Serum albumin, body weight and inflammatory parameters in chronic hemodialysis patients: A three-year longitudinal study

Backgrounds and Aims: The present study aimed at making prospective longitudinal measurements of nutritional and inflammatory parameters to determine whether nutritional and inflammatory status decline or increase over time in a cohort of prevalent hemodialysis patients, and to evaluate which factors influence eventual changes. Patients: 64 hemodialysis patients were followed at 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, and 36 months. At each follow-up visit, dry body weight, serum albumin, serum total cholesterol, total white blood cells, total lymphocyte count, serum glucose, C-reactive protein, ferritin, fibrinogen, hemoglobin, and weekly erythropoietin dose were assessed. Main Outcome Measures: Changes in nutritional and inflammatory parameters over time. Results: 43 patients completed the study at 36 months. Mean serum albumin levels (g/dl) improved significantly between baseline (3.76 ± 0.24) and 36 months (3.93 ± 0.27) (F = 4.005; p = 0.0009). Dialytic age was significantly associated with changes of serum albumin (F = 2.797; p = 0.028). The mean dry weight slightly remained stable over time (F = 1.473; p = 1.0) as well as the level of total cholesterol (p = 0.77) and lymphocyte count (F = 1.539; p = 0.186). Over time, the levels of C-reactive protein tended to decrease, although the differences were not statistically significant (F = 1.332; p = 0.19). Over time, the serum level of fibrinogen (F = 0.422; p = 0.17) and ferritin (F = 0.314; p = 0.52) remained stable. The number of white blood cells significantly decreased over time (F = 4.691; p = 0.0079) and dialytic age (F = 3.214; p = 0.015) was the variable significantly associated with such decline. The hemoglobin levels (F = 1.423; p = 0.14) and the weekly erythropoietin dose did not change significantly during the study (F = 1.019; p = 0.61), nor did the serum glucose levels (F = 1.231; p = 0.10). Conclusion: These results support the hypothesis that end-stage renal disease and HD are not necessarily associated with deterioration of the nutritional status over time. Copyright © 2007 S.

Malnutrition in hemodialysis patients: What therapy?

Malnutrition is common in hemodialysis patients and is a powerful predictor of morbidity and mortality. Although much progress has been made in recent years in identifying the causes and pathogenesis of malnutrition in hemodialysis patients, as well as recognizing the link between malnutrition and morbidity and mortality, no consensus has been reached concerning its management. Along with such conventional interventions as nutritional counseling, oral nutritional supplements, and intradialytic parenteral nutrition, novel preventive and therapeutic strategies have been tested, such as appetite stimulants, growth hormone, androgenic anabolic steroids, and anti-inflammatory drugs, with contradictory and nonconclusive results. Malnutrition still remains a great challenge for nephrologists in the third millennium

Interventions to counteract anorexia in dialysis patients

The treatment of anorexia in chronic hemodialysis patients is based on a therapeutic strategy which includes optimal dialysis dose (through daily or nocturnal dialysis), support of food intake (through nutritional counseling and oral nutritional supplements), counteractive action to anorexic agents (e.g., inflammatory cytokines and low levels of branched chain amino acids), stimulation of appetite (ghrelin), and attention to associated symptoms (e.g., symptoms of depression and anxiety, fatigue, other comorbidities). However, the fact remains that the studies so far conducted are insufficient both in terms of number and quality to provide guidelines for clinical and research purposes. Randomized, controlled trials are needed in the future to define the best strategy to counteract anorexia in maintenance dialysis patients

Circulating Bacterial-Derived DNA Fragments and Markers of Inflammation in Chronic Hemodialysis Patients

Background and objectives: Bacterial-derived DNA fragments (BDNAs) have been shown to be present in dialysis fluid, to pass through dialyzer membranes, and to induce IL-6 (IL-6) in mononuclear cells. The present study aimed at assessing the eventual presence of BDNAs in the blood of hemodialysis (HD) patients and if this is associated with markers of chronic inflammation

Self-reported physical activity in patients on chronic hemodialysis: correlates and barriers

The knowledge of the barriers that are associated with decreased physical activity (PA) in patients on chronic hemodialysis (PCH) may be of primary importance for the nephrologists. Thus, we aimed to assess the barriers associated with the absent or reduced PA in PCH of a Mediterranean country

Fatigue Is Associated With Serum Interleukin-6 Levels and Symptoms of Depression in Patients on Chronic Hemodialysis

Little is known about activated immune-inflammatory pathways and interleukin-6 (IL-6) in the development of fatigue and/or depression in patients with end-stage renal disease on chronic hemodialysis (HD)

PARATHYROID CARCINOMA IN A CHRONIC HEMODIALYSIS PATIENT: CASE REPORT AND REVIEW OF THE LITERATURE

Parathyroid carcinoma is a rare disease in normal population as well as in patients with end-stage renal disease. Approximately 700 cases have been reported and, of these, 20 occurred in patients receiving chronic hemodialysis. We describe a case of parathyroid carcinoma in a 59-year-old female patient with end-stage renal disease secondary to membranous glomerulonephritis treated by hemodialysis since 1995. In September 1998, the calcium level was 12.4 mg/dl and intact parathyroid hormone serum levels were 1366 pg/ml (normal range, 25-65). A routine ultrasonographic examination of the neck revealed enlargement of two parathyroid glands, the left inferior gland being the largest and measuring 2x3x2 cm. In October 1998, resection of two parathyroid glands was performed. On the basis of histology, which documented the presence of proliferating cells arranged in sheets or in a trabecular pattern, numerous mitosis and vascular invasion, a diagnosis of parathyroid carcinoma was made

Mortality in hospitalized chronic kidney disease patients starting unplanned urgent haemodialysis

Data on the outcome of chronic kidney disease (CKD) patients who are hospitalized and start unplanned urgent haemodialysis (HD) are lacking. This prospective, longitudinal, observational study aimed to define the hospital mortality rate and associated factors in CKD patients who start unplanned urgent HD
