    Chronic renal failure is characterised by a gradual and sustained decline in renal clearance or glomerular filtration rate (GFR). Continued progression of renal failure will lead to renal function too low to sustain healthy life. In developed countries, such people will be offered renal replacement therapy in the form of dialysis or renal transplantation. Requirement for dialysis or transplantation is termed end-stage renal disease (ESRD).Diabetes, glomerulonephritis, hypertension, pyelone...

    Full Text Available The syndrome of chronic renal failure (CRF is already known for more than 150 years. Current research in this domain changed our understanding in epidemiology, aetiology, prevention of disease progression, classifications, definition, and adequate treatment of comorbid conditions in predialytic period. With data collection and registration on CRF patients it is obvious an increase in prevalence and incidence of patients with CRF in the world. The diabetic nephropathy is the most common disease leading in 40% of cases to terminal CRF. In the follow up of these patients the most important goal is slowing down the disease progression with low protein diet (0,6-0,8 g/kg BW/day and vigorous blood pressure control (target values: 120-135/75-85 mmHg. The adequate therapy of anaemia and secondary hyperparathyroidism including predialytic use of erythopoietin and vitamin D significantly slow down the progression of CRF and postpones the beginning of dialytic treatment. Numerous comorbid conditions present in predialytic period fasten the progression of CRF. The most common are of cardiovascular origin (congestive heart failure and coronary artery disease. Those cardiovascular comorbid conditions have an impact on CRF progresion as well as on the outcome in dialytic therapy. The most common causes of cardiovascular comorbidity are hypertension, anemia and secondary hyperparathyroidism, all of which should be treated in predialytic period. Of special concern is use of nephrotoxic drugs, particularly nephrotoxic antibioticsaminoglycosides. The optimal timing of creation of permanent vascular access and vaccination against hepatitis B in predialytic period are cost-effective and have an impact on quality of dialysis.

    Many chronic renal diseases lead to the final common state of decrease in renal size, parenchymal atrophy, sclerosis and fibrosis. The ultrasound image show a smaller kidney, thinning of the parenchyma and its hyperechogenicity (reflecting sclerosis and fibrosis). The frequency of renal cysts increases with the progression of the disease. Ultrasound generally does not allow for the exact diagnosis of an underlying chronic disease (renal biopsy is usually required), but it can help to determine an irreversible disease, assess prognosis and avoid unnecessary diagnostic or therapeutic procedures. The main exception in which the ultrasound image does not show a smaller kidney with parenchymal atrophy is diabetic nephropathy, the leading cause of chronic and end-stage renal failure in developed countries in recent years. In this case, both renal size and parenchymal thickness are preserved until end-stage renal failure. Doppler study of intrarenal vessels can provide additional information about microvascular and parenchymal lesions, which is helpful in deciding for or against therapeutic intervention and timely planning for optimal renal replacement therapy option.

    Renal fluoride toxicity in human beings is difficult to assess in the literature. Although experimental studies and research on methoxyflurane toxicity have shown frank renal damage, observations of renal insufficiency related to chronic fluoride exposure are scarce. We report a case of fluoride intoxication related to potomania of Vichy water, a highly mineralized water containing 8.5 mg/L of fluoride. Features of fluoride osteosclerosis were prominent and end-stage renal failure was present. The young age of the patient, the long duration of high fluoride intake, and the absence of other cause of renal insufficiency suggest a causal relationship between fluoride intoxication and renal failure.

    2005-01-01

    Acute and chronic renal failure secondary to bilateral severe hydroureteronephrosis is a rare sequela of uterine prolapse. We report a case of neglected complete uterine prolapse in a 72-year-old patient resulting in bilateral hydroureter, hydronephrosis, and chronic renal failure. In an attempt to diminish the ureteral obstruction a vaginal pessary was used to reduce the uterine prolapse. Finally, surgical repair of prolapse by means of a vaginal hysterectomy was performed. In conclusion, all patients presenting with complete uterine prolapse should be screened to exclude urinary tract obstruction. If present, obstructive uropathy should be relieved by the reduction or repair of the prolapse before irreversible renal damage occurs.

    Sexual dysfunction in end-stage renal disease is a troublesome, multifactorial disorder. Abnormality of the hypothalamo-pituitary-gonadal axis is but one of the causes leading to the impotence and infertility commonly encountered in chronic renal failure. Short of kidney transplantation, no therapy is available. Though infertility is the rule in end-stage renal disease, successful fatherhood and deliveries have occurred on rare occasions.

    The paper briefly summarizes issues related to urinary tract infections in adults: predispositions and risk factors, classification, assessment of pathogenicity of bacterial agents, the role of bacteriuria and leucocyturia, interpretation of findings, treatment principles and an association with chronic renal failure. Urinary tract infections are the second most frequent infectious disease in the population. They most often affect women of childbearing potential and then seniors of both sexes who have multiple risk factors. Escherichia coli and Staphylococcus saprophyticus are the most pathogenic towards urinary tract; they are responsible for 85% and 10-15% of cases of acute uncomplicated urinary infections, respectively. Chronic pyelonephritis, a chronic interstitial nephritis, is the fourth most frequent cause of chronic renal failure. Chronic renal failure is a risk factor for the development of urinary infections due to metabolic disorders resulting in secondary immunodeficiencywith a disorder of all components of immunity. In patients with chronic renal failure, urinary tract infections occur most frequently after kidney transplantation when graft pyelonephritis is a life-threatening complication. Therefore, urinary tract infection prevention with co-trimoxazole once daily over at least 6 months is recommended in renal allograft recipients.

    Full Text Available BACKGROUND The kidney and the skin are the two large networks of the body with abundant blood supply associated with various cutaneous manifestations. This study aims to detect the various cutaneous manifestations and its incidence in patients with chronic renal failure and renal transplantation. MATERIALS AND METHODS This study was done for a period of 1 year from January 2016 to December 2016 at Nephrology OPD ward and Medicine wards, Government KAPV Medical College Hospital, Trichy. During this period, 100 patients who had the presence of skin manifestations were selected and studied (80 renal failure patients and 20 renal transplantation patients. RESULTS Most of the specific cutaneous manifestations of chronic renal failure and renal transplantation were noted in this study. Pruritus and xerosis were the most common manifestations noted in chronic renal failure while infections was commonly noted in renal transplantation patients. CONCLUSION Pruritus and xerosis were the most common among the specific cutaneous manifestations in chronic renal failure followed by nail abnormalities and pigmentary changes. Cutaneous manifestations of renal transplantation were mostly due to infections of which fungal infection is the most common followed by viral infection.

    The causes of malnutrition in chronic terminal kidney failure are reviewed in the situation both before and after dialysis, as are the malnutrition rates in both circumstances and their treatment. Malnutrition has a high prevalence in terminal kidney patients, partly as a result of the therapeutic restriction on calories and proteins, but also due to the metabolic reactions typical of the disease and to anorexia. In patients subjected to dialytical methods, certain other mechanisms are added. In addition to malnutrition, there are alterations in the metabolism of calcium, phosphorus and potassium, as well as lipids, thus limiting nutritional therapy's ability to restore the nutritional status to normal. An awareness of energy expenditure in chronic terminal kidney failure and the consequences of malnutrition have led to new challenges in nutritional therapy, both in the dose and quality of the proteins, with a debate raging over the advantages of ketoanalogues, and also in the methods for providing nutrients. The ideal nutritional method for repletion is oral administration, but this can be enhanced with artificial support such as oral supplements, parenteral nutrition during dialysis or such alternatives as enteral nutrition at home in the case of chronic kidney problems in children, using percutaneous endoscopic gastrostomy (PEG), in order to nourish the patients and minimize growth disorders.

    Increased incidence of cancer at various sites is observed in patients with end-stage renal disease (ESRD). Certain malignant diseases, such as lymphomas and carcinomas of the kidney, prostate, liver and uterus, show an enhanced prevalence compared with the general population. In particular, renal cell carcinoma (RCC) shows an excess incidence in ESRD patients. A multitude of factors, directly or indirectly associated with the renal disease and the treatment regimens, may contribute to the increased tumor formation in these patients. Patients undergoing renal replacement therapy (RRT) are prone to develop acquired cystic kidney disease (ACKD), which may subsequently lead to the development of RCC. In pre-dialysis patients with coexistent renal disease, as in dialysis and transplant patients, the presence of ACKD may predispose to RCC. Previous use of cytotoxic drugs (eg, cyclophosphamide) or a history of analgesic abuse, are additional risk factors for malignancy. Malignancy following renal transplantation is an important medical problem during the follow-up. The most common malignancies are lymphoproliferative disorders (early after transplantation) and skin carcinomas (late after transplantation). Another important confounder for risk of malignancy after renal transplantation is the type of immunosuppression. The type of malignancy is different in various countries and dependent on genetic and environmental factors. Finally, previous cancer treatment in a uremic patient on the transplant waiting list is of great importance in relation to waiting time and post-malignancy screening.

    Full Text Available Protein energy wasting is frequently observed in patients with advanced chronic renal failure and end-stage renal disease. Anorexia and reduced food intake are critical contributing factors and negatively impact on patients' survival. Ghrelin is a prophagic peptide produced by the stomach and acting at the hypothalamic level to increase the activity of orexigenic neurons. In patients with chronic renal disease, plasma levels are increased as a likely effect of reduced renal clearance. Nevertheless, patients' food intake is significantly reduced, suggesting inflammation-mediated resistance of hypothalamic nuclei to peripheral signals. A number of forms of evidence show that ghrelin resistance could be overcome by the administration of exogenous ghrelin. Therefore, ghrelin has been proposed as a potential strategy to improve food intake in chronic renal failure patients with protein energy wasting. Preliminary data are encouraging although larger prospective clinical trials are needed to confirm the results and to identify those patients who are likely to benefit most from the administration of exogenous ghrelin.

    Full Text Available Gastrointestinal (GI hemorrhage is a frequent and sometimes life-threatening complication of end-stage renal failure. Angiodysplasia (AD, vascular malformation, is the most common cause of recurrent lower-intestinal hemorrhage in patients with renal failure. We report four chronic hemodialysis patients with AD. All patients presented with severe anemia requiring transfusion. GI hemorrhage ceased spontaneously in three cases and after treatment with argon plasma coagulation in another. Diagnosis of AD is usually challenging, since its cause is still unknown, and its clinical presentation is variable. Lesions are multiple in 40-75% of cases, often located in the stomach and duodenum but can affect the colon and the jejunum. Diagnosis is improved by endoscopy which has a much higher sensitivity compared to angiography. Capsular endoscopy may reveal the hemorrhage site in the small intestine when regular endoscopy fails, and therapeutic intervention usually include argon plasma coagulation.

    In chronic renal failure (CRF), renal impairment correlates with tubulointerstitial fibrosis characterized by inflammation, interstitial expansion with accumulation of extracellular matrix (ECM), tubular atrophy and vascular obliteration. Tubulointerstitial injury subsequent to glomerular sclerosis may be induced by proteinuria, leakage of glomerular filtrate or injury to the post-glomerular peritubular capillaries (hypoxia). In vivo data in animal models suggest that CRF is associated with hypoxia, with the decline in renal Po2 preceding ECM accumulation. Chronic renal failure is characterized by loss of microvascular profiles but, in the absence of microvascular obliteration, hypoxia can occur by a variety of complementary mechanisms, including anaemia, decreased capillary flow, increased vasoconstriction, increased metabolic demand and increased diffusion distances due to ECM deposition. Hypoxia regulates a wide array of genes, including many fibrogenic factors. Hypoxia-inducible factors (HIF) are the major, but not the sole, transcriptional regulators in the hypoxic response. In CRF, hypoxia may play a role in the sustained inflammatory response. In vitro studies in tubulointerstitial cells suggest that hypoxia can induce profibrogenic changes in proximal tubular epithelial cells and interstitial fibroblasts consistent with changes observed in CRF in vivo. The effect of hypoxia on renal microvascular cells warrants investigation. Hypoxia may play a role in the recruitment, retention and differentiation of circulating progenitor cells to the kidney contributing to the disease process and may also affect intrinsic stem cell populations. Chronic hypoxia in CRF fails to induce a sustained angiogenic response. Therapeutic manipulation of the hypoxic response may be of benefit in slowing progression of CRF. Potential therapies include correction of anaemia, inhibition of the renin-angiotensin system, administration of exogenous pro-angiogenic factors to protect the

MATERIALS AND METHODS Two hundred and thirty eight cases were enrolled in the study from the nephrology unit of College Of Medical Science, Bharatpur, Nepal and examined in the department of Ophthalmology. The study duration was carried out over 2 years from January 2011 to December 2012. RESULT The number of cases in each grade of CRF were mild 80 (26.67%, moderate 84 (28%, severe 75 (25%, end stage renal disease 61 (20.33%. In all the groups the commonest cause of CRF were Hypertension (HTN 123 out of 300(41% and diabetes 98(32.67%. The commonest ocular symptoms in CRF was blurring of vision 68%. CONCLUSION Many important ocular findings like vitreous haemorrage, retinal detachment, neovascular glaucoma and cataract are the presentation in chronic renal failure, which can cause marked vision loss. Hence proper awareness should be provided to the people in time to prevent these ocular complications.DOI: http://dx.doi.org/10.3126/jcmsn.v10i2.12949 Journal of College of Medical Sciences-Nepal, 2014, Vol.10(2; 18-26

    Full Text Available HBV infection in chronic renal failure (CRF becomes chronic in 30 to 60% compared with less than 10% in nonuremic patients. Immunological dysfunction in patients on hemodialysis may be related to imbalanced cytokine systems, such as tumor necrosis factor (TNF-|α| and interleukin (IL 6,1 by retention of renal metabolite in uremia and chronic inflammation and have a poor immunological reaction to T-cell-dependent antigens, like hepatitis B vaccination. Immunocompromised patients who are unresponsive to hepatitis B vaccination seem to be unable to enhance IL-10 synthesis for control of monokine overproduction. Moreover, human leukocyte antigen (HLA genes, which play a major role in the antigen presentation to immunocompetent cells, have also been shown to modulate this immune response. Unfortunately, seroconversion to anti-HBS has been reported to occur in only 40 to 50% of the vaccine, a significantly lower rate than that observed in healthy adults. Various methods including adjutants such as zinc, gamma interferon, thymopentine, GM-CSF and Levamisol for improving immune responses have been advised. Experience with Pres1/s2, third-generation vaccines is limited and they have not been proven more effective than intradermally (ID administered second-generation S antigen vaccines. Both intramuscular (IM and intradermal (ID vaccinations against hepatitis B have variable efficiency in hemodialysis and non-responders should be retreated by ID route.

  3. Gastrointestinal function in chronic renal failure.

    Feeding problems, anorexia and vomiting are common in infants and children with chronic renal failure (CRF), and play a major role in the growth failure often found in this condition. However, the gastroenterological and nutritional aspects of CRF in children have received little attention, hence therapeutic interventions are usually empirical and often ineffective. Gastritis, duodenitis and peptic ulcer are often found in adults with CRF on regular haemodialysis and following renal transplantation. Despite persistent hypergastrinaemia, gastric acid secretion is decreased rather than increased in most of these patients, and active peptic disease appears to be promoted by the removal of the acid output inhibition (neutralisation of gastric acid by ammonia) that follows active treatment. Helicobacter pylori, on the other hand, does not seem to play a significant role in the pathogenesis of peptic disease in CRF. Gastro-oesophageal reflux has been found in about 70% of infants and children with CRF suffering from vomiting and feeding problems, and thus appears to be a major problem in these patients. In a number of symptomatic patients with CRF, gastric dysrhythmias and delayed gastric emptying have also been found; hence there appears to be a complex disorder of gastrointestinal motility in CRF. Serum levels of several polypeptide hormones involved in the modulation of gastrointestinal motility [e.g. gastrin, cholecystokinin (CCK), neurotensin] and the regulation of hunger and satiety (e.g. glucagon, CCK) are significantly raised as a consequence of renal insufficiency, and can be reverted to normal by renal transplantation. Furthermore, several other humoral abnormalities (e.g. hypercalcaemia, hypokalaemia, acidosis, etc.) are not uncommon in CRF. By directly affecting the smooth muscle of the gut or stimulating particular areas within the central nervous system, all these humoral alterations may well play a major role in the gastrointestinal dysmotility, anorexia

    Pregnancy in women with chronic renal failure is a complex therapeutic problem requiring a multidisciplinary approach. It is associated with a higher risk of many perinatal complications. The most common abnormalities are related to: progression of renal failure, development of preeclampsia development of nephrotic syndrome, anemic syndrome, IUGR and fetal death. The prognosis depends on the values of serum creatinine prior to pregnancy, the degree of deterioration of renal function, development of additional obstetric complications and the specific etiological reasons that have led to the occurrence of renal failure. Determining the optimum time for authorization birth depends on the condition of the mother, the condition of the fetus and the rate of progression of renal failure, and the deadline the pregnancy should be terminated is 35 weeks. We present a case of a patient with chronic renal failure, with favorable perinatal outcome.

    Background Acute renal failure describes as a syndrome by rapid decline in the ability of the kidney to eliminate waste products, regulate acid–base balance, and manage water homeostasis. When this impairment is prolonged and entered chronic phase, erythropoietin secretion by this organ is decreasing and toxic metabolic accumulates and causes hematological changes include decrease of HCT, MCV and RBC and platelet counts. This study evaluates present of anemia and thrombocytopenia in patients with acute and chronic renal failure. Materials and Methods This study conducted on 132 patients with renal impairment and also 179 healthy individuals as two separated control groups. Initially patients with renal problem were tested and after confirmation of impairment, patients were divided in two groups, acute with less than 3 months and chronic with more than 3 months renal failure, based on duration of the disease. Then complete blood count performed for each patient and finally obtained data were analyzed by SPSS software. Results Comparison between 96 patients with acute and 36 patients with chronic renal failure revealed that severity of anemia (HCT, Hb and MCV) between these two groups were statistically high in comparison with control groups (P > 0.05) but thrombocytopenia in patients with chronic renal failure was statistically different from control and the acute ones (P < 0.001). Conclusion It was recommended that in patients with chronic renal failure, to prevent the risk of bleeding, platelet count should be checked periodically. PMID:24505541

    The aim of this work was to review evidence on the role of the sympathetic nervous system (SNS) in chronic renal failure (CRF). Three main points are discussed: 1) SNS and pathogenesis of arterial hypertension; 2) SNS and cardiovascular risk; 3) implication of SNS in arterial hypotension during hemodialysis. Several lines of evidence indicate the presence of a sympathetic hyperactivity in CRF, and its relationship with arterial hypertension. It is suggested that diseased kidneys send afferent nervous signals to central integrative sympathetic nuclei, thus contributing to the development and maintenance of arterial hypertension. The elimination of these impulses with nephrectomy could explain the concomitant reduction of blood pressure. Several experiments confirmed this hypothesis. Regarding SNS and cardiovascular risk, some data suggest that reduced heart rate variability identifies an increased risk for both all causes and sudden death, independently from other recognized risk factors. Symptomatic hypotension is a common problem during hemodialysis treatment, occurring in approximately 20-30% of all hemodialysis sessions and is accompanied by acute withdrawal of sympathetic activity, vasodilation and relative bradicardia. This reflex is thought to be evoked by vigorous contraction of a progressively empty left ventricle, activating cardiac mechanoceptors. This inhibits cardiovascular centers through vagal afferents, and overrides the stimulation by baroreceptor deactivation. Alternative explanations include cerebral ischemia and increased production of nitric oxide, which inhibit central sympathetic activity. It is hoped that therapies aimed at modulating sympathetic nerve activity in patients with CRF will ameliorate their prognosis and quality of life.

MATERIAL and METHODS: Using data collected with a structured questionnaire and considering physicians’ socio-demographic features and their education on nephrology, we evaluated physicians’ awareness of the definition, frequency and clinical features of chronic renal failure. The questionnaire was filled in by volunteering family medicine specialists (FMS, family medicine assistants (FMA and family physicians (FP during a family medicine meeting. RESULTS: Out of 310 physicians, 25.2% (n=78 were FMS, 27.7% (n=86 FMA and 47.1% (n=146 FP. %35,2 of physicians (n=109 (FMS: % 62,8 (n=49, FMA: %52.3 (n=45, FP: %10.3 (n=15, p0.05. However, less than 15% of the physicians reported that they felt competent enough to follow patients with chronic renal failure. The rate of the physicians who felt the need to refer these patients to health institutions was high. However, the Fps did not like the patient care style of internal medicine specialists and thought that patients faced financial problems to access the nephrologist. CONCLUSION: Appropriate care and management of referrals are life-saving for patients with chronic renal failure. New strategies should be developed to increase awareness concerning chronic renal failure and the management of this condition.

    The realisation that circulating gastrin is heterogeneous necessitates a reappraisal of gastrin's role in the increased incidence of duodenal ulcer disease that occurs in chronic renal failure. Radioimmunoassays employing region-specific antisera have been used to examine renal and extrarenal factors controlling serum gastrin concentration in patients with chronic renal failure. The present study has shown that basal serum gastrin concentrations measured with a carboxyl-terminal specific antibody were significantly higher in eight patients with chronic renal failure treated by dietary restriction (388+/-196 pM) than in 14 patients with chronic renal failure treated by haemodialysis (28.7+/-4.6 pM). However, basal gastrin concentrations in both groups of patients were significantly higher than in 25 normal subjects (12.3+/-1.8 pM) and showed significant negative correlations with maximal gastric acid secretion (p renal failure patients who were also achlorhydric. Although the peak postprandial increment in big gastrin concentration in 11 chronic renal failure patients (34.0+/-7.5 pM) was significantly greater (p exogenous little gastrin was similar in four chronic failure patients (clearance half time: 8.1+/-0.7 min) and four normal subjects (clearance half time: 6.5+/-1.2 min). These studies suggest that the human kidney is unimportant in the metabolism of little gastrin. As circulating little gastrin is six times more potent than big gastrin in stimulating acid secretion, these studies suggest that the raised gastrin concentrations observed in patients with chronic renal failure have little significance in terms of their increased incidence of duodenal ulcer disease.

    2011-02-01

    Chronic renal failure patients receiving hemodialysis and continuous ambulatory peritoneal dialysis often encounter gastrointestinal troubles over their long treatment period. Helicobacter pylori infection has close association with development of peptic ulcer, gastric cancer and gastric lymphoma, and is thought to be one of the major risk factors for gastrointestinal troubles in dialysis patients. However, it is unclear whether H. pylori infection is directly associated with progression of renal dysfunction and prognosis of chronic renal failure patients. Recent consensus shows that the prevalence of H. pylori infection in chronic renal failure patients is significantly lower than in subjects with normal renal function. In the natural history of H. pylori infection in hemodialysis patients, the prevalence of infection decreases as dialysis periods progressed, in particular within the first four years after the start of treatment. However, the chance of natural eradication becomes rare for patients receiving dialysis treatment for a long time. Moreover, chronic renal failure patients with H. pylori infection have a higher incidence of gastroduodenal diseases, and therefore, are recommended to receive eradication therapies, especially for those receiving treatment for a long time and with higher risks of complication. Intensive endoscopic check-ups for the prevention of gastrointestinal events and the discovery of peptic ulcer and neoplastic diseases at an early phase may be required.

    The incidence of chronic renal failure in the elderly is rising due to the ageing of the general population. Its management, and notably nephroprotective therapies, must be adapted to the elderly person who is often frail and with multiple pathologies. The decision to start extra-renal purification does not depend on the patient's chronological age but on their physiological age and requires dialogue between the patient and their family, the geriatrician and the nephrologist.

    In patients with chronic renal failure on regular dialysis treatment, limboconjunctival degenerations and calcifications are commonly observed. In this study three groups of patients were followed over a period of 6 years. The first group consisted of 47 patients with renal failure, the second group of 17 patients with renal failure and hyperparathyroidism not controlled by drugs, and the third group seven patients with primary hyperparathyroidism without renal failure. The aim of this study was to determine the progression of the limboconjunctival changes over time. The hypothesis that an increase in serum calcium and phosphorus concentrations, as a result of tertiary hyperparathyroidism, could possibly add a corneal component to the limbal calcification was also tested. All patients with renal failure (in as much as the degenerative limbal features were not obscured by deposits of lime salts), had a type II white limbus girdle of Vogt. This limbal degeneration was observed in only 45% of controls. In all 47 patients with renal failure conjunctival calcification was observed; 26 of them also had limbal calcification. After 6 years 41 patients had developed limbal calcification. This progression was statistically significant. In 15 out of 17 patients with tertiary hyperparathyroidism a band-shaped keratopathy developed in addition to the limboconjunctival calcification.

    Full Text Available Rocuronium is a non-depolarizing aminosteroidal neuromuscular blocking agent that is widely used in general anesthesia. Its effects may be prolonged in patients with renal disease, especially renal failure, due to reduced clearance of the drug. Sugammadex, a modified γ-cyclodextrin, is known to be a highly effective reversal agent for rocuronium-induced muscle relaxation. However, the administration of sugammadex for reversal of rocuronium-induced neuromuscular block in patients with renal disease is controversial. Recently, we administered rocuronium for neuromuscular blockade during the surgery of two patients with chronic renal failure, instead of cisatracurium, a benzylisoquinoline compound. Therefore, we had to administer sugammadex to ensure maximum alleviation of residual neuromuscular blockade risk after surgery. Although the effect of rocuronium was prolonged during surgery, sugammadex quickly and completely restored the response of train-of-four stimulation postoperatively. There were no residual neuromuscular block signs or symptoms observed in these patients throughout the postoperative period. In this report, we share our experience with these cases, and discuss the effectiveness and safety of sugammadex in the context of chronic renal failure.   Keywords: Neuromuscular blockade; Neuromuscular monitoring; Renal failure; Residual neuromuscular blockade; Rocuronium; Sugammadex

    The pharmacokinetics of a single oral dose of roxatidine acetate 150 mg were studied in 31 patients with varying degrees of chronic renal failure. The patients were divided into 5 groups according to their creatinine clearance (Clcr): controls (Clcr 94.5 +/- 13.9 ml/min; n = 6); mild chronic renal failure (Clcr 47 +/- 6 ml/min; n = 4); moderate chronic renal failure (Clcr 27.3 +/- 3.1 ml/min; n = 4); severe chronic renal failure (Clcr 12.8 +/- 1.4 ml/min; n = 5) and uraemia (Clcr 6.6 +/- 0.6 ml/min; n = 12). Serum and urine samples were analysed with capillary gas chromatography to measure the salt of the desacetyl metabolite of roxatidine acetate (roxatidine). The terminal half-life was 6.02 +/- 0.31 hours in controls and 7.35 +/- 0.57, 9.3 +/- 0.83, 14.6 +/- 3.7 and 18.10 +/- 2.77 hours, respectively, in the 4 other groups, with progressively decreasing creatinine clearance. Maximum serum concentration and time to maximum serum concentration rose from 816 +/- 75 ng/ml and 2.08 +/- 0.22 hours, respectively, in controls to 1364.7 +/- 156 ng/ml and 4.05 +/- 0.47 hours, respectively, in uraemic patients. Relative total clearance progressively decreased with decreasing glomerular filtration rate (GFR) [from 353.6 +/- 26 ml/min in controls to 90.31 +/- 12.2 ml/min in patients with uraemia]. Renal clearance decreased from a control of 243.9 +/- 56 ml/min to 12.32 +/- 0.18 ml/min in uraemic patients. A linear correlation between creatinine clearance and both relative total clearance and renal drug clearance was noted.(ABSTRACT TRUNCATED AT 250 WORDS)

    We analyzed 19 patients with focal segmental glomerulosclerosis (FSGS): 11 males and 8 females (mean age 38.3 yrs. (SD 16.4), who were under observation for 39.4 months (SD 17.2). At the moment of renal biopsy 73.7% of patients had arterial hypertension, 52.6%--nephrotic proteinuria, 36.9%--chronic renal failure. Global glomerulosclerosis was present in 14 biopsies (73.7%), and intersticial fibrosis--in 13 biopsies (68.4%). The results of analysis showed multiple risk factors for progression of renal failure: initial renal failure (p=0.005), proteinuria (> or =3 g/l) (p=0.005), expressed glomerulosclerosis (p=0.005) and expressed interstitial fibrosis (p=0.034). Focal segmental glomerulosclerosis were found to have a relatively bad long-term prognosis--the renal survival rate in 5 years was 77.8%. Kaplan-Meier survival analysis showed that expressed glomerulosclerosis was risk factor (logrank p=0.016, Breslov p=0.043) associated with end-stage renal disease in 5 years.

In the current study urinary peptide levels were determined in chronic renal failure (CRF patients. Method: 86 CRF patients and 80 healthy controls were selected for the study. Urinary proteins and peptide levels were determined by spectrophotometer based Lowry and Bradford methods. Urinary creatinine levels were determined by clinical chemistry analyzer. Results: There was significant decrease in urinary peptide levels in CRF patients and Urinary % peptides were significantly decreased in CRF patients as compared to healthy controls. Urinary % peptides correlated negatively with proteinuria. Conclusion: we have found decrease in urinary peptides and % urinary peptides in CRF patients and possibly measurement of % urinary peptides may possibly serve as better indicator in early detection of impairment in renal function.

    The purpose of the study was to investigate the coping behaviours of Chinese patients with chronic renal failure. The study, based on Lazarus and Folkman (Stress, Appraisal and Coping, Springer, New York, 1984) model of coping, was conducted to identify the process by which 11 chronic renal failure patients cope with their disease. The identified themes are coping with fluctuating feelings and concerns, motivation to cope, interdependent relationships between patients and their family members and modes of coping strategies. The significance of the results indicates that coping is the consequence not only of situational demands but also of life goals. Meaning in life is an important motivator in the coping process. Besides problem-focused coping and emotion-focused coping, another important element is relationship-focused coping. The interdependent influences of families on patients and patients on families are also important factors. The role of family and cultural factors is discussed as it affects how patients with chronic renal failure cope with their illness.

    Full Text Available Nine cases of tuberculosis (TB were diagnosed among 800 uremic patients, followed-up during 11 years, a prevalence of 1125%, 2.5 times higher than that in the general population. Six patients (66.7% had lymph node involvement (4 cervical and 2 mediastinal. Three patients (33.3% had pulmonary involvement (2 pleuro-pulmonary and 1 bilateral apical pulmonary. Eight patients were undergoing dialysis and 1 was pre-dialytic. The duration of dialysis ranged from 1 to 60 months. Three patients had previously received immunosuppressive drugs for unsuccessful renal transplantation. Daily fever was present in all but one patient; he was asymptomatic and TB was suspected after routine chest radiography. Biopsy was the diagnostic procedure in 7 patients (77.8%, four by direct cervical lymph node biopsy, 2 by mediastinal, performed by mediastinoscopy and 1 by pleural biopsy. In 2 other patients TB was confirmed by the presence of tubercle bacilli; in sputum (1 patient and in a bronchial flushing specimen (the other patient. Triple therapy was used in all patients (isoniazid and ethambutol in all, plus rifampicin in 8 and streptomycin in 1. One patient had jaundice and another had optical neuritis. Five patients were cured. The other four died during treatment of causes unrelated to TB or its treatment.

    Chronic kidney disease (CKD) is a worldwide public health problem. Cardiovascular disease (CVD) is frequently associated with CKD, which is important because individuals with CKD are more likely to die from CVD than to develop kidney failure. CVD in CKD is treatable and potentially preventable and CKD appears to be a risk factor for CVD. In order of incidence and frequency systemic hypertension, left ventricular failure, congestive cardiac failure, ischemic heart disease, anaemic heart failure, rhythm disturbances, pericarditis with or without effusion, cardiac tamponade, uraemic cardiomyopathy are various cardiovascular complications encountered in patients with chronic renal failure. A patient may present with one or more complications of cardiovascular system. The survival rate and prognosis to a great extent depends on proper management of these complications. Use of regular dialysis and renal transplant has changed the death pattern in developed countries but it is still a major problem in developing country. The aim of this article is early detection of CKD and proper management of it thereby preventing the major cardiovascular complications.

    We present the case of a young adult patient with chronic renal failure who developed painful subcutaneous nodules after failed renal transplant and recommencing dialysis. These nodules were juxta-articular in location and initially located over both shoulders. Radiological evaluation suggested tumoral calcinosis. The patient was placed on a strict dialysis and dietary regimen but was suboptimally compliant with same. The patient developed progressive disease with an increase in size and number of juxta-articular calcified soft-tissue masses. However, 6 months following a second renal transplant clinical and radiological follow up demonstrated marked resolution both in symptomatology and radiographic findings. We present the plain radiographic, CT and MRI findings which demonstrate the typical radiological features of tumoral calcinosis. We correlate these findings with clinical course and histological findings following surgical excision of one of these masses.

    Renal dysfunction (RD) is associated with increased mortality in heart failure (HF). The aim of this study was to identify whether worsened or improved renal function during mid-term follow-up is associated with worsened outcomes in patients with chronic HF. A total of 892 participants from a multicenter cohort study of chronic HF were followed over 3.1 ± 1.9 years of enrollment. Worsened and improved renal functions were tested with multivariate models as independent predictors of HF hospitalization and mortality. Although 12% of subjects experienced a ≥25% decrease in estimated glomerular filtration rate (eGFR), 17% experienced a ≥25% increase in eGFR, and there was stability of kidney function observed in the cohort as a whole. The quartile with the worst RD at any point in time had increased risk of HF hospitalization and mortality. Worsened eGFR was associated with HF outcomes in the unadjusted (hazard ratio = 1.71, 95% confidence interval 1.04 to 2.81, p = 0.035), but not the adjusted analysis. Improvement in eGFR was not associated with outcome (p = 0.453). In chronic HF, the severity of RD predicts risk of poor outcome better than changes in renal function during mid-term follow-up. This suggests that in patients with appropriately treated chronic HF, worsening renal function in itself does not yield useful prognostic information and may not reflect poor outcome.

    Plasma renin activity, plasma aldosterone levels and renal tubular capacity to excrete hydrogen ions were studied in 13 patients suffering from diabetes mellitus with a creatinine clearance of less than 40 ml/min. The results were compared with those obtained in a control group, in a group of nondiabetic subjects with chronic renal failure (CRF) and in a group of diabetic patients without CRF. Twelve of the thirteen diabetic patients with CRF had data characteristic of hyporeninemic hypoaldosteronism associated with type IV renal tubular acidosis. On comparing the results with those of the other two groups of patients, it was observed that the manifestations of the latter two groups considered separately were different from those of the problem group, although in the diabetic patients with normal glomerular filtration rate (GFR) hyporeninism but not hypoaldosteronism was present accompanied by a lower net acid excretion (p less than 0.001) due to a lower excretion of NH4 (p less than 0.05) and titratable acid (p less than 0.001) when the patients were challenged with an NH4Cl overload. We believe that a conjunction of diabetes and renal failure is necessary for the diabetic patients with a decrease in GFR to show hyporeninemic hypoaldosteronism and type IV tubular acidosis.

    Perforating dermatoses are a group of skin diseases characterized by transepidermal elimination of dermal material. The disease is divided into two groups: the primary group and the secondary group. The classical or primary perforating dermatoses are subdivided into four types according to the eliminated dermal materials: Kyrle disease, perforating reactive collagenosis, elastosis perforans serpiginosa, and perforating folliculitis. The secondary form is known as acquired perforating dermatosis. The term was proposed in 1989 by Rapini to designate the perforating dermatoses affecting adult patients with systemic disease, regardless of the dermal materials eliminated. This report describes a case of the disease with elimination of collagen and elastic fibers in a patient with chronic renal failure.

    The possible beneficial effect of regular exercise training on the progression of chronic renal failure was studied in a prospective randomized controlled study. Thirty patients with a median glomerular filtration rate (GFR) of 25 ml/(min.1.73 m2) (range 10-43) were randomized to physical training...... the rate of progression judged by the slope of GFR versus time plot was equal in the two groups. Hence, the beneficial effect of exercise training, earlier observed in rat studies, could not be reproduced in our patients. Physical exercise had no untoward effect on progression of renal disease....... (30 min of bicycling daily or an equal amount of other physical activities) or to maintenance of the usual lifestyle. The median maximal work capacity increased significantly in the exercise group and remained unchanged in the control group during a median observation time of 20 months whereas...

    Full Text Available Introduction. Hemodialysis and transplantation are performed not only to replace renal function, but also to improve patients' quality of life. The aim of our investigation was to compare the quality of life in patients with chronic renal failure (CRF before and after the introduction of active therapy. Material and methods. We tested 76 patients (pts: 20 pts on conservative therapy (CT, 21 pts on chronic hemodialysis and 35 pts with renal transplantation. A questionnaire (combining two questionnaires was used to investigate the physical, emotional and social aspects of health. Results. In regard to physical health of transplantation patients (TP it was established that work capacity and activities were less damaged, whereas physical activity was highest in pts on CT. Social activity was limited in a higher percentage in TP (40% than in hemodialysis patients (HD (19%, while family relationships were most damaged in pts on HD (28.57%. Discomforts were most common in pts on HD. The highest percentage of pts estimated their health status as good or average, but their health status improved after transplantation in 82.86% that is in 57.14% after HD. It was similar with the quality of life: 28.57% of kidney transplant patients rated their quality of life as very good, and 54.28% rated it as good; 38.09% of HD patients rated their quality of life as very good, whereas only 5% of CT patients rated it as very good, and 20% as good. .

    Full Text Available Chronic renal failure (CRF is one of the best known renal diseases. It is characterized by a deterioration in the overall renal function and is associated with other conditions such as hypertension, diabetes mellitus, uropathy, chronic glomerulonephritis and autoimmune diseases. Patients with CRF show alterations of the masticatory system that are specific to the disease and other type of disorders as a result of treatment. Oral health in dialysis and transplant patients tends to be poor, which makes them more likely to develop pathological conditions in the oral cavity, potentially increasing morbidity, mortality and affecting the quality of life of patients. Among the lesions we can find dysgeusia, periodontitis, candidiasis, gingival bleeding, petechiae, and joint alterations. Gingivitis and xerostomia associated to long-term use medications can cause oral lesions. Children with CRF show two oral conditions of interest: high incidence of dental anomalies and low caries activity. In patients receiving a kidney transplant, previous dental treatment is critical because the immune status of the patient will be affected not only by the toxemia, but by the immunosuppressive drugs used to prevent transplant rejection. Therefore, the dentist plays an important role in training parents and/or guardians, doctors and paramedics on the treatment of oral lesions in these patients

    Full Text Available Management of patients with renal failure remains a major problem in poor-resource nations. Cutaneous manifestations in this group of patients are varied and remain helpful in differentiating acute from chronic renal failure (CRF. We studied the prevalence and pattern of skin disorders in patients with CRF at The University College Hospital, Ibadan, Nigeria, during the period between May 2006 and February 2007. Relevant information was collected with the aid of a questionnaire. The patients were then examined for skin disorders. One hundred and twenty patients who met the inclusion criteria were recruited into the study. The mean age of the CRF patients was 43.12 ± 15.38 years, while that of the control subjects was 43.13 ± 15.38 years. Seventy-six of the 120 patients (63.3% were on chronic hemodialysis while 44 (36.5% were on conservative management. A total of 107 patients (89.1% had at least one skin problem. The skin disorders seen include xerosis in 72 (60%, pruritus in 32 (26.7%, hyper-pigmentation, icthyosis and pityriasis versicolor in nine patients each (7.5%, either singly or in combination. Pallor of the skin was seen in three of the patients (2.5%, while uremic frost was seen in one (0.8%. Nail changes were seen in 48 patients (40%. We conclude that xerosis, pruritus, pigmentary and nail changes were the most common skin disorders in patients with CRF in our environment.

    Full Text Available Cardiovascular disease is highly prevalent in patients with chronic renal failure (CRF. However, data on the impact of CRF on the cerebral circulatory system are scarce—despite the fact that stroke is the third most common cause of cardiovascular death in people with CRF. In the present study, we examined the impact of CRF on behavior (anxiety, recognition and ischemic stroke severity in a well-defined murine model of CRF. We did not observe any significant increases between CRF mice and non-CRF mice in terms of anxiety. In contrast, CRF mice showed lower levels of anxiety in some tests. Recognition was not impaired (vs. controls after 6 weeks of CRF but was impaired after 10 weeks of CRF. Chronic renal failure enhances the severity of ischemic stroke, as evaluated by the infarct volume size in CRF mice after 34 weeks of CRF. Furthermore, neurological test results in non-CRF mice tended to improve in the days following ischemic stroke, whereas the results in CRF mice tended to worsen. In conclusion, we showed that a murine model of CRF is suitable for evaluating uremic toxicity and the associated neurological disorders. Our data confirm the role of uremic toxicity in the genesis of neurological abnormalities (other than anxiety.

    Full Text Available Introduction. Properly preserved renal perfusion is the basic determinant of oxygenation, vitality, nutrition, and organ function and its structure. Perfusion disorders are functional changes and are ahead of the appearance of biochemical markers of organ damage. The aim of this study was to evaluate a relationship between the renal cortex perfusion and markers of cardiovascular organ damage in patients with stable chronic renal failure (CKD. Methods. Seventeen patients (2 F; 15 M; age 47±16 with stable CKD at 2–4 stages and hypertension or signs of heart failure were enrolled in this study. Blood tests with an estimation of renal and cardiac functions, echocardiographic parameters, intima-media thickness (IMT, renal resistance index (RRI, and total (TPI, proximal (PPI, and distal (DPI renal cortical perfusion intensity measurements were collected. Results. DPI was significantly lower than PPI. TPI significantly correlated with age, Cys, CKD-EPI (cystatin, and IMT, whereas DPI significantly depended on Cystain, CKD-EPI (cystatin; cystatin-creatinine, IMT, NT-proBNP, and troponin I. In multiple stepwise regression analysis model only CKD-EPI (cystatin independently influenced DPI. Conclusions. Cardiovascular and kidney damage significantly influences renal cortical perfusion. Ultrasound measurement of renal perfusion could be a sensitive method for early investigation of cardiovascular and renal injuries.

