Haemodyalisis

Hemodynamic changes during haemodialysis are common. Often these changes are associated with symptoms that are thought to be the result of reduced microcirculatory blood flow and oxygen delivery. The microcirculatory effect of hemodialysis is scarcely researched, though of possible influence on patient outcome. New techniques have become available to visualise and analyse microvascular blood flow. We performed an observational study using Sidestream Dark Field imaging, a microscopic technique using polarised light to visualise erythrocytes passing through sublingual capillaries, to analyse the effect of haemodyalisis on central microvascular blood flow...

Chronic haemodyalisis is an established treatment of end stage renal disease which maintains the lives of individuals who otherwise would have succumbed to a uraemic death. However, this method of treatment raises certain psychological, social and ethical issues, where depression and stress are the most common. This article is concerned with the evaluation of depression and the psychological characteristics of patients treated by chronic maintenance haemodyalisis. Using two psychometric tests (Beck Depression Inventory and MMPI-201) we obtained a significant incidence of depression (90...

PURPOSE: The purpose of this study was to reach conclusions about the diagnosis and treatment of a series of patients with spondylodiscitis under haemodialysis treatment. METHODS: We collected and studied 23 patients included in a prospective database from two neighbouring hospitals. Descriptive statistical analysis was performed. RESULTS: The diagnosis was frequently made very late and early negative cultures were not uncommon; magnetic resonance images allowed for an early diagnosis with accurate anatomical information...

Exercise as a therapeutic tool used in End-stage renal disease patients (ESRD) in hemodialysis (HD) is not routinately applied, as it occurs with cardiac or respiratory patients. Lack of awareness of research in this field may contribute to the current situation. Thus, the aims of this review are: 1) to systematically review the literature of exercise training on adult HD patients or patients at a pre-HD stage; 2) to show the evidence on the benefits of exercise for counteracting physiological, functional and psychological impairments found even in older ESRD patients; 3) to recommend requirements of future research in order to include exercise prescription in the HD patients treatment...

BACKGROUND: The measurement of i-PTH circulating is not easy due to its analytical variablity. Variability that appears in the process that goes from the sample collection to the final result determination. There are several important aspects that can influence within the pre-test variability: type of sample (serum o plasma), temperature, time elapses from blood extraction to freezing and from freezing to i-PTH quantification. Blood coming from centres far from our laboratory do not always meet the required processing conditions...

Late nephrology referral of patients with chronic kidney disease (CKD) has been suggested as increasing mortality after the initiation of dialysis. The aim of this study was to assess the impact of nephrology referral on the initiation of haemodyalisis (HD) and mortality during HD treatment in end-stage renal disease (ESRD) patients who have died in our institution over a five-year period. We studied data from all 117 patients on HD treatment in our institution who died (after 90 days of HD treatment) in the period between 01...

Protein Z (PZ) is a vitamin K dependent serine protease inhibitor, which along with its cofactor Protein Z-dependant protease inhibitor (ZPI) has anti-Xa activity. PZ has previously been reported to be elevated in patients with end-stage chronic kidney disease (CKD) on haemodialysis but not in non-dialysed CKD patients raising the possibility that PZ may have a role in the bleeding diathesis of patients on haemodyalisis. PZ was measured in controls (n = 18), CKD on haemodialysis (n = 23) and CKD not on dialysis (n = 23)...

Clinical case. This 27 year-old male was referred admitted with severe acute pancreatitis (SAP) after heavy consumption of alcohol and sepsis (bacteremia and multilobar pneumonia) due to methicillin-resistant Staphylococcus aureus (MRSA); he required mechanical ventilation and haemodyalisis, and developed fungemia by fluconazol-resistant Candida albicans. He was treated with caspofungin for 20 days and vancomycin for six weeks, and he was discharged after 51 days of hospitalization. This case shows the painful evolution of a patient admitted to the intensive care unit (ICU) with MRSA sepsis...

INTRODUCTION: The prosthesis nowadays used in the vascular access for haemodialysis have low patency rates, mainly due to the luminal obstruction, determined by the intimal hyperplasia. Several factors have been related to de development of intimal hyperplasia and graft failure. Among them are the differences in the biomechanical properties between the prosthesis and the native vessels. In the searching for vascular prosthesis that overcomes the limitations of the currently used, the cryopreserved vessels (cryografts) appear as an alternative of growing interest...

