Baseline absolute monocyte count predicts lung function decline among patients with systemic sclerosis-associated interstitial lung disease: A post hoc analysis from the focuSSced trial

Semin Arthritis RheumPublished Secondary analysis of the focuSSced randomised trial

Authors' conclusion

AMC may be a biomarker of disease progression in SSc-ILD, especially in those with early SSc with elevated circulating inflammatory markers.
