Sarcopenia and sarcopenic obesity is seen in a significant number of patients with cirrhosis undergoing LT evaluation. Sarcopenia progresses after LT initially and does not recover at least within the first year after surgery. Obesity is an independent predictor of pretransplant sarcopenia and NASH was associated with 6-fold increased risk of having sarcopenic obesity in cirrhotic patients in our cohort.
Polyomavirus nephropathy (PVN) remained inadequately classified until 2018 when the Banff Working Group published a new 3‐tier morphologic classification scheme derived from in‐depth statistical analysis of a large multinational patient cohort. Here we report a multicenter “modern‐era” validation study that included 99 patients with definitive PVN transplanted post January 1, 2009 and followed the original 2018 study design. Results validate the PVN classification, that is, the 3 PVN disease classes predicted clinical presentation, allograft function, and outcome independent of therapeutic intervention. PVN class 1 compared to classes 2 and 3 was diagnosed earlier (16.9 weeks posttransplant [median], P = .004), and showed significantly better function at 24 months postindex biopsy (serum creatinine 1.75 mg/dl, geometric mean, vs class 2: P = .037, vs class 3: P = .013). Class 1 presented during long‐term follow‐up with a low graft failure rate: 5% class 1, vs 30% class 2, vs 50% class 3 (P = .009). Persistent PVN was associated with an increased risk for graft failure (and functional decline in class 2 at 24 months postdiagnosis; serum creatinine with persistence: 2.48 mg/dL vs 1.65 with clearance, geometric means, P = .018). In conclusion, we validate the 2018 Banff Working Group PVN classification that provides significant clinical information and enhances comparative data analysis.
Super-obese patients had prolonged LOS and worse DGF rates. Perioperative mortality was increased 4.6-fold compared to patients with BMI < 50. In a subgroup analysis, super-obese patients who underwent kidney transplantation had significantly worse graft and patient survival compared to underweight, normal weight, and obesity class I, II, and III (BMI 40-50) patients.
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.
