Rheumatoid Arthritis (RA) is a common chronic inflammatory and destructive arthropathy that cannot be cured.Interlukin-1 (IL-1), IL-6 and tumor necrosis factor (TNF- α) are the key cytokines that drive inflammation in the disease.
The study was established to shed light on the possible role of IL-1 and TNF- α in pathogenesis of RA.
PATIENTS AND METHODS:
Rheumatoid Factors (RF),TNF-α and IL-1 were detected by Enzyme-Linked Immunosorbent Assay (ELISA) .C-reactive protein(CRP) on the other hand has been detected by using latex agglutination kit in the serum of 50 Iraqi patients with RA in comparison with 50 healthy individuals.
Significant high levels of IL-1and TNF- α were observed in RA patients sera with P-value ( 0.04 and 0.001) respectively compared to healthy control group, in addition a positive linear association was found between the concentration of IL-1and TNF- α and CRP with P-value ( 0.05 and 0.001) respectively.
IL-1and TNF- α play a role in pathogenesis of RA
