Lupus erythematosus

Definition Lupus erythematosus LE is classified as connective tissue disease. It occurs predominantly in females in the reproductive years. Multiple abnormal immune responses are present. It may involved any organ of the body and is manifested in many forms. It may be life-threatening when it becomes severe.

Etiology suggestion : the findings of 100 LE family surveys : genetic factors the findings of 100 LE family surveys : Family history positive : 12 % The prevalence of SLE in first-degree relatives is 1.84 % The degree of heritability was 56 % In addition, the concordance rate in monozygotic twins comes to over 50% suggestion : LE is multifactorial inheritance Environmental influence high

Etiology Enviornmental influence Virus infection-- other bacterial infections are seldom Physical factor -- sunlight ,coolness, wetness, ray Emotional factor ---stress, worry Endocrine factor –high estrogen ,prolactin drugs -- more than 20 drugs such as penicillin, phenytoin may induce symptomatic LE

Pathogenesis Environmental influence (infection, sunlight, drug) Genetic factor Immuno-modulatory function disorder Auto-antigen formed Sensitivitied T- lymphocytes Various auto antibody Immune-complexes precipitation Blood cell injured Organs injured Alterations in organs

Clinical manifestation Discoid LE ←→★ Systemic LE

Discoid lupus erythematosus, DLE Skin lesions are predominantly manifested Eruptions may occur singly or be multiple localized DLE Lesions localized on face, dorsa of the hand generalized DLE Lesions widespread on trunk ,extremities

Skin lesions in discoid LE Red macules or papules associated with edema→→ discoid eyrthematosus with adherent scales, horny plugs—-centrally atrophy, dyspigmentation, telangiectasia

录象片断

skin lesions in discoid LE Favorite sites are malar areas, bridge of nose, lower lip, ear, scalp and dorsa of the hand

录象片断

Skin lesions in discoid LE atrophy in the scalp → false alopecia areata lesions on low lip may be eroded

Systemic lupus erythematosus SLE may involved any organ of the body and is manifested in many forms. It will be life-threatening when severely. Basic pathology alteration shows necrotizing vasculitis

Skin and mucous membrane lesions Skin involvement occurs in 80% of cases. It is often the earliest abnormality and predominant symptom. Sunlight may develop the facial eruption and a severe relapse. Mulity form : erythema, papule, blood blister Specific eruption: malar erythema erythema on finger pulp or toe pulp erythema around the nail fold

Skin and mucous membrane lesions Malar erythema --red macules associated with edema, begin on the malar areas and bridge of the nose, then spread on the ear, tip of the nose, upper eyelids

录象片断

Finger pulp or toe pulp show prunosus macule associated with edema, telangiectases or hemorrhagic, atrophy,necrosis. they may also occur on palms, soles

Skin and mucous membrane lesions Eruptions widespread the body may be vesicle, petechia, nodule and livedo reticularis, erythema multiform-liked eruptions

Skin and mucous membrane lesions Oral mucosal erythema--erosions, shallow ulcerations occur commonly on lip, buccal mucosa, the tongue, palatine mucosa,, gums of the teeth .

Other internal organs involvement Renal –nephritic or nephrotic—chronic renal insufficiency with azotemia Heart —myocarditis, pericarditis and endocarditis Pulmo —pleural effusions, interstitial lung disease locomotor system -Myositis, arthritis Digestive system —gastroenteritis, peritonitis hepatitis Nervous system —mental disorder, central and peripheral neuritis or vascular lesions Eye--Retina neural degeneration, conjunctivitis, subhyaloid hemorrhage Others—Raynaud’s phenomenon, fatigue and fever, lymphadenectasis

Laboratory findings Hypocytosis Proteinuria (erythrocyturia \leukocyturia\ cylindruria) Elevated sedimentation rate Positive rheumatoid factor Elevated immunoglobulin Low level of serum complement

laboratory findings injured nuclear Anti-nucleoprotein antibody homogeneous body Be phagocytized by PMN Attract PMN groups of cell LE cell

laboratory findings Special test(1)LE cell( cell smear)

laboratory findings Special test (2)ANA (indirect immuno-fluorescence ) (3)anti ds-DNA antibody (4)ENA(-Sm、RNP、Ro、La antibodies) (immuno-blot) (5)LBT lupus band test (direct immuno-fluorescence )

histology There is hyperkeratosis in epidermis follicular orifice dilat, keratinous plug in it spinous layer atrophy liquifaction degeneration of basal cells lymphocytes and plasma cell infiltrate in dermis specially around the appendages of the skin and vascellum

Diagnose DLE depended on typical eruptions Discoid erythematosus Adherent scales Horny plugs Centrally atrophy Dyspigmentation Telangiectasia

1982 Revised American Rheumatism Association Criteria for the diagnosis of SLE(1) 1)Malar erythema 2)discoid LE 3)Photosesitivity 4)Oral ulcer 5)Nonerosive arthritis 6)Serositis (pericarditis or pleurisy) 7)Nephropathy (albuminuria or cellular casts) 8)CNS disorder (unexplained seizures or psychosis)

1982 Revised American Rheumatism Association Criteria for the diagnosis of SLE (2) 9)Hematologic disorder (hemolytic anemia with reticulosis, or leucopenia below 4000 on two occasions, or lymphopenia below 1500 on tow occasions) 10)Immunologic disorder: positive LE-cell preparation, or antibody to native DNA or SM antigen, or false positive STS 11)Antinuclear antibody in abnormal titer, unexplained A patient may be said to have SLE if four or more criteria are satisfied.

Treatment Avoid exposure to strong sunlight, to excessive cold, heat, tension , tiredness and infection For predominant skin lesion, hydroxychloroquine, thalidomide, tripterygium wilfordii are recommended , topical application of carticosteroid For patients whose organs involved, carticosteroid should be administered, and combinations of steroid with immunosuppressive drugs are recommended when necessary Others : nonsteroidal anti-inflammatory agents, immuno-modulatory drugs and other supportive treatments
