- 14. 14 Possible causes of leukopenia in SLE • Immune destruction • Marrow suppression • Hypersplenism • Drugs
- 15. 15 Possible causes of anemia in SLE • Anemia of chronic disease • Auto-immune hemolytic anemia • Hypoplastic anemia • Blood loss due to thrombocytopenia or NSAID use • Hypersplenism • Anemia of renal failure
- 16. 16 AN APPROACH TO THE MANAGEMENT OF LUPUS THROMBOCYTOPENIA • Confirm diagnosis by examining peripheral smear and bone marrow examination, and determine severity • Rule out drug effects and discontinue all but absolutely essential drugs • Rule out thrombotic throbocytopenic purpura (may be indicated by anemia with pronounced reticulocytosis and fragmented erythrocytes in the peripheral smear) • Rule out infection： viral：HIV, HBV, CMV bacterial：subacute bacterial endocarditis, gram-negative sepsis • Look for evidence of lupus activity in other organs; beware of major organ involvement • Use prednisone 0.25-1.0mg/kg/day for 3-4 weeks if platelets < 50.000/mm3 (unless otherwise indicated for other manifestations of lupus); taper after 3-4 weeks The goal is a stable platelet count > 50.000/mm3 • If prednisone fails or unable to tape, consider danazol (400-800mg/day),-globulin or splenectomy • In patients refractory to these modalities or patients with major organ involvement, use monthly pulses of cyclophosphamide for at least 6 months Fig. 7.14 An approach to the management of lupus thrombocytopenia.
- 17. 17 Lupus lymphadeenitis (I) • The prevalence of lymphadenopathy range from 12- 59% of lupus patients • The most common sites are cervical (43%), mesenteric (21%), axillary (18%) and inguinal (17%). Unusual sites such as hilar, mediastinal and retroperitoneal were also reported • The pathognomonic pathologic feature of lupus lymphadenitis, the hematoxylin body, was described by Ginzler and Fox in 1940, which stain with periodic acid- Schiff and Feulgen methods, are coalescent amorphic aggregates of deeply basophilic material found within areas of lymph node necrosis. • The hematoxylin bodies are highly specific for SLE, are also found in glomeruli, endocardium and spleen
- 18. 18 Lupus lymphadeenitis (II) • Other lymph node features include paracortical focl of necrosis marked infiltration by histiocytes, lymphocytes and plasma cells and the preesence of imunoblasts. Neutrophils, eosinophils and granulomata are conspiculously absent. • Both lupus lymphadenitis and KFD are characterized by of histiocytic and immunoblastic infiltrates. A prominent plasma cell component strongly suggests lupus lymphadenitis. When present, hematoxylin bodies are virtually diagnostic of SLE. • The clinical feature, building on these pathologic resemblances, supports a link between KFD and SLE. Perhaps KFD and SLE share a common inclting event, such as exposure to an enviromental or infectious agent, that can produce either disorder. Alternatively, KFD may be an antoimmune-midiated necrotizing lymphadenitis that can remain self-limited or develop into SLE

- 22. 22 Common Clinical and Laboratory Findings in Lupus Nephritis • Disordered fluid and electrolyte balance Nocturia, decreased urinary concentrating capacity, hyperkalemia, renal tubular acidosis • Nephritic syndrome Hematuria, cellular casts; variable bypertension, edema, proteinuria, azotemia • Nephrotic syndrome Frothy urine, edema, proteinuria >3.5g per day, lipiduria (fatty casts, oval fat bodies, doubly refractile fat bodies), hypoalbuminemia, hyperlipidemia • Secondary complications of nephrotic syndrome include volume depletion, prerenal azotemia, venous thrombosis, pulmonary embolism, atherosclerosis, hypogammaglobulinemia • Renal insufficiency Acute, rapidly progressive or chronic renal failure
- 23. 23 Characteristic Clinicopathologic Correlations in the Major Classes of Lupus Nephritis Normal or minimal disease Mesangial lupus nephritis Clinical：low-grade hematuria, proteinuria, normal renal function Pathology：increased mesangial cells, matrix, and immune complexes; patent glomerular capillary loops Focal proliferative lupus nephritis Clinical：nephritic urine sediment, variable but usually nonnephrotic proteinuria Pathology：segmental proliferation, necrosis, crescents compromising capillary loops in <50% of glomeruli; mesangial and subendothelial immune complex deposits Diffuse proliferative lupus nephritis Clinical ：nephritic urine sediment, nephrotic syndrome, hypertension, variable renal insufficiency Pathology：global proliferation, necrosis in >50% of glomeruli; variable sclerosis, atrophy, and fibrosis; mesangial, subendothelial, and subepithelial immune complex deposits Membranous nephropathy Clinical：nephrotic syndrome Pathology：diffuse capillary loop thickening; subepithelial immune deposits

