  1. Treatment of SLEH. Michael BelmontHospital for Joint DiseasesNYU School of Medicine

  2. SLE SUBSETS • Discoid lupus erythematosus (DLE) • Systemic lupus erythematosus (SLE) • Drug-induced SLE (DANA vs DILE) • ANA negative lupus/Ro lupus/SCLE • Antiphospholipid antibody syndrome • Neonatal lupus

  3. SLE:Demographics • Affects .5 million (.2%) vs 1.5 million (.6%) of US population (epidemiologic vs LFA random digit dialing telephone survey) • Female:Male ratio of 10:1 • 70% of SLE: females between ages 15-45 • African American to Caucasian ratio 3:1 • Highest prevalence in Afro-Caribbean females 1:250 • Genetic factors HLA-A1, B8, Dr3 - C4A null genes - Fc receptor polymorphisms -gene linked to chromosome 1

  4. SLE:Demographics • Environmental factors - Concordance for monozygotic twins is 30% (70% of genetically identical twins will not share the disease) • Child of SLE mother risk of SLE 1:15 (7%) • ANA positive in 5-20% of population. 10 times more likely to have false positive ANA than disease

  5. SLE:ETIOLOGY • AUTOANTIBODY PRODUCTION • GENERATION OF CIRCULATING IMMUNE COMPLEXES • EPISODIC COMPLEMENT ACTIVATION

  6. SLE:Pathobiology • Autoantibodies (AIHA, AITP, Anti-neuronal antibody, APS) • Immune complex disease (microangiitis and vasculitis) • Neutrophil and endothelial cell adhesive interaction with leukoaggregation • Thrombophilia (Antibody mediated thrombosis in secondary antiphospholipid antibody syndrome with micro and macrovascular noninflammatory occlusion

  7. SEROLOGY • ANA (Titer and pattern: diffuse, speckled, rim, nucleolar, centromere) • double stranded-DNA • Sm • RNP • Ro (SS-A)/La (SS-B) • C3 • C4

  8. POSITIVE ANA • SLE • Non SLE CTD (RA, SS, PSS, CREST, DM/PM) • DRUG-INDUCED • NORMALS (FALSE POSTIVE) • LYMPHOPROLIFERATIVE DISORDER • CHRONIC INFECTION (HIV, Leprosy)

  9. PITFALLS • ANA POSITIVE FIBROMYALGIA • STEROIDS FOR MUSCULOSKELETAL SYMPTOMS • EXCESSIVE DURATION OF STEROIDS • INADEQUATE MONITORING (C3, C4, dsDNA) • DIAGNOSTIC OR THERAPEUTIC DELAYS (RENAL BIOPSY, CYTOTOXICS)

  10. SLE:Health Status • Disease activity (SLEDAI, SLAM. BILAG) • Damage Index (SLICC DI) (disease, treatment or co-morbidity) • Treatment/iatrogenic induced illness (e.g. avascular necrosis of bone, accelerated atherosclerosis, cataracts, striae, immunosupression, etc.) • Infection

  11. TREATMENT • SUNSCREEN • TOPICAL STERIODS • NSAIDs • ANTIMALARIALS • STEROIDS • CYTOTOXICS • CALCIUM, VITAMIN D, FOLATE SUPPLEMENTATION • INFLUENZA VACCINE (annual) • PNEUMOCCOCAL VACCINE (decade)

  12. CLINICAL FEATURES • CONSITUTIONAL • CUTANEOUS • JOINTS • SEROSAL • CYTOPENIAS • RENAL • NEUROLOGIC • ANTIPHOSPHOLIPID ANTIBODY SYNDROME

  13. STEROID THERAPY • ACUTE LUPUS CRISIS • ACTIVE NEPHRITIS • ACUTE ACTIVE CNS • ACUTE CYTOPENIAS (AIHA,AITP) • REFRACTORY SEROSITIS • VASCULITIS • SEVERE CONSTITUTIONAL (fever, fatigue, wgt loss, synovitis, anemia)

  14. CYTOTOXIC THERAPY • Azathioprine, Methotrexate, Leflunomide • Steroid sparing (constitutional, serositis, immune cytopenias) • Articular • Mycophenolate mofetil, Cyclophosphamide • Nephritis, CNS, immune cytopenias, vasculitis

  15. ANTIPHOSPHOLIPID ANTIBODY SYNDROME (APS) • ASYMPTOMATIC • No Treatment • Antiplatelet (ASA 81 mg, Ticlid, Plavix) • THROMBOTIC EVENT (DVT, PE, CVA) • Coumadin INR > 3 • PREGNANCY • ASA 81 mg, Prednisone 40-20 mg, sc Heparin, sc LMWH (IVIG) • CAPS (Catastrophic APS) • Heparin, steroids, pheresis, IVIG, cytoxan

  16. NOVEL THERAPY • Immunoablative chemotherapy with or without autologous stem cell transplant • B-cell toleragen (Single signal anergy) • Complement inhibitors (anti-C5, soluble CR1) • Adhesion molecule inhibitors (anti-ICAM 1 antiCD11b/CD18) • Co-stimulatory pathway inhibitors (anti-CTLA-4, anti-CD40ligand)
