Background. Kidney function declines with age, but a substantial portion of this decline has been attributed to the higher prevalence of risk factors for kidney disease at older ages. The effect of age on kidney function has not been well described in a healthy population across a wide age spectrum.Methods. The authors pooled individual-level cross-sectional data from 18 253 persons aged 28-100 years in four studies: the Cardiovascular Health Study; the Health, Aging and Body Composition Study; the Multi-Ethnic Study of Atherosclerosis and the Prevention of Renal and Vascular End-Stage Disease cohort. Kidney function was measured by cystatin C. Clinical risk factors for kidney disease included diabetes, hypertension, obesity, smoking, coronary heart disease, cerebrovascular disease, peripheral arterial disease and heart failure.Results. Across the age range, there was a strong, non-linear association of age with cystatin C concentration. This association was substantial, even among participants free of clinical risk factors for kidney disease; mean cystatin C levels were 46 higher in participants 80 and older compared with those <40 years (1.06 versus 0.72 mgL, P < 0.001). Participants with one or more risk factors had higher cystatin C concentrations for a given age, and the age association was slightly stronger (P < 0.001 for age and risk factor interaction).Conclusions. There is a strong, non-linear association of age with kidney function, even in healthy individuals. An important area for research will be to investigate the mechanisms that lead to deterioration of kidney function in apparently healthy persons.

Background: Postgraduate training is aimed at equipping the trainee with the necessary skills to practise as an expert. Non-nephrology specialist physicians render the bulk of pre-end-stage renal disease care for patients with chronic kidney disease (CKD). We sought to ascertain the knowledge of CKD amongst non-nephrology specialist physicians who serve as trainers and examiners for a training, accrediting and certifying body in postgraduate medicine in West Africa. We also compared the knowledge of family physicians and non-nephrology internists. Methods: Self-administered questionnaires were distributed to non-nephrology specialist physicians who serve as examiners for the West African College of Physicians. Results: Only 19 (27.5%) of the respondents were aware of the Kidney Disease Outcomes Quality Initiatives guidelines for CKD management. Twenty five (36.2%) of the respondents had adequate knowledge of CKD. There was no significant difference in the proportion of family physicians and non-nephrology internists who had adequate knowledge of CKD (27.3% vs. 40.4% respectively; p = 0.28). Hypertension and diabetes mellitus were identified by all of the physicians as risk factors for CKD. Non-nephrology internists more frequently identified systemic lupus erythematosus as a risk factor for CKD, urinalysis with microscopy as a laboratory test for CKD evaluation, and bone disease as a complication of CKD than family physicians. Conclusion: There is a lack of adequate CKD knowledge amongst non-nephrology specialist physicians, since many of them are unaware of the CKD management guidelines. Educational efforts are needed to improve the knowledge of CKD amongst non-nephrology specialist physicians. Guidelines on CKD need to be widely disseminated amongst these physicians. © 2012.

Background: Patients with chronic kidney disease (CKD) not requiring dialysis have a high prevalence of 25-hydroxyvitamin D (25(OH)D) deficiency but the relationship between 25(OH)D levels and metabolic syndrome is unknown in this population. Methods: This study analyzed stored plasma samples from 495 non-diabetic subjects with severe kidney disease, not yet on dialysis, who participated in the homocysteine in kidney and end stage renal disease study. Metabolic syndrome was defined as the presence of all three of the following: (1) Serum triglycerides ≥ 150 mg/dl or drug treatment for hypertriglyceridemia; (2) serum high density lipoprotein-cholesterol (HDL-C) < 50 mg/dl for women or < 40 mg/dl for men or drug treatment for dyslipidemia; and (3) blood pressure ≥ 130/85 mmHg or drug treatment for hypertension. Multivariate logistic regression models were used to evaluate the cross-sectional association between plasma 25(OH)D levels and metabolic syndrome. Results: The prevalence of metabolic syndrome increased as 25(OH)D levels declined, with the highest prevalence in participants with 25(OH)D levels < 20 ng/ ml. Participants with 25(OH)D levels < 20 ng/ml had a significantly increased risk of metabolic syndrome compared to subjects with levels > 30 ng/ml after adjustment for multiple confounders (OR 2.25, 95% CI 1.25 - 4.07). Plasma 25(OH)D levels were inversely associated with diastolic blood pressure (R = -0.10, p = 0.029) and serum triglyceride levels (R = -0.14, p = 0.002). Conclusion: 25(OH)D deficiency is strongly associated with an increased risk of metabolic syndrome in non-diabetic patients with severe CKD not yet on dialysis, independent of cardiometabolic risk factors and other important regulators of mineral metabolism. © 2012 Dustri-Verlag Dr. K.