    The activation of the sympathetic nervous system is associated with cardiovascular hospitalizations and death in heart failure. Renal denervation has been shown to effectively reduce sympathetic overdrive in certain patients with uncontrolled hypertension. Pilot trials investigating renal denervation as a potential treatment approach for heart failure were initiated. Heart failure comorbidities like obstructive sleep apnea, metabolic syndrome and arrhythmias could also be targets for renal denervation, because these occurrences are also mediated by the activation of the sympathetic nervous system. Therefore, renal denervation in heart failure is worthy of further investigation, although its effectiveness still has to be proven. Herein, we describe the pathophysiological rationale and the effect of renal denervation on surrogates of the heart failure syndrome.

    Patients with chronic renal failure are characterized by a tonic elevation of sympathetic tone. This factor largely contributes to their increased cardiovascular risk. The increased sympathetic drive is caused by activiation of renal afferent fibers in the diseased kidneys. Therapeutic options for hypertensive patients with chronic renal failure with respect to their sympathetic overactivity are inhibitors of the renin-angiotensin-system and central sympatholytic drugs. The role of catheter-based renal denervation in these patients is currently under investigation.

    The association between cardiac failure and renal function impairment has gained wide recognition over the last decade. Both structural damage in the form of systemic atherosclerosis and (patho) physiological hemodynamic changes may explain this association. As regards hemodynamic factors, renal impairment in chronic heart failure is traditionally assumed to be mainly due to a decrease in cardiac output and a subsequent decrease in renal perfusion. This will lead to a decrease in glomerular filtration rate and a compensatory increase in tubular sodium retention. The latter is a physiological renal response aimed at retaining fluids in order to increase cardiac filling pressure and thus renal perfusion. In heart failure, however, larger increases in cardiac filling pressure are needed to restore renal perfusion and thus more volume retention. In this concept, in chronic heart failure, an equilibrium exists where a certain degree of congestion is the price to be paid to maintain adequate renal perfusion and function. Recently, this hypothesis was challenged by new studies, wherein it was found that the association between right-sided cardiac filling pressures and renal function is bimodal, with worse renal function at the highest filling pressures, reflecting a severely congested state. Renal hemodynamic studies suggest that congestion negatively affects renal function in particular in patients in whom renal perfusion is also compromised. Thus, an interplay between cardiac forward failure and backward failure is involved in the renal function impairment in the congestive state, presumably along with other factors. Only few data are available on the impact of intervention in volume status on the cardio-renal interaction. Sparse data in cardiac patients as well as evidence from cohorts with primary renal disease suggest that specific targeting of volume overload may be beneficial for long-term outcome, in spite of a certain further decrease in renal function, at least

  13. Radiological diagnosis of pulmonary edema in chronic renal failure

    Energy Technology Data Exchange (ETDEWEB)

    Tret' yakov, A.E. (Tsentral' naya Klinicheskaya Bol' nitsa, Moscow (USSR))

    Pulmonary edema has been revealed in 132 patients (51.6 %) during radiologic examination of 256 patients with chronic renal failure. The performance of anterio-posterior chest radiographs was in most cases necessary and quite sufficient for making diagnostic conclusions. Follow up study of patients with pulmonary edema and analysis of radiologic picture of the alterations permitted physicians to distinguish approximately 3 stages of the process development, which transit from one into another. Stage 1 involves early disorders and prodromes of pulmonary edema; Stage 2 interstitial lung edema; Stage 3 alveolar edema. The circulation enforcement of the upper lobar vessels has been the main feature of stage 1. Radiogramometry provided additional information for the pulmonary edema diagnosis. For instance, cardioradiometric data are useful for pulmonary edema diagnosis and evidence in favour of its close connection with heart disorders.

    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.

    The prevalence of chronic renal failure (CRF) at the time of kidney biopsy ranges between 5% and 37% in different renal biopsy registries. This wide variability is mainly dependent on the different definitions of CRF. In the period 1998-2006, the Triveneto Renal Biopsy Registry recorded 816 cases with CRF (defined as serum creatinine persistently > or =1.5 mg/dL), accounting for a prevalence of 27%. At the time of biopsy, the average age and glomerular filtration rate were 54 years and 41 mL/min, respectively; 70% of CRF patients are men and the prevalence of CRF increases with age. IgA nephropathy (IgAN) is the main histological form of glomerulonephritis, accounting for 23% of all cases of CRF. However, in subjects older than 65 years, membranous glomerulonephritis (MG) exceeds IgAN, thus becoming the main diagnosis in elderly patients with renal impairment. With a cutoff value for proteinuria of 3 g/day, the main diagnoses in cases with proteinuria below and above the cutoff are IgAN and MG, respectively. IgAN remains the main histological form of nephropathy throughout all levels of renal failure. These data confirm the findings of the Italian Registry of Renal Biopsies, but correspond only in part with data from other registries. The differences can to a certain extent be explained by the different criteria for the definition of renal impairment, patient selection, and differences in diagnosis among registries.

    Watermelon stomach or gastric antral vascular ectasia (GAVE) syndrome is an uncommon cause of sometimes severe upper gastro-intestinal bleeding. Essentially based on a pathognomonic endoscopic appearance, its diagnosis may be unrecognised because mistaken with portal hypertensive gastropathy, while treatment of these two entities is different. Its etiopathogeny remains still unclear, even if it is frequently associated with different systemic illnesses as hepatic cirrhosis, autoimmune disorders and chronic renal failure. The mechanism inducing these vascular ectasia may be linked with mechanical stress on submucosal vessels due to antropyloric peristaltic motility dysfunction modulated by neurohormonal vasoactive alterations. Because medical therapies are not very satisfactory, among the endoscopic modalities, argon plasma coagulation seems to be actually the first-line treatment because the most effective and safe. However, surgical antrectomy may be sometimes necessary. Recently GAVE syndrome appeared as a new adverse reaction of imatinib mesylate, one of the tyrosine kinase inhibitors used in chronic myeloid leukemia, and we report here the observation of such a pathology in one patient treated at the same time by haemodialysis and by imatinib mesylate for chronic myeloid leukemia.

    Full Text Available The levels of serum total thyroxine (TT4, triiodothyronine (TT3, free T3, (FT3 free T4 (FT4 and thyrotropin (TSH were measured in 127 clinically euthyroid patients with varying grades of chronic renal failure (CRF; and 97 healthy individuals. They were grouped as: Group I containing 93 patients on conservative management; Group II containing 34 patients on regular dialysis therapy; and Group III (normals. Group I patients showed significant decrease in TT3, TT4 and FT3 levels (p less than 0.001 as compared to Group III, whereas FT4 and TSH values in group I were not significantly altered. TT3, TT4 and FT3 levels reduced as the severity of renal damage increased. Variations in TT3, TT4, FT3, FT4 and TSH levels in Group II patients were similar to those in Group I, except for a decrease in TSH levels (p less than 0.05 as compared to normals. Several thyroid function tests are abnormal in CRF patients, however, finding of normal FT4 and TSH levels would indicate functional euthyroid status.

    Manifestations of breast abnormalities in these patients included breast calcifications, duct dilatation, fibrocystic change, rapidly enlarged multiple fibroadenomas, edema, invasive ductal cancer, extensive fibrosis, spontaneous hemorrhage, and Mondor's disease. These interesting cases we experienced are reported. Prolactin, growth hormone, and cortisol are required concurrently for normal development of mammary epithelium. Hormonal profile of chronic renal failure is different to normal person due to decreased renal clearance. The incidence of breast cancer is also increased in CRF. Metastatic soft tissue calcification is well described finding in chronic renal failure related to an increase in serum calcium phosphate product and secondary hyperparathyroidism. Kidney failure alone may increases prolactin level. The possibility of deranged hypothalamic-pituitary control mechanisms do not excluded. Impaired prolactin response to TRH stimulation has also been observed. Methyldopa and tricyclic antidepressants specifically were associated with hyperprolactinemia. Cyclosporin administration may elevate serum prolactin levels with simultaneous down regulation of prolactin receptors. Some populations of lymphocytes and fibroblasts exhibit cyclosporin receptors. Cyclosporin could potentially promote fibroadenomas by direct action, and seems to alter LH secretion.

    Aim:The aim of the present study was to investigate the effectiveness of trans-forming growth factor (TGF)-β1 antisense oligodeoxynucleotides (ODN) in ame-liorating deteriorated kidney function in rats with puromycin-induced chronic renal failure (CRF). Methods:Saline, puromycin, puromycin+TGF-β1 antisense ODN or puromycin+scrambled ODN were administered to unilaterally nephrecto-mized rats. Renal hemodynamic and excretory measurements were taken in the anaesthetized rats that had undergone surgical procedure. Results:It was ob-served that in the CRF rats, there was a marked reduction in the renal blood flow (RBF), glomerular filtration rate (GFR), severe proteinuria, and almost 6-fold in-creased fractional excretion of sodium (FE Na+) as compared to that in the control rats (all P<0.05). It was further observed that in the CRF rats, the treatment with TGF-β1 antisense, but not scrambled ODN, markedly attenuated the reduction of RBF, GFR, and proteinuria and markedly prevented the increase of the FE Na+ (all P<0.05). In addition, the renal hypertrophy in the CRF group (P<0.05 vs non-renal failure control) was markedly attenuated after treatment with TGF-1 antisense ODN (P<0.05). Focal segmental glomerulosclerosis was evident only in the un-treated and scrambled ODN-treated CRF groups. An interesting observation of this study was that in the CRF rats, although there was marked attenuating and preventive effects of the TGF-β1 antisense ODN on the deteriorated renal functions, the antisense treatment did not cause any marked change in the renal expression of TGF-β1 at the protein level. Conclusion:Collectively, the data obtained sug-gests that TGF-β1 antisense ODN possesses beneficial effects in puromycin-induced chronic renal failure and that the deterioration in morphology and im-paired renal function in this pathological state is in part dependent upon the action of TGF-β1 within the kidney.

    Manganese (Mn) is an essential trace element involved in the formation of bone and in amino acid, lipid and carbohydrate metabolism. Mn excess may be neurotoxic to humans, affecting specific areas of the central nervous system. However, relatively little is known about its physiological and/or toxicological effects, and very few data are available concerning the role of Mn in chronic renal failure (CRF). This paper describes a 12-month study of the evolution of plasma Mn levels in predialysis patients with CRF and the relationship with energy and macronutrient intake. The participants in this trial were 64 patients with CRF in predialysis and 62 healthy controls. Plasma levels of creatinine, urea, uric acid, total protein and Mn were measured. The glomerular filtration rate (GFR) was calculated using the Cockcroft-Gault index. The CRF patients had higher plasma levels of creatinine, urea, uric acid and Mn and a lower GFR than the controls. Plasma Mn was positively correlated with creatinine, plasma urea and plasma uric acid and was negatively correlated with the GFR and the intake of energy and macronutrients. In conclusion, CRF in predialysis patients is associated with increases in circulating levels of Mn.

    Objective:To evaluate hearing threshold and the severity of hearing loss at different frequencies in patients with chronic renal failure (CRF), and to analyze the role of duration of disease on hearing threshold in patients of CRF by measuring pure-tone audiometry (PTA) and distortion-product otoacoustic emission (DPOAE). Methods: There were analysed 61 subjects (122 ears) from which 12 were patients starting hemodialise (A), 24 subjects were patients undergoing hemodialise over a year (B), 15 subjects were patients undergoing conservative treatment (C) and 10 controls (D). We did hearing evaluation by testing them using tympanometry, PTA and DPOAEs. Other parameters (blood pressure, body weight, blood chemistries) were also evaluated. Results:It was found a severe high-frequency hearing loss among patients with CRF comparing to the control group. Duration on haemodialysis treatment does not seem to have a significant impact on the incidence of hearing loss, although the method of treatment may influence the impact of the disease on hearing. Hearing loss among patients with CRF seemed to deteriorate further a year after the first evaluation. Conclusions:DPOAE raised the percentages of detection of SNHL indicating that it is a better technique than the conventional PTA for evaluation of hearing acuity.

    We performed oral fat loading tests in 10 patients with chronic renal failure (CRF) on hemodialysis (5 children and 5 adults). Fat absorption was measured by hourly determination of serum triglycerides (TG), cholesterol (CHOL), and lipoproteins (LP) after oral administration of a 'milkshake' containing 50 g of fat of dairy origin. 10 age-matched healthy volunteers with normal fasting serum TG levels and 10 subjects with fasting hypertriglyceridemia served as controls. Mean fasting serum TG levels in CRF patients were elevated compared to normal controls (177.6 +/- 14.6 mg/dl, 2.0 +/- 17 mmol/l vs. 91.0 +/- 10.5 mg/dl, 1.03 +/- 12 mmol/l). 6 patients (4 adults, 2 children) had type IV LP patterns and 2 patients (both children) showed type IIb hyperlipidemia. In only 2 patients, 1 child and 1 adult were TG, CHOL and LP electrophoresis all normal. The oral fat loading test in all CRF patients showed delayed appearance of TG and chylomicrons (CHYL) in the bloodstream i.c. impaired or slow absorption of fat from the gut. In contrast to normal and hypertriglyceridemic controls, TG and CHYL levels in CRF did not decrease by 5 h after the oral fat load. This study demonstrates impaired intestinal fat absorption in children and adults with CRF.

    EDTA (calcium disodium edetate) lead mobilization and x-ray fluorescence (XRF) finger bone lead tests were done in 42 patients with chronic renal failure and without persisting lead intoxication. Nineteen of 23 patients with gout and 8 of 19 without gout had positive EDTA lead mobilization tests. Those patients with gout excreted significantly more excess lead chelate than those without gout. In the gout group 17 patients denied any childhood or industrial exposure to lead. They had a greater number of positive tests and excreted significantly more excess lead chelate than 14 patients with neither gout nor lead exposure. These results confirm that gout in the presence of chronic renal failure is a useful marker of chronic lead poisoning. Of 27 patients with positive lead mobilization tests, only 13 had elevated XRF finger bone lead concentrations (sensitivity 48%). Three of 15 patients with negative lead mobilization tests had elevated XRF finger bone lead concentrations (specificity 80%). Although the XRF finger bone lead test is a convenient noninvasive addition to the diagnostic evaluation of patients with chronic renal failure and gout, its application is limited due to the lack of sensitivity of the method.

    Hypoparathyroidism is an uncommon disease and its coexistence with chronic renal failure is quite rare. Hypocalcemia and hyperphosphatemia are seen in both diseases. Diagnosis of hypoparathyroidism may be overlooked when parathormone response is not evaluated in patients with chronic renal failure. A 19-year-old female patient who had been receiving hemodialysis for 3 years because of chronic renal failure was diagnosed as idiopathic hypoparathyroidism and hashimoto thyroiditis. When her medical records on the first admission and medical history were evaluated, hypoparathyroidism and hashimoto thyroiditis were seen to be present also when she was started hemodialysis. Idiopathic hypoparathyroidism should be suspected in case as absence of parathormone response to hypocalcemia in patients with chronic renal failure. It should be taken into consideration that hashimoto thyroiditis may accompany and required analysis should be done.

    Renal transplantation is the best therapeutic option for end-stage chronic renal disease. Assuming that it is more advisable if performed early, we aimed to show the clinical, social, and economic advantages in 70% of our patients who were dialyzed only for a short period. For this purpose, we retrospectively collected data over 28 years in 142 kidney transplants performed in patients with transplantation, 64% of our patients had no public support; however, 64% of them returned to work and got health insurance 2 months later. Full rehabilitation was achieved in all cases, including integration to the family, return to full-time work, school and university, sports, and reproduction. Immunosuppression consisted of 3 drugs, including steroids, cyclosporine, and azathioprine or mycophenolate. The cost in the 1st year, including patient and donor evaluation, surgery, immunosuppression, and follow-up, was $13,300 USD versus $22,320 for hemodialysis. We conclude that preemptive renal transplantation with renal failure, especially in developing countries such as Bolivia, where until last year, full public support for renal replacement therapy was unavailable.

    Full Text Available Objectives: To evaluate the dry eye symptoms based on objective test and subjective findings in children with chronic renal failure (CRF and to compare the results with those in healthy subjects. Materials and Methods: Thirty-four children with CRF and 89 age- and sex-matched healthy subjects were included in this prospective study. Tear break-up time (TBUT and Schirmer test, subjective symptoms (burning, foreign-body sensation, hyperemia, itching, tearing, calcification of the conjunctiva, and corneal staining were evaluated. In the study group, relation between TBUT and Schirmer test results and duration of disease, duration of dialysis, serum calcium, phosphorus, urea, creatinine, and total protein levels were recorded. For statistical analysis, t-test, chi-square test, and Pearson’s correlation test were used. Results: In the study group, burning sensation was statistically higher than in the control group. Except this, according to the other subjective tests and corneal staining, there were no significant differences between the two groups (p>0.05. Conjunctival calcification was seen in 3 patients in the study group. The mean Schirmer test result was 21.1±8.0 and 23.7±8.0 mm in the study and control groups, respectively (p=0.101. The mean TBUT was 12.5±5.2 seconds (s in the study and 16.0±5.5 s in the control groups (p=0.002. None of the disease-related variables (the mean duration of disease and dialysis, serum calcium, phosphorus, urea, creatinine, and total protein levels were associated with dry eye syndrome (p>0.05. Conclusion: TBUT was statistically significantly lower, but Schirmet test result was not significantly different between children with CRF and age- and sex-matched healthy subjects. The disease-related variables have no effect in the development of dry eyes. (Turk J Ophthalmol 2014; 44: 196-200

    Prolongation of the QTc interval, a risk factor for cardiac arrhythmias, has been observed in adult hemodialysis patients; there are few data on the QTc interval in children with chronic renal failure (CRF) and following renal transplantation (Tx). The purpose of our study was to determine the QTc interval in children with CRF and post renal Tx. Twenty children with CRF and 16 children with renal Tx who were followed at the University of California, Davis, underwent prospective EKG monitoring. The mean QTc interval in the CRF and post-Tx cohorts was normal at 407.9 ms and 408.2 ms, respectively. None of the children with CRF had QTc prolongation. Two Tx recipients had QTc prolongation; both had cardiac dilatation on echocardiography (ECHO). There was no correlation between the QTc interval and the creatinine clearance in either group. However, a significant correlation was noted between QTc prolongation and cardiac dilatation on ECHO in the Tx group (P=0.02, Fisher's exact test). In conclusion, QTc prolongation is uncommon in children with CRF and following Tx, in the absence of cardiac dilatation. However, caution is still needed before prescribing medications known to cause QTc prolongation.

The prevalence of CRF pts was registered as 4,7 per million total population (pmtp or 14,1 per million child population (pmcp while corresponding values for TRF pts were 4,5 pmtp or 13,5 pmcp. The incidence of TRF pts during the period Jan.2000-Jan.2002 was 4,35 pmcp. Boys dominated only among CRF pts (34:14; 60,4% beeing between the ages of 6 and 19 yrs while at the time of diagnosis of HBI, 33,3 % of boys were yanger than 2 yrs.The causes of CRF were: reflux nephropathy 58,3%, congenital kidney disease 16,7%, familial/hereditary 14,6% glomerulonephritis 6,2% and Willms tu 4,1%. Reflux nephropathy was also the most common underlying disease of TRF accounted for 36,9% of total cases while glomerulonephritis was responsible for 23,9 %. Reflux nephropathy was associated with neural tube defect in 53,3% and with congenital lower urinary tract obstruction in 66,7%. The most of CRF (81,25% and TRF pts (95,6% were from Serbia, the others were from Monte Negro and Republic Srpska. The most of CRF (65% and TRF (80% pts were treated in University Children’s Hospital in Belgrade. Of CRF pts 46% had serum sreatinine 100-200 μmol/l, in 11% of pts it was 400-600 μmol/l and 2% of pts were in pre-terminal CRF. One third of CRF pts had proteinuria 150-500 mg/l, and second third had proteinuria greater of 1000 mg/l. Anemia was present in 54% of CRf pts, and arterial hypertension in 56%. Hemodialysis was dominant treatment modality for TRF pts and only 23,9% had functioning transplant. Conclusion: This is the first national study of demographic characteristics of pediatric CRF in Serbia. Since its prevalence is considerably lower than that in Western and North European countries the true prevalence is some what higher. The increasing incidence of pediatric TRF from 2

    A uremic patient on hemodialysis, who had concurrent cardiomyopathy showed intense myocardial uptake of {sup 99m}Tc-methylene diphosphonate (MDP). The presumed cause of uptake in the myocardium is metastatic calcification due to hypercalcemia secondary to the renal failure. However, supplementary mechanism caused by cardiomyopathy should be considered. We describe a case with bone tracer uptake in the myocardium in the absence of infarction in a patient with chronic renal failure.

    Full Text Available Hepatitis C virus (HCV infection has come to the top of virus-induced liver diseases in many parts of the world. In Iran, it seems that HCV prevalence in general population is less than one percent, which is much lower than in most of the regional countries(1. However, the infection is emerging in Iran mostly due to problem of intravenous drug abuse and needle-sharing in the country (2, 3. The patients receiving maintenance transfusion such as chronic renal failure (CRF patients and the patients with thalassemia major are the other population who are at the high risk of HCV acquisition although compulsory blood screening has been able to remarkably decrease the HCV incidence in these patients (4. The prevalence of HCV infection among CRF patients on hemodialysis in Tehran, the capital of Iran, was around 13 percent in 2002 (5. There is no valid data regarding HCV incidence rate among CRF patients in country. However, according to the most recent official report of Management of Special Diseases and Transplantation Center (MSDT, the prevalence of HCV infection among patients on hemodialysis in the whole country has decreased from 14.4% in 1999 to 4.5% in 2005. Various reasons might be responsible for this reduction such as blood screening; developing technology of alternative modalities instead of transfusion in Iran like producing domestic Erythropoietin which has been resulted in decreasing transfusion; early transplantation; and training health staffs. On the other hand, the other reason such as mortality ofHCV infected CRF patients should not be neglected. Although there is no data in this regard in Iran, a meta-analysis, demonstrated that HCV infected patients on dialysis have an increased risk of mortality compared to HCV negative cases (6. Therefore, with the lack of data defining incidence rate in Iran, the reduction of HCV prevalence in the country should not overlook the necessity of designing a comprehensive strategy to control HCV

    The objective was to take into consideration patient concerns for an original qualitative approach to the elaboration of three therapeutic education programs (TEP) designed for chronic renal failure patients, transplantation recipients, and dialysis patients. Four discussion groups involved patients with non-terminal chronic renal failure (one group), transplantation recipients (one group), and dialysis patients (two groups). Topics discussed were patients' knowledge of the TEP and their disease and treatment, patients' expectations concerning the educative content and the organisation of the TEP. For all levels of chronic renal failure, patient expectations focused on nutrition, treatments, and the social and occupational supportive network. Patients with non-terminal renal failure also expressed their expectations concerning the comprehension of laboratory tests and the course of their renal disease. Transplantation recipients wanted to strengthen their knowledge about graft evolution and immunosuppression. Dialysis patients expressed their concerns about disease announcement and the decision for dialysis. While certain topics were common, patients were preoccupied by different problems depending on their degree of renal insufficiency. Nephrolor thus integrated these different levels of concern into the elaboration of E'Dire programs designed for non-terminal renal failure patients and EDUGREFFE for transplant recipients. The third program designed for dialysis patients is currently in the development phase.

    Simultaneous bilateral spontaneous rupture of the quadriceps tendon is a very rare condition and only a few cases have been reported in the literature. The etiology is not clear yet. But it occurs infrequently in patients with chronic metabolic disorders. A 30-year-old female patient with simultaneous bilateral spontaneous quadriceps tendon rupture visited our hospital. She had chronic renal failure and her parathyroid hormone level was elevated due to parathyroid adenoma. We report a surgical repair of both quadriceps tendons of a patient with chronic renal failure as well as management of hyperparathyroidism.

    Full Text Available Chronic renal failure is a severe clinical problem which has some significant socioeconomic impact worldwide and hemodialysis is an important way to maintain patients’ health state, but it seems difficult to get better in short time. Considering these, the aim in our research is to update and evaluate the effects of exercise on the health of patients with chronic renal failure. The databases were used to search for the relevant studies in English or Chinese. And the association between physical exercise and health state of patients with chronic renal failure has been investigated. Random-effect model was used to compare the physical function and capacity in exercise and control groups. Exercise is helpful in ameliorating the situation of blood pressure in patients with renal failure and significantly reduces VO2 in patients with renal failure. The results of subgroup analyses show that, in the age >50, physical activity can significantly reduce blood pressure in patients with renal failure. The activity program containing warm-up, strength, and aerobic exercises has benefits in blood pressure among sick people and improves their maximal oxygen consumption level. These can help patients in physical function and aerobic capacity and may give them further benefits.

    Amylase-creatinine clearance ratio (ACCR) and amylase isoenzyme clearance were determined simultaneously in patients with chronic renal failure. ACCR in patients with compensated renal failure (3.5 +/- 0.4%) was not significantly different from normals (2.6 +/- 0.2%), while that in patients with non-compensated renal failure (6.7 +/- 0.4%) was significantly higher than that in normals. Clearance ratio of pancreatic isoamylase (Amylase-1) relative to creatinine clearance (CAmy . 1/Ccr) in patients with both compensated (5.9 +/- 1.0%) and non-compensated (6.8 +/- 0.4%) renal failure was as high as that in patients with acute pancreatitis (6.6 +/- 0.5%). On the other hand, clearance ratio of salivary isoamylase (Amylase-3) relative to creatinine clearance (CAmy . 3/CCr) in patients with compensated renal failure (1.5 +/- 0.3%) was almost the same as that in normals (2.1 +/- 0.1%), while that in patients with non-compensated renal failure was 5.9 +/- 0.7%, which was significantly higher than that in normals. The present study revealed that elevated ACCR in patients with severely impaired renal function was due to the increase of the clearance ratio for both pancreatic and salivary amylase. These facts suggested that glomerular permeability and tubular reabsorption for pancreatic and salivary amylase might play an important role on ACCR in patients with severely impaired renal function.

    Full Text Available A 2-year-old male German shepherd dog in poor bodily condition was evaluated for thoracic limb lameness due to a large, firm mass medial to the left cranial scapula. Radiography revealed several large cauliflower-like mineralized masses in the craniomedial left scapula musculature, pectoral region and bilaterally in the biceps tendon sheaths. Urinalysis, haematology and serum biochemistry showed that the dog was severely anaemic, hyperphosphataemic and in chronic renal failure. The dog was euthanased and a full post mortem performed. A diagnosis of chronic renal failure with secondary hyperparathyroidism was confirmed. The mineralized masses were grossly and histopathologically consistent with a diagnosis of tumoral calcinosis. Tumoral calcinosis associated with chronic renal failure that does not involve the foot pads is rarely seen.

    Full Text Available Congenital Hepatic Fibrosis (CHF is a rare disease that affects both the liver and kidneys.  Congenital hepatic fibrosis (CHF is an autosomal recessive inherited malformation defined pathologically by a variable degree of periportal fibrosis and irregularly shaped proliferating bile ducts. Affected individuals also have impaired renal function, usually caused, in children and teenagers, by an autosomal recessive polycystic kidney disease (ARPKD. Impaired renal function associated with CHF in adults is caused by an autosomal dominant polycystic kidney disease (ADPKD. Case presentation: We report the case of a 8-year-old Iranian girlwas admitted to our hospital for evaluation ofrenal failure. In patient hepatomegaly was noted incidentally on a routine physical examination and then kidney biopsy showed global sclerosis and   A liver biopsy revealed proliferation of collagen fibres surrounding the portal area, a finding that was compatible with congenital hepatic fibrosisand our patient was scheduled for kidney and  liver transplantation. Conclusion: The relationship of ARPKD to CHF is the subject of substantial controversy. Some clinicians suggest that the two conditions represent one disorder with a range of clinical/pathological presentations Key word: Congenital Hepatic Fibrosis Polycystic Kidney Disease, CRF.

    Full Text Available Despite its long history, use of complementary and alternative medicine (CAM methods has increased dramatically only after 1990s. Up to 57% of patients with chronic renal use CAM methods.These patienys use CAM methods to overcome hypertension, fatigue, constipation, leg edema, pain, cramps, anxiety, depression, sleep disorders, to cope with symptoms such as itching, to stop the progression of kidney disease and to improve their quality of life. Methods used are herbal products and food supplements, acupressure, acupuncture, homeopathy, exercise, aromatherapy, yoga and reflexology. Nephrotoxic effect of several CAM therapies used in patients with renal impairment could disturb hemodynamics by reducing the glomerular filtration rate. For this reason, health care providers should question patients about used of CAM, methods. Communication with patients should be clear and should not act judgmental. Health care personnel should learn more about CAM methods in order to avoid unwanted situations that could develop after the application of CAM methods. Patients should be informed correctly and scientifically about these methods to avoid harmful and unnecessary uses. [Archives Medical Review Journal 2014; 23(4.000: 770-786

At the same time these patients appear to have different pathological behavior and personality disturbances as aresult of the disorders of their biological functions.AIM: The aim of this study is the examination of the psychological behavior of patients with chronic renal failure who submit themselves to recurrent heamodialysis (CRH.MATERIAL METHODS:The research was based on the completion of a questionnaire which has been used on foreigners and Greek patients who complained about chronic diseases. This questionnaire guarantees the highest reliability of all so that it will be possible to specify the negative influence of their disease upon the different sides of their life. Emphasis should be given on the fact that the personality questionnaire of Eysenck has been intensively evaluated on the Greek population as very trustworthy for secure conclusions. It included 84 questions in four different disorders (psychotism, neurotism, ex/introversion and check inversion for inaccuracies. The questionnaire has been proved very useful for the evaluation of the influence of the different interventions upon the quality of life of patients under heamodialysis. It appeared also that it was more reliable in comparison with the Sickness Impact Profile and with a test, whhb ic was aout the exercise under stress conditions. RESULTS: It has been discovered that all the three scales of control of the personality disturbances have systematically been influenced according to the control group of 138 persons from different age and sex groups. Furthermore, it has been found that the men patients underthe CRH were in lower region of the scale of neurotism while women patients appeared to be lower in the scale of psychotism. The T‐test shows that there is no important statistic difference between the two sexes according to the quality of their job. There is also no important difference

    Full Text Available The purpose of this study was to evaluate periodontal disease (PD in dogs with chronic renal failure (CRF and to compare it to PD in dogs with normal renal function (NRF. Twelve dogs with CRF and 24 dogs with NRF, all presenting dental pocket formation, were compared. In all dogs, serum creatinine, blood urea nitrogen, urine specific gravity and total red and white blood cells were determined. A complete oral examination was also performed including evaluation of bacterial plaque, gingivitis, gingival recession, pocket, calculus, dental mobility, dental loss, and ulcers. These data were used to calculate plaque index (PI, gingival index (GI and periodontal destruction index (PDI. PD was graded as mild, moderate or severe based on the results. Mild, moderate or severe PD was observed in dogs with NRF, whereas dogs with CRF presented either mild or severe PD. Dogs with NRF showed higher involvement of the maxillary teeth, whereas dogs with CRF showed a higher involvement of the mandibular teeth. Plaque index was significantly higher in dogs with NRF. It was concluded that lesion distribution and periodontal disease progression may be altered in dogs with CRF, and gingival inflammatory response differs in dogs with NRF and CRF regarding to the stage of periodontal disease.

    Background Increased renal sympathetic nerve activity can result in diuretic resistance in patients with chronic congestive heart failure.We investigated the effect of regional renal nerve blockade on the patients with chronic refractory heart failure and diuretic resistance.Methods Eighteen patients with chronic refractory heart failure were enrolled (mean age (64±11) years).The patients were randomly divided into two groups (renal nerve blockade group and standard therapy group,n=9 each).Renal nerve blockade was performed by percutaneous injection of local anaesthetic under computed tomographic guidance.Heart rate,mean arterial blood pressure,plasma and urine electrolytes,neurohormones,factional excretion of sodium (FENa),24-hour urine volume were monitored at baseline and the first 24 hours after therapy.Dyspnea and oedema were also evaluated.The major adverse cardiovascular events (MACE),plasma brain natriuretic peptide (BNP) level and left ventricular ejection fraction (LVEF) were compared between the two groups during the 3-12 months follow-up period.Results No complication was observed during the acute phase of renal nerve blockade.After renal nerve blockade,the 24-hour urine volume and FENa were significantly increased,while the level of plasma rennin,angiotensin Ⅱ,aldosterone,BNP and atrial natriuretic peptide as well as dyspnea and oedema were significantly reduced in renal nerve blockade group compared with baseline and standard therapy group.During three to 12 months of follow-up,the rate of MACE and plasma BNP level were significantly lower,while LVEF was significantly higher in renal nerve blockade group than those in standard therapy group.Conclusion Regional renal nerve blockade may be a safe and effective treatment for patients with chronic refractory heart failure.

    The whole-body 2-deoxy-2-[(18)F]fluoro-D-glucose (FDG) distribution in chronic renal failure (CRF) patients on hemodialysis would be different from that in subjects with normal renal function, because they lack urinary FDG excretion and remain in a constant volume overload. We evaluated the difference in the physiological uptake pattern of FDG between chronic renal failure patients on hemodialysis and control subjects. The subjects for this retrospective study consisted of 24 chronic renal failure patients on hemodialysis (HD group) and 24 age- and sex-matched control subjects (NC group). Standardized uptake values normalized by the body weight (SUVbw), ideal body weight (SUVibw), lean body mass (SUVlbm), and body surface area (SUVbsa) in the cerebellum, lungs, liver, gluteal muscles and subcutaneous fat, spleen, thoracolumbar spine, thoracic and abdominal aorta, and right atrium were calculated in positron emission tomography/computed tomography (PET/CT) images. SUVbw in the gluteal muscles, subcutaneous fat, spleen and right atrium was significantly higher in the HD group as compared to that in the NC group (p chronic renal failure patients on hemodialysis show significantly higher physiological FDG uptake in the soft tissues, spleen and blood pool.

    An ultrasonographic reproductive health examination of a 26-yr-old female African elephant (Loxodonta africana) revealed bilateral ureteral wall thickening and dilatation. On ultrasonographic examination, the bladder and both ureters were normal near the trigone; however, the cranial-most aspect of each ureter was dilated and thickened for a length of 30-50 cm. The same month, elevated blood creatinine (3.0 mg/dl), and urine protein-creatinine ratio (4.0) were observed. Chronic renal failure was diagnosed based on these abnormalities, and the persistent ureteral dilatation was seen on subsequent ultrasound examinations. Complete blood cell counts, serum chemistries, and urinalyses remained relatively unchanged until 24 mo after diagnosis, at which time azotemia, hypophosphatemia, and hypercalcemia (including elevated ionized calcium) developed. Hydronephrosis of both kidneys and prominent sacculation of the left ureter were noted on ultrasonographic examination. Lethargy, ventral edema, and oral mucosal ulceration acutely developed 30 mo after diagnosis. Although blood urea nitrogen remained elevated, creatinine, total calcium, and ionized calcium returned to within reference ranges at that time. Due to rapid clinical decline and grave prognosis, humane euthanasia was elected. Bilateral ureteral dilatation, dysplasia of the right kidney, and chronic nephritis of the left kidney were identified postmortem.

    Simultaneous bilateral quadriceps tendon rupture is a very rare injury mostly seen in patients with chronic renal failure or other systemic chronic diseases. Metabolic acidosis in chronic renal failure predisposes these patients to tendon degeneration. A 37-year-old woman who received hemodialysis for chronic renal failure for two years presented with complaints of severe pain in the left hip and inability to walk. She had a history of two consecutive falls in the past two months. On physical examination, there were joint spaces in both suprapatellar areas, active extension of both knees was inhibited, and movements of the left hip were quite painful. Knee ultrasonography and magnetic resonance imaging showed bilateral quadriceps tendon rupture from patellar attachment. At surgery, full-thickness quadriceps tendon tears were repaired with Tycron transpatellar suture anchors. Internal fixation was not considered for hip fracture due to the presence of chronic renal failure, so hemiarthroplasty with bipolar endoprosthesis was performed in the same session for femoral neck fracture. Six months after the operation, the patient was able to walk without support and almost regained her normal knee functions.

  4. Lactulose and renal failure.

    The introduction of lactulose as a new therapeutic agent for treatment of hepatic encephalopathy was a major breakthrough in this field. It was hypothesized that lactulose might prevent postoperative renal impairment after biliary surgery in patients with obstructive jaundice. The presumable mechanism purported was the diminished endotoxinemia by lactulose. Unfortunately, such a reno-protective effect has not been shown conclusively until now in clinical studies. In chronic renal failure lactulose is known to promote fecal excretion of water, sodium, potassium, amonium, urea, creatinine and protons. Thus, lactulose could be useful for the treatment of chronic renal failure. However, compliance to the therapy represents a major problem.

    Heart damage is widely present in patients with chronic kidney disease. Salt diet is the most important environmental factor affecting development of chronic renal failure and cardiovascular diseases. The proteins involved in chronic kidney disease -induced heart damage, especially their posttranslational modifications, remain largely unknown to date. Sprague-Dawley rats underwent 5/6 nephrectomy (chronic renal failure model) or sham operation were treated for 2 weeks with a normal-(0.4% NaCl), or high-salt (4% NaCl) diet. We employed TiO2 enrichment, iTRAQ labeling and liquid-chromatography tandem mass spectrometry strategy for phosphoproteomic profiling of left ventricular free walls in these animals. A total of 1724 unique phosphopeptides representing 2551 non-redundant phosphorylation sites corresponding to 763 phosphoproteins were identified. During normal salt feeding, 89 (54%) phosphopeptides upregulated and 76 (46%) phosphopeptides downregulated in chronic renal failure rats relative to sham rats. In chronic renal failure rats, high salt intake induced upregulation of 84 (49%) phosphopeptides and downregulation of 88 (51%) phosphopeptides. Database searches revealed that most of the identified phospholproteins were important signaling molecules such as protein kinases, receptors and phosphatases. These phospholproteins were involved in energy metabolism, cell communication, cell differentiation, cell death and other biological processes. The Search Tool for the Retrieval of Interacting Genes analysis revealed functional links among 15 significantly regulated phosphoproteins in chronic renal failure rats compared to sham group, and 23 altered phosphoproteins induced by high salt intake. The altered phosphorylation levels of two proteins involved in heart damage, lamin A and phospholamban were validated. Expression of the downstream genes of these two proteins, desmin and SERCA2a, were also analyzed.

    Full Text Available The overall incidence of amiodarone-induced thyroid dysfunction ranges from 2% to 24%. One third to half of patients with hypothyroidism have anemia due to some decrease in normal red blood cell mass and erythropoietin (EPO resistance. Therefore, for patients with chronic renal disease under medication with amiodarone, early regular thyroid function test should be checked in order to avoid amiodarone-induced hypothyroidism and EPO-resistant anemia. If amiodarone-induced hypothyroidism and EPO-resistant anemia occur in patients with chronic renal failure, early thyroxine should be given instead of waiting for spontaneous recovery by amiodarone discontinuation only. Here, we report a patient with chronic renal failure who developed EPO-resistant anemia after amiodarone treatment for arrhythmia. The hemoglobin level responded to EPO therapy rapidly after thyroxine administration and amiodarone discontinuation.

    Full Text Available Background: Antioxidant depletion occurring in chronic renal failure patients is an important cause of associated morbidity & mortality, which in turn imposes a great socioeconomic burden of health care. Early diagnosis & targeted management of this preventable deficiency may have a positive impact on the management of co morbidities associated with chronic renal failure. Aims & Objectives: To evaluate the status of antioxidants as an early indicator of cardiometabolic risk in chronic renal failure patients. Settings & Design: This was a randomised case Control study including 10 controls of either sex with normal renal function between age group 20-60 years and 15 patients of chronic renal failure on dialysis between the age group of 16 - 60 years. Methods: 12 hour fasting venous blood samples were collected from all the participants and were assayed for various antioxidants. Statistical analysis: Results were analyzed by unpaired t test, p value was determined & Correlation coefficient was calculated amongst various parameters. Results: In the present study, significantly low levels of vitamin C ( Cases: 0.367 ± 0.13 mg/dl controls: 1.324 ± 0.61 mg/dl; p < 0.01 & vitamin E (cases: 0.235 ± 0.102 mg/dl, controls (0.854 ± 0.28 mg/dl; p < 0.01 were observed in chronic renal failure patients as compared to controls. Conclusion: Diminished levels of Vitamin C & E in our study may be an indicator of increased oxidative stress which can be a responsible factor for increased incidence of cardiovascular complications. Supplementing these patients with recommended dosage of these vitamins may provide an essential tool to reduce the burden of suffering. [Int J Res Med Sci 2013; 1(2.000: 87-92

    Chronic renal failure is characterized by adaptive mechanisms secondary to the loss of functioning nephrons. Clinical and experimental studies suggest participation of gender-related hormones on renal function and progression of chronic renal failure. We evaluated the effect of castration on renal alterations in male and female Wistar control rats and after 30 days of chronic renal failure (CRF) induced by 5/6 nephrectomy. The CRF male group showed higher proteinuria. Glomerular hypertrophy was similar among groups. Podocyte morphology showed disorders of foot processes and thickening of the basement membrane in the CRF male group. The CRF female group showed fewer alterations compared to males. Castration changed the profile in CRF male animals and the filtration barrier was preserved. CRF males showed the presence of alfa-smooth muscle actin suggesting an early prefibrotic event in this group. After castration this phenomenon was not observed. Noteworthy, in females, castration exacerbated the presence of alfa-smooth muscle actin. In summary, proteinuria was higher in males and appeared early in the course of CRF, probably contributing to fibrotic events. Data were influenced by gender suggesting that male sex hormones aggravate renal alterations.

    Most babies with chronic renal failure are identified antenatally, and over half that are treated with peritoneal dialysis receive kidney transplants before school age. Most infants that develop acute renal failure have hypotension following cardiac surgery, or multiple organ failure. Sometimes the falls in glomerular filtration and urine output are physiological and reversible, and sometimes due to kidney injury, but (illogically) it is now common to define them all as having 'acute kidney injury'. Contrary to widespread opinion, careful interpretation of the plasma creatinine concentrations can provide sensitive evidence of early acute renal failure. Conservative management frequently leads to under-nutrition or fluid overload. Acute peritoneal dialysis is often technically fraught in very small patients, and haemotherapies have been limited by vascular access and anticoagulation requirements, the need to blood-prime circuits, and serious limitations in regulating fluid removal. Newer devices, including the Nidus, have been specifically designed to reduce these difficulties.

