This study assessed the incidence and clinical characteristics of AKI in ARDS patients and found that age, diabetes, CKD, disease severity, lactate levels, and ECMO support were risk factors for AKI. Early AKI was related to underlying disease and severity of hospital admission, while late AKI was related to nephrotoxic drugs. The mortality rate was significantly higher in ARDS patients with AKI.
BackgroundWe assessed the incidence and clinical characteristics of acute kidney injury (AKI) in acute respiratory distress syndrome (ARDS) patients and its effect on clinical outcomes. MethodsWe conducted a single-center prospective longitudinal study. Patients who met the Berlin definition of ARDS in the medical ICU in China-Japan Friendship Hospital from March 1, 2016, to September 30, 2020, were included. AKI was defined according to the KDIGO clinical practice guidelines. Early and late AKI were defined as AKI occurring within 48 h after ARDS was diagnosed or after 48 h, respectively. ResultsOf the 311 ARDS patients, 161 (51.8%) developed AKI after ICU admission. Independent risk factors for AKI in ARDS patients were age (OR 1.027, 95% CI 1.009-1.045), a history of diabetes mellitus (OR 2.110, 95%CI 1.100-4.046) and chronic kidney disease (CKD) (OR 9.328, 95%CI 2.393-36.363), APACHE II score (OR 1.049, 95%CI 1.008-1.092), average lactate level in the first 3 days (OR 1.965, 95%CI 1.287-3.020) and using ECMO support (OR 2.359, 95%CI 1.154-4.824). Early AKI was found in 91 (56.5%) patients and late AKI was found in 70 (43.5%). Early AKI was related to the patient's underlying disease and the severity of hospital admission, while late AKI was related to the application of nephrotoxic drugs. The mortality rate of ARDS combined with AKI was 57.1%, which was independently associated with shock (OR 54.943, 95%CI 9.751-309.573). ConclusionA significant number of patients with ARDS developed AKI, and the mortality rate for ARDS patients was significantly higher when combined with AKI. Therapeutic drug monitoring should be routinely used to avoid drug toxicity during treatment.
