Quantification of GADD34 Expression in RA

Quantification of GADD34 Expression in Rheumatoid Arthritis

GADD34 gene expression level is quantified in the PBMC by quantitative PCR.

GADD34 transcrit amplification in a sample from a healthy donor and a sample from a patient was measured 25 times in the same experiment in order to assess repeatability and in triplicate in each qPCR experiment (at least 7) in order to assess reproducibility.

GADD34 gene expression level was quantified in the PBMC of the three groups of patients and compared between the three groups.

In patients treated with therapeutical arthrocentesis, to compare GADD34 gene expression level in synovial cells compared with its level in PBMC.

Ankylosing Spondylitis

Patients with Ankylosing spondylitis naive to TNF-blockers, before the first TNF-block administration

Ankylosing Spondylitis Baseline for TNF Blocker

Ankylosing spondylitis recruited after a minimum of 6 months after the start of a TNF-blocker.

DAS28 for RA. 28 joints included. tender and swollen joint count (TEN28, SWO28). Erythrocyte sedimentation rate (ESR) is measured. The patient makes a subjective assessment (SA) of disease activity.
DAS28 ≤ 3.2 Inactive > 3.2 but ≤ 5.1 Moderate > 5.1 Very active
ASDAS for AS. Combines five disease activity variables in one single score
ASDAS

Osteoclasts will be differentiated from untreated patients and patients under several TNF blockers.

Healthy donors age and sex matched to the patients - Healthy donors were not under any therapy therefore they were not at risk and Adverse effects were not assessed.
