BACKGROUND Hypertension and fluid overload (FO) are well-recognized problems in the chronic kidney disease (CKD) population. While the prevalence of hypertension is well documented, little is known about the severity of FO in this population. METHODS A new bioimpedance spectroscopy device (BCM-Body Composition Monitor) was selected that allows(More)
Etanercept is a tumor necrosis factor inhibitor used in the treatment of rheumatoid arthritis and, increasingly, in a range of other diseases. We report a case of necrotizing crescentic glomerulonephritis, associated with a positive antineutrophil cytoplasmic antibody, causing acute renal failure in a woman receiving treatment with etanercept for severe(More)
In a retrospective survey of 92 cadaver renal transplant recipients, cytomegalovirus (CMV) infections were detected in 23 of 34 (68 per cent) patients treated with high doses of steroids but in only 27 of 58 (47 per cent) patients given low doses. Pretransplant blood transfusions were associated with both an improvement in one-year allograft survival-rates(More)
Increased hemodialysis frequency can make fluid overload easier to treat, although most patients are still treated thrice weekly. Chronic fluid overload is associated with left ventricular hypertrophy and elevated serum cardiac biomarkers, recognized as mortality risk factors. Serum cardiac troponin T (cTnT), N-terminal prohormone brain natriuretic peptide(More)
Online hemodiafiltration (HDF) has recently become an alternative to conventional hemodialysis for treatment of end-stage renal disease with superior results. Clinical experience with HDF in unselected populations has not been widely published and a longitudinal study on such a group of patients is presented here.
