    Full Text Available Introduction: Sever daily sleepiness is one of the problems of patient with chronic renal failure. There are evidences indicating different sleep pathology in patients undergoing hemodialysis. This study was conducted to evaluate the effect of applying continuous monitoring model on sleepiness of hemodialysis patients in Shahinshahr/ Isfahan. Methods: This semi-experimental study was performed on 40 hemodialysis patients. Data gathering was done by Epwort Questionnaire. The questionnaire was used twice before the intervention with the interval of one month. The applied model contained four steps: orientation, sensitization, control and evaluation. Patients were divided into five groups and 4-6 training sessions during three weeks were held for each group and during the remained 9 weeks, consultations for continuous sleep monitoring, control and evaluation were performed. The questionnaire was filled out immediately after the intervention and one month later. Data were analyzed through SPSS 15 through descriptive and analytic statistics. Results: The study findings revealed that mean score of sleepiness before intervention was 11/06 (± 3/32. Therefore, after intervention it increased significantly to 5.54 (± 2/85 (P=0/0001. The percentage of sleepiness before the intervention was 74/4 that decreased significantly to 38/8 % (p = 0/0001. Conclusion: Using continuous care model as an ethnic model can reduce many problems of patients. It is recommended to study monitoring model more elaborately in order to utilize it on other hemodialysis patients.

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the changes in salivary gland function in patients with chronic renal failure (CRF) undergoing hemodialysis. The group consisted of 23 patients with CRF (13 female, 10 male; mean age: 40±13 yr) and 14 healthy control subjects (mean age: 40±13 yr). All underwent dynamic salivary gland scintigraphy with gustatory stimulation. After intravenous administration of 99mTc pertechnetate, first, perfusion images at 2 seconds per frame were acquired for 1 minute, then dynamic images at 1 minute per frame were acquired for 45 minutes. At 30 minutes after injection , 10 ml lemon juice was given for 15 minutes as a gustatory stimulus. We obtained time-activity curves derived from regions of interest centered over the four major salivary glands. The following functional indices were calculated for each gland: the time of maximum radioactivity (Tmax) for the prestimulated period, the time of minimum radioactivity (Tmin), as an indicator of velocity of secretion after stimulation, and the Lem E5% value as an indicator of the secretion function. When the patients with CRF undergoing hemodialysis were compared to the controls, there were statistically significant differences in Tmax, Tmin and Lem E5% values for bilateral parotid glands, and Tmin values for bilateral submandibular glands (pmaxlly significant differences in Tmax and Lem E5% values for bilateral submandibular glands. There were also significant differences in Tmax and Lem E5% values for bilateral parotid glands between mild oral problems and severe oral problems in patients with CRF (undergoing hemodialysis). In this study, prolonged Tmax and Tmin values, and decreased Lem E5% values for parotid glands and prolonged Tmin values for submandibular glands on salivary scintigraphy pointed out decreased parenchymatous and excretory function in patients with CRF undergoing hemodialysis.

    Full Text Available SciELO Brazil | Language: English Abstract in english OBJECTIVE: The present study was designed to analyze the serum levels of aspartate and alanine aminotransferases, gamma-glutamyl transferase, and the hematocrit in patients with chronic kidney disease who were undergoing peritoneal dialysis or hemodialysis. PATIENTS AND METHODS: Twenty patients on p [...] eritoneal dialysis and 40 on hemodialysis were assessed, and the patients were matched according to the length of time that they had been on dialysis. Blood samples were collected (both before and after the session for those on hemodialysis) to measure the enzymes and the hematocrit. RESULTS: In the samples from the patients who were undergoing peritoneal dialysis, the aspartate and alanine aminotransferase levels were slightly higher compared with the samples collected from the patients before the hemodialysis session and slightly lower compared with the samples collected after the hemodialysis session. The levels of gamma-glutamyl transferase in the hemodialysis patients were slightly higher than the levels in the patients who were undergoing peritoneal dialysis. In addition, the levels of aminotransferases and gamma-glutamyl transferase that were collected before the hemodialysis session were significantly lower than the values collected after the session. The hematocrit levels were significantly lower in the patients who were on peritoneal dialysis compared with the patients on hemodialysis (both before and after the hemodialysis session), and the levels were also significantly lower before hemodialysis compared with after hemodialysis. CONCLUSION: The aminotransferase levels in the patients who were undergoing peritoneal dialysis were slightly higher compared with the samples collected before the hemodialysis session, whereas the aminotransferase levels were slightly lower compared with the samples collected after the session. The hematocrits and the aminotransferase and gamma-glutamyl transferase levels of the samples collected after the hemodialysis session were significantly higher than the samples collected before the session. Taken together, the present data suggest that hemodilution could alter the serum levels of liver enzymes.

    The aim of this study was to evaluate the prevalence of aspirin resistance (AR) in patients undergoing hemodialysis (HD) and to assess the effect of HD on the results of the Multiplate test. A total of 54 patients undergoing HD were included in this study. Blood samples were taken just before and after the HD session. To determine AR, we used Multiplate test. Platelet aggregation values of the study population were 363.01 ± 225.69 aggregation unit (AU) × minutes before and 375.33 ± 254.05 AU × minutes after the HD (P = .597). There was strong correlation between the values before and after HD (R = .755, P < .0001). The AR status was changed in 9 (16.6%) patients after HD. Agreement of AR status before and after HD was substantial (? coefficient = .667, P < .0001). The prevalence of AR in patients undergoing HD seems higher than in most of the studied populations, and this study has shown that the AR statuses of a significant number of patients undergoing HD change after an HD session.

    An ammonium ion-specific electrode system is evaluated for analysis of blood urea nitrogen from serum, plasma ultrafiltrate, or hemodialyzer dialysate fluid. The electrode shows a high sensitivity over clinically useful concentration ranges. Free serum ammonia, volatile amines, or urea ammonia after hydrolysis can be measured. In a double blind study excellent correlation was found for 187 blood urea nitrogen samples measured with the electrode with standard auto-analyzer techniques. Continuous monitoring of urea in dialysate fluid is described. Urea clearances were measured from dialysate effluent from an in vitro dialysis using conventional equipment. These values show excellent correlation to those from stnadard analysis methods. A continuous urea sensor for on-line hemodialysis application which can provide quantification of therapy is described. PMID:357303

  10. Clearance and synthesis rates of beta 2-microglobulin in patients undergoing hemodialysis and in normal subjects

    International Nuclear Information System (INIS)

    Retention of ? 2-microglobulin in patients undergoing hemodialysis is associated with a ? 2-microglobulin-derived amyloidosis. Removal of ? 2-microglobulin by renal replacement therapy has been proposed for the prevention of this amyloidosis. Currently, however, data on the ? 2-microglobulin synthesis rate in patients undergoing hemodialysis are scarce, and consequently it remains speculative how much removal would be necessary to counterbalance synthesis. The plasma kinetics of iodine 131-labeled ? 2-microglobulin were therefore examined in 11 patients with anuria who were undergoing long-term hemodialysis. Five healthy persons served as controls. Kinetic modeling of the plasma curves showed that the data fitted a two-pool model (r2 greater than 0.96) consisting of a rapid 2 to 4 hour distribution phase followed by a less steep curve, described by the plasma (metabolic) clearance (Clp). Synthetic rates were calculated from Clp and the ? 2-microglobulin steady state plasma concentration (plus ? 2-microglobulin removal during hemodialysis in the case of high flux hemodialysis). The results showed a significantly higher Clp in normal controls as compared with patients undergoing hemodialysis (65.5 ± 12.8 ml/min (mean ± SD) versus 3.4 ± 0.7 ml/min). In contrast, the ? 2-microglobulin synthesis rate in the patient group (3.10 ± 0.79 mg/kg/day) was not significantly different from that of normal controls (2.40 ± 0.67 mg/kg/day), which was due to markedly elevaich was due to markedly elevated ? 2-microglobulin plasma concentrations in the patients (37.6 ± 14.1 mg/L vs 1.92 ± 0.27 mg/L). These findings suggest that the presence of end-stage renal disease does not have a significant impact on the beta 2-microglobulin generation rate

    Darbepoietin alfa (NESP) is a new long-acting erythropoietin, with a half-life 3 times longer than the old epoietins. In the present study, we evaluated the efficacy of NESP in a group of children on hemodialysis. Seven children, five male and two female, with a mean age of 11.5 +/- 3 years and a mean weight of 34.1 +/- 11 kg, were enrolled in the study. All had been treated for at least 6 months with epoietin alfa at a mean dose of 106 +/- 76 IU/kg 3 times/week i.v. They were then given NESP at a mean dose of 1.59 +/- 1.19 microg/kg once a week i.v., according to the suggested conversion index (weekly epoietin alfa dose/200=weekly NESP dose). Anemia was evaluated at the end of a dialysis session. This was especially important for children less compliant with water restriction. Serum ferritin and percentage transferrin saturation (TSAT) were also monitored, as were dialysis efficacy (Kt/V), blood pressure, and heparin requirements. Before starting the new treatment, all patients had an adequate mean hemoglobin (Hb) level (11.19 +/- 1.7 g/dl) and an adequate iron status (TSAT 24.2 +/- 11.5, serum ferritin 220 +/- 105 mg/dl). Five of the seven patients were also treated with intravenous ferric gluconate (10-20 mg/kg per week). Six children were on antihypertensive treatment. After the 1st month of treatment, we observed an excessive increase in Hb, 12.3 +/- 1.7 g/dl, (P13 g/dl). A short discontinuation of the medication, followed by restarting at a decreased dosage, allowed us to continue with the treatment. At the 2nd month of follow-up, a mean plasma Hb level of 12.2 +/- 1.2 g/dl was observed, with a NESP mean dose of 0.79 +/- 0.4 microg/kg per week. Steady state was reached at 3 months, with a mean Hb of 11.8 +/- 1.4 g/dl and a mean NESP dose of 0.51 +/- 0.18 microg/kg per week (P<0.05). These results persisted at 6 months of follow-up; only one child had a persistent increase in platelet level (373,000 vs. 555,000). Dialysis efficiency and heparin requirements during dialysis did not change significantly. The high efficacy of NESP allowed a consistent reduction in dosage. The suggested conversion index does not appear to be correct for pediatric patients. Our experience suggests that in this population the correct dose could be 0.25-0.75 microg/kg per week. Hypertension was the only major side effect reported. The influence of NESP on platelet proliferation needs to be further investigated. The single weekly administration of NESP could be effective and beneficial for both patients and clinicians. PMID:14745634

    Intermittent hemodynamic instability during hemodialysis treatment is a frequent complication in patients with end-stage renal failure. A noninvasive method for continuous hemodynamic monitoring is needed. We used noninvasive digital photoplethysmography and an algorithm for continuous, investigator-independent, automatic analysis of digital volume pulse in 10 healthy subjects and in 20 patients with end-stage renal failure during the hemodialysis session. The reflective index was defined representing the diastolic component of the digital pulse wave. The properties of the reflective index were studied in healthy control subjects (n=10). An increased reflective index was due to increased peripheral pulse wave reflection (e.g., vasoconstriction). During a hemodialysis session, the reflective index increased significantly from 36+/-3 arbitrary units to 41+/-3 arbitrary units (n=20; p

    The increased use of tunneled cuffed catheters in children on chronic hemodialysis is the result of their relative ease of insertion, pain-free dialysis and immediate use. The disadvantage of their use is that they are associated with catheter-related bacteremia (CRB), which in turn is related with increased morbidity, access loss and occasionally metastatic infections and even death. A CRB might be difficult to diagnose and is often associated with a previous history of CRB, exit-site infection, low serum albumin and long duration of catheter use. There is evidence that the use of arteriovenous fistulae is associated with lower infection rates. The implementation of effective strategies for the prevention of CRBs include the adoption of policies for improving arteriovenous fistula rates, appropriate surgical catheter insertion and optimal nursing care of the exit site, and a safe connection technique. Recently, the effectiveness of antimicrobial catheter solutions for preventing CRB has been documented in a number of randomized clinical trials. In addition, the application of antibiotic ointments at the exit sites of tunneled cuffed catheters might be significant for the reduction of Staphylococcus-related CRB. The upside is that education-based programs combining specific preventive measures can significantly reduce CRBs. PMID:21073289

    The objective of the present study was to evaluate the level of hope of elderly chronic kidney disease patients undergoing hemodialysis, using the Herth Hope Scale (HHS). This cross-sectional descriptive study was performed at a Renal Replacement Therapy Unit located in upstate São Paulo. The sample consisted of 50 elderly patients currently undergoing hemodialysis treatment. After obtaining the participants' consent to participate, individual interviews were performed with the elderly individuals, utilizing a characterization instrument and the Herth Hope Scale. All of the ethical premises were complied with (protocol 512/2009). Regarding the results, most participants were male (60%) and their mean age was 70.20 (±6.1) years. The mean score on the Herth Hope Scale was 36.20 (±2.90). In conclusion, compared with the Brazilian study regarding the validation of the Herth Hope Scale, the subjects' level of hope was lower, thus indicating a need to intervene regarding this feeling.

    The pharmacokinetics of metronidazole, its biologically active alcohol metabolite, and its inactive acid metabolite were studied in five noninfected patients undergoing continuous ambulatory peritoneal dialysis and five patients undergoing hemodialysis. The latter were studied on off-dialysis days as a control group. Peritoneal dialysis caused insignificant changes in the apparent volume of distribution, elimination half-life, and total body clearance of metronidazole. Peritoneal dialysis clearance (4.49 +/- 0.88 ml/kg per h [mean +/- standard deviation]) accounted for only 8.9% of total body clearance (50.17 +/- 18.64 ml/kg per h). Analysis of the 24-h area under the serum concentration versus time curves and peritoneal dialysis clearance data for the two metabolites suggested a similar insignificant effect of peritoneal dialysis on their elimination. Metronidazole dialysate concentrations in the first 6-h exchange ranged from 7.6 to 11.7 micrograms/ml. This would suggest that cumulative penetration of metronidazole from the systemic circulation into the peritoneal cavity with dosing every 8 h should lead to adequate concentrations for the treatment of anaerobic peritonitis. For the treatment of systemic anaerobic infections, it would appear at present that metronidazole dosage adjustments are not necessary in patients undergoing continuous ambulatory peritoneal dialysis. The potential for metabolite accumulation was noted in this study. If further studies confirm that excessive serum metabolite concentrations are toxic, dosage reduction in this group of patients may be warranted. PMID:6721462

    Full Text Available Background and Aims: Factors like hemodilution, pyridoxine deficiency, hepatocyte growth factor and uremic toxins have been proposed for low aminotransferase activity in chronic kidney disease (CKD patients undergoing haemodialysis. This may be a concerning factor in making diagnosis of liver disorders like hepatitis in patients undergoing haemodialysis. In present study we attempted to find out the cause of hypoaminotransferasemia in chronic kidney diseases and biochemical principle of analysis.Materials and Methods:  Serum levels of various biochemical parameters are measured in CKD patients undergoing haemodialysis. The serum activities of Aspartate Aminotransferase (AST and Alanine Aminotransferase (ALT are determined (with and without the addition of PLP in a group of 176 patients undergoing hemodialysisResults: Serum AST and ALT activities are significantly lower in the CKD patients compared to the control group (P value 0.0003 and 0.001 respectively. Measurement of activity with pyridoxal phosphate containing reagent resulted into a significant increase in values comparison to without pyridoxal phosphate. The percentage activation is higher in patients as compared to controls.Conclusion: The upper limit of reference range for aminotransferases in CKD patients undergoing hemodialysis should be considered lower as compared to healthy subjects. Reagent containing pyridoxal phosphate is considered appropriate for aminotransferase activity measurement.

    Caring for a patient undergoing hemodialysis is highly stressful and can negatively affect a caregiver's physical and psychological well-being. This study was conducted to examine the effect of educational support concerning caregiver burden and given to the caregivers of hemodialysis patients. This experimental study was performed with 122 caregivers. Patients' data were collected by means of Personal Information Form and Zarit Caregiver Burden Scale (ZCBS). Characteristics of caregivers of hemodialysis patients were analyzed descriptively in terms of frequencies and percentages for categorical data, means, and standard deviations. Mann-Whitney U test, Kruskall-Wallis test, and percentages were used in the data analysis. The mean ZCBS score was 52.1?±?8.6 (range, 0-88). Among the caregivers, the mean score of the ZCBS was significantly higher in women, single, young, family relatives as "daughter/sister/brother/daughter-in-law and town/district, high educational level (P?caregivers who have health problems/diseases. In addition, this study explored the educational needs of home-based such as nutrition (35.2%), dialysis (27.8%), fistula care (20.4%), catheter care (18.8%), the information about chronic kidney disease (18.0%), blood pressure (17.2%), weight control (17.2%), hygiene (3.1%), and travel/exercise (6.5%). The post-educational mean scores (55.0?±?7.6) of caregiver burden were observed to be lower than the pre-educational scores (43.9?±?5.2), and the difference was found to be statistically significant. The home-based educational program demonstrated a decrease in the burden of hemodialysis caregivers. PMID:23279118

    In the present study, a comparative evaluation of the effects of calcium acetate, calcium carbonate, sevelamer hydrochloride and lanthanum carbonate was carried out in 120 patients with end stage kidney disease (ESKD) undergoing hemodialysis. Biochemical parameters, like serum phosphorous, serum calcium and serum alkaline phosphatase level and intact parathyroid hormone level, were measured. A statistically significant reduction in serum phosphorous, serum calcium, calcium × phosphorous and serum alkaline phosphatase level were observed with all phosphate binders during 3 months of treatment. Reduction in serum phosphorous were observed with calcium acetate (1.5 mg/dL), calcium carbonate (1.3 mg/dL), sevelamer hydrochloride (2.1 mg/dL) and lanthanum carbonate (1.79 mg/dL). The reduction of serum alkaline phosphatase was observed more commonly with sevelamer (107.37 IU/L) and lanthanum (104.33 IU/L) treatments than with calcium acetate (93.9 IU/L) and calcium carbonate (86.57 IU/L). There was no statistically significant change in serum calcium observed with sevelamer and lanthanum treatments, while calcium-based phosphate binders caused a significant rise in the serum calcium level. Serum intact parathyroid hormone level was significantly reduced with all phosphate binder treatments. This decline was highest with sevelamer and lowest with calcium carbonate. All treatments were well tolerated and safety profiles were consistent with previous reports in hemodialysis patients. It is concluded that all phosphate binders are safe and effective for the treatment of hyperphosphatemia in patients with ESKD undergoing hemodialysis. However, sevelamer hydrochloride seems to be superior among all with lowering incidence of hypercalcemia. PMID:24821148

    Full Text Available Introduction. Hypertension is evident in 80%-85% of patients with chronic renal failure and antihypertensive therapy is needed in 25%-30% of patients. Apart from antihypertensive effect, ACEi’s decrease the left ventricular hypertrophy and mortality in dialysis patients. Even so, their use is limited due to hyperkalemia. Objective. The objective of the study was to compare the effect of fosinopril and enalapril on serum potassium level in hypertensive hemodialysis patients. Method. Prospective pilot study included 16 patients undergoing chronic hemodialysis, with mean age of 58.9±9.6 years and mean duration of hypertension 11.3±7.1 years. The effect of antihypertensive drugs of equivalent dose was followed during three periods (three months each: period 1 (therapy with enalapril, period 2 (therapy with fosinopril and period 3 (therapy with enalapril. Dialysis conditions were constant and patients were without signs of catabolic state. Laboratory results were followed on monthly basis and mean values were compared by ANOVA-one way test. Difference between variables between periods was tested using Bonferoni method. Results. There was significant difference between mean serum potassium levels throughout three therapeutic periods (5.88±0.38 vs. 4.99±0.44 vs. 5.46±0.46mmol/l; p<0.001. Difference was evident even in the first month of fosinopril therapy. The effect can not be explained by dialysis adequacy since Kt/ V was similar throughout three treatment periods (1.18±0.24 vs. 1.25±0.21 vs. 1.25±0.14; p=ns. Systolic blood pressure was regulated even better with fosinopril than with enalapril (187.5±21.4 mmHg vs.160.0±20.0 mmHg; p=0.01 and this effect was prolonged during period 3 (160.0±26.1mmHg. Hemoglobin values mainly depended on specific anemia therapy and not on particular ACEi drug. Conclusion. Fosinopril carries less risk of hyperkalemia in hypertensive hemodialysis patients than enalapril. Although definite conclusion may be drawn after well-designed studies, the results presented in this pilot study suggest that fosinopril may be recommended for hypertensive hemodialysis patients who are at risk to develop inter-dialytic hyperkalemia.

    A male patient undergoing hemodialysis in whom the cause of severe hyperkalemia (more than 8 mmol/liter) was found to be an unusual pica is described. His pica consisted of ingestion of burnt match heads (cautopyreiophagia). The potassium content of his daily consumption of burnt matches added 80 mmol to his 45 mmol dietary potassium intake. Hypogeusia and hypozincemia were documented. Oral zinc supplementation (zinc sulfate 220 mg per day for 10 weeks) normalized his plasma zinc level and taste acuity. He abandoned his pica and his plasma potassium level dropped significantly to 5.5 to 6 mmol/liter. It is suggested that inquiry about pica should be part of the dietary history in patients with renal failure. PMID:4050837

    The purpose of this study was to investigate the correlation of conjunctival and corneal calcification (CCC) with cardiovascular calcification in patients undergoing maintenance hemodialysis (MHD). A total of 122 patients undergoing MHD in our hospital were included in this study. Conjunctival and corneal calcification was examined by slit lamp and graded. Abdominal aortic calcification (AAC), aortic valve calcification (AVC), and mitral valve calcification (MVC) were determined by X-ray or ultrasound. The correlation of CCC with AAC, AVC, and MVC was analyzed. Biochemical, hematological, and cardiovascular data were compared between patients with different severity of CCC or AAC. Mitral valve calcification was significantly associated with AAC in our patients. Conjunctival and corneal calcification positively correlated with AAC. We also found that patients with severe CCC exhibited significantly higher levels of serum calcium, phosphate, product of calcium and phosphate, serum copper, cystatin, intact parathyroid hormone, and vitamin D than patients with mild CCC. In addition to significantly increased levels of serum calcium, product of calcium and phosphate, serum copper, and cystatin, patients with severe AAC also had higher high-sensitivity C-reactive protein level and greater left ventricular posterior wall thickness and left ventricular end-diastolic interventricular septum thickness than patients with mild AAC. Our results suggest that patients undergoing MHD with severe CCC or AAC have high degree of mineral metabolism disorder, inflammation, and cardiovascular function disorder. The strong correlation between CCC and AAC indicates that CCC score might be used as an indirect indicator to predict cardiovascular risks in patients undergoing MHD. PMID:25377787

This study investigates the role of alpha-lipoic acid (ALA in end stage renal disease patients undergoing hemodialysis. By the virtue of its antioxidative effects, ALA is expected to act as an erythropoietin (EPO adjuvant, and also has extended beneficial effects on endothelial dysfunction.Methods: Forty-four patients undergoing hemodialysis and receiving EPO were randomized into two groups: the first group received ALA 600 mg once daily for 3 months; while the other group represented the control group. Parameters measured at baseline and at end of study were hemoglobin, EPO doses, EPO resistance index (ERI, iron store indices, malondialdehyde, oxidized low-density lipoprotein (ox-LDL, interleukin-6 (IL-6, tumor necrosis factor-? (TNF-?, and asymmetric dimethylarginine (ADMA, as well as routine laboratory follow-up.Results: EPO doses and ERI were significantly decreased in the treatment group, while they did not change in the control group. Hemoglobin, iron store indices, malondialdehyde, oxidized ox-LDL, IL-6, TNF-?, and ADMA were similar in both treatment and control groups at baseline, and did not change by the end of study period. Likewise, routine laboratory measures were not affected by the treatment.Conclusion: ALA could be used in hemodialysis patients to reduce requirements for EPO. However, larger and longer term studies are required to clarify the exact role of ALA in hemodialysis as well as in pre-hemodialysis patients.Keywords: alpha-lipoic acid, anemia, asymmetric dimethylarginine, erythropoietin, hemodialysis, oxidative stress

    Objectives: Infection is a common cause of death among hemodialysis patients. The study investigated incidence, risk factors, clinical features and outcome of bloodstream infections (BSIs) in haemodialysis patients. Methods: The records of haemodialysis patients from 1999 to 2005 were reviewed. Risk factors were investigated by multivariate analysis. Results: There were identified 148 bacteremic episodes, in 102 patients. The BSI rate was 0.52 per 1000 patient-days. Of the 148 episodes, 34 occurred in patients with permanent fistulae (0.18/1000 patient-days); 19 in patients with grafts (0.39/1000 patient-days); 28 in patients with permanent tunneled central catheters (1.03/1000 patient-days); and 67 in those with temporary-catheter (3.18/1000 patient-days). With fistula as reference, the BSI ratio was 1.84 with arteriovenous graft (P=.029), 4.85 with permanent central venous catheter (P<.001), and 14.88 with temporary catheter (P <.001). Catheter related were 41 episodes (28%). Gram positive organism were responsible for 96 episodes (65%), with S. aureus ( 55%) the most frequent, followed by S. epidermidis (26%) and Gram-negative for 36 (23%), with E. coli (39%) the most frequent. Infection was polymicrobial in 14 (9.5%). Diabetes (p<0.001), low serum albumin (p=0.040) and low hemoglobin (p<0.001) were significant risk factors. During hospitalization 18 patients (18%) died. Septic shock (p<0.001) and polymicrobial infection (p=0.041) were associated with in-hospital mortality. Conclusion: The risk of BSI in patients undergoing hemodialysis is related to the catheter type and vascular access. Septic shock and polymicrobial infection predispose to unfavourable outcome.

  7. Changes of the cerebral metabolite patterns in patients undergoing hemodialysis due to chronic renal failure: evaluation with proton magnetic resonance spectroscopy

    International Nuclear Information System (INIS)

    We wanted to evaluate the cerebral metabolites in patients with chronic renal failure (CRF) and who were undergoing hemodialysis by performing proton MR spectroscopy and were wanted to evaluate the correlation between the changes in the cerebral metabolite ratios and the duration after starting the initial hemodialysis. Proton MR spectroscopy was performed in 15 patients with CRF and who were undergoing hemodialysis and in ten healthy volunteers. The changes in N-acetylaspartate (NAA), choline-containing compounds (Cho), myo-inositol (Myo), glutamine/glutamate complex (Glx), and creatine (Cr) were analyzed. MR spectroscopy was performed before and after hemodialysis. For the patients with CRF before hemodialysis, the Cho/Cr ratio in the gray matter (? < 0.001) and the Myo/Cr ratio in both the gray and white matter (? < 0.01) were significantly elevated compared with those in the control subjects. For the patients with CRF after hemodialysis, their Cho/Cr ratios were significantly reduced in both the gray and white matter compared with that before hemodialysis (? < 0.05). There was a significant positive correlation between the Cho/Cr ratio and serum Cr in the gray matter of CRF patients after hemodialysis (r = 0.54, ? < 0.05). The cerebral metabolite ratios were not significantly correlated with the duration after starting the initial hemodialysis. The cerebral metabolite patterns are significantly different between the patients with CRF and who are undergoing hemts with CRF and who are undergoing hemodialysis and the normal controls. The cerebral metabolite ratios are not significantly correlated with the duration after starting the initial hemodialysis

    Metabolic syndrome confers an increased risk of cardiovascular disease (CVD) in the general population. The relationship between adiponectins, and clinical outcomes in patients undergoing hemodialysis remains controversial. We investigated whether adiponectins, biomarkers of inflammation, nutrition status and clinical features predict the mortality of patients undergoing hemodialysis for 6 years. We measured baseline plasma total and high-molecular-weight (HMW) adiponectins, tumor necrosis factor (TNF)-?, serum high sensitivity C-reactive protein (hsCRP), and clinical characteristics including visceral fat area (VFA) and the Geriatric Nutritional Risk Index (GNRI) in 133 patients undergoing chronic hemodialysis. Forty-one of the 133 patients died during follow-up. The deceased patients were significantly older, had more prior CVD and diabetes, higher TNF-? and hsCRP levels but lower GNRI. VFA, and total and HMW adiponectin did not significantly differ between the two groups. TNF-? and hsCRP levels and GNRI score were significant for predicting all-cause and cardiovascular mortality in receiver operating curve analyses. When stratified by a GNRI score of 96, Cox proportional hazards analyses identified TNF-? as a significant predictor of all-cause mortality (hazard ratio [HR] 1.23; P?=?0.038) and hsCRP as a significant predictor of all-cause and cardiovascular mortality (HR, 2.32, P?=?0.003; HR 2.30, P?=?0.012, respectively) after adjusting for age, sex, diabetes mellitus, and prior CVD, only in malnourished patients. These results demonstrate that malnutrition and the inflammatory markers TNF-? and hsCRP, but not metabolic markers, including VFA and adiponectins have a significant impact on 6-year all-cause and cardiovascular mortality in Japanese patients undergoing hemodialysis.

    We aimed to study the vascular outcomes in hemodialysis (HD) patients based on their diabetic status. A cohort observational study was conducted among patients undergoing regular HD with a 5-year follow-up. Of the 252 consecutive HD patients, 60% were diabetic. Compared with nondiabetics, diabetics were 11 years older, 4 years lesser on HD, and more likely to have prior cerebrovascular and coronary artery disease (CAD). Overall 5-year follow-up showed that diabetic patients had higher rates of HD vascular accesses (57% vs 41%, P = .01), CAD (64% vs 33%, P = .001), major amputations (8.6% vs 0%, P = .003), and mortality (66% vs 23%, P = .001). On multivariate analysis, independent predictors of mortality included number of vascular accesses in nondiabetics and HD duration, CAD, and peripheral artery disease in diabetic patients. Diabetes mellitus is associated with a significant vascular burden and mortality among HD patients. Moreover, our finding highlights the vascular impact of renal failure and HD. PMID:24576984

    Twelve men and nine women undergoing chronic hemodialysis were studied to evaluate folate intake and status in relation to use of folate supplements. Because of possible folate-zinc interactions, zinc status was also evaluated. The patients were classified into four groups based on daily supplementation: no folate or zinc, 22.5 mg zinc, 5 mg folate, and 5 mg folate and 22.5 mg zinc. A food frequency questionnaire was developed to estimate average daily intakes of folate and zinc. Patients' mean dietary folate intake was 30% or more above the Recommended Dietary Allowance (RDA), whereas their mean dietary zinc intake was close to the RDA. No significant differences in dietary folate or zinc intakes existed among groups. Red blood cell (RBC) folate levels of folate-supplemented patients were approximately 10 times higher than those of patients who did not receive folate and who had normal RBC folate levels. Serum zinc levels in all four groups of patients were close to the lower limit of the normal range and were unaffected by supplementation; however, hair zinc levels of six zinc-supplemented patients were significantly higher than those of healthy unsupplemented control patients. Generalization of this study's findings are limited by its descriptive nature; nevertheless, for these patients and presumably for similar patients who also have adequate dietary folate intakes, high-dose folate supplementation does not appear to be necessary to maintain normal folate status. No evidence of a folate-zinc interaction was obtained; however, serum zinc may not be a valid index of zinc status in these patients. PMID:1573139

    Insufficient control of serum calcium and phosphate levels in patients undergoing hemodialysis is associated with increased mortality. As commonly used calcium-containing phosphate binders can cause arterial calcification, newly developed calcium-free phosphate binders, such as sevelamer hydrochloride (SH) and lanthanum carbonate (LC), have received much attention. We assessed the efficacy and safety of SH and LC treatment in Japanese patients undergoing hemodialysis in a prospective randomized open blinded endpoint (PROBE) crossover study. Forty-two patients were randomized to receive SH or LC for 13 weeks, with the dosages adjusted every 2 weeks, followed by treatment with the other drug for another 13 weeks. The average daily doses of SH and LC were 2971 ± 1464 mg and 945 ± 449 mg, respectively. The mean dosage ratio of SH to LC was 3.05, which was maintained throughout the treatment period. SH and LC were similarly effective at controlling serum calcium and phosphate levels in the majority of patients (78-93%). A few serious adverse events (AEs) involving the biliary system occurred during the LC treatment period, but they were not considered to be treatment-induced. Although the incidence of constipation, the most common treatment-related AE, was higher during the SH period (27% vs. 5%; P < 0.05), no difference was observed in total treatment-related AEs. This study demonstrates that SH and LC are comparable treatments for controlling serum phosphate and calcium levels, and that both compounds are safe and well-tolerated in Japanese patients undergoing hemodialysis.

    Some Authors found changes in plasma aminoacids concentration in patients with chronic renal failure treated with conservative therapy or with dialysis. Particularly they observed a reduction in the concentration of essential aminoacids (EAA) and an increase of the non essential (NEAA), with increase in their ratio. In our study we analyzed the plasma aminoacids pools in 12 children with chronic renal failure treated with hemodialysis. We have measured the plasma aminoacids concentrations before and after hemodialysis to evaluate their variations and their role in the pathogenesis of some symptoms of uremia. A decreased concentration of EAA and an increased concentration of NEAA, before hemodialysis, were observed. These findings were not modified by this therapy, but turned out to be related to protein intake. PMID:6518104

    Full Text Available To investigate the effect of cool dialysis on hemodynamic parameters and serum nitric oxide levels in diabetic patients, we studied 20 old (mean age 63.3 ± 7.5 chronic hemodialysis diabetics who were dialyzed twice, once using cool and once using standard (37 o C temperature dialysate solution. During the study, all the dialysis conditions were maintained the same except coo-ling the dialysate from 37 o C to 35°C. Hemodynamic parameters including SBP, DBP, and HR were measured hourly. Oral temperature was measured before and after dialysis. Serum urea and nitric oxide metabolites were determined before and after hemodialysis. Systolic, diastolic, and mean arterial pressure decreased significantly during standard temperature compared to cool dialysis. Maximum decrease of systolic, diastolic, and mean arterial pressure was observed during the third hour of dia-lysis and the magnitude of decrease was 18, 17, and 14 percent for standard temperature and 6, 1, and 4 percent for cool dialysis, respectively. Heart rate did not differ significantly between the two study groups. Compared to the pre dialysis levels of serum nitric oxide metabolites, the post dialy-sis levels decreased significantly with cool and standard temperature dialysate (59 ± 5 vs. 37 ± 4, and 63 ± 7 vs. 41 ± 5, µmol/L respectively, P< 0.01. Cool dialysis could decrease episodes of hypotension and stabilized hemodynamic parameters in diabetic patients. Probably other mechanisms than in-creased serum nitric oxide levels may be involved in hemodialysis hypotension in this group of patients.

    Full Text Available Background: Recent interests have mainly focused on the roles of serum calcium and phosphorus and their product (Ca-P product in the development of valvular heart disease. The present study assessed the relationship between the Ca-P product and the severity of valvular heart disease in end-stage renal disease (ESRD patients undergoing chronic hemodialysis.Methods: This cross-sectional study reviewed the clinical course of 72 consecutive patients with the final diagnosis of ESRD candidated for chronic hemodialysis. The severity of valvular heart disease was determined using M-mode two-dimensional echocardiography. The serum calcium and phosphate values adopted were those values measured on the day between the two consecutive dialyses, and the Ca-P product was calculated.Results: The most common causes of ESRD were diabetic nephropathy, malignant hypertension, and chronic glomerulonephritis. The mean Ca-P product level in the dialysis patients was 50.44 ± 17.78 mg2/dL2. The receiver-operator characteristic (ROC curve illustrated that a Ca-P product level > 42 mg2/dL2 was the optimal value in terms of sensitivity and specificity for predicting the presence of valvular insufficiency. Aortic insufficiency was directly associated with a high Ca-P product value after adjustment for age, gender, serum albumin, diabetes, hypertension, hyperlipidemia, coronary artery disease, and serum creatinine (? = 0.412, SE = 158, p value= 0.011.Conclusion: A positive relationship between the Ca-P product value and the severity of aortic insufficiency is expected. Achieving an appropriate control of the Ca-P product level may decrease aortic valve calcification and improve the survival of patients on chronic hemodialysis.

    Full Text Available Abstract Background Tissue injury due to hypoxia and/or free radicals is common in a variety of disease processes. This cross-sectional study aimed to investigate effect of chronic kidney diseases (CKD and hemodialysis (HD on hypoxia and oxidative stress biomarkers. Methods Forty pediatric patients with CKD on HD and 20 healthy children were recruited. Plasma hypoxia induced factor-1? (HIF-1?, vascular endothelial growth factor (VEGF were measured by specific ELISA kits while, total antioxidant capacity (TAC, total peroxide (TPX, pyruvate and lactate by enzymatic/chemical colorimetric methods. Oxidative stress index (OSI and lactate/pyruvate (L/P ratio were calculated. Results TAC was significantly lower while TPX, OSI and VEGF were higher in patients at before- and after-dialysis session than controls. Lactate and HIF-1? levels were significantly higher at before-dialysis session than controls. Before dialysis, TAC and L/P ratio were lower than after-dialysis. In before-dialysis session, VEGF correlated positively with pyruvate, HIF-1? and OSI correlated positively with TPX, but, negatively with TAC. In after-dialysis session, HIF-1? correlated negatively with TPX and OSI; while, OSI correlated positively with TPX. Conclusions CKD patients succumb considerable tissue hypoxia with oxidative stress. Hemodialysis ameliorated hypoxia but lowered antioxidants as evidenced by decreased levels of HIF-1? and TAC at before- compared to after-dialysis levels.

    Full Text Available Introduction: To describe the outcome of the sapheno-femoral fistula as an alternative blood access site for maintenance hemodialysis in a prospective cohort of patients with end - stage renal failure. Methods: Twenty-two patients with vascular access failure in the arms were admitted for establishing sapheno-femoral fistula as a puncture site for hemodialysis. The major saphenous vein was exposed at the junction site with femoral vein and its tributary veins were ligated . The saphenous vein was isolated and mobilized throughout the thigh and end to side anastomosis accomplished with the superficial femoral artery by a running 6-0 prolene suture after conducting the vein through a subcutaneous tunnel. Results: Failure rate of saphenofemoral fistula was 22. 7% at two years follow up. Mean ± SE survival of fistula was 16.4+/- 2.75 months. Significant survival difference wasn’t seen between two sexes. Rate of wound infection and chronic pain of surgery site was similar( 9.1%. Conclusions: Two-year survival rate of 77% and morbidity less than 10% leads to suggestion of saphenofemoral fistula as an alternative for upper extremity fistulas in end- stage renal failure patients

At least three intriguing pathways, ie, accumulation of protein-bound toxins, endotoxin translocation, and altered mucosal defense mechanisms, have been proposed to explain the inherent susceptibility of CKD patients to developing ischemia-related and cardiovascular events. Interestingly, all the proposed pathways can be potentially antagonized or attenuated. At present, however, it is not known whether one pathway predominates or if any interaction exists between these pathways. More solid experimental and clinical data are warranted to acquire a better insight into the complex pathogenesis of CKD-associated ischemia.

    Cardiac hypertrophy and arterial dysfunction have been described in end-stage renal disease (ESDR) in adults. The incremental elastic modulus (Einc), is a marker of vascular wall material stiffness and an independant predictor of cardiovascular mortality in adults with ESRD on hemodialysis. The relationship between arterial changes and the heart is unknown in the children with ESRD in the same conditions. Using a high-resolution vascular ultrasound and a computerized system of measurement (Iotec), we assessed noninvasively 10 ESRD patients (mean +/- SD, age, 11.5 +/- 4 years; blood pressure [BP], 120 +/- 10/63 +/- 4 mmHg) and 10 age-, sex-, and BP-matched controls (mean +/- SD, age, 11 +/- 4 years; BP, 114 +/- 8/58 +/- 8 mmHg). The systolic and diastolic diameter of the common carotid artery (CCA), the thickness of the wall (intima-media thickness, IMT), the cross sectional compliance (CSC), the cross sectional distensibility (CSD) and the (Einc) were determined. CSC and CSD were evaluated at the same level of pressure. The CCA pressure waveform was obtained by applanation tonometry to assess the reflected wave by the augmentation index (AI). Further the left ventricular mass index was assessed. The flow mediated dilation (FMD) (endothelium-dependent function) and the vasodilation induced by glyceryl-trinitrate (GTNMD) (GTN, an endothelium-independent dilator) were evaluated at the brachial artery site. Compared to control subjects, ESRD patients have mechanical artery dysfunction with lower CSC and CSD (0.11 +/- 0.04 vs 0.18 +/- 0.05 mm2.mmHg-1; p < 0.01; 0.43 +/- 0.10 vs 0.82 +/- 0.20 mmHg-1.10(-2); p < 0.001) and higher Einc (2.60 +/- 1.00 vs 1.40 +/- 0.30 mmHg.10(3); p < 0.001). Furthermore an earlier return of the reflected pulse wave (AI -0.24 +/- 0.08 vs -0.58 +/- 0.06; p < 0.005) is correlated to LV mass index (r = 0.55, P < 0.01) that is significantly increased (134 +/- 63 vs 69 +/- 25 g/m2; p < 0.005). These patients have an impaired FMD (4 +/- 2 vs 7 +/- 1%; p = 0.02) with a normal GTNMD. This study shows that early arterial dysfunction can occur in children with ESRD. PMID:10989747

    This study demonstrates a technique to measure electrical resistivity of the calf in hemodialysis (HD) patients during HD treatment. To continuously monitor and calculate resistivity, a model of calf volume based on its geometrical size and measurement of its electrical resistance has been developed. The model makes it possible to continuously estimate reduction of the calf circumference during HD. Seventeen HD patients were studied during HD using a multi-frequency bioimpedance device (Xitron 4200). Circumference of the calf was measured by a measuring tape pre- and post- HD for each treatment. Results showed a high correlation between measurement and calculation circumference in post HD (r(2)=0.985). Further, the value of resistivity normalized by body mass index (BMI) provides information about patients' hydration state in comparison to those in healthy subjects. This technique is useful for identifying the range of optimal hydration states for HD patients. PMID:17946679

    Full Text Available OBJECTIVE: Acute kidney injury (AKI is a frequent complication of hospitalized patients that is associated with high mortality rate despite all developments. Continuous and intermittent hemodialysis are renal replacement treatment modalities for AKI. In our study we aimed to compare the mortality rates of continuous hemodialysis (CHD and intermittent hemodialysis (IHD in hospitalized patients.MATERIAL and METHODS: Seventy-two patients in Uludag University Hospital diagnosed with AKI in 2008 were enrolled our study. Intermittent or continuous hemodialysis was prescribed by the nephrology counsultant. Data were recorded from patients files retrospectively.RESULTS: Patients were divided into two groups (38 IHD, 34 CHD. Mortality rate (52,6%, 88,2%, oligoanuria (63.2%, 94.1%, positive inotrope therapy (28.9%, 85.3%, sepsis (15.8%, 55.9%, mechanical ventilation (15.8%, 76.5%, rate of surgery (2.6%, 32.4% and the SOFA score (7.1, 9.5 were significantly higher in CHD group.CONCLUSION: The mortality rate was higher in CHD group, and this might be associated with the greater severity of problems such as hemodynamic instability, multi-organ dysfunction and co-morbid diseases in this group.

