| Several antibodies, including anticardiolipin antibodies (ACA), have been detected among chronically infected hepatitis C virus (HCV) patients. The present work aimed at ascertaining the clinical significance of ACA levels among HCV infection associated with two commonly encountered diseases, thrombocytopenia and arteriovenous-shunt malfunction. Six groups were studied, 11 HCV-positive thrombocytopenic patients (group I), 14 HCV-positive non-thrombocytopenic patients (group II) and 15 healthy controls (group III), 11 anti-HCV-positive hemodialysis patients with non-functioning shunt (group IV), 14 anti-HCV-positive hemodialysis patients with patent shunt (group V) (Bain Medical Equipment Co., China) and 15 healthy controls (group VI). Anticardiolipin... |

| ABSTRACTIn coinfected HBV/HCV patients, HBV replication is usually suppressed by HCV over the time. No study to date has evaluated the HBV viremia in long-term follow-up after HCV treatment in hemodialysis patients with HBV/HCV coinfection. This study aimed to assess the evolution of HBV viremia after HCV treatment in this special population. Ten hemodialysis patients with HBV/HCV coinfection with dominant HCV infection (HBV lower than 2000 IU/mL) and significant fibrosis were treated with interferon-alpha 3 MU 3×/week for 12 months and could be followed for at least 36 months after HCV treatment. Six cases of HBV reactivation (60%) during follow-up were observed and 5/6 had been successfully treated for HCV. Patients with HBV reactivation received... |

| The vancomycin dose for hemodialysis (HD) patients should be adjusted by monitoring drug serum concentrations. However, this procedure is not available in most health services in Brazil, which usually adopts protocols based on published studies. The trials available are controversial, and several have not been conducted with current dialyzers. This study aimed at assessing the suitability of vancomycin serum concentrations in HD patients at a public hospital. Blood samples of HD patients were collected from November 2006 to May 2007, at time intervals of 48, 96, 120, or 168 hours after vancomycin administration. Drug measurement was performed with polarized light immunofluorescence. Approximately 86% of trough vancomycin serum concentrations were below the... |

| INTRODUCTION: Renal replacement therapy is the treatment of end-stage chronic kidney disease and can be performed through dialysis catheters, arteriovenous fistulas/grafts, and peritoneal dialysis. Patients are usually immunocompromised and exposed to invasive procedures, leading to high rates of infection and increased mortality.OBJECTIVES: To compare the prevalence of infection and related deaths, as well as the sensitivity profile of the putative bacteria in patients treated with peritoneal dialysis, arteriovenous fistula hemodialysis and catheter hemodialysis.METHODS: This is case-control study. Six hundred forty-four patients undergoing renal replacement therapy were selected. Patients were divided into three groups according to the modality of... |

| BACKGROUND: Hepatitis C virus (HCV) infection is the most common cause of acute or chronic hepatitis in patients on hemodialysis (HD). The purpose of this study was to describe the prevalence of positive HCV RNA and investigate injection drug use as an emerging risk factor in patients with chronic renal disease on HD. METHODS: This was a multicenter cross-sectional study with 325 patients with chronic renal disease on HD in the period between August 1, 2005 to August 30, 2006, receiving care at four institutions in the city of Porto Alegre, Southern Brazil. Epidemiological data were collected by means of a structured questionnaire. The following laboratory tests were performed: alanine aminotransferase (ALT), anti-hepatitis C virus antibodies (anti-HCV),... |

| Atherosclerosis is a major complication of chronic renal failure. Microinflammation is involved in atherogenesis and is associated with uremia and dialysis. The role of dialysate water contamination in inducing inflammation has been debated. Our aim was to study inflammatory markers in patients on chronic dialysis, before and 3 to 6 months after switching the water purification system from deionization to reverse osmosis. Patients had demographic, clinical and nutritional information collected and blood drawn for determination of albumin, ferritin, C-reactive protein (CRP), interleukin-6, and tumor necrosis factor-alpha in both situations. Acceptable levels of water purity were less than 200 colony-forming units of bacteria and less than 1 ng/ml of... |

| Hepatitis C (HCV) is not an uncommon feature in hemodialysis (HD) patients and may be a cause of systemic inflammation. Plasma cytokine interleukin-6 (IL-6) is mainly produced by circulating and peripheral cells and induces the hepatic synthesis of C-reactive protein (CRP), which is the main acute phase reactant. The aim of this study was to investigate the influence of HCV on two markers of systemic inflammation, serum CRP and IL-6, in HD patients. The study included 118 HD patients (47% males, age 47 ± 13 years, 9% diabetics) who had been treated by standard HD for at least 6 months. The patients were divided into two groups depending on the presence (HCV+) or absence (HCV-) of serum antibodies against HCV. Serum albumin (S-Alb), plasma high sensitivity... |

| Details about the acid-base changes in hemodialysis are scarce in the literature but are potentially relevant to adequate management of patients. We addressed the acid-base kinetics during hemodialysis and throughout the interdialytic period in a cross-sectional study of adults undergoing conventional hemodialysis. Samples for blood gas analysis were obtained from the arterial limb of the arteriovenous fistula before the first session of the week (HD1), immediately at the end of HD1, and on sequential collections at 15, 30, 45, 60, and 120 min post-HD1. Additional blood samples were collected after ∼20 h following the end of the first dialysis and immediately prior to the initiation of the second dialysis of the week. Thirty adult patients were analyzed... |

| Urinary biomarkers can predict the progression of chronic kidney disease (CKD). In this study, kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), and N-acetyl-β-D-glucosaminidase (NAG) were correlated with the stages of CKD, and the association of these biomarkers with CKD progression and adverse outcomes was determined. A total of 250 patients, including 111 on hemodialysis, were studied. Urinary KIM-1, NGAL, and NAG were measured at baseline. Patients not on dialysis at baseline who progressed to a worse CKD stage were compared with those who did not progress. The association of each biomarker and selected covariates with progression to more advanced stages of CKD, end-stage kidney disease, or death was evaluated by... |

| The present study examined the distribution of hepatitis C virus (HCV) genotypes and subtypes in a hemodialysis population in Goiás State, Central Brazil, and evaluated the efficiency of two genotyping methods: line probe assay (LiPA) based on the 5' noncoding region and nucleotide sequencing of the nonstructural 5B (NS5B) region of the genome. A total of 1095 sera were tested for HCV RNA by RT-nested PCR of the 5' noncoding region. The LiPA assay was able to genotype all 131 HCV RNA-positive samples. Genotypes 1 (92.4%) and 3 (7.6%) were found. Subtype 1a (65.7%) was the most prevalent, followed by subtypes 1b (26.7%) and 3a (7.6%). Direct nucleotide sequencing of 340 bp from the NS5B region was performed in 106 samples. The phylogenetic tree showed that... |

| The objective of the present study was to determine the acute effect of hemodialysis on endothelial venous function and oxidative stress. We studied 9 patients with end-stage renal disease (ESRD), 36.8 ± 3.0 years old, arterial pressure 133.8 ± 6.8/80.0 ± 5.0 mmHg, time on dialysis 55.0 ± 16.6 months, immediately before and after a hemodialysis session, and 10 healthy controls matched for age and gender. Endothelial function was assessed by the dorsal hand vein technique using graded local infusion of acetylcholine (endothelium-dependent venodilation, EDV) and sodium nitroprusside (endothelium-independent venodilation). Oxidative stress was evaluated by measuring protein oxidative damage (carbonyls) and antioxidant defense (total radical trapping... |
