Comorbidity burden is an important prognostic indicator in various rheumatic and interstitial lung diseases, but few studies have commented on comorbidities in this population. This study was conducted to evaluate the association of individual comorbidities, the Charlson Comorbidity Index (CCI), and the Rheumatic Disease Comorbidity Index (RDCI) with lung disease progression and transplant/mortality outcomes in patients with IPAF. Methods In a retrospective study, we evaluated the prevalence and severity of comorbidities in an institutional cohort of patients with IPAF. Using Cox regression, we correlated the association of individual comorbidities and comorbidity burden using CCI and RDCI with time to lung disease progression (defined as relative forced vital capacity (FVC) decline of 10% or more) and with time to lung transplant/all-cause mortality. We compared the performance of CCI and RDCI, while adjusting for the Interstitial Lung Disease Gender-Age-Physiology (ILD-GAP) index. Results In a sample of 201 individuals with IPAF, a history of cerebrovascular accident (CVA) or cardiovascular disease (CVD), moderate to severe chronic kidney disease, or fracture was associated with a faster onset of lung disease progression, while a history of gastroesophageal reflux was protective. History of CVA/CVD, diabetes mellitus, and lymphoma were associated with a faster onset of lung transplant/death. Both CCI and RDCI were significantly associated with shorter time to lung disease progression (hazard ratio [HR] 1.11, 95% confidence interval [CI] 1.04–1.19 and HR 1.12 with 95%CI 1.00-1.26, respectively) and lung transplant/mortality (HR 1.18 [1.07–1.30] and 1.31 [1.10–1.57], respectively). Conclusions CCI and RDCI may be useful tools in assessing prognosis in patients with IPAF in terms of both lung disease progression and mortality. Prospective studies are needed to further evaluate the performance of CCI and RDCI and the impact of optimizing comorbid conditions that may mitigate poor outcomes among patients with IPAF. interstitial lung disease comorbidity index autoimmune disease interstitial pneumonia BACKGROUND Interstitial pneumonia with autoimmune features (IPAF) is a subset of interstitial lung disease (ILD) that manifests with signs and symptoms of autoimmunity while not meeting classification criteria for a defined rheumatic disease (RD) ( 1 ). Multiple studies have examined the clinical characteristics and outcomes of IPAF patients ( 2 – 5 ), while few studies have commented on the presence and prevalence of comorbidities in this population ( 6 ). To our knowledge, no studies have evaluated the effect of comorbidities on lung function decline in IPAF. Comorbidity burden is an important prognostic indicator in various RDs ( 7 – 10 ) and ILD ( 11 , 12 ) and is associated with worse disease activity, physical function, quality of life, refractory treatment, and higher mortality risk ( 7 , 13 , 14 ), emphasizing the need for awareness, screening, and optimization of comorbid conditions. Composite scoring systems or indices can be used to quantify the total burden of comorbid illnesses to measure the overall burden and impact of comorbidities more accurately and to assess prognosis ( 15 ) Charlson Comorbidity Index (CCI), a summed score of 19 comorbidities weighted according to severity, was developed to predict one-year mortality in hospitalized patients. The CCI can predict various patient outcomes, including in-hospital mortality, length of hospital stays, readmission rates, functional decline, and healthcare utilization ( 14 , 16 ). CCI is also a strong prognostic predictor in ILD with the frequency of 3-year ILD-related events increasing with increasing CCI; however, IPAF patients were not included in this cohort ( 16 ). In addition, CCI does not account for common comorbidities seen in RDs such as hypertension, osteoporosis, obstructive sleep apnea, or depression which can significantly impact disease activity and quality of life ( 7 , 14 ). The rheumatic disease comorbidity index (RDCI) is comprised of 11 comorbid conditions and was developed based on self-report assessments from patients with RDs ( 15 , 17 ). It has performed well in predicting both physical disability and mortality in diseases such as rheumatoid arthritis and gout ( 15 , 18 ). However, its usefulness in presumably autoimmune ILD, such as IPAF, has not been evaluated. The Gender-Age-Physiology (GAP) index was developed as a multidimensional prognostic staging system for ILD using four variables including gender (G), age (A), and two lung physiology variables (P) - forced vital capacity (FVC) and diffusing capacity for carbon monoxide (DLCO) ( 19 ). Although initially validated in patients with idiopathic pulmonary fibrosis (IPF), the GAP model has also accurately predicted the risk of death in chronic non-IPF ILD ( 20 – 22 ). A modified GAP index, known as the ILD-GAP index, includes a disease subtype variable that accounts for better-adjusted survival in ILD subtypes, including RD-associated ILD, chronic hypersensitivity pneumonitis, and idiopathic nonspecific interstitial pneumonia. The ILD-GAP model has predicted mortality in major chronic ILD subtypes across all stages of disease ( 21 ). However, ILD-GAP does not consider the presence or severity of comorbidities, and a recent study demonstrated that the combination of ILD-GAP and CCI performs better in predicting outcomes in ILD than ILD-GAP or CCI alone ( 23 ). Few studies have examined comorbidities ( 24 – 26 ) and no studies have evaluated the association or effect of comorbidities, using indices such as the CCI or RDCI, with outcomes in IPAF. This study was conducted to determine the prevalence and type of comorbidities in an institutional cohort of patients with IPAF; to evaluate the effect of baseline comorbidities on lung disease progression and mortality; and to assess the performance of the CCI and RDCI, while adjusting for the ILD-GAP index, in predicting outcomes in IPAF patients. METHODS Cohort Assembly : This single-center retrospective medical records review study was performed at the University of Texas Southwestern (UTSW) Medical Center. Patients seen in the UTSW Interstitial Lung Disease Clinic between January 2005 and August 2019 who met the European Respiratory Society (ERS)/American Thoracic Society (ATS) classification criteria for IPAF were included ( 1 ). Date of entry into the cohort was considered as the first available pulmonary function test (PFT) date. The UTSW Medical Center Institutional Review Board approved the study prior to the initiation of data extraction (IRB #STU-2019-0913). Patient consent was not obtained for this retrospective medical records review study. Inclusion/Exclusion Criteria : All patients meeting 2015 ERS/ATS IPAF classification criteria were included for evaluation of prevalence of comorbidities and other baseline characteristics. Patients were excluded from primary outcome evaluation if they did not have at least two sets of PFT data and excluded from secondary outcome evaluation if they had less than two visits recorded in the medical record. Baseline characteristics : Demographic data included age at ILD diagnosis, sex, race, ethnicity, and smoking status. ILD diagnosis date was the time point at which ILD was first observed on imaging. Sex, race, and ethnicity data was recorded as documented in the electronic medical record (EMR). Smoking status was assigned as smoker if the patient ever smoked and otherwise as never smoker. Imaging features including lung lesion pattern, presence of honeycombing, and air trapping, were assigned by a pulmonologist (TAN) based on high-resolution computed tomography scans (HRCT) of the chest. The presence of a usual interstitial pneumonia (UIP) pattern on imaging was documented, given the correlation of UIP with increased mortality and faster lung function decline in prior studies ( 3 , 27 ). Comorbidities : Patient medical records were reviewed by an internal medicine physician (MAG) and rheumatologist (EKJ) using a standardized data extraction worksheet. Comorbidities were evaluated by searching for the key terms and reviewing pertinent documentation (including progress notes), laboratory values, and imaging at the time of entry into the cohort (defined as the date of the first PFTs recorded at the initial ILD clinic visit) (Supplementary Appendix A). Agreement between the reviewers was assessed after reviewing 50 charts to ensure accuracy. Calculation of Comorbidity Indices and ILD Severity : CCI and RDCI were calculated according to standardized procedures and a data extraction worksheet (Supplementary Tables 1 and 2) ( 15 , 28 ). The ILD-GAP index (Supplementary Table 3) was calculated using five predictor variables (gender, age, FVC, DLCO, and ILD category) with assigned points to obtain a total score from 0 to 8 ( 21 ). Since IPAF, by definition, is unclassified ILD due to lack of definable etiology such as RD ( 29 ), 0 points were assigned for the ILD category score for each patient in the cohort. Pulmonary Function Tests : PFT data included FVC, forced expiratory volume in one second (FEV1), FEV1/FVC ratio, and DLCO as percentages of predicted values. Baseline PFTs were the first available tests recorded at the first ILD clinic visit. All available additional PFT data were collected. If a patient underwent a lung transplantation, the last PFT data prior to transplant was included. Outcomes : The primary outcome was the time to lung disease progression, defined as relative %FVC decline of ≥ 10% after date of cohort entry. Secondary outcomes were the time to lung transplant and all-cause mortality (whichever occurred first) from the time point of entry into the cohort. All outcomes were obtained from chart review. Statistical Analysis Descriptive statistics were used to calculate the prevalence of baseline characteristics and comorbidities in our IPAF cohort. Continuous and categorical variables were expressed as means with standard deviation and counts with percentages, respectively. We used Cox proportional hazards to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) for each outcome, first in an unadjusted model then adjusted for ILD-GAP and presence of UIP. All analyses were completed in Stata (V.17, College Station, TX). RESULTS Baseline Characteristics: The cohort, comprised of 201 patients meeting the 2015 ERS/ATS IPAF criteria, was predominantly female (76.1%), with a mean age at the time of initial PFTs of 61.8 ± 12.4 years, and an average time of follow-up of 5.6 ± 3.7 years (Table 1 ). White patients represented 69.6% of the cohort and 84.6% of patients were non-Hispanic and 34.5% were former or current smokers. The baseline mean %FVC was 64.7% ± 19.1% of predicted. The mean %DLCO was 45.8% ± 20.3% of predicted. The mean baseline ILD-GAP index in our cohort was 3.2 ± 1.7 points. Forty-eight (23.9%) patients had a UIP pattern on imaging with 46.8% having unexplained air trapping and 21.4% having honeycombing on HRCT.