    The aim of the study was to elucidate the therapeutic effects of Atracylodes rhizome polysaccharide on adenine-induced chronic renal failure in rats. Fifty male Sprague Dawley rats were selected and randomly divided in to 5 groups (n=10 rats per group): The normal control group, the chronic renal failure pathological control group, the dexamethasone treatment group and two Atracylodes rhizome polysaccharide treatment groups, treated with two different concentrations of the polysaccharide, the Atracylodes rhizome polysaccharide high group and the Atracylodes rhizome polysaccharide low group. All the rats, except those in the normal control group were fed adenine-enriched diets, containing 10 g adenine per kg food for 3 weeks. After being fed with adenine, the dexamethasone treatment group, Atracylodes rhizome polysaccharide high group and Atracylodes rhizome polysaccharide low group rats were administered the drug orally for 2 weeks. On day 35, the kidney coefficient of the rats and the serum levels of creatinine, blood urea nitrogen, total protein and hemalbumin were determined. Subsequent to experimentation on a model of chronic renal failure in rats, the preparation was proven to be able to reduce serum levels of creatinine, blood urea nitrogen and hemalbumin levels (Prenal function. Atracylodes rhizome polysaccharide had reversed the majority of the indices of chronic renal failure in rats.

    Cerebral metabolism in chronic renal failure (CRF) patients has not been fully evaluated. This study examined cerebral metabolites in CRF, using proton magnetic resonance spectroscopy (MRS). Subjects comprised 19 CRF patients and 21 healthy volunteers. Spectra were acquired from voxels of interest positioned in the parietal gray and white matter, and concentrations of the following cerebral metabolites were measured: N-acetyl group (NA), creatine + phosphocreatine (Cr), choline-containing compounds (Cho), myo-inositol and glutamate + glutamine. Among the 19 CRF patients, 9 who were started on hemodialysis (HD) underwent careful follow-up. Proton MRS was performed before and about 2 weeks after starting HD. In six patients in whom follow-up was possible, a third MRS was performed after about 18 months. The NA/Cr ratio was not significantly changed in CRF. However, elevations in the Cho/Cr ratio were found in both gray and white matter compared with controls. To the best of our knowledge, this is the first report of positive correlations between the Cho/Cr ratio in both regions and serum osmotic pressure. (orig.)

    Porphyria cutanea tarda (PCT) can occur in HIV patients. Current evidence suggests that HIV infection may interfere with the hepatic cytochrome oxidase system, leading to porphyrin metabolism impairment. Moreover, chronic hemodialysis in renal failure may be a risk factor for PCT. In addition to the contributory factors for PCT associated to HIV infection, it is possible that porphyrin accumulation secondary to renal failure may play a role in the expression of this disease. We report a case of PCT in an HIV-1 infected patient under blood dialysis, refractory to antimalarials and controlled with desferrioxamine.

    Medical therapy has indisputably been the mainstay of management for chronic congestive heart failure. However, a significant percentage of patients continue to experience worsening heart failure (HF) symptoms despite treatment with multiple therapeutic agents. Recently, catheter-based interventional strategies that interrupt the renal sympathetic nervous system have shown promising results in providing better symptom control in patients with HF. In this article, we will review the pathophysiology of HF for better understanding of the interplay between the cardiovascular system and the kidney. Subsequently, we will briefly discuss pivotal renal denervation (RDN) therapy trials in patients with resistant hypertension and then present the available evidence on the role of RDN in HF therapy.

    Full Text Available Restrictive renal diet (low protein, low potassium, low phosphate and low salt is frequently ordered for patients with acute and chronic renal failure. This is however not necessary for all renal patients, who are at risk of compromised nutrition. Nutritional status of 60 patients (35 males, 25 females; mean age: 67±17; mean BMI: 23.4±4.6 kg/m2 with renal failure was assessed using the Subjective Global Assessment (SGA. 53%, 45% and 2% of patients were classified as well nourished, mild-moderately malnourished and severely malnourished respectively. SGA ratings had the strongest correlation with serum albumin (r=−0.226, p=0.082 compared with age (r=0.153, p=0.243, BMI (r=−0.204, p=0.139 and eGFR (r=−0.055, p=0.679. Patients with acute and chronic renal failure were equally likely to have compromised nutritional status. Similarly there was no difference in nutritional status between patients with and without dialysis (p=0.498. In conclusion, the prevalence of compromised nutritional status in hospitalized renal patients was high at 47%. Dietetic intervention is necessary to prevent further decline in nutritional status of this group of patients. Dietary restrictions should be personalized and based on biochemical profile.

    Among the various mechanisms proposed, the process of non-enzymatic glycation of proteins is believed to play an important role in the pathogenesis of chronic complications associated with renal failure. The two traditional factors found to modulate the early glycation of proteins are the prevailing concentration of glucose and half life of the protein. Among the various proteins that are known to undergo nonenzymatic glycation in vivo, hemoglobin has been the most thoroughly investigated. Determination of glycated hemoglobin in diabetic patients is currently acknowledged as the most reliable indicator for assessment of retrospective glycemic control and the planning of clinical management. The clinical utility of glycated hemoglobin measurements, however, in renal failure is controversial, given the numerous earlier studies showing no correlation between glycated hemoglobin and other indicators of blood glucose control in uremic subjects. With few exceptions, previous studies have suggested that the concentration of glycated hemoglobin was increased in uremic patients. There is documented evidence that increased glycated hemoglobin levels are found in certain non-diabetic states. So it stands to reason that hyperglycemia, although clearly being the culprit in diabetes, does not provide the complete answer to the etiology of increased early glycated products in non-diabetic conditions including chronic renal failure. This article reviews available evidence supporting increased glycation of hemoglobin in patients with chronic renal failure. Potential mechanisms for this increase are examined with special emphasis on the potential role of oxidative stress.

    Full Text Available Problem statement: We aim to evaluate the effects of acute and chronic inhibition of Neutral EndoPeptidase (NEP, by ONO-9902, on plasma and renal NEP gene expression, hemodynamic and renal parameters in rats with Chronic Heart Failure (CHF following left Coronary Artery Ligation (CAL. Approach: Forty eight male Sprague-Dawley rats (220-240 g were divided into sham and CAL groups. Myocardial infarction was induced by left CAL. All rats were further subdivided into untreated and orally treated with ONO-9902 (300 mg kg-1 day-1 from the 1st to 6th weeks after the operation. At the 1st and 6th weeks after the operation, gene expression of plasma and renal NEP, plasma ANP, cGMP and aldosterone concentrations, urine volume, Na and ANP excretion, creatinine clearance and renal cGMP generation were measured. Results: CAL leads to sodium and water retention, increased renal NEP gene expression, plasma ANP and aldosterone and decreased renal cGMP generation and plasma NEP gene expression. Acute treatment of CAL rats by ONO-9902, at the 1st week after the operation, inhibited plasma and renal NEP gene expression with increased plasma ANP, which caused diuresis, natriuresis and increased renal cGMP generation. Moreover, chronic treatment of those rats by ONO-9902 decreased plasma and renal NEP gene expression, plasma aldosterone, increased plasma ANP but non significantly, and caused diuresis, natriuresis with increased renal cGMP generation. GFR was not significantly changed before or after treatment. Conclusion: Chronic treatment with NEP inhibitor decreases Na and water retention in rats with CHF by enhancing ANP action and suppressing aldosterone secretion. So, ONO-9902 may offer a new therapeutic approach in patients with CHF.

    Full Text Available Beyazit ZencirciKahramanmaras, TurkeyBackground: Chronic renal failure is strongly associated with poor pregnancy outcome. Women dependent on hemodialysis before conception rarely achieve a successful live birth.Case presentation: A 31-year-old multiparous Turkish woman was scheduled for cesarean section under spinal anesthesia at 37 weeks and five days’ gestation because of hemorrhage due to secondary placenta previa. Spinal anesthesia with 8 mg of hyperbaric bupivacaine was successfully performed. Invasive blood pressure, central venous pressure, and heart rate were stable during the surgery. The mother returned to regular hemodialysis on the first postoperative day.Conclusion: Pregnancy is uncommon in women with chronic renal failure requiring chronic dialysis. Rates of maternal hypertension, pre-eclampsia, anemia, and infection in the pregnant chronic dialysis patient are high. However, our findings suggest that with careful, close, and effective monitoring preoperatively and intraoperatively, spinal anesthesia can be safely performed for cesarean section in patients undergoing hemodialysis.Keywords: chronic renal failure, pregnancy, spinal anesthesia, hemodialysis, placenta previa

  8. Disorders of body fluids, sodium and potassium in chronic renal failure.

    A stable volume and composition of extracellular fluid are essential for normal functioning of the body. Since the kidney is primarily responsible for regulating extracellular fluid, loss of kidney function should have catastrophic consequences. Fortunately, even with loss of more than 90 percent of renal function, a remarkable capacity to regulate body fluid volumes and sodium and potassium persists. Nevertheless, this capacity is limited to chronic renal disease and this has important consequences for clinical management of these patients. How can sodium and potassium homeostasis be assessed? Methods for evaluating the steady-state regulation of sodium include measurement of body fluids and their distribution in different compartments and measurement of exchangeable and intracellular sodium. Short-term regulation of body sodium can be assessed from measurement of sodium balance during changes in dietary salt. Potassium is predominantly contained within cells and thus the assessment of its regulation requires special emphasis on measurement of steady-state body stores and potassium distribution across cell membranes. However, the methods used to make all of these measurements require assumptions that may not hold in the altered state of uremia. This raises problems in interpretation requiring critical analysis before conclusions can be made regarding sodium and potassium homeostasis in patients with chronic renal failure. This review focuses on abnormalities of body fluids, sodium and potassium in patients with creatinine clearances of less than 20 ml/min due to chronic renal failure and the impact of conservative therapy, dialysis and renal transplantation on these patients.

    Full Text Available Introduction: Chronic renal failure (CRF is an important health problem worldwide with a tendency of annual progression. Renal failure could alter the balance of the stomatognathic system, thus conditioning the prevalence of oral diseases at its different stages. Researchers estimate that up to 90% of renal patients show oral manifestations and a wide range of bony anomalies accounting for 92% of the patients. Aims and Objectives: The aim and objective of this study was to evaluate radiographic manifestations in CRF patients and compare the findings between the stages of CRF. Materials and Methods: A longitudinal study on fifty CRF patients was conducted. Patients were divided into three stages depending on the severity of renal failure. Orthopantomograph was taken for all the subjects. Results: The study showed that 88% of the study group had positive radiographic findings. Stage IV renal failure patients had more severe manifestations as compared to Stages II and III. Conclusion: Majority of the patients had positive radiographic findings which can be one of the diagnostic markers in CRF patients.

    To correlate serologic test and pathologic findings with change of hepatic parenchymal echogenicity on ultrasound (US) in patients with chronic renal failure. From January 1995 to April 2000, among eight hundred eighty four patients with kidney transplantation due to chronic renal failure, sixty seven patients who underwent US-guided liver biopsy were selected. Change of liver echogenicity on US was analyzed, and this change was compared with serologic test and pathologic findings. Among sixty seven patients, pathologic findings of thirty four patients with the normal liver echogenicity on US revealed normal in 15 patients (44%), viral hepatitis in 18 (53%), and liver cirrhosis in one patient (3%). Meanwhile, twenty seven patients with chronic liver disease on US were pathologically confirmed as normal in 13 patients (48%), viral hepatitis in 11 (40%), liver cirrhosis in four patients (11%); six patients with cirrhotic change on US, liver cirrhosis in four patients (67%) and viral hepatitis on two patients (33%). Serologic test of thirty four patients with the normal liver echogenicity on US showed positive HBs Ag in 17 patients (50%), positive anti-HCV Ab in 11 (32%), positive in both HBs Ag and anti-HCV Ab in one (3%), and normal result in five patients (15%). In patients with chronic renal failure, it is nor enough to determine the presence of liver disease only based on change of echogenicity on US. A careful correlation with serologic test and, if needed, pathologic confirmation are recommended for the accurate preoperative evaluation of the liver.

    The aim of this study is to evaluate the factors affecting the use and frequency of use of complementary and alternative medicine among chronic renal failure patients. The use of complementary and alternative medicine in the general population and patients with chronic renal failure has increased significantly. Despite this, there is limited information concerning the use of complementary and alternative medicine among chronic renal failure patients. Cross-sectional survey. The research was carried out at the nephrology and internal medicine outpatient clinics. Two hundred and six chronic renal failure patients admitted to the outpatient clinics were included in the study. Mean outcomes measures were the frequency and type of complementary and alternative medicine use, demographic and disease-related characteristics affecting complementary and alternative medicine use and the reasons for using complementary and alternative medicine. The data were evaluated by Pearson's chi-square test and Fisher's exact test. While 2·9% of the patients had been using complementary and alternative medicine before the renal disease occurred, 25·2% of the patients reported that they had at least once used complementary and alternative medicine methods after the renal disease occurred. A significant difference was found between complementary and alternative medicine usage and age, gender, place of living, occupational status and educational background (p alternative medicine (78·3%) stated that they used such methods as a cure for their disease, 46·1% used body-mind techniques. The results of our study showed that one-fourth of the chronic renal failure patients were using complementary and alternative medicine, mainly body-mind techniques. In addition, the study proved that most of the patients do not discuss their complementary and alternative medicine usage with their doctors and nurses. It is essential that nephrology doctors and nurses should ask specific questions about

    In chronic renal failure, inorganic phosphate (Pi) retention speeds up the progression to end-stage renal disease. The current therapy for hyperphosphatemia in patients with chronic renal failure consists of dietary Pi restriction combined with administration of Pi binders, but each therapy has practical problems. Thus, the discovery of foods or nutrients that inhibit Pi absorption may be useful for the treatment of hyperphosphatemia. In the present study, we investigated whether wakame (Undaria pinnatifida) is a useful food for the prevention of hyperphosphatemia in a rat model of renal failure. Feeding a diet containing 5% wakame significantly decreased plasma and urinary Pi levels and increased the amount of fecal Pi. In addition, wakame significantly reduced plasma blood urea nitrogen and plasma Pi levels in 5/6 nephrectomized rats fed a high-Pi diet. Biochemical analyses showed that the reduction of intestinal Pi absorption is the main reason for the decrease in plasma Pi levels in rats fed a diet containing wakame. In addition, feeding alginic acid and fucoidan, major components of wakame fiber, was effective in reducing plasma Pi levels in normal rats. Finally, we concluded that wakame may be a useful food for the prevention of hyperphosphatemia in rodents.

    Full Text Available Background. This study investigated whether quercetin could alleviate vascular calcification in experimental chronic renal failure rats induced by adenine. Methods. 32 adult male Wistar rats were randomly divided into 4 groups fed normal diet, normal diet with quercetin supplementation (25 mg/kg·BW/d, 0.75% adenine diet, or adenine diet with quercetin supplementation. All rats were sacrificed after 6 weeks of intervention. Serum renal functions biomarkers and oxidative stress biomarkers were measured and status of vascular calcification in aorta was assessed. Furthermore, the induced nitric oxide synthase (iNOS/p38 mitogen activated protein kinase (p38MAPK pathway was determined to explore the potential mechanism. Results. Adenine successfully induced renal failure and vascular calcification in rat model. Quercetin supplementation reversed unfavorable changes of phosphorous, uric acid (UA and creatinine levels, malonaldehyde (MDA content, and superoxide dismutase (SOD activity in serum and the increases of calcium and alkaline phosphatase (ALP activity in the aorta (P<0.05 and attenuated calcification and calcium accumulation in the medial layer of vasculature in histopathology. Western blot analysis showed that iNOS/p38MAPK pathway was normalized by the quercetin supplementation. Conclusions. Quercetin exerted a protective effect on vascular calcification in adenine-induced chronic renal failure rats, possibly through the modulation of oxidative stress and iNOs/p38MAPK pathway.

    Full Text Available Brown tumors are unusual but serious complications of renal osteodystrophy. We retrospectively studied 12 patients presenting with chronic renal failure and brown tumor related to secondary hyperparathyroidism. Eleven patients were on chronic hemodialysis. The median duration between renal failure and end stage renal failure was 36 months (range: 12-190 months and the median duration in dialysis for 11 cases: 92 months (range: 72-252 months. The bone pain was noted in all cases (100%, pathological fracture in one case (8% and a palpable bone tumor in 10 cases (83%. Elevated serum Calcium (> 2.35 mmol/L was noted in four cases (33%, elevated serum Phosphate (> 1.78 mmol/L in ten cases (80%, elevated serum Alkaline Phosphate (> 290 UI/L in all cases and intact PTH was > 300 pg/mL in all cases with a serum median rate at 1475 pg/mL (range: 682-3687 pg/L. Subtotal parathyroidectomy was performed in all cases with a resultant decrease in size of brown tumors. We report here patient with CKD with unusual frequency and variable locations. This may be attributed tothe lack of the new calcium free phosphate binders and calcimimetics.

    In order to determine whether hypertension would develop in dogs with chronic renal failure, we performed 7/8 renal ablation in 6 healthy dogs and compared pre- and post-ablation blood pressures determined by telemetry. One month after the renal ablation, blood urea nitrogen and creatinine were significantly increased (pdogs with intact renal function. The dogs with induced renal failure and hypertension were administered an angiotensin-converting enzyme inhibitor, benazepril hydrochloride, once daily for 2 weeks at 2 mg/kg body weight, and changes in blood pressure and the renin-angiotensin-aldosterone (RAA) system were determined. During the administration of benazepril hydrochloride, blood pressure, angiotensin II and aldosterone decreased significantly (pdogs with chronic renal failure through mechanisms involving the RAA system and demonstrate that benazepril hydrochloride improves renal hypertension in dogs.

    The pattern and outcome of patients with chronic renal failure (CRF) in Kelantan, the northeastern state of Malaysia was determined. A total of 60 patients with CRF managed at the Hospital Universiti Sains Malaysia between January 1991 and June 1993 were reviewed retrospectively. The prevalence of CRF was 24.8 patients per year. The ratio of male to female patients was 1.5 : 1.0. Their mean age at presentation was 51.4 +/- 13.7 years. The cause of CRF in majority of our patients was unknown. Their mean blood urea and serum creatinine were 38.9 +/- 9.8 mmol/l and 1,154.9 +/- 458.7 mumol/l respectively. Sixty-five percent of our patients were already in end-stage renal failure (ESRF) at the time of presentation and only 53.8% of them could afford a definitive renal replacement therapy. Their mortality rate was 21.7% and majority of the death occurred in patients who were not receiving definitive renal replacement therapy. This debilitating course will continue unless the cost of renal replacement therapy is subsidised or a renal transplantation program is activated. Hence public education to encourage organ donation in this part of Malysia is necessary.

    Full Text Available Abstract Background Hyperhomocysteinemia and lipid abnormalities are commonly found in patients with chronic renal failure; both are recognized as risk factors for atherosclerosis. The homocysteine-lowering effect of pyridoxine is controversial. This study was performed to determine the effect of a high dose of pyridoxine (300 mg i.v. three times a week on plasma and red blood cell lipid profile and plasma homocysteine concentration in twelve chronic renal failure patients on regular hemodialysis. Fasting blood samples were taken at the beginning of the study (basal 1, after 30 and 60 days of treatment and 4 months after withdrawal (basal 2. Results Pyridoxine supplementation induced a significant decrease in total plasma homocysteine level and also a lowering effect in plasma total cholesterol and triglycerides. These biochemical data increased when the samples were taken at basal 2, reaching the levels obtained at the beginning of the experiment. LDL cholesterol increased whereas HDL cholesterol was reduced during the treatment. In erythrocyte membranes vitamin B6 therapy enhanced the cholesterol/phospholipid ratio as well as the fluorescence anisotropy of diphenyl-hexatriene. Conclusions We conclude that high doses of pyridoxine represent an effective strategy to ameliorate both plasma homocysteine levels and lipid profiles in chronic renal failure patients, protecting them from atherosclerosis. Further research using a long-term treatment would be necessary in an attempt to restore the fatty acid pattern and the fluidity of red cell membranes.

    Abnormal renal function is common in acute and chronic congestive heart failure (CHF) and is related to the severity of congestion. However, treatment of congestion often leads to worsening renal function. Our objective was to explore basal determinants of renal function and their response to hemodynamic interventions. Thirty-seven patients without CHF and 59 patients with chronic CHF (ejection fraction; 23 ± 8%) underwent right heart catheterization, measurements of glomerular filtration rate (GFR; inulin) and renal plasma flow (RPF; para-aminohippurate), and radiotracer estimates of renal sympathetic activity. A subset (26 without, 36 with CHF) underwent acute pharmacological intervention with dobutamine or nitroprusside. We explored the relationship between baseline and drug-induced hemodynamic changes and changes in renal function. In CHF, there was an inverse relationship among right atrial mean pressure (RAM) pressure, RPF, and GFR. By contrast, mean arterial pressure (MAP), cardiac index (CI), and measures of renal sympathetic activity were not significant predictors. In those with CHF there was also an inverse relationship among the drug-induced changes in RAM as well as pulmonary artery mean pressure and the change in GFR. Changes in MAP and CI did not predict the change in GFR in those with CHF. Baseline values and changes in RAM pressure did not correlate with GFR in those without CHF. In the CHF group there was a positive correlation between RAM pressure and renal sympathetic activity. There was also an inverse relationship among RAM pressure, GFR, and RPF in patients with chronic CHF. The observation that acute reductions in RAM pressure is associated with an increase in GFR in patients with CHF has important clinical implications.

Nestes, a prevalência de indivíduos com hiperhomocisteinemia é bastante elevada, mesmo na fase não dialítica da doença, em que a função renal está diminuída, mas ainda não é necessário tratamento dialítico. O principal fator que parece estar implicado na elevação dos níveis de homocisteína nestes pacientes com insuficiência renal crônica é a perda da massa renal, já que esta exerce uma importante função no metabolismo desse aminoácido. O tratamento da hiperhomocisteinemia na população em geral consiste na suplementação com as vitaminas envolvidas no seu metabolismo (folato, B6 e B12. Porém, em pacientes com insuficiência renal crônica, este tratamento não é completamente eficaz, pois apesar de promover a redução dos níveis de homocisteína, não alcança a normalização dos mesmos na maioria dos pacientes. Este estudo compreende uma revisão da etiologia da hiperhomocisteinemia na insuficiência renal crônica, sua relação com as doenças vasculares, seus principais determinantes e as formas de tratamento.Homocysteine is a sulfur-containing amino acid derived from the metabolism of methionine, whose abnormal accumulation in plasma is a risk factor for vascular disease in the general population and in patients with chronic renal disease. In these patients, the prevalence of individuals with hyperhomocysteinemia is very high, even in the pre-dialysis stage of the disease. The main factor that seems to be implicated on the elevation of homocysteine levels in this population is the renal mass loss, considering that the kidney has an important role in the metabolism of such amino acid. The treatment of hyperhomocysteinemia consists on supplementation of the vitamins

    Fasting levels of 5 gut hormones were studied in 30 patients with advanced uraemia (CRF), 40 undergoing regular dialysis (RD) and 555 renal transplant patients (RT). Mean values of gastrin and total glucagon were markedly elevated in CRF and RD patients compared with 20 normal subjects; there were lesser elevations in pancreatic glucagon, insulin and vasoactive intestinal peptide (VIP). Secretin levels were unchanged. In RT patients, fasting levels of VIP and pancreatic glucagon had returned to normal, while levels of gastrin, total glucagon and insulin remained slightly elevated compared with controls. Food stimulated hormone levels were measured in 18 RD patients and compared with 18 controls. After eating, RD patients failed to show the late increase in total glucagon, or the suppression of VIP and secretin seen in normal subjects; the pattern of gastrin and insulin response was similar to controls, but after the initial increase plasma levels in RD patients tended to show a slower decline. Thus involvement of the gastrointestinal tract in uraemia is associated with functional disturbance of the endocrine system of the gut.

    Full Text Available Gout (Podagra is a disorder of purine metabolism characterized by the deposition of monosodium urate crystals in joints and connective tissue and risk of deposition in kidney interstitium. Although acute gouty arthritis is familiar for most physicians, chronic gouty arthritis, which affects small joints of the hands can be difficult to distinguish from other common interphalangeal arthropathies such as rheumatoid arthritis (RA, psoriatic arthritis, and erosive osteoarthritis because of very similar presentations. Here we describe a 60-year-old male diabetic patient with pandigital, extensive subcutaneous tophaceous gout presented with uremic encephalopathy and joint deformities. He had been treated mistakenly as RA for 10 years.

    This study examined the effects of 2 wk of high-NaCl diet on kidney function and dynamic renal blood flow autoregulation (RBFA) in rats with adenine-induced chronic renal failure (ACRF). Male Sprague-Dawley rats received either chow containing adenine or were pair-fed an identical diet without adenine (controls). After 10 wk, rats were randomized to either remain on the same diet (0.6% NaCl) or to be switched to high 4% NaCl chow. Two weeks after randomization, renal clearance experiments were performed under isoflurane anesthesia and dynamic RBFA, baroreflex sensitivity (BRS), systolic arterial pressure variability (SAPV), and heart rate variability were assessed by spectral analytical techniques. Rats with ACRF showed marked reductions in glomerular filtration rate and renal blood flow (RBF), whereas mean arterial pressure and SAPV were significantly elevated. In addition, spontaneous BRS was reduced by ∼50% in ACRF animals. High-NaCl diet significantly increased transfer function fractional gain values between arterial pressure and RBF in the frequency range of the myogenic response (0.06-0.09 Hz) only in ACRF animals (0.3 ± 4.0 vs. -4.4 ± 3.8 dB; P renal failure by facilitating pressure transmission to the microvasculature.

    The renal pathology and urinary protein pattern of a 14-month-old female Bernese mountain dog with chronic renal failure was investigated. Sodium dodecyl sulphate-polyacrylamid gel electrophoresis and subsequent Western blot analysis of urine showed the presence of heavy and light chains of immunoglobulin, transferrin, albumin, vitamin D-binding protein, transthyretin and retinol-binding protein (RBP), but no excretion of Tamm-Horsfall protein (THP). Histopathological examinations of the kidneys revealed severe membranous glomerulonephritis accompanied by tubular dilatation, tubular atrophy and interstitial fibrosis. The renal expression of megalin, the main endocytic receptor for the re-uptake of proteins in proximal tubules, RBP and THP was reduced or completely absent, indicating severe tubular dysfunction. The identified urinary proteins may be of interest as additional markers for the diagnosis of juvenile nephropathy in Bernese mountain dogs.

    Chronic lower limb ischemia diminishes the quality of life and is associated with a higher risk of limb amputation and cardiovascular mortality. Coexisting chronic renal disease can modulate the response to pharmacotherapy and revascularization, and thus influence prognosis. This paper reviews current literary evidence regarding therapeutic problems observed in patients with obliterative atherosclerosis and renal failure. We reviewed articles from peer-reviewed medical journals which were published between 2000 and 2011. The poorer clinical response in the discussed patients is not only connected with the direct failure of surgical and endovascular procedures, but first of all with the high mortality of the patients. There is still a lack of sufficient evidence on the effectiveness of currently used anti-atherosclerotic agents in patients with end-stage renal failure. A certain priority is the search for an effective therapeutic strategy that would reduce mortality associated with cardiovascular conditions in this particular group of patients. Identifying patients who can benefit most from costly endovascular procedures is another vital issue.

    study was to evaluate short-term blood pressure response to two different plasma levels of enalaprilat. METHODS: As part of an open, randomized, controlled trial of the effect of high and low dosage of enalapril on the progression of renal failure, short-term blood pressure response was evaluated. Data...... pressures in the two groups were 140 (110-200) and 133 (110-165), in the high and low enalaprilat concentration groups, respectively, and after 3 months they were 135 (105-170) and 130 (105-170) mmHg (NS). Median diastolic blood pressure was 80 mmHg in each group both at baseline (65-100) and at follow......AIMS: In chronic renal failure, the clearance of most ACE inhibitors including enalapril is reduced. Hence, with conventional dosage, plasma enalaprilat may be markedly elevated. It is unclear whether this excess of drug exposure affords an improved control of blood pressure.

    Mg and its alloys have been considered as one of the most promising biodegradable medical devices, but it was still unclear whether hypermagnesemia involved health risks would occur in persons with kidney disease due to their deteriorated kidney function for Mg ions excretion from their body. In this study, we established a chronic renal failure (CRF) model in rats induced by adenine administration prior to Mg implantation, aiming to predict if CRF patients are suitable for the use of Mg implants. The results showed that Mg levels in serum, urine, feces and internal organs had no significant changes after Mg implantation for both normal and CRF rats. Biochemical indices detection and histopathological analysis in kidney, liver and heart tissue confirmed that Mg implants did not induce any extra damage in animals even with renal failure. Our study indicates that Mg based orthopaedic medical device may be considered for use in CRF patients without biosafety concerns.

    Calcification of the mitral annulus developed in a patient while undergoing dialysis. The rapid onset of events corresponded to the onset of end-stage renal failure and uncontrolled secondary hyperparathyroidism. Sequential echocardiograms verified the progression of calcification of the annulus as well as the valve. A new systolic and diastolic murmur and reduced valve orifice on two-dimensional echocardiography suggested acquired nonrheumatic mitral stenosis and insufficiency. We propose that metastatic calcium deposition rather than long-term hypertensive and degenerative effects was the predominant mechanism for massive calcification of the annulus and valve. It is suggested that M-mode echocardiography be used sequentially to follow both the occurrence and progression of calcification of the mitral annulus or valve in patients with chronic renal failure, secondary hyperparathyroidism, or both.

    Full Text Available Calciphylaxis has seldom been reported in patients with acute renal failure or in pre-dialysis patients. It also has been reported at lower calcium phosphorous products and in patients with adynamic bone disease. We report a pre-hemodialysis (HD patient with acute renal failure and biopsy-proven calciphylaxis involving multiple cutaneous sites with calcification of the perineal area resulting in dry gangrene of the penis that necessitated a partial penectomy. The patient had elevated serum calcium, phosphorous and parathyroid hormone level of 612 pg/mL. The same patient suffered subsequently from a calcium embolus that occluded his left ophthalmic artery and resulted in left eye blindness. Calciphylaxis is a devastating phenomenon and physicians should have a high clinical suspicion for it in HD patients as well as in patients with late stages of chronic kidney disease.

    Full Text Available INTRODUCTION: Chronic renal failure (CRF is decrease in glomerular filtration rate (GFR to 3 consecut ive months with multiple etiologies. CRF results in profound lipid disorder which stems largely from dysregulation of high density lipoproteins (HDL & triglyceride - rich lipoprotein metabolism. Many a time CRF patients live on hemodialysis on regular basis . Present study was done to know whether hemodialysis has any impact on the lipid profile of the CRF patients. MATERIALS AND METHODS: Study were divided into 7 groups, Group - 1: healthy controls (40, Group - 2: CRF patients who never undergone hemodialysis (40, Group - 3: CRF patients on hemodialysis (40, Group - 4: Healthy males (28, Group - 5: Healthy females (12, Group - 6: males with chronic renal failure (28, Group - 7: females with chronic renal failure (12. Sample analysed for high density lipoproteins (H DL, low density lipoproteins (LDL & very low density lipoproteins (VLDL. RESULTS: Among the various parameters tested triglyceride and VLDL levels were significantly higher in group - 2 and3 as compared to controls (p<0.0001. HDL levels were significant ly lower in group - 2 compared to Group - 1(p <0.0001. HDL level was found reduced in group - 3 as compare to Group - 2(p=0.0035. There was no significant change (p=0.132 observed in total cholesterol between healthy controls and CRF patients with hemodialysis. There is a significant change (p=0.0309 observed in LDL - c between CRF patients and controls and no significant change observed (P=0.6070 between Group - 2 and Group - 3. CONCLUSION: CRF patients are at risk of cardiovascular diseases due to the elevation of various forms of lipids. Prescribing lipid lowering treatment in CRF patients with dyslipidemias for preventing future episode of cardiovascular events and will a lso preserve renal function.

    Glycosaminoglycans (GAGs) participate in a variety of processes in the kidney, and evidence suggests that gender-related hormones participate in renal function. The aim of this study was to analyze the relationship of GAGs, gender, and proteinuria in male and female rats with chronic renal failure (CRF). GAGs were analyzed in total kidney tissue and 24-h urine of castrated (c), male (M), and female (F) Wistar control (C) rats (CM, CMc, CF, CFc) and after 30 days of CRF induced by 5/6 nephrectomy (CRFM, CRFMc, CRFF, CRFFc). Total GAG quantification and composition were determined using agarose and polyacrylamide gel electrophoresis, respectively. Renal GAGs were higher in CF compared to CM. CRFM presented an increase in renal GAGs, heparan sulfate (HS), and proteinuria, while castration reduced these parameters. However, CRFF and CRFFc groups showed a decrease in renal GAGs concomitant with an increase in proteinuria. Our results suggest that, in CRFM, sex hormones quantitatively alter GAGs, mainly HS, and possibly the glomerular filtration barrier, leading to proteinuria. The lack of this response in CRFMc, where HS did not increase, corroborates this theory. This pattern was not observed in females. Further studies of CRF are needed to clarify gender-dependent differences in HS synthesis.

  6. Fanconi syndrome and chronic renal failure in a chronic hepatitis B monoinfected patient treated with tenofovir

    Directory of Open Access Journals (Sweden)

    Pedro Magalhães-Costa

    Full Text Available Tenofovir disoproxil fumarate (TDF is one of the first-line treatment options in chronic hepatitis B (CHB. Despite its efficacy in suppressing viral load and a high resistance barrier, long life maintenance therapy is required. Registration studies demonstrated TDF to be a safe drug. However, post-marketing experience reported cases of serious nephrotoxicity associated with hypophosphatemia, osteomalacia and, even more recently, Fanconi syndrome associated with TDF therapy in CHB monoinfected patients. Here the authors report a case of a 40 year-old male, with a CHB monoinfection, that, three years after TDF therapy, developed a progressive chronic kidney disease with a serious hypophosphatemia and a secondary osteomalacia that was manifested by bone pain and multiple bone fractures. Further investigational analyses unveiled a proximal renal tubular dysfunction, which fulfilled most of the diagnostic criteria for a Fanconi syndrome. After TDF withdrawal and oral supplementation with phosphate and calcitriol, his renal function stabilized (despite not returning to normal, proximal renal tubular dysfunction abnormalities resolved as well as osteomalacia. In conclusion, physicians should be aware that, in CHB monoinfected patients under TDF therapy, serious renal damage is possible and preventable by timely monitoring serum creatinine and phosphate.

    2004-01-01

    Summary: The role of HO 1 inducer, hemin, in chronic renal failure (CRF) rats and its possible mechanism of action was studied. 5/6 subtotal nephrectomy was performed to establish chronic renal failure model. Rats were randomly assigned to 4 groups: sham-operated group, CRF group,ferrous gluconate group and hemin group. At the 10th week after operation, serum creatinine,BUN, RBC, HGB and HCT were measured. Renal pathologic changes were observed. RT-PCR and immunohistochemistry were used to detect the expression and distribution of HO-1. RT-PCR and radioimmunoassay was used to determine the expression of ET-1 in the kidney and plasma. The results showed that as compared with CRF group, serum creatinine and BUN in hemin group were reduced significantly and nephrogenic anemia was improved markedly. Glomerular mesangial proliferation and interstitial lesion were also ameliorated significantly. Hemin not only increased the expression of HO-1 but also reduced the expression of ET-1 in the kidney. The level of ET-1 protein in the plasma was also reduced after hemin treatment. Most of these indexes were not obviously changed in ferrous gluconate group. It was suggested that through inducing the expression of HO-1 and reducing the level of ET-1 in the kidney and plasma, hemin plays an important protective role in 5/6 subtotal nephrectomized rats.

    Relative low serum levels of parathormone (PTH) and low incidence of secondary hyperparathyroidism have been reported in diabetic uremic patients. The pathogenesis of this reported resistance to uremic secondary hyperparathyroidism in diabetes remains controversial. We have measured the serum C-terminal parathormone (C-PTH) renal phosphorus threshold (TmPO4) and nephrogenous cyclic AMP (N-cCAMP), in 2-hour urine collection in 22 patients with diabetic nephropathy with moderate chronic renal failure and in 27 controls with similar creatinine clearance values (18.16 +/- 9.14 and and 19.1 +/- 8.47 ml/min). In spite of the lower levels of serum C-PTH (1.07 +/- 0.43 ng/ml) diabetic patients exhibited an increased phosphaturia (TmPO4: 1.97 +/- 0.9 mg/100 ml GFR) when compared with the control group (C-PTH: 2.01 +/- 1.17 mg/ml, and TmPO4: 2.5 +/- 0.7 ml GFR). When the C-PTH values were plotted against the logarithm of creatinine clearance values, both groups showed a significant linear relationship reflecting the progressive increase in PTH when GFR fell. This progressive parathyroid stimulus was also present in diabetic patients but in a lower intensity. We believe that increased phosphaturia in diabetics with moderate chronic renal failure may be a major factor in precluding the appearance of secondary hyperparathyroidism in these patients once they reach the dialysis and transplantation programs.

    Full Text Available BACKGROUND: Patients with CRF often have signs & symptoms suggestive of thyroid dysfunctions. Prevalence of hypothyroidism in patients with terminal renal failure is 5%, in comparison with that in hospitalized patients with normal renal function . CKD is associated with higher prevalence of hypothyroidism, both overt and subclinical, but not with hyperthyroidism. In fact, the prevalence of primary hypothyroidism is mainly in the subclinical form, which increases as GFR decreases. OBJECTIVES: To estimate thyroid hormone levels i. e. T 3 , T 4 & TSH in CRF. To estimate Serum urea & creatinine for selection and categorizing the study subjects in to different grades of CRF. To study the thyroid hormone levels and thyroid abnormalities as the severity of CRF increases. MATERIALS AND METHO DS: In this study 30 male patients of aged between 40 - 70yrs . with serum creatinine >5.5mg/dl & urea >55mg/dl and dipstick test positive for protein with symptoms of chronic renal failure are taken as cases. Age and sex matched normal healthy indi vi duals ar e taken as controls. Serum Urea Estimated by DAM Method, serum creatinine is estimated by Jaffe’s method and Serum levels of T 3 , T 4 & TSH were analysed by using CLIA method. Results: T 3 , T 4 decreases and TSH increases significantly in cases compare to the controls as the severity of dieses increases . In our study 10% of patients of CRF are hypothyroid and all these hypothyroid patients belongs to serum creatinine above 6 mg/dl category. CONC LUSION: Mean of T 3 , T 4 decreases TSH increases significantly in cases compare to controls as the severity of CRF increases. The risk of hypothyroidism in chronic renal failure is very high if serum creatinine level are above 6 mg/dl.

    Full Text Available Abstract Background It has been suggested that the antioxidant properties of olmesartan (OLM, an angiotensin II type 1 receptor (AT1R blocker, contribute to renal protection rather than blood pressure lowering effects despite the fact that causal relationships between hypertension and renal artery disease exist. This study aimed to examine the hypothesis whether the antioxidative activities of OLM were correlated to arterial stiffness, reactive oxygen species and advanced glycation end products (AGEs formation in rats with chronic renal failure (CRF. Methods CRF rats were induced by 5/6 nephrectomy and randomly assigned to an OLM (10 mg/day group or a control group. Hemodynamic states, oxidative stress, renal function and AGEs were measured after 8 weeks of OLM treatment. Results All the hemodynamic derangements associated with renal and cardiovascular dysfunctions were abrogated in CRF rats receiving OLM. Decreased cardiac output was normalized compared to control (p p p p p p p  Conclusion OLM treatment could ameliorate arterial stiffness in CRF rats with concomitant inhibition of MDA and AGEs levels through the reduction of oxidative stress in aortic wall.

    Full Text Available OBJECTIVES: Atherosclerosis is seen more frequently in patients with chronic renal failure (CRF due to the oxidative stress, chronic inflammation and endothelial dysfunction. Besides lowering total and low density lipoprotein (LDL cholesterol levels, statins also lower the frequency of cardiovascular incidents in patients with chronic renal failure by their pleiotropic effects. We aimed to investigate whether atorvastatin had pleiotropic effects in dialysis patients. MATERIAL and METHODS: 21 hyperlipidemic dialysis patients (12 on hemodialysis and 9 peritoneal dialysis with LDL cholesterol levels over 130 mg/dl were included in this study. Atorvastatin was titrated and given to patients for 6 months. After LDL cholesterol level were reduced to under 100mg/day, we evaluated oxidized LDL, malondialdehyde (MDA, interleukin-6 (IL-6, high sensitive C reactive protein (hsCRP, fibrinogen, platelet count, sedimentation rate, nitric oxide (NO, Von Willebrand factor antigen (vWF ag, factor VIII (FVIII and homocysteine. RESULTS: Significant reductions were obtained in total cholesterol, LDL-cholesterol (p<0.001, triglyceride (p<0.05, oxidized LDL (p<0.001, sedimentation value (p<0.01 and platelet count (p<0.05 with atorvastatin treatment. No differences were seen in the other parameters. CONCLUSION: Atorvastatin is associated with significant improvement of lipid profile and reduction of ox-LDL, platelet count, and sedimentation in dialysis patients.

    2001-01-01

    Full Text Available Penile gangrene associated with chronic renal failure, is a rare entity. Patients usually have associated diseases like diabetes, hypertension. Gangrene occurs because the dystrophic calcific infiltration causes huninal obstruction. This is an accompaniment of generalized soft tissue calcification and bony abnormality resulting. from secondary hyperparathyroidism. Calcium phosphate product exceeds plasma solubility causing precipitation of calcium phosphate. Medical treatment may maintain the product below precipitation levels. Mortality in these patients remains high due to the severity of the associated systemic illnesses. Conservative surgical treatment is advocated in view of short life span.

    Miriplatin is a novel lipophilic platinum complex that was developed to treat hepatocellular carcinoma (HCC). Although HCC patients frequently have coexisting chronic renal failure, little prospective data are available regarding the clinical toxicity of chemotherapeutic agents used to treat HCC patients with chronic renal failure. In a phase II study, the plasma concentration of total platinum in patients who received miriplatin was very low, and no severe renal toxicity caused by miriplatin injection was reported. Here, we present three cases of HCC with stage 4 chronic renal failure who received transcatheter arterial chemotherapy with miriplatin. All cases were male, ages 72, 84, and 83 years, and had serum creatinine levels of 2.3, 1.6, and 1.9 mg/dL, respectively. Their estimated glomerular filtration rates were 21.9, 20.3, and 22.2 mL/min, respectively. All cases were treated for unresectable HCC with transcatheter arterial chemotherapy with miriplatin. No serious adverse events were observed, and serum creatinine levels did not elevate, even in the patient who experienced renal failure caused by cisplatin administration. These results might suggest that transcatheter arterial chemotherapy with miriplatin can be safely used in HCC patients with chronic renal failure.

