Drug induced SLE seen in
**Core Concept**
Drug-induced Systemic Lupus Erythematosus (SLE) is a rare but serious adverse effect of certain medications, which can mimic the clinical features of idiopathic SLE. This condition is characterized by the development of autoantibodies, particularly anti-histone antibodies, and clinical manifestations such as arthritis, rash, and nephritis.
**Why the Correct Answer is Right**
The pathogenesis of drug-induced SLE involves the formation of drug-induced antibodies, which can bind to and activate the immune system, leading to the production of autoantibodies and inflammation. Certain drugs, such as hydralazine, procainamide, and isoniazid, are known to be associated with the development of drug-induced SLE. These drugs can alter the immune response by increasing the expression of major histocompatibility complex (MHC) molecules on the surface of antigen-presenting cells, making them more recognizable by the immune system.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify a drug class or medication commonly associated with drug-induced SLE.
**Option B:** This option is incorrect because it is a type of idiopathic SLE and not a medication-induced form.
**Option C:** This option is incorrect because it is a type of idiopathic SLE and not a medication-induced form.
**Clinical Pearl / High-Yield Fact**
Certain medications, such as hydralazine and procainamide, are known to be associated with the development of drug-induced SLE. It is essential to consider these medications in the differential diagnosis of patients presenting with symptoms suggestive of SLE, especially if they have a recent history of medication use.
**Correct Answer: D. Penicillamine**