Table 1 included on the bottom of the file Prevalence of Comorbidities: The prevalence of individual comorbidities is shown in Table 2 . The most prevalent comorbidities in our cohort included hypertension (67.7%) and gastroesophageal reflux disease (GERD) (64.7%). More than 20% of the cohort had chronic obstructive pulmonary disease (COPD), depression, and diabetes mellitus (DM). The average baseline CCI and RDCI were 3.2 (± 2.4) and 3.7 (± 1.3), respectively (Table 1 ).

Of the 191 patients, 104 (54.5%) patients progressed over an average of 2.2 ± 2.0 years. In univariable analysis, older age, being of race other than Asian, history of cerebrovascular accident (CVA) and/or cardiovascular disease (CVD), moderate to severe chronic kidney disease (CKD), and fracture were significantly associated with faster onset of lung disease progression. The presence of honeycombing and GERD were associated with delayed onset of lung disease progression. These associations remained significant when adjusted for ILD-GAP and UIP (Table 3 ).

One patient was lost to follow-up after one visit. Forty-eight (23.9%) patients died and 15 (7.5%) patients had lung transplant (Table 1 ). Older age, male sex, smoking history, lower FVC or DLCO, presence of UIP pattern, and history of CVA and/or CVD, DM (in particular with end-organ damage), and lymphoma were associated with significantly shorter time to lung transplant/death. After adjusting for ILD-GAP, age, UIP pattern on HRCT, DM, and lymphoma remained significantly associated with shorter time to lung transplant/death. After adjusting for the presence of UIP pattern, older age, male sex, smoking history, lower PFT parameters, congestive heart failure (CHF), DM, and lymphoma were significant factors associated with the outcome. Interestingly, only DM with end organ damage and lymphoma remained significantly associated with lung transplant/death after adjusting for both ILD-GAP and UIP (Table 4 ).

ILD-GAP was significantly associated with lung transplant/mortality but not with lung disease progression (Tables 3 and 4 ). The association of CCI with lung disease progression, but not that of RDCI, remained significant when adjusted for ILD-GAP and ILD-GAP and UIP. When adjusted for the presence or absence of UIP pattern alone, both CCI and RDCI remained significant predictors of the outcome (Table 3 ). CCI and RDCI were significantly associated with shorter time to lung transplant/death even when adjusted for ILD-GAP or UIP. However, neither CCI nor RDCI were significantly associated with the lung transplant/mortality outcome after adjusting for both ILD-GAP and UIP pattern in multivariable analysis. Higher ILD-GAP was associated with significantly shorter time to lung transplant/death outcomes in univariable analysis and when adjusted for UIP (Table 4 ). DISCUSSION In this study we explored the prevalence and the effect of baseline comorbidities on lung disease progression and lung transplant/mortality in a cohort of patients with IPAF. We also assessed the performance of two well-established comorbidity indices, CCI and RDCI, in predicting outcomes in this population. We found that comorbidity indices provide comprehensive information regarding a patient’s prognosis, including lung disease progression. Hypertension and GERD were the most prevalent comorbidities in our cohort. This was consistent with a study by Oldham, et al., where GERD was the most prevalent (52.8%) comorbidity in an IPAF cohort raising suspicion for a potential contribution of GERD to disease pathogenesis in IPAF ( 3 ). In addition, COPD, depression, and DM were found to be common comorbid conditions in our cohort, a finding which was not discussed in prior IPAF literature but has been demonstrated in other forms of ILD ( 12 , 30 , 31 ). When evaluating the effect of comorbidities on lung disease progression, this study revealed that multiple comorbidities such as a history of CVA/CVD, moderate to severe CKD and fracture, specifically that of lower extremity or vertebrae, were associated with a faster onset of relative FVC decline of ≥ 10% or more from the time of cohort entry in patients with IPAF. Conversely, a history of GERD was associated with a longer time to lung disease progression. Although it is difficult to ascertain the association between the various comorbidities, prior studies have commented on the effects of these comorbidities on lung disease progression in patients with other forms of ILD. For example, CVD is a treatable comorbidity frequently observed in IPF and has been linked to worse outcomes, with proposed mechanisms including systemic inflammation, hypercoagulability, platelet activation, and oxidative stress ( 32 – 34 ). A complex relationship between CKD and lung disease progression, particularly through alterations of fluid homeostasis and acid-base balance, has also been demonstrated ( 35 , 36 ). A potential explanation for the observed association of fracture and lung disease progression, in this study, is the increased prevalence of steroid use in patients with more severe disease which can thereby increase fracture risk. However, fracture was a baseline comorbidity in the cohort and thus steroid use would not be expected to contribute significantly to its prevalence at the time of baseline data collection. To evaluate this possibility, data regarding osteoporosis was also collected, but did not demonstrate a significant association with the studied outcomes. In other autoimmune diseases, such as rheumatoid arthritis, osteopenia and osteoporosis have correlated with higher mortality and