Abstract

Background: We provide detailed analysis and outcomes in patients post-kidney transplant (KT) developing ascites, which has never been categorically reported. Methods: Ascites was identified by ICD9/10 codes and detailed chart review in patients post-KT from 01/2004-06/2019. The incidence of patient death and graft loss were determined per 100-person-years, and the incidence rate ratio was obtained. Results: Of 3329 patients receiving KT, 83 (2.5%) patients had new-onset ascites, of whom 58% were male, 21% blacks, and 29% whites. Seventy-five percentage were on hemodialysis. Patients were maintained primarily on tacrolimus and mycophenolate for immunosuppression. Only 14% of patients with ascites had the appropriate diagnostic workup. There was a trend toward an increased mortality in patients with ascites (incidence rate ratio, IRR [95% CI]: 1.8 [0.92, 3.19], p =.06), and a significantly higher incidence of graft loss (IRR: 5.62 [3.97, 7.76], p <.001), compared with non-ascites patients. When classified by ascites severity, determined by imaging, moderate/severe ascites patients had the worst clinical outcomes, with a mortality of 32% and graft failure in 57%, compared with 9% and 10%, respectively, in those without ascites. Conclusion: In this large cohort employing stepwise analysis of ascites post-KT, worse outcomes were noted, dictating the need for optimized management to improve clinical outcomes.
