Background: Saline hydration with addition of mannitol have commonly been the strategy to avoid cisplatin induced acute kidney injury (AKI). While the initial reports demonstrated that mannitol diuresis decreased cisplatin induced renal injury, others have shown renal injury to be worsened. Objective: To compare the risk of AKI in cancer patients receiving high dose cisplatin with and without addition of mannitol. Method: This was an ambispective cohort study based on consecutive sampling at Cipto Mangunkusumo General Hospital (CMGH) and Mochtar Riady Comprehensive Cancer Centre (MRCCC) Siloam Hospitals. The data was obtained from September 2017 to February 2018. The choice of mannitol administration based on attending physician clinical judgement. The primary outcome was increase of serum creatinine more than 0.3 mg/dL or 1.5 times from baseline. Analysis was done by using univariate, bivariate and multivariate logistic regression to obtain crude risk ratio and adjusted risk ratio of cisplatin induced AKI probability caused by mannitol addition on top of usual saline hydration protocol. Result: Data from 110 patients (57.3% male) with a median age of 44.5 years (range 19 to 60 years) were collected; 63 received saline with the addition of mannitol and 47 received saline only. Incidence of AKI were higher in mannitol vs saline only group. Bivariate analysis showed higher probability of post chemotherapy AKI in mannitol group, however it was statistically insignificant (RR 2.168; 95% CI 0.839–5.6; p = 0.094). On multivariate analysis the age adjusted RR was 2.852 (95% CI 0.68–11.96; p = 0.152). Conclusion: The addition of mannitol to hydration did not reduce the risk of cisplatin induced AKI as compared with saline hydration only. It was also found that risk for acute kidney injury were higher in population ≥ 40 years old.