    Full Text Available The main purpose of this investigation was to evaluate the oral and dental status of chronic renal failure (CRF patients undergoing hemodialysis at children′s Hospitals in Tehran. Fifty-three children with CRF aged 5-18 years recruited from the renal unit of children′s medical center, Tehran Hospitals for children, were studied. The decayed, missing, filled dmf, DMF, and MGI scores were recorded. The CRF children had low prevalence of dental caries, although none of the clinical diagnoses displayed the absence of gingival inflammation. Duration of dialysis and Anemia had a significant influence on the gingival condition. Especially anemia leads to severe gingivitis. The CRF children need careful monitoring and all such patient should be given oral hygiene education as topmost priority.

    Full Text Available A 63-year-old woman presented to the Orthopedic Unit of our hospital complaining of right hip pain of 6 months'duration associated with a worsening limp. Her past medical history included chronic renal insufficiency. Physical examination revealed deep pain in the iliac region and severe restriction of the right hip's articular function in the maximum degrees of range of motion. X-rays and CT scan detected an osteolytic and expansive lesion of the right supra-acetabular region with structural reabsorption of the right iliac wing. 99mTc-MDP whole-body bone scan showed an abnormal uptake in the right iliac region. Bone biopsy revealed an osteolytic lesion with multinucleated giant cells, indicating a brown tumor. Serum intact PTH was elevated (1020 pg/ml; normal values, 12 62 pg/ml, but her serum calcium was normal (total = 9.4 mg/dl, nv 8.5–10.5; ionized = 5.0 mg/dl, nv 4.2–5.4 due to the coexistence of chronic renal failure. 99mTc-MIBI scintigraphy revealed a single focus of sestamibi accumulation in the left retrosternal location, which turned out to be an intrathoracic parathyroid adenoma at surgical exploration. After surgical removal of the parathyroid adenoma, PTH levels decreased to 212 pg/ml. Three months after parathyroidectomy, the imaging studies showed complete recovery of the osteolytic lesion, thus avoiding any orthopedic surgery. This case is noteworthy because (1 primary hyperparathyroidism was not suspected due to the normocalcemia, likely attributable to the coexistence of chronic renal failure; and (2 it was associated with a brown tumor of unusual location (right supra-acetabular region.

    Full Text Available Chronic Renal Failure (CRF is a major public health problem. Early diagnosis and treatment are basic for its prognosis, and it will be fundamental for the future necessity of substitutive renal treatment. For this purpose, determining the etiology of CRF may be helpful.This study was conducted in the Nephrology Department at the Central Military Hospital in Sana’a, Yemen from 2004 to 2007; to determine the etiology of CRF in 334 patients (211 men and 123 women on regular hemodialysis.The Hypertensive Nephropathies (24% was the commonest cause of CRF. Diabetic Nephropathies (20%, Obstructive Nephropathy (16%, Chronic Pyelonephritis, Glomerulonephritis, Polycystic Kidney, Schistosomiasis (Bilharzias were less common. There were more men than women (63% vs. 37%, respectively. The mean age range of the patients was 42 years old. At study entry, 86 (29% were dialyzing via native Artery Venous Fistula (AVF and 11 (4.7% through a synthetic graft. The Temporary Catheter was the most common form of vascular access used in 272 (81% patients and AVF the second most frequent (26%. The mortality during this period was 22.9%, being the Cardiovascular Disease the main cause of death (56%, followed by Septicemia (18%. Other causes of death included Pulmonary Infection and Cirrhosis. Hypertension, late referral, smoking and Qats were the commonest co-morbid causes.According to our study we would like to include the habit of chewing Qats as a risk factor to progression of End-Stage Renal Disease (ESRD in patients with CRF.

    To assess the impact of Paidu Baoshen Pill (PBP, modified Dahuang Zhechong Pill), in retarding the procession of chronic renal failure (CRF) of stage II-III. The 283 patients of CRF stage II-III were randomly assigned to two groups, 151 patients in the treatment group treated with oral administration of PBP 3 g twice a day, and 132 patients in the control group with oxidative amylase aldehyde enveloped capsule 5-10 capsules thrice a day after meal. The course for both groups was 2 months, and the changes after 1 or 2 courses treatment in scoring of quality of life (QOL) and clinical symptoms, also in laboratory indexes including serum levels of creatinine (Cr), urea nitrogen (UN), and intrinsic creatinine clearance rate were observed. The total effective rate was 70. 86% (107/151 cases) in the treatment group and 44.70% (59/132 cases) in the control group, showing significant difference between them (X2 = 18.69, P < 0.01). Significant differences between groups were also shown in comparisons of scores of QOL and clinical symptoms after treatment. Inter-group comparison showed no difference in all the three indexes detected before treatment, but they did show statistical significance respectively after 1 and 2 courses of treatment (P < 0.05 and P < 0.01). PBP could effectively retard the progression of chronic renal failure and significantly improve the QOL of patients.

    Full Text Available Background: Pruritus is one of the most common problems in patients suffering chronic renal failure. Twenty five - 35% of predialysis patients and 60-80% of patients during dialysis complain pruritus. The exact pathophysiology of pruritus is unknown; however, some possible interactive factors include: histamine release from mast cells and basophiles, uremic skin, cutaneous mast cells proliferation, adipose cells atrophy, electrolyte imbalance, and accumulation of bile acids. Since histamine is the main proposed mediator in pruritus, the goal of this study was to evaluate the role of antihistamines in controling of pruritus of patients with chronic renal failure. This study was done as a before - after study during one year period in dialysis department of Imam Khomeini hospital. Methods: Thirty patients complied with inclusion criteria were entered in the study. Treatment strategy was: 2 weeks treatment with hydroxyzine 25 mg TDS, followed by one week wash-out period, then 2 weeks ketotifen therapy 1mg BID and finally two weeks treatment with chlorpheniramine 4mg BD following one week washout period after ketotifen therapy. Pruritus severity before and after each treatment period was evaluated with Pruritus Severity Score (PSS chart. Results: The mean PSS reduction by hydroxyzine, ketotifen and chlorpheniramine, were 33%, 4.5% and 20%, respectively. Conclusion: PSS improvement with hydroxyzine and chlorpheniramine was statistically significant (p<0.001. However, ketotifen induced pruritus reduction was not considerably significant.

    Impaired structural and metabolic integrity of the kidney in chronic renal failure (CRF) effects carnitine metabolism by means of many factors. Depletion due to hemodialysis (HD) is one of the major concerns. The aim of the study was to investigate the effects of chronic renal failure and HD on plasma free carnitine (FC) concentrations in children. Plasma FC concentrations were measured in age-matched 14 undialyzed patients, 20 dialyzed patients and 12 healthy children. In the HD group, measurements were done pre- and postdialysis and an hour after ceasing HD. None of the children have been receiving exogenous l-carnitine replacement. Plasma FC concentrations on either HD or conservative treatment were found to be decreased as compared to the healthy subjects (P < 0.001 and P = 0.001, respectively). The patients on HD had lower levels of plasma FC at the predialysis period than those on conservative treatment (P = 0.01). The FC levels significantly dropped at the postdialysis period as compared to those at the predialysis period (P < 0.001), but recovered at 1 h after ceasing HD. The mean duration of HD did not correlate with plasma FC levels at predialysis period. Children with CRF, either dialyzed or undialyzed, have decreased plasma FC levels. Hemo-dialysis treatment significantly depletes plasma FC concentrations during the procedure, but predialysis levels are reached 1 hr after ceasing HD.

Methods: This population-based retrospective cohort study included 2,931 recipients of liver transplantation performed between 1998 and 2012, enrolled from the Taiwan National Health Insurance Research Database. Patients were divided into two groups, based on the presence or absence of preoperative CRF. Results: The overall estimated survival rate of liver transplantation recipients (LTRs with preoperative CRF was significantly lower than that of patients without preoperative CRF (P=0.0085. There was no significant difference between the groups in terms of duration of intensive care unit stay, total hospital stay, bacteremia, postoperative bleeding, and pneumonia during hospitalization. Long-term adverse effects, including cerebrovascular disease and coronary heart disease, were not different between patients with versus without CRF. Conclusion: These findings suggest that LTRs with preoperative CRF have a higher rate of mortality.

    Metastatic pulmonary calcification (MPC) is common in patients with chronic renal failure. The authors experienced a patient with chronic renal failure and primary hyperparathyroidism by parathyroid adenoma accompanied with rapid progressions of MPC and alveolar hemorrhage. Recent chest radiographs, compared with previous chest radiographs, showed rapid accumulation of calcification in both upper lungs. Following up on the high-resolution CT scan after five years demonstrates more increased nodules in size and ground glass opacity. The patient was diagnosed with MPC and alveolar hemorrhage by transbronchial lung biopsy. We assumed rapid progression of MPC and alveolar hemorrhage in underlying chronic renal failures could be a primary hyperparathyroidism which may be caused by parathyroid adenoma detected incidentally. Therefore parathyroid adenoma was treated with ethanol injections. Herein, we have reported on CT findings of MPC with alveolar hemorrhage and reviewed our case along with other articles.

    Cognitive impairment, anaemia and chronic kidney disease (CKD) are associated with mortality and disability in chronic heart failure patients. We hypothesized that anaemia and CKD are independent predictors of cognitive impairment in older patients with heart failure. One hundred and ninety community-living elderly patients aged at least 70 years, treated with optimized therapy for heart failure in stable clinical conditions, were prospectively studied. They underwent clinical and multidimensional assessment. Cognitive status was assessed by the Mini Mental State Examination. Cognitive impairment was defined as the Mini Mental State Examination score adjusted by age and educational level below 24. CKD was defined as the Cockcroft-Gault glomerular filtration rate below 60  ml/min and anaemia as haemoglobin below 12  g/dl. Cognitive impairment was diagnosed in 38.9% of patients, CKD in 85.7% and anaemia in 42.6%. Age, female sex, BMI, education less than 5 years, depressive symptoms, anaemia, CKD, disability and worse quality of life were significantly associated with cognitive impairment. Cognitive impairment involved primarily global cognitive deficit, memory, mental speed, attention, calculation and language. A significant relationship between haemoglobin levels and cognitive impairment was found, with the range of 15-16.5  g/dl having the lower prevalence of cognitive impairment (19.4%). At multivariate analysis, advanced age, low education level, anaemia and CKD were independently associated with cognitive impairment. Cox analysis showed that cognitive impairment was an independent predictor of hospitalization for worsening heart failure alone and combined with all-cause death. Cognitive impairment is common in elderly heart failure patients and is independently associated with anaemia and renal dysfunction. Further studies are needed to assess whether optimal treatment of anaemia and CKD may prevent the development of cognitive impairment in heart failure

    In the last decades the survival of patients with methylmalonic aciduria has been improved. However, the overall outcome of affected patients remains disappointing. The disease course is often complicated by acute life-threatening metabolic crises, which can result in multiple organ failure or even death, resembling primary defects of mitochondrial energy metabolism. Biochemical abnormalities during metabolic derangement, such as metabolic acidosis, ketonaemia/ketonuria, lactic acidosis, hypoglycaemia and hyperammonaemia, suggest mitochondrial dysfunction. In addition, long-term complications such as chronic renal failure and neurological disease are frequently found. Neuropathophysiological studies have focused on various effects caused by accumulation of putatively toxic organic acids, the so-called 'toxic metabolite' hypothesis. In previous studies, methylmalonate (MMA) has been considered as the major neurotoxin in methylmalonic aciduria, whereas more recent studies have highlighted a synergistic inhibition of mitochondrial energy metabolism (pyruvate dehydrogenase complex, tricarboxylic acid cycle, respiratory chain, mitochondrial salvage pathway of deoxyribonucleoside triphosphate (dNTP)) induced by propionyl-CoA, 2-methylcitrate and MMA as the key pathomechanism of inherited disorders of propionate metabolism. Intracerebral accumulation of toxic metabolites ('trapping' hypothesis') is considered a biochemical risk factor for neurodegeneration. Secondary effects of mitochondrial dysfunction, such as oxidative stress and impaired mtDNA homeostasis, contribute to pathogenesis of these disorders. The underlying pathomechanisms of chronic renal insufficiency in methylmalonic acidurias are not yet understood. We hypothesize that renal and cerebral pathomechanisms share some similarities, such as an involvement of dicarboxylic acid transport. This review aims to give a comprehensive overview on recent pathomechanistic concepts for methylmalonic acidurias.

    One of the key mechanisms involved in renal Na(+) retention in chronic heart failure (CHF) is activation of epithelial Na(+) channels (ENaC) in collecting tubules. Proteolytic cleavage has an important role in activating ENaC. We hypothesized that enhanced levels of proteases in renal tubular fluid activate ENaC, resulting in renal Na(+) retention in rats with CHF. CHF was produced by left coronary artery ligation in rats. By immunoblotting, we found that several urinary serine proteases were significantly increased in CHF rats compared with sham rats (fold increases: furin 6.7, prostasin 23.6, plasminogen 2.06, and plasmin 3.57 versus sham). Similar increases were observed in urinary samples from patients with CHF. Whole-cell patch clamp was conducted in cultured renal collecting duct M-1 cells to record Na(+) currents. Protease-rich urine (from rats and patients with CHF) significantly increased the Na(+) inward current in M-1 cells. Two weeks of protease inhibitor treatment significantly abrogated the enhanced diuretic and natriuretic responses to ENaC inhibitor benzamil in rats with CHF. Increased podocyte lesions were observed in the kidneys of rats with CHF by transmission electron microscopy. Consistent with these results, podocyte damage markers desmin and podocin expressions were also increased in rats with CHF (increased ≈2-folds). These findings suggest that podocyte damage may lead to increased proteases in the tubular fluid, which in turn contributes to the enhanced renal ENaC activity, providing a novel mechanistic insight for Na(+) retention commonly observed in CHF.

    Activated charcoal (AC) is a sorbent that has been shown to remove urinary toxins like urea and indoxyl sulfate. Here, the influence of AC on kidney function of rats with experimental chronic renal failure (CRF) is investigated. CRF was induced in rats by feeding adenine (0.75%) for four weeks. As an intervention, AC was added to the feed at concentrations of 10%, 15% or 20%. Adenine treatment impaired kidney function: it lowered creatinine clearance and increased plasma concentrations of creatinine, urea, neutrophil gelatinase-associated lipocalin and vanin-1. Furthermore, it raised plasma concentrations of the uremic toxins indoxyl sulfate, phosphate and uric acid. Renal morphology was severely damaged and histopathological markers of inflammation and fibrosis were especially increased. In renal homogenates, antioxidant indices, including superoxide dismutase and catalase activity, total antioxidant capacity and reduced glutathione were adversely affected. Most of these changes were significantly ameliorated by dietary administration of AC at a concentration of 20%, while effects induced by lower doses of dietary AC on adenine nephrotoxicity were not statistically significant. The results suggest that charcoal is a useful sorbent agent in dietary adenine-induced CRF in rats and that its usability as a nephroprotective agent in human kidney disease should be studied.

    Erectile dysfunction (ED) is a common and often distressing side effect of renal failure. Uremic men of different ages report a high variety of sexual problems, including sexual hormonal pattern alterations, reduced or loss of libido, infertility, and impotence, thereby influencing their well-being. The pathogenic mechanisms include physiologic, psychologic, and organic causes. To determine the contribution of morphologic factors to impotence we studied the ultrastructure of the corpora cavernosa in 20 patients with end-stage renal disease who were treated with chronic dialysis and compared the findings with 6 individuals with no clinical history of impotence. Our results indicated that in male uremic patients with sexual disturbances there were major changes in smooth muscle cells. This was characterized by reduction of dense bodies in the cytoplasm, thick basement membranes, and increased interstitial collagen fibers with resultant reduction of cell-to-cell contact. In addition, there was thickening and lamination of basement membranes of endothelial cells and increased accumulation of collagen between nerve fibers. These alterations were more evident in patients with longer time on dialysis and were independent of type of primary renal disease. We hypothesize that ED in dialysis patients is not related to the primary disease but to the uremic state.

    Chronic kidney disease (CKD) is a covert disease. Accurate prediction of CKD progression over time is necessary for reducing its costs and mortality rates. The present study proposes an adaptive neurofuzzy inference system (ANFIS) for predicting the renal failure timeframe of CKD based on real clinical data. This study used 10-year clinical records of newly diagnosed CKD patients. The threshold value of 15 cc/kg/min/1.73 m(2) of glomerular filtration rate (GFR) was used as the marker of renal failure. A Takagi-Sugeno type ANFIS model was used to predict GFR values. Variables of age, sex, weight, underlying diseases, diastolic blood pressure, creatinine, calcium, phosphorus, uric acid, and GFR were initially selected for the predicting model. Weight, diastolic blood pressure, diabetes mellitus as underlying disease, and current GFR(t) showed significant correlation with GFRs and were selected as the inputs of model. The comparisons of the predicted values with the real data showed that the ANFIS model could accurately estimate GFR variations in all sequential periods (Normalized Mean Absolute Error lower than 5%). Despite the high uncertainties of human body and dynamic nature of CKD progression, our model can accurately predict the GFR variations at long future periods.

    Oxidative stress is an important component in the progression of chronic renal failure (CRF) and neutrophil function may be impaired by oxidative stress. Cats with CRF have increased oxidative stress and decreased neutrophil function compared with control cats. Twenty cats with previously diagnosed renal failure were compared with 10 age-matched control cats. A biochemical profile, CBC, urinalysis, antioxidant capacity, superoxide dismutase (SOD) enzyme activity, reduced to oxidized glutathione ratio (GSH : GSSG), and neutrophil phagocytosis and oxidative burst were measured. Statistical comparisons (2-tailed t-test) were reported as mean +/- standard deviation. The CRF cats had significantly higher serum blood urea nitrogen, creatinine, and phosphorus concentrations than control cats, and significantly lower PCV and urine specific gravity than control cats. The GSH : GSSG ratio was significantly higher in the CRF group (177.6 +/- 197, 61.7 +/- 33; P cats. Neutrophil oxidative burst after Escherichia coli phagocytosis, measured as an increase in mean fluorescence intensity, was significantly higher in CRF cats than controls (732 +/- 253, 524 +/- 54; P cats is consistent with activation of antioxidant defense mechanisms. It remains to be determined if supplementation with antioxidants such as SOD beyond the level of control cats would be of benefit in cats with CRF.

    The study was planned as a case-control study to examine the effects of music on some of the complications experienced by chronic renal failure (CRF) patients during hemodialysis. A total of 60 patients (30 intervention and 30 control) diagnosed with end-stage renal failure undergoing hemodialysis treatment participated in this study. The study was conducted in Manisa Merkez Efendi State Hospital Hemodialysis Unit and Manisa Özel Anemon Hemodialysis between April 2012 and July 2012. The intervention group listened 30 minutes in each session (12 total sessions) Turkish art music at the beginning of the third hour of their hemodialysis sessions. Patient Information Form and visual analog scale to assess pain, nausea, vomiting, and cramps during hemodialysis session were used. For the analysis of data, the number, percentage, chi-square test, and significance test of independent group differences between two averages were conducted. According to the findings of the study, the average of the intervention and control group ages, respectively, was 50.86 ± 11.3 and 55.13 ± 9.68. The primary duration of hemodialysis treatment for both intervention and control groups was "1 year and above" (70.0%). The intervention group's pain and nausea scores were lower than the control group for all 12 sessions. The difference between the intervention and the control group's pain scores was significant (P hemodialysis treatment.

    Enalapril and losartan reduce but not normalize sympathetic hyperactivity in patients with hypertensive chronic renal failure (CRF). This study assessed the effect of chronic eprosartan on BP and sympathetic activity, and assessed the effect of moxonidine during chronic eprosartan treatment. In 11 stable patients with CRF (creatinine clearance 47 +/- 10 ml/min), muscle sympathetic nerve activity (MSNA; peroneal nerve), BP, and baroreceptor sensitivity were measured in the absence of antihypertensive drugs (except diuretics) during chronic eprosartan therapy (600 mg for 6 wk) and in 9 patients after moxonidine (0.2 mg for 6 wk) was added. Normovolemia was controlled by diuretics and confirmed by extracellular fluid volume measurements. BP, heart rate, and MSNA were higher in patients than in 22 controls. During eprosartan therapy, mean arterial pressure (111 +/- 9 to 98 +/- 7 mmHg, P < 0.001), heart rate (71 +/- 10 to 65 +/- 8 bpm, P < 0.001), and MSNA (35 +/- 10 to 27 +/- 8 bursts/min, P < 0.001) decreased. After the addition of moxonidine (n = 9), a further reduction of mean arterial pressure to 89 +/- 7 mmHg (P < 0.05) and of MSNA to 20 +/- 10 bursts/min (P < 0.05) occurred. Sympathetic activity in patients with CRF can be normalized, and angiotensin II-independent sympathetic hyperactivity contributes to the pathogenesis of renal hypertension. Sympathetic hyperactivity is associated with poor cardiovascular outcomes, implying that reduction might be beneficial to the patients. The addition of moxonidine to angiotensin II antagonist treatment might be appropriate.

    Metabolic acidosis, a common condition in patients with renal failure, may be linked to protein-energy malnutrition (PEM) and inflammation, together also known as malnutrition-inflammation complex syndrome (MICS). Methods of serum bicarbonate measurement may misrepresent the true bicarbonate level, since the total serum carbon dioxide measurement usually overestimates the serum bicarbonate concentration. Moreover, the air transportation of blood samples to distant laboratories may lead to erroneous readings. In patients with chronic kidney disease (CKD) or end-stage renal disease (ESRD), a significant number of endocrine, musculoskeletal, and metabolic abnormalities are believed to result from acidemia. Metabolic acidosis may be related to PEM and MICS due to an increased protein catabolism, decreased protein synthesis, endocrine abnormalities including insulin resistance, decreased serum leptin level, and inflammation among individuals with renal failure. Evidence suggests that the catabolic effects of metabolic acidosis may result from an increased activity of the adenosine triphosphate (ATP)-dependent ubiquitin-proteasome and branched-chain keto acid dehydrogenase. In contrast to the metabolic studies, many epidemiologic studies in maintenance dialysis patients have indicated a paradoxically inverse association between mildly decreased serum bicarbonate and improved markers of protein-energy nutritional state. Hence metabolic acidosis may be considered as yet another element of the reverse epidemiology in ESRD patients. Interventional studies have yielded inconsistent results in CKD and ESRD patients, although in peritoneal dialysis patients, mitigating acidemia appears to more consistently improve nutritional status and reduce hospitalizations. Large-scale, prospective randomized interventional studies are needed to ascertain the potential benefits of correcting acidemia in malnourished and/or inflamed CKD and maintenance hemodialysis patients. Until then, all

    Theeffects of low-molecular-weight-chitosan (LMWC) on chronic renal failure (CRF) rats induced by adenine were investigatedin vivoand in vitro. Chitosan were hydrolyzed using chitosanase at pH 6–7 and 37℃ for 24h to obtain LMWC.In vitro, the effect of LMWC on the proliferation of renal tubular epithelial cells (RTEC) showed that it had no cytotoxic effect and could promote cell growth. For theinvivo experiment, chronic renal failure rats induced by adenine were randomly divided into control group, Niaoduqing group, and high-, medium- and low-dose LMWC groups. For each group, we detected serum creatinine (SCR), blood urea nitrogen (BUN), and total superoxide dismutase (T-SOD), glutathione oxidase (GSH-Px) activities of renal tissue, and obtained the ratio of kidney weight/body weight, pathological changes of kidney. The levels of serum SCR, BUN were higher in the adenine-induced rats than those in the controlgroup, indicating that the rat chronic renal failure model worked successfully. The re-sults after treatment showed that LMWC could reduce the SCR and BUN levels and enhance the activities/levels of T-SOD and GSH-PX in kidney compared to control group. Histopathological examination revealed that adenine-induced renal alterations were restored by LMWC at three tested dosages, especially at the low dosage of 100mgkg−1d−1.

    The aim of this study was to evaluate the properties of internal components of erythrocytes in chronic renal failure (CRF) patients undergoing hemodialysis (HD) in comparison to control subjects. For investigation of conformational state of hemoglobin and nonheme proteins (NHP) the maleimide spin label (MSL) in electron paramagnetic resonance (EPR) was applied. The studies were performed using MSL in whole cells and hemolysate as well as proteins separated by ion exchange chromatography and checked by electrophoresis. Additionally the level of -SH groups in hemolysate and isolated internal proteins of CRF erythrocytes was determined using 4,4'-dithiodipyridine. All measurements were performed before and after hemodialysis. Oxidative stress accompanying CRF/hemodialysed patients caused a significant decrease in the mobility of internal components inside erythrocytes indicated by MSL (P hemoglobins and internal nonheme proteins in erythrocytes of CRF patients.

    Chronic renal failure (CRF) causes immunosuppresion in humans and is thought to be one of the causes of noninfectious secondary immunosuppression in dogs. Hematological, biochemical, and immunological examinations were performed on blood samples obtained from dogs in various stages of CRF. The number of dogs with lymphopenia increased with the progression of clinical signs. All main subsets of lymphocytes were decreased, but more considerable reduction was detected in B-cells, Tc-cells, and NK cells. Depressed lymphocyte response to concanavalin A and pokeweed mitogen was found in dogs with severe clinical signs and lymphopenia. Our results, showing impaired immunological functions, are similar to results obtained from uremic humans, suggesting that infection may be an important complication in dogs with CRF.

    To analyze the changes in IGF-1, IGFBP-3, leptin and insulin after replacement doses of recombinant human growth hormone (rhGH) in short prepubertal children with chronic renal failure (CRF). Eleven children (3F:8M), with mean age of 9.6 years, were treated with rhGH (0.23 mg/Kg weekly for 12 months). Serum leptin, insulin, glucose, IGF-1 and IGFBP-3 were measured before, 6 and 12 months after beginning rhGH treatment. The serum levels of leptin, insulin and glucose did not vary during the treatment; normal leptin and glucose levels and high insulin were observed. There was a significant increment of IGF-1 and IGFBP-3 during the use of rhGH. The replacement doses of rhGH during 12 months in a selected group of CRF children determined an increment in IGF-1 and IGFBP-3, associated to normal serum leptin and insulin resistance.

    Full Text Available Aim: To study serum leptin level in chronic renal failure (CRF patients on different modes of management and to analyze the impact of the mode of therapy on serum leptin level. Subjects and Methods: This study was conducted on 64 patients (33males&31females with chronic renal failure divided into three groups: group I: Twenty-six patients treated conservatively and did not start dialysis yet (predialysis, group II: Twenty-four patients treated by hemodialysis, group III: Fourteen patients treated by continuous ambulatory peritoneal dialysis (CAPD. Twenty healthy subjects were included as control group. All patients and controls were subjected to full clinical examination including height and weight to calculate body mass index (BMI. Blood urea and serum creatinine were measured as renal function tests. Serum leptin was measured by EASIA and so serum insulin. Results: In predialysis and CAPD groups, there is a significant increase in leptin , leptin/ BMI and insulin in patients in comparison to control subjects. In hemodialysis group, there is a significant increase in leptin and leptin/ BMI and a non-significant increase in insulin level in patients in comparison to control subjects. Insulin is significantly correlated with leptin in the first group, while in the second and third groups there is no correlation. The highest leptin level is found in the CAPD group of patients followed by the predialysis one then the hemodialysis group. Leptin level is significantly higher in females than males in all groups. This difference remained after adjusting leptin level to BMI. No correlation was found between leptin level and age or between leptin level and renal function in the three groups of patients. No correlation was found between leptin level and the duration of dialysis in the hemodialysis and CAPD groups. Conclusion: Serum leptin is elevated in CRF patients irrespective of the type of management they are undergoing. Dialysis, has no significant

    India like any other country is facing a silent epidemic of chronic renal failure (CRF)- a facet of the health transition associated with industrialization partly fuelled by increase in sedentary lifestyle, low birth weight and malnutrition. Increasing figures by many folds seen is posing a difficult situation to overcome with respect to economy and health of the working and earning population of the nation. There is an urgent need to explore, highlight new interventions and modify modifiable risk factors as a basis for treatment strategies to prevent the development and progression of CRF. The present study was taken up to evaluate the role of trial formulation tab. Punarnavadi compound in the management of chronic renal failure. This was an open clinical comparative study in controlled circumstances wherein 67 patients were studied for two months in three groups- Group A (allopathic control), Group B (ayurvedic control) and Group C (ayurvedic test). It was a multi-centric study; patients were registered from Anandababa charitable dialysis centre, Jamnagar, Kayachikitsa O.P.D. of I.P.G.T. and R.A. Jamnagar and P. D. Patel Ayurveda hospital, Nadiad. Results were assessed on 15 parameters using Students (paired) 't' test. Group A patients showed comparatively better results in eight parameters- weight, platelet count, serum urea, serum uric acid, serum sodium, potassium, chloride and total proteins. Parameter Hemoglobin% showed better results in Group B patients and in Group C patients comparatively better results in six parameters viz.- quality of life (breathlessness, weakness, general functional capacity), total count, serum creatinine and serum calcium - were observed. Throughout the study, trial drug tab. Punarnavadi compound did not show any adverse drug reaction. The results of this study will help in developing a cheap and safe treatment for the management of CRF.

    Present study assesses the therapeutic effectiveness of Hijama (blood letting) inpatients of chronic renal failure undergoing hemodialysis for past several years with almost no urinary output.24 patients from Sindh Government Qatar Hospital Karachi were selected randomly under going dialysis 2-3 times/week for an average of 3 years under supervision of Dr. Khurram Danial, in-charge nephrologist at dialysis Centre Sindh Government Qatar Hospital Karachi after the written consent from patients. Each patient was subjected to Hijama session once a week after dialysis for a period of one year in a nearby hospital Aligarh Shifa with the consent of the ethical committee of the hospital. Serum urea, creatinine, complete blood count and electrolytes were determined prior to Hijama as baseline values and were again recorded on monthly basis for twelve months of Hijama sessions. The patient's feedback regarding quality of life after each Hijama session shows that almost all the patients reported a significant recovery from severe fatigue which they used to face during the interval between the dialysis sessions. There was significant recovery in all patients from anorexia and insomnia with the improvement in quality of life as compared to patients not undergoing Hijama. Both systolic and diastolic blood pressures were shifted towards normal in almost all patients after Hijama. Serum Creatinine level was declined significantly, while electrolyte and hematological parameters were also improved significantly. The hemoglobin of all patients undergoing Hijama was maintained near normal without any blood transfusion, which was frequently needed in patients not undergoing Hijama sessions. There was insignificant improvement in Urinary output in 2 out of 24 patients. Results of the present study suggest that Hijama may be performed safely in patients of chronic renal failure on dialysis with overall improvement in quality of life, since there was reduction in fatigue, improvement in

    The purpose of the present study was to examine the influence of different sodium loads on renin release in the hypertensive and normotensive state of chronic renal failure. Blood pressure (BP), plasma renin concentration (PRC) and exchangeable sodium (NaE) were measured in eighteen patients with advanced chronic renal failure, nine hypertensives and nine normotensives, and in seven normal subjects (a) 6 days after a fixed sodium intake of 10 mmol/day, and (b) 6 days after a fixed sodium intake of 150 mmol/day. Mean NaE was 14-19% higher in the hypertensives compared with the normotensives and values of NaE correlated significantly to values of mean BP. No significant differences were present in PRC between the groups of patients and controls on either of the sodium regimens and no correlation was found between BP and PRC. However, average decreases of PRC in the hypertensives on high sodium intake, 33-34%, were significantly lower than the corresponding values of 69-71% in the normotensive patients and controls, respectively. Furthermore, the percentage changes of PRC on high sodium intake correlated significantly to mean BP as well as to NaE. These results suggest that renin release is relatively unresponsive to different sodium intakes in hypertension following chronic renal failure. This alteration in renin release may contribute to the maintenance of hypertension in chronic renal failure, PRC being "inappropriately' increased in relationship to the sodium excess.

    Heart failure is the most frequent cardiac complication of CKD. Left ventricular hypertrophy is common and develops early in CKD, but studies have not adequately evaluated the association of left ventricular mass index with heart failure incidence among men and women with CKD. We evaluated echocardiograms of 2567 participants without self-reported heart failure enrolled in the Chronic Renal Insufficiency Cohort Study. Two-dimensional echocardiograms were performed at the year 1 study visit and interpreted at a central core laboratory. Left ventricular mass index was calculated using the linear method, indexed to height(2.7), and analyzed using sex-specific quartiles. The primary outcomes of incident heart failure and all-cause mortality were adjudicated over a median of 6.6 (interquartile range, 5.7-7.6) years. Among 2567 participants, 45% were women, and 54% were nonwhite race; mean (SD) age was 59±11 years old, and mean eGFR was 44±17 ml/min per 1.73 m(2). During a median follow-up period of 6.6 years, 262 participants developed heart failure, and 470 participants died. Compared with participants in the first quartile of left ventricular mass index, those in the highest quartile had higher rates of incident heart failure (hazard ratio, 3.96; 95% confidence interval, 1.96 to 8.02) and mortality (hazard ratio, 1.86; 95% confidence interval, 1.22 to 2.85), even after adjustment for B-type natriuretic peptide, troponin T, mineral metabolism markers, and other cardiovascular disease risk factors. Those in the lowest quartile of ejection fraction had higher rates of incident heart failure (hazard ratio, 3.01; 95% confidence interval, 1.94 to 4.67) but similar mortality rates (hazard ratio, 1.18; 95% confidence interval, 0.89 to 1.57) compared with those in the highest quartile. Diastolic dysfunction was not significantly associated with heart failure or death. Among persons with CKD and without history of cardiovascular disease, left ventricular mass index is

    Anemia and renal dysfunction (RD) are frequent complications seen in chronic heart failure (HF). However, the prevalence and interaction of these co-morbidities in a representative population of outpatients with chronic HF is poorly described. In this study, it was sought to determine the association between RD and anemia in patients with HF enrolled in a community-based HF program. Nine hundred fifty-five patients with HF due to left ventricular systolic dysfunction were investigated for the prevalence of anemia and its cause and followed for a median of 531 days. Anemia was defined as hemoglobin prevalence of anemia was 32%. Fifty-three percent of patients with and 27% of those without anemia had > or = 1 test suggesting hematinic deficiency. The prevalence of RD was 54%. Forty-one percent of patients with and 22% of patients without RD had anemia, with similar proportions associated with iron deficiency in the presence or absence of RD. Anemia and RD independently predicted a worse outcome, and this effect was additive. In conclusion, in outpatients with chronic HF, anemia and RD are common and co-exist but confer independent prognostic information. A deficiency of conventional hematinic factors may cause about 1/3 of anemia in this clinical setting.

    To explore the effect of losartan on cardiac and renal function in patients with chronic heart failure (CI-IF). Methods Sixty-five patients with CHF were divided into two groups using a randomized, control and single blind method: losartan group ( n = 30) and convention group ( n = 35 ), with a treatment course of 8 weeks for both groups. The concentrations of cystatin C (cys C) in serum, microamount albumin (MA) in urine were measured by immunoturbidimetry. The concentration of aquaporin-2 (AQP-2) was determined by enzyme-linked-immunosorbent assay (ELISA) and the heart contractile function was measured by echocardiography before and after treatment respectively. Results Comparing with routine treatment group, left ventricular end-diastolic dimension (LVEDd) decreased significantly, while left ventricular ejection fraction (LVEF) and left ventricular fractional shortening ( LVFS ) increased significantly in losartan group. The levels of cys C in serum and MA, AQP-2 in urine were significantly lower in losartan group than in routine treatment group. Conclusion Losartan can improve cardiac and renal function in patients with CHF.

    Full Text Available Sympathetic activation in chronic renal failure (CRF is a major mechanism leading to the progression of renal disease and hypertension. In the present study, we tested the hypothesis that in CRF increased reactive oxygen species (ROS production in the RVLM mediated by enhanced circulating Angiotensin II (Ang II is an important mechanism leading to hypertension in CRF. In CRF rats we found an increase in the abundance of p47phox and gp91phox mRNA within the RVLM associated with a reduction of Ang II type 1 receptors (AT1 mRNA in the brainstem compared to controls (C. Tempol but not candesartan into the RVLM decreased MAP in CRF but not in C rats. GABA into the RVLM decreased MAP in CRF (63±8 mmHg more intensely than in C (33±3 mmHg. The results suggest that increased oxidative stress within the RVLM has an important participation to maintain hypertension in CRF rats apparently independently of AT1 Ang II receptors.

    Metabolic acidosis, which is observed in salt-sensitive hypertension, is also associated with kidney injury. Alkali therapy in chronic renal failure (CRF) may ameliorate the progression of kidney disease; however, few studies have examined the effects of alkali therapy on salt sensitivity and kidney injury in CRF. We randomly administered standard diet (SD), sodium chloride with 20% casein diet (NACL), or sodium citrate with 20% casein diet (NACT) to Sprague-Dawley rats after a CRF or a sham operation. Four weeks after 5/6 nephrectomy, serum bicarbonate levels were higher in the NACT-treated group. On the pressure-natriuresis curve, NACT-treated CRF rats were more salt-resistant than NACL-treated CRF rats. Additionally, the NACT-treated CRF group showed less tubulointerstitial damage than the NACL-treated CRF group. The expression and immunoreactivity of NHE3 in the kidney in the NACT-treated CRF group were lower than those in the NACL-treated CRF group. We observed that dietary NACT as alkali therapy in CRF might improve the altered salt-sensitivity and ameliorate the progression of kidney injury compared to the NACL diet, which may be related to reduced renal NHE3 expression.

    Full Text Available Abstract Background Growth hormone-releasing hormone (GHRH plasmid-based therapy for the treatment of chronic renal failure and its complications was examined. Companion dogs (13.1 ± 0.8 years, 29.4 ± 5.01 kg and cats (13.2 ± 0.9 years, 8.5 ± 0.37 kg received a single 0.4 mg or 0.1 mg species-specific plasmid injection, respectively, intramuscularly followed by electroporation, and analyzed up to 75 days post-treatment; controls underwent electroporation without plasmid administration. Results Plasmid-treated animals showed an increase in body weight (dogs 22.5% and cats 3.2% compared to control animals, and displayed improved quality of life parameters including significant increases in appetite, activity, mentation and exercise tolerance levels. Insulin-like growth factor I (IGF-I, the downstream effector of GHRH levels were increased in the plasmid treated animals. Hematological parameters were also significantly improved. Protein metabolism changes were observed suggesting a shift from a catabolic to an anabolic state in the treated animals. Blood urea nitrogen and creatinine did not show any significant changes suggesting maintenance of kidney function whereas the control animal's renal function deteriorated. Treated animals survived longer than control animals with 70% of dogs and 80% of cats surviving until study day 75. Only 17% and 40% of the control dogs and cats, respectively, survived to day 75. Conclusion Improved quality of life, survival and general well-being indicate that further investigation is warranted, and show the potential of a plasmid-based therapy by electroporation in preventing and managing complications of renal insufficiency.

    The present study comprises of 10 dogs of either sex with primary indication of azotaemia. All the dogs were subjected to detailed clinical, haematobiochemical, urinalysis, and microbiological examination along with radiographical and ultrasonographical examination. Based on the ultrasonographic structural abnormalities, the different renal affections associated with CRF in majority of dogs were diagnosed. The different affections included "end-stage" kidneys (n = 4), hydronephrosis (n = 1), renomegaly (n = 1), nephritis (n = 1), nephrolithiasis (n = 1), nephrocalcinosis (n = 1), and renal cyst (n = 1). The significant ultrasonographic features in these affections included small kidneys with loss of corticomedullary demarcation ("end-stage" kidneys); increased cortical echogenicity (nephritis); dilation of the renal pelvis, separation of the central renal sinus with anechoic space, atrophy of renal medulla, (hydronephrosis); enlarged kidneys with increased overall echogenicity of renal cortex (renomegaly and associated nephritis); hyperechoic-mineralized structure with shadowing (nephrolithiasis); diffuse, small, multiple hyperechoic structures in the renal parenchyma with distal acoustic shadowing (nephrocalcinosis); small spherical intercortical anechoic structures fluid (renal cysts). In the present study, ultrasound proved to be a quick, convenient, and sensitive modality in detecting alterations in renal size and parenchymal architecture. All the dogs so diagnosed with CRF were rendered conservative medical treatment to control clinical signs of uraemia; maintain adequate fluid, electrolyte, and acid/base balance; provide adequate nutrition; minimize progression of renal failure.

    A 16-year-old vasectomized male ring-tailed lemur (Lemur catta) with a history of suspected chronic renal failure was evaluated because of extreme lethargy, hyperpnea, and abscess of the right pectoral scent gland. Examination of the anesthetized patient revealed an impacted right pectoral scent gland with serosanguineous exudate. A CBC and serum biochemical analysis revealed severe anemia, marked azotemia, hyperphosphatemia, and hypocalcemia. Supportive care (including fluid therapy and phosphorus binder administration) was initiated for renal failure; the affected gland was cleaned, and antimicrobials were administered. The patient received 1 blood transfusion, and darbepoetin alfa was administered weekly to stimulate RBC production. Anemia and azotemia persisted. Three months after treatment started, serum iron analysis revealed that iron deficiency was the probable cause for the lack of a consistent regenerative response to darbepoetin injections. Iron dextran injections resulted in a marked regenerative response; however, serum biochemical analysis results after the second injection were consistent with hepatic injury. Hepatic enzyme activities normalized following discontinuation of iron dextran treatment, but the lemur's Hct declined rapidly despite supplementary iron administration PO. The patient developed severe mandibular osteomyelitis and was euthanized because of poor prognosis. Postmortem evaluation of hepatic iron concentration confirmed iron deficiency. The family Lemuridae is considered prone to hemosiderosis and hemochromatosis, which delayed rapid diagnosis and treatment of the lemur's disease. Apparent hepatic injury following iron dextran injections further complicated treatment. Findings for this lemur support the use of species-specific total iron binding capacity and total serum iron and ferritin concentrations in evaluation of an animal with suspected iron deficiency.

