    Patients who have both atrial fibrillation (AF) and renal failure have an increased risk of thrombo-embolism. Renal failure is also a risk factor for bleeding, which makes decisions regarding thromboprophylaxis complicated. Our aim was to determine risks for ischaemic stroke and bleeding in patients with AF and renal failure in relation to anticoagulant strategies. This is retrospective non-randomized study of Swedish health registers comprising 307 351 patients with AF, of whom 13 435 had a previous diagnosis of renal failure. Ischaemic stroke occurred more often in AF patients with renal failure (annual rate, 3.9% vs. no renal failure, 2.9%), but this was related to concomitant comorbidities [adjusted hazard ratio (HR) 1.02, 95% confidence interval (CI) 0.95-1.10]. Adding renal failure to the established stroke risk stratification schemes (CHADS2 and CHA2DS2-VASc) did not improve their predictive value. Renal failure was an independent risk factor for intracranial bleeding [adjusted HR: 1.27 (1.09-1.49)]. Most patients with renal failure benefited from warfarin treatment, despite their high bleeding risk. The incidence of the combined endpoint ischaemic or haemorrhagic stroke or death was lower among those who used warfarin than among those who did not use warfarin (adjusted HR: 0.76, CI 0.72-0.80). Patients with both AF and renal failure will probably benefit most from having the same treatment as is recommended for other patients with AF, without setting a higher or lower threshold for treatment. Adding additional points for renal failure to the CHADS2 and CHA2DS2-VASc scores did not improve their predictive value. Published on behalf of the European Society of Cardiology.

    This book covers most aspects of imaging studies in patients with renal failure. The initial chapter provides basic information on contrast agents, intravenous urography, and imaging findings in the urinary tract disorders responsible for renal failure and in patients who have undergone transplantation. It illustrates common gastro-intestinal abnormalities seen on barium studies in patients with renal failure. It illustrates the cardiopulmonary complications of renal failure and offers advice for radiologic differentiation. It details different aspects of skeletal changes in renal failure, including a basic description of the pathophysiology of the changes; many excellent illustrations of classic bone changes, arthritis, avascular necrosis, and soft-tissue calcifications; and details of bone mineral analysis

    Renal impairment is a common complication of multiple myeloma. Chronic renal failure is classified according to glomerular filtration rate as estimated by the MDRD (modification of diet in renal disease) formula, while RIFLE (risk, injury, failure, loss and end-stage renal disease) and AKIN (acute renal injury network) criteria may be used for the definition of the severity of acute renal injury. Novel criteria based on estimated glomerular filtration rate measurements are proposed for the definition of the reversibility of renal impairment. Renal complete response (CRrenal) is defined as sustained (i.e., lasting at least 2 months) improvement of creatinine clearance (CRCL) from under 50 mL/min at baseline to 60 mL/min or above. Renal partial response (PRrenal) is defined as sustained improvement of CRCL from under 15 mL/min at baseline to 30 to 59 mL/min. Renal minor response (MRrenal) is defined as sustained improvement of the baseline CRCL of under 15 mL/min to 15 to 29 mL/min or, if baseline CRCL was 15 to 29 mL/min, improvement to 30 to 59 mL/min. Bortezomib with high-dose dexamethasone is considered the treatment of choice for myeloma patients with renal impairment and improves renal function in most patients. Although there is limited experience with thalidomide, this agent can be administered at the standard dosage to patients with renal failure. Lenalidomide, when administered at reduced doses according to renal function, is effective and can reverse renal impairment in a subset of myeloma patients.

    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.

    Acute renal failure (ARF) may be due to obstructive uropathy or renal parenchymal disease. Twenty-five children with acute renal failure secondary to renal parenchymal disease underwent ultrasonographic examination of the kidneys. Changes of renal size and cortical echogenicity were correlated with renal function. All patients presented with bilaterally enlarged kidneys with the exception in renal function resulted in normalization of renal size. With regard to cortical echogenicity two groups were formed. Group A comprised 11 patients whose kidneys had the same echogenicity as the liver, while in group B the kidneys were more echogenic (14 patients). Cortical echogenicity was always increased. Determination of creatinine levels showed a statistically significant difference between group A (3.32 mg% ± 1.40 S.D.) and group B (5.95 mg% ± 1.96 S.D.), p < 0.001. Changes in renal function were paralleled by rapid changes in renal size and cortical echogenicity. (orig.)

    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.

    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.

    Acute renal failure is a serious complication oif reconstructive aortoiliac surgery. The question was raised whether its etiology includes interaction between preoperative angiographic contrast medium and intra-operative clamping of the renal arteries. Renal arteries of 180 rats were bilaterally clamped 10 to 120 min and serum urea was determined from 3 h to 7 days later. In 35 rats 40 min clamping alone produced an increase in urea reaching a maximum 1 day later (median increase 70%). In 3 groups of 12 rats intravenous injection of the contrast medium metrizoate alone in doses 1, 2 and 3 g I/kg body-weight produced no significant increase in urea. Intravenous injection of the same doses to 3 groups of 10 rats each followed 1 h later by renal arterial occlusion for 40 min produced median urea increases one day later of 110, 130 and 170%, respectively, in the 3 groups. The increase was higher than that produced by contrast medium alone (p<0.01) or by renal artery clamping alone (p<0.05) indicating a potentiation of transient renal failure by the combination of contrast medium and renal arterial clamping.

    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.

    To study the effects of renal failure on bumetanide kinetics, the authors administered single intravenous doses of 1.0 mg/3.08 microCi 14 C-bumetanide to six healthy subjects and 22 patients with variable degrees of renal failure. The kinetics of 14 C-bumetanide and total 14 C were adequately described by a two-compartment open model in the control subjects and in the patients. The volume of the central compartment and the distribution t1/2 were of the same order in both groups, whereas the mean (+/- SE) volume at steady state was larger (22.1 +/- 1.6 and 16.9 +/- 1.0 L) and the elimination t1/2 was longer (1.9 +/- 0.2 and 1.4 +/- 0.1 hours) in patients with renal failure than in healthy controls. Bumetanide renal clearance was lower (10 +/- 3 and 90 +/- 13 ml/min) in patients than in subjects and correlated with creatinine clearance (r = 0.784) and log serum creatinine level (r = -0.843), whereas nonrenal clearance was significantly higher in the patients (153 +/- 14 and 99 +/- 6 ml/min). Bumetanide total plasma clearance did not significantly change. The non-protein-bound, free fraction of bumetanide was higher in patients and correlated with plasma albumin levels (r = -0.777). The kinetics of total 14 C showed similar but greater changes than those of 14C-bumetanide. Thus the most important changes in bumetanide kinetics in patients with renal failure are low renal clearance and a high free fraction, with a consequent increase in nonrenal clearance, volume of distribution, and elimination t1/2

    The prevalence of both hypogonadism and renal failure is increasing. 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.

    It was demonstrated in rats that renal injury which follows transient renal hypoxia is potentiated by the contrast media metrizoate, ioxaglate, iopamidol and iohexol. Intravenous injection of 1 g I/kg of all four media alone to 82 rats caused no significant increase in serum urea 1, 3 and 7 days later. The percentage increase of serum urea is given in median values and interquartile range (in parentheses). Bilateral renal arterial occlusion alone for 40 minutes in 42 rats increased serum urea one day later by 40% (20-130). Intravenous injection of the media followed in one hour by bilateral renal arterial occlusion for 40 minutes in 104 rats caused serum urea to increase one day later by 130% (70-350) after metrizoate, by 220% (50-380) after ioxaglate, by 290 % (60-420) after iopamidol and by 160% (50-330) after iohexol. There were no significant differences between the potentiating effects of the various media on ischemic renal failure. (orig.)

The aim of this study is to present long-term follow-up of JS patients with early progressive kidney disease. Methods. This is a retrospective study of pediatric patients with JS and CRF who were treated at the University Children’s Hospital between January 1980 and December 2014. The patients’ data were retrospectively reviewed from the medical records. Results. There were thirteen patients from 11 families, five girls and eight boys mean aged 4.3 years at the time of diagnosis. All of the patients had characteristic skeletal findings, retinal degeneration and an early onset of CRF at age range from 1.5 to 7 years. Five patients had neonatal respiratory distress and congenital liver fibrosis was diagnosed in five patients. One patient died due to complications of CRF, while others survived during follow-up of mean 11 years. IFT140 mutations were found in four genetically tested patients. Conclusion. The average incidence rate of JS with renal phenotype in Serbia was about 0.2 per one million of child population. Long-term survival of JS patients depends on renal replacement therapy, while skeletal dysplasia, growth failure, respiratory and eyes problems have impact on the patients’ quality of life.

    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.

    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.

  9. Nutrition in acute renal failure

    Directory of Open Access Journals (Sweden)

    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.

    Sixteen infants, 2 to 35 days of age, had acute renal failure, a diagnosis based on serum creatinine concentrations greater than 1.5 mg/dL for at least 24 hours. Eight infants were oliguric (urine flow less than 1.0 mL/kg/h) whereas the remainder were nonoliguric. To determine clinical parameters useful in prognosis, urine flow rate, duration of anuria, peak serum creatinine, urea (BUN) concentration, and nuclide uptake by scintigraphy were correlated with recovery. Nine infants had acute renal failure secondary to perinatal asphyxia, three had acute renal failure as a result of congenital cardiovascular disease, and four had major renal anomalies. Four oliguric patients died: three of renal failure and one of heart failure. All nonoliguric infants survived with mean follow-up serum creatinine concentration of 0.8 +/- 0.5 (SD) mg/dL whereas that of oliguric survivors was 0.6 +/- 0.3 mg/dL. Peak serum creatinine concentration did not differ between those patients who were dying and those recovering. All infants who were dying remained anuric at least four days and revealed no renal uptake of nuclide. Eleven survivors were anuric three days or less, and renal perfusion was detectable by scintigraphy in each case. However, the remaining survivor (with bilateral renal vein thrombosis) recovered after 15 days of anuria despite nonvisualization of kidneys by scintigraphy. In neonates with ischemic acute renal failure, lack of oliguria and the presence of identifiable renal uptake of nuclide suggest a favorable prognosis

    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.

    Renal failure is an important adverse effect of drug poisoning. Determining the prevalence and etiology of this serious side effect could help us find appropriate strategies for the prevention of renal failure in most affected patients. The present study is aimed to identify drugs that induce renal failure and also to find the prevalence of renal failure in patients referred to emergency departments with the chief complaint of drug poisoning, in order to plan better therapeutic strategies to minimize the mortality associated with drug poisoning induced renal failure. This cross-sectional study surveyed 1500 poisoned patients referred to the Emergency Department of Baharloo Hospital in Tehran during 2010. Demographic data including age and gender as well as clinical data including type of medication, duration of hospital stay, and presence of renal failure were recorded. Mann-Whitney U test and chi-squared statistics were used to analyze the results. A total number of 435 patients were poisoned with several drugs, 118 patients were intoxicated with sedative-hypnotic drugs, 279 patients were exposed to opium, and 478 patients were administered to other drugs. The method of intoxication included oral 84.3%, injective 9%, inhalation 4.3% and finally a combination of methods 2.3%. Laboratory results revealed that 134 cases had renal failure and 242 had rhabdomyolysis. The incidence of rhabdomyolysis and renal failure increased significantly with age, and also with time of admission to the hospital. Renal failure was reported in 25.1% of patients exposed to opium, vs. 18.2% of patients poisoned with aluminum phosphide, 16.7% of those with organophosphate, 8% with multiple drugs, 6.7% with alcohol, heavy metals and acids, and 1.7% with sedative hypnotics. Based on the findings of this study, there is a high probability of renal failure for patients poisoned with drugs such as opium, aluminum phosphide, and multiple drugs as well as the patients with delayed admission to

  17. Malignancy and chronic renal failure.

    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.

    Fifteen Marine recruits with acute heat stroke were examined for (1) predisposing factors, (2) blood coagulation disturbances, (3) renal function abnormalities, and (4) blood composition alterations. Epidemiologic data identified the following risk factors; previous residence in a temperate climate, first phase of training, fatigue, and strenuous exercise in hot, humid conditions. Results of blood coagulation studies disclosed an increase in prothrombin and partial thromboplastin times, with a decrease in platelet count, probably indicating a transient, low-grade consumptive process. Blood urea nitrogen and creatinine levels and creatinine clearance were normal. Only mild elevations of SGOT, SGPT, and lactic dehydrogenase levels were noted, and in combination with clinical observations, they argued against significant muscle damage. No deaths or instances of renal failure occurred.

    Suppression of the human immune system results in an increase in susceptibility to infection by various infectious agents. Conditions such as AIDS, organ transplantation and chronic renal insufficiency (CRI) are the most important cause of insufficient immune response against infections. Long term renal disorders result in uremia, which can suppress human immune system. Parasitic infections are one of the most important factors indicating the public health problems of the societies. These infections can be more hostile and life threatening in susceptible individuals than in the normal people. In these patients some parasitic infections such as blastocystiosis, cryptosporidiosis and toxoplasmosis have been reported to be more prevalent. This review aimed to give an overview about parasitic infections in patients with renal disorders.

    Renal function is one of the most consistent prognostic determinants in heart failure. The prognostic information it provides is independent of the ejection fraction and functional status. This article reviews the various renal function assessment measures, with special emphasis on the fact that the patient's clinical situation and response to the heart failure treatment should be considered for the correct interpretation of the results. Finally, we review the literature on the performance of tubular damage biomarkers. Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Medicina Interna (SEMI). All rights reserved.

    Our purpose is to discuss established risk factors in the development of acute renal failure and briefly overview clinical markers and preventive measures. Findings from the literature support the role of older age, diabetes, underlying renal insufficiency, and heart failure as predisposing factors for acute renal failure. Diabetics with baseline renal insufficiency represent the highest risk subgroup. An association between sepsis, hypovolemia, and acute renal failure is clear. Liver failure, rhabdomyolysis, and open-heart surgery (especially valve replacement) are clinical conditions potentially leading to acute renal failure. Increasing evidence shows that intraabdominal hypertension may contribute to the development of acute renal failure. Radiocontrast and antimicrobial agents are the most common causes of nephrotoxic acute renal failure. In terms of prevention, avoiding nephrotoxins when possible is certainly desirable; fluid therapy is an effective prevention measure in certain clinical circumstances. Supporting cardiac output, mean arterial pressure, and renal perfusion pressure are indicated to reduce the risk for acute renal failure. Nonionic, isoosmolar intravenous contrast should be used in high-risk patients. Although urine output and serum creatinine lack sensitivity and specificity in acute renal failure, they remain the most used parameters in clinical practice. There are identified risk factors of acute renal failure. Because acute renal failure is associated with a worsening outcome, particularly if occurring in critical illness and if severe enough to require renal replacement therapy, preventive measures should be part of appropriate management.

    Full Text Available Acute renal failure (ARF is defined as a rapid decrease in the glomerular filtration rate, occurring over a period of hours to days. The Science and Technology University Hospital, Sana′a, is a referral hospital that caters to patients from all parts of Yemen. The aim of this study is to have a deeper overview about the epidemiological status of ARF in Yemeni patients and to identify the major causes of ARF in this country. We studied 203 patients with ARF over a period of 24 months. We found that tropical infectious diseases constituted the major causes of ARF, seen in 45.3% of the patients. Malaria was the most important and dominant infectious disease causing ARF. Hypotension secondary to infection or cardiac failure was seen in 28.6% of the patients. Obstructive nephropathy due to urolithiasis or prostate enlargement was the cause of ARF in a small number of patients. ARF was a part of multi-organ failure in 19.7% of the patients, and was accompanied by a high mortality rate. Majority of the patients were managed conservatively, and only 39.9% required dialysis. Our study suggests that early detection of renal failure helps improve the outcome and return of renal function to normal. Mortality was high in patients with malaria and in those with associated hepatocellular failure.

    In Africa, the use of traditional herbal remedy is widespread. Acute renal failure (ARF) is one of the most serious complications. The use of herbal remedies (mostly orally) accounts for nearly 35% of all cases of acute renal failure in Africa. Development of renal failure following herbal vaginal pessary is rarely reported. In November 2003, a 35-year-old Nigerian female who is a petty trader and a primary school leaver with three children (all males) presented to us in the renal unit with oliguric ARF induced by herbal vaginal pessary. She had sought this alternative medicine in an attempt to have a female child as all her three children are males. Her condition was managed accordingly and required three sessions of hemodialysis. She started diuresing on the eighth day of admission. This case presentation highlights the potential tragedies of herbal preparation, of note, that herbal vaginal pessaries are as deleterious as the oral preparations, and that the dilemma of ignorance is still prevalent in our society.

    MR imaging of the kidney was performed in 6 patients with acute renal failure (ARF) secondary to rhabdomyolysis caused by snake bite (n = 4), crush injury (n = 1), and carbon monoxide poisoning (n = 1). A test for urine myoglobin was positive in all 6 patients and MR imaging was done 6 to 18 days after the causative event of the rhabdomyolysis. MR images in all 6 patients showed globular swelling of the kidneys, preserved corticomedullary contrast on T1-weighted images, and obliteration of corticomedullary contrast on T2-weighted images. Unlike other medical renal diseases in which corticomedullary contrast is lost on T1-weighted images, preservation of the corticomedullary contrast on T1-weighted MR images with globular renal swelling was a constant finding in patients with ARF secondary to rhabdomyolysis.

    2008-01-01

    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.

    Acute Renal Failure (RF) is a rare but well recognized complication of Dengue Infection (DI). There has been paucity of published data regarding renal involvement in DI. The aim of the present study was to elucidate different clinical presentations, disease outcomes of DI. To study the frequency, severity and predictors of RF in DI. Patients diagnosed either as Dengue Fever (DF) or Dengue Haemorrhagic Fever/Dengue Shock Syndrome (DHF/DSS) respectively were enrolled for this study. The diagnostic criteria for DI were febrile illness associated with one of the following: 1) detection of dengue-specific IgM capture antibody or Non-Structural Protein1 (NS1) antigen; or 2) a four-fold or greater increase of dengue-specific IgG capture antibody by ELISA and haemoagglutination inhibition assay. Patients were diagnosed as having Acute RF, if serum creatinine was >1.2 mg/dl or who showed improvement by 50% in serum creatinine from the initial value. It is an observational study of medical charts, data of age, gender, and medical history of any underlying diseases in association with the severity of DI of each patient recorded. All of the laboratory results were collected. Parameters that influenced the clinical presentations and outcomes for development of classical DF or DHF/DSS in patients with or without RF were analysed and compared. Descriptive and inferential statistical analysis was carried. The Statistical software namely SAS 9.2, SPSS 15.0, Stata 10.1, Med Calc 9.0.1, Systat 12.0 and R environment ver.2.11.1 were used. Most common symptoms were fever followed by headache and pain in abdomen. Among the patients with RF, all patients had recovery. The patients with DHF/DSS were more susceptible to develop renal failure compared to DF group. There were statistically significant higher frequencies of renal failure, haemoconcentration, thrombocytopenia, low serum cholesterol. Patients in the RF group also had significantly higher percentages of shock, haemoconcentration

    2009-01-01

    Full Text Available Acute renal failure (ARF is a common complication of sepsis and carries a high mortality. Renal replacement therapy (RRT during the acute stage is the mainstay of therapy. Va-rious modalities of RRT are available. Continuous RRT using convective methods are preferred in sepsis-induced ARF, especially in hemodynamically unstable patients, although clear evidence of benefit over intermittent hemodialysis is still not available. Peritoneal dialysis is clearly inferior, and is not recommended. Early initiation of RRT is probably advantageous, although the optimal timing of dialysis is yet unknown. Higher doses of RRT are more likely to be beneficial. Use of bio-compatible membranes and bicarbonate buffer in the dialysate are preferred. Anticoagulation during dialysis must be carefully adjusted and monitored.

    Acute renal failure (ARF) in children with malignancies is a rare clinical situation, but nonetheless it is a serious life threatening condition. It may arise from different clinical situations and may be caused by various factors. The aim of the study was to determine the frequency, aetiology and the course of ARF in children treated for malignancies in the Department of Pediatrics, Hematology, Oncology and Endocrinology, Medical University of Gdansk. A group of 586 pediatric oncology patients treated between 1992 and 2004 were enrolled in a retrospective study. ARF was diagnosed in 29 cases including: 12 patients with prerenal course of ARF (11 due to septic shock and 1 due to dehydration), 16 patients with intrinsic renal aetiology of ARF (as a complication after cisplatinum and carboplatinum therapy in 2 children, in 2 cases after methotrexate, as a consequence of bilateral nephrectomy due to nephroblastoma in 1 patient and in 11 children with tumour lysis syndrome, including 5 patients with neoplasmatic infiltration of kidneys) and postrenal ARF in 1 patient as a first symptom of a tumour located in the small pelvis (Rhabdomyosarcoma). Renal replacement therapy (dialysis) was necessary in 11 children. Among 29 analysed children, in 20 cases renal failure was reversible. Due to appropriate treatment, ARF in course of tumour lysis syndrome is nowadays reversible. ARF due to septic shock or cytostatics nephrotoxicity is a significant therapeutic problem. In most of the cases it is irreversible. 1. ARF in these studies occurred in 29 out of 586 children with malignancies (4.9%). 2. Prerenal and renal ARF were the most frequent forms. 3. Implementation of tumour lysis prophylaxis in the treatment of children with blood system proliferative diseases reduces the incidence of ARF. 4. In cases of ARF in children's malignancies close cooperation between paediatric oncologist and nephrologist is necessary.

    The benefit of reducing the risk of stroke against increasing the risk of renal progression associated with antiplatelet therapy in patients with advanced chronic kidney disease (CKD) is controversial. We enrolled 1301 adult patients with advanced CKD treated with erythropoiesis stimulating agents from January 1, 2002 to June 30, 2009 from the 2005 Longitudinal Health Insurance Database in Taiwan. All of the patients were followed until the development of the primary or secondary endpoints, or the end of the study (December 31, 2011). The primary endpoint was the development of ischemic stroke, and the secondary endpoints included hospitalization for bleeding events, cardiovascular mortality, all-cause mortality, and renal failure. The adjusted cumulative probability of events was calculated using multivariate Cox proportional regression analysis. Adjusted survival curves showed that the usage of aspirin was not associated with ischemic stroke, hospitalization for bleeding events, cardiovascular mortality or all-cause mortality, however, it was significantly associated with renal failure. In subgroup analysis, aspirin use was associated with renal failure in the patients with no history of stroke (HR, 1.41; 95% CI, 1.14-1.73), and there was a borderline interaction between previous stroke and the use of aspirin on renal failure (interaction p=0.0565). There was no significant benefit in preventing ischemic stroke in the patients with advanced CKD who received aspirin therapy. Furthermore, the use of aspirin was associated with the risk of renal failure in the patients with advanced CKD without previous stroke. Copyright © 2016 European Federation of Internal Medicine.

    We evaluated the growth records of 15 boys and 14 girls who developed end-stage renal failure before or during puberty and who were regularly followed from the onset to the end of their pubertal growth spurt. Height data were smoothed by using the kernel estimation method. Mean values for age, height, and height velocity at defined points of the pubertal growth period were compared with those of normal children entering puberty both at an average and late age. The start of the pubertal growth spurt was delayed by 2.5 y in both sexes. Its duration and intensity were significantly reduced. Mean pubertal height gain was 17.3 cm in boys and 13.9 cm in girls, i.e. 58 and 48% of that observed in the late maturing control group. Mean height at the onset of the pubertal spurt in the patients was the same as that in the late maturing healthy girls and 1.0 SD below that of corresponding boys. During the pubertal growth spurt, mean height declined to -2.9 SD in boys and -2.3 SD in girls. Although skeletal maturation was increasingly retarded, we did not observe accelerated growth velocity during late puberty. Our data indicate that most patients reaching end-stage renal failure before or during puberty irreversibly lose growth potential during this period. Renal transplantation did not consistently improve pubertal growth.

  4. Nutritional management of acute renal failure.

    Acute renal failure (ARF) is associated with fundamental alterations of metabolism and immunocompetence with the induction of a pro-oxidative and proinflammatory state. Thus, the objectives of nutritional therapy include not only conventional goals such as maintaining lean body mass and stimulating immunocompetence and repair functions, but also mitigating the inflammatory state and improving the oxygen radical scavenging system and endothelial functions. Moreover, pre-existing and/or hospital-acquired malnutrition has been identified as an important factor contributing to the persistent high mortality in acutely ill patients with ARF. A nutritional program for a patient with ARF must consider not only the specific metabolic consequences associated with renal failure and with the underlying disease process, but also the profound alterations in nutrient balances induced by replacement therapy. Nutrient requirements thus may differ widely between individual patients and during the course of disease, and nutrition therapy must be coordinated with renal replacement therapy. Whenever possible, enteral nutrition should be provided in patients with ARF because even small amounts of luminal nutrients will help to maintain intestinal function. Nevertheless, in many patients parenteral nutrition, at least supplementary and/or temporarily, will become necessary. Because of the complex alterations in the use of various nutrients and the impaired tolerance to electrolytes and volume load, metabolic complications of nutritional support frequently occur in patients with ARF. Therefore, nutrition therapy must be more closely monitored in patients with ARF than with other diseases.

    Atherosclerotic renal artery disease presents with a broad spectrum of clinical features, including heart failure as well as hypertension, and renal failure. Although recent randomized controlled trials failed to demonstrate renal artery stenting can reduce blood pressure or the number of cardiovascular or renal events more so than medical therapy, increasing attention has been paid to flash pulmonary edema and congestive heart failure associated with atherosclerotic renal artery disease. This clinical entity "renovascular heart failure" is diagnosed retrospectively. Given the increasing global burden of heart failure, this review highlights the background and catheter-based therapeutic aspects for renovascular heart failure.

    Renal failure is common in the United States with an estimated prevalence of 660,000 treated end-stage renal disease patients in 2015 [1]. Causes of renal failure are many, and complications from renal failure, underlying disease, and treatment are not infrequent. Examples of common skin manifestations include xerosis, pigmentary change, and nail dystrophies. Frequent disease-specific skin changes may be helpful in the diagnosis of primary disorders leading to renal disease or severity of disease including bullosis diabeticorum, sclerodactyly, or leukoctoclastic vasculitis. Some cutaneous changes, such as the multiple angiokeratomas of Fabry disease or the plexiform neurofibromas of neurofibromatosis, are pathognomonic of genetic disorders, which often lead to renal failure. Careful examination of the skin can provide crucial clues to diagnosis of renal failure causation and aid in monitoring complications. © 2018 S. Karger AG, Basel.

    Full Text Available Rhabdomyolysis is a syndrome caused by skeletal muscle cells destruction which can occur for many reasons, including prolonged immobilization. The main complication of the syndrome is the development of acute renal failure. Rhabdomyolysis and myoglobinuria are responsible for approximately 5% of all causes of acute renal failure in the USA. The cause of rhabdomyolysis is often multifactorial, and approximately 8–20% of such patients develop myoglobinuric acute renal failure.

    We evaluated renal function and the impact of renal function on in-hospital outcomes in patients with ischaemic and haemorrhagic stroke. We collected data from 766 patients with stroke; 637 (83.2 %) with ischaemic and 129 with haemorrhagic one. The mean serum creatinine on admission in patients with both types of stroke, who died, was significantly higher than in those who survived. Multivariate analysis showed that independent predictors of mortality in patients with ischaemic stroke were: ischemic heart disease or prior myocardial infarction, diabetes, admission glucose and eGFR on admission. Also, multivariate analysis showed that independent predictors of mortality in patients with haemorrhagic stroke were: age and admission glucose. Patients with haemorrhagic stroke, in particular with acute kidney injury during hospitalisation had significantly worse outcomes than patients with ischaemic stroke. Assessment of kidney function is prerequisite to employ the necessary measures to decrease the risk of in-hospital mortality among patients with acute stroke. Appropriate approach to patients with renal dysfunction (adequate hydration, avoidance of nephrotoxic drugs, drug dose adjustment etc) should be considered as preventive and therapeutic strategies in the management of acute stroke. © 2016 The Author(s) Published by S.

    Full Text Available INTRODUCTION Acute renal failure (ARF is a frequent clinical condition in neonatal intensive care units (NICU. The leading cause of neonatal ARF is perinatal asphyxia (PS. The aim of this study was to examine the relationship between the degree of PS and the severity of ARF in term neonates. METHODS A prospective survey of 31 term neonates with Ps and but without congenital malformations or sepsis was performed in NICU of the regional Hospital of Gynaecology and Obstetrics in Belgrade (average number of deliveries about 6000 per year. ARF was diagnosed in the first 7 days of life when plasma creatinine was above 133 μmοΙ/L for at least 48 hours while maternal renal function was normal. The degree of PS was determined according to Apgar score (AS at 1 min. The severe PS was defined as AS < 3 and moderate PS as AS 4-6. RESULTS Twenty neonates (64% had oliguric ARF with urine output of 0.37 ±0.16 ml/kg/h while the others had nonoliguric ARF with urine output of 2.4 ± 0.7 ml/kg/h. Most of neonates with oliguric ARF (65% had severe perinatal asphuxia while in those with nonoliguric ARF moderate perinatal asphyxia predominated (73%. DISCUSSION During hypoxic-ischaemic events many organs are injured, and the most vulnerable ones are kidneys and central nervous system. Our results showed a strong connection between perinatal asphyxia and A, which was in accordance with the results of other studies. Neonates with severe perinatal asphyxia had serious impairment of renal function, which was confirmed with strong correlation between Apgar score and plasma creatinine. In neonates with oliguric ARF, but not in those with nonoliguric ARF, the highly positive linear correlations were found between AS and urinary output (r = 0.77; p < 0.01, plasma creatinine (r = 0.78; p < 0.01, fractional excretion of sodium (r = 0.76; p < 0.01, and index of renal failure (r = 0.80; p < 0.01. Only in oliguric neonates with severe perinatal asphyxia (31 % the outcome was

    Full Text Available Acute renal failure (ARF is a serious medical complication during pregnancy, and, in the post-partum period, is associated with significant maternal morbidity and mortality as well as fetal loss. The objective of our study is to find the etiology and maternal outcome of ARF during preg-nancy. The study was conducted at the Obstetrics and Gynecology Department of the Institute of Kidney Disease and Research Center, Ahmedabad, India from January 2009 to January 2011. Fifty previously healthy patients who developed ARF, diagnosed on oliguria and serum creatinine >2 mg%, were included in the study. Patients with a known history of renal disease, diabetes and hypertension were excluded from the study. All patients were followed-up for a period of six months. Patient re-cords, demographic data, urine output on admission and preceding history of antepartum hemorrhage (APH, post-partum hemorrhage (PPH, septicemia, operative interventions and retained product of conception were noted and need for dialysis was considered. Patients were thoroughly examined and baseline biochemical investigations and renal and obstetrical ultrasound were performed on each patient and bacterial culture sensitivity on blood, urine or vaginal swabs were performed in selected patients. The age range was 19-38 years (mean 26 ± 3.8. The first trimester, second trimester and puerperal groups comprised of four (8%, 25 (50% and 21 patients (42%, respectively. Hemorrhage was the etiology for ARF in 15 (30%, APH in ten (20% and PPH in five (10% patients. Eleven (22% patients had lower segment cesarian section (LSCS while 36 (78% patients had normal vaginal delivery. In 20 (40% patients, puerperal sepsis was the etiological factor, while pre-eclampsia, eclampsia and HELLP syndrome accounted for 18 (36% patients. Two (4% patients had dissemi-nated intravascular coagulation on presentation while one (2% patient was diagnosed with hemolytic uremic syndrome. Maternal mortality was 12% (n

    Thromboembolic events, principally stroke, represent one of the leading causes of morbidity and mortality among subjects with atrial fibrillation. Chronic kidney disease determines a further increase of thromboembolic events, bleeding and mortality and complicates the pharmacological management of patients with atrial fibrillation, mainly due to the side effects of antiarrhythmic and anticoagulant drugs with renal excretion. Apixaban is a new oral anticoagulant characterized by good bioavailability and renal elimination accounting for only 25%, showing a safety profile and effectiveness in patients with renal impairment. In this manuscript, we reviewed literature data on the use of apixaban in the management of non-valvular atrial fibrillation in patients with renal failure, in order to clarify an often-debated topic in clinical practice. A PubMed search was performed on the terms atrial fibrillation, apixaban and renal failure with the aim of identifying relevant manuscripts, large randomized clinical trials, meta-analyses, and current guidelines. Literature data show that apixaban could represent an interesting alternative to warfarin and other selective antagonists of coagulation factors in patients with impaired renal function. About the risk of major bleeding, apixaban appears to be safer than warfarin in the presence of any degree of renal failure. Apixaban show to be an effective anticoagulant in patients with atrial fibrillation, even superior to warfarin in reducing the risk of stroke and systemic embolism regardless of the presence of renal insufficiency. Moreover, Food and Drug Administration allows the use of apixaban in patients with end stage renal disease on hemodialysis.

    2015-01-01

    Full Text Available Acute nontraumatic exertional rhabdomyolysis may arise when the energy supply to muscle is insufficient to meet demands, particularly in physically untrained individuals. We report on a psychiatric patient who developed large bruises and hemorrhagic blisters on both hands and arms, rhabdomyolysis of both forearm muscles with a moderate compartment syndrome, and consecutive acute renal failure following excessive work in the garden. Although specifically asked, the patient denied any hard physical work or gardening, and heteroanamnestic data were not available. The diagnosis of rhabdomyolysis was easy to establish, but until reliable anamnestic data were obtained, the etiology remained uncertain. Four days after arrival, the patient recalled working hard in the garden. The etiology of rhabdomyolysis was finally reached, and the importance of anamnestic data was once more confirmed.

    Our aim was to evaluate the clinical profile, treatment, and outcome of ceftriaxone-associated postrenal acute renal failure (PARF) in children. We retrospectively studied 31 consecutive cases from 2003 to 2012 for PARF after ceftriaxone treatment. There was no past history of urolithiasis or nephropathy in these children. The average time of ceftriaxone administration before PARF was 5.2 days. The major symptoms apart from anuria included flank pain (>3 years old, 25/25), excessive crying (Ceftriaxone was verified to be the main component of the calculi in 4 children by tandem mass spectrometric analysis. The recovery was complete in all cases. Ceftriaxone therapy in children may cause PARF. Early diagnosis and prompt pharmacological therapy are important in relieving the condition. Retrograde ureteral catheterization is an effective treatment of those who fail to respond to pharmacotherapy.

    Aggrenox is used in the secondary prevention of stroke. Acute renal failure, potentially associated with Aggrenox, has been observed in several patients. The objective of this study was to determine if Aggrenox was associated with acute renal failure and to determine whether it was acetylsalicylic acid, dipyridamole or the combination that led to decline in renal function. A case series of three patients suffering severe nausea, vomiting, diarrhea, renal dysfunction and clinical decline during Aggrenox therapy was examined. Serum creatinine and Blood Urea Nitrogen (BUN) were measured to evaluate renal function. Analysis of this patient group revealed that Patient 1 experienced nausea, emesis, anorexia, diarrhea and significant clinical decline during treatment with Aggrenox. Patients 2 and 3 also presented with complaints of nausea and emesis. Lab measurements along with clinical symptoms indicated that all three patients experienced acute renal failure, having increases in serum creatinine of 186%, 144% and 249%, respectively. Symptoms and lab work returned to baseline following discontinuation of Aggrenox. It is biologically plausible that Aggrenox may contribute to renal dysfunction in patients under certain pathophysiological circumstances.

    Full Text Available Background/Aim. Hemodynamic stress is the leading cause of acute renal failure (ARF in premature neonates. Incidence of ARF in this population is between 8 and 24%. The aim of this study was to determine the frequency of presence of ARF in premature neonates, as well as its impact on their survival. Methods. A retrospective study of 114 premature neonates [(gestational age, GA less than 37 gestation weeks (gw] admitted to the Intensive Care Unit (ICU at the Pediatric Clinic, Institute of Child and Youth Healthcare of Vojvodina in 2007 was conducted. Serum creatinine, urea and bilirubine were determined on the 3rd day of life in 65 newborns who met inclusion criteria. ARF was diagnosed in 16 newborns (n=16/65; 25%. Results. The premature neonates with ARF had significantly lower GA [<28 gw - 8/16 (50% vs. 5/49 (10%; p < 0.05], birth weight (BW (1 265 g vs. 1615 g; p < 0.05 and systolic blood pressure (43.37 mm Hg vs. 52.7 mmHg; p < 0.05 than ones without ARF. Non-olyguric ARF was diagnosed in 62% of newborns with ARF (n=10/16, while the rest had the olyguric type (n = 6/16; 38%. Twenty-five percent of premature neonates with ARF (n = 4/16 died in contrast to 10% of premature neonates without ARF (n = 5/49. ARF was treated conservatively in all but 3 cases when peritoneal dialysis was performed. Renal function has recovered completely in all of the survivors. In order to determine their predictivity in relation to ARF, following parameters were analyzed: GA, BW < 1 500 g, presence of concomitant sepsis and intracranial hemorrhage grade III/IV. BW < 1 500 g demonstrated the highest sensitivity (se 0.75, while GA < 28 gw, sepsis and intracranial hemorrhage grade III/IV showed high specificity (sp = 0.90, 0.89 0.88, respectively. Conclusion. Acute renal failure frequently occurs in population of premature neonates and requires meticulous fluid and electrolyte balance, especially in the case of low birth weight and extreme immaturity.

    Malaria has protean clinical manifestations and renal complications, particularly acute renal failure that could be life threatening. To evaluate the incidence, clinical profile, ou 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 coagulation, and high serum creatinine were the main predictors of mortality. We conclude that malaria is associated with acute renal failure, which occurs most commonly in plasmodium falciparum infected patients. Early diagnosis and prompt dialysis with supportive management can reduce morality and enhance recovery of renal function (Author).

    Clinical observations were made in five Buddhist monks with chronic renal failure on a low protein diet. These monks consumed only one meal and meditated three to four times a day. The estimated protein intake was from 15 to 19 g a day. Renal function remained stable over three years of observation. The general condition was satisfactory without any evidence of protein energy malnutrition. The data were compared with those of another group of patients who had a comparable degree of impairment of renal function but who consumed three meals a day of low protein diet. Protein intake was estimated to be from 25 to 30 g a day. These patients developed uraemia with severe renal failure and protein deficiency within three years. The findings support the role of protein restriction in maintenance of renal function in chronic renal failure and perhaps suggest a beneficial role for meditation.

