearance of bronchiectasis and the severity of COPD, with a higher prevalence of bronchiectasis in patients with COPD above that of the general population. Patients and methods The study included 60 male patients who smoked, ranging in age from 47 to 80 years old, with mean age of 59.37±7.87 years, and who were diagnosed with COPD according to the national standard. They were classified according to severity of airway obstruction using spirometric measurements and underwent high-resolution tomographic scan; moreover, sputum samples were collected for bacterial culture. Results The present study included 60 cases; all were male patients who smoked. Among the studied population, bronchiectasis was found in 56.7%, with more in severe cases. Conclusion Bronchiectasis had higher prevalence in patients with moderate to severe COPD. This was also associated with colonization of airways with pathogenic micro-organisms.

CT features of normal lung change in asymptomatic elderly patients

Abstract Background Not all morphological lung changes in the elderly contribute to respiratory disease and may be a consequence of normal aging. Objectives To describe the changes in asymptomatic elderly patients compared with those in younger patients in a Thai population. Methods The study cohort comprised 60 participants without respiratory symptoms in three groups of 20 by age: 20-40 years, 41-60 years, and &gt;60 years. Participants were prospectively selected from patients referred for computed tomography (CT) of the abdomen, or head and neck, and underwent sequential CT during deep breathing at four lung levels. Two observers scored images by consensus. We compared groups using Pearson chi-square and Fisher exact tests, and used receiver operating characteristic curves to categorize bronchiectasis and bronchial wall thickening by age. Results Air trapping was related to age (5/20 group 1, 7/20 group 2, and 18/20 group 3 (P &lt;0.01)) and was most prevalent in lower lobes (78%, P &lt; 0.01). Reticulation was found in only one middle aged patient (P = 0.36). Bronchiectasis was more common in patients &lt;56 years (7/23) than &lt;56 years (3/37), P = 0.035. Bronchial wall thickening (7/23 in patients &gt;56 years and 2/37 in patients &lt;56 years, P = 0.02) and extensive air trapping were related to age (0/6 group 1, 1/6 group 2, and 5/6 group 3, P = 0.02). Findings were independent of smoking history. Conclusions Asymptomatic older patients had higher prevalence of bronchiectasis, bronchial wall thickening, and air trapping, independent of smoking history.

Colonization and Bronchiectasis in Patients with Advanced Chronic Obstructive Pulmonary Disease

Background: Pathogenic organisms in sputum of COPD patients are associated with increased risk of exacerbations and with a higher prevalence of bronchiectasis. This study evaluates the rate of colonization in patients with advanced COPD, along with severity of bronchiectasis. Methods: A retrospective single-center evaluation of 378 patients with advanced COPD was performed in our pretransplant outpatient clinic between October 2008 and June 2011. Lung function, exacerbation rate in the preceding 12 months and lung and sputum microbiology were analyzed. CT scans were assessed for bronchiectasis by blinded radiologists. Results: Sputum expectoration was reported in 196 patients (52%). Potential pathogens were identified in 77 cases (20%), Pseudomonas aeruginosa (20%) and Staphylococcus aureus (21%) were the dominant bacterials. Patients with positive sputum cultures were more likely to be hospitalized due to exacerbation (p=0.01) and demonstrated more severe bronchiectasis in standardized qualitative CT examination (p=0.002). Ninety-four patients (25%) underwent lungtransplantation during the observation period. In the explanted lungs, evidence of potential pathogen was found in 21 patients (22%). Conclusions: Within our cohort of advanced COPD patients, almost 1 of 5 patients exhibited a positive respiratory culture. Pathogenic bacterial colonisation correlated with more severe bronchiectasis and significantly increased hospitalization due to exacerbations.

Factors associated with bronchiectasis in patients with moderate-severe chronic obstructive pulmonary disease.

A high prevalence of bronchiectasis was found by chest computed tomography (CT) in patients with moderate–severe chronic obstructive pulmonary disease (COPD), and it was shown to be associated with more severe symptoms, higher frequency of exacerbations and mortality. The risk factors for bronchiectasis in COPD are not yet clarified.High-resolution computed tomography (HRCT) of chest was performed in patients with moderate–severe COPD, and the presence and the extent of bronchiectasis were evaluated by two radiologists. Demographic data, respiratory symptoms, lung function, previous pulmonary tuberculosis, serum inflammatory markers, serum total immunoglobulin E (T-IgE), and sputum culture of Pseudomonas aeruginosa were compared between those with and without bronchiectasis. Multivariate logistic regression analysis was used to determine the independent factors associated with bronchiectasis.We enrolled 190 patients with stable COPD, of which 87 (87/190, 45.8%) had bronchiectasis on HRCT. Compared with those without bronchiectasis, COPD patients with bronchiectasis were more likely to be males (P = 0.021), had a lower body mass index (BMI) (P = 0.019), a higher prevalence of previous tuberculosis (P = 0.005), longer history of dyspnea (P < 0.001), more severe dyspnea (P = 0.041), higher frequency of acute exacerbation (P = 0.002), higher serum concentrations of C-reactive protein (CRP) (P = 0.017), fibrinogen (P = 0.016), and T-IgE [P = 0.004; for log10(T-IgE), P <0.001]. COPD patients with bronchiectasis also showed poorer lung function (for FEV1/FVC, P = 0.013; for FEV1%predicted, P = 0.012; for global initiative for chronic obstructive lung disease (GOLD) grades, P = 0.035), and a higher positive rate of sputum P aeruginosa (P = 0.020). Logistic regression analysis demonstrated that male gender (P = 0.021), previous tuberculosis (P = 0.021), and increased level of serum T-IgE [for log10(T-IgE), P < 0.001] were risk factors for coexistent bronchiectasis. More notably, the level of serum T-IgE [log10(T-IgE)] was positively correlated with the extent of bronchiectasis in COPD patients (r = 0.208, P = 0.05).Higher serum T-IgE, male gender, and previous tuberculosis are independent risk factors for coexistent bronchiectasis in COPD. The association of T-IgE with the extent of bronchiectasis also suggests that further investigations are needed to explore the potential role of IgE in the pathogenesis of bronchiectasis in COPD.