    Full Text Available INTRODUCTION: Chronic kidney disease is a worldwide public health problem. Chronic renal failure is defined by the National Kidney Foundation as either damage or a glomerular filtration rate less than 60ml/minute/1.73m2 of body surface area for more than 3 months. The primary cause of anemia in patients with chronic renal failure is insufficient production of erythropoietin by the diseased kidneys. As there is paucity of data regarding the haematological changes in chronic renal failure in this region, the present study was aimed to achieve the following objectives. AIMS AND OBJECTIVES: 1. To assess the various hematological changes in chronic renal failure. 2. To assess the correlation between hematological and biochemical parameters. MATERIALS AND METHODS: The present study was conducted in the department of Medicine, in a tertiary care hospital, Assam for one year. STUDY DESIGN: Hospital based, single centred observational study. All patients with features of chronic renal failure, who were admitted in medicine wards, were taken randomly for the study. RESULTS: The series included 100 cases of which the highest number 37% were in the age group of 51-60 years. Male preponderance was observed with males being 65% and females 35%. Generalized weakness and swelling were the commonest symptoms observed in 76% and 74% cases and pallor, hypertension, pedal edema, ascites and acidotic breathing on examination were found in 85%, 70%, 57%, 17% and 17% cases respectively. 72% patients had serum creatinine between 5.1 to 10 mg/dl. A negative co-relationship was observed between serum creatinine and hemoglogin. All cases had anemia of which 52% had hemoglobin between 7 to 10 gm/dl, 61% had normocytic normochronic anemia and 20% had absolute iron deficiency. Diabetes was the commonest etiology in 42%, followed by hypertension 35%, undiagnosed 12%, chronic glomerulonephritis 7%, polycystic kidney and obstructive nephropathy in 2% each respectively

    Full Text Available Chronic renal failure (CRF represents the major cause of mortality in the nephro-logy unit in Ivory Coast because the means for appropriate management are lacking. The present study was performed to investigate the risk factors for CRF so that strategies for prevention could be elaborated. A case-control study was performed prospectively at the Yopougon Teaching Hos-pital in Abidjan from January 2006 to December 2006. Factors known to cause CRF were investigated in patients and controls. Their prevalence rates were compared with the general population. A total of 280 patients and 113 controls were recruited. The mean age of the patients was 37.88 ± 13.33 years and that of the controls was 41.5 ± 9.72 years. Both genders were equally represented. The main causes of CRF were chronic glomerulonephritis (47.48%, with HIV infec-tion accounting for 15% of them, and essential hypertension (HTA (25%. Essential HTA repre-sented the only factor which, if untreated, inevitably leads to CRF. Thus, our study indicates that HTA is a major public health concern. All efforts should be implemented to reduce the high prevalence of HTA and the deleterious effect of this disorder in Ivory Coast.

    Hepatitis C virus (HCV) quasispecies constitute a dynamic population in a continuous process of variation and selection. To investigate effect of the immune system on the genetic variability of HCV, we compared the hypervariable region 1 (HVR1) of immunosuppressed patients with chronic renal failure (CRF group) to immunocompetent patients with HCV chronic infection (control group). The HVR1 from ten samples of each group was amplified, cloned and sequenced. The HCV quasispecies from the control group had a higher frequency of variable sites in HVR1 (83.9 % vs 59.3 %, p quasispecies of the CRF group in the phylogenetic tree also showed the limited diversity of the quasispecies in immunosuppressed patients. Moreover, a higher variability of amino acids at positions 384, 386, 391, 394, 397, 398, 400, 405 and 410 was observed in the control group than in the CRF group, which showed a greater variability only at position 388 (p < 0.05). These data corroborates the hypothesis that the major selective pressure factor is the immune system, which promotes a high degree of diversity in the viral progeny and contributes to a constant evolution of HCV.

    Diabetic nephropathy, the most common cause of progressive chronic renal failure and end-stage renal disease, has now reached global proportions. The only means to rescue diabetic patients on dialysis is renal transplantation, a very effective therapy but severely limited by the availability of donor kidneys. Hence, we tested the role of intravenous renal cell transplantation (IRCT) on obese/diabetic Zucker/SHHF F1 hybrid (ZS) female rats with severe ischemic and diabetic nephropathy. Renal ischemia was produced by bilateral renal clamping of the renal arteries at 10 wk of age, and IRCT with genetically modified normal ZS male tubular cells was given intravenously at 15 and 20 wk of age. Rats were euthanized at 34 wk of age. IRCT with cells expressing serum amyloid A had strong and long-lasting beneficial effects on renal function and structure, including tubules and glomeruli. However, donor cells were found engrafted only in renal tubules 14 wk after the second infusion. The results indicate that IRCT with serum amyloid A-positive cells is effective in preventing the progression of chronic kidney disease in rats with diabetic and ischemic nephropathy.

    Chronic kidney disease (CKD) is increasingly prevalent in patients with chronic systolic heart failure. Therefore, evidence-based therapies are more and more being used in patients with some degree of renal dysfunction. However, most pivotal randomized clinical trials specifically excluded patients with (severe) renal dysfunction. The benefit of these evidence-based therapies in this high-risk patient group is largely unknown. This paper reviews data from randomized clinical trials in systolic heart failure and the interactions between baseline renal dysfunction and the effect of randomized treatment. It highlights that most evidence-based therapies show consistent outcome benefit in patients with moderate renal insufficiency (stage 3 CKD), whereas there are very scarce data on patients with severe (stage 4 to 5 CKD) renal insufficiency. If any, the outcome benefit might be even greater in stage 3 CKD compared with those with relatively preserved renal function. However, prescription of therapies should be individualized with consideration of possible harm and benefit, especially in those with stage 4 to 5 CKD where limited data are available.

    In patients with chronic renal failure, NaHCO3 therapy may correct or prevent acidemia. It has been proposed that the NaHCO3 required will not result in clinically significant Na retention comparable to that from similar increases in NaC1 intake. In each of ten patients with chronic renal failure, creatinine clearance (Ccr) range 2.5-16.8 ml/min, on an estimated 10-meq Na and C1 diet, electrolyte excretion was compared on NaHCO3 vs NaC1 supplements of 200 meq/day. Periods of NaHCO3 and NaC1 (in alternate order for successive patients) lasted 4 days, separated by reequilibration to base-line weight. Mean +/- SEM excretion (ex) of Na, C1, and HCO3 and deltaCcr and deltaweight (day 4-1) are compared below for the 4th day of NaC1 vs. NaHCO3 intake. Mean Ccr +/-SEM on day 4 of NaC1 and NaHCO3 were 10.8 +/-1.6 and 9.0 +/-1.4 ml/min, respectively (P less than 0.02). Mean systolic blood pressure (but not diastolic) increased significantly on NaC1 (P less than 0.05). No significant blood pressure changes were seen on NaHCO3. Net positive HCO3 balance occurred on NaHCO3 as indicated above and reflected a rise in mean serum HCO3 from 19 to 30 meq/liter (day 1 vs. 4) (P less than 0.01). Mechanisms for the greater excretion of Na on NaHCO3 may relate to C1 wasting as noted above on low C1 intake and limited HCO3 reabsorptive capacity. Thus, Na excretion by day 4 was greater on NaHCO3 than on NaHCO3 did Na excretion near intake (210 meq/day).

Objective: To characterize the impact of renal replacement therapy on the quality of life in patients with chronic renal failure. Materials and Methods: This is a literature review conducted in the Bireme database using the following descriptors: quality of life, hemodialysis and chronic renal failure. Results: The search resulted in eight complete scientific papers published between 2003 and 2010. The presence of a chronic disease, the need to commit to a long treatment, the reduction of social life and especially the physical limitations imposed by the treatment are the main causes of poor quality of life in these patients. Conclusion: The papers have showed a reduction in the quality of life of patients with chronic renal failure undergoing renal replacement therapy, indicating that the worst scores on scales that assess the quality of life are related to the sex, longer treatment duration and the age.Introdução: Entre as doenças de curso crônico, a doença renal crônica dialítica está entre as que geram maior impacto na qualidade de vida do paciente.

    Full Text Available It has been hypothesized that chronic renal failure (CRF predisposes patients to infection with intestinal protozoa. We tested this hypothesis with a matched case-control study to determine the prevalence of these protozoa and their diarrhea associated symptoms among 50 patients with CRF (cases from Taif, western Saudi Arabia. Fifty diarrheal patients without CRF were recruited in the study as controls. Participants were interviewed by a structured questionnaire and stool samples were collected. Samples were thoroughly examined with microscopy and three coproantigens detection kits. Enteric protozoa were detected in 21 cases and 14 controls. Blastocystis spp. were the most predominant parasite (16% in cases versus 8% in controls, followed by Giardia duodenalis (10% in cases versus 12% in controls and Cryptosporidium spp. (10% in cases versus 6% in controls. Cyclospora cayetanensis was identified in two cases, while Entamoeba histolytica was described in one case and one control. Intestinal parasitism was positively associated with the male gender, urban residence, and travel history. Clinical symptoms of nausea/vomiting and abdominal pain were significantly varied between the parasitized cases and controls (P value ≤ 0.05. Given the results, we recommend screening all diarrheal feces for intestinal protozoa in the study’s population, particularly those with CRF.

    It is of great importance to investigate an effective and reliable medication against chronic renal failure (CRF)-related erectile dysfunction (ED), which aims to improve patients' life qualities. The concentrations of cyclic guanosine monophosphate (cGMP) in the corpus cavernosal smooth muscle of both CRF and control rabbits were measured. The effects of various concentrations of tadalafil, papaverine, and sodium nitroprusside on the relaxation responses of corpus cavernosal smooth muscle pre-contracted with phenylephrine in CRF rabbits were observed. There was significant difference in the concentration of cGMP between CRF and control rabbits (P<0.01). Tadalafil had the greatest impacts on CRF rabbits when given the same concentration of papaverine or sodium nitroprusside and particularly significant differences were identified under the concentration levels of 10-5 and 10-4 mol/L (P<0.01). The results suggest that the cGMP concentrations of the corpus cavernosum had been greatly reduced in CRF rabbits compared with control rabbits and that tadalafil may be an ideal medication for use in the treatment of CRF-related ED.

    Forty patients with chronic renal failure (CRF) were enrolled in this study. Twelve of the 40 patients had upper gastrointestinal symptoms or signs (GI Sx). Twenty of the 40 patients had been receiving regular haemodialysis (HD) for at least 1 year prior to the study. Radionuclide-labelled solid metals were used to calculate gastric emptying times (GETs). The carbon-14 urea breath test ({sup 14}C4-UBT) was used to diagnose Helicobacter pylori (HP) infection. Among the 40 patients, 35 (88%) had an abnormal HP infection. There were no statistically significant differences in the incidence of abnormal GET among patients with HP infection and patients without HP infection. There were also no significant differences in the incidence of HP infection among patients with abnormal and normal GETs. In addition, the incidences of abnormal GET in patients with and without upper GI Sx were 83% and 89% respectively. The incidences of HP infection in patients with and without upper GI Sx were 58% and 54%, respectively. The incidences of abnormal GET in HD and non-HD patients were 95% and 80%, respectively. The incidences of HP infection in HD and non-HD patients were 45% and 65%, respectively. The differences in the incidences of abnormal GET and HP infection among HD and non-HD patients, as well as among patients with and without upper GI Sx, were not statistically significant. (orig.)

    In order to study the possibility of abnormal differentiation and proliferation of T-cell precursors in chronic renal failure (CRF), we studied T-cell colony formation in CRF patients. The two-step monolayer method, with phytohemagglutinin-P as the inducer, was used for T-cell colony formation. In our results, colony formation was markedly reduced in CRF patients in comparison with normal controls, with about half of the former showing no colony growth. All cases showed a significant increase in colony numbers with in vitro plasmapheresis (the replacement of autologous plasma in the culture system with normal AB plasma). A significant increase in colony numbers was also seen with the addition of exogenous interleukin-2 (IL-2). The addition of IL-2 in the presence of normal plasma, in particular, induced an increase in colony numbers to near the levels in normal subjects. These results suggest that T-cell precursors exist in near normal numbers in CRF patients and that there are uremic inhibitors in the plasma. A reduced production of IL-2 is also indicated. These factors may be involved in the pathogenesis of immunodeficiency in CRF patients.

    Full Text Available The aim of this study was to evaluate the properties of internal components of erythrocytes in chronic renal failure (CRF patients undergoing hemodialysis (HD in comparison to control subjects. For investigation of conformational state of hemoglobin and nonheme proteins (NHP the maleimide spin label (MSL in electron paramagnetic resonance (EPR was applied. The studies were performed using MSL in whole cells and hemolysate as well as proteins separated by ion exchange chromatography and checked by electrophoresis. Additionally the level of –SH groups in hemolysate and isolated internal proteins of CRF erythrocytes was determined using 4,4′-dithiodipyridine. All measurements were performed before and after hemodialysis. Oxidative stress accompanying CRF/hemodialysed patients caused a significant decrease in the mobility of internal components inside erythrocytes indicated by MSL (P < 0.02. The significant decrease in mobility of spin labeled HbA1c and HbA both before and after HD (P < 0.0002 as well as in nonheme proteins before hemodialysis (P < 0.05 versus control was indicated. Decrease in mobility of internal components of erythrocytes was accompanied by loss of thiols before and after hemodialysis versus control in NHP (P < 0.05, HbA1c (P < 0.0002, and HbA (P < 0.0005. These findings showed oxidative influence of hemodialysis on hemoglobins and internal nonheme proteins in erythrocytes of CRF patients.

    Full Text Available CASE REPORT An 86 year-old woman experienced chest pain, dyspnea, and dysphagia two days following orthopaedic surgery for a bimalleolus fracture of the right ankle. The patient was on prophylactic low weight molecular heparin and was affected by chronic renal failure. The chest computed tomography (CT ruled out a pulmonary embolism but showed an intramural esophageal mass involving the entire esophagus. The lesion exhibited a blood like CT attenuation content that did not enhance after contrast administration. The esophagogram with gastrografin did not reveal filling defects nor communications between lumen and mucosa. Magnetic resonance confirmed CT results and excluded an aortic dissection. All radiological findings were suggestive of intramural hematoma of the esophagus. DISCUSSION AND CONCLUSIONS Intramural hematoma of the esophagus (IHE is part of the spectrum of esophageal injuries that includes Mallory-Weiss tear and Boerhaave’s syndrome. IHE is the result of a hemorrhage within the submucosal layer. Predisposing conditions are abnormal hemostasis, traumatic events, aortic diseases. It can also occur spontaneously (idiopathic. Treatment should be conservative and includes risk factors withdrawal. The hematoma usually resolves in 1 to 3 weeks.

    Although renal trauma is increasingly managed nonoperatively, severe renovascular injuries occasionally require nephrectomy. Long-term outcomes after trauma nephrectomy are unknown. We hypothesized that the risk of end-stage renal disease (ESRD) is minimal after trauma nephrectomy. We conducted a retrospective review of the following: 1) our university-based, urban trauma center database; 2) the National Trauma Data Bank (NTDB); 3) the National Inpatient Sample (NIS); and 4) the U.S. Renal Data System (USRDS). Data were compiled to estimate the risk of ESRD after trauma nephrectomy in the United States. Of the 232 patients who sustained traumatic renal injuries at our institution from 1998 to 2007, 36 (16%) underwent a nephrectomy an average of approximately four nephrectomies per year. The NTDB reported 1780 trauma nephrectomies from 2002 to 2006, an average of 356 per year. The 2005 NIS data estimated that in the United States, over 20,000 nephrectomies are performed annually for renal cell carcinoma. The USRDS annual incidence of ESRD requiring hemodialysis is over 90,000, of which 0.1 per cent (100 per year) of renal failure is the result of traumatic or surgical loss of a kidney. Considering the large number of nephrectomies performed for cancer, we estimated the risk of trauma nephrectomy causing renal failure that requires dialysis to be 0.5 per cent. National data regarding the etiology of renal failure among patients with ESRD reveal a very low incidence of trauma nephrectomy (0.5%) as a cause; therefore, nephrectomy for trauma can be performed with little concern for long-term dialysis dependence.

    AIM: To evaluate the effects of Helicobacter pylori infection on gastric epithelial cell kinetics in patients with chronic renal failure (CRF).METHODS: Forty-four patients were enrolled in this study and divided into four groups with respect to their Helicobacter pylori (H pylori) and CRF status. Groups were labeled as follows: 1a: normal renal function, H pylori negative (n = 12), 1b: normal renal function,H pylori positive (n = 11), 2a: CRF, H pylori negative (n = 10), 2b: CRF, H pylori positive (n = 11). Upper gastrointestinal endoscopy was done in all the patients involved in the study. During endoscopical investigation,antral biopsy specimens were taken from each patient.In order to evaluate the cell apoptosis and proliferation in gastric epithelial cells, Bax and proliferating cell nuclear antigen (PCNA) labeling indexes (LI) were assessed with immunohistochemical staining method.RESULTS: For groups 1a, 1b, 2a, and 2b, mean Bax LI was identified as 34.4±13.7, 44.1±16.5, 46.3±20.5,60.7±13.8, respectively and mean PCNA LI was identified as 36.2±17.2, 53.6±25.6, 59.5±25.6, 67.2±22,respectively. When the one-way ANOVA test was applied,statistically significant differences were detected between the groups for both Bax LI (P = 0.004 <0.01) and PCNA LI (P = 0.009 <0.01). When groups were compared further in terms of Bax LI and PCNA LI with Tukey's HSD test for multiple pairwise comparisons, statistically significant difference was observed only between groups 1a and 2b (P = 0.006 <0.01).CONCLUSION: In gastric epithelial cells, expression of both the pre-apoptotic protein Bax and the proliferation marker PCNA increase with H pylori infection. This increase is more evident in patients with uremia. These findings suggest that uremia accelerates apoptosis and proliferation in gastric epithelial cells.

    Delusional infestation is an aspecific psychiatric condition manifested either as a primary psychotic disorder or a secondary disorder induced by a wide range of very different medical conditions. Both primary and secondary delusional infestations seem to respond to typical and atypical antipsychotics. The latter are considered the first-line treatment although the use of second-generation antipsychotics featuring a higher metabolic, cardiovascular, and renal tolerability is preferable in secondary cases, which often occur in patients with multiple, severe medical conditions. We report a case of a 72-year-old patient affected by delusional infestation associated with severe renal failure, metabolic syndrome, hypertensive cardiopathy, and chronic cerebrovascular disease.

    At present, the main therapy for chronic renal failure (CRF) is dialysis and renal transplantation, but neither obtains satisfactory results. Human umbilical cord mesenchymal stem cells (huMSCs) are isolated from the fetal umbilical cord which has a high self-renewal and multi-directional differentiation potential. Icariin (ICA), a kidney-tonifying Chinese Medicine can enhance the multipotency of huMSCs. Therefore, this work seeks to employ the use of ICA-treated huMSCs for the treatment of chronic renal failure. Blood urea nitrogen and creatinine (Cr) analyses showed amelioration of functional parameters in ICA-treated huMSCs for the treatment of CRF rats at 3, 7, and 14 days after transplantation. ICA-treated huMSCs can obviously increase the number of cells in injured renal tissues at 3, 7, and 14 days after transplantation by optical molecular imaging system. Hematoxylin-eosin staining demonstrated that ICA-treated huMSCs reduced the levels of fibrosis in CRF rats at 14 days after transplantation. Superoxide dismutase and Malondialdehyde analyses showed that ICA-treated huMSCs reduced the oxidative damage in CRF rats. Moreover, transplantation with ICA-treated huMSCs decreased inflammatory responses, promoted the expression of growth factors, and protected injured renal tissues. Taken together, our findings suggest that ICA-treated huMSCs could improve the kidney function in CRF rats.

    The influence of chronic renal failure on renal susceptibility to an acute ischemic insult was evaluated. Recipient Lewis rats were randomly assigned to undergo 5/6 nephrectomy (chronic renal failure, CRF) or sham operation (normal renal function, NRF). After 11 weeks, normal kidneys of Lewis donor rats were transplanted in the recipients. The outcome of the isografts was assessed. Filtration capacity of the isografts in the CRF rats was preserved to approximately one-quarter of its normal capacity on the 1st day post-transplantation, whereas it fell to 0 in the NRF rats. This was reflected by a significantly higher increase in serum creatinine in the latter group. The isografts in the CRF rats had a significantly lower degree of acute tubular necrosis and no increase in the number of macrophages and T lymphocytes in the first 24 h in contrast to the NRF rats. Epithelial regeneration and repair started earlier in the CRF group. In conclusion, the present study indicated that CRF blunted ischemia/reperfusion injury of a transplanted kidney, and that its regeneration capacity was certainly not hampered by the presence of chronic uremia. These results will be the basis for studies on modulation of early leukocyte-endothelial interactions resulting from immunological disturbances inherent to the uremic environment.

    Nearly a third of patients with acute heart failure experience concomitant renal dysfunction. This condition is often associated with increased costs of care, length of hospitalisation and high mortality. Although the clinical impact of chronic kidney disease (CKD) has been well established, the exact clinical significance of worsening renal function (WRF) during the acute and post-hospitalisation phases is not completely understood. Therefore, it is still unclear which of the common laboratory markers are able to identify WRF at an early stage. Recent studies comparing CKD with WRF showed contradictory results; this could depend on a different WRF definition, clinical characteristics, haemodynamic disorders and the presence of prior renal dysfunction in the population enrolled. The current definition of acute cardiorenal syndrome focuses on both the heart and kidney but it lacks precise laboratory marker cut-offs and a specific diagnostic approach. WRF and CKD could represent different pathophysiological mechanisms in the setting of acute heart failure; the traditional view includes reduced cardiac output with systemic and renal vasoconstriction. Nevertheless, it has become a mixed model that encompasses both forward and backward haemodynamic dysfunction. Increased central venous pressure, renal congestion with tubular obliteration, tubulo-glomerular feedback and increased abdominal pressure are all potential additional contributors. The impact of WRF on patients who experience preserved renal function and individuals affected with CKD is currently unknown. Therefore it is extremely important to understand the origins, the clinical significance and the prognostic impact of WRF on CKD.

    A 66-year-old Japanese man was diagnosed with interstitial nephritis on a renal biopsy at 45 years of age and began to receive hemodialysis at 65 years of age. He was suspected of having Fabry disease as a result of a screening study for Fabry disease performed in hemodialysis patients. He had an E66Q mutation in the α-galactosidase A gene. We conducted an electron microscopic examination of a renal biopsy specimen obtained when the patient was diagnosed with chronic renal failure at 45 years of age in order to elucidate the pathogenicity of the E66Q mutation. Interestingly, an electron microscopic examination of the renal biopsy specimen indicated no characteristic findings of Fabry disease.

    The aim of the present study was to clarify the association between lipid metabolism and the atherosclerosis in early-stage chronic renal failure at the molecular level and to explore the efficacy of decorin on chronic renal failure. Sprague Dawley rats receiving 5/6 nephrectomy and Sham surgery were divided into control and experimental groups. Sprague Dawley rats receiving 5/6 nephrectomy were divided into control and experimental groups, and the experimental group was further subdivided into rats receiving treatment with fibroblasts (FBs) transfected either with empty vector and with a decorin (DCN) gene. The dynamic levels of triglyceride (TG), total cholesterol (T-Ch) and total phospholipid (T-PL) were detected on the 10th, 30th and 60th days. The body weight, blood lipid levels, renal function and renal tissue were observed after four weeks, and transforming growth factor-βl and protein expression was detected by immunohistochemistry. In total, 4 weeks after treatment, the DCN expression in the renal tissue of rats treated with DCN-transfected FBs was significantly increased compared to that in the control rats. The results showed that the levels of the three lipids in the aortic arches were slightly elevated on the 10th day compared with those in the control group, and the TG level was significantly increased on the 30th day. The levels of T-Ch, TG and T-PL in the aortic arches were significantly elevated on the 60th day. The TG and T-Ch levels in the plasma and aortic tissues of Sprague Dawley rats receiving 5/6 nephrectomy without any treatment and after receiving treatment with FBs transfected with empty vector were significantly increased compared with those in the control group. The increased T-Ch and decreased T-PL levels in the erythrocyte membrane increased the rigidity of the erythrocyte and decreased erythrocyte deformability. In conclusion, highly expressed DCN mitigated renal fibrosis and thus delayed renal failure as well as mitigating the

    The performances of the scintigraphic localization of parathyroid adenoma have improved with the use of technetium-99m radiolabeled tracers and the development of thyroid subtraction methods. By using methoxy--isobutyl-isonitrile (MIB) alone in two phases, sensitivity and specificity are respectively O.85 and 0.92. The interest of scintigraphy compared with ultrasonography is specially marked in the situations encountered in patients with renal failure: hyperplasia, multiple or ectopic adenoma, association with thyroid nodules. However, the localisation of adenoma remains more difficult in renal failure than in primary hyperthyroidism. Scintigraphy seems to be essential for localizing adenoma and eventually hyperplasia, before surgery in patients in bad conditions or before a second operation. (authors). 26 refs., 3 figs., 2 tabs.

    Chronic renal failure can give rise to a wide spectrum of oral manifestations, owing mainly to secondary hyperparathyroidism complicating this disease. However, any systemic disease responsible for kidney failure can produce oral manifestations, which can be misdiagnosed. This report describes the case of a 40-year-old male patient referred for oral assessment before kidney and liver transplantation. He had primary hyperoxaluria complicated by end-stage renal failure and secondary hyperparathyroidism. Panoramic radiography indicated not only external root resorption, but also maxillary and mandibular radiolucencies consistent with brown tumors. Unexpectedly, histologic study of the bone biopsy specimen led to the diagnosis of jaws oxalosis. Primary hyperoxaluria is a systemic genetic disease. The affected genes are involved in glyoxylate metabolism and their deficiency results in overproduction of oxalates. Inability of the kidney to excrete oxalates leads to deposition of these crystals in almost all tissues (oxalosis) and to multiple-organ failure. Several oral findings have been described in patients with oxalosis, such as periodontal disease and root resorptions, but radiolucencies in the jaws have rarely been described. This case report is of particular interest because of the unusual location of oxalate crystal deposition in the jaws, which could be misdiagnosed in a patient with renal failure and secondary hyperparathyroidism.

    We report the case of a 55-year-old male with renal failure as the initial manifestation of interstitial and focal infiltration of the kidneys by a small B-cell lymphoma. Since three years, this patient had a history of CLL with plasmocytic differentiation and was left untreated owing to stade A Binet classification. After chemotherapy, the lymphocytosis and the adenopathies disappear and the renal function improve. Infiltration of the kidneys by non-Hodgkin small B-cell lymphoma, including chronic lymphocytic leukaemia (CLL), is usually asymptomatic, fortuitously discovered at the time of an X-ray examination or at autopsy. Association with renal failure is extremely rare. We review the reported cases of renal failure associated with lymphomatous infiltration (13 cases of CLL and five cases of lymphoplasmocytic lymphoma kappa or lambda IgM), with the following conclusions: in most cases, renal insufficiency appears in a few months and significantly disappears after chemotherapy; the renal infiltrate is usually focal in lymphoplasmocytic lymphoma and rather massive and diffuse in CLL; the neoplastic feature of a small B-cell lymphoïd infiltrate may be difficult to determine: a poorly limited, monomorphous, CD20+ CD5+ lymphoid infiltrate is lymphomatous. In case of plasmocytic differentiation, it must be looked for kappa or lambda monotypy; the type of the lymphomatous infiltrate according to the WHO 2008 classification may be difficult to determine in a small sampling of renal tissue: the renal infiltrate must be compared, if possible, with a lymph node infiltrate. Owing to its bad prognosis, mantle cell lymphoma must be distinguished from other small B-cell lymphoma like CLL/small lymphocytic lymphoma, marginal zone lymphoma and lymphoplasmocytic lymphoma.

    Simultaneous quadriceps and patellar tendon rupture is rare. Mechanical factors and coexisting systemic and local factors are taken into consideration in the pathogenesis of these ruptures. In patients with some chronic systemic diseases, simultaneous rupture can occur spontaneously or with minor traumas. We present a case of simultaneous quadriceps and patellar tendon rupture in a 21-year-old man with chronic renal failure in this report. He was treated surgically by osseotendinous repair with suture anchors and supplemental cerclage wire fixation on both sides. He regained his normal knee joint functions 18 months after the operation.

    PURPOSE OF REVIEW: Recent biochemical evidence increasingly implicates inflammatory mechanisms as precipitants of acute renal failure. In this review, we detail some of these pathways together with potential new therapeutic targets. RECENT FINDINGS: Neutrophil gelatinase-associated lipocalin appears to be a sensitive, specific and reliable biomarker of renal injury, which may be predictive of renal outcome in the perioperative setting. For estimation of glomerular filtration rate, cystatin C is superior to creatinine. No drug is definitively effective at preventing postoperative renal failure. Clinical trials of fenoldopam and atrial natriuretic peptide are, at best, equivocal. As with pharmacological preconditioning of the heart, volatile anaesthetic agents appear to offer a protective effect to the subsequently ischaemic kidney. SUMMARY: Although a greatly improved understanding of the pathophysiology of acute renal failure has offered even more therapeutic targets, the maintenance of intravascular euvolaemia and perfusion pressure is most effective at preventing new postoperative acute renal failure. In the future, strategies targeting renal regeneration after injury will use bone marrow-derived stem cells and growth factors such as insulin-like growth factor-1.

    Full Text Available The purpose of this study was to assess some mechanisms of changes in immune state, and to evaluate a role of amlodipine, a known calcium channel blocker, as a potential corrective drug in experimental chronic renal failure (CRF. An animal CRF model was produced in rats by a two-stage operative resection of 5/6 of the renal tissue. Amlodipine is used per os at a daily dose of 0.25 mg/kg for 7 days. Flow cytofluorimetric approach was used to discern peripheral blood lymphocytes: CD3+ (mainly, T lymphocytes, CD45RA+ (mainly, B cells, as well as the following cell markers: Annexin 5-FITC+/7-AAD- (early apoptosis, Annexin 5-FITC+/7-AAD+ (late apoptosis and, in part, necrotic cells. Moreover, we have measured serum concentrations of urea, creatinine, phosphate, total calcium, parathyroid hormone (PTH, IL-1β, IL-4, interferon-γ, superoxide dismutase (SOD and catalase activities. Evaluation of Th1- and Th2-dependent immune response was carried out, respectively, by detection of delayed-type hypersensitivity, and scoring the antibody-forming cells in rat spleen induced by immunization with allogeneic erythrocytes. Primary, secondary and final products of lipid peroxidation were evaluated in lipid extracts from peripheral blood lymphocytes. Changes of immune state in CRF included depression of Th1 and Th2 dependent immune response, reduced number of lymphocytes bearing T and В cell markers, increased IL-1β concentrations in blood, along with decreased amounts of IFNγ and IL-4. Probable pathogenesis of the altered immune state may be associated with increased number of peripheral lymphocytes being at early and late stages of apoptosis/necrosis, elevated blood levels of IL-1β, total calcium, parathyroid hormone, reduced concentrations of IFNγ, and increased contents of primary, secondary and final peroxidation products in peripheral blood lymphocytes, being accompanied by inhibition of the SOD and catalase activity in blood plasma

    Full Text Available The aim of this study was to evaluate the effect of Gd-chelate on renal function, iron parameters and oxidative stress in rats with CRF and a possible protective effect of the antioxidant N-Acetylcysteine (NAC. Male Wistar rats were submitted to 5/6 nephrectomy (Nx to induced CRF. An ionic-cyclic Gd (Gadoterate Meglumine was administrated (1.5 mM/KgBW, intravenously 21 days after Nx. Clearance studies were performed in 4 groups of anesthetized animals 48 hours following Gd- chelate administration: 1--Nx (n = 7; 2--Nx+NAC (n = 6; 3--Nx+Gd (n = 7; 4--Nx+NAC+Gd (4.8 g/L in drinking water, initiated 2 days before Gd-chelate administration and maintained during 4 days (n = 6. This group was compared with a control. We measured glomerular filtration rate, GFR (inulin clearance, ml/min/kg BW, proteinuria (mg/24 hs, serum iron (µg/dL; serum ferritin (ng/mL; transferrin saturation (%, TIBC (µg/dL and TBARS (nmles/ml. Normal rats treated with the same dose of Gd-chelate presented similar GFR and proteinuria when compared with normal controls, indicating that at this dose Gd-chelate is not nephrotoxic to normal rats. Gd-chelate administration to Nx-rats results in a decrease of GFR and increased proteinuria associated with a decrease in TIBC, elevation of ferritin serum levels, transferrin oversaturation and plasmatic TBARS compared with Nx-rats. The prophylactic treatment with NAC reversed the decrease in GFR and the increase in proteinuria and all alterations in iron parameters and TBARS induced by Gd-chelate. NAC administration to Nx rat did not modify the inulin clearance and iron kinetics, indicating that the ameliorating effect of NAC was specific to Gd-chelate. These results suggest that NAC can prevent Gd-chelate nephrotoxicity in patients with chronic renal failure.

    Full Text Available Objectives: Chronic renal failure (CRF is complicated by characteristic dyslipidemias. CRF patients on hemodialysis have abnormalities in lipid profile and have a high incidence of cardiovascular diseases. Lipoprotein(a [Lp(a] is now considered as a novel cardiovascular risk factor and its level is increased in CRF patients with and without hemodialysis. We sought to evaluate the pattern of lipid profile including Lp(a level in CRF patients with and without hemodialysis. Methodology: Study were divided into 3 groups, Group-I: healthy controls (30, Group-II: CRF patients who never undergone hemodialysis (30 and Group-III: CRF patients on hemodialysis for more than 6 months (30. We obtained serum samples from patients in the morning after an overnight fast and were analysed for total cholesterol (TC, triglycerides (TGs, HDL, LDL, Lp(a using standard colorimetric assays on fully automated analyzer. VLDL concentration was calculated using Friedewald’s Formula. Results: Among the various parameters tested triglyceride and VLDL levels were significantly higher in group-II and III as compared to controls (p0.05 observed in total cholesterol and LDL levels in between healthy controls and CRF patients with & without hemodialysis. Lp(a levels were significantly higher in group-II and III as compared to controls (p0.05. There was no significant difference (p>0.05 observed between Lp(a levels and lipid profile in male and female patients in control group and in CRF patients with and without hemodialysis. Conclusions: This study demonstrated that CRF patients with and without hemodialysis are at greater risk of development of dyslipidemias, characterized by hypertriglyceridemia, elevated VLDL and Lp(a levels and decreased HDL levels. Total cholesterol and LDL cholesterol levels remain normal or decreased in these patients. Both male and female patients of CRF with and without hemodialysis have dyslipidemias without any discrimination of sex and it is not

    The hypoproliferative anemia in chronic renal failure has been assumed to be the result of decreased erythropoietin (Ep) production by the damaged kidney and of the shortening of erythrocyte survival. However, many in vitro studies suggest that erythropoietic inhibitors in uremic plasma may contribute to the anemia. To determine the in vivo relevance of uremic inhibitors, increasing amounts of Ep as Ep-rich plasma were infused into six uremic sheep, and their erythropoietic responses were compared with those of nine normal sheep receiving similar amounts of Ep-rich plasma. Three sheep were studied in both normal and uremic states. Ep-rich plasma was obtained from phenylhydrazine- and phlebotomy-induced anemic sheep. Stable uremia was created by subtotal nephrectomy. Erythropoiesis was quantitated by reticulocyte response, ferrokinetics (plasma iron turnover and marrow transit time), and by hemoglobin C synthesis. Ep-rich plasma stimulated erythropoiesis similarly in uremic and normal sheep, regardless of the degree of uremia. Nondialyzed uremic sheep responded as well as dialyzed animals. The anemia was corrected in the uremic dialyzed animals. The anemia was corrected in the uremic sheep after 15-40 daily infusions of Ep-rich plasma, the total dosage depending on the severity of the anemia. Polycythemia was induced when the infusions were continued. Reticulocytes, plasma iron turnover, and erythrocyte mass changes increased as the amount of Ep-rich plasma was increased. These dose-response effects, coupled with the identical erythropoietic response in normal and uremic sheep given the same amount of Ep-rich plasma, imply that there are no physiologically significant erythropoietic inhibitors in uremia.

    Chronic renal failure (CRF) is associated with an increased bioavailability of drugs by a poorly understood mechanism. One hypothesis is a reduction in the elimination of drugs by the intestine, i.e., drug elimination mediated by protein membrane transporters such as P-glycoprotein (Pgp) and multidrug-resistance-related protein (MRP) 2. The present study aimed to investigate the repercussions of CRF on intestinal transporters involved in drug absorption [organic anion-transportingpolypeptide (Oatp)] and those implicated in drug extrusion (Pgp and MRP2). Pgp, MRP2, MRP3, Oatp2, and Oatp3 protein expression and Pgp, MRP2, and Oatp3 mRNA expression were assessed in the intestine of CRF (induced by five-sixth nephrectomy) and control rats. Pgp and MRP2 activities were measured using the everted gut technique. Rat enterocytes and Caco-2 cells were incubated with sera from control and CRF rats to characterize the mechanism of transporters' down-regulation. Protein expression of Pgp, MRP2, and MRP3 were reduced by more than 40% (p CRF rats, whereas Oatp2 and Oatp3 expression remained unchanged. There was no difference in the mRNA levels assessed by real-time polymerase chain reaction. Pgp and MRP2 activities were decreased by 30 and 25%, respectively, in CRF rats compared with control (p CRF in rats is associated with a decrease in intestinal Pgp and MRP2 protein expression and function secondarily to serum uremic factors. This reduction could explain the increased bioavailability of drugs in CRF.

The hospitalization time found to be shortening with increasing hemoglobin, hematocrit, calcium and albumin levels; and lengthens with increased urea and creatinine.Conclusion: The history of previous gastrointestinal bleeding and detection of pathological findings in endoscopy were more frequent in patients with CRF. Gastrointestinal bleeding risk did not reduce using by gastric protection against acetylsalicylic acid and other non-steroidal antiinflammatory drugs. Also, low albumin levels and secondary hiperparathyroidism in these patients may be risky for gastrointestinal bleeding. J Clin Exp Invest 2011;2(2:207-13

    Chronic kidney disease (CKD) is associated with the reduction of haemoglobin concentration and a variety of biochemical abnormalities including changes in serum concentration of sodium, potassium, calcium, phosphate, bicarbonate, and hydrogen ions. However, data concerning epidemiology of these abnormalities are rare and incomplete, especially among subjects with mild to moderate CKD. Patients with a serum creatinine concentration > 110 micromol/l hospitalized in the Department of Nephrology, Endocrinology and Metabolic Diseases Medical University of Silesia from 1998 to 2002 were analyzed. Patients with acute renal failure or chronic renal failure treated with renal replacement therapy were excluded from this study. A total of 653 patients (262F and 391M) were divided into 9 subgroups differing from each other by progressive decline of glomerular filtration rate (GFR). A statistically significant decrease in haemoglobin concentration and increase in the prevalence of anaemia were found in patients with GFR 50 ml/min, Hb concentration 4.44 mmol2/12) was noticed almost exclusively in patients with GFR< 30 ml/min. A decompensated metabolic acidosis was observed in 29.8% of patients with GFR <30 ml/min. Anaemia is an early symptom of chronic kidney disease preceding disturbances of calcium, phosphate and hydrogen ions metabolism. These abnormalities seem to be of therapeutic relevance.

    A diabetic patient with chronic renal failure who developed recurrent and prolonged episodes of hypoglycemia associated with use of sulfonylurea agent is presented here. This patient was hospitalized with neuroglycopenic symptoms of hypoglycemia that persisted in spite of large doses of parenteral glucose replacement. On administration of somatostatin analogue octreotide, hypoglycemia resolved and, blood glucose levels were maintained even after cessation of parenteral glucose. The patient received 2 subcutaneous doses of octreotide 12 hours apart, and made a complete recovery. Our experience suggests that use of octerotide to treat refractory or prolonged sulfonylurea-included hypoglycemia in renal failure patients is safe and effective; large prospective studies would be needed to validate these findings.

    The overall incidence of amiodarone-induced thyroid dysfunction ranges from 2% to 24%. One third to half of patients with hypothyroidism have anemia due to some decrease in normal red blood cell mass and erythropoietin (EPO) resistance. Therefore, for patients with chronic renal disease under medication with amiodarone, early regular thyroid function test should be checked in order to avoid amiodarone-induced hypothyroidism and EPO-resistant anemia. If amiodarone-induced hypothyroidism and EP...

    Full Text Available Durante la insuficiencia renal crónica ocurren cambios metabólicos, bioquímicos y hormonales que suelen ir acompañados frecuentemente de estados de malnutrición. En pacientes en prediálisis, conocer el estado nutricional en vitaminas hidrosolubles como la tiamina, riboflavina, piridoxina, cianocobalamaina y ácido fólico cobra cada vez más importancia ya que algunas de las manifestaciones de la insuficiencia renal crónica podrían deberse a la deficiencia de algunas de estas vitaminas hidrosolubles. Las rutas metabólicas en las que participan la mayoría de ellas se encuentran interrelacionadas y resulta complejo comprender de qué manera afecta individualmente la deficiencia de cada vitamina a la patología renal. Este trabajo trata de revisar no sólo este aspecto, sino también el estatus en estas vitaminas hidrosolubles que diferentes autores han encontrado en grupos de pacientes en prediálisis. Por otra parte se aborda la problemática de la elevada prevalencia de hiperhomocisteinemia en la insuficiencia renal crónica como principal factor de riesgo de mortalidad por patologías cardiovasculares, así como la implicación de las vitaminas objeto de esta revisión en el metabolismo de la homocisteína y por consiguiente en los niveles plasmáticos de dicho metabolito en pacientes en prediálisis.Metabolic, biochemical, and hormonal changes occur in chronic renal failure usually associated with hyponutrition states. In predialysis patients, knowing the nutritional state about water-soluble vitamins such as thiamine, riboflavin, pyridoxine, cianocobalamine, and folic acid is becoming more and more important since some of the manifestations of chronic renal failure may be due to the deficiency of some of these water-soluble vitamins. The metabolic pathways in which most of these vitamins participate are interrelated and it is difficult to understand how the individual deficits of each vitamin affect renal pathology.

