Improved cognitive function after kidney transplantation compared to hemodialysis.

End-stage renal disease is associated with chronic stress that in turn may result in endocrine changes, affect cognitive, and physical capacities and increase the risk for cardiovascular events. The objective of this study was to evaluate and characterize possible stress parameters and compare cognitive function in those patients. Physiological and biochemical stress parameters as well as cognitive function were assessed in 17 hemodialysis and 18 renal transplant patients and both groups were compared.

Functional Assessment of Fatigue and Other Patient-Reported Outcomes in Patients Enrolled in the Global aHUS Registry.

Introduction: Atypical hemolytic uremic syndrome (aHUS) is a progressive and potentially life-threatening disease characterized by complement-mediated thrombotic microangiopathy. Patients with aHUS may experience fatigue, which can negatively impact their lives, but there is a knowledge gap regarding disease burden in these patients.

Methods: In this longitudinal study, patients with aHUS from the Global aHUS Registry who completed patient-reported outcome assessments (Functional Assessment of Chronic Illness Therapy-Fatigue scale [FACIT-Fatigue], general health status, and work status) at ≥2 time points were assessed relative to treatment status: (i) never treated with eculizumab; (ii) on eculizumab at registry enrollment and continued therapy; and (iii) started eculizumab after registry enrollment.

Self-management in adrenal insufficiency - towards a better understanding.

Patients with adrenal insufficiency (AI) require life-long glucocorticoid (GC) replacement treatment and dose adjustment in stress situations to prevent life-threatening adrenal crises. Herein this study we evaluated the patients' healthcare situation and their knowledge on AI, comparing various aspects to a prior survey in 209 physicians. Using a questionnaire, we conducted a comprehensive survey among 33 AI patients who were treated at the endocrine outpatient clinics of two University Hospitals in Germany.

Beating the odds--surviving extreme hyperkalemia.

Severe hyperkalemia (>7 mmol/L) is a medical emergency because of possible fatal arrhythmias. We here report the case of a 58-year-old woman surviving extreme hyperkalemia (>10 mmol/L). The patient with a history of congestive heart failure, a DDD pacemaker and mild chronic renal insufficiency was admitted with progressive weakness and sudden onset of hypotension and bradycardia in the absence of any pacemaker action.

No aggravation of renal injury in apolipoprotein E knockout mice (ApoE(-/-)) after subtotal nephrectomy.

Background: There is substantial experimental evidence that various forms of dyslipidaemia aggravate the course of renal failure and that reversal of dyslipidaemia ameliorates progression of renal failure. The apolipoprotein E knockout mouse (ApoE(-/-)) is an established model of accelerated atherogenesis. We investigated whether the course of renal disease after uninephrectomy (UNX) and subtotal nephrectomy (SNX) is altered in ApoE(-/-) mice compared with their genetic controls.

Cardiomyocyte loss in experimental renal failure: prevention by ramipril.

Background: The development of left ventricular hypertrophy (LVH) and of structural abnormalities of the heart is a key abnormality in renal failure that potentially contributes to the high rate of cardiac death. In renal failure, the behavior of cardiomyocyte volume and number in the development of LVH has so far not been investigated. A potential role of the (local) renin-angiotensin system (RAS) in the genesis of LVH has been suspected.