fracture risk, when compared to the general population ( 18 ). Interestingly, GERD was found to be a protective factor for lung disease progression in our cohort, a finding which varies from prior studies that considered GERD to be a risk factor for ILD development ( 37 ). One consideration is the high prevalence of proton pump inhibitor use, an intervention hypothesized to slow lung disease progression in patients with IPF ( 38 , 39 ). Based on our results, the association of CVD, CKD, fracture risk, and GERD with lung disease progression in patients with IPAF warrants further investigation. Importantly, few prior studies have explored the prognostic impact of comorbid conditions in IPAF. Two studies suggested that hypothyroidism was associated with greater mortality ( 7 , 8 ), but a diagnosis of obstructive sleep apnea (OSA) was correlated with better survival when compared to IPAF patients without these conditions ( 7 ). Malignancy was noted to be a serious comorbidity associated with faster progression of fibrotic lung disease in RD-ILD and IPAF ( 9 ). In our study, OSA and hypothyroidism were not significantly associated with outcomes, but lymphoma, as well as CKD and DM, were associated with shorter time to lung transplant/mortality. Similar to other studies, increasing age, male sex, and smoking history were also associated with shorter time to lung transplant/mortality in our cohort ( 40 – 44 ). We evaluated the performance of the CCI and RDCI in patients with IPAF and found that both CCI and RDCI were helpful in predicting lung function and transplant/mortality outcomes, even after adjusting for UIP pattern. However, the performance of indices was variable for both outcomes when adjusted for both ILD-GAP and UIP pattern. Notably, CVA/CVD and fracture, which are components of RDCI, but not CCI, were important comorbidities associated with poor outcomes in our study. Additionally, depression was highly prevalent in our cohort but is only reflected within the RDCI score. These findings suggest that both CCI and RDCI may be useful tools for prognosticating outcomes in IPAF patients. Our study has several strengths. We had a large, diverse IPAF cohort and the ability to explore numerous comorbidities. Sixteen percent of our cohort included Black patients, increasing the external validity of our findings. Comorbidities have been variably explored in cohorts of patients with IPAF, resulting in highly heterogeneous data of the prevalence of multiple comorbidities. In our study, we systematically and rigorously assessed the comorbidities used to calculate two commonly used comorbidity indices, particularly in autoimmune diseases, making our findings relevant to presumably autoimmune-related ILD such as IPAF. Our study was the first to use comorbidity indices CCI and RDCI to assess the comorbidity burden in this specific population and demonstrate their usefulness in assessing functional and survival outcomes. Specifically, this study supports the use of RDCI in this population, a possible advantage for rheumatologists seeing these patients. Our results also emphasize the need for comprehensive evaluation of IPAF patients and multiple tools for optimal management and monitoring, including HRCT imaging, PFT monitoring, and ILD-GAP and comorbidity assessments. We acknowledge several limitations of our study. Given the retrospective nature of the study, the variables were collected by medical record review which can lead to misclassification bias, attrition bias, and the presence of missing data. We used precise and consistent definitions of the key comorbidities and variables to guide the data collection by two clinical researchers (with familiarity with both the medical record and management of these conditions and comorbidities) to mitigate the effects of misclassification bias and imaging data by an experienced ILD pulmonologist. However, loss to follow-up could have introduced selection bias. Patients who did not have repeat PFT data were excluded from the study, which could have been due to unknown death or a different cause that was not recorded in the medical record. Finally, while our study emphasizes the need for comorbidity screening for patients with IPAF, we were unable to evaluate whether controlling comorbidities would mitigate the often detrimental association with disease outcomes. CONCLUSION In summary, our study addresses a substantial healthcare gap for patients with IPAF, as few studies have examined comorbidities in this population. Multiple comorbidities are highly prevalent in IPAF and their burden, as assessed by comorbidity indices, influences functional and survival outcomes. Importantly, our study highlights the utility of two common comorbidity indices in assessing the outcomes of patients with IPAF. Particularly, the comorbidity burden in IPAF may be slightly better assessed by RDCI than CCI due to the inclusion of fracture and depression. Importantly, several of the comorbidities frequently seen in our cohort are modifiable and can be optimized, including DM, depression, COPD, GERD and others. Furthermore, potential mechanisms underlying CVA/CVD, CKD, and fracture with lung disease progression in IPAF need to be explored. Further prospective studies are needed to investigate whether aggressive treatment of comorbidities will mitigate poor outcomes. Clinicians taking care of patients with IPAF should be aware of common comorbid conditions, the potential prognostic implications of comorbidity indices, and the increased morbidity effect of specific comorbidities in this patient population.

