PURPOSE To assess the effect of hemodialysis on retinal and choroidal thicknesses using spectral-domain optical coherence tomography (SD-OCT). METHODS In this prospective interventional study, 25 hemodialysis patients (17 male, 8 female) were enrolled. All participants underwent high-speed, high-resolution SD-OCT (λ=840 mm; 26.000 A-scans/s; 5 µm resolution) before and after hemodialysis. Cho...

OBJECTIVE To evaluate the ability of different parameters of exercise treadmill test to detect autonomic dysfunction in hemodialysis patients. METHODS Cross-sectional study involving hemodialysis patients and a control group. Clinical examination, blood sampling, echocardiogram, 24-hour Holter, and exercise treadmill test were performed. A ramp treadmill protocol symptom-limited with active r...

Objectives: The purpose of this study was to assess how the preload reduction a#ects left ventricular LV diastolic function in hemodialysis patients with LV hypertrophy. Methods: Subjects included 14 patients with LV hypertrophy receiving hemodialysis. The subjects underwent echocardiographic and pulsed Doppler examinations before and after hemodialysis, and the data were analyzed to determine ...

Infection is a common complication and is the second leading cause of death in hemodialysis patients. The risk of bacteremia in hemodialysis patients is 26-fold higher than in the general population, and 1/2-3/4 of the causative organisms of bacteremia in hemodialysis patients are Gram-positive bacteria. The ratio of resistant bacteria in hemodialysis patients compared to the general population...

OBJECTIVE To evaluate pulmonary function and respiratory muscle strength in chronic renal failure patients, correlating these variables with hemodialysis-related weight fluctuation; to study the correlation between the duration hemodialysis and potential respiratory alterations. METHODS Seventeen patients (median age, 47 years; interquartile range, 41-52 years), submitted to three weekly hemo...

Klebsiella pneumoniae bacteremia associated with a Tesio hemodialysis catheter To the Editor: Catheter-associated bacteremia is a serious complication of temporary hemodialysis vascular access. Bacteremia is the second leading cause of death in hemodialysis patients. Infectious episodes are also the leading cause for untimely catheter removal and for morbidity in dialysis patients. In a study o...

BACKGROUND The relationship between intraocular pressure (IOP) changes and hemodialysis has been evaluated for several decades. However, no report on an IOP rise in uveitis patients during hemodialysis has been previously documented. This report describes the case of an uveitis patient with repetitive IOP spikes associated with severe ocular pain during hemodialysis sessions, which resolved aft...

Frequent hemodialysis improves cardiovascular surrogates and quality-of-life indicators, but its effect on survival remains unclear. We used a matched-cohort design to assess relative mortality in daily home hemodialysis and thrice-weekly in-center hemodialysis patients between 2005 and 2008. We matched 1873 home hemodialysis patients with 9365 in-center patients (i.e., 1:5 ratio) selected from...

INTRODUCTION Patients undergoing hemodialysis require direct and continuous care. Identifying the barriers to and factors facilitating hemodialysis care can improve care quality. OBJECTIVES The aim of this study was to assess the barriers and facilitators of care for hemodialysis patients. PATIENTS AND METHODS This study was conducted as a qualitative study and it utilized content analysis ...
