Background: Steatotic grafts are increasingly being used for liver transplant (LT); however, the impact of graft steatosis on renal function has not been well described. Methods: A total of 511 allografts from Mayo Clinic Arizona and Minnesota were assessed. We evaluated post-LT acute kidney injury (AKI) patterns, perioperative variables and one-year outcomes for patients receiving moderately steatotic allografts (>30% macrovesicular steatosis, n = 40) and compared them to non-steatotic graft recipients. Results: Post-LT AKI occurred in 52.5% of steatotic graft recipients versus 16.7% in non-steatotic recipients (p < 0.001). Ten percent of steatotic graft recipients required new dialysis post-LT (p = 0.003). At five years, there were no differences for AKI vs. no AKI patient survival (HR 0.95, 95% CI 0.08–10.6, p = 0.95) or allograft survival (HR 1.73, 95% CI 0.23–13.23, p = 0.59) for those using steatotic grafts. Lipopeliosis on biopsy was common in those who developed AKI (61.0% vs. 31.6%, p = 0.04), particularly when the Model for End-Stage Liver Disease (MELD) was ≥20 (88.9%; p = 0.04). Lipopeliosis was a predictor of post-LT AKI (OR 6.0, 95% CI 1.1–34.6, p = 0.04). Conclusion: One-year outcomes for moderately steatotic grafts are satisfactory; however, a higher percentage of post-LT AKI and initiation of dialysis can be expected. Presence of lipopeliosis on biopsy appears to be predictive of post-LT AKI.
Objective: Evaluate the peri-implant soft tissue esthetics following a single, immediately provisionalized, delayed implant with/-out subepithelial connective tissue graft (SCTG).Material and Methods: The eligible patients were randomized into two groups.Immediate provisionalization was performed with (test group: SCTGG) or without SCTG (control group: NGG). The soft tissue esthetics was assessed by Pink Esthetic Score (PES) and Mucosal Scarring Index (MSI), at 6 and 12 months, following final implant restoration.
Results:The SCTGG, compared to NGG, yielded a 0.2 increased PES at 12 months (95% confidence interval (CI): À1, 1.4) and a 0.2 decreased MSI score (95% CI À0.9, 0.5) with no statistically significant differences in PES and MSI between both groups (p > 0.05).
Conclusion:Soft tissue grafting around immediately provisionalized delayed implants could exhibit comparable results to immediate provisionalization alone in terms of peri-implant soft tissue esthetics using PES and MSI (ClinicalTrials.gov Identifier: NCT03770975).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