Além disso, a infecção pelo vírus da hepatite C (HCV), comum nestes pacientes [...] , seria outro fator de piora do estado inflamatório. Níveis aumentados de marcadores de disfunção endotelial são encontrados em pacientes com DRC e hepatite C, e poderiam ser importantes marcadores de aterosclerose nestes indivíduos. OBJETIVO: Comparar atividade endotelial de pacientes em hemodiálise com e sem hepatite C. METODOLOGIA: Selecionamos 28 pacientes em hemodiálise que foram divididos em dois grupos: 1-HCV(+): 18 pacientes (anti-HCV[+] e PCR[+]) e 2-HCV(-): 10 pacientes (anti-HCV[-]). Antes da primeira diálise da semana foi coletada amostra de sangue para dosagem sérica de molécula de adesão intercelular-1 (ICAM-1), fator de crescimento vascular endotelial (VEGF), aspartato alanina aminotransferase (ALT) e tempo de atividade da protrombina (TAP) dos grupos. RESULTADOS: Os níveis de ICAM-1 foram elevados em 60,71%, sendo maiores no grupo HCV(+), porém não estatisticamente significativos (p = 0,2024). Não houve correlação entre os níveis de ICAM-1 e tempo de diálise ou níveis de ALT em nenhum dos grupos. Já os níveis de VEGF foram normais em 92,85%; apenas dois pacientes HCV(+) tinham níveis elevados. Também não houve correlação com tempo de diálise ou níveis de ALT em nenhum grupo. CONCLUSÃO: Pacientes em hemodiálise possuem elevada lesão endotelial, porém a presença de infecção crônica pelo HCV não se mostrou um fator agravante deste quadro. Este resultado pode ter ocorrido por conta do pequeno número de pacientes, sendo necessárias análises com maior número de indivíduos para conclusões mais definitivas. Abstract in english INTRODUCTION: Chronic renal patients undergoing hemodialysis treatment have cardiovascular atherosclerotic disease as the main cause of death. Inflammation and endothelial dysfunction are directly associated with atherosclerosis. Furthermore, the infection resulting from hepatitis C virus, common am [...] ong such patients, would be another worsening factor of the inflammatory state. Increased levels of endothelial dysfunction markers are found in chronic renal disease and hepatitis C, which could be important markers of atherosclerosis among these subjects. OBJECTIVE: To compare endothelial activity in patients undergoing hemodialysis with and without hepatitis C. METHODOLOGY: We selected 28 patients undergoing hemodialysis and classified them into two groups: 1-HCV(+): 18 patients (anti-HCV[+] and PCR[+]) and 2-HCV(-): 10 patients (anti-HCV[-]). Before the first weekly dialysis, blood samples from both groups were collected for ICAM-1, VEGF, ALT and TAP serum dosage. RESULTS: ICAM-1 levels were high in 60.71%. The highest levels were found in HCV(+) group, though not statistically significant (p = 0.2024). There was no correlation between ICAM-1 levels and the hemodialysis time or ALT levels in any group. On the other hand, VEGF levels were normal in 92.85%. Only two patients HCV(+) had high levels. There was also no correlation between VEGF levels and the dialysis time or ALT levels. CONCLUSION: Patients undergoing hemodialysis have high endothelial lesion, nevertheless, the presence of HCV chronic infection did not prove to be an aggravating factor. This result may be due to the small number of patients, hence further analyses with a larger sample are required for definitive conclusions.

    Full Text Available Background: The kidney is a complex and vital organ, regulating the electrolyte and fluid status of the human body. In clients with a chronic disease, such as end-stage renal disease, functioning status and hematologic indexes are different than among the general population. Electrolyte and hematologic changes may induce many illnesses for such patients. The purpose of this study is to determine the effects of applying the continuous hemodialysis (HD the blood test results of HD patients.Methods: This quasi-experimental, before-after study included 38 HD patients from Hamedan, Iran in 2005. Subjects were selected using simple randomized sampling and were assigned to one group for the purpose of this research and investigated over a period of six months. Data collection tools included demographic questionnaire and control check lists. The first phase of the research involved orientation of the control group, which was limited to completion of the questionnaires and control check lists. Immediately after, the same patients became the case group, upon which continuous HD was applied and hemoglobin, hematocrit, blood urea nitrogen (BUN, potassium, sodium, and albumin tests were performed. Statistical analysis of the data employed SPSS (version 13, descriptive statistics, paired t-test and the Friedman test.Results: In this group, 47.2% of the subjects were male and 52.8% female. Data analysis shows that, using repeated measurement ANOVA test, a significant relationship between application of the continuous HD and improvement in hemoglobin, hematocrit, BUN, potassium, sodium, and albumin levels (p<0.05. conclusion: Application of continuous HD causes a significant improvement in the blood test results of HD patients. We recommend that continuous HD be used, whenever appropriate, to resolve the common causes of complications in HD clients, including abnormal levels of electrolytes, especially potassium and phosphorus, as well as BUN and creatinine.

    The maximum incidence of multiple myeloma appears in the 6th-7th decade of life and although the number of patients aged les than 60 years is increasing in recent years, the diagnosis of a monoclonal gammopathy in a young patient, under the age of 40 years remains a rarity. Literature data cite an incidence of approximately 2.2% in patients less than 40-year-old and an incidence of 0.3% in patients less than 30-year-old of all cases diagnosed with multiple myeloma. We present the case of a 32-year-old patient, being on continuous hemodialysis for chronic kidney failure for about a year, at the Hematology Clinic of Craiova, Romania. We investigate the origin of a serum monoclonal component revealed when performing serum protein electrophoresis. Bone marrow examination revealed the presence of a plasma cell infiltrate of 18%, which associated with the presence of a serum monoclonal component and in the conditions of renal failure as a complication of the disease, has allowed the diagnosis of multiple myeloma.

Results: The aTPT ratio at time 0 was 1.22 ± 0.49, from these, 13 patients (41.94%) started the hemodialysis with abnormal aTPT ratio. At 5’and 60’, all the patients showed values of aTPT ratio higher than 6.9 (aTPT > 300 seconds); at 120’ eleven of these (35.8%) had aTPT ratio higher than 6.9 and 20 patients (64.52%) showed an aTPT ratio of 5.59 ± 1.35; all of them over the recommended interval. At the end of the procedure, the mean of the aTPT ratio was 2.17 ± 0.75 and only 3 patients showed aTPT ratio under the anticoagulation interval. We observed two cases of macroscopic bleeding without complications, and there were no contraindications for the reuse of the dializers. Conclusion: The use of UFH in one bolus dose during hemodialysis showed anticoagulation levels higher than the upper limit of the therapeutic range, which persist up to the end of the procedure. It is recommended to stop the practice of this method.(Rev Med Hered 2011;22:103-107).

    The serum bicarbonate (HCO3(-)) levels are decreased in chronic hemodialysis (HD) patients treated with sevelamer hydrochloride (SH). We assessed the effects of bixalomer on the chronic metabolic acidosis in these patients. We examined 12 of the 122 consecutive Japanese patients with end-stage renal disease on HD, who orally ingested a dose of SH (?2250?mg), and an arterial blood gas analysis and biochemical analysis were performed before HD. Patients whose serum HCO3(-) levels were under 18?mmol/L were changed from SH to the same dose of bixalomer. A total of 12 patients were treated with a large amount of SH. Metabolic acidosis (a serum HCO3(-) level under 18?mmol/L) was found in eight patients. These patients were also treated with or without small dose of calcium carbonate (1.2?±?1.1?g). The dose of SH was changed to that of bixalomer. After 1 month, the serum HCO3(-) levels increased from 16.3?±?1.4 to 19.6?±?1.7?mmol/L (P?

Generally, the study population had low socioeconomic status, limited access to private health services, high rate of comorbidities, and received a large number of dietary recommendations, which were not necessarily appropriate. According to multivariate analysis, the risk factors for malnutrition were age over 60 years, family income at or below one minimum wage, presence of depression, and retirement. CONCLUSION: Malnutrition is prevalent among patients undergoing hemodialysis. Differences in socioeconomic, demographic, clinical, and general characteristics can be used to identify patients who require more attention due to the risk of malnutrition, particularly in the elderly, retirees, and those with depression and low socioeconomic status.

    Full Text Available Introduction. Patients with end-stage renal failure have high morbidity and mortality rates due to cardiovascular complications. Screening for coronary heart disease in these patients is of utmost importance. The aim of this study was to investigate the prognostic value of the dobutamine test in patients on hemodyalisis during a 5-year follow-up period. Material and methods. During the pretransplantation period, 24 patients on chronic hemodialysis underwent echocardiography and dobutamine echocardiography. The average age of patients was 51.50±7.35 years. The mean duration of dialysis was 74±40 months. Results. The dobutamine stress test was positive in 50% of patients, and undefined in 12.5%. The wall motion score index before the test was 1, and after the test it was 1.54±0.27. There were no serious complications. Left ventricular mass, diastolic and systolic dimension and posterior wall were significantly higher in patients with positive dobutamine stress results and they were associated with late cardiac morbidity and mortality. Five-year survival in patients with positive dobutamine stress results was 33.3% and 52.3% in patients with negative dobutamine results. Causes of mortality were as follows: cardiac 45.4%, cerebrovascular 18.1%, other causes 36.4%. Cardiogical complications were not the cause of death in any of the patients with negative dobutamine results. In dobutamine positive group 62.5% died from cardiological complications. During the 5-year period, cardiac death and manifest coronary disease occurred in 75% of patients with positive dobutamine stress results and only in one patient with negative dobutamine results. Sensitivity was 75%, specificity 89% and positive predictive value 90%. Conclusion. Dobutamine stress echocardiography has a good predictive value for future cardiac events in hemodyalisis patients, and in screening for coronary disease. .

    Distal radial artery pressure (RAP) was observed to be reduced after transradial percutaneous transluminal angioplasty (PTA) on the juxta-anastomotic venous stenosis of radiocephalic arteriovenous fistula (RCAVF). Distal RAPs are easily obtained from a pressure transducer connected with an introducer retrograde inserted into distal radial artery. The clinical role of distal RAP in the setting of transradial PTA remains unknown. This prospective and observational study aimed to explore the relationship between distal RAPs and clinical outcomes. This study recruited hemodialysis patients with RCAVF juxta-anastomotic venous stenosis undergoing transradial PTA. RAP-related variables and procedural data before PTA (pre-PTA) and after PTA (post-PTA) were analyzed. The study endpoint was dysfunction-driven re-PTA during the 1-year follow-up. Overall, 73 PTAs significantly reduced the mean of systolic RAPs from 159.6?±?41.4 to 108.4?±?41.5?mm Hg; P??0.05). The group with angiographically successful PTAs had a significantly lower mean of post-PTA systolic RAPs compared with that with unsuccessful PTAs (98.4?±?35.4 vs. 128.7?±?46.1?mm Hg; P?=?0.003). The post-PTA systolic RAP may be seen as a predictor for 3-month unassisted patency (AUC?=?0.669; P?=?0.048). In conclusion, this study provides the RAP profile to help guide transradial PTA on RCAVF juxta-anastomotic venous stenosis and predict 3-month unassisted patency in a hemodynamic manner.

    Objective: Patients on dialysis have low physical activity levels. The aim of the study was to examine the validity of action planning and coping planning within the theory of planned behaviour framework, for predicting physical activity behaviour of patients on hemodialysis. Methods: One hundred and forty four patients who were undergoing emodialysis were selected from dialysis centers. The mean age of the patients was 56.61 (SD= 11.38) years. The patients completed a questionnaire including variables from the theory of planned behaviour, action planning and coping planning. Physical activity was prospectively assessed at 4-weeks with the validated International Physical Activity Questionnaire self-report measure. A hierarchical regression analysis was performed to examine the effects of action planning and coping planning on physical activity behaviour. Results: There was a main effect for coping planning but not for action planning. Moreover, the analyses resulted in a significant amount of incremental variance accounted for by the interaction of coping planning and intention. Conclusion: Results suggest the combination of high levels of coping planning and intention is associated with increases in physical activity.

Over 2 years, we studied 1,000 patients (average age, 58 years; 50% male; 25% white; 36% diabetic) in three outpatient, staff-assisted hemodialysis units. We used both the eight-scale scores and two-component summary scores to study the relationship between baseline functional health status and clinical outcomes. The physical component summary (PCS) score was as significant a predictor of mortality as was the normalized protein catabolic rate or the delivered Kt/V. Patients with a PCS score below the median for our patients (physically healthier) and a relatively lower MCS score (judged themselves less mentally healthy) than patients who did not skip two or more treatments per month. The prevalence of depression as defined by an MCS score of attendance, and depression. PMID:9261030

    Arteriovenous (AV) grafts are required for hemodialysis access when options for native fistulas have been fully exhausted, where they continue to play an important role in hemodialysis patients, offering a better alternative to central vein catheters. When planning autogenous accesses using Doppler ultrasound, adequate arterial inflow and venous outflow must be consciously preserved for future access creation with grafts. Efforts to improve graft patency include changing graft configuration, graft biology and hemodynamics. Industry offers early cannulation grafts to reduce central catheter use and a bioengineered graft is undergoing clinical studies. Although the outcome of AV grafts is inferior to fistulas, grafts can provide long-term hemodialysis access that is a better alternative to central venous catheters. AV grafts have significant drawbacks, mainly poor patency, infection and cost but also have some advantages: early maturation, ease of creation and needling and widespread availability. The outcome of AV graft surgery is variable from center to center. The primary patency rate for AV grafts is 58% at 6 months and the secondary patency rate is 76% at 6 months and 55% at 18 months. There are centers of excellence that report a 1 year secondary patency rate of up to 91%. In this review of the use of AV grafts for hemodialysis access in the upper extremities, technical issues involved in planning the access and performing the surgery in its different configurations are discussed and the role of surveillance and maintenance with their attendant surgical and radiological interventions is described.

    Continuous ambulatory peritoneal dialysis (CAPD) is a well established method of treating end stage renal failure, and is commonly used as an alternative to hemodialysis. Several complications have been observed. These include catheter malfunction, abdominal and inguinal hernia, and peritonitis. A relatively frequent complication is swelling of external genitalia, due to bowel fluid passing through a patent processus vaginalis. Special diagnostic procedures are necessary to determine the nature of the abnormality and to guide the surgical correction. We reported two cases of patent processus vaginalis in patient on CAPD proved by radionuclide peritonea scintiscan using {sup 99m}Tc-tin colloid.

    Continuous veno-venous hemodialysis using high cutoff filters (HCO-CVVHD) is a promising technique, which may be effective to decrease the extremely high level of circulating myoglobin in patients with rhabdomyolysis (RM). Here, we report a patient with RM caused by heat stroke who was successfully treated by HCO-CVVHD. A male patient received HCO-CVVHD with 4?L/h dialysate for 5 days and then pre-dilution continuous veno-venous hemofiltration (CVVH) at a dose of 4?L/h until recovery of renal function. The clearance of myoglobin and albumin at 5 minutes, and at 4, 12, and 24 hours were calculated. The serum myoglobin level decreased from a peak of 25,400?ng/mL on admission to 133?ng/mL at discharge. During HCO-CVVHD, the mean clearances of serum myoglobin at four timepoints were 61.3 (range, 61.0-61.6), 52.3 (38.9-65.8), 47.3 (46.8-47.9), and 43.7 (39.5-48.0) mL/min, respectively, and the mean clearances of albumin were 12.4 (range, 11.8-13.1), 3.1 (2.5-3.8), 1.2 (1.0-1.4), and 0.8 (0.6-1.0) mL/min, respectively. During CVVH, the clearance rates of myoglobin at 5 minutes and 24 hours were 17.0 and 3.8?mL/min, respectively, with a negligible clearance of albumin. HCO-CVVHD can effectively decrease serum myoglobin in patients with RM because of much higher clearance of myoglobin than CVVH. However, attention should be paid to albumin loss during HCO-CVVHD.

    Fifty patients undergoing colonic surgery received combined thoracic epidural and general anesthesia followed by continuous epidural bupivacaine 0.25% and morphine 0.05 mg/mL, 4 mL/h, for 96 h postoperatively plus oral tenoxicam 20 mg daily. Heart rate (HR) and arterial blood pressure (BP) were measured at supine rest, during orthostatic stress, and after walking prior to and 24, 48, and 72 h and 48 h postoperatively compared to preoperatively (P 0.3; HR, P > 0.34) and 12 vs 8 patient; (P = 0.45) experienced a systolic BP decrease > 20 mm Hg post- versus preoperatively. After walking, systolic BP was significantly lower postoperatively compared with preoperatively (P < or = 0.01). Epidural infusion was discontinued in three patients due to either persisting resting or orthostatic hypotension. There was no correlation between ASA classification, intraoperative bleeding, or postoperative dizziness and incidence of orthostatic hypotension. The results suggest that patients undergoing abdominal surgery and treated with continuous small-dose thoracic epidural bupivacaine-morphine are subjected to a decrease of BP at rest and during mobilization, but not to an extent that seriously impairs ambulation in most patients.

  9. Clinical study of cerebral infarction in hemodialysis patients

    International Nuclear Information System (INIS)

    Stroke is one of the leading causes of death in patients undergoing chronic dialysis. However, few clinical studies have so far examined stroke, especially brain infarction, under such conditions. We retrospectively evaluated the clinical features and risk factors for brain infarction in 33 patients undergoing hemodialysis (hemodialysis, 29 patients; continuous ambulatory peritoneal dialysis, 4 patients; male:female ratio, 25:8) between May 2003 and August 2006. The mean age was 68.5±10.9 (mean±standard deviation (SD)) years. The basal renal diseases were chronic glomerulonephritis (n=16), diabetes mellitus (n=10) and other diseases (n=7). The mean duration of maintenance dialysis before the onset of stroke was 5.6±5.2 years. All 33 patients developed brain infarction, including the atherothrombotic (n=13), lacunar (n=9) and cardioembolic (n=11) types. The complications included a high frequency of hypertension (79%) in all groups, diabetes mellitus (36%) and atrial fibrillation (21%). Four of the patients, 2 with lacunar and 2 with atherothrombotic infarction, developed brain infarction within 3 hours after hemodialysis. Hemodynamic changes might have caused the infarction in these patients. The proportion of patients with a modified Rankin Scale grade of 4-6 at discharge was 42%, and the mortality rate was high (15%). The prognosis of brain infarction was poorer in patients with hemodialysis than in those without. (author)

    1989-01-01

    Aluminum (Al) concentration in serum, urine, and dialysate was estimated in 21 patients undergoing continuous ambulatory peritoneal dialysis (CAPD). In 12 of the patients bone Al concentration was measured as well. Mean serum Al level was 32.4 +/- 21.0 micrograms/l. The Al concentrations in the dialysate and urine were 9.1 +/- 4.1 micrograms/l and 52.5 +/- 47.3 micrograms/l, respectively. Bone Al concentration was 21.0 +/- 14.9 ppm and correlated significantly with concentrations of Al in serum (p less than 0.01) and dialysate (p less than 0.01). A mass transfer (MT) from the patients to the dialysate was observed in all patients (-44.0 +/- 28.8 micrograms/24 h). There was a highly significant correlation between peritoneal Al MT and serum Al (p less than 0.001), actual Al consumption (p less than 0.05) and bone Al concentration (p less than 0.005) supporting the existence of an overflow phenomenon. Despite very low Al levels in the dialysate, patients are at risk of elevated Al levels in the serum, dialysate, urine and bone because of consumption of Al-containing phosphate binders.

    2013-01-01

    Full Text Available Background: Despite recent therapeutic advances, mortality remains high among patients with stage five chronic kidney diseases maintained on hemodialysis (HD. The excess mortality, largely attributable to atherosclerotic cardiovascular disease (ASCVD, remains significant even after controlling for age, diabetes, and hypertension. These factors contributing to the excessive mortality yielding very low survival of patients treated with HD. The first year crude mortality rates among HD patients were 6.6% in Japan, 15.6% in Europe, and 21.7% in the US. Hence US supposed to be the worst in mortality while in Pakistan, such studies were very rare and there is no information regarding HD patients.Methods: Retrospective analysis of 234 patients was performed. Mortality, its patterns and risks were calculated. Patients of end stage renal disease (ESRD maintained on HD for more than three months were included in the study. Index method, log rank test, and cox proportional hazard modeling were applied to analyze the data.Results: Majority of patients were males (mean: 50.7 yrs. Crude death rate of HD patients in the first year was 35% and in 4 year cohort was 40.6%. Mortality was more likely to occur in male as compared to female. Age specific death rate was high in age category 55-64. Age and gender specific death rates were also high in male population. Significant role of conscious level that is, drowsiness and comma were observed yielding high mortality. Patients with drowsy condition show high risk of mortality.Conclusions: The mortality rates of HD patients are high in Pakistan. Patient condition is one of the major factors involved in mortality. Deaths were more likely to occur in males. Serious attention required while dealing HD patients.

    To measure the frequency of depression and its risk factors in patients under going hemodialysis. It is a cross-sectional prospective study conducted at Hemodialysis unit of Shalamar Hospital and Shaikh Zayed Hospital, Lahore from 1/sup st/ January 2006 to 30/sup th/ April 2006. All patients getting regular hemodialysis for more than three months were included. Beck's Depression Inventory- II (BDI-II; adapted in Urdu) was administered on all the patients who were able to read or understand it. Blood sample were drawn at the same time for routine hematological, biochemical parameters and viral markers (Anti HCV and HbsAg). Diagnosis was made as per Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM IV) for correlation of psychological variables with clinical, hematological and biochemical parameters. Eighty nine patients were enrolled which included fifty two (58.4%) were male and seventy seven (86.5%) were married. Major causes of renal failure were diabetes, hypertension and chronic glomerulonephrotis. Duration of dialysis was from 03 to 49 months with mean of 19.64 +- 11.7 months. Severity of depression was categorized in to mild, moderate and severe on the basis of BDI score. Majority of the patients fifty (56.1%) were moderately to severely depressed and there was no gender difference in the prevalence of depression. Majority of patients undergoing hemodialysis were depressed. Major risk factors for depression were marital status, illiterac depression were marital status, illiteracy, number of children, socioeconomic factors, gender, hypertension and hypoalbuminemia. Patients with anemia, hyponatremia and hyperkalemia had suicidal tendency. Patients with hepatitis C and disturbed liver function have strong correlation with psychological parameters. (author)

    Iodine-131 ablation therapy for thyroid cancer in the patient on chronic hemodialysis represents a real problem since the main route of elimination of radioiodine is urinary. There is no recommendation on the management of this treatment in the patient on hemodialysis. We report our experience of management of this treatment in a patient aged 38 years, undergoing hemodialysis for chronic renal failure, and who have been indicated the treatment with iodine-131 for papillary thyroid carcinoma high risk. After multidisciplinary discussions (nephrologists and specialists in nuclear medicine and radiation safety), it has been decided to treat the patient with continuous ambulatory peritoneal dialysis therapy (CAPD). Because of the low but continuous elimination of iodine in the case of CAPD, the patient received a reduced ablative (131)I dose of 1850MBq, which is 30% of the usual dose delivered in subjects with normal renal function. The patient was hospitalized for four days in nuclear medicine unit and the (131)I radioactivity emitted from him was 2.5?Sv/h at one meter at his hospital discharge. In conclusion, CAPD in relay of hemodialysis is a technique of renal replacement therapy that can be suggested to minimize exposure to radioactivity to the patient, his family and the medical staff.

  11. Dialysis-related amyloidosis of the hip joints in long-term hemodialysis patients. MRI findings of hip joints in twelve female hemodialysis patients

    International Nuclear Information System (INIS)

    We report a female with amyloid arthropathy of the hip joints. She was a 67-year-old woman who had been treated by hemodialysis for 22 years. She had demonstrated a 5-month history of continuous low-grade fever and pain in her left hip and she was finally unable to walk by herself. Findings on X-ray films and MRI of the hip joints suggested avascular necrosis in both femur heads. To palliate symptoms, bipolar surgery on the left hip joint was performed. Pathological examination of bone tissue specimen demonstrated that there was some , ?2-microglobulin (?2-MG)-related amyloid accumulation in the femur head. Based on this clinical experience, we performed MRI screening for amyloid lesions of the hip joints in another 11 asymptomatic female patients undergoing hemodialysis for 20 years or more. Cystic lesions of the hip joints were observed in 8 patients, amyloid arthropathy in 2 patients, and fluid trapped in the joint in 1 patient. Patients with amyloidosis had significantly lower serum ?2-MG levels than patients without amyloidosis (28.6 mg/L versus 41.4 mg/L; p=0.0339). Our findings show that dialysis-related amyloidosis of the hip joints is one of the potential and significant problems in female patients on long-term hemodialysis therapy. It may be important to screen for this pathological condition in long-term hemodialysis patients. (author)

  14. Combined peritoneography and computerized tomography for evaluating abdominal complications in patients undergoing continuous peritoneal dialysis

    International Nuclear Information System (INIS)

    Continuous ambulatory peritoneal dialysis (CAPD) is a generally well-tolerated treatment. However, some patients exhibit such complications as to prevent the continuation of treatment. Peritonitis is the major problem, but the continuation of treatment may also be undermined by different complications, such as peritoneal leakage, hernia, catheter malfunctioning, and scrotal-penile edema; a careful investigation of the patient is always needed in such cases. From November 1985 to February 1990, we examined 20 patients, who had presented with different types of complications in the course of dialysis. Peritoneography demonstrated 3 cases of abdominal hernias, 2 cases of patency of the peritoneal-vaginal duct, and 2 cases of catheter obstruction. Peritoneal CT allowed the identification of leakage in 3 patients, while the combined use of the two techniques showed adhesions or pathologic peritoneal recesses in 7 cases. In 3 patients normal patterns were observed. Peritoneography, especially if combined with CT, can carry out a double function, that is in both the screening and choice of the subjects to the destine to peritoneal dialysis, and in therapeutics, to evaluate complications. Moreover, the technique is extremely reliable thanks to both its simple execution and lack of disadvantages

    Full Text Available INTRODUCTION Hemodialysis (HD is one of the most accessible methods for the treatment of the growing number of patients suffering from terminal-stage renal insufficiency. Although headache is the most frequently encountered neurological symptom during HD, there are few studies reporting its prevalence and clinical features. OBJECTIVE The objective of this study was to examine the frequency, demographic and clinical features of headache during HD, and to compare these parameters among patients with and without headache. METHOD The study involved 126 patients (48 female and 78 male with chronic renal failure on regular HD for at least six months, at the Dialysis Unit of Nephrology Department, Kruševac. All patients were inquired about their possible problems with headache using the standardized questionnaire designed according to the diagnostic criteria of the International Headache Classification of Headache Disorders, second edition, published in 2004 (ICHD-II. Subsequently, the patients were clinically evaluated and patients with headaches were further sub classified by a neurologist with special interest in headache disorders. Patients with headache were compared to the patients without headache regarding age, sex, duration of HD, causes of end-stage renal disease, arterial diastolic and systolic blood pressure, and serum values of the most important blood parameters such as sodium, potassium, urea and creatinine. In the group of patients with headache we analyzed the characteristics of specific headache type according to ICHD-II classification. We also analyzed the most important clinical features of hemodialysis headache (HDH. RESULTS In the group of 126 evaluated patients, 41 (32.5% patients had headaches. There were no statistically significant differences between the patients with headaches and those without headaches regarding sex, age, BMI, duration of HD, causes of end-stage renal disease, arterial blood pressure, red blood cell count, serum concentration of hemoglobin, blood urea nitrogen, creatinine, glucose, MCHC, total protein, sodium and potassium. Fourteen patients (34% of those with headaches experienced headache during the HD session and were sub classified as HDH using diagnostic criteria of the International Headache Society. Tension type headache (41% of those with headaches and migraine without aura (10% were most common in the primary headache group and headache due to arterial hypertension (7% was the most prevalent among the secondary headaches. Although there were some common clinical characteristics, we could not find a unifying clinical pattern in the patients with HDH. CONCLUSION Hemodialysis headache is the most common headache in patients undergoing hemodialysis, and despite some common symptoms, it does not appear to be uniform in its clinical characteristics.

    Abstract Background The study aimed to investigate the pharmacokinetics of intravenous ciprofloxacin and the adequacy of 400 mg every 12 hours in critically ill Intensive Care Unit (ICU) patients on continuous veno-venous haemodiafiltration (CVVHDF) with particular reference to the effect of achieved flow rates on drug clearance. Methods This was an open prospective study conducted in the intensive care unit and research unit of a university teaching hospital. The study population was seven critically ill patients with sepsis requiring CVVHDF. Blood and ultrafiltrate samples were collected and assayed for ciprofloxacin by High Performance Liquid Chromatography (HPLC) to calculate the model independent pharmacokinetic parameters; total body clearance (TBC), half-life (t1\\/2) and volume of distribution (Vd). CVVHDF was performed at prescribed dialysate rates of 1 or 2 L\\/hr and ultrafiltration rate of 2 L\\/hr. The blood flow rate was 200 ml\\/min, achieved using a Gambro blood pump and Hospal AN69HF haemofilter. Results Seventeen profiles were obtained. CVVHDF resulted in a median ciprofloxacin t1\\/2 of 13.8 (range 5.15-39.4) hr, median TBC of 9.90 (range 3.10-13.2) L\\/hr, a median Vdss of 125 (range 79.5-554) L, a CVVHDF clearance of 2.47+\\/-0.29 L\\/hr and a clearance of creatinine (Clcr) of 2.66+\\/-0.25 L\\/hr. Thus CVVHDF, at an average flow rate of ~3.5 L\\/hr, was responsible for removing 26% of ciprofloxacin cleared. At the dose rate of 400 mg every 12 hr, the median estimated Cpmax\\/MIC and AUC0-24\\/MIC ratios were 10.3 and 161 respectively (for a MIC of 0.5 mg\\/L) and exceed the proposed criteria of >10 for Cpmax\\/MIC and > 100 for AUC0-24\\/MIC. There was a suggestion towards increased ciprofloxacin clearance by CVVHDF with increasing effluent flow rate. Conclusions Given the growing microbial resistance to ciprofloxacin our results suggest that a dose rate of 400 mg every 12 hr, may be necessary to achieve the desired pharmacokinetic - pharmacodynamic (PK-PD) goals in patients on CVVHDF, however an extended interval may be required if there is concomitant hepatic impairment. A correlation between ciprofloxacin clearance due to CVVHDF and creatinine clearance by the filter was observed (r2 = 0.76), providing a useful clinical surrogate marker for ciprofloxacin clearance within the range studied.

    Full Text Available Background/Aim. Hemodialysis (HD is a therapeutic procedure used to partially correct homeostatic disorders and prevent complications of uremia to appear in the terminal stage of renal insufficiency. The aim of this study was to evaluate and analyze the incidence and features of headaches in patients undergoing hemodialysis. Methods. A total of 143 patients, 50 women and 93 men, undergoing hemodialysis, were questioned about their problems with headache using a questionnaire designed according to the diagnostic criteria of the International Headache Classification of Headache Disorders from 2004. The patients were separated into two groups: the patients without headache and the patients with repeated headaches. Afterwards, the patients with headaches were further divided into subgroups: the patients who had the headaches before the beginning of HD and patients who experienced repeated headaches with the beginning of HD headache (HDH. In the group of patients with headaches we analyzed characteristics of headache according to which diagnoses of headaches were made, as well as the effects of HD on headaches. We also analyzed features of HDH. The patients with headache were compared to the patients without headache regarding sex, age, duration of HD, causes of end-stage renal disease, arterial diastolic and systolic blood pressure and serum concentration of hemoglobin, urea nitrogen, creatinine, sodium and potassium. The results were statistically compared. Results. In the group of 143 patients examined, 27 (18.9% patients had headaches. There were no statistically significant differences between the group of patients with headaches and those without headache regarding to sex, age, duration of HD, causes of end-stage renal disease, serum concentration of hemoglobin, urea nitrogen, creatinine, sodium and potassium. The patients with headaches showed significantly higher mean values of systolic blood pressure during HD in comparison to the patients without headaches (p = 0.029. There was no statistically significant difference between the two groups regarding the mean values of diastolic blood pressure. Nineteen (13.3% patients had had headache before starting HD. HD did not have any effect on the characteristics of headaches in more than a half of these patients. In 8 (5.6% patients we diagnosed HDH using the diagnostic criteria of the International Headache Classification of Headache Disorders from 2004. HDH showed similar characteristics in all the patients: it appeared mostly in men, during the 4th hour of HD, lasted less than four hours, it was localized bilaterally in the frontal parts of the head, strong in intensity, throbbing and without the associated symptoms. Conclusion. The results of our study clearly showed that HDH was a particular entity of headache, not only because of its connection with HD, but because it had similar characteristics in all the patients in which it had appeared. Finding out the pathophysiological mechanisms of their occurrence would significantly improve the quality of life style of patients on hemodialysis. .

  10. Optimal nutrition in hemodialysis patients.

    2013-03-01

    Protein-energy wasting (PEW) is highly prevalent in patients undergoing maintenance hemodialysis (MHD). It is important to note that there is a robust association between the extent of PEW and the risk of hospitalization and death in these patients, regardless of the nutritional marker used. The multiple etiologies of PEW in advanced kidney disease are still being elucidated. Apart from the multiple mechanisms that might lead to PEW, it appears that the common pathway for all of the derangements is related to exaggerated protein degradation along with decreased protein synthesis. The hemodialysis procedure per se is an important contributor to this process. Metabolic and hormonal derangements such as acidosis, inflammation, and resistance to anabolic properties of insulin resistance and growth hormone are all implicated for the development of PEW in MHD patients. Appropriate management of MHD patients at risk for PEW requires a comprehensive combination of strategies to diminish protein and energy depletion and to institute therapies that will avoid further losses. The mainstay of nutritional treatment in MHD patients is provision of an adequate amount of protein and energy, using oral supplementation as needed. Intradialytic parenteral nutrition should be attempted in patients who cannot efficiently use the gastrointestinal tract. Other anabolic strategies such as exercise, anabolic hormones, anti-inflammatory therapies, and appetite stimulants can be considered as complementary therapies in suitable patients. PMID:23439378

  11. Destructive spondyloarthropathy in hemodialysis patients

    International Nuclear Information System (INIS)

    Destructive spondyloarthropathy (DSA) has been observed in patients undergoing long-term hemodialysis. The pathophysiology of this condition is still unknown, but there is evidence that amyloid depositions play an important role in its development. Despite several reports, the radiological evolution of these lesions is poorly known. The authors report the results of the radiographic follow-up (12-18 months) of 9 cases (7 female and 2 male patients; age 63±6 years) hemodilized for over 60 months (mean: 126±33). In 7 cases. radiographic patterns of destructive arthropathy were seen in peripheral joints as well. X-ray pictures demonstrated: 1) increased erosion of vertebral end plates (in all cases); 2) increased narrowing of invertebral spaces (in 5 cases); 3) increased collapse of vertebral bodies (in 5 cases); 4) increased malalignment of the involved segments (in 4 cases). In 3 autopsied cases ?2-microglobulin amyloid depositions were found in disc and ligamentous paravertebral tissue. These results confirm that: 1) DSA is progressive in longterm hemodialysis patients; 2) radiographic evolution is often very quick; 3) the cervical spine is the most frequently involved location and the one where lesions are quickest to develop; 4) severe malalignament of the involved spine may be present, with subsequent neurological complications

  13. Destructive spondyloarthropathy in hemodialysis patients

    International Nuclear Information System (INIS)

    A destructive spondyloarthropathy is reported in four patients undergoing maintenance hemodialysis for chronic renal disease. In a separate investigation a controlled, prospective radiographic study of the cervical spine revealed this spondyloarthropathy in 4 (15%) of 26 long-term dialysis patients. A single disk level was involved in three patients, and two disc levels were involved in one patient. This spondyloarthropathy correlated with the duration of dialysis but not with the radiographic evidence of renal osteodystrophy or severity of laboratory abnormalities associated with hyperparathyroidism. Three of these four patients also had discovertebral erosions or destruction involving the lumbar spine. Cervical spine flexion views revealed evidence of ligamentous laxity or instability in three (12%) dialysis patients, all with vertebral resorption and disc space narrowing. It is postulated that this instability may contribute to the development of cervical discovertebral lesions or be a secondary manifestation of disc destruction. (orig.)

    Full Text Available Abstract Background Low bone mass is common in end-stage renal disease patients, especially those undergoing hemodialysis. It can lead to serious bone health problems such as fragility fractures. The purpose of this study is to investigate the risk factors of low bone mass in the hemodialysis patients. Methods Sixty-three subjects on hemodialysis for at least 6 months were recruited from a single center for this cross-sectional study. We collected data by questionnaire survey and medical records review. All subjects underwent a bone mineral density (BMD assay with dual-energy x-ray absorptiometry at the lumbar spine and right hip. Data were statistically analyzed by means of descriptive analysis, independent t test and one way analysis of variance for continuous variables, Pearson product-moment correlation to explore the correlated factors of BMD, and stepwise multiple linear regression to identify the predictors of low bone mass. Results Using WHO criteria as a cutoff point, fifty-one subjects (81% had a T-score lower than -1, of them 8 subjects (13% had osteoporosis with the femoral neck most commonly affected. Regarding risk factors, age, serum alkaline phosphatase (ALP level, and intact parathyroid hormone (iPTH level had significant negative correlations with the femoral neck and lumbar spine BMD. On the other hand, serum albumin level, effective exercise time, and body weight (BW had significant positive correlations with the femoral neck and lumbar spine BMD. Age, effective exercise time, and serum albumin level significantly predicted the femoral neck BMD (R2 × 0.25, whereas BW and the ALP level significantly predicted the lumbar spine BMD (R2 × 0.20. Conclusion This study showed that advanced age, low BW, low serum albumin level, and high ALP and iPTH levels were associated with a low bone mass in the hemodialysis patients. We suggest that regular monitoring of the femoral neck BMD, maintaining an adequate serum albumin level and BW, and undertaking an exercise program are important to improve bone health in the patients undergoing hemodialysis.

    2014-07-01

    Continuous renal replacement therapy (CRRT) is a therapeutic technique used to support critically ill patients with acute renal failure in intensive care units. CRRT is preferred over hemodialysis for patients who cannot tolerate the rapid fluid and electrolyte shifts associated with hemodialysis because of their tenuous hemodynamic state. Traditionally, such patients have not been candidates for mobilization and have remained on strict bed rest. Mobilization is now being initiated on patients undergoing CRRT in intensive care units. This case study chronicles the successful mobilization of a patient undergoing CRRT. This experience suggests that CRRT patients who are appropriate candidates may be mobilized safely and therefore should not automatically be excluded from mobilization therapies. PMID:24986178

    This paper proposes a novel model-based control methodology for a computer-controlled hemodialysis system, designed to maintain the hemodynamic stability of end-stage renal failure patients undergoing fluid removal during hemodialysis. The first objective of this paper is to introduce a linear parameter varying system to model the hemodynamic response of patients during hemodialysis. Ultrafiltration rate (UFR) and dialysate sodium concentration (DSC) are imposed as the inputs, and the model computes the relative blood volume (RBV), percentage change in heart rate ( ?HR), and systolic blood pressure (SBP) during the course of hemodialysis. The model parameters were estimated based on data collected from 12 patients undergoing 4 profiled hemodialysis sessions. The modeling results demonstrated that the proposed model could be useful for estimating the individual patient's hemodynamic behavior during hemodialysis. Based on the model, the second objective is to implement a computer-controlled hemodialysis system for the regulation of RBV and HR during hemodialysis while maintaining SBP within stable range. The proposed controller is based on a model predictive control approach utilizing pre-defined constraints on the control inputs (UFR and DSC) as well as the output (SBP). The designed control system was experimentally verified on four patients. The results demonstrated that the proposed computer-controlled hemodialysis system regulated the RBV and HR of the patients according to individual reference profiles with an average mean square error of 0.24% and 2.6%, respectively, and thus can be potentially useful for ensuring the stability of patients undergoing hemodialysis by avoiding sudden changes in hemodynamic variables.

    This report seeks to describe the clinical efficacy and safety of infliximab in a patient with psoriatic arthritis on hemodialysis and to review the literature on the topic. We present a patient with psoriatic arthritis on hemodialysis treated with infliximab and we review the literature. Our case includes a patient with severe psoriasis and dactylitis with chronic renal failure requiring regular hemodialysis. At presentation the patient had a psoriasis area and severity index (PASI) score of 35.1 and dactylitis affecting the right thumb. Evaluation of laboratory parameters revealed a slight increase of erythrocyte sedimentation rate (21 mm/h) and a mild normocytic anemia (Hct 36.4). The rest of the laboratory and imaging tests were within normal limits. Infliximab was initiated at the loading dose of 5 mg/kg body weight at weeks 0, 2, 6, and every 8 weeks thereafter. On retreatment at week 14 the PASI score was measured to 3.4. After the conclusion of 6 months of treatment, the reduction of PASI score was sustained reaching the point of 0.8. In addition, dactylitis, as well as laboratory parameters, showed a striking improvement. On the other hand, during the same period of time, no changes of renal functions were noted and no complications were reported and the patient continued his hemodialysis on a regular basis. Our case is in accordance with other reports supporting that infliximab treatment in patients undergoing hemodialysis can be safe, well tolerated, and effective. However, larger trials are needed to prove its use in these patients. PMID:20490588

    Full Text Available In this report, we present a pediatric case of severe symptomatic hypermagnesemia resulting from the use of magnesium oxide as a laxative in a child undergoing continuous cyclic peritoneal dialysis for end-stage renal disease. The patient showed abnormal electrocardiography (ECG findings, such as tall T waves, a widened QRS complex, and irregular conduction, which were initially misdiagnosed as hyperkalemia; later, the correct diagnosis of hypermagnesemia was obtained. Emergent hemodialysis successfully returned the serum magnesium concentration to normal without complications. When abnormal ECG changes are detected in patients with renal failure, hypermagnesemia should be considered.

    Dialysis procedures are life-sustaining renal replacement therapies indicated for patients with limited or no kidney function. The formation of clots in the extracorporeal circuit during dialysis is an undesirable event. Anticoagulation is therefore routinely practiced in this context. Unfractionated heparin (UFH) is largely used in dialysis patients. However, except in patients with an elevated risk of bleeding, the 2002 European Best Practice Guidelines Expert Group on Hemodialysis recommended the use of low-molecular-weight heparins over UFH, in view of their equal efficacy, improved safety, and easy handling. Low-molecular-weight heparins comprise several drugs, differing in a number of pharmacological and clinical properties. This manuscript reviews the data obtained with nadroparin, a low-molecular-weight heparin studied extensively in dialysis patients. Thus, several studies investigated the benefit of nadroparin vs. UFH, other low-molecular-weight heparins, or citrate in patients undergoing intermittent hemodialysis. Overall, they showed that a single intravenous bolus dose of nadroparin, adjusted according to body weight, was effective and safe for maintaining the patency of the extracorporeal circuit during intermittent hemodialysis sessions lasting up to 6 hours, in both adults and children with end-stage renal failure. In contrast to UFH, nadroparin required no laboratory monitoring of anticoagulant activity owing to the reliable anticoagulant response following its administration. Compared with UFH, nadroparin was beneficial in terms of lipid and possibly bone parameters. Nadroparin administered by a bolus dose, followed by a continuous infusion was also shown to be effective and safe in patients undergoing continuous renal replacement therapy for acute renal failure.

