RESUMO
PURPOSE OF REVIEW: This review examines current research on healthcare disparities in pancreatitis, identifies knowledge gaps, and proposes strategies to develop targeted multilevel interventions to address inequities in pancreatitis care. RECENT FINDINGS: Current literature has identified patient, disease, and healthcare-level factors contributing to disparities in risk factors and health outcomes of pancreatitis. Moreover, social structures, economic systems, social vulnerability, and policy significantly influence the pancreatitis care continuum. SUMMARY: Understanding the root causes of health inequities is critical to developing effective approaches for the prevention, early detection, and management of pancreatitis.

BACKGROUND: Nebulized Hypertonic saline (HS) and positive expiratory pressure device (PEP) are often used in patients with bronchiectasis. We sought to describe the clinical characteristics in patients using HS and PEP, utilizing a large national database registry. METHODS: Data from the US Bronchiectasis and NTM Research Registry were used in this study. Patients with a diagnosis of bronchiectasis were included. Eligible patients were assigned to one of four mutually exclusive groups: HS only, PEP only, HS & PEP, or no airway clearance or mucoactive agent. Descriptive statistics were computed for the overall study population and stratified by the four groups. One-way ANOVA and chi-square tests were used to test the difference in the means in continuous variables and the association between categorical variables (respectively) across the four groups. RESULTS: A total of 2195 patients were included. Of those with bronchiectasis and a productive cough, a greater number of patients utilized HS only vs PEP only (17.5 % vs 9.1 %, p < 0.001). Similar association was found in those with Pseudomonas aeruginosa (22.3 % HS only vs 6.5 % PEP only, p < 0.001). There was a higher number of patients who used HS and PEP therapy in combination vs PEP therapy alone (25.0 % vs 9.1 %, p = 0.002), in those with a productive cough. CONCLUSIONS: In patients with bronchiectasis and a productive cough or Pseudomonas aeruginosa, HS is used more often than PEP alone. There is a need for further analysis to compare these two modalities and explore the factors influencing their utilization.
RESUMO
OBJECTIVES: Patients with chronic illnesses are susceptible to the financial burden of disease-related treatment costs. Financial toxicity is well-researched in cancer and several chronic diseases. This review explores the financial challenges faced by patients with chronic pancreatitis and the impact of financial hardship on their well-being. METHODS: We performed a review of the published literature to summarize the body of existing research and to identify knowledge gaps related to the financial burden experienced by patients with chronic pancreatitis. RESULTS: Research on financial burden, cost-coping behaviors, cost-related nonadherence to prescribed medications, and social vulnerabilities in people with chronic pancreatitis is sparse. No studies have assessed the suitability and validity of instruments measuring subjective financial toxicity in a patient population with chronic pancreatitis. CONCLUSIONS: There is a critical need for further studies of financial toxicity in the patient population with chronic pancreatitis, considering that if the sources of financial burden can be identified, opportunities emerge to dampen or mitigate their impact on patients with chronic pancreatitis.
RESUMO
BACKGROUND: This study aimed to evaluate the association between the number of non-cystic fibrosis bronchiectasis (bronchiectasis) exacerbations during baseline and follow-up (objective 1) and to identify longitudinal changes in FEV1 associated with exacerbation frequency (objective 2). METHODS: This was a retrospective cohort study of adult patients enrolled in the US Bronchiectasis and Nontuberculous Mycobacteria Research Registry September 2008 to March 2020. Objective 1 outcome was association between exacerbations during baseline (24 months) and 0-to-24 month and 24-to-48 month follow-up windows. Objective 2 outcomes were change in FEV1 and FEV1 % predicted over 24 months stratified by baseline exacerbation frequency. RESULTS: Objective 1 cohort (N = 520) baseline frequency of any exacerbations was 59.2%. Overall, 71.4% and 75.0% of patients with ≥1 baseline exacerbations had ≥1 exacerbations during the 0-to-24 and 24-to-48 month follow-ups. Having ≥1 exacerbation during baseline was significantly associated with ≥1 exacerbation during the 0-to-24 month (P = 0.0085) and 24-to-48 month follow-ups (P=<0.0001). Objective 2 cohort (N = 431) baseline FEV1 was significantly lower in patients who had more exacerbations; however, decline in FEV1 from baseline was not significantly different between patients with 0, 1, and ≥2 exacerbations. In patients with more baseline exacerbations, FEV1 % predicted was significantly lower at baseline (P < 0.0001) and at 12 (P = 0.0002) and 24 month follow-ups (P < 0.0001). CONCLUSIONS: Patients with frequent bronchiectasis exacerbations may be more likely than those with less frequent exacerbations to experience disease progression based on future exacerbation frequency and lower FEV1 at baseline, although FEV1 decline may not differ by baseline exacerbation frequency.

