Cardiorenal Protection in Diabetic Kidney Disease.

Over the last 5 years there have been many new developments in the management of diabetic kidney disease. Glucagon-like peptide-1 receptor agonists (GLP-1 RA) and sodium-glucose cotransporter-2 (SGLT2) inhibitors were initially used for glycemic control, but more recent studies have now shown that their benefits extend to cardiovascular and kidney outcomes. The recent addition of data on the novel mineralocorticoid receptor antagonist (MRA) gives us another approach to further decrease the residual risk of diabetic kidney disease progression. In this review we describe the mechanism of action, key studies, and possible adverse effects related to these three classes of medications. The management of type 2 diabetes now includes an increasing number of medications for the management of comorbidities in a patient population at significant risk of cardiovascular disease and progression of chronic kidney disease. It is from this perspective that we seek to outline the rationale for the sequential and/or combined use of SGLT2 inhibitors, GLP-1 RA and MRAs in patients with type 2 diabetes for heart and kidney protection.

Posttransplant Lymphoproliferative Disorders in Irish Renal Transplant Recipients: Insights From a National Observational Study.

BACKGROUND: Posttransplant lymphoproliferative disorders (PTLD) are a common malignancy after renal transplantation with a high incidence of PTLD described in the first posttransplant year. We sought to determine incidence and risk determinants of PTLD in Irish kidney transplant recipients. METHODS: Retrospective observational study of 1996 adult first kidney transplant recipients between 1991 and 2010 in the Republic of Ireland. Recipients were cross-referenced with the National Cancer Registry to determine incidence of PTLD. Kaplan-Meier analysis was performed for PTLD-free survival, allograft survival, and patient survival after PTLD. Cox proportional hazards models were used to identify independent risk factors for PTLD in our population. RESULTS: We identified 31 cases of PTLD during the study period. Histological subgroups included: early lesions (n = 1); polymorphic PTLD (n = 1); monomorphic PTLD (n = 27), Hodgkin disease (n = 2). Median time to PTLD diagnosis was 8.3 (range, 1.2-13.9) years. Cumulative incidence (95% CI) of PTLD at 1, 2, 3, 5, 10, and 15 years was 0%, 0.16% (0.05-0.5%), 0.21% (0.08-0.57%), 0.21% (0.08-0.57%), 1.76% (1.15-2.69%), and 3.07% (2.1-4.43%), respectively. Allograft survival after PTLD diagnosis was 94.4% (66.6-99.2%) at 5 years. Patient survival after PTLD diagnosis was 64% at 1 year, 53% at 2 years, 48% at 5 years, and 37% at 10 years. No risk factors for PTLD were identified. CONCLUSIONS: We found a paucity of early onset PTLD in our cohort with no cases in the first posttransplant year. Potential contributing factors included a high prevalence of previous Epstein-Barr virus exposure and a relatively low immunological risk profile in our recipient cohort compared with prior studies. Further studies are required to reevaluate the epidemiology of PTLD in the modern era of transplant immunosuppression.

Treatment of preeclampsia: current approach and future perspectives.

Hypertension is the most common medical disorder encountered during pregnancy, occurring in about 6-8 % of pregnancies. Preeclampsia is a pregnancy-specific disorder that occurs after 20 weeks' gestation, characterized by hypertension and proteinuria. Preeclampsia can also occur superimposed upon chronic hypertension. Eclampsia is the convulsive form of preeclampsia, and affects 0.1 % of all pregnancies. In low-income and middle-income countries, preeclampsia and eclampsia are associated with 10-15 % of direct maternal deaths. Women who develop preeclampsia in pregnancy are at greater risk of cardiovascular and cerebrovascular events even years after their pregnancies. There is significant progress in the elucidation of the underlying mechanisms and pathophysiology of preeclampsia, although its therapeutics remains challenging; delivery of the fetus is still the definitive treatment. Different international societies have produced recommendations and guidelines for clinicians treating preeclampsia, with an overall goal of improving maternal and fetal outcomes. In this review, we focus on the level of blood pressure at which to commence treatment and the current clinical management strategies available to treat and possibly prevent preeclampsia. We also briefly outline some newer perspectives on management of the disorder.
