BACKGROUND: Immune checkpoint inhibitors (ICPis) are associated with multi-organ immune-related adverse effects. Here, we examined the incidence rate, recovery rate, and risk factors of acute kidney injury complicated with ICPis (ICPi-AKI) and evaluted the association between ICPi-AKI and mortality in Japanese patients.
METHODS: We analyzed 152 consecutive patients receiving ICPis between 2015 and 2019. A logistic regression analysis was performed to identify risk factors for ICPi-AKI incidence and Cox regression analysis was performed to evaluate the association between ICPi-AKI and mortality.
RESULTS: The mean patient age was 67 ± 10 years, with the median baseline serum creatinine level of 0.78 mg/dL. Twenty-seven patients (18%) developed ICPi-AKI, and 19 (73%) of them recovered. Pembrolizumab use and liver diseases were significant risk factors for the ICPi-AKI incidence. During the follow-up, 85 patients (59%) died, 17 patients (63%) with ICPi-AKI and 68 (54%) patients without ICPi-AKI, respectively. The ICPi-AKI incidence was not independently associated with mortality (adjusted hazard ratio, 0.85; 95% confidence intervals, 0.46-1.61).
CONCLUSIONS: Our finding suggest that pembrolizumab use and liver diseases are associated with a higher risk of ICPi-AKI development, but ICPi-AKI did not affect mortality. Future multi-center studies are needed to develop optimal management and prevention strategies for this complication in patients receiving ICPis.
