ABI-RA
Patients with RA diagnosis according to 2010 ACR/EULAR criteria and who were prescribed for the first time a BP among the TNF inhibitors adalimumab, infliximab (original product or biosimilar), etanercept, the anti-CD20 antibody rituximab, or the anti-IL6R antibody tocilizumab (administered SC or intravenously) as first-line or second-line therapy were recruited from March 3, 2014 to June 21, 2016. Patients who were not naive for the biotherapy they were given in the study were excluded.

Combination of peripheral blood gene expression prof...
Peripheral blood samples were obtained at week 0 and week 4 of tocilizumab treatment and global gene expression profiling identified markers of responder status.

Comparison of human Rheumatoid arthritis patient per...
8 Rheurmatoid arthritis patients have been compared just before and after Leukocytapheresis treatment (overall 16 samples). The Pre-LCAP samples were labeled using Cy5, and the Post-LCAP labeled with Cy3.

Differential effects of TNFalpha and IL1beta on FLS ...
Fibroblast-like cells (FLS) were purified from synovial biopsies from RA patients. Briefly, minced synovial fragments were digested in 1 mg/ml hyaluronidase solution (Sigma Aldrich, St Louis, MO) for 15 minutes at 37°C and 6 mg/ml collagenase type IV (Invitrogen, Paisley, UK) for 2 hours at 37°C. Next, cells were washed, resuspended in high-glucose Dulbecco’s Modified Eagle Medium (Invitrogen) supplemented with 1% antibiotics-antimycotics (Invitrogen) and 1% MEM sodium pyruvate (Invitrogen), ...

Differential expression of rituximab responders vs. ...
We have recruited 9 RA patients starting immunotherapy with rituximab. The same day of the first infusion we obtained the three different cell type samples: whole blood (preserved in PaxGene tubes), B cells (using negative selection) and CD4+ T cells (using negative selection). At week 24 of treatment we determined the clinical response using the RelDas score. All tissue samples were processed in parallel (i.e. RNA extraction and microarray profiling with Illumina WG6 Beadchip) in order to mi...

Differential gene expression in RA synovial biopsies...
All patients had rheumatoid arthritis (RA), according to the American College of rheumatology criteria for the diagnosis of RA. They had active disease at the time of initiation of adalimumab therapy and were resistant to conventional therapy. They all had erosive changes imaged on conventional x-rays of the hands and/or feet. All patients were treated with disease-modifying antirheumatic drugs (DMARD’s), 23 with methotrexate (median dose 15 mg/week, range 7.5 – 20 mg/week), and 2 with leflun...

Early and long-standing rheumatoid arthritis: molecu...
PBMC then RNA were extracted from synovial biopsies of 4 eraly RA patients, 4 long-standing RA patients and from 7 normal synovium used as control. Each sample was hybridized three times in different nylon membrane.

Efficacy of anti-TNF biologic agent, infliximab, for...
Forty-two and 26 consecutive RA patients followed at Saitama Medical Center, for retrospective and verification studies, respectively, who were resistant to standard MTX treatment, were enrolled. The serum CRP level was used for the definition of the level of inflammation of each patient, 0.3 mg/dl or less as “no inflammation” (NI), and more than 0.3 mg/dl as “residual inflammation” (RI) at 14 weeks after the first treatment with infliximab infusion. Differentially expressed genes between the...