Multiple studies have examined the clinical characteristics and outcomes of IPAF patients (\u003cspan additionalcitationids=\"CR3 CR4\" citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e), while few studies have commented on the presence and prevalence of comorbidities in this population (\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e). To our knowledge, no studies have evaluated the effect of comorbidities on lung function decline in IPAF. Comorbidity burden is an important prognostic indicator in various RDs (\u003cspan additionalcitationids=\"CR8 CR9\" citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e) and ILD (\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e, \u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e) and is associated with worse disease activity, physical function, quality of life, refractory treatment, and higher mortality risk (\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e, \u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e, \u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e), emphasizing the need for awareness, screening, and optimization of comorbid conditions.\u003c/p\u003e \u003cp\u003eComposite scoring systems or indices can be used to quantify the total burden of comorbid illnesses to measure the overall burden and impact of comorbidities more accurately and to assess prognosis (\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e) Charlson Comorbidity Index (CCI), a summed score of 19 comorbidities weighted according to severity, was developed to predict one-year mortality in hospitalized patients. The CCI can predict various patient outcomes, including in-hospital mortality, length of hospital stays, readmission rates, functional decline, and healthcare utilization (\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e, \u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e). CCI is also a strong prognostic predictor in ILD with the frequency of 3-year ILD-related events increasing with increasing CCI; however, IPAF patients were not included in this cohort (\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e). In addition, CCI does not account for common comorbidities seen in RDs such as hypertension, osteoporosis, obstructive sleep apnea, or depression which can significantly impact disease activity and quality of life (\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e, \u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eThe rheumatic disease comorbidity index (RDCI) is comprised of 11 comorbid conditions and was developed based on self-report assessments from patients with RDs (\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e, \u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e). It has performed well in predicting both physical disability and mortality in diseases such as rheumatoid arthritis and gout (\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e, \u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e). However, its usefulness in presumably autoimmune ILD, such as IPAF, has not been evaluated.\u003c/p\u003e \u003cp\u003eThe Gender-Age-Physiology (GAP) index was developed as a multidimensional prognostic staging system for ILD using four variables including gender (G), age (A), and two lung physiology variables (P) - forced vital capacity (FVC) and diffusing capacity for carbon monoxide (DLCO) (\u003cspan citationid=\"CR19\" class=\"CitationRef\"\u003e19\u003c/span\u003e). Although initially validated in patients with idiopathic pulmonary fibrosis (IPF), the GAP model has also accurately predicted the risk of death in chronic non-IPF ILD (\u003cspan additionalcitationids=\"CR21\" citationid=\"CR20\" class=\"CitationRef\"\u003e20\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR22\" class=\"CitationRef\"\u003e22\u003c/span\u003e). A modified GAP index, known as the ILD-GAP index, includes a disease subtype variable that accounts for better-adjusted survival in ILD subtypes, including RD-associated ILD, chronic hypersensitivity pneumonitis, and idiopathic nonspecific interstitial pneumonia. The ILD-GAP model has predicted mortality in major chronic ILD subtypes across all stages of disease (\u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e21\u003c/span\u003e). However, ILD-GAP does not consider the presence or severity of comorbidities, and a recent study demonstrated that the combination of ILD-GAP and CCI performs better in predicting outcomes in ILD than ILD-GAP or CCI alone (\u003cspan citationid=\"CR23\" class=\"CitationRef\"\u003e23\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eFew studies have examined comorbidities (\u003cspan additionalcitationids=\"CR25\" citationid=\"CR24\" class=\"CitationRef\"\u003e24\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR26\" class=\"CitationRef\"\u003e26\u003c/span\u003e) and no studies have evaluated the association or effect of comorbidities, using indices such as the CCI or RDCI, with outcomes in IPAF. This study was conducted to determine the prevalence and type of comorbidities in an institutional cohort of patients with IPAF; to evaluate the effect of baseline comorbidities on lung disease progression and mortality; and to assess the performance of the CCI and RDCI, while adjusting for the ILD-GAP index, in predicting outcomes in IPAF patients.\u003c/p\u003e"},{"header":"METHODS","content":"\u003cdiv id=\"Sec3\" class=\"Section2\"\u003e \u003ch2\u003e\u003cspan type=\"Underline\" class=\"Underline\" name=\"Emphasis\"\u003eCohort Assembly\u003c/span\u003e:\u003c/h2\u003e \u003cp\u003e This single-center retrospective medical records review study was performed at the University of Texas Southwestern (UTSW) Medical Center.

