Comments: Extractable nuclear antibodies (precipitating antibodies) have definitive diagnostic information. Precipitating antibodies to soluble tissue antigens are present in diverse rheumatic diseases: anti-Sm is highly specific for SLE; anti-nRNP (nuclear ribonucleoprotein) is present in SLE and overlap syndromes with scleroderma and polymyosities; anti=Scl-70 is highly specific for scleroderma; anti-Ro and anti-La are associated with SLE and Sjogren’s syndrome; anti-P is a new specificity related to psychosis in SLE patients as well as patients with nephritis and unexplained hepatitis; anti-Jo-1, anti-PM-Scl and anti-Mi-2 may be seen in polymyositis patients.