    Full Text Available Objective: Low bone mass in end-stage renal disease patients, especially those undergoing hemodialysis, can lead to serious health problems such as fragility fractures and may have negative impact on their quality of life. The aim of this study was to determine bone mineral density (BMD in a group of hemodialysis patients and to evaluate its relationship with several clinical parameters and markers of biochemical bone turnover.Materials and Methods: Thirty hemodialysis patients, with a mean age of 49.7±16.0 years, were included in the study. The BMD was measured at the lumbar spine (L2-L4 and at the proximal femur by dual-energy X-ray absorptiometry (DXA. Markers of biochemical bone turnover such as calcium, phosphorus, alkaline phosphatase, intact parathyroid hormone (iPTH, plasma bicarbonate, blood pH, serum albumin, and hematocrit levels were measured before the hemodialysis session. Results: The mean T-scores at lumbar spine and femur neck were -1.6±0.8 and -2.6±1.1, respectively. According to the World Health Organization criteria based on BMD T-score at lumbar spine, 7% of patients were osteoporotic, 60% osteopenic, and 33% normal. On the other hand, at femur neck, the results were 50% osteoporotic, 40% osteopenic, and 10% normal. No significant differences were observed in age, duration of hemodialysis and iPTH levels between the patients with or without osteoporosis at femur neck. No correlation was found between BMD at both sites and age, duration of hemodialysis, serum calcium, phosphorus, alkaline phosphatase and iPTH levels. There were no statistically significant differences in BMD and biochemical markers of bone turnover between sexes. Conclusion: In this study, we showed that 53% of the patients undergoing hemodialysis have osteoporosis, especially at femur neck. Thus, we suggest regular monitoring of the femur neck BMD in order to improve bone health of the chronic hemodialysis patients. Turk J Phys Med Rehab 2010;56:62-6.

  14. Hepatitis C virus screening and management of seroconversions in hemodialysis facilities.

    Over the past two decades, healthcare-associated exposure has increasingly been proved to be a means of hepatitis C virus (HCV) transmission, especially in hemodialysis facilities. The prevalence of HCV among hemodialysis patients is known to be several times greater than that of the general population of the United States, and chronic HCV infection is associated with significant morbidity and mortality among these patients. During 2008-2011, HCV infection outbreaks were identified in multiple US hemodialysis facilities, resulting in at least 46 new HCV infections among hemodialysis patients. These outbreaks, linked to infection control breaches, also highlight the failure of some facilities to follow established guidelines for routine HCV antibody (anti-HCV) screening and response to new HCV infection among hemodialysis patients. Current national guidelines recommend screening of hemodialysis patients for anti-HCV on facility admission and, for susceptible patients, on a semiannual basis. Here, we seek to underscore the importance of compliance with national recommendations for anti-HCV screening of hemodialysis patients and actions to be taken in the event of possible HCV transmission within a hemodialysis facility. These include general steps to ensure that: hemodialysis patients are routinely screened for anti-HCV to facilitate early detection of new infections; newly infected patients are informed of the change in their HCV status and undergo clinical evaluation; and public health officials are notified of new HCV infections in a timely manner. We then focus on the need to assess infection control practices at the facility, with particular attention given to safe handling of injectable medications, hand hygiene and disinfection practices. In the absence of a vaccine, routine screening and adherence to standard infection control practices will remain the key strategies for preventing HCV transmission in hemodialysis units.

    Full Text Available The aim of this study was to examine racial differences in long-term survival among hemodialysis patients after coronary artery bypass grafting (CABG. To our knowledge this has not been previously addressed in the literature. Black and white hemodialysis patients undergoing first-time, isolated CABG procedures between 1992 and 2011 were compared. Survival probabilities were computed using the Kaplan-Meier product-limit method and stratified by race. Hazard ratios (HR and 95% confidence intervals (CI were computed using a Cox regression model. A total of 207 (2% patients were on hemodialysis at the time of CABG. White (n = 80 hemodialysis patients had significantly decreased 5-year survival compared with black (n = 127 patients (adjusted HR = 1.9, 95% CI = 1.2–2.8. Our finding provides useful outcome information for surgeons, primary care providers, and their patients.

    Carboplatin is one of the most prescribed cytotoxic drug, which is extensively used in the treatment regimens of several malignancies. The therapeutic efficiency of carboplatin has been found to correlate the area under curve (AUC). The Calvert formula has been extensively used to determine the dose of carboplatin for a fixed AUC and glomerular filtration rate (GFR). This formula has also been used in patients with end-stage renal disease on hemodialysis by assuming that the GFR is zero. This is applicable to patients who receive hemodialysis within 12-18 h after carboplatin infusion. After the first 24 h, a majority of the carboplatin is bound to proteins is not easily dialyzable and hence continues to remain in the blood stream despite repeated sessions of hemodialysis. We derive a correction factor to calculate the resultant AUC in such patients. The analysis done by using this correction factor shows that the AUC can increase by eightfold in patients who received the adjusted dose but whose hemodialysis was delayed beyond 24 h after infusion. The correction factor proposed here can also be used to calculate the dose adjustment required a priori in patients who may receive delayed hemodialysis. It is also useful to predict the AUC and estimate the resultant toxicity in such patients. PMID:24452283

    Full Text Available Abstract Background The influence of serum leptin levels on nutritional status and survival in chronic hemodialysis patients remained to be elucidated. We conducted a prospective longitudinal study of leptin levels and nutritional parameters to determine whether changes of serum leptin levels modify nutritional status and survival in a cohort of prevalent hemodialysis patients. Methods Leptin, dietary energy and protein intake, biochemical markers of nutrition and body composition (anthropometry and bioimpedance analysis were measured at baseline and at 6, 12, 18 and 24 months following enrollment, in 101 prevalent hemodialysis patients (37% women with a mean age of 64.6 ± 11.5 years. Observation of this cohort was continued over 2 additional years. Changes in repeated measures were evaluated, with adjustment for baseline differences in demographic and clinical parameters. Results Significant reduction of leptin levels with time were observed (linear estimate: -2.5010 ± 0.57 ng/ml/2y; p Conclusions Thus leptin levels reflect fat mass depots, rather than independently contributing to uremic anorexia or modifying nutritional status and/or survival in chronic hemodialysis patients. The importance of such information is high if leptin is contemplated as a potential therapeutic target in hemodialysis patients.

    Full Text Available Pulmonary hypertension (PH has been described in patients undergoing hemodialysis and proposed to arise from overflow in arterio-venous grafts or fistulae. Whether PH is prevalent in patients undergoing catheter-based dialysis is unknown. Patients undergoing hemodialysis with an echocardiogram in two urban dialysis centers over a four-year period were included. Demographic data, comorbidities, dialysis access, laboratory and echocardiographic data were collected. A right ventricular systolic pressure of ?45 mmHg defined PH. Forty out of ninety-one (44% patients met the criteria for PH. The prevalence of catheter-based hemodialysis was similar in the two groups (30% in the PH vs. 33% in the no-PH group. PH patients were more likely to have extended hemodialysis vintage (52.6±58.2 vs. 31.0±33.7 months, P less than 0.05. Advanced left heart disease was not more prevalent in patients with PH although they were more likely to have right atrial and right ventricular enlargement (P less than 0.05. Mean serum phosphate was lower in the PH group (4.7±1.4 vs. 5.5±1.8 mg/dL, P less than 0.05. On multivariate analysis, lower phosphate levels were associated with higher risk of PH. We concluded that PH is prevalent in hemodialysis regardless of access type and may be because of disordered calcium and phosphate metabolism.

    As the dialysis population ages, their limitations in performing daily activities affect the well-being of the patients as well as increase the burden on caregivers and the use of health services. In this cross-sectional study, we measured the proportion of patients 65 years and older undergoing chronic outpatient hemodialysis who needed help with day-to-day activities and identified the clinical characteristics of this population at most risk. Their dependence in performance of basic self-care tasks and instrumental activities such as driving were measured by the Barthel and Lawton Scales. Associations between disability in four basic activities to age, gender, education, multiple prescription drug needs, diabetes, cognition, depressive symptoms, and physical performance were examined using logistic regression. Of the 162 mostly male participants averaging 75 years old, eight had no disability, 69 had only instrumental dependence, and 85 had combined disability. Multiple prescription drug needs, poor timing in 'up-and-go' mobility performance, and education level were associated with basic dependency. Our study shows that the disability in self-care is common among older patients on hemodialysis. Strategies are needed to routinely identify those older dialysis patients at risk of functional impairment and to limit their disabilities. PMID:18354381

    Preemptive renal transplantation is the method of choice for end stage renal disease in childhood and adolescence. However, without preemptive transplantation, waiting time for kidney transplantation might exceed several years. The poor quality of life and the extremely high morbidity and mortality rates of dialysis patients have led to the development of intensified hemodialysis programs in which the modes of dialysis (short daily, nocturnal intermittent or daily nocturnal) are different. Such programs have been shown to significantly improve several uremia-associated parameters, such as blood pressure, phosphate control, anemia and growth retardation, in both adult and pediatric (children and adolescents) patients and lead to a reduction in medications, including phosphate binders, erythropoietin and antihypertensive agents. Fluid limitations and dietary restrictions can also be lifted. With respect to psychosocial rehabilitation and quality of life, nocturnal intermittent dialysis programs provide a reasonable compromise of all forms of intensified programs. Experiences and practical approaches of our own in-center nocturnal intermittent hemodialysis program in the light of the recent publications are described in this review. PMID:25103600

    Anxiety, depression and suicidal thoughts are highly prevalent comorbidities of end-stage-renal-disease (ESRD). There are no studies in Lebanon on the prevalence of these symptoms in Lebanese end-stage-renal-disease patients. Moreover, the association between ESRD on one hand, and anxiety, depression and suicidal ideation on the other has never been established in Lebanon. Groups of patients at a high-risk of development of these symptoms are not determined. The Hospital Anxiety and Depression Score and M.I.N.I (module C) were used to measure the prevalence of anxiety, depression and suicidal ideation in 51 patients from the dialysis center of Hotel-Dieu de France Hospital in Lebanon. In our sample, 45% of included patients suffered from symptoms of anxiety and 50% presented symptoms of depression.The prevalence of suicidal ideation as detected by the M.I.N.I. is at 37%. No patients presented with a high risk of suicide. There was a statistically significant correlation between the existence of organic comorbidities and the presence of symptoms of depression and suicidal ideation. As for anxiety, the association was marginally significant. The results obtained by our study are consistent with those found in studies performed in other societies. The profile of depression- and suicidal ideation-prone patients has been determined. It consists of patients with at least one medical comorbidity to the ESRD. This, in turn, should lead to increased awareness and better treatment of these psychiatric ailments, considering their impact on morbidity and mortality in ESRD. PMID:24337520

    End-stage renal disease (ESRD) is an irreversible and life-threatening condition. In Jordan, the number of ESRD patients treated with hemodialysis is on the rise. Identifying stressors and coping strategies used by patients with ESRD may help nurses and health care providers to gain a clearer understanding of the condition of these patients and thus institute effective care planning. The purpose of this study was to identify stressors perceived by Jordanian patients on hemodialysis, and the coping strategies used by them. A convenience sample of 131 Jordanian men and women was recruited from outpatients' dialysis units in four hospitals. Stressors perceived by participants on hemodialysis and the coping strategies were measured using Hemodialysis Stressor Scale, and Ways of Coping Scale-Revised. Findings showed that patients on hemodialysis psychosocial stressors scores mean was higher than the physiological stressors mean. Positive reappraisal coping strategy had the highest mean among the coping strategies and the lowest mean was accepting responsibility. Attention should be focused towards the psychosocial stressors of patients on hemodialysis and also helping patients utilize the coping strategies that help to alleviate the stressors. The most used coping strategy was positive reappraisal strategy which includes faith and prayer. PMID:25158058

    Doripenem is a novel wide-spectrum antibiotic, and a derivate of carbapenems. It is an ideal antibiotic for treatment of serious nosocomial infections and severe sepsis for its exceptionally high efficiency and broad antibacterial spectrum of action. Doripenem is eliminated mainly by the kidneys. In cases of acute kidney injury, dosing of doripenem depends on creatinine clearance and requires adjustments. Doripenem is eliminated during hemodialysis because its molecular weight is 300–400 Da. The aim of this study was to establish the impact of continuous renal replacement therapy (CRRT) slow low-efficiency dialysis (SLED) on doripenem serum concentrations in a population of intensive-therapy patients with life-threatening infections and severe sepsis. Ten patients were enrolled in this observational study. Twelve blood samples were collected during the first administration of doripenem in a 1-hour continuous infusion while CRRT SLED was provided. Fluid chromatography was used for measurement of the concentration of doripenem in serum. In all collected samples, concentration of doripenem was above the minimum inhibition concentration of this antibiotic. Based on these results, we can draw the conclusion that doripenem concentration is above the minimum inhibition concentration throughout all of CRRT. The dosing pattern proposed by the manufacturer can be used in patients receiving CRRT SLED without necessary modifications. PMID:25364230

    Full Text Available Abstract Background Over 290,000 patients are undergoing hemodialysis (HD in Japan. With old age, the odds of undergoing HD treatment sharply increase, as does the prevalence of cognitive impairment. The aim of the present work was to assess cognitive impairment in HD patients and its relation to clinical characteristics. Methods Using a cross-sectional design, we administered the Mini-Mental State Examination (MMSE to 154 HD outpatients and 852 participants from the Iwaki Health Promotion Project 2010, representing the general population. Results The prevalence of cognitive impairment based on the MMSE was 18.8% in HD patients. HD patients showed a higher prevalence of cognitive impairment in older groups (50 years and older. In a logistic regression model with age, gender and amount of education as covariates, undergoing HD was a significant independent factor (OR = 2.28, 95% CI 1.33 to 3.94 associated with a lower MMSE score. Among HD patients, we found that level of education was associated with MMSE score. Conclusions There is a high prevalence of cognitive impairment among HD patients that has adverse implications for hospitalization and shortens their life expectancy. HD treatment was an independent risk factor for cognitive impairment. Clinicians should carefully monitor and treat cognitive impairment in HD patients. Further studies are required to determine the reasons for cognitive impairment in HD patients.

    Studies of outcomes associated with dialysis therapies have yielded conflicting results. Bloembergen et al showed that prevalent patients on continuous ambulatory peritoneal dialysis (CAPD) or continuous cycling peritoneal dialysis (CCPD) had a 19% higher mortality risk than hemodialysis patients, and Fenton et al, analyzing Canadian incident patients, found a 27% lower risk. Attempting to reconcile these differences, we evaluated incident Medicare patients (99,048 on hemodialysis, 18,110 on CAPD/CCPD) from 1994 through 1996, following up to June 30, 1997. Patients were followed to transplantation, death, loss to follow-up, 60 days after modality change, or end of the study period. For each 3-month survival period, we used an interval Poisson regression to compare death rates, adjusting for age, gender, race, and primary renal diagnosis. A Cox regression was used to evaluate cause-specific mortality, and proportionality was addressed in both regressions by separating diabetic and nondiabetic patients. The Poisson regressions showed CAPD/CCPD to have outcomes comparable with or significantly better than hemodialysis, although results varied over time. The Cox regression found a lower mortality risk in nondiabetic CAPD/CCPD patients (women younger than 55 years: risk ratio [RR] = 0. 61; Cl, 0.59 to 0.66; women age 55 years or older: RR = 0.87; Cl, 0. 84 to 0.91; men younger than 55 years: RR = 0.72; Cl, 0.67 to 0.77; men age 55 years or older: RR = 0.87; Cl, 0.83 to 0.92) and in diabetic CAPD/CCPD patients younger than 55 (women: RR = 0.88; Cl, 0. 82 to 0.94; men: RR = 0.86; Cl, 0.81 to 0.92). The risk of all-cause death for female diabetics 55 years of age and older, in contrast, was 1.21 (Cl, 1.17 to 1.24) for CAPD/CCPD, and in cause-specific analyses, these patients had a significantly higher risk of infectious death. We conclude that, overall, within the first 2 years of therapy, short-term CAPD/CCPD appears to be associated with superior outcomes compared with hemodialysis. It also appears that patients on the two therapies have different mortality patterns over time, a nonproportionality that makes survival analyses vulnerable to the length of follow-up. Further investigation is needed to evaluate both the potential explanations for these findings and the use of more advanced statistical methods in the analysis of mortality rates associated with these dialytic therapies.

    Full Text Available On-line monitoring devices to control functions such as volume, body temperature, and ultrafiltration, were considered more toys than real tools for routine clinical application. However, bio-feedback blood volume controlled hemodialysis (HD is now possible in routine dialysis, allowing the delivery of a more physiologically acceptable treatment. This system has proved to reduce the incidence of intra-HD hypotension episodes significantly. Ionic dialysance and the patient?s plasma conductivity can be calculated easily from on-line measurements at two different steps of dialysate conductivity. A bio-feedback system has been devised to calculate the patient?s plasma conductivity and modulate the conductivity of the dialysate continuously in order to achieve a desired end-dialysis patient plasma conductivity corresponding to a desired end-dialysis plasma sodium concentration. Another bio-feedback system can control the body tempe-rature by measuring it at the arterial and venous lines of the extra-corporeal circuit, and then modulating the dialysate temperature in order to stabilize the patients? temperature at constant values that result in improved intra-HD cardiovascular stability. The module can also be used to quantify vascular access recirculation. Finally, the simultaneous computer control of ultrafiltration has proven the most effective means for automatic blood pressure stabilization during hemo-dialysis treatment. The application of fuzzy logic in the blood-pressure-guided biofeedback con-trol of ultrafiltration during hemodialysis is able to minimize HD-induced hypotension. In con-clusion, online monitoring and adaptive control of the patient during the dialysis session using the bio-feedback systems is expected to render the process of renal replacement therapy more physiological and less eventful.

  18. The strategy of performing non-prophylactic hemodialysis therapy after administration of contrast media in renal insufficiency patients

    International Nuclear Information System (INIS)

    Acute renal failure induced by contrast media is an important problem in renal insufficiency patients. Prophylactic hemodialysis is usually undertaken after the administration of radiocontrast media. However, we decided to cease giving prophylactic hemodialysis from February, 2002 in line with the guidelines regarding dialysis and contrast media administration provided by the European Society of Urogenital Radiology. We reported our policy at the doctor's meeting of hemodialysis therapy and at the meeting of clinical engineering technologists which were held in Okinawa. After the presentation, a questionnaire survey in 28 hospitals was undertaken by telephone. In all the hospitals, prophylactic hemodialysis after the administration of radiocontrast media was still being continued, with the exception of one hospital. We need to enlighten medical staff that the strategy of performing hemodialysis immediately after the administration of contrast media in patients with reduced renal function does not diminish the rate of radiocontrast media-induced nephropathy.

    We report a 68-year-old Japanese man with end-stage renal failure requiring hemodialysis and chronic disseminated intravascular coagulation (DIC) related to thrombosis in an aortic aneurysm. He had undergone graft replacement for the dissection of the ascending and descending thoracic aorta in 1990 and 2002, respectively. Computed tomography disclosed an aneurysm with thrombosis in the residual aorta adjacent to the graft anastomosis. DIC was diagnosed based on elevation of serum fibrinogen degradation products while his activated partial thromboplastin time, prothrombin time and fibrinogen level were normal. In 2008, hemodialysis was initiated for end-stage renal failure. Dialysis was performed without administration of an anticoagulant because his activated clotting time (ACT) was prolonged to 150–180 s. Thereafter, stable hemodialysis continued without clotting in the dialysis circuit until 2013. If monitoring of ACT can be done, hemodialysis without anticoagulation may be a therapeutic option in such patients. PMID:24707280

    Full Text Available Home hemodialysis (HHD has proved to be a useful form of renal replacement therapy. The economic advantage of HHD is well established and interest in it is renewed. Once it has been decided to establish a HHD program, a well developed strategic plan is required. This should address financial and logistical issues and establish policies that will address responsi-bilities of both patients and HD centers. The recruitment of patients is facilitated by ensuring that all incident patients have early access to an education program describing all forms of renal replacement therapy that the regional renal program provides. Patients and members of the pre-dialysis education program should understand the selection process criteria in advance. Once the assessment is completed and the patient agrees to the proceedings, a plan of action should be esta-blished for enrolling the patient into the program and initiating training. Patients? education pro-gram should take into consideration principles of adult learning. When choosing dialysis equip-ment for home use, the needs and preferences of the patients should be respected. As a rule of thumb, the equipment should be simple to use, yet still provide adequate and reliable therapy. De-ciding where to set up and position the HHD equipment is important. Installation of HHD ma-chine at home requires a continuous supply of accessories. Before establishing a HHD program, commitment of the dialysis center to provide and maintain the infrastructure of the program is mandatory. The estimated patients suitable for HHD are less than 15% of all prospective dialysis patients. Generally, those who are have greatly improved quality of life and by using modalities such as nocturnal and daily dialysis can have improved physical well-being with considerable potential cost savings.

    Liver transplantation (LT) for patients with renal dysfunction is frequently complicated by major fluid shifts, acidosis, and electrolyte and coagulation abnormalities. Continuous renal replacement therapy (CRRT) has been previously shown to ameliorate these problems. We describe the safety and clinical outcomes of intraoperative hemodialysis (IOHD) during LT for a group of patients with high Model for End-Stage Liver Disease (MELD) scores. We performed a retrospective study at our institution of patients who underwent IOHD from 2002 to 2012. Seven hundred thirty-seven patients underwent transplantation, and 32% received IOHD. The mean calculated MELD score was 37, with 38% having a MELD score???40. Preoperatively, 61% were in the intensive care unit, 19% were mechanically ventilated, 43% required vasopressor support, and 80% were on some form of renal replacement therapy at the time of transplantation, the majority being on CRRT. Patients on average received 35 U of blood products and 4.8 L of crystalloids without significant changes in hemodynamics or electrolytes. The average urine output was 450 ml, and the average amount of fluid removal with dialysis was 1.8 L. The 90-day patient and dialysis-free survival rates were 90% and 99%, respectively. One-year patient survival rates based on the pretransplant renal replacement status and the MELD status were not statistically different. This is the first large study to demonstrate the safety and feasibility of IOHD in a cohort of critically ill patients with high MELD scores undergoing LT with good patient and renal outcomes.

    Full Text Available Abstract Aim High prevalence of Hepatitis C virus (HCV has been reported among the dialysis patients throughout the world. No serious efforts were taken to investigate HCV in patients undergoing hemodialysis (HD treatment who are at great increased risk to HCV. HCV genotypes are important in the study of epidemiology, pathogenesis and reaction to antiviral therapy. This study was performed to investigate the prevalence of active HCV infection, HCV genotypes and to assess risk factors associated with HCV genotype infection in HD patients of Khyber Pakhtunkhwa as well as comparing this prevalence data with past studies in Pakistan. Methods Polymerase chain reaction was performed for HCV RNA detection and genotyping in 384 HD patients. The data obtained was compared with available past studies from Pakistan. Results Anti HCV antibodies were observed in 112 (29.2%, of whom 90 (80.4% were HCV RNA positive. In rest of the anti HCV negative patients, HCV RNA was detected in 16 (5.9% patients. The dominant HCV genotypes in HCV infected HD patients were found to be 3a (n = 36, 3b (n = 20, 1a (n = 16, 2a (n = 10, 2b (n = 2, 1b (n = 4, 4a (n = 2, untypeable (n = 10 and mixed (n = 12 genotype. Conclusion This study suggesting that i the prevalence of HCV does not differentiate between past and present infection and continued to be elevated ii HD patients may be a risk for HCV due to the involvement of multiple routes of infections especially poor blood screening of transfused blood and low standard of dialysis procedures in Pakistan and iii need to apply infection control practice.

  4. Referral pattern of hemodialysis patients to nephrologists

    International Nuclear Information System (INIS)

    To determine the referral pattern of dialysis patients to nephrologists and the effects of late referral on clinical, hematological and biochemical parameters in patients presenting for the first-time to dialysis center. This study was conducted on all patients of end stage renal diseases presenting for the first-time for undergoing hemodialysis at our center. Patients with acute renal failure were excluded from the study. At presentation, a history was taken from all the patients regarding seeking of nephrology services and referral pattern. Early and late referral was defined as the time of first referral or admission to a nephrologists greater or less than six months respectively before initiation of hemodialysis. All the patients were examined and their blood sample was drawn at the same time for routine hematological, biochemical parameters (urea, creatinine, serum potassium, calcium, phosphate and albumin) and viral markers (Anti HCV and HbsAg). In this study, 248 patients were enrolled, amongst them, 131 (52.8%) were male and 117 (47.2%) were female. Major causes of renal failure were diabetes mellitus, chronic glomerulonephritis and hypertension. Most of the patients were euvolemic and hypertensive. Sixty percent of patients were having very high urea (>200 mg/dl) and creatinine (>8.0 mg/dl). Most of the patients, 226 (91.1%), were anemic (Hemoglobin <11gm/dl) and 224 (90%) were hypoalbuminemic (serum albumin < 4gm/dl) on first presentation. Majority of patien on first presentation. Majority of patients were hyperkalemic, 139 (56.0%), hypocalcemic, 168 (67.7%) and serum phosphate level was high in only 117 (47%) patients. All the patients presented in emergency room to nephrologists at very late stage (100% late referral), when disease was very much advanced. All of them did not have permanent vascular access for hemodialysis on first presentation to dialysis center. Reasons for late referral were non-availability of nephrologists and nephrology services, non-renal doctors biased, unawareness and training of medical professionals for these patients, patients own denial for dialysis, fear and wrong perception about dialysis procedure, socioeconomic factors and use of non-evidenced based treatment modalities.

    Recent studies have suggested improvements in quality of life (QOL) in patients on quotidian dialysis compared with conventional hemodialysis. Few studies have focused on the burden and QOL in caregivers of patients with end-stage renal disease (ESRD) on nocturnal home hemodialysis (NHD). We aim to assess the caregivers' burden, QOL, and depressive symptoms and to compare these parameters with their patients' counterparts. Cross-sectional surveys were sent to 61 prevalent NHD patients and their caregivers. Surveys assessed demographics, general self-perceived health using the 12-Item Short Form Health Survey (SF-12) and the presence of depression using the Beck Depression Inventory. Subjective burden on caregivers was assessed by the Caregiver Burden scale and was compared with perceived burden by the patients. Thirty-six patients and 31 caregivers completed the survey. The majority of caregivers were female (66%), spouse (81%) with no comorbid illness (72%). Their mean age was 51 ± 11 years. Patients were mostly male (64%) with a median ESRD vintage of 60 months (interquartile range [IQR], 18-136 months) and a mean age of 52 ± 10 years. Compared to caregivers, patients had lower perceived physical health score but had similar mental health score. Depression criteria were present in 47% of patients and 25% of caregivers. Total global burden perceived by either caregivers or patients is relatively low. Although there is a relatively low global burden perceived by caregivers and patients undergoing NHD, a significant proportion of both groups fulfilled criteria for depression. Further innovative approaches are needed to support caregivers and patients performing NHD to reduce the intrusion of caring for a chronic illness and the risk of developing depression.

    Objective: To determine the frequency and leading factors of pulmonary hypertension among chronic hemodialysis patients. Study Design: Case series. Place and Duration of Study: Hemodialysis Unit, Department of Nephrology, Sindh Institute of Urology and Transplantation, Karachi, from September 2011 to March 2012. Methodology: Patients of either gender aged between 16 to 60 years of age undergoing hemodialysis for at least 3 months not having pre-existing valvular heart disease, chronic lung disease or connective tissue disorder were included. Pulmonary hypertension was prospectively estimated by Doppler echocardiogram on patients undergoing dialysis. Pulmonary artery pressure was calculated on the post-dialysis day and leading factors were compared between patients with and without pulmonary hypertension. Results: A total of 178 patients were included in study with male to female ratio120/58 (2.06:1). The mean age was 33.84 +- 11.9 years. The mean duration of hemodialysis was 23.85 +- 22.48 months. Pulmonary hypertension was found in 76 (42.7%) patients. Out of the studied factors, low serum albumin ( 3.4 mg/dl, p = 0.01) was found to be statistically significant in patients with pulmonary hypertension. Conclusion: Pulmonary hypertension was frequently present in dialysis population (42.7%). This subset of patients had significantly lower albumin levels in serum. More research is needed in its pathogenesis to arrest its course. (author)

    Full Text Available ABSTRACT Background Treatment with selective vitamin D receptor activators such as paricalcitol have been shown to exert an anti-inflammatory effect in patients on hemodialysis, in addition to their action on mineral metabolism and independently of parathyroid hormone (PTH levels. The objective of this study was to evaluate the additional antioxidant capacity of paricalcitol in a clinical setting. Methods The study included 19 patients with renal disease on hemodialysis, of whom peripheral blood was obtained for analysis at baseline and three months after starting intravenous paricalcitol treatment. The following oxidizing and inflammatory markers were quantified: malondialdehyde (MDA, nitrites and carbonyl groups, indoleamine 2,3-dioxygenase (IDO, tumor necrosis factor alfa (TNF-?, interleukin-6 (IL-6, interleukin-18 (IL-18 and C-reactive protein (CRP. Of the antioxidants and anti-inflammatory markers, superoxide dismutase (SOD, catalase, reduced glutathione (GSH, thioredoxin, and interleukin-10 (IL-10 levels were obtained. Results Baseline levels of oxidation markers MDA, nitric oxide and protein carbonyl groups significantly decreased after three months on paricalcitol treatment, while levels of GSH, thioredoxin, catalase and SOD activity significantly increased. After paricalcitol treatment, levels of the inflammatory markers CRP, TNF-?, IL-6 and IL-18 were significantly reduced in serum and the level of anti-inflammatory cytokine IL-10 was increased. Conclusions In renal patients undergoing hemodialysis, paricalcitol treatment significantly reduces oxidative stress and inflammation, two well known factors leading to cardiovascular damage.

  8. ADIPONECTIN LEVELS AND ATHEROSCLEROTIC RISK FACTORS IN CHILDREN ON HEMODIALYSIS

    International Nuclear Information System (INIS)

    Atherosclerotic cardiovascular disease (ACVD) is the major cause of mortality in patients with end stage renal disease (ESRD) treated with hemodialysis (HD), even in children. Adiponectin (ADPN) is an adipocyte derived plasma protein having anti-atherogenic properties. ADPN levels are elevated in ESRD but it has been reported that ESRD patients with low plasma ADPN levels have a high risk of cardiovascular death. The aim of this study is to evaluate the relation between ADPN and atherosclerotic risk factors in children on hemodialysis.Twenty-eight children (17 boys and 11girls) with a mean age of 10.6 ± 3.34 years undergoing hemodialysis (HD) for a mean period of 11.96 ± 8.32 months (ranged from 6 to 36 months) and 10 healthy age and sex matched control subjects were enrolled in this study. The acute effect of a hemodialysis session on serum ADPN and other atherosclerotic risk factors , including blood pressure, serum lipids, C-reactive protein (CRP) and tumor necrosis factor-? (TNF-?) were assessed by comparison of pre- and post-hemodialysis determinations. Serum levels of ADPN and TNF-? were measured by enzyme linked immunosorbant assay (ELISA) while CRP was measured by the semi-quantitative latex agglutination assay.The data showed that serum ADPN levels were twice higher in the HD group as compared to the control subjects. Concerning the atherosclerotic risk factors, TNF-?, CRP and triglycerides levels showed significant elevation in the HD group. Meanwhile,levation in the HD group. Meanwhile, serum albumin, cholesterol and phosphorus levels showed significant decreases. The linear regression analysis showed that adiponectin was negatively correlated with glomerular filtration rate (GFR) (r = -0.68,P < 0.0001), and body mass index (r = -0.73, P < 0.0007); ADPN levels are directly related to HDL cholesterol levels (r = 0.76, P < 0.0001) and inversely related to triglycerides level (r = -0.63, P < 0.0003). No relationship was found between adiponectin and CRP.It could be concluded that patients on regular hemodialysis were at increased risk for premature atherosclerosis due to high levels of CRP, LDL-cholesterol and triglycerides. The elevated ADPN levels in the hemodialyzed patients may have a protective role against atherosclerosis

    Continuous or intermittent use of unfractioned heparin is the anticoagulant of choice to prevent the extracorporeal circulation clotting during the hemodialysis session. However, low molecular weight heparin (LMVH) could be an alternative treatment especially in case of high risk bleeding or during some clinical conditions such as diabetes mellitus, cerebrovascular bleeding, malignant hypertension. LMVH may be given as a single initial bolus injection generally adequate. Heparinization must be lowered or stopped when an effective anticoagulation is previously used. PMID:9675763

    Iliopsoas abscess is a rare complication in hemodialysis patients that is mainly due to adjacent catheterization, local acupuncture, discitis, and bacteremia. Herein, we report a 47-year-old woman undergoing regular hemodialysis via a catheter in the internal jugular vein who presented with low back pain and dyspnea. A heart murmur suggested the presence of catheter-related endocarditis, and this was confirmed by an echocardiogram and a blood culture of methicillin-resistant Staphylococcus aureus. A computed tomography indicated a pulmonary embolism and an incidental finding of iliopsoas abscess. Following surgical intervention and intravenous daptomycin, the patient experienced full recovery and a return to usual activities. This case indicates that an iliopsoas abscess can be related to a jugular vein catheter, which is apparently facilitated by infective endocarditis. The possibility of iliopsoas abscess should be considered when a hemodialysis patient presents with severe low back pain, even when there is no history of adjacent mechanical intervention.

    Full Text Available Objective: To identify the factors that may influence survival inpatients on chronic hemodialysis at a private hospital in Brazil.Methods: In this study, 99 patients in the CDE (Hemodialysis Unitof Hospital Albert Einstein undergoing chronic hemodialysis for atleast 3 months were evaluated retrospectively over the period fromFebruary 2000 to October 2006. The following patient characteristicswere evaluated as possibly having an influence on survival: cause ofchronic renal failure (with and without diabetes mellitus, sex, age,albumin levels, C-reactive protein (CRP, hemoglobin levels and ICED(Index of Coexisting Disease, an instrument to assess the presence andseverity of comorbidities. Statistical analysis: Survival curves werecalculated by the Kaplan-Meyer method and the differences betweenthe curves were evaluated by a log-rank test. Results: The mean ageof patients was 63.14 ± 16.18 years, 34% of them were female and40% of them presented diabetes mellitus as the cause of chronic renalfailure. Mean albumin and hemoglobin levels on admission were 3.44± 0.58 g/dl and 10.55 ± 1.51 g/dl, respectively, and median CRP levelwas 9.55 g/dl. The distribution of patients by ICED was mild (25%,moderate (36% and severe (38%. Thirty-three (33% patients died,24 (24% underwent renal transplantation, 5 (5% were transferredto another dialysis unit, 36 (36% continued dialysis treatment and1 (1% recovered renal function. One-year survival was 80% and themedian survival period was 42.34 months (95% CI: 28.06-54.84.In univariate analysis, the following variables were associated withsurvival of patients: CRP levels on admission (RR: 1.39; 95% CI: 1.04-1.85; p = 0.026, age (RR: 1.049; 95% CI: 1.017-1.082; p = 0.028and the level of ICED 3 compared with the level of ICED 1 (RR: 9.25;95% CI: 1.23-69.48; p = 0.03. In multivariate analysis, the followingvariables were associated with survival of patients: age (p = 0.0025and severe ICED compared with mild ICED (p = 0.0341. Conclusion:The factors associated with survival of patients were advanced ageand severity of comorbidities. The utilization of ICED enables stratifyingthe dialysis patients according to severity of their comorbidities andit is useful to identify the patients with a greater risk of death andhospitalization, as well as to aid in the forecast of and optimization ofresources necessary for their treatment.

    Full Text Available Background: Monitoring of superior vena cava saturation (ScvO2 has become routine in the management of pediatric patients undergoing cardiac surgery. The objective of our study was to evaluate the correlation between continuous ScvO2 by the application of a fiber-optic oximetry catheter (PediaSat and intermittent ScvO2 by using standard blood gas measurements. These results were compared to those obtained by cerebral near infrared spectroscopy (cNIRS. Setting: Tertiary pediatric cardiac intensive care unit (PCICU. Methods and main results: A retrospective study was conducted in consecutive patients who were monitored with a 4.5 or 5.5 F PediaSat catheter into the right internal jugular vein. An in vivo calibration was performed once the patient was transferred to the PCICU and re-calibration took place every 24 hours thereafter. Each patient had a NIRS placed on the forehead. Saturations were collected every 4 hours until extubation. Ten patients with a median age of 2.2 (0.13-8.5 years and a weight of 12.4 (3.9-24 kg were enrolled. Median sampling time was 32 (19-44 hours: 64 pairs of PediaSat and ScVO2 saturations showed a poor correlation (r=0.62, 95% CI 44-75; p<0.0001 and Bland Altman analysis for repeated measures showed an average difference of 0.34 with a standard deviation of 7,9 and 95% limits of agreement from -15 to 16. Thirty-six pairs of cNIRS and ScVO2 saturations showed a fair correlation (r=0.79, 95% CI 0.60-0.89; p<0.0001 an average difference of -1.4 with a standard deviation of 6 and 95% limits of agreement from -13 to 10. Analysis of median percentage differences between PediaSat and ScvO2 saturation over time revealed that, although not statistically significant, the change in percentage saturation differences was clinically relevant after the 8th hour from calibration (from -100 to +100%. Conclusion: PediaSat catheters showed unreliable performance in our cohort. It should be further investigated whether repeating calibrations every 8 hours may improve the accuracy of this system. CNIRS may provide similar results with a lower invasiveness.

    Full Text Available PURPOSE: To analyze the effect of maintenance hemodialysis on left ventricular diastolic function in patients with end-stage renal disease. METHODS: Study population consisted of 42 patients with end-stage renal disease. Before an arteriovenous fistula was surgically created, the patients were evaluated by conventional and Doppler echocardiography and Doppler tissue imaging. Then, the patients undergoing hemodialysis treatment when the arteriovenous fistula was compleated. After the first hemodialysis session (mean 76.14 ± 11.37 days the second echocardiographic evaluations were performed. RESULTS: Mean age was 58 ± 13 years and 21 (%50 of the patients were female. After maintenance hemodialysis treatment; peak early (E and peak late (A diastolic mitral inflow velocities and E/A ratio were not significantly change however the deceleration time of E wave and left atrial diameter were significantly increased. Also there was no change in the early (Em and late (Am diastolic myocardial velocities and Em/Am ratios of lateral and septal walls of left ventricular. E/Em ratio was decreased insignificantly. Pulmonary vein velocities and right ventricular functions are remained almost unchanged after hemodialysis treatment. DISCUSSION: The acute and long-term effect of hemodialysis on left ventricular diastolic function is unclearly. Patients with end-stage renal disease treatment with hemodialysis via arteriovenous fistula experience a variety of hemodynamic and metabolic abnormalities that predispose to alterations in left and right ventricular functions. The present study showed that left ventricular diastolic function except left atrial diameter and right ventricular functions were not significantly change, however left ventricular systolic functions were impaired after maintenance hemodialysis treatment in patients with end-stage renal disease. CONCLUSION: It has been suggested that echocardiographic parameters are useful markers for evaluation of left ventricular and right ventricular functions in patients with end-stage renal disease. However, in patients with endstage renal disease treated with hemodialysis, repeated assessment of echocardiographic examinations to observe serial changes in left and right ventricular functions are not yet well established. In this study, we showed that acute changes of volume status and electrolytes and autonomic regulation by hemodialysis session did not affect left ventricular diastolic and right ventricular functions in a relatively long term.

    Plasma cystatin C is an emerging parameter to assess kidney function. Its utility in assessing the adequacy of hemodialysis in patients with end-stage-renal disease has however not been established with certainty. This study was therefore carried out to assess the usefulness of serum cystatin C estimation in patients undergoing low flux membrane hemodialysis. Serum creatinine and cystatin C were estimated in 20 patients before and after undergoing hemodialysis. The mean serum creatinine decreased from a pre-dialysis value of 7.72 mg/dL to a post-dialysis value of 2.90 mg/dL. On the contrary, the mean serum cystatin C levels were found to increase from a pre-dialysis value of 5.97 mg/L to a post-dialysis value of 8.25 mg/L. Therefore, serum cystatin C cannot be used to monitor dialysis adequacy. It however, serves as a surrogate marker of the inadequacy of low flux membrane bicarbonate hemodialysis in clearing low molecular weight proteins from the circulation. PMID:23105882

    Cutaneous disorders can precede or follow the initiation of hemodialysis treatment. We evaluated the prevalence of various dermatological manifestations in patients undergoing hemodialysis at least twice a week for minimum of three months at our center. Patients were excluded if they were undergoing hemodialysis less than twice a week or on hemodialysis secondary to ESRD following graft dysfunction. One hundred and forty-three patients were evaluated. Among them, there were 113 male and 30 females. Among the skin changes, pruritus accounted for 56%, Xerosis was observed in 52%, Diffuse blackish hyper pigmentation was seen in 40%. Skin infections was seen in 53% of patients, of these fungal, bacterial and viral infections were 27.2%, 14.6%, and 11.2%, respectively. Kyrle's disease was observed only in 6.9%. Other skin manifestations include eczema 4.8%, psoriasis 2.7%, and drug rash 2.1%. Nail changes were observed in 46 patients of whom 27 patients had onychomycosis. Other changes include discoloration, onycholysis, and splinter hemorrhages. Hair changes were observed in 21.7%. Mucosal changes were seen in 27.3%. In our study, pruritus, xerosis, and pigmentation were higher among skin changes. Recognition and management of some of these dermatological manifestations vastly reduce the morbidity and improve the quality of life. PMID:22830039

    Three times weekly home hemodialysis (HHD) was introduced shortly after the initiation of chronic hemodialysis (HD) treatment in 1960. HHD eliminates the need of transportation to and from the dialysis unit and by allowing patients to set their own dialysis schedule, decreases the burden of treatment on their personal and professional lives. HHD has been found more economical and more highly associated with better patient survival than in-center dialysis. Nevertheless, the global prevalence of HHD decreased between 1980 and 2000 due to the increased availability of dialysis units and continuous ambulatory peritoneal dialysis, advances in cadaveric kidney transplantation, and several other factors. However, the availability of HHD at a frequency of more than 3 times/week, the typical frequency of conventional HD (CHD), in such forms as brief HD sessions of 2-3 h 5-6 days/week and nocturnal HD (NHD) has led to reversals in this trend. Frequent HHD, such as short daily HD (SDHD) and NHD instead of 3 times/week CHD, has been found to significantly improve hypertension, left ventricular mass, renal anemia, quality of life and mortality. On the other hand, NHD has been found to significantly improve hypertension, left ventricular mass, renal anemia, quality of life, malnutrition, mortality and phosphate clearance. Many observational clinical studies and one randomized controlled trial of SDHD and/or NHD have been conducted, and compact and convenient dialysis machines have been developed and used for HHD. The most recent data reported in the national and local registries of selected countries indicate that the prevalence of HHD among all dialysis patients from 2008 to 2010 varied from 0 to 3.3% except in New Zealand and Australia, where it was 16.3 and 9.3%, respectively. As HHD appears to be a more effective and economical dialysis modality than in-center CHD, its prevalence is likely to increase in the future. PMID:22613921

    The insertion of non-tunneled temporary hemodialysis catheters (NTHCs) is a core procedure of nephrology practice. While urgent dialysis may be life-saving, mechanical and infectious complications related to the insertion of NTHCs can be fatal. In recent years, various techniques that reduce mechanical and infectious complications related to NTHCs have been described. Evidence now suggests that ultrasound guidance should be used for internal jugular and femoral vein NTHC insertions. The imple...

    Full Text Available 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 dialysis treatment: peritoneal dialysis (126 patients), arteriovenous fistula hemodialysis (326 patients), and catheter hemodialysis (192 patients). RESULTS: One hundred sixteen patients (18.01%) developed infection. There was a higher incidence of infection in the peritoneal dialysis group (44 patients; 34.92%; OR: 3.32; CI 95% = 2.13-5.17; p = 0.0001). In the catheter hemodialysis group, 48 patients (25%) had infection (OR: 1.88; CI 95%: 1.24-2.85; p = 0.0035). In the arteriovenous fistula hemodialysis group, 24 patients (7.36%) developed infection (OR: 0.19; CI 95%: 0.12-0.31; p = 0.0001). Five patients (4.31%) died due to infection (four in the peritoneal dialysis group and one in the catheter hemodialysis group). There were no deaths due to infection in the arteriovenous fistula hemodialysis group. CONCLUSIONS: Peritoneal dialysis is the treatment with greater risk of infection and mortality, followed by catheter hemodialysis. The lowest risk of infection and mortality was observed in arteriovenous fistula hemodialysis group.

