Background: In the non-transplant setting, hyperchloremia has been associated with kidney injury. We sought to study the impact of serum chloride (SCl) on transplant outcomes.
Methods: We analyzed 936 living donor kidney transplants (LDKT) between '05-'17. A SCl on the day of transplant was compared to the SCl post-operative day 2 (POD2). The outcomes were 30-day eGFR and cellular rejection (ACR) within 90 days. A multivariate Cox Proportional Hazards model was performed. A multivariate linear regression was used to predict 30-day eGFR based on change in SCl.
Results: The average change in SCl on POD2 was an increase by 1.29 (0.95-1.64). Increasing SCl levels (from day of transplant to POD2) were associated with a decreased risk of 90-day ACR HR 0.92 (0.88-0.95, p<0.01). Additionally, 30-day eGFR increased by 0.45ml/min/1.73m2 (0.13-0.77, p=0.01) for each 1 unit increase in SCl on POD2.
Conclusion: A postoperative SCl increase was not associated with deleterious outcome in LDKT.
