Treatment of chronic hepatitis C in hemodialysis patients
2008
Hepatitis C virus (HCV) infection is especially problematic in patients with end-stage renal disease (ESRD) who are undergoing hemodialysis. Rates of HCV infection are higher among hemodialysis patients than in the general population, and several routes of transmission are thought to stem from the dialysis unit. Management of chronic hepatitis C is also more complicated in hemodialysis patients because of altered pharmacokinetics and a predisposition for drug-related toxicity, particularly ribavirin-induced anemia. Clinical trials of patients with chronic hepatitis C and healthy, functioning kidney grafts are rare because of the inherent dangers of graft rejection. As a result, most studies…
Single Intravenous Dose Kinetics and Accumulation of Atenolol in Patients with Impaired Renal Function and on Hemodialysis
1980
The concentration of atenolol in plasma and urine was determined following an intravenous (i.v.) dose given to 17 hypertensive patients with a glomerular filtration rate (GFR) between 5 and 105 ml/min and in 4 patients on hemodialysis. In patients with normal renal function the mean half life of elimination was calculated to be 6.8 h. This value increased to a mean of 50.1 h in patients with a GFR below 10 ml/min. In patients on hemodialysis the half life of elimination was about 4 h. The elimination rate constants as well as the body and renal clearances of atenolol have a significant correlation with the GFR. Although accumulation of atenolol was observed, especially after multiple oral d…
Use of neural networks for dosage individualisation of erythropoietin in patients with secondary anemia to chronic renal failure.
2003
The external administration of recombinant human erythropoietin is the chosen treatment for those patients with secondary anemia due to chronic renal failure undergoing periodic hemodialysis. The goal is to carry out an individualised prediction of the erythropoietin dosage to be administered. It is justified because of the high cost of this medication, its secondary effects and the phenomenon of potential resistance which some individuals suffer. One hundred and ten patients were included in this study and several factors were collected in order to develop the neural models. Since the results obtained were excellent, an easy-to-use decision-aid computer application was implemented.
INT-009 Pharmacokinetics of linezolid and meropenem in intensive care unit patients receiving continuous renal replacement therapy
2016
Background Intensive care unit (ICU) patients often suffer from infections and acute renal failure and might need continuous renal replacement therapy commonly applied by veno-venous hemodialysis (CVVHD) or hemodiafiltration (CVVHDF). In this case there are no dosage recommendations in the product informations of antibiotics and literature data are scarce. The risk for therapy failure, development of resistance and adverse drug effects is elevated. Purpose Aim of the presented study was to find out if standard therapy of Linezolid (LZ) and Meropenem (MP) results in adequate plasma levels in surgical ICU patients receiving CVVHD(F). Materials and Methods Surgical ICU patients receiving CVVHD…
Gluteal Compartment Syndrome Following Abdominal Aortic Aneurysm Treatment: Case Report and Review of the Literature
2016
Compartment syndrome (CS) is a pathological increase of the interstitial pressure within the closed osseous fascial compartments. Trauma is the most common cause, followed by embolization, burns, and iatrogenic injuries; it usually involves the limbs. The major issue when dealing with CS is the possibility to do an early diagnosis in order to intervene precociously, through a fasciotomy, reducing the risk of tissue, vascular and nervous damage. Although it is an infrequent condition, it is potentially life threatening. In our case report, we present a 59-year-old patient, smoker, affected by hypertension, dyslipidemia, chronic renal failure, and morbid obesity who came at our attention for …
Intra-Dialytic Electrostimulation of Leg Extensors May Improve Exercise Tolerance and Quality of Life in Hemodialyzed Patients
2011
Hemodialyzed (HD) patients with end-stage renal disease (ESRD) exhibit lower fitness as a consequence of chronic uremic changes that trigger various structural, metabolic, and functional abnormalities in skeletal muscles. The aim of this randomized study was to compare the effect of rehabilitation (RHB) training on a bicycle ergometer and electromyostimulation (EMS) of leg extensors in HD patients with ESRD. Thirty-two HD patients (18 men/14 women; mean age 61.1 ± 8.8 years) were randomized into three groups: (i) exercise training (ET; n = 11) on bicycle ergometer 2 × 20 min; (ii) EMS (n = 11) where stimulation (10 Hz) of leg extensors was applied for 60 min; and (iii) controls (CON; n = 10…
Theoretical approach and clinical application of kinetic modelling in dialysis.
1991
Using kinetic modelling for shaping profile dialysis, we present a promising approach to improve the cardiovascular stability of patients during dialysis treatment. In order to obtain an insight into the physiological mechanisms of increased stability, a model considering alterations of electrolytes and water distribution and of acid-base status was developed. This algorithm was used for the evaluation of 114 dialysis sessions, which were performed with highly individualised profiles. Each profile was developed for one patient by trying empirically to prevent episodes of hypotension as well as other clinical problems throughout dialysis. The main advantage of profile dialysis compared to st…
Hepatitis C virus infection in hemodialyzed patients.
2007
In spite of our present improved knowledge of the epidemiology and pathways of contamination of the hepatitis C virus (HCV), infection still remains a public health problem. One category of patients who have suffered greatly from the consequences of HCV infection is certainly that of hemodialysis patients. In the past, in fact, their need for transfusions exposed these patients to infection and, as a result, subjects on dialysis for over 15 years are today paying the price for those inevitable transfusions, as the virus and its pathways of contagion were unknown then. However, still today, albeit at a much lower prevalence, even subjects with a shorter dialysis age present a higher prevalen…

The Impact of the Introduction of Innovative REDS Scale for the Evaluation of Central Tunnelled Catheter (CTC) Exit Site on Infection Prevention in L…
2021
Central tunneled catheter (CTC)-related infections are a leading cause of a catheter loss, thus being the source of significant morbidity and mortality. The study aims at evaluating the impact of the implementation of the innovative redness, edema, discharge and tenderness, symptoms (REDS) scale (devised by the authors) for the description of the tunnel condition on the frequency of infection in long-term catheter users. The same cohort of the 40 patients was observed for 4 years altogether: 2 years before and 2 years after REDS application. The results, as well as follow-up evaluation of participants, were compared. The 2-year cumulative incidence of the CTC exit site infection (ESI) dropp…