    Aside from a decrease in the high-density lipoprotein (HDL) cholesterol levels, qualitative abnormalities of HDL can contribute to an increase in cardiovascular (CV) risk in end-stage renal disease (ESRD) patients undergoing chronic hemodialysis (HD). Dysfunctional HDL leads to an alteration of reverse cholesterol transport and the antioxidant and anti-inflammatory properties of HDL. In this study, a quantitative proteomics approach, based on iTRAQ labeling and nanoflow liquid chromatography ...

    Full Text Available Background: Chronic renal failure (CRF presents with an array of cutaneous manifestations. Newer changes are being described since the advent of hemodialysis, which prolongs the life expectancy, giving time for these changes to manifest. Aim: The aim of this study was to evaluate the prevalence of dermatologic problems among patients with chronic renal failure (CRF undergoing hemodialysis. Methods: One hundred patients with CRF on hemodialysis were examined for cutaneous changes. Results: Eighty-two per cent patients complained of some skin problem. However, on examination, all patients had at least one skin lesion attributable to CRF. The most prevalent finding was xerosis (79%, followed by pallor (60%, pruritus (53% and cutaneous pigmentation (43%. Other cutaneous manifestations included Kyrle?s disease (21%; fungal (30%, bacterial (13% and viral (12% infections; uremic frost (3%; purpura (9%; gynecomastia (1%; and dermatitis (2%. The nail changes included half and half nail (21%, koilonychia (18%, onychomycosis (19%, subungual hyperkeratosis (12%, onycholysis (10%, splinter hemorrhages (5%, Mees? lines (7%, Muehrcke?s lines (5% and Beau?s lines (2%. Hair changes included sparse body hair (30%, sparse scalp hair (11% and brittle and lusterless hair (16%. Oral changes included macroglossia with teeth markings (35%, xerostomia (31%, ulcerative stomatitis (29%, angular cheilitis (12% and uremic breath (8%. Some rare manifestations of CRF like uremic frost, gynecomastia and pseudo-Kaposi?s sarcoma were also observed. Conclusions: CRF is associated with a complex array of cutaneous manifestations caused either by the disease or by treatment. The commonest are xerosis and pruritus and the early recognition of cutaneous signs can relieve suffering and decrease morbidity.

    Full Text Available Background and Aims: Hemodialysis (HD patients seem to be at considerable risk of acquiring HBV infection. This study was carried out to determine the seroprevalence of hepatitis B virus (HBV infection in hemodialysis patients living in the province of Tehran and to investigate the association between viral hepatitis B and the probable risk factors for HD patients..Methods: From June to August 2005, this study was done on the entire HD population of the province of Tehran (2630 patients; 1505 males and 1125 females, mean age: 53.4 years. Social and demographic data, date of onset of HD, length of time receiving HD services, history of a kidney transplant, multiple sex partners, and other probable risk factors were evaluated. Blood samples were tested for liver enzyme levels as well as human immunodeficiency virus (HIV 1, HIV 2, hepatitis B surface antigen (HBsAg, hepatitis B surface antibody (anti-HBs, and hepatitis C antibody (anti-HCV..Results: A total of 64 patients were HBsAg positive (2.4%. The male-to-female ratio was 45/19 for HBsAg-positive patients and 1462/1104 for the remaining patients (P = 0.03, respectively. Except for nationality (P < 0.001, previous kidney transplants (P < 0.001, age (P < 0.001, and transient HD (P < 0.001, no association was found between HBV infection and probable risk factors..Conclusions: Common erythropoietin administration, blood testing for transfusion purposes, implementation of universal precaution in dialysis units as well as the use of dedicated machines for HBV-infected patients has led to a decreasing trend of HBV infection. Periodic surveillance of HBV infection among patients undergoing hemodialysis is strongly recommended.

Recently, B-type (brain natriuretic peptide (BNP has been defined as an itch-selective neuropeptide in pruriceptive neurons in mice, and higher serum levels of BNP are frequently observed in hemodialysis patients. The objective of the present study was to evaluate the role of serum BNP in pruritus in patients undergoing hemodialysis. Patients and methods: The current cross-sectional study was performed on 43 patients undergoing maintenance hemodialysis. A visual analog scale (VAS measuring the general severity of pruritus (values from 0 to 10, with higher values indicating more severe pruritus in daytime and at night was self-reported by patients. Each patient's background and laboratory tests, including serum BNP in the post-hemodialysis period, were collected. The correlation between VAS and clinical parameters was evaluated. Results: Both daytime and nighttime VAS scores in diabetic patients were significantly less than those in nondiabetic patients. Multiple regression analysis revealed that pruritus in daytime was worsened by serum BNP (?=2.0, t=2.4, P=0.03, calcium (?=4.4, t=5.2, P<0.0001, and ?2-microglobulin (?=2.0, t=3.0, P=0.007, while it was eased by age (?=–2.2, t=-3.2, P=0.0004. Nocturnal pruritus was severe in nondiabetic patients (?=1.7, t=3.8, P=0.0005 and weakened by the total iron binding capacity (?=–2.9, t=–3.1, P=0.004. Conclusion: It is suggested that a higher level of serum BNP increases the pruritus of hemodialysis patients in daytime and that diabetic patients are less sensitive to itch, especially at nighttime.

  11. Dialyzability of gadodiamide in hemodialysis patients

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the contrast enhancement, pharmacokinetics, dialyzability, and safety of gadodiamide in patients on hemodialysis. Thirteen hemodialysis patients with abdominal disease were examined after receiving intravenous gadodiamide (0.1 mmol/kg body weight) by magnetic resonance imaging (MRI) and were dialyzed at 1, 3, 5, and 8 days. Blood samples were obtained immediately before, during, and at the end of the first hemodialysis session and immediately before and at the end of the next three sessions. The complete blood count, blood biochemistry, ?2-microglobulin, and gadolinium were measured. Dialysis of urea, creatinine, and gadolinium during the first hemodialysis session was assessed. Precontrast and postcontrast MRI and Gd-enhanced MR angiography (MRA) images were reviewed and visually evaluated by two radiologists; their evaluation was based on consensus. Gadodiamide did not cause any changes in renal function. An average of 73.8%, 92.4%, and 98.9% of the gadodiamide dose was eliminated by the end of the first, second, and third hemodialysis sessions, respectively. The average half-time of gadodiamide was 1.93 h (SD 0.55). The mean clearance of gadodiamide during hemodialysis was 63.5 ml/min (SD 21.9). There were no side effects related to the injection of gadodiamide. In all cases, diagnosable MRI and MRA images were obtained after gadodiamide injection in the hemodialysis patients. In hemodialysis patients, gadodiamide a. In hemodialysis patients, gadodiamide achieves diagnosable images. It is dialyzable and can be used safely without measures to increase excretion. (author)

    Pain during areteriovenous fistula (AVF) cannulation remains a common problem in hemodialysis (HD) patients. This study was undertaken to assess the effect of cryotherapy on pain due to arteriovenous fistula puncture in hemodialysis patients. A convenience sample of 60 patients (30 each in experimental and control groups) who were undergoing hemodialysis by using AVF, was assessed in a randomized control trial. Hemodialysis patients who met the inclusion criteria, were randomly assigned to experimental and control groups using a randomization table. Objective and subjective pain scoring was done on two consecutive days of HD treatment (with cryotherapy for the experimental and without cryotherapy for the control group). The tools used were a questionnaire examining demographic and clinical characteristics, an observation checklist for assessing objective pain behavior, and a numerical rating scale for subjective pain assessment. Descriptive statistics were used as deemed appropriate. Chi square, two-sample and paired t-tests, the Mann Whitney test, Wilcoxon's signed rank test, the Kruskal Wallis test, and Spearman's and Pearson's correlations were used for inferential statistics. We found that the objective and subjective pain scores were found to be significantly (P = 0.001) reduced within the experimental group with the application of cryotherapy. This study highlights the need for adopting alternative therapies such as cryotherapy for effective pain management in hospital settings. PMID:20142927

  13. Hemodialysis-related arthropathy. A prospective MR study with SE and GRE sequences

    International Nuclear Information System (INIS)

    Purpose: A prospective examination of hemodialysis-related arthropathy by MR imaging with SE and GRE sequences was undertaken to verify whether the low signal intensity on T2-weighted SE images is caused by a paramagnetic susceptibility effect derived from amyloid or from hemosiderin. Material and Methods: Twenty-seven joints (19 hip joints, 6 discovertebral joints of 5 lumbosacral spines and 1 cervical spine, 2 shoulder joints) in 14 patients undergoing long-term hemodialysis (duration 10-22 years, mean 17) were examined with SE T1-weighted, T2-weighted and GRE T2*-weighted sequences. Results: The signal intensity of the intraarticular and periarticular masses of the involved joints was basically isointense to the muscle in all 3 pulse sequences. No significantly low signal area was found on GRE T2*-weighted images. Conclusion: The low signal areas in the hemodialysis-related arthropathy on SE T2-weighted images are not caused by a paramagnetic susceptibility effect, but probably by the hypocellular and fibrous nature of amyloid-containing tissues. Therefore the GRE sequence can be helpful for differentiating hemodialysis-related amyloid arthropathy from chronic hemarthrosis or juxta-articular brown tumor. (orig.)

  14. Radiology of the kidneys in patients under maintenance hemodialysis

    International Nuclear Information System (INIS)

    The kidneys of patients with chronic renal failure undergoing maintenance hemodialysis may show different variances or complications. Most common are secondarily acquired renal cysts, which my be found in as many as 92% of patients after 8 years of hemodialysis. Single (in 12.5% of patients) or multiple (8.3%) cysts with bleeding are common; additionally, hematuria or ruptured cysts may be found. Bleeding into cysts is more common in patients with autosomal dominant polycystic kidney disease. Due to the decreasing urinary production development of kidney stones is very uncommon, but calcification in or around cysts can be found in 71% of patients. Kidney tumors occur 41 times more often in patients with chronic renal failure than in patients without kidney disease. We detected tumors in 4.2% of our patients on long-term dialysis. Diagnostic differentiation of the relatively slow growing and fairly late metastasizing malignant tumors from adenomas is not possible. Nevertheless, we screen our patients every 3-4 years. Computed tomography is superior to ultrasonography for this purpose, because ultrasonography lacks the necessary sensitivity in this group of patients. (orig.)

  15. Optimizing lithium dosing in hemodialysis

    2006-01-01

    We studied a 62-year-old female hemodialysis patient during initiation and maintenance of lithium carbonate therapy. Three different methods were applied to estimate the regimen: a scenario based on volume of distribution (V(d)), a scenario based on glomerular filtration rate (GFR), and a scenario in which we developed an algorithm based on a 2-compartment distribution without elimination. The GFR estimate led to plasma concentrations 3-4 times lower than those anticipated. In contrast, the estimates based on V(d) and the algorithm derived from pharmacokinetic modeling led to comparable loading dose estimates. Furthermore, the maintenance dose estimated from the central compartment (V1) led to plasma concentrations within the therapeutic range. Thus, a regimen where 12.2 mmol lithium was given after each hemodialysis session resulted in stable between-dialysis plasma lithium concentrations in this patient with no residual kidney function. We did not observe adverse effects related to this regimen, which was monitored from 18 days to 8 months of therapy, and the patient experienced relief from her severe depressive disorder. In conclusion, dialysis patients may be treated with lithium administrated immediately postdialysis. Further observations are necessary to obtain robust long-term safety data and to optimize the monitoring schedule.

    Full Text Available Background: The effect of kind of dialysis solution on the control of blood pressure and adequacy and efficacy of hemodialysis is a most debated and controversial issue.Methods: Twenty six chronic hemodialized patients in Ghaem hemodialysis center, Mashhad, Iran, in winter of the year 2004, enrolled this study for one month. The patients were dialyzed with bicarbonate buffer and were dialyzed in the next month with acetate. The kind of membranes and the dialysis machines were the same in both months. Systolic and diastolic pressures were measured before and after hemodialysis in at least three hemodialysis sessions, and he means recorded. The mean of the body weight were also recorded. In the same sessions of hemodialysis by measuring the urea, before and after hemodialysis, urea reduction ratio (URR, was also calculated. Statistical analysis was done with paired student t test for paired measurement, and independent t test for evaluating the effect of the kind of dialysate buffer on the measured parameters.Results: There were no significant statistical differences between acetate and bicarbonate dialysis solution buffers in the control of diastolic blood pressure. But use of acetate buffer resulted in more significant systolic blood pressure reduction compared with bicarbonate buffer (p=0.045. When adequacy of hemodialysis were compared between two kinds of buffers there were no significant statistical differences between them. When the effect of dialysate sodium concentration in the range utilized in two buffers, was evaluated on the systolic and diastolic pressure reduction, no significant differences, between two types of buffers attributable to the difference between dialysates sodium concentrations were found.Conclusion: Hemodialysis with both, acetate and bicarbonate buffers results in significant reductions in systolic and diastolic blood pressure, weight and urea ratio. Use of acetate buffer is more significantly associated with systolic blood pressure reduction compared to bicarbonate buffer (p=0.045, this effect is independent of the dialysate buffer sodium concentration.

    Hitherto, there has been no systematic evaluation of the nutritional status of HD patients in Thailand. 27 patients awaiting renal transplantation, 19 M 8 F, age 47.2 +/- 8.6 y (mean +/- SD), underwent HD at Ramathibodi Hospital. Dietary assessment revealed the average daily intake of men and women to be respectively 1571 +/- 314 and 1379 +/- 403 kcal, 47 +/- 11 and 42 +/- 14 g protein. Anthropometric data showed that mean of BMI, percent ideal body weight (%IBW), percent standard triceps skinfold thickness (%TSF) and percent arm muscle circumference (%std MUAMC) to be 20.5 +/- 2.6 kg/m2, 90 +/- 12, 75 +/- 30 and 100 +/- 13, respectively. However, 37%, 56% and 70% of these patients had BMI, BW and MUAC less than the minimal cut-off levels. These data reflect the importance of energy depletion in these patients. The average serum albumin was 39 +/- 6 g/L while 52% suffered from low albumin levels. TC, LDL-C, HDL-C and TG were 4.34 +/- 1.34, 2.9 +/- 1.06, 0.89 +/- 0.33 and 1.10 +/- 0.67 mmol/L while 15% had high TC, LDL-C and 58% had low HDL-C levels. Only one patient was suffered from hypertriglyceridemia. Whereas inadequate thiamine, riboflavin, ascorbic acid and alpha-tocopherol status were present in 4-30%, toxic levels of serum retinol were seen in almost all patients. Low serum zinc and copper levels were also present. This study disclosed a wide spectrum of nutritional problems usually overlooked in CRF patients undergoing chronic hemodialysis. Whereas zinc supplementation may be needed, vitamin A supplementation in these patients should be discouraged. PMID:8886340

  18. Serum trypsin inhibitory capacity in hemodialysis patients

    International Nuclear Information System (INIS)

    It has been established that overproduction of reactive oxygen species (ROS) occurs during hemodialysis causing oxidation of proteins. Alpha-1-antitrypsin is the major circulating anti-protease which contains methionine in the active site. The aim of the present study was to measure the level of serum trypsin inhibitory capacity (sTIC) in hemodialysis patients. This case-control study was performed in 52 hemodialysis patients and 49 healthy controls. sTIC was measured by enzymatic assay. The sTIC was significantly (P< 0.001) lower in hemodialysis patients (1.87 + - 0.67 micron mol/min/mL) than healthy controls (2.83 + - 0.44 micron mol/min/L). Reduction of sTIC may be due to the oxidation of methionine residue in the reactive site of alpha-1 antitrypsin. (author)

    A systematic study of the upper cervical spine was performed using magnetic resonance imaging in 25 patients (15 men and 10 women) who had been undergoing hemodialysis for more than 10 years. Seven pseudotumors of the periodontoid soft tissue were disclosed, which were similar to the pannus recently described in rheumatoid arthritis. Bone cystic radiolucencies were observed in association with these pseudotumors in 5 patients. The radiolucencies were located in the atlas (1 in the lateral mass and 1 in the anterior branch) and in the axis (3 in the odontoid process and 1 in the vertebral body). No horizontal or vertical atlantoaxial subluxation was demonstrated. These features were observed only in patients who had amyloid arthropathy. They could be a frequent, yet thus far little-recognized, feature of beta 2-microglobulin amyloidosis. PMID:2222537

    Over the past 20 years children have benefited from major improvements in both technology and clinical management of dialysis. Morbidity during dialysis sessions has decreased with seizures being exceptional and hypotensive episodes rare. Pain and discomfort have been reduced with the use of chronic internal jugular venous catheters and anesthetic creams for fistula puncture. Non-invasive technologies to assess patient target dry weight and access flow can significantly reduce patient morbidity and health care costs. The development of urea kinetic modeling enables calculation of the dialysis dose delivery, Kt/V, and an indirect assessment of the intake. Nutritional assessment and support are of major importance for the growing child. Even if the validity of these "urea only" data is questioned, their analysis provides information useful for follow-up. Newer machines provide more precise control of ultrafiltration by volumetric assessment and continuous blood volume monitoring during dialysis sessions. Buffered bicarbonate solutions are now standard and more biocompatible synthetic membranes and specific small size material dialyzers and tubing have been developed for young infants. More recently, the concept of "ultrapure" dialysate, i.e. free from microbiological contamination and endotoxins, has developed. This will enable the use of hemodiafiltration, especially with the on-line option, which has many theoretical advantages and should be considered in the case of maximum/optimum dialysis need. Although the optimum dialysis dose requirement for children remains uncertain, reports of longer duration and/or daily dialysis show they are more effective for phosphate control than conventional hemodialysis and should be considered at least for some high-risk patients with cardiovascular impairment. In children hemodialysis has to be individualized and viewed as an "integrated therapy" considering their long-term exposure to chronic renal failure treatment. Dialysis is seen only as a temporary measure for children compared with renal transplantation because this enables the best chance of rehabilitation in terms of educational and psychosocial functioning. In long term chronic dialysis, however, the highest standards should be applied to these children to preserve their future "cardiovascular life" which might include more dialysis time and on-line hemodiafiltration with synthetic high flux membranes if we are able to improve on the rather restricted concept of small-solute urea dialysis clearance.

    Full Text Available Hepatitis Delta Virus (HDV is a small defective virus that replicates only in the presence of Hepatitis B surface Antigen (HBsAg (1. The epidemiology of HDV infection is similar to HBV but with notable exceptions. Evidence of HDV infection was found all around the world. It is estimated that approximately 5% of HBsAg carriers are infected with HDV infection all around the world. HDV infection occurs worldwide but incidence and prevalence data are limited due to inaccurate reporting and delayed detection. It is more difficult to determine the number of cases of acute or fulminant hepatitis related to HDV infection, as the incidence varies among continents, countries, and regions. In general, three epidemiological patterns of HDV infection can be identified. They include the endemic pattern (such as what occurs in southern Italy and Greece, the epidemic pattern (epidemics have been reported in the Amazon Basin of Venezuela, and the occurrence of HDV infection among high-risk groups such as intravenous drug users (in developed Western countries. The epidemiology of HDV infection seems to be changing in some regions. Vaccination against HBV, decrease in HBV infection and thus in the pool of HBsAg carriers who may be infected with HDV are responsible for this decrease. Immigration patterns can be expected to have an impact on HDV infection. Nonetheless, it continues to represent a public health problem in some parts of the world yet (2-5. HBV infection in dialysis patients varies among different localities and correlates with the endemicity in the general population of the region. HBV prevalence has decreased in many countries in general population and dialysis patients. Improvement of people's knowledge about risk factors, national vaccination programs for neonates and vaccination of high risk groups are responsible for these decrease in prevalence of HBV infection in general population (6. The overall incidence and prevalence of HBV infection in dialysis patients has decreased over the years as a result of routine screening of blood products for HBsAg, the advent of recombinant human erythropoietin, HBV vaccination and the implementation of infection control measures (7, 8. However, the prevalence and incidence rates of HBsAg positivity are still high among patients undergoing maintenance hemodialysis in the less developed countries (9.Transmission of HDV is similar to HBV, via blood and blood fluids containing the virus, and infection occurs by parenteral routs (10. Dialysis patients may acquire HDV infection as they are at risk of hepatitis B infection. The information on the epidemiology of HDV infection in the dialysis patients is limited. This may be in part related to limited use or availability of delta testing. In European countries, such as France, Sweden, and the USA, HDV infection is restricted to high risk group of drug addicts and has decreased during recent years (11. There are some reports of acute and fulminant hepatitis or symptom-free transmission in dialysis patients with HBV and HDV infections (12-14. The prevalence was different from zero to 44.5% in hemodialysis patients (15, 16. The prevalence of HDV in different groups is related to routs of transmission. In Iran, the main route for HBV transmission was vertical in past (6, 17 and the difference between the prevalence of HDV infection in hemodialysis patients (44.5% and asymptomatic carriers (2.5% is meaningful (15.Delta virus is of particular potential concern in hemodialysis units where segregation of HBsAg positive atients to minimize hepatitis B transmission to susceptible patients may facilitate the transmission of delta agent (18. HDV infection is not important in developed countries, but may be a major risk for fulminant hepatitis in hemodialysis patients with HBV infection in developing countries. The importance of HDV is rising due to immigration phenomenon from area of developing countries. I recommend periodic testing for HDV infection by anti-HDV antibody in HBsAg positive carriers on chronic hemodialysis treatment.

    Full Text Available Background & Aim: Physical and psychosocial problems along with the changes in life style, put hemodialysis patients under pressure. It seems that social support decreases psychological stresses and improves quality of life. This study aimed to describe hemodialysis patients' perceptions on their social supports and related factors. Methods & Materials: This descriptive-correlational study is a part of a larger study. All patients (n=202 referred to the hemodialysis units of Iran University of Medical Sciences were recruited to the study during a four-months period. Data were collected using "Personal Resources Questionnaire" (PRQ 85-PART 2 and analyzed using SPSS v.14. Results: Findings revealed that the most patients (64.9% had perceived social support at high levels. There were significant relationships between social support with economic status, gender and marital status (P<0.05. Findings also indicated that the statements of "I enjoy doing little extra things that make another person's life more pleasant" and, "I belong to a group in which I feel important" had the highest and lowest scores respectively. Conclusion: Regarding the variety of perceptions in hemodialysis patients on social support and its related factors, nurses can prevent social isolation of these patients through identification of high risk groups and can also reduce their stresses and help them to improve their quality of life by providing adequate supportive interventions.   Key words: emotional support, hemodialysis patients, perceived social support

    The insertion of non-tunneled temporary hemodialysis catheters (NTHCs) is a core procedure of nephrology practice. While urgent dialysis may be life-saving, mechanical and infectious complications related to the insertion of NTHCs can be fatal. In recent years, various techniques that reduce mechanical and infectious complications related to NTHCs have been described. Evidence now suggests that ultrasound guidance should be used for internal jugular and femoral vein NTHC insertions. The implementation of evidence-based infection-control 'bundles' for central venous catheter insertions has significantly reduced the incidence of bloodstream infections in the intensive care unit setting with important implications for how nephrologists should insert NTHCs. In addition, the Cathedia Study has provided the first high-level evidence about the optimal site of NTHC insertion, as it relates to the risk of infection and catheter dysfunction. Incorporating these evidence-based techniques into a simulation-based program for training nephrologists in NTHC insertion has been shown to be an effective way to improve the procedural skills of nephrology trainees. Nonetheless, there are some data suggesting nephrologists have been slow to adopt evidence-based practices surrounding NTHC insertion. This mini review focuses on techniques that reduce the complications of NTHCs and are relevant to the practice and training of nephrologists. PMID:24805107

    Full Text Available "nBackground: The annual amount of mortality in ESRD exceeds the expectation and represents the recent evidences of the inflammation as its etiology. The etiology of inflammation is not clearly known. Chronic inflammation is a dominant occurrence of ESRD which increases the risk of atherosclerosis, malnutrition and peripheral vascular disease. Inflammatory responses are orchestrated by cytokines. Some of the proinflammatory cytokines like IL-6 have a crucial role in this phenomenon. The IL-6 and its receptor activity is up regulated in ESRD patients and the increased level of IL-6 predicts cardiovascular mortality and morbidity in normal and CRF patients. This study devotes itself to determining the serum level of IL-6 and factors affecting it in patients undergoing chronic hemodialysis in Imam Khomeini Hospital which can represent the Iranian Society. By identifying factors affecting the serum level of IL-6 and high-risk patients we can provide treatment possibilities, a decrease in mortality and an improvement in its prognosis. "n"nMethods: In this study 42 patients in Imam Dialysis Center were chosen and their serum IL-6 levels were measured at 2 times at three month interval and at the same time blood sample analysis were done for the following: Alb CPR, Ca, P, PTH, TIBC, Ferritin, TG, Chol, LDL, HDL, Uric Acid, Hb, WBC and urea."n"nResults: The mean serum level of IL-6 in hemodialysis patients was 6.35±4.47pg/ml (minimum: 0.55, maximum: 18.25 with the normal range of 1.3±3.2pg/ml."n"nConclusions: The IL-6 level was higher than normal range in the 52% of the patients. The serum IL-6 level had a significant correlations with CPR, Ferritin, TIBC, WBC and their serum IL-6 level was significantly higher in patients with hypertension, but no significant correlation was observed between other parameters and IL-6

  10. Osteoarthropathy in long-term hemodialysis patients

    International Nuclear Information System (INIS)

    The authors reviewed hand and wrist films of 81 patients who had undergone hemodialysis for a minimum of 5 and a mean duration 7.5 years. The films of 32 patients showed arthritic changes consisting of articular erosions, joint space narrowings, periarticular cysts, and osteopenia. Five of these patients had subcutaneous or periarticular calcific deposits. The frequency and severity of the radiographic findings increased with increasing duration of dialysis. It appears that in addition to the well-recognized secondary hyperparathyroidism there is a second commonly occurring osteoarthropathy (40% in this series) related to long-term hemodialysis

    Because of its advantages, the transradial approach for cardiovascular interventions has gained significant popularity. However, this approach can be associated with radial artery thrombosis and occlusion. The complication generates a major concern for its potential impact on the future creation of an arteriovenous hemodialysis access. The issue gains more importance as a significant number of patients with cardiovascular disease suffer from underlying chronic kidney disease (CKD) and might need an arteriovenous access for hemodialysis therapy. In this context, the preservation of the arterial system is of equal importance to the frequently highlighted venous conservation for the successful creation of an arteriovenous access. It is for this reason that the Fistula First Breakthrough Initiative recommends avoiding the use of the radial artery for performing percutaneous interventions in patients with advanced CKD. Furthermore, there is scarce clinical data and publication regarding the impact of transradial approach on hemodialysis access. Is it possible to utilize the potential benefits and minimize the potential risks of transradial approach in chronic kidney disease patients? On the basis of current knowledge, this review discusses related issues of transradial approach to raise awareness and understanding, which are essential to proper caring of CKD patients undergoing cardiovascular interventions.

    Full Text Available End stage renal disease patients undergoing long-term dialysis are at risk for abnormal concentrations of certain essential and non-essential trace metals and high oxidative stress. We evaluated the effects of zinc (Zn supplementation on plasma aluminum (Al and selenium (Se concentrations and oxidative stress in chronic dialysis patients. Zn-deficient patients receiving continuous ambulatory peritoneal dialysis or hemodialysis were divided into two groups according to plasma Al concentrations (HA group, Al > 50 ?g/L; and MA group, Al > 30 to ? 50 ?g/L. All patients received daily oral Zn supplements for two months. Age- and gender-matched healthy individuals did not receive Zn supplement. Clinical variables were assessed before, at one month, and after the supplementation period. Compared with healthy subjects, patients had significantly lower baseline plasma Se concentrations and higher oxidative stress status. After two-month Zn treatment, these patients had higher plasma Zn and Se concentrations, reduced plasma Al concentrations and oxidative stress. Furthermore, increased plasma Zn concentrations were related to the concentrations of Al, Se, oxidative product malondialdehyde (MDA, and antioxidant enzyme superoxide dismutase activities. In conclusion, Zn supplementation ameliorates abnormally high plasma Al concentrations and oxidative stress and improves Se status in long-term dialysis patients.

    A photoacoustic (PA) spectrometer based on a near-IR tunable fiber laser is developed and used for breath ammonia analysis. We successfully measured the breath ammonia level variation of six patients with end-stage renal disease while they were undergoing hemodialysis in the hospital. The measurement results showed that the initial concentration level of the breath ammonia were from 1600 to 2200 ppb before dialysis treatment, the levels decreased to 200-600 ppb in the end stage of dialysis, which close to the levels of healthy persons. Further improvement and applications of this PA spectrometer are discussed.

    Full Text Available Objective: Patients undergoing hemodialysis are repeatedly exposed to stress and pain from approximately 300 punctures per year to their arteriovenous fistula. This study was designed to measure pain associated with venepuncture during AVF cannulation and to compare the effectiveness of ethyl chloride vapocoolant spray, topical eutectic mixture of local anesthetics (EMLA cream and placebo in controlling pain caused by venepuncture of arteriovenous fistula patients undergoing chronic hemodialysis.Methods: This randomized, placebo-controlled, crossover study, included 41 patients undergoing conventional hemodialysis three times a week. First intervention was conducted as baseline pain assessment (control. In the three consecutive dialysis sessions, every patient randomly received 1 ethyl chloride vapocoolant spray, 2 EMLA, or 3 placebo cream before venepuncture. Pain perception was recorded by patients immediately after cannulation on a 0-100 mm visual analogue scale (VAS. p<0.05 was considered as significant.Results: VAS scores presented a marked inter-individual variation during venepuncture. EMLA application resulted in significantly lower total pain scores compared to control and all other interventions (p<0.05. No patient experienced severe pain with EMLA or vapocoolant. The patients reported less moderate and severe pain with EMLA, and vapocoolant spray compared to control and placebo interventions. Moderate and severe pain scores were similar between EMLA and vapocoolant spray (p>0.05.Conclusion: Venipuncture for AVF cannulation causes mild to moderate pain in hemodialysis patients. Although local application of EMLA is more effective than in preventing venepuncture pain, ethyl chloride vapocoolant is as effective as EMLA for preventing mild to moderate puncture pain in patients undergoing hemodialysis.

    Full Text Available Although the revised dyadic adjustment scale (RDAS has been widely used as an indicator of the quality of marital relationship, no report is available on the reliability of this measure in patients on hemodialysis. We examined the internal consistency of the RDAS in a group of Iranian patients undergoing maintenance hemodialysis. A translated Persian version of the RDAS was self-administered to 135 patients. The internal consistency of the RDAS was tested using the Chronbach ? coefficient which was 0.898, 0.683, 0.779, 0.827, and 0.836 for the RDAS total score and the dyadic consensus, affective expression, dyadic satisfaction, and dyadic cohesion subdomains, respectively. All of the Chronbach ? scores were higher in patients with higher income and education level. Using the RDAS to examine marital relationship quality in patients on hemodialysis, the total score and almost all subscores except for dyadic consensus had adequate internal consistency.

Aim: To evaluate the effects of an exercise training program in patients undergoing chronic hemodialysis. Material [...] and Methods: Fifteen patients on chronic hemodialysis aged 21 to 69 years (three females) were included in the study. Nine of these were included in an exercise training program. During 16 weeks, exercise sessions were carried out during each dialytical procedure that included a warm-up period, aerobic exercises done using standing cycles, and resistance exercises, performed using Thera-Band® elastic bands and loops. Borg scale was used to control the intensity of training. At baseline and at the end of the study, a blood sample prior and after the dialytical procedure was obtained to measure C reactive protein, tumor necrosis factor ? and interleukin 6. Quadriceps muscle strength, six minutes´ walk and quality of life using the SF-36 questionnaire, were also measured. Results: Four experimental subjects did not complete the study period, two that withdrew before starting, one due to problems with the venous access and one that decided to withdraw after 1 month of training. Among the five patients that finished the training period, significant improvements in the six minutes´ walk and quadriceps strength were observed in the experimental group. No significant changes were observed among controls. No changes were observed in either group in C reactive protein, tumor necrosis factor and interleukin 6 levels or quality of life. Conclusions: Among patients undergoing chronic hemodialysis exercise training improves endurance and muscle strength.

We studied the prevalence of sleep disorders in 88 (mean age; 41.59 ± 16.3 years chronic hemodialysis (HD patients at the Urology and Nephrology Center, Mansoura Uni-versity, Egypt over 4-month period. The investigated sleep disorders included insomnia, restless leg syndrome (RLS, obstructive sleep apnea syndrome (OSAS, excessive daytime sleepiness (EDS, narcolepsy and sleep walking, and we used a questionnaire in accordance with those of the International Restless Legs Syndrome Study Group, the Berlin questionnaire, Italian version of Epworth Sleepiness Scale, International Classification of Sleep Disorders, and the specific ques-tions of Hatoum?s sleep questionnaire. The prevalence of sleep disorders was 79.5% in our pa-tients, and the most common sleep abnormality was insomnia (65.9%, followed by RLS (42%, OSAS (31.8%, snoring (27.3%, EDS (27.3%, narcolepsy (15.9%, and sleep walking (3.4%. Insomnia correlated with anemia (r=0.31, P= 0.003, anxiety (r=0.279, P= 0.042, depression (r=0.298, P= 0.24 and RLS (r=0.327, P= 0.002. Also, RLS correlated with hypoalbuminemia (r=0.41, P= < 0.0001, anemia (r=0.301 and P= 0.046, hyperphosphatemia (r=0.343 and P= 0.001. EDS correlated with OSAS (r=0.5, P= < 0.0001, snoring (r=0.341, P= 0.001, and social worry (r=0.27, P= 0.011. Sleep disorders are quite common in the HD patients, especially those who are anemic and hypoalbuminemic. Assessment of sleep quality, preferably with polysomno-graphy, is necessary to confirm our results. Interventional studies for management of sleep disor-ders in HD patients are warranted.

  6. Potential impact of renin-angiotensin system inhibitors and calcium channel blockers on plasma high-molecular-weight adiponectin levels in hemodialysis patients

    International Nuclear Information System (INIS)

    Although metabolic syndrome confers an increased risk of cardiovascular disease in the general population, little is known about the alteration of abdominal adiposity and its association with adipocytokines in hemodialysis patients. We investigated the plasma high-molecular-weight (HMW) adiponectin level and its relationship to visceral fat area (VFA) and various markers of atherosclerosis in hemodialysis patients. In a cross-sectional study, conventional cardiovascular risk factors, plasma total and HMW adiponectin, the number of components of the metabolic syndrome and, using computed tomography, the distribution of abdominal adiposity were assessed in 144 hemodialysis patients (90 men and 54 women; mean age, 60.7 years) and 30 age- and sex-matched patients with chronic kidney disease (CKD). Plasma HMW adiponectin levels in hemodialysis patients were significantly higher than those in patients with CKD, negatively associated with VFA and serum triglycerides and positively associated with plasma total adiponectin, as well as the HMW-to-total adiponectin ratio in men and women (all P<0.05) in a simple regression analysis. In a multiple regression analysis, VFA was a significant determinant of HMW adiponectin in hemodialysis patients. Furthermore, after adjustment for classical risk factors, HMW adiponectin levels were significantly higher in patients undergoing treatment with renin-angiotensin system inhibitors or calcium channel blockers compared with patients not unnel blockers compared with patients not undergoing such treatment. This study shows that plasma HMW adiponectin levels were negatively associated with VFA and positively associated with treatment with blockade of the renin-angiotensin system and of the calcium channel. Therefore, these drugs might be effective for improving adipocytokine-related metabolic abnormalities in hemodialysis patients. (author)

    Objective: The determine the frequency of erectile dysfunction in males on hemodialysis. Study Design: Descriptive study. Place and duration: Hemodialysis unit, Combined Military Hospital Kharian from October 2011 to April 2012. Patients and Methods: A total of 150 married male patients of end stage renal disease (ESRD) on hemodialysis were included in the study. Patients with cognitive and/or communication deficits and on hemodialysis for less than 06 months were excluded from the study. Erectile dysfunction (ED) was assessed using International Index of Erectile Function-5 (IIEF-5). Frequency of erectile dysfunction (ED) was analyzed using Statistical Package for Social Sciences (SPSS) version 17. Results: Mean age of the patients were 52.89 = 8.25 years. Mean duration of hemodialysis was 34 +- 9.62 months. The underlying etiology of end stage renal disease were diabetic nephropathy 69(46%), hypertensive nephropathy 51(34%), obstructive nephropathy 18(12%), glomerulonephritis 9(6%), autosomal polycystic kidney disease 3(2%). Mean IIEF-5 score was 13.29 +- 6.38. The frequency of erectile dysfunction was 74%. The majority of the patients, 73(48.7%) had moderate erectile dysfunction, while 24 (16%) had severe and 14 (9.3%) had mild erectile dysfunction. Out of total 150 patients enrolled, 39 (26%) patients had no erectile dysfunction. Conclusion: ED is a highly prevalent problem in men with ESRD. Physicians are urged to recognize the high prevalence of erection problems in men with ESRD and proactively question all patients regarding their sexual function. This will not only improve the recognition of this condition among these patients but also improve the quality of life after adequate treatment. (author)

  8. Thyroid hormone concentrations in dialysate during hemodialysis in children

    International Nuclear Information System (INIS)

    Thyroxine (T4) concentration in dialysate in the course of hemodialysis was determined in 15 children. Concentrations were measured by a modified radioimmunoassay. During hemodialysis there was a slight increase in T4 concentration. At the end of hemodialysis T4 concentration was about 50% higher than soon after the onset of hemodialysis. The loss of T4 into dialysate during hemodialysis was 19.2 ?g; the loss of T3 was less than 75 ng. The amount of the daily loss of thyroid hormones into dialysate was found to be in the range of normal urinary excretion. The lowering of serum thyroid hormone concentrations in children on hemodialysis cannot be explained by the loss of these hormones into dialysate. (orig.)

    INTRODUCTION: The aim of the study was to assess the validity and reliability of the SF-12 questionnaire in a sample of Iranian patients undergoing hemodialysis. MATERIALS AND METHODS: One hundred and forty-four hemodialysis patients were included from dialysis centers in Zanjan, Iran, and were asked to complete the SF-12 and SF-36 questionnaires. An initial test-retest reliability evaluation was performed on a sample of 70 patients from the total group, with a retest interval of 14 days. Reliability was estimated by internal consistency and validity was assessed using known-group comparisons and construct validity on the patient group as a whole. A linear regression analysis was used to assess any variation in the physical component summary and mental component summary scores of the SF-36 with the respective component summary scores of the SF-12. In addition, the factor structure of the questionnaire was extracted by performing a confirmatory factor analysis. RESULTS: Cronbach alpha for physicaland mental component summaries were 0.89 and 0.90, respectively. The SF-12 showed a good discriminatory ability between subgroups of patients based on demographic and clinical variables. The confirmatory factor analysis for the original two-factor structure showed a good fit index (chi2 = 23.30, degrees of freedom = 13), goodness-of-fit index = 0.96, and root mean squared error of approximation = 0.079). CONCLUSIONS: In general, the SF-12 has good psychometric properties and can be used as a shorter version of the SF-36 questionnaire in future studies involving Iranian patients undergoing hemodialysis.

    Both hemodialysis (HD) as well as peritoneal dialysis (PD), are efficient renal replacement therapies in uremic patients with and without diabetes. PD is less expensive dialysis modality and may provide a survival advantage over hemodialysis in first 2 to 4 years of treatment. Chronic ambulatory peritoneal dialysis (CAPD) as well as Continuous Cycler-Assisted Peritoneal Dialysis (CCPD) have additional advantages in patients with diabetes. PD therapy will be better tolerated than HD, the blood pressure is more stable and vascular access is not necessary. Preserving residual renal function (RRF) is of paramount importance to prolong the survival outcomes in PD patients. In insulin-dependent diabetic patients intraperitoneal insulin substitution can be used. The development of new, more biocompatible PD solutions holds promise for the future. Nevertheless, in many countries HD is further more favoured in the treatment of patients with ESRD. PMID:22971682

    Prior small studies have shown multiple benefits of frequent nocturnal hemodialysis compared to conventional three times per week treatments. To study this further, we randomized 87 patients to three times per week conventional hemodialysis or to nocturnal hemodialysis six times per week, all with single-use high-flux dialyzers. The 45 patients in the frequent nocturnal arm had a 1.82-fold higher mean weekly stdKt/V(urea), a 1.74-fold higher average number of treatments per week, and a 2.45-fold higher average weekly treatment time than the 42 patients in the conventional arm. We did not find a significant effect of nocturnal hemodialysis for either of the two coprimary outcomes (death or left ventricular mass (measured by MRI) with a hazard ratio of 0.68, or of death or RAND Physical Health Composite with a hazard ratio of 0.91). Possible explanations for the left ventricular mass result include limited sample size and patient characteristics. Secondary outcomes included cognitive performance, self-reported depression, laboratory markers of nutrition, mineral metabolism and anemia, blood pressure and rates of hospitalization, and vascular access interventions. Patients in the nocturnal arm had improved control of hyperphosphatemia and hypertension, but no significant benefit among the other main secondary outcomes. There was a trend for increased vascular access events in the nocturnal arm. Thus, we were unable to demonstrate a definitive benefit of more frequent nocturnal hemodialysis for either coprimary outcome. PMID:21775973

    Many studies found that hemoglobin (Hb) fluctuation was closely related to the prognosis of the maintenance hemodialysis patients. We investigated the association of factors relating dialysis dose and dialyzer membrane with Hb levels. We undertook a randomized clinical trial in 140 patients undergoing thrice-weekly dialysis and assigned patients randomly to a standard or high dose of dialysis; Hb level was measured every month for 12 months. In the standard-dose group, the mean (±SD) urea reduction ratio was 65.1%?±?7.3%, the single-pool Kt/V was 1.26?±?0.11, and the equilibrated Kt/V was 1.05?±?0.09; in the high-dose group, the values were 73.5%?±?8.7%, 1.68?±?0.15, and 1.47?±?0.11, respectively. The standard deviation (SD) and residual SD (liner regression of Hb) values of Hb were significantly higher in the standard-dose group and low-flux group. The percentage achievement of target Hb in the high-dose dialysis group and high-flux dialyzer group was significantly higher than the standard-dose group and low-flux group, respectively. Patients undergoing hemodialysis thrice weekly appear to have benefit from a higher dialysis dose than that recommended by current KDQQI (Kidney Disease Qutcome Quality Initiative) guidelines or from the use of a high-flux membrane, which is in favor of maintaining stable Hb levels.

