IL-33 / ST2 in Rheumatoid Arthritis at the EULAR 2014 Meeting in Paris


A year ago I had written about the potential role of IL-33, a member of the IL-1 family, in rheumatoid arthritis and experimental inflammatory arthritis. Last year it had been shown, that serum IL33 levels are increased especially in anti-CCP positive RA patients. W.D. Xu and colleagues concluded, that “the role of the IL-33/ST2 axis in B-cell immunopathology in RA needs to be further addressed.”
This year J.-J. Kim and colleagues presented the following study [AB0066]: “Clinical usefulness of serum soluble ST2 in rheumatoid arthritis with anti-TNF-α therapy”. Conclusions: “The serum sST2 level was increased in RA patients, and correlated with other inflammatory markers of disease activity. Monitoring of serum sST2 levels may be a possible marker of effectiveness to anti-TNF-α therapy for RA patients, when this is supported by an extended study with more patients.”
So we see further use of IL-33/ST2 as a marker, but we don’t know more about “the role of the IL-33/ST2 axis in B-cell immunopathology in RA”. There were two more studies, one on Sjogren’s syndrome and one on Adult Onset Still’s Disease.
