Abstract

Background: Given the phenotypic similarities between rheumatoid arthritis (RA)-associated interstitial lung disease (ILD) (hereafter, RA-ILD) and idiopathic pulmonary fibrosis, we hypothesized that the strongest risk factor for the development of idiopathic pulmonary fibrosis, the gain-of-function MUC5B promoter variant rs35705950, would also contribute to the risk of ILD among patients with RA.

Methods: Using a discovery population and multiple validation populations, we tested the association of the MUC5B promoter variant rs35705950 in 620 patients with RA-ILD, 614 patients with RA without ILD, and 5448 unaffected controls.

Results: Analysis of the discovery population revealed an association of the minor allele of the MUC5B promoter variant with RA-ILD when patients with RA-ILD were compared with unaffected controls (adjusted odds ratio, 3.8; 95% confidence interval [CI], 2.8 to 5.2; P=9.7×10-17). The MUC5B promoter variant was also significantly overrepresented among patients with RA-ILD, as compared with unaffected controls, in an analysis of the multiethnic case series (adjusted odds ratio, 5.5; 95% CI, 4.2 to 7.3; P=4.7×10-35) and in a combined analysis of the discovery population and the multiethnic case series (adjusted odds ratio, 4.7; 95% CI, 3.9 to 5.8; P=1.3×10-49). In addition, the MUC5B promoter variant was associated with an increased risk of ILD among patients with RA (adjusted odds ratio in combined analysis, 3.1; 95% CI, 1.8 to 5.4; P=7.4×10-5), particularly among those with evidence of usual interstitial pneumonia on high-resolution computed tomography (adjusted odds ratio in combined analysis, 6.1; 95% CI, 2.9 to 13.1; P=2.5×10-6). However, no significant association with the MUC5B promoter variant was observed for the diagnosis of RA alone.

Conclusions: We found that the MUC5B promoter variant was associated with RA-ILD and more specifically associated with evidence of usual interstitial pneumonia on imaging. (Funded by Société Française de Rhumatologie and others.).

Figure 1.. Association of the MUC5B rs35705950 Promoter Variant with Rheumatoid Arthritis (RA)–Associated Interstitial Lung Disease (ILD) (RA-ILD).
Shown are forest plots of odds ratios and 95% confidence intervals. The boxes indicate odds ratios, and the horizontal lines indicate 95% confidence intervals for the best-fitting genetic model (dominant or additive) for each association test. The black dashed line represents a mean odds ratio value of 1. The red boxes and red lines indicate the overall odds ratios and 95% confidence intervals, respectively. The case series from France represents the discovery population. For comparisons between patients with RA and controls, the associations were adjusted for the country of origin and sex. For comparisons among patients with RA, the associations were adjusted for the country of origin, sex, age at inclusion, and smoking status. Panel A shows a lack of association of the MUC5B promoter variant rs35705950 with RA without ILD. Panel B shows an additive genotypic association of the MUC5B promoter variant rs35705950 with RA-ILD. The red dashed line represents the mean overall odds ratio value. In Panels A and B, United States–1 indicates one of two case series from the United States. Panel C shows a dominant genotypic association of the MUC5B promoter variant rs35705950 with ILD among patients with RA and those with a pattern of usual interstitial pneumonia (UIP) or possible UIP. RA-UIP denotes RA-ILD and a UIP or possible UIP pattern, and RA-nonUIP denotes RA-ILD and a pattern inconsistent with UIP.

Figure 2.. MUC5B Expression in Explanted Lung Tissue from Patients with RA-ILD and an Unaffected Control.
Shown are representative lung-tissue images from an unaffected control with a GG genotype (Panel A), a patient with RA-ILD and a GG genotype (Panel B), and a patient with RA-ILD and a GT genotype (Panel C). Panel A includes a low-power view (left) of normal lung, top and middle insets with a high-power view of bronchiole with MUC5B staining, and a bottom inset with a high-power view of alveolar epithelia. Panels B and C each include a low-power view (left) of the UIP pattern in explanted lung tissue, a top inset with a high-power view of bronchiole with MUC5B staining, and middle and bottom insets with a high-power view of MUC5B staining in metaplastic epithelia lining honeycomb cysts and MUC5B staining of mucus in honeycomb cysts.
