SLE-related illnesses Flashcards
3 SLE related illnesses
Polymyositis/Dermatomyositis
Sjögren’s syndrome
Sarcoidosis
what are polymyositis and dermatomyositis?
idiopathic inflammatory myopathies:
-muscle inflammation leading to weakness
polymyositis vs dermatomyositis
PM: just muscle (proximal first)
DM: muscle AND skin , rashes
Amyopathic dermatomyositis (ADM)
Rash only, no muscle involvement (newly described and uncommon)
polymyositis and dermatomyositis: women or men more?
women
clinical presentation of muscle weakness from PM/DM?
Usually painless
Can’t climb stairs or lift arms to do hair
Trouble swallowing
4 characteristic skin manifestions of DM
- Heliotrope rash (purple around eyes)
- Malar rash (looks like SLE)
- Shawl sign – photsensitization of skin (scarf around neck rash)
- Gottron’s papules – over PIP and MCP
*diffuse redness on face + Possible Raynaud phenomenon
Labs for DM/PM:
+ ANA
CK (creatine kinase- muscle breakdown) - HIGH
adolase (converts glucose to energy)- HIGH
what do you need to dx DM/PM?
Muscle Bx: shows inflammation
Txt for DM/PM
Steroids high dose
Methotrexate- longterm
Azathioprine - longterm
polymyositis (PM) vs polymyalgia rheumatica (PMR)
PM: can’t get up b/c weakness
PMR: can’t get up b/c of pain
Sjögren’s disease (A.K.A. Sicca)
Autoantibodies directed against exocrine glands,
Most affected are lacrimal and salivary glands, with inflammatory destruction of glands
(can be primary to secondary to other autoimmune d/o)
3 presenting symptoms of SICCA
- dry eye (xerophthalmia)
- dry mouth (xerostomia)
- parotid gland enlargement (trying to produce more alive = hypertrophy)
txt options for SICCA
mostly symptomatic, avoiding anticholinergic drugs
- artificial tears
- restasis aka cyclosporine (immunesuppresant)
- silicone sporine ducts to keeps tears in eye and not draining into nose
primary or secondary SICCA more common ?
what does secondary come from?
uncommon: primary
Common: secondary to other connective tissue disorder
RA, SLE, polymyositis, scleroderma