- 25. 25 INDICES OF ACTIVITY AND CHRONICITY IN LUPUS NEPHRITIS* Activity Index (Range 0 to 24) Glomerular hypercillularity Leukocyte exudation Karyorrhexis/fibrinoid necrosis Cellular crescents Hyaline thrombi Tubulointerstitial inflammation Chronicity index (Range 0 to 12) Glomerular lesions Glomerular sclerosis Fibrous crescents Tubulointerstitial lesions Tubular atrophy Interstitial fibrosis *Individual lesions are scored 0 to 3+ (absent, mild, moderate, severe). Indices are composite scores for individual lesions in each category of activity or chronicity. Necrosis/karyorrhexis and cellular crescents are weighted by a factor of 2.
- 26. 26 INDICATIONS FOR RENAL BIOPSY IN LUPUS NEPHRITIS Proteinuria of >1g/day The threshold is conventionally 1-2g/day Less proteinuria does not preclude biopsy if it occurs in the context of major serologic abnormalities, especially hypocomplementemia At the other extreme, the presence of full-bolwn nephrotic and nephritic syndromes may make renal biopsy unnecessary Progressive azotemia Decreasing renal function in associtaion with active urinary sediment is an indication for biopsy in order to assess the extent of crescents and necrosis which would warrant very aggressive therapy Ambiguity or inconsistency of data Lupus nephritis of indeterminate duration, severity and potential responsiveness warrants the establishment of a fresh baseline database including determination of class,activity and chronicity indices Overlapping clinical features Situations where clinical and laboratory data are compatible with different classes of lupus nephritis, for which different approaches to management are warranted Redirection of therapy Partially treated or incompletely responsive lupus nephritis for which a change in therapeutic plan is deemed appropriate
- 27. 27 SLE and ESRD (1) • 5-22% of SLE patients progress to ESRD requiring H/D • In USA, Iupus nephropathy accounting for 1.4% off all ESRD • Decreased clinical and serological lupus activity following ESRD. Some theories had： 1.Depressed cellular and humoral immunity 2.Lack of mediators produced by the kidney 3.Removal of lupus factors by dialysis itself 4.Nature end point in SLE • Survival of lupus patients on dialysis versus non-SLE dialysis patients：no significant
- 28. 28 SLE and ESRD (2) • Renal transplant graft survival of lupus versus non-lupus patients：no difference • Lupus patients have slightly better outcome with LR rather than CAD grafts • The transplantation time following dialysis need at least 3 months • Recurrence of transplanted allograft is often similar to histologic or immunofluorescent type as in the origin kidney, but it is a rare event.

- 33. 33 Pathologic studies in NPLE Several autopsy series agree on several important points There is no pathognomonic lesion that NPLE causes in the brain that is diagnostically specific like the wire loop lesion observed in lupus nephritis. Active vasculitis is rare, bland vasculopathy (vascular hyalinization, perivascular imflammation, and endothelial proliferation associated with microinfarcts and hemorrhage is the most common pathologic abnormalities seen.) Clinical manifestations may not be readily explained by pathologic findings, some NPLE patients, particularly those with diffuse neuropsychiatric manifestations may have normal or unremarkable brain pathology.
- 34. 34 Proactive and preventive strategies in addition to lupus therapies(1) • Patients education programs, eliminate patient nonadherence • Monitor vital signs, update physical examination, and have laboratory work done • Adhere to a general conditioning exercise program to minimize osteoporosis and muscle atrophy • Cognitive therapy for lupus “fog”;biofeedback for Raynaud’s phenomenon • Counseling and stress management • Physical and occupational therapy, ergonomic work station evaluation
- 35. 35 Proactive and preventive strategies in addition to lupus therapies(2) • Aggressive proactive management of blood pressure, blood sugars, serum lipids, and weight. Smoking cessation. • Yearly bone densitometry and osteoporosis prevention measures. • Annual electrocardiogram and chest x-ray • Prompt evaluation of all fevers • Periodic screening with carotid duplex scanning, treadmill, or stress testing; screening for, and prophylactic management of, antiphospholipid antibodies.
- 36. 36 Therapies for lupus patients with skin lesions(1) • General – Avoid sun: clothing, sunscreens, avoid hot part of day with most UV-B light, camouflage cosmetics – Stop smoking (so antimalarials works better) – Thiazides and sulfonylureals may exacerbate skin disease

