Outline of Final Research Achievements

The patients with elderly-onset rheumatoid arthritis (RA) can achieve clinical remission and normal physical function by therapeutic strategy targeting low disease activity(T2T). Anti-cyclic citrullinated peptide antibody, bone erosion, high disease activity, and clinical responses at initial treatment are predictors of joint destruction. Serious adverse events under T2T strategy of EORA have great impact on physical dysfunction in patients who achieved treatment goals. Peptidylarginine Deiminase 4 (PAD4) protein expression in peripheral blood is not associated with disease activity. Genome-wide association studies (GWAS) have identified new single nucleotide polymorphisms (SNPs) related to susceptibility of RA. However the SNP cannot predict treatment response of EORA in our prospective cohort. We would like to establish T2T strategy cooperated with SNP related to treatment response and adverse events, but not RA susceptibility.