In univariable analysis, older age, being of race other than Asian, history of cerebrovascular accident (CVA) and/or cardiovascular disease (CVD), moderate to severe chronic kidney disease (CKD), and fracture were significantly associated with faster onset of lung disease progression. The presence of honeycombing and GERD were associated with delayed onset of lung disease progression.

One patient was lost to follow-up after one visit. Forty-eight (23.9%) patients died and 15 (7.5%) patients had lung transplant (Table\u0026nbsp;\u003cspan refid=\"Tab1\" class=\"InternalRef\"\u003e1\u003c/span\u003e). Older age, male sex, smoking history, lower FVC or DLCO, presence of UIP pattern, and history of CVA and/or CVD, DM (in particular with end-organ damage), and lymphoma were associated with significantly shorter time to lung transplant/death. After adjusting for ILD-GAP, age, UIP pattern on HRCT, DM, and lymphoma remained significantly associated with shorter time to lung transplant/death. After adjusting for the presence of UIP pattern, older age, male sex, smoking history, lower PFT parameters, congestive heart failure (CHF), DM, and lymphoma were significant factors associated with the outcome. Interestingly, only DM with end organ damage and lymphoma remained significantly associated with lung transplant/death after adjusting for both ILD-GAP and UIP (Table\u0026nbsp;\u003cspan

We also assessed the performance of two well-established comorbidity indices, CCI and RDCI, in predicting outcomes in this population. We found that comorbidity indices provide comprehensive information regarding a patient\u0026rsquo;s prognosis, including lung disease progression.\u003c/p\u003e \u003cp\u003eHypertension and GERD were the most prevalent comorbidities in our cohort. This was consistent with a study by Oldham, et al., where GERD was the most prevalent (52.8%) comorbidity in an IPAF cohort raising suspicion for a potential contribution of GERD to disease pathogenesis in IPAF (\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e). In addition, COPD, depression, and DM were found to be common comorbid conditions in our cohort, a finding which was not discussed in prior IPAF literature but has been demonstrated in other forms of ILD (\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e, \u003cspan citationid=\"CR30\" class=\"CitationRef\"\u003e30\u003c/span\u003e, \u003cspan citationid=\"CR31\" class=\"CitationRef\"\u003e31\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eWhen evaluating the effect of comorbidities on lung disease progression, this study revealed that multiple comorbidities such as a history of CVA/CVD, moderate to severe CKD and fracture, specifically that of lower extremity or vertebrae, were associated with a faster onset of relative FVC decline of \u0026ge;\u0026thinsp;10% or more from the time of cohort entry in patients with IPAF. Conversely, a history of GERD was associated with a longer time to lung disease progression.\u003c/p\u003e \u003cp\u003eAlthough it is difficult to ascertain the association between the various comorbidities, prior studies have commented on the effects of these comorbidities on lung disease progression in patients with other forms of ILD. For example, CVD is a treatable comorbidity frequently observed in IPF and has been linked to worse outcomes, with proposed mechanisms including systemic inflammation, hypercoagulability, platelet activation, and oxidative stress (\u003cspan additionalcitationids=\"CR33\" citationid=\"CR32\" class=\"CitationRef\"\u003e32\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR34\" class=\"CitationRef\"\u003e34\u003c/span\u003e). A complex relationship between CKD and lung disease progression, particularly through alterations of fluid homeostasis and acid-base balance, has also been demonstrated (\u003cspan citationid=\"CR35\" class=\"CitationRef\"\u003e35\u003c/span\u003e, \u003cspan citationid=\"CR36\" class=\"CitationRef\"\u003e36\u003c/span\u003e). A potential explanation for the observed association of fracture and lung disease progression, in this study, is the increased prevalence of steroid use in patients with more severe disease which can thereby increase fracture risk. However, fracture was a baseline comorbidity in the cohort and thus steroid use would not be expected to contribute significantly to its prevalence at the time of baseline data collection. To evaluate this possibility, data regarding osteoporosis was also collected, but did not demonstrate a significant association with the studied outcomes. In other autoimmune diseases, such as rheumatoid arthritis, osteopenia and osteoporosis have correlated with higher mortality and fracture risk, when compared to the general population (\u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e). Interestingly, GERD was found to be a protective factor for lung disease progression in our cohort, a finding which varies from prior studies that considered GERD to be a risk factor for ILD development (\u003cspan citationid=\"CR37\" class=\"CitationRef\"\u003e37\u003c/span\u003e). One consideration is the high prevalence of proton pump inhibitor use, an intervention hypothesized to slow lung disease progression in patients with IPF (\u003cspan citationid=\"CR38\" class=\"CitationRef\"\u003e38\u003c/span\u003e, \u003cspan citationid=\"CR39\" class=\"CitationRef\"\u003e39\u003c/span\u003e). Based on our results, the association of CVD, CKD, fracture risk, and GERD with lung disease progression in patients with IPAF warrants further investigation.