Brief Summary
Dipyridamole, a medication extensively used in combination with aspirin for stroke prevention, is a promising new treatment for lupus. Dipyridamole has been shown to inhibit certain lymphocyte populations that are over-reactive in lupus and to delay the emergence of lupus-related pathology in mice with lupus. The investigators are interested in investigating the efficacy of dipyridamole in preventing flares in patients with lupus and its impact on biomarkers of disease activity.

Outcome Measures
Primary Outcomes (1)
British Isles Lupus Assessment Group Index-based Combined Lupus Assessment (BICLA)
This is a landmark measure of percentage of patients who meet response criteria. To meet the BICLA response measure a patient must, compared to baseline, have a decrease in all moderate or severe scores on the British Isles Lupus Assessment Group (BILAG) index by at least one severity grade (Severe disease (BILAG A score) must drop to at least moderate (B or better) and B must drop to at least mild (C or not present). Also, there must be no increase in any other BILAG organ scores, no increase in The Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score, and no increase in the physician's global assessment (PGA) by more than 10% of the scale. Furthermore, there may no off protocol medication increases. Note on all scales mentioned a higher score signifies greater disease activity. Ranges on BILAG could be 0-108 but are rarely greater than 36. SLEDAI could range 0-105 but is rarely greater than 20. PGA 0-100 but rarely greater than 76.

Eligibility Criteria
You may qualify if:
- Patients with SLE meeting the 1997 ACR Classification Criteria
- Evidence of positive ANA or anti-dsDNA within one year of screening
- SLEDAI ≥4 or ≥1 BILAG A or B at screening, despite standard of care
You may not qualify if:
- Leukopenia (WBC \<2.000/mm3) or lymphopenia (lymphocytes \< 300/mm3)
- AST or ALT \>3 times above normal cut off values
- Acute lupus nephritis defined as class II, IV or V nephritis diagnosed within 6 months or prot/creat \> 1.5 gm/gm due to active lupus or in process of receiving induction therapy for nephritis
- Active CNS lupus affecting mental status
- Pregnancy or breast feeding
- Current requirement for anticoagulation
- Contraindication to aspirin or dipyridamole, including history of recent or severe GI bleeding, hemoglobin \<9 mg/dL, platelet count of \<30,000 /mm3 or unstable platelet count
- Any other medical condition, whether or not related to lupus which, in the opinion of the investigator would render the patient inappropriate or too unstable to complete the study protocol
- Inability or unwillingness to understand and/or sign informed consent