    The sarcoidosis is a systemic granulomatosis affecting most frequently the lungs and the mediastinum. An acute renal failure reveals exceptionally this disease. It's a retrospective study implicating 12 cases of sarcoidosis complicated of acute renal failure. The aim of this study is to determine epidemiological, clinical, biological and histological profile in these cases and then to indicate the interest to consider the diagnosis of sarcoidosis in cases of unexplained renal failure. Extra-renal complications, therapeutic modalities and the outcome were determined in all patients. Our series involved 12 women with an average age of 40 years. Biological investigations showed an abnormal normocalcemia in 7 cases, a hypercalcemia in 5 cases, a hypercalciuria in 10 cases and polyclonal hypergammaglobulinemia in 7 cases. An acute renal failure was found in all patients with a median creatinin of 520 umol/L. For all patients, the renal echography was normal however, the kidney biopsy showed tubulo-interstitial nephritis. The extra-renal signs highlighting pulmonary interstitial syndrome in 5 cases, a sicca syndrome in 4 cases, mediastinal lymph nodes in 2 cases, a lymphocytic alveolitis in 3 cases, an anterior granulomatous uveitis in 2 cases and a polyarthritis in 5 cases. Five patients benefited of hemodialysis. The treatment consisted of corticosteroid in all cases. The follow up was marked by complete resolution of clinical and biological signs. The diagnosis of renal sarcoidosis must be done quickly to prevent renal failure.

    Full Text Available Tuberculosis is a multiorgan disease with varied clinical presentations and is reemerging due to increasing immigration and globalization. We present the case of an immigrant female patient who developed acute renal failure with clinical and biochemical features suggestive of lupus nephritis but with a timely renal biopsy showing caseating granulomata in the renal parenchyma consistent with renal tuberculosis. Despite treatment with antituberculosis treatment and resolution of TB on repeat renal biopsy, she remained haemodialysis dependent. We discuss the diagnostic challenges faced in this presentation and also explore possible differential diagnoses. This rare presentation highlights the importance of renal biopsy in the diagnosis and treatment of acute renal failure and the atypical presentation of tuberculosis.

    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. 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. 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 renal failure, to prevent the risk of bleeding, platelet count should be checked periodically.

    This case report outlines a significant type of morbidity due to continued use of gabapentin during an episode of acute renal failure. Setting. University teaching hospital. Gabapentin is widely used in the management of pain. It is entirely excreted through the renal system so this needs to be considered in any patient becoming acutely ill and developing renal failure. We describe a patient who developed significant deterioration in her conscious level due to iatrogenic gabapentin overdose. All doctors need to be aware of the need to review the indications for gabapentin use during periods of acute illness, especially with regard to renal impairment. Off-label use should be discouraged.

    Acute renal failure (ARF) occurs in up to 10% of critically ill patients, with significant associated morbidity and mortality. The optimal mode of renal replacement therapy (RRT) remains controversial. This retrospective study compared continuous renal replacement therapy (CRRT) and intermittent hemodialysis (IHD) for RRT in terms of intensive care unit (ICU) and hospital mortality, and renal recovery. We reviewed the records of all patients undergoing RRT for the treatment of ARF over a 12-month period. Patients were compared according to mode of RRT, demographics, physiologic characteristics, and outcomes of ICU and hospital mortality and renal recovery using the Chi square, Student's t test, and multiple logistic regression as appropriate. 116 patients with renal insufficiency underwent RRT during the study period. Of these, 93 had ARF. The severity of illness of CRRT patients was similar to that of IHD patients using APACHE II (25.1 vs 23.5, P = 0.37), but they required significantly more intensive nursing (therapeutic intervention scale 47.8 vs 37.6, P = 0.0001). Mortality was associated with lower pH at presentation (P = 0.003) and increasing age (P = 0.03). Renal recovery was significantly more frequent among patients initially treated with CRRT (21/24 vs 5/14, P = 0.0003). Further investigation to define optimal timing, dose, and duration of RRT may be beneficial. Although further study is needed, this study suggests that renal recovery may be better after CRRT than IHD for ARF. Mortality was not affected significantly by RRT mode.

  15. Renal tolerance for iopromide (ultravist) in patients with chronic renal failure. Preliminary report

    The authors present the renal tolerance for nonionic low-osmotic contrast agent iopromide (ultravist) on the ground of literature and of angiographic examinations in 10 patients with chronic renal failure. One patient only had significant temporary deterioration of renal function. The presented results showed that analyzed agent is less nephrotoxic than high osmolality contrast agents. The use of iopromide is strongly recommended in patients with chronic renal failure. The risk of depression of renal function after administration of contrast material is minimized. (author)

    Twenty-four survivors of acute, nonobstructive, nonnephritic renal failure had a renal scan using iodohippurate sodium I 131 performed early in the acute illness. Scans were judged according to whether the renal images were prominent, faint, or absent during the first 30 minutes after intravenous injection of 100 to 250 microcuries of iodohippurate sodium I 131. All ten patients with prominent renal images attained life-sustaining renal function with an average postrecovery creatinine clearance of 80 ml/min. Of the seven patients with faint renal images, six recovered life-sustaining renal function (average creatinine clearance of 39 ml/min), and one required chronic hemodialysis. Seven patients had no renal image initially; four recovered life-sustaining renal function with an average creatinine clearance of 25 ml/min; three required chronic hemodialysis. We conclude that, for patients with acute renal failure, the appearance of the renal image obtained using this substance is an important indicator of renal viability and of the likelihood for functional recovery

    Objective: To identify the causes of acute renal failure (ARF) in pediatric population along with the identification of the age and gender most affected by the failure. Subjects and Methods: The study included children under the age of 12 years who presented with signs and symptoms suggestive of ARF (oliguria/anuria, vomiting, acidotic breathing etc.) along with raised blood urea nitrogen (BUN) serum creatinine and metabolic acidosis as shown by arterial blood gases (ABGs). Patients were divided into two group on the basis of age; group A consisting of 0-2 years and group B from >2 years. Patients presenting with transient pre-renal azotaemia were excluded from the study. After providing initial emergency cover, detailed history, physical examination and investigations were carried out according to a proforma specially designed to ascertain the cause of ARF. Patients were managed for ARF as per standard recommendations and investigations completed or repeated as and when required. Results: A total of 119 patients with ARF were admitted in the ward over a period of two years constituting 1.36% of the total admissions and 16.39% of the admissions due to renal pathology. Mean age of presentation was 4.5 years 16.7% of the patients under the age of 5 years. Male predominance was noted in all ages with an overall male to female ratio of 2.3:1. Most common cause leading to ARF in younger age group was found to be hemolytic uremic syndrome [25(54.34%)] followed by septicemia [7(15.21 %)]. In older patients renal calculus disease was the most common [22(30.13%)] underlying pathology followed by pre-existing, undiagnosed chronic renal failure [16(21.91 %)]. Conclusion: ARF is fairly cotton in children especially under the age of 5 years showing a male predominance. More than 90% of the cases can be prevented by improving primary health care and by early and prompt treatment of infections. (author)

  19. CT of the kidney in chronic renal failure

    Kojima, Kanji

    1988-01-01

    The transverse size of the kidneys was measured by CT, and CT findings of the kidneys were studied in 94 patients with chronic renal failure under hemodialysis (HD), 58 patients with chronic renal failure not under hemodialysis (CRF) and 100 controls. The transverse size of the kidneys decreased according to the deterioration of renal function. The ratio of the maximal renal transverse size to the minimal vertebral size, which the author proposed as a new criterion for renal atrophy, was 1.8 in controls, 1.2 in CRF and 0.8 in HD. A kidney smaller than the vertebral body indicated chronic renal failure. Characteristic CT features in CRF were mild renal atrophy and cystic changes (41.4 %). In HD, renal atrophy was more advanced, the occurrence of cystic changes was more frequent (64.9 %), and there were frequent renal (68.1 %) and aortic calcifications. Furthermore acquired cystic disease of the kidney (ACD) was observed (27.7 %) only in HD. In this study no renal neoplasm was found in ACD. However, several complications in HD, one perirenal hematoma and six hydronephroses, were observed. (author)

    Full Text Available BACKGROUND: We have noticed a recent rise in the incidence and severity of acute renal failure (ARF in malaria. AIM: To study the incidence, severity and outcome of ARF in malaria. SETTING and DESIGN: It is a retrospective analysis of data of one year from a tertiary medical centre in a metropolitan city. MATERIALS AND METHODS: Patients with ARF and smear positive malaria were evaluated. STATISTICAL ANALYSIS: Results were expressed as mean, range and standard deviation. RESULTS: Out of 402 detected smear positive malaria, 24 had ARF. Eighteen were of the age group 21-40 years. Plasmodium falciparum (PF was detected in 16, Plasmodium vivax in three, and mixed infection in five. Non-oliguric ARF was seen in 14. Eighteen showed severe ARF (Serum creatinine >5 mg%. Twenty-two patients needed dialysis. Prolonged ARF lasting for 2-6 weeks was seen in eight. Seventeen patients recovered completely, while seven showed fatal combination of disseminated intravascular coagulation (DIC, acute respiratory distress syndrome (ARDS, severe ARF and PF malaria. No response was seen to chloroquine and artesunate given alone and twenty patients required quinine. CONCLUSION: ARF necessitating dialysis was seen in 92% of patients with ARF in malaria. PF infection, severe ARF, DIC and ARDS were poor prognostic factors. Resistance was noted to both chloroquine and artesunate.

    Whether or not the definition of a worsening renal function (WRF) is adequate for the evaluation of acute renal failure in patients with acute heart failure is unclear. One thousand and eighty-three patients with acute heart failure were analysed. A WRF, indicated by a change in serum creatinine ≥0.3 mg/mL during the first 5 days, occurred in 360 patients while no-WRF, indicated by a change failure; n = 98). The patients were assigned to another set of four groups: no-WRF/no-AKI (n = 512), no-WRF/AKI (n = 211), WRF/no-AKI (n = 239), and WRF/AKI (n = 121). A multivariate logistic regression model found that no-WRF/AKI and WRF/AKI were independently associated with 365 day mortality (hazard ratio: 1.916; 95% confidence interval: 1.234-2.974 and hazard ratio: 3.622; 95% confidence interval: 2.332-5.624). Kaplan-Meier survival curves showed that the rate of any-cause death during 1 year was significantly poorer in the no-WRF/AKI and WRF/AKI groups than in the WRF/no-AKI and no-WRF/no-AKI groups and in Class I and Class F than in Class R and the no-AKI group. The presence of AKI on admission, especially Class I and Class F status, is associated with a poor prognosis despite the lack of a WRF within the first 5 days. The prognostic ability of AKI on admission may be superior to WRF within the first 5 days. © 2018 The Authors.

    2005-05-01

    Full Text Available A 62-year-old male was sent to the emergency room due to a high fever and generalized skin rash after taking allopurinol for 9 days. Physical examination was normal except for the generalized skin rash presenting with erythematous macules. Complete blood count showed leukocytosis with eosinophilia. Blood biochemistry showed impaired renal and hepatic function. Pathologic examination concluded that the skin rash was erythema multiforme. These findings met the diagnostic criteria for allopurinol-induced hypersensitivity syndrome (AHS. Our patient not only had the most common skin lesion but soon developed acute renal failure that required intermittent hemodialysis, despite rapid discontinuation of allopurinol and adequate hydration and steroid therapy. No other causes of acute renal failure were found. Renal impairment was the worst part of the patient's condition and he never completely recovered. AHS should be considered in the differential diagnosis of acute renal and hepatic failure in patients with evidence of allergy and recent use of allopurinol.

    Full Text Available Multiple Myeloma (MM frequently presents with renal dysfunction apart from other manifestations. Development of renal failure in patients with MM carries a poor prognosis. Bortezo-mib is a new addition to drugs used in MM and has shown good efficacy and safety profiles. Previous trials have shown its efficacy in relapsed and refractory MM as well. Studies have also shown that bortezomib is also effective in patients with MM who present with renal failure. We report here six cases of renal failure secondary to MM treated with bortezomib. All patients had poor performance status of 3-4 on ECOG scale. Five out of six patients showed satisfactory anti-myeloma response to bortezomib. Reversal of renal failure was observed in all six patients. Adverse effects to bortezomib were mild and manageable. Reversal of renal failure persisted despite incomplete response to MM in two cases, and progression of disease in one patient. It appears that bortezomib may have an effect on the kidneys in reversal of renal failure, other than its anti-myeloma effect. In conclusion, borte-zomib appears to be an effective treatment for patients with advanced MM and renal failure irres-pective of performance status and age.

    Previous data are controversial about the association of renal artery stenosis (RAS) with clinical outcome in patients with heart failure. Definition of RAS in previous studies might not be appropriate. By definition of RAS with renal duplex sonography, we investigated the association of RAS with clinical outcome in patients with heart failure. In this retrospective study, we identified 164 patients with heart failure (New York Heart Association classification ≥II; left ventricular ejection fraction renal duplex sonography during hospital stay. RAS was defined as renal-aortic ratio ≥3.5 or a peak systolic velocity ≥200 cm/s (or both), or occlusion of the renal artery. Categorical data of patients were compared using the Chi-square test or Fisher's exact test. Cox proportional hazards regression modeling technique was used to investigate the prognostic significance of possible predictors. Finally, 143 patients were enrolled. Median follow-up time was 32 months (1-53 months). Twenty-two patients were diagnosed as RAS by renal duplex sonography, including 13 unilateral RAS (3 left RAS, 10 right RAS) and 9 bilateral RAS. There were more all-cause mortality and cardiovascular death in patients with RAS than patients without RAS. By multivariate analysis, RAS was a significant predictor for all-cause death and cardiovascular death (hazard ratio [HR] = 4.155, 95% confidence interval [CI]: 1.546-11.164, P = 0.005; and HR = 3.483, 95% CI: 1.200-10.104, P = 0.022, respectively). As for composite endpoint events, including death, nonfatal myocardial infarction, ischemic stroke or intracranial hemorrhage, rehospitalization for cardiac failure, and renal replacement therapy, only angiotensin-converting enzyme inhibitor or angiotensin-receptor blocker was significant predictor. RAS was not a significant predictor for composite endpoint events. Our data suggested that RAS is associated with a poorer clinical outcome in patients with heart failure.

    Synthetic cannabinoid usage has increased in the past decade. Concurrently, emergency management of associated adverse effects due to synthetic cannabinoid usage has also risen. Reported toxicities include psychosis, seizures, cardiotoxicity, acute kidney injury, and death. While cannabis was first described as a cause of acute hyperemesis in 2004, a more recent case series also describes the association between cannabinoid hyperemesis and risk of acute renal failure. Synthetic cannabinoids have also been reported to cause acute hyperemesis and acute renal failure; however, the risk of rhabdomyolysis-induced renal failure has yet to be elucidated. In this article, we report the first known case of synthetic cannabinoid hyperemesis leading to rhabdomyolysis and acute renal failure.

    Oxaliplatin is an effective chemotherapeutic agent frequently used in the treatment of colorectal carcinoma. Rare cases of renal failure and hemolytic reactions have been reported as separate side effects of oxaliplatin. Here we present a clinical picture of immune-related intravascular hemolysis and acute tubular necrosis in a patient receiving this drug. This case suggests a mechanistic explanation of renal failure in patients treated with oxaliplatin.

    A young male presented in the Nephro-Urology Department with advanced renal failure, blindness in early childhood, polydactaly,obesity, decreased mentation and hypogonadism. With these phenotypical features and renal ultrasonographic findings, he was diagnosed as a case of Bardet-Biedl syndrome. Only one younger sister of patient had similar features. Renal impairment is frequent and an important cause of death. End stage renal disease (ESRD) is rarely seen in younger patient of Bardet-Biedl syndrome. However, ESRD in early age is associated with substantially reduced survival. (author)

    2002-01-01

    In conscious, chronically instrumented rats we examined 1) renal tubular functional changes involved in lipopolysaccharide (LPS)-induced acute renal failure; 2) the effects of LPS on the expression of selected renal tubular water and sodium transporters; and 3) effects of milrinone......-alpha and lactate, inhibited the LPS-induced tachycardia, and exacerbated the acute LPS-induced fall in GFR. Furthermore, Ro-20-1724-treated rats were unable to maintain MAP. We conclude 1) PDE3 or PDE4 inhibition exacerbates LPS-induced renal failure in conscious rats; and 2) LPS treated rats develop an escape......, a phosphodiesterase type 3 (PDE3) inhibitor, and Ro-20-1724, a PDE4 inhibitor, on LPS-induced changes in renal function.

    Cerebrovascular disease may represent an important clinical presentation of atherosclerosis in chronic kidney disease (CKD), and atherosclerosis is frequently encountered in CKD. In fact, kidney disease is now considered a risk factor for development of cardiovascular disease. Although guidelines for primary prevention of stroke have been recently published, CKD is hardly mentioned. Based on a series of available studies, we analyzed the relationship between reduced renal function, end-stage renal disease (ESRD), and stroke. Reduced renal function and risk of stroke appear to be related to the highest risk of patients on dialysis treatment. Primary and secondary prevention of stroke should be encouraged in participants with renal dysfunction.

    Prior studies have demonstrated adverse risk associated with baseline and worsening renal function in acute heart failure, but none has modeled the trajectories of change in renal function and their impact on outcomes. We used linear mixed models of serial measurements of blood urea nitrogen and creatinine to describe trajectories of renal function in 1962 patients with acute heart failure and renal dysfunction enrolled in the Placebo-Controlled Randomized Study of the Selective A1 Adenosine Receptor Antagonist Rolofylline for Patients Hospitalized with Acute Decompensated Heart Failure and Volume Overload to Assess Treatment Effect on Congestion and Renal Function study. We assessed risk of 180-day mortality and 60-day cardiovascular or renal readmission and used Cox regression to determine association between renal trajectories and outcomes. Compared with patients alive at 180 days, patients who died were older, had lower blood pressure and ejection fraction, and higher creatinine levels at baseline. On average for the entire cohort, creatinine rose from days 1 to 3 and increased further after discharge, with the trajectory dependent on the day of discharge. Blood urea nitrogen, creatinine, and the rate of change in creatinine from baseline were the strongest independent predictors of 180-day mortality and 60-day readmission, whereas the rate of change of blood urea nitrogen from baseline was not predictive of outcomes. Baseline blood urea nitrogen>35 mg/dL and increase in creatinine>0.1 mg/dL per day increased the risk of mortality, whereas stable or decreasing creatinine was associated with reduced risk. Patients with acute heart failure and renal dysfunction demonstrate variable rise and fall in renal indices during and immediately after hospitalization. Risk of morbidity and mortality can be predicted based on baseline renal function and creatinine trajectory during the first 7 days. URL: http://www.clinicaltrials.gov.

    In Western countries with typically elderly ischaemic acute heart failure patients, predictors and clinical outcome of renal dysfunction and worsening renal function are well described. However, the prevalence, predictors and clinical outcome of renal dysfunction in younger, mainly hypertensive acute heart failure patients from Africa, have not been described. From 1006 patients enrolled in the sub-Saharan Africa Survey of Heart Failure (THESUS-HF), renal function was determined by the estimated glomerular filtration rate using the Modification of Diet in Renal Disease (MDRD) formula. Worsening renal function was defined as an increase in creatinine ≤0.3 mg/dL (26.5 µmol/L) from baseline to day 7/discharge. The mean (SD) age of the patients was 52.4 (18.2) years, 481 (50.8%) were women and the predominant race was black African [932 of 946 (98.5%)]. Heart failure was most commonly a result of hypertension (n = 363, 39.5%) and only 7.8% had ischaemic heart failure. At hospital admission, 289 patients (30.6%) had an estimated glomerular filtration rate ≤60 ml/min.1.73 m2 . Worsening renal function during hospitalization was detected in 53 (9.8 %) of 543 patients with a follow-up creatinine value, and was independently associated with the Western sub-Saharan region, body mass index, and the presence of rales. Worsening renal function was an independent predictor of death or readmission over 60 days [multivariable hazard ratio = 2.06 (1.10, 3.38); P = 0.023] and all-cause death over 180 days [multivariable hazard ratio =1.92 (1.08, 3.38); P = 0.025]. Renal dysfunction is also prevalent in younger non-ischaemic acute heart failure patients in Africa, but worsening renal function is less prevalent and has different predictors compared with Western cohorts. Nevertheless, worsening renal function is strongly and independently related with clinical outcome. © 2014 The Authors. European Journal of Heart Failure © 2014 European Society of Cardiology.

    `Hematologic malignancies (leukemia, lymphoma, multiple myeloma, et al.), as well as solid tumours (renal, liver, lung, ovarian, etc.), can lead to acute or chronic renal failure.The most common clinical manifestation is acute renal failure within the tumour lysis syndrome (TLS). It is characterized by specific laboratory and clinical criteria in order to prove that kidney disorders result from cytolysis of tumour cells after chemotherapy regimen given, although on significantly fewer occasions it is likely to occur spontaneously or after radiotherapy. Essentially, failure is the disorder of functionally conserved kidney or of kidney with varying degrees of renal insufficiency, which render the kidney impaired and unable to effectively eliminate the end products of massive cytolysis and to correct the resulting disorders: hyperuricemia, hyperkalemia, hypocalcaemia, hyperphosphatemia, and others. The risk of TLS depends on tumour size, proliferative potential of malignant cells, renal function and the presence of accompanying diseases and disorders. Hydration providing adequate diuresis and administration of urinary suppressants (allopurinol, febuxostat) significantly reduce the risk of developing TLS. If prevention of renal impairment isn't possible, the treatment should be supplemented with hemodynamic monitoring and pharmacological support, with the possible application of recombinant urate-oxidase enzyme (rasburicase). Depending on the severity of azotemia and hydroelectrolytic disorders, application of some of the methods of renal replacement therapy may be considered.

    Objective: To investigate the significance of renal arterial embolization nephrectomy for treating post-transplanted renal failure. Methods: 15 cases of post-transplanted renal failure received renal arterial embolization. The post-procedural efficacies were followed up for about 6 months to 4 years. Results: Among the 15 cases, 11 showed blood pressure decreasing to normal level, 3 with reduction of the drug dose for anti-hypertension and 1 of no response. In addition, 12 suffered from postprocedural anuria, and 3 with obvious hypourocrinia associated with significant decrease of proteinuia; 5 with positive lymphcytic population response antigen (PRA > 20%), but turning negative with 3 of them after 3 weeks. All the transplanted kidneys revealed different degrees of atrophy but 4 of them obtained chances of successful retransplantation 3- 6 months after the procedure, 3 of them with follow up of 1-3 years were being well. Conclusions: Renal arterial embolization is a safe, efficient measure for treating post-transplanted renal failure with obvious decrease of correlative clinical symptoms and providing conditions for renal retransplantation.

    Acute renal failure (ARF) is a syndrome characterised by rapid decline in glomerular filtration rate and retention of nitrogenous waste products such as urea and creatinine. The objective of this study was to study the prevalence, risk and outcome of women with obstetrical renal failure. Methods: This observational study was conducted in Department of Obstetrics and Gynaecology, Liaquat University Hospital, Hyderabad, Pakistan from October 2009 to September 2010. Thirty-five patients with obstetrical acute renal failure were included in the study, patients with chronic renal diseases, hypertension, diabetes mellitus and renal stones were excluded from the study. A detailed history was followed by thorough examination and investigation. Their clinical history, physical examination and intake/urine output was recorded. Routine laboratory investigations were done related to each case and specialised investigations like renal scan, renal ultrasonography and renal biopsies were performed in selected cases where recovery was delayed for more than 3 weeks. Results: Total numbers of admissions in obstetric ward were 3,285. Pregnancy related acute renal failure was found in 35 (1.065%) women. Age ranged from 18-40 years. Most of the women belonged to age group 30-35. Out of 35 women 31.42% had postpartum haemorrhage. Ante partum haemorrhage was found in 25.71%, Eclampsia in 17.14%, DIC in 14.28%, and sepsis in 11.42%. Anuria was observed in 25 patients, remaining presented with oliguria (28.57%). Haemodialysis was done in 75% of patients, others were managed conservatively. Complete recovery was observed in 53% cases. Maternal mortality was 25.71% and foetal mortality was 22.85%. Conclusion: Pregnancy related ARF is one of the most common causes of ARF, it is a dangerous complication of pregnancy which carries very high mortality and morbidity. (author)

    Full Text Available Exertional rhabdomyolysis is sequela that is occasionally seen after strenuous exercise. The progression to compartment syndrome or renal failure is a rare complication that requires prompt recognition and treatment to prevent morbidity (Giannoglou et al. 2007. We present a case of a 22-year-old college football player who presented to the emergency department (ED after a typical leg workout as part of his weight conditioning. He was found to have rhabdomyolysis with evidence of renal insufficiency. His condition progressed to bilateral compartment syndrome and renal failure requiring dialysis. After bilateral fasciotomies were performed he had resolution of his compartment syndrome. He continued to be dialysis dependent and had no return of his renal function at discharge 12 days after admission.

    Full Text Available Heart failure (HF is a serious debilitating condition with poor survival rates and an increasing level of prevalence. Heart failure is associated with an increase in renal norepinephrine spillover, which is an independent predictor of mortality in HF patients. The excessive sympatho-excitation that is a hallmark of heart failure has long-term effects that contribute to disease progression. An increase in directly recorded renal sympathetic nerve activity has also been recorded in animal models of heart failure. This review will focus on the mechanisms controlling sympathetic nerve activity to the kidney during normal conditions and alterations in these mechanisms during heart failure. In particular the roles of afferent reflexes and central mechanisms will be discussed.

    The acute renal failure is the frequent medical complication observed in liver transplant patients. The objective of this study was to determine the cause of acute renal failure in post liver transplant patients. A total of 70 patients who underwent (cadaveric 52, live 18) liver transplantation were categorized based on clinical presentation into two groups, namely hepatorenal failure (HRF, n = 29), and Hepatic failure (HF, n = 41). All the patients after the liver transplant had received tacrolimus, mycophenolate and steroids. We analyzed the modification of diet in renal disease, (MDRD) serum urea, creatinine and albumin before and after 5th and 30th day of liver transplant and data was categorized into survivors and non-survivors group. In HRF survivor group, serum creatinine, and urea levels were high and, albumin, MDRD were low in pre- transplant and reached to normal levels on 30th day of post transplant, and 79.3 % of patients in this group showed resumption of normal kidney function. On the contrary in HRF nonsurvivor group, we did not observed any significant difference and 20.7 % of patients showed irreversible changes after the liver transplant. In HF survivor group, 82.9 % of liver failure patients did not show any deviation in serum creatinine, urea, albumin and MDRD, whereas in HF non survivor group, 17.1 % of liver failure patients who had HCV positive before the transplant developed acute renal failure. The levels of creatinine, urea, albumin and MDRD were normal before the transplant and on day 30th, the levels of albumin and MDRD were significantly low whereas serum urea, creatinine levels were high. In conclusion, based on these observations, an diagnosis and treatment of Acute renal failure is important among the liver transplantation cases in the early postoperative period.

    Nutritional support constitutes a fundamental approach to favour the management of chronic renal failure and to postpone the need of kidney dialysis. The specific goals of the nutrition intervention are: control of protein intake, control of phosphate and of calcium intake, control of potassium intake, control of energy intake, control of lipid intake with clear identification of the polyunsaturated vs monounsaturated vs saturated fatty acid rate, control of vitamin intake, prevention of malnutrition and intervention with oral supplements or artificial nutrition (even if for short time) if malnutrition occurs. The proper management of the nutritional problems of patients with chronic renal failure slows the disease progression, prevents or controls symptoms associated with uremia and postpones the beginning of substitutive treatment that is of hemodialysis or of peritoneal dialysis, thus allowing a better quality of life either in the short or long term for patients suffering of chronic renal failure.

    In the United States, nearly 1000 annual cases of heat stroke are reported but the frequency and outcome of severe liver injury in such patients is not well described. The aim of this study was to describe cases of acute liver injury (ALI) or failure (ALF) caused by heat stroke in a large ALF registry. Amongst 2675 consecutive subjects enrolled in a prospective observational cohort of patients with ALI or ALF between January 1998 and April 2015, there were eight subjects with heat stroke. Five patients had ALF and three had ALI. Seven patients developed acute kidney injury, all eight had lactic acidosis and rhabdomyolysis. Six patients underwent cooling treatments, three received N-acetyl cysteine (NAC), three required mechanical ventilation, three required renal replacement therapy, two received vasopressors, one underwent liver transplantation, and two patients died-both within 48 hours of presentation. All cases occurred between May and August, mainly in healthy young men because of excessive exertion. Management of ALI and ALF secondary to heat stroke should focus on cooling protocols and supportive care, with consideration of liver transplantation in refractory patients. © 2017 John Wiley & Sons A/S.

    To determine the factors predicting renal outcome in patients developing acute renal failure in pregnancy. Study Design: Descriptive cohort study. Place and Duration of Study: Study was conducted at Nephrology Unit of Sindh Institute of Urology and Transplantation, Karachi, from October 2006 to March 2007. Methodology: Patients with acute renal failure due to complications of pregnancy, with normal size of both the kidneys on ultrasound were enrolled, and followed for a period of 60 days or until recovery of renal function. Patient's age and parity, presence of antenatal care, type of complication of pregnancy, foetal outcome and duration of oliguria were compared between patients who remained dialysis dependent and those who recovered renal function. Chi-square/Fisher's exact test and student's t-test, were used for determining the association of categorical and continuous variables with dialysis dependency. Results: The mean age was 29 +- 6 years. Most patients came from rural areas of interior Sindh. Sixty eight percent did not have antenatal checkups. Antepartum haemorrhage (p=0.002) and prolonged duration of oliguria (35 +- 15.7 days, p= < 0.001) were associated with dialysis dependency, which was observed in 50% of the study group. Conclusion: Ante-partum haemorrhage and prolonged oliguria were strong predictors of irreversible renal failure. This highlights the need for early recognition and referral, and the importance of trained birth attendants and antenatal care. (author)

  17. Contrast media induced acute renal failure in diabetics

    Dehydration, preexisting renal insufficiency, multiple myeloma and insulin-dependent diabetes mellitus are known risk factors for a radiocontrast medium induced acute renal failure. In 90% of patients with insulin-dependent diabetes mellitus, renal insufficiency and proteinuria, a further detoriation of renal function can be expected after i.v. administration of radiocontrast medium. Recent concepts on the genesis of acute renal failure after radiocontrast medium in multiple myeloma emphasize the role of tubular blocade (tubular precipitation of myeloma protein with contrast medium). In insulin-dependent diabetic patients we found altered carbohydrate composition of urinary Tamm Horsfall Protein (THP), with increased glucose and diminished N-acetyl-neuraminicacid content. This was paralleled by a difference in an in-vitro system of coprecipitation where THP of diabetes triggered more pronounced calcium dependent coprecipitation of contrast medium and albumin. These in-vitro findings might be important for the explanation of the genesis of radiocontrast medium-induced acute renal failure in insulin-dependent diabetes mellitus. (orig.) [de

    Full Text Available Diabetic nephropathy is a progredient disease which leads to the end stage renal disease and stands for a leading cause of its development in western countries. About one third of patients included in the dialysis program or transplanation program in the USA are diabetics. The aim of the paper was to analyze the degree of renal failure in diabetics by measuring the glomerular filtration rate (GFR and to show the advantages of this method comparing with serum creatinine levels. Total numbers of 23 patients with diabetes mellitus type 1 or type 2 were anlyzed and controlled monthly during 6 months. Average GFR in the examined patients was 53,23±15,48 mL/min/1.73m2. Obtained values for GFR according to CKD Care and ESRD recommendations showed that the great number of diabetics had stage 3 renal failure while stages 1 and 5 were not registered. GFR is an important marker for diagnostics and estimation of renal failure progression in diabetics. Bearing in mind this facts, periodical controls in diabetics must be suplemented by measuring GFR, so as to perform early identification and determination of severity of renal failure. Measuring of lipoprotein levels and determination of glycemic profile must be done according to the National recommendations twice a year. Besides adequate glycoregulation, diabetics need statins therapy and antyhipertensive tratment with ACE inhibitors.

    Posterior urethral valves (PUVs) are the most common etiology for congenital urethral obstruction and congenital bilateral renal obstruction. PUVs produce a spectrum of urologic and renal sequelae. Our aims were to assess outcomes of PUV patients, to determine whether vesicoureteral reflux (VUR) is a risk factor for progression to renal failure, and to identify other risk factors for poor outcomes. We conducted a retrospective analysis of PUV patients from 2006 to 2014. Data collected included demographics, initial renal ultrasound (RUS) findings, creatinine at presentation and nadir, pre- and postoperative VUR status, presence or absence of recurrent urinary tract infections (UTIs), and surgical intervention(s). Univariate and multivariate analyses were used to determine risk factors for renal failure. Of 104 patients, 42.3% (44/104) were diagnosed prenatally, 31.8% (14/44) of whom underwent prenatal intervention. Postnatally, 90.4% (94/104) initially underwent transurethral resection of PUVs (TUR-PUVs). Vesicostomy was the next most common index surgery (4.8%). Forty-two percent (44/104) required >1 surgery. The predominant second surgery was repeat TUR-PUV in 16 patients. At last follow-up (mean 28.8 months after initial surgery), 20.2% had chronic kidney disease (CKD) of at least stage IIIA, and 8.6% had progressed to end-stage renal disease (ESRD). Antenatal diagnosis, prematurity, abnormal renal cortex, and loss of corticomedullary differentiation (CMD) on initial RUS were associated with CKD and ESRD on univariate analysis, as were elevated creatinine on presentation and at nadir. Presence of pre- or postoperative VUR and recurrent UTIs were associated with the need for multiple surgeries, but not with poor renal outcomes. On multivariate analysis, nadir creatinine was the only independent predictor of final renal function. Our finding that creatinine is the only independent risk factor for poor renal outcomes in PUV patients is consistent with the

    Renal dysfunction is common during episodes of acute decompensated heart failure, and historical data indicate that the mean creatinine level at admission has risen in recent decades. Different mechanisms underlying this change over time have been proposed, such as demographic changes, hemodynamic and neurohumoral derangements and medical interventions. In this setting, various strategies have been proposed for the prevention of renal dysfunction with heterogeneous results. In the present article, we review and discuss the main aspects of renal dysfunction prevention according to the different stages of heart failure. PMID:23644863

    2015-04-01

    To describe the epidemiology, pathophysiology, diagnosis and management of perioperative acute kidney injury (AKI) in elderly patients. Elderly patients with a reduced renal reserve and multiple comorbidities have a higher risk of developing AKI after surgery. Postoperative AKI is diagnosed late and may even go undetected in immobilized elderly patients because of loss of muscle mass and reduced creatinine production. Panels of injury biomarkers could improve early risk stratification, but this approach needs further evaluation. The evidence for perioperative AKI prevention or treatment with renal vasodilators or remote ischaemic preconditioning is conflicting and needs further research. Avoiding hypotension, venous congestion and fluid overload appear important to protect elderly patients and their kidneys from harm. Continuous rather than intermittent renal replacement therapy should be considered early when the response to diuretics is insufficient to prevent fluid overload. Postoperative AKI incidence is expected to rise as the number of elderly patients undergoing surgery is increasing. Biomarkers of early AKI will likely be important for the future development and validation of novel treatment strategies. The haemodynamic management of the elderly surgical patient should focus on avoiding hypotension and high central venous pressures.

    Hyperuricemia is a common adverse event frequently found in renal transplant recipients with mizoribine (MZ). Hyperuricemia itself will be a cause of renal dysfunction, and renal dysfunction also will be a cause of hyperuricemia simultaneously. This study investigates frequency of hyperuricemia and renal failure in renal transplant recipients treated with high-dose MZ. From December 2007 to October 2015, there was a total of 32 living related renal transplant recipients treated with high-dose MZ. Of the 32 patients, 28 were treated with urate-lowering medications. One patient received allopurinol (AP) and 13 patients received benzbromarone (BB). For 6 of them, their urate-lowering medications were converted to febuxostat (FX) form AP or BB. In the remaining 14 patients, FX was administered from the beginning. In 2 cases of ABO-incompatible living related renal transplant recipients who were maintained with high-dose MZ and BB, severe hyperuricemia and acute renal failure occurred. One patient was a 48-year-old man, and his creatinine (Cr) level increased to 8.14 mg/dL and his serum uric acid (UA) was 24.6 mg/dL. Another patient was a 57-year-old man, and his Cr level increased to 3.59 mg/dL and his UA was 13.2 mg/dL. In both cases Cr and UA were improved, and no finding of acute rejection and drug toxicity was observed in graft biopsy specimens. BB was switched to FX and discontinuance or reduction of MZ was done. Combination of MZ and BB has the risk of acute renal dysfunction after renal transplantation. Latent renal dysfunction should be watched for in renal transplant recipients receiving high-dose MZ. Copyright © 2016 Elsevier Inc. All rights reserved.

    Dietary phosphorus is thought to be a factor that impairs the residual renal function in patients with chronic renal failure. To determine the effect of dietary phosphorus on the prognosis of chronic renal failure, low-phosphorus milk was prepared from normal cow's milk using boehmite, a synthetic phosphate-ion absorbent. Regular diet, normal cow's milk, and low-phosphorus milk were then given to 5/6-nephrectomized rats and the serum levels of inorganic phosphorus, calcium, creatinine, and blood urine nitrogen in the rats in each group were compared. The serum levels of inorganic phosphorus and calcium were not different among the groups, despite a significant difference in phosphorus intakes. On the other hand, serum levels of creatinine (Cr) and blood urine nitrogen (BUN) in the rats fed low-phosphorus milk were significantly lower (Cr, 0.54+/-0.054mg/dl; BUN, 29.2+/-3.90mg/dl) than those in the rats fed a regular diet (Cr, 0.64+/-0.057mg/dl; BUN, 37.4+/-3.55mg/dl) or normal milk (Cr, 0.61+/-0.040mg/dl; BUN, 34.5+/-3.59mg/dl). No beneficial effect of protein restriction was observed when residual renal functions in rats fed a regular diet and those fed normal milk were compared. The results suggest that dietary phosphorus plays a major role in the progression of renal failure.

