BACKGROUND Cardiovascular events are frequent and vascular endothelial function is abnormal in patients with chronic kidney disease (CKD). We demonstrated endothelial dysfunction with vitamin D deficiency in CKD patients; however the impact of cholecalciferol supplementation on vascular stiffness and vasomotor function, endothelial and bone biomarkers in(More)
BACKGROUND Equations for estimating glomerular filtration rate (GFR) have not been validated in Sub-Saharan African populations, and data on GFR are few. METHODS GFR by creatinine clearance (Ccr) using 24-hour urine collections and estimated GFR (eGFR) using the four-variable Modification of Diet in Renal Disease (MDRD-4)[creatinine calibrated to isotope(More)
BACKGROUND Human immunodeficiency virus (HIV)-associated nephropathy (HIVAN) is an important cause of end-stage renal disease among African American patients. This study was performed to study the epidemiology of HIVAN in a predominantly black African population and the impact of highly active antiretroviral therapy and other factors on the development of(More)
BACKGROUND Elevated pulse pressure (PP) is an indicator of poor outcome in hypertensives in the general population and on haemodialysis. The prognostic value of PP in pre-dialysis patients with chronic kidney disease (CKD) stages 4/5 and its interaction with renin-angiotensin system (RAS) inhibitors is unknown. METHODS This retrospective study of 349(More)
Hutchison and colleagues report a 10-year experience of dialysis patients admitted to intensive care units (ICUs) in the UK excluding Scotland. Their study is the largest published so far and raises issues of interest to both ICU physicians and nephrologists. Overall, the dialysis patients, although sicker on admission and having pre-existing(More)
BACKGROUND Low serum sodium (Na) has been associated with decreased body mass index and increased cardiovascular mortality in haemodialysis (HD) patients. We examined the relationship between serum Na and selected nutritional parameters of protein energy wasting that are not affected from the hydration status in a cohort of HD patients. METHODS Triceps(More)
BACKGROUND Preclinical studies demonstrate renal proximal tubular injury after administration of some intravenous iron preparations but clinical data on renal effects of intravenous iron are sparse. METHODS FIND-CKD was a 56-week, randomized, open-label, multicenter study in which patients with non-dialysis dependent chronic kidney disease (ND-CKD),(More)
BACKGROUND/AIM The effect of hypertension on mortality in haemodialysis patients is controversial and can be confounded by non-traditional risk factors like systemic inflammation. This study examined the effect of systolic blood pressure (SBP), diastolic blood pressure (DBP), and pulse pressure (PP) on mortality in haemodialysis patients, separately with(More)
A 67-year-old man presented to the Accident and Emergency department in September 2004 with cough and sudden shortness of breath. In 2002, he had suffered a left occipital infarct that presented as a transient ischaemic attack. In 2003, he sustained bilateral cerebellar infarcts that left him with residual tremor and ataxia (Figure 1). He took regular(More)
