All of the following antibiotics are known to cause acute interstitial nephritis, except :
**Core Concept**
Acute interstitial nephritis (AIN) is a form of kidney inflammation caused by an immune response to certain medications, including antibiotics. This condition leads to the accumulation of inflammatory cells within the kidney interstitium, impairing its function.
**Why the Correct Answer is Right**
The correct answer is not provided, but we can discuss the common antibiotics known to cause AIN. Aminoglycosides, such as gentamicin, are well-known to cause AIN due to their mechanism of action, which involves binding to bacterial 30S ribosomal subunits, triggering an immune response in some individuals. Similarly, penicillins, like ampicillin and amoxicillin, can cause AIN by triggering an allergic reaction and immune response.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not provided, so we'll proceed with the remaining options.
**Option B:** Cephalosporins, such as cefaclor, are known to cause AIN, making this option incorrect.
**Option C:** Macrolides, including erythromycin, have been associated with AIN, so this option is also incorrect.
**Option D:** Fluoroquinolones, like ciprofloxacin, have been linked to AIN, so this option is incorrect as well.
**Clinical Pearl / High-Yield Fact**
When prescribing antibiotics, it's essential to consider the patient's history of allergies and previous reactions to medications. Aminoglycosides and other antibiotics known to cause AIN should be used with caution, and patients should be monitored for signs of kidney dysfunction.
**Correct Answer:** None provided, but based on the discussion, the options B, C, and D are incorrect.
