“…The combined use of nonsteroidal anti-inflammatory drugs (NSAIDs) (14,74), antibiotics (83), vitamin K antagonist fluindione (54, 74), RAASi (18,51) and diuretics (55,74) in cancer patients will increase the risk of ICI-AKI (21). In addition, acid inhibitors, including proton pump inhibitors (PPIs) (14,57,76) and histamine H2-receptor antagonists (H2RAs), reduce the therapeutic effect of ICIs and increase the risk of AKI (84). In the study by Chen et al, although the use of PPIs and NSAIDs were both risk factors for all-cause AKI and ICI-AKI, the odds ratio (OR) was higher for ICI-AKI than for all-cause AKI (1.77 vs. 2.42, 1.77 vs. 2.57, respectively) (85).…”
