PTDM and prediabetes are very common in renal transplantation. Classic metabolic factors like obesity, prediabetes and insulin resistance promote the evolution of PTDM and prediabetes. Patients with normal glucose metabolism rarely develop PTDM. OGTT is necessary to detect PTDM and prediabetes and thus should be included in clinical practice.
One in two recipients with tacrolimus-based immunosuppresion showed prediabetes or NODAT by 1 year posttransplantation when properly investigated. Older age and high pretransplant body mass index and triglyceride/high density lipoprotein-cholesterol ratio were risk factors for prediabetes. These findings may help applying early interventions to prevent the disorder.
Enalaprilat has an antioxidant effect in cultured mesangial cells. This action is not linked to ACE inhibition, but may be related to an inhibition of the PKC system.
Background. New-onset diabetes after transplantation (NODAT) is associated with poorer outcomes in kidney transplantation (KT). Thus, identification of modifiable risk factors may be crucial for ameliorating the impact of this entity on transplant outcomes. We assessed the relationships between the weight, body mass index (BMI) and weight gain with NODAT.Methods. We retrospectively analysed 2168 KT performed in Spain during 1990, 1994, 1998 and 2002, with a functioning graft after the first year. At 1 year after KT, three groups were considered: (i) NODAT group (n = 215); (ii) impaired fasting glucose (IFG) group (n = 389); (iii) control group (n = 1564).Results. The incidence of NODAT was 10.8%, 9.9% and 10.0% at 3, 12 and 24 months post-transplantation, respectively. Older recipient age (P < 0.0001) and greater use of tacrolimus (P < 0.0001) were observed in NODAT group. Obesity was more frequent in NODAT group (P < 0.0001), but patients with NODAT had a lower weight gain during the first year after KT (P = 0.038). On multivariate analysis, independent risk factors associated with the development of NODAT were: recipient age [odds ratio (OR): 1.060, P = 0.0001], tacrolimus (OR: 1.611, P = 0.005), triglycerides (OR: 1.511, P = 0.018), positive hepatitis C virus (HCV) status (OR: 1.969, P = 0.001) and pre-transplant body mass index (BMI) (OR: 1.135, P = 0.0001), but not the weight gain.Conclusions. BMI, but not the weight gain at 1 year after transplant, is an independent risk factor for NODAT. Tailoring clinical strategies may minimize the impact of this complication.
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.
