The presence of PM/Scl-100 IgG antibody along with a positive ANA IFA nucleolar pattern is associated with connective tissue diseases such as polymyositis (PM), dermatomyositis (DM), systemic sclerosis (SSc. The antibodies are usually associated with positive ANA with nucleolar patterns. Anti-PM-Scl may be directed to different subunits in the PM-Scl complex, usually the 75 kD and 100 kD subunits. Anti-PM-Scl is often associated with Raynaud's phenomenon, arthritis, muscle aches and effects on the skin and lungs FAPMA : The anti-PM/Scl-100 antibody is associated with younger age, calcinosis and has lower rates of gastrointestinal symptoms, ILD and pulmonary hypertension. There is also evidence of a possibly better survival compared to the presence of either anti-PM/Scl-75 or anti-Scl-70 antibodies Although the sera of more patients with PM/scleroderma, scleroderma, PM, or DM have to be analyzed with the full-length PM-Scl-75 antigen, our data strongly suggest that, if only PM-Scl-100 is used in ELISAs, a significant number of patients will have negative test results because anti-PM-Scl-75 antibodies remain undetected

PM-Scl 100-kd protein was isolated and sequenced, with a predicted protein of 860 amino acids and molecular mass of 98.87 kd (7). A second cDNA encoding the PM-Scl 100-kd protein derived from HeLa cells has also been described, with a predicted protein of 885 aa, that was identical to the thymocyte form except for a 75-b The anti-PM/Scl-100 antibody is associated with younger age, calcinosis and has lower rates of gastrointestinal symptoms, ILD and pulmonary hypertension. There is also evidence of a possibly better survival compared to the presence of either anti-PM/Scl-75 or anti-Scl-70 antibodies If you are ANA negative by IF with a low positive Scl-70, it is almost always a false positive. However, there is one exception. If the lab uses a 1:80 cutoff for the ANA/IFA test, you could have a titer of 1:40 and in that case it is possible that the Scl-70 is very low because you are very early in the disease process. That is unlikely, however Scleroderma Antibodies and Clinical Relevance. Historically, systemic scleroderma was diagnosed as either diffuse or limited. The presence of anti-SCL-70 (anti-topoisomerase) antibodies is highly specific to the diagnosis of diffuse scleroderma, while the presence of anti-centromere antibodies is highly specific to the diagnosis of limited.

Anti-PM/Scl is associated with lung problems and an overlap of polymyositis and scleroderma. Children with PM-scleroderma overlap tend to have a strongly positive antinuclear antibody (ANA). HMGCR (3-hydroxy-3-methylglutaryl-coenzyme A reductase) is a key enzyme in the production of cholesterol Results Forty-one anti-PM/Scl-positive, 132 AS, 178 DM, and 135 IMNM patients were included. Although muscle weakness was a presenting feature in just 37% of anti-PM/Scl-positive patients, 93% eventually developed weakness.

The anti-PM-Scl antibodies can be further subdivided into two major subgroups, the anti-PM-Scl-75 [20] and the anti-PM-Scl-100 [21]. Anti-PM-Scl-75 antibodies are more common in patients with dcSSc and are associated with a higher prevalence of lung involvement, joint contractures and muscular atrophy than anti-PM-Scl-75 negative patients Background Anti-PM/Scl (a-PM/Scl) antibodies are found in different systemic autoimmune disease such as polymyositis, dermatomyositis, systemic sclerosis (SSc), and overlap syndromes. According to literature they are detected in about 2% of patients with SSc, but their presence are more common in SSc with myositis overlap. Features positively associated with the presence of a-PM/Scl antibodies. Forty-one anti-PM/Scl-positive, 132 AS, 178 DM, and 135 IMNM patients were included. Although muscle weakness was a presenting feature in just 37% of anti-PM/Scl-positive patients, 93% eventually developed weakness. Unlike the other groups, anti-PM-Scl-positive patients had more severe weakness in arm abductors than hip flexors PM-Scl 100/75 positive patients presented mostly a pulmonary fibrotic pattern (p <0.05) and, also, heart complications were more likely associated with anti PM-Scl 100/75 positivity (p <0.05). The. SCL70 : Scl 70 (topoisomerase 1) is a 100-kD nuclear and nucleolar enzyme. Scl 70 antibodies are considered to be specific for scleroderma (systemic sclerosis) and are found in up to 60% of patients with this connective tissue disease. Scl 70 antibodies are more common in patients with extensive cutaneous involvement and interstitial pulmonary fibrosis, and are considered a poor prognostic.

Another pattern, known as a nucleolar pattern, is common in people with scleroderma. The anti-double-stranded DNA antibody (anti-dsDNA) is a specific type of ANA antibody found in about 30% of people with systemic lupus. Less than 1% of healthy individuals have this antibody, making it helpful in confirming a diagnosis of systemic lupus All 4 cases were positive for anti-PM/Scl and eventually developed symptoms consistent with overlap SSc/myositis. Patient 1 was an 8-year-old white male who presented with diffuse hand swelling, tight skin, and contractures of the metacarpophalangeal (MCP) Extractable nuclear antigens (ENAs) include more than 100 different soluble cytoplasmic and nuclear antigens. The most commonly used ENA tests include tests for Smith, Sm/RNP (or U1 RNP), SSA-52 (Ro52), SSA-60 (Ro60), SSB, Scl-70 (topoisomerase 1), and Jo-1 antibodies. These are usually the first-line tests after a positive ANA result I am a forty year old women normally in good health. I received a positive result on two separate ANA tests (1:2560, homogeneous), which is apparently quite high. Subtest scores were all negative except Anti-scl-70 (2.0), anti-SM (1.1). I went to the doctor for the following symptoms: fatigue, anxiety, nausea, cold flashes. These symptoms came on all of a sudden and have persisted for three.

Originally, most PM/Scl-positive sera have been shown to contain anti-PM/Scl-100 and about 50% to 60% of the sera have been shown to react with PM/Scl-75 [11,12,44,45]. Raijmakers and colleagues showed that PM/Scl-75 contains a previously unidentified N-terminal region that is important for the antigenicity of the protein [ 46 ] The SCL-70 blood test is a specific test that is designed to produce specific results. Although it may not always be accurate and provide a negative result when scleroderma is present, a positive result can provide a diagnosis of this connective tissue disorder so that a treatment plan can begin.

EXOSC10 is a nucleolar protein and represents one crucial component of the so-called PM/Scl complex or nuclear exosome, which is an RNA-processing complex consisting of a number of exoribonucleases (not to be confused with certain multivesicular bodies which are shed by cultured cells into the culture fluid and are also called exosomes).Autoantibodies against EXOSC10 occur in patients. Exosome component 10 (EXOSC10), also named autoantigen PM/Scl 2, is the 100 kDa antigen component of PM-Scl and is recognized by most sera of PM-Scl paitents. EXOSC10 is strongly enriched in the nucleolus and a small amount has been found in cytoplasm supporting the existence of a nucleolar RNA exosome complex form PM or DM (with rash) or overlap myositis See text and Table 1 .
