3/n the exposure to vitC raised concerned about oxalate nephropathy, so we proceeded to perform 🔬#UrineMicroscopy: no crystals, but massive “muddy” brown granular casts. Unexpected! Kinda #UrinarySediment we often encounter in the ICU, not in clinic

5/n 2 wks later, off ARB, off vitC: Cr 3.9, unchanged. UPCR 0.9. And #UrinarySediment still shows MBGC, scattered CaOx crystals in casts. So strong suspicion to AKI over CKD remains (versus brushing off the Cr rise as CKD progression)

8/n so, we are left with an unexplained ATI with massive presence of MBGCs. Time to regroup and reconsider culprits. Med list: Tessalon? Nope, not reported. What about Crestor? Can it cause ATI without causing rhabdo? Back to Pubmed “rosuvastatin acute tubular”:

9/n found this AJKD paper reporting biopsy-proven ATI 2/2 rosuvastatin without rhabdo pubmed.ncbi.nlm.nih.gov/27856086/

11/n the next step was obvious: stopping Crestor and reassessing, but before doing so, we triple checked urine🔬: unchanged, massive MBGC

15/n there is evidence of ⬇️of receptor-mediated endocytosis in renal tubules by HMG-CoA reductase inhibitors. But we still lack full understanding of the ATI pathogenesis. Maybe pharmacogenetic factors play a role. For now, be vigilant of Crestor. pubmed.ncbi.nlm.nih.gov/15339974/ Fin