    Full Text Available Introduction: Peptide levels in urine are found to be decreased in renal failure. 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.

    Full Text Available Acute renal failure can cause neurologic manifestations such as mood swings, impaired concentration, tremor, stupor, coma, asterixis, dysarthria. Those findings can also be a sign of cerebral infarct. Here, we report a case of watershed cerebral infarction in a 70-year-old female patient with acute renal failure secondary to contrast administration and use of angiotensin converting enzyme inhibitor. Patient was evaluated with magnetic resonance imaging because of dysarthria. Magnetic resonance imaging revealed milimmetric acute ischemic lesion in the frontal and parietal deep white matter region of both cerebral hemisphere which clearly demonstrated watershed cerebral infarction affecting internal border zone. Her renal function returned to normal levels on fifth day of admission (BUN 32 mg/dl, creatinine 1.36 mg/dl and she was discharged. Dysarthria continued for 20 days.

    Traditional herbal medicine is a global phenomenon especially in the resource poor economy where only the very rich can access orthodox care. These herbal products are associated with complications such as acute renal failure and liver damage with a high incidence of mortalities and morbidities. Acute renal failure from the use of herbal remedies is said to account for about 30–35% of all cases of acute renal failure in Africa. Most of the herbal medications are not usually identified, but some common preparation often used in Nigeria includes “holy water” green water leaves, bark of Mangifera indica (mango), shoot of Anacardium occidentale (cashew), Carica papaya (paw-paw) leaves, lime water, Solanum erianthum (Potato tree), and Azadirachta indica (Neem) trees. We report a rare case of a young man who developed acute renal failure two days after ingestion of Chinese herb for “body cleansing” and general wellbeing. He had 4 sessions of haemodialysis and recovered kidney function fully after 18 days of admission. PMID:26199625

    Full Text Available Acute renal failure (ARF in patients with malignancy occurs due to causes such as prerenal, renal and post renal as in normal population. Tumor infiltration of kidneys is usually uncommon. However, renal function may be impaired in fast-growing hematological malignancies such as acute leukemia or lymphoma, depending on tumor involvement. Herein, we presented a case of ARF and later diagnosed as B-cell Non-Hodgkin's lymphoma. 54-year-old male patient was admitted due to ARF. Although development of ARF due to tumor infiltration is rare, in cases who did not have risk factors for development of ARF, leukemic or lymphomatous infiltration should be considered.

    Acute renal failure (ARF) is a rare but potentially fatal complication of diabetic ketoacidosis (DKA). Early recognition and aggressive treatment of ARF during DKA may im-prove the prognosis of these patients. We present a case report of a 12 year old female admitted to the hospital with severe DKA as the 1s t manifestation of her diabetes mellitus. She presented with severe metabolic acidosis, hypophosphatemia, and oliguric ARF. In addition, rhabdomyolysis was noted during the course of DKA which probably contributed to the ARF. Management of DKA and renal replacement therapy resulted in quick recovery of renal function. We suggest that early initiation of renal replacement therapy for patients with DKA developing ARF may improve the potentially poor outcome of patients with ARF associated with DKA.

    Chronic kidney disease (CKD) is associated with a higher risk of stroke and atrial fibrillation (AF). There are limited data on the comorbidity of renal dysfunction and AF in stroke patients. Our aim was to determine the frequency of kidney dysfunction in ischaemic stroke patients with and without AF. In a prospectively collected, single center cohort of acute ischaemic stroke and transient ischaemic attack (TIA) patients, glomerular filtration rate (eGFR) was estimated using the Modification of Diet in Renal Disease equation on admission. Renal function was graded into five categories (cat.): cat. 1, eGRF ≥90 ml/min/1.73 m(2); cat. 2, 60-89; cat. 3, 30-59; cat. 4, 15-29; cat. 5, stroke, 547 TIA; median age 71.0) were included. Median eGFR was 78.6 ml/min/1.73 m(2) (interquartile range 61/95); 21.1% were in cat. 3, 2.1% in cat. 4, 0.7% in cat. 5. In all, 535 patients (23.5%) suffered from AF; 28.0% of these were in cat. 3, 2.6% and 0.8% in cat. 4 and cat. 5, respectively. In multivariable analysis, age [odds ratio (OR) 1.1], diabetes (OR 1.8), heart failure (OR 1.7) and AF (OR 1.4) were independently associated with kidney dysfunction (eGFR stroke patients than in the general population and more common in AF-related stroke. These findings may have implications for the choice of anticoagulants. © 2014 EAN.

    To investigate Tc-99m methylenediphosphonate (MDP) bone scan appearance in diabetic chronic renal failure patients, we compared the bone scan images of chronic renal failure patients with and without diabetes. The number of patients studied was 134, of whom 43 had diabetes. Two nuclear medicine physicians read Tc-99m MDP bone scan images and for six areas - the axial skeleton, long bone, skull and mandible, periarticular areas, costochondral junction, and sternum - assigned a score of either 1 or 0. The sums of scores were compared. We also performed multivariate analysis including sex, age, and serum creatinine level using analysis of covariance. DM group patients scored significantly lower (2.01±0.95) than those of the non-DM group (3.26±1.16). Analysis of covariance revealed that the lower DM group score was independent of sex, age, and serum creatinine level. The bone scans of diabetic chronic renal failure patients showed less Tc-99m MDP uptake than those of non-diabetic patients. Thus, diagnosing renal osteodystrophy in diabetic chronic renal failure patients on bone scan images could be difficult. (author)

    A prospective study of 82 patients with acute renal failure was carried out over the last 2 years. Mean age of the patients was 35.6 years (8-82 years). Male to female ratio was 3.5:1. The etiological factors were septicaemia in 18 patients (21.95%), aminoglycoside toxicity in 16 patients (19.51%), open heart surgery in 8 patients (9.76%), volume depletion and blood loss in 12 patients (14.63%), glomerulonephritis in 4 patients (4.88%), renal allograft dysfunction in 4 patients (4.88%), and miscellaneous causes in 20 patients (24.39%). Non-oliguric renal failure was observed in 39.02 per cent cases. Dialysis support was required in 65.8 per cent of the cases; with average 5.6 (4 to 11) dialysis sessions. Four patients of acute renal failure following open heart surgery were given continuous arterio-venous haemofiltration. Overall mortality was 32.5 per cent, septicaemia accounting for 60 per cent of the deaths.

    Full Text Available The patient was an 80-year-old man who arrived at the emergency room with breathing problems. He presented a history of chronic obstructive pulmonary disease (COPD, hypertension, diabetes mellitus and early (stage 1 chronic renal failure with normal levels of creatinine and no sign and symptoms of renal disease. A chest X-ray showed pneumonia. Therefore, he was first treated with 1 g daily of ceftriaxone IV. We did not observe any clinical improvement, and for this reason, a sputum culture was performed to guide the right antibiotic treatment. Subsequently, we started a new antibiotic therapy with trimethoprim/sulfamethoxazole (TMP/SMX adjusted to renal functioning. Appropriate medical treatment was administered, as well as urine alkalinisation. After the first day of treatment, the patient’s clinical and laboratory status worsened very quickly, with an increased level of serum creatinine from 1.5 to 3.5 mg/dL. We stopped administering the antibiotic therapy immediately. However, we observed acute renal failure with a serum creatinine level of 9.0 mg/dL and four days after his admission, the patient died. Literature showed that patients can develop acute kidney injury (AKI during or immediately following TMP/SMX therapy. Intrinsic renal impairment –rather, interstitial nephritis– appeared responsible for the great majority of cases, and impairment was transient if therapy was discontinued. In our study, despite the therapy with TMP/SMX was immediately discontinued, and our patient underwent appropriate medical treatment, urine alkalinisation and, then, haemodialysis, the AKI was rapidly fatal. In conclusion, particular attention should be paid to prescribing TMP/SMX to patients affected by 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....

    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.

    1977-01-01

    The role of renal hemodynamic alterations in the curtailment of renal function was studied in rabbits with uranyl acetate-induced acute renal failure. The day following the i.v. injection of uranyl acetate (2 mg/kg of body wt), renal blood flow (RBF) and clearance of creatinine (Ccr) decreased to approximately 60 and 20% of controls, respectively. Intracortical fractional flow distribution, estimated by radioactive microsphere method, did not change. The extraction ratio of para-aminohippurate (EPAH) decreased and the renal extraction of sodium (CNa/Ccr) increased, with minimal structural change in the kidney. Urine output increased two to three times that of the control. After three days oliguria appeared despite complete recovery of RBF. The zonal flow redistributed toward the deep cortex. CCr and EPAH reached their minimums, concomitantly with tubular necrosis and intratubular casts. After seven days animals could be divided into the oliguric and diuretic groups. CCr and EPAH were higher in the diuretic group, while there was no significant difference in RBF and the flow distribution between groups. Regeneration of damaged tubular cells was found in the diuretic group but not in the oliguric group. The findings suggest the minor roles of RBF and the intracortical flow distribution, and a fundamental role of back leakage of filtrate across damaged tubular epithelium in the maintenance of reduced CCR and urine output during the oliguric stage in rabbits with uranyl acetate-induced renal failure

    2012-02-03

    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.

    2008-06-01

    Full Text Available We report a case of acute renal failure in which renal biopsy showed immune complex-mediated proliferative glomeru-lonephritis. The patient had been afflicted with progressive lower back pain for 2 months. No fever was noted. Magnetic resonance imaging of the lumbar spine demonstrated characteristic findings of vertebral osteomyelitis and bilateral psoas abscesses. Culture of the computed tomography-guided needle aspirated specimens grew Staphylococcus aureus. The patient was treated with prolonged antibiotic therapy. The lower back pain improved gradually. Furthermore, significant improvement in renal function occurred approximately 2 weeks after the beginning of antibiotic treatment. The pathologic findings and clinical causal relationship between the bacterial osteomyelitis and the glomerulonephritis suggests a close association of the 2 conditions. Although glomerulonephritis is well documented to be related to a vari-ety of infectious diseases, its association with osteomyelitis has rarely been reported. We review the clinicopathologic characteristics of another 3 cases previously reported in the literature.

    In renal failure associated with the nephrotic syndrome, therapeutic strategy is highly dependent upon the cause of the renal failure. Dynamic hippurate scintigraphy was studied in five pediatric patients. Four had nephrotic syndrome, and of these, three had acute renal failure. The fifth patient had end-stage renal failure. Specific alteration in renal hippurate kinetics offers a noninvasive assessment of renal failure in this clinical setting

    Twelve patients with acute renal failure underwent L.dopa infusion into a renal artery and 133 Xenon wash-out recordings before and during the infusion. Urine volume and sodium output were also compared during two 24 hours periods, before and after the procedure. Hemodynamic data were compared with data obtained from a matched group of patients receiving Furosemide (8 patients) in place of L.dopa. Only L.dopa infusion significantly increased outer cortical distribution. No blood flow change could be demonstrated in any component nor did the drug improve unitary excretion or the general course of the disease. Control data shows that reduced cortical distribution is the most consistent feature of acute renal failure, so that L.dopa does partially improve intrarenal hemodynamics in this condition. The failure of the drug to restore kidney function may be explained by the following reasons: inability of the agent to restore a normal wash-out pattern: involvment of non-hemodynamic factors, as suggested by comparing similar wash-out improvements after L.dopa in acute glomerulonephritis and in reversible acute renal failure [fr

However the exact mechanism by which CKD impairs the cardiovascular outcome is not well established. Some reasons may lie in the association of CKD with several other cardiovascular and noncardiovascular disorders including accelerated systemic atherosclerosis, endothelial dysfunction, increased levels of inflammatory factors, anemic status, bone mineral dysfunction, electrolyte imbalance, and renin–angiotensin–aldosterone system (RAAS activation. Therefore several risk factors such as hypertension, diabetes, lipid disorders, and older age are common in both conditions. In patients affected with heart failure (HF a key role is represented by the neurohormonal activation. This condition causes fluid and sodium retention, peripheral vasoconstriction, as well as increased congestion and cardiac workload. Moreover, HF during the decompensated phases is often associated with a worsening renal function that leads to further RAAS activation, microvascular damage, and intrarenal flow redistribution. In order to clarify the interactions between these factors, several questions need to be answered: the universal definition of “worsening renal function,” the identification of the best laboratory parameters to investigate renal function in terms of sensitivity and specificity, and a better definition of the comorbidities’ role in the determination of the outcome, especially in patients with chronic HF. A clarification of these key points could lead to the individualization of new specific therapeutic targets and to a reduction in mortality and hospitalization in patients with HF and

    A 12-year-old Congolese girl presented with acute renal failure, edema, hypertension, hemoptysis, hematuria, and proteinuria after a history of throat infection. Renal ultrasound showed kidneys of normal size, with increased echogenicity of the cortical parenchyma and decreased corticomedullary differentiation. Other additional investigations showed pancytopenia with decreased complement (low C3 and C4). Antinuclear antibodies were strongly positive, including anti-double stranded DNA. Renal biopsy confirmed severe grade IV lupus nephritis. She was treated with high-dose steroids, mycophenolate mofetil and hydroxychloroquine, in addition to hemodialysis. After one week of intensive treatment, diuresis recovered and dialysis could be stopped after six sessions. We describe an uncommon case of severe lupus nephritis, presenting with terminal renal failure. Since the rarity of this disease presentation, other more common diagnoses have to be considered. Once the diagnosis of lupus nephritis is established, a choice has to be made between the different induction treatment protocols. The patient's ethnic background and other supportive therapies, such as the need for dialysis, can help to make this choice.

    Renal insufficiency is associated with the prognosis of acute ischemic stroke (AIS) and homocysteine (Hcy) levels. This study investigated the association between plasma Hcy levels and renal insufficiency in patients with AIS. A total of 987 patients with AIS who had been treated at the First People's Hospital of Foshan between 2011 and 2014 were retrospectively studied. Based on their cystatin C (Cys C) levels, the patients were divided into the normal renal function group (Cys C ≤ 1.25 mg/L) or the renal impairment group (Cys C > 1.25 mg/L). Multivariate regression analysis was applied to reveal the association between hyperhomocysteinemia (HHcy) and renal impairment. The renal impairment group showed more advanced age of onset, higher percentage of prior stroke and hypertension, higher baseline National Institute of Health Stroke Scale score, lower high-density lipoprotein cholesterol levels, and higher Hcy levels compared with the normal renal function group. A multivariate analysis revealed a relationship between early renal impairment and Hcy levels: an increase of Hcy by 1 μmol/L was associated with an increase of 12-18% of the risk of renal impairment among patients with AIS and HHcy. Patients with AIS and HHcy had a 2.42-3.51 fold increase of the risk of renal impairment compared with patients with normal Hcy level (P renal impairment.

    A 66-year-old diabetic man presented with severe right thigh swelling and pain together with acute renal failure. At autopsy, this was found to be due to disseminated high grade B cell lymphoma invading the psoas muscle and multiple organs, including the kidneys. The unique presentation of this case emphasizes the need for increased awareness of the variety of ways in which lymphoma can manifest itself.

    Full Text Available Thyroid hormone level may be altered in chronic renal failure patients. Low levels of thyroxine protect the body from excess protein loss by minimizing catabolism. Hyperthyroidism is rarely encountered in end-stage dialysis dependent patients. Less than 10 well-documented cases of Graves′ disease (GD are reported in literature so far. We report a case of GD in a patient on dialysis.

    Objective: To explore the relationship between chronic renal failure and serum leptin levels in patients with chronic renal failure. Methods: Serum leptin levels (with RIA) were determined in 134 patients (male, 73, female 61) with chronic renal failure and 40 controls. Results: The serum levels of leptin in the chronic renal failure group were significantly higher than those in the controls (t=2.39, P<0.01). There were no significant differences among the leptin levels in patients with different stages of renal failure. Conclusion: There were hyper-leptinemia and leptin resistance in patients with chronic renal failure. The increase of leptin levels is thought to be harmful in patients with chronic renal failure, however, the precise mechanism remains to be studied further. (authors)

    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.

  9. A Medical Mystery: Unexplained Renal Failure in Burn Patients.

    Lands, Harrison M; Drake, David B

    The objective of this study was to review the investigation that uncovered the medical mystery of burn patients developing unexpected renal failure. The authors examined published and unpublished manuscripts and case reports, as well as conducted personal interviews with primary sources. In the late 1970s, emergence of resistant bacterial strains to the topical antimicrobial silver sulfadiazine occurred at the University of Virginia Medical Center. In the search for an alternative topical antimicrobial with known coverage of Pseudomonas aeruginosa, Furacin Soluble Dressing was substituted. However, Furacin Soluble Dressing produced an unexpected toxicity syndrome of hyperosmolality, metabolic gap acidosis, hypercalcemia, and ultimately renal failure. In a search for an antimicrobial with an improved spectrum against Pseudomonas, a Federal Drug Administration-approved product was used to treat large surface area burns. An unexpected toxicity syndrome developed which was traced to the polyethylene glycol base of Furacin Soluble Dressing. This substance was absorbed through the burn wounds, metabolized, and resulted in a toxicity syndrome leading to renal failure. The burn community should be cautious when using products that may be approved as nontoxic for small surface area application, as they may have unexpected medical side effects when used with large surface area burns.

    Despite the progress in animal research concerning the pathophysiology and the progress in clinical practice regarding the methods of therapy, the incidence and mortality of acute renal failure remain high, especially when other organs are involved. New pharmacological interventions have led to the perspective that in the near future it may be possible to prevent and/or ameliorate this devastating syndrome. Continuous dialysis therapy and the selection of a biocompatible membrane may possibly help the critically ill patient especially when parenteral nutrition and correction of electrolyte and acid-base disturbances are important. Nevertheless, more solid data are needed and one should take into consideration that acute renal failure is a multifactorial syndrome. The type of dialysis itself is not the only matter which has to be evaluated since the mortality rate can be correlated with the number of involved organs before or after the initiation of acute renal failure and with the severity of the original disease. In clinical practice, a large number of prospective studies and more sophisticated statistical methodology are needed in order to evaluate the proper treatment modality.

    We experienced two esophageal cancer patients who developed severe acute renal failure after neoadjuvant chemotherapy with cisplatin and 5-fluorourasil. After administration of cisplatin, their serum creatinine increased gradually until they required hemodialysis and their renal failure was permanent. In both cases, renal biopsy examination indicated partial recovery of the proximal tubule, but renal function did not recover. After these events, one patient underwent definitive radiotherapy and the other underwent esophagectomy for their esophageal cancers, while continuing dialysis. Both patients are alive without cancer recurrence. In these two cases of cisplatin-induced renal failure, renal biopsy examination showed only slight disorder of proximal tubules and tendency to recover. Although cisplatin-related nephrotoxicity is a well-recognized complication, there have been few reports of renal failure requiring hemodialysis in cancer patients. In this report, we present their clinical courses and the pathological findings of cisplatin-related renal failure. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Full Text Available Tenofovir is an acyclic nucleotide analogue reverse transcriptase inhibitor that is commonly prescribed as part of a highly active antiretroviral therapy (HAART regimen in HIV-infected patients. Although it is generally well tolerated, renal insufficiency has been associated with its use. We report a biopsy-proven case of acute renal failure that developed within weeks of initiating a HAART regimen containing tenofovir, and review the literature with specific attention to cases of renal failure occurring within 8 weeks of tenofovir initiation. Our patient developed renal insufficiency within 3 weeks of initiating tenofovir-containing HAART and overt renal failure was noted within 5 weeks. Renal biopsy demonstrated histopathologic changes suggestive of HIV nephropathy, despite normal baseline serum creatinine values. Thirty additional cases of tenofovir-associated renal failure have been reported. In the majority (n = 22, 73%, renal failure occurred months after initiating therapy (range: 5–26 months. However, in a significant subset (n = 8, 27%, renal failure occurred within 8 weeks of treatment initiation. Our data suggest that some patients are at risk for developing renal failure within weeks of tenofovir initiation. Thorough evaluation of renal function should be undertaken before prescription of tenofovir-containing HAART. For those in whom subclinical renal disease is discerned, added vigilance when monitoring renal function may be warranted.

    Full Text Available Euphorbia paralias is known in traditional medicine as an anti-inflammatory agent, a purgative and for its local anesthetic property. To the best our knowledge, renal toxicity of this substance has not been previously reported. In this paper, we report the case of a 29-year-old male who developed renal damage following ingestion of Euphorbia paralias. He had been on follow-up for nephrotic syndrome since 1986, although irregularly, with several relapses but each responding well to steroid therapy. A kidney biopsy had not been performed earlier due to refusal by the patient. He was off steroids since April 2008 because the patient developed osteoporosis. He was admitted with general malaise and oliguria to our department in May 2009, following repeated vomiting and watery diarrhea for three days. On examination, he was edematous but had normal vital signs except for a pulse rate of 120/min. Hemoglobin was only 5.5 g/dL but with normal white cell and platelet counts. Blood biochemistry showed evidence of advanced renal failure with a serum creatinine level of 1835 μmol/L and urea at 44.6 mmol/L, sodium of 132 μmol/L and potassium at 4.3 mmol/L. He had features of nephrotic syndrome with severe hypoproteinamia and 24-h urinary protein of 10.45 g. Ultrasonography revealed enlarged kidneys with a reduced echogenecity of the medulla and the papillae. Subsequently, after hemodialysis with blood transfusion, a kidney biopsy was performed that showed focal segmental glomerulosclerosis associated with an acute tubular injury. On intensive interrogation, the patient gave a history of ingesting boiled Euphorbia paralias as a native treatment for edema, ten days prior to the onset of the current illness. A diagnosis of acute renal failure (ARF resulting from the possible nephrotoxic effect of Euphorbia paralias poisoning was made. He was treated with intermittent hemodialysis and corticosteroids. Serum creatinine values improved after 48 days. At six

    Full Text Available Abstract Background Secondary involvement of the thyroid gland by malignant metastases is uncommon. Acute respiratory crisis due to infiltration of the upper airways is a recognised complication of anaplastic thyroid carcinoma or thyroid lymphoma. Renal cell carcinoma is a tumour that metastasizes diffusely and in an unpredictable manner. Case presentation We report a case of a 73-year-old man with a painful neck mass, dyspnoea, stridor and dysphonia that was evaluated in emergency. A right radical nephrectomy for renal cell carcinoma was performed 8 years previously. An emergency endotracheal intubation was followed by total thyroidectomy. Histological examination confirmed the diagnosis of thyroid metastasis from renal cell carcinoma. Conclusion A literature review regarding emergency treatment for acute respiratory compromise resulting from secondary thyroid tumours was undertaken. Only two cases of metastatic colon cancer and one case of metastatic meningioma requiring emergency thyroidectomy for acute respiratory failure are reported in the literature. This appears to be the first case of emergency surgery performed for acute respiratory compromise due to thyroid metastasis from renal cell carcinoma.

    In a press conference at the House of Commons, medical consultants admitted that their hope to elicit additional funds from the government for treatment of renal failure is tied to their ability to relate the inadequacy of treatment resources to lack of money. However, such a campaign makes physicians distant from renal treatment centers unwilling to refer candidates since they believe treatment may be denied. The consultants contend that the establishment of satellite units is the best solution. Expansion of facilities and improvement of the referral rate must go hand in hand. Other problems include the inability of centers to pay staff to operate more efficient dialysis equipment which can be utilized around the clock, and the high cost of the immunosuppressant drug, cyclosporin.

    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...... (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...... 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....

    1980-04-01

    After a strenuous indoor competition, a 24 year old male 400 meter runner experienced severe back pain followed by three days of nausea and vomiting. This led to hospital admission with oliguria, serum creatinine of 12.6 mg%, and BUN of 72 mg%. Peritoneal dialysis was given for 96 hours and was discontinued when the diuretic phase developed. Myoglobinuria was suspected, but all tests for it were negative. Mechanisms of acute tubular necrosis are reviewed, noting predisposing factors-dehydration, acidosis, and hypoxia-which were present in this clinical case. Ischemia due to markedly reduced renal blood flow secondary to mass sympathetic discharge, dehydration and metabolic acidosis could cause sufficient tissue damage to trigger acute renal failure in the presence of myoglobinemia. Active fluid replacement in athletic training and competition is stressed as a preventive feature.

    The first results concerning the use of renal scintigraphic scanning using hippuran in acute renal failure (A.R.F.) are presented. The tubular stages of hippuran, extraction and secretion then excretion correspond to phenomena which are normally apparent within the first 10 minutes following the injection of hippuran, also it seemed interesting to study the changes which occur in A.R.F. 18 hospital in-patients with A.R.F. were studied, 10 of them suffering from tubulo-interstitial nephropathy (T.I.N.) 4 with acute glomerulonephritis (A.G.N.), 2 with obstruction of the urinary pathways and 2 with tubular necrosis on underlying chronic renal failure. In the 10 cases of T.I.N. the phenomenon of extraction was evident without any sign of secretion appearing during the 24 minutes of the investigation. No relationship could be found between the scintigram and the rapidity of recovery from A.R.F., but 8/10 recovered satisfactory renal function, the two others died from their disease, the A.R.F. being only secondary. It seems that the presence of an extraction phenomenon, whatever the aetiology of the A.R.F., is a parameter which authorizes the prognosis of a favorable course whereas its absence during the 24mm, of the investigation permits one to envisage an unfavorable course [fr

  20. Na+-K+ pump in chronic renal failure

    Deepak, K.; Kahn, T.

    1987-01-01

    This review summarizes the evidence for the defect in Na + -K + pump in chronic renal failure, considers the role of various factors in causing this defect, and discusses the clinical implications thereof. Intracellular Na is elevated in erythrocytes, leukocytes, and muscle cells from some patients with chronic renal failure (CRF). Recent evidence suggest that this elevation of cell Na may be, in large part, a consequence of decreased number of Na + -K + pump units per cell. Maintenance dialysis over a period of weeks ameliorates the defect in intracellular Na + , and this improvement is contemporaneous with an increase in the number of Na + -K + pump sites per cell. In erythrocytes with normal cell Na + , acute hemodialysis increases the rate of 22 Na + and 42 K + transport. Many factors such as the presence of retained toxic metabolite or circulating inhibitor in the uremic plasma, or biochemical changes produced by acute hemodialysis, may explain this finding. In cells with high cell Na + , the pump-mediated 42 K + transport is normalized at the expense of a raised cell Na + . The decreased muscle membrane potential in uremic subjects has been attributed to a decreased activity of Na + -K + pump. The authors discuss the role of hormonal abnormalities and circulating inhibitors, which may cause an acute inhibition of the pump and of other factors such as K + depletion, which may cause more chronic alterations. The implications of alteration of Na + and K + pump transport and raised cell Na + on other non-pump-mediated transport pathways are discussed. Raised cell Na + may be a marker for the adequacy of maintenance dialysis in patients with end-stage renal failure

    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.

    2016-07-01

    Acute renal failure (ARF) in adults in the intensive care unit (ICU) often evolves in a context of multiple organ failure, which explains the high mortality rate and increase treatment needs. Among, two modalities of renal replacement therapy, peritoneal dialysis (PD) was the first modality used for the treatment of ARF in the 1950s. Today, while PD is generalized for chronic renal failure treatment, its use in the ICU is limited, particularly, due to the advent of new hemodialysis techniques and the development of continuous replacement therapy. Recently, a renewed interest in the use of PD in patients with ARF has manifested in several emerging countries (Brazil, Vietnam). A systematic review in 2013 showed a similar mortality in ARF patients having PD (58%) and those treated by hemodialysis or hemodiafiltration/hemofiltration (56.1%). In the International society of peritoneal dialysis (ISPD)'s guideline (2013), PD may be used in adult ARF as the other blood extracorporeal epuration technics (recommendation with grade 1B). PD is the preferred method in cardiorenal syndromes, in frailty patients with hemodynamic instability and those lacking vascular access; finally PD is also an option in elderly and patients with bleeding tendency. In industrial countries, high volume automated PD with a flexible catheter (usually Tenckhoff) is advocated. Copyright © 2016 Association Société de néphrologie. Published by Elsevier SAS.

    Renal involvement in some forms of acute or chronic diseases, such as heart failure or sepsis, presents with a complex pathophysiological basis that is not always clearly distinguishable. In these clinical settings, kidney failure is traditionally and almost exclusively attributed to renal hypoperfusion and it is commonly accepted that causal elements are pre-renal, such as a reduction in the ejection fraction or absolute or relative hypovolemia acting directly on oxygen transport mechanisms and renal autoregulation systems, causing a reduction of glomerular filtration rate. Nevertheless, the concept emerging from accumulating clinical and experimental evidence is that in complex clinical pictures, kidney failure is strongly linked to the hemodynamic alterations occurring in the renal venous micro and macrocirculation. Accordingly, the transmission of the increased venous pressure to the renal venous compartment and the consequent increasing renal afterload has a pivotal role in determining and sustaining the kidney damage. The aim of this review was to clarify the physiopathological aspects of the link between worsening renal function and renal venous hypertension, analyzing the prognostic and therapeutic implications of the so-called congestive kidney failure in cardio-renal syndrome and in other clinical contexts of its possible onset.

    Full Text Available Introduction: Perinatal asphyxia (PA results in hypoxic damage to almost all organs, kidneys being most frequently (40% affected. Objectives: was to determine the incidence of acute renal failure (ARF in term neonates with PA and to correlate it with severity of hypoxic ischemic encephalopathy (HIE. Materials and methods: This prospective study of 54 term neonates with PA was performed in tertiary level neonatal intensive care unit at Pediatric Clinic Sarajevo from June 2014 to June 2016. The severe PA was defined as 5. minute Apgar score 1.5 mg/dl (>133 micromol/L on 3rd day of life or urine output 6 hrs beyond 24 hrs of life. Results. Out of 54 neonates with PA, 22 (40.74 % had ARF. Most of them (63.6% had non-oliguric ARF with mean renal output of 2.2 ± 0.5 ml/kg/h. Eight neonates (36.4% had oliguric ARF with mean renal output of 0.35 ± 0.6 ml/kg/h. Most of the neonates with oliguric ARF (63.4% had severe PA while in those with non-oliguric ARF moderate PA was predominant. ARF was highest in the neonates with HIE III (85.71 %. (Figure 1.. This showed that as HIE stage progressed, more renal dysfunction was seen in asphyxiated babies and this difference in incidence was found statistically significant (p<0.05. Conclusions. Neonates with severe PA had more frequent ARF and the predominant type of renal involvement was non oliguric. Neonates with HIE stage II and III had significantly higher incidence of ARF.

    Full Text Available Acute renal failure (ARF is a rare complication of acute pyelonephritis in adult immunocompetent patients. Recovery of renal function usually occurs if antibiotics are promptly initiated. However, long-term consequences of renal scarring due to acute pyelonephritis are probably underestimated, and some patients present with prolonged renal failure despite adequate antibiotic therapy. We report two cases of severe ARF complicating bacterial pyelonephritis successfully treated with corticosteroids in association with conventional antibiotics.

    We describe a 45-year-old patient who was diagnosed with propionic acidemia in infancy, who experienced an unstable first two years of life but who eventually had a good developmental outcome. She developed severe renal failure requiring renal transplantation in her forties and premature ovarian failure. Renal failure and premature ovarian failure have not previously been associated with propionic acidemia. We hypothesize that propionic acidemia may have contributed to these complications, and discuss several possible mechanisms for this, emphasizing mainly the electron transport chain/mitochondrial energy deficiency hypothesis.

    New reliable oxidative stress markers are present in chronic renal failure (CRF) patients, indicating that CRF is a pro-oxidant state. However, the pathogenesis of oxidative stress in CRF patients remains poorly defined. Moreover, the limited data available provide no clear-cut evidence in favor of the clinical benefit of antioxidant manoeuvres aimed at reducing cardiovascular disease in CRF patients or in the general population as well. Therefore, no practical recommendations can be given at this stage, and further studies are clearly needed.

    Controversies still exist about the use and the effects of low protein diets in chronic renal failure. The contrasting - sometimes opposite - results published over the last 30 years in several studies can be read and explained by a series of errors included in those studies. The new Comedy of Errors starts from the misinterpretation of experimental studies, the lack of appropriacy of clinical trials' design; it continues with neglecting the role of patients' compliance as well as of other clinical findings, here included the role of blood pressure. Finally pitfalls in the intrepretation of the results of clinical trials and meta-analyses were identified.

    Full Text Available Wolfram′s syndrome is usually considered as an autosomal recessive condition, with wide phenotypic variation. The syndrome is commonly called DIDMOAD (diabetes insipidus, diabetes mellitus, optic atrophy and deafness, although some patients have additional clinical findings including ataxia, hypogonadism, hydronephrosis and psychiatric illnesses. We report a patient with DIDMOAD syndrome with emphasis on the urological tract and its progressive complications. Unfortunately, he developed end-stage renal failure and needed hemodialysis at the age of 14 years. The presentation, investigations and management are discussed.

    To estimate whether the reported increase in obstetric acute renal failure in the United States was attributable to a concurrent rise in postpartum hemorrhage, a change in other risk factors, or changes in the diagnosis of acute renal failure. We conducted a retrospective cohort study to quantify temporal trends in acute renal failure among 10,969,263 hospital deliveries in the United States from 1999 to 2011 using data from the Nationwide Inpatient Sample. Dialysis and maternal death were used as markers of severe acute renal failure. Logistic regression was used to determine whether changes in risk factors explained the temporal rise in acute renal failure. Obstetric acute renal failure rose from 2.4 to 6.3 per 10,000 deliveries between 1999-2001 and 2010-2011, a 10% yearly increase (95% confidence interval [CI] 8-11%) and adjustment for risk factors only partially explained the rise (adjusted yearly increase 6%, 95% CI 5-8%). The overall severity of acute renal failure decreased, although acute renal failure with dialysis rose from 0.27 to 0.36 per 10,000 deliveries (P for trend=.01), and acute renal failure associated with maternal death increased from 0.13 to 0.23 per 10,000 deliveries (P for trend=.01). The temporal increase in acute renal failure with dialysis was abolished by adjustment for chronic kidney disease and chronic hypertension. Changes in diagnosis or ascertainment have led to substantial increases in obstetric acute renal failure, whereas increases in chronic kidney disease and chronic hypertension among pregnant women have resulted in modest but significant increases in acute renal failure with dialysis.

    Full Text Available Rhabdomyolysis and myoglobinuria are a rare complication of dermatomyositis. Such patient can land up in acute renal failure. Recognition of this fact has important therapeutic implications as patients require immunotherapy in addition to the symptomatic treatment for renal failure. We report a case of dermatomyositis with evidence of rhabdomyolysis and myoglobinuria presenting with acute renal failure. The patient responded dramatically to corticosteroid therapy.

    Acute renal failure (ARF) is a rare (2-15%), but severe complication of cardiac surgery with overall mortality reaching 40-80%. In order to save patients' lives they are treated with renal replacement therapy (RRT). The aim of our study was to assess the impact of different perioperative factors on mortality among patients treated with RRT because of acute renal failure, which occurred as a complication of a heart surgery. Retrospective analysis included 45 patients, operated in the years 2009-2013, who underwent renal replacement therapy in order to treat postoperative ARF. The perioperative factors were analysed in two groups: group 1 - patients who died before discharge; and group 2 - those who survived until hospital discharge. Forty-five of 3509 cardiac surgical patients (1.25%) required RRT after the surgery. A total of 23 (51.11%) died before discharge (group 1). Patients in group 1 were characterised by older age (70.21 vs. 67 years), higher mean EuroSCORE value (9.28 vs. 7.15) (p < 0.05), higher percentage of concomitant surgery (63.63% vs. 28.57%) (p < 0.05) and of admission of catecholamines in the postoperative period (100% vs. 68.42%) (p < 0.005), and higher mean urea blood level prior to RRT initiation (156.65 vs. 102.54 mg/dl) (p < 0.05). The statistically relevant death predictors proved to be: high EuroSCORE, concomitant surgery, and high urea level at RRT initiation and admission of catecholamines in the postoperative period. After conformation in further studies, those factors may prove useful in stratification of death risk among surgical patients requiring RRT.

    In patients with cardiovascular disease (CVD), renal dysfunction is a risk factor for the prognosis, but substantial evidence is still lacking about the relationship between clinical characteristics and renal histology. The aim of our study was to evaluate the relationship between the extent of renal parenchymal damage, renal artery stenosis (RAS) and clinical characteristics in autopsy subjects with stroke. During the 17-year period 1980-1997, 2167 subjects were autopsied at the National Cardiovascular Center. We studied retrospectively all the autopsy cases aged 40 years and older who had a history of stroke. Thus, 346 subjects remained and they were classified into two groups. Thirty-six subjects had RAS (group A). Three hundred and ten subjects had no RAS, and we randomly chose 102 subjects among them (group B). We evaluated renal parenchymal damage using a semi-quantitative chronic damage score. The average overall chronic damage score was significantly higher in the stenosed kidneys of group A than in the non-stenosed kidneys of group B (9.0+/-2.6 vs 7.0+/-2.7). The contralateral kidneys of group A had a tendency to have milder renal damage than stenosed kidneys. Furthermore, the total score was higher in the subjects with hypertension, diabetes mellitus, proteinuria, renal insufficiency and CVD than in the subjects without such complications. The total score had a significant association with RAS, proteinuria, renal insufficiency, CVD and weight of the kidney. In autopsy subjects with stroke, we demonstrated that co-existing renal parenchymal damage was more severe in the subjects with RAS, hypertension, diabetes mellitus, proteinuria and renal insufficiency than those without such complications. The presence of RAS, impaired renal function and proteinuria was closely correlated with the severity of renal parenchymal damage.

    The relationship between serum uric acid (SUA) levels and stroke is controversial. The discrepancies in the results could be due to the uneven setting of comorbidity. It is known that hyperuricaemia increases in parallel with the decline in renal function; however, there are few studies that adjust for renal disease. To investigate the relationship between SUA levels in the acute phase of ischaemic stroke according to the presence or absence of chronic kidney disease and clinical outcomes during admission. Retrospective cross-sectional analysis of patients recruited through a unicentric stroke registry. The sample was divided according to its quartiles of SUA. Renal disease was defined based on the haematocrit, urea and Gender (HUGE) formula. The outcome was determined by the National Institutes of Health Stroke Scale (NIHSS) score. Statistically robust methods were used with R (version 3.3.2). A total of 412 patients (53.8% male) were analysed. The NIHSS score decreased as the SUA levels increased (p function (p stroke (OR = 0.67, 95% CI 0.51-0.88, p = 0.004). Our results support the hypothesis that hyperuricaemia plays a protective role in the prognosis of stroke, independently from renal function, and that even in patients with chronic kidney disease, it remains as a protective agent.

