Diagnosis / Suspected SLE is based on
- Disease history (check SLICC criteria below)
- Medical investigation and findings
- Laboratory tests
- Tissues from kidneys (kidney biopsy) if kidney involvement
- SLE begins most commonly in women of childbearing age, more often among people from Asia and Africa
- Differential diagnoses, please see here

- Weight loss last 3-6 months
- Immunosuppressive treatment until now
- Prednisone
- Plaquenil
- Azathioprine
- Methotrexate
- Mycophenolate (CellCept)

Clinical examination at SLE
- Blood pressure and pulse
- Heart and lungs (auscultation)
- Skin and hair
- Joint
- Edema (kidney)
- Neurological
Blood and urine samples
- The sedimentation rate (ESR) is often high
- CRP almost normal, but increases with infection, arthritis and pulmonary (pleurisy) or heart bag inflammation (pericarditis)
- Cell counts (Hemoglobin, lymphocytic leukocytes, platelets)
- Complement factors C3 and C4
- Urine with signs of glomerulonephritis (proteins, blood, protein / creatinine, cylinders)
- Blood tests that take initially, then rarely
- Antibody samples (in blood) ANA, ENA, DNA antibody, anti C1q
- Antifosfolipid antibodies (Lupus anticoagulant via hematological / coagulation laboratory), α-cardiolipin and beta-2 glycoprotein (β-2GP).
X-ray examination of lungs
- Exclude signs of manifestations in the pleura / pericard
- «Shrinking lung» with diaphragm height
What we should also ask the patient about
- How strong is your pain today (scale 0-100)?
- How strong is the fatigue today (scale 0-100)?
- How do you perceive your disease activity today (scale 0–100)?
- (The doctor can also add his assessment of the disease activity, scale 0-100)
Follow-up
- All patients with aktiv SLE should be followed up by both a specialist and a GP
- The frequency of controls will depend on the disease activity, complications and medications used
- If new symptoms, check keywords for medical history (see above)
- Clinical examinations as mentioned above
- Blood and urine are checked
- Antibody and complement factors need not be checked every time
- By pregnancy close monitoring of rheumatologists and obstetricians should be organized as soon as possible
- Validated targets for disease activity can be done at SLEDAI
Referral to specialist
- Define what the diagnosis / suspicion of SLE is based on (see above)
Patients should preferably be referred to local rheumatological department. Patients living in the Health Region South-East can also be referred Rheumatology Department, Rikshospitalet, Oslo
Postbox 4950 Nydalen, 0424 OSLO. The department can receive patients also from the country by the way when the capacity allows.
