visceral involvement or refractory SLE as defined by either:
- kidney involvement: with the criteria for lupus renal BILAG A and a creatinine
clearance > 30 ml/min/m2, not explained by other causes than SLE activity with a
renal biopsy of less than 12 months showing a class III or IV lupus nephritis
- Any other type of vital organ involvement except mesenteric vasculitis with BILAG
neurologic category A, cardiovascular or pulmonary category A, vasculitis
category A
- Auto-immune cytopenias (hemolytic anemia and/or thrombo-cytopenia) defined as
BILAG hematologic category A and confirmed by a bone marrow aspirate

anticoagulation after at least 6 months of the best standard local therapy using
CY or MMF either alone or successively according to:
- the short term Eurolupus protocol low dose CY regimen of 6 x 500 mg iv CY at
2 weeks interval or
- the conventional treatment with 0.75 g/m2/month x 6 iv cyclophosphamide or
- MMF at 2 g daily for 3 to 6 months plus oral steroids above 0.5 mg/kg/day

5. Written informed consent.
Exclusion Criteria:
1. Pregnancy, breast feeding or unwillingness to use adequate contraception methods
during study (see 7.5).
2. Severe concomitant disease:

DLCO < 40% predicted, respiratory failure as defined by a resting arterial oxygen
tension (PaO2) < 70 mmHg) and/or resting arterial carbon dioxide tension (PaCO2)>
50 mmHg) without oxygen supply

or multigated radionuclide angiography (MUGA)); > 1 cm pericardial effusion on
cardiac echography; uncontrolled ventricular arrhythmia.
3. Liver failure defined as a transaminases levels (ASAT, ALAT > 2 normal) unless related
to activity of the disease.
4. Severe psychiatric disorders, including severe psychosis related to SLE disease that
may prevent the ability to sign informed consent or undergo the procedure.
5. Concurrent neoplasms or myelodysplasia except for localized basal cell carcinoma or
squamous skin cancer or in situ cervical carcinoma of the uterus.

30 x 109/l, anaemia < 8 g/dl, CD4+ T lymphopenia < 200 x 106/l.
7. Uncontrolled acute or chronic infection, including HIV, HTLV-1, 2 positivity,
Hepatitis B surface Ag positive, hepatitis C PCR positive.
