Official title
Effect of cDMARD and Baricitinib Therapy on IL-6, IL-12, IL-15 and IL-23 Expression Levels in Rheumatoid Arthritis Patients
Overview
Rheumatoid Arthritis (RA) is a systemic autoimmune disease characterized by chronic inflammation and articular damage. Continuous medical research has dramatically improved the outcomes for patients with RA. Traditional therapeutic approaches have relied on glucocorticoids, nonsteroidal anti-inflammatory drugs (NSAIDs) and disease modifying antirheumatic drugs (DMARDs) such as methotrexate, sulfasalazine or leflunomide. Glucocorticoids and NSAIDs interfere with the inflammatory cascades while DMARDs impede both the inflammatory and the destructive processes of RA. These drugs, although efficient, are not specifically directed against inflammatory cells or cytokines and are associated with significant toxicity. The development of biologic DMARDs (bDMARDs), has been an important step forward. Their ability to neutralize specific cytokines or target distinct immune cells filled a gap in existing treatment options for RA. \[3\]. However, some patients still have only partial or no response to bDMARDs. More recently, a group of drugs has been developed that inhibit the janus kinase (JAK) family of intracellular tyrosine kinases, which transmit cytokine- mediated signals via the JAK-signal transducer and activator of transcription (STAT) pathway \[4\]. Baricitinib, with a selectivity to inhibit JAK1 and 2, has been FDA approved for RA in 2018 \[5\]. Many cytokines such IL-6, IL-12, IL-15, IL-23, (GM-CSF) and (IFNs) are associated with the pathogenesis of RA. These cytokines transduce signals via the JAK-STAT pathway.
Interventions
- Other blood sample
Total RNA will be extracted from the whole blood using a commercial extraction kit (RNA Extraction Kit, applied biotechnology Co.Ltd, Egypt) according to the manufacturer's instructions. RNA will be stored at -80°C.The extracted RNA will be used for cDNA synthesis using commercial kits (cDNA Synthesis Kit, applied biotechnology Co.Ltd, Egypt), according to the manufacturer's instruction.
Primary outcome measures
- assess the effect of cDMARD and Baricitinib (JAKi) therapy on gene expressions of IL-6, IL-12, IL-15 and, IL-23 in patients with RA relative to the healthy controls. [Time frame: 6 months]