Vesicoureteral reflux (VUR) is a common pediatric anomaly linked to renal scarring and hypertension. Although there are many mouse VUR models, cystograms have previously only been performed in euthanized animals, thus preventing serial assessments for VUR in the same animal and not delineating "live" physiology. Our purpose was to develop a live murine cystogram assay that could be used serially to track reflux. We injected microbubbles via transurethral catheters into bladders of C57BL6/J and C3H/HeJ inbred mouse strains that are known to have low and high VUR rates, respectively. We performed ultrasound to visualize microbubbles in the renal pelvis to determine feasibility of the procedure. We then repeated the microbubble ultrasound using a transducer allowing for visualization of both kidneys and ureters simultaneously and for 3 dimensional (3D) reconstruction. We then performed "euthanized" cystograms on all mice for comparison. C3H/HeJ mice had a strong and persistent microbubble signal in the renal pelvis and ureters bilaterally with low-contrast infusion volumes (<100 μ1) and similarly showed bilateral reflux by euthanized cystograms. With larger infused volumes (≥150 μl), C57BL6/J mice had small volumes of microbubbles in the renal pelvis that cleared quickly and did not show reflux on euthanized cystograms. Thus, using animal models of known VUR, we demonstrate the utility of contrastenhanced ultrasound to visualize reflux in live mice. © 2011 the American Physiological Society.

Background: Children receiving maintenance dialysis exhibit high cardiovascular (CV) associated mortality. We and others have shown high prevalence of cardiac calcifications (CC) in children with endstage renal disease (ESRD). However, no pediatric study has examined modality difference in CC prevalence. The current study was conducted to assess for a difference in CC prevalence between hemodialysis (HD) and peritoneal dialysis (PD) in children with ESRD. Methods: 38 patients (19 female, 19 male; mean age 15.5 ± 4.1 years) receiving dialysis (21 HD, 17 PD) were included in the study. CC were assessed by ultrafast gated CT and quantified by Agatston score. Patients received thrice weekly HD for 3-3.5 hours or daily continuous cycler PD (CCPD). FGF 23, IL-6, IL-8, and CRP levels were obtained at time of CT. Time-averaged (6 months prior to CT) serum Ca, P, Alb, iPTH, and cholesterol levels were obtained. Patients on aspirin, with evidence of infection, underlying collagen vascular disease were excluded. Results: CC were present in 11/38 patients, but more prevalent in HD vs. PD (9/21 vs. 2/17, p = 0.04). Subjects with CC were older (p = 0.0003), had longer dialysis vintage (p = 0.02) and higher serum phosphorus (p = 0.02) and FGF 23 levels (p = 0.03). HD patients also had significantly higher phosphorus (p = 0.02), FGF 23 (p = 0.009), and IL-8 levels (p = 0.02) when compared to PD patients. Residual renal function was not different between modalities or patients with CC. On a multinomial regression model, modality, and age remained independent associations for CC prevalence. Conclusion: We have shown that pediatric patients receiving CCPD have lower CC prevalence conferring lower CV risk. The better control of mineral imbalance in patients receiving PD may play an important role in lower CC prevalence. © 2014 Dustri-Verlag Dr. K. Feistle.