    Full Text Available Objective: to study the causes of acute renal failure (ARF in children and to substantiate recommendations on its treatment. Fifty-nine children with ARF were followed up in 1979 to 2004. In 90% of the patients, ARF was established to be caused by hemolytic uremic syndrome (HUS, acute intestinal infection (AII, acute glomerulonephritis, and acute intravascular hemolysis. The major cause of ARF was AII in two thirds (66.1% of the children. In the past decade, the incidence of HUS has decreased from 55 to 40%. The authors identified the following predictors of poor ARF outcome: early age, anuria, impaired consciousness progressing to spoor and coma. A combination of these symptoms is most frequently observed in patients with HUS in which the kidneys are the major target organ and the possibilities of more than 7-day treatment for anuria without dialysis are limited. In other etiology of ARF, water deprivation, antihypertensive therapy, and exchange plasmapheresis allow patients to survive until renal function restores without renal replacement therapy, by preventing serious complications. 

  18. Oral disorders in patients with chronic renal failure. Narrative review

    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.

    Purpose/objective: To identify the pattern of failure in patients with resected renal cell carcinoma (RCC). Materials and Methods: The records of 116 patients with unilateral non-metastatic RCC, who were treated with definitive surgery and referred to the Ottawa Regional Cancer Centre between 1977 and 1988, were reviewed. Distribution by stage included: T1 = 3 patients, T2 = 42 patients, T3 =71 patients. The median follow-up was 44 months, with a range of 4-267 months. Results: Loco-regional failure (LRF) developed in 8 patients, yielding a 7-year actuarial incidence of 8% for LRF, as first event. Nine patients developed local or regional recurrence + distant failure, and 58 patients had distant metastases only. Seven-year actuarial incidence of distant failure was 55%. The overall 7-year actuarial survival rate was 40%, and cause-specific survival was 45%. Conclusion: LRF was rare following nephrectomy. This data does not support the role of adjuvant radiation therapy in this disease

    The goal of this study is to assess the effect of cardiac resynchronization therapy (CRT) over time on renal function and its impact on mortality. The effect of CRT on renal function in patients with heart failure is not well understood. All patients who underwent CRT implantation at University of Kansas between year 2000 and 2009 were reviewed and patients who had pre and post CRT renal function studied were included in our study. Stages of chronic kidney disease (CKD) were defined based on Kidney Disease Outcome Quality Initiative (KDOQI) guidelines. The effect of CRT on renal and cardiac function were studied at short term (≤6 months post implantation) and long term (>6 months). A total of 588 patients with mean age of 67 ± 12 yrs were included in the study. CRT responders (defined by increase in LVEF ≥ 5%) were 54% during short term follow-up and 65% on long term follow-up. When compared to baseline, there was no significant deterioration in mean Glomerular Filtration Rate (GFR) during follow up. When analyzed based on the stages of CKD, there was significant improvement of renal function in patients with advanced kidney disease. Multivariate logistic regression analysis showed that stable GFR or an improvement in GFR independently predicted mortality after adjusting for co-morbidities. CRT was associated with stabilization of renal function in patients with severe LV dysfunction and improvement in stage 4 and 5 CKD. Improved renal function was associated with a lower mortality.

    Since total homocysteine (Hcy) is markedly elevated in patients with chronic renal failure (CRF), it has been presented as potential factor contributing to the high risk of cardiovascular disease (CVD) in CRF. The aim of the study was to examine the significance of elevated Hcy and other cardiovascular risk factors for carotid atherosclerosis in patients with CRF. Fifty six patients 16-M, 40-F, average age 58+/-14.55, creatinine clearance 39.19+/-10.11 ml/min were examined. In addition, 20 control healthy subjects were examined. The association of Hcy levels and classic risk factors for atherosclerosis with common carotid intima-media thickness (IMT) was examined. B-mode ultrasound measurement of carotid IMT was performed in 56 hypertensive pts with CRF (glomerular filtration rate>20 ml/min and 0.05). Significant predictors for IMT were age (r=0.358, p<0.04), duration of hypertension (r=0.395, p=0.023), diabetes duration (r=0.343, p<0.02), as well as duration of CRF (r=0.324, p<0.006). There was a negative correlation between IMT and glomerular filtration rate assessed by creatinine clearance (r=-0.303, p<0.003). Renal function, described by creatinine clearance was the strongest determinant for Hcy levels (r=-0.332, p<0.008). Increased IMT was estimated in pts with CRF compared to healthy controls (0.74+/-0.10 vs 0.59+/-0.10, p<0.001). We found association between Hcy and carotid IMT ( r=0.344, p<0.015). No consistent association was found between IMT and other specific for CRF cardiovascular risk factors. The study suggests that patients with mild renal failure have increased IMT of the common carotid artery and that elevated plasma Hcy level in CRF is associated with carotid intima- media thickening.

    Full Text Available Acute renal failure is a frequent entity in the elderly. This is due on one hand to the structural and physiological changes of the aged kidney, and on the other hand to the exposure of this population to polypharmacy and their reduced capability to metabolize drugs. In the present report we present a case of a seventy year-old woman who developed acute renal failure secondary to severe dehydration with a clinical and laboratory pattern of intermediate syndrome: laboratory results compatible with parenchymal renal insufficiency (elevated urinary sodium, plasma urea and creatinine, but with a positive response to hydration. The main characteristics of the aged kidney that predispose to the development of an intermediate syndrome are: the vascular dysautonomy and reduced capability of sodium and water reabsorption. The intermediate syndrome is a typical pattern of pre-renal insufficiency in the elderly. RESUMEN: La insuficiencia renal aguda es frecuente en el anciano. Esto se debe por un lado a los cambios estructurales y funcionales propios del riñón senil, y por otro a la gran exposición que esta población tiene a la polifarmacia, y su reducida capacidad para metabolizar los medicamentos. En este reporte presentamos el caso de una mujer de 70 años que desarrolló una insuficiencia renal aguda secundaria a severa deshidratación, mostrando un patrón clínico y de laboratorio propio de un sindrome intermedio: laboratorios compatibles con una insuficiencia renal parenquimatosa (sodio urinario, uremia y creatininemia elevadas, pero con una respuesta favorable a la hidratación. Las principales características del riñón senil que predisponen al desarrollo del sindrome intermedio: son la disautonomía vascular y la reducida capacidad en la recuperación de sodio y agua El sindrome intermedio es un patrón típico de insuficiencia prerrenal en el anciano.

  4. Mechanism-Based Therapeutic Approaches to Rhabdomyolysis-Induced Renal Failure

    2010-01-01

    Rhabdomyolysis-induced renal failure represents up to 15% of all cases of acute renal failure. Many studies over the past four decades have demonstrated that accumulation of myoglobin in the kidney is central in the mechanism leading to kidney injury. However, some discussion exists regarding the mechanism mediating this oxidant injury. Although free iron-catalyzed fenton reaction has been proposed to explain the tissue injury, more recent evidence strongly suggests that the main cause of oxidant injury is myoglobin redox cycling and generation of oxidized lipids. These molecules can propagate tissue injury and cause renal vasoconstriction, two of the three main conditions associated with acute renal failure. This review presents the evidence supporting the two mechanisms of oxidative injury, describes the central role of myoglobin redox cycling in the pathology of renal failure associated with rhabdomyolysis, and discuss the value of therapeutic interventions aiming at inhibiting myoglobin redox cycling for the treatment of rhabdomyolysis-induced renal failure.

    Full Text Available Lithium users are offered routine renal monitoring but few studies have quantified the risk to renal health. The aim of this study was to assess the association between use of lithium carbonate and incidence of renal failure in patients with bipolar disorder.This was a retrospective cohort study using the General Practice Research Database (GPRD and a nested validation study of lithium exposure and renal failure. A cohort of 6360 participants aged over 18 years had a first recorded diagnosis of bipolar disorder between January 1, 1990 and December 31, 2007. Data were examined from electronic primary care records from 418 general practices across the UK. The primary outcome was the hazard ratio for renal failure in participants exposed to lithium carbonate as compared with non-users of lithium, adjusting for age, gender, co-morbidities, and poly-pharmacy.Ever use of lithium was associated with a hazard ratio for renal failure of 2.5 (95% confidence interval 1.6 to 4.0 adjusted for known renal risk factors. Absolute risk was age dependent, with patients of 50 years or older at particular risk of renal failure: Number Needed to Harm (NNH was 44 (21 to 150.Lithium is associated with an increased risk of renal failure, particularly among the older age group. The absolute risk of renal failure associated with lithium use remains small.

    To determine the frequency of thrombotic complications and to identify factors associated with arteriovenous thrombosis in patients of chronic renal failure receiving renal replacement therapy. Of the 3000 patients evaluated, 61 End Stage Renal Disease (ESRD) patients on regular dialysis, having recent renal transplant, were selected for the study after informed consent. These patients had arteriovenous thrombosis with temporary central lines thrombosis and vascular access problems. Cases of congenital or acquired thrombotic disorders, e.g. with malignancy, DIC, liver disease, systemic lupus erythematosus or other immunologic diseases, pregnancy or women using oral contraceptives, were excluded. Similarly, patients taking any type of anticoagulant therapy during the preceding one week were not included in the study. Findings were recorded in a structured questionnaire. Laboratory analysis was done after clinical and radiological evaluation. Thrombophilia screening included antithrombin, protein C, protein S deficiencies and lupus anticoagulant. Forty-seven out of 61 patients selected were positive for thrombophilia screening with protein C deficiency in 26.2%, protein S deficiency in 16.3%, antithrombin in 5%, lupus anticoagulant in 13.1% and combined deficiency was observed in 16.3%. Of the 3000 patients, 61 with frequency of 2% were found to be deficient in one or had combined deficiency of these. Thus, the study of ESRD patients presenting with arteriovenous thromboembolism emphasizes the need to reconsider the perception that this clinical entity is rare and requires further studies.

    Full Text Available Cerebral arteriovenous fistula (AVF is a vascular malformation that is rare in the pediatric population. Older children with cerebral AVF tend to present with neurologic problems related to intracranial venous hypertension or intracranial hemorrhage. Cardiac and pulmonary complications following acute neurologic injury such as subarachnoid hemorrhage are common in adults, but are rarely reported in children. However, complications have been reported in cases of enterovirus 71 rhombencephalitis in infants and children and can cause high morbidity and mortality. Here, we report a 14-year-old boy who presented with cardiac failure associated with pulmonary edema following cerebral hemorrhagic stroke due to AVF. After aggressive investigation and management, we intervened before significant hypoxia and hypotension developed, potentially reducing the risk of long-term adverse neurologic consequences in this patient.

    Acute kidney injury (AKI) is an important clinical issue, especially in the setting of critical care. It has been shown in multiple studies to be a key independent risk factor for mortality, even after adjustment for demographics and severity of illness. There is wide agreement that a generally applicable classification system is required for AKI which helps to standardize estimation of severity of renal disfunction and to predict outcome associated with this condition. That's how RIFLE (Risk-Injury-Failure-Loss-End-stage renal disease), and AKIN (Acute Kidney Injury Network) classifications for AKI were found in 2004 and 2007, respectively. In the clinical setting of heart failure, a positive fluid balance (often expressed in the literature as weight gain) is used by disease management programs as a marker of heart failure decompensation. Oliguria is defined as urine output less than 0,3 ml/kg/h for at least 24 h. Since any delay in treatment can lead to a dangerous progression of the AKI, early recognition of oliguria appears to be crucial. Critically ill patients with oliguric AKI are at increased risk for fluid imbalance due to widespread systemic inflammation, reduced plasma oncotic pressure and increased capillary leak. These patients are particulary at risk of fluid overload and therefore restrictive strategy of fluid administration should be used. Objective, rapid and accurate volume assessment is important in undiagnosed patients presenting with critical illness, as errors may result in interventions with fatal outcomes. The historical tools such as physical exam, and chest radiography suffer from significant limitations. As gold standard, radioisolopic measurement of volume is impractical in the acute care enviroment. Newer technologies offer the promise of both rapid and accurate bedside estimation of volume status with the potential to improve clinical outcomes. Blood assessment with bioimpendance vector analysis, and bedside ultrasound seem to be

    Although renal dysfunction is a known complication of acute liver failure (ALF), its frequency, severity, and impact among patients with ALF on the US liver transplant list are not well defined. Organ Procurement and Transplantation data for ALF patients listed as status 1/1A from 2002 to 2012 were analyzed. The frequency and severity of renal dysfunction at the time of listing [the latter was categorized in 5 stages using estimated GFR (eGFR) according to Chronic Kidney Disease Epidemiology Collaboration creatinine 2009 equation] were determined and the association between renal dysfunction and waiting list mortality was assessed using Cox proportional hazard regression analysis. There were a total of 2280 adult patients with ALF, including 56 % with renal dysfunction (defined as eGFR renal dysfunction was among those with ALF caused by hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome, fatty liver disease of pregnancy, heat stroke/hyperthermia, hepatitis A virus, and drug-induced liver injury due to acetaminophen APAP, phenytoin, trimethoprim-sulfamethoxazole, and macrolides. Despite the fact that 69 % (468/674) of patients with APAP-induced ALF listed as status 1/1A had renal dysfunction, only 0.9 % underwent simultaneous liver-kidney transplantation. Six-week survival probabilities in patients with ALF on the liver transplant waiting list were 71, 59, 56, 59, and 42 % with renal dysfunction stages of 1, 2, 3, 4, and 5, respectively. Multivariate analysis showed that after controlling for age, etiology of ALF, INR, total bilirubin, and region, the relative risk of death increased progressively as eGFR declined (P renal dysfunction was common (overall prevalence of 56 %). Most importantly, severe renal dysfunction was associated with significantly increased mortality.

    Renal sonography is a routine step in the evaluation of new onset renal failure. When renal masses are discovered in this setting, functional imaging may be critical. We report a case of bilateral renal masses in a girl with urinary tract infection and renal insufficiency found to have vesicoureteral reflux. Renal scintigraphy revealed these masses to be the only remaining functional renal tissue, preventing potentially harmful resection. (orig.)

    The aim of this study was to investigate the factors affecting recovery and durability of dialysis-independent renal function following commencement of peritoneal dialysis (PD). Retrospective, observational cohort study of the Australian and New Zealand PD patient population. Australia and New Zealand Dialysis and Transplant (ANZDATA) Registry. The study reviewed all patients in Australia and New Zealand who commenced PD for treatment of end-stage renal failure between 15 May 1963 and 31 December 2004. The primary outcomes examined were recovery of dialysis-independent renal function and time from PD commencement to recovery of renal function. A secondary outcome measure was time to renal death (patient death or recommencement of renal replacement therapy) following recovery of dialysis-independent renal function. 24663 patients commenced PD during the study period. Of these, 253 (1%) recovered dialysis-independent renal function. An increased likelihood of recovery was predicted by autoimmune renal disease, hemolytic-uremic syndrome, paraproteinemia, cortical necrosis, renovascular disease, and treatment in New Zealand. A reduced likelihood of recovery was associated with polycystic kidney disease and indigenous race. Analysis of a contemporary subset of 14743 patients in whom complete data were available for body mass index, smoking, and comorbidities yielded comparable results, except that increasing age was additionally associated with a decreased likelihood of recovery. Of the 253 patients who recovered renal function, 151 (60%) recommenced renal replacement therapy and 49 (19%) died within a median period of 226 days (interquartile range 110-581 days). The only significant predictors of continued renal survival after renal recovery were autoimmune renal disease and cortical necrosis. Recovery of renal function in patients treated with PD is rare and determined mainly by renal disease type and race. In the majority of cases, recovery is short term. The

    Heart failure and kidney disease share common pathophysiological pathways which can lead to mutual dysfunction, known as cardiorenal syndrome. In heart failure patients, renal impairment is related to hemodynamic and non-hemodynamic factors. Both decreased renal blood flow and renal venous congestion due to heart failure could lead to impaired renal function. Kidney disease and worsening renal function are independently associated with poor prognosis in heart failure patients, both in acute and chronic clinical settings. The aim of this review is to assess the role of renal imaging modalities in the evaluation and management of heart failure patients. Renal imaging techniques could complete laboratory data, as estimated glomerular filtration rate, exploring different pathophysiological factors involved in kidney disease and adding valuable information about renal structure and function. In particular, Doppler examination of arterial and venous hemodynamics is a feasible and non invasive technique, which has proven to be a reliable method for prognostic stratification in patients with cardiorenal syndrome. The renal resistance index, a measure related to renal hemodynamics, can be calculated from the Doppler evaluation of arterial flow. Moreover, the analysis of Doppler venous flow patterns can integrate information from the arterial study and evaluate renal congestion. Other imaging modalities are promising, but still confined to research purposes.

    The widespread prevalence of bone disease in chronic renal failure both prior to and during hemodialysis is an important aspect of uremia. Loss of bone mineral of the skeleton in renal disease can be measured directly by total-body neutron activation analysis (TBNAA). The absorptiometric technique, using monochromatic photons from 125 I, applied to the appendicular skeleton (radius) also reflects the loss of bone mineral content (BMC) in renal disease. The results of these two techniques were compared in 25 patients with renal insufficiency, 53 with end stage renal failure on dialysis, and 24 normal control subjects. (U.S.)

    Full Text Available Abstract Background Hornet stings are generally associated with local and occasionally anaphylactic reactions. Rarely systemic complications like acute renal failure can occur following multiple stings. Renal failure is usually due to development of acute tubular necrosis as a result of intravascular haemolysis, rhabdomyolysis or shock. Rarely it can be following development of acute tubulo-interstitial nephritis. Case presentation We describe a young male, who was stung on face, head, shoulders and upper limbs by multiple hornets (Vespa orientalis. He developed acute renal failure as a result of acute tubulo-interstitial nephritis and responded to steroids. Conclusion Rare causes of acute renal failure like tubulo-interstitial nephritis should be considered in a patient with persistent oliguria and azotemia following multiple hornet stings. Renal biopsy should be undertaken early, as institution of steroid therapy may help in recovery of renal function

    Septic shock is a rare, potentially life-threatening complication of bacterial dysentery. The clinical presentation of septic shock includes hypotension, bleeding, hypoxia, acidosis, and jaundice. Historically gram-negative organisms were the most frequent cause of nosocomial bloodstream infections. However isolation of gram-positive organisms has become increasingly frequent with Staphylococcus species accounting for over one half of all nosocomial bloodstream pathogens. Bacterial dysentery is an acute diarrheal illness characterized by abdominal cramping, fever, and the production of mucoid, bloody stools. Laboratory findings include positive stool culture and increased leukocytes in direct fecal exam. Chemistry and hematology values may be abnormal. The disease is usually self-limiting but administration of antibiotics and rehydration therapy may be warranted in severe cases. This case study describes a 53 year old male who presented with diarrhea and diabetic acidosis and subsequently developed respiratory distress and renal failure due to shigellosis. Discussion of disease pathogenesis and treatment are provided.

    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 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.

    This study deals with the determination of thyroid related hormones (T4,T3 and TSH) levels in sudanese patients with end-stage renal disease (ESRD) and under haemodialysis to determine the best means of treatment. This is the first time in Sudan to investigate thyroid related hormones on patients with chronic renal failure and was done on 61 patients and 60 symptoms-free subjects as controls. Radioimmunoassay (RIA) technique is used for the determination of serum total T4 and T3,whereas, TSH was determination using immunoradiometric assay (IRMA). T-test calculation revealed that the mean concentrations of total T4 and T3 of the patients were much lower than that of the normal subjects (p 0.05).These results revealed that, serum total T4 levels tent to decline after long term treatment with haemodialysis. Serum total T3 level fluctuate in lower margin of the normal range in haemodialyzed patients. As serum total thyroxine (T4) tends to decline in haemodialyzed patients, the use of thyroxine replacement therapy is highly recommended. (Author)

    Full Text Available In this retrospective study, records of all patients aged one month to 12 years who presented with acute renal failure (ARF between May 2005 and August 2010 were retrieved. Clinical details, biochemistry, need for renal replacement therapy (RRT, cause of ARF and outcome at discharge were recorded. During this period, 230 children presented with ARF; their median age at presentation was 30 months (range: five-144 months; 120 (52.2% were males. The causes of ARF were acute tubular necrosis (ATN in 121 (52.6%, glomerular disorders in 5.7%, structural anomalies of the urinary tract in 9.6% and hemolytic uremic syndrome in 27 (11.7%. The mean duration of hospital stay was 17.8 ± 7.6 days. RRT was required for 54 patients (23.6%; peritoneal dialysis in 49 and hemodialysis in five patients. Complete recovery was noted in 99 study patients (43.2% and sequelae remained in 84 patients (36.7%. Forty-six patients (20.1% with ARF died. ATN secondary to septicemia was the most common cause of ARF in our study.

    A retrospective review of 246 patients with established acute renal failure (ARF) needing dialysis from 1990-1994 is reported from Hospital Sultanah Aminah, Johor Bahru. Peritoneal dialysis was more commonly used than haemodialysis or haemofiltration. Patients on mechanical ventilation in Intensive Care Unit (ICU) who were hypercatabolic and fluid overloaded were treated with haemofiltration. Males outnumbered females by a ratio of 1.5:1. The majority were Malays (61.4%). Most patients were from the district of Johor Bahru, but 41.5% were from other districts in the Johor state. The mean age was 47.1 years (SD 18.2). The ARF was caused by acute tubular necrosis in 55.3%, post-renal obstruction in 22.8%, nephrotoxins in 5.7% and other causes in 16.2%. The proportions of patients referred from the medical, surgical and obstetric and gynaecology units were 50.8%, 45.5% and 3.7% respectively. The mortality rate was 48%. Patients with established ARF should be dialysed early as they tolerate uraemia poorly. Prevention is by prompt treatment of patients with sepsis, avoidance of hypovolaemia and nephrotoxic drugs.

    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 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.

    Acute aortic dissection (AAD) is a life-threatening condition associated with high morbidity and mortality. The most important recognized acquired cause that leads to dissection is chronic arterial hypertension. With respect to the anuria and renal failure, aortic dissection is not something that is always considered and is still not a very common presentation unless both renal arteries come off the false lumen of the dissection. However, when present, preoperative renal failure in patients w...

    Acute renal failure can be caused by calcineurin inhibitors (CNIs), due to arteriolopathy and altered tubular function. Within this context, we present the case of a 14-month-old liver transplant recipient who suffered an acute polyuric renal failure during a short episode of hypercaloric feeding. In our case, CNI-induced distal RTA led to nephrocalcinosis and therefore to secondary nephrogenic diabetes insipidus. The diet with high renal solute load consequently resulted in an acute polyuric...

    A retrospective study of 35 newborn with acute renal failure is presented. The main causes of renal failure were neonatal hypoxia by asfixia or hemorrhagic shock (eight), congenital malformations (two) and hypertonic dehydration (25). Mortality rate was 22% including two neonates with severe congenital malformations. Sepsis was considered as the main complicating factor and often as inducer of renal failure. It was present on 55% of cases and on 75% of the deceased newborn. Cerebral injury was frequent but a follow-up study is necessary to establish the rate of neurologic sequelae. Early diagnosis and treatment of renal failure will decrease complications with improvement in prognosis. Etiological analysis of neonatal renal failure shows the need of a better health education of people and also medical control of pregnancy and perinatal period.

    Full Text Available Objective: To study the effect of Shenkang injection combined with hemodialysis treatment on renal function, renal anemia and cytokine levels in patients with chronic renal failure. Methods: A total of 68 patients with chronic renal failure who received hemodialysis treatment in our hospital during between October 2013 and February 2016 were selected and randomly divided into two groups, the observation group received Shenkang injection treatment in the process of dialysis, and the control group only received conventional symptomatic and supportive treatment. 8 weeks after treatment, serum was collected to determine the levels of renal function indexes, nutritional status indexes, anemia indexes and cytokines, and urine was collected to determine renal function indexes. Results: β2-MG, UA, Cr, phosphorus, IL-17, IL-23, CTGF, TGF-β1, FGF-2 and FGF-23 levels in serum as well as NGAL, KIM-1 and RBP levels in urine of observation group were significantly lower than those of control group, and TP, Alb, PA, calcium, Hb, EPO, Fe, TRF and FER levels in serum were significantly higher than those of control group. Conclusion: Shenkang injection combined with hemodialysis treatment helps to improve renal function, nutritional status and renal anemia, and reduce the synthesis of inflammation and renal interstitial fibrosis-related cytokines in patients with chronic renal failure.

    The second most common cause of hospitalization due to adverse drug reactions in the UK is renal dysfunction due to diuretics, particularly in patients with heart failure, where diuretic therapy is a mainstay of treatment regimens. Therefore, the optimal frequency for monitoring renal function in these patients is an important consideration for preventing renal failure and hospitalization. This review looks at the current evidence for optimal monitoring practices of renal function in patients with heart failure according to national and international guidelines on the management of heart failure (AHA/NICE/ESC/SIGN). Current guidance of renal function monitoring is in large part based on expert opinion, with a lack of clinical studies that have specifically evaluated the optimal frequency of renal function monitoring in patients with heart failure. Furthermore, there is variability between guidelines, and recommendations are typically nonspecific. Safer prescribing of diuretics in combination with other antiheart failure treatments requires better evidence for frequency of renal function monitoring. We suggest developing more personalized monitoring rather than from the current medication‐based guidance. Such flexible clinical guidelines could be implemented using intelligent clinical decision support systems. Personalized renal function monitoring would be more effective in preventing renal decline, rather than reacting to it. PMID:28901643

    The aim of the study was to evaluate the causes, prevalence, and grades of chronic renal failure in Lithuanian children and to assess its influence on children's growth. The study was performed in Vilnius University Children's Hospital and Clinic of Children's Diseases, Kaunas University of Medicine. By March 31, 2006, 65 children with chronic renal failure had been registered. The prevalence was 88.3 cases per million children. The mean age was 10.8+/-4.9 years. The leading causes of chronic renal failure were congenital diseases (37%) and obstruction with interstitial nephritis (33.8%). At presentation, 23 (35.40%) children had mild, 17 (26.15%) had moderate, 9 (23.85%) had severe renal failure, and 16 (24.6%) had end-stage renal disease. Fourteen (21.54%) children were below the third percentile in height for their age. Growth failure was observed in one (4.35%) child with Grade 1 renal failure. The deterioration of renal function had a significant influence on growth impairment, and 13 (30.95%) children with glomerular filtration rate of less than 60 mL/min/1.73 m2 and 7 (43.75%) with end-stage renal disease had a height below the third percentile. Growth retardation as one of the symptoms of impairment of children's physical development depends on the severity of renal function.

    Glomerular filtration rate and/or creatinine are not accurate methods for renal failure prediction. This study tested homocysteine (Hcy) as a predictive and prognostic marker for end stage renal disease (ESRD). In total, 176 subjects were recruited and divided into: healthy normal group (108 subjects); mild-to-moderate impaired renal function group (21 patients); severe impaired renal function group (7 patients); and chronic renal failure group (40 patients) who were on regular hemodialysis. Blood samples were collected, and serum was separated for analysis of total Hcy, creatinine, high sensitive C-reactive protein (CRP), serum albumin, and calcium. Data showed that Hcy level was significantly increased from normal-to-mild impairment then significantly decreases from mild impairment until the patient reaches severe impairment while showing significant elevation in the last stage of chronic renal disease. Creatinine level was increased in all stages of kidney impairment in comparison with control. CRP level was showing significant elevation in the last stage. A significant decrease in both albumin and calcium was occurred in all stages of renal impairment. We conclude Hcy in combination with CRP, creatinine, albumin, and calcium can be used as a prognostic marker for ESRD and an early diagnostic marker for the risk of renal failure.

    Progressive decline in renal function has been well described in patients with Type 2 diabetes mellitus, but few studies have assessed the risk of acute renal failure in a large population of patients with Type 2 diabetes. This study quantified the risk of acute renal failure associated with Type 2 diabetes in the General Practice Research Database from the UK. Patients with Type 2 diabetes (n = 119,966) and patients without diabetes (n = 1,794,516) were identified in the General Practice Research Database. Patients with end-stage renal disease were excluded. Crude incidence and multivariate-adjusted hazard ratios of acute renal failure were estimated for patients with diabetes relative to those without diabetes. Cox regression models were adjusted for a variety of comorbidities. Increase of acute renal failure risk resulting from additive effects of specific co-morbidities with Type 2 diabetes was also assessed. Between 2003 and 2007, acute renal failure incidence was 198 per 100,000 person-years in patients with Type 2 diabetes compared with 27 per 100,000 patients-years among patients without diabetes (crude hazard ratio 8.0, 95% CI 7.4-8.7). Risk of acute renal failure for patients with Type 2 diabetes remained significant, but was attenuated in multivariate analyses adjusting for various comorbidities (adjusted hazard ratio 2.5, 95% CI 2.2-2.7). Age and specific comorbidities (chronic kidney disease, hypertension and congestive heart failure) were also associated with increased risk of acute renal failure in Type 2 diabetes. Patients with Type 2 diabetes have increased risk for acute renal failure compared with patients without diabetes, even after adjustment for known risk factors, particularly in the elderly and those with other comorbidities such as chronic kidney disease, congestive heart failure and hypertension. © 2011 The Authors.

    Despite the significant morbidity associated with renal failure after lung transplantation (LTx), no predictive models currently exist. Accordingly, the purpose of this study was to develop a preoperative risk score based on recipient-, donor-, and transplant-specific characteristics to predict postoperative acute renal failure in candidates for transplantation. The United Network of Organ Sharing (UNOS) database was queried for adult patients (≥ 18 years of age) undergoing LTx between 2005 and 2012. The population was randomly divided into derivation (80%) and validation (20%) cohorts. The primary outcome of interest was new-onset renal failure. Variables predictive of acute renal failure (exploratory p value renal failure to construct the risk stratification score (RSS). During the study period, 10,963 patients underwent lung transplantation, and the incidence of renal failure was 5.5% (598 patients). Baseline recipient-, donor-, and transplant-related factors were similar between the cohorts. Eighteen covariates were included in the multivariable model, and 10 were assigned values based on their relative odds ratios (ORs). Scores were stratified into 3 groups, with an observed rate of acute renal failure of 3.1%, 5.3%, and 15.6% in the low-, moderate-, and high-risk groups, respectively. The incidence of renal failure was found to be significantly increased in the highest risk group (p renal failure highly correlated with actual rates observed in the population (r = 0.86). We introduce a novel and simple RSS that is highly predictive of renal failure after LTx. Copyright © 2015 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

    Full Text Available Background: The incidence of acute renal failure (ARF in the hospital setting is increasing. It portends excessive morbidity and mortality and a considerable burden on hospital resources. Extracorporeal therapies show promise in the management of patients with shock and ARF. It is said that the potential of such therapy goes beyond just providing renal support. The aim of our study was to analyze the clinical setting and outcomes of critically ill ARF patients managed with continuous renal replacement therapy (CRRT. Patients and Methods: Ours was a retrospective study of 50 patients treated between January 2004 and November 2005. These 50 patients were in clinical shock and had concomitant ARF. All of these patients underwent CVVHDF (continuous veno-venous hemodiafiltration in the intensive care unit. For the purpose of this study, shock was defined as systolic BP < 100 mm Hg in spite of administration of one or more inotropic agents. SOFA (Sequential Organ Failure Assessment score before initiation of dialysis support was recorded in all cases. CVVHDF was performed using the Diapact ® (Braun CRRT machine. The vascular access used was as follows: femoral in 32, internal jugular in 8, arteriovenous fistula (AVF in 4, and subclavian in 6 patients. We used 0.9% or 0.45% (half-normal saline as a prefilter replacement, with addition of 10% calcium gluconate, magnesium sulphate, sodium bicarbonate, and potassium chloride in separate units, while maintaining careful monitoring of electrolytes. Anticoagulation of the extracorporeal circuit was achieved with systemic heparin in 26 patients; frequent saline flushes were used in the other 24 patients. Results: Of the 50 patients studied, 29 were males and 21 females (1.4:1. The average age was 52.88 years (range: 20-75 years. Causes of ARF included sepsis in 24 (48%, hemodynamically mediated renal failure (HMRF in 18 (36%, and acute over chronic kidney disease in 8 (16% patients. The overall mortality was

    Nitroglycerin is commonly used as an antispasmodic for treating spasm of coronary artery bypass grafts. This study investigated whether the presence of renal failure affects reactivity to nitroglycerin in internal thoracic arteries obtained from patients undergoing coronary bypass surgery. The patients were divided into three groups according to estimated glomerular filtration rate (eGFR, mL/min/1.73 m 2 ): without renal failure (60 ≤ eGFR, n = 13), with moderate renal failure (30 ≤ eGFR renal failure (eGFR renal failure than in those without renal failure. In addition, there was a negative correlation between eGFR and the relaxant efficacy of nitroglycerin (P = 0.016). On the other hand, relaxant responses to BAY 60-2770 (which enhances cGMP generation as with nitroglycerin) were similar among three grades of renal function. An inverse relationship of eGFR to the relaxant efficacy of BAY 60-2770 was not observed, either (P = 0.314). These findings suggest that severe renal failure specifically potentiates nitroglycerin-induced relaxation in internal thoracic artery grafts.

    This study investigated the effect of renal bradykinin B1 and B2 receptor blockade on the high- and low-pressure baroreceptor reflex regulation of renal sympathetic nerve activity (RSNA) in rats with cisplatin-induced renal failure. Cisplatin (5 mg/kg) or saline was given intraperitoneally 4 days prior to study. Following chloralose/urethane anaesthesia, rats were prepared for measurement of mean arterial pressure (MAP), heart rate and RSNA and received intrarenal infusions of either Lys-[des-Arg 9 , Leu 8 ]-bradykinin (LBK), a bradykinin B1 receptor blocker, or bradyzide (BZ), a bradykinin B2 receptor blocker. RSNA baroreflex gain curves and renal sympatho-inhibitory responses to volume expansion (VE) were obtained. In the control and renal failure groups, basal MAP (89 ± 3 vs. 80 ± 8 mmHg) and RSNA (2.0 ± 0.3 vs. 1.7 ± 0.6 μV.s) were similar but HR was lower in the latter group (331 ± 8 vs. 396 ± 9 beats/min). The baroreflex gain for RSNA in the renal failure rats was 39% (P renal failure rats. Intrarenal LBK infusion in the renal failure rats normalized the VE induced renal sympatho-inhibition whereas BZ only partially restored the response. These findings suggest that pro-inflammatory bradykinin acting at different receptors within the kidney generates afferent neural signals which impact differentially within the central nervous system on high- and low-pressure regulation of RSNA. © 2016 Scandinavian Physiological Society.

  18. Tacrolimus Aggravated Tube Feeding Syndrome with Acute Renal Failure in a Pediatric Liver Transplant Recipient

    2017-01-01

    Full Text Available Acute renal failure can be caused by calcineurin inhibitors (CNIs, due to arteriolopathy and altered tubular function. Within this context, we present the case of a 14-month-old liver transplant recipient who suffered an acute polyuric renal failure during a short episode of hypercaloric feeding. In our case, CNI-induced distal RTA led to nephrocalcinosis and therefore to secondary nephrogenic diabetes insipidus. The diet with high renal solute load consequently resulted in an acute polyuric renal failure with severe hypernatremic dehydration. In conclusion, a hypercaloric diet in children with potentially impaired renal function due to therapy with CNIs requires precise calculation of the potential renal solute load and the associated fluid requirements.

    Full Text Available Partial EN (enteral nutrition should always be aimed for in patients with renal failure that require nutritional support. Nevertheless PN (parenteral nutrition may be necessary in renal failure in patient groups with acute or chronic renal failure (ARF or CRF and additional acute diseases but without extracorporeal renal replacement therapy, or in patients with ARF or CRF with additional acute diseases on extracorporeal renal replacement therapy, haemodialysis therapy (HD, peritoneal dialysis (PD or continuous renal replacement therapy (CRRT, or in patients on HD therapy with intradialytic PN. Patients with renal failure who show marked metabolic derangements and changes in nutritional requirements require the use of specifically adapted nutrient solutions. The substrate requirements of acutely ill, non-hypercatabolic patients with CRF correspond to those of patients with ARF who are not receiving any renal replacement patients therapy (utilisation of the administered nutrients has to be monitored carefully. In ARF patients and acutely ill CRF patients on renal replacement therapy, substrate requirements depend on disease severity, type and extent/frequency of extracorporeal renal replacement therapy, nutritional status, underlying disease and complications occurring during the course of the disease. Patients under HD have a higher risk of developing malnutrition. Intradialytic PN (IDPN should be used if causes of malnutrition cannot be eliminated and other interventions fail. IDPN should only be carried out when modifiable causes of malnutrition are excluded and enhanced oral (like i.e. additional energy drinks or enteral supply is unsuccessful or cannot be carried out.

    Periodontitis, a chronic infectious disease, affects most of the population at one time or the other and its expression is a combination of hosts, microbial agents, and environmental factors. Extensive literature exists for the relationship between periodontal disease and diabetes mellitus, cardiovascular diseases, and adverse pregnancy outcomes. Only a few studies performed in a limited number of patients have reported peri-odontal health status in chronic renal failure patients. Hence, the aim of the present study is to assess and compare the periodontal status of patients with chronic renal failure undergoing dialysis, predialysis with systemically healthy individuals. A total of 90 patients were divided into three groups. Group I: 30 renal dialysis patients. Group II: 30 predialysis patients. Control group comprised 30 systemically healthy patients who formed group III. Periodontal examination was carried out using oral hygiene index-simplified (OHI-S), plaque index (PI), gingival index (GI), probing depth, and clinical attachment loss. The results of the study showed that the periodontal status of patients with chronic renal failure undergoing dialysis (dialysis group) and patients with chronic renal failure not undergoing renal dialysis (predialysis) when compared with systemically healthy subjects showed significantly higher mean scores of OHI-S, PI, and clinical attachment loss. Thus, patients with chronic renal failure showed poor oral hygiene and higher prevalence of periodontal disease. The dental community's awareness of implications of poor health within chronic renal failure patients should be elevated.

