Systemic Sclerosis Flashcards
what is systemic sclerosis
multisystem autoimmune disorder
what is systemic sclerosis characterised by
vasculopathy, autoimmunity and FIBROSIS
what symptoms can be seen in systemic sclerosis
classic symptoms of Raynaud’s, skin thickening, difficulty swallowing, GORD, telangiectasia, calcinosis, +/- SOB
what are the symptoms of Raynaud’s phenomenon, very common in systemic sclerosis patients
classically triphasic
blanching(white), acrocyanosis(purple/blue), reactive hyperaemia(redness)
what are some red flags in systemic sclerosis
raynaud’s + SOB, raynaud’s + telangiectasia, onset raynaud’s in mid/late adulthood, raynaud’s + skin complication
what is telangiectasia
small dilated blood vessels near surface of skin, also called spider veins
what are the 2 different subtypes of systemic sclerosis
diffuse cutaneous and limited cutaneous
describe diffuse systemic sclerosis
skin involvement on extremities ABOVE and BELOW elbows and knees, plus face and trunk
describe limited systemic sclerosis
skin involvement on extremities and only BELOW the elbows and knees
describe the pathophysiology of systemic sclerosis
disregulated chronic inflammation which drives fibrosis of blood vessels(vasculopathy), then causes connective tissue fibrosis which support the blood vessels and form extrinsic fibrosis around vessels
what are the important antibodies seen in systemic sclerosis
anticentromere, antitopoisomerase(anti-Scl-70) and anti-RNA polymerase(less important)
what other name did systemic sclerosis used to be called, and what does it mean
scleroderma, means thick skin
what antibodies are more common in diffuse and limited systemic sclerosis
diffuse = antitopoisomerase limited = anticentromere
describe the rate of progression of diffuse cutaneous and limited cutaneous systemic sclerosis
diffuse faster progression, more symptoms sooner
what face changes may be seen in systemic sclerosis
small “puckering” mouth, “beaked” nose, scleroderma, telangiectasia
