Distribution of autoimmune diseases and autoantibodies against extractable nuclear antigens (anti-ENA).

AD in Anti-ENA-positive patients	Antigens found
SLE (9/27)	SS-A (Ro), SS-B (La), Smith, Scl-70, NUC, dsDNA, RNP/Smith
Scleroderma (4/27)	SS-A (Ro), Scl-70, CENP-B
Sjögren’s syndrome (3/27)	SS-A (Ro), SS-B (La)
Polymyositis (2/27)	SS-A (Ro), Smith, Scl-70, RNP/Smith
Behçet’s disease (1/27)	SS-A (Ro)
Rheumatoid arthritis (1/27)	SS-A (Ro), SS-B (La), Smith, Scl-70, CENP-B, Jo-1, RNP/Smith
Autoimmune hemolytic anemia (1/27)	NUC
Autoimmune hepatitis and scleroderma (1/27)	CENP-B
SLE and scleroderma (1/27)	Scl-70
SLE and polymyositis (1/27)	RNP/Smith
SLE, MCTD and scleroderma (1/27)	RNP/Smith
SLE and Evans syndrome (1/27)	NUC
SLE and Sjögren’s syndrome (1/27)	SS-A (Ro), Smith, RNP/Smith

SLE = systemic lupus erythematosus.
MCTD = mixed connective tissue disease.
