Serum creatinine at presentation was highest on the day of first PEX ±7 days.5 The upper limit of normal for serum creatinine at the patients’ hospitals was 1.1-1.5 mg/dL.
eGFR, estimated glomerular filtration rate.

Ten of 78 patients died with their first episode, 2 were lost to follow-up, and 4 other patients did not have a follow-up serum creatinine measurement. Therefore, 62 patients are included in long-term follow-up data.
