Prevalence of SSc-ILD

Interstitial lung disease (ILD) is an early and common manifestation of systemic sclerosis (SSc)1,2

ILD OCCURS IN 42%–50% OF SSc PATIENTS3,4

Prevalence of ILD in SSc subtypes2

~53% of patients with diffused cutaneous SSC

ILD OFTEN DEVELOPS EARLY IN THE COURSE OF SSc1,5–7

The risk of developing ILD is greatest early in the disease course of SSc.6 In some patients the first clinical symptom of SSc is directly related to ILD.7,8 ILD can develop within a year after onset of Raynaud’s phenomenon.1

ILD often develops early in the course of SSc1

Of the 695 SSc patients who had a baseline visit within 1 year after Raynaud's phenomenon onset, 31% of patients had FVC <80% predicted and 65% had DLCO <80% predicted.1

Patients with development ILD is highest in the first year following onset of Raynaud’s phenomenon

OLDER AGE, MALE SEX AND AFRICAN ETHNICITY ARE SOME OF THE KEY FACTORS THAT INCREASE THE LIKELIHOOD OF DEVELOPING ILD IN PATIENTS WITH SSc5,8

A mean age at diagnosis of SSc-ILD has been reported as 54.5 years.9Despite the strong female predominance reported in SSc (female-to-male ratio 4.7:1), ILD is more likely to develop in men with SSc.7 Presence of dcSSc is also risk factor for development of ILD.8