    The aim of this study was to identify predictors of 'intrauterine fetal renal failure' in fetuses with severe congenital lower urinary tract obstruction (LUTO). We undertook a retrospective study of 31 consecutive fetuses with a diagnosis of LUTO in a tertiary Fetal Center between April 2013 and April 2015. Predictors of 'intrauterine fetal renal failure' were evaluated in those infants with severe LUTO who had either a primary composite outcome measure of neonatal death in the first 24 h of life due to severe pulmonary hypoplasia or a need for renal replacement therapy within 7 days of life. The following variables were analyzed: fetal bladder re-expansion 48 h after vesicocentesis, fetal renal ultrasound characteristics, fetal urinary indices, and amniotic fluid volume. Of the 31 fetuses included in the study, eight met the criteria for 'intrauterine fetal renal failure'. All of the latter had composite poor postnatal outcomes based on death within 24 h of life (n = 6) or need for dialysis within 1 week of life (n = 2). The percentage of fetal bladder refilling after vesicocentesis at time of initial evaluation was the only predictor of 'intrauterine fetal renal failure' (cut-off renal failure' in fetuses with the most severe forms of LUTO. Fetal bladder refilling can be used to reliably predict 'intrauterine fetal renal failure', which is associated with severe pulmonary hypoplasia or the need for dialysis within a few days of life.

    Calcific aortic valve disease (CAVD) is currently the most common heart valve disease worldwide and is known to be an active process. Both renal failure and dyslipidaemia are considered to be promoting factors for the development of valvular calcifications. The aim of this study is to prospectively evaluate the respective contribution and interaction of renal failure and dyslipidaemia on CAVD in a rat model, using echocardiography and compared with histology. Sixty-eight male Wistar rats were prospectively divided in eight groups, each fed a different diet to induce renal failure alone and combined with hyperlipidaemia or hypercholesterolemia. CAVD was detected and quantified by calibrated integrated backscatter of ultrasound (cIB) and compared with the histological calcium score. The study follow-up was 20 weeks. At the end of the study, the cIB value and the calcium score of the aortic valve were significantly increased in the group with isolated renal failure but not with dyslipidaemia. The combination of renal failure with high cholesterol or high-fat diet did not significantly increase calcifications further. Renal failure alone does induce aortic valve calcifications in a rat model of CAVD, whereas dyslipidaemia alone does not. The combination of renal failure with dyslipidaemia does not increase calcification further. These findings suggest that a combination of atherosclerotic and calcifying factors is not required to induce aortic valve calcifications in this model.

    Smoking is known to suppress the immune system. It is also known that chronic renal failure affects the immune system. However, the number of studies investigating the effects of chronic renal failure and smoking together is limited. In our study, we examined whether smoking affects the diminished response of the immune system in patients with chronic renal failure. We compared peripheral blood lymphocyte subsets in smoking and nonsmoking patients with chronic renal failure. We also used the Fagerström Test for Nicotine Dependence to evaluate its correlation with the lymphocyte subset count in patients who are current smokers. Our study included 126 patients with chronic renal failure. According to their smoking habits, patients were divided into 2 groups: smokers and nonsmokers. The average age of patients who were smokers was 53.2 ± 1.5 years, with average age of nonsmokers being 59.2 ± 2.2 years. The average duration of smoking in smokers was 30.7 ± 2.7 packyears. We found that the percentage of cluster of differentiation 16-56 cells (natural killer cells) and lymphocyte percentage were significantly lower among smokers in our study (P renal failure, similar to that shown in healthy smokers. According to our findings, patients with chronic renal failure, where infection is the primary reason for mortality and morbidity, must be questioned for smoking and referred to smoking cessation clinics. Because of its immunosuppressive effects, smoking behaviors must be solved preoperatively in transplant candidates.

    Chronic kidney disease is associated with an increased risk of cardiovascular events. However, the impact of chronic kidney disease on cerebrovascular disease is less well understood. We hypothesized that renal function severity would be predictive of stroke risk, independent of other vascular risk factors. The study population included 3939 subjects enrolled in the Chronic Renal Insufficiency Cohort (CRIC) study, a prospective observational cohort. Stroke events were reported by participants and adjudicated by 2 vascular neurologists. Cox proportional hazard models were used to compare measures of baseline renal function with stroke events. Multivariable analysis was performed to adjust for key covariates. In 3939 subjects, 143 new stroke events (0.62 events per 100 person-years) occurred over a mean follow-up of 6.4 years. Stroke risk was increased in subjects who had worse baseline measurements of renal function (estimated glomerular filtration rate and total proteinuria or albuminuria). When adjusted for variables known to influence stroke risk, total proteinuria or albuminuria, but not estimated glomerular filtration rate, were associated with an increased risk of stroke. Treatment with blockers of the renin-angiotensin system did not decrease stroke risk in individuals with albuminuria. Proteinuria and albuminuria are better predictors of stroke risk in patients with chronic kidney disease than estimated glomerular filtration rate. The impact of therapies targeting proteinuria/albuminuria in individuals with chronic kidney disease on stroke prevention warrants further investigation. © 2015 American Heart Association, Inc.

    Chronic kidney disease (CKD) from diabetic nephropathy is characterized by progressive loss of renal function. The renal decline has been viewed as a linear fall, presumably dependent on metabolic, hemodynamic and dietary stresses. However, renal injury in diabetic nephropathy can be rapidly aggravated by unpredictable external and internal factors, a state of affairs inconsistent with a linear loss of function. Acute renal injury and subsequent inflammation are potential factors, and we investigated their presence in renal biopsies from patients with nephropathy. In a protocol approved by the Indiana University School of Medicine Institutional Review Board, renal biopsy specimens, estimated GFR, proteinuria and renal survival were examined in patients with diabetic nephropathy. Prominent clusters of inflammatory cells, particularly macrophages, were detected in the renal biopsy specimens. CKD progressed rapidly but not linearly, in that CKD was characterized by a succession of seemingly random episodes of self-limited acute renal failure. Episodes of acute kidney injury were associated with progression to end-stage renal disease. We propose that diabetic nephropathy is complicated by unpredictable and possibly random episodes of usually self-limited acute renal failure, and by subsequent renal inflammation, which appear to accelerate progression and eventual kidney loss.

    Inotropic drugs are part of the treatment of heart failure; however, inotropic treatment has been largely debated due to the increased incidence of adverse effects and increased mortality. Recently levosimendan, an inotropic positive agent, has been proved to be effective in acute heart failure, reducing the mortality and improving cardiac and renal performance. We report the case of a 75-year-old woman with history of heart and renal failure and hip fracture. Levosimendan was used in preoperative preparation as an adjuvant therapy, to improve cardiac and renal function and to allow surgery. Copyright © 2014 Sociedade Brasileira de Anestesiologia.

    2018-03-01

    Full Text Available A 58-year-old male presented with native joint septic arthritis of the hip and osteomyelitis. After treatment with an articulating antibiotic spacer, he developed acute renal failure requiring dialysis. He continued to have elevated serum tobramycin levels exclusively from the antibiotic spacer elution as no intravenous tobramycin was used. Subsequent explantation was required to correct his renal failure. Although renal failure after antibiotic impregnated cement placement is rare, the risk of this potential complication should be considered preoperatively and in the postoperative management of these patients.

    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.

    Postischemic acute renal failure (ARF) induced by cardiac surgery is commonly prolonged and may be irreversible. To examine whether persistence of postischemic, tubular cell injury accounts for delayed recovery from ARF, we studied 10 patients developing protracted (36 +/- 4 d) ARF after cardiac surgery. The differential clearance and excretion dynamics of probe solutes of graded size were determined. Inulin clearance was depressed (5.0 +/- 1.7 ml/min), while the fractional urinary clearance of dextrans (radii 17-30 A) were elevated above unity. Employing a model of conservation of mass, we calculated that 44% of filtered inulin was lost via transtubular backleak. The clearance and fractional backleak of technetium-labeled DTPA ([/sup 99m/Tc]DTPA, radius = 4 A) were identical to those of inulin (radius 15 A). The time at which inulin or DTPA excretion reached a maximum after an intravenous bolus injection was markedly delayed when compared with control subjects with ARF of brief duration, 102 vs. 11 min. Applying a three-compartment model of inulin/DTPA kinetics (which takes backleak into account) revealed the residence time of intravenously administered inulin/DTPA in the compartment occupied by tubular fluid and urine to be markedly prolonged, 20 vs. 6 min in controls, suggesting reduced velocity of tubular fluid flow

    Continuous arteriovenous hemofiltration (CAVH) has become an accepted therapy for patients with acute renal failure. A major technical concern with CAVH is clotting of the hemofilter, resulting from blood-material interactions. This study compares the thromboresistance and performance characteristics of a Duraflo II heparin treated CAVH circuit with those of an untreated control circuit. The circuit consisted of a polysulfone hemofilter, tubing sets, and catheters. The heparin treatment did not change the mass transfer properties of the hemofilter. The thromboresistance of the heparin treated circuit was compared directly with that of an untreated circuit in a heparinless sheep model using bilateral circuits. The heparin treatment significantly enhanced the blood compatibility of the circuit, as indicated by the reduction in thrombus formation, prolonged work life, and superior performance in heparinless sheep. There was minimal heparin leaching from the hemo-filter. A heparin treated circuit may improve the safety and effectiveness of the CAVH procedure, and offers potential for a systemic heparin protocol to be modified for patients with bleeding disorders.

    Inflammation and oxidative stress are involved in the process of chronic renal failure (CRF). CRF patients show indication of sleep disturbances, and the melatonin rhythm, which modulates sleep, is abnormal in these patients; however, it is still unclear whether inflammation could be related to the blockage of melatonin production and sleep disturbances in this population. The aim of this study was to characterize and correlate sleep, the melatonin rhythm, and the levels of the inflammatory cytokines tumor necrosis factor (TNF) and interleukin (IL)-6 in patients with CRF and controls. Sleep was evaluated by the "Sleep Quality Index Pittsburgh" (PSQI) questionnaire, and melatonin and cytokine contents in saliva and blood samples, respectively, were analyzed by ELISA. The CRF group scored higher on the global PSQI, which indicates a lower sleep quality and a higher prevalence of sleep disorders, than the control group. The CRF individuals also showed lower melatonin content than the control groups, both during the day and at night, and lacked rhythmicity in melatonin production. The CRF group also showed higher contents of TNF and IL-6 than the control group and a negative correlation between TNF and melatonin content. These results suggest that the sleep disorders observed in the CRF group were probably related to the low production of melatonin observed in this population. The high level of TNF, as previously demonstrated in other pathologies, is probably involved in this blockage of melatonin production in CRF.

    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. Copyright © 2015 Elsevier GmbH. All rights reserved.

    Twenty mechanically ventilated patients with acute renal failure were studied on 31 occasions to determine their energy expenditure (EE) during a 2 h period before a hemodialysis. Oxygen consumption and CO2 elimination were measured continuously with a mass spectrometer system. EE (1660 +/- 48 kcal day-1) was close to the total caloric intake (1682 +/- 83 kcal day-1) and represented 1.19 +/- 0.03 times the predicted resting energy expenditure (PREE) with large inter-individual variations (0.7-1.7 PREE). EE/PREE was higher when sepsis was present (1.31 +/- 0.03 versus 1.14 +/- 0.02; p less than 0.05). Glucose oxidation rate (4.35 mg kg-1 min-1) exceeded glucose intake (2.6 mg kg-1 min-1). Respiratory quotient was 1.02 +/- 0.01. Nitrogen loss was 17.3 +/- 1.7 g day-1 and nitrogen balance -11.9 +/- 1.9 g day-1. In conclusion, EE values were scattered but never exceeded 1.7 times the PREE. Sepsis increased EE. With a nutritional support covering EE, nitrogen balance remained markedly negative and a preferential utilisation of glucose and lipogenesis occurred.

Randomized, placebo-controlled, prospective study. University cardiology center. Two hundred fifty-four consecutive patients with chronic renal insufficiency (estimated creatinine clearance acute renal failure (> 25% increase in serum creatinine from baseline) and the in-hospital clinical course were evaluated. Acute renal failure occurred in 46% of patients and was associated with increased in-hospital mortality (7% vs. 0.7%; p = .024). It occurred in 52% of control patients and 40% of N-acetylcysteine-treated patients (p = .06). In-hospital mortality and need for renal replacement therapy were not affected by N-acetylcysteine, but a lower percentage of N-acetylcysteine-treated patients required mechanical ventilation prolonged for > 48 hrs (3% vs. 18%; p 4 days (13% vs. 33%; p acute renal failure in patients with renal insufficiency undergoing cardiac surgery.

    The aim of this study was to assess changes in organ function in acute renal failure patients during renal replacement therapy and relate them to outcome. Medical and nursing charts from 111 patients with acute renal failure who underwent renal replacement therapy (hemodialysis or hemofiltration) from July 2000 until July 2002 on a 31-bed medicosurgical intensive care unit (ICU) at a university hospital in Belgium and in whom the Sequential Organ Failure Assessment (SOFA) score was calculated daily before the start of therapy until the seventh day, or the end of therapy, were analyzed. Changes in SOFA score over time (Delta SOFA) were calculated. Of 111 patients, 63 (57%) died in the ICU. Nonsurvivors were older (68 [52-76] vs 59 [48-70] years, P = .017) and had initially higher respiratory, cardiovascular, and total SOFA scores compared with survivors. A greater Delta renal SOFA at 24 hours was associated univariantly with a higher risk of ICU mortality (odds ratio, 1.7; 95% confidence interval, 1.2-2.6; P = .013). In a multivariate analysis with ICU outcome as the dependent variable, only age, cardiovascular SOFA score on admission, and the change in total SOFA score over the first 24 hours were independently associated with a greater risk of death. Assessment of these factors in the first 24 hours of renal replacement therapy could help identify patients at higher risk of mortality early during their ICU admission.

    Heart failure syndrome results from compensatory mechanisms that operate to restore - back to normal - the systemic perfusion pressure. Sympathetic overactivity plays a pivotal role in heart failure; norepinephrine contributes to maintenance of the systemic blood pressure and increasing preload. Cardiac norepinephrine spillover increases in patients with heart failure; norepinephrine exerts direct toxicity on cardiac myocytes resulting in a decrease of synthetic activity and/or viability. Importantly, cardiac norepinephrine spillover is a powerful predictor of mortality in patients with moderate to severe HF. This provided the rationale for trials that demonstrated survival benefit associated with the use of beta adrenergic blockers in heart failure with reduced ejection fraction. Nevertheless, the MOXCON trial demonstrated that rapid uptitration of moxonidine (inhibitor of central sympathetic outflow) in patients with heart failure was associated with excess mortality and morbidity, despite reduction of plasma norepinephrine. Interestingly, renal norepinephrine spillover was the only independent predictor of adverse outcome in patients with heart failure, in multivariable analysis. Recently, renal sympathetic denervation has emerged as a novel approach for control of blood pressure in patients with treatment-resistant hypertension. This article summarizes the available evidence for the effect of renal sympathetic denervation in the setting of heart failure. Key messages Experimental studies supported a beneficial effect of renal sympathetic denervation in heart failure with reduced ejection fraction. Clinical studies demonstrated improvement of symptoms, and left ventricular function. In heart failure and preserved ejection fraction, renal sympathetic denervation is associated with improvement of surrogate endpoints.

    A 26-year-old Japanese man without hypouricemia and with 3 previous episodes of seizures concurrent with acute kidney injury (AKI) was admitted due to an epileptic seizure, lower back pain and AKI. His creatinine kinase levels were slightly elevated. Patchy renal ischemia on contrast-enhanced computed tomography and persistent residual contrast medium was observed, consistent with acute renal failure with severe loin pain and patchy renal ischemia after anaerobic exercise (ALPE). Diffusion-weighted imaging (DWI) demonstrated signal changes in the corresponding area. ALPE should be considered a cause of AKI following seizures. We recommend DWI as an alternative diagnostic modality.

  19. The role of the renal afferent and efferent nerve fibers in heart failure

    Renal nerves contain afferent, sensory and efferent, sympathetic nerve fibers. In heart failure (HF) there is an increase in renal sympathetic nerve activity (RSNA), which can lead to renal vasoconstriction, increased renin release and sodium retention. These changes are thought to contribute to renal dysfunction, which is predictive of poor outcome in patients with HF. In contrast, the role of the renal afferent nerves remains largely unexplored in HF. This is somewhat surprising as there are multiple triggers in HF that have the potential to increase afferent nerve activity, including increased venous pressure and reduced kidney perfusion. Some of the few studies investigating renal afferents in HF have suggested that at least the sympatho-inhibitory reno-renal reflex is blunted. In experimentally induced HF, renal denervation, both surgical and catheter-based, has been associated with some improvements in renal and cardiac function. It remains unknown whether the effects are due to removal of the efferent renal nerve fibers or afferent renal nerve fibers, or a combination of both. Here, we review the effects of HF on renal efferent and afferent nerve function and critically assess the latest evidence supporting renal denervation as a potential treatment in HF. PMID:26483699

    Lewis, Helen; Arber, Sara

    2015-01-01

    Previous medical research has shown that children with end-stage renal failure experience delay or underachievement of key markers of transition to adulthood. This article analyses 35 qualitative interviews with end-stage renal failure patients, aged 20-30 years, first diagnosed at 0-19 years of age, to explore how far delayed or underachievement in education and employment is related to their age at onset of end-stage renal failure. This study shows how unpredictable failures of renal replacement therapies, comorbidities and/or side effects of treatment in the early life course often coincided with critical moments for education and employment. Entering school, college, work-related training or employment, and disclosing health status or educational underachievement to an employer, were particularly critical, and those who were ill before puberty became progressively more disadvantaged in terms of successful transition into full-time employment, compared with those first diagnosed after puberty. © The Author(s) 2014.

    Full Text Available Adult coeliac disease commonly presents without classical symptoms as chronic diarrhea and weight loss. We describe the case of a 31-year-old woman with persistent life-threatening hypokalemia, acute renal failure, and acute quadriplegia due to diarrhea that had continued for one month. Although there are cases of coeliac disease diagnosed with hypokalemic rhabdomyolysis in the literature, none of the cases developed acute renal failure. This is the first case in the literature diagnosed with acute renal failure due to hypokalemic rhabdomyolysis as a presentation of coeliac disease. In acute renal failure cases that present with hypokalemic rhabdomyolysis due to severe diarrhea, coeliac disease should be considered as a differential diagnosis despite the negative antigliadin IgA antibody.

  7. Renal handling of drugs in renal failure. I: Differential effects of uranyl nitrate- and glycerol-induced acute renal failure on renal excretion of TEAB and PAH in rats

    International Nuclear Information System (INIS)

    Lin, J.H.; Lin, T.H.

    1988-01-01

    Two etiologically different models of experimental acute renal failure were induced in rats by administration of either glycerol or uranyl nitrate. Both compounds caused a substantial decrease in the glomerular filtration rate (GFR) and the net tubular secretion of tetraethylammonium bromide (TEAB) and para-aminohippuric acid (PAH). The degree of renal impairment induced by uranyl nitrate and glycerol appeared to be dose related. Deprivation of drinking water 24 hr before the administration of glycerol potentiated the renal damage. In uranyl nitrate-induced renal failure, the decline of the net tubular secretion for TEAB and PAH was not proportional to the decrease in GFR; the secretion process deteriorated faster than the GFR. For example, when 0.5 mg/kg uranyl nitrate was administered, GFR fell to approximately 65% of normal, whereas the net tubular secretion was decreased to 30% of normal. These results suggest that the tubular transport was preferentially affected by uranyl nitrate. In contrast, in glycerol-induced renal failure, the decline of TEAB secretion fell in a parallel fashion with the GFR, suggesting that the glomeruli and the proximal tubules were equally damaged by glycerol. However, in this latter model, the decline of PAH secretion did not parallel the decrease in GFR, contradicting the proposal that glycerol affects equally the glomeruli and the proximal tubules. This discrepancy may be due to the selective competitive inhibition of PAH secretion by the accumulation of naturally occurring organic acids

    Full Text Available Background: Renal impairment is regularly seen in hospitalized stroke patients, affecting the outcome of patients, as well as causing difficulties in their management. A prospective cohort study was conducted to assess the trend of renal function in hospitalized ischemic and haemorrhagic stroke patients. The incidence of renal impairment in these subgroups, the contributing factors and the need for renal replacement in renal impaired patients was evaluated. Methods: Alternate day renal function testing was performed in hospitalized stroke patients. Estimated glomerular filtration rate (e-GFR was calculated and the trend of renal function in the two stroke subgroups (haemorrhagic and ischemic was assessed, with renal impairment defined as e-GFR < 60mL/ minute per 1.73m2. Results: Among 52 patients, 25 had haemorrhagic stroke (mean age 59.81 ± 14.67 and 27 had ischemic stroke (mean age 56.12 ± 13.08. The mean e-GFR (mL/minute per 1.732m2 at admission in the haemorrhagic stroke subgroup was 64.79 ± 25.85 compared to 86.04 ± 26.09 in the ischemic stroke subgroup (p=0.005. Sixteen out of 25 (64% patients in the haemorrhagic stroke subgroup and 9 out of 27 (33.3% patients in the ischemic subgroup developed renal impairment (p=0.27. The location of the bleed (p=0.8, volume of hematoma (p=0.966 and surgical intervention (p=0.4 did not predispose the patients to renal impairment. One out of 16 patients with haemorrhagic stroke (who eventually died, and 2 out of 9 patients with ischemic stroke required renal replacement. Conclusion: Renal impairment is commonly seen in stroke patients, more so in patients who suffered haemorrhagic strokes.  The impairment, however, is transient and rarely requires renal replacement therapy.

    Hypertension is both the cause and consequence of chronic renal failure (CRF). The prevalence of CRF, which itself is a cardiovascular risk factor, is not well known in France. To estimate the prevalence of renal dysfunction among hypertensive patients who were seen by general practitioners (GP); to assess the drug management of hypertension in these patients according to their renal status. A transversal observational study among patients of both genders aged 18 or more, with arterial blood pressure greater than 130/80 mmHg (i.e., over CRF-recommended blood pressure) or under antihypertensive drugs who were recruited in France by GP. Among the 2315 included patients, 1908 could be analyzed for their renal function. Of these, 70.5% had an estimated glomerular filtration rate (GFR) of 89 ml/min per 1.73 m(2) or lower. One third of these patients (31.4%) were suffering from renal failure (GFRrenal status. Hypertensive patients who are seen by GP have a high level of renal disturbances and many of them do not reach recommended blood pressure values. This highlights the importance of an early detection of renal dysfunction avoiding progression towards end-stage renal failure and an adapted antihypertensive drugs prescription, such as angiotensin-converting enzyme inhibitors and angiotensin receptor blocker, acting as renal protectors.

    This study aimed to investigate the clinical feasibility and effects of percutaneous renal sympathetic nerve radiofrequency ablation in patients with heart failure. A total of 20 patients with heart failure were enrolled, aged from 47 to 75 years (63±10 years). They were divided into the standard therapy (n = 10), and renal nerve radiofrequency ablation groups (n = 10). There were 15 males and 5 female patients, including 8 ischemic cardiomyopathy, 8 dilated cardiomyopathy, and 8 hypertensive cardiopathy. All of the patients met the criteria of New York Heart Association classes III-IV cardiac function. Patients with diabetes and renal failure were excluded. Percutaneous renal sympathetic nerve radiofrequency ablation was performed on the renal artery wall under X-ray guidance. Serum electrolytes, neurohormones, and 24 h urine volume were recorded 24 h before and after the operation. Echocardiograms were performed to obtain left ventricular ejection fraction at baseline and 6 months. Heart rate, blood pressure, symptoms of dyspnea and edema were also monitored. After renal nerve ablation, 24 h urine volume was increased, while neurohormone levels were decreased compared with those of pre-operation and standard therapy. No obvious change in heart rate or blood pressure was recorded. Symptoms of heart failure were improved in patients after the operation. No complications were recorded in the study. Percutaneous renal sympathetic nerve radiofrequency ablation may be a feasible, safe, and effective treatment for the patients with severe congestive heart failure.

    To know the survival rate in patients with RIFLE I and II stages on acute renal failure, treated with supportive care or continuous renal replacement therapy with PRISMA machine, at an intensive care unit. There were included patients of both sexes, aged 16 to 69 years, with acute renal failure in RIFLE I and II stages and score of scale APACHE II lower than 36 points. The sample studied was divided in two groups: a group was treated with supportive care, and the other group received continuous renal replacement therapy via PRISMA machine. We compared mortality between both groups and the association with the RIFLE stages with Pearson's chi-squared test. The average score of the scale APACHE I was 14 points, and the probability of death was 15 %. The patients with acute renal failure RIFLE I were 54.5 % and RIFLE II 45.5 %, with mortality of 30.4 % and 38.8 %, respectively. Patients in RIFLE I stage who received supportive care and continuous replacement therapy had non-statistical differences in mortality (p = 0.356). The mortality in patients with acute renal failure in RIFLE II stage treated with continuous replacement therapy was higher (p = 0.000). Because of its accessibility and lower mortality, supportive care should be the initial procedure in patients with acute renal failure in RIFLE I and II stages.

    There is no reliable clinical test to predict the reversibility of acute-on-chronic renal failure. We study whether urinary biomarkers could be used as a noninvasive prognostic marker in patients with acute-on-chronic renal failure. We studied 39 adult patients with pre-existing chronic renal impairment presenting to us with acute-on-chronic renal failure. Urinary neutrophil gelatinase-associated lipocalin (NGAL) level was measured. The mRNA of kidney injury molecule-1 (KIM-1), interleukin-18 (IL-18), alpha-1-microglobulin (α1M), sodium/hydrogen exchanger-3 (NHE3), beta-2 microglobulin (β2M), and N-acetyl-β-D-glucosaminidase (NAG) in urinary sediment were quantified. Urinary NGAL level significantly correlated with the serum creatinine at presentation (r=0.762, pacute tubular necrosis than other causes of acute kidney injury (prenal function (r=0.387, p=0.026), as well as the estimated GFR 6 months later (r=0.386, p=0.027). In patients with acute-on-chronic renal failure, urinary NGAL level correlates with the severity of renal failure, while urinary α1M expression correlates with the degree of renal function recovery. Quantification of urinary α1M mRNA may be developed as an non-invasive tool for risk stratification of this group of patients.

    Acute decompensated heart failure is a common cause of hospitalisation. This is a period of vulnerability both in altered pathophysiology and also the potential for iatrogenesis due to therapeutic interventions. Renal dysfunction is often associated with heart failure and portends adverse outcomes. Identifying heart failure patients at risk of renal dysfunction is important in preventing progression to chronic kidney disease or worsening renal function, informing adjustment to medication management and potentially preventing adverse events. However, there is no working or consensus definition in international heart failure management guidelines for worsening renal function. In addition, there appears to be no concordance or adaptation of chronic kidney disease guidelines by heart failure guideline development groups for the monitoring of chronic kidney disease in heart failure. Our aim is to encourage the debate for an agreed definition given the prognostic impact of worsening renal function in heart failure. We present the case for the uptake of the Acute Kidney Injury Network criteria for acute kidney injury with some minor alterations. This has the potential to inform study design and meta-analysis thereby building the knowledgebase for guideline development. Definition consensus supports data element, clinical registry and electronic algorithm innovation as instruments for quality improvement and clinical research for better patient outcomes. In addition, we recommend all community managed heart failure patients have their baseline renal function classified and routinely monitored in accordance with established renal guidelines to help identify those at increased risk for worsening renal function or progression to chronic kidney disease.

    The current guidelines for 2-deoxy-2-[18F]fluoro-d-glucose PET/CT scanning do not address potential inaccuracies that may arise due to patients with renal failure. We report a retrospective analysis of standard uptake values (SUVs) in patients with and without renal failure in order to warrant a protocol adjustment. Patients were matched based on age, gender, and BMI all of which are potential effectors on observed SUV. Thirty patients were selected with clinically diagnosed renal failure, of which 12 were on dialysis. All 30 patients had age, gender, and BMI control matches. Blood urea nitrogen and creatinine levels were measured within 1 month of the scan to assess renal failure. PET/CT scans for both the renal failure patients and controls were performed 60 min after FDG injection. SUVs were measured by placing circular regions of interest in the right hepatic lobe (LSUV) and left psoas muscle (PSUV). For the 30 renal failure patients, the mean LSUV was 2.77 (SD = 0.57) and PSUV was 1.43 (SD = 0.30) while the controls had mean LSUV 2.74 (SD = 0.50) and PSUV 1.42 (SD = 0.37). The SUVs from both the liver and psoas muscle were not significantly different between the renal failure patients and the normal controls with p values >0.05. In addition, dialysis and gender also had no effect on SUVs. Our data suggest that renal failure patients do not require an adjustment in protocol and the standard protocol times should remain.

    The function of the renal nerves has been an area of scientific and medical interest for many years. The recent advent of a minimally invasive catheter-based method of renal denervation has renewed excitement in understanding the afferent and efferent actions of the renal nerves in multiple diseases. While hypertension has been the focus of much this work, less attention has been given to the role of the renal nerves in the development of chronic heart failure (CHF). Recent studies from our laboratory and those of others implicate an essential role for the renal nerves in the development and progression of CHF. Using a rabbit tachycardia model of CHF and surgical unilateral renal denervation, we provide evidence for both renal efferent and afferent mechanisms in the pathogenesis of CHF. Renal denervation prevented the decrease in renal blood flow observed in CHF while also preventing increases in Angiotensin-II receptor protein in the microvasculature of the renal cortex. Renal denervation in CHF also reduced physiological markers of autonomic dysfunction including an improvement in arterial baroreflex function, heart rate variability, and decreased resting cardiac sympathetic tone. Taken together, the renal sympathetic nerves are necessary in the pathogenesis of CHF via both efferent and afferent mechanisms. Additional investigation is warranted to fully understand the role of these nerves and their role as a therapeutic target in CHF. PMID:26300788

    Full Text Available The function of the renal nerves has been an area of scientific and medical interest for many years. The recent advent of a minimally invasive catheter-based method of renal denervation has renewed excitement in understanding the afferent and efferent actions of the renal nerves in multiple diseases. While hypertension has been the focus of much this work, less attention has been given to the role of the renal nerves in the development of chronic heart failure (CHF. Recent studies from our laboratory and those of others implicate an essential role for the renal nerves in the development and progression of CHF. Using a rabbit tachycardia model of CHF and surgical unilateral renal denervation, we provide evidence for both renal efferent and afferent mechanisms in the pathogenesis of CHF. Renal denervation prevented the decrease in renal blood flow observed in CHF while also preventing increases in Angiotensin-II receptor protein in the microvasculature of the renal cortex.

    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 VO 2 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.

    2017-11-01

    Very few cases of successful surgical treatment for renal failure due to gluteal silicone injections have been reported in the literature. The silicone toxicity and subsequent renal failure seem to follow repetitive silicone injections and silicone injections in large quantities. This is a case of a 31-year-old woman who developed renal failure after 6 years of gluteal silicone injections who underwent radical resection of bilateral gluteal regions in an attempt to mitigate her impending complete renal failure. A systematic review of the literature was conducted using PubMed database and with assistance from medical library staff to conduct keyword searches for "Silicone," "Renal failure," "Silicone emboli syndrome," "Silicone granuloma," and "Silicone end organ toxicity." The search results were reviewed by the authors and selected based on the relevance to the case report presented. Extensive literature relating to silicone granulomas and their systemic effects supports the use of steroids for immediate treatment and eventual surgical resection for cure of the various silicone-related end-organ toxicities including renal failure.

    2008-06-01

    Abnormalities in mineral metabolism and changes in skeletal histology may contribute to growth impairment in children with chronic renal failure. Hyperphosphatemia, hypocalcemia, metabolic acidosis, alterations in vitamin D and IGF synthesis and parathyroid gland dysfunction play significant roles in the development of secondary hyperparathyroidism and subsequently, bone disease in renal failure. The recent KDIGO conference has made recommendations to consider this as a systemic disorder (chronic kidney disease-mineral bone disorder) and to standardize bone histomorphometry to include bone turnover, mineralization and volume (TMV). The use of DXA to assess bone mass is controversial in children with chronic renal failure. Questions arise regarding the accuracy of bone measurements and difficulty in data interpretation especially in children with renal failure who are not only growth retarded but often have pubertal delay and osteosclerosis. The validity and feasibility of new modalities of skeletal imaging which can detect changes in both trabecular and cortical bone are currently being investigated in children. The management of mineral abnormalities and bone disease in chronic renal failure is multifactorial. To manage hyperphosphatemia, dietary phosphate restriction accompanied by intake of calcium-free and metal-free phosphate binding agents are widely utilized. Vitamin D analogs remain the primary therapy for secondary hyperparathyroidism, although the use of the less hypercalcemic agents is preferred due to concerns of calciphylaxis and vascular calcification. Future clinical studies are needed to evaluate the long-term effects of calcimimetic agents and bisphosphonate therapy in children with chronic renal failure.

    Renal dysfunction has been proposed for the risk factor for stroke and bleeding in atrial fibrillation (AF). The impact of changes in renal dysfunction over time and the relationship to stroke and bleeding risk in these patients remain unknown. We investigated sequential change in renal function (estimated glomerular filtration rate, eGFR) and the risk for clinical events (ischaemic stroke, death and major bleeding) over time in a cohort of 617 AF patients followed up for 2 years. eGFR was estimated at baseline, 6 months and 12 months using three formulas (Modification of Diet in Renal Disease equation, MDRD, Chronic Kidney Disease Epidemiology Collaboration, CKD-EPI, and Cockcroft-Gault equation). Changes in eGFR and the risk for clinical events were analysed by Cox models, receiver operating curves (ROC), and Kaplan-Meier survival curves. When patients with eGFR≤60 ml/min/1.73 m(2) were compared to patients with eGFR>60 ml/min/1.73 m(2), there was an increase over time in stroke or death, or death, with impaired renal function (all pstroke or death, death, and ischaemic stroke at 6 months (all pstroke or death in patients with AF (c-indexes: 0.57 to 0.61, pstroke or death', 'death' or (at 6 months) ischaemic stroke.

    The information available on the incidence and the characteristics of patients with acute renal failure (ARF) related to drugs is scarce. To estimate the incidence of drug-related ARF in hospitalised patients and to compare their characteristics with those of patients with ARF due to other causes. We selected a prospective cohort of patients with ARF during hospital admission (July 2010-July 2011). Information on patients' demographics, medical antecedents, ARF risk factors, ARF severity according to the RIFLE classification and hospital drug administration was collected. We analysed the relationship of drugs with the ARF episodes using Spanish Pharmacovigilance System methods and algorithm. A total of 194 cases had an episode of hospital-acquired ARF. The median age of patients was 72 years [IQR 20]; 60% were men. The ARF incidence during hospitalization was 9.6 per 1,000 admissions. According to the RIFLE classification, a risk of kidney damage or kidney injury was present in 77.8% of cases. In 105 (54.1%) cases, ARF was drug-related; the drugs most frequently involved were diuretics, agents acting on the renin-angiotensin system, immunosuppressants, β-blocking agents, calcium channel blockers, contrast media and non-steroid anti-inflammatory drugs. Patients with drug-related ARF had more multi-morbidity, fewer ARF risk factors and lower mortality. Half of ARF episodes during hospitalisation were drug related. Patients with drug-related ARF had higher cardiovascular morbidity than those with ARF related to other causes, but they had a lower frequency of ARF risk factors and mortality.

    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

    2017-10-01

    Background and purpose The prevalence of chronic kidney disease (estimated glomerular filtration rate (eGFR) chronic kidney disease (CKD)) in ischemic stroke and transient ischemic attack (TIA) is unknown, as estimates have been based on single-point estimates of renal function. Studies investigating the effect of renal dysfunction (eGFR < 60 mL/min per 1.73 m 2 , renal dysfunction) on post-stroke outcomes are limited to hospitalized cohorts and have provided conflicting results. Methods We investigated rates, determinants and outcomes of renal dysfunction in ischemic stroke and TIA in the North Dublin Population Stroke Study. We also investigate the persistence of renal dysfunction in 90-day survivors to determine the prevalence of CKD. Ascertainment included hot and cold pursuit using multiple overlapping sources. Survival analysis was performed using Kaplan-Meier survival curves and Cox proportional hazards modeling. Results In 547 patients (ischemic stroke in 76.4%, TIA in 23.6%), the mean eGFR at presentation was 63.7 mL/min/1.73 m 2 (SD 22.1). Renal dysfunction was observed in 44.6% (244/547). Among 90-day survivors, 31.2% (139/446) met criteria for CKD. After adjusting for age and stroke severity, eGFR < 45 mL/min/1.73 m 2 (hazard ratio 2.53, p = 0.01) independently predicted 28-day fatality but not at two years. Poor post-stroke functional outcome (Modified Rankin Scale 3-5) at two years was more common in those with renal dysfunction (52.5% vs. 20.6%, p < 0.001). After adjusting for age, stroke severity and pre-stroke disability, renal dysfunction (OR 2.17, p = 0.04) predicted poor functional outcome. Conclusion Renal dysfunction and CKD are common in ischemic stroke and TIA. Renal dysfunction is associated with considerable post-stroke morbidity and mortality. Further studies are needed to investigate if modifiable mechanisms underlie these associations.

    In rats with genetically hypoplastic kidneys (hpk/hpk) and associated hypogonadism (hgn/hgn), their kidneys contain only one-quarter the number of nephrons that are found in those of normal rats [26]. Not surprisingly, therefore, renal excretive function has been shown to be depressed in hpk/hpk rats [26]. In the study presented here, we have examined the process of the progression of renal failure and the development of renal secondary disease in hpk/hpk rats. The plasma concentrations of urea-nitrogen and creatinine were significantly higher in adult hpk/hpk rats than in normal rats. These values elevated gradually and the degree of renal histological damage also progressed with advancing age in the hpk/hpk rats. In addition, renal anemia appeared at 140 days of age or later in these rats, and hyperplasia of the parathyroid glands was visible macroscopically at 280 days of age. In the hpk/hpk rats plasma levels of calcium and phosphorus were significantly lower and higher than in normal rats, respectively, at 280 days of age. Pathologically, the left femora of hpk/hpk rats exhibited fibrous osteodystrophy at 280 days of age and the calcium content of the right femora (as a percentage of the dry weight of bone) was significantly lower than in normal rats at both 210 and 280 days of age. These results indicate that the reduced nephrogenesis of the hpk/hpk rats causes progressive renal failure, secondarily inducing anemia, hyperparathyroidism, and osteodystrophy.