    Background: This study was performed to investigate nutritional parameters of hemodialysis patients by using anthropometric and biochemical measurements. Methods: Data from the last 6 months of 22 adult hemodialysis patients with a mean age of 61 ± 14 years were analyzed retrospectively. Dialysis vintage, normalized protein catabolic rate (nPCR), serum biochemical parameters, mid arm muscle circumference (MAMC) were determined as mean and standard deviation. Correlations between the variables were computed by coefficient p of Pearson. Results: We found significant positive correlations: age of patients versus C-reactive protein, MAMC versus LDL-Cholesterol, MAMC versus body mass index, albumin versus hemoglobin. There were also significant negative correlations: age versus serum creatinine, age versus albumin, age versus intact parathyroid hormone (iPTH), dialysis vintage versus MAMC. Conclusion: In conclusion, age seem to be negatively associated with iPTH and albumin. As dialysis vintage increases, muscle mass seems to decrease. PMID:23935290

    After a diet and hydric restriction, travelling is one of the most limiting and worrying activities for patients under chronic renal replacement therapy. The vital dependency on the hemodialysis machine makes travelling an extremely difficult experience. In order to prove the legitimacy of our patients' fears, we embarked on to a cruise-liner with them. This confirmed their limitations when travelling thanks to the reliable data input. This study describes our personal and professional experience as nurses, specialized in hemodialysis, embarking onto a cruise-liner with twelve patients suffering from ESRD. Our goal is to share that experience with professional nurses as well as patients who seek information in regards to this type of trip with a specialized nurse. A summary of this work was presented as a communication oral in the XXXVI Congress of the Spanish Society of Nephrology Nursing. PMID:23815055

    Introduction End stage renal disease (ESRD) affects patient’s physical and psychological health. Depression is the most common psychiatric illness among patients with ESRD. This study aimed to identify the prevalence of depressive symptoms among patients undergoing peritoneal (PD) and hemodialysis (HD), also to correlate these symptoms with the demographic data. Methods this is a cross-sectional study that includes 133 PD patients and 133 HD patients attending the King Fahad Dialysis Center at King Saud Medical Complex (KSMC), Riyadh, Saudi Arabia. Socio-demographic data were documented. Depression was evaluated by using the zung self- rating depression scale (Zung SDS). Results using the Zung SDS; the prevalence of depression was significantly higher among PD patients (98.5%) in compare with HD patients (83.5%). Conclusion the study reveals that there is a high prevalence of depressive symptoms among PD and HD patients. This will lead us to think of adding a system for screening, diagnosis and treatment of depression for all dialysis patients to improve their life.

  1. Growing bone cysts in long-term hemodialysis

    International Nuclear Information System (INIS)

    All patients with chronic renal failure undergoing hemodialysis for more than 10 years in the university hospitals of Leuven were selected for this study. The medical records and radiographs of these 21 patients were studied retrospectively. Skeletal surveys were examined for the presence and location of subchondral cysts. The predialysis films and the films taken after 5, 10, 15 and 20 years of dialysis were reviewed. Subchondral cysts that grew in size and number were found in the wrist, humeral head, hip, and patella. Accurate measurements were made of cysts in the wrist and compared with a control group. In the dialysis group, cystic involvement of the wrist was more common and the size and number of the cysts were larger. Soft tissue swelling was seen in the dialysis group but not in controls. Soft tissue swelling was assessed on shoulder radiographs by measuring the acromiohumeral distance (ACD) and in the knees by ultrasonic measurement of synovial thickness. In 11 patients synovial or bone biopsies or aspirated synovial fluid were available. All these patients had swollen joints and multiple subchondral periarticular cysts. Amyloid deposition was found in ten of these patients, and this proved to be composed of B2 microglobulins in seven. (orig.)

    Uremic toxins are mainly represented by blood urine nitrogen (BUN) and creatinine (Crea) whose removal is critically important in hemodialysis (HD) for kidney disease. Patients undergoing HD have a complex illness, resulting from: inadequate removal of organic waste, dialysis-induced oxidative stress and membrane-induced inflammation. Here we report innovative breakthroughs for efficient and safe HD by using a plasmon-induced dialysate comprising Au nanoparticles (NPs)-treated (AuNT) water that is distinguishable from conventional deionized (DI) water. The diffusion coefficient of K3Fe(CN)6 in saline solution can be significantly increased from 2.76, to 4.62 × 10-6 cm s-1, by using AuNT water prepared under illumination by green light-emitting diodes (LED). In vitro HD experiments suggest that the treatment times for the removals of 70% BUN and Crea are reduced by 47 and 59%, respectively, using AuNT water instead of DI water in dialysate, while additionally suppressing NO release from lipopolysaccharide (LPS)-induced inflammatory cells.

Malnutrition-inflammation score (MIS, comprehensive nutritional assessment tool, as the reference standard was used to examine protein-energy wasting (PEW and inflammation in hemodialysis patients. Materials and Methods: In this descriptive- analytical study, 48 hemodialysis patients were selected with random sampling. All the patients were interviewed and the MIS of the patients was recorded. This new comprehensive Malnutrition-Inflammation Score (MIS which involves 7 components from the SGA and the 3 additional non-SGA components of body mass index, serum albumin, and total iron-binding capacity (TIBC has 10 components, each with four levels of severity, from 0 (normal to 3 (very severe. These scores were compared with anthropometric measurements; laboratory measures. Data was analyzed with Chi-square and t-tests and Pearson correlation coefficiant. Results: In this study 25% of patients on hemodialysis were normal nourished, 54.3% of patients were mild malnourished, 20.8% were moderately malnourished and no one of them were not sever malnurished. Pearson correlation coefficients between MIS score and age (r=+0.332 was significant. There was no correlation between the malnutrition score and sex Chi-square test showed significant correlation between MIS score and dialysis period ?50 months (?²=9.09. Conclusion: In this study, no one of patients has severed malnutrition, and most of them were assigned to the mildly/moderately malnourished rating. On other hand, most of patients are the well-nourished. Correlation between MIS score and age and dialysis period was significant.

    Full Text Available Rabih Nasr,1 Chadi Saifan,1 Iskandar Barakat,2 Yorg Al Azzi,2 Ali Naboush,2 Marc Saad,2 Suzanne El Sayegh1 1Department of Nephrology, Staten Island University Hospital, Staten Island, NY, USA; 2Department of Medicine, Staten Island University Hospital, Staten Island, NY, USA Background: One factor associated with poor outcomes in hemodialysis patients is exposure to a foreign membrane. Older membranes are very bioincompatible and increase complement activation, cause leukocytosis by activating circulating factors, which sequesters leukocytes in the lungs, and activates platelets. Recently, newer membranes have been developed that were designed to be more biocompatible. We tested if the different “optiflux” hemodialysis membranes had different effects on platelet levels. Methods: Ninety-nine maintenance hemodialysis patients with no known systemic or hematologic diseases affecting their platelets had blood drawn immediately prior to, 90 minutes into, and immediately following their first hemodialysis session of the week. All patients were dialyzed using a Fresenius Medical Care Optiflux polysulfone membrane F160, F180, or F200 (polysulfone synthetic dialyzer membranes, 1.6 m2, 1.8 m2, and 2.0 m2 surface area, respectively, electron beam sterilized. Platelet counts were measured from each sample by analysis using a CBC analyzer. Results: The average age of the patients was 62.7 years; 36 were female and 63 were male. The mean platelet count pre, mid, and post dialysis was 193 (standard deviation ±74.86, 191 (standard deviation ±74.67, and 197 (standard deviation ±79.34 thousand/mm3, respectively, with no statistical differences. Conclusion: Newer membranes have no significant effect on platelet count. This suggests that they are, in fact, more biocompatible than their predecessors and may explain their association with increased survival.

    At the beginning of the 1980s, nutritional status appeared as a key element of quality of life, health care requirements, and survival during chronic renal failure. In patients on dialysis, malnutrition is a major determinant of survival, and its management appears to be a key element in terms of outcome. Recommendations for the nutritional management of patients on hemodialysis have been elaborated by the National Kidney Foundation (NKF) and the European Society of Parenteral and Enteral Nutrition (ESPEN).

We report a case of infection of an implanted polytetrafluoroethylene dialysis graft with Fusarium incarnatum/equiseti that did not grow in cultures of tissue but was identified by molecular means.

    Full Text Available   "nThe basic concept of hemodialysis access is to make a route to the central circulation in CRF patients. Vascular access procedures and subsequent complications represent a major cause of morbidity, hospitalization and cost for hemodialysis patients. Native arteriovenous fistulas (AVFs are preferable to synthetic arteriovenous grafts because they are associated with a lower frequency of thrombosis and infection, as well as greater longevity. AVFs that are never usable and early graft failures are associated with the common problem of inadequate vessel (artery or vein selection. The surgeon’s preoperative physical examination is the primary basis for AVF versus graft selection. Only palpable veins are considered for construction of AVFs, and the more proximal draining venous anatomy is not known prior to the operation. Physical examination is the traditional surgical evaluation performed prior to hemodialysis access placement. Palpation and inspection are difficult in obese arms, and few patients have vessels that are visible throughout their entire course. Patients with end-stage renal disease have often had multiple venipunctures and numerous intravenous lines placed and thus have an increased likelihood of venous stenosis or occlusion. Central vein problems are difficult to detect at visual inspection. By colour Doppler analysis vessels can be assessed for size, stenosis, and occlusion. US mapping assists in surgical planning and is especially valuable in patients who are difficult surgical cases (eg, obesity, diabetes, history of prior access, elderly women.  "nThis lecture contains two separate sections: 1-Vascular mapping prior to access placement and 2-Fistula maturity by US evaluation. Ultrasonography (US is an excellent modality for hemodialysis access evaluation because it is  readily available, non-invasive and inexpensive. It avoids the risks associated with iodinated contrast material and ionizing radiation.

    The use of dialysis in patients with end-stage renal disease (ESRD) remains one of the most resource-intensive and hence, expensive therapeutic interventions. The purpose of this study was to assess the cost of hemodialysis (HD) in Iran. This study was conducted in the Department of Nephrology at the Imam Khomeini Hospital of Tehran University of Medical Sciences, Iran, between April 2006 and June 2007. Patients with ESRD on chronic HD were involved in the study. Relevant data were collected ...

  14. Computed tomography of kidneys with hemodialysis

    International Nuclear Information System (INIS)

    Computed tomography (CT) of the kidneys was carried out in 134 chronic intermittent hemodialysis patients. A high incidence of cysts, calcification and tumor was found. The absorption value (Hounsfield units) of renal parenchyma, excluding visible cysts and calcification on CT, showed a very wide scatter compared to the controls. A low absorption value indicated a cyst too small to define by CT imaging of the excised kidney. Two of three adenocarcinomas were found by CT screening in sympton-free dialysis patients. (author)

    Little information is available on the impact of hemodialysis on cerebral water homeostasis and its distribution in chronic kidney disease. We used a neuropsychological test battery, structural magnetic resonance imaging (MRI) and a novel technique for quantitative measurement of localized water content using 3T MRI to investigate ten hemodialysis patients (HD) on a dialysis-free day and after hemodialysis (2.4±2.2 hours), and a matched healthy control group with the same time interval. Neuropsychological testing revealed mainly attentional and executive cognitive dysfunction in HD. Voxel-based-morphometry showed only marginal alterations in the right inferior medial temporal lobe white matter in HD compared to controls. Marked increases in global brain water content were found in the white matter, specifically in parietal areas, in HD patients compared to controls. Although the global water content in the gray matter did not differ between the two groups, regional increases of brain water content in particular in parieto-temporal gray matter areas were observed in HD patients. No relevant brain hydration changes were revealed before and after hemodialysis. Whereas longer duration of dialysis vintage was associated with increased water content in parieto-temporal-occipital regions, lower intradialytic weight changes were negatively correlated with brain water content in these areas in HD patients. Worse cognitive performance on an attention task correlated with increased hydration in frontal white matter. In conclusion, long-term HD is associated with altered brain tissue water homeostasis mainly in parietal white matter regions, whereas the attentional domain in the cognitive dysfunction profile in HD could be linked to increased frontal white matter water content.

    Understanding the toxicity of certain potentially toxic compounds on various aquatic organisms allows to assess the impact that these pollutants on the aquatic biota. One source of pollution is the wastewater from hemodialysis. The process of sewage treatment is inefficient in inhibition and removal of pathogenic bacteria resistant to antibiotics in this wastewater. In many countries, such as Brazil, during emergencies, sewage and effluents from hospitals are often dumped directly into waterways without any previous treatment. The objective of this study was to characterize the effluents generated by hemodialysis and to assess the degree of acute and chronic environmental toxicity. The effluents of hemodialysis showed high concentrations of nitrites, phosphates, sulfates, ammonia, and total nitrogen, as well as elevated conductivity, turbidity, salinity, biochemical and chemical oxygen demand, exceeding the thresholds defined in the CONAMA Resolution 430. The samples showed acute toxicity to the green flagellate Euglena gracilis affecting different physiological parameters used as endpoints in an automatic bioassay such as motility, precision of gravitational orientation (r-value), compactness, upward movement, and alignment, with mean EC50 values of recalculate as 76.90 percent (±4.68 percent) of the undiluted effluents. In tests with Daphnia magna, the acute toxicity EC50 was 86.91 percent (±0.39 percent) and a NOEC value of 72.97 percent and a LEOC value 94.66 percent. PMID:24580820

    2009-05-01

    Home hemodialysis, once a valid, viable dialysis choice, faded as facility-based care was preferentially funded and supported through the 1970s and 1980s. It was simply more comfortable for providers, physicians, and nurses to capture dialysis patients through clinic schedules and clinical protocols. Home patients were unpredictable, out of sight and out of control, trouble, and best avoided. This was so except in Australia and New Zealand where funding and support remained strong for what was seen there as an effective, outcome-rich, and cost-effective modality. The renaissance of home hemodialysis began in Canada when home-based nocturnal dialysis emerged in the 1990s. Home patients soon appreciated the self-determination and re-employment opportunities that overnight dialysis delivered. This article explores the origins, the near demise, the foundations of renewal, and the now-expanding potential of home and nocturnal hemodialysis in regions as diverse as North America, Australia and New Zealand, South East Asia, the United Kingdom, and Finland. Home dialysis fed by cost containment, outcome success, patient acceptance, and new smart equipment has emerged as a bright new modality option. Trainee nephrologists would be wise to take more notice as this near ghost of the past forges an exciting future. PMID:19393971

    In patients with chronic renal failure, not yet undergoing hemodialysis (HD), plasma acylcarnitines accumulate in part due to a decreased renal clearance of esterified carnitine moieties. In these patients, a high acylcarnitine/free-carnitine ratio is usually found in plasma. Patients undergoing maintenance HD, usually present with plasma carnitine insufficiency, due to accumulation of metabolic intermediates combined with impaired carnitine biosynthesis, reduced protein intake and increased removal via HD. Plasma carnitine concentrations rapidly decrease to 40% of baseline level during the dialysis session, with a slow restoration of the carnitine concentration during the interdialytic period, mainly from organs of storage (skeletal muscle). Dietary intake also plays an important role in carnitine homeostasis of HD patients since the prevalence of malnutrition ranges from 18% to 75% of these cases. This could differentially affect various body compartments, with clinical consequences such as impaired muscle function, decreased wound healing, altered ventilatory response, and abnormal immune function. Repeated hemodialytic treatments are associated with decreased carnitine stores in skeletal muscle. The administration of intravenous L-carnitine (LC) postdialysis replenishes the free carnitine removed from the blood and contributes to replenishment of muscle carnitine content. LC supplementation in selected uremic patients may yield clinical benefits by ameliorating several conditions, such as erythropoietin-resistant anemia, decreased cardiac performance, intradialytic hypotension, muscle symptoms, as well as impaired exercise and functional capacities. Furthermore, LC may positively influence the nutritional status of HD patients by promoting a positive protein balance, and by reducing insulin resistance and chronic inflammation, possibly through an effect on leptin resistance.

    Purpose: We evaluated the safety of a gadolinium (Gd) contrast agent in hemodialysis patients. Material and Methods: Seventy hemodialysis patients underwent contrast-enhanced MR examination. After the examination, the patients were hemodialyzed on a usual schedule, i.e., 3 times per week at 4 h each session. The hemodialysis was performed on the same day in 16 patients, the next day in 34, 2 days later in 14 and 3 days later in 6 patients. Serum Gd concentrations before and after the first to fourth hemodialysis sessions were analyzed in 11 patients. Cardiovascular, cutaneous, respiratory, psycho-neurological and digestive side effects were evaluated in all patients. Changes in liver and kidney functions, blood counts, and electrolytes were also checked. Results and Conclusion: Neither side effects nor blood changes were noted in any of the patients. Average excretory rates were 78.2%, 95.6%, 98.7% and 99.5% in the first to fourth hemodialysis sessions, respectively. These results suggest that Gd contrast agents can be used in hemodialysis patients if hemodialysis is carried out promptly after the examination. Key words: Renal failure, hemodialysis; contrast agent, gadolinium.

    Full Text Available (Received 23 Jul, 2008 ; Accepted 12 Nov, 2008AbstractBackground and purpose: Pruritus is one of the common problems in hemodialysis patients with end stage renal disease. Approximately, 60% of these patients suffer from this condition. There are several causes for pruritus, thus, various treatments are applied in order to control it. The aim of this study was to evaluate the therapeutic effect of capsaicin on pruritus, compared with placebo, in hemodialysis patients.Materials and methods: This randomized double blind cross over clinical trial study, was performed on 34 hemodialysis patients with uremic pruritus in 1386. All patients were divided in two groups. One group received Caspian 0.03%, while the other, placebo for four weeks. Treatment was stopped for two weeks and continued as cross over technique. Pruritus scores were analyzed with Paired t-test and Repeated measurement ANOVA.Results: In this study, the difference between Mean of pruritus score before capsian treatment and in weeks following 1 to 4 was statistically significant (P=0.0001. In placebo group, the difference between pruritus score before treatment and in weeks 1 to 4 was statistically significant (P=0.0001. There was no significant difference before treatment in two groups, however, after each week, the difference was significant (P=0.0001. Repeated measurement test showed that reduction in pruritus severity in capsian group was more than placebo group, during treatment period (P=0.0001.Conclusion: Although our study indicated the appropriate effects of Capsian in pruritus, the placebo also has a good effect in controlling hemodialysis related pruritus. Our placebo had emollient property; therefore, we can apply it to control the pruritus in these patients.J Mazand Univ Med Sci 2009; 19(69: 7-13 (Persian

    Full Text Available End-stage renal disease (ESRD) patients frequently develop structural cardiac abnormalities, particularly left ventricular hypertrophy (LVH). The mechanisms involved in these processes are not completely understood. In the present study, we evaluated a possible association between parathyroid hormon [...] e (PTH) levels and left ventricular mass (LVM) in patients with ESRD. Stable uremic patients on intermittent hemodialysis treatment were evaluated by standard two-dimensional echocardiography and their sera were analyzed for intact PTH. Forty-one patients (mean age 45 years, range 18 to 61 years), 61% males, who had been on hemodialysis for 3 to 186 months, were evaluated. Patients were stratified into 3 groups according to serum PTH: low levels (280 pg/ml; group III = 21 patients). A positive statistically significant association between LVM index and PTH was identified (r = 0.34; P = 0.03, Pearson's correlation coefficient) in the sample as a whole. In subgroup analyses, we did not observe significant associations in the low and intermediate PTH groups; nevertheless, PTH and LVM index were correlated in patients with high PTH levels (r = 0.62; P = 0.003). LVM index was also inversely associated with hemoglobin (r = -0.34; P = 0.03). In multivariate analysis, after adjustment for age, hemoglobin, body mass index, and blood pressure, the only independent predictor of LVM index was PTH level. Therefore, PTH is an independent predictor of LVH in patients undergoing chronic hemodialysis. Secondary hyperparathyroidism may contribute to the elevated cardiovascular morbidity associated with LVH in ESRD.

  7. 320-row computed tomography coronary artery screening in the beginning period of maintenance hemodialysis

    International Nuclear Information System (INIS)

    Sixty-one patients at this hospital have been undergoing outpatient hemodialysis for 80 years of age, 10 who underwent conventional coronary angiography (CAG), and 13 who did not consent to participation in this study. Among the 32 patients, CT imaging demonstrated that 6 had coronary stenosis, and 20 did not have coronary stenosis. The remaining 6 patients were indeterminate (5, advanced calcification; 1, poor image quality). The average age of patients with coronary stenosis (67.3±9.5 years) and indeterminate cases (68.3±9.7 years) was significantly higher (p<0.05 and p<0.01, respectively) than that of those without coronary stenosis (54.0±11.8 years). The calcification score of indeterminate cases (1088±907) was significantly higher (p<0.05 and p<0.01, respectively) than that of patients with (351±356) or without (100±217) coronary stenosis. Four of the 6 coronary stenosis patients also had diabetes (67%), which was higher than the rate of 5/20 patients without coronary stenosis (25%), but the difference was not significant. Five of 6 patients with CT-detected coronary stenosis who underwent CAG had significant stenosis requiring treatment. One patient underwent coronary artery bypass surgery, 2 percutaneous coronary intervention (PCI), and the other 2 were ation (PCI), and the other 2 were administered drugs. One of 5/6 patients who were indeterminate on CT was found to have significant coronary artery stenosis, and PCI was performed. CT coronary artery screening detected coronary artery disease requiring treatment in 6/32 (19%) asymptomatic hemodialysis patients, on whom CAG was performed. Since 320-row CT coronary artery screening can detect untreated and latent coronary stenosis, it is useful to screen patients at the initiation of maintenance hemodialysis. (author)

    The dialysis machine shall be cleaned and disinfected after each patient treatment or after every 72 hours break in working. An acceptable disinfectants such as Puristeril plus or Puristeril 340, Citrosteril, Diasteril and Sporotal are used for decontamination. Puristeril 340 is designed for cold disinfection and due to the low pH value, the necessary decalcification of hemodialysis machines is easily achieved. It can be used for all haemodialysis systems like hemodialysis machines, water treatment devices and circuit pipes. Diluted Puristeril decomposes in a non-toxic way. Degradation products of peracetic acid, which is main component of Puristeril are: hydrogen peroxide and acetic acid. Peracetic acid is widely used for disinfection due to its exceptionally broad spectrum of microbiocidal activity at low concentrations and short exposure times. After use Puristeril is easily removable by rinsing with water. This paper deals with the effect of the Puristeril toxicity on blood as a function of its concentration and incubation time. Concentration range of 3.5-70 ppm was used, with particular emphasis on concentrations close to 5 ppm, a value is the limit of sensitivity of strips of starch potassium iodide, the tests for detection of peracetic acid. There was a strong increase in autohaemolysis and malondialdehyde concentrations with increasing concentration of Puristeril. There were also changes in dependence on the parameters of the incubation time, with the greatest effects obtained after 2 hours incubation with Puristeril. The detection limit of peracetic acid used strips of starch potassium iodide does not guarantee the safety of a patient undergoing hemodialysis. Even the residual concentration of Puristeril plus cause increased lipid peroxidation of membrane, and therefore suggest the routine use of stripes on the lower limit of detection of peracetic acid or implement measurement of hydrogen peroxide residues performed with sensitivity 1 ppm.

    Background and Objectives. There is no data analyzing the outcome of blood transfusions and oral iron therapy in patients with kidneys failure in sub-Saharan Africa. The present study aimed to fill that gap and assess the value of ferritin in the diagnosis of iron overload and deficiency. Design. From January to February 2012, we prospectively studied 85 hemodialysis patients (78% of males and 22% of females aged 20 to 79 years) attending the Gabonese National Hemodialysis Centre. Results. Correlation studies showed (a) a strong positive linear relationship between the number of blood transfusions and high serum ferritin in hemodialysis patient (Spearman r : 0.74; P value: 0.0001); (b) a weak association between the number of blood transfusions and serum iron concentrations (Spearman r : 0.32; P value: 0.04); (c) a weak association between serum ferritin and serum iron (Spearman r : 0.32; P value: 0.003). Also, the strength of agreement beyond chance between the levels of ferritin and iron in the serum was poor (? = 0.14). The prevalence of iron overload was 10.6%, whereas the prevalence of iron deficiency was 2.3%, comparing (1) patients with a maximum of one transfusion not on iron therapy; (2) patients with a maximum of one transfusion on iron therapy; (3) polytransfused patients not on iron therapy; and (4) polytransfused patients on oral iron therapy. The “Kruskal-Wallis test” showed that ferritin levels varied significantly between the groups (P value: 0.0001). Conclusion. Serum ferritin is not reliable as a marker of iron overload. For patients undergoing regular transfusion we recommend routine serum ferritin measurement and yearly measurement of LIC. PMID:25685597

  10. Radiologic placement of hemodialysis central venous catheters: a practical guide

    International Nuclear Information System (INIS)

    Typical indications for central venous catheters (CVCs) are hemodialysis (HD), apheresis, total parenteral nutrition, analgesia, chemotherapy, long-term antibiotic therapy and cases of difficult or absent peripheral venous access. One of the largest medical services requesting CVC insertion is nephrology for HD patients. Demographics dictate that the demand for CVCs will continue to grow over the next few decades, placing striking demands on interventional radiology departments. In our centre, interventional radiologists now place nearly all percutaneously inserted HD CVCs. Radiologists provide rapid access to CVC services with significantly fewer complications than CVCs placed by other clinicians. With the demand for CVC management increasing and available operating room time decreasing, many clinicians now refer CVC insertions to radiologists. As well, clinicians who ordinarily place their own lines often refer high-risk patients, such as those who are obese or uncooperative and those with burns or coagulopathy. Our experience, derived from over 7000 CVC insertions, manipulations and removals, has allowed us to continually progress and improve our techniques, many of which are summarized here. (author)

    Full Text Available Objective: The restless legs syndrome (RLS is characterized by unpleasant sensations and pain in the legs, irresistible urge to move the legs, especially when resting and often accompanied by sleep disorders. RLS prevalence is up to 80% in hemodialysis patients. It is such an important clinical condition that is associated with increased mortality. Moreover etiopathogenesis is not clear. We aimed to evaluate vascular disorders, heart rate variability, oxidative stress parameter in hemodialysis patients with RLS. Material and Methods: Study was conducted with hemodialysis patients. Twenty five patients diagnosed as RLS with International Restless Legs Study Group criteria, and twenty five patients without RLS (control group were included to the study. Patients were examined with complete blood count and biochemical assays, Kt/V, oxidative stress parameter such as malon dialdehyde and sulphydryl, lower extremity Doppler ultrasonography and 24 hour holter heart rate variability. Results: Patients with RLS had significantly lower hemoglobin and sodium levels (p:0.025 ve p:0.038. Tibialis posterior and anterior artery ?ow was significantly reduced in patients with RLS (p:0.011 ve p:0.010. There was significant correlation about low hemoglobin and sodium level and reduced tibialis posterior and anterior artery ?ow. With logistic regression analysis, only hemoglobin was determined as independent factor on RLS (OR 6.211 [%95 CI 1.368-26.176] p=0.018. Conclusion: It is concluded that hemoglobin is an important independent factor for progression to RLS. Therefore hemoglobin level must be maintained in normal range especially in patients with RLS.

    Full Text Available Factors associated with physical well being were examined in adults with end-stage renal disease (ESRD in two large hemodialysis units of the Royal Medical Services in Jordan. Utilizing the Karnofski scale we measured the functional status of 200 Patients who had been on maintenance hemodialysis for at least 12 months. A Marnofski scale of less than 70 incidents frank disability (Inability to perform routine living activities without assistance, in addition current vocational status was assessed as well as any existing comorbid conditions. The mean age of the study group was 45.2 years (range 16 to 70 and included 108 (54% males and 92 (46% females, there were 39 (19.5% diabetic patients and 27 (13.5% patients were receiving erythropoietin (EPO. The mean hematocrit of the entire group was 27.8%. As measured by Karnofski scale, 64 (32% of the patients were unable to perform routine living activity without assistance; dependence on wheelchair was reported by 9 (4.5% patients. The mean comorbidity index of patients who scored less than 70 on the Karnofski scale was 1.5 compared to 0.7 for those who scored at least 70 on the same scale (p< 0.001. Analysis of factors showed that age and diabetes mellitus affected functional status. Of the laboratory variables measured, only serum albumin concentration correlated significant with Karnofski scale. Fourteen (21.8% of the patients who scored below 70, had serum albumin concentration above 40g/L compared to 66 (48.5% of the patients who scored at least 70 on the Karnofski scale (p< 0.001. We conclude that a significant proportion of patients on maintenance hemodialysis is functionally disabled. The elderly, diabetics, patients with high co-morbidity index and those with low serum albumin are most likely to have poor functional status.

    Digitoxin is considered a risk factor for ventricular arrhythmias in hemodialysis patients. In a randomized, crossover controlled study, 55 hemodialysis outpatients with sinus rhythm were prospectively investigated in two 48-h periods of electrocardiographic monitoring, one on and one off digitoxin or vice versa. The frequency of ventricular ectopic beats (mean +/- SD) which were found in 31 of 55 patients (56%), was slightly higher on hemodialysis (10 +/- 28 beats/h) than in the following 20 h (5.4 +/- 10 beats/h) and the next day off hemodialysis (3.6 +/- 6.6 beats/h); however, no difference was seen in patients on digitoxin during hemodialysis (10 +/- 29 beats/h), in the following 20 h (4.8 +/- 15 beats/h) and on the next day off hemodialysis (1.2 +/- 6.6 beats/h). The frequency of ventricular bigemini, polymorphous ectopies, couplets, more than 30 ectopies/h, salvos and tachycardias (10 vs 9 patients) on and off digitoxin was about the same (n.s., Fisher test). Supraventricular bigemini, salvos, tachycardias, and atrial fibrillation, however, occurred in significantly fewer patients on digitoxin (3 vs 13) than in those off digitoxin (P = 0.01, Fisher test). It is concluded that digitoxin does not increase the risk of ventricular arrhythmias in hemodialysis patients. Digitoxin, however, may have a beneficial effect on the supraventricular arrhythmias frequently observed in these patients. PMID:2447325

    Full Text Available Objective: Brain-derived neurotrophic factor (BDNF is a neurotrophin which modulates neuronal survival and proliferation. Recently, plasma BDNF is associated with inflammatory conditions. The present study was to investigate the changes of the plasma BDNF level in hemodialysis patients and to evaluate the relationship between the plasma BDNF and uremic inflammation.Method: We measured the plasma BDNF, serum IL-2, IL-4, IFN-? and TNF-? in hemodialysis patients and control subjects. In addition, we investigated the associations of the plasma BDNF with clinical or biochemical parameters.Results: The plasma BDNF level was significantly higher in hemodialysis patients than in the control subjects (median, 312.3 vs. 630.3 pg/ml, p < 0.05. In subgroup analysis, hemodialysis patients with diabetes showed higher values of the plasma BDNF than the patients without diabetes. However, there were no significant differences in age and gender subgroups of the hemodialysis patients. The logBDNF was positively correlated with hs-CRP and IFN-?, and negatively correlated with serum albumin. In multivariate regression analysis, the logBDNF was independently associated with the presence of diabetes (?-coefficient = 0.399, p = 0.041 and IFN-? (?-coefficient = 0.538, p = 0.003.Conclusion: The plasma BDNF may increase in hemodialysis patients, and more prominently in the patients with diabetes. Furthermore, the plasma BDNF might reflect inflammatory condition in hemodialysis patients.

    Over the past decades, evidence on the benefits of intensive hemodialysis, more frequent and longer comparing to conventional hemodialysis, has emerged. The home environment is an ideal setting to perform intensive hemodialysis without the reliance on organizational and structural needs. The observed benefits of frequent hemodialysis have resulted in a rise in prevalent intensive home hemodialysis patients around the world. A successful home hemodialysis program requires a well-structured predialysis education program with focus on home dialysis and a dedicated multidisciplinary team with knowledge about the specifics of home hemodialysis and with a holistic approach to provide optimal care. In this narrative review, we describe different modalities of home hemodialysis and dialysis prescription specifics of intensive nocturnal hemodialysis, the modality with overall best outcomes.

    For end-stage renal disease patients undergoing hemodialysis, thrombosis caused by stenosis hinders the long-term use of vascular access. However, traditional spectral bruit analysis techniques for detecting the severity of vascular access stenosis are not robust. Accordingly, the present study proposes an automated method for mimicking a trained practitioner in performing the auscultation process. In the proposed approach, the bruit obtained using a standard phonoangiographic method is transformed into the time-frequency domain, and two spectro-temporal features, namely the auditory spectrum flux and the auditory spectral centroid, are then extracted. The distributions of the two features are analyzed using a multivariate Gaussian distribution (MGD) model. Finally, the distribution parameters of the MGD model are used to detect the presence (or otherwise) of vascular access stenosis. The validity of the proposed approach is investigated using the phonoangiography signals obtained from 16 hemodialysis patients with straight arteriovenous grafts over the upper arm region. The results show that the MGD covariance matrix coefficient of the auditory spectral centroid feature yields an accuracy of 83.87 % in detecting significant vascular access stenosis. Thus, the proposed method has significant potential for the applications of vascular access stenosis detection. PMID:25681949

    A growing number of studies have demonstrated the importance of marital quality among patients undergoing medical procedures. The aim of the study was to expand the literature by examining the relationships between stress, social support and family and marriage life among hemodialysis patients. A total of 114 participants, including 38 patients and their spouses and 38 healthy controls, completed a survey package assessing social support, stress, family functioning and marital satisfaction and quality. We found that hemodialysis patients and spouses were less flexible in family adaptability compared with the healthy controls. Patients and spouses had more stress and instrumental social support compared with healthy people. Stress was negatively associated with marital satisfaction. Instrumental support was not associated with family or marital outcomes. The association between marital quality and support outside of family was positive in healthy individuals but was negative in patients and their spouses. Family adaptability was positively associated with support within family as perceived by patients and positively associated with emotional support as perceived by spouses. In conclusion, findings suggest that social support may promote adjustment depending on the source and type. Future research should pay more attention to the types and sources of social support in studying married couples. Copyright © 2014 John Wiley & Sons, Ltd. PMID:24470353

    Leptin, the gene product of the ob gene, is important in the control of appetite in rodents and may have an important role in humans. The clearance of leptin from the circulation is unknown. As the leptin receptor is present in the kidney, we evaluated the role of the kidney in removing circulating leptin in humans. We measured leptin in aortic and renal vein plasma in 8 patients with intact renal function and 6 patients with impaired renal function who were undergoing elective cardiac catheterization. Renal blood flow was measured in all patients to calculate net mass balance across the kidney. In patients with intact renal function there is net renal uptake of 12% of circulating leptin, whereas in patients with renal insufficiency there is no renal uptake of leptin. In a separate cohort of 36 patients with end-stage renal failure on hemodialysis, peripheral leptin levels factored for body mass index was increased by > fourfold as compared to a group of healthy controls (N = 338). In addition, plasma leptin is not cleared by hemodialysis with a modified cellulose membrane. Additional studies are required to evaluate the role of leptin in mediating the anorexia of uremia.

    Full Text Available Abstract Background Visceral adipose tissue-derived serine proteinase inhibitor (vaspin is an adipokine identified in genetically obese rats that correlates with insulin resistance and obesity in humans. Recently, we found that 7% of the Japanese population with the minor allele sequence (A of rs77060950 exhibit higher levels of serum vaspin. We therefore evaluated the serum vaspin levels in Japanese chronic hemodialysis patients. Methods Healthy Japanese control volunteers (control; n?=?95, 49.9±6.91?years and Japanese patients undergoing hemodialysis therapy (HD; n?=?138, 51.4±10.5?years were enrolled in this study, and serum samples were subjected to the human vaspin RIA system. Results The measurement of the serum vaspin levels demonstrated that a fraction of control subjects (n?=?5 and HD patients (n?=?11 exhibited much higher levels (> 10?ng/ml; VaspinHigh group, while the rest of the population exhibited lower levels (Low group. By comparing the patients in the VaspinLow group, the serum vaspin levels were found to be significantly higher in the control subjects (0.87±0.24?ng/ml than in the HD patients (0.32±0.15?ng/ml (p? Conclusions The creatinine levels are negatively correlated with the serum vaspin levels and were significantly reduced in the Japanese HD patients in the VaspinLow group.

    Because pregnancy is rare in women with end-stage renal disease, dialysis patients have not been reported to present with acute abdominal symptoms related to pregnancy including ectopic pregnancy. A 41-year-old woman treated with hemodialysis for over 18 years was brought to the emergency room at our institution because of acute abdominal pain. Ultrasonography detected an abdominal fluid collection, and her anemia had worsened (hematocrit 18%). Emergency laparoscopic exploration disclosed a hemorrhagic corpus luteum of pregnancy, causing ovarian bleeding on the left. Coagulation of bleeding points was carried out. At this time, pregnancy at 7 weeks of gestation was discovered. After the procedures, hemodialysis frequency was increased to 5 times weekly, and an erythropoietin derivative was administered to maintain a hematocrit above 30%. The patient developed no hypertension. At 33 weeks of gestation, cesarean section was performed because of a decrease in amniotic fluid and frequent late deceleration of the fetal heart rate. A live baby girl weighing 1,422 g was born. The successful pregnancy reflects remarkable progress in dialysis technology. Pregnancy, then, can underlie an acute abdomen in childbearing-age women (14 - 44 years old) undergoing long-term dialysis. PMID:19281751

  5. Amyloid arthropathy of the hip joint: MR demonstration of presumed amyloid lesions in 152 patients with long-term hemodialysis

    International Nuclear Information System (INIS)

    The aim of this study was to determine the spectrum of MR findings of presumed amyloid arthropathy of the hip joints in patients on long-term hemodialysis. We prospectively performed T1- and T2-weighted spin-echo imaging on 152 consecutive patients on hemodialysis. The duration of hemodialysis ranged from 5 months to 24 years, 2 months (mean: 8 years, 8 months). The frequency, location, and signal intensity of bone lesions were assessed. In 12 cases with contrast-enhanced MR examination, enhancement pattern of bone lesions, synovial lesions, and intra-articular lesions were characterized. Bone lesions presumed to be amyloid deposits were identified in 60 patients (39 %). Magnetic resonance imaging revealed that amyloid lesions were more extensive than anticipated by plain radiographs. All bone lesions showed decreased signal intensity on T1-weighted images. On T2-weighted images, bone lesions showed increased signal intensity in 32 patients (54 %), decreased signal intensity in 11 patients (18 %), and both increased and decreased signal intensity in 17 patients (28 %). Following intravenous injection of gadolinium-based contrast, all bone lesions showed moderate enhancement. Synovial thickening could not be identified on T1- and T2-weighted images. However, contrast-enhanced images showed thickened synovial membrane, which could be differentiated from joint fluid. Intra-articular nodules showed decreased or intermediate signal intensity on T1-weighted images and decre intensity on T1-weighted images and decreased signal intensity on T2-weighted images; the intra-articular nodules were contiguous with subchondral bone lesions. Magnetic resonance imaging is useful for evaluating the distribution and extent of amyloidosis of the hip joints in patients undergoing long-term hemodialysis. (orig.) (orig.)

    Excess morbidity and mortality among long-term hemodialysis patients because of infectious complications is partly caused by an impairment of cellular immune defense. We hypothesized this impairment is related to an abnormal carnitine metabolism also present in these patients. In a double-blind, randomized, placebo-controlled trial, we investigated the effect of L-carnitine on phagocytic function and viability of blood leukocytes in 17 patients undergoing maintenance hemodialysis. After an observation period of 1 month, the patients received either 10 mg/kg of L-carnitine or placebo intravenously at the end of each hemodialysis session over a period of 4 months. Leukocyte oxidative metabolism was measured by means of luminol-enhanced chemiluminescence and superoxide generation after stimulation with Staphylococcus aureus or phorbol myristate acetate. Killing capacity and phagocytosis of radiolabeled staphylococci were determined. A lactate dehydrogenase (LDH) release test was applied to assess cell viability. We were unable to show an effect of L-carnitine on phagocytic function and viability in vivo. Several clinical parameters were observed during the trial. No statistically significant differences concerning dialysis-related morbidity, anemia, or reduction of blood urea nitrogen and creatinine levels were detected. Additionally, we tested the effect of L-carnitine on phagocytic function after in vitro incubation of blood leukocytes, which also showed no changes. LDH release was decreased, indicating an improved viability of these cells. The latter results were found after in vitro incubation of cells, but could not be confirmed in vivo. In summary, we could not show beneficial effects of L-carnitine administration in hemodialysis patients for the dosage and duration of treatment stated, either on phagocytic function and viability or on the clinical and biochemical parameters observed.

    Cerebral dyspraxia associated with hemodialysis is a progressive, fatal syndrome. Patients suffer from a combination of psychiatric and neurological signs and symptoms. Psychiatric manifestations include anxiety, depression, paranoid ideation, and a progressive dementia with impaired concentration, decreased memory, personality changes, and hallucinations. Neurological findings include deliberate speech, stuttering, dysarthria, dyspraxia of speech and movement, tremulousness, myoclonic activity, asterixis, and seizures. These symptoms are aggravated during and immediately following dialysis. Patients usually die within 6 months of its onset. The etiology is unknown. Treatment efforts have failed to reverse its course. Recognition of this syndrome is highlighted so that informed, critical decisions can be made as to whether to continue dialysis therapy.

    Full Text Available The primary aim of the study was to assess the medication knowledge of hemodialysis patients and to evaluate the impact of education on their medication knowledge. This was a prospective randomised study, conducted in two phases. Study population consisted of 90 hemodialysis patients, randomised into two groups. Baseline medication knowledge of these patients was assessed using medication knowledge assessment questionnaire developed for the study. During the first phase of the study, group I patients received the education provided by a trained clinical pharmacist regarding their medications for eight-weeks and group II patients were deprived of clinical pharmacist provided education but received services only by usual healthcare group. At the end of week eight, medication knowledge assessment questionnaire was applied to both the groups of patients. In the second phase, group I patients were deprived of clinical pharmacist education and group II patients were rendered with clinical pharmacist provided education for eight-weeks and medication knowledge assessment questionnaire was once again administered to both the groups at the end of week 16. At the end of week eight, there was a statistically significant ( P 0.05 improvement in the medication knowledge assessment questionnaire scores observed in group I, compared to baseline medication knowledge assessment questionnaire scores and week eight scores of group II patients. There was no significant ( P >0.05 improvement observed in scores of group II compared to baseline. At the end of week 16 of the study period, there was a statistically significant ( P 0.05 improvement in the medication knowledge assessment questionnaire scores of the group II patients compared to their baseline and week eight scores. At the end of week 16 there was a significant ( P 0.05 drop in the medication knowledge assessment questionnaire scores of group I patients compared to their week nine scores. The study confirms that medication knowledge of the hemodialysis patients was extremely poor regarding the name, indication and dosage regimen of their medications. Study emphasizes the need for the continued education to the hemodialysis patients for better understanding of the medications they use. A trained clinical pharmacist could play a vital role in educating hemodialysis patients, which has obvious benefits on therapeutic outcome.

    Background: Serum protein profiling patterns can reflect the pathological state of a patient and therefore may be useful for clinical diagnostics. Here, we present results from a pilot study of proteomic expression patterns in hemodialysis patients designed to evaluate the range of serum proteomic alterations in this population. Methods: Surface-Enhanced Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (SELDI-TOFMS) was used to analyze serum obtained from patients on periodic hemodialysis treatment and healthy controls. Serum samples from patients and controls were first fractionated into six eluants on a strong anion exchange column, followed by application to four array chemistries representing cation exchange, anion exchange, metal affinity and hydrophobic surfaces. A total of 144 SELDI-TOF-MS spectra were obtained from each serum sample. Results: The overall profiles of the patient and control samples were consistent and reproducible. However, 30 well-defined protein differences were observed; 15 proteins were elevated and 15 were decreased in patients compared to controls. Serum from one patient exhibited novel protein peaks suggesting possible additional changes due to a secondary disease process. Conclusion: SELDI-TOF-MS demonstrated dramatic serum protein profile differences between patients and controls. Similarity in protein profiles among dialysis patients suggests that patient physiological responses to end-stage renal disease and/or dialysis therapy have a major effect on serum protein profiles.

    Full Text Available To determine the frequency of hemodialysis (HD catheter related infection, causative microorganisms and predisposing factors contributing to these infections at our center, we con-ducted a prospective study in 2007 involving 57 (45.6% males patients in whom a temporary catheter was inserted for HD. The patients were followed for one month to document any episodes of hemodialysis catheter related infection (HCRI. There were 11 (19.3% patients who developed HCRI proven by blood culture; 5 patients were infected with more than one organism. Staphyloco-ccus Coagulase negative and Staphylococcus aureus (S. aureus remain the most common patho-gens. All the organisms were sensitive to antibiotics administered empirically, however, 3 patients developed multiple resistant S. aureus (MRSA. All the infected patients experienced previous epi-sodes of HCRI, which formed a risk factor in addition to low albumin when compared to the non-infected group (P=0.024 and P= 0.001, respectively. We conclude that the rate of HCRI and the causative organisms found in our study is comparable to previous reports. We still need to adopt measures to minimize the use of temporary vascular accesses by creation of fistulas in a timely fashion.