High prevalence of bronchiectasis is linked to HTLV-1-associated inflammatory disease.

BackgroundHuman T-lymphotropic virus type 1 (HTLV-1), a retrovirus, is the causative agent of HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) and adult T-cell leukaemia/lymphoma (ATLL). The reported association with pulmonary disease such as bronchiectasis is less certain.MethodsA retrospective case review of a HTLV-1 seropositive cohort attending a national referral centre. The cohort was categorised into HTLV-1 symptomatic patients (SPs) (ATLL, HAM/TSP, Strongyloidiasis and HTLV associated inflammatory disease (HAID)) and HTLV-1 asymptomatic carriers (ACs). The cohort was reviewed for diagnosis of bronchiectasis.Result34/246 ACs and 30/167 SPs had been investigated for respiratory symptoms by computer tomography (CT) with productive cough +/- recurrent chest infections the predominant indications. Bronchiectasis was diagnosed in one AC (1/246) and 13 SPs (2 HAID, 1 ATLL, 10 HAM/TSP) (13/167, RR 19.2 95 % CI 2.5-14.5, p = 0.004) with high resolution CT. In the multivariate analysis ethnicity (p = 0.02) and disease state (p < 0.001) were independent predictors for bronchiectasis. The relative risk of bronchiectasis in SPs was 19.2 (95 % CI 2.5-14.5, p = 0.004) and in HAM/TSP patients compared with all other categories 8.4 (95 % CI 2.7-26.1, p = 0.0002). Subjects not of African/Afro-Caribbean ethnicity had an increased prevalence of bronchiectasis (RR 3.45 95 % 1.2-9.7, p = 0.02).ConclusionsBronchiectasis was common in the cohort (3.4 %). Risk factors were a prior diagnosis of HAM/TSP and ethnicity but not HTLV-1 viral load, age and gender. The spectrum of HTLV-associated disease should now include bronchiectasis and HTLV serology should be considered in patients with unexplained bronchiectasis.

High Prevalence of Bronchiectasis in Adults: Analysis of CT Findings in a Health Screening Program

Bronchiectasis is one of the common chronic respiratory diseases and associated with respiratory morbidity and mortality. However, neither its prevalence nor its etiology is well-defined. We aimed to estimate the prevalence and risk factors of bronchiectasis in adults. In a retrospective study, we analyzed radiologic findings on chest computed tomography (CT) images performed as part of a health-screening program. From January to December 2008, 1,409 (24.6%) of 5,727 participants in the screening program of a health promotion center at a university hospital underwent chest CT scans based on the subject's decision. Bronchiectasis was diagnosed, if there was abnormal bronchial dilatation in any area of both lungs on chest CT. Respiratory symptoms, smoking status, and past medical history were also analyzed to define clinical characteristics and risk factors of bronchiectasis. Of 1,409 patients (aged 23-86 years), who were screened for respiratory diseases using chest CT for one year in a health promotion center, 129 patients (9.1%) were diagnosed with bronchiectasis. The prevalence of bronchiectasis was higher in females than in males (11.5% vs. 7.9%, p = 0.022) and increased with age. Respiratory symptoms were reported in 53.7% of subjects. Previous history of tuberculosis (TB) (OR 4.61, 95% CI 2.39-8.88, p = 0.001) and age (OR 2.49, 95% CI 1.56-3.98, p = 0.001) were significantly associated with bronchiectasis. This retrospective analysis of chest CT findings in health screening examinees revealed a very high prevalence of bronchiectasis in adults. Previous TB infection is one of the major causes of bronchiectasis.

Common variable immune deficiency: respiratory manifestations, pulmonary function and high-resolution CT scan findings.

Common variable immune deficiency (CVID) is prone to under-diagnosis and may not reach relevant specialists until late in life. Morbidity is most commonly due to acute-on-chronic respiratory infections leading to respiratory failure. To investigate respiratory complications, lung function and high-resolution computerized tomography scan (HRCT) findings and mortality in 47 patients with CVID. A regional immunology unit (Birmingham Heartlands Hospital). Retrospective observational case-note study following the introduction of shared care between immunology and respiratory medicine. Age at diagnosis ranged from 5 to 72 years, with a median time from development of first symptoms to diagnosis of 4.0 years. There was delay in referral between chest physicians and immunologists, (median referral time between specialities >5 years). Forty-two patients had respiratory complications, due to bronchiectasis (n=32), asthma (n=7), recurrent chest infections (n=9) without concomitant evidence of structural lung damage, and granulomatous lung disease (n=2). Spirometry was abnormal in 10/39 patients (7 obstructive, 3 restrictive). Bronchiectasis was confirmed on chest radiograph (n=9) and HRCT (n=24). Despite the high prevalence of bronchiectasis, few patients had received instruction in physiotherapy and sputum culture results were sparse. To reduce the morbidity associated with CVID, there needs to be greater awareness of respiratory complications, particularly amongst physicians caring for such patients. Emphasis has been placed on adequate dosage of immunoglobulin, but early involvement by a respiratory physician is essential to monitor lung function and initiate optimal therapy, to minimize the occurrence and progression of lung damage.
