BACKGROUND We report on a patient with unilateral elevation of intraocular pressure during hemodialysis. CASE A 60-year-old man with unilateral exfoliative material complained of severe pain in the right eye during hemodialysis. OBSERVATIONS The intraocular pressure (IOP) in the patient's right eye was 56 mm Hg, and increased repeatedly during hemodialysis. The IOP in his left eye remained ...

BACKGROUND Oxidative stress increases in patients with end-stage renal disease and exaggerates the related comorbidities. OBJECTIVE The aim of the study was to evaluate the effects of supplementation with decaffeinated green tea extract (catechins) on hemodialysis-induced reactive oxygen species, atherosclerotic disease risk factors, and proinflammatory cytokines. DESIGN We enrolled 6 healt...

BACKGROUND An increase in left ventricular mass (LVM) is associated with mortality and cardiovascular morbidity in patients with end-stage renal disease. METHODS AND RESULTS The Frequent Hemodialysis Network (FHN) Daily Trial randomized 245 patients to 12 months of 6 times per week daily in-center hemodialysis or conventional hemodialysis; the FHN Nocturnal Trial randomized 87 patients to 12 ...

BACKGROUND The utilization of short-term daily hemodialysis has increased over the last few years, but little is known on its effects on the control of serum phosphate and fibroblast growth factor 23 (FGF23) levels. METHODS We therefore performed a cross-sectional study to compare FGF23 levels as well as other biochemical variables between 24 patients undergoing short daily hemodialysis using...

Cardiac events are the major cause of death in hemodialysis patients. Because of the paucity of randomized clinical trials (RCTs) in hemodialysis patients, most cardiovascular therapies in this population are based on observational studies or results extrapolated from studies that excluded hemodialysis patients. However, associations discovered in observational studies do not prove causality, a...

Background: Uremic pruritus is one of the important problems in patients undergoing hemodialysis. Causing the mechanism of uremic pruritus in hemodialysis patients is complex and multifactorial. Almost 60 percent of hemodialysis patients suffer from uremic pruritus. Oral hydroxyzine is a common treatment for uremic pruritus of this patients. This study aimed to survey effect of hydroxyzine on u...

BACKGROUND Hemodialysis requires reliable recurrent access to the circulation. On a chronic basis, this has been best provided by the use of arteriovenous fistulae and arteriovenous grafts. In recent years, hemodialysis catheters have come to play an increasingly important role in the delivery of hemodialysis. The use of both temporary as well as cuffed hemodialysis catheters has emerged as a s...

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...
