Diseases similar to arthritis (RA)
Osteoarthritis
- Normal blood samples
Borrelia arthritis
- Often knee-jointed, non-symmetric, CCP antibody. Borrelia tests knock out
Fibromyalgia
- Widespread pain, no obvious swelling, normal blood tests
Haemochromatosis
- Fewer attacked joints, high hemoglobin (blood percentage) and very high iron level (ferritin)
Lupus (Systemic lupus erythematosus, SLE)
- Not a-CCP, but ANA is clearly elevated, rash
Mixed connective tissue disease (MCTD)
Multicentric Reticulohistiocytosis
- Rare disease
- Nodes under the skin (histiocytes / macrophages)
- Arthritis in PIP and DIP joints
Neuropathy
- Disease of the nervous system, numbness, pain or decreased feeling, most often in the feet. Normal blood samples (check B12 vitamins in blood sample). May occur in other rheumatic diseases, especially Vasculitis
Pachydermodactyly
- Swollen joint fibromatosis, typically middle finger (PIP) in the fingers
Polymyalgia rheumatica
- Higher age
- Quick start
- Rare joint swelling
- Not CCP antibody
Psoriatic arthritis
- Not CCP Antibodies in blood
Sarcoidosis (with swollen joints)
- Typical lung abnormailities, not α-CCP
Septic arthritis
- Infection
- Mycobacterium marinum infection
- Granulomatous skin symptoms, arthritis, fever
Metabolism, low (hypothyroidism)
- Normal blood samples excluding metabolic tests (f-T4 is low, TSH is high)
Gout
- Not CCP Antibodies in blood
- High uric acid
- Uric acid crystals in joint fluid
Virus Infections
- Parvo virus (reference: Moor TL, 2000)
- HIV (Reference: Cunha BM, 2015)