Besides, on the growth rate and expected family size, to intervene or prevent them in future cases. Also, the use that has given in the hospital to growth hormone, before and after renal transplantation is determined to eventually use parallel therapies to the transplantation. An echocardiographic study is recommended to perform as part of the treatment of chronic renal failure to identify the existence of left ventricular hypertrophy and heart failure, which may occur as a result of complications of the failure [es

    Full Text Available Renal zygomycosis, caused by invasive fungi, is a rare and potentially fatal infec-tion. The patient usually presents with non-specific symptoms and renal failure. A 34-year-old male non-diabetic and without any predisposing factors for systemic fungal infection presented to the emergency department with diffuse abdominal pain, high-grade fever and acute renal failure with a serum creatinine of 6.5. A computed tomography showed bilateral diffuse globular nephromegaly. A urine smear for fungal examination showed right angle branching hyphae and kidney biopsy showed fungal hyphae within the glomeruli, tubules and interstitium. Although radiological investigations can give us a clue, the definitive diagnosis can only be made by kidney biopsy. A high index of suspicion and timely diagnosis is important for a proper management.

    Pretransplant renal failure is commonly reported to be a poor prognostic indicator affecting survival after liver transplantation (LT). However, whether the impact of renal failure on patient outcome varies according to the aetiology of the underlying liver disease is largely unknown. We investigated the association between renal failure at the time of LT and patient outcome in patients with alcoholic liver disease (ALD) (n = 6920), non-alcoholic steatohepatitis (NASH) (n = 2956) and hepatitis C (HCV) (n = 14 922) using the United Network for Organ Sharing (UNOS) database between February 2002 and December 2013. A total of 24 798 transplant recipients were included. The presence of renal failure was more frequently seen in patients with ALD (23.95%) and NASH (23.27%) compared to patients with HCV (19.38%) (P renal failure was an independent predictor of poor survival. Renal failure showed detrimental effect on patient survival in the overall series (HR = 1.466, P renal failure was less marked in patients with ALD (HR = 1.31, P renal failure had better long-term prognosis than non-ALD patients. Renal failure at the time of LT conferred a lower patient and graft survival post-LT. However, renal failure has less impact on the outcome of patients with ALD than that of patients with non-alcoholic liver disease after LT. © 2016 John Wiley & Sons A/S.

    Context: There is a need for identifying risk factors aggravating development of acute renal failure after attaining trauma and defining new parameters for better assessment and management. Aim of the study was to determine the incidence of acute renal failure among trauma patients, and its correlation with various laboratory and clinical parameters recorded at the time of admission and in-hospital mortality. Subjects and Methods: The retrospective cohort study included admitted 208 trauma patients over a period of one year. 135 trauma patients at the serum creatinine level >2.0 mg/dL were enrolled in under the group of acute renal failure. 73 patients who had normal creatinine level made the control group. They were further assessed with clinical details and laboratory investigations. Results: Incidence of acute renal failure was 3.1%. There were 118 (87.4%) males and average length of stay was 9 (1, 83) days. Severity of injury (ISS, GCS) was relatively more among the renal failure group. Renal failure was transient in 35 (25.9%) patients. They had higher incidence of bone fracture (54.0%) (P= 0.04). Statistically significant association was observed between patients with head trauma and mortality 72 (59.0%) (P= 0.001). Prevalence of septic 24 (59.7%) and hemorrhagic 9 (7.4%) shock affected the renal failure group. Conclusion: Trauma patients at the urea level >50 mg/dL, ISS >24 on the first day of admission had 23 times and 7 times the risk of developing renal failure. Similarly, patients with hepatic dysfunction and pulmonary dysfunction were 12 times and 6 times. Patients who developed cardiovascular dysfunction, hematological dysfunction and post-trauma renal failure during the hospital stay had risk for mortality 29, 7 and 8 times, respectively. The final prognostic score obtained was: 14*hepatic dysfunction + 11*cISS + 18*cUrea + 12*cGlucose + 10*pulmonary dysfunction. Optimal score cut-off for prediction of renal failure was found to be ≥25 with

    This case report describes a 54-year-old, asymptomatic man who presented with hyperkalemia on routine lab testing who was later found to have acute renal failure, unresponsive to fluid resuscitation, with minimal improvement after hemodialysis. After a comprehensive evaluation ruled out common causes of acute renal failure, the patient underwent testing with a bone survey, urine protein electrophoresis (UPEP), serum protein electrophoresis (SPEP), and immunoelectrophoresis for suspected plasma cell dyscrasia and received plasmapheresis for hyperviscosity syndrome and nephrotoxicity, which resulted in improved renal function. Lab results showed monoclonal gammopathy, elevated serum free light chains, and Bence Jones protein in the urine with a follow-up bone marrow biopsy indicating plasma cell dyscrasia. The patient received a diagnosis of multiple myeloma (MM) and was started on chemotherapy and immunosuppression. In patients presenting with acute renal failure with an evaluation ruling out prerenal and postrenal causes, multiple myeloma should be considered.

    Aim: Chronic kidney disease (CKD) is often associated with a disturbed cardiovascular homeostasis. This investigation explored the role of the renal innervation in mediating deranged baroreflex control of renal sympathetic nerve activity (RSNA) and renal excretory function in cisplatin-induced renal failure. Methods: Rats were either intact or bilaterally renally denervated 4 days prior to receiving cisplatin (5 mg/kg i.p.) and entered a chronic metabolic study for 8 days. At day 8, other groups of rats were prepared for acute measurement of RSNA or renal function with either intact or denervated kidneys. Results: Following the cisplatin challenge, creatinine clearance was 50% lower while fractional sodium excretion and renal cortical and medullary TGF-β1 concentrations were 3–4 fold higher in both intact and renally denervated rats compared to control rats. In cisplatin-treated rats, the maximal gain of the high-pressure baroreflex curve was only 20% that of control rats, but following renal denervation not different from that of renally denervated control rats. Volume expansion reduced RSNA by 50% in control and in cisplatin-treated rats but only following bilateral renal denervation. The volume expansion mediated natriuresis/diuresis was absent in the cisplatin-treated rats but was normalized following renal denervation. Conclusions: Cisplatin-induced renal injury impaired renal function and caused a sympatho-excitation with blunting of high and low pressure baroreflex regulation of RSNA, which was dependent on the renal innervation. It is suggested that in man with CKD there is a dysregulation of the neural control of the kidney mediated by its sensory innervation. PMID:26175693

    The effects of PA21, a novel iron-based and non-calcium-based phosphate binder, on hyperphosphatemia and its accompanying bone abnormality in chronic kidney disease-mineral and bone disorder (CKD-MBD) were evaluated. Rats with adenine-induced chronic renal failure (CRF) were prepared by feeding them an adenine-containing diet for four weeks. They were also freely fed a diet that contained PA21 (0.5, 1.5, and 5%), sevelamer hydrochloride (0.6 and 2%) or lanthanum carbonate hydrate (0.6 and 2%) for four weeks. Blood biochemical parameters were measured and bone histomorphometry was performed for femurs, which were isolated after drug treatment. Serum phosphorus and parathyroid hormone (PTH) levels were higher in the CRF rats. Administration of phosphate binders for four weeks decreased serum phosphorus and PTH levels in a dose-dependent manner and there were significant decreases in the AUC0-28 day of these parameters in 5% PA21, 2% sevelamer hydrochloride, and 2% lanthanum carbonate hydrate groups compared with that in the CRF control group. Moreover, osteoid volume improved significantly in 5% of the PA21 group, and fibrosis volume and cortical porosity were ameliorated in 5% PA21, 2% sevelamer hydrochloride, and 2% lanthanum carbonate hydrate groups. These results suggest that PA21 is effective against hyperphosphatemia, secondary hyperparathyroidism, and bone abnormalities in CKD-MBD as sevelamer hydrochloride and lanthanum carbonate hydrate are, and that PA21 is a new potential alternative to phosphate binders.

    To establish the effect of continuous renal replacement therapy on outcome in pediatric acute liver failure. Retrospective cohort study. Sixteen-bed PICU in a university-affiliated tertiary care hospital and specialist liver centre. All children (0-18 yr) admitted to PICU with pediatric acute liver failure between January 2003 and December 2013. Children with pediatric acute liver failure were managed according to a set protocol. The guidelines for continuous renal replacement therapy in pediatric acute liver failure were changed in 2011 following preliminary results to indicate the earlier use of continuous renal replacement therapy for both renal dysfunction and detoxification. Of 165 children admitted with pediatric acute liver failure, 136 met the inclusion criteria and 45 of these received continuous renal replacement therapy prior to transplantation or recovery. Of the children managed with continuous renal replacement therapy, 26 (58%) survived: 19 were successfully bridged to liver transplantation and 7 spontaneously recovered. Cox proportional hazards regression model clearly showed reducing hyperammonemia by 48 hours after initiating continuous renal replacement therapy significantly improved survival (HR, 1.04; 95% CI, 1.013-1.073; p = 0.004). On average, for every 10% decrease in ammonia from baseline at 48 hours, the likelihood of survival increased by 50%. Time to initiate continuous renal replacement therapy from PICU admission was lower in survivors compared to nonsurvivors (HR, 0.96; 95% CI, 0.916-1.007; p = 0.095). Change in practice to initiate early and high-dose continuous renal replacement therapy led to increased survival with maximum effect being visible in the first 14 days (HR, 3; 95% CI, 1.0-10.3; p = 0.063). Among children with pediatric acute liver failure who did not receive a liver transplant, use of continuous renal replacement therapy significantly improved survival (HR, 4; 95% CI, 1.5-11.6; p = 0.006).

    Renal failure as a consequence of eating mushrooms has been reported repeatedly after ingestion of webcaps of the Cortinarius orellanus group. But mushrooms of the genus Amanita can also cause renal failure: Amanita smithiana (North America) and Amanita proxima (Mediterranean area). Here, we discuss poisonings caused by other white amanitas. A German and--independently--two Portuguese patients reported the ingestion of completely white mushrooms with ring. Similar to intoxications with A. smithiana or A. proxima, the clinical picture was characterized by nausea and vomiting 10-12 h after ingestion, severe acute renal failure and mild hepatitis. Renal biopsy showed acute interstitial nephritis and tubular necrosis. Two patients were given temporary haemodialysis. All have fully recovered their renal function. Poisonings caused by mushrooms containing the toxin of A. smithiana were suspected. We tested 20 Amanita species for the presence of this toxin. Thin layer chromatography was applied to detect A. smithiana nephrotoxin in herbarium specimens using authentic material of A. smithiana as reference. A. smithiana toxin could be detected in Amanita boudieri, Amanita gracilior and in Amanita echinocephala. A. boudieri was collected by the Portuguese patients. A. echinocephala is the only nephrotoxic Amanita growing North of the Alps and is suspected to be the cause of renal failure in the German patient. No A. smithiana toxin was detectable in the nephrotoxic A. proxima. A. boudieri, A. gracilior and A. echinocephala are nephrotoxic. These intoxications are clinically similar to that of A. smithiana, with acute reversible renal failure and mild hepatitis but are different in their clinical picture from Orellanus syndrome characterized by a delayed onset of severe and often irreversible renal failure.

    Full Text Available The aim of this study was to analyse the demographic variables of chronic non-terminal (CRF and terminal (TRF renal failure patients (pts younger than 19 years treated in Serbia in June 2001. 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

    The aim of this study was to evaluate the changes in salivary gland function in patients with chronic renal failure (CRF) undergoing hemodialysis. The group consisted of 23 patients with CRF (13 female, 10 male; mean age: 40{+-}13 yr) and 14 healthy control subjects (mean age: 40{+-}13 yr). All underwent dynamic salivary gland scintigraphy with gustatory stimulation. After intravenous administration of {sup 99m}Tc pertechnetate, first, perfusion images at 2 seconds per frame were acquired for 1 minute, then dynamic images at 1 minute per frame were acquired for 45 minutes. At 30 minutes after injection , 10 ml lemon juice was given for 15 minutes as a gustatory stimulus. We obtained time-activity curves derived from regions of interest centered over the four major salivary glands. The following functional indices were calculated for each gland: the time of maximum radioactivity (T{sub max}) for the prestimulated period, the time of minimum radioactivity (T{sub min}), as an indicator of velocity of secretion after stimulation, and the Lem E{sub 5}% value as an indicator of the secretion function. When the patients with CRF undergoing hemodialysis were compared to the controls, there were statistically significant differences in T{sub max}, T{sub min} and Lem E{sub 5}% values for bilateral parotid glands, and T{sub min} values for bilateral submandibular glands (p<0.05), there were no statistically significant differences in T{sub max} and Lem E{sub 5}% values for bilateral submandibular glands. There were also significant differences in T{sub max} and Lem E{sub 5}% values for bilateral parotid glands between mild oral problems and severe oral problems in patients with CRF (undergoing hemodialysis). In this study, prolonged T{sub max} and T{sub min} values, and decreased Lem E{sub 5}% values for parotid glands and prolonged T{sub min} values for submandibular glands on salivary scintigraphy pointed out decreased parenchymatous and excretory function in patients with

    Heart failure (HF) is associated with poor cardiac outcomes and mortality. It is not known whether HF leads to poor renal outcomes in patients with normal kidney function. We hypothesized that HF is associated with worse long-term renal outcomes. Among 3 570 865 US veterans with estimated glomerular filtration rate (eGFR) ≥60 mL min -1 1.73 m -2 during October 1, 2004 to September 30, 2006, we identified 156 743 with an International Classification of Diseases , Ninth Revision , diagnosis of HF. We examined the association of HF with incident chronic kidney disease (CKD), the composite of incident CKD or mortality, and rapid rate of eGFR decline (slopes steeper than -5 mL min -1 1.73 m -2 y -1 ) using Cox proportional hazard analyses and logistic regression. Adjustments were made for various confounders. The mean±standard deviation baseline age and eGFR of HF patients were 68±11 years and 78±14 mL min -1 1.73 m -2 and in patients without HF were 59±14 years and 84±16 mL min -1 1.73 m -2 , respectively. HF patients had higher prevalence of hypertension, diabetes mellitus, cardiac, peripheral vascular and chronic lung diseases, stroke, and dementia. Incidence of CKD was 69.0/1000 patient-years in HF patients versus 14.5/1000 patient-years in patients without HF, and 22% of patients with HF had rapid decline in eGFR compared with 8.5% in patients without HF. HF patients had a 2.12-, 2.06-, and 2.13-fold higher multivariable-adjusted risk of incident CKD, composite of CKD or mortality, and rapid eGFR decline, respectively. HF is associated with significantly higher risk of incident CKD, incident CKD or mortality, and rapid eGFR decline. Early diagnosis and management of HF could help reduce the risk of long-term renal complications. © 2017 American Heart Association, Inc.

    In the last 10 years approximately 250 cases were registered in which acute deterioration of the renal function occurred after the application of radioopaque media. On the average, renal functionability is impaired in every 20th patient. A high risk factor is a previously existing renal insufficiency. Also in diabetes mellitus with renal insufficiency almost regularly an impairment is observed. A possible existing dehydration must be compensated before the contrast medium is administered. Also in patients with plasmocytoma the prognosis is unfavourable. Other risk factors are higher age (over 50 years), higher doses and an existing cardiac insufficiency. Finally, recommendations are given, which concern the previous detection of possible risk factors and the performance of the examination. (MG) [de

    Over a million patients get hospitalized with the diagnosis of acute decompensated heart failure which poses an insurmountable financial burden on the health care system. Heart failure alone incurs over 30 billion dollars with half the cost spent towards acute hospitalizations. Majority of the treatment strategies have focused towards decongesting patients which often comes with the cost of worsening renal function. Renal dysfunction in the setting of acute decompensated heart failure portends worse morbidity and mortality. Recently, there has been a change in the focus with shift towards therapies attempting to conserve renal function. In the past decade, we have witnessed several large randomized controlled trials testing the established as well as emerging therapies in this subset of population with mixed results. This review intends to provide a comprehensive overview of the pharmacologic therapies commonly utilized in the management of acute decompensated heart failure and the body of evidence supporting these strategies.

    Chronic renal failure (CRF) is histopathologically characterized by tubulointerstitial fibrosis in addition to glomerulosclerosis. Although mast cells are known to infiltrate into the kidneys with chronic inflammation, we know little about their contribution to the pathogenesis of renal fibrosis associated with CRF. The aim of this study was to reveal the involvement of mast cells in the progression of renal fibrosis in CRF. Using a rat model with CRF resulting from 5/6 nephrectomy, we examined the histopathological features of the kidneys and the infiltration of mast cells into the renal interstitium. By treating the rats with a potent mast cell stabilizer, tranilast, we also examined the involvement of mast cells in the progression of renal fibrosis associated with CRF. The CRF rat kidneys were characterized by the wide staining of collagen III and increased number of myofibroblasts, indicating the progression of renal fibrosis. Compared to T-lymphocytes or macrophages, the number of tryptase-positive mast cells was much smaller within the fibrotic kidneys and they did not proliferate in situ. The mRNA expression of mast cell-derived fibroblast-activating factors was not increased in the renal cortex isolated from CRF rat kidneys. Treatment with tranilast did not suppress the progression of renal fibrosis, nor did it ameliorate the progression of glomerulosclerosis and the interstitial proliferation of inflammatory leukocytes. This study demonstrated for the first time that mast cells are neither increased nor activated in the fibrotic kidneys of CRF rats. Compared to T-lymphocytes or macrophages that proliferate in situ within the fibrotic kidneys, mast cells were less likely to contribute to the progression of renal fibrosis associated with CRF. © 2016 Asian Pacific Society of Nephrology.

    Full Text Available Abstract Introduction – Acute renal failure (ARF has a poor prognosis in patients with cancer requiring intensive care unit (ICU admission. Our aim is finding prognostic factors for hospital mortality in patients with cancer with ARF requiring renal replacement therapy (RRT. Methods – In this retrospective study, all patients with cancer with ARF treated with continuous venovenous filtration (CVVHDF in the ICU of the Institut Jules Bordet, between January 1st 2003 and December 31st 2012, were included in the study.Results – 103 patients are assessed: men/women 69/34, median age 62 years, solid/haematologic tumours 68/35, median SAPS II 56. Mortality rate was 63%. Seven patients required chronic renal dialysis. After multivariate analysis, two variables were statistically associated with hospital mortality : more than one organ failure (including kidney (OR 5.918 ; 95% CI 2.184 – 16.038 ; p<0,001 and low albumin level (OR 3.341; 95% CI 1.229 – 9.077; p=0,02. Only minor complications related to CVVHDF have been documented.Conclusions – Despite the poor prognosis associated with ARF, CVVHDF is an effective and tolerable renal replacement technique in patients with cancer admitted to the ICU. Multiple organ failure and hypoalbuminemia, two independent prognostic factors for hospital mortality have to be considered when deciding for introducing RRT.

    How cardiovascular (CV) events affect progression to end-stage renal disease (ESRD), particularly in the setting of type 2 diabetes, remains uncertain. Observational study. 4,022 patients with type 2 diabetes, anemia, and chronic kidney disease from the Trial to Reduce Cardiovascular Events With Aranesp Therapy (TREAT). Postrandomization CV events. ESRD (defined as initiation of dialysis for >30 days, kidney transplantation, or refusal or nonavailability of renal replacement therapy) and post-ESRD mortality within 30 days and during overall follow-up after an intercurrent CV event. Population limited to clinical trial participants with diabetes and anemia. 155 of 652 (23.8%) ESRD cases occurred after an intercurrent CV event; 110 (16.9%) cases followed heart failure, 28 (4.3%) followed myocardial infarction, 12 (1.84%) followed stroke, and 5 (0.77%) followed multiple CV events. ESRD rate was higher within 30 days in individuals with an intercurrent CV event compared with those without an intercurrent event (HR, 22.2; 95% CI, 17.0-29.0). Compared to no intercurrent CV events, relative risks for ESRD were higher after the occurrence of heart failure overall (HR, 3.4; 95% CI, 2.7-4.2) and at 30 days (HR, 20.1; 95% CI, 14.5-27.9) than after myocardial infarction or stroke (Pfailure, are strongly associated with risk for ESRD. These findings underscore the need for kidney-specific therapies in addition to treatment of CV risk factors to lower ESRD incidence in diabetes. Copyright © 2017 National Kidney Foundation, Inc.

    Renal function impairment predicts poor survival in heart failure. Attention has recently shifted to worsening renal function, based mostly on serum creatinine and estimated glomerular filtration rate. We assessed the prognostic effect of worsening renal function in ambulatory heart failure patients. Data from 306 ambulatory patients were abstracted from medical files. Worsening renal function was based on the change in estimated glomerular filtration rate, serum creatinine and urea within 6 months of referral. Prognosis was assessed by the composite endpoint all-cause death or heart failure hospitalization, censored at 2 years. Hazard ratios were estimated for worsening renal function, adjusted for sex, age, diabetes, New York Heart Association class, left ventricular systolic dysfunction, medications and baseline renal function. The agreement among definitions was fair, with kappa coefficients generally not surpassing 0.5. Worsening renal function was associated with poor outcome with adjusted hazard ratios (95% confidence interval) of 3.2 (1.8-5.9) for an increase of serum creatinine >0.3mg/dl; 2.2 (1.3-3.7) for an increase in serum urea >20mg/dl and 1.9 (1.1-3.3) for a decrease in estimated glomerular filtration rate >20%, independent of baseline renal function. The 2-year risk of death/heart failure hospitalization was approximately 50% in patients with an increase in serum creatinine or in serum urea; this positive predictive value was higher than for decreasing estimated glomerular filtration rate. In conclusion, worsening renal function was significantly associated with a worse outcome. Different definitions identified different patients at risk and increasing creatinine/urea performed better than decreasing estimated glomerular filtration rate.

    Renal dysfunction is associated with increased long-term mortality and incidence of myocardial infarction following coronary artery bypass grafting (CABG). Little is known about the relationship between renal dysfunction and long-term risk of stroke following CABG. All 29 057 patients who underwent primary isolated CABG from 2000 through 2008 in Sweden, with no myocardial infarction within 14 days before surgery and no prior stroke, were included from the SWEDEHEART registry. During a mean follow-up of 4.5 years, there were 1563 (5.4%) first strokes (74% ischemic, 8% hemorrhagic, and 18% unspecified). Glomerular filtration rates (eGFR) were estimated using the Modification of Diet in Renal Disease equation. Hazard ratios (HR) with 95% confidence intervals (CI) were calculated for stroke in relation to eGFR. Adjusted HR for all stroke in patients with eGFR 45 to 60, 30 to 45 and 15 to 30 mL/min/1.73 m(2) were; 1.17 (1.03 to 1.34), 1.52 (1.25 to 1.85) and 1.79 (1.20 to 2.65), respectively compared to patients with eGFR >60 mL/min/1.73 m(2). Gender-specific analysis did not show any major differences between men and women. The adjusted risk of hemorrhagic stroke was somewhat higher than for ischemic stroke: HR 2.07 (1.15 to 3.73) vs. 1.55 (1.26 to 1.91), in patients with eGFR 15 to 45 mL/min/1.73 m(2). Renal dysfunction is associated with increased long-term risk of stroke after primary isolated CABG. The impact of renal dysfunction on risk of stroke appears to be similar for both men and women.

    Male, 78. Acute myeloid leukemia (AML). Dyspnea • fatigue. Idarubicin followed by cytarabine. Chemotherapy. Hematology. Unusual clinical course. Renal failure is a common presentation of acute myelomonocytic and monocytic leukemia. It is usually the result of a combined glomerular and tubular dysfunction and is associated with a poor prognosis. No guidelines exist for treatment. We herein describe the case of a 78-year-old Caucasian man who presented with acute myeloid leukemia M5, leukostasis with a white count of 340 000/ml, and acute renal failure with a creatinine of 7.7/dL. The patient was initially treated with leukapheresis and 3 days of idarubicin in the setting of continuous renal replacement therapy that resulted in rapid reversal of his renal failure. He then received 7 days of continuous infusion cytarabine and went into a complete remission. Renal failure may complicate the presentation of AML but can be reversible with treatment. Dose adjustment of the chemotherapy is not needed and the treatment can be greatly facilitated with the use of continuous renal replacement therapy, as indicated in our case report. In addition, we emphasize that organ dysfunction, even in elderly patients, is not necessarily a contraindication to aggressive treatment if it is felt to be disease-related and reversible.

    Renal failure is a frequent complication in liver transplant recipients and is associated with increased morbidity and mortality. A variety of risk factors for the development of renal failure in the pre- and post-transplantation periods have been described, as well as at the time of surgery. To reduce the negative impact of renal failure in this population, an active approach is required for the identification of those patients with risk factors, the implementation of preventive strategies, and the early detection of progressive deterioration of renal function. Based on published evidence and on clinical experience, this document presents a series of recommendations on monitoring RF in LT recipients, as well as on the prevention and management of acute and chronic renal failure after LT and referral of these patients to the nephrologist.

    Studies have shown that iodinated radiocontrast use is associated with acute renal failure especially in the presence of chronic kidney disease and multiple factors modulate this risk. The purpose of this meta-analysis is to compare the incidence of renal failure requiring hemodialysis between transfemoral (TF) and transapical (TA) transcatheter aortic valve replacement using the Edwards valve. The PubMed database was searched from January 2000 through December 2014. A total of 10 studies (n = 2,459) comparing TF (n = 1,268) and TA (n = 1,191) TAVR procedures using the Edwards valve were included. Variables of interest were baseline logistic EuroSCORE, prevalence of diabetes mellitus, hypertension, peripheral arterial disease, chronic kidney disease and amount of contrast used. The primary endpoint was incidence of renal failure requiring hemodialysis. The odds ratio and 95% CI were computed and P renal failure requiring hemodialysis was higher with the Edwards valve. This suggests that the incidence of renal failure requiring hemodialysis after TAVR is associated with baseline comorbidities in the TA-TAVR group rather than the volume of contrast used.

    Background: Heart Failure (HF) is a common disease with a high mortality rate. Anaemia and renal failure (RF) are often present in patients with HF and associated with worse prognosis. Objective of study was to evaluate the prevalence of anaemia and RF in patients with HF. Methods: Patients admitted in Punjab institute of cardiology Lahore with diagnosis of heart failure were enrolled from February, 2008 to December, 2008. Anaemia was defined as haemoglobin levels <13 mg/dl for men and 12 mg/dl for women. Renal function was assessed by the glomerular filtration rate (GFR), calculated by the simplified formula of the MDRD (Modification of Diet in Renal Disease) study. Results : Of the 276 patients included in this study, 42.03% (116) had anaemia and 38.40% (106) had moderate to severe renal failure (GFR <60 ml/min). Conclusion: The prevalence of anaemia and renal failure was high in this population and was associated with the severity of the HF (functional classes III and IV). (author)

    To assess the outcome of patients with renal failure presenting to a regional nephrology unit. The records of patients with plasma creatinine concentration > or = 0.30 mmol/L who presented between 1 January 1988 and 31 December 1993, or were already under follow up, were studied. The outcome of 491 patients (293 males) aged from 4.8 to 88.8 years, 123 of whom had acute renal failure, was assessed at 30 June 1994. Thirty seven (30%) of the patients with acute renal failure had died. Of the 372 patients with chronic renal failure 139 had started regular dialysis treatment and 95 were dead, including 27 patients, with a mean age of 71 years, who died of untreated end-stage renal failure (ESRF). For 11 (40%) of these patients the patient and/or family made the decision not to start dialysis treatment. The rates of treatment of ESRF are lower in Canterbury and Westland than those in the Auckland region. The latter can be explained partly by the differences in the demography of the respective populations. Death from untreated ESRF is uncommon in Canterbury and Westland. The rates of treatment of ESRF with regular dialysis are lower than in the Auckland region.

    Frequency of pulmonary complications after renal transplant has been reported to range from 3% to 17%. The objective of this study was to evaluate renal transplant recipients admitted to an intensive care unit to identify incidence and cause of acute respiratory failure in the postoperative period and compare clinical features and outcomes between those with and without acute respiratory failure. We retrospectively screened the data of 540 consecutive adult renal transplant recipients who received their grafts at a single transplant center and included those patients admitted to an intensive care unit during this period for this study. Acute respiratory failure was defined as severe dyspnea, respiratory distress, decreased oxygen saturation, hypoxemia or hypercapnia on room air, or requirement of noninvasive or invasive mechanical ventilation. Among the 540 adult renal transplant recipients, 55 (10.7%) were admitted to an intensive care unit, including 26 (47.3%) admitted for acute respiratory failure. Median time from transplant to intensive care unit admission was 10 months (range, 0-67 mo). The leading causes of acute respiratory failure were bacterial pneumonia (56%) and cardiogenic pulmonary edema (44%). Mean partial pressure of arterial oxygen to fractional inspired oxygen ratio was 174 ± 59, invasive mechanical ventilation was used in 13 patients (50%), and noninvasive mechanical ventilation was used in 8 patients (31%). The overall mortality was 16.4%. Acute respiratory failure was the reason for intensive care unit admission in almost half of our renal transplant recipients. Main causes of acute respiratory failure were bacterial pneumonia and cardiogenic pulmonary edema. Mortality of patients admitted for acute respiratory failure was similar to those without acute respiratory failure.

    Atsushi Yaguchi

    Full Text Available The effects of PA21, a novel iron-based and non-calcium-based phosphate binder, on hyperphosphatemia and its accompanying bone abnormality in chronic kidney disease-mineral and bone disorder (CKD-MBD were evaluated. Rats with adenine-induced chronic renal failure (CRF were prepared by feeding them an adenine-containing diet for four weeks. They were also freely fed a diet that contained PA21 (0.5, 1.5, and 5%, sevelamer hydrochloride (0.6 and 2% or lanthanum carbonate hydrate (0.6 and 2% for four weeks. Blood biochemical parameters were measured and bone histomorphometry was performed for femurs, which were isolated after drug treatment. Serum phosphorus and parathyroid hormone (PTH levels were higher in the CRF rats. Administration of phosphate binders for four weeks decreased serum phosphorus and PTH levels in a dose-dependent manner and there were significant decreases in the AUC0-28 day of these parameters in 5% PA21, 2% sevelamer hydrochloride, and 2% lanthanum carbonate hydrate groups compared with that in the CRF control group. Moreover, osteoid volume improved significantly in 5% of the PA21 group, and fibrosis volume and cortical porosity were ameliorated in 5% PA21, 2% sevelamer hydrochloride, and 2% lanthanum carbonate hydrate groups. These results suggest that PA21 is effective against hyperphosphatemia, secondary hyperparathyroidism, and bone abnormalities in CKD-MBD as sevelamer hydrochloride and lanthanum carbonate hydrate are, and that PA21 is a new potential alternative to phosphate binders.

    Full Text Available OBJECTIVE: Mannitol is an osmotic diuretic agent and reduces intracranial pressure. The most serious side effect of mannitol is kidney dysfunction. In this study, renal functions in acute stroke patients treated with mannitol were evaluated. METHODS: One hundred and twenty-two patients followed in the neurology intensive care unit with the diagnosis of stroke and treated with fractionated mannitol for 5 days were evaluated retrospectively. Ninety-six patients had ischemic and 26 had hemorrhagic stroke. Mean age was 69.9 ± 11.8 (18-91 years. Serum urea, creatinine and electrolyte levels measured before and on the second, third, fourth, fifth and tenth days of treatment were compared statistically with paired sample t test. RESULTS: The average urea and creatinine levels on the second, third, fourth and fifth days of treatment were significantly higher than the baseline (p< 0.05. On the other hand, mannitol treatment did not change average sodium, potassium and chlorine levels. The creatinine levels had returned to the normal range on the tenth day of treatment, but the urea levels, although decreased, did not fall to the normal range. CONCLUSION: Our results support the view that close monitoring of renal function is necessary in patients treated with mannitol

    Full Text Available Acute renal failure is a life threatening condition. Nonsteroidal antiinflammatory drugs (NSAIDs and cephalosporins are widely used postoperative drugs. NSAID-induced acute renal failure has been reported in the past. In this case, drug interaction and decompensated state of the patient precipitate the condition. NSAIDs inhibit prostaglandins synthesis and thus aggravate ischemia to the kidney that is already facing volume crisis due to surgery. Due to renal dysfunction, plasma ceftriaxone level increases due to decrease clearance and it also acts as nephrotoxic by unknown mechanism. On the other hand, ceftriaxone on its interaction with diclofenac for renal tubular clearance also increases the level of diclofenac and thus further aggravate the ischemia. It is a reversible condition with excluding diclofenac from the treatment regimen and giving adequate hydration to the patient. This highlights the importance of hydration and knowledge of drugs interactions in a postsurgical patient.

  17. Thrombotic microangiopathy with hypertension and acute renal failure in children (a typical hemolytic uremic syndrome.

    Full Text Available Thus I would like to conclude by saying that an idiopathic form of obliterative renal arteriopathy account for the rare presentation of severe hypertension and progressive renal failure with or without overt hemolytic anemia and thrombocytopenia in children. It can be labelled as primary malignant nephrosclerosis (NScl or atypical HUS, based on primary thrombotic angiopathy. This, essentially intimal changes, is seen in diverse conditions and appears to result from primary endothelial injury followed by intimal exudation, thrombosis, and repair by fibrosis. Persistent or recurrence of this process form the basis of progressive obliterative arteriopathy. The result is renal ischemia and renin-angiotensin mediated hypertension. Establishment of a vicious circle would further accelerate HT and lead to end stage renal failure. Early recognition and prompt therapeutic intervention might prove beneficial.

  18. Glutaric Aciduria type I and acute renal failure — Coincidence or causality?

    2014-01-01

    Full Text Available Glutaric Aciduria type I (GA-I is a rare organic acidemia, caused by mutations in the GCDH gene, and characterized by encephalopathic crises with neurological sequelae. We report herein a patient with GA-I who presented with severe acute renal failure requiring dialysis, following an acute diarrheal illness. Histopathological evaluation demonstrated acute tubular necrosis, and molecular diagnosis revealed the patient to be homozygous for a previously unreported mutation, p.E64D. As renal impairment is not part of the clinical spectrum typical to GA-I, possible associations of renal failure and the underlying inborn error of metabolism are discussed, including recent advancements made in the understanding of the renal transport of glutaric acid and its derivatives during metabolic disturbance in GA-I.

    Polypharmacy has become an emerging public health issue in recent years, since use of multiple medications or polypharmacy is beneficial for many conditions, but may also have negative effects like adverse drug reactions. The risk further increases in patients with chronic renal failure, a comorbidity very frequent in nursing home residents. Since more than 50% of all drugs were renally excreted, dose adjustments in patients with renal failure are required. To assess polypharmacy in German nursing homes, in particular in residents with renal failure. Multi-center cross-sectional study in 21 nursing homes in Bremen and Lower Saxony/Germany. Baseline data were analysed using descriptive statistics. Multivariable logistic regression model and 95% confidence intervals were used to study the association of renal failure and polypharmacy. Of all 852 residents, the analysis comprised those 685 with at least one serum creatinine value so that the estimated creatinine clearance could be calculated. Of those, 436 (63.6%) had a severe or moderate renal failure, defined as estimated creatinine clearance renal failure (estimated creatinine clearance renal failure are common in German nursing home residents and an association of both could be found. Further studies are needed to assess the appropriateness of polypharmacy in these patients.

  2. Capillary/myocyte mismatch in the heart in renal failure--a role for erythropoietin?

    Chronic renal failure is characterized by remodeling of the heart with left ventricular hypertrophy (increasing oxygen demand) and capillary deficit leading to capillary/myocyte mismatch (decreasing oxygen supply). Erythropoietin (Epo) has known angiogenic properties causing endothelial cell activation, migration and sprouting, mediated at least in part via the JAK/STAT (Janus kinase/signal transducers and activators of transcription) pathway. In uraemic cardiac hypertrophy the presence of diminished capillary supply implies that capillary growth does not keep pace with development of hypertrophy. To investigate whether this was due to a deficit of the angiogenic hormone Epo we examined whether Epo levels are altered and whether an increase in haematocrit by administration of rhEpo influences capillary supply, i.e. capillary/myocyte mismatch in experimental renal failure. Male Spraque-Dawley rats were either subjected to partial renal ablation or sham operation. Only modest amounts of renal tissue were removed so that the rats were not anemic. Subgroups of rats received either human (rh)Epo alone or in combination with unspecific antihypertensive treatment (dihydralazine plus furosemide) in order to control the Epo induced rise in blood pressure. Capillary supply was measured stereologically as capillary length per volume myocardium using the orientator method. Capillary length density was reduced by approximately 25% after partial renal ablation (3237+/-601 vs 4293+/-501 mm/mm(3) in controls). It was not statistically different in animals with partial renal ablation+rhEpo+antihypertensive treatment (3620+/-828 mm/mm(3)) compared to partial ablation alone. The study shows that lack of Epo does not cause, or contribute to, the deficit of capillary growth in the hypertrophied left ventricle of rats with renal failure. In addition, a rise in haematocrit is not accompanied by beneficial effects on alterations of cardiovascular structure in experimental renal failure.

    The application of laser photoacoustic spectroscopy (LPAS) for fast and precise measurements of breath biomarkers has opened up new promises for monitoring and diagnostics in recent years, especially because breath test is a non-invasive method, safe, rapid and acceptable to patients. Our study involved assessment of breath ethylene and breath ammonia levels in patients with renal failure receiving haemodialysis (HD) treatment. Breath samples from healthy subjects and from patients with renal failure were collected using chemically inert aluminized bags and were subsequently analyzed using the LPAS technique. We have found out that the composition of exhaled breath in patients with renal failure contains not only ethylene, but also ammonia and gives valuable information for determining efficacy and endpoint of HD. Analysis of ethylene and ammonia traces from the human breath may provide insight into severity of oxidative stress and metabolic disturbances and may ensure optimal therapy and prevention of pathology at patients on continuous HD.

