Criteria of rheumatoid arthritis
1- Morning stiffness lasting > 1 hour.
2- Arthritis of 3 or more joints areas .
3- Arthritis of hand joints and wrists (at least in one area e.g wrist, Mep or PIP joint).
4- Symmetric arthritis i.e. simultaneous invoivement of the same joint areas on both sides .
5- Rheumatoid nodules.
6- Positive rheumatoid factor.
7- Typical radiological changes (Hand and wrist)
• Erosions, Loss of joint space,
• Juxta-articular osteoporosis.
• The above criteria must be present for at least 6 weeks.
• Our diagnosis is made with 4 or more criteria .
• Seronegative arthropathies.
• Gout, pseudogout and osteoarthritis.
• Viral arthritis.
2- Interstitial pulmonary fibrosis ---> cor pulmonale.
3- Myocarditis ---> biventricular failure.
2- SLE ~ GN ( nephrotic OR nephritic ).
3- Any arthropathy ---> NSAID ---> minimal lesion GN.
4- FMF
• Arthritis • Serositis • Amyloidosis kidney ( late ) .

Differential Diagnosis of rheumataid disease
• Connective tissue diseases.• Seronegative arthropathies.

Differential Diagnosis of rheumatoid arthritis from rheumatic fever
Q : Patient with rheumatoid arthritis then he developed lower limb oedema what is DD ?
1- Nephrotic syndrome ( due to drugs or amyloidosis)2- Interstitial pulmonary fibrosis ---> cor pulmonale.
3- Myocarditis ---> biventricular failure.
Q : Patient C/O at arthropathy then developed proteinuria , what is DD ?
1- Rheumatoid arthritis ~ nephrotic (drugs OR amyloidosis).2- SLE ~ GN ( nephrotic OR nephritic ).
3- Any arthropathy ---> NSAID ---> minimal lesion GN.
4- FMF
• Arthritis • Serositis • Amyloidosis kidney ( late ) .