Background: Health-related quality of life (HRQoL) assessments such as St. George's Respiratory Questionnaire (SGRQ) are often used as outcome measures to evaluate patient-perceived changes in health status among individuals with lung disease. Several factors have been linked to deterioration in SGRQ, including symptoms (dyspnea, wheezing) and exercise intolerance. Whether these findings apply to individuals with alpha-1 antitrypsin deficiency (AATD) remains incompletely studied. This longitudinal study examines the trajectory of SGRQ scores in a cohort of United States individuals with AATD-associated lung disease and defines factors associated with longitudinal change. Methods: Individuals with AATD-associated lung disease enrolled in AlphaNet, a disease management program, who had ≥3 SGRQ measurements collected between 2009 and 2019, and baseline data for clinically important variables were included in these analyses. Data collected after lung transplants were excluded. Mixed-effects model analyses were used to evaluate the changes in SGRQ total and subscale scores over time and by modified Medical Research Council (mMRC) Scale, use of oxygen, age, sex, productive cough, and exacerbation frequency at baseline. Sensitivity analyses were conducted to examine the potential effect of survivor bias. Results: Participants (n=2456, mean age 57.1±9.9 years, 47% female) had a mean SGRQ total score of 44.7±18.9 at baseline, 48% used oxygen regularly, and 55% had ≥2 exacerbations per year. The median length of follow-up was 6 (IQR 3-9) years. The SGRQ total score and subscales remained stable throughout the observation period. Age, mMRC categories, presence or absence of productive cough, frequency of exacerbations, and use of oxygen at baseline were significantly associated with the rate of change of SGRQ total (p<0.0001). Conclusion: We observed long-term stability in HRQoL and an association between the rate of change in SGRQ and baseline mMRC, exacerbation frequency, productive cough, and use of oxygen in this cohort of individuals with AATD-associated lung disease.

Rationale: Nontuberculous mycobacteria (NTM) are prevalent among patients with bronchiectasis. However, the long-term natural history of patients with NTM and bronchiectasis is not well described. Objectives: To assess the impact of NTM on 5-year clinical outcomes and mortality in patients with bronchiectasis. Methods: Patients in the Bronchiectasis and NTM Research Registry with ⩾5 years of follow-up were eligible. Data were collected for all-cause mortality, lung function, exacerbations, hospitalizations, and disease severity. Outcomes were compared between patients with and without NTM at baseline. Mortality was assessed using Cox proportional hazards models and the log-rank test. Measurements and Main Results: In total, 2,634 patients were included: 1,549 (58.8%) with and 1,085 (41.2%) without NTM at baseline. All-cause mortality (95% confidence interval) at Year 5 was 12.1% (10.5%, 13.7%) overall, 12.6% (10.5%, 14.8%) in patients with NTM, and 11.5% (9.0%, 13.9%) in patients without NTM. Independent predictors of 5-year mortality were baseline FEV1 percent predicted, age, hospitalization within 2 years before baseline, body mass index, and sex (all P < 0.01). The probabilities of acquiring NTM or Pseudomonas aeruginosa were approximately 4% and 3% per year, respectively. Spirometry, exacerbations, and hospitalizations were similar, regardless of NTM status, except that annual exacerbations were lower in patients with NTM (P < 0.05). Conclusions: Outcomes, including exacerbations, hospitalizations, rate of loss of lung function, and mortality rate, were similar across 5 years in patients with bronchiectasis with or without NTM.