    Full Text Available Successful pregnancy outcome is an uncommon occurrence in women requiring chronic dialysis treatment. We reviewed the course and outcome of 9 pregnancies occurred in women on chronic hemodialysis in our center from 1999-2007; 5 of them ended with delivery of alive newborns, 2 with fetal deaths in-utero, and 2 with abortions. The average age of patients was 34 years. The etiology of the original kidney disease was unknown in 44.4% of the cases, and only 22.2% of the patients maintained diuresis. Dialysis started in 8 cases before the diagnosis of pregnancy. The average gestational age at diagnosis was 14 weeks. We modified the prescription of dialysis in 4 patients by increasing the frequency of the dialysis sessions to 6 per week and in 3 by increasing the duration of each session to 6 hours. Anemia was present in all the cases; 3 patients received erythropoietin and 4 patients required transfusion. The pregnancy was com-plicated in 44% of the cases by a polyhydramnios. The average time at delivery was 33 weeks and it was achieved in 80% of pregnancies through vaginal route. The average weight of newborns was to 2380 g. We conclude that pregnancy in women on hemodialysis is possible. The success of pregnancy may be influenced by the residual diuresis and early diagnosis to improve the quality of dialysis by increasing the dialysis dose.

The importance of the association of hemochromatosis with treatment for anemia among patients with CRI has not been well described. We analyzed the frequency of the C282Y and H63D mutations in the HFE gene in 201 Brazilian individuals with CRI undergoing hemodialysis. The analysis of the effects of HFE mutations on iron metabolism and anemia with biochemical parameters was possible in 118 patients of this study (hemoglobin, hematocrit, ferritin levels, transferrin saturation, and serum iron. A C282Y heterozygous mutation was found in 7/201 (3.4% and H63D homozygous and heterozygous mutation were found in 2/201 (1.0% and 46/201 (22.9%, respectively. The allelic frequencies of the HFE mutations (0.017 for C282Y mutation and 0.124 for H63D mutation did not differ between patients with CRI and healthy controls. Regarding the biochemical parameters, no differences were observed between HFE heterozygous and mutation-negative patients, although ferritin levels were not higher among patients with the H63D mutation (P = 0.08. From what we observed in our study, C282Y/H63D HFE gene mutations are not related to degrees of anemia or iron stores in CRI patients receiving intravenous iron supplementation (P > 0.10. Nevertheless, the present data suggest that the H63D mutation may have an important function as a modulating factor of iron overload in these patients.

Vitamin E tocotrienols possess anti-inflammatory and antioxidant properties. However, the impact of dietary intervention with Vitamin E tocotrienols is unknown in this population. Patients and methods: A randomized, double-blind, placebo-controlled, parallel trial was conducted in 81 patients undergoing chronic hemodialysis. Subjects were provided daily with capsules containing either vitamin E tocotrienol-rich fraction (TRF (180 mg tocotrienols, 40 mg tocopherols or placebo (0.48 mg tocotrienols, 0.88 mg tocopherols. Endpoints included measurements of inflammatory markers (C-reactive protein and interleukin 6, oxidative status (total antioxidant power and malondialdehyde, lipid profiles (plasma total cholesterol, triacylglycerols, and high-density lipoprotein cholesterol, as well as cholesteryl-ester transfer protein activity and apolipoprotein A1. Results: TRF supplementation did not impact any nutritional, inflammatory, or oxidative status biomarkers over time when compared with the baseline within the group (one-way repeated measures analysis of variance or when compared with the placebo group at a particular time point (independent t-test. However, the TRF supplemented group showed improvement in lipid profiles after 12 and 16 weeks of intervention when compared with placebo at the respective time points. Normalized plasma triacylglycerols (cf baseline in the TRF group were reduced by 33 mg/dL (P=0.032 and 36 mg/dL (P=0.072 after 12 and 16 weeks of intervention but no significant improvement was seen in the placebo group. Similarly, normalized plasma high-density lipoprotein cholesterol was higher (P<0.05 in the TRF group as compared with placebo at both week 12 and week 16. The changes in the TRF group at week 12 and week 16 were associated with higher plasma apolipoprotein A1 concentration (P<0.02 and lower cholesteryl-ester transfer protein activity (P<0.001. Conclusion: TRF supplementation improved lipid profiles in this study of maintenance hemodialysis patients. A multi-centered trial is warranted to confirm these observations.

  15. Evaluation of obesity in hemodialysis patients-relationship between visceral fat obesity and lipometabolism

    International Nuclear Information System (INIS)

    Due to various metabolic disorders, especially dyslipidemia, in patients undergoing dialysis, the prevailing reference values of indices for determining obesity may differ from those used in the general population. To clarify visceral fat levels indicating obesity in dialysis patients, we analyzed indices for determining obesity and lipid profiles, and compared the data between dialysis patients and control subjects with normal renal function. This study was conduced in 75 hemodialysis patients (HD group) aged 61.0 y on average and 58 control subjects (control group) aged 44.5 y on average. We calculated body mass index (BMI), waist circumference at the umbilical level (W), waist-height ratio (W/Ht) and evaluated visceral and subcutaneous fat areas using computed tomography (CT) at the level of the umbilicus. In addition, we measured postprandial total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C) in the serum and calculated the ratios, (TC-HDL-C)/HDL-C and TG/TC. Visceral fat area, (TC-HDL-C)/HDL-C and TG/TC in HD group were 58.1 cm2, 2.31 and 0.74, which were significantly higher than those in the control group (37.4 cm2, 1.95 and 0.52), respectively. A significant positive correlation was found between visceral fat area and BMI, W, and W/Ht in both groups. In control subjects, visceral fat area was highly correlated with (TC-HDL-C)/HDL-C (r=0.532, p less than 0.0001), and with TG/TC (r=0.286, p=0.0296). In c, and with TG/TC (r=0.286, p=0.0296). In contrast, visceral fat area in hemodialysis patients was highly correlated with (TC-HDL-C)/HDL-C (r=0.397, p=0.0004), and with TG/TC (r=0.568, p less than 0.0001). Our study demonstrated that visceral fat accumulation in hemodialysis patients increased irrespective of BMI, and the standard criteria for obesity using BMI would be unsuitable. Furthermore, we identified a novel indicator, non-fasting TG/TC, which seems to indicate visceral fat obesity in hemodialysis patients. (author)

  16. Measurment of Arteriovenous Fistula Recirculation in Hemodialysis Patients

    Full Text Available Hemodialysis access recirculation occurs when dialyzed blood returning through the venous needle reenters the extracorporeal circuit through the arterial needle rather than returning to the systemic circulation. It is important to meausre hemodialysis access recirculation for two reasons: The reentry of dialyzed blood into the extracorporeal circuite reduces solute concentration gradients across the dialysis membrane by mixing already dialyzed with undialyzed blood. As a result, the efficiency of dialysis is reduced. High degrees of recirculation can lead to a significant discrepancy between the amount of hemodialysis prescribed (prescribed Kt/V urea and the amount of hemodialysis delivdred (delivered Kt/V urea.High degrees of access recirculation indicate the presence of access stenoses, the most common cause of access thrombosis. Prospective identification and treamtnet of access stenoses improves long-term access patency rate.

  17. Small bowel enteroclysis using a hemodialysis blood pump

    International Nuclear Information System (INIS)

    The purpose of this study is to describe the usefulness of small bowel enteroclysis using a hemodialysis blood pump. Over 1 16 month period, 135 double contrast small bowel enteroclysis examinations were performed in 132 patients using a hemodialysis blood pump. Following incubation of the proximal jejunum, barium at a dilution of 50 % and 0.5 %-methylcellulose were infused at a constant rate using a hemodialysis blood pump and multiple spot films of the small intestine were obtained. Success rate, quality of radiographs, positive findings, fluoroscopic time and complications were evaluated. It spite of the long fluoroscopic time and invasiveness, double contrast small bowel enteroclysis is useful for the evaluation of small bowel disease. The infusion of barium and methylcellulose using a hemodialysis blood pump give radiographs of good quality. (author). 18 refs., 2 tabs., 10 figs

    The mental state of 20 consecutive hemodialysis patients investigated at a Nigerian renal unit was assessed using the 30-item General Health Questionnaire, Present State Examination, and clinical evaluation using the Diagnostic and Statistical Manual, revised third edition (DSM-III-R). Findings were compared with those of orthopedic patients and apparently healthy controls. A standard interview was used in eliciting sociodemographic data from the subjects. A significantly higher prevalence of psychiatric disorders was identified in hemodialysis patients (55%) than in orthopedic patients (20%) and apparently healthy controls (0%). The psychiatric disorders encountered in this hemodialysis population included major depressive episode (35%) and generalized anxiety disorder (20%). The probable reasons for the higher prevalence of psychiatric morbidity in this hemodialysis population, compared with those in Western societies, are discussed. Psychiatric morbidity was higher in patients with low levels of education, and did not show statistically significant relationship with other sociodemographic variables. PMID:9194017

    There are many variations in the delivery of hemodialysis. These variations include components of conventional dialysis, such as membrane type, dialysis dose, and session duration. In addition, alternative approaches to dialysis, such as hemodiafiltration, nocturnal hemodialysis, and short daily hemodialysis, also may be considered. For some of these practice variations, data exist to support one approach over another (eg, fistulas rather than grafts and catheters), but for many, no such data exist. Very few practice variations have been examined in randomized trials, and we are reliant predominantly on observational data. This review examines some practice variations in hemodialysis delivery, attempting to highlight which of these may be appropriate to consider when optimizing dialysis delivery in the clinic.

  4. Clearance of Tc-99m DTPA in hemodialysis and peritoneal dialysis: concise communication

    International Nuclear Information System (INIS)

    The clearance of Tc-99m DTPA was studied in 14 patients undergoing hemodialysis (HD) or peritoneal dialysis (PD). Mean Tc-99m DTPA clearance during HD was 37.8% +/- 10.1 of creatinine clearance. Mean Tc-99m DTPA clearance in PD was 65.1% +/- 10.3 of creatinine clearance. Tc-99m DTPA, with a larger molecular weight than that of creatinine, is cleared relatively better during PD than during HD. Thus Tc-99m DTPA may be used in the assessment of the effectiveness of different dialytic treatments for substances of similar molecular weight. In addition, our study shows that clearance of DTPA both in HD and PD is sufficiently high to allow the removal of this chelating agent in patients with renal failure

A população foi composta de 61,29% de adultos e 38,71% de idosos. O índice de massa corporal apontou que 12,9% dos pacientesapresentavam baixo peso e 32,26% excesso de peso. A ingestão média de nutrientes estava adequada em carboidratos, proteínas, ferro, fósforo e potássio; deficiente em calorias, lipídios e cálcio e excedente em água e sódio. Dessa forma, evidencia-se que o acompanhamento nutricional é uma conduta de destaque, em virtude da elevada prevalência de distúrbios nutricionais e dietéticos nessa população.Patients undergoing hemodialysis are frequently subjected to alterations in their nutritional state, strongly associated with increased morbimortality in this population. This study had as objective to appraise the nutritional state and the adequacy of the diet of patients undergoing hemodialysis. We studied 31 patients by means of records from a nephrology clinic located in Maringá, Paraná State, from November 2005 to February 2006. The population wascomposed of 61.29% adults and 38.71% elderly patients. The body mass index indicated that 12.9% of patients had low weight and 32.26% were overweight. The average intake of nutrients was adequate for carbohydrates, protein, iron, phosphorus and potassium, butdeficient in calories, lipids and calcium, and excessive in water and sodium. As such, it is evidenced that nutritional evaluation is an essential activity, given the high prevalence of nutritional and dietary disorders observed in this population.

    This case report concerns a hemodialysis patient with arrhythmia. A 71-year-old man had undergone hemodiafiltration (HDF) for 17 years for the treatment of chronic glomerulonephritis. Because of repeated heart failure and chronic atrial fibrillation, he could not continue receiving standard hemodialysis, which is hemodialysis using bicarbonate dialysate including a small amount of acetate. Neither elevating the sodium concentration of the dialysate nor changing the HDF modality was effective. Acetate-free biofiltration (AFB) was initiated and this treatment dramatically ameliorated the patient's intradialytic acute hypotension and arrhythmia. The patient's quality of life subsequently improved and his scores on the Short-form 36 questionnaire (a measure of quality of life) increased. AFB is an HDF technique based on the continuous postdilution infusion of a sterile isotonic bicarbonate solution. Previous studies have reported that acetate induces chemical cytokines and vasodilator substances. AFB may be effective for preventing acute hypotension and arrhythmia during dialysis and may improve quality of life, including mental status. PMID:17381538

    A soybean-derived phytochemical called genistein was used as a modifying agent to polyether sulfone/polyvinyl pyrrolidone (PES/PVP) blends to produce multi-functional hemodialysis membranes. With the aid of phase diagrams of PES/PVP/genistein blends, asymmetric porous membranes were fabricated by coagulating in non-solvent. Both unmodified and genistein modified PES/PVP membranes were shown to be non-cytotoxic to the blood cells. Unmodified PES/PVP membranes were found to reduce reactive oxygen species (ROS) levels, whereas the genistein modified membranes exhibited suppression for ˜60% of the ROS levels. Also, the genistein modified membranes revealed significant suppression of pro-inflammatory cytokines: IL-1?, IL-6, and TNF-?. Moreover, addition of PVP to PES showed the reduced trend of platelet adhesion and then leveled off. However, the modified membranes exhibited suppression of platelet adhesion at low genistein loading, but beyond 15 wt%, the platelet adhesion level rised up.

    We used the bovine carotid artery (BCA) as arteriovenous shunt for hemodialysis in 11 patients since December 1975. We discuss our results. For implantations we used two methods: straight and loop grafts. The BCA have many advantages as: good access for punction, anticoagulation not permanently necessary, volume of shunt more than 250 ml/min; the disadvantages are: increased tendence to infection and thrombosis. Thrombosis in BCA can be easier removed than in other grafts. Reduction of the complications incidence is possible with an accurate technique. We think that the BCA is very useful when Cimino-Brescia fistula has failed or is unavailable; we prefer BCA to a saphenous arteriovenous graft in these situations. PMID:624647

    Patients with end-stage renal disease on hemodialysis undergoing surgery for lung cancer represent a high-risk group because of electrolyte imbalance, anemia, hemodynamic instability, bleeding tendency, and immunocompromised state. We describe a patient on hemodialysis with three lung adenocarcinoma of the right lower lobe as an incidental finding during the clinical course of a myocardial infarction treated with drug-eluting stent implantation and double-agent antiplatelet therapy. Considering patient comorbidities, we decided to perform a right lower lobectomy and complete lymph node dissection by a minimally invasive technique. In our experience, the thoracoscopic approach allowed us to perform lobectomy with complete lymph nodes dissection without morbidity. The use of ultrasound scalpel permits a complete lymph node dissection minimizing bleeding even in a double antiplatelet therapy patient. PMID:23884666

    Full Text Available The objective of the study was to determine the level of ?2-microglobulin (?2-m in hemodialysis (HD patients and the factors affecting it. This cross sectional, hospital based study was conducted between September and December 2008 at the Hemodialysis unit of Shalamar Hospital, Lahore. All patients with end-stage renal disease (ESRD who were on main-tenance HD for more than three months were included in the study. Patients with acute renal failure and on dialysis for less than three months were excluded. Demographic data were collec-ted and details of dialysis (type of dialyzers, dialysate bath, membrane used were recorded. Blood samples of the patients were drawn for hematological (hemoglobin, hematocrit, bioche-mical (urea, creatinine, uric acid, albumin and ?2-m level measurement. The total number of patients studied was 50. The major causes of ESRD included diabetes mellitus and hypertension seen in 37 (74% and 10 patients (20%, respectively. The ?2-m levels were significantly elevated in the study patients; 92.6 ± 17.1 mg/L with a range of 54 to 130 mg/L as compared to 2.0 ± 1.29 mg/L in the control group. The patients? age had a statistically significant relationship with the ?2-m level. The major reason for increased ?2-m level was use of low-flux dialyzers. Synthetic polysulphone membrane, bicarbonate, ultra pure dialysate and duration on HD were not asso-ciated with high ?2-m levels. Also, we found an inverse relationship between ?2-m levels and serum albumin of the study patients. Our study suggests that the ?2-m levels are significantly high in dialysis patients. Use of low-flux dialyzer seems to be the major reason for the high ?2-m levels. Age and albumin have statistically significant relationship with ?2-m levels.

    There is increasing interest of the worldwide kidney community in home hemodialysis (HHD). This is due to emerging evidence of its superiority over conventional hemodialysis (HD), largely attributed to improved outcomes on intensive schedule HD, best deployed in patient's own homes. Despite published work in this area, universal uptake remains limited and reasons are poorly understood. All those who provide HD care were invited to participate in a survey on HHD, initiated to understand the beliefs, attitudes, and practice patterns of providers offering this therapy. The survey was developed and posted on the Nephrology Dialysis Transplantation-Educational (NDT-E) website. Two hundred and seventy-two responses were deemed suitable for complete analysis. It is apparent from the survey that there is great variability in the prevalence of HHD. Physicians have a great deal of interest in this modality, with majority viewing home as being the ideal location for the offer of intensive HD schedules (55%). A significant number (21%) feel intensive HD may be offered even outside the home setting. Those who offer this therapy do not see a financial disadvantage in it. Many units identify lack of appropriately trained personnel (35%) and funding for home adaptation (50.4%) as key barriers to widespread adoption of this therapy. Despite the interest and belief in this therapy among practitioners, HHD therapy is still not within reach of a majority of patients. Modifiable organizational, physician, and patient factors exist, which could potentially redefine the landscape of HHD provision. Well-designed systematic research of national and local barriers is needed to design interventions to help centers facilitate change. PMID:24814711

    Forty-seven patients with chronic renal failure presenting with a loss of vascular access precluding hemodialysis were subjected to 105 surgical procedures to establish and to maintain an arteriovenous fistulae. 67 bovine heterografts were implanted over a 30 month period and observed for 6 or more months. Fifteen, or 32% of the patients, died during the study period. Eleven patients died with a functional fistula. Twenty fistulae continued to function at the end of 36 months constituting a 46.3% graft survival rate. Hemodialysis was continued in 11 of 12 patients via a P.T.F.E. Goretex graft or via a matured Brescia Fistula. The remaining patient experienced graft failure at the end of the study period. Graft thrombosis was observed in 31 of 67 grafts placed (46%). Successful thrombectomy was achieved in 52%. Fourteen grafts developed frank aneurysms with overt rupture in 8. All patients with aneurysms were negro. Six of 8 patients with aneurysm presented with severe hypertension. Thirteen aneurysms were resected without loss of life or limb. The use of bovine grafts in hypertensive negro patients is believed to be contraindicated. PMID:921358

    2012-11-01

    Full Text Available The management of patients with concomitant xenobiotic toxicity and multisystem trauma can be complex. While hemodialysis is generally the modality of choice for extracorporeal elimination of salicylates, the potential for large volume shifts and hypotension may pose a risk in patients with traumatic brain injury. An alternative therapy to hemodialysis is continuous renal replacement therapy, which has slower clearance rates than hemodialysis, but has decreased adverse effects in cases of traumatic brain injury. However, there are few published reports of clearance rates of salicylates using continuous renal replacement therapy. We report a case of multisystem trauma with concomitant intentional salicylate overdose in which continuous renal replacement therapy was employed. The salicylate clearance rate that was obtained in this case was 7.5 mL/minute using continuous veno-venous hemodiafiltration, a form of continuous renal replacement therapy.

    Several studies suggest that there is a correlation between dose of dialysis and machine maintenance. However, in spite of the current practice, there are conflicting reports regarding the relationship between dose of dialysis or patient outcome, and machine maintenance. In order to evaluate the impact of hemodialysis machine maintenance on dialysis adequacy Kt/V and session performance, data were processed on 134 patients on 3-times-per-week dialysis regimens by dividing the patients into four groups and also dividing the hemodialysis machines into four groups according to their year of installation. The equilibrated dialysis dose eq Kt/V, urea reduction ratio (URR) and the overall equipment effectiveness (OEE) were calculated in each group to show the effect hemodialysis machine efficiency on the overall session performance. The average working time per machine per month was 270 hours. The cumulative number of hours according to the year of installation was: 26,122 hours for machines installed in 1998; 21,596 hours for machines installed in 1999, 8362 hours for those installed in 2003 and 2486 hours for those installed in 2005. The mean time between failures (MTBF) was 1.8, 2.1, 4.2 and 6 months between failures for machines installed in 1999, 1998, 2003 and 2005, respectively. Statistical analysis demonstrated that the dialysis dose eq Kt/V and URR were increased as the overall equipment effectiveness (OEE) increases with regular maintenance procedures. Maintenance has become one of the most expedient approaches to guarantee high machine dependability. The efficiency of dialysis machine is relevant in assuring a proper dialysis adequacy.

  17. Total body and regional bone mineral content in hemodialysis patients

    International Nuclear Information System (INIS)

    Bone mineral content (BMC) in the total body and lumbar spine was evaluated in 126 hemodialysis patients (60 males, 66 females) by dual photon absorptiometry with the Norland DBD 2600. Measurements of: 1) total body BMC divided by lean body mass (BMCTB/LBM), 2) bone mineral density (BMD) of total body, 3) BMD of four regional sections (head, trunk, pelvis, and legs), and 4) BMD of lumbar spine, generally showed a significant decrease in the hemodialysis patients compared to the reference population. However, arm BMD did not show a significant difference between patients and control populations. The z-score of BMCTB/LBM declined significantly throughout the duration of hemodialysis, although that of the lumbar spine BMD did not. It should be noted that the degree of decrease in BMC was more prominent in the total body measurement than in the lumbar spine measurement. There was preferential osteopenia of the total body in the hemodialysis patients. Although the lumbar spine BMD showed a lower value than the control population, the lumbar spine is not the recommended region to monitor the BMD change in hemodialysis patients. (author)

  19. Effect of ANF and iPTH on hypotension during hemodialysis

    International Nuclear Information System (INIS)

    To study the effect of ANF and iPTH on hypotension during hemodialysis, the serum ANF and iPTH levels of 36 maintenance hemodialysis patients were detected by radioimmunoassay and immunoradiometricassay. Results showed that both ANF and iPTH average levels in hemodialysis patients were markedly higher than those in normal controls (P<0.01), and decreased significantly after hemodialysis (P<0.01). Before hemodialysis, both ANF and iPTH levels in hypotensive patients were significantly higher than those in normotensive patients (P<0.05). After hemodialysis in hypotensive patients, ANF levels decreased significantly (P<0.05), and iPTH levels increased significantly (P<0.05). Conclusions: The high serum level of ANF and iPTH might be related to hypotension during hemodialysis

  20. Elimination of Gd-DTPA by means of hemodialysis

    International Nuclear Information System (INIS)

    After intravenous administration of Gd-DTPA (0.1 mmol/kg) hemodialysis was performed five times within 6 days in a patient with endstage renal failure. During the fifth hemodialysis a blood sample of 5 ml was withdrawn and Gd-concentration was measured in plasma at 342.247 nm using the method of Inductively Coupled Plasma Atomic Emission Spectrometry. Gd-concentration measured in venous and arterial blood was 6x10-6 mol/liter, corresponding to 1.5 per cent of the dose administered. If these data can be confirmed in more patients with endstage renal failure, this is the proof of effective hemodialysis of Gd-DTPA in a clinical setting. (author). 14 refs.; 1 tab

    Infection with hepatitis B virus (HBV) poses a major health threat worldwide, where the magnitude and overburden of chronic carrier state approaches 150 million chronic carriers. The prevalence of HBV is greater among dialyzed patients compared to the general population owing to their increased vulnerability to blood and its products, along with hazards posed by contaminated hemodialysis tools and devices. An electronic systematic search of the published literature was carried and data on the immunological riposte to hepatitis B vaccination among hemodialysis patients was extracted from relevant studies. End stage renal disease patients on hemodialysis have a lower or an absolutely negative riposte to HBV vaccine. Several means have been tried to improve this response with some success, nevertheless none have been universally adopted. Genetic investigations are foreseen to make a break through concerning HBV vaccination. PMID:25729482

    Full Text Available In this study, the polyvinylidene fluoride (PVDF hollow fiber hemodialysis membranes were prepared by non-solvent induced phase separation (NIPS. The influences of PVDF membrane thickness and polyethylene glycol (PEG content on membrane morphologies, pore size, mechanical and permeable performance were investigated. It was found that membrane thickness and PEG content affected both the structure and performance of hollow fiber membranes. The tensile strength and rejection of bovine serum albumin (BSA increased with increasing membrane thickness, while the Ultrafiltration flux (UF flux of pure water was the opposite. The tensile strength, porosity and rejection of BSA increased with increasing PEG content within a certain range. Compared with commercial F60S membrane, the PVDF hollow fiber membrane showed higher mechanical and permeable performance. It was proven that PVDF material had better hydrophilicity and lower BSA adsorption, which was more suitable for hemodialysis. All the results indicate that PVDF hollow fiber membrane is promising as a hemodialysis membrane.

    Full Text Available "nBackground: Anemia is a common complication accompanied by high morbidity and mortality in hemodialysis patients. Considering the fact that the reduction of erythropoietin (EPO synthesis is the main cause of uremic anemia, receiving recombinant human erythropoietin (rHuEPO can improve the condition in these patients. Some of these hemodialysis patients, however, have acceptable hemoglobin levels without any need to EPO. Higher BMI, higher albumin and leptin plasma levels and longer durations of hemodialysis are possible factors contributing to the reduced need for rHuEPO in these patients. The present study is designed to asses the relationship between the plasma levels of leptin and the reduced EPO need. "nMethods: Fifty eligible hemodialysis patients with hemoglobin levels higher than 11 mg/dl were enrolled in the cross-sectional study. The information on age, sex, hemodialysis duration and the cause of renal dysfunction were extracted from the files. The baseline plasma levels of Leptin and albumin were measured. The patients BMI and the weekly need for rHuEPO were also calculated. "nResults: There was no correlation between the weekly need for rHuEPO and sex, BMI, the cause of renal dysfunction and the plasma levels of albumin and leptin; it, however, was related with age and the duration of dialysis. While age negatively influences the weekly need, the duration of dialysis has a positive effect on the need. "nConclusion: The plasma levels of leptin are not directly correlated with the required amounts of rHuEPO, indicating that leptin is not an effective factor in erythropoiesis. Conversely, older age and shorter hemodialysis durations are accompanied by reduced need for rHuEPO.

  5. Rationale for Antioxidant Supplementation in Hemodialysis Patients

    2001-01-01

    Full Text Available Oxidative stress, which results from an imbalance between reactive oxygen species (ROS production and antioxidant defense mechanisms, is now a well recognized pathogenic process in hemodialysis (HD patients that could be involved in dialysis-related pathologies such as accelerated atherosclerosis, amyloidosis and anemia. This review is aimed at evaluating the rationale for preventive intervention against oxidative damage during HD as well as the putative causal factors implicated in this imbalance. The antioxidant system is severely impaired in uremic patients and impairment increases with the degree of renal failure. HD further worsens this condition mainly by losses of hydrophilic unbound small molecular weight substances such as vitamin C, trace elements and enzyme regulatory compounds. Moreover, inflammatory state due to the hemo-incompatibility of the dialysis system plays a critical role in the production of oxidants contributing further to aggravate the pro-oxidant status of uremic patients. Prevention of ROS overproduction can be achieved by improvement of dialysis biocompatibility, a main component of adequate dialysis, and further complimented by antioxidant supplementation. This could be achieved either orally or via the extracorporeal circuit. Antioxidants such as vitamin E could be bound on dialyzer membranes. Alternatively, hemolipodialysis consisting of loading HD patients with vitamin C or E via an ancillary circuit made of vitamin E-rich liposomes may be used.

    Insertion of a hemodialysis catheter into the superior vena cava (SVC) gives rise to complex flow patterns, which arise from the simultaneous injection and extraction of blood through different holes (ports) of the catheter. Techniques of high-image-density particle image velocimetry are employed in a scaled-up water facility. This approach allows characterization of both the instantaneous and time-averaged flow structure due to generic classes of side hole geometries. The trajectory of the injection jet is related to the ratio of the initial jet velocity to the mainstream velocity through the SVC, and to the type of distortion of the jet cross-section. Furthermore, the mean and fluctuating velocity and vorticity fields are determined. Significant turbulent stresses develop rapidly in the injection jet, which can impinge upon the wall of the simulated SVC. Immediately downstream of the injection hole, a recirculation cell of low velocity exists adjacent to the catheter surface. These and other representations of the flow structure are first evaluated for a steady throughflow, then for the case of a pulsatile waveform in the SVC, which matches that of a normal adult.

  7. Trace elements in renal disease and hemodialysis

    International Nuclear Information System (INIS)

    A number of considerations suggest that trace element disturbances might occur in patients with renal disease and in hemodialysis (HD) patients. Using particle induced X-ray emission, we demonstrated the relations between serum concentration, urinary excretion of the trace elements and creatinine clearance (Ccr) in randomized 50 patients. To estimate the effects of HD, we also observed the changes of these elements in serum and dialysis fluids during HD. Urinary silicon excretion decreased, and serum silicon concentration increased as Ccr decreased, with significant correlation (r=0.702, p<0.001 and r=0.676, p<0.0001, respectively). We also observed the increase of serum silicon, and the decrease of silicon in dialysis fluids during HD. These results suggested that reduced renal function and also dialysis contributed to silicon accumulation. Although serum selenium decreased significantly according to Ccr decrease (r=0.452, p<0.01), we could detect no change in urinary selenium excretion and no transfer during HD. Serum bromine and urinary excretion of bromine did not correlate to Ccr. However we observed a bromine transfer from the serum to the dialysis fluid that contributed to the serum bromine decrease in HD patients

    Home hemodialysis (HHD) started in Japan in 1969. It has been done in the largest number of patients with the purpose of better social reintegration, followed by patients for whom commuting to a hospital is geographically difficult. In a subanalysis of the JSDT patient registry, the survival rate at 9 years for male patients excluding those with diabetes was significantly better in HHD patients than in facility dialysis patients. This result was thought to indicate that HHD was superior treatment both medically and socially, but it has not increased greatly because of conditions that impede the implementation of HHD, such as finding a caregiver and the burden on the caregiver, as well as the burden of light, heat, and water costs. However, long-duration dialysis and frequent dialysis are done even in general dialysis treatment, and the number of HHD patients has increased recently because of some improvement in health insurance payments for HHD in 1998. The spread of HHD is essential also in the broad implementation of diversifying HD modalities, and maintaining an accurate registry of HHD patients, analyzing factors that affect survival rates with each modality, clarifying conditions for adequacy of dialysis, and clarifying which treatments are superior are important future issues for dialysis treatment.

    Full Text Available This study was performed to evaluate whether any electrocardiogram (ECG para-meter can predict the presence of hyperkalemia in patients on maintenance hemodialysis (HD. In January 2006, we conducted a cross-sectional study of 80 stable patients with end-stage renal disease from four university-based HD units of Tehran, Iran, receiving conventional thrice-weekly HD. Pre-HD serum electrolyte values and conventional 12-lead ECG were obtained from each pa-tient. Bivariate linear regression was used for assessing relationship of the study variables with hyperkalemia (K + > 5.2 mg/dL. Multivariable logistic regression was used for evaluating inde-pendent relationship between decreased T wave duration (? 170 ms and other variables. Bivariate correlation analysis showed a significant inverse correlation between serum potassium concentration and T wave duration (P < 0.05. None of the patients with serum potassium of ? 5.6 mg/dL had T wave duration > 200 ms. Multivariate logistic analysis, after adjustment for other factors, also showed a significant relationship between decreased T wave duration (? 170 ms and hyper-kalemia. We conclude that although hyperkalemia does not induce the usual ECG changes in HD patients, decreased T wave duration was found to be a good indicator of this lethal condition.

    Full Text Available The use of dialysis in patients with end-stage renal disease (ESRD remains one of the most resource-intensive and hence, expensive therapeutic interventions. The purpose of this study was to assess the cost of hemodialysis (HD in Iran. This study was conducted in the Department of Nephrology at the Imam Khomeini Hospital of Tehran University of Medical Sciences, Iran, between April 2006 and June 2007. Patients with ESRD on chronic HD were involved in the study. Relevant data were collected using interview and questionnaire. Analyzed costs included: transportation plus absence from work, treatment instruments, drugs and other medical procedures, diet, staff salary, equipment and building support services, non-medical supplies, depreciation of installations and equipments, depreciation of reverse osmosis (RO and building rent. Sixty-three patients of whom 47.7% were males and 52.3% were females, with mean age of 47 ± 12 years were studied. The estimated cost of each HD session was about 74 US dollars by which an annual cost of $11549 could be estimated for each patient. Transportation and work leaves (28.9%, staff costs and salaries (21.5%, and treatment instruments (21.1% were among the greatest expenses. We conclude that the annual cost of dialysis in Iran is similar to other developing countries, but significantly less than the cost in developed countries.

  11. Induction of IL-1 during hemodialysis: Transmembrane passage of intact endotoxins (LPS)

    International Nuclear Information System (INIS)

    Circulating monocytes of patients undergoing chronic hemodialysis are triggered to produce interleukin-1 (IL-1) in vivo. Intradialytic induction of IL-1 is associated with complement activation in patients dialyzed with first-use cellulose membranes. Chronic stimulation of IL-1 production occurs because of an yet unidentified mechanism in patients dialyzed with high permeability membranes. The present study demonstrates that intact bacterial lipopolysaccharide (LPS) molecules may cross cuprophan, AN69 and polysulfone membranes under in vitro conditions simulating in vivo hemodialysis. The experiments used purified LPS from Neisseria meningitidis and LPS from Pseudomonas testosteroni, a bacterial strain grown out from a clinically used dialysate. LPS were purified to homogeneity and radiolabeled. Transmembrane passage of 3H-labeled LPS was observed within the first five minutes of dialysis. A total of 0.1 to 1% of 3H-labeled LPS were recovered in the dialysate compartment after one hour of dialysis. High amounts of LPS, representing 40 to 70% of the amount originally present in the dialysate, were absorbed onto high permeability membranes. Low amounts of LPS were absorbed onto cuprophan membranes. The amount of LPS absorbed decreased with the concentration of LPS in the dialysate. LPS recovered from the blood compartment exhibited the same molecular weight as that used to contaminate the dialysate. Biochemically detectable transmembrane passage of LPS was not associatesmembrane passage of LPS was not associated with that of material detectable using the limulus amebocyte lysate (LAL) assay. An IL-1-inducing activity was, however, detected in the blood compartment upon dialysis with high permeability membranes, as previously found by others with cuprophan membranes

    Lanthanum carbonate (LC) has been administered in a chewable tablet form for patients with hyperphosphatemia undergoing dialysis. However, some patients have difficulty chewing the tablets. LC oral powder has recently been released in Japan. The purpose of this study was to clarify the efficacy of LC oral powder form compared with that of chewable tablet form. The efficacy and safety of LC oral powder was retrospectively assessed in hemodialysis patients who switched from chewable tablet form to oral powder form without dose modification. Thirty-six patients (mean age, 66.8 ± 10.5 years; male, 64%; 39% with diabetes; mean duration of dialysis treatment, 99.2 ± 95.6 months) were enrolled in this study between June and July of 2012. Changes in clinical data and adverse events after the switch to oral powder form were investigated. The average dose of LC was 1180 ± 520 mg/day. Serum phosphorus levels were significantly decreased after the switch from chewable tablet form to oral powder form (5.3 ± 1.7 mg/dL at baseline vs. 4.9 ± 1.2 mg/dL at after 1 month after, P = 0.038). In contrast, no significant differences were observed in serum calcium and parathyroid hormone levels. Furthermore, no significant differences were evident in weight gain after the switch to oral powder form (2.5 ± 1.2 kg at baseline vs. 2.4 ± 1.1 kg at 1 month after the switch, P = 0.29). No serious adverse events were recorded. Our results suggest that LC is more effective in oral powder form than chewable tablet form for hemodialysis patients. PMID:24134326

    Full Text Available Objective: The aim of this study was to evaluate the effects of hemodialysis (HD on right ventricular echocardiographic parameters in patients with end-stage renal failure (ESRF. Methods: Forty-three uremic patients who underwent echocardiography before and 30 minutes after dialysis included in this prospective observational study. Right ventricular systolic function was evaluated using tricuspid annular plane systolic excursion (TAPSE by M-mode echocardiography and tricuspid lateral annular systolic velocity (Sa by tissue Doppler echocardiography whereas diastolic function was evaluated using tricuspid early (E and late (A diastolic flow velocities by conventional and tricuspid lateral annular early (Ea and late (Aa diastolic velocities by tissue Doppler echocardiography. Myocardial performance index was taken as an indicator of global functions. Paired t test or Wilcoxon test were used for statistical analysis where appropriate.Results: E decreased significantly (68±13 cm/s and 56±12 cm/s before and after HD, respectively; p<0.0001 but A did not (p=0.797.TAPSE was 1.84±0.34 cm before HD and showed a significant increase to 2.03±0.20 cm after HD (p=0.006. Right ventricular MPI, Sa and Aa did not change significantly by dialysis (p=0.504; p=0.118 and p=0.150 respectively whereas Ea decreased to 8.8±2.5 cm/s from 11.3±3.4 cm/s (p<0.001. Ea/Aa ratio also decreased significantly to 0.69±0.35 from 0.84±0.44 with HD (p=0.007.Conclusion: The results of this study indicates that parameters of right ventricular systolic function such as Sa and MPI are independent of preload whereas the conventional and tissue Doppler parameters of right ventricular diastolic function are preload dependent in patients with end-stage renal failure who undergo regular hemodialysis.

  15. 131I therapy for toxic adenoma in patient on hemodialysis

    International Nuclear Information System (INIS)

    Treatment with radioactive iodine (131I) may be necessary for toxic adenoma of the thyroid in patients with end-stage renal disease (ESRD) who require hemodialysis (HD). Because 131I is cleared mainly by the kidneys in patients with normal renal function, many issues arise as in patients who require 131I treatment but who are on hemodialysis, as radiation safety considerations, contamination of equipment, lines and filter and disposal of wastes. This paper presents a case report of a patient on dialysis that required treatment with 131I. (author)

    To describe how to make a swine hemodialysis fistula model and report our initial experience to test the feasibility of endovascular radiation therapy with Holmium-166 filled balloon catheters. The surgical formation of arterio-venous fistula (AVF) was performed by end-to-side anastomosis of the bilateral jugular vein and carotid artery of 6 pigs. After 4 weeks, angiograms were taken and endovascular radiation was delivered to the venous side of AVF with Holmium-166 filled balloon catheters. Pigs were sacrificed 4 weeks after the radiation and AVFs were harvested for histological examination. All animals survived without any morbidity during the experimental periods. The formation of fistula on the sides of necks was successful in 11 of the 12 pigs (92%). One AVF failed from the small jugular vein. On angiograms, 4 of the 11 AVFs showed total occlusion or significant stenosis and therefore, endovascular radiation could not be performed. Of 7 eligible AVFs, five underwent successful endovascular radiation and two AVFs did not undergo radiation for the control. Upon histologic analysis, one non-radiated AVF showed total occlusion and others showed intimal thickening from the neointimal hyperplasia. Formation of the swine carotid artery-jugular vein hemodialysis fistula model was successful. Endovascular radiation using a Holmium-166 filled balloon catheter was safe and feasible.

    Full Text Available Abstract Background Patients on peritoneal and hemodialysis have accelerated atherosclerosis associated with an increase in cardiovascular morbidity and mortality. The atherosclerosis is associated with increased arterial stiffness, endothelial dysfunction and elevated oxidative stress and inflammation. The aims of this study are to investigate the effects of peritoneal and hemodialysis on arterial stiffness, vascular function, myocardial structure and function, oxidative stress and inflammation in incident patients with end stage kidney disease. Methods This is an observational study. Eighty stage five CKD patients will be enrolled and followed for one-year. Primary outcome measures will be changes in 1 arterial stiffness measured by aortic pulse wave velocity, 2 oxidative stress assessed by plasma F2 isoprostanes and 3 inflammation measured by plasma pentraxin-3. Secondary outcomes will include additional measures of oxidative stress and inflammation, changes in vascular function assessed using the brachial artery reactivity technique, carotid artery intimal medial thickness, augmentation index and trans thoracic echocardiography to assess left ventricular geometry, and systolic and diastolic function. Patients will undergo these measures at baseline (6–8 weeks prior to starting dialysis therapy, then at six and 12 months after starting dialysis. Discussion The results of this study may guide the choice of dialysis modality in the first year of treatment. It may also lead to a larger study prospectively assessing the effect of dialysis modality on cardiovascular morbidity and mortality. Trial Registration ACTRN12609000049279

  1. Perceived illness intrusion among patients on hemodialysis

    International Nuclear Information System (INIS)

    Dialysis therapy is extremely stressful as it interferes with all spheres of daily activities of the patients. This study is aimed at understanding the perceived illness intrusion among patients on hemodialysis (HD) and to find the association between illness intrusion and patient demo-graphics as well as duration of dialysis. A cross sectional study involving 90 patients with chronic kidney disease (CKD) stage V, on HD was performed during the period from 2005 to 2006. The subjects included were above 18 years of age, willing, stable and on dialysis for at least two months. Patients with psychiatric co-morbidity were excluded. A semi-structured interview schedule covering sociodemographics and a 13 item illness intrusion checklist covering the various aspects of life was carried out. The study patients were asked to rate the illness intrusion and the extent. The data were analyzed statistically. The mean age of the subjects was 50.28 + - 13.69 years, males were predominant (85%), 73% were married, 50% belonged to Hindu religion, 25% had pre-degree education, 25% were employed and 22% were housewives. About 40% and 38% of the study patients belonged to middle and upper socio-economic strata respectively; 86% had urban background and lived in nuclear families. The mean duration on dialysis was 24 + - 29.6 months. All the subjects reported illness intrusion to a lesser or greater extent in various areas including: health (44%), work (70%) finance (55%), diet (50%) sexuawork (70%) finance (55%), diet (50%) sexual life (38%) and psychological status (25%). Illness had not intruded in areas of relationship with spouse (67%), friends (76%), family (79%), social (40%) and religious functions (72%). Statistically significant association was noted between illness intrusion and occupation (P= 0.02). (author)

    Full Text Available Restless legs syndrome (RLS is common among dialysis patients, with a reported prevalence of 6-60%. The prevalence of RLS in Syrian patients on hemodialysis (HD is not known. The purpose of this study is to determine the prevalence of RLS in patients on regular HD, and to find the possible correlation between the presence of RLS and demographic, clinical, and biochemical factors. One hundred and twenty-three patients (male/female = 70/53, mean age = 41.95 ± 15.11 years on HD therapy at the Aleppo University Hospital were enrolled into the study. RLS was diagnosed based on criteria established by the International Restless Legs Syn-drome Study Group (IRLSSG. Data procured were compared between patients with and without RLS. Applying the IRLSSG criteria for the diagnosis, RLS was seen in 20.3% of the study pa-tients. No significant difference in age, gender, and intake of nicotine and caffeine was found between patients with and without the RLS. Similarly, there was no difference between the two groups in the duration of end-stage renal disease (ESRD, the period of dialysis dependence, dialysis adequacy, urea and creatinine levels, and the presence of anemia. The co-morbidities and the use of drugs also did not differ in the two groups. Our study suggests that the high prevalence of RLS among patients on HD requires careful attention and correct diagnosis can lead to better therapy and better quality of life. The pathogenesis of RLS is not clear and further studies are required to identify any possible cause as well as to discover the impact of this syndrome on sleep, quality of life, and possibly other complications such as cardiovasculare disease.