    To determine whether the apparent benefit of revascularization of renal artery stenosis for "flash" pulmonary oedema extends to heart failure patients without a history of prior acute pulmonary oedema. A prospective study of patients with renal artery stenosis and heart failure at a single centre between 1(st) January 1995 and 31(st) December 2010. Patients were divided into those with and without previous acute pulmonary oedema / decompensation. Survival analysis compared revascularization versus medical therapy in each group using Cox regression adjusted for age, eGFR, blood pressure, and co-morbidities. There were 152 patients: 59% male, 36% diabetic, age 70 ± 9 years, eGFR 29 ± 17 mL/min/1.73 m(2) . 52 had experienced previous acute pulmonary oedema (34%), whereas 100 had no previous acute pulmonary oedema (66%). The revascularization rate was 31% in both groups. For heart failure without previous acute pulmonary oedema, the hazard ratio for death after revascularization compared to medical therapy was 0.76 (0.58-0.99, p = 0.04). In heart failure with previous acute pulmonary enema, the hazard ratio was 0.73 (0.44-1.21, p = 0.22). For those without previous acute pulmonary oedema, the hazard ratio for heart failure hospitalization after revascularization compared to medical therapy was 1.00 (0.17-6.05, p = 1.00). In those with previous acute pulmonary oedema, it was 0.51 (0.08-3.30, p = 0.48). The benefit of revascularization in heart failure may extend beyond the current indication of acute pulmonary oedema. However, findings derive from an observational study. This article is protected by copyright. All rights reserved.

    Ulnar and peroneal motor nerve conduction volocities (MNCVs) were measured in 47 children in a dialysis-transplantation program. Mean peroneal MNCV was significantly decreased from normal in children with mild renal failure (serum creatinine concentration, 1.5 to 2.9 mg/dl), whereas ulnar MNCV was significantly decreased only when the serum creatinine value was at least 9 mg/dl. Both ulnar and peroneal MNCVs remained unchanged during long-term hemodialysis or peritoneal dialysis; however, after individual dialyses ulnar MNCV increased. After renal transplantation ulnar MNCV returned to normal within a year and peroneal MNCV within 3 years. Before dialysis was required and during long-term dialysis most plasma magnesium values were elevated; ionized calcium activity was decreased in about 50% of determinations. After transplantation and the concentration of divalent cations rapidly returned to normal. These children differed from adults studied in that (a) there was no correlation between severity of renal failure and MNCV, (b) long-term dialysis did not improve MNCV and (c) peroneal velocities did not recover for 3 years after transplantation.

    1. The effects of tenoxicam on renal function were studied in 10 patients with chronic renal failure (creatinine clearance 46.7 +/- 11.9 ml min-1 1.73 m-2) and eight healthy volunteers. A parallel treatment control group of eight healthy volunteers received placebo. Tenoxicam was given orally in a dose of 40 mg daily for 2 days followed by 20 mg daily for a further 8 days. Renal function was assessed by measurement of the renal clearances of inulin and p-aminohippurate (PAH) using the single injection technique before and during administration of tenoxicam. 2. In the healthy volunteers there were no changes in glomerular filtration rate, effective renal plasma flow, or the urinary excretion of N-acetylglucosaminidase and beta 2-microglobulin on the 3rd and 10th days of treatment with tenoxicam. The mean urinary excretion of prostaglandins E2 and 6-keto F1 alpha decreased during treatment but there was great individual variation and the differences were not statistically significant. Tenoxicam had no effect on the half-life, clearance, volume of distribution or urinary recovery of inulin and PAH. 3. There was no significant change in the clearance of inulin and creatinine after treatment with tenoxicam for 10 days in the patients with chronic renal failure. However, in this group there was a significant increase in plasma creatinine on the 3rd and 6th days with a return to pretreatment levels by the 10th day. The administration of tenoxicam for 10 days was associated with a small but significant increase in the plasma half-life and volume of distribution of inulin.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1958445

    Chronic renal failure is a global public health problem. In developed countries, this disease occurs mainly in the elderly, but in Africa it rather affects active young subjects. This disease need for expensive treatments in a low income country, because of its costs. Our aim is to describe the epidemiology of new cases of chronic renal failure in Madagascar. This is a retrospective, descriptive study of 239 patients with chronic renal failure over a 3 year period, starting from 1 January 2007 to 31 December 2009, in the Department of Internal Medicine and Nephrology at University Hospital of Antananarivo. The incidence was 8.51% among patients hospitalized in the Department. The average age of patients was 45.4 years with extremes of 16 and 82 years and a sex ratio 1,46. The main antecedent was arterial hypertension (59.8%). Chronic renal failure was terminal in 75.31% of the cases (n=180). The causes of chronic renal failure were dominated by chronic glomerulonephritis (40.1%), nephroangiosclerosis (35.5%). Hemodialysis was performed in 3 patients (1.26%), no patient was scheduled for a renal transplantation. Mortality rate in the Department was 28.87%. Chronic renal failure is a debilitating disease with a dreadful prognosis which affects young patients in Madagascar. Its treatment remains inaccessible to the majority of patients. The focus must be mainly on prevention, especially on early effective management of infections, arterial hypertension and diabetes to reduce its negative impacts on the community and public health. The project on renal transplantation: living donor, effective and less expensive treatment compared to hemodialysis could also be a good solution for these Malagasy young subjects.

    Full Text Available Background/Aim. Cardiovascular morbidity and mortality are markedly increased in chronic renal failure (CRF. The aim of this study was to evaluate lipid parameters and bioindices in patients with different stages of CRF. Methods. In 46 hemodialysed (HD, 50 CRF patients with II, III and IV stage of CRF (non-HD and 48 control subjects triglycerides (TG, total cholesterol (C, HDL-C, urea, creatinine, creatinuria (standard biochemical methods, apolipoprotein (apo AI, apo B, lipoprotein(a, cystatin C (immunoturbidimetric method were evaluated, and LDL-C, non-HDL-C, LDLC/ HDL-C, non-HDL-/HDL-C, TG/HDL-C, and new bioindices, LTI (lipid tetrad index, logLTI, LPI (lipid pentad index, logLPI, AIP (atherogenic index of plasma, and creatinine clearance were calculated. Results. There were significant differences in the levels of TG, HDL-C, LDL-C, non- HDL-C, total C and apo A-I between the HD and non-HD patients, and the HD patients and the controls. LTI and LPI were significantly higher in the HD and non-HD patients compared to the controls (p < 0.05, without a good separation by the Box-Whisker plots. The values of TG/HDL-C ratio and AIP were significantly higher in the HD and non- HD-patients compared to the controls (p < 0.05, and significantly higher in the HD compared to non-HD patients (p < 0.05. AIP > 0.11 was found in 71.7% of the HD, 56% of non-HD and 31.3% of the controls. Conclusion. Among lipid parameters and indices, AIP and TG/HDL-C ratio are most suitable for evaluation of lipid disturbances in different stages of CRF. In addition to, non-HDL-/HDL-C, and apoB/A-I ratios, apo A-I, HDL-C and TG are important markers in HD patients. Non-HDL-C is not a suitable marker. LTI and LPI need to be further investigated.

    Full Text Available Aims and Objective: The aim of the study was to evaluate hearing threshold and the severity of hearing loss at different frequencies (250Hz, 500Hz, 1000Hz, 2000Hz, 3000Hz, 4000Hz, 6000Hz, and 8000Hz in patients of chronic renal failure (CRF, and to analyze the role of duration of disease on hearing threshold in patients of CRF. Materials and Methods: Fifty two patients of CRF were evaluated in Nephrology unit and ENT OPD. Cases with middle ear involvement were not included in the study. Pure tone audiometry was done in all cases to establish hearing threshold at different frequencies. Cases with hearing loss were classified according to the severity of hearing loss. In patients with sensorineural hearing loss, mean hearing threshold was calculated. Cases were classified in two groups on the basis of duration of disease (less than two years and more than two years and the mean hearing thresholds were calculated. The significant differences between the mean hearing thresholds of these two groups were assessed using student′s t test for unequal samples. Results : A total of 52 patients (28 males and 24 females were included in the study. Majority of the patients were in 21 to 40 year age group (mean age 36.84 years. Of the 104 ears, 76 ears (73.07% had sensorineural hearing loss and 28 ears (26.93% had normal hearing. Majority of the ears with hearing loss had mild (44.73% or moderate (42.11% sensorineural hearing loss. Mean hearing threshold was higher at low frequencies and high frequencies with a relative sparing of mid frequencies. Comparison of the mean hearing threshold in patients of Group I (duration of disease less than two years - 42 ears and Group II (duration of disease more than two years - 34 ears showed a statistically significant difference (P<0.05 in mean hearing threshold at 250 Hz. Conclusion: Hearing loss is present in majority of the patients of CRF. Most of the cases have mild to moderate sensorineural hearing loss. Hearing

    Full Text Available Background/Aims: Epidemiological evidence indicates that patients with chronic kidney diseases have increased susceptibility to adverse outcomes related to long-term exposure to particulate air pollution. However, mechanisms underlying these effects are not fully understood. Methods: Presently, we assessed the effect of prolonged exposure to diesel exhaust particles (DEP on chronic renal failure induced by adenine (0.25% w/w in feed for 4 weeks, which is known to involve inflammation and oxidative stress. DEP (0.5m/kg was intratracheally (i.t. instilled every 4th day for 4 weeks (7 i.t. instillation. Four days following the last exposure to either DEP or saline (control, various renal endpoints were measured. Results: While body weight was decreased, kidney weight increased in DEP+adenine versus saline+adenine or DEP. Water intake, urine volume, relative kidney weight were significantly increased in adenine+DEP versus DEP and adenine+saline versus saline. Plasma creatinine and urea increased and creatinine clearance decreased in adenine+DEP versus DEP and adenine+saline versus saline. Tumor necrosis factor α, lipid peroxidation and reactive oxygen species were significantly increased in adenine+DEP compared with either DEP or adenine+saline. The antioxidant calase was significantly decreased in adenine+DEP compared with either adenine+saline or DEP. Notably, renal DNA damage was significantly potentiated in adenine+DEP compared with either adenine+saline or DEP. Similarly, systolic blood pressure was increased in adenine+DEP versus adenine+saline or DEP, and in DEP versus saline. Histological evaluation revealed more collagen deposition, higher number of necrotic cell counts and dilated tubules, cast formation and collapsing glomeruli in adenine+DEP versus adenine+saline or DEP. Conclusion: Prolonged pulmonary exposure to diesel exhaust particles worsen renal oxidative stress, inflammation and DNA damage in mice with adenine-induced chronic

    2006-12-01

    The purpose of this review was to examine the impact of varying degrees of renal insufficiency on pregnancy outcome in women with chronic renal disease. Our search of the literature did not reveal any randomized clinical trials or meta-analyses. The available information is derived from opinion, reviews, retrospective series, and limited observational series. It appears that chronic renal disease in pregnancy is uncommon, occurring in 0.03-0.12% of all pregnancies from two U.S. population-based and registry studies. Maternal complications associated with chronic renal disease include preeclampsia, worsening renal function, preterm delivery, anemia, chronic hypertension, and cesarean delivery. The live birth rate in women with chronic renal disease ranges between 64% and 98% depending on the severity of renal insufficiency and presence of hypertension. Significant proteinuria may be an indicator of underlying renal insufficiency. Management of pregnant women with underlying renal disease should ideally entail a multidisciplinary approach at a tertiary center and include a maternal-fetal medicine specialist and a nephrologist. Such women should receive counseling regarding the pregnancy outcomes in association with maternal chronic renal disease and the effect of pregnancy on renal function, especially within the ensuing 5 years postpartum. These women will require frequent visits and monitoring of renal function during pregnancy. Women whose renal disease is further complicated by hypertension should be counseled regarding the increased risk of adverse outcome and need for blood pressure control. Some antihypertensives, especially angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers, should be avoided during pregnancy, if possible, because of the potential for both teratogenic (hypocalvaria) and fetal effects (renal failure, oliguria, and demise).

Várias pesquisas mostram uma maior peroxidação lipídica em eritrócitos e outras células do sangue com implicações importantes na morbidade destes pacientes, principalmente por doenças cardiovasculares. Os níveis de antioxidantes enzimáticos como a glutationa peroxidase, superóxido dismutase e catalase estão reduzidos, bem como os dos elementos traço (Selênio, Zinco. A diminuição das defesas antioxidantes permite o aumento da formação de espécies reativas de oxigênio, o que caracteriza a condição de estresse oxidativo. Em decorrência disto, ocorrem lesões oxidativas que podem alterar a fluidez da membrana dos eritrócitos, contribuindo para a hemólise e piora da anemia, além de causar a oxidação das lipoproteínas de baixa densidade do colesterol, a qual tem um papel importante na patogênese da aterosclerose, que ocorre freqüentemente nos pacientes com insuficiência renal crônica. O objetivo deste trabalho é discutir a relação da peroxidação lipídica e da diminuição das defesas antioxidantes do organismo como fatores importantes na patogênese da insuficiência renal crônica e suas complicações.Evidence suggests an imbalance between antioxidant and oxidant activities and a hyperproduction of free radicals in patients with chronic renal failure. Researches have observed increased levels of plasma and erythrocyte lipid peroxidation and it has recently been implicated as a causative factor of cardiovascular diseases. Antioxidants, including glutathione peroxidase, superoxide dismutase, catalase and trace elements (Selenium, Zinc, are decreased in chronic renal failure. This may cause deterioration of antioxidant defense of red cells contributing to more active red cell destruction, causing anemia in uremia and peroxidation of low density

Results: Ninety percent of patients were in vitamin D deficiency/insufficiency; and only 4 patients (10.0% reached 25OHD levels above 75nmol/L. The median 25OHD level was 31.15nmol/L (interquartile range: 16.67-48.33nmol/L.Tendency of worse vitamin D status in women than in men was observed. Higher 25OHD levels were found in pre-dialysis patients (median 44.81nmol/L, 25%-75% percentile 16.24-52.21nmol/L and lower in HD (median 31.15nmol/L, 25%-75% percentile 13.04-64.45nmol/L and PD patients (median 33.38nmol/L, 25%-75% percentile 23.15-48.49nmol/L, but the difference did not reach statistical significance. Better vitamin D status was found in the PD group of patients receiving vitamin D preparations (p<0.05. Conclusions: 25OHD deficiency/insufficiency is prevalent in renal failure patients with or without renal replacement therapy. It seems that vitamin D therapy improves the vitamin D status of PD patients. Further larger studies are needed to clarify the effect of specific type vitamin D therapy on serum 25OHD levels and clinical outcome in different groups of CKD patients.

    To assess the prevalence of kidney failure in patients from a primary care centre in a basic healthcare district with laboratory availability allowing serum creatinine measurements. An observational descriptive cross-sectional study. A basic healthcare district serving 23,807 people aged ≥ 18 years. Prevalence of kidney failure among 17,240 patients having at least one laboratory measurement available was 8.5% (mean age 77.6 ± 12.05 years). In 33.2% of such patients an occult kidney failure was found (98.8% were women). Prevalence of chronic kidney failure among 10,011 patients having at least 2 laboratory measurements available (≥ 3 months apart) was 5.5% with mean age being 80.1 ± 10.0 years (most severely affected patients were those aged 75 to 84); 59.7% were men and 76.3% of cases were in stage 3. An occult kidney failure was found in 5.3% of patients with women being 86.2% of them (a glomerular filtration rate<60 ml/min was estimated for plasma creatinine levels of 0.9 mg/dl or higher). Comparison of present findings to those previously reported demonstrates the need for further studies on the prevalence of overall (chronic and acute) kidney failure in Spain in order to estimate the real scope of the disease. Primary care physicians play a critical role in disease detection, therapy, control and recording (in medical records). MDRD equation is useful and practical to estimate glomerular filtration rate.

    Anemia and chronic renal failure (CRF) are frequent comorbidities in patients with heart failure (HF), and they have been reported to be associated with increased mortality and hospitalization rates. HF, anemia, and CRF have been reported to interact with each other forming a vicious cycle termed cardio-renal-anemia syndrome. The aim of the present study was to evaluate the association of HF, anemia, and CRF using data from the large-scale"Heart Failure Prevalence and Predictors in Turkey (HAPPY)" study. Among the HAPPY cohort, 3,369 subjects who had either left ventricular dysfunction (LVD) or normal left ventricular function on echocardiography or normal serum NT-proBNP levels were included in this analysis. The prevalence of anemia and CRF was significantly higher in patients with LVD compared with subjects with normal ventricular function (20.7 % vs. 4.0 % and 19.0 % vs. 3.7 %, respectively; p anemia, and CRF demonstrated that each one was an independent predictor for the presence of the others. These findings point to the presence of cardio-renal-anemia syndrome and the necessity of treating these comorbidities in patients with HF.

    2016-01-01

    Renal failure during pregnancy affects both mother and fetus, and may be related to preexisting disease or develop secondary to diseases of pregnancy. Causes include hypovolemia, sepsis, shock, preeclampsia, thrombotic microangiopathies, and renal obstruction. Treatment focuses on supportive measures, while pharmacologic treatment is viewed as second-line therapy, and is more useful in mitigating harmful effects than treating the underlying cause. When supportive measures and pharmacotherapy prove inadequate, dialysis may be required, with the goal being to prolong pregnancy until delivery is feasible. Outcomes and recommendations depend primarily on the underlying cause.

    Background Protein carbamylation, a post-translational modification promoted during uremia and catalyzed by myeloperoxidase (MPO) at sites of inflammation, is linked to altered protein structure, vascular dysfunction, and poor prognosis. We examine the relationship between plasma protein-bound homocitrulline (PBHCit) levels, a marker of protein lysine residue carbamylation, with cardio-renal function and long-term outcomes in chronic systolic heart failure. Methods and Results In 115 patients with chronic systolic HF (LVEF≤35%), we measured plasma PBHCit by quantitative mass spectrometry and performed comprehensive echocardiography with assessment of cardiac structure and performance. Adverse long-term events (death, cardiac transplant) were tracked for 5 years. In our study cohort, the median PBHCit level was 87 [IQR: 59, 128] μmol/mol Lysine. Higher plasma PBHcit levels were associated with poorer renal function (eGFR Spearman’s r= −0.37, p0.10 for each). Furthermore, elevated plasma PBHCit levels were not related to indices of cardiac structure or function (p>0.10 for all examined) except modestly with increased right atrial volume index (RAVi; r=0.31, p=0.002). PBHCit levels predicted adverse long-term events (Hazard ratio [HR]: 1.8, 95% CI 1.3– 2.6, p<0.001), including following adjustment for age, eGFR, MPO and NT-proBNP (HR: 1.9, 95% CI: 1.2–3.1, p=0.006). Conclusions In chronic systolic HF, protein carbamylation is associated with poorer renal but not cardiac function, and portends poorer long-term adverse clinical outcomes even when adjusted for cardio-renal indices of adverse prognosis.

    In spite of recent advances in perioperative management, the risk of neurosurgical intervention for patients with chronic renal failure is still considered too high. In this study, coil embolization for incidental aneurysms in such patients is demonstrated in reference to midterm results. A 42-year-old woman with a history of hemodialisis for 7 years presented with subcortical hemorrhage in her right frontal lobe. The magnetic resonance angiography (MRA) demonstrated a distal anterior cerebral artery aneurysm, but it was considered to be unrelated to the hemorrhage. Two and a half months after the hemorrhage the aneurysm was embolized with interlocking detachable coils. Thirty months after embolization, the angiogram revealed the coil compaction and the recanalization of the aneurysm neck. However, 54 months after embolization, the figure of the embolized aneurysm and neck remnant was the same as the previous findings. A 69-year-old woman with a history of hemodialisis for 5 years suddenly experienced left hemiparesis. Computed tomography revealed cerebral infarction in the right frontoparietal white matter. In addition, a left middle cerebral artery aneurysm was unexpectedly found on the MRA. Five months after the onset of the attack, the aneurysm was embolized with a Guglielmi detachable coli. An angiogram obtained 24 months after the embolization showed the aneurysm to be almost completely obliterated. In considering the therapeutic risks and benefits for incidental aneurysms of patients with chronic renal failure, intra-vascular surgery could be recommended as a less invasive treatment.

    Cardiovascular morbidity and mortality are highly prevalent among patients with chronic renal failure (CRF). Endothelial dysfunction is regarded as the initial reversible step in the development of atherosclerosis and has been demonstrated in all stages of renal failure. Non-invasive techniques to assess endothelial function have been recently developed and have been proven to predict future mortality in adults. We aimed to assess endothelial function in children with stage 4 chronic kidney disease (CKD 4) on conservative treatment, using a-non invasive, high-resolution, ultrasound Doppler study of the brachial artery flow, correlating it with other clinical and laboratory parameters. This study included 34 children with CKD 4 on conservative treatment who were compared with 30 healthy controls. Flow-mediated dilatation (FMD), nitroglycerin-mediated dilatation (NTG-MD) and FMD/NTG-MD ratio were estimated. FMD was abnormal (< 5%) in 24 patients (71%). FMD and FMD/NTG-MD ratio were significantly lower in patients than in controls (P = 0.001 and P = 0.01, respectively). FMD correlated positively with serum calcium and negatively with alkaline phosphatase. We concluded that endothelial dysfunction is present in children with CKD 4 on conservative treatment and may reflect increased atherogenic and thrombogenic properties of the endothelium, contributing to subsequent adverse cardiovascular outcome.

    Coronary artery bypass grafting for patients with ischemic heart disease and hypothyroidism contains many controversies, and chronic renal failure causes perioperative water-electrolyte balance disorders. We experienced a case of unstable angina pectoris combined with hypothyroidism and chronic renal failure successfully treated by off-pump coronary artery bypass grafting (OPCAB). A 68-year-old man with a history of hypothyroidism and chronic renal failure was hospitalized with chest pain. Cardiac catheterisation revealed a 90% stenosis of segment 3, 11 and right ventricular (RV) branch, 75% stenosis of segment 6 and 50% stenosis of segment 5. His thyroid function was normal with orally administered levothyroxine. OPCAB was performed safely with hemodialysis until a day before operation and hemofiltration from a day after operation, and postoperative course was uneventful.

    Berger disease is described as a glomerulonephritis by anti-IgA and anti-IgG immune complexes and it has become the most common form of glomerulonephritis, affecting up to 1,3% of the population, most often affecting young adult males. Berger disease etiopathogenesis is still unknown, being well recognized its temporal associations with bacterial and viral infections, as well with genetic factors which lead some authors to suggest the existence of a founder effect. Characteristically IgA nephropathy presents intermittent macroscopic hematuria following mucosal infections, nonnephrotic proteinuria and persistent microscopic hematuria. A renal biopsy should be performed in patients in whom this diagnosis is suspected, particularly if there is persistent proteinuria. IgA nephropathy was initially considered a benign disease, but long term follow up studies have shown the course to be slowly progressive with up to 50% of the patients developing terminal renal failure. The authors propose themselves a therapeutic algoritm, as well as clinical indicators of evolutive course.

    Treatment of hypertension in patients with chronic renal failure has been shown to postpone the decline in renal function. Treatment with an ACE inhibitor has been shown to be superior to conventional antihypertensive treatment, but it is not known how an ACE inhibitor compares to treatment...... with a calcium channel blocker or to treatment with a combination of these drugs. The aim of the study was to evaluate the rate of decline in GFR in patients with chronic renal failure and hypertension treated with isradipine and spirapril as monotherapy and in combination....

    In order to elucidate brain oxygen metabolism in uremic patients, the regional cerebral blood flow (rCBF), oxygen extraction (rOEF) and oxygen metabolism (rCMRO{sub 2}) were measured by positron emission tomography (PET) in both 10 hemodialysis patients (HD: male [m]/female [f]=2/8, age of 49{+-}3 [SEM] years old, HD duration of 113{+-}26 months) and 13 pre-dialysis renal failure patients (CRF: m/f=10/3, age of 61{+-}2 years old, serum creatinine (SCr) of 6.3{+-}1.0 mg/dl). Data were compared with 20 non-uremic subjects (Control: m/f=7/13, age of 62{+-}2 years old, SCr of 0.9{+-}0.1 mg/dl). They had no neurological abnormalities, congestive heart failure, history of cerebrovascular accident, diabetes mellitus, or symptomatic brain lesion on magnetic resonance imaging. The age of HD was significantly younger than the other groups (p<0.02) and the hemoglobin (Hb) levels in both HD (10.5{+-}0.5 g/dl) and CRF (9.8{+-}0.9) were significantly lower than that in Control (13.3{+-}0.3) (p<0.02). In the hemisphere, rCMRO{sub 2} in both HD (1.82{+-}0.10 ml/min/100 g) and CRF (1.95{+-}0.09) showed significantly lower values as compared to Control (2.23{+-}0.05) (p<0.01, respectively). Hemispheric rCBF in HD (35.6{+-}2.1 ml/100 g/min) and in CRF (36.1{+-}2.1) were not different from that in Control (31.8{+-}1.4). Hemispheric rOEF in CRF (45.7{+-}1.6%) was significantly higher than that in Control (40.5{+-}1.2%) (p<0.02), but that in HD (43.7{+-}1.9%) did not increase significantly. These tendencies were similar in all regions of interest, especially in the cerebral cortices, but not in the cerebellum. All PET parameters in the frontal cortices tended to show the lowest value in renal failure patients. For all HD patients, rCBF in both the frontal cortex and the white matter correlated inversely with HD duration (frontal cortex: r=-0.649, p<0.05; white matter: r=-0.706, p<0.02). Based on these data, it is concluded that brain oxygen metabolism is depressed in renal failure

    Endothelin-1 (ET-1) and atrial natriuretic peptide (ANP) play important roles in the regulation of body fluid balance in congestive heart failure (CHF). Renal production of ET-1 increases in CHF and it is a significant independent predictor of sodium excretion. ANP inhibits the ET system through cGMP, a second messenger of ANP. However, in severe CHF, plasma cGMP levels reached a plateau despite the activation of ANP secretion. Thus, ANP does not seem to sufficiently oppose exaggerated ET-1 actions in severe CHF, partially due to the accelerated degradation of cGMP, through phosphodiesterase type 5 (PDE5). We examined the chronic effects of a PDE5 inhibitor, T-1032 (1 mg/kg per day, n=5), on renal function and renal production of ET-1 in dogs with CHF induced by rapid ventricular pacing (270 beats/min). Vehicle dogs were given a placebo (n=5) and normal dogs (n=5) served as normal controls without pacing. In this experimentally produced CHF, plasma levels of ET-1, ANP and cGMP were elevated and renal production of cGMP was increased compared with the normal group, associated with increases in renal expression of preproET-1 mRNA and the number of ET-1-positive cells in glomeruli. In the T-1032 group, systemic and renal production of cGMP were further increased compared with the vehicle group despite no significant difference in plasma ANP levels between the two groups. Subsequently, the agent significantly improved urine flow rate, sodium excretion rate and glomerular filtration rate (GFR) associated with reductions in renal expression of preproET-1 mRNA and the number of ET-1-positive cells compared with the vehicle group. Moreover, there was a significant negative correlation between the number of ET-1-positive cells and GFR (r=-0.802 and Prenal ANP and ET-1 through the cGMP pathway, subsequently preventing renal dysfunction during the progression of CHF.

    Star fruit (Averrhoa carambola) is a popular tropical fruit that is usually consumed as fresh fruit or fruit juice. Consumption of star fruit by patients with chronic renal failure can lead to neurologic symptoms. The present report describes the clinical course, management, and outcome of a patient with chronic renal failure admitted to an intensive care unit after ingestion of star fruit juice 2 days before hospital admission. A case of nausea, vomiting, intractable hiccups, and severe encephalopathy along with mental confusion, disorientation, agitation, and seizures in a 53-year-old woman is presented. The patient's ventilatory pattern worsened, with development of dyspnea and tachypnea, which resulted in her transfer to an intensive care unit. Although hemodialysis was performed and the septic shock was adequately treated, the patient died on the fifth day after hospital admission. The susceptibility of patients with chronic renal failure to star fruit and the severity of intoxication are poorly known by intensivists. This case demonstrates that star fruit consumption should be considered as a cause of rapid deterioration in the renal function of patients with underlying chronic renal failure, potentially resulting in a fatal outcome.

    Full Text Available Background: Helicobacter pylori (H.pylori plays an important role in gastroduodenal disease. However, there are few data concerning the epidemiology of H.pylori in patients with chronic renal failure and on hemodialysis (HD treatment. Aim of the study: This study is aimed to determine the epidemiology of H.pylori infection in patients with end stage renal disease (ESRD on Hemodialysis (HD. Patients and Methods: Ninety-six patients with dyspeptic complaints were included in the study. They were divided into two groups; group one consisted of 46 patients with ESRD on HD and group two (control of 50 patients without renal disease. All patients were subjected to upper gastrointestinal endoscopies, and gastric biopsies were obtained for histological evidence of H. pylori infection. Results: The mean age of both groups was similar. The prevalence of H.pylori among the two groups was not significantly different (45.7%Vs48%=p>0.05. The prevalence of duodenal ulcers was significantly higher in H.pylori positive than in H.pylori negative ESRD patients (p< 0.05. GERD was significantly lower in H.pylori positive patients in both groups (p< 0.001 and p< 0.01 respectively. Conclusion: This study showed a similar prevalence of H.pylori infection in both groups. H.pylori infection in patients with ESRD is probably associated with increased risk of gastroduodenal lesions

    AIM: To investigate the role of wireless capsule endoscopy (WCE) in detection of small bowel (SB) pathology in patients with chronic renal failure (CRF) and obscure bleeding.METHODS: Consecutive CRF patients with obscure bleeding were prospectively studied. Patients with normal renal function and obscure bleeding, investigated during the same period with WCE, were used for the interpretation of results.RESULTS: Seventeen CRF patients (11 overt, 6 occult bleeding) and 51 patients (33 overt, 18 occult bleeding) with normal renal function were enrolled in this study.Positive SB findings were detected in 70.6% of CRF patients and in 41.2% of non-CRF patients (P < 0.05). SB angiodysplasia was identified in 47% of CRF patients and in 17.6% of non-CRF patients. Univariate logistic regression revealed CRF as a significant predictive factor for angiodysplasia (P < 0.05). Therapeutic measures were undertaken in 66% of the patients with the positive findings.CONCLUSION: According to our preliminary results, SB angiodysplasia was found in an increased prevalence among CRF patients with obscure bleeding. WCE is useful in diagnosis of gastrointestinal pathologies and in planning appropriate therapeutic intervention and, therefore, should be included in the work-up of this group of patients.

    Chronic inflammation is increased in patients with chronic kidney disease (CKD) and contributes to cardiovascular morbidity and mortality. Specific immune mechanisms and pathways that drive and maintain chronic inflammation in CKD are not well described. The TAM ligands (Gas6 and protein S) and receptors (Axl and Mer) have been recently recognized as playing a prominent role in immune regulation. The receptors exist in both soluble and cell-bound forms; the soluble receptors (sAxl and sMer) are believed to compete with the bound receptors and thus inhibit their function. In this study, we determined the expression of cell-bound and soluble TAM proteins in patients with CKD. CKD patients had significantly lower expression of Mer in monocytes, yet increased expression of soluble TAM receptors sAxl and sMer in plasma compared to controls. The metalloproteinase ADAM 17, responsible for cleavage of Mer to its soluble form, was increased in patient monocytes. Elevated levels of soluble TAM receptors were more evident in patients with progressive renal failure. These observations suggest that functional deficiency of TAM receptor-mediated regulation of inflammation may contribute to chronic inflammation in patients with CKD.

    This study aimed at assessing the quality of life (QL) of patients with chronic kidney failure under high efficiency hemodialysis. The Medical Outcomes Study 36 Item Short Form Health Survey (SF36) was applied, and the results were correlated with social-demographic profile, clinical and laboratorial data, Karnofsky's Scale and Depression Cognitive Index (DCI). The sample consisted of 50 patients with an average age of 37 and mean treatment duration of 50.6 months. LQ changes were evidenced by correlations of SF36 scores with social-demographic aspects, clinical data, Karnofsky's Scale, and DCI. It was concluded that the individual use of SF36 may aid the assessment of therapeutic conduct.

    The effects of low-molecular-weight-chitosan (LMWC) on chronic renal failure (CRF) rats induced by adenine were investigated in vivo and in vitro. Chitosan were hydrolyzed using chitosanase at pH 6-7 and 37° for 24 h to obtain LMWC. In vitro, the effect of LMWC on the proliferation of renal tubular epithelial cells (RTEC) showed that it had no cytotoxic effect and could promote cell growth. For the in vivo experiment, chronic renal failure rats induced by adenine were randomly divided into control group, Niaoduqing group, and high-, medium- and low-dose LMWC groups. For each group, we detected serum creatinine (SCR), blood urea nitrogen (BUN), and total superoxide dismutase (T-SOD), glutathione oxidase (GSH-Px) activities of renal tissue, and obtained the ratio of kidney weight/body weight, pathological changes of kidney. The levels of serum SCR, BUN were higher in the adenine-induced rats than those in the control group, indicating that the rat chronic renal failure model worked successfully. The results after treatment showed that LMWC could reduce the SCR and BUN levels and enhance the activities/levels of T-SOD and GSH-PX in kidney compared to control group. Histopathological examination revealed that adenine-induced renal alterations were restored by LMWC at three tested dosages, especially at the low dosage of 100 mg kg-1 d-1.

    Full Text Available AIM: To investigate the correlation between intraocular pressure(IOPchanges pre- and post-hemodialysis(HDand the biometric structure of the anterior chamber in patients of chronic renal failure. METHODS: Fifty-two patients(take right eye as study onewith hemodialysis that were diagnosed with chronic renal failure by nephrology in our hospital from January 2015 to December 2015 were collected. Fifty-two eyes were divided into four groups based on Shaffer classification combined with ultrasound biomicroscopy(UBMand gonioscopy manifestations: wide angle group, narrow angle group, extremely narrow group and close angle group. Venous blood was collected to get plasma colloid osmotic pressure before HD and within 60s after HD. IOP was measured with rebound intraocular pressure gauge in a supine positon approximately 30min before starting HD, 2h after HD begin and approximately 30min after HD ending. Approximately 30min before and after HD, central corneal thickness was measured with corneal endothelial cell counter, central anterior chamber depth and lens thickness were taken by A scan, angle opening distance, trabecular iris angle, iris thickness and ciliary body thickness were measured by UBM. RESULTS: Plasma osmotic pressure reduced after HD, the difference was statistically significant(t=3.04, PF=41.69, PPPF=6.44, PPt=2.61, PCONCLUSION: The influence of hemodialysis on IOP is related to the biometric structure of the anterior chamber. And extremely narrow angle is risk factor of elevated IOP during hemodialysis, narrow angle may be a risk factor. While patients with wide angle is relatively safe. We suggest to take ocular examination as early as possible for patients with hemodialysis, and focus on patients with narrow angle.

In the present study 103 patients were included, 54 (55% men between the age 51,5±15,4 and 49 (45% women between the age 50,3±15,5, who belong to (CRH one of the three medical units of artificial kidney in corresponding hospitals of Athens. The patients fulfills the above mentioned questionnaire, EPQ which contains 84 questions from which 24 for the control of psychotism, 22 for neurotism and 19 questions for the extroversion, 16 for the control of lie intention and the rest included diversion tactics.RESULTS: We concluded that all three scales of personality disorders appeared to be systematically affected in comparison with a group 138 healthy persons of the control group, matched according to their age and sex. In details, we recognized that males patients under the CRH program have been concentrated in a lower area of the scale of neurotism while female patients appeared to be concentrated in a lower area of scale of psychotism. The initial complaint, which provoked the initial disorder and the resultant need of incorporation into CRH program, was contributed to specific types of personality disturbance. Moreover, the patients with vascular complaints appeared with the tense to develop neurotism in a higher degree than patients with glomerulonephritis, whose account scale showed higher reduction. The disorder of neurotism appeared significantly reduced in patients with multicystic disease of the kidney. In the opposite side the disorder of

    Full Text Available Introduction: Chronic renal disease (C.R.D is a pathophysiological process due to progressive and irreversible decrease in number and function of nephrons in the kidney. Anemia is one of the most important complications in CRD patients. Anemia is caused mainly due to diminished production of erythropoietin (EPO, which is treated by weekly injection of the EPO. L-carnitine added to EPO can increase the efficacy of EPO. Methods: Present study, from March 2003 until September 2004 (18 months, evaluates the effects of L-carnitine added to EPO in 30 patients at Shaheed Rahnemon hemodialysis center of Yazd. Each patient was administered one oral table (250 mg of L-carnitine, twice a day along with EPO for 90 days. EPO was in the form of injection 2000 iu/sc after dialysis.(three times per week. One questionnaire was completed for each patient, which included demographic characteristics, type of disease, duration of the hemodialysis, Hb and Hct levels, transferrin saturation and ferritin levels. Hb ,Hct and transferrin saturations were measured on days 1, 45 and 90. Results were analyzed by paired t test and analysis of variance. Results: Results of this study showed that the mean Hb levels and Hct were significantly raised up to 1.1 mg/dl (P.value<0.001 and 2.7% (P.Value<0.001, respectively. In addition, significant decrease of 5.75% in transferrin (P.Value< 0.001 and 121ng/ml in ferritin levels (P.Value< 0.001 was observed. Efficacy of EPO plus L-carnitine was affected only by duration of hemodialysis and not by age, sex or causes of CRD. Conclusion: L-carnitine added to EPO increases the efficacy of EPO after 3 months.

    Full Text Available Background/Aims: Decreased thrombopoiesis has been ascribed a role in the pathogenesis of uremic bleeding in chronic renal failure (CRF. However, serum thrombopoietin (TPO levels are usually elevated in CRF patients, suggesting increased thrombopoiesis. The aim of this study was to determine the thrombopoietic activity in CRF. Methods: Male Sprague-Dawley rats that underwent 5/6 nephrectomy were used as the model of CRF. Age-matched sham-operated rats were used as controls. Single megakaryocytes were isolated from the rat bone marrow, and their size distribution was examined. Megakaryocyte membrane invaginations were monitored by confocal imaging of di-8-ANEPPS staining, and patch clamp whole-cell recordings of membrane capacitance. TPO gene expression was assessed in various tissues. Results: Circulating platelet counts and the number of large megakaryocytes were increased in the bone marrow of CRF rats. Massive di-8-ANEPPS staining and increased membrane capacitance in large megakaryocytes demonstrated increased membrane invaginations. Unaffected Kv1.3-channel currents per cell surface area demonstrated unaltered channel densities. TPO transcription was decreased in the renal cortex but increased in the liver and bone marrow of CRF rats. Conclusion: Increased thrombopoiesis in CRF was thought to be a reactive mechanism to platelet dysfunction. Increased TPO production from the liver and bone marrow compensated for decreased production from damaged kidneys.

    Spontaneous ruptures of the quadriceps tendon are infrequent injuries, it is seen primarily in patients with predisposing diseases such as gout, rheumatoid arthritis and chronic renal failure. A 32-year-old man had a history of end stage renal disease and received regular hemodialysis treatment for more than 5 years. He was admitted in our service for total functional impotence of the right lower limb with knee pain after a common fall two months ago. The radiogram showed a ''patella baja" with suprapatellar calcifications. The ultrasound and MRI showed an aspect of rupture of the quadriceps tendon in its proximal end with retraction of 3 cm. Quadriceps tendon repair was performed with a lengthening plasty, and the result was satisfactory after a serial rehabilitation program. The diagnosis of quadriceps tendon ruptures needs more attention in patients with predisposing diseases. They should not be unknown because the treatment of neglected lesions is more difficult. We insist on the early surgical repair associated with early rehabilitation that can guarantee recovery of good active extension.

    Chronic kidney disease is associated with sympathetic activation and muscle abnormalities, which may contribute to decreased exercise capacity. We investigated the correlation of renal function with peak exercise oxygen consumption (V̇O2) in heart failure (HF) patients. METHODS AND RESULTS: We recruited 2,938 systolic HF patients who underwent clinical, laboratory, echocardiographic and cardiopulmonary exercise testing. The patients were stratified according to estimated glomerular filtration rate (eGFR). Mean follow-up was 3.7 years. The primary outcome was a composite of cardiovascular death and urgent heart transplantation at 3 years. On multivariable regression, eGFR was predictor of peakV̇O2(Pheart rate, B-type natriuretic peptide, hemoglobin, and treatment. After adjusting for significant covariates, the hazard ratio for primary outcome associated with peakV̇O2<12 ml·kg(-1)·min(-1)was 1.75 (95% confidence interval (CI): 1.06-2.91; P=0.0292) in patients with eGFR ≥60, 1.77 (0.87-3.61; P=0.1141) in those with eGFR of 45-59, and 2.72 (1.01-7.37; P=0.0489) in those with eGFR <45 ml·min(-1)·1.73 m(-2). The area under the receiver-operating characteristic curve for peakV̇O2<12 ml·kg(-1)·min(-1)was 0.63 (95% CI: 0.54-0.71), 0.67 (0.56-0.78), and 0.57 (0.47-0.69), respectively. Testing for interaction was not significant. Renal dysfunction is correlated with peakV̇O2. A peakV̇O2cutoff of 12 ml·kg(-1)·min(-1)offers limited prognostic information in HF patients with more severely impaired renal function.

    Increased bone loss has been associated with the development of vascular calcification in patients with chronic renal failure (CRF). In this study, the effect of impaired bone metabolism on aortic calcifications was investigated in uremic rats with or without ovariectomy. CRF was induced by administration of a 0.75% adenine/2.5% protein diet for 4 weeks. In one group, osteoporosis was induced by ovariectomy (CRF-OVX), while the other group underwent a sham-operation instead (CRF). A third group consisted of ovariectomized rats with normal renal function (OVX). At regular time intervals throughout the study, bone status and aortic calcifications were evaluated by in vivo micro-CT. At sacrifice after 6 weeks of CRF, bone histomorphometry was performed and vascular calcification was assessed by bulk calcium analysis and Von Kossa staining. Renal function was significantly impaired in the CRF-OVX and CRF groups. Trabecular bone loss was seen in all groups. In the CRF-OVX and CRF groups, trabecular bone density was restored after adenine withdrawal, which coincided with cortical bone loss and the development of medial calcifications in the aorta. No significant differences with regard to the degree of aortic calcifications were seen between the two CRF groups. Neither cortical bone loss nor calcifications were seen in the OVX group. Cortical bone loss significantly correlated with the severity of vascular calcification in the CRF-OVX and CRF groups, but no associations with trabecular bone changes were found. Cortical rather than trabecular bone loss is associated with the process of calcification in rats with adenine- induced CRF. Copyright © 2011 S. Karger AG, Basel.