BACKGROUND: Generic measures of health-related quality of life (HRQoL), such as the 36-Item Short Form Survey (SF-36), are widely used in assessing chronic conditions. These tools have an advantage over disease-specific instruments, as they allow comparisons across different health conditions and with the general population. In alpha-1 antitrypsin deficiency (AATD)-associated chronic obstructive pulmonary disease (COPD), HRQoL research remains scarce. This cross-sectional study evaluates the factors associated with HRQoL in a cohort of patients with AATD-associated COPD. METHODS: Our study included participants of AlphaNet (2008-2019), a health management organization for people with AATD in the US who are prescribed augmentation therapy. Norm-based SF-36 scores for the mental and physical component summary scores (MCS and PCS, mean of 50 ± 10 in the general US population) and 8 individual scales were evaluated. Individuals with lung disease and data available on ≥1 measurement on any SF-36 scale and clinically relevant characteristics such as modified Medical Research Council (mMRC) scale, exacerbation frequency, productive cough, and use of oxygen were included in these analyses. Generalized linear regression models were fit to examine the association of baseline characteristics with MCS and PCS scores. Age, sex, regular use of oxygen, exacerbation frequency, mMRC, and productive cough were included in these models. RESULTS: Participants (n=4398, mean age 57.6 [SD=10.6] years, 45.4% female) had a mean MCS score of 51.2 ± 10.8 and PCS of 36.3 ± 9.8. The average mMRC score was 2.4 ± 1.3, and 56.4% had 2 or more exacerbations per year. Overall, the physical component of SF-36 was more severely impacted compared to the mental component. In multivariable regression analyses, PCS scores were significantly associated with exacerbation frequency, mMRC, regular use of oxygen, and productive cough; MCS was associated with age, sex, exacerbation frequency, mMRC, and productive cough. CONCLUSIONS: These findings demonstrate that patient-perceived physical health is significantly impaired in this cohort of people with AATD-associated COPD compared to mental health. Longitudinal studies are needed to evaluate the change in physical and mental health status over time in this population.

BACKGROUND: High frequency chest wall oscillation (HFCWO) is a form of airway clearance therapy that has been available since the mid-1990s and is routinely used by patients suffering from retained pulmonary secretions. Patients with cystic fibrosis (CF), neuromuscular disease (NMD), and other disorders, including bronchiectasis (BE) and COPD (without BE), are commonly prescribed this therapy. Limited evidence exists describing HFCWO use in the BE population, its impact on long-term management of disease, and the specific patient populations most likely to benefit from this therapy. This study sought to characterize the clinical characteristics of patients with BE who have documented use of HFCWO at baseline and 1-year follow-up. METHODS: An analysis from a large national database registry of patients with BE was performed. Demographic and clinical characteristics of all patients receiving HFCWO therapy at baseline are reported. Patients were stratified into two groups based on continued or discontinued use of HFCWO therapy at 1-year follow-up. RESULTS: Over half (54.8 %) of patients who reported using HFCWO therapy had a Modified Bronchiectasis Severity Index (m-BSI) classified as severe, and the majority (81.4 %) experienced an exacerbation in the prior two years. Of patients with 1-year follow-up data, 73 % reported continued use of HFCWO. Compared to patients who discontinued therapy, these patients were more severe at baseline and at follow-up suggesting that patients with more severe disease are more likely to continue HFCWO therapy. CONCLUSIONS: Patients who have more severe disease and continue to experience exacerbations and hospitalizations are more likely to continue HFCWO therapy. CLINICAL TRIAL REGISTRATION: NA.

Aim: Alpha-1 antitrypsin deficiency is an autosomal co-dominant condition that predisposes individuals to early-onset emphysema. As with COPD, AATD-COPD is associated with pulmonary exacerbations, which impacts on overall mortality and quality of life. Though there is evidence that COPD is associated with a higher prevalence of cardiovascular disease and major adverse cardiovascular events (MACE), it is unclear if this is true for patients with AATD-COPD. Methods: Prevalence of cardiovascular disease was determined in two separate severe AATD cohorts: AlphaNet, USA and the Birmingham AATD registry, UK. All patients had preexisting lung disease. Cardiovascular disease was defined as presence of any of the following: heart failure, ischaemic heart disease, atrial fibrillation, stroke, and myocardial infarction. A Cox proportional hazards model was used to assess the impact of prior cardiovascular disease and frequent exacerbator phenotype on risk of future MACE. Results: Out of 3493 patients with severe AATD, 14.7% had prior cardiovascular disease, including stroke (2.3%), myocardial infarction (2.2%), and heart failure (2.5%). Frequent exacerbators were more likely to have preexisting cardiovascular disease compared with those with one or no exacerbations in the preceding year (63% vs 44.8%, p = 0.001). There was increased risk of future MACE in frequent exacerbators (HR 1.85, 95% CI 1.24 to 2.75), former and current smokers (HR 1.80, 95% CI 1.07 to 3.02, p = 0.026, and HR 4.04, 95% CI 1.44 to 11.32, p = 0.008, respectively), and those with prior cardiovascular disease (HR 3.81, 95% CI 2.60 to 5.58, p < 0.001). Conclusion: In severe AATD-COPD, MACE are associated with an increased exacerbation frequency, previous cardiovascular disease, and a history of smoking.

