Histone Antibodies

Immunology

Description

Histones are basic proteins which bind to DNA within the nuclei of cells. Anti-histone antibodies are found in patients with SLE and patients with DIL. In SLE, anti-histone antibodies do not provide any better diagnostic information than DNA and anti-nuclear antibodies but in drug induced lupus, a typical antibody profile consists of anti-nuclear antibodies, anti-histone antibodies but rarely dsDNA antibodies and extractable nuclear antibodies [1]. Drugs implicated in DIL include hydralazine, procainamide and isoniazid [1]. Histone antibodies can be positive in active lupus nephritis [2]. Anti-histone antibodies have also been reported in selected cases of rheumatoid arthritis. Anti-histone antibody levels are reportedly higher in neuropsychiatric lupus [3].
