What is the first-line treatment for acute interstitial nephritis?

• A. Administer antibiotics immediately
• B. Stop the offending agent and give steroids
• C. Increase hydration with intravenous fluids
• D. Initiate dialysis right away

Answer: (B)

Acute interstitial nephritis (AIN) is a condition characterized by inflammation of the kidney interstitium, often as a result of an allergic reaction to medications or infections. The first-line treatment for AIN primarily involves addressing the underlying cause of the condition. Stopping the offending agent is crucial, as this is often the trigger for the inflammatory process in the kidneys. Common culprits include non-steroidal anti-inflammatory drugs (NSAIDs), certain antibiotics, or diuretics. Once the offending medication is discontinued, the inflammation may begin to resolve. In many cases, the introduction of corticosteroids is also beneficial. Steroids help to reduce inflammation and support the resolution of AIN, particularly in cases that are moderate to severe. Therefore, stopping the offending agent and administering corticosteroids together is considered the most effective initial management strategy. This approach directly targets the underlying pathology, allowing for recovery of renal function and improvement in symptoms. Other options, such as increasing hydration with intravenous fluids, while possibly helpful for certain renal issues, do not address the inflammatory component of AIN. Dialysis is generally reserved for severe cases when renal function has significantly declined and cannot be managed conservatively. Initiating antibiotics immediately would only be indicated if there is a confirmed infectious