- 38. 38 Therapies for lupus patients with skin lesions(3) • Advanced therapy for resistant causes – Subacute cutaneous lupus: mycophenylate mofetil, retinoids, or cyclosporine – Discoid lesions: chloroquine, clofazimine, thalidomide, or cyclosporine – Lupus profundus: dapsone – Chronic lesions over 50% of body: topical nitrogen mustard, BCNU, or tacrolimus – Vasculitis: may need immunosuppressives
- 39. 39 Therapy for lupus patients with arthritis (no internal organ involvement) • First line: NSAIDs • Cyclooxygenase-2 specific inhibitors (but may induce thrombotic risk in patients with antiphospholipid antibodies) • Low dose hydroxychloroquine(200mg twice a day)

- 43. 43 Life-Threatening Manifestations of SLE: Responses to glucocorticoids(3) • Manifestations not often responsive to glucocorticoids – Thrombosis—includes strokes – Glomerulonephritis—scarred end-stage renal disease, pure membranous glomerulonephritis – Resistant thrombocytopenia or hemolytic anemia—occurs in a minority of patients; consider splenectomy, cytotoxics, danazol, or cyclosporine/neoral therapies – Psychosis related to conditions other than SLE, such as glucocorticoid therapy
- 44. 44 Therapy for patients with lupus nephritis • Previously untreated patients with active lupus nephritis or severe manifestations ( decreased renal function and /or high- grade proteinuria) – First line: high doses of corticosteroids (about 1mg/kg/day) – Cytotoxic drugs or other immunosuppressive drugs
- 45. 45 The indications of cytotoxic drugs use in the treatment of lupus nephritis • Active and severe GN despite treatment with high dose prednisone • Responded to corticosteroids but require an unacceptably high dose to maintain a response. • Unacceptable side effects from corticosteroids. • Chronic damage on a renal biopsy and other indicators of a poor prognosis.
- 46. 46 Systemic therapies for nonorgan- threatening lupus • Nonsteroidal anti-inflammatory drugs • Antimalarials • Thalidomide • Hormonal interventions: dehydroepiandrosterone, testosterone patches, bromocriptine, prolactin • Immunosuppressive therapies: azathioprine, methotrexate, leflunomide

- 48. 48 Use of Cytotoxic Drugs in SLE : Azathioprine • requires 6–12 months to work well • 1–3 mg/kg/day(initial dose) • 1–2 mg/kg/day(maintenance dose) • Advantage:probably reduces flares, reduces renal scarring, reduces glucocorticoid dose requirement • Side effects: Bone marrow suppression, leukopenia, infection(herpes zoster), infertility, malignancy, early menopause, hepatic damage, nausea
- 49. 49 Use of Cytotoxic Drugs in SLE: Cyclophosphamide • requires 2–16 weeks to work well • Initial dose:1-3 mg/kg/day orally or 8–20 mg/kg intravenously once a month plus mesna • Maintenance dose:0.5–2 mg/kg/day orally or 8– 20mg/kg intravenously every 4–12 wks plus mesna • Adverse effects:probably reduces flares, reduces renal scarring, reduces glucocorticoid dose requirement • Adverse effects: marrow suppression, leukopenia, infection, infertility, malignancy, menopause,cystitis,nausea
- 50. 50 The treatment in lupus patients with autoimmune thrombocytopenia • Splenectomy • Danazol • Immunosuppressive or cytotoxic drugs: azathioprine, cyclophosphamide • Intravenous immunoglobulin(IVIG)
- 51. 51 Other management principles in the treatment of lupus patients(1) • Thrombosis -Anticoagulation • Recurrent fetal loss with antiphospholipid -Heparin in low dose or low-molecular-weight heparin with or without aspirin -If heparin ineffective or not tolerated, use low-dose aspirin alone -Glucocorticoids plus aspirin in moderate to high dose may be used but is controversial • Thrombocytopenia or hemolytic anemia -Intravenous gamma globulin, splenectomy, danazol, cyclosporine, cytotoxic drugs
- 52. 52 Other management principles in the treatment of lupus patients(2) • Seizures without other serious manifestations -Anticonvulsants • Behavior disorders or psychosis without other serious manifestations: -Psychoactive drugs, neuroleptics • Pure membranous glomerulonephritis: -Limited trials of immunosuppressives or no specific treatment