\u003c/p\u003e \u003cp\u003eImportantly, few prior studies have explored the prognostic impact of comorbid conditions in IPAF. Two studies suggested that hypothyroidism was associated with greater mortality (\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e, \u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e), but a diagnosis of obstructive sleep apnea (OSA) was correlated with better survival when compared to IPAF patients without these conditions (\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e). Malignancy was noted to be a serious comorbidity associated with faster progression of fibrotic lung disease in RD-ILD and IPAF (\u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e). In our study, OSA and hypothyroidism were not significantly associated with outcomes, but lymphoma, as well as CKD and DM, were associated with shorter time to lung transplant/mortality. Similar to other studies, increasing age, male sex, and smoking history were also associated with shorter time to lung transplant/mortality in our cohort (\u003cspan additionalcitationids=\"CR41 CR42 CR43\" citationid=\"CR40\" class=\"CitationRef\"\u003e40\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR44\" class=\"CitationRef\"\u003e44\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eWe evaluated the performance of the CCI and RDCI in patients with IPAF and found that both CCI and RDCI were helpful in predicting lung function and transplant/mortality outcomes, even after adjusting for UIP pattern. However, the performance of indices was variable for both outcomes when adjusted for both ILD-GAP and UIP pattern. Notably, CVA/CVD and fracture, which are components of RDCI, but not CCI, were important comorbidities associated with poor outcomes in our study. Additionally, depression was highly prevalent in our cohort but is only reflected within the RDCI score. These findings suggest that both CCI and RDCI may be useful tools for prognosticating outcomes in IPAF patients.\u003c/p\u003e \u003cp\u003eOur study has several strengths. We had a large, diverse IPAF cohort and the ability to explore numerous comorbidities. Sixteen percent of our cohort included Black patients, increasing the external validity of our findings. Comorbidities have been variably explored in cohorts of patients with IPAF, resulting in highly heterogeneous data of the prevalence of multiple comorbidities. In our study, we systematically and rigorously assessed the comorbidities used to calculate two commonly used comorbidity indices, particularly in autoimmune diseases, making our findings relevant to presumably autoimmune-related ILD such as IPAF. Our study was the first to use comorbidity indices CCI and RDCI to assess the comorbidity burden in this specific population and demonstrate their usefulness in assessing functional and survival outcomes. Specifically, this study supports the use of RDCI in this population, a possible advantage for rheumatologists seeing these patients. Our results also emphasize the need for comprehensive evaluation of IPAF patients and multiple tools for optimal management and monitoring, including HRCT imaging, PFT monitoring, and ILD-GAP and comorbidity assessments.\u003c/p\u003e \u003cp\u003eWe acknowledge several limitations of our study. Given the retrospective nature of the study, the variables were collected by medical record review which can lead to misclassification bias, attrition bias, and the presence of missing data. We used precise and consistent definitions of the key comorbidities and variables to guide the data collection by two clinical researchers (with familiarity with both the medical record and management of these conditions and comorbidities) to mitigate the effects of misclassification bias and imaging data by an experienced ILD pulmonologist. However, loss to follow-up could have introduced selection bias. Patients who did not have repeat PFT data were excluded from the study, which could have been due to unknown death or a different cause that was not recorded in the medical record. Finally, while our study emphasizes the need for comorbidity screening for patients with IPAF, we were unable to evaluate whether controlling comorbidities would mitigate the often detrimental association with disease outcomes.