Rheumatoid arthritis (RA) is a chronic debilitating autoimmune
disease, that causes joint damage, deformities, and decreased functionality.
In addition, RA can also impact organs like the skin, lungs, eyes,
and blood vessels. This autoimmune condition arises when the immune
system erroneously targets the joint synovial membrane, resulting
in synovitis, pannus formation, and cartilage damage. RA treatment
is often holistic, integrating medication, physical therapy, and lifestyle
modifications. Its main objective is to achieve remission or low disease
activity by utilizing a “treat-to-target” approach that
optimizes drug usage and dose adjustments based on clinical response
and disease activity markers. The primary RA treatment uses disease-modifying
antirheumatic drugs (DMARDs) that help to interrupt the inflammatory
process. When there is an inadequate response, a combination of biologicals
and DMARDs is recommended. Biological therapies target inflammatory
pathways and have shown promising results in managing RA symptoms.
Close monitoring for adverse effects and disease progression is critical
to ensure optimal treatment outcomes. A deeper understanding of the
pathways and mechanisms will allow new treatment strategies that minimize
adverse effects and maintain quality of life. This review discusses
the potential targets that can be used for designing and implementing
precision medicine in RA treatment, spotlighting the latest breakthroughs
in biologics, JAK inhibitors, IL-6 receptor antagonists, TNF blockers,
and disease-modifying noncoding RNAs.