PURPOSE: The purpose of this study was to assess the effectiveness of Cutting Balloon angioplasty in the treatment of stenoses in haemodialysis arteriovenous accesses. MATERIALS AND METHODS: Over the past 2 years, we have observed 80 patients with stenotic haemodialysis accesses; 24 of these (mean age 66.4 years, range 50-81) with 26 stenoses of 24 accesses (21 Cimino-Brescia fistulas and 3 dialysis loops) were selected for Cutting Balloon angioplasty. In 11 cases, the Cutting Balloon device was used after failure to dilate the access with a high-pressure balloon whereas in 15 cases (10 focal stenoses and 5 restenoses), it was used as a first choice...

We present a case of IgA nephropathy diagnosed by renal biopsy that presents after 2 years of folow-up an impairment of the renal function associate histoligically to a crescentic glomerulonephritis. The immunologic determinations showed of high titers of antineutrophil cytoplamic antibodies (ANCA) (P-ANCA IgG antiMPO and P-ANCA IgA anti-MPO). The patient began treatment with haemodyalisis and one year later she received a cadaveric kidney transplantation with good result. Two years later she had normal urine sediment, negative proteinuria, normal renal function but high titers of IgG and IgA PANCA anti-MPO...

The aim of this study was to evaluate the effectiveness of the laparoscopic cholecystectomy performed in two uremic patients with gallstones. From January to July 2004, 15 patients with gallstones underwent to laparoscopic cholecystectomy (LC). Two patients had chronic renal failure on haemodyalisis: a symptomatic fourty-two old woman, which had primitive hyperparathyroidism and primitive hyperaldosteronism, and asymptomatic transplant candidate fifty-five old man. No minor and major complications occurred and both patients were discharged 4 days after LC...

In this article results are compared of the bovine graft and the Goretex graft as a shunt from an artery to a vein in view of the access to the circulation for haemodialysis. Drawing conclusions would seem premature as yet, but there seems to be some indication that the Goretex graft stays open more easily. In our opinion the Goretex graft is easier to handle during the operation. We want to point out once again that, in all probability, our ample experience with the Goretex graft plays a role in the evaluation of the outcome...

Dialysis and transplantation of the kidney have become in Czechoslovakia part of routine therapy of chronic renal failure (ChRF) in children and adolescents. The authors examined 16 children aged 4-17 years (x = 10.5) treated in a chronic dialyzation programme (ChDP) by haemodyalisis and 20 children after transplantation of a cadaverous kidney, age 4.5-16.5 years (x = 11.5), incl. 14 patients with a stable function of the graft and six patients during the period of acute rejection of the graft. The authors tested the basic parameters of humoral and cellular immunity in all three groups of children...

In cases of the malfunction of av-fistulae for haemodialyses a kind of prosthetic graft has to be used. Since 1973 alloplastic protheses (Sparks-Mandril) have been used in 7 patients, since 1976 heterologous (Solko-graft-calf-carotis) ones in 12 patients. In an average follow-up period of 18 months the heterologous prostheses proved to be more suitable because of longer patency-rates, simpler handling during surgery and earlier use for dialyses. As a major late complication only one case of an aneurysmatic enlargement was observed in one of the heterologous protheses...

Two cases of suicide of patients with renal insufficiency and haemodyalisis commited by liquidation of the shunt are reported. Authors stress the importance of prevention and psychotherapy among haemodyalized patients having depression and neurotic complications.

A case of severe multiple trauma sustained in a road accident is reported. The aim of the report is to show the determing role played by diagnostic and surgical methods and therapeutic possibilities available in the intensive care unit (shock treatment, controlled respiration, parenteral feeding, haemodialysis) in winning the five-months' battle for the life of the patient. Early haemodyalisis as supporting therapy in respiratory failure and conservation treatment of intestinal fistulae are important. Post-traumatic pancreatitis which is a not infrequent complicating feature of severe multiple trauma may present diagnostic difficulties...
