Research Article: MTHFR and MTRR Genetic Polymorphism of Methotrexate Therapy Outcomes in Early Rheumatoid Arthritis
Introduction:
Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease, mainly characterised by symmetrical pain and swelling of small joints in the hands and the feet. When chronic inflammation is not properly controlled over a long period of time, it can eventually lead to irreversible damage to the joint structures. Methotrexate (MTX) is a folic acid inhibitor with structural and physicochemical properties similar to folic acid, which acts as an anti-inflammatory and anti-proliferative agent in the body. MTX is…