\u003c/p\u003e"},{"header":"CONCLUSION","content":"\u003cp\u003eIn summary, our study addresses a substantial healthcare gap for patients with IPAF, as few studies have examined comorbidities in this population. Multiple comorbidities are highly prevalent in IPAF and their burden, as assessed by comorbidity indices, influences functional and survival outcomes. Importantly, our study highlights the utility of two common comorbidity indices in assessing the outcomes of patients with IPAF. Particularly, the comorbidity burden in IPAF may be slightly better assessed by RDCI than CCI due to the inclusion of fracture and depression. Importantly, several of the comorbidities frequently seen in our cohort are modifiable and can be optimized, including DM, depression, COPD, GERD and others. Furthermore, potential mechanisms underlying CVA/CVD, CKD, and fracture with lung disease progression in IPAF need to be explored. Further prospective studies are needed to investigate whether aggressive treatment of comorbidities will mitigate poor outcomes. Clinicians taking care of patients with IPAF should be aware of common comorbid conditions, the potential prognostic implications of comorbidity indices, and the increased morbidity effect of specific comorbidities in this patient population.\u003c/p\u003e"},{"header":"List Of Abbreviations","content":"\u003cp\u003eIPAF: interstitial pneumonia with autoimmune features\u003c/p\u003e\n\u003cp\u003eILD: interstitial lung disease\u003c/p\u003e\n\u003cp\u003eRD: rheumatic disease\u003c/p\u003e\n\u003cp\u003eCCI: Charlson Comorbidity Index\u003c/p\u003e\n\u003cp\u003eRDCI: rheumatic disease comorbidity index\u003c/p\u003e\n\u003cp\u003eGAP index: Gender-Age-Physiology index\u003c/p\u003e\n\u003cp\u003eFVC: forced vital capacity\u003c/p\u003e\n\u003cp\u003eDLCO: diffusing capacity for carbon monoxide\u003c/p\u003e\n\u003cp\u003eIPF: idiopathic pulmonary fibrosis\u003c/p\u003e\n\u003cp\u003eUTSW: University of Texas Southwestern\u003c/p\u003e\n\u003cp\u003eERS: European Respiratory Society\u003c/p\u003e\n\u003cp\u003eATS: American Thoracic Society\u003c/p\u003e\n\u003cp\u003ePFT: pulmonary function test\u003c/p\u003e\n\u003cp\u003eEMR: electronic medical record\u003c/p\u003e\n\u003cp\u003eHRCT: high-resolution computed tomography\u003c/p\u003e\n\u003cp\u003eUIP: usual interstitial pneumonia\u003c/p\u003e\n\u003cp\u003eFEV1: forced expiratory volume in one second\u003c/p\u003e\n\u003cp\u003eHR: hazard ratio\u003c/p\u003e\n\u003cp\u003eCI: confidence interval\u003c/p\u003e\n\u003cp\u003eGERD: gastroesophageal reflux disease\u003c/p\u003e\n\u003cp\u003eCOPD: chronic obstructive pulmonary disease\u003c/p\u003e\n\u003cp\u003eDM: diabetes mellitus\u003c/p\u003e\n\u003cp\u003eCVA: cerebrovascular accident\u003c/p\u003e\n\u003cp\u003eCVD: cardiovascular disease\u003c/p\u003e\n\u003cp\u003eCKD: chronic kidney disease\u003c/p\u003e\n\u003cp\u003eCHF: congestive heart failure\u003c/p\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eEthics Approval and Consent to Participate\u003c/strong\u003e:\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eThe University of Texas Southwestern Medical Center Institutional Review Board approved the study prior to the initiation of data extraction (IRB #STU-2019-0913).

Comorbidity burden is an important prognostic indicator in various rheumatic and interstitial lung diseases, but few studies have commented on comorbidities in this population. This study was conducted to evaluate the association of individual comorbidities, the Charlson Comorbidity Index (CCI), and the Rheumatic Disease Comorbidity Index (RDCI) with lung disease progression and transplant/mortality outcomes in patients with IPAF.\u003c/p\u003e\u003ch2\u003eMethods\u003c/h2\u003e \u003cp\u003eIn a retrospective study, we evaluated the prevalence and severity of comorbidities in an institutional cohort of patients with IPAF. Using Cox regression, we correlated the association of individual comorbidities and comorbidity burden using CCI and RDCI with time to lung disease progression (defined as relative forced vital capacity (FVC) decline of 10% or more) and with time to lung transplant/all-cause mortality. We compared the performance of CCI and RDCI, while adjusting for the Interstitial Lung Disease Gender-Age-Physiology (ILD-GAP) index.\u003c/p\u003e\u003ch2\u003eResults\u003c/h2\u003e \u003cp\u003eIn a sample of 201 individuals with IPAF, a history of cerebrovascular accident (CVA) or cardiovascular disease (CVD), moderate to severe chronic kidney disease, or fracture was associated with a faster onset of lung disease progression, while a history of gastroesophageal reflux was protective. History of CVA/CVD, diabetes mellitus, and lymphoma were associated with a faster onset of lung transplant/death. Both CCI and RDCI were significantly associated with shorter time to lung disease progression (hazard ratio [HR] 1.11, 95% confidence interval [CI] 1.04\u0026ndash;1.19 and HR 1.12 with 95%CI 1.00-1.26, respectively) and lung transplant/mortality (HR 1.18 [1.07\u0026ndash;1.30] and 1.31 [1.10\u0026ndash;1.57], respectively).\u003c/p\u003e\u003ch2\u003eConclusions\u003c/h2\u003e \u003cp\u003eCCI and RDCI may be useful tools in assessing prognosis in patients with IPAF in terms of both lung disease progression and mortality. Prospective studies are needed to further evaluate the performance of CCI and RDCI and the impact of optimizing comorbid conditions that may mitigate poor outcomes among patients with IPAF.\u003c/p\u003e","manuscriptTitle":"Evaluation of Comorbidity Burden on Disease Progression and Mortality in Patients with Interstitial Pneumonia with Autoimmune Features: a Retrospective Cohort Study","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2023-08-17 05:17:41","doi":"10.21203/rs.3.rs-3210870/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"
