Role of the Pyrin Inflammasome in Resistance to Yersinia Pestis: A Possible Selective Advantage for Carriers of MEFV Mutations
Background/Purpose: Mutations in MEFV, encoding pyrin, cause the prototypic autoinflammatory disease, familial Mediterranean fever (FMF). The carrier frequency of FMF-associated MEFV mutations is extraordinarily high…Abstract Number: 943 • 2017 ACR/ARHP Annual Meeting
The Course of the Forced Vital Capacity during Treatment for Systemic Sclerosis-Related Interstitial Lung Disease Predicts Long-Term Survival in 2 Independent Cohorts
Background/Purpose: While prior observational studies have identified predictors of mortality in systemic sclerosis-interstitial lung disease (SSc-ILD), no studies have evaluated predictors of long-term mortality in…Abstract Number: 944 • 2017 ACR/ARHP Annual Meeting
Long-Term Survival and Follow-up of Anti-Th/to Antibody Positive Systemic Sclerosis Patients
Background/Purpose: Anti-Th/To antibody is an autoantibody associated with systemic sclerosis (SSc), occurring in 5-10% of patients. To date, only relatively small case series have described…Abstract Number: 945 • 2017 ACR/ARHP Annual Meeting
Autoantibodies to the hPOP1 and Rpp25/38 Components of the Th/to Complex Identify a Subgroup of Systemic Sclerosis (SSc) Associated Interstitial Lung Disease (ILD) and Antibodies to hPOP1 Are Associated with Reduced Survival
Background/Purpose: The clinical associations of anti-Th/To antibodies (Abs) are not fully established, and until recently immunoprecipitation (IP) was the only reliable assay. Using IP, anti-Th/To…Abstract Number: 946 • 2017 ACR/ARHP Annual Meeting
Clinical and Serological Features of Systemic Sclerosis in a Multicenter African American Cohort: Analysis of the Genome Research in African American Scleroderma Patients Clinical Database

Application of a Diagnostic Algorithm to Identify Inflammatory Myopathy in Systemic Sclerosis
Background/Purpose: Muscle involvement in systemic sclerosis (SSc) is under-recognised and poorly understood. Reported prevalence varies up to 15%, reflecting lack of consistent definition, the heterogeneous…Abstract Number: 949 • 2017 ACR/ARHP Annual Meeting
Sequence Homology and Immune Reactivity between T Cell Epitopes of Related Gut Microbes and Two Novel Autoantigens Provide a Link between Microbial and Host Immunity in Patients with Rheumatoid Arthritis