RATIONALE: Longitudinal epidemiological and clinical data are needed to improve the management of patients with bronchiectasis developing nontuberculous mycobacterial (NTM) pulmonary disease. OBJECTIVES: To describe the epidemiology, patient management, and treatment outcomes of NTM infections in patients with bronchiectasis enrolled in the United States Bronchiectasis and NTM Research Registry (US BRR). METHODS: This was a retrospective cohort study of patients with bronchiectasis and NTM infections enrolled with follow-up in the US BRR in 2008-2019. The study included patients with ≥1 positive NTM respiratory culture in the 24-month baseline period (baseline NTM cohort) and/or during the annual follow-up visits (incident NTM cohort). Incidence, prevalence, baseline patient characteristics, treatment exposure, treatment outcomes, and respiratory clinical outcomes were described in the baseline NTM cohort, incident NTM cohort, and both cohorts combined (prevalent NTM cohort). RESULTS: Between 2008 and 2019, 37.9% (1457/3840) of patients with bronchiectasis in the US BRR met the inclusion criteria for this study and were reported to have Mycobacterium avium complex (MAC) and/or Mycobacterium abscessus complex (MABSC) infections. MAC prevalence increased steadily in the US BRR during 2009-2019; incidence was relatively stable, except for a peak in 2011 followed by a slow decrease. MABSC and mixed MAC/MABSC infections were rare. Most patients with bronchiectasis and NTM infections in the registry were female, White, and aged >65 years. The antibiotics administered most commonly reflected current guidelines. In the prevalent cohort, 44.9% of MAC infections and 37.1% of MABSC infections remained untreated during follow-up, and MAC treatment was initiated with delay (>90 days after positive NTM respiratory culture) twice as frequently as promptly (≤90 days after positive NTM respiratory culture) (68.6% vs 31.4%, respectively). The median time from diagnosis to treatment was shorter for MABSC versus MAC infections (194.0 days [interquartile range (IQR) 8.0, 380.0] vs 296.0 days [IQR 35.0, 705.0], respectively). Among patients with MAC infections who completed treatment, 27.6% were classified as cured and 29.6% as treatment failure during the annual follow-up visit window. For MABSC, these proportions were 25.0% and 28.0%, respectively. CONCLUSIONS: A considerable proportion of MAC and MABSC infections were untreated or treated after initial delay/observation. MABSC infections were more likely to be treated and start treatment sooner than MAC infections. Further longitudinal studies are warranted to evaluate the monitor-with-delay approach and inform clinical guidelines.

Background: Intravenous alpha-1 antitrypsin (AAT) augmentation therapy is the only specific treatment available for alpha-1 antitrypsin deficiency (AATD)-related lung disease. It is widely used worldwide but remains unavailable to patients with AATD in the United Kingdom. While randomized trials of augmentation therapy have demonstrated biochemical efficacy and lung tissue preservation using computed tomography (CT) densitometry, these studies were not adequately powered to demonstrate effectiveness in well-accepted clinical endpoints such as quality of life (QOL) or survival. We used large, prospectively followed AATD patient populations in the United States and United Kingdom to explore these important clinical endpoints. Methods: Our inclusion criterion was adults with severe AATD and associated lung disease. The treatment group was U.S. AATD patients receiving augmentation therapy for lung disease. The control group was augmentation therapy naïve AATD patients. Multivariable regression and survival analyses were used to assess QOL and mortality outcomes respectively. Results: Mean annual deterioration of the St George's Respiratory Questionnaire total score was 1.43 points greater/year in the control group compared to those receiving augmentation therapy (95% confidence interval [CI] 0.47 to 2.39, p=0.003). At 7 years, median survival was 82.7% (95% CI 75.3 to 90.7) for the control group versus 87.8% (95% CI 82.8 to 93.2) in the augmentation group, p=0.66. There was significant heterogeneity between cohorts. Conclusions: A comparison of 2 highly characterized AATD cohorts was not able to reliably determine if AAT augmentation therapy improves QOL or mortality in patients with severe AATD-related lung disease. Alternative surrogate biomarkers of disease progression, such as CT lung density, may be a more pragmatic option.
