Prophylactic hydration to protect renal function from intravascular iodinated contrast material in patients at high risk of contrast-induced nephropathy (AMACING): a prospective, randomised, phase 3, controlled, open-label, non-inferiority trial, Lancet  online 170221

The AMACING study found no prophylaxis to be non-inferior to prophylactic intravenous hydration in the prevention of contrast-induced nephropathy, as well as cost-saving. Additionally, we noted that hydration by itself sometimes leads to complications. This is a substantial problem, considering the 6–12 million high-risk patients that undergo procedures with intravascular iodinated contrast administration every year worldwide. Based on these findings and assuming optimal contrast media administration, withholding prophylaxis for high-risk patients with eGFR higher than 29 mL per min/1·73 m2 might be considered without compromising patient safety.

Conclusion: In the largest well-controlled study of acute kidney injury following contrast administration in the ED to date, intravenous contrast was not associated with an increased frequency of acute kidney injury.

Conclusion: We found no significant differences in our principal study outcomes between patients receiving contrast-enhanced CT versus those receiving noncontrast CT. Given similar frequencies of acute kidney injury in patients receiving noncontrast CT, other patient- and illness-level factors, rather than the use of contrast material, likely contribute to the development of acute kidney injury.