There are three main types of access: native arteriovenous fistula (AVF, arteriovenous graft, and central venous catheter (CVC. AVF, described by Brescia and Cimino, remains the first choice for chronic HD. It is the best access for longevity and has the lowest association with morbidity and mortality, and for this reason AVF use is strongly recommended by guidelines from different countries. Once autogenous options have been exhausted, prosthetic fistulae become the second option of maintenance HD access alternatives. CVCs have become an important adjunct in maintaining patients on HD. The preferable locations for insertion are the internal jugular and femoral veins. The subclavian vein is considered the third choice because of the high risk of thrombosis. Complications associated with CVC insertion range from 5% to 19%. Since an increasing number of patients have implanted pacemakers and defibrillators, usually inserted via the subclavian vein and superior vena cava into the right heart, a careful assessment of risk and benefits should be taken. Infection is responsible for the removal of about 30%–60% of HD CVCs, and hospitalization rates are higher among patients with CVCs than among AVF ones. Proper VA maintenance requires integration of different professionals to create a VA team. This team should include a nephrologist, radiologist, vascular surgeon, infectious disease consultant, and members of the dialysis staff. They should provide their experience in order to give the best options to uremic patients and the best care for their VA.Keywords: arteriovenous fistula, prosthetic grafts, central venous catheter, infection

    Full Text Available Abstract Background Staphylococcus aureus, particularly methicillin resistant (MRSA, is a common pathogen among patients receiving hemodialysis. To evaluate nasal carriage, molecular characterization and effectiveness of decolonization of MRSA among patients receiving hemodialysis in Taiwan, we conducted this study. Methods From January to June 2011, two nasal samplings with a 3-month interval were obtained from patients undergoing hemodialysis in a medical center (CGMH, and in a local hospital (YMH and sent for detection of MRSA. For MRSA carriers, decolonization procedures were administered. All patients in CGMH were observed if MRSA infections occurred during the study period. Results A total of 529 nasal specimens (265 from CGMH and 264 from YMH were collected from 296 patients (161 from CGMH and 135 from YMH. 233 patients participated in both surveys. Average one-time point MRSA carriage rate was 3.8%, and the rate was up to 6.9% for those with two-time point surveys. No additional significant factor for MRSA carriage was identified. Seventy percent of the 20 colonizing MRSA isolates, though categorized as healthcare-associated strains epidemiologically, shared common molecular characteristics of the local community-associated strains. Only one of the 20 MRSA-colonized patients failed decolonization and had persistent colonization, while without any intervention, 17 (61% of 28 patients with methicillin-sensitive S. aureus colonization in the first survey had persistent colonization of a genetically indistinguishable strain. Within the study period, two patients (1.24% in CGMH, one with MRSA colonization (9.1%, developed MRSA infection. Conclusion A substantial proportion of patients receiving hemodialysis in Taiwan had MRSA colonization, mostly genetically community strains. Decolonization procedures may effectively eliminate MRSA colonization and might reduce subsequent MRSA infection in these patients.

Anti-HCV antibodies were determined using a fourth generation ELISA (Innotest HCV Ab IV kit and positive blood samples were tested using a recombinant assay kit (Inno-LIA HCV Ab III, both kits from Innogenetics N.V., Belgium. The findings indicate a lack of HCV seroconversion in the hemodialysis patients over the study period, confirmed by the recombinant assay. Risk factors for HCV infection were 0.3270 (95% confidence interval: 0.01323-8.080 in patients undergoing hemodialysis. The findings suggest a lack of significant sources for HCV infection due to the preventive measures to avoid its transmission in the hemodialysis unit.Durante período de 2 anos, estudamos a incidência da infecção pelo vírus da hepatite C (VHC em 29 pacientes em tratamento de diálise, com idades entre 15 e 75 anos (c ± DS; 45 ± 39,5 anos, procedentes da unidade de hemodiálise do Hospital Universitário de Maracaibo, Estado Zulia, Venezuela. Para a detecção dos anticorpos contra o VHC (anti-VHC utilizamos a técnica de imunoensaio enzimático (ELISA, Innotest HCV Ab IV e em amostras reativas por ELISA, utilizamos o método de immunoblot recombinante de terceira geração (Inno-LIA HCV Ab III, ambos da casa comercial Innogenetics N.V., Bélgica. Os resultados demonstram ausência de soroconversão ao VHC nos pacientes hemodializados durante o período estudado, o que foi confirmado pelo método de imunoblot recombinante. Os fatores de risco ao VHC foram 0,327 (95% CI: 0,01323 - 8,080 nos pacientes submetidos ao tratamento de diálise.

    Introduction/objective: To describe and evaluate percutaneous treatment methods of complications occurring during recanalization of thrombosed hemodialysis access grafts. Methods and materials: A retrospective review of 579 thrombosed hemodialysis access grafts revealed 48 complications occurring during urokinase thrombolysis (512) or mechanical thrombectomy (67). These include 12 venous or venous anastomotic ruptures not controlled by balloon tamponade, eight arterial emboli, 12 graft extravasations, seven small hematomas, four intragraft pseudointimal 'dissections', two incidents of pulmonary edema, one episode of intestinal angina, one procedural death, and one distant hematoma. Results: Twelve cases of post angioplasty ruptures were treated with uncovered stents of which 10 resulted in graft salvage allowing successful hemodialysis. All arterial emboli were retrieved by Fogarty or embolectomy balloons. The 10/12 graft extravasations were successfully treated by digital compression while the procedure was completed and the graft flow was restored. Dissections were treated with prolonged Percutaneous Trasluminal Angioplasty (PTA) balloon inflation. Overall technical success was 39/48 (81%). Kaplan-Meier Primary and secondary patency rates were 72 and 78% at 30, 62 and 73% at 90 and 36 and 67% at 180 days, respectively. Secondary patency rates remained over 50% at 1 year. There were no additional complications caused by these maneuvers. Discussions and conclusion: The majority of complications occurring during percutaneous thrombolysis/thrombectomy of thrombosed access grafts, can be treated at the same sitting allowing completion of the recanalization procedure and usage of the same access for hemodialysis.

    The present study was conducted to investigate depression in caregivers of elderly hemodialysis patients. Caregivers answered a self-administered questionnaire about various factors that may affect their depression, and also completed a Center for Epidemiologic Studies Depression Scale evaluation (CESD). The frail elderly who received regular nurse visits were used as controls. Compared with the caregivers of controls, those of hemodialysis patients spent less time on caregiving and had more time to go out unaccompanied by their patients. Males were numerous among hemodialysis patients than in the controls. Compared with the controls, hemodialysis patients were less likely to be older old (80 years old and more), diagnosed as demented or severely limited in activities of daily living (ADL). On the other hand, we did not find any significant difference between the two groups with regard to either the prevalence of depression, the rate of those who experienced any life event such as to cause depression within 6 months (e.g., death of family member), duration of caregiving or time looking after patients. Caregivers of hemodialyis patients may feel a heavy burden because they are obliged to play an important role in supporting patients on dialysis. They seem to need more social support regardless of whether or not their patients suffer from dementia. PMID:11680974

    Full Text Available Abstract Background Sexual dysfunction is common in patients with end stage renal disease (ESRD and treatment options are limited. Observational studies suggest that nocturnal hemodialysis may improve sexual function. We compared sexual activity and responses to sexual related questions in the Kidney Disease Quality of Life Short Form questionnaire among patients randomized to frequent nocturnal or thrice weekly conventional hemodialysis. Methods We performed a secondary analysis of data from an RCT which enrolled 51 patients comparing frequent nocturnal and conventional thrice weekly hemodialysis. Sexual activity and responses to sexual related questions were assessed at baseline and six months using relevant questions from the Kidney Disease Quality of Life Short Form questionnaire. Results Overall, there was no difference in sexual activity, or the extent to which people were bothered by the impact of kidney disease on their sex life between the two groups between randomization and 6?months. However, women and patients age? Conclusions Our results suggest that frequent nocturnal hemodialysis is not associated with an improvement in sexual activity in all patients but might have an effect on the burden of kidney disease on sex life in women and patients less than 60?years of age. The validity of these subgroup findings require confirmation in future RCTs.

    Some ?-blockers are efficiently removed from the circulation by hemodialysis ("high dialyzability") whereas others are not ("low dialyzability"). This characteristic may influence the effectiveness of the ?-blockers among patients receiving long-term hemodialysis. To determine whether new use of a high-dialyzability ?-blocker compared with a low-dialyzability ?-blocker associates with a higher rate of mortality in patients older than age 66 years receiving long-term hemodialysis, we conducted a propensity-matched population-based retrospective cohort study using the linked healthcare databases of Ontario, Canada. The high-dialyzability group (n=3294) included patients initiating atenolol, acebutolol, or metoprolol. The low-dialyzability group (n=3294) included patients initiating bisoprolol or propranolol. Initiation of a high- versus low-dialyzability ?-blocker was associated with a higher risk of death in the following 180 days (relative risk, 1.4; 95% confidence interval, 1.1 to 1.8; P<0.01). Supporting this finding, we repeated the primary analysis in a cohort of patients not receiving hemodialysis and found no significant association between dialyzability and the risk of death (relative risk, 1.0; 95% confidence interval, 0.9 to 1.3; P=0.71). ?-Blocker exposure was not randomly allocated in this study, so a causal relationship between dialyzability and mortality cannot be determined. However, our findings should raise awareness of this potentially important drug characteristic and prompt further study. PMID:25359874

    Full Text Available Hepatitis B has proved to be a major health hazard in hemodialysis patients. In order to investigate the hepatitis B virus (HBV infection profile in the hemodialysis population of Goiânia city - Central Brazil, all dialysis patients (N=282 were studied. The prevalence of any HBV marker (HBsAg, anti-HBs, and anti-HBc was 56.7% (95% CI: 51.1-62.7, ranging from 33.3% to 77.7% depending on dialysis unit. HBV-DNA was detected in 67.6% and 88.2% of the HBsAg-positive serum samples, in 91.3% and 100% of the HBsAg/HBeAg-positive samples, and in 18.2% and 63.6% of the HBsAg/anti-HBe-reactive sera by hybridization and PCR, respectively. The length of time on hemodialysis was significantly associated with HBV seropositivity. Only 10% of the patients reported received hepatitis B vaccination. The findings of a high HBV infection prevalence in this population and the increased risk for HBV infection on long-term hemodialysis suggest the environmental transmission, emphasizing the urgent need to evaluate strategies of control and prevention followed in these units.

  16. Lessons for Medicare Part D in the hemodialysis community

    2006-07-01

    Full Text Available Abstract Background Medicare beneficiaries without prescription drug coverage consistently fill fewer prescriptions than beneficiaries with some form of drug coverage due to cost. ESRD patients, who are disproportionately poor and typically use multiple oral medications, would likely benefit substantially from any form of prescription drug coverage. Because most hemodialysis patients are Medicare-eligible, they as well as their providers would be expected to be well informed of changes in Medicare prescription drug coverage. By examining the level of understanding and use of the temporary Medicare Prescription Drug Discount Card Program in the hemodialysis population, we can gain a better understanding of the potential long-term utilization for Medicare Part D. Methods We surveyed English-speaking adult hemodialysis patients with Medicare coverage from two urban hemodialysis centers affiliated with the University of California San Francisco (UCSF during July and August 2005 (n = 70. We also surveyed University- and community-based nephrologists and non-physician dialysis health care professionals over the same time frame (n = 70. Results Fifty-nine percent of patients received prescription drug coverage through Medi-Cal, 20% through another insurance program, and 21% had no prescription drug coverage. Forty percent of patients with no prescription drug coverage reported "sometimes" or "rarely" being able to obtain medications vs. 22% of patients with some form of drug coverage. None of the patients surveyed actually had a Medicare-approved prescription drug card, and of those who intended to apply, only 10% reported knowing how to do so. Only 11% health care professionals knew the eligibility requirements of the drug discount cards. Conclusion Despite a significant need, hemodialysis patients and providers were poorly educated about the Medicare Prescription Drug Discount Cards. This has broad implications for the dissemination of information about Medicare Part D.

    Full Text Available Tumor markers are widely used for screening certain tumors, however, their use in chronic hemodialysis (HD patients in hemodialysis has been a controversial issue. To determine the reliability of the tumor markers, CA 15-3, CA 19-9, CA 125, Alpha-Fetoprotein and Carcinoem-bryonic antigen (CEA, in chronic HD patients, and the impact of active hepatitis C on the variation of tumor markers values, we studied 30 patients (16 men and 14 women aged from 40 to 78 years old (mean age: 54 ± 5 years, on intermittent hemodialysis (with a mean duration of 10.5 years, and clinically free from neoplastic disease. The control group included 30 healthy volunteers. All subjects were of Greek origin and residents of the Korinthos region. The tumor markers were measured once in the control group and before and afterwards the hemodialysis, in the study group. Alpha fetopro-tein was within normal limits in all the study patients, CA 125 was slightly increased in one (3.3% patient, CA 15-3 levels were twice normal in 4 (13% patients, CA 19-9 levels were twice normal in 5 (16% patients, and CEA levels were twice normal in 4(13% patients. More than half (7/13 of anti HCV positive and all Australian antigen positive patients had abnormal serum levels of CA 15-3 and CA 125 after hemodialysis treatment. We conclude that measurement of some tumor markers such as alfa-fetoprotein may be beneficial in HD patients. However, the elevated levels of other markers including CA 15-3 and CA 125 are not specific for neoplasms and related to active hepatitis C.

    Full Text Available Objective: Cardiovascular disease is the leading cause of morbidity and mortality in patientsundergoing hemodialysis. Increased arterial stiffness is an independent predictor of cardiovascularmortality in end stage renal disease (ESRD. We hypothesized that the hemodialysis procedure itself,through alterations in electrolytes and blood volume, could contribute to the increased cardiovascular riskencountered in ESRD. Material and methods: 28 chronic hemodialysis patients were evaluated before andafter hemodialysis. We determined serum calcium, arterial stiffness (using pulse wave analysis andhemodynamic parameters. Results: Serum calcium increased significantly during the dialysis treatment(P<0.01. Also, significant increase in stiffness index occurred at the end of dialysis (P=0.02. Bothincrements were correlated with ultrafiltration. No significant changes in systolic blood pressure, diastolicblood pressure or heart rate were noticed during hemodialysis. Arterial stiffness significantly increasedafter hemodialysis, unrelated to hemodynamic parameters. Conclusion: This vascular response may bean explanation for greater vulnerability regarding cardiovascular events in ESRD patients.

    2008-01-01

    Full Text Available The hemodialysis procedure is thought to be a physical stressor in the majority of hemodialyzed patients. Previous studies suggest that elevated salivary amylase level may correlate with increased plasma norepinephrine level under psychological and physical stress conditions. In this study, we investigated biological stress reactivity during hemodialysis treatment using salivary amylase activity as a biomarker. Seven patients (male/female = 5/2, age:67.7+ /? 5.9 years who had been receiving regular 4 h hemodialysis were recruited. Salivary amylase activity was measured using a portable analyzer every hour during the hemodialysis session. Salivary amylase activity was shown to be relatively stable and constant throughout hemodialysis, whereas there were significant changes in systolic blood pressure and pulse rate associated with blood volume reduction. Our results show that hemodialysis treatment per se dose not affect salivary amylase activity.

As to the IgA amount present in the saliva, only three patients showed a low density. CONCLUSIONS: Patients presenting chronic kidney disease disclosed a tendency for greater bacterial plaque concentration, high formation of dental calculus suggesting the need for periodontal treatment comprising supra and sub gingival scraping.

  12. Changes of plasma ET, ANP and PRL levels in patients on chronic hemodialysis

    International Nuclear Information System (INIS)

    Objective: To explore the changes of plasma endothelin (ET), atrial natriuretic peptide (ANP) and prolactin (PRL) levels in patients on chronic hemodialysis. Methods: Plasma ET, ANP and PRL levels were determined with RIA in 38 patients on chronic hemodialysis and 30 controls. Results: Before hemodialysis, plasma ET, ANP and PRL levels in patients with chronic renal failure were significantly higher than those in the controls (P0.05). Conclusion: Determination of plasma ET, ANP and PRL levels is clinically useful for understanding the effect of hemodialysis

    Full Text Available Introduction. Serotonin receptors are present in osteoblasts and osteoclasts, and serotonin affects bone metabolism. The association of plasma serotonin with markers of bone formation and bone resorption in hemodialysis patients was evaluated. Materials and Methods. Twenty-four hemodialysis patients (11 diabetics and 22 healthy volunteers were enrolled into the study. Serotonin was assessed in platelet-free plasma, whereas the markers of osteoblastic activity N-terminal midfragment osteocalcin and total procollagen type-1 aminoterminal propeptide as well as the marker of osteoclastic activity ?-isomerized C-terminal cross-linked peptide of collagen type I were measured in serum. Serum intact parathyroid hormone was also assessed. Results. Serotonin did not significantly differ between hemodialysis patients and healthy volunteers. All evaluated markers of bone metabolism and intact parathyroid hormone were much higher in hemodialysis patients. Serotonin was significantly correlated with all evaluated markers of bone metabolism in hemodialysis patients. Serotonin was reversely related to the patients' age. Serotonin, osteocalcin, procollagen type-1 aminoterminal propeptide, and ?-isomerized C-terminal cross-linked peptide of collagen type I were much lower in diabetic hemodialysis patients. Conclusions. Serotonin may increase both bone formation and bone resorption in hemodialysis patients. The reverse relation of serotonin to patients' age as well as its lower levels in diabetic hemodialysis patients indicate that low plasma serotonin may contribute to the higher incidence of low-turnover bone disease that characterizes old and diabetic hemodialysis patients.

    DEFF Research Database (Denmark)

    Reinhard, Mark; Frystyk, Jan

    Background Hemodialysis (HD) is a catabolic procedure that may contribute to the high frequency of protein-energy wasting among patients receiving maintenance HD. The present study investigated the additional effect of glucose and glucose-insulin infusion on liver protein synthesis during HD compared with a meal alone. Methods In a randomized cross-over study with three arms, 11 non-diabetic HD patients were assigned to receive a conventional HD session with either: • no treatment (NT) • IV infusion of glucose (G) • IV infusion of glucose-insulin (GI) During infusions blood glucose levels were maintained at 8.0-10.0 mmol/L by additional glucose infusion. Glucose and glucose-insulin infusions were commenced 2 h prior to HD and continued throughout the HD session. Fasting blood samples were collected at baseline before infusion and followed by the only meal allowed during the study. Results Blood glucose and insulin: The change in blood glucose differed significantly from baseline (-120 min) to end of HD (240 min) between the NT group and the G group (p=0.002); there was no significant difference in the change between the NT group and the GI group (p=0.06), or between the G group and the GI group (p=0.15). Fibrinogen and albumin: There was an overall increase in serum albumin (38.8±2.1 to 40.4±2.5 g/L, p<0.0001) and in serum fibrinogen (11.7±1.7 to 12.8±1.8 µmol/L, p<0.0001) from HD start (0 min) to 2 h post HD (360 min), but no significant difference in the change in either albumin (p=0.12) or fibrinogen (p=0.12) between the groups. IGFBP-1: During the first 4 h after baseline (-120 min) we observed an overall decrease in serum IGF-binding protein 1 (IGFBP-1) (from 267±147 to 140±84 µg/L, p<0.0001), but no difference in the change between groups (p=0.41). However, from 4 h after baseline to the end of the study there was a significant difference in the change in serum IGFBP-1 between the groups (p=0.003) with a significant increase in serum IGFBP-1 in the NT group (p<0.0001), but not in the G group or GI group (p=0.50 and p=0.07, respectively). Conclusions Compared with a meal neither glucose nor glucose-insulin infusion appear to have any extra effects on liver protein synthesis during HD.

    Background Hemodialysis patients are exposed to blood and blood products more than the general population and are also at higher risk for hepatitis B (HB) contamination. For these reasons, it is highly recommended that this patient population gets the HB vaccine. The efficacy of the vaccine is measured by measuring titers of antibody in the serum of the patient. A minimum titer of 10 mIU/mL is considered to be a response. The conversion rate in hemodialysis patients ranges from 50% to 80%, as compared to the general population where the conversion rate is over 95%. As opposed to the general population, end-stage renal patients on hemodialysis do not always respond to the vaccine. The main objective in this study was to try to identify factors that may hinder the response. Correction of these factors in the future may help non-responders. Methods This was a retrospective chart review at a single hemodialysis center to compare the laboratory and clinical differences between responders and non-responders. Inclusion criteria are hemodialysis patients who received the HB vaccine and patients with concomitant hepatitis C. Exclusion criteria are patients who refused the vaccine and patients who did not complete the vaccine course. Results There are a total of 108 subjects included in the study, out of which 44 (42.3%) are responders to the HB vaccine. A multivariate logistic regression was performed using the statistically significant risk factors as identified by the univariate logistic regression, including age range, albumin, hemodialysis vintage, vascular access and diabetes status. The results from the multivariate logistic regression show that advanced age (P = 0.005) and diabetes status (P = 0.003) are found to be strong independent risk factors of responder status. The type of vascular access (AVF or other types) is also marginally statistically significant (P = 0.05). Conclusions In this retrospective chart review comparing HB vaccine in responders versus non-responders, we found that advanced age and a history of diabetes are independent risk factors in predicting responder status.

  18. Three-dimensional imaging of skeletal complications in hemodialysis patients

    International Nuclear Information System (INIS)

    The usefulness of three-dimensional (3D) CT imaging of skeletal complications in hemodialysis patients was evaluated. In this study, CT HiLight Advantage from GE Medical Systems (Milwaukee, Wisconsin) was used. Since the 3D image can be manipulated in various ways, it is quite useful for the examination of anatomically complex areas such as hip joints and the spine. As a result, amyloid deposition in the femoral head and the pelvic bone, as well as a small pelvic fracture, were clearly demonstrated. Bone surface irregularity due to severe osteopenia was also evident with this method. 3D-CT imaging will enhance the accuracy of diagnoses of bone and joint diseases in hemodialysis patients.

    International Nuclear Information System (INIS)

    A pilot study was carried out to prospectively evaluate the efficacy and safety of Tenecteplase (TNKase) using a modified 'lyse and wait' technique with percutaneous transluminal angioplasty (PTA) to treat thrombosed hemodialysis arteriovenous grafts (AVG)s. Seven patients with eight hemodialysis AVGs were treated and followed up to 1 year. Dosing included 1 mg TNKase and 3,000-4,000 U of heparin. Technical and clinical success rates were 100% and 88%, respectively. No major complications occurred. Primary patency rates at 30, 90, and 180 days were 62%, 50%, and 33%, respectively. TNKase, used in this fashion, may be comparable to alteplase and reteplase for safe and effective thrombolysis of PTFE dialysis grafts

    Full Text Available Aim: The aim of the present study is to determine whether there are statistically differences between hemodialysis patients and control (healthy groups according to level of serum cadmium (Cd, total triiodothyronine (T3 and total thyroxine (T4 and adrenocorticotropin hormone (ACTH, and besides whether there are any correlation coefficients of trace element with thyroid profiles, ACTH in these groups. Material and Methods:The study included 47 hemodialysis patient who were dialyzed three times a week and each session was at least 4 hours. The duration of dialysis range were 2-16 yr. This group called as a “Hemodialyis group”. Blood samples were taken before (pre-hemodialysis and after (post-hemodialysis hemodialysis session. “Control group” included 23 healthy volunteers with no medical problem. In control group, samples were taken after 10 hour fasting. Results: Levels of total T3 were higher in group of control than the levels of pre-hemodialysis and post-hemodialysis (p?0.001. Total T3 levels were lower in pre-hemodialysis (p?0.05 than those of post-hemodialysis. The highest level of total T4 and lowest level of Cd were in control group and these parameters were statistically different from the pre-hemodialysis (respectively p?0.001, p?0.01. We did not determine any significant differences between all groups according to data of ACTH levels. Discussion: We suggest that analyzing the levels of Cd may be useful for the hemodialysis patients. But, we did not determine a significant association between Cd and thyroid profiles and ACTH levels.

    Full Text Available Abstract Background The relationship between intraocular pressure (IOP changes and hemodialysis has been evaluated for several decades. However, no report on an IOP rise in uveitis patients during hemodialysis has been previously documented. This report describes the case of an uveitis patient with repetitive IOP spikes associated with severe ocular pain during hemodialysis sessions, which resolved after glaucoma filtering surgery. Case presentation A 47-year-old male with diabetes and hypertension had complained of recurrent ocular pain in the left eye during hemodialysis sessions. A slit-lamp examination showed diffuse corneal epithelial edema with several white keratic precipitates and inflammatory cells (Grade 3+ in the anterior chamber of the left eye. No visible neovascularization or synechiae were visible on the iris or angle. Topical glaucoma eye-drops and intravenous mannitol before hemodialysis did not prevent subsequent painful IOP spikes in the left eye. At the end of hemodialysis, IOP averaged ~40 mmHg. After trabeculectomy with mitomycin C in the left eye, his IOP stabilized in the low-teens (range, 10–14 mmHg and no painful IOP spikes occurred during hemodialysis over the first postoperative year. Conclusion We present a case of recurrent painful IOP spikes during hemodialysis in a patient with unilateral anterior uveitis unresponsive to conventional medical treatment prior to hemodialysis. To our knowledge, this is the first case report of repetitive symptomatic IOP rise during hemodialysis in an uveitic glaucoma patient. This case highlights the importance of the awareness of the possibility that IOP may rise intolerably during hemodialysis in uveitis patients with a compromised outflow facility.

    Aside from a decrease in the high-density lipoprotein (HDL) cholesterol levels, qualitative abnormalities of HDL can contribute to an increase in cardiovascular (CV) risk in end-stage renal disease (ESRD) patients undergoing chronic hemodialysis (HD). Dysfunctional HDL leads to an alteration of reverse cholesterol transport and the antioxidant and anti-inflammatory properties of HDL. In this study, a quantitative proteomics approach, based on iTRAQ labeling and nanoflow liquid chromatography mass spectrometry analysis, was used to generate detailed data on HDL-associated proteins. The HDL composition was compared between seven chronic HD patients and a pool of seven healthy controls. To confirm the proteomics results, specific biochemical assays were then performed in triplicate in the 14 samples as well as 46 sex-matched independent chronic HD patients and healthy volunteers. Of the 122 proteins identified in the HDL fraction, 40 were differentially expressed between the healthy volunteers and the HD patients. These proteins are involved in many HDL functions, including lipid metabolism, the acute inflammatory response, complement activation, the regulation of lipoprotein oxidation, and metal cation homeostasis. Among the identified proteins, apolipoprotein C-II and apolipoprotein C-III were significantly increased in the HDL fraction of HD patients whereas serotransferrin was decreased. In this study, we identified new markers of potential relevance to the pathways linked to HDL dysfunction in HD. Proteomic analysis of the HDL fraction provides an efficient method to identify new and uncharacterized candidate biomarkers of CV risk in HD patients. PMID:22470525

    Full Text Available The aim of this study is to evaluate the prevalence of GI symptoms, endoscopic abnormalities, histologic gastritis and Helicobacter pylori infection in children with End Stage Renal Disease (ESRD undergoing maintenance hemodialysis. Upper endoscopy and gastric biopsy were performed in 31 consecutive ESRD children from 2002-2007, before renal transplantation. H. pylori status was determined by urease test and histology. The mean age of patients was 11 ±3.3 years (4-16 year. The mean duration of dialysis was 12.4 ±11 months (1.5-54 months. Seventeen patients (54.8% were symptomatic. Twenty patients (64.5% had endoscopic abnormalities. Antral erythema, esophagitis, antral nodularity and diffuse gastritis were common endoscopic findings. Endoscopic abnormalities were more common in symptomatic patients than asymptomatic patients (p<0.05. Twenty patients (64.5% were H. pylori positive. There was no statistical correlation between age, sex, serum creatinine level, presence of any symptoms and endoscopic abnormalities with H. pylori positivity. The mean duration of dialysis in H. pylori negative patients was significantly longer in comparison with H. pylori positive patients. High prevalence of eodoscopic abnormalities and H. pylori infection in both symptomatic and asymptomatic patients emphasize the necessity of upper GI evaluation in ESRD children before renal transplantation.

  5. The efficacy of carotid ultrasonography in estimating coronary artery stenosis in patients receiving hemodialysis

    International Nuclear Information System (INIS)

    In patients with dialysis therapy, cardiovascular diseases have a great impact on morbidity and mortality. Because physicians have recently been encountering more patients with diabetes mellitus as well as more elderly patients, the importance of evaluating atherosclerosis has continuously increased. It has been reported that ischemic heart diseases or cerebrovascular diseases can be estimated using non-invasive ultrasonography. In addition, we can also diagnose coronary stenosis using computed tomography more easily than before. In this study, we in vestigated the efficacy of carotid ultrasonography in estimating coronary artery stenosis in patients with hemodialysis. One hundred and eight patients (58 men and 50 women with a mean age of 69±12 years, and a mean dialysis duration of 6.7±6.2 years) were enrolled in this study. We measured the maximum intima-media thickness (max-IMT), the distribution and the properties of plaque and plaque scores at carotid arteries using ultrasonography, and examined the degree of stenosis and the number of stenotic coronary arteries using computed tomography. As the max-IMT or plaque scores increased, the degree of stenosis became significantly more severe and multi-vessel disease was observed with significantly greater frequency. End stage renal disease is one of most significant cardiovascular risk factors. However, it is difficult to diagnose ischemic heart disease correctly in these patients because they sometimes have few sympnts because they sometimes have few symptoms due to diabetes and often show atypical electrocardiograms due to ventricular hypertrophy or electrolyte disorders. In this study, we clearly showed the correlation between atherosclerosis in the carotid arteries and stenosis in the coronary arteries. It is suggested that carotid ultrasonography is useful to estimate coronary artery stenosis, and effective for evaluating the risk of ischemic heart diseases non-invasively in patients with hemodialysis.

    Full Text Available Introduction. The aim of this study was to evaluate the frequency of unexplained pulmonary hypertension (PHT among patients on hemodialysis at 2 centers and to evaluate possible predisposing factors.Materials and Methods. In this cross-sectional study, PHT was screened by Doppler echocardiography on the day after dialysis in 62 patients with end-stage renal disease receiving maintenance hemodialysis via arteriovenous access. Pulmonary hypertension was defined as a systolic pulmonary arterial pressure (PAP higher than 35 mm Hg, and the systolic PAP was calculated using the modified Bernoulli equation. Clinical variables were compared between patients with and without PHT.Results. A PAP higher than 35 mm Hg was found in 32 patients (49.3% receiving hemodialysis, with a mean systolic PAP of 39.58 ± 13.27 mm Hg. Blood hemoglobin level was significantly lower in the patients with PHT than those without PHT (9.8 ± 1.97 g/dL versus 11.07 ± 1.86 g/dL; P = .01. In addition, serum levels of albumin was lower in these patients (3.38 ± 0.32 g/dL versus 3.75 ± 0.44 g/dL; P = .02.Conclusions. This study demonstrates a surprisingly high prevalence of PHT among patients with end-stage renal disease receiving hemodialysis. We concluded that the best approach to this unrecognized complication that is associated with reduced survival is keeping it in mind and looking for it in the management of patients on dialysis.

    The clinical and epidemiological relevance of circulating antibodies to hepatitis C virus (HCV) in hemodialysis patients is uncertain, since clinical signs of infection are often mild or absent, with alanine aminotransferase (ALT) values that are virtually always normal, and liver biopsies are only rarely performed. Determination of HCV RNA in serum is therefore critical for distinguishing chronic HCV infection from previous exposure to the virus. We studied HCV viremia by reverse transcripti...

    2010-10-01

    Hemodialysis is associated with an increased risk of neoplasms which may result, at least in part, from exposure to ionizing radiation associated with frequent radiographic procedures. In order to estimate the average radiation exposure of those on hemodialysis, we conducted a retrospective study of 100 patients in a university-based dialysis unit followed for a median of 3.4 years. The number and type of radiological procedures were obtained from a central radiology database, and the cumulative effective radiation dose was calculated using standardized, procedure-specific radiation levels. The median annual radiation dose was 6.9 millisieverts (mSv) per patient-year. However, 14 patients had an annual cumulative effective radiation dose over 20 mSv, the upper averaged annual limit for occupational exposure. The median total cumulative effective radiation dose per patient over the study period was 21.7 mSv, in which 13 patients had a total cumulative effective radiation dose over 75 mSv, a value reported to be associated with a 7% increased risk of cancer-related mortality. Two-thirds of the total cumulative effective radiation dose was due to CT scanning. The average radiation exposure was significantly associated with the cause of end-stage renal disease, history of ischemic heart disease, transplant waitlist status, number of in-patient hospital days over follow-up, and death during the study period. These results highlight the substantial exposure to ionizing radiation in hemodialysis patients.

The objective of this study was to investigate whether the findings of bone marrow studies can predict mortality in chronic hemodialysis patients. Methods. Seventy-eight end-stage renal disease patients on maintenance hemodialysis underwent bone marrow biopsies between 2000 and 2011, with the most common indication being unexplained anemia followed by unexplained leukocytosis and leukopenia. Results. The survivors had a higher incidence of abnormal megakaryocyte distribution (P = 0.001), band and segmented cells (P = 0.021), and lymphoid cells (P = 0.029) than the nonsurvivors. The overall mortality rate was 38.5% (30/78), and the most common cause of mortality was sepsis (83.3%) followed by respiratory failure (10%). In multivariate Cox regression analysis, both decreased (OR 3.714, 95% CI 1.671–8.253, P = 0.001) and absent (OR 9.751, 95% CI 2.030–45.115, P = 0.004) megakaryocyte distribution (normal megakaryocyte distribution as the reference group), as well as myeloid/erythroid ratio (OR 1.054, CI 1.012–1.098, P = 0.011), were predictive of mortality. Conclusion. The results of a bone marrow biopsy can be used to assess the pathology, and, in addition, myeloid/erythroid ratio and abnormal megakaryocyte distribution can predict mortality in chronic hemodialysis patients.

  19. Complications of arteriovenous hemodialysis fistulas: angiographic findings and interventional treatments

    International Nuclear Information System (INIS)

    To analyze angiographic findings and to evaluate prognosis after interventional treatment of complication arteriovenous hemodialysis fistulas. We reviewed 19 patients of complicated arteriovenous hemodialysis fistulas between June 1993 and January 1995. The angiographic findings of 19 patients were analyzed and outcome and interventional treatment in 12 patients were evaluated. On angiography, there were 15 stenosis, 3 complete occlusion, and a poor arterialization of venous side. Two of there were combined with pseudoaneurym. Most common location and the lesion was cephalic vein (6/19) alone or with neighboring anastomosis(5/19). Other location included anastomosis(2/19), radial artery (1/19), radial artery with cephalic vein(2/19), and central vein(2/19). The percutaneous transluminal angioplasty was performed in 8 patients, thrombolysis in 3, and both procedures in 1. The overall success rate of the interventional treatment was 75%(8/12). It is suggested that the interventional procedures could replace the surgery as the primary choice for the treatment of complicated arteriovenous hemodialysis fistulas, considering its safety, high initial success rate and lower morbidity

    A 69-year-old Japanese man developed pruritus 3 years after beginning hemodialysis. Although eczema was not apparent at first, erythematous patches and plaques developed gradually on the affected skin. Secondary hyperparathyroidism was considered to be a main cause of this patient's pruritus, but skin lesions worsened even after parathyroidectomy had markedly decreased parathyroid hormone concentrations. Two months later, he developed an antibiotic-refractory fever of unknown origin and cervical, axillary, and inguinal lymphadenopathy. Elevations of soluble interleukin-2 receptor with 7410 U/mL and IgE with 24 600 U/mL in serum were noted, as was eosinophilia. The skin showed multiple slightly scaly patches and infiltrative plaques, which were reddish brown and distributed widely over the body surface except for the scalp and face. Mycosis fungoides, a cutaneous T-cell lymphoma, was diagnosed from biopsy specimens findings in skin and lymph node. Mycosis fungoides has not been documented as a cause of pruritus in hemodialysis patients. However, if skin lesions steadily worsen in hemodialysis patients, malignant diseases such as mycosis fungoides should be considered. PMID:16817798

    The aim of this study was to investigate the relationship between sleep disorders and C-reactive protein (CRP), hallmark of inflammation, and other biomarkers which may alter in hemodialysis patients. Our study included 108 patients who were dialyzed at least for 3 months. Before hemodialysis, blood samples were collected and serum levels of CRP, ferritin, albumin, phosphorus, parathyroid hormone, and hemoglobin were measured. Sleep disorders were confirmed by the presence of at least one of following criteria: insomnia, restless leg syndrome (RLS), obstructive sleep apnea syndrome (OSAS), narcolepsy, nightmare, sleepwalking, and poor sleep. 82.4% of patients demonstrated sleep disorders; insomnia (50%), RLS (32.4%), OSAS (7.4%), narcolepsy (15.7%), nightmare (15.7%), sleepwalking (0.9%), and poor sleep (71.3%). Our results revealed that CRP ?3.8 ?g/ml and advanced age were significantly associated with sleep disorders in these patients (p = 0.004 and p = 0.006, respectively). We concluded that inflammation has a close relation with sleep disorders in hemodialysis patients. PMID:22427289

    Objective The patient's clinical features at hemodialysis initiation can affect their prognosis in the subsequent dialysis period; however, these features have not been fully elucidated in very elderly subjects. The purpose of this study was to clarify the clinical characteristics associated with cardiovascular and chronic kidney disease at hemodialysis initiation. Methods Twenty consecutive very elderly patients with end-stage renal disease (ESRD) (?80 years; VE group) and 35 consecutive control patients with ESRD (AVC), mitral valve calcification and mitral annular calcification (MAC). Results The diastolic blood pressure was significantly lower and pulse pressure values were significantly higher in the VE group than in the control group, whereas the estimated glomerular filtration rate and cardiac function were comparable between the two groups. Despite having lower serum phosphate and calcium-phosphate product levels, the VE group exhibited more severe TAC, AVC and MAC than the control group. Furthermore, the duration of hospitalization was significantly shorter in the very elderly patients followed by nephrologists than in those who were not. Conclusion Our findings suggest that atherosclerotic lesions are more severe in very elderly patients at hemodialysis initiation. PMID:25786445

    Altered systemic iron metabolism is a key element of uremia, and functional iron deficiency mainly related to subclinical inflammation makes it difficult to maintain proper control of anemia in chronic hemodialysis patients (CHD). In the last decade, the hepatic hormone hepcidin has been progressively recognized as the master regulator of circulating iron levels through the modulation of cellular iron fluxes in response to iron stores, as well as to erythroid and inflammatory stimuli. Hepcidin is cleared by the kidney and progression of renal disease has been associated to increased serum hepcidin levels. This, in turn, reduces iron availability for erythropoiesis, suggesting anti-hepcidin strategies for improving anemia control. Moreover, hepcidin has been recently implicated in the pathogenesis of long-term complications of dialysis, like accelerated atherosclerosis. Initial studies almost invariably reported a sustained increase of serum hepcidin in chronic hemodialysis patients. Noteworthy, such studies included relatively few patients and controls that were poorly matched for major determinants of serum hepcidin at population level, i.e., age and gender. More recent data based on accurately matched larger series challenge the view that hepcidin is intrinsically increased in hemodialysis patients, showing a marked inter- and intra-individual variability of hormone levels. Here we take a critical look to the data published so far on hepcidin levels in CHD, analyze the reasons underlying the discrepancies in available studies and the hepcidin variability in CHD, and point out the need for further studies in large series of well-characterized CHD patients and controls.

  4. Thoracic CT findings in long-term hemodialysis patients

    International Nuclear Information System (INIS)

    Purpose: To evaluate thoracic CT findings of long-term hemodialysis patients. Material and methods: Thoracic CT findings of 117 umremic patients (61 men, 56 women) with complaints of cough, dyspnea, low-grade pyrexia, malaise, weight loss, and profuse perspiration were retrospectively documented. Results: Atelectasis (60%), cardiomegaly (60%), pleural effusion (51%), vascular congestion (44%), parenchymal consolidation (38%), parenchymal scarring-fibrosis (31%), and lymphadenopathy (29%) were the most common CT findings in the thoraces of the long-term hemodialysis patients. Staphylococcus aureus was detected in 13 patients (11%) who had parenchymal infiltration. Thoracid tuberculosis was identified in 15 patients (13%), 11 of these cases being confined to the lung parenchyma, 3 to the pleura, and 1 involving the pleura and pericardium. Conclusion: In patients under long-term hemodialysis treatment, parenchymal consolidation, secondary to infectious agents such as S. aureus and Mycobacterium tuberculosis, is the most important CT finding since these lesions can be detected and treated successfully if they are considered as etiologic factors early on.

    Full Text Available Abstract Background Onychomycosis has a high prevalance among immunocompromised patients such as diabetics and hemodialysis patients. In the present study, we aimed to investigate the prevalence of onychomycosis among hemodialysis patients with and without diabetes mellitus, and to find out the factors likely to be associated with the development of onychomycosis among hemodialysis patients. Methods One hundred and nine hemodialysis patients were enrolled. Fifty-seven of hemodialysis patients had the diagnosis of diabetes mellitus. Nail scrapings were obtained from 76 patients who had dystrophic nail changes. Samples were examined with 20% potassium hydroxide solution and all of the samples were inoculated on Saboraud's dextrose agar, potateus dextrose agar and mycobiotic agar. Diagnosis of onychomycosis was based on the presence of both positive clinical signs and positive potassium hydroxide test. Results Onychomycosis was diagnosed in 26.6% of hemodialysis patients. Diabetes mellitus was present in 68.9% of patients with onychomycosis. Toenail scraping cultures were reported to be positive in 19.7% of patients with dystrophic nail changes. Logistic regression analysis revealed that the presence of diabetes mellitus and the mean duration of hemodialysis were the significant predictors associated with the development of onychomycosis. Conclusion The prevalence of dystrophic nail changes and onychomycosis is increased among hemodialysis patients. The dialysis duration and the presence of diabetes mellitus are the independent risk factors associated with the development of onychomycosis in uraemic patients.

    Full Text Available Background/Aim. Chronic renal insufficiency (CRI, diabetes, hypertension, autosomal dominant polycystic kidney disease (ADPKD are the main reasons for starting dialysis treatment in patients having kidney function failure. At present, dialysis treatments are performed in about 4,100 patients at 46 institutions in Serbia, out of which 90% are hemodialyses. At end-stage renal disease (ESRD the only correct selection is kidney transplatation. The basic aim of the planned research was to compare ratio of costs and effects (Cost Effectiveness Analysis - CEA of hemodialysis and kidney transplantation in patients at ESRD. Methods. As the main issue of treatment in patients from both groups the life quality measured by the validated McGill Questionary, was used. The study included 150 patients totally, divided into two groups. The study group consisted of 50 patients with kidney transplantation performed at the Clinical Center of Serbia and the control group consisted of 100 patients on hemodialysis at Clinical Center of Serbia, Clinical Hospital Center Zemun, Clinical Hospital Center 'Zvezdara', Clinical Center Kragujevac and Health Center 'Studenica', Kraljevo, comparable with respect to sex, age and length of treatment with the study group. Results. Effect of kidney transplantation in relation to hemodialysis being selection of treatment is expressed in the form of incremental ratio of costs and effects (Incremental Cost-Effectiveness Ratio - ICER. It is clear from the enclosed tables that the strategy of kidney transplantation is far more profitable considering the fact that it represents saving of EUR 132,256.25 per one year of contribution Quality Adjusted Life Years (QALY within the period of 10 years. According to all aspects of live quality (physical symptoms and problems, physical well-being, psychological symptoms, existential well-being and support, difference is statistically important in favor of transplant patents. Conclusion. The costs of patient therapy by hemodialysis at end-stage renal disease is far greater than by performing therapy of transplantation and maintenance, by almost three and a half times. Difference in total quality aspects of human life (physical, emotional, social, spiritual and financial between dialyzed and transplant patients is statistically significant and by 18.12% greater in transplant patients than in patients on hemodialysis.

