Evaluation of Cisplatin-Induced Acute Kidney Injury in Patients Co-Prescribed Serotonin Receptor Antagonists: A Retrospective Analysis

Cisplatin is an effective first line therapy for a variety of cancers. Cisplatin is highly emetogenic and resulting volume depletion can contribute to acute kidney injury (AKI). Anti-emetic drugs such as 5-hydroxytryptamine type 3 receptor antagonists (5-HT3RAs) are commonly prescribed to prevent th...

Description
Summary:Cisplatin is an effective first line therapy for a variety of cancers. Cisplatin is highly emetogenic and resulting volume depletion can contribute to acute kidney injury (AKI). Anti-emetic drugs such as 5-hydroxytryptamine type 3 receptor antagonists (5-HT3RAs) are commonly prescribed to prevent this complication. Preclinical studies suggest first generation 5-HT3RAs may alter the renal clearance and increase cisplatin toxicity. This retrospective study evaluated whether different 5-HT3RAs modify the risk of AKI in patients receiving cisplatin. Patients with cancer who received cisplatin between January 1, 2010 and December 31, 2016 were included. Patients over 18 years old with available data for baseline and post-treatment serum creatinine, cisplatin cumulative dose, and administration of 5-HT3RAs including first generation (ondansetron, granisetron, and ramosetron) and second generation (palonosetron) were analyzed. AKI defined as 1.5x increase in serum creatinine. Fisher's exact and Wilcoxon rank-sum tests were used to assess univariable associations between baseline covariates and AKI, and logistic regression for multivariable associations with AKI. Of 8703 patients identified with cisplatin exposure, 6889 were included. A total of 3881 (56.3%) patients received at least one 5-HT3RA, including palonosetron (3750, 54.4%), ondansetron (1399, 20.3%) and granisetron (11, 0.2%). AKI developed in 1666 (24.2%) patients following cisplatin. Patients who received any 5-HT3RAs were less likely to experience AKI as compared to patients that did not (22.6% vs 26.2%, p=0.001). Older age, male gender, African ethnicity, and cumulative cisplatin dose were univariately associated with higher risk for AKI (P
