Vascular access thrombosis (VAT) is a major cause of morbidity in chronic hemodialysis (HD) patients and is characterized by chronic inflammation. Pulse pressure (PP) is positively associated with chronic inflammation. Whether patients with high PP are at a higher risk for VAT, however, remains unknown. We retrospectively reviewed chronic HD ...

Background/Aims: End-stage renal disease (ESRD) patients have an increased risk of atherosclerotic complications. In both hemodialysis (HD) patients and the general population, it has become evident that inflammation plays an important role in the pathogenesis of atherosclerotic complications. Oral and dental problems in ESRD patients could be an important source ...

BACKGROUND: The enteric ganglions and the outflow tract of the heart originate from the neural crest. Impaired migration or differentiation of the neural crest cells causes Hirschsprung's disease (HD) and results in the development of cardiac outflow tract malformations. We hypothesize that the incidence of HD and bowel disorders associated ...

OBJECTIVES: Metformin-associated lactic acidosis is a rare and serious complication of biguanide treatment. It usually occurs when a precipitating disease induces an acute renal failure and an incidental overdose. Voluntary intoxication is rare. Bicarbonate hemodialysis (HD) is recommended to decrease metformin levels and correct acidosis but its optimal duration has ...

Hyperkalemia is exacerbated by angiotensin converting enzyme inhibitors (ACE-I). Distal potassium (K(+)) secretion is negligible in anuric patients. ACE-I therapy may reduce renal, peritoneal, and colonic K(+) losses. We examined the effect of ACE-I therapy on serum, urinary, and dialysate K(+) in a cross-section of peritoneal and hemodialysis patients. Serum, ...

BACKGROUND: Multiple lines of evidence have indicated that the dose of hemodialysis (HD) affects patient outcome. According to K-DOQI, daily spKt/V > 1.2 predicts the morbidity and mortality among thrice-weekly HD. However in developing countries, about three-fourths of end stage renal disease patients undergo twice-weekly HD. No data studied the ...

BACKGROUND: Skin hyperpigmentation in end-stage renal disease (ESRD) patients has been attributed to the accumulation of middle-molecular-weight (MMW) substances. Although an MMW mechanism suggests that hyperpigmentation may be improved by high-flux haemodialysis (HF-HD) and haemodiafiltration (HDF), this possibility has not been explored. In the present study, we investigated the impact ...

BACKGROUND: Haemodialysis (HD) and peritoneal dialysis (PD) should be regarded as complementary methods of renal replacement therapy. Approximately 10-20% of patients on PD are transferred annually to HD due to technique failure. Much smaller proportion of patients changes modality from HD to PD, predominantly due to vascular access problems, cardiac ...

BACKGROUND: Intradialytic morbid events (IMEs) during haemodialysis (HD), including symptomatic hypotension, are related to ultrafiltration (UF)-induced hypovolaemia. Blood volume monitoring and automatic feedback control of the UF rate were developed to limit the extent of hypovolaemia during dialysis. The present study investigated the effect of blood volume (BV)-controlled UF on ...

BACKGROUND: Serious hyperkalemia was reported in 10% of chronic hemodialysis (HD) patients that could lead to arrhythmia and death. Angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin II receptor blockers (ARB) are well accepted for cardio-protective benefits. The relationship between renin-angiotensin system blockade (RASB) and hyperkalemia in chronic HD patients remains controversial. ...

BACKGROUND: Hyperphosphatemia provides relevant and dangerous evidence of end-stage renal disease (ESRD) in patients undergoing periodic hemodialysis. The relationship between hyperphosphatemia and cardiovascular calcification, with the consequences of high morbidity and mortality after cardiovascular events, is well-defined. Hyperphosphatemia is treated by dietary limitation of phosphorus ingestion and by phosphate binders, ...

BACKGROUND: Measuring arterial stiffness (augmentation index (AI), aortic pulse wave velocity (PWV)) in hemodialysis (HD) patients has prognostic significance. To assess its validity, the new oscillometric Arteriograph device (AI(A), PWV(A)) was compared to the validated PulsePen tonometer (AI(P), PWV(P)). METHODS: AI and PWV were measured in 98 patients with both ...