    Full Text Available Background: Complementing herbal drugs with conservative modern treatment could improve renal condition in canine chronic renal failure (CRF. Objective: In this study, clinical evaluation of Boerhavia diffusa root extract was carried out in CRF in dogs in comparison with standard enalapril. Materials and Methods: A total of 20 dogs of mixed breeds suffering from CRF from 1 to 2 months were divided into two groups (n = 10 and treated as follows: Group I - Enalapril at 0.5 mg/kg p.o. once daily for 90 days + amoxicillin and cloxacillin at 25 mg/kg i.m. once daily for 1-week; Group II - B. diffusa root extract at 500 mg p.o per dog daily for 90 days. Both groups were maintained on a supportive fluid therapy. The data were analyzed using paired t-test and one-way ANOVA followed by Dunnett's post-hoc test. Results: CRF caused a significant (P < 0.05 increase in systolic and diastolic blood pressure, serum creatinine, urea nitrogen, sodium, potassium, phosphorus, urinary protein, alkaline phosphatase (ALP, and glutamyl transferase (GGT. A significant (P < 0.05 decrease in hemoglobin and total erythrocyte count (TEC was also observed. Nephrosonography revealed indistinct corticomedullary junction, altered renal architecture, hyper-echoic cortex, medulla, and sunken kidneys. Both the treatments significantly (P < 0.05 reduced systolic and diastolic blood pressure by day 30. Serum Creatinine, urea nitrogen, phosphorus, urinary protein, ALP, and GGT showed significant (P < 0.05 reduction by day 60 in both the treatments. However, potassium levels were normalized only by B. diffusa root extract treatment by day 30. Both the treatments failed to show a significant improvement in nephrosonographic picture even after 90 days posttreatment. Conclusions: In conclusion, the efficacy of B. diffusa root extract was comparable to standard enalapril treatment of CRF in dogs.

    Occult hepatitis B (OHB) is characterized by the presence of HBV-DNA in the absence of HBsAg in the serum of patients. Hemodialysis patients are at high risk for hepatitis B virus and there are few data on the prevalence of OHB in this population, mainly in Brazil. Thus, the aim of this study was to determine the prevalence of OHB in patients undergoing hemodialysis. A cross-sectional study was performed, including 301 patients on chronic hemodialysis at two dialysis centers in São Luís (Maranhão), northeast Brazil. Serological tests were performed for HBsAg, anti-HBc, anti-HBs, and anti-HCV using enzyme immunoassays (ELISA); HBV-DNA and HCV-RNA were studied by real-time PCR. The mean age was 49 ± 15 years, and 128 (42%) were female. Serological tests confirmed that all samples were HBsAg negative. Anti-HBc was positive in 114 (38%) patients, anti-HBc and anti-HBs were simultaneously positive in 104 (35%), and anti-HBc alone was positive in 10 (3%). Tests were negative for anti-HBc and anti-HBs in 55 patients (18%). Anti-HBs was the only positive marker in 132 (44%) patients. Anti-HCV was positive in 15 (5%) patients with HCV-RNA present in 14 of them (93%). HBV-DNA was positive in seven cases (2.3%). There was no association of HBV-DNA with age, gender, time on dialysis, previous kidney transplant, or HBV serological pattern, but there was a positive correlation with the presence of anti-HCV (P < 0.001). OHB in chronic renal failure patients on hemodialysis appears to be a relevant finding, suggesting that studying HBV-DNA in this population using sensitive molecular tests should be a recommended course of action, especially in candidates for renal transplant.

    Moderate hyperhomocysteinemia, a risk factor for premature atherosclerosis, is present in chronic uremic patients. We prospectively evaluated the effects of sequential supplementation with pyridoxine (70 mg/day) and folic acid (10 mg/day) for two 3-month periods in 37 nondialyzed patients (29 males) with creatinine clearance (CCr) ranging from 10 to 80 ml/min, whose plasma vitamin B12 and folate level was in the normal range. Mean (+/- SD) baseline plasma total homocysteine (Hcy) was 14.9 +/- 5.2, 16.5 +/- 5.1 and 26.1 +/- 12.1 mumol/l (upper limit in 45 healthy controls 14.1 mumol/l) in patients with CCr 40-80, 20-40 and pyridoxine Hcy did not significantly decrease whereas following folic acid Hcy decreased significantly to 9.9 +/- 2.9 (-33% vs. baseline), 10.3 +/- 3.4 (-37%) and 15.4 +/- 5.5 (-40%), respectively (Student's paired t test, p pyridoxine) pharmacologic supplementation is effective in lowering elevated plasma Hcy in chronic renal failure patients, thus suggesting that enhancing the Hcy remethylation pathway may overcome hyperhomocysteinemia in such patients. In view of the potential atherogenic effects of hyperhomocysteinemia, long-term folate supplementation should be considered in uremic patients.

    There are many reports on pregnancy In chronic renal failure with creatinine (Cr levels ≤ 1.5 mg/dl, but pregnancy is uncommon when the levels are above this limit and specially over 3 mg/dl. It is likely that hormonal abnormalities involving low progesterone and high prolactine levels playa key role. We report on three cases with Cr levels equal to or greater than 6 mg/dl during pregnancy or after delivery. We recommend that Cr levels be determined in the initial follow-up of any woman who wishes to become pregnant.

    Se han publicado numerosos reportes de embarazo en pacientes con insuficiencia renal crónica, con creatinina (Cr ≤ 1.5 mg/dl, pero el embarazo es poco común con niveles de Cr mayores, principalmente ≥: 3 mg/dl.

Methods This prospective study was carried out in a cohort of 92 randomly selected patients with ESRF treated with hemodialysis (HD) and peritoneal dialysis (PD). The data regarding demographic and clinical characteristics were recorded, including vascular disease (coronary, cerebral, peripheral). The follow-up lasted 40 months and the final evaluation included the number and causes of deaths, CDV events and disease. Serum Ca, P, ALP, iPTH, albumin, cholesterol, urea and creatinine levels were measured. The plain radiographic films of hands and pelvis evaluated all bone abnormalities suggestive of renal osteodystrophy (ROD) and peripheral vascular calcification (VC). Results All-cause annual mortality represented 9.25% in HD and 9.09% in PD patients. The CDV mortality represented almost 44% in HD patients and 66% in PD patients from all deaths. There was a high prevalence of CDV diseases and events. High and low serum P levels were associated with a worse survival rate. Hypercalcaemia was associated with high risk for CDV events in HD patients. In PD patients, the relationship between increased ALP levels and all-cause mortality was significant. Other mineral markers were not predictive of the outcome in the studied patients. In the HD patients the severity of VC was associated with all-cause and CDV mortality, and with CDV events. Male gender, hypercholesterolemia, decreased URR, albumin and creatinine were identified as risk factors for all-cause mortality. The diabetics had higher

    Full Text Available Bacground/Aim. Chronic heart failure (CHF is highly prevalent and constitutes an important public health problem around the world. In spite of a large number of pharmacological agents that successfully decrease mortality in CHF, the effects on exercise tolerance and quality of life are modest. Renal dysfunction is extremely common in patients with CHF and it is strongly related not only to increased mortality and morbidity but to a significant decrease in exercise tolerance, as well. The aim of our study was to investigate the prevalence and influence of the renal dysfunction on functional capacity in the elderly CHF patients. Methods. We included 127 patients aged over 65 years in a stable phase of CHF. The diagnosis of heart failure was based on the latest diagnostic principles of the European Society of Cardiology. The estimated glomerular filtration rate (eGRF was determined by the abbreviated Modification of Diet in Renal Disease (MDRD2 formula, and patients were categorized using the Kidney Disease Outcomes Quality Initiative (K/DOQI classification system. Functional capacity was determined by the 6 minute walking test (6MWT. Results. Among 127 patients, 90 were men. The average age was 72.5 ± 4.99 years and left ventricular ejection fraction (LVEF was 40.22 ± 9.89%. The average duration of CHF was 3.79 ± 4.84 years. Ninty three (73.2% patients were in New York Heart Association (NYHA class II and 34 (26.8% in NYHA class III. Normal renal function (eGFR ≥ 90 mL/min had 8.9% of participants, 57.8% had eGFR between 60-89 mL/min (stage 2 or mild reduction in GFR according to K/DOQI classification, 32.2% had eGFR between 30-59 mL/min (stage 3 or moderate reduction in GFR and 1.1% had eGFR between 15-29 mL/min (stage 4 or severe reduction in GFR. We found statistically significant correlation between eGFR and 6 minute walking distance (6MWD (r = 0.390, p < 0.001, LVEF (r = 0.268, p < 0.05, NYHA class (ς = -0.269, p < 0.05 and age (r = - 0

    The aim of this investigation was to identify the prevalence of herpesvirus types 1-8 in the oral cavity of subjects with chronic renal failure (CRF) and healthy subjects and compare the two groups, and also correlate the presence of the virus with some characteristics of CRF disease (the type of treatment, drugs administered for CRF and the presence of oral manifestations). The sample was made up of 60 subjects (aged 4-20) divided into the renal group (RG) and healthy group. Anamnesis, intraoral examination and collection of clinical specimens (swab smears) were carried out. The nested-PCR technique was used to identify the viral species. The results showed a higher prevalence of HSV-1 (20%), human herpes virus (HHV)-6B (83%), CMV (13.3%) in RG group than in healthy group (HSV-1: 3.3%; HHV-6B: 20%) (P ≤ 0.05). There was no difference in the prevalence of HHV-7 between the two groups (P > 0.05). HSV-2, EBV, VZV, HHV-6A, and HHV-8 were not identified in either group. The most common symptoms in RG were dry-mouth sensation (60%), changes in taste (33.3%), and uremic odor (26.7%). There was a correlation between HHV-7 and the use of anticoagulants and HHV-6B with dry-mouth sensation (P ≤ 0.05). Based on the results, the prevalence of herpesvirus types (HSV-1, HHV-6B and CMV) were shown to be higher in subjects with CRF as well as in healthy children, but only the HHV-6B and HHV-7 were correlated with some of the disease characteristics. So, more attention should be paid to the oral health of these individuals in order to prevent infection by opportunistic pathogens.

    To assess the prevalence of Restless Legs Syndrome (RLS) in anemic patients with Congestive Heart Failure (CHF) and Chronic Renal Failure (CRF) and to evaluate the effect of anemia treatment on RLS. 38 anemic CHF-CRF patients were treated with subcutaneous Erythropoietin (EPO) and intravenous (IV) iron over 1 year. They were questioned initially and at 3 months post treatment about symptoms of RLS according to standard criteria. They were also contacted by telephone about RLS symptoms 12 months after onset of anemia treatment. RLS was found in 15 (39.5%) of the 38 patients. In 10 (66.7%) patients it was present at least 6 days a week. The prevalence of the RLS initially was not related to Hb, to serum iron or % Transferrin Saturation. Diabetes and lower serum ferritin were more common in the RLS group (pprevalence and frequency of RLS complaints was similar to what it had been initially. RLS is common and often undiagnosed and untreated in anemic CHF-CRF patients. Unfortunately, successful treatment of anemia with EPO and IV iron did not improve this condition.

    Objective To study the effects of Cordyceps sinensis (CS) on the metabolism of body protein and intra-extracellular amino acids in patients with chronic renal failure( CRF) , and on the rates of protein synthesis in rats with CRF. Methods In patients with CRF, free amino acid concentrations in plasma and skeletal muscle before and after CS treatment were measured by the LKB-4400 amino acid automatic analytical instrument and the changes of body protein metabolism were observed by the method of 15 N-labeled glycine.Meanwhile, the rates of protein synthesis in liver ( SL % /d ) and muscle (SM%/d) of rats with CRF were determinedd by 3f-phenylalanine radioactive tracer. Results After patients with CRF were treated by CS, the Leu, lie, Thr , Lys, Cys, Tyr concentrations in plasma approached the normal levels. In one sample of skeletal muscle the Thr and Lys concentrations approached the normal, whereas both the intracellular and extracellular Val concentrations were still remarkably decreased as compared with the normal controls. Moreover, the nitrogen flow rate (Q) , rates of protein synthesis (S) and catabolism ( C) , and amino nitrogen utilization ratio (S/Q) in patients with CRF and the SL % /d and SM%/d in rats with CRF were significantly increased as compared with those before CS treatment. Conclusion CS can notably improve the amino acid metabolism, promote the body protein synthesis in patients with CRF , and increase the rates of SL % /d and SM%/d in rats with CRF.

    Cardiac remodeling is one of the most common cardiac abnormalities and associated with a high mortality in chronic renal failure (CRF) patients. Apocynin, a nicotinamide-adenine dinucleotide phosphate (NADPH) oxidase inhibitor, has been showed cardio-protective effects. However, whether apocynin can improve cardiac remodeling in CRF and what is the underlying mechanism are unclear. In the present study, we enrolled 94 participants. In addition, we used 5/6 nephrectomized rats to mimic cardiac remodeling in CRF. Serum levels of epoxyeicosatrienoic acids (EETs) and its mainly metabolic enzyme-soluble epoxide hydrolase (sEH) were measured. The results showed that the serum levels of EETs were significantly decreased in renocardiac syndrome participants (P < 0.05). In 5/6 nephrectomized CRF model, the ratio of left ventricular weight / body weight, left ventricular posterior wall thickness, and cardiac interstitial fibrosis were significantly increased while ejection fraction significantly decreased (P < 0.05). All these effects could partly be reversed by apocynin. Meanwhile, we found during the process of cardiac remodeling in CRF, apocynin significantly increased the reduced serum levels of EETs and decreased the mRNA and protein expressions of sEH in the heart (P < 0.05). Our findings indicated that the protective effect of apocynin on cardiac remodeling in CRF was associated with the up-regulation of EETs. EETs may be a new mediator for the injury of kidney-heart interactions.

    We examined the mechanism of endothelial dysfunction in chronic renal failure (CRF), with reference to NO synthase. CRF was induced by 5/6 nephrectomy in rats. Either L-arginine (1.25 g/L in drinking water), tetrahydrobiopterin (BH4, 10 mg/kg per day in food), or a combination of the 2 were orally administered to CRF rats for 9 weeks. CRF rats showed elevation of systolic blood pressure compared with sham-operated rats. Endothelium-dependent relaxation induced by acetylcholine or A23187 in the isolated aorta was significantly reduced, and in vitro treatment with L-arginine, BH4, or superoxide dismutase restored the relaxation. Aortic segments from CRF rats showed significantly higher superoxide production in response to A23187, which was inhibited by L-NAME. Plasma concentrations of asymmetric dimethylarginine and symmetric dimethylarginine were higher in CRF rats. These changes in CRF rats were totally or partially decreased by L-arginine or BH4 supplementation in vivo. Interestingly, the combined treatment showed additive effects in certain parameters. These results suggest that vascular disorders in CRF rats may be partly due to NOS uncoupling caused by a relative deficiency of BH4 and partially due to accumulation of endogenous inhibitors of NOS and L-arginine uptake, resulting in the decrease of NO production and the increase of reactive oxygen species.

  7. Ciprofloxacin-Induced Renal Failure

    Full Text Available Acute renal failure (ARF is a common diagnosis in hospitalized patients, particularly in intensive care units (ICU. Determining the cause and contributing factors associated with ARF is crucial during treatment. The etiology is complex, and several factors often contribute to its development. Medications can cause acute tubular necrosis, acute interstitial nephritis, and crystal-induced or post-obstructive nephropathy. There have been several case reports of ARF secondary to fluoroquinolones. Here we report the development of acute renal failure within a few days of initiating oral ciprofloxacin therapy and briefly describe the different types of renal failure secondary to fluoroquinolone administration. Clinical studies demonstrate that using fluoroquinolones with other potentially nephrotoxic medications requires monitoring of renal function to limit the renal toxicity with these medications. Also, the risk-benefit profile of patients requiring fluoroquinolones should be considered.

    Malnutrition is very prevalent among patients with chronic renal failure. The role of derangements in the gut-brain axis for regulation of appetite in the genesis of anorexia of these patients has not been adequately investigated. Design. Following a randomized, crossover design, we analysed plasma levels of peptide YY (PYY)(1-36) and PYY(3-36) both fasting and after a standardized oral mixed meal or intraperitoneal glucose infusion in 10 stable uraemic patients undergoing peritoneal dialysis and 8 healthy controls, matched for age, gender and body mass index. Main results. Median baseline plasma levels of PYY(1-36) in the different provocation tests oscillated between 406 and 460 pg/mL in patients, as compared with 73 and 100 pg/mL in controls (P anorexia of chronic renal failure.

    Together with the prolongation and improving the quality of life of young women with chronic renal failure (CRF), procreation becomes an important issue. Pregnancies in women on renal replacement therapy are associated with an increased risk of health complications, both for mothers and for fetuses. Medical management of pregnant women with CRF is a great challenge and requires a close co-operation of nephrologists, transplantologists, gynecologists and neonatologists. The complexity of problems in these particular pregnancies has urged us to describe the case of a woman with CRF who successfully delivered two babies. We also review the current state of knowledge on the topic. The first pregnancy five years after renal transplantation, was completed with the delivery of term newborn with Tetralogy of Fallot. Also the second pregnancy on hemodialysis therapy was finished by the birth of a healthy neonate at term. The described case indicates that the gynecologists should be prepared for the challenge of the care for pregnancies in women suffering from chronic renal failure on renal replacement therapy.

    Kidney injury associated with lymphocytic leukemia (CLL) is typically caused by direct tumor infiltration which occasionally results in acute renal failure. Glomerular involvement presenting as proteinuria or even nephrotic syndrome is exceptionally rare. Here we report a case of 54-year-old male CLL patient with nephrotic syndrome and renal failure. The lymph node biopsy confirmed that the patients had CLL with remarkable immunoglobulin light chain amyloid deposition. The renal biopsy demonstrated the concurrence of AL amyloidosis and neoplastic infiltration. Combined treatment of fludarabine, cyclophosphamide and rituximab resulted in remission of CLL, as well as the renal disfunction and nephrotic syndrome, without recurrence during a 12-month follow-up. To our knowledge, this is the first case of CLL patient showing the nephrotic syndrome and acute renal failure caused by AL amyloidosis and neoplastic infiltration. Though AL amyloidosis caused by plasma cell dyscrasia usually responses poorly to chemotherapy, this patient exhibited a satisfactory clinical outcome due to successful inhibition of the production of amylodogenic light chains by combined chemotherapy.

    Background Hyperphosphatemia in renal failure has been identified as a major role in the pathogenesis of hyperparathyroidism that is independent of changes in serum calcium and 1,25(OH)2D3. The aim of this study was to evaluate the expression of parathyroid Pit-1 in hyperphosphatemia-induced secondary hyperparathyroidism (SHPT) of chronic renal failure (CRF) rats.Methods Wistar rats with CRF induced by 5/6 nephrectomy were ramdomly fed with diet containing 1.2% inorganic phosphate (Pi, high phosphate (HP) group, n=9) or 0.2% Pi (low phosphate (LP) group, n=9) for 10 weeks starting from the fourth week after the surgery. Another 7 nephrectomy rats with HP diet were intraperitoneally injected with phosphonoformic acid (PFA, the specific inhibitor of Pit-1, HP+PFA group) 0.15 g/kg every other day for 10 weeks starting from HP diet. Another 6 HP rats injected with the same amount of normal saline as the control of the HP+PFA group (HP+saline group). At the same time, 9 rats with sham surgery received HP diet as the controls. At the 4th week and 14th week, blood was taken for measurement of serum creatinine (SCr), serum calcium (SCa), serum phosphorus (SPi),1,25(OH)2D3 and intact parathyroid hormone (iPTH). At the 14th week, two parathroid glands (PTGs) of each rat were removed by microsurgery, one gland for immunohistochemistry analysis of proliferating cell nuclear antigen (PCNA), the other one for detection of Pit-1 by Western blotting, and for the measurement of Pit-1 mRNA and PTH mRNA by real-time quantitative polymerase chain reaction.Results In nephrectomy rats, high dierary phosphate induced a marked increase in serum phosphate, iPTH, PTH mRNA and PCNA parathyroid cells, accompanying Pit-1 and its mRNA in parathyroid gland increased significantly.However, serum Ca and 1,25(OH)2D3 remained unchanged. PFA decreased Pit-1 and its mRNA levels to reduce intact PTH, PTH mRNA and PCNA-positive parathyroid cells.Conclusions Expression of parathyroid Pit-1 in

    Subclinical hyperthyroidism is an increasingly recognized entity that is defined as a normal serum free thyroxine and free triiodothyronine levels with a thyroid-stimulating hormone level suppressed below the normal range and usually undetectable. Paroxysmal atrial fibrillation is a frequent complication of acute myocardial infarction. It has been reported that subclinical hyperthyroidism is not associated with coronary heart disease or mortality from cardiovascular causes but it is sufficient to induce arrhythmias including an increase in atrial fibrillation rate. It has also been reported that increased factor X activity in patients with subclinical hyperthyroidism represents a potential hypercoagulable state. Moreover chronic renal failure presents an increased arrhythmic risk. Apparently spurious result has been reported in a work about mean serum prostate-specific antigen (PSA) concentration during acute myocardial infarction with mean serum PSA concentration significantly lower on day 2 than either day 1 or day 3 and it has been reported that these preliminary results could reflect several factors, such as antiinfarctual treatment, reduced physical activity or an acute-phase response. We present a case of paroxysmal ventricular tachycardia and paroxysmal atrial fibrillation associated with subclinical hyperthyroidism, chronic renal failure and elevation of serum PSA concentration in a 90-year-old Italian man during acute myocardial infarction. Also this case focuses attention on the importance of a correct evaluation of subclinical hyperthyroidism and of chronic renal failure. Moreover, our report also confirms previous findings and extends the evaluation of PSA during acute myocardial infarction.

    Since more than two decades erythropoiesis-stimulating agents are the main pillar for treatment of anemia associated with chronic kidney disease. Methoxy polyethylene glycol-epoetin beta (MPG-EPO), also called continuous erythropoietin receptor activator, is the longest acting erythropoiesis-stimulating agent currently available. MPG-EPO is characterized by an elimination half-life of approximately 137 h and offers extended dosing intervals up to 4 weeks. Numerous phase I/II studies and a comprehensive clinical phase III program demonstrated the feasibility of MPG-EPO therapy for anemia correction and maintenance of stable hemoglobin levels in adult chronic kidney disease patients. Due to patent disputes MPG-EPO was only available outside the US market so far. In view of a prevailing US market introduction, this review focuses on efficacy and safety data from pivotal trials, summarizes recent clinical research and finally tries to substantiate potential benefits associated with the use of this anti-anemic drug.

    The technique and outcome of surgery for the manifestations of secondary hyperparathyroidism are described. Forty-seven patients were analysed retrospectively over a 10-year period. Total parathyroidectomy and autotransplantation to the forearm was performed in all but five patients. Improvement occurred in 87 per cent of patients and there were no graft failures. Of six deaths, none was related to surgery. Four patients had recurrent hyperparathyroidism, three being graft dependent and one requiring re-exploration of the neck. Total parathyroidectomy and autotransplantation is a safe and effective approach. The major management problem was graft hyperplasia, seen in three of the 47 patients and managed by simple excision.

    2012-07-01

    After broad cardiological and nephrological evaluation and consideration of optimal conservative options according to national and international guidelines, renal replacement therapy might be helpful in patients with refractory heart failure even if they are not dialysis-dependent. This is even more important as renal failure is a strong predictor for mortality in patients with severe congestive heart failure (CHF) and CHF is one of the fastest growing morbidities in western countries. Although peritoneal dialysis (PD) is frequently used in patients with CHF its role remains unclear. Acute chronic volume overload in refractory CHF is still an unresolved clinical problem. In patients with acute heart and renal failure with need of management in an intensive care unit, extracorporeal ultrafiltration or a dialysis modality should be preferred. In patients with chronic refractory CHF, volume overload and renal failure, peritoneal dialysis should be the therapy of choice. Due to the limited data available, treatment and outcome parameters should be recorded in the registry of the German Society of Nephrology (http://www.herz-niere.de).

    The success of maintenance haemodialysis in the 1960s was blighted by the problem of anaemia. Treatment with iron, folic acid, androgens and transfusions did no more than minimize its effects. The need for a renewable source of erythropoietin was appreciated very early but the hope took 25 years to realize. Cloning and expression of the human gene was achieved in 1984 and clinical trials planned even before the descriptions of the recombinant hormone were published. The Amgen material was tested in parallel studies in Seattle and England and by the end of 1986 the efficacy of recombinant human erythropoietin (r-HuEPO) given in large intravenous bolus doses in reversing the anaemia of uraemia was established. The benefits were immediately obvious: relief from transfusion dependence was the unequivocal evidence but the effect on 'wellbeing' though subjective was remarkable. Large clinical trials were completed in Europe and the USA so that r-HuEPO was licensed as a therapeutic drug less than two years later. The pilot studies flagged a number of key issues: hypertension, sometimes with encephalopathy, occurred in patients whose blood pressure was labile before treatment; vascular access failure seemed more frequent and hyperkalaemia was thought to reflect less efficient dialysis. Failure to respond focused attention on iron balance as well as on factors such as infection, aluminium, and hyperparathyroidism. A more clear understanding of the pathogenesis of the anaemia of uraemia was made possible by dissection of the specific effects of the exogenous erythropoietin on erythroid function.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available An 80-year-old man was diagnosed to have pneumonia and advanced chronic kidney disease. He presented with anuria and hemodialysis, by temporary femoral catheter, was initiated. He was empirically treated with imipenem/cilastatin 500 mg/24 h after hemodialysis. After 10 days of antibiotic intake, he developed severe diarrhea. Diagnosis of Clostridium difficile (CD-associated diarrhea was confirmed by detection of the toxins A and B in his stool. Imipenem therapy was discontinued; Vancomycin 500 mg orally every 6 h and 1000 mg per rectum every day was added. After two weeks of this treatment, the patient reported complete resolution of the diarrhea and stool samples were negative for Clostridium toxin. In this case, the most possible cause of CD colitis was considered to be imipenem because of the temporal relationship between exposure to the drug and onset of symptoms.

    Full Text Available Introduction There have been many publications in the past 20 years about positive effects of human recombinant erythropoietin, which is used in treatment of anemia, especially in patients on dialysis. Complications The most important complications in patients treated with erythropoietin include: hypertensive reactions; thrombosis of AV fistula in patients on hemodialysis and appearance of severe anemia as a part of Pure Red Cell Aplasia (PRCA. The first two complications were managed quite easily with adequate erythropoietin dosage, and slower establishment of normal hemoglobin kevel, hematocrit level and red blood cell count, (our "target" Hb varied between 100 and 110 g/dl. Pure Red Cell Aplasia (PRCA Pure Red Cell Aplasia is a progressive, marked anemia with sudden appearance of signifacnt loss or complete absence of erythrocyte precursor cells in normal bone marrow. In patients with end stage renal disease treated with erythropoietin PRCA appears in acute form as a consequence of production of neutralizing antibodies to erythropoietin. Time period between the beginning of erythropoietin therapy and appearance of PRCA is from 3 weeks to approximately 9 months. Symptoms and signs PRCA is characterized by sudden appearance of anemia in patients who had a satisfactory response to erythropoietin therapy till that moment. In PRCA, anemia is normocytic, normochromic with normal survival of red blood cells, without deficit in components such as iron, folic acid or vitamin B12, low reticulocyte count, decrease in Hg and normal platelet count. Diagnosis Diagnosis is based on clinical data (marked anemia, bone marrow biopsy, which shows a lower number of precursor red blood cells and presence of antibodies against erythropoietin. Before PRCA is diagnosed, all other causes for erythropoietin resistance must be excluded. Therapy Therapy of PRCA is based on cessation of erythropoietin therapy (all kinds, and correction of anemia with blood transfusions

    Iodine ablation therapy for thyroid cancer on patients receiving dialysis poses unique radiation safety challenges. Exposure to gamma and beta negative particles by the hemodialysis (HD) staff is a concern that has not been well studied. A 53-y-old male patient on HD for chronic renal failure was scheduled for 131I high dose therapy as treatment for thyroid papillary carcinoma. The patient was on HD every other day, prior to ablation. A high dose of 131I (3,607.5 MBq) was required. The patient was admitted for 131I therapy, and continued HD. Thyroid cancer ablation therapy was administered according to our institutional protocol. New radiation safety measures were developed and implemented in order to give the patient an optimal treatment dose, reduce radiation to the patient (critical organs and whole body), and to protect the HD personnel. This included placing two lead shields between the patient and the HD nurse, and HD monitoring by two alternating nurses to reduce their radiation exposure. Film badges were used to measure radiation exposure to the nursing staff. Dosimetry calculations were obtained to determine radiation absorbed doses by the optic lens, skin, and whole body. Quality control verification for this shielding arrangement proved to be effective in protecting the HD staff against gamma and beta negative radiation from recent 131I high dose therapy. Implementation of this model proved to be an effective and adequate radiation safety protocol for limiting radiation exposure to the HD staff. The patient was given 3607.5 MBq for optimal treatment after HD. Hemodialysis was repeated after approximately 48 and 96 h to remove excess 131I and reduce radiation to the patient.

    Patients with chronic renal failure (CRF) receive recombinant human erythropoietin (rhEPO) for the correction of anemia. However, rhEPO also has an immunomodulatory effect. Detailed changes of phenotype and function of CD4(+) T lymphocytes in CRF patients receiving rhEPO have not been reported yet; their study may bring insight into understanding of this immunomodulatory action of rhEPO. Two groups of CRF patients were included into the study: those treated; and those not receiving rhEPO. The expression of activation markers on CD4(+) lymphocytes was measured with flow cytometry, both ex vivo and in vitro. The kinetics of CD4(+) T lymphocytes proliferation was calculated using a dividing cells tracing method and numerical approach. Significantly higher percentages of CD4(+)CD95(+), CD4(+)HLA-DR(+) cells, and lower percentages of CD4(+)CD69(+) and CD4(+)CD28(+) cells were observed in both rhEPO-treated and untreated patients when compared with healthy controls. Changes in the proportions of CD4(+)CD28(+) and CD4(+)HLA-DR(+) subpopulations were dependent on the type of rhEPO, being more pronounced for rhEPObeta. CD4(+) lymphocytes from untreated patients exhibited decreased expression of CD28 and CD69 after stimulation in vitro, whereas the expression of these antigens on lymphocytes of rhEPO-treated patients was similar to that observed in healthy controls. Fewer CD4(+)CD28(+) T lymphocytes of untreated patients proliferated in vitro; these cells had longer G0-->G1 time, which negatively correlated with surface expression of CD28. Our study confirms that rhEPO treatment normalizes activation parameters of CD4(+) T lymphocytes and their proliferative capacity, which could explain earlier described immunomodulatory effects of rhEPO in patients suffering from CRF.

    The kidney has numerous complex interactions with the heart, including shared risk factors (e.g., hypertension, dyslipidemia, etc.) and mutual amplification of morbidity and mortality. Both cardiovascular diseases and chronic kidney disease (CKD) may cause various alterations in cardiovascular system, metabolic homeostasis and autonomic nervous system that may facilitate the occurrence of cardiac arrhythmias. Also, pre-existent or incident cardiac arrhythmias such as atrial fibrillation (AF) may accelerate the progression of CKD. Patients with CKD may experience various cardiac rhythm disturbances including sudden cardiac death. Contemporary management of cardiac arrhythmias includes the use of antiarrhythmic drugs (AADs), catheter ablation and cardiac implantable electronic devices (CIEDs). Importantly, AADs are not used only as the principal treatment strategy, but also as an adjunct therapy in combination with CIEDs, to facilitate their effects or to minimize inappropriate device activation in selected patients. Along with their principal antiarrhythmic effect, AADs may also induce cardiac arrhythmias and the risk for such proarrhythmic effect(s) is particularly increased in patients with reduced left ventricular systolic function or in the setting of electrolyte imbalance. Moreover, CKD itself can induce profound alterations in the pharmacokinetics and pharmacodynamics of many drugs including AADs, thus facilitating the drug accumulation and increased exposure. Hence, the use of AADs in patients with CKD may be challenging. In this review article, we provide an overview of the characteristics of arrhythmogenesis in patients with CKD with special emphasis on the complexity of pharmacokinetics and risk for proarrhythmias when using AADs in patients with cardiac arrhythmias and CKD.

    Full Text Available Introduction: Patients with chronic kidney disease (CKD show an increase in bowel aerobic bacteria that produce uremic toxins and decreased anaerobic bacteria as bifidobacteria and lactobacillus. The latter can be used as probiotics. The probiotic with greater availability in Mexico, is the lactobacillus casei shirota (LcS, currently there is no known LcS specified dose that produces a benefit to the patient with CKD. Objective: To determine the effectiveness of two different LcS doses in achieving a decrease in urea concentrations of at least 10% in patients with KDOQI stage 3 and stage 4 CKD. Metodology: A simple randomized, controlled clinical trial. Outpatients treated at the National Institute of Medical Sciences and Nutrition Salvador Zubiran in Mexico D.F. Patients were provided the LcS, as follows: Group A: 8 x 10(9 colony-forming units (CFU and Group B: 16 x 10(9 CFU. Patients were followed-up for eight weeks, and baseline and final samples were obtained to calculate the basal and final concentrations, respectively, of blood urea and serum creatinine (CrS. During the follow-up, both groups consumed a diet of 30 kcal/kg/weight and 0.8 g/kg/weight of protein, and a food diary was made to assess both the adherence to the diet and LcS. Results: Thirty patients with CKD were evaluated. When analyzing the percentage change between the different doses, a decrease > 10% was found in the blood urea concentrations for patients treated with the 16 x 10(9 dose, which was significant with respect to the baseline measurement. Conclusion: There was a > 10% decrease in the serum urea concentrations with LcS in patients with stage 3 and 4 CRF.

    The discovery of chronic renal failure in a child, and the meaning of this experience from the perspective of the child's family caregivers have previously not been described in the literature on aboriginal health. During the summer of 1995, a phenomenological approach was used to explore this phenomena with 10 urban aboriginal family caregivers. These caregivers were providing care for their children who were receiving health care services at the outpatient children's clinic or the transplant unit at one urban tertiary care hospital. The findings of this research have helped create the beginning of a nursing data base of knowledge about aboriginal family caregivers of children who have chronic renal failure. In this paper, three of the main themes: surviving; relocation; enhancing power; and five sub-themes: providing nutrition; getting involved; educating the caregivers; educating the community; and returning to traditional ways are described. Implications of the findings for health care providers of children who have renal failure and their family caregivers are discussed. Issues that need to be addressed to help meet the needs of aboriginal family caregivers are identified. These issues include communication strategies, culturally appropriate teaching methods, access to resources, and community development initiatives.

  19. Axl tyrosine kinase protects against tubulo-interstitial apoptosis and progression of renal failure in a murine model of chronic kidney disease and hyperphosphataemia.

    Full Text Available Chronic kidney disease (CKD is defined as the progressive loss of renal function often involving glomerular, tubulo-interstitial and vascular pathology. CKD is associated with vascular calcification; the extent of which predicts morbidity and mortality. However, the molecular regulation of these events and the progression of chronic kidney disease are not fully elucidated. To investigate the function of Axl receptor tyrosine kinase in CKD we performed a sub-total nephrectomy and fed high phosphate (1% diet to Axl+/+ and Axl-/- mice. Plasma Gas6 (Axl' ligand, renal Axl expression and downstream Akt signalling were all significantly up-regulated in Axl+/+ mice following renal mass reduction and high phosphate diet, compared to age-matched controls. Axl-/- mice had significantly enhanced uraemia, reduced bodyweight and significantly reduced survival following sub-total nephrectomy and high phosphate diet compared to Axl+/+ mice; only 45% of Axl-/- mice survived to 14 weeks post-surgery compared to 87% of Axl+/+ mice. Histological analysis of kidney remnants revealed no effect of loss of Axl on glomerular hypertrophy, calcification or renal sclerosis but identified significantly increased tubulo-interstitial apoptosis in Axl-/- mice. Vascular calcification was not induced in Axl+/+ or Axl-/- mice in the time frame we were able to examine. In conclusion, we identify the up-regulation of Gas6/Axl signalling as a protective mechanism which reduces tubulo-interstitial apoptosis and slows progression to end-stage renal failure in the murine nephrectomy and high phosphate diet model of CKD.

    Ischemic heart disease and other complications of atherosclerosis are the usual cause of death in patients with chronic renal failure. Important factors associated with early onset of atherosclerosis in these patients are hyperhomocysteinemia, hyperfibrinogenemia, and elevated levels of lipoprotein(a) (Lp(a)). Folic acid (15 mg/d), pyridoxine (150 mg/d), and cyanocobalamin (1 mg/wk) were administered for 4 weeks in 21 patients receiving dialysis, and a simultaneous, statistically significant reduction in the concentration of homocysteine, fibrinogen, and Lp(a) was found. A positive correlation between decreasing homocysteine and fibrinogen levels was also noted. The parameters studied approached presupplementation values 6 months after vitamins were discontinued. The results suggest that vitamin supplementation has a favorable effect on risk factors of atherosclerosis in patients with renal failure and that interactions may exist between homocysteine, fibrinogen, and Lp(a).

    This article reviews our current understanding of the mechanisms of growth failure in chronic renal disease. The neuro-endocrine control of growth hormone secretion and insulin-like growth factor gene expression subject to use of corticosteroids, uremia, and metabolic acidosis are presented. It has been shown in other non-growth hormone deficient conditions such as Turner's syndrome that the use of exogenous growth hormone increases linear growth but also accelerates closure of the growth plate with no significant difference in the final height of such children. An understanding of growth factors is especially important and timely because of the tendency these days to use growth hormone to overcome the growth impairment of children with chronic renal failure.

    Full Text Available Chronic renal failure (CRF is a serious disease related to increasing incidence and prevalence as well as decline in quality of life. Bu-Shen-Huo-Xue formula (BSHX, one of traditional herbal formulations, has been clinically employed to treat CRF for decades, but the mechanisms involved have not been investigated. In the present study, we investigated the effects of BSHX on some closely related parameters in 5/6 nephrectomy CRF rats. Rats with CRF were divided into five groups, namely, one control group, one enalapril group, and three BSHX treatment groups (0.25, 0.5, and 1 g/kg·d. The rats subjected to sham operation were used as a normal control. After eight weeks of treatment, BSHX significantly decreased the levels of Scr and BUN, downregulated the mRNA expression levels of TGF-β1, CTGF, NF-κB, TNF-α, and OPN, upregulated the mRNA expression of PPARγ, and reduced in situ expression of fibronectin and laminins. Histological findings also showed significant amelioration of the damaged renal tissue. BSHX protects 5/6 nephrectomy rats against chronic renal failure probably via regulating the expression of TNF-α, NF-κB, TGF-β1, CTGF, PPARγ, OPN, fibronectin, and laminins and is useful for therapy of CRF.

    Patients with chronic renal failure (CRF) often have autonomic cardiac dysfunction, which can be assessed by measuring heart rate variability (HRV). This dysfunction prediposes the patients to sudden cardiac death. This study describes 24-hour HRV in patients with CRF compared to HRV in patients with a previous myocardial infarction (MI). Furthermore, associations between HRV in patients with CRF and the content of n-3 polyunsaturated fatty acids (PUFA) in cell membranes were examined, because n-3 PUFA may improve HRV. Twenty-nine patients with CRF treated with dialysis were enrolled. A 24-hour Holter recording was obtained at baseline and the HRV variables, RR (= mean of all normal RR intervals during the 24-hour recording) and SDNN (= standard deviation of all normal RR intervals in the entire 24-hour recording) were analyzed. Also, granulocyte fatty acid composition was determined. The patients were allocated to dietary supplementation with either 5.2 g of n-3 PUFA or a placebo oil (olive oil) daily for 12 weeks in a double-blind design. At the end of the supplementation period the Holter recording and blood sampling were repeated. At baseline the CRF patients' mean SDNN ws 86 ms compared to 118 ms (p < 0.01) in patients with a previous MI. After supplementation with either n-3 PUFA or placebo a highly significant correlation was observed between the content of n-3 PUFA in cell membranes and HRV (r = 0.71, p < 0.01). Furthermore, when the patients were dichotomized according to their mean SDNN, it was found, that those with the highest SDNN had a higher content of n-3 PUFA in cell membranes compared to those with the lowest SDNN (7.8% vs 4.2%, p < 0.05). In conclusion, HRV was decreased in CRF patients indicating a cardiovascular autonomic dysfunction. The positive correlation between the n-3 PUFA content in cell membranes and HRV suggests that the effects of an increased intake of n-3 PUFA in CRF patients should be further studied.

    Renal dysfunction is encountered in 20-25% of patients with multiple myeloma (MM) at the time of diagnosis. There is often a precipitating event. Several biochemical and clinical correlations with renal failure in MM have been reported. Renal failure in MM is associated with worse outcome of the disease. We retrospectively analyzed the medical records of 64 patients with MM admitted to our institution during the period January 1992 to December 2012. Abnormal renal function was observed in 24 (37.5%) patients and 17 (26.6%) of them had renal failure; 14 of the 17 (82.4%) of patients with renal failure had Stage III MM. Urine Bence- Jones protein was positive in ten (58.8%) patients with renal failure versus ten (21.3%) patients without renal failure (P = 0.004). Potential precipitating factors of renal failure were determined in nine patients. Renal function normalized in 11 patients with simple measures, while six patients required hemodialysis; one remained dialysis dependent till time of death. Early mortality occurred in five (29.4%) patients with renal failure as compared with two (4.3%) patients in the group without renal failure (P = 0.005). In conclusion, renal failure is associated with a higher tumor burden and Bence-Jones proteinuria in patients with MM. It is reversible in the majority of patients; however, early mortality tends to be higher in patients with persistent renal failure.

