摘要
Background: The epidemiology of aminoglycoside-associated acute kidney injury (AG-AKI) has not been well described in pediatric patients with cystic fibrosis (CF). We aimed to assess the impact of daily serum creatinine (SCr) measurement on detection of AG-AKI at our institution. Methods: We examined a cohort of hospitalized patients with CF who received an intravenous (IV) aminoglycoside for %26gt;= 3 days. We compared the rate, timing, and medical management surrounding detection of AG-AKI during 2 periods: January 2010 May 2011 (Era 1, SCr measured at the discretion of the medical team, N = 124) and June 2011 June 2012 (Era 2, SCr measured daily, N = 103). Our primary outcome was detection of AG-AKI defined as %26gt;= 50% increase in SCr from baseline (lowest value in prior 6 months), or %26gt;= 0.3 mg/dL rise within 48 h, occurring after day 2. Results: The use of once daily tobramycin (p = 0.02) and IV fluids (p %26lt; 0.001) was higher during Era 2, while AG courses were shorter (p = 0.04), and fewer concomitant nephrotoxins (p = 0.04) were given; higher daily tobramycin doses (p %26lt; 0.001) were administered. Although the rate of AG-AKI was not significantly different (12% during Era 1 vs. 20% during Era 2, p = 0.09), the number of AG-AKI days detected increased (5.5 vs. 2.9 per 100 AG days, p = 0.003), and detection occurred earlier (median 6 vs. 9 days, log rank test p = 0.02) during the daily SCr period. Conclusions: Daily SCr measurement promoted earlier and increased detection of AG-AKI in patients with CF at our institution. We suggest systematic evaluation for AKI during aminoglycoside administration in patients with CF.
