ABSTRACT
@#INTRODUCTION: Rheumatoid arthritis (RA) is one of systemic chronic progressive inflammatory disorders based on immunological disharmonies. Poorly controlled systemic inflammation in RA often leads to renal diseases such as secondary amyloidosis. CASE PRESENTATION: A 30-year-old man complained of swelling and tenderness of multiple joints gradually worsened the past 7 years. His laboratory examination showed anemia, positive rheumatoid factor (RF) and anti-citrullinated protein antibody (ACPA). C-reactive protein (CRP) was 48.7 mg/L (Normal value is <5 mg/L), increase in serum creatinine and protein was +3 in urine. His estimated glomerular filtration rate (e-GFR) was 58.3 mL/min/1.73 m2 Radiologic examinations of joints revealed features that support the diagnosis of rheumatoid arthritis. Renal biopsy was done revealed amyloid deposit. He was diagnosed with rheumatoid arthritis and secondary renal amyloidosis. CONCLUSION: Early proper diagnosis of RA is important and immunosuppressive drugs might slow disease progression by controlling the inflammatory process We discussed the importance of early diagnosis and the use of better treatment in managing RA to prevent renal amyloidosis.
