Risk factors of chronic kidney disease in cisplatin-based hyperthermia intraperitoneal chemotherapy.

PURPOSE: Cisplatin is commonly prescribed in hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal malignancy. Acute kidney injury (AKI) is regarded as a common complication after HIPEC combined with cytoreductive surgery (CRS). However, post-HIPEC chronic kidney disease (CKD) is scarce and less investigated. This study aims to investigate the incidence of CKD following cisplatin-based HIPEC and to analyse the associated risk factors. MATERIALS AND METHODS: From January 2016 to August 2021, a total of 55 patients treated with CRS and cisplatin-based HIPEC for peritoneal carcinomatosis were categorized retrospectively into groups, with and without CKD. Demographics, comorbidity, surgery, postoperative management, and complications were collected to evaluate risk factors for cisplatin-based HIPEC-related CKD. Univariate and multivariate analyses were conducted to confirm the correlation between different variables and CKD occurrence. RESULTS: Of the 55 patients, 24 (43.6%) patients developed AKI and 17 (70.8%) patients of these AKI patients progressed to CKD. Multivariate regression analysis identified intraoperative use of parecoxib (Odds Ratio (OR) = 4.39) and intraoperative maximum temperature > 38.5°C (OR = 6.40) as major risk factors for cisplatin-based HIPEC-related CKD occurrence. Though type II diabetes mellitus and intraoperative complications were the independent risk factors of AKI following cisplatin-based HIPEC, but they were not shown in CKD analysis. CONCLUSION: Intraoperative use of parecoxib during cisplatin-based HIPEC emerged as a significant risk factor for postoperative CKD. Clinicians should exercise caution in prescribing parecoxib during HIPEC procedures. Additionally, maintaining intraoperative body temperature below 38.5°C might be crucial to mitigate the risk of CKD development. This study underscores the importance of identifying and preventing specific risk factors to improve long-term renal outcomes in patients undergoing cisplatin-based HIPEC.

Joint Longitudinal Low Calcium High Phosphorus Trajectory Associates with Accelerated Progression, Acute Coronary Syndrome and Mortality in Chronic Kidney Disease.

The effects of long-term disturbance of the mineral metabolism on patients with chronic kidney disease (CKD) are unclear. We investigated whether the longitudinal Ca-P (joint calcium and phosphorus) trajectories are associated with incident end-stage renal disease (ESRD), acute coronary syndrome (ACS), and all-cause mortality in patients with CKD. We conducted a prospective cohort study by using data from a 13-year multidisciplinary pre-ESRD care registry. The final study population consisted of 4,237 CKD patients aged 20-90 years with data gathered from 2003 to 2015. Individuals' Ca-P trajectories were defined using group-based multi-trajectory modeling into three distinct patterns: reference, moderately abnormal, and severely abnormal. Times to ESRD, ACS, and death were analyzed using multiple Cox regression. Compared with those with a "reference" Ca-P trajectory, the adjusted hazard ratios (aHRs) (95% confidence interval [CI]) for incidental ESRD were 5.92 (4.71-7.44) and 15.20 (11.85-19.50) for "moderately abnormal" and "severely abnormal" Ca-P trajectories, respectively. The corresponding aHRs for ACS were 1.94 (1.49-2.52) and 3.18 (2.30-4.39), and for all-cause mortality, they were 1.88 (1.64-2.16) and 2.46 (2.05-2.96) for "moderately abnormal" and "severely abnormal" Ca-P trajectories, respectively. For outcomes of progression to ESRD, the detrimental effects of abnormal Ca-P trajectories were more substantial in patients with CKD stage 3 than those with CKD stage 4 or 5 (p-value for interaction < 0.001). Future studies should validate reliable longitudinal cut-offs of serum phosphorus and consider the "lowering phosphorus- the lower the better, the earlier the better" approach to phosphorus control in CKD.