    A 58-year-old man was admitted to our hospital. Laboratory data showed severe liver injury and that the patient was positive for immunoglobulin M anti-hepatitis A virus (HAV) antibodies. He was also complicated with severe renal dysfunction and had an extremely high level of serum hepatocyte growth factor (HGF). Therefore, he was diagnosed with severe acute liver failure with acute renal failure (ARF) caused by HAV infection. Prognosis was expected to be poor because of complications by ARF and high serum HGF. However, liver and renal functions both improved rapidly without intensive treatment, and he was subsequently discharged from our hospital on the 21(st) hospital day. Although complication with ARF and high levels of serum HGF are both important factors predicting poor prognosis in acute liver failure patients, the present case achieved a favorable outcome. Endogenous HGF might play an important role as a regenerative effector in injured livers and kidneys.

    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.

    We sought to determine from key clinical outcomes whether catheter ablation of atrial fibrillation (AF) is associated with increased survival. Using routinely collected hospital data, ablation patients were matched to two control cohorts using direct and propensity score methodology. Four thousand nine hundred ninety-one ablation patients were matched 1:1 with general AF controls without ablation. Five thousand four hundred seven ablation patients were similarly matched to controls who underwent cardioversion. We examined the rates of ischemic stroke or transient ischemic attack (stroke/TIA), heart failure hospitalization, and death. Matched populations had very similar comorbidity profiles, including nearly identical CHA 2 DS 2 -VASc risk distribution ( p =0.6948 and p =0.8152 vs general AF and cardioversion cohorts). Kaplan-Meier models showed increased survival after ablation for all outcomes compared with both control cohorts ( p vs general AF, p =0.0087 for stroke/TIA, p vs cardioversion). Cox regression models also showed improved survival after ablation for all outcomes compared with the general AF cohort (hazard ratio [HR]=0.4, 95% confidence interval [95% CI]: 0.3-0.6, p stroke/TIA; HR=0.4, 95% CI: 0.2-0.6, p stroke/TIA; HR=0.4, 95% CI: 0.3-0.6, p stroke/TIA, and heart failure compared with a matched general AF population and a matched population who underwent cardioversion. Potential confounding of outcomes was minimized by very tight cohort matching.

    Acute renal failure (ARF) is rarely an isolated process but is often a complication of underlying conditions such as sepsis, trauma, and multiple-organ failure in critically ill patients. As such, concomitant clinical conditions significantly affect patient outcome. Poor nutritional status is a major factor in increasing patients' morbidity and mortality. Malnutrition in ARF patients is caused by hypercatabolism and hypermetabolism that parallel the severity of illness. When dialytic intervention is indicated, continuous renal replacement therapy (CRRT) is a commonly used alternative to intermittent hemodialysis because it is well tolerated by hemodynamically unstable patients. This paper reviews the metabolic and nutritional alterations associated with ARF and provides recommendations regarding the nutritional, fluid, electrolyte, micronutrient, and acid-base management of these patients. The basic principles of CRRT are addressed, along with their nutritional implications in critically ill patients. A patient case is presented to illustrate the clinical application of topics covered within the paper.

    Knowledge of the characteristics and effective use of tumour markers for mesothelioma is essential for early-stage diagnosis of mesothelioma. We examined whether renal dysfunction influences blood concentrations of promising new tumour markers, N-ERC/mesothelin (N-ERC) and osteopontin (OPN), to an important degree. Levels of serum N-ERC and plasma OPN in 32 patients with chronic renal dysfunction, 22 of whom were on hemodialysis (CKD group), and 102 healthy volunteers were measured. Serum concentrations of N-ERC and plasma concentrations of OPN in the CKD group were significantly higher than those in volunteers, regardless of diabetes status and age. Blood concentrations of these markers increased as renal function decreased. N-ERC and OPN concentrations are significantly influenced by renal function. Therefore, the extent of renal failure must be considered when inferring the existence of tumours and chemotherapeutic response from the values of these markers in routine practice.

    Neutrophil Gelatinase-associated Lipocalin (NGAL) protein is easily detected in the blood and urine soon after acute renal injury. NGAL gains features of an early, sensitive and noninvasive biomarker for acute renal injury. Recent evidences suggest that its expression is also increased in CRF reflecting the severity of disease. In the present study, we aimed to investigate whether blood NGAL level plays a role in the differential diagnosis of acute and chronic renal failure. This was a prospective case-control study. Fifty patients presented to emergency department with acute renal failure (ARF), 30 with chronic renal failure (CRF) and 20 healthy individuals as control group were included in this study. Blood pH, HCO3(-), BUN, creatinine and potassium values were evaluated in all patients. Blood NGAL values were evaluated in all groups. BUN, serum creatinine and NGAL values were statistically compared between patients and controls. Median NGAL levels in patients was 304.50 (29), and 60 (0) in control, which was statistically significant between the two groups (Z = -6.477, P 0.05). Median creatinine values were 2.84 ± 2.95 in ARF group and 4.78 ± 4.32 in CRF group. In serum creatinine values, a significant difference was found between ARF and CRF groups (P renal injury and differentiate ARF and CRF.

    To analyze the treatment of acute renal failure caused by irrational drug use. Data of 41 cases of acute renal failure seen from July 2008 to June 2012 in our hospital were reviewed. Bilateral renal parenchymas diffuse echo was found enhanced by ultrasound in all cases. Calculus image was not found by X-ray. All children had medical history of using cephalosporins or others. Alkalinization of urine and antispasmodic treatment were given to all children immediately, 17 children were treated with hemodialysis and 4 children accepted intraureteral cannula placement. In 24 children who accepted alkalinization of urine and antispasmodic treatment micturition could be restored within 24 hours, in 11 children micturition recovered after only one hemodialysis treatment and 2 children gradually restored micturition after hemodialysis twice, 4 children who accepted intraureteral cannula immediately restored micturition. In all children micturition recovered gradually after a week of treatment. Ultrasound examination showed that 39 children's calculus disappeared totally and renal parenchymas echo recovered to normal. The residual calculi with diameter less than 5 mm were found in 2 children, but they had no symptoms. The children received potassium sodium hydrogen citrate granules per os and were discharged from hospital. Ultrasound showed calculus disappeared totally one month later. Irrational drug use can cause children urolithiasis combined with acute renal failure, while renal dysfunction can reverse by drug withdrawal and early alkalinization of urine, antispasmodic treatment, intraureteral cannula or hemodialysis when necessary, most calculus can be expelled after micturition recovered to normal.

    To assess differences in clinical outcomes of isolated renal failure (RF) compared to other forms of organ failure (OF) in patients with severe acute pancreatitis (SAP). Using a prospectively maintained database of patients with acute pancreatitis admitted to a tertiary medical center between 2003 and 2016, those with evidence of persistent OF were classified to renal, respiratory, cardiovascular, or multi-organ (2 or more organs). Data regarding demographics, comorbidities, etiology of acute pancreatitis, and clinical outcomes were prospectively recorded. Differences in clinical outcomes after development of isolated RF in comparison to other forms of OF were determined using independent t and Mann-Whitney U tests for continues variables, and χ 2 test for discrete variables. Among 500 patients with acute pancreatitis, 111 patients developed persistent OF: mean age was 54 years, and 75 (67.6%) were male. Forty-three patients had isolated OF: 17 (15.3%) renal, 25 (21.6%) respiratory, and 1 (0.9%) patient with cardiovascular failure. No differences in demographics, etiology of acute pancreatitis, systemic inflammatory response syndrome scores, or development of pancreatic necrosis were seen between patients with isolated RF vs isolated respiratory failure. Patients with isolated RF were less likely to require nutritional support (76.5% vs 96%, P = 0.001), ICU admission (58.8% vs 100%, P = 0.001), and had shorter mean ICU stay (2.4 d vs 15.7 d, P failure. None of the patients with isolated RF or isolated respiratory failure died. Among patients with SAP per the Revised Atlanta Classification, approximately 15% develop isolated RF. This subgroup seems to have a less protracted clinical course compared to other forms of OF. Isolated RF might be weighed less than isolated respiratory failure in risk predictive modeling of acute pancreatitis.

    Full Text Available The aim was to study prevalence of some risk factors of the renal dysfunction. Methods and results. 344 patients with ischemic chronic heart failure were included. Clinical, medical history, laboratory and instrumental data were analyzed. It was established that renal dysfunction is accompanied by traditional (age, hyperlipidemia, hypertension, myocardial infarction, obesity, left ventricular hypertrophy and non-traditional risk factors (hyperuricemia, atrial fibrillation, left ventricular ejection fraction, left atrial volume index, cystatin C whose role increases with a decrease in glomerular filtration rate. Conclusion. This shows the close relationship between traditional and non-traditional risk factors that contribute to the development of cardio-renal complications.

    A 45-year-old woman was admitted to our hospital because of high fever and malaise. She also presented abnormal urine findings including macrohematuria and proteinuria with transient renal insufficiency. Salmonella Typhi was isolated from her blood and stool culture, and then she was diagnosed as having typhoid fever. Salmonella enterica serotype typhi infection can be complicated by renal involvement, although rare. In Japan, few cases have been reported about acute nephritic syndrome in typhoid fever. Here, we report a case of endemic acquired typhoid fever associated with acute renal failure probably due to acute nephritic syndrome successfully treated with levofloxacin.

    Full Text Available Penile gangrene associated with chronic renal failure is very uncommon. A 52-year-old man with diabetes mellitus, diffuse atherosclerosis, ischemic cardiomyopathy and end-stage renal disease presented with blackening of distal penis for 10 days. His general condition was poor and gangrene of prepuce and glans was noted. Doppler and magnetic-resonance angiography revealed bilateral internal iliac artery obstruction. He underwent trocar suprapubic cystostomy and was planned for partial penectomy. But he died of severe diabetic complications in the interim period. Penile gangrene is a manifestation of widespread vascular calcifications associated with end-stage renal disease and is a marker of poor prognosis.

    One-quarter of deaths in children with chronic renal failure is due to cardiovascular complications. Conventional echocardiographic methods are insufficient for evaluating systolic functions in children with chronic renal failure. The aim of the present study was to investigate cardiac functions in children with chronic renal failure by evaluating left atrial volume and functions. The present cross-sectional observational study included 44 children undergoing dialysis, 16 children with chronic renal failure but not yet on dialysis, and 20 healthy control subjects. Transthoracic echocardiography was performed for all children. Variables regarding to left ventricle and atrium (left atrial systolic force, left atrial systolic force index, left atrial volume, left ventricular mass index, and relative wall thickness) were measured using two-dimensional and M-mode echocardiography. Left atrial systolic force index was negatively correlated with systolic blood pressure and left ventricular mass (p=0.01, r=0.266 and p=0.02, r=0.347, respectively). However, it was positively correlated with both early and late diastolic mitral inflow velocity (r=0.518, p=0.001 and r=0.828, p=0.001, respectively). There were no significant difference among the groups in terms of left atrial systolic force index and left atrial volume. However, left atrial systolic force index was higher in children with chronic renal failure but not yet on dialysis. Left atrial systolic force was negatively correlated with systolic blood pressure and left ventricular mass. These findings suggested that evaluating left atrial systolic force and left atrial volume were useful to determine diastolic dysfunction and the necessity of dialysis in patient with chronic renal failure.

    Loss of bone mineral of the skeleton in renal disease can be measured directly by total body neutron activation analysis (TBNAA), and also by an absorptiometric technique applied to the appendicular skeleton (radius). In the present study the results of these two techniques are compared in 25 patients with renal insufficiency, 53 patients with end-stage renal failure on dialysis, and 24 normal control subjects. It is apparent that there is good correlation between total body calcium (TBCa) and bone mineral content (BMC) in all groups studied. The correlation in the normal contrast group was 0.944 as compared to 0.919 for the renal patients and 0.892 for patients with end-stage renal failure on dialysis. In order to measure the relative deficit in TBCa in individual patients from the absolute Ca measurement, it is necessary to normalize the data for sex, age, and skeletal size. For this purpose, an empirically derived relationship was used to predict the normal skeletal Ca in each subject, based on weight, height, sex, and age. The measured TBCa divided by the predicted TBCa is referred to as the calcium ratio. This ratio is useful in expressing the relative deficit of Ca in individual renal patients. In similar manner, BMC data were normalized, with the same relationship used to obtain BMC ratios. The normalization procedures allow both the TBCa and BMC measurements to be used to quantitate the Ca deficit in individual patients with renal insufficiency

    Chronic renal failure is a type of clinical syndrome originating from chronic renal diseases. The aim of the study was to investigate the effect of astrogaloside on the inflammation and immunity of renal failure patients receiving maintenance dialysis. We randomly selected 92 renal failure patients receiving maintenance dialysis who were admitted to hospital for treatment between May, 2015 and April, 2016. Patients were randomly divided into the control (n=46) and observation (n=46) groups. Patients in the control group received the regular dialysis plus the basic treatment in Western medicine, while in the observation group, patients additionally received astrogaloside via intravenous injection as treatment. We compared the clinical efficacy of patients between the two groups, residual renal function (RRF), changes in urine volume, variations in inflammatory indicators [C-reaction protein (CRP), interleukin-6 (IL-6), IL-17, and tumor necrosis factor-α (TNF-α)] before and after treatment, and the levels of the thymus-dependent lymphocyte (T cells) subgroup (CD3 + , CD4 + , CD8 + and CD4 + /CD8 + ) in the immune system of patients after treatment. In the observation group, the total effective rate was significantly higher than that in the control group (Prenal failure patients receiving the maintenance dialysis, ameliorate the inflammatory responses, and enhance the immune function, thereby increasing the disease resistance of patients and improving the clinical symptoms.

  2. Interaction of prostaglandins and angiotensin II in the modulation of renal function in congestive heart failure.

    1988-06-01

    Despite a dramatic fall in renal blood flow, glomerular filtration rate is usually preserved in patients with congestive heart failure until the terminal stages of the disease. This maintenance of renal function appears to be achieved in part by the synthesis of two vasoactive factors within the kidney--angiotensin II and prostaglandins--which are rapidly released whenever renal perfusion is compromised or sympathetic nerve traffic to the kidneys is increased. Although these two hormonal systems exert opposite effects on systemic and renal blood flow and sodium and water excretion, both act to preserve glomerular filtration rate: prostaglandins by a vasodilator action exerted primarily on the afferent arteriole and angiotensin II by a vasoconstrictor effect on the efferent arteriole. Consequently, when the synthesis of these hormones is experimentally blocked, renal function deteriorates, especially in subjects with marked renal hypoperfusion and sodium depletion; these two factors interact to determine the importance of intrarenal hormonal release in the modulation of renal function. Clinically, four specific factors have been identified that predispose patients with heart failure to the development of functional renal insufficiency after treatment with converting-enzyme or cyclo-oxygenase inhibitors: (1) marked renal hypoperfusion, (2) vigorous diuretic therapy, (3) diabetes mellitus, and (4) intensity of hormonal inhibition within the kidney. This last risk factor may provide the basis for differentiating among enzyme-inhibitory drugs and suggests that renal insufficiency in low-output states may be minimized by the development of therapeutic agents that block hormonal synthesis selectively at sites that are critical to the disease process but spare the homeostatic tissue-based enzyme systems that exist within the kidney.

    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.

    In recent years there has been a large increase in the areas related to developments in the prevention of diseases, especially in explaining the role of oxidative stress. Lipid peroxidation and oxidative stress contributes to morbidity in hemodialysis (HD) patients. It is therefore relevant to analyze the impact of oxidative stress and its related species (ethylene) immediately after dialysis treatment in order to prevent trauma in the renal failure of elderly patients. In this paper we describe recent progress in laser photoacoustic spectroscopy detection of ethylene in renal failure patients. We have found that HD treatment increases ethylene concentration in the exhaled breath of elderly patients and may intensify oxidative stress.

    93 cases of kidneys which had been found to be not functioning in the excretion urography were examined with regard to the correctness of the angiographic diagnosis. We conclude from the results that in case of a renal failure in patients with a satisfactory general condition, renal arteriography is the method to be chosen to recognize the causes of the failure. Furthermore, preexaminations are necessary for the surgical elimination of the clinical symptoms; here, renovasography is definitely the most efficient examination method. (orig./MG) [de

    Technetium-99m pyrophosphate (Tc-PYP) imaging was performed in five patients with acute renal failure associated with nontraumatic rhabdomyolysis. Four patients had phencyclidine intoxication and one had viral pneumonia. During the acute phase, marked uptake of pyrophosphate was seen in all patients in several muscle groups, but always in the thigh adductors. The results show that phencyclidine intoxication can result in diffuse muscle uptake of Tc-PYP without overt evidence of muscle injury. Tc-PYP imaging may provide a clue to the cause of acute renal failure in patients with suspected rhabdomyolysis in whom elevations of serum creatine phosphokinase concentrations are equivocal.

    Serum carbamylated albumin (C-Alb) levels are associated with excess mortality in patients with diabetic end-stage renal disease. To gain insight into the pathophysiology of carbamylation, we determined associations between C-Alb and causes of death in patients on chronic hemodialysis. The Die Deutsche Diabetes Dialyse Studie (4D study) was a randomized controlled trial testing the effects of atorvastatin on survival in diabetic patients on dialysis during a median follow-up of 4 years. We stratified 1161 patients by C-Alb to see whether differences in carbamylation altered the effects of atorvastatin on survival. Baseline C-Alb significantly correlated with serum cardiac stress markers troponin T and N-terminal pro-B-type-natriuretic peptide and was associated with a history of heart failure and arrhythmia. C-Alb was strongly associated with 1-year adjusted risk of cardiovascular mortality, sudden cardiac death, and the 4-year risk of death from congestive heart failure (hazard ratios of 3.06, 3.78, and 4.64, respectively) but not with myocardial infarction or stroke. Patients with low C-Alb, treated with atorvastatin, experienced a significant improvement in their 4-year survival (hazard ratio 0.692). High C-Alb levels are associated with ongoing cardiac damage, risk of congestive heart failure, and sudden cardiac death. Thus, carbamylation and uremic cardiomyopathy are associated in patients with diabetes mellitus and kidney disease. In addition, statins were specifically beneficial to hemodialysis patients with low C-Alb.

    Diabetic kidney disease (DKD) has become the leading cause of end-stage renal disease. Recent studies demonstrate that in a significant part of diabetic patients the renal insufficiency is frequently caused by non-diabetic kidney diseases, so that an effective clarification of untypical clinical courses is mandatory. Important cornerstones of DKD therapy are an optimized glycaemic management as well as a good blood pressure control. Although the prognosis of DKD has been improved in the last years, it is, even with novel therapy approaches, not possible to prevent the development of DKD. It remains to hope that with extended knowledge, intensified preclinical studies and well-defined clinical trials novel nephroprotective therapies become available in the next years.

    Recent reports have raised concerns regarding renal outcomes in patients with decompensated acute heart failure (HF) treated with slow continuous ultrafiltration (SCUF). The purpose of this study was to identify risk factors for renal failure (RF) requiring dialysis in patients with acute HF initiated on SCUF. We studied 63 consecutive patients with acute HF who required SCUF because of congestion refractory to hemodynamically guided intensive medical therapy. Median serum creatinine at SCUF initiation was higher in patients who developed RF requiring dialysis [2.5 (interquartile range 1.8-3.3) vs 1.6 (1.2-2.3) mg/dL; P acute HF initiated on SCUF, onset of RF requiring dialysis is associated with high mortality. Systolic perfusion pressure which incorporates both perfusion and venous congestion parameters may present a modifiable risk factor for worsening RF during SCUF in acute HF patients.

    Circulating levels of bone-derived fibroblast growth factor 23 (FGF23) increase early during acute and chronic kidney disease and are associated with adverse outcomes. Membrane-bound Klotho acts as a permissive coreceptor for FGF23, and its expression was recently found in osteoblasts/osteocytes. We hypothesized that Klotho in bone cells is part of an autocrine feedback loop that regulates FGF23 expression during renal failure. Thus, we induced renal failure in mice with targeted deletion of Klotho in long bones. Uremic wild-type ( KL fl/fl ) and knockout ( Prx1-Cre;KL fl/fl ) mice both responded with reduced body weight, kidney atrophy, hyperphosphatemia, and increased bone turnover. Importantly, long bones of Prx1-Cre;KL fl/fl mice but not their axial skeleton failed to increase FGF23 expression as observed in uremic KL fl/fl mice. Consequently, Prx1-Cre;KL fl/fl mice had significantly lower serum FGF23 and parathyroid hormone levels, and higher renal 1-α-hydroxylase expression, serum 1,25-dihydroxyvitamin D, and calcium levels than KL fl/fl mice. These results were confirmed in two independent models of renal failure, adenine diet induced and 5/6 nephrectomy. Moreover, FGF23-treated bone cells required Klotho to increase FGF23 mRNA and ERK phosphorylation. In summary, our novel findings show that Klotho in bone is crucial for inducing FGF23 production upon renal failure. We propose the presence of an autocrine feedback loop in which Klotho senses the need for FGF23.-Kaludjerovic, J., Komaba, H., Sato, T., Erben, R. G., Baron, R., Olauson, H., Larsson, T.

    This is a report on a patient of 64 years of age who was admitted to hospital as an inpatient thirteen years after desobliteration of the iliac artery with an extension plasty. He complained of irregular stools and occasional abdominal pain. Imaging methods were employed on account of a drop in the haemoglobin count, progressive renal insufficiency and a palpable tumor in the lower abdomen. These methods supplied evidence of a false aneurysm originating from the iliacal endarterectomy, combined with compression of the ureter and small intestine. Basing on the present case report, the general complex of problems in diagnosing aneurysms of the iliac artery is discussed. (orig.) [de

    Renal dynamic CT scanning is suitable for determining the excretion of contrast medium in the cortex and medulla of the kidney, which is valuable for understanding the pathogenesis of disease processes in various conditions. This form of scanning would be convenient for use, if a method of application to the rat kidney were available. Therefore, we developed a method of applying renal dynamic CT to rats and evaluated the cortical and medullary curves, e.g., the corticomedullary junction time which is correlated to creatinine clearance, in various rat models of acute renal failure. The rat was placed in a 10deg oblique position and a bilateral hilar slice was obtained before and 5, 10, 15, 20, 25, 30, 40, 50, 60, 80, 100, 120, 140, 160 and 180 sec after administering 0.5 ml of contrast medium using Somatom DR. The width of the slice was 4 mm and the scan time was 3 sec. The corticomedullary junction time in normal rats was 23.0±10.5 sec, the peak value of the cortical curve was 286.3±76.7 Hounsfield Unit (HU) and the peak value of the medullary curve was 390.1±66.2 HU. Corticomedullary junction time after exposure of the kidney was prolonged compared to that of the unexposed kidney. In rats with acute renal failure, the excretion pattern of contrast medium was similar in both the glycerol- and HgCl2-induced acute renal failure models. The peak values of the cortical curve were maintained three hours after a clamp was placed at the hilar region of the kidney for one hour, and the peak values of the medullary curve were maintained during the administration of 10μg/kg/min of angiotensin II. Dynamic CT curves in the acute renal failure models examined were slightly different from those in human acute renal failure. These results suggest that rats do not provide an ideal model for human acute renal failure. However, the application of dynamic CT to the rat kidney models was valuable for estimating the pathogenesis of various human kidney diseases. (author)

    2003-01-01

    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. The aim of the present...... 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...... potassium concentrations at day 90 and patients in the low group experienced a slight increase in GFR. CONCLUSIONS: In moderate to severe chronic renal insufficiency the same degree of blood pressure control was achieved on low as well as moderate daily doses of enalapril. This was irrespective...

  10. Current Concepts on Diabetic Nephropathy and 2014 Data on Diabetic Renal Failure in Texas.

    2016-07-01

    Diabetic nephropathy (DN) is the leading cause of end-stage renal disease (ESRD) in the United States and other developed countries. In 1982, diabetes accounted for 27% of patients with ESRD in the United States and rose to 36% by 1992 and to 47% in 2012. Currently, the number of prevalent cases of ESRD in the country (dialysis and transplant) exceeds more than 636,900. Primary care practitioners (PCP) provide more than 90% of the diabetic care and are well-positioned to identify, prevent, and treat initially DN. PCPs should identify DN with a urine microalbumin test, obtain a serum creatinine and glomerular filtration rate, monitor hemoglobin A1c, and treat hypertension and dyslipidemia according to current guidelines. This article reviews basic concepts and goals for DN as well as the 2014 data for diabetic renal failure in the most populous counties in Texas. The Texas counties bordering Mexico show an excessive prevalence of diabetic renal failure.

    Dengue is an emerging, rapidly expanding disease, whose clinical and biological manifestations vary. Kidney injury is not usual but can be severe, and it is most often associated with dengue hemorrhagic fever or shock. Guadeloupe, which is located in an endemic area, experienced an epidemic from 2013 to 2014. During this outbreak, a case of renal failure during dengue was observed in a 10-year-old child. No evidence of dengue hemorrhagic fever or shock syndrome was found. The clinical and biological course improved with symptomatic treatment. The association of acute renal failure with hemolytic anemia suggested a diagnosis of hemolytic uremic syndrome. However, this could not be confirmed in the absence of thrombocytopenia and cytopathologic evidence. This case illustrates the diversity of clinical presentations of dengue, and the possibility of severe renal impairment unrelated to the usual factors encountered in dengue.

    Jud, Philipp; Gary, Thomas; Tiesenhausen, Kurt; Portugaller, Rupert; Hackl, Gerald; Brodmann, Marianne

    2017-01-01

    Abstract Rationale: Abdominal aortic aneurysms (AAAs) are mostly asymptomatic. If aortic aneurysms become symptomatic, complications include peripheral embolization, acute aortic occlusion, and aortic rupture. However, there are also unusual complications caused by aortic aneurysms. Patient concerns: An 87-old male with dabigatran therapy presented with newly developed melena and acute renal failure. Radiological imaging revealed an AAA with thrombotic and calcified deposits which affected the renal arteries. Diagnoses: Gastrointestinal bleeding and hypercoagulation caused by renal failure which was triggered in turn due to an AAA. Interventions: Adapted antihypertensive therapy and initiation of simvastatin 40mg once daily as well as antiplatelet therapy with aspirin 50 mg once daily due to patient's refusal of any aneurysm intervention. Outcome: Neither bleeding event nor aneurysm rupture occurred with the adapted antihypertensive therapy, simvastatin and aspirin. Lessons: Nonruptured AAAs can cause rare, unusual, and even life-threatening complications depending on their size and anatomical position. PMID:28445318

    The purpose of this study is to evaluate whether there is any correlation between the CT features of hemosiderosis and clinical findings in patients with chronic renal failure who have received multiple blood transfusion. Among chronic renal failure patients who had undergone long-tern dialysis and received multiple blood transfusions, CT findings in 16 cases in which increased liver attenuation was seen on images obtained for other purpose, were analyzed by three radiologic specialists. The attenuation values of liver, spleen and pancreas compared with that of back muscle were correlated with the amount and duration of transfusion, and blood ferritin level. There is no correlation between the CT features of hemosiderosis and clinical findings. In patients with chronic renal failure and no clinical symptoms, the status of iron overload was relatively easily detected on CT. Close observation of CT findings is thus thought to prevent significant permanent functional deformity of organs in patients with chronic renal failure who have received multiple blood transfusions.

    Calcitriol is a standard therapy for secondary hyperparathyroidism in chronic renal failure. We evaluated whether the effect of daily or intermittent calcitriol administration is more efficient in enhancing bone growth in renal failure with advanced secondary hyperparathyroidism in weanling 5/6 nephrectomized rats loaded with phosphorus to induce severe secondary hyperparathyroidism. The animals were treated daily or three times weekly with calcitriol for 4 weeks but the total weekly dose of calcitriol was the same. Although calcitriol increased the serum calcium, it did not lower parathyroid hormone (PTH) or improve tibia and body length. Animals with renal failure and advanced secondary hyperparathyroidism had decreased PTH/PTHrP, which was accompanied by an increase in the cyclin kinase inhibitor p57(Kip2). Calcitriol treatment upregulated the PTH/PTHrP receptor but also increased inhibitors of cell proliferation such as p21(Waf1/Cip1), IGFBP3, and FGFR3. Calcitriol also enhanced markers of chondrocyte differentiation, such as IGF1, Vitamin D receptor, FGF23, and bone morphogenetic protein-7. Receptor activator of nuclear factor-kappabeta ligand levels improved with calcitriol treatment but without changes in osteoprotegerin suggesting an enhancement of osteo/chondroclastogenesis and mineralization. Overall, both daily and intermittent calcitriol had similar effects on endochondral bone growth in phosphorus-loaded rats with renal failure.

    Rapid advancements have been made in alternative treatments for renal diseases. Our goal for renal regeneration is to establish a kidney graft derived from human embryonic tissues. In this study, we investigated the effects of host renal failure on the structure and activity of transplanted embryonic kidney and bladder, and found that diuretics effectively induced urine production in the transplanted kidney. Uremic conditions were reproduced using a 5/6 renal infarction rat model. An embryonic kidney plus bladder (embryonic day 15) was isolated from a pregnant Lewis rat and transplanted into the para-aortic area of a 5/6 renal-infarcted Lewis rat. Following growth, the embryonic bladder was successfully anastomosed to the host ureter. We assessed graft function in terms of survival rates and found no differences between normal (n = 5) and renal failure (n = 8) groups (median survival: 70.5 vs 74.5 h; p = 0.331) in terms of survival, indicating that the grafts prolonged rat survival, even under renal failure conditions. Furosemide (n = 9) significantly increased urine volume compared with saline-treated controls (n = 7; p < 0.05), confirming that the grafts were functional. We also demonstrated the possibilities of an in vivo imaging system for determining the viability of transplanted embryonic kidney with bladder. The results of this study demonstrate that transplanted embryonic kidney and bladder can grow and function effectively, even under uremic conditions.

    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

To determine whether the inferior vena cava (IVC measurement by bedside ultrasound (US-IVC predicts improvement in renal function in patients with acute kidney injury (AKI. Design. Prospective observational study. Setting. Medical intensive care unit. Patients. 33 patients with AKI were included. Intervention. US-IVC was done on admission. The patients’ management was done by the primary teams, who were unaware of the US-IVC findings. Two groups of patients were identified. Group 1 included patients who were managed in concordance with their US-IVC (potential volume responders who had a positive fluid balance at 48 h after admission and potential volume nonresponders who had an even or negative fluid balance at 48 hours after admission. Group 2 included patients in whom the fluid management was discordant with their US-IVC. Measurements and Main Results. At 48 hours, Group 1 patients had a greater improvement in creatinine [85% versus 31%, p=0.0002], creatinine clearance (78±93% versus 8±64%, p=0.002, and urine output (0.86±0.54 versus 0.45±0.36 ml/Kg/h, p=0.03. Conclusion. In critically ill patients with AKI, concurrence of fluid therapy with IVC predicted fluid management, as assessed by bedside ultrasound, was associated with improved renal function at 48 hours.

    To determine the incidence and risk factors of acute renal failure (ARF) in hospitalized critically ill neonates and analyze outcome of all neonates with renal failure in relation to risk factors. In this prospective observational study 815 infants were enrolled. Renal profile (blood urea and serum creatinine) was done after 12 h of life (or at the time of admission for outborn babies) and then every 12 hourly. Daily 24 h urine output was evaluated. Incidence of renal failure in critically ill neonates was 10.67%. Out of 87 ARF neonates 52 (60%) expired. Mortality in the renal failure group was significantly higher in comparison to control group (p renal failure was more common than oliguric renal failure, but mortality in the oliguric renal failure group was more. Neonatal sepsis was the most common cause of ARF. Eight neonates underwent peritoneal dialysis (PD) out of which there were seven neonatal deaths. Prognosis of neonates with ARF requiring PD was very poor. It can thus be concluded that the health care personal should do rapid diagnosis of ARF in neonates with potential risk factors and also goal at an early and effective treatment of these risk factors in neonates with ARF.

    The renal effects of whole body irradiation in the perinatal period were studied in the dog. Ninety-three dogs received a single sublethal exposure in the range of 270 to 435 R in either late gestation (55 days postcoitus) or early postnatal life (2 days postpartum) and were sacrificed at 70 days, 2, or 4 years of age. Early renal lesions in 70-day-old irradiated dogs were characterized by arrested glomerular maturation and degeneration resulting in reduced functional renal mass. Mature glomeruli exhibited mesangial proliferation. At 2 and 4 years of age, surviving irradiated dogs exhibited sever renal disease associated with progressive glomerular damage which was characterized by mesangial proliferation and compression of capillary lumina, epithelial degeneration and focal capsular adhesions, and ultimately obliterative glomerulosclerosis. Twenty-one of the 93 irradiated dogs died in renal failure before 4 years of age with advanced glomerulosclerosis. The phatogenesis of this progressive renal lesion may be related to the interaction of three specific factors. These include (1) the effect of direct radiation damage to mature kidney components; (2) the loss of outer cortical nephrons resulting in increased work load of the surviving nephrons; and (3) the effect of compensatory hypertrophy related to the loss of renal parenchyma as the rapid growth rates associated with kidney maturation

    Management of diabetic retinopathy should follow more strict and aggressive rules in patients at risk for severe acute renal impairment. Such patients should be identified and possibly prophylactically laser treated to avoid the severe consequences demonstrated in this case report. A 34-year-old type 2 diabetes patient with a stabilized diabetic retinopathy developed acute and severe retinal decompensation within weeks after acute renal failure complicated his chronic stable renal impairment. Fluorescein angiographic and optical coherence tomographic illustrations of the rapid evolution of the retinal condition are presented. The patient had previously been treated with panretinal photocoagulation in his left eye. After 8 years of regular 6-monthly checked stability, he developed rapid-onset proliferative diabetic retinopathy and macular edema in his right eye within 3 months of his last ocular check-up. Fluorescein angiography showed neovessels and major ischemic areas. Emergency panretinal photocoagulation and a sub-Tenon's injection were necessary to achieve control of the situation with regression of neovessels and complete regression of macular edema. This case shows that it is imperative for nephrologists to be well informed about a patient's ocular situation in order to give timely information to the ophthalmologist who can intervene to protect the retina in case of renal failure. On the other hand, the ophthalmologist should be familiar with the renal function of his patient with renal impairment so that he can decide to perform prophylactic retinal panphotocoagulation that should be imperatively considered even without strict indications in patients with renal impairment at risk for further deterioration of renal function, in order to prevent such explosive ischemic and proliferative retinopathy putting vision at risk.

    Full Text Available 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.

    Mitral regurgitation (MR) is a frequent valve disorder in elderly patients, often accompanied by multiple comorbidities such as renal impairment. In these patients percutaneous mitral valve (MV) repair has become an established treatment option but the role of MR on renal dysfunction is not yet well defined. We here report on two cases presenting with severe MR and progressive renal failure caused by cardio renal syndrome, in which percutaneous MV treatment with the MitraClip system significantly improved renal function. These findings suggest that interventional MV repair can prevent progression of renal deterioration in patients suffering from combined advanced heart and renal failure. Further clinical studies are necessary to support our finding and to answer the question whether optimizing renal function by implantation of the MitraClip device is also of prognostic relevance in these patients. © 2014 Wiley Periodicals, Inc.

    Tetracyclines are broad-spectrum antibiotics used by dental practitioners in the treatment of periodontal disease. They generally are safe in adults. However, caution is advised in patients who have pre-existing kidney disease. A 42-year-old woman with polycystic kidney disease received a prescription for tetracycline (250 milligrams, four times daily) after undergoing tooth extractions. She developed nausea, vomiting and diarrhea within days and end-stage renal disease within two weeks of taking the antibiotic. Hemodialysis was required to stabilize the patient's condition. Use of the Naranjo nomogram demonstrated an association between the two events. This case illustrates the importance of obtaining a thorough medical history and understanding potential adverse drug effects before prescribing a common antibiotic.

    Full Text Available A homocisteína é um aminoácido sulfurado proveniente do metabolismo da metionina, cujo acúmulo anormal no plasma é um fator de risco para doenças vasculares, tanto na população em geral como nos pacientes com insuficiência renal crônica. 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

    Urinary calprotectin has recently been identified as a promising biomarker for the differentiation between prerenal and intrinsic acute kidney injury (AKI) in the nontransplant population. The present study investigates whether calprotectin is able to differentiate between these 2 entities in transplant recipients as well. Urinary calprotectin was assessed by enzyme-linked immunosorbent assay in 328 subjects including 125 cases of intrinsic acute allograft failure, 27 prerenal graft failures, 118 patients with stable graft function, and 58 healthy controls. Acute graft failure was defined as AKI stages 1 to 3 (Acute Kidney Injury Network criteria), exclusion criteria were obstructive uropathy, urothelial carcinoma, and metastatic cancer. The clinical differentiation of prerenal and intrinsic graft failure was performed either by biopsy or by a clinical algorithm including response to fluid repletion, history, physical examination, and urine dipstick examination. Reasons for intrinsic graft failure comprised rejection, acute tubular necrosis, urinary tract infection/pyelonephritis, viral nephritis, and interstitial nephritis. Calprotectin concentrations of patients with stable graft function (50.4 ng/mL) were comparable to healthy controls (54.8 ng/mL, P = 0.70) and prerenal graft failure (53.8 ng/mL, P = 0.62). Median urinary calprotectin was 36 times higher in intrinsic AKI (1955 ng/mL) than in prerenal AKI (P renal allograft biopsy specimens confirmed the serological results. Urinary calprotectin is a promising biomarker for the differentiation of prerenal and intrinsic acute renal allograft failure.

    frequent complications of hemodialysis treatments are coagulation disorders. This is due to activation of the coagulation of blood flow in the interaction with a dialysis membrane material vascular prostheses and extracorporeal circuit trunks. In addition, in hemodialysis patients receiving heparin for years, there is depletion of stocks in endothelial cells in tissue factor inhibitor, inhibits the activity of an external blood clotting mechanism. the aim of our study was to evaluate the hemostatic system parameters in patients with end-stage renal failure, depending on the cause of renal failure. to evaluate the hemostatic system parameters in patients with end-stage renal failure, depending on the cause of renal failure and hemodialysis treatment duration conducted a study that included 100 patients observed in the department of chronic hemodialysis and nephrology hospital №1 Republican National Medical Center in the period of 2013-2016. in patients with end-stage renal failure in the outcome of chronic glomerulonephritis, a great expression of activation of blood coagulation confirm increased the mean concentration of fibrinogen, whereas in the group, which included patients with end-stage renal failure in the outcome of other diseases, such is not different from the norm, and a higher rate of hyperfibrinogenemia, identified in 2/3 patients in this group. it was revealed that the state of homeostasis in patients with end-stage renal failure in increasingly characterizes the level of fibrinogen and the activation of the hemostatic markers: soluble fibrin monomer complexes, D-dimers.

