CTD-ILD patient cases
Patients like Anne and John have connective tissue disease-associated interstitial lung diseases (CTD-ILDs) that demand vigilanceExplore these patient cases for fibrotic CTD-ILDs and their impact on patients

MEET ANNE*
Anne was diagnosed with rheumatoid arthritis-associated ILD one year ago
Age: 55
Underlying diagnosis: rheumatoid arthritis
Treatment history: DMARD
Pulmonary complications: RA-ILD with UIP pattern on HRCT 1 year ago
Over the past 6 months, Anne’s respiratory symptoms have worsened with coughing that has started to keep her awake most nights1
This recent evidence suggests that Anne has developed a progressive phenotype
“It was a real shock to be diagnosed with RA-ILD. I really feel, ‘Why me?’ I’ve always been so active and now I’ll have to rethink life”
Patients with RA-ILD like Anne are at risk of early death2,3
Patients with RA-ILD who experience a 10% decline in FVC % predicted at any point during follow-up are at increased risk of mortality2
A progressive fibrosing ILD phenotype develops in 40% of patients with RA-ILD4
Delays in the diagnosis of underlying ILD in patients with RA can significantly increase patients’ risk of death – ILD in patients with RA can significantly reduce survival by 7.3 years (p<0.001)3
HOW LONG COULD PATIENTS LIKE ANNE SURVIVE?
Patients with RA-ILD have significantly worse survival than those without ILD3†

RA-ILD patients with UIP on HRCT have a shorter survival time than those with NSIP on HRCT2
Additionally, acute exacerbation of ILD is a serious event for all patients with RA-ILD5,6
17% of patients with RA-ILD experienced acute exacerbation of ILD over 33 months in a retrospective review of 84 patients with RA-ILD5,6
Patients with RA-ILD who experience acute exacerbation of ILD have a high risk of death in the 1.5 months immediately after the event5,6

MEET JOHN*
John was diagnosed with mixed connective tissue
disease-associated ILD three years ago
Age: 44
Underlying diagnosis: mixed connective tissue disease
Pulmonary complications: MCTD-ILD 3 years ago
John has been experiencing increasing levels of dyspnea that have begun to affect his everyday activities7
This recent evidence suggests that John has developed a progressive phenotype
“Having two school-age children means I should be running them round to clubs and activities, but my CTD-ILD means I barely have the energy to play ball games in the park with my children without getting short of breath”
HOW LONG COULD PATIENTS LIKE JOHN SURVIVE?
PATIENTS WITH MCTD-ILD LIKE JOHN ARE AT RISK OF EARLY MORTALITY7
Patients with MCTD-ILD involving ≥5% total lung volume have significantly worse survival than those involving <5% total lung volume7‡
10-year cumulative survival rate for MCTD patients with ILD of ≥10% TLV was 60% (95% CI=29%, 81%)7‡

‡ From a long-term observational study of patients with mixed CTD (N=135) who had HRCT scans at baseline. The study examined the prevalence, extent, progression and functional effect of ILD. 10-year cumulative survival rates were 87% (95% CI=79%, 92%) and 70% (95% CI=49%, 84%) for MCTD patients with ILD of <5% TLV and ≥5% TLV, respectively (p=0.015).
