Pre-existing iron deficiency anemia and long-term risk of recurrent acute kidney injury in survivors of ICU-associated AKI: a propensity-matched study (opens in new tab)

BackgroundRecurrent acute kidney injury (rAKI) is a common complication among critically ill patients and is associated with progressive renal deterioration and increased long-term morbidity. Iron deficiency anemia (IDA) may compromise renal adaptive responses through impaired oxygen delivery and cellular energetics; however, whether pre-existing IDA is associated with rAKI risk remains unclear.MethodsWe conducted a propensity score-matched retrospective cohort study using the TriNetX databas...
