What is CENP antibodies?
Anti-SS-B and anticentromere protein (CENP) antibodies are used for the diagnosis of systemic lupus erythematosus, Sjögren’s syndrome, and systemic sclerosis. However, autoantibody production has also been reported in patients with various malignancies [2–10].
What disease are anti-centromere antibodies most often associated with?
Anti-centromere antibodies (ACAs) are detected in various autoimmune diseases such as Sjögren’s syndrome (SS), systemic sclerosis (SSc) and primary biliary cholangitis (PBC) and correlate with characteristic symptoms such as Raynaud’s phenomenon and sclerodactyly.
What are anti-centromere B antibodies?
Anti-centromere antibodies (ACAs; often styled solid, anticentromere) are autoantibodies specific to centromere and kinetochore function. They occur in some autoimmune diseases, frequently in limited systemic scleroderma (formerly called CREST syndrome), and occasionally in the diffuse form of scleroderma.
How serious is systemic sclerosis?
Sometimes systemic sclerosis worsens rapidly and becomes fatal (mainly with diffuse systemic sclerosis). At other times, it affects only the skin for decades before affecting internal organs, although some damage to internal organs (such as the esophagus) is almost inevitable. The course is unpredictable.
What antibodies are used for scleroderma?
Anticentromere antibody, also known as ACA, is present in people with limited scleroderma (and the test is positive in 20% of people with scleroderma). People with limited scleroderma have a low frequency of lung, heart, and renal disease.
What does anti centromere antibody positive mean?
A positive antinuclear antibody test does not always indicatethe presence of a connective tissue disease, but the presence of anticentromere antibody without systemic sclerosis or CREST often indicates the presence of another sometimes serious underlying rheumatic or connective tissue disease.
Is CREST syndrome life threatening?
Most patients have mild disease with annoying but not life-threatening disease. Scleroderma is treatable, resulting in a long and excellent quality of life….Limited Scleroderma – CREST Syndrome.
| C | (calcinosis) is for the calcium deposits under the skin and in tissues. |

| R | stands for Raynaud’s phenomenon. |
What does anti-centromere antibody positive mean?
What does a positive centromere mean?
A positive test for centromere antibodies is strongly associated with CREST syndrome. The presence of detectable levels of centromere antibodies may antedate the appearance of diagnostic clinical features of CREST syndrome by several years.
What is the life expectancy of someone with systemic scleroderma?
People who have localized scleroderma may live an uninterrupted life with only minor symptom experiences and management. On the other hand, those diagnosed with an advanced and systemic version of the disease have a prognosis of anywhere from three to 15 years.
What were your first symptoms of scleroderma?
Early symptoms may include swelling and itchiness. Affected skin can become lighter or darker in color and may look shiny because of the tightness. Some people also experience small red spots, called telangiectasia, on their hands and face.
