We will present our experience and our preliminary data about the correlation between cardiac calcification and QT interval (and QT dispersion) in uraemia. We studied 32 haemodialysis (HD) patients (age 69 +/- 16 years, time on dialysis 32 +/- 27 months) and 12 chronic kidney disease stage 4 (CKD-4) patients ...

Heparin-induced thrombocytopenia (HIT) is a syndrome caused by platelet-activating antibodies that recognize complexes of platelet factor 4 (PF4) and heparin. Thrombocytopenia is the most common clinical feature of HIT. HIT can be considered as a hypercoagulable state, with a high risk of thrombosis. Another feature of HIT is an acute ...

AIMS: The two main renal replacement therapies (RRT)--hemodialysis (HD) and peritoneal dialysis (PD)--have been considered to be antagonistic in most published studies on the clinical outcomes of dialysis patients. Recently, it has been suggested that the complementary use of both modalities as an integrated care (IC) strategy might improve the ...

BACKGROUND: The treatment of deranged water homeostasis of hemodialysis (HD) patients needs focusing on an accurate assessment of dry weight (DW). However, the correct estimation of post-dialysis DW is still a problem. Echocardiography of inferior caval vein diameter (ICVD) was recently considered as a reliable technique to estimate DWs of ...

An increase of brain natriuretic peptide (BNP) levels is commonly observed in patients on dialysis. Increased circulating levels of BNP are related to future cardiac events and associated with shorter survival in patients on chronic hemodialysis (HD). During the first 1 or 2 years on dialysis, patients on peritoneal dialysis ...

OBJECTIVE AND BACKGROUND: Previous studies have shown that patients with frontal-striatal dysfunction demonstrate improved performance on tests of recognition memory relative to free recall memory, suggesting deficits in retrieval processes. Not all studies, however, have indicated that all patients with frontal-striatal dysfunction display this profile. In this study, we examined ...

Huntington's disease (HD) is caused by an expanded CAG mutation and may show a heterogeneous clinical presentation. To date, although the age at onset mostly depends on the expanded CAG repeat number, no validated easy-to-test biomarkers exist either for following up patients progression rate or for exactly predicting age at ...

BACKGROUND: Increased vascular calcification plays an important role in the pathogenesis of cardiovascular events in chronic kidney disease (CKD) patients. It is the result of an active ossification process counteracted by 'protective' proteins, such as matrix GLA protein (MGP). Polymorphisms of MGP have been identified. METHODS: The aim of this ...

BACKGROUND: Hyperhomocysteinemia is an independent risk factor of coronary artery heart disease (CAHD) and atherosclerosis in a normal population. However, it is still controversial in end-stage kidney disease patients who underwent long-term dialysis. Carotid intima-media thickness (IMT) is the standard non-invasive measurement of atherosclerosis. The aims of the present study ...

BACKGROUND: Although previous studies reported that the prevalence of Fabry's disease was 0.16 - 1.2% in hemodialysis (HD) patients based on measurement of a-galactosidase A (alpha-Gal A) activity, few reports detected female patients by the screening for alpha-Gal A. Here we determined the prevalence of Fabry's disease not only in ...

Apart from its well-known functions in calcium homeostasis and parathyroid hormone regulation, 1,25-(OH)2D3 and its synthetic analogs are being increasingly recognized for their potent antiproliferative, pro-differentiative and immunomodulating activities. The effects of these drugs are exerted either via vitamin D receptor-dependent genomic, or cell-surface receptor-mediated, non-genomic pathways. Several vitamin D ...

BACKGROUND: Haemodialysis patients (HD) have been characterized by a high incidence and prevalence of atherosclerotic cardiovascular disease. Based on the traditional cardiovascular risk factors in this population, we cannot explain this high incidence and prevalence. One of the mechanisms contributing to cardiovascular risk in HD patients may be to uraemic ...

According to the now classical basal ganglia-thalamocortical circuitry model, the chorea of Huntington's disease (HD) and the hypokinesia in Parkinson's disease (PD) are explained by a decrease in the inhibitory output (reduced firing rates) from the globus pallidus internus (GPi) in HD and increased output in PD. Differences between firing ...

BACKGROUND: We have demonstrated previously that at referral most chronic kidney disease (CKD) patients have suboptimal metabolic and hypertension control. Although several studies suggest that CKD clinics improve patient outcome, in fact there are minimal published data describing the actual effect of such clinics on these parameters. METHODS: We performed ...

Because inflammation influences thyroid function, it was hypothesized that low plasma free triiodothyronine (fT3) in ESRD may be an unsuspected expression of the inflammatory state of these patients. This study investigated (1) the steady-state relationship between fT3 and inflammation markers (IL-6 and C-reactive protein) and markers of endothelial activation (intercellular ...

Management of secondary hyperparathyroidism is challenging with traditional therapy. The calcimimetic cinacalcet HCl acts on the calcium-sensing receptor to increase its sensitivity to calcium, thereby reducing parathyroid hormone (PTH) secretion. This phase 3, multicenter, randomized, placebo-controlled, double-blind study evaluated the efficacy and safety of cinacalcet in hemodialysis (HD) and peritoneal ...

AIMS: Recombinant human erythropoietin (r-HuEPO) is widely used to correct renal anemia in uremic patients. Interestingly, some chronic hemodialysis (HD) patients can maintain high hemoglobin level without the need of r-HuEPO. The aim of this study is to investigate clinical features, iron metabolism and erythropoiesis of these r-HuEPO-independent HD patients. ...
