Letter to the editor: a case of atheroembolic renal disease confirmed by skin biopsy and successfully treated with low-dose prednisone

On October 2015, an 81-year-old White man with clinical history of chronic kidney disease (CKD) stage 3b (sCr 1.6 mg/dL; eGFRMDRD 44 mL/min/1.73m2), type 2 diabetes mellitus, hypertension, dyslipidemia, and smoking habit was hospitalized for ST-elevation myocardial infarction. He underwent primary percutaneous coronary intervention (PCI) with transradial approach and placement of two drug-eluting stents (DES). Three days later, he had nonoliguric contrast-induced acute kidney injury with peak sCr 2.4 mg/dL, his kidney function was almost completely restored within 5 days (sCr 1.9 mg/dL). However, because of severe atherosclerotic disease, the first interventional procedure remained incomplete, and a second PCI was performed 7 days later by transfemoral approach with the placement of an additional DES. At the time of hospital discharge, sCr was comparable to basal values (1.6 mg/dL).
