The amoxicillin is therefore changed to cephalexin for an additional week. The rash resolves, but she returns complaining of fatigue, flank pain, and fever that has persisted despite the resolution of the sinusitis. She has a history of essential hypertension, hyperlipidemia, and gastric reflux. She has been on a stable regimen of lisinopril, simvastatin, and omeprazole. Today, her vital signs reveal: temperature 37.9C 100.2F, blood pressure 14590 mm Hg, regular pulse 75min, and respirations 16min. The physical examination is unremarkable. Serum urea and creatinine are elevated. Urinalysis shows leukocyturia, but urine bacterial culture is negative. A urine cytospin stained with Hansels solution reveals 3 binucleated cells with eosinophilic, granular cytoplasm. Which of the following is the most likely diagnosis?? A: Acute interstitial nephritis, B: Acute glomerulonephritis, C: Acute tubular necrosis, D: Acute vascular injury, E: IgA nephropathy,  <response>: This is a clinical case scenario describing a 62-year-old woman who developed a macular rash after taking amoxicillin for acute sinusitis. The rash resolved after switching to cephalexin but she later returned with fatigue, flank pain, fever, elevated serum urea and creatinine, leukocyturia, and binucleated cells on urine cytology. The history of recent amoxicillin use followed by rash, and now acute kidney injury with eosinophiluria makes acute interstitial nephritis the most likely diagnosis. The other choices can be ruled out:- Acute glomerulonephritis is unlikely with no evidence of hematuria or proteinuria. - Acute tubular necrosis would not cause eosinophiluria.- Acute vascular injury would not cause eosinophiluria.- IgA nephropathy would not be associated with recent amoxicillin use.A: Acute interstitial nephritis
