[Early reumatoid arthritis]

Area of Science:

• Immunology
• Rheumatology
• Genetics

Background:

• Rheumatoid arthritis (RA) is a systemic autoimmune disease causing joint destruction.
• RA pathogenesis involves genetic (e.g., HLA-DRB1) and environmental factors (e.g., Porphyromonas gingivalis).
• Inflammation and autoantibodies precede clinical RA symptoms.

Purpose of the Study:

• To explore novel biomarkers for early RA detection.
• To investigate the role of anti-carbamylated protein antibodies (anti-CarP), adipocytokines, and vitamin D in RA.
• To emphasize the importance of early intervention with disease-modifying anti-rheumatic drugs (DMARDs).

Main Methods:

• Review of genetic and environmental risk factors in RA.
• Analysis of established serological markers like rheumatoid factor (RF) and anti-citrullinated peptide/proteins antibodies (ACPA).
• Evaluation of emerging biomarkers and therapeutic strategies.

Main Results:

• Established genetic and environmental factors contributing to RA.
• Identification of RF and ACPA as key serological markers.
• Emerging biomarkers like anti-CarP, adipocytokines, and vitamin D are under investigation.
• Early DMARD therapy, within the "window of opportunity", shows significant long-term benefits.

Conclusions:

• Early diagnosis and intervention are critical for managing RA.
• Novel biomarkers are needed for pre-destructive phase detection.
• Timely DMARD treatment can achieve long-term or complete remission in RA patients.
