Although it has been described in adults that renal grafts in the context of CLKT have a lower number of AR episodes and improved renal allograft survival, this has never been examined in pediatrics. We performed a single center retrospective case-control study examining 10 patients aged 10+/-6 yr with a CLKT that survived the post-surgery period of six months, and compared outcomes to a group of 20 KO transplants matched for age, era, and immunosuppression. We observed a significant reduction in the incidence of AR episodes in the CLKT group. To evaluate whether or not this experience was reproducible nationally, we performed an analysis of the 1995-2005 UNOS database. As of March 2007, 111 CLKT and 3798 KO transplants were identified from the OPTN/UNOS data. There was a significant improvement in the late kidney graft survival at five yr post-transplant in the CLKT group. These findings support the concept that liver transplantation is immunologically protective of the kidney allograft in CLKT.

Early clinical and histological recurrence of DDD in the transplanted kidney in this 14-year-old patient was treated for 30 months with eculizumab. The patient remains asymptomatic, has no proteinuria and her kidney function is intact.

Few studies are focused on the antioxidant status and its changes in anorexia nervosa (AN). Based on the hypothesis that renutrition improves that status, the aim was to determine the plasma antioxidant status and the antioxidant enzymes activity at the beginning of a personalized nutritional program (T0) and after recovering normal body mass index (BMI) (T1). The relationship between changes in BMI and biochemical parameters was determined. Nutritional intake, body composition, anthropometric, hematological and biochemical parameters were studied in 25 women with AN (19.20 ± 6.07 years). Plasma antioxidant capacity and antioxidant enzymes activity were measured. Mean time to recover normal weight was 4.1 ± 2.44 months. Energy, macronutrients and micronutrients intake improved. Catalase activity was significantly modified after dietary intake improvement and weight recovery (T0 = 25.04 ± 1.97 vs. T1 = 35.54 ± 2.60μmol/min/mL; p < 0.01). Total antioxidant capacity increased significantly after gaining weight (T0 = 1033.03 ± 34.38 vs. T1 = 1504.61 ± 99.73 μmol/L; p < 0.01). Superoxide dismutase activity decreased (p < 0.05) and glutathione peroxidase did not change. Our results support an association between nutrition improvement and weight gain in patients with AN, followed by an enhancement of antioxidant capacity and catalase antioxidant system.
