Systemic Sclerosis Flashcards
define systemic sclerosis
An autoimmune connective tissue disorder involving inflammation and fibrosis of connective tissues, the skin, and organs.
what causes sclerosis
Caused by excess collagen production that leads to thickening and tightening of skin
is sclerosis more common in men or women
it is 4 times more commen in women
what is scleroderma
relates to the hardening of the skin (it may be used interchangeably with systemic sclerosis)
what is Limited Cutaneous Systemic Sclerosis (LCSS)
Also called CREST syndrome, this is a more limited version of systemic sclerosis.
what does CREST refer to
Calcinosis
Raynaud’s phenomenon
oEsophageal dysmotility
Sclerodactyly
Telangiectasis
what is Diffuse Cutaneous Systemic Sclerosis (DCSS)
A subtype that includes the CREST mnemonic plus cardiovascular, lung, and kidney problems.
signs and symptoms of sclerosis
- scleroderma (hardening of the skin, most notable on the hands and face)
- Sclerodactyly (skin tightening around joints, loss of the fat pads on fingers, and ulceration/breaking of the skin surface).
- Telangiectasia (dilated blood vessels in the skin, measuring less than 1mm in diameter)
- Calcinosis (calcium deposits under the skin, especially on the fingertips)
- Oesophageal dysmotility
- Systemic and pulmonary hypertension (caused by connective tissue dysfunction)
- Pulmonary fibrosis
- Scleroderma renal crisis (medical emergency, with severe hypertension and renal failure)
what is telangiectasia

what is sclerodactyly

what is calcinosis
calcium deposits under the skin, especially on the fingertips)
how to diagnose sclerosis
using the American College of Rheumatology/European League Against Rheumatism classification criteria.
These consider clinical features, antibodies, and nailfold capillaroscopy:
which antibodies are present in sclerosis
- ANAs present in most patients
- Anti-centromere antibodies are most associated with LCSS
- Anti-Scl-70 antibodies are most associated with DCSS and more severe disease.
what is Nailfold Capillaroscopy
A test to examine the peripheral capillaries.
