Background/Purpose Immunoglobulin (Ig) G4-related disease (IgG4-RD) is a recently recognized fibro-inflammatory disease with multi-organ system involvement. Affected patients frequently have a history of bronchial asthma and allergic rhinitis. The reported pathogenesis of IgG4-RD describes the clear involvement of excessive Th2 cells and regulatory immune reaction in addition to plasma cells 1). However, peripheral immune cell phenotype, which reflects disease status, has not been comprehensively evaluated. Our aim was to definitively determine peripheral blood cell abnormalities and their correlation with disease activity in patients with IgG4-RD.Methods Peripheral blood samples were obtained from active untreated IgG4-RD patients (n=11) and healthy controls (n=16). Comprehensive immunophenotyping assay with information on activation status was done by multi-color flow cytometry, and the proportion of peripheral blood mononuclear cells (PBMCs), including T cells (naïve/memory, Th1/2/17, Treg, and Tfh), B cells (naïve/memory, plasmablast, Breg), monocytes (classical, intermediate, non-classical) and dendritic cells (myeloid, plasmacytoid), and their activity status were precisely defined. Disease activity was measured using the IgG4-RD responder index (RI). Statistical analysis was done using the Mann-Whitney U test and Spearman rank correlation coefficient test.Results The proportion of plasmablasts (CD19+CD20-CD27+CD38+), memory Th2 cells (CD3+CD4+CXCR3-CCR6-CD45RA-), Tregs (CD3+CD4+CD25+CD127low), Tfh (CD3+CD4+CXCR5+), and mDCs (CD3-CD19-CD14-HLA-DR+CD1c+CD303-) in peripheral blood was significantly increased in IgG4-RD patients compared with HC, whereas the proportion of pDCs (CD3-CD19-CD14-HLA-DR+CD1c-CD303+）was significantly decreased. Interestingly, the proportion of pDCs in total DCs was negatively correlated with IgG4-RD RI (r=-0.778, p=0.005) while the proportion of plasmablasts in CD19+cells was positively correlated with RI (r=0.701, p=0.016). Further, the increased proportion of plasmablasts was positively correlated with serum IgG4 level (r=0.718, p=0.013) while the decreased proportion of pDCs tended to be negatively correlated with the number of affected organs (r=-0.518, p=0.061). Conclusion Our comprehensive analysis identified distinct proportional changes in PBMCs in IgG4-RD. In particular, the decrease in pDCs and increase in plasmablasts were strongly linked with disease activity. These combined measurements are expected to be clinically useful surrogate cell markers. This newly identified decrease in circulating pDCs may be involved in the pathogenesis in IgG4-RD via the recently described role in the enhancement of Th2 response 2).References: 1) Stone JH et.al.

All abstracts accepted to ACR Convergence are under media embargo once the ACR has notified presenters of their abstract’s acceptance. They may be presented at other meetings or published as manuscripts after this time but should not be discussed in non-scholarly venues or outlets. The following embargo policies are strictly enforced by the ACR.

Accepted abstracts are made available to the public online in advance of the meeting and are published in a special online supplement of our scientific journal, Arthritis & Rheumatology. Information contained in those abstracts may not be released until the abstracts appear online. In an exception to the media embargo, academic institutions, private organizations, and companies with products whose value may be influenced by information contained in an abstract may issue a press release to coincide with the availability of an ACR abstract on the ACR website. However, the ACR continues to require that information that goes beyond that contained in the abstract (e.g., discussion of the abstract done as part of editorial news coverage) is under media embargo until 10:00 AM CT on October 25. Journalists with access to embargoed information cannot release articles or editorial news coverage before this time. Editorial news coverage is considered original articles/videos developed by employed journalists to report facts, commentary, and subject matter expert quotes in a narrative form using a variety of sources (e.g., research, announcements, press releases, events, etc.).

Violation of this policy may result in the abstract being withdrawn from the meeting and other measures deemed appropriate. Authors are responsible for notifying colleagues, institutions, communications firms, and all other stakeholders related to the development or promotion of the abstract about this policy. If you have questions about the ACR abstract embargo policy, please contact ACR abstracts staff at [email protected].
