Furthermore, anti-histone antibodies can also be positive in drug-induced lupus. [citation needed] Anti-Histone antibodies are positive in up to 95% of patients with drug induced lupus. The most common medications associated with drug induced lupus are hydralazine, procainamide, isoniazid, methyldopa, chlorpromazine, quinidine, and minocycline. [9]
A value of greater than 1.5 units relative to a control serum is considered a positive ELISA test for the anti-histone antibodies. Patients with drug-induced lupus erythematosus typically have positive tests for anti-histone antibodies but do not have indications for anti-dsDNA antibodies. Patients with idiopathic systemic lupus erythematosus ...
Subtypes of antinuclear antibodies include anti-Smith and anti-double stranded DNA antibodies (which are linked to SLE) and anti-histone antibodies (which are linked to drug-induced lupus). Anti-dsDNA antibodies are highly specific for SLE; they are present in 70% of cases, whereas they appear in only 0.5% of people without SLE. [13]
Lupus erythematosus is a collection of autoimmune diseases in which the human immune system becomes hyperactive and attacks healthy tissues. [1] Symptoms of these diseases can affect many different body systems, including joints , skin , kidneys , blood cells , heart , and lungs .
Certain chemical agents and drugs can also be associated with the genesis of autoimmune conditions, or conditions that simulate autoimmune diseases. The most striking of these is the drug-induced lupus erythematosus. Usually, withdrawal of the offending drug cures the symptoms in a patient.
An autoantibody is an antibody (a type of protein) produced by the immune system that is directed against one or more of the individual's own proteins. Many autoimmune diseases (notably lupus erythematosus ) are associated with such antibodies.
Halsey announced in a June 5 Instagram post that she has lupus, an autoimmune disease which was diagnosed in 2022, and a rare white blood-cell disorder. In a prior post announcing the release of ...
Many drugs are known to cause drug induced lupus and they produce various antigenic targets within the nucleosome that are often cross reactive with several histone proteins and DNA. Procainamide causes a form of drug-induced lupus that produces antibodies to the histone H2A and H2B complex. [40] [41]