RESUMO
Rationale: Identifying pulmonary exacerbations in patients with alpha-1 antitrypsin deficiency (AATD) is critical as they are associated with disease progression and poor health-related quality of life. Not all changes in usual respiratory symptoms will be identified as exacerbations by patients with AATD. Methods: Data collected via regular monthly telephone calls during the first year of the AlphaNet Step Forward Study were analyzed. AlphaNet subscribers were asked about changes in their usual respiratory symptoms, whether they considered changes in symptoms to be pulmonary exacerbations, and their management. Participants who reported changes in their usual respiratory symptoms throughout the year were included in the study. Per-patient and per-event analyses were performed. Results: Participants (n=316, age 58±10 years, 53% female) reported 797 events of changes in their usual respiratory symptoms in 1 year. Almost half (48%) of these symptom events were identified as pulmonary exacerbations by the study participants. The average number of symptoms was higher in events recognized by participants as exacerbations than those not identified as exacerbations (3.3±1.5 versus 1.8±1.1, respectively). A greater proportion of the exacerbation events were managed by taking antibiotics or corticosteroids or both (81%, 53%, and 41% of the events, respectively). With exacerbations, participants mainly spoke to the pulmonary specialist (39%) or went to the doctor's office (37%). Symptom events not recognized as exacerbations were mostly self-treated (56%). Conclusions: Changes in usual pulmonary symptoms are not universally recognized as exacerbations. Patients' perspectives in recognizing changes in pulmonary symptoms as exacerbation events are critical.
RESUMO
INTRODUCTION: Little information is available about Stenotrophomonas maltophilia in patients with bronchiectasis. We analyzed data from the US Bronchiectasis and NTM Research Registry to determine its prevalence and association with patient characteristics and severity of disease. METHODS: Baseline and follow-up data were entered into a central web-based database. Patients were grouped into four cohorts based on their baseline cultures: 1) S. maltophilia, no Pseudomonas aeruginsosa, 2) P. aeruginosa, no S. maltophilia, 3) No pathogens, 4) Pathogens other than P. aeruginosa and S. maltophilia. The association between S. maltophilia, demographic characteristics, pulmonary function, exacerbations and hospitalizations was assessed at baseline and one year follow-up. RESULTS: Among 2659 patients, 134 (5.0%) had grown S. maltophilia at baseline. The prior exacerbation rate at baseline was similar in patients with S. maltophilia and P. aeruginosa, but significantly higher than the other two groups. Hospitalizations were more frequent in patients with S. maltophilia or P. aeruginosa. Pre-bronchodilator FEV1 among S. maltophilia patients was between that of Pseudomonas patients and patients without either organism, but was not significantly different from any of the other groups. For all risk-adjusted one-year outcomes, patients with S. maltophilia had a non-significant trend towards worse outcomes compared to patients without P. aeruginosa, but were more similar to patients with P aeruginosa. DISCUSSION: Bronchiectasis patients with S. maltophilia may have worse outcomes than patients without this organism or without P. aeruginosa; further study is needed to determine if the non-significant trends we note are clinically significant.

PURPOSE: Pharmacotherapy is one cornerstone of Chronic Obstructive Pulmonary Disease (COPD) management. Published U.S. data seldom includes patient-reported COPD medication use and adherence. We add this patient perspective to the commonly reported administrative prescribing and fill data. METHODS: This survey study used inhaler and nebulizer pictures and lists of oral COPD medications to query members of the COPD Foundation Patient-Powered Research Network, a national self-reported online registry. Medications used, adherence, inhaler education, cost concerns, previous exacerbations, and COPD Assessment Test scores were assessed and summarized using simple descriptive statistics and hazard ratios controlling for age, gender, and disease burden. RESULTS: Respondents mean age was 68 years, 60% were women, >69% with the COPD Assessment Test (CAT) scores >15, and >50% reported 2 or more exacerbations in the past 12 months. Overall, >98% used one or more inhaled COPD medications, 7.6% rescue inhaler only, 17.8% used long-acting bronchodilator only therapy (11.1% dual), and 72.8% using corticosteroid therapies, including 53% triple therapy. Nebulizers were used by 59.4% and 34.8% use oral COPD medications. Reported adherence rates were high (80.1%), but 41% reported trouble paying for medications, with 20.1% reported missing medications due to cost. CONCLUSIONS: In this population, COPD had a high burden with >50% of respondents using triple therapy, and one in eight maintenance oral corticosteroids. Self-reported adherence was high, but with significant cost concerns reported resulting in missed medications.