    The efficacy and safety of recombinant canine erythropoietin (rcEPO) therapy was evaluated in 19 dogs with anemia of chronic renal failure (group 1) and 6 dogs with chronic renal failure and recombinant human erythropoietin (rhEPO)-induced red cell aplasia (group 2). Hematocrit (Hct) and absolute reticulocyte count (ARC) were monitored weekly for the first 8 weeks, CBC (including ARC) and serum iron profiles were evaluated monthly, and serum biochemical analyses were performed every 2 months for 6 (group 2) to 12 (group 1) months. For group 1 dogs, median Hct and ARC increased significantly during the 1st week of rcEPO treatment, and median Hct was sustained at >35% after week 5. In contrast, median Hct and ARC for group 2 did not change significantly with rcEPO treatment, even with doses greater than those used in group 1. Nevertheless, 2 (33%) of the 6 dogs in group 2 developed erythroid hyperplasia, reticulocytosis, and increases in Hct with rcEPO treatment. Although median systolic blood pressure did not change significantly in either group, 5 dogs developed systolic blood pressures > or = 180 mm Hg during the study. Appetite and energy level improved in most group 1 dogs with increases in Hct. Recombinant cEPO stimulated erythrocyte production in dogs with nonregenerative anemia secondary to chronic renal failure without causing the profound erythroid hypoplasia that can occur in rhEPO-treated dogs. Unfortunately, rcEPO was not as effective in restoring erythrocyte production in dogs that had previously developed rhEPO-induced red cell aplasia.

    The influence of different treatment modalities on the risk of developing major depression in patients with chronic renal failure (CRF) is not well understood. We aimed to explore the incidence of major depression among patients with CRF who were on different dialysis modalities, who had received renal transplantation (RT), and those who had not yet received any of the aforementioned renal replacement therapies. We conducted a population-based retrospective cohort study using a national health insurance research database. This study investigated 89,336 study controls, 17,889 patients with chronic kidney disease on conservative treatment, 3823 patients on hemodialysis (HD), 351 patients on peritoneal dialysis (PD), and 322 patients who had RT. We followed all individuals until the occurrence of major depression or the date of loss to follow-up. The PD group had the highest risk (hazard ratio [HR] 2.43; 95% confidence interval [CI] 1.26-4.69), whereas the RT group had the lowest risk (HR 0.18; 95% CI 0.03-1.29) of developing major depression compared with the control group. Patients initiated on PD had a higher risk of developing major depression than patients initiated on HD (pairwise comparison: HR 2.20; 95% CI 1.09-4.46). Different treatment modalities are associated with different risks of developing major depression in patients with CRF. Among renal replacement therapies, patients who have had RT have the lowest risk of developing major depression. Patients who initiate renal therapy on PD may have a higher risk of major depression compared with patients who initiate renal therapy on HD.

Hypogonadism in men with renal failure carries with it significant morbidity, including anemia and premature cardiovascular disease. It remains unclear whether testosterone therapy can affect the morbidity and mortality associated with renal failure. As such, in this review, we sought to evaluate the current literature addressing hypogonadism and testosterone replacement, specifically in men with renal failure. The articles chosen for this review were selected by performing a broad search using Pubmed, Embase and Scopus including the terms hypogonadism and renal failure from 1990 to the present. This review is based on both primary sources as well as review articles. Hypogonadism in renal failure has a multifactorial etiology, including co-morbid conditions such as diabetes, hypertension, old age and obesity. Renal failure can lead to decreased luteinizing hormone production and decreased prolactin clearance that could impair testosterone production. Given the increasing prevalence of hypogonadism and the potential morbidity associated with hypogonadism in men with renal failure, careful evaluation of serum testosterone would be valuable. Testosterone replacement therapy should be considered in men with symptomatic hypogonadism and renal failure, and may ameliorate some of the morbidity associated with renal failure. Patients with all stages of renal disease are at an increased risk of hypogonadism that could be associated with significant morbidity. Testosterone replacement therapy may reduce some of the morbidity of renal failure, although it carries risk.

    Scintigraphic localisation of parathyroid glands is often unsuccessful in patients with renal failure on chronic haemodialysis who have secondary hyperparathyroidism (HPT). The purpose of this study was to investigate the use of {sup 11}C-methionine PET/CT to detect hyperfunctioning parathyroid glands in patients with renal failure on chronic haemodialysis who had {sup 99m}Tc-sestamibi-negative HPT. {sup 11}C-methionine PET/CT was performed in 18 patients (11 women and 7 men, aged 42-79 years; mean age 57.8 years) on haemodialysis for renal failure (2-14 years' duration), with normo-, hypo- or hypercalcaemia and HPT not localised by either dual-tracer {sup 99m}Tc-pertechnetate/{sup 99m}Tc-sestamibi subtraction scans or dual-phase {sup 99m}Tc-sestamibi scans. In three of ten patients with normo- or hypocalcaemic HPT there was increased {sup 11}C-methionine accumulation in one gland. Seven of eight patients with hypercalcaemic HPT showed increased uptake: in five of these patients increased {sup 11}C-methionine accumulation was present in one gland, while in two it was demonstrated in two glands. All patients also had high-resolution ultrasound of the neck and were treated with subtotal parathyroidectomy, leaving a remnant of the smallest of the four glands. Regardless of their size, all glands with abnormal {sup 11}C-methionine parathyroid uptake were removed, and all demonstrated parathyroid hyperplasia. All patients developed post-parathyroidectomy hypoparathyroidism and one patient with normocalcaemic HPT relapsed 8 months after surgery. These data suggest that {sup 11}C-methionine PET/CT may be used to identify hyperfunctioning parathyroid glands in non-primary HPT, and especially hypercalcaemic HPT, when conventional {sup 99m}Tc-sestamibi imaging is non-localising.

    Acute renal failure (ARF) in a neonate is a serious condition that impacts 8% to 24% of hospitalized neonates. There is a need for prompt evaluation and treatment to avoid additional complications. In this review, a neonate was found to have renal failure associated with renal vein thrombosis. There are varying etiologies of ARF. Causes of ARF are typically divided into three subsets: pre-renal, renal or intrinsic, and post-renal. Treatment of ARF varies based on the cause. Renal vein thrombosis is an interesting cause of renal or intrinsic ARF and can be serious, often leading to a need for dialysis.

    Full Text Available Introduction: Chronic renal disease (CRD can compromise nutritional status in children. Nutritional assessment should be performed in early stages of CRD in order to maintain growth, as well as to prevent malnutrition and to diminish progression of renal diseases and metabolic consequences of uremia. Objective: Evaluation of nutritional status of children with moderate CRD stages 2- 4 by means of anthropometry, biochemical profile and dietary survey by records of last three days. Methods: A descriptive observational study was performed to a total of 17 patients that attended to pediatric nephrology service at the Hospital Universitario del Valle, from December 2007 to March 2008. Results: Of the children 65% were males, mean age was 6.2 for males and 10.3 for females. Causes of CRD were reflux nephropathy in 41%. Malnutrition under-2 Standard Deviation for height and weight for the age was found in 30% of patients. The measurement of triceps fold, showed moderate undernourishment in 75% of the children. According to the biochemical data 5 patients (29% had serum albumin Conclusions: These results support that an early nutritional intervention, is essential in children with of CRD in early stages; nutritional deficiencies were found in early stages of disease. It is essential to consume 100% of calories and other nutrients to avoid growth deficit and other important alterations.

    Exposure to organic solvents has been suggested to cause or exacerbate renal disease, but methodologic concerns regarding previous studies preclude firm conclusions. We examined the role of organic solvents in a population-based case-control study of early-stage chronic renal failure (CRF). All native Swedish residents aged 18 to 74 yr, living in Sweden between May 1996 and May 1998, formed the source population. Incident cases of CRF in a pre-uremic stage (n = 926) and control subjects (n = 998), randomly selected from the study base, underwent personal interviews that included a detailed occupational history. Expert rating by a certified occupational hygienist was used to assess organic solvent exposure intensity and duration. Relative risks were estimated by odds ratios (OR) in logistic regression models, with adjustment for potentially important covariates. The overall risk for CRF among subjects ever exposed to organic solvents was virtually identical to that among never-exposed (OR, 1.01; 95% confidence interval [CI], 0.81 to 1.25). No dose-response relationships were observed for lifetime cumulative solvent exposure, average dose, or exposure frequency or duration. The absence of association pertained to all subgroups of CRF: glomerulonephritis (OR, 0.96; 95% CI, 0.68 to 1.34), diabetic nephropathy (OR, 1.02; 95% CI, 0.74 to 1.41), renal vascular disease (OR, 1.16; 95% CI, 0.76 to 1.75), and other renal CRF (OR, 0.92; 95% CI, 0.66 to 1.27). The results from a nationwide, population-based study do not support the hypothesis of an adverse effect of organic solvents on CRF development, in general. Detrimental effects from subclasses of solvents or on specific renal diseases cannot be ruled out.

    Full Text Available Malaria has protean clinical manifestations and renal complications, particularly acute renal failure that could be life threatening. To evaluate the incidence, clinical profile, out-come and predictors of mortality in patients with malarial acute renal failure, we retrospectively studied the last two years records of malaria induced acute renal failure in patients with peripheral smear positive for malarial parasites. One hundred (10.4% (63 males, 37 females malaria induced acute renal failure amongst 958 cases of acute renal failure were evaluated. Plasmodium (P. falciparum was reported in 85%, P. vivax in 2%, and both in 13% patients. The mean serum creatinine was 9.2 ± 4.2 mg%, and oligo/anuria was present in 82%; 78% of the patients required hemodialysis. Sixty four percent of the patients recovered completely, 10% incompletely, and 5% developed chronic kidney failure; mortality occurred in 21% of the patients. Low hemoglobin, oligo/anuria on admission, hyperbilirubinemia, cerebral malaria, disseminated intravascular coa-gulation, and high serum creatinine were the main predictors of mortality. We conclude that ma-laria is associated with acute renal failure, which occurs most commonly in plasmodium falci-parum infected patients. Early diagnosis and prompt dialysis with supportive management can reduce morality and enhance recovery of renal function.

    Full Text Available Increasing number of chronic renal failure (CRF patients had reflected an increase in the number of patients with diabetes and hypertension. Therefore, health practitioners would be faced with management of complicated medical problems for the patients of chronic renal disease. In this way, various complications of chronic renal failure would lead to polypharmacy, where the patients receive three to five drugs in a dose. Development of polypharmacy had made the potential of drug interaction greater. The objective was to determine whether CRF patients admitted to hospital with specific adverse drug reactions were likely to have been prescribed with interacting drugs. Retrospective study was designed. The study was conducted at the General Practice Rooms Floor 1 – Floor VI of Central Army Hospital Gatot Soebroto Jakarta. The study was conducted from December 2011 – February 2012. The data were collected in a retrospective way for a year (January – December 2011. End-stage CRF patients who were having hemodialysis therapy and receiving ACE Inhibitor drugs or Angiotensin II Receptor Antagonist (AIIRA and receiving treatment at the General Practice Rooms at Central Army Hospital Gatot Soebroto Jakarta. During the period of January – December 2011, 84 patients were treated with end-stage CRF at the Central Army Hospital and having routine hemodialysis and 44 patients were receiving therapy with ACE Inhibitor and AIIRA. Other drugs simultaneously given with ACE Inhibitor and AIIRA were captopril-spironolactone, captopril-aspirin, captopril-allopurinol, captopril-KSR, captopril-furosemide, lisinopril-furosemide and valsartan-mefenemic acid. An increase in adverse effects of the drugs was found based on the clinical evaluation and laboratory examination. The adverse effects included hyperkalemia (9,09%, decrease in anti-hypertension effect (6,8%, acute hypotension (40%, and declining renal function (11,36%. The study identifies drug interaction

    Full Text Available Abstract Background Recent research shows that the prevalence of patients with very severe chronic obstructive pulmonary disease (COPD, congestive heart failure (CHF and chronic renal failure (CRF continues to rise over the next years. Scientific studies concerning self-perceived symptoms and care needs in patients with severe to very severe COPD, CHF and CRF are scarce. Consequently, it will be difficult to develop an optimal patient-centred palliative care program for patients with end-stage COPD, CHF or CRF. The present study has been designed to assess the symptoms, care needs, end-of-life care treatment preferences and communication needs of patients with severe to very severe COPD, CHF or CRF. Additionally, family distress and care giving burden of relatives of these patients will be assessed. Methods/design A cross-sectional comparative and prospective longitudinal study in patients with end-stage COPD, CHF or CRF has been designed. Patients will be recruited by their treating physician specialist. Patients and their closest relatives will be visited at baseline and every 4 months after baseline for a period of 12 months. The following outcomes will be assessed during home visits: self-perceived symptoms and care needs; daily physical functioning; general health status; end-of-life care treatment preferences; end-of-life care communication and care-giver burden of family caregivers. Additionally, end-of-life care communication and prognosis of survival will be assessed with the physician primarily responsible for the management of the chronic organ failure. Finally, if patients decease during the study period, the baseline preferences with regard to life-sustaining treatments will be compared with the real end-of-life care. Discussion To date, the symptoms, care needs, caregiver burden, end-of-life care treatment preferences and communication needs of patients with very severe COPD, CHF or CRF remain unknown. The present study will

    2001-01-01

    Objective: To explore the protective effect of Baoyuan Qiangshen Capsule No. Ⅱ (BYQS) and its mechanism in treating chronic renal failure (CRF). Methods: Sixty CRF patients were divided into 2 groups randomly, the treated group used BYQS combined with Lotensin and the control group administered with essential amino acid combined with Lotensin. Changes of renal functions and tubular labelled proteins were observed. Results: The markedly effective rate and total effective rate of the treated group were 63.3% and 93.3% respectively, and those of the control group were 30.0% and 56.7% respectively, the effect of the treated group was obviously better than that of the control group (P<0.01). In the treated group after medication, blood urea nitrogen, serum creatinine and clearance rate of creatinine were improved significantly (P<0.01), while Tamm-Horfau protein increased significantly (P<0.01). Conclusion: BYQS could alleviate tubular interstitial injury significantly so as to improve the renal function and enhance the effective rate in treating CRF.

    Review of the literature concerning contrast-induced renal dysfunction shows that the currently used agents are remarkably safe with careful patient selection. Clinically apparent kidney failure after their use is essentially nonexistent in those without preexistent renal insufficiency. The incidence rises rapidly in those with azotemia from any cause, however, and diabetic persons with nephropathy are perhaps at special risk. Vigorous volume expansion is possibly effective as a preventive measure and may attenuate adverse effects in those in whom postcontrast dysfunction occurs. New agents are becoming available. It is not yet known if these will prove safer or cost-effective. They have some experimentally demonstrated and theoretical advantages over the presently used agents. 58 references, 1 figure, 2 tables.

    Hospitalizations due to heart failure are increasing steadily despite advances in medicine. Patients hospitalized for worsening heart failure have high mortality in hospital and within the months following discharge. Kidney dysfunction is associated with adverse outcomes in heart failure patients. Recent evidence suggests that both deterioration in kidney function and renal congestion are important prognostic factors in heart failure. Kidney congestion in heart failure results from low cardiac output (forward failure), tubuloglomerular feedback, increased intra-abdominal pressure or increased venous pressure. Regardless of the cause, renal congestion is associated with increased morbidity and mortality in heart failure. The impact on outcomes of renal decongestion strategies that do not compromise renal function should be explored in heart failure. These studies require novel diagnostic markers that identify early renal damage and renal congestion and allow monitoring of treatment responses in order to avoid severe worsening of renal function. In addition, there is an unmet need regarding evidence-based therapeutic management of renal congestion and worsening renal function. In the present review, we summarize the mechanisms, diagnosis, outcomes, prognostic markers and treatment options of renal congestion in heart failure.

  4. Acute renal failure due to rhabdomyolyisis

    Directory of Open Access Journals (Sweden)

    Nieto-Ríos, John Fredy

    2016-04-01

    Full Text Available Acute renal failure is a frequent cause of morbidity and mortality in emergency, hospitalization and critical care services. In 15 % of cases it is due to rhabdomyolysis, in which there is breakdown of skeletal muscle with massive necrosis and leakage of muscle cell contents into the circulation. It has many different etiologies. The rhabdomyolysis-induced acute kidney injury results from the combination of several mechanisms, including tubular obstruction, vasoconstriction and oxidative stress. The most important therapeutic measures are: Aggressive repletion of fluids, forced diuresis and avoidance of exposure to nephrotoxic substances. In cases of severe uremia, metabolic acidosis, hiperkalemia or fluid overload it is necessary to start renal replacement therapy. As a rule, kidney function is completely recovered, but these patients have higher risk of future chronic kidney disease.

    Toll-like receptor 4 (TLR4) signaling is involved in various acute and chronic renal lesions and contributes to inflammation and fibrosis in several organs; the latter are important determinants to the progression of chronic kidney disease (CKD). We aimed to assess TLR4 expression in progressive CKD and relate it to severity of kidney damage, using an experimental nephron reduction model. Male Wistar rats were subjected to subtotal nephrectomy using the ligation technique, after 12 weeks of observation, serum creatinine and proteinuria were determined, animals were sacrificed, glomerulosclerosis and interstitial scarring were quantified histologically, and TLR4 expression was assessed by immunohistochemistry. Sham-operated rats served as controls. Case animals had significantly higher creatinine, proteinuria, glomerulosclerosis and tubulointerstitial involvement. TLR4 expression was prominent in proximal tubes, less staining was observed on infiltrating inflammatory cells. Percentage of TLR4-positive tubes was reduced in the subtotal nephrectomy animals, when compared to controls (0.67±0.09 versus 0.79±0.07, p=0.003). Percentage of TLR4-positive tubes correlated inversely to markers of kidney damage: to proteinuria (r=-0.55, p=0.02), serum creatinine (r=-0.53, p=0.01); percentage of glomeruli with glomerulosclerosis (r=-0.54, p=0.01) and tubulointerstitial score (r=-0.36, p=0.01). As TLR4 staining appears in tubular casts only in nephrectomy animals, shedding from damaged tubular cells is a very likely explanation for the reduced TLR4 expression in the kidneys of subjects with experimental nephron reduction.

    Full Text Available The aim of the study was to evaluate hemodynamics, endothelium function of kidneys and platelets depending on the body mass index (BMI in patients with chronic heart failure (CHF and preserved systolic function. 42 patients (mean age - 76,690,83 years with CHF II-III FC NYHA with preserved systolic function (LVEF>45% were enrolled. Echocardiography was performed, endothelial function, serum creatinine levels and microalbuminuria were determined in patients. BMI and glomerulation filtration rate were calculated by formulas. The morphological and functional status of platelets was estimated by electronic microscopy. It was defined that increased BMI in patients with CHF and preserved systolic function determines the structural and functional changes of the myocardium and leads to the endothelial and renal functional changes. An increased risk of thrombogenesis was established in patients with overweight and obesity.

    Full Text Available : Patients presenting for an elective or emergency surgery with pre-existing chronic renal failure (CRF has certain anesthetic considerations. Central neuraxial block for these patients is controversial, because all these patients will be invariably on fluid restriction. If such patient presents with pulmonary complications and cardiac complications which are relative contraindications for general anesthesia then the anesthetic management becomes trickier. We had a patient with CRF, presented with inter-trochanteric fracture of femur for surgical fixation. The patient also had left side loculated pneumothorax, right side bronchiectatic changes and permanent cardiac pacemaker for complete heart block which were challenges for general anesthesia too. Finally the surgery was done under central neuraxial block with dopamine support successfully.

    aspiration. The possibility that uremic patients present delayed gastric emptying is fascinating. Gastric complaints are common in this patient population, and could be explained by the difficulty to empty the stomach. Despite the evidence, there is controversy in the literature regarding this subject. There is no consensus regarding the results. Differences in the methods of the studies could explain the results obtained in clinical and experimental trials. The objective of this study was to review a few important aspects of the dyspeptic syndrome in patients with chronic renal failure (CRF, emphasizing the delayed GE. CONTENTS: The basic aspects of the physiology of GE, methods used more often to study GE, dyspeptic syndrome and uremia, and gastric emptying in chronic renal failure will be discussed. CONCLUSIONS: Gastric emptying is a complex physiological process that transfers food from the stomach to the duodenum, whose mechanisms are yet to be fully characterized. Scintigraphy, using meals with radiolabelled drugs, is the exam used more often to study GE. An expressive percentage of the patients with end-stage renal disease also present delayed GE. It is possible that other mechanisms, besides uremia, involved in gastric motor function also play a role in this dysfunction.

    Introduction Anemia associated with chronic kidney disease is a serious complication necessitating expenditure of huge medical efforts and resources. 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-α (TNF-α), 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-α, 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. PMID:24023521

    Full Text Available A miringoesclerose é uma alteração cicatricial da lâmina própria da membrana timpânica caracterizada por proliferação de fibras colágenas, seguida de hialinização, deposição de cálcio e fósforo, seguindo uma seqüência semelhante ao que ocorre em outros tipos de calcificação patológica comuns em pacientes com doença renal crônica. OBJETIVO: Verificar a influencia da insuficiência renal crônica (IRC na prevalência da miringoesclerose. MÉTODO: Foi realizada otoscopia em 341 pacientes com IRC em hemodiálise e em 356 indivíduos de um grupo controle. Foi comparada a freqüência de otoscopia positiva entre os dois grupos, procurando-se relacionar com variáveis pessoais e relacionadas a IRC. RESULTADOS: O grupo de pacientes apresentou 11,7% de otoscopia positiva contra 5,1% do grupo controle. Não houve influência do sexo ou cor na freqüência da miringoesclerose. Porém, os grupos foram heterogêneos em relação à faixa etária. Também não houve diferença importante no tempo de diálise nem nos níveis séricos de minerais e do PTH entre os pacientes do grupo de estudo que apresentavam otoscopia positiva ou negativa. CONCLUSÃO: Os achados, embora apontem para uma maior ocorrência da miringoesclerose nos pacientes renais crônicos, não nos permitem concluir com certeza que exista alguma relação entre a IRC e as alterações timpânicas.Myringosclerosis is a scar of the tympanic membrane lamina propria, resulting from trauma or inflammation, characterized by proliferation of collagen, hyalinization, calcium and phosphate deposits and cartilaginous or osseous metaplasia of the middle ear mucosa, a sequence that is similar to that taking place in other types of pathologic calcification, common in chronic renal failure (CRF.

    Full Text Available A insuficiência renal crônica é doença de elevada morbidade e mortalidade e sua incidência e prevalência em estágio terminal têm aumentado progressivamente a cada ano. Segundo a Sociedade Brasileira de Nefrologia, as principais causas de insuficiência renal crônica são hipertensão arterial, glomerulonefrite e diabetes mellitus. Diversos fatores elevam o risco de mortalidade em pacientes com nefropatia crônica, principalmente idade, presença de diabetes e número de comorbidades associadas. Para pacientes com menos de 50 anos de idade a taxa de sobrevida em 5 anos é de 62% e para aqueles acima desta idade e com diagnóstico de diabetes mellitus a sobrevida é de apenas 23%. A carambola, fruta originária da Ásia e muito difundida na maioria dos países tropicais, tem sido reportada como contendo uma neurotoxina capaz de provocar graves alterações neurológicas em pacientes com histórico de nefropatia crônica. Dentre estas alterações podemos observar desde quadros leves, como soluços e confusão mental, até quadros mais sérios, como convulsões e morte. Essa neurotoxina parece apresentar especificamente inibição sobre o sistema de condução GABAérgico. Descrevemos o caso de um paciente nefropata crônico que, após ingestão de carambola, inicia quadro de mal-estar, náuseas e vômitos, seguidos de episódios convulsivos reentrantes e vai a óbito mesmo com o tratamento hemodialítico convencional.Chronic renal failure is a high morbidity and mortality condition, with its terminal phase incidence and prevalence steadily growing year after year. According to the Sociedade Brasileira de Nefrologia [Brazilian Society of Nephrology], the main causes of renal failure are arterial hypertension, glomerulonephritis and diabetes mellitus.

    Full Text Available Lanthanum carbonate (LA is an effective phosphate binder. Previous study showed the phosphate-binding potency of LA was twice that of calcium carbonate (CA. No study in which LA and CA were given at an equivalent phosphate-binding potency to rats or humans with chronic renal failure for a long period has been reported to date. The objective of this study was to compare the phosphate level in serum and urine and suppression of renal deterioration during long-term LA and CA treatment when they were given at an equivalent phosphate-binding potency in rats with adriamycin (ADR-induced nephropathy. Rats were divided into three groups: an untreated group (ADR group, a CA-treated (ADR-CA group and a LA-treated (ADR-LA group. The daily oral dose of LA was 1.0 g/kg/day and CA was 2.0 g/kg/day for 24 weeks. The serum phosphate was lower in the ADR-CA or ADR-LA group than in the ADR group and significantly lower in the ADR-CA group than in the ADR group at each point, but there were no significant differences between the ADR and ADR-LA groups. The serum phosphate was also lower in the ADR-CA group than in the ADR-LA group, and there was significant difference at week 8. The urinary phosphate was significantly lower in the ADR-CA group than in the ADR or ADR-LA group at each point. The urinary phosphate was also lower in the ADR-LA group than in the ADR group at each point, and significant difference at week 8. There were no significant differences in the serum creatinine or blood urea nitrogen among the three groups. In conclusion, this study indicated the phosphate-binding potency of LA isn't twice as strong as CA, and neither LA nor CA suppressed the progression of chronic renal failure in the serum creatinine and blood urea nitrogen, compared to the untreated group.

  19. Nutrition in acute renal failure

    Sérgio Mussi Guimarães

    Full Text Available Nutritional status has been considered to be one of the possible determinants of mortality rates in cases of acute renal failure (ARF. However, most studies evaluating possible mortality indicators in ARF cases have not focused on the nutritional status, possibly because of the difficulties involved in assessing the nutritional status of critically ill patients. Although the traditional methods for assessing nutritional status are used for ARF patients, they are not the best choice in this population. The use of nutritional support for these patients has produced conflicting results regarding morbidity and mortality. This review covers the mechanisms and indicators of malnutrition in ARF cases and the types of nutritional support that may be used.

    Chronic renal failure (CRF) is a widespread medical problem commonly accompanied by a hypoproliferative anemia ("renal anemia") due to erythropoietin deficiency. Anemia greatly contributes to reduced quality of life (Hr-QoL) and high morbidity and mortality in CRF patients. Recombinant human erythropoietin (rHu-Epo) was introduced to medical practice some 20years ago. It enables correction of anemia (hemoglobin levels, Hb) with dramatic immediate (Hr-QoL improvement) and long-term effects (reduced morbidity and mortality). Newer experimental data suggest that long-term benefits could be due not only to antianemic effect, but also to a direct organoprotective effect of (rHu)-Epo mediated through a receptor complex different from the "erythropoietic" erythropoietin receptor. During the last decade, two alternative treatments for renal anemia have been approved: darbepoetin and CERA. Both are direct agonists of the "erythropoietic" receptors and both were derived from rHu-Epo. Molecularly, they differ from rHu-Epo in that they are much larger molecules (darbepoetin is genetically modified rHu-Epo with a higher sugar content and CERA is pegylated rHu-Epo) with lower affinity for the erythropoietin receptor but with a longer circulating time. In terms of renal anemia correction, they are non-inferior to rHu-Epo and allow for less frequent dosing. They have never been compared to rHu-Epo regarding the long-term outcomes. It is hypothesized that regarding the long-term outcomes (morbidity, mortality), rHu-Epo might be superior to those larger molecules. The hypothesis is based on two types of observations. First, experimental data emphasize the role of small, erythropoietically less valuable rHu-Epo isoforms in its organoprotective effects. Second, clinical observations suggest that rHu-Epo enables for less variable Hb correction than the larger molecules, and pronounced within-subject Hb variability has been suggested as an independent predictor of poor long

    Biocompatible dialysis solutions have been developed to preserve peritoneal membrane morphology and function. Compared with a conventional solution, a combination of glycerol, amino acids, and dextrose in a bicarbonate/lactate buffer (GLAD) led to less peritoneal fibrosis and fewer vessels in a chronic peritoneal exposure model in the rat. However, no concomitant reduction in small-solute transport was observed. We hypothesized that this result could be attributable to peritoneal vasodilation induced by vasoactive substances such as nitric oxide. The aim of the present study was to investigate whether fast transport of small solutes and proteins induced by exposure to GLAD could be influenced by Ngamma -methyl-L-arginine acetate (L-NMMA), an inhibitor of NO. These investigations used our rat model of long-term peritoneal exposure with chronic renal failure. All rats underwent peritoneal catheter implantation and a 70% nephrectomy. Thereafter, the rats were allocated to 3 groups: 16 weeks of peritoneal exposure to GLAD and L-NMMA, to GLAD only, or to buffer (bicarbonate/lactate without any osmotic agent). Afterward, a standard peritoneal permeability analysis adjusted for the rat was performed. Subsequently, the rats were euthanized, and tissue samples were obtained for morphometric determinations. No effect of L-MNNA on the transport of small solutes and proteins was found. Also, no effect on morphology was found. Our findings make it unlikely that NO is directly involved, being more in favor of a direct effect of amino acids on peritoneal transport.

    Renal replacement therapy became a common clinical tool to treat patients with severe acute kidney injury (AKI) since the 1960s. During this time dialytic options have expanded considerably; biocompatible membranes, bicarbonate dialysate and dialysis machines with volumetric ultrafiltration control have improved the treatment for acute kidney injury. Along with advances in methods of intermittent hemodialysis, continuous renal replacement therapies have gained widespread acceptance in the treatment of dialysis-requiring AKI. However, many of the fundamental aspects of the renal replacement treatment such as indication, timing of dialytic intervention, and choice of dialysis modality are still controversial and may influence AKI patient's outcomes. This review outlines current concepts in the use of dialysis techniques for AKI and suggests an approach for selecting the optimal method of renal replacement therapy.

    Full Text Available Renal failure is the loss of renal function, either acute or chronic, that results in azotemia and syndrome of uremia. Acute renal failure, is also known as acute kidney injury (AKI, is defined as an abrupt (within 48 hours reduction in kidney function. The initial management of acute kidney failure involves treating the underlying cause, stopping nephrotoxic drugs and ensuring that the patient is euvolaemic with an adequate mean arterial blood pressure. However, no specific treatments have been shown to reverse the course AKF so Renal Replacement Therapy (RRT is the cornerstone of further management. RRT therapy can be administrated either intermittently or continuously. Multiple modalities of RRT are currently available. The purpose of this review is to familiarize different modalities of RRT for blood purification.

    Ischemic and toxic acute renal failure is reversible, due to the ability of renal tubule cells to regenerate and differentiate into a fully functional lining epithelium. Recent data support the thesis that recruitment or activation of macrophages to the area of injury results in local release of growth factors to promote regenerative repair. Because of intrinsic delay in the recruitment of inflammatory cells, the exogenous administration of growth promoters early in the repair phase of acute renal failure enhances renal tubule cell regeneration and accelerates renal functional recovery in animal models of acute renal failure. Molecular therapy for the acceleration of tissue repair in this disease process may be developed in the near future.

    We report a patient with neuroleptic malignant syndrome (NMS) who developed acute renal failure and was successfully treated by hemodialysis. A 60-year-old man with a 26-year history of schizophrenia had been treated with thioridazine and sulpiride. He was admitted to our hospital for muscular rigidity and oliguria. After the diagnosis of NMS with acute renal failure was established, thioridazine and sulpiride were discontinued and hemodialysis was instituted. Renal function gradually improved and hemodialysis was discontinued after 17th treatment. We also reviewed 57 cases of NMS with acute renal failure reported in the literature. To our knowledge, 26 years is the longest latency between initiation of neuroleptic drug treatment and onset of NMS. Our review of reported NMS cases with acute renal failure identified those risks for poor prognosis as high level of BUN, age and female gender.

    Objective To investigate the common etiologies and their differences in patients with chronic renal failure (CRF) ,thus allowing for guidance of the prevention and treatment. Methods We did a retrospective review on the etiologies of CRF in 937 adults who were treated with hemodialysis and peritoneal dialysis in the in-patient or out-patient clinics, Fourth Affiliated Hospital of China Medical University,between January 2006 and December 2010,for determination of the etiologic features. Results The five leading etiologies of CRF were as follows:chronic glomerulonephritis (26. 15% ) ,diabetic nephropathy (25. 51% ) ,chronic interstitial nephritis (19.64% ) ,hypertensive renal impairment (14. 41% ) and obstructive nephropathy (5. 23% ). The distribution of etiologies varied considerably in different age groups and CKD stages. Our results showed that diabetic nephropathy was the leading cause of CRF in patients aged over 60 years and those at stages CKD3/CKD4 (26. 54% and 27. 57% ,respectively). Whereas chronic glomerulonephritis was the most common etiology of CRF in patients aged less than 59 years and those at stage CKD5 (43. 06% and 29. 84% ,respectively). Conclusion Chronic glomerulonephritis retains its first ranking in the etiology yet incidence of diabetic nephropathy is approaching. In patients with CRF aged over 60 years and those at stages CKD3/CKD4,diabetic nephropathy has become the leading etiology, followed by interstitial nephritis, hypertensive renal impairment and chronic obstructive nephropathy.%目的 探讨慢性肾功能衰竭(CRF)的常见病因并分析其病因变化,为指导CRF的病因诊断和正确防治提供依据.方法 回顾性分析2006年9月至2011年12月在中国医科大学附属第四医院住院、门诊、血液净化中心透析、腹膜透析的937例患者的CRF病因,了解其病因特点.结果 CRF患者的病因构成前5位依次为慢性肾小球肾炎(26.15%)、糖尿病肾病(25.51%)、慢性间质性肾炎(19

    Burn care providers are usually challenged by multiple complications during the management of acute burns. One of the most common complications worldwide is renal failure. This article reviews the various aspects of renal failure management in burn patients. Two different types of renal failures develop in these patients. The different aetiological factors, incidence, suspected prognosis, ways of diagnosing, as well as prevention methods, and the most accepted treatment modalities are all discussed. A good understanding and an effective assessment of the problem help to reduce both morbidity and mortality in burn management.

    Full Text Available Objective: To estimate the underlying primary diseases of chronic renal failure (CRF among patients attending Al-Thawra General Hospital, Sana'a, and Yemen. Methods: This was a cross-sectional, hospital-based study of 566 patients diagnosed with chronic kidney diseases (CKD. It studied the cases attending Al-Thawra General Hospital over a three‐year period from January 2013 to De-cember 2015. Results: Out of 566 patients, 339 (59.9% were males. The mean age of the patients at diagnosis of CKD was 39.51 years, most of whom (36.6% were of the age group of 21–35 years. Hypertension was the most frequent cause (43.2% of CRF, followed by different infectious diseases such as malaria, schistosomiasis and bacterial infections (19% and obstructive nephropathy (17.9%. On the other hand, CRF of unknown etiology represented 15.2% of cases. Other causes of CRF diabetic nephropathy (9.7%, effect of antibiotics and analgesics (7.0%, ischemic heart disease (4.8%, polycystic kidney disease (3.5% and congenital anomalies (3.4%. The least common causes were autoimmune diseases, bleeding, traumatic accidents and chronic diarrhea, being responsible for 2.2%, 1.8%, 0.9% and 0.4% of CRF cases, respectively. Conclusions: The majority of CKD cases in our study were males aged between 21 and 35 years old. In addition, most cases of CKD are due to hypertension, followed by infections and obstructive nephropathy. Application of future prevention and control measures are highly recommended to reduce the burden of CRF in Yemen for early detection and proper management of its underlying primary conditions/diseases.

  1. Diagnosing vascular causes of renal failure.

    Science.gov (United States)

    Abuelo, J G

    1995-10-15

    The incidence of renal failure due to vascular diseases is increasing. Two reasons for this are the epidemic of atherosclerotic vascular disease in the aging population and the widespread use of vasoactive drugs that can adversely affect renal function. These vascular causes of renal failure include vasomotor disorders such as that associated with nonsteroidal antiinflammatory drugs, small-vessel diseases such as cholesterol crystal embolization, and large-vessel diseases such as renal artery stenosis. These causes of azotemia are less familiar to physicians than more classic causes, such as acute tubular necrosis, and are less likely to be recognized in their early stages. This article describes the various vascular diseases that impair renal function and outlines the steps necessary to identify them. Although some of these conditions, such as renal artery stenosis, can gradually impair function, the vascular causes of acute renal failure are emphasized in this article. Because the vasculitides primarily cause renal failure through secondary glomerulonephritis, they are mentioned only briefly. Extensive testing is rarely necessary because the cause is usually suspected through syndrome recognition. The diagnosis can then be confirmed by the results of one or two additional tests or by improved renal function after treatment.

    Conclusion Circulating angiopoietin-2 is a putative marker and potential mediator of atherosclerosis, is inversely related to glomerular filtration rate, and is increased with advanced chronic kidney disease. Normolipidemia in chronic kidney disease patients does not prevent atherosclerotic burden; this is because of the presence of other markers such as angiopoietin-2.

    Heat inactivation has been proposed as an alternative to perchloric acid (PCA) precipitation for the extraction of carcinoembryonic antigen (CEA) from human plasma. A commercial RIA kit using heat inactivation was examined and results compared with those obtained with PCA precipitation. Adequate sensitivity (1.5 ..mu..g CEA/I plasma), satisfactory analytical recovery of CEA added to plasma, and dilutional linearity of samples found to have elevated CEA concentrations, were demonstrated for the heat-inactivation assay. Between-assay precision was better with the heat inactivation than with the PCA assay. Although the absolute concentration of CEA estimated after heat inactivation was consistently lower than that estimated after PCA extraction of plasma specimens, there was excellent correlation between results obtained with the two methods in colon cancer patients free of disease, colon cancer patients with residual or recurrent disease, patients with benign gastrointestinal disease, and in patients with chronic renal failure. The heat-inactivation assay is an excellent alternative to the PCA assay.

We examined a commercial RIA kit using heat inactivation, and compared results with those obtained with PCA precipitation. Adequate sensitivity (1.5 micrograms CEA/l plasma), satisfactory analytical recovery of CEA added to plasma, and dilutional linearity of samples found to have elevated CEA concentrations, were demonstrated for the heat-inactivation assay. Between-assay precision was better with the heat inactivation than with the PCA assay. Although the absolute concentration of CEA estimated after heat inactivation was consistently lower than that estimated after PCA extraction of plasma specimens, there was excellent correlation between results obtained with the two methods in colon cancer patients free of disease, colon cancer patients with residual or recurrent disease, patients with benign gastrointestinal disease, and in patients with chronic renal failure.

    Using electron spin resonance (ESR) spin labeling technique,we have studied the conformation of sulfhydryl groups(-SH) binding sites in membrane proteins and mem brane fluidity of red blood cells(RBCs) from two groups of patients with anemia of chronic renal failure(ACRF).One of the groups is composed of patients who were untreated with recombinant human erythropoietin(r-HuEPO),and the other is composed of patients who were treated with r-HuEPO.The results indicated:1)the conformation of SH group binding site in RBC membrane proteins from former group was different from those of healty people.2)the fluidity in the region near the surface of RBC membrane from former group was lower than those of healthy people.3)However,the above biophysical properties of RBC membrane from later group were normal.We concluded that RBC membrane in patients with ACRF was abnormal,and the treatment of r-HuEPO may promote the production of normal RBCs,thus ameliorate the biophysical properties of RBCs from the patients with ACRF.

    Objective: To investigate the effect of Chinese drugs (CD) that invigorate Spleen to remove Dampness and activate the blood circulation to eliminate Turbid for retarding progression of chronic renal failure (CRF). Methods: Thirty-nine patients with CRF were divided into two groups at random: the 18 patients in group A (the control group) were treated with low protein diet and controlling blood pressure and 21 patients in group B (the treatment group) were treated similarly with that of the control group and additional CD. Levels of serous creatinine (SCr), blood urea nitrogen (BUN), blood albumin (Alb), total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL) and hemoglobin (Hb) were checked every two months and the rate of progression of CRF was estimated by slope of the creatinine reciprocal (1/SCr) with time (months). Results: Levels of SCr and BUN in group B were lower and HDL higher than those in group A significantly, P<0.05. Mean slopes of the creatinine reciprocal with time in the two groups were markedly different, P<0.01. Conclusion: Additional CD treatment based upon the low protein diet and controlling blood pressure could retard the rate of progression of CRF evidently.

    Omeprazole is a proton pump inhibitor widely used in the treatment of gastro-esophageal reflux disease and peptic ulcer disease. In a 73-year-old man we describe renal failure due to acute interstitial nephritis after use of omeprazol during 4 months. Unexpected renal failure without signs of hydronephrosis should always provoke awareness of drug reaction, omeprazole being one of the possible drugs.

    Background Chronic renal failure (CRF) predisposes to hip fractures in elderly patients, with high subsequent mortality. Selection and timing of the surgical procedure of such patients is a serious challenge. Many clinicians believe in earlier surgery as preferable and providing better outcomes. Damage control orthopedics (DCO) aids to adjust and optimize the overall condition of patients. Methods In 32 patients with femoral neck fractures complicated with CRF, we evaluated how the timing of the surgery determines the mortality rates if the DCO approach is applied. Preoperative ASA grading, POSSUM score, P-POSSUM score and DCO were carried out. Based on the assessment, timing of the surgery was ascertained. Results Of a total of 32 patients, twenty-nine patients were accepted for either early (< 48 hours; n = 18) or delayed (3–10 days; n = 10) surgery. Hip arthroplasty (total hip arthroplasty and hemiarthroplasty) was the principal surgery option. All patients survived operation and were followed up postoperatively with the average time of 30 days. Postoperative complications tended to occur at higher rates in the early vs. delayed surgery group (7/18 vs. 5/10). During follow up, a total of 3 patients died in both groups (2/18 in the early surgery and 1/10 in the delayed surgery group), mostly from multi-organ failures and acute respiratory distress syndrome. There was no significant difference in complication rates and Harris hip score between both groups. Conclusion In patients with femoral neck fracture complicated with CRF, delaying the surgery for several days does not increase the incidence of postoperative adverse events. PMID:27149117

    A previously healthy young man presented with acute renal failure due to extensive spontaneous deep vein thrombosis, including the inferior vena cava (IVC) and both renal veins. The patient was treated with selectively delivered thrombolytic therapy over a 7-day-period, which resulted in renal vein patency and complete recovery of renal function. A stent was placed over a segment stenosis of the IVC. No thrombophilic factors were identified. Bilateral renal vein thrombosis in young fit individuals is an unusual cause of acute renal failure. Thrombolytic therapy, even with delay, can completely restore renal function.