We evaluate the prevalence and predictive risk factors of depression in the Arab population undergoing HD in Nazareth, Israel.Methods: We conducted a prospective study that included 71 patients in the HD unit with a mean age of 61.9 ± 14.13 years who had undergone HD and 26 healthy control subjects with a mean age of 59.3 ± 7.3. Beck's Depression Inventory and Hamilton Depression Scale assessments were administered. Blood analysis for hematological and biochemical parameters was obtained. Diagnosis was made using the Diagnostic and Statistical Manual of Mental Disorders scale to correlate psychological variables with clinical, hematological, and biochemical parameters. Statistical analysis was carried out using analysis of variance followed by Tukey post-hoc multiple comparison tests.Results: The prevalence of depression was 43.7% in HD patients. Between HD patients and controls, cortisol values were 16.96 ± 0.5476 and 11.96 ± 1.116, respectively (P < 0.0001; 95% confidence intervals [CI]: 2.416–6.825.

Hematological and biochemical parameters were compared between depressed HD and nondepressed patients, but differences between the two groups were found to be insignificant (P > 0.05.Conclusion: Our HD patients were severely depressed. Studies of glucocorticoid turnover activity such as cortisol, a potent chemical stress hormone, may be used as a model and marker for early diagnosis of depression among HD patients. The strong familial support system in Arabic traditions has failed to decrease depression among these patients.Keywords: Beck Depression Inventory, cortisol, depression, hemodialysis

    The kidneys of patients with chronic renal failure undergoing maintenance hemodialysis may show different variances or complications. Most common are secondarily acquired renal cysts, which my be found in as many as 92% of patients after 8 years of hemodialysis. Single (in 12.5% of patients) or multiple (8.3%) cysts with bleeding are common; additionally, hematuria or ruptured cysts may be found. Bleeding into cysts is more common in patients with autosomal dominant polycystic kidney disease. Due to the decreasing urinary production development of kidney stones is very uncommon, but calcification in or around cysts can be found in 71% of patients. Kidney tumors occur 41 times more often in patients with chronic renal failure than in patients without kidney disease. We detected tumors in 4.2% of our patients on long-term dialysis. Diagnostic differentiation of the relatively slow growing and fairly late metastasizing malignant tumors from adenomas is not possible. Nevertheless, we screen our patients every 3-4 years. Computed tomography is superior to ultrasonography for this purpose, because ultrasonography lacks the necessary sensitivity in this group of patients. (orig.) [Deutsch] An den Nieren von Patienten mit terminaler Niereninsuffizienz unter chronischer Haemodialyse koennen unterschiedliche Veraenderungen oder Komplikationen auftreten. Am haeufigsten sind sekundaere, erworbene Nierenzysten, die nach achtjaehriger Dialysedauer bei 92% der Patienten gefunden werden. Solitaere (bei 12,5% der Patienten) sowie multipel (8,3%) eingeblutete Nierenzysten sind haeufige Befunde, darueber hinaus kann es zu einer Haematurie oder zur Zystenruptur kommen. Hierbei sind Einblutungen bei Patienten mit familiaeren Zystennieren haeufiger und koennen dann auch multilokulaer auftreten. Konkremente der Nieren sind aufgrund der zunehmenden Oligurie selten, Verkalkungen im Bereich der Nierenzysten und Matrixsteine finden sich allerdings bei ca. 71% der Patienten. Tumoren sind 41fach haeufiger als bei Nierengesunden, im eigenen Kollektiv fanden sie sich bei 4,2% der Langzeitdialysepatienten. Differentialdiagnostisch koennen die relativ langsam wachsenden und spaet metastasierenden malignen Tumoren von den haeufiger auftretenden Adenomen nicht unterschieden werden. Dennoch fuehren wir ein regelmaessiges Screening im Abstand von drei bis vier Jahren mittels Computertomographie durch, da die Sonographie bei diesen Patienten nicht ausreichend sensitiv ist.

MÉTODOS: Sessenta pacientes consecutivos com DRC em tratamento hemodialítico foram avaliados clinicamente e submetidos ao ecodopplercardiograma, sendo acompanhados durante 19 ± 6 meses. Os desfechos avaliados foram eventos cardiovasculares fatais e não fatais e mortalidade geral. O valor preditivo das variáveis ecocardiográficas foi avaliado pelo modelo de regressão de Cox, as curvas de sobrevida foram construídas pelo método de Kaplan-Meier e o teste log rank foi utilizado para compará-las. RESULTADOS: As taxas de sobrevida livre de eventos cardiovasculares, de mortalidade cardiovascular e de mortalidade global em dois anos foram de 79,4%, 88,5% e 83%, respectivamente. Diabetes, diagnóstico prévio de doença cardiovascular (DCV), fração de ejeção, fração de encurtamento, diâmetro sistólico do ventrículo esquerdo e relação E/e' foram preditores de desfecho cardiovascular na análise univariada. Na análise multivariada, história prévia de DCV (HR = 6,17; IC 95% 1,7 - 22,2; p = 0,005) e disfunção diastólica moderada a grave (HR = 3,76; IC 95% 1,05 - 13,4; p = 0,042) foram fatores de risco independentes para eventos cardiovasculares. CONCLUSÃO: Disfunção diastólica de moderada a grave é um preditor independente de eventos cardiovasculares em pacientes em hemodiálise. Abstract in english BACKGROUND: Patients with chronic kidney disease (CKD) on hemodialysis have high rates of cardiovascular morbidity and mortality. Although structural and functional echocardiographic alterations in patients undergoing hemodialysis have been the subject of several survival analysis studies, the progn [...] ostic value of these alterations is not well established in literature. OBJECTIVE: To determine the prognostic value of echocardiographic parameters in patients with CKD on hemodialysis. METHODS: Sixty consecutive patients with CKD on hemodialysis were clinically evaluated and underwent Doppler echocardiography, being followed for 19 ± 6 months. The outcome measures were fatal and nonfatal cardiovascular events and overall mortality. The predictive value of echocardiographic variables was evaluated by Cox regression model and survival curves were constructed using the Kaplan-Meier method and log rank test to compare them. RESULTS: Rates of survival free of cardiovascular events, of cardiovascular and overall mortality in two years were 79.4%, 88.5% and 83% respectively. Diabetes, previous diagnosis of cardiovascular disease (CVD), ejection fraction, fractional shortening, left ventricular systolic diameter and E/e' ratio were predictors of cardiovascular outcome at univariate analysis. In the multivariate analysis, previous history of CVD (HR = 6.17, 95%CI: 1.7 - 22.2, p = 0.005) and moderate to severe diastolic dysfunction (HR = 3.76, 95%CI: 1.05 - 13.4, p = 0.042) were independent risk factors for cardiovascular events. CONCLUSION: Moderate to severe diastolic dysfunction is an independent predictor of cardiovascular events in hemodialysis patients.

  17. Contributions of myocardial scintigraphy in coronary heart disease in chronic hemodialysis: A prospective study of 52 cases

    International Nuclear Information System (INIS)

    We propose in this work to assess the prevalence of cardiovascular risk factors in the chronic hemodialysis as well as diagnostic and prognostic performance of myocardial SPECT. We conducted a prospective study over a period of 5 years (1999-2004) assemble 52 chronic hemodialysis patients, 73 pour cent were treated at the hemodialysis unit of the principal Hospital Military - Tunis and 27 pour cent the hemodialysis unit of the polyclinic CNSS El Khadhra. The conventional periodic hemodialysis bicarbonate was the dialysis technique used in all our patients.

  18. Effect of Hemodialysis on Left and Right Ventricular Volume and Function

    International Nuclear Information System (INIS)

    With the improvement of hemodialysis, the course of thc discase in patient with endstage renal disease has been clearly improved. Nevertheless, among several shortcomings to our present mode of renal replacement therapy, cardiovascular complications have been the leading cause of morbidity and mortality. Several factors such as anemia, arteriovenous shunting of blood, intermittent extracorporeal circulation and hypertension may be contributing. But little is known about the quantitative cardiac hemodynamic characteristics occurred during hemodialysis. The purpose of this study is to observe the sequential hemodynamic changes before, during and after the hemodialysis and to investigate: reliable parameters in the detection of ventricular dysfunction. In the present study, equilibrium radionuclide cardiac angiography was performed and left and right ventricular volume indices, ejection phase indices of both ventricular, performance were measured in the 16 stable patients with chronic renal failure treated with maintenance hemodialysis sequentially i.e. before, during (carly and late phase) and after the hemodialysis. The results obtained were as follows; 1) The indices of the left ventricular function were not changed during the hemodialysis but increased after the hemodialysis. 2) The indices of the right ventricular function(EF, SVI) were significantly decreased in the early phase (15, 30 minutes after starting extracorporeal circulation) but recovered after the hemodcirculation) but recovered after the hemodialysis, 3) The ratio of right ventricular to left ventricular ejection fraction was significantly decreased in the early phase and the lung volume indices were significantly increased at the same phase. As a conclusion, hemodialysis improves left ventricular function maybe du to increased contractility, and effects on the right ventricular function maybe due to the increased lung volume in the early phase of hemodialysis.

    Caspofungin pharmacokinetics was assessed in 27 critically ill patients, including 7 on continuous venovenous hemofiltration (CVVH), 8 on continuous venovenous hemodialysis (CVVHD), and 13 not requiring continuous renal replacement therapy (CRRT). Caspofungin exposure during CRRT was very similar to that of the control group and comparable to that in healthy volunteers. Caspofungin clearance by CRRT was very low. Therefore, the standard dosage of caspofungin is probably adequate for criticall...

    Full Text Available Background: Patients undergoing hemodialysis (HD have low plasma levels of zinc (Zn, high plasma levels of copper (Cu, and exhibit increased oxidative stress, inflammation, and immune abnormalities. We evaluated the effects of Zn supplementation on abnormal plasma Cu/Zn ratios and clinical outcomes in HD patients.Design and Methods: Patients on long-term HD with lower than normal plasma concentrations of Zn (< 80 mg/dL were randomized to receive daily oral Zn supplements (n = 40 or no supplements (n = 25 for eight weeks. Age- and sex-matched healthy individuals served as a control group (n = 38. A number of clinical parameters were measured before and after the supplementation period.Results: Compared with healthy subjects, patients had significantly elevated plasma Cu concentrations and Cu/Zn ratios, as well as higher levels of oxidative stress and pro-inflammatory cytokines. Patients who received Zn supplements for eight weeks had higher plasma concentrations of Zn and lower concentrations of Cu, along with reduced Cu/Zn ratios, oxidative stress status, and inflammatory responses compared to patients who did not receive Zn. Patients receiving Zn also showed significantly higher percentages of CD4 and CD19 lymphocytes, and elevated CD4/CD8 ratios.Conclusions: Zn supplementation ameliorates abnormally high plasma Cu/Zn ratios and may reduce oxidative stress, improve inflammatory status, and maintain immune function in patients undergoing long-term HD.

  2. Advantage of 123I-BMIPP myocardial scintigraphy for assessing coronary artery disease in maintenance hemodialysis patients

    International Nuclear Information System (INIS)

    Coronary artery disease (CAD) contributes to high mortality rate in end-stage renal disease (ESRD) patients. Single photon emission computed tomography (SPECT) using 201Thallium (Tl) or 99mTechnetium-labeled tracers has been used to detect CAD, but they require physical or pharmacological stress loading. Resting SPECT using an iodinated fatty acid analogue, 15-(p-[I-123]-iodophenyl)-3-(R,S) methylpentadecanoic acid (123I-BMIPP), can assess fatty acid metabolism in the myocardium. We investigated the ability of 123I-BMIPP SPECT to detect CAD in hemodialysis patients, and compared with 201Tl SPECT. We prospectively enrolled 130 ESRD patients undergoing hemodialysis with a mean duration of 88.6 months (male/female 77/53, mean age 63.8 years). Dual SPECT using 123I-BMIPP and 201Tl was performed, which was followed by coronary angiography (CAG). SPECT imaging was evaluated and graded in 17 segments using a five-point scale (0=normal, 4=absence). Final assessment was based on the summed score. On CAG, 71.5% of patients (93/130) showed a significant coronary stenosis (?75%), and 5 patients showed coronary spasm without coronary stenosis. When a BMIPP summed score of 6 or more was defined as abnormal. Its sensitivity, specificity, and accuracy for detecting CAD by BMIPP SPECT were 98.0, 65.6, and 90.0%, respectively. In contrast, these parameters for detecting CAD by Tl SPECT were 84.7, 46.9, and 7g CAD by Tl SPECT were 84.7, 46.9, and 75.0%, respectively, when a Tl summed score of 1 or more was defined as abnormal. In receiver operating characteristic (ROC) analysis, the area under the curve indicating the ability diagnose CAD was 0.895 in BMIPP and 0.727 in Tl SPECT. Resting BMIPP SPECT imaging is superior to Tl SPECT for detecting coronary lesions, and provides safe screening for CAD among maintenance hemodialysis patients. (author)

    Blood color of dialysis patients can be seen routinely. Darkened blood color is often observed in critically ill patients generally because of decreased oxygen saturation, but little is known about the other factors responsible for the color intensity. In addition, quantitative blood color examination has not been performed yet. Therefore, no one has evaluated the predictive power of blood color. The aim of this study was to evaluate if blood color darkness reflects some medical problems and is associated with survival disadvantage. Study design is a prospective cohort study. One hundred sixty-seven patients were enrolled in this study. Quantification of blood color was done using a reflected light colorimeter. Demographic and clinical data were collected to find out the factors that can be related to blood color. Follow-ups were performed for 2 years to analyze the risk factors for their survival. Regression analysis showed that C-reactive protein and white blood cell count were negatively correlated with blood color. In addition, blood color was positively correlated with mean corpuscular hemoglobin concentration and serum sodium concentration as well as blood oxygen saturation. During a follow-up, 34 (20.4%) patients died. Cox regression analysis revealed that darkened blood color was an independent significant risk factor of mortality in hemodialysis patients as well as low albumin and low Kt/V. These results suggest that inflammation independently affects blood color and quantification of blood color is useful to estimate prognosis in patients undergoing hemodialysis. It is possible that early detection of blood color worsening can improve patients' survival. PMID:22845854

    Short Form 36 (SF-36) is a well-documented health-related quality-of-life (HRQOL) instrument consisting of 36 questions compressed into eight scales and two primary dimensions: the physical and mental component scores. This tool was used to evaluate QOL among peritoneal dialysis (PD) and hemodialysis (HD) patients. The results of 16,755 HD and 1,260 PD patients (728 continuous ambulatory PD [CAPD] and 532 continuous cycling PD [CCPD]) completing an SF-36 during 1996 were analyzed. Three analyses of variance were performed, consisting of (1) no adjustment, (2) case mix (age, sex, race, and diabetes), and (3) case mix plus laboratory parameters. PD patients were younger (P CCPD than CAPD patients (P CCPD than CAPD patients. HD and CAPD scores were similar. CCPD patients perceived themselves as more physically impaired but better adjusted than HD or CAPD patients. These descriptive data show that perception of QOL among PD and HD patients is similar before adjustment, but PD patients score higher for mental processes with adjustment. CCPD patients score worse for physical function and better for mental function than either CAPD or HD patients. We cannot, however, exclude the influence of therapy selection. PMID:10676729

    Anticoagulation is required during hemodialysis to prevent thrombus formation within the extracorporeal circuit. The low-molecular-weight heparin tinzaparin is more expensive than unfractionated heparin (UFH) in Canada but more convenient to administer. We conducted a time-and-motion study to test the hypothesis that tinzaparin may reduce nursing time and total health care costs compared with UFH. Data on health care resource use associated with anticoagulation during hemodialysis for chronic renal failure were collected at an academic hospital in Quebec. Nursing time was recorded for 8 nurses performing 16 dialysis sessions for 4 patients receiving tinzaparin and 4 receiving UFH (2 dialysis sessions per patient). Nurses had ? 1 year of experience supervising hemodialysis. We estimated total annual costs of nursing time and health care resources (anticoagulants, medical supplies, and laboratory testing) associated with anticoagulation. In sensitivity analyses, drug costs were varied ± 30% of their base-case values. Estimated annual nursing times per patient were 0.8 vs. 11.5 hours in the first year and 0.6 vs. 10.2 hours in subsequent years for tinzaparin vs. UFH, respectively. Annual drug costs per patient were CAD 898.56 for tinzaparin and 546.75 for UFH. Estimated total annual costs were CAD 1061.03 vs. 1012.71 in the first year and CAD 917.75 vs. 895.23 in subsequent years for tinzaparin vs. UFH, respectively. Use of tinzaparin was cost saving relative to UFH if tinzaparin price was reduced 30%. Most of the price differential between tinzaparin and UFH is offset by substantial time savings to nephrology nurses. PMID:21338468

    Restless legs syndrome (RLS) is a common sleep disorder that can present secondary to medical conditions such as renal failure. This study aimed to evaluate RLS frequency and its related factors in chronic renal failure patients treated with hemodialysis. In a cross-sectional design, 163 patients with chronic renal failure were consecutively enrolled from hemodialysis center at Rasool-Akram hospital. Demographics, clinical and laboratory data were recorded. Patients were screened for presence and severity of RLS according to the four International Restless Legs Syndrome Group (IRLSSG) diagnostic criteria and severity scale. Patients with and without RLS were compared using SPSS statistical software (Version 16.0). Sixty-one patients (37.4 %) were diagnosed with RLS. Mean age in RLS group was significantly higher (65.2 ± 9.3 years) than RLS-negative group (59.0 ± 14.7 years; P = 0.004). Serum creatinine level was significantly higher in patients with RLS (7.6 ± 2.1 mg/dl vs. 6.7 ± 1.8 mg/dl; P = 0.009). Glomerular filtration rate in RLS patients was lower than other patients (9.2 ± 3.1 ccs/min vs. 11.6 ± 4.8 ccs/min; P = 0.0001). Patients with RLS had shorter sleep duration, and higher incidence of insomnia, daytime sleepiness, and sedative-hypnotic medication usage (P < 0.05). There was no significant difference between RLS-positive and RLS-negative patients in terms of renal failure pathology, dialysis frequency per week, dose of dialysis, duration of dialysis, renal transplantation, and history of diabetes and hypertension. Hemodialysis patients have a high prevalence of RLS which deserves special attention and specific treatment. PMID:25471049

    The aim of this study is to describe the characteristics of caregivers of chronic hemodialysis patients, assess their perceived burden and health-related quality of life, and investigate factors influencing this burden. We studied 100 hemodialysis patients and their respective primary caregivers for more than 4 months, measuring quality of life by the Medical Outcomes Survey 36-Item Short-Form Health Survey (SF-36). Subjective burden on caregivers was assessed by the Caregiver Burden scale (score range, 1 to 4; higher values indicate a greater effect). The majority of caregivers were women (84%), married (66%), with a mean age of 46 +/- 2 (SE) years, and of low socioeconomic level. Their main types of relationship with patients were wives (38%) and sons or daughters (27%). Caregiver Mental Health and Vitality were the most affected emotional dimensions on the SF-36 (mean scores, 64.4 +/- 1.8 and 66.6 +/- 1.7, respectively). Mean score of total burden experienced was 2.07 +/- 0.05. Multiple regression analysis showed that independent and significant predictors of burden were Mental Health of the caregiver (R2 = 24%), Vitality of the patient (R2 = 10%), type of relationship of the caregiver (female spouse) (R2 = 5%), and Pain of the caregiver (R2 = 3%). Caregivers of hemodialysis patients may experience a significant burden and an adverse effect on their quality of life. Emotional aspects of caregivers (particularly female spouses) and patients are important predictors of burden. Social support and psychological interventions should be considered to improve caregiver life and patient outcomes. PMID:11920347

    Full Text Available As a consequence of the proinflammatory environment occurring in dialytic patients, cytokine overproduction has been implicated in hemodialysis co-morbidity. However, there are discrepancies among the various studies that have analyzed TNF-alpha synthesis and the presence of peripheral blood mononuclear cell (PBMC priming in this clinical setting. We measured bioactive cytokine by the L929 cell bioassay, and evaluated PBMC TNF-alpha production by 32 hemodialysis patients (HP and 51 controls. No difference in TNF-alpha secretion was observed between controls and HP (859 ± 141 vs 697 ± 130 U/10(6 cells. Lipopolysaccharide (5 µg/ml did not induce any further TNF-alpha release, showing no PBMC priming. Paraformaldehyde-fixed HP PBMC were not cytotoxic to L929 cells, suggesting the absence of membrane-anchored TNF-alpha. Cycloheximide inhibited PBMC cytotoxicity in HP and controls, indicating lack of a PBMC TNF-alpha pool, and dependence on de novo cytokine synthesis. Actinomycin D reduced TNF-alpha production in HP, but had no effect on controls. Therefore, our data imply that TNF-alpha production is an intrinsic activity of normal PBMC and is not altered in HP. Moreover, TNF-alpha is a product of de novo synthesis by PBMC and is not constitutively expressed on HP cell membranes. The effect of actinomycin D suggests a putative tighter control of TNF-alpha mRNA turnover in HP. This increased dependence on TNF-alpha RNA transcription in HP may reflect an adaptive response to hemodialysis stimuli.

  10. Nonoxidized, biologically active parathyroid hormone determines mortality in hemodialysis patients

    Tepel, Martin; Armbruster, Franz Paul

    2013-01-01

    Background: It was shown that nonoxidized PTH (n-oxPTH) is bioactive, whereas the oxidation of PTH results in a loss of biological activity. Methods: In this study we analyzed the association of n-oxPTH on mortality in hemodialysis patients using a recently developed assay system. Results: Hemodialysis patients (224 men, 116 women) had a median age of 66 years. One hundred seventy patients (50%) died during the follow-up period of 5 years. Median n-oxPTH levels were higher in survivors (7.2 ng/L) compared with deceased patients (5.0 ng/L; P = .002). Survival analysis showed an increased survival in the highest n-oxPTH tertile compared with the lowest n-oxPTH tertile (?(2), 14.3; P = .0008). Median survival was 1702 days in the highest n-oxPTH tertile, whereas it was only 453 days in the lowest n-oxPTH tertile. Multivariable-adjusted Cox regression showed that higher age increased odds for death, whereas higher n-oxPTH reduced the odds for death. Another model analyzing a subgroup of patients with intact PTH (iPTH) concentrations at baseline above the upper normal range of the iPTH assay (70 ng/L) revealed that mortality in this subgroup was associated with oxidized PTH but not with n-oxPTH levels. Conclusions: The predictive power of n-oxPTH and iPTH on the mortality of hemodialysis patients differs substantially. Measurements of n-oxPTH may reflect the hormone status more precisely. The iPTH-associated mortality is most likely describing oxidative stress-related mortality.

    Full Text Available The repercussions of secondary hyperparathyroidism on the nutritional status of chronic renal failure patients have not been well established. Therefore, the aim of this study was to compare the nutritional indices of hemodialysis patients with and without secondary hyperparathyroidism. Sixteen hemodialysis patients with serum parathyroid hormone (PTH levels higher than 420 pg/ml (hyperparathyroidism group were matched for gender, age and length of dialysis treatment to 16 patients with serum PTH between 64 and 290 pg/ml (control group. The following parameters were assessed: anthropometric indices (body mass index, skinfold thickness, midarm muscle circumference and body fat, 4-day food diaries, protein catabolic rate, biochemical indices (blood urea nitrogen, serum creatinine, albumin, ionized calcium, inorganic phosphorus, serum alkaline phosphatase, PTH, pH and HCO3 and dialysis efficiency. We did not observe differences in the anthropometric indices between the two groups. Only calcium intake was significantly different between groups (307.9 mg/day for the hyperparathyroidism group vs 475.8 mg/day for the control group. Protein catabolic rate tended to be higher in the hyperparathyroidism group compared to the control group (1.3 vs 0.9 g kg-1 day-1; P = 0.08. Except for blood urea nitrogen (86.4 vs 75.7 mg/dl, alkaline phosphatase (175 vs 65 U/l and PTH (898 vs 155 pg/ml, no other differences were found between groups in the biochemical indices studied. PTH was directly correlated with protein catabolic rate (r = 0.61; P<0.05 and length of dialysis (r = 0.53; P<0.05 only in the hyperparathyroidism group. Considering the indices used, we could not demonstrate the deleterious effect of high PTH levels on the nutritional status of hemodialysis patients. Indirect evidence, however, suggests an action of PTH on protein metabolism.

  12. Central Venous Disease in Hemodialysis Patients: An Update

    International Nuclear Information System (INIS)

    Central venous occlusive disease (CVD) is a common concern among the hemodialysis patient population, with the potential to cause significant morbidity. Endovascular management of CVD, comprising percutaneous balloon angioplasty and bare-metal stenting, has been established as a safe alternative to open surgical treatment. However, these available treatments have poor long-term patency, requiring close surveillance and multiple repeat interventions. Recently, covered stents have been proposed and their efficacy assessed for the treatment of recalcitrant central venous stenosis and obstruction. Moreover, newly proposed algorithms for the surgical management of CVD warrant consideration. Here, we seek to provide an updated review of the current literature on the various treatment modalities for CVD

    Of 315 patients with permanent vascular hemodialysis access, 23 (7,3%) patients developed pyoinflammatory complications in various terms after the operation. Angiogenic sepsis was registered in 73,9% of them. Lethality among patients with pyoinflammatory complications of the vascular access was 69,6%. Gram-positive polyresistant microorganisms were predominantly defined. Clinical features of the pyoinflammatory process in the category of patients were: typical picture of phlegmon or infiltration in 50%; latent laboratory and clinical signs of the systemic inflammatory response. The above features and immunodeficiency defined late diagnostics and antibioticotherapy and, therefore, high lethality level in that category of patients. PMID:19668134

To be able to plan the treatment of this pathology, we must have reliable and updated information through health network which represents the best mean for planning and reflexion locally and nationwide. The aim of our study was to answer to this need through a local registry of renal replacement therapy and nephrology network that we have for the first time an inventory of this pathology in an Algerian town (Constantine), and in this article we present the first results concerning patients under chronic hemodialysis.

    Full Text Available Introduction. Patients on hemodialysis are a high-risk group for human T-lymphotropic virus 1 (HTLV1 infection and other viruses transmitted by blood or blood products. The Razavi and South Khorasan provinces in Iran are the endemic areas for  this virus. This study compares proviral load of HTLV1 in patients on hemodialysis with otherwise healthy carriers of HTLV1. Materials and Methods. In this case-control study  the proviral load of  the HTLV1 virus was compared between 25 patients on long-term hemodialysis who were positive for HTLV1 and 25  healthy carriers of HTLV1, to determine the effect of uremia and chronic hemodialysis on the proviral load. Virus proviral load was determined using a real-time polymerase chain reaction method. Results. There was a significant difference in the proviral load between the hemodialysis patients and the control group (903 ± 182 copies per mL versus 117 ± 186 copies per mL, respectively; P = .008. No significant correlation was found between the proviral load and    haematocrit or serum levels of urea, creatinine, parathyroid  hormone, calcium , and phosphorus  level in hemodialysis patients, but proviral load of HTLV1 was significantly correlated with leukocyte count (r = -0.46, P = .02, hemodialysis duration (r = 0.48, P = .02, and the numbers of blood transfusions (r = 0.71, P Conclusions. The immune deficiency related to end-stage renal disease and uremia is the probable cause of significantly higher HTLV1 proviral load in hemodialysis patients compared to healthy HTLV1 carriers. This high HTLV1 proviral load might be due to immune dysfunction in chronic hemodialysis patients.

    Full Text Available The National Institutes of Health (NIH sponsored HEMO Study did not demonstrate that an increase in dialysis dose was associated with an improvement in patient mortality rates. Despite this negative result, there is ongoing interest in determining if still higher doses of dialysis may be of benefit to patients receiving chronic hemodialysis therapy. Testing this hypothesis requires the use of more fre-quent hemodialysis and/or a much longer duration for each dialysis session. "Short daily hemodialysis", actually six times per week hemodialysis for 1.5 to 3 hours per session, provides a significant increase in small molecule clearance as measured by urea kinetics. "Long nocturnal daily hemodialysis", actually six times per week hemodialysis for 6-8 hours per session, provides a significant increase in both small and large molecular weight clearance and often alleviates the need to take phosphate binders. Both forms of more frequent dialysis have been shown to improve control of blood pressure. One small randomized trial of nocturnal versus conventional home dialysis showed a decrease in left ventricular (LV mass at 6 months in the nocturnal arm only. Most clinical trials conducted in these dialysis modalities have been observational trials and have enrolled small numbers of patients. The National Institutes of Health is sponsoring two clinical trials via the Frequent Hemodialysis Network to determine the effect of these two more frequent dialysis modalities on intermediate outcomes. In the short daily study, 250 patients will be randomized to receive either six times per week HD, with a session length of 1.5 to 2.75 hours, or conventional in-center hemodialysis. In the nocturnal study, 150 patients will be randomized to receive either six times per week overnight dialysis, with a session length of at least 6 hours, or conventional home hemodialysis.

  20. Loss of thyroid hormones in feces in children on regular hemodialysis

    International Nuclear Information System (INIS)

    In 20 children on hemodialysis in vitro tests of thyroid function were made. Total T4, free T4 and total T3 were below the normal mean. The daily loss of T3 into feces was significantly higher in dialysis children than in healthy controls. The amount of hormonal iodine loss into feces was calculated. It was significantly higher in children on hemodialysis than in controls. It is concluded that the loss of thyroid hormones into feces is the major cause of low serum thyroid hormone levels in children on hemodialysis. (orig.)

    Full Text Available Introduction. One of the most common complaints in patients with end-stage renal disease (ESRD is uremic pruritus. In the recent years, many drugs have been proposed for its treatment which have had paradoxical outcomes. We studied the antipruritus effect of montelukast sodium, a leukotriene receptor antagonist, in patients on hemodialysis.Materials and Methods. The study was conducted as randomized, single-blind, placebo-controlled crossover study in 5 hemodialysis centers. Sixteen patients with refractory pruritus were selected and were divided into 2 groups to receive firstly montelukast and then placebo, or vice versa. Patients were treated by montelukast tablets, 10 mg daily, for 20 days and the washout period was 14 days.Results. Of 16 patients whom were included in the study, 1 died during the placebo period of myocardial infarction and another patient who received montelukast for 20 days faced hemoglobin decrease during the placebo period diagnosed as myelodysplastic syndrome. At the end of the treatment with montelukast, pruritus was reduced by 35% (95% CI, 9.5% to 62.5%, while it was reduced 7% (95% CI, 0.5% to 15.9% with placebo (P = .002. The patients’ compliance was assessed satisfactory, except for 1 patient who exited the study due to anemia.Conclusions. Montelukast is more effective than placebo in the treatment of uremic pruritus not responding to the currently available antipruritus drugs, and it can be considered as a new and rather safe and effective treatment option in uremic patients.

  3. Cerebral microbleeds and intracerebral hemorrhages in patients on maintenance hemodialysis

    International Nuclear Information System (INIS)

    Cerebrovascular diseases are important causes of death in patients on maintenance hemodialysis. Recently, it has become clear that the presence of cerebral microbleeds (MBs) on T2*-weighted magnetic resonance imaging (MRI) is closely related to intracerebral hemorrhages. This study investigated the incidence of MBs in chronic dialysis patients and prospective hemorrhagic complications of chronic dialysis patients with old intracerebral hemorrhages. Eighty patients (34 males, 46 females) with chronic renal failure, whose mean age was 62.9±11.4 years, were examined by MRI. The mean duration of hemodialysis was 7.8±6.3 years. MBs were found in 28 patients (35%) by T2*-weighted MRI. Old intracerebral hemorrhages were seen in seven of the patients, and MBs were found in five (71%) of these seven patients. The frequency of old intracerebral hemorrhages was significantly higher in patients with MBs than in those without (p=0.048), and the numbers of MBs were significantly larger in patients with old intracerebral hemorrhages than in those without (p=0.0065). Three of the seven patients with old intracerebral hemorrhages had new hemorrhagic complications (two intracerebral hemorrhages and one cerebral microbleed) within a year. These intracerebral hemorrhages occurred in areas without MBs on the first T2*-weighted MRI. T2*-weighted MRI is useful for the detection of MBs, which may be a predictor of intracerebral hemorrhage. When actor of intracerebral hemorrhage. When a patient has a large number of MBs and old intracerebral hemorrhages, the risk of intracerebral hemorrhage undoubtedly increases. (author)

    Full Text Available This study aims to evaluate the laboratory variables in Iranian hemodialysis pa-tients. We studied 338 patients in 6 dialysis centers around the country. Sixty four percent of the patients were anemic, and the mean of hemoglobin levels in the patients was 9.6 ± 1.9 g/dL. Women had a significantly higher prevalence of anemia (p= 0.004; however, considering the absolute hemoglobin values, there was no significant difference between genders (p> 0.05. The mean urea reduction ratio (URR and Kt/V in the patients were 62.6 ± 12.8 and 1.17 ± 0.31, respectively. Hyperphosphatemia and hyperkalemia were observed in 50% and 58%, respectively. We conclude that our study demonstrated a relatively high prevalence of anemia and hyper-phosphatemia, however, a surprisingly good dialysis urea clearance in the Iranian hemodialysis patients. We should exploit more effort to maintain hemoglobin and serum phosphate levels with-in the target ranges.

  5. Spironolactone in chronic hemodialysis patients improves cardiac function

    International Nuclear Information System (INIS)

    We performed this study to assess whether low dose spironolactone could be administered in hemodialysis (HD) patients with moderate to severe heart failure to improve cardiovascular function and reduce hospitalization without inducing hyperkalemia. We enrolled 16 chronic HD patients with moderate to severe heart failure and left ventricle ejection fraction :5 45%. In a double blinded randomized placebo controlled study, one group of 8 patients received 25 mg of spironolactone after each dialysis session within six months, and the rest received a placebo. Echocardiography was performed on all the patients to assess ejection fraction and left ventricular mass during 12 hours after completion of hemodialysis at the beginning and the end of study. Serum potassium was measured predialysis every 4 weeks. The mean ejection fraction increased significantly more in spironolactone group during the study period than in the placebo group (6.2 + - 1.64 vs. 0.83 + - 4.9, P0.046). The mean left ventricular mass decreased in the spironolactone group, but increased significantly in the placebo group during the period (-8.4 + - 4.72 vs. 3 + -7.97. 95%, P= 0.021). The incidence of hyperkalemia was not significantly increased in the study or controlled groups. In conclusion, we found in this study that administration of spironolactone in chronic HD patients with moderate to severe heart failure substantially improved their cardiac function and decreases left ventricular mass without devecreases left ventricular mass without development of significant hyperkalemia.

    Vascular access thrombosis is the most common and costly complication in hemodialysis patients. The role of thrombophilia in access thrombosis is not established. A case-control study was conducted of 419 hemodialysis patients to determine whether thrombophilia was associated with arteriovenous fistula or graft thrombosis. Participants were enrolled from three in-center and five satellite dialysis units associated with a Canadian academic health science center that provides dialysis services in a catchment area of one million. Patients were tested for factor V Leiden, prothrombin gene mutation, factor XIII genotype, methylenetetrahydrofolate reductase genotype, lupus anticoagulant, anticardiolipin antibody, factor VIII, homocysteine, and lipoprotein (a) concentrations. Overall, 59 (55%) patients with access thrombosis had at least one thrombophilia compared with 122 (39%) patients without access thrombosis (unadjusted odds ratio [OR], 1.91; 95% confidence interval [CI], 1.23 to 2.98). After controlling for important risk factors, the association between any thrombophilia and access thrombosis remained (adjusted OR, 2.42; 95% CI, 1.47 to 3.99). For each additional thrombophilic disorder, the odds of access thrombosis increased significantly (adjusted OR, 1.87; 95% CI, 1.34 to 2.61). This study suggests that thrombophilia is associated with access thrombosis in dialysis patients. Large, multicenter, prospective cohort studies are needed to confirm the observations from this case-control study. PMID:15728780

    Outcomes from conventional thrice-weekly hemodialysis (CHD) are disappointing for a life-saving therapy. The results of the HEMO Study show that the recommended minimum dose (Kt/V) for adequacy is also the optimum attainable with CHD. Interest is therefore turning to alternative therapies exploring the effects of increased frequency and time of hemodialysis (HD) treatment. The National Institutes of Health have sponsored 2 randomized prospective trials comparing short hours daily in-center HD and long hours slow nightly home HD with CHD. An International Registry has also been created to capture observational data on patients receiving short hours daily in-center HD, long hours slow nightly home HD, and other alternative therapies. Participation by individual centers, other registries and the major dialysis chains is growing and currently data from nearly 3000 patients have been collected. Pitfalls in data collection have been identified and are being corrected. A matched cohort (patients in other registries) study is planned to obtain information regarding hard outcomes expected from these therapies. The Registry may become the most important source of information required by governments, providers, and the nephrological community in assessing the utility of such therapies. PMID:18638245

    An arteriovenous fistula (AVF) between the radial artery and cephalic vein at the wrist is the preferred type of hemodialysis vascular access. However, in the practice of access placement, we are aware that some patients fail to form the standard forearm radial-cephalic AVF, owing to naturally small veins or acquired abnormal lesions of the veins. To identify the risk factors for failure to form the standard AVF, we examined 305 consecutive patients who underwent first-time access surgery at our hospital from January 2006 to December 2010. We compared the patients' characteristics between those having normal vessels and successfully forming the standard AVF, and those having apparently abnormal vessels and thus forming alternative types of access instead. Histories of major and minor surgery were specifically evaluated, assuming that surgical procedures in the past could potentially damage the superficial veins. We created 207 standard and 98 alternative accesses during the period and found that significantly more patients with alternative accesses (31 %) had undergone major surgery of a variety of specialties, in comparison with those with the standard AVF (15.0 %). Multivariate logistic analysis revealed that a history of major surgery (OR = 2.39, 95 %CI 1.29-4.47, p = 0.006) and female gender (OR = 1.87, 95 %CI 1.10-3.20, p = 0.02) were independent risk factors associated with failure to construct the standard AVF. Our results indicate that previous surgery can damage the superficial veins and cause venous abnormality, which makes construction of the standard AVF difficult. We propose that care should be taken to preserve the superficial veins when patients for whom dialysis therapy is a future possibility undergo surgical procedures, especially invasive ones.

    It has been reported that sevelamer hydrochloride, which is often used as a polymer phosphorus (P) binder for managing serum P concentration in dialysis patients, causes gastrointestinal adverse effects such as constipation, etc. The reason for this is thought to be that sevelamer hydrochloride has high water absorption, causing it to absorb water and swell in the gastrointestinal tract. In June 2012, the new polymer P binder bixalomer was launched in Japan. Since bixalomer has low swelling due to water absorption, it can be expected to alleviate adverse effects in the gastrointestinal system. In our study, for 21 cases of maintenance hemodialysis patients undergoing treatment with sevelamer hydrochloride at our hospital, the P binder was switched from sevelamer hydrochloride to the same dosage of bixalomer, and the concentrations of serum P, corrected calcium (Ca) and whole parathyroid hormone (PTH) before and one month after the switch were compared. In addition, gastrointestinal symptoms (acid reflux, abdominal pain, indigestion, diarrhea and constipation) were evaluated before and after the switch using a questionnaire based on the Japanese version of the Gastrointestinal Symptom Rating Scale (GSRS). By switching to bixalomer, serum P concentration was significantly reduced (P=0.024), but there were no significant changes observed for serum corrected Ca and whole PTH. Furthermore, there were no significant changes observed for all five of the evaluation items of the GSRS, before and after the switch. These results suggest that although bixalomer can more potently reduce the serum P concentration than sevelamer hydrochloride, there were no significant differences in the effects of both P binders on the gastrointestinal symptoms.

    Dialysis patients need to deal and cope with various aspects of their disease. Identifying the adaptation methods provides valuable information for planning specific treatment and medical care delivery and improving the performance of medical teams. The present study aims to evaluate the coping strategies to stress among patients undergoing hemodialysis (HD) and peritoneal dialysis (PD) at the Imam Reza Educational-Medical Hospital, Tabriz, West Azarbaijan, Iran. This descriptive and analytical study was conducted on 70 patients in the year 2012. The subjects were selected through census method and simple random sampling method. Data were collected using a customized questionnaire and consisted of demographic information and the Jalowiec Coping Scale (JCS) through a structured interview. Descriptive and inferential statistics were used to analyze the data in SPSS (version 13). The mean score of frequency of use of the coping strategy as "sometimes used" for the HD patients was 70.94 ± 18.91 and also for PD patients as "seldom used" was 58.70 ± 12.66. The mean score of helpfulness of coping strategies in the HD group was 49.57 ± 19.42 as "slightly helpful", whereas in the PD group it was 37.21 ± 14.38 as "slightly helpful" Furthermore, both groups used the emotion-oriented coping styles more frequently than the problem-oriented methods. HD patients used coping methods more frequently than the PD patients. The majority of patients used emotion-oriented coping strategies to deal with stress factors. Use of educational, counseling and supportive programs to assist in coping techniques can facilitate the coping process with stress factors in dialysis patients. PMID:25758872

    A large global dialysis provider's core activities include providing dialysis care with excellent quality, ensuring a low variability across the clinic network and ensuring strong focus on patient safety. In this article, we summarize the pertinent components of the quality assurance and safety program of the Diaverum Renal Services Group. Concerning medical performance, the key components of a successful quality program are setting treatment targets; implementing evidence-based guidelines and clinical protocols; consistently, regularly, prospectively and accurately collecting data from all clinics in the network; processing collected data to provide feedback to clinics in a timely manner, incorporating information on interclinic and intercountry variations; and revising targets, guidelines and clinical protocols based on sound scientific data. The key activities for ensuring patient safety include a standardized approach to education, i.e. a uniform education program including control of theoretical knowledge and clinical competencies; implementation of clinical policies and procedures in the organization in order to reduce variability and potential defects in clinic practice; and auditing of clinical practice on a regular basis. By applying a standardized and systematic continuous quality improvement approach throughout the entire organization, it has been possible for Diaverum to progressively improve medical performance and ensure patient safety.

    Objective: To investigate the clinical effect of percutaneous balloon angioplasty for the treatment of arteriovenous fistula stenosis or occlusion in upper extremity in hemodialysis patients. Methods: Percutaneous balloon angioplasty was performed in 14 hemodialysis patients with arteriovenous fistula stenosis or occlusion in upper extremity. The preoperative and post operative clinical manifestations, the color Doppler ultrasonographic findings, the blood flow during hemodialysis and the angiographic demonstrations were recorded and compared. Results: After balloon dilatation, the constricted segment was remarkably dilated and the occluded site was re-opened in all patients. Angiographic findings showed that the degree of stenosis was less than 30%. Conclusion: As a simple, mini-invasive and safe technique with remarkable short-term effectiveness, percutaneous balloon angioplasty is an valuable therapy for arteriovenous fistula stenosis or occlusion in upper extremity in hemodialysis patients.