RESUMO
BACKGROUND: Electronic medication monitors (EMMs) are associated with decreased rescue inhaler use, symptom burden, and increased medication adherence in asthma. However, the use of EMMs in people with chronic obstructive pulmonary disease (COPD) using the ELLIPTA dry powder inhaler has not been studied. METHODS: This was an open-label, single-arm, prospective observational study of EMMs and associated application (app) use over 12 weeks and up to 24 weeks (April-October 2019) in people with self-reported COPD aged ≥40 years enrolled in the COPD Patient-Powered Research Network, using an ELLIPTA inhaler. The primary outcome was daily active use of the app over 12 weeks. Treatment adherence, rescue inhaler use, and participant satisfaction were assessed over the same period. RESULTS: Among the 122 participants, mean (standard deviation [SD]) proportion of days participants opened the app was 59.5% (31.4), 51.1% (33.5) and 41.3% (34.2) for Days 1-30, 31-60 and 61-90, respectively. Mean (SD) adherence to maintenance medication remained stable: 80.2% (22.7) and 79.9% (26.7) for Days 1-30 and 61-90, respectively. In participants using a rescue inhaler and EMM, mean (SD) rescue-free days increased from 18.5 (10.0; Days 1-30, n=51) to 21.4 (9.6; Days 61-90, n=48). Participants reported high levels of confidence in using the EMM, valued app reminders highly and reported high system satisfaction (mean [SD] scale: 1=low, 5=high; 4.6 [1.1], 4.3 [1.1] and 4.1 [1.1], respectively). CONCLUSIONS: Use of an ELLIPTA EMM with frequent app engagement, high participant satisfaction and decreased rescue medication use may aid COPD management.

PURPOSE: Respiratory diseases caused by nontuberculous mycobacteria (NTM) have become a significant concern for patients and health care providers. We aimed to compare symptoms experienced during the 2 week period, at a single point in time, by patients with NTM lung disease (NTMLD) who were currently on any medication to treat their NTMLD versus those not on any therapies. METHODS: We analyzed responses to a "Burden of NTM Survey" developed by the COPD Foundation. The study population included 266 individuals with NTMLD. Using adjusted penalized logistic regression models, we determined associations between the self-reported symptoms and the use of any medication to treat NTMLD. RESULTS: Based on available data, most respondents were aged 50 and older (95.1%), of female gender (93.1%), and had been living with NTMLD for more than 5 years (55.7%). Many respondents reported symptoms that bother them very often or daily. After adjustment for age and gender, duration of living with NTMLD, and other respiratory illnesses, patients on medication had significantly larger odds of reporting difficulty in walking 500 meters without stopping, difficulty in interacting with others, fatigue or lack of energy, feelings of sadness or depression related to illness, and shortness of breath, wheezing or other difficulties. CONCLUSION: In this study, patients currently on any medication to treat their NTMLD reported more symptoms associated with their NTMLD. Further investigations are needed to explore whether increased symptoms are related to differences in disease severity and/or medication effects.
RESUMO
RATIONALE: Non-cystic fibrosis bronchiectasis (NCFB) is characterized by dilated bronchi, poor mucus clearance and susceptibility to bacterial infection. Pseudomonas aeruginosa (PA) is one of the most frequently isolated pathogens in patients with NCFB. The purpose of this study was to evaluate the association between presence of PA and disease severity in patients within the US Bronchiectasis and Nontuberculous mycobacteria (NTM) Research Registry (BRR). METHODS: Baseline US BRR data from adult patients with NCFB collected between 2008 and 2018 was used for this study. The presence of PA was defined as one or more positive PA cultures within two years prior to enrollment. Modified Bronchiectasis Severity Index (m-BSI) and modified FACED (m-FACED) were computed to evaluate severity of bronchiectasis. Unadjusted and multivariable multinomial regression models were used to assess the association between presence of PA and severity of bronchiectasis. RESULTS: Average age of the study participants (n = 1831) was 63.7 years (SD = 14.1), 91.5% white, and 78.8% female. Presence of PA was identified in 25.4% of the patients. Patients with presence of PA had significantly lower mean pre-bronchodilator FEV1% predicted compared to those without PA (62.8% vs. 73.7%, p < .0001). In multivariate analyses, patients with presence of PA had significantly greater odds for having high (ORadj = 6.15 (95%CI:3.98-9.50) and intermediate (ORadj = 2.06 (95%CI:1.37-3.09) severity vs. low severity on m-BSI. CONCLUSION: The presence of PA is common in patients with NCFB within the Bronchiectasis and NTM Research Registry. Severity of bronchiectasis is significantly greater in patients with PA which emphasizes high burden of the disease.
