Background and objectiveThe course of systemic sclerosis‐associated interstitial lung disease (SSc‐ILD) is highly variable, and accurate prognostic markers are needed. KL‐6 is a mucin‐like glycoprotein (MUC1) expressed by type II pneumocytes, while CYFRA 21‐1 is expressed by alveolar and bronchiolar epithelial cells. Both are released into the blood from cell injury.MethodsSerum KL‐6 and CYFRA 21‐1 levels were measured in a retrospective (n = 189) and a prospective (n = 118) cohort of SSc patients. Genotyping of MUC1 rs4072037 was performed. Linear mixed‐effect models were used to evaluate the relationship with change in lung function parameters over time, while association with survival was evaluated with Cox proportional hazard analysis.ResultsIn both cohorts, KL‐6 and CYFRA 21‐1 were highest in patients with lung involvement, and in patients with extensive rather than limited ILD. KL‐6 was higher in patients carrying the MUC1 rs4072037 G allele in both cohorts. In patients with SSc‐ILD, serum KL‐6, but not CYFRA 21‐1, was significantly associated with DLCO decline in both cohorts (P = 0.001 and P = 0.004, respectively), and with FVC decline in the retrospective cohort (P = 0.005), but not the prospective cohort. When combining the cohorts and subgrouping by severity (median CPI = 45.97), KL‐6 remained predictive of decline in DLCO in both milder (P = 0.007) and more severe disease (P = 0.02) on multivariable analysis correcting for age, gender, ethnicity, smoking history and MUC1 allele carriage.ConclusionOur results suggest serum KL‐6 predicts decline in lung function in SSc, suggesting its clinical utility in risk stratification for progressive SSc‐ILD.

RATIONALE: Chronic hypersensitivity pneumonitis (CHP) is a condition that arises following repeated exposure and sensitisation to inhaled antigens. The lung microbiome is increasingly implicated in respiratory disease but to date, no study has investigated the composition of microbial communities in the lower airways in CHP. OBJECTIVE: To characterise and compare the airway microbiome in subjects with CHP, idiopathic pulmonary fibrosis (IPF) and controls. METHODS: We prospectively recruited individuals diagnosed with CHP (n=110), IPF (n=45) and controls (n=28). Subjects underwent bronchoalveolar lavage and bacterial DNA was isolated, quantified by qPCR and the 16S rRNA gene was sequenced to characterise the bacterial communities in the lower airways. MAIN MEASUREMENTS AND RESULTS: Distinct differences in the microbial profiles were evident in the lower airways of subjects with CHP and IPF. At the phylum level, the prevailing microbiota of both IPF and CHP subjects included Firmicutes, Bacteroidetes, Proteobacteria and Actinobacteria. However, in IPF, Firmicutes dominated while the percentage of reads assigned to Proteobacteria in the same group was significantly lower compared to CHP subjects. At the genus level, Staphylococcus was increased in CHP and Actinomyces and Veillonella in IPF. The lower airway bacterial burden in CHP subjects was higher than controls but lower than those with IPF. In contrast to IPF, there was no association between bacterial burden and survival in CHP. CONCLUSIONS: The microbial profile of the lower airways in subjects with CHP is distinct from that of IPF and, notably, bacterial burden in individuals with CHP fails to predict survival.

RATIONALE: The impact of COVID-19 on patients with Interstitial Lung Disease (ILD) has not been established. OBJECTIVES: To assess outcomes in patients with ILD hospitalized for COVID-19 versus those without ILD in a contemporaneous age, sex and comorbidity matched population. METHODS: An international multicenter audit of patients with a prior diagnosis of ILD admitted to hospital with COVID-19 between 1 March and 1 May 2020 was undertaken and compared with patients, without ILD obtained from the ISARIC 4C cohort, admitted with COVID-19 over the same period. The primary outcome was survival. Secondary analysis distinguished IPF from non-IPF ILD and used lung function to determine the greatest risks of death. MEASUREMENTS AND MAIN RESULTS: Data from 349 patients with ILD across Europe were included, of whom 161 were admitted to hospital with laboratory or clinical evidence of COVID-19 and eligible for propensity-score matching. Overall mortality was 49% (79/161) in patients with ILD with COVID-19. After matching ILD patients with COVID-19 had higher mortality (HR 1.60, Confidence Intervals 1.17-2.18 p=0.003) compared with age, sex and co-morbidity matched controls without ILD. Patients with a Forced Vital Capacity (FVC) of <80% had an increased risk of death versus patients with FVC ≥80% (HR 1.72, 1.05-2.83). Furthermore, obese patients with ILD had an elevated risk of death (HR 2.27, 1.39-3.71). CONCLUSIONS: Patients with ILD are at increased risk of death from COVID-19, particularly those with poor lung function and obesity. Stringent precautions should be taken to avoid COVID-19 in patients with ILD.

The MUC5B promoter variant rs35705950 is associated with idiopathic pulmonary fibrosis (IPF). MUC5B glycoprotein is overexpressed in IPF lungs. We examined immunohistochemical expression of MUC5B in different interstitial lung disease patterns according to rs35705950 T-allele carriage. We observed increased expression of MUC5B in T-allele carriers in both distal airways and honeycomb cysts in patients with IPF (n=23), but no difference in MUC5B expression according to T-carrier status in the distal airways of patients with idiopathic non-specific interstitial pneumonitis (n=17), in scleroderma-associated non-specific interstitial pneumonitis (n=15) or in control lungs (n=20), suggesting that tissue overexpression in MUC5B rs35705950 T-carriers is specific to IPF.
