IMID/CTD Flashcards
(141 cards)
Another term for Progressive Systemic Sclerosis?
Scleroderma
What are the types of Scleroderma?
- Systemic - Diffuse cutaneous, Limited cutaneous (CREST), Overlap.
- Localized - Morphea or Linear Scleroderma.
- Not Systemic.
What is the difference b/t Diffuse and Localized Cutaneous Scleroderma?
Localized often only affects the skin and not other major organs, it is also non-progressive thickening; whereas, diffuse affects the skin, tissue underneath incl. blood vessels and major organs.
What is Overlap type Scleroderma?
diffuse or limited scleroderma w/features of another CTD (SLE, PM, DM).
Rare (autoimmune) chronic connective tissue disease that causes hardening and tightening of she skin and connective tissues?
Scleroderma.
What is another name for Limited Scleroderma and what does it stand for?
“CREST” - mnemonic for Signs/Sx.
- Calcinosis - calcium deposits in the skin.
- Raynaud’s Phenomenon.
- Esophageal Dysfunction - acid reflux and decrease in motility of esophagus.
- Slcerodactyly - thickening and tightening of the skin on the fingers and hands.
- Telangiectasias - dilation of capillaries causing red marks on surface of skin.
What is Sjogren’s (Show-grins) Syndrome?
An autoimmune disorder characterized by infiltration of lymphocytes into the exocrine glands.
What is the pathogenesis of Sjogren’s Syndrome?
Lymphocytes infiltrate and destroy exocrine glands, especially the lacrimal and salivary glands.
What are the main manifestations of Sjogren’s Syndrome?
Dry eyes/gritty sensation in eyes and dry mouth.
- Sx must be ongoing for at least 3 months.
- Other possible Sx – many:
- -dry skin/rashes.
- -joint pain, swelling.
- -persistent dry cough.
- -Lymphadenopathy.
- -Fatigue.
Epidemiology of Scleroderma?
- 1/10,000.
- peak onset 45-65 y/o.
- F:M of 3:1.
- More severe in AAs.
What is Polymyositis?
Inflammatory muscle disease characterized by PAINLESS, symmetrical proximal muscle weakness.
Common features of Polymyositis?
- Insidious onset.
- Painless.
- Dysphagia (30%).
- Arthralgias.
- LE weakness usually >UE.
- Constitutional Symptoms.
Who gets Polymyositis?
F:M of 2:1, AA:White of 5:1, usually >20 y/o (most often Dx at 46-60), associated w/cancers.
What do pt’s w/Polymyositis have difficulty with?
Kneeling, climbing stairs, lifting arms overhead, arising from a seated position, holding head up (severe).
What is Vasculitis?
An inflammation of the blood vessels in the body where the immune system mistakenly attacks the body’s own blood vessels, causing them to become inflamed.
What happens when a blood vessel becomes inflamed?
The blood vessels will narrow making it more difficult for blood to get through, they can close off completely (occlusion); in rare cases, stretch or weaken so much that they bulge (aneurysm) and possibly burst (aneurysm rupture).
What are the classifications of Vasculitis?
- Large-vessel: involve the aorta and it’s branches.
- Medium-vessel: affect medium-size and small arteries of the kidneys, liver, heart, etc.
- Small-vessel: predominantly targets capillaries and post-capillary venules.
What is the most common large-vessel vasculitis in humans?
Giant Cell Arteritis (mean age 74).
Typical Signs of Systemic Vasculitis of large vessels?
Limb claudication, asymmetric blood pressures, absence of pulses, bruits, aortic dilatation.
Typical Signs of Systemic Vasculitis of medium vessels?
Cutaneous nodules, ulcers, livedo reticularis, digital gangrene, mononeuritis multiplex, microaneurysms.
Typical Signs of Systemic Vasculitis of small vessels?
Purpura, vesiculobullous lesions, urticaria, glomerulonephritis, alveolar hemorrhage, cutaneous extravascular necrotizing granulomas, splinter hemorrhages, scleritis/episcleritis/uveitis.
When would you suspect vasculitis?
Constitutional Symptoms, arthralgias/myalgias, uncontrollable asthma/sinus issues for years, palpable purpura (small vessel), non-palpable purpura, hemorrhagic bulla, ulcers/erosions, urticaria (minimal pruritus).
What does IMID/CTD stand for?
Immune-mediated Inflammatory Disorders/Connective Tissue Disorders
What are the common IMID/CTD disorders?
- Rheumatoid Arthritis (RA).
- Spondyloarthritis
- -Psoriatic Arthritis.
- -Ankylosing Spondylitis.
- -Reactive (Reiter’s Arthritis).
- -IBD-arthritis. - PMR – Polymyalgia Rheumatica.
- SLE.
- Scleroderma.
- Sjogren’s Syndrome.
- Polymyositis/Dermatomyositis.
- Vasculitis - GCA, etc.
