Acute Interstitial Nephritis (AIN) | Causes, Pathophysiology, Symptoms, Diagnosis, Treatment

The video tutorial covers acute interstitial nephritis (AIN), a renal condition causing rapid decline in kidney function. It accounts for 10-20% of acute kidney injuries and is often non-oliguric. AIN can be caused by medications, infections, systemic conditions, or idiopathic factors. The pathophysiology involves immune responses triggered by drugs or infections. Clinical features include asymptomatic cases, nausea, vomiting, and specific lab findings like sterile pyuria. Diagnosis involves urinalysis and blood work, with kidney biopsy for definitive diagnosis. Treatment focuses on removing the offending agent and using corticosteroids.
