Hypercholesterolemia-induced increase in plasma oxidized LDL abrogated pro angiogenic response in kidney grafts.

Background: Renal transplantation is increasingly associated with the presence of comorbidity factors such as dyslipidemia which could influence the graft outcome. We hypothesized that hypercholesterolemia could affect vascular repair processes and promote post-transplant renal vascular remodeling through the over-expression of the anti-angiogenic thrombospondin-1 interacting with vascular endothelial growth factor-A levels.

Methods: We tested this hypothesis in vitro, in vivo and in a human cohort using (1) endothelial cells; (2) kidney auto-transplanted pig subjected (n = 5) or not (n = 6) to a diet enriched in cholesterol and (3) a renal transplanted patient cohort (16 patients).

Prevalence of Novel Mutations in Antenatal Bartter Syndrome.

Background And Objectives: Mutations in the gene, located on the X chromosome, have been recently detected in males with a transient form of antenatal Bartter syndrome or with idiopathic polyhydramnios. The aim of this study is to analyze the proportion of the population with mutations in this gene in a French cohort of patients with antenatal Bartter syndrome.

Design, Setting, Participants, & Measurements: The French cohort of patients with antenatal Bartter syndrome encompasses 171 families.

Growth deceleration in children treated with imatinib for chronic myeloid leukaemia.

Purpose: The aim is to study statural growth in a large cohort of children with chronic myeloid leukaemia (CML) treated with front-line imatinib.

Methods: Retrospective data from 81 children less than 18 years of age with CML identified in the French pediatric registry were analysed. Height was expressed as standard deviation score (SDS).

Strategies to optimize kidney recovery and preservation in transplantation: specific aspects in pediatric transplantation.

In renal transplantation, live donor kidney grafts are associated with optimum success rates due to the shorter period of ischemia during the surgical procedure. The current shortage of donor organs for adult patients has caused a shift towards deceased donors, often with co-morbidity factors, whose organs are more sensitive to ischemia-reperfusion injury, which is unavoidable during transplantation. Donor management is pivotal to kidney graft survival through the control of the ischemia-reperfusion sequence, which is known to stimulate numerous deleterious or regenerative pathways.
