Assessment of Galectin-9 in Rheumatoid Arthritis and Its Correlation With Disease Activity

Rheumatoid arthritis (RA) is an autoimmune disease in which a symmetrical Synovial inflammation, bone destruction occur in both small and big Joints. If left untreated, this illness does not generally cause death, but it does drastically affect the quality of life and life expectancy of patients. Although there is no cure for RA, patients are generally on long-term long-acting disease-modifying anti-rheumatic medications (DMARDs) to control joint inflammation, reduce joint damage, maintain joint function, and keep the illness in remission. RA disease activity could be detected be DAS28 score. The DAS28 is a four-item scale that gives an absolute number reflecting disease activity. It includes the number of swollen and tender joints (SJC, TJC), the visual analogue scale of patients' assessment of their general health (VAS-GH), and the erythrocyte sedimentation rate (ESR) in the first hour. In the pathophysiology of RA, cytokine networks play a crucial role. Rheumatoid inflammation has been linked to the generation of proinflammatory cytokines throughout time. Increased cytokine levels, such as tumour necrosis factor (TNF) and interleukin-6 (IL-6), represent rheumatoid synovial inflammation and have been linked to RA disease activity and anti-cytokine therapeutic response. The relationship between circulating cytokine levels and the phenotype of RA illness is, however, poorly understood. Anti-citrullinated peptide antibodies (ACPA) are effective in the diagnosis of RA and have been linked to joint destruction progression and therapy response in RA patients. However, the relationship between ACPA status and proinflammatory cytokines during the course of RA illness is yet unknown. Galectins are lectins with carbohydrate recognition domains (CRDs) that are extremely similar in sequence and exclusively bind to β--galactoside carbs. There are at least 15 galectins found in mammals, each having one or two CRDs comprising roughly 130 amino acids. Galectins have a wide ra
