Idiopathic inflammatory myopathies (IIM) are a heterogenous group of autoimmune conditions with substantial morbidity. EULAR in collaboration with the American College of Rheumatology (ACR) introduced classification criteria for the major subgroups in 2017,1 but there is a need for contemporary real-world data to understand the burden – and well as new ways of assessing disease activity.

Day two at EULAR 2026 was jammed with sessions on advances in immune checkpoint inhhbitors (and irAEs), Lupus, Scleroderma, RA and IgG4 related disease.  Here are a few of my favorites from Day 2. 

RA-ILD remains one of the most serious extra-articular manifestations of RA, contributing substantially to morbidity and mortality. Two abstracts presented at EULAR 2026 add important insights into identifying patients at risk for RA-ILD and understanding the genetic mechanisms that may underpin disease development.
