In systemic sclerosis (SSc), the frequent involvement of hand and face leads to their disability. We aimed to assess influence of hand and face disability on global disability and Health related Quality of life (HRQoL). ⋯ dSSc patients present higher global and local disability, and lower HRQoL in SPI than lSSc patients. Local disabilities, assessed by CHDFS and MHISS, are independently related to global disability and HRQoL.

Polymyositis/dermatomyositis (PM/DM) is an autoimmune disease characterised by skin and muscle inflammation, internal organ involvement and serum disease-specific autoantibodies. The recently identified anti-MDA5 (melanoma differentiation-associated gene 5) antibodies are associated with clinically amyopathic DM (CADM), rapidly progressive interstitial lung disease, severe skin manifestations, and poor prognosis. Our objective was to examine the clinical significance of anti-MDA5 antibodies in a cohort of European Caucasian patients with PM/DM, considering that data on anti-MDA5 serology are limited to Asian and US cohorts. ⋯ Our study on European patients with PM/DM confirms that anti-MDA5 antibodies are not uncommon. All anti-MDA5 (+) cases are affected by CADM with typical skin disease, while rapidly progressive pulmonary involvement was diagnosed only in one case. Further studies in larger cohorts are necessary to define the clinical significance of anti-MDA5 antibodies in European PM/DM.

We sought to examine the relationship between measures of ILD severity and PH in patients with SSc. ⋯ No association between severity of ILD and cardiac haemodynamic profiles were identified in this cohort. We believe this underscores the complex nature of PH and ILD in individuals with SSc. We do suspect that some individuals with SSc-ILD will also have concomitant pulmonary vascular disease but simple assessments to grade severity of ILD - by PFT or HRCT estimates of ILD extent - are likely not enough to reliably distinguish between PAH versus PH-ILD. Further research into how to distinguish and manage these subsets is warranted.
