Discoid lupus
● Affects only the skin and is not lethal - Caused by UV rays
● Macular Rash & Discoid Rash
● Skin biopsy to dx
Systemic Lupus Erythematosus (313-317) ***TEMPERATURE***
● Chronic, progressive, inflammatory connective tissue disorder that affects multiple body systems &organs
o REMISSIONS/EXACCERBATIONS (can end up in the ICU) - Autoimmune
o Attracted to KIDNEY’s—Lupus Nephritis is leading cause of death; this is direct damage to the kidneys
● Poor survival associated with high creatinine, low hematocrit, proteinuria
o Young Women of child bearing age 20-40 Y (primary AA women)
o SLE & DLE both share a disfiguring and embarrassing rash!!
● Clinical manifestations
o Malar rash – red flat or raised rash over cheeks sparing nasolabial folds “butterfly rash”
o Discoid rash – Red raised patches with scaling follicle plugging
o Photosensitivity– discoid skin rash from sun exposure - pt should wear sunscreen or protective clothing
o Oral ulcers–usually painless
o Polyarthritis-multiple joints affected
● Small joints and knees inflamed
● Osteonecrosis from chronic steroid use (5y+)
o Pleuritis with pleural effusion or pericarditis
o Fever is the major sign of exacerbation
o Generalized weakness, fatigue, anorexia, weight loss
o Renal disorders–proteinuria, cellular casts
, Discoid lupusDiscoid lupus
o Neurologic disorders – seizures, psychosis and also peripheral neuropathies
o Raynaud’s phenomena
● Exposure to cold or extreme stress – red, white, blue & pain of digits
o Alopecia or hair loss common
● Diagnostic Tests
o ANA most sensitive but antinuclear antibodies not specific to SLE
o C reactive protein can help differentiate SLE flare from an infection (remains normal if SLE flare)
, Discoid lupusDiscoid lupus 3
o CBC shows pancytopenia (a decrease in all cell types)
● Medical Management
o Topical steroids for skin lesions
o Acetaminophen or NSAIDS (caution with kidneys) – tx joint & muscle pain & inflammation
o Hydroxychloroquine (anti-malarial agent) – dec absorption of ultraviolet light by skin, dec skin lesions
▪ Frequent eye exams – b4 starting and q 6 mon
o Glucocorticoids – Chronic steroid therapy
▪ Take in the am b4 breakfast
▪ Take Ca to prevent osteoporosis
▪ Maintain skin integrity
o Immunosuppressants – methotrexate, azathioprine
o Belimumab – do not receive live vaccines for 30 days b4 tx
● Teaching
● Protect the skin
o Limit sun/ultraviolet light exposure to prevent exacerbation (fluorescent light too)
▪ Long sleeves, lg-brimmed hat, SPF 30+
o Clean skin with mild soap, pat dry and apply lotion
o Cosmetics ok w/ moisturizers and sun protection, no excess powder or drying substances
● Monitor temperature – first sign of exacerbation
● Avoid large crowds and people who are ill, bc immunosuppressed
● Avoid harsh hair tx (permanents or highlights)
● Pregnancy can cause exacerbation
Systemic Sclerosis (Scleroderma) ***SWALOWING PROBLEM***
● Uncommon, chronic, inflammatory, autoimmune connective tissue disease.
● Similar to SLE, but w/a higher mortality rate
● Doesn’t respond to steroids or immunosuppressants, why mortality higher than SLE
● Inflamed tissue becomes fibrotic and then sclerotic (hard) – renal involvement leading cause of death
● Women 25-55, most in 40s
● Diffuse cutaneous *Major organ problems
o First sx – hand and forearm edema w/ or w/o bilateral carpal tunnel syndrome
o Skin thickening on trunk, face, and proximal and distal extremities (most of the body)
o Painless symmetric pitting edema of hands & fingers (sausage like fingers)
o Changes of pigmentation with loss of skin folds & face can become mask like
o Develop early problems w/ GI tract (GERD to dysphagia), heart(myocardial fibrosis), lungs (fibrosis & PAH),
& kidneys (malignant HTN)
o Complications can be rapid
● Limited cutaneous *Esophagus
o Skin thickening limited to sites distal to face, neck and distal extremities
o Organ changes rare or late
o CREST Syndrome
▪ Calcinosis – calcium deposits in tissues
▪ Raynaud’s Phenomenon – intermittent vasospasm of finger tips - first CREST symptom that develops
▪ Esophageal dysmotility - **Dysphagia**
▪ Sclerodactyly – scleroderma of digits – fingers stiff, shiny, and no skin folds
▪ Telangiectasia – capillary dilations that form vascular lesions on face, lips & fingers
● Medical Management
o Medications – Tx sx
▪ Vasoactive agents – CCB for Raynaud’s symptoms
▪ Anti – inflammatory meds - steroids
▪ Immunosuppressants
, Discoid lupusDiscoid lupus 4
o Reduce renal complications
