All of the Following can cause SLE like syndrome, except
**Core Concept**
Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease characterized by the production of autoantibodies and immune complex deposition in various organs, leading to inflammation and tissue damage. SLE-like syndromes can be induced by various factors, including medications, infections, and other diseases that mimic the clinical and immunological features of SLE.
**Why the Correct Answer is Right**
Several medications and infections can cause SLE-like syndrome by triggering autoantibody production or immune complex formation. For example, certain anticonvulsants, such as phenytoin, and anti-tuberculosis medications, like isoniazid, have been associated with SLE-like reactions. Infections like hepatitis B and C, as well as certain parasites like Toxoplasma gondii, can also induce SLE-like symptoms.
**Why Each Wrong Option is Incorrect**
* **Option A:** Certain medications, such as hydralazine and procainamide, are known to cause SLE-like syndrome. Therefore, option A is incorrect because it can indeed cause SLE-like syndrome.
* **Option B:** Infections like hepatitis B and C can induce SLE-like symptoms, making option B incorrect.
* **Option C:** This option is not provided, but typically, other diseases like Sjögren's syndrome, scleroderma, or rheumatoid arthritis can cause SLE-like symptoms, making this option incorrect if it were provided.
**Clinical Pearl / High-Yield Fact**
It is essential to distinguish between SLE and SLE-like syndromes, as the treatments and outcomes can differ significantly. Medications that are known to cause SLE-like reactions should be avoided or used with caution in patients with a history of autoimmune diseases.
**Correct Answer:** A.