    A 69-year-old female was receiving renal replacement therapy (RRT) for acute renal failure (ARF) in an intensive care unit (ICU). Consultation was requested from the palliative medicine service to facilitate a shared decision-making process regarding goals of care. Clinician responsibility in shared decision making includes the formulation and expression of a prognostic assessment providing the necessary perspective for a spokesperson to match patient values with treatment options. For this patient, ARF requiring RRT in the ICU was used as a focal point for preparing a prognostic assessment. A prognostic assessment should include the outcomes of most importance to a discussion of goals of care: mortality risk and survivor functional status, in this case including renal recovery. A systematic review of the literature was conducted to document published data regarding these outcomes for adult patients receiving RRT for ARF in the ICU. Forty-one studies met the inclusion criteria. The combined mean values for short-term mortality, long-term mortality, renal-function recovery of short-term survivors, and renal-function recovery of long-term survivors were 51.7%, 68.6%, 82.0%, and 88.4%, respectively. This case example illustrates a process for formulating and expressing a prognostic assessment for an ICU patient requiring RRT for ARF. Data from the literature review provide baseline information that requires adjustment to reflect specific patient circumstances. The nature of the acute primary process, comorbidities, and severity of illness are key modifiers. Finally, the prognostic assessment is expressed during a family meeting using recommended principles of communication.

    Computed tomography using X-ray (XCT) and single photon emission computed tomography (SPECT) using sup(99m)Tc-MDP of the skull were performed in patients with ''senile osteoporosis'' and with chronic renal failure, in order to quantitatively determine bone mineral contents. XCT: In females with postmenopausal osteoporosis (6th decade), the EMI number of frontal bone was significantly low compared with that of control group, of the same age. The EMI number in ''senile osteoporosis'' correlated with the value of serum 25 (OH) D and 1 α - 25 (OH) 2 D. The EMI number in hemodialyzed patients was significantly low compared with that in the control group. On the other hand, the EMI number in non-hemodialyzed chronic renal failure patients showed no significant difference compared with findings in the control group. The EMI number of the frontal bone in patients with partial parathyroidectomy showed a slight rise compared with findings before surgery. Bone scintigram, Bone scan SPECT: Positive scan was seen in patients with long term hemodialysis and increased values of serum Alk-Pase and PTH were often apparent. Scintigraphic improvement in patients with renal osteodystrophy treated with vitamin D 3 showed a good correlation with improvement in serum Alk-Pase values. On SPECT, frontal bone activity in patients with renal osteodystrophy was significantly high compared with that in the control group. In case of renal osteodystrophy treated with partial parathyroidectomy, the frontal bone activity was markedly decreased compared with findings before surgery. (J.P.N.)

    Objective: The present study was designed to investigate the ameliorative potential and possible mechanism of hydroalcoholic extract of flowers of P. granatum in glycerol-induced acute renal failure (ARF) in rats. Materials and Methods: The rats were subjected to rhabdomyolytic ARF by single intramuscular injection of hypertonic glycerol (50% v/v; 8 ml/kg) and the animals were sacrificed after 24 hours of glycerol injection. The plasma creatinine, blood urea nitrogen, creatinine clearance, and histopathological studies were performed to assess the degree of renal injury. Results: Pretreatment with hydroalcoholic extract of flowers of P. granatum (125 and 250 mg/kg p.o. twice daily for 3 days) significantly attenuated hypertonic glycerol-induced renal dysfunction in a dose-dependent manner. BADGE (Bisphenol-A-diglycidyl ether) (30 mg/kg), a peroxisome proliferator-activated receptor (PPAR)-γ antagonist, and N(omega)-nitro-l-arginine-methyl ester (L-NAME) (10, 20, and 40 mg/kg), nitric oxide synthase inhibitor, were employed to explore the mechanism of renoprotective effects of Punica granatum. Administration of BADGE (30 mg/kg) and L-NAME (40 mg/kg) abolished the beneficial effects of P. granatum in glycerol-induced renal dysfunction. Conclusion: Hydroalcoholic extract of flowers of P. granatum has ameliorative potential in attenuating myoglobinuric renal failure and its renoprotective effects involve activation of PPAR-γ and nitric oxide-dependent signaling pathway.

  11. Potential benefits of resistance exercise training on nutritional status in renal failure.

    Resistance or strength exercise training may help reverse the malnutrition common among patients in chronic renal failure and delay the progression of renal disease. Resistance training is characterized by resisting, lifting, and lowering weights. It results in muscle mass accretion, improved physical function, and slowed progression of muscle wasting. Resistance exercise training for a period of 8 to 12 weeks results in significant increases in muscle mass, muscle strength, and muscle function in frail "healthy" elderly individuals as well as in specific patient populations. States of malnutrition leading to muscle wasting directly affect lean tissue mass and functional capacity. Even at dietary protein intake below the Recommended Dietary Allowances, resistance training appears to exert an anabolic effect by improving energy intake and protein use allowing nitrogen retention. The potential benefits of resistance exercise extend beyond this direct impact on protein metabolism. They include improvements in functional capacity such as gait, balance, mobility, strength, exercise tolerance, improved glucose uptake, insulin sensitivity, and self-efficacy and self-esteem. Currently, the effects of resistance exercise in renal patients are unknown, although they are well shown in the case of other diseases. The potential benefits that resistance exercise training may have on muscle mass and function, nutritional status, hyperglycemia, disease progression, and the overall mental well-being of renal patients deserve further investigation. As an adjunct to current treatment modalities for chronic renal failure, resistance exercise may serve as a cost-effective, interdisciplinary, noninvasive approach to counteract malnutrition and improve the quality of life.

    Membranoproliferative glomerulonephritis (MPGN) is a common extramedullary renal presentation in chronic lymphocytic leukemia (CLL) and can present with either a frank renal failure or proteinuria. One of its etiologies has been attributed to a paraneoplastic, immune complex phenomenon occurring in CLL. Although there is no standard of care in such patients, use of anti-CD20 monoclonal antibodies like rituximab have been used before in such patients with variable responses. Obinutuzumab is a novel, type II, immunoglobulin-G1 monoclonal antibody with a higher efficacy than rituximab and has an established safely profile in patients with comorbidities and poor renal functions. There are no such reported cases of MPGN in CLL being treated with obinutuzumab. We used the standard doses of obinutuzumab in our elderly patient (78-year-old woman) with high-risk CLL due to an underlying TP53 mutation, along with a MPGN-related acute renal failure. The patient achieved complete remission after six cycles of obinutuzumab; however, she remained positive for minimal residual disease on flow cytometry. Her renal function improved completely, suggesting a complete response of her underlying MPGN. Obinutuzumab has an established safety profile in patients with CLL, but our case is the first reported case of a paraneoplastic, immune complex-mediated MPGN in CLL being treated with obinutuzumab. Obinutuzumab should be explored as a potential option in patients with CLL and MPGN. Copyright © 2016 King Faisal Specialist Hospital & Research Centre. Published by Elsevier B.V.

    To investigative clinical and pathological characteristics of IgA nephropathy with chronic renal failure. Clinical and pathological findings from 65 cases of IgA nephropathy with chronic renal failure were reviewed. Pathological characteristics of all the cases were analyzed according to WHO definition and Oxford Classification. Evaluating the severity of pathological lesions by the Katafuchi R semiquantitative scoring system, and analyzing their relationship with clinical indexes of renal function. Of all 65 cases the male and female ratio was 1.4, and the mean age was 37 ± 13 years old. Levels of systolic pressure, mean arterial pressure (MAP), blood urea nitrogen (BUN), serum creatinine (Scr), uric acid (UA), album (Alb), serum IgG and 24 h urinary protein were related with eGRF level (p  0.05). IgA nephropathy with chronic renal failure usually occurred in young adults, and it had severe clinical condition and pathological changes, while there was no significant relationship between them.

    Tissue preconditioning, whereby various short-term stressors initiate organ resistance to subsequent injury, is well recognized. However, clinical preconditioning of the kidney for protection against acute kidney injury (AKI) has not been established. Here we tested whether a pro-oxidant agent, iron sucrose, combined with a protoporphyrin (Sn protoporphyrin), can induce preconditioning and protect against acute renal failure. Mice were pretreated with iron sucrose, protoporphyrin, cyanocobalamin, iron sucrose and protoporphyrin, or iron sucrose and cyanocobalamin. Eighteen hours later, ischemic, maleate, or glycerol models of AKI were induced, and its severity was assessed the following day (blood urea nitrogen, plasma creatinine concentrations; post-ischemic histology). Agent impact on cytoprotective gene expression (heme oxygenase 1, hepcidin, haptoglobin, hemopexin, α1-antitrypsin, α1-microglobulin, IL-10) was assessed as renal mRNA and protein levels. AKI-associated myocardial injury was gauged by plasma troponin I levels. Combination agent administration upregulated multiple cytoprotective genes and, unlike single agent administration, conferred marked protection against each tested model of acute renal failure. Heme oxygenase was shown to be a marked contributor to this cytoprotective effect. Preconditioning also blunted AKI-induced cardiac troponin release. Thus, iron sucrose and protoporphyrin administration can upregulate diverse cytoprotective genes and protect against acute renal failure. Associated cardiac protection implies potential relevance to both AKI and its associated adverse downstream effects. Copyright © 2016 International Society of Nephrology. Published by Elsevier Inc.

    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.

    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.

    The effects of oral adsorbent, AST-120 (Kureha Chemical Ind. Co., Tokyo), were studied in the rat model of subtotal nephrectomy. In 34 female Sprague-Dawley rats, three quarters of the renal mass were removed from the left kidney by ligation of 3 branches of the left renal artery. One week later, the right kidney was removed. Two days after right nephrectomy, control rats were fed standard rat chow ad libitum, while AST-120-treated rats were fed standard rat chow containing AST-120 ad libitum. The animals were observed for 9 weeks. Of the control rats, some became severely ill and appeared to be almost dying before 9 weeks, while paired AST-120-treated rats appeared well. Body weight was maintained better in AST-120-treated rats than in control rats. At completion of the study, levels of BUN and serum creatinine were lower and glomerular filtration rate and renal plasma flow rate were higher in AST-120-treated than in control rats (p < 0.05), although there was no statistically significant difference in proteinuria. Serum uremic peak 2a measured by high-performance liquid chromatography, which is considered to correspond to uremic toxins, was statistically lower in AST-120-treated rats (p < 0.05). Finally, a marked reduction in the degree of glomerular sclerosis was noted in AST-120-treated versus control rats (p < 0.05). The results indicate that AST-120 is effective in the treatment of chronic renal failure in terms of reducing uremic symptoms as well as preserving renal function and glomerular architecture. The data also indicate that a reduction in uremic toxins could delay the progressive damage of renal function and glomerular architecture in chronic renal failure.

The first case was a 62-year-old male who had been diagnosed as having diabetes 25 years before. He had diabetic retinopathy of Scott IIIb. Before head computerized tomography, the serum BUN was 37 mg/dl, and creatinine was 4.1 mg/dl. Oliguria began immediately after the scanning and confinued for 48 hr. The serum levels of BUN and creatinine rose to 106 and 7.7 mg/dl, respectively. Case 2 was a 49-year-old male who had been diagnosed as having diabetes 15 years before. He showed Scott IIb and IV retinopathy. The BUN and creatinine levels in the serum were 32 and 2.3 mg/dl, respectively. After receiving head computerized tomography, he developed oliguria and remained oliguric for 48 hr. During that period, the serum levels of BUN and creatinin were elevated to 112 and 7.5 mg/dl, respectively. Fortunately, both of these patients recovered from the oliguria without resorting to hemodialysis. The iodine contrast medium routinely used for contrast enhancement in the head computerized tomography was implicated in the acute renal failure of these patients. Only elevn cases have so far been reported in the literature who developed acute renal failure following computerized tomography. In view of the three or four times greater dosis of iodine contrast medium employed in computerized tomography compared to intravenous pyelography, the acute incidence of such complications might be much higher. Among the thirteen cases including the two reported here, as many as eight were diabetic. It is well recongnized that the incidence of acute renal failure after intravenous pyelography is particularly high in cases of diabetic nephropathy. (author)

    Estimation of blood volume was carried out in 20 healthy subjects and in 25 patients suffering from chronic renal failure using radioactive 51 Cr. A detailed history, physical examination and investigations were also undertaken. On statistical evaluation, the red cell volume was diminished significantly in males and females but rise in blood volume was insignificant. Plasma volume was raised significantly in females but was insignificant in males. The reduction in red cell volume is due to reduced red cell mass because of chronic renal disease. Plasma volume may be elevated in order to compensate for decreased red cell volume. The variability in these two parameters results in variable blood volume. (author)

    End-stage renal disease patients who have been on long-term hemodialysis tend to develop central nervous system complications. The most common neurologic complications in this patient group include white matter changes, cerebral atrophy, osmotic demyelination syndrome, dialysis encephalopathy, hypertensive encephalopathy, intracranial hemorrhage, infarct, sinus thrombosis, and infection. Clinical evaluation of these patients is somehow complicated and MRI is important before establishment of the therapy. The purpose of this article is to illustrate the range of MRI findings of neurologic complications in end-stage renal failure patients on hemodialysis with etiologic factors. (orig.)

    Two hundred and thirty-four measurements of standard 51Cr-EDTA plasma clearance were made in 50 patients with severe chronic renal failure. Based on these data two calculation methods were attempted using one plasma sample drawn 24 h after injection of 51Cr-EDTA. One of the methods used the 'one...... renal dysfunction (estimated clearance values below 21 ml/min) may be determined with adequate precision by one plasma sample drawn at 24 h after injection of the tracer without sampling at 5 h. This appears to be a very practical simplification....

    Full Text Available Typhoid fever is an important health problem worldwide but its incidence is more in developing countries. Hepatic involvement is common, but both hepatic and renal involvement is rare in typhoid fever. We report a case of typhoid fever presenting with hepatitis and acute renal failure. A 17 year old male presenting with fever and pain abdomen was found to have raised blood urea, creatinine, liver enzymes and bilirubin. Widal and typhidot (IgM,IgG test were positive. His symptoms subsided and deranged parameters resolved with treatment of typhoid fever.

    Acute renal failure with severe loin pain and patchy renal ischemia after anaerobic exercise (ALPE) is exercise-induced acute renal failure that occurs without myoglobinuria. We describe a typical case involving an 18-year-old man. Generally, patients with ALPE are advised to avoid anaerobic exercise due to risk of recurrence, but our patient continued and went on to become a professional cyclist without relapse. About 51% of ALPE cases involve patients with renal hypouricemia. His serum uric acid levels were rather high, at 6.4 mg/dL. He is the first patient with ALPE to succeed as a professional athlete in an anaerobic sport.

    Acute renal failure (ARF) is one of the most common problems encountered in hospitalized critically ill patients. In recent years great effort has been focused on the introduction of herbal medicine as a novel therapeutic agent for prevention of ARF. Hence, the current study was designed to investigate the effect of Açai berry extract (ABE) on glycerol-induced ARF in rats. Results of the present study showed that rat groups that received oral ABE in a dose of 100 and 200 mg/kg/day for 7 days before or 7 days after induction of ARF by a single intramuscular glycerol injection reported a significant improvement in kidney functions tests [decrease in serum urea, serum creatinine, and blood urea nitrogen (BUN)] when compared to the ARF model groups. Moreover, there was significant amelioration in renal oxidative stress markers [renal catalase (CAT), renal reduced glutathione (GSH)] and renal histopathological changes in the ABE-treated groups when compared to ARF model groups. The most significant improvement was reported in the groups where ABE was administered in a dose 200 mg/kg/day. These results indicate that ABE has a potential role in ameliorating renal damage involved in ARF.

    Heart failure is characterized by the loss of sympathetic innervation to the ventricles, contributing to impaired cardiac function and arrhythmogenesis. We hypothesized that renal denervation (RDx) would reverse this loss. Male Wistar rats underwent myocardial infarction (MI) or sham surgery and progressed into heart failure for 4 wk before receiving bilateral RDx or sham RDx. After additional 3 wk, left ventricular (LV) function was assessed, and ventricular sympathetic nerve fiber density was determined via histology. Post-MI heart failure rats displayed significant reductions in ventricular sympathetic innervation and tissue norepinephrine content (nerve fiber density in the LV of MI+sham RDx hearts was 0.31 ± 0.05% vs. 1.00 ± 0.10% in sham MI+sham RDx group, P renal nerve activity and cardiac sympathetic nerve innervation in heart failure. Our findings show denervating the renal nerves improves cardiac sympathetic innervation and function in the post-MI failing heart. Copyright © 2017 the American Physiological Society.

    Los mecanismos del da no celular en la insuficiencia renal aguda Incluyen alteraciones en la producción de energía, la permeabilidad celular y el transporte de calcio. Dichas alteraciones producen cambios progresivos en la estructura celular que pueden ser reversibles si desaparece la causa que llevó a la falla renal, excepto cuando se alcanza la fase final de la lesión de la membrana y se llega a necrosis celular. Este mismo fenómeno probablemente ocurre tambIén en situaciones clínicas.

    The mechanisms of cellular damage In acute renal failure Include alterations In energy production, cell membrane permeability and calcium transport. These changes lead to progressive damage of the whole cellular structure which In general can be reversible If the precipitating cause disappears, except when the final stages of cell membrane lesion take place and cellular necrosis has occurred. This phenomenon probably applies for the clinical settling as well.

    Full Text Available Background : Plasma B-type natriuretic peptide (BNP is the diagnostic tool for acute heart failure (AHF.This natriu­retic peptide level depends on renal function, through renal metabolism and excretion. Therefore we examined the effect ofrenal impairment on plasma BNP level during diagnosis of AHF.Objective: The objective of the study was to assess the effect of renal dysfunction on plasma BNP level and to determine appropriate cutoff value of plasma BNP to diagnose the patients of AHF with renal insufficiency.Methods: This cross sectional analytical study was conducted in the Depart­ment of Biochemistry Bangabandhu Sheikh Mujib Medical University (BSMMU. The study was done among 90 AHF patients selected from cardiology emergency department during the period of July 2012 to June 2013. After enrollment plasma BNP concentration was measured and eGFR was estimated from serum creatinine by the four parameter Modifica­tion of Diet and Renal Disease (MORD equation and then grouped into two groups on the basis of empirical cut off value of eGFR 60 ml/min/1.73 m2Results: In this study a significant negative correlation was found between plasma BNP evel and eGFR (P<0.001 , with higher BNP levels observed as eGFR declined. The optimal BNP cutoff value for diagno­sis of AHF patients with renal insufficiency was 824 pg/ml. At this cutoff level AHF with renal insufficiency could be diagnosed with sensitivity and specificity of 84% and 71 %, respectively.Conclusions: By adjusting the cutoff value, plasma BNP can be used to diagnose AHF with renal insufficiency with an acceptable sensitivity and specificity.

    Screening colonoscopy with polipectomy reduces colonorectal cancer incidence and mortality. An adequate bowel cleansing is one of the keys to achieving best results with this technique. Oral sodium phosphate solution (OSP) had a widespread use in the 90s decade. Its efficacy was similar to polyethylene glycol (PEG) solution, but with less cost and convenient administration. Series of patients with acute renal failure due to OSP use have been reported. However, large cohorts of patients found no difference in the incidence of renal damage between these two solutions. From 2006 to 2009 we identified twelve cases of phosphate nephropathy after colonoscopy prepared with OSP. All patients were followed up to six months. All patients had received just a single dose. We analyzed 12 cases with phosphate nephropathy; three patients debuted with AKI and nine patients had chronic renal injury. Four cases were confirmed with renal biopsy. One patient with AKI needed hemodialysis at diagnosis without subsequent recovery. Two patients (both with chronic damage) fully recovered their previous renal function. The remaining patients (nine) had an average loss of estimated glomerular filtration rate of 24ml/min/1.73m(2). The use of OSP can lead to both acute and chronic renal damage. However, chronic injury was the most common pattern. Both forms of presentation imply a significant and irreversible loss of renal function. Further studies analyzing renal damage secondary to bowel cleaning should consider these two different patterns of injury. Copyright © 2016 Sociedad Española de Nefrología.

    Objective was to investigate the impact of tetrahydrobiopterin (BH4) supplementation on the markers of inflammation and on the histological picture of the kidney in chronic renal failure C-reactive protein (CRF) induced in rats by subtotal nephrectomy (SNx). This study was performed at the Faculty of Medicine, King Saud University, Riyadh, Saudi Arabia during the period from December 2005 to January 2007. Chronic renal failure was induced by 5/6 SNx in 20 male Wister rats and another 10 rats were sham operated by flank incision and served as controls. Ten SNx rats received 10 mg/kg-1 BH4 intraperitoneally daily for 4 weeks. Plasma C-reactive protein (CRP), interlukin-6 (IL-6), malondialdehyde (MDA) and kidney functions were measured in all rats. Histopathological examination of kidney tissues was also performed. Untreated CRF rats showed significant elevation of plasma CRP, IL-6 and MDA levels and significant decrease in plasma albumin and total protein levels, tubuloglomerular fibrosis and interstitial tubular infiltration with inflammatory cells in comparison with the sham-operated rats. Tetrahydrobiopterin treatment decreased CRP, IL-6, MDA levels and decreased tubuloglomerular fibrosis and interstitial inflammation in treated CRF rats. Supplementation with exogenous BH4 decreased markers of inflammation and protected the kidney against post-renal mass reduction histological damage. Restoration of intracellular BH4 balance could normalize nitrous oxide production. Therefore, BH4 might be a promising strategy in attenuating inflammation in CRF. This may decrease endothelial dysfunction and limit the associated cardiovascular morbidity and mortality of this disease. (author)

    Objective: To explore the effect of intravenous or intra-renal-capsular administration of astragalus and dopamine on the serum NO and renal tissue NO, ET contents in rat models of acute renal failure. Methods: Experimental rat models of acute renal failure induced by intraperitoneal injection of E. Coli endotoxin (lipo-polysaccharide) were prepared (n=60). Treatment with astragalus and dopamine was administered via either intravenous on intra-renal-capsular route (n=20 in each group). Serum NO and renal tissue NO (with nitric acid reductase method), ET (with RIA) contents were determined at 4, 8, 12, 16h after injection of endotoxin. Twenty shock models were left untreated and additional twenty rats receiving saline injection only served as controls. Results: In the intravenously treated group, the increase of serum NO and renal tissue NO, ET contents were significantly less than those in the untreated group (P<0.05). In the group treated via the intracapsular route , the increase of renal tissue NO and ET contents were much less than those in the intravenous group at 12 and 16h (P<0.05). Conclusion: Combined treatment with astragalus and dopamine could abate the abnormally high renal tissue contents of NO and ET after endotoxin shock in experimental rats and treatment with intra capsular administration seems to be more effective.

    to determine levels of galectin-3, markers of renal dysfunction, and plasma oxidative stress; to assess their correlation in patients with chronic heart failure (CHF) of various severity. We included in this study 157 CHF patients (with documented prior myocardial infarction. Patients were divided into 3 groups according to their NYHA functional class (group 1 - class II n=60, group 2 - class III n=52, group 3 - class IV n=45). All patients underwent clinical examination, echocardiography. Laboratory parameters included measurement of plasma levels of galectin-3, NT-proBNP, as well as markers of oxidative stress (oxidized low density lipoprotein cholesterol [oxLDLC], SH-groups) and renal dysfunction (creatinine, uric acid, cystatin-C). The level of galectin-3 (median) in groups 1, 2, and 3 was 10, 19 and 38 ng/ml respectively. There were significant differences between groups (pmarkers of renal dysfunction and plasma oxidative stress.

    To study serum leptin level in chronic renal failure (CRF) hemodialysis patients and the relationship between serum leptin level and residue renal function, body composition, and indices of malnutrition, 31 end-stage CRF hemodialysis patients and 38 healthy people were enrolled. Serum leptin levels were detected by radioimmunoassay. BMI, %Fat and LBM were measured by bioelectrical impedance analysis device. Alb, Chol, Hgb, BUN, SCr and Ccr of the patients were also examined. Results showed that Serum leptin level in end-stage CRF hemodialysis patients was markedly higher than that in healthy controls (P 0.05). Conclusion: Hyperleptinemia existed in end-stage CRF hemodialysis patients and might cause the loss of LBM. The leptin level was not correlated with residue renal function, but it could reflect the fat content. However, serum leptin did not play a significant role in protein malnutrition in end-stage CRF hemodialysis patients

    MR imaging of the kidney was performed in 6 patients with acute renal failure (ARF) secondary to rhabdomyolysis caused by snake bite (n = 4), crush injury (n = 1), and carbon monoxide poisoning (n = 1). A test for urine myoglobin was positive in all 6 patients and MR imaging was done 6 to 18 days after the causative event of the rhabdomyolysis. MR images in all 6 patients showed globular swelling of the kidneys, preserved corticomedullary contrast on T1-weighted images, and obliteration of corticomedullary contrast on T2-weighted images. Unlike other medical renal diseases in which corticomedullary contrast is lost on T1-weighted images, preservation of the corticomedullary contrast on T1-weighted MR images with globular renal swelling was a constant finding in patients with ARF secondary to rhabdomyolysis.

  17. PHYSIOPATHOLOGY OF ACUTE RENAL FAILURE.NEW CLUES FOR AN OLD DILEMMA

    Directory of Open Access Journals (Sweden)

    Carlos G. Musso

    2008-01-01

    Full Text Available Acute renal failure (ARF is the term used to describe the sustained and abrupt reduction of the glomerular filtration, which causes the retention of waste products that come from the metabolism. Normally, the mechanisms potentially involved in ARF are divided into: pre-renal, parenchymatous, and post-renal. Regarding the etiology of the parenchymatous ARF, it would seem to be the sum of multiple pathogenic variables such as: tubular necrosis and apoptosis, alteration of the filtration barrier, retrodifusion of glomerular filtration, intrarenal vasoconstriction, contraction of the mesangium, intratubular obstruction, intersticial swelling, activation of proteolytic enzymes, and so on. Because of the above exposed data, only a multicausal perspective would seem to be adequate to understand and solve this syndrome.

    Three methods can be used to treat chronic renal failure - haemodialysis, peritoneal dialysis and renal transplantation (from a living donor or transplantation of a cadaver kidney). In 2009, 5,763 patients were treated with haemodialysis in the Czech Republic, while peritoneal dialysis was used in just 8% (458) of patients. This low number of peritoneal dialyses may be due to the still high number of chronic renal failure patients who come to dialysis centres "offthe street". Following acute initiation of haemodialysis, these patients are usually retained on haemodialysis. Poor awareness of peritoneal dialysis among patients as well as health care professionals is another reason for the low number of peritoneal dialysis patients. Peritoneal dialysis is suitable for home treatment. Peritoneum serves as the dialysis membrane, peritoneal cavity is filled with dialysis solution and the metabolism waste products and water are excreted into this solution. A base to correct metabolic acidosis then passes from dialysis solution into the body. Permanent catheter is inserted into the abdominal cavity to enable infusion of the dialysis solution. The dialysis is continual and this ensures stability of the inner environment and thus most closely resembles own kidney function. The advantages of peritoneal dialysis include longer preservation of residual renal function, inner environment stability and no need for venous access. Peritoneal dialysis is associated with a lower risk of infections. Peritoneal dialysis is contraindicated in patients after an extensive intraabdominal surgery and in patients with a stoma. Peritoneal damage is a serious complication of peritoneal dialysis; the risk increases with the treatment duration and thus peritoneal dialysis is not a long-term treatment choice. With the traditional CAPD (continual ambulatory peritoneal dialysis), the patient performs an exchange ofdialysis solution him/herself4 to 5 times a day. With APD (automated peritoneal

    Interventional catheterization procedures may be needed for patients with severe renal failure who are dependent on dialysis. To avoid the risk of fluid overload and electrolyte derangement during complex procedures in this oliguric/anuric patient population, we performed intra-procedural dialysis, either continuous renal replacement therapy (CRRT) or continous cycling peritoneal dialysis (CCPD). We performed a retrospective review of a cohort of pediatric patients, ages 0-18 years, with dialysis-dependent renal failure who received CRRT or CCPD during catheterization procedures from January 2013 to March 2016. Eight patients underwent a total of nine interventional catheterization procedures while receiving intra-procedural dialysis. Median age was 4.5 years (range 8 months to 17 years) and weight, 11.6 kg (11.2-62.6 kg). Six patients had end-stage renal disease (ESRD) and two patients had acute kidney injury (AKI), one due to hepatorenal syndrome and one due to multifactorial causes associated with congenital heart disease. The most common reason for catheterization was occlusive venous thrombosis requiring recanalization. CRRT was used during five cases and CCPD during four cases. Median procedure time was 337 min (95-651 min) and median contrast dose 4.2 mL kg -1 (1.2-8.2 mL kg -1 ). Euvolemia was maintained based on pre- and post-catheterizations weights, and no significant electrolyte abnormalities occurred based on lab monitoring during and post-procedure. Intra-procedural dialysis using CRRT or CCPD enables even small pediatric patients with severe renal failure to undergo long and complex interventional catheterizations by reducing the risk of fluid overload and electrolyte abnormalities. Collaboration between nephrology, cardiology, and dialysis teams is necessary for successful management of this challenging patient population. © 2017 Wiley Periodicals, Inc.

Study was carried out on 50 patients in the Dialysis Unit ,Al-Thawra General Hospital,Sana'a, Yemen, between September 2000 and December 2000. Study was carried out on patients who were on regular hemodialysis ; male to female ratio was1.3:1 with mean age of 39.8+ 1 2.6 years and mean dialysis duration of 61.3+-7.57 months. Study revealed the following results: 70% of patients have hypertension with mean systolic blood pressure (BP) of 151+-32mm Hg and mean diastolic BP of 94+-19mm Hg valvular was in the dysfunctions were found in 70%, heart failure in 50%, ischemic changes in 34% and finally 26% of patients have pericardial effusion where only one of the patient (2%) had pericardial rub. We concluded that CM were found higher than other centres worldwide. We recommend to re-evaluate the practice in this department particularly the efficiency of dialysis and followup of the patients. Statistically there was no significant correlation between the duration of dialysis and CM. (author)

    Acute renal failure is a serious complication in pregnancy. Not only does it result in significant maternal morbidity and mortality but also results in significant number of foetal loss. Although incidence of obstetrical acute renal failure has decreased in developed countries but still it is one of the major health problem of developing nations. The objective of this study was to study aetiology, maternal and foetal outcome in obstetrical acute renal failure. This study was conducted at Department of Nephrology, Khyber Teaching Hospital, Peshawar from August 2006 to December 2007. It was a descriptive, case series study. Female patients with pregnancy and acute renal failure, irrespective of age, were included in the study. Patients were thoroughly examined and baseline urea, creatinine, serum electrolytes, peripheral smear, prothrombin time, partial thromboplastin time, fibrinogen degradation products, renal and obstetrical ultrasound were performed on each patient and 24-hr urinary protein and bacterial culture sensitivity on blood, urine or vaginal swabs were done in selected patients. Foetal and maternal outcome were recorded. Data were analysed using SPSS. A total of 60 patients were included in the study. Mean age of the patients was 29 +- 5.4 years and duration of gestation was 33 +- 4.9 weeks. Mean gravidity was 4 +- 2.2. Sixteen patients (26.66%) were treated conservatively while 44 (73.33%) required dialysis. Postpartum haemorrhage was present in 14 (23.33%), postpartum haemorrhage and disseminated intravascular coagulation (DIC) in 11 (18.33%), eclampsia-preeclampsia in 8 (13.33%), antepartum haemorrhage in 8 (13.33%), antepartum haemorrhage with DIC in 6 (10%), DIC alone in 4 (6.66%), obstructed labour in 3 (5%), septic abortion in 3 (3.33%), HELLP (haemolysis elevated liver enzyme and low platelet) in 2 (3.33%), urinary tract infection with sepsis in 1 (1.66%) and puerperal sepsis in 1 (1.66%). Foetal loss was 40 (66.66%). Maternal mortality was 9 (15

    BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) bacteremia and sepsis are commonly treated with intravenous vancomycin. However, vancomycin treatment is associated adverse reactions, including skin rashes and nephrotoxicity. We present a case of acute renal failure due to acute tubulointerstitial nephritis associated with a diffuse leukocytoclastic vasculitic skin eruption following intravenous vancomycin treatment. CASE REPORT A 79-year-old Caucasian male patient was treated with intravenous vancomycin for MRSA bacteremia. Prior to treatment, his creatinine was normal at 0.6 mg/dl. He presented one week later with shortness of breath, lower limb edema, and acute renal failure. He had a diffuse maculopapular rash involving the trunk and both upper and lower extremities. A renal biopsy and left arm skin biopsy were examined histologically. The skin biopsy showed leukocytoclastic vasculitis. Renal biopsy showed some sclerosed glomeruli, some with mesangial proliferation, and tubulointerstitial inflammation with eosinophils and plasma cells and mild interstitial fibrosis. Although there was some renal arteriolosclerosis, no vasculitic changes were seen, and no vascular thrombosis was present. A diagnosis of leukocytoclastic vasculitis and acute tubulointerstitial nephritis secondary to intravenous vancomycin therapy was made. CONCLUSIONS Although skin reactions associated with drug therapy are common, vancomycin-associated dermal vasculitis is rare. Tubulointerstitial nephritis is also a rare association with vancomycin treatment. This case report has highlighted that patients being treated with intravenous vancomycin should be carefully observed for acute skin rashes and deterioration in renal function, which can be managed by ceasing treatment with vancomycin, steroid challenge, and preventing future exposure to similar antimicrobial agents.

    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.

    Full Text Available Summary: Renal denervation (RD is a potential novel nonpharmacological therapy for heart failure (HF. We performed bilateral catheter-based RD in 10 adult pigs and compared them with 10 control subjects after induction of HF to investigate the long-term beneficial effects of RD on left ventricular (LV function and regional norepinephrine gradient after conventional HF pharmacological therapy. Compared with control subjects, animals treated with RD demonstrated an improvement in LV function and reduction of norepinephrine gradients over the myocardium and kidney at 10-week follow-up. Our results demonstrated that effective bilateral RD decrease regional norepinephrine gradients and improve LV contractile function compared with medical therapy alone.

    We present a patient who had ingested sodium bicarbonate for treatment of alcoholic dyspepsia during forty years at increasing doses. During the last year he had used more than 50 grams daily. He presented with metabolic alkalosis, epileptic convulsions, subdural hematoma, hypertension and rhabdomyolysis with end stage renal failure, for which he had to be given regular intermittent hemodialysis treatment. Untreated hypertension and glomerulonephritis was probably present prior to all these acute incidents. Examination of the kidney biopsy revealed mesangial proliferative glomerulonephritis and arterial wall thickening causing nephrosclerosis together with interstitial calcinosis. The combination of all these pathologic changes might be responsible for the development of progressive chronic renal failure ending up with the need for continuous intermittent hemodialysis treatment.

    Transient and persistent worsening renal function (WRF) may be associated with different risks during hospitalization for acute heart failure. We compared outcomes of patients hospitalized for acute heart failure with transient, persistent, or no WRF. We identified patients 65 years or older hospitalized with acute heart failure from a clinical registry linked to Medicare claims data. We defined WRF as an increase in serum creatinine of ≥ 0.3 mg/dL after admission. We further classified patients with WRF by the difference between admission and last recorded serum creatinine levels into transient WRF (acute heart failure were associated with higher adjusted risks for 90-day all-cause postadmission mortality. Patients with persistent WRF had worse outcomes. Copyright © 2014 Elsevier Inc. All rights reserved.

    Proteinuria is routinely measured to assess renal allograft status, but the diagnostic and prognostic values of this measurement for renal transplant pathology and outcome remain unclear. We included 1518 renal allograft recipients in this prospective, observational cohort study. All renal allograft biopsy samples with concomitant data on 24-hour proteinuria were included in the analyses (n=2274). Patients were followed for ≥7 years post-transplantation. Compared with proteinuria failure were 1.14 (95% confidence interval [95% CI], 0.81 to 1.60; P=0.50), for proteinuria 0.3–1.0 g/24 h, 2.17 (95% CI, 1.49 to 3.18; P3.0 g/24 h, independent of GFR and allograft histology. The predictive performance of proteinuria for graft failure was lower at 3 months after transplant (area under the receiver-operating characteristic curve [AUC] 0.64, P3 months after transplant (AUC 0.73, P1.0 g/24 h. These data support current clinical guidelines to routinely measure proteinuria after transplant, but illustrate the need for more sensitive biomarkers of allograft injury and prognosis.

    2003-01-01

    There is abundant evidence that chronic renal failure (CRF) and end-stage renal disease (ESRD) alter drug disposition by affecting protein and tissue binding and reducing systemic clearance of renally cleared drugs. What is not fully appreciated is that CRF can significantly reduce nonrenal clearance and alter the bioavailability of drugs predominantly metabolized by the liver. Animal studies in CRF have shown a major down-regulation (40-85%) of hepatic cytochrome P-450 metabolism involving specific isozymes. Phase II reactions such as acetylation and glucuronidation are also involved, with some isozymes showing induction and others inhibition. Hepatic enzymes exhibiting genetic polymorphisms such as N-acetyl-transferase-2 (NAT-2), which is responsible for the rapid and slow acetylator phenotypes, have been shown to be inhibited by ESRD and reversed by transplantation. There is some evidence pointing to the possibility of inhibitory factors circulating in the serum in ESRD patients which may be dialyzable. This review includes all significant animal and clinical studies using the search terms "chronic renal failure,"cytochrome P-450," and "liver metabolism" over the past 10 years obtained from the National Library of Medicine MEDLINE database, including relevant articles back to 1969.

  9. Aortic Dissection and Renal Failure in a Patient with Severe Hypothyroidism

    Full Text Available Acute aortic dissection (AAD is a life-threatening condition associated with high morbidity and mortality. The most important recognized acquired cause that leads to dissection is chronic arterial hypertension. With respect to the anuria and renal failure, aortic dissection is not something that is always considered and is still not a very common presentation unless both renal arteries come off the false lumen of the dissection. However, when present, preoperative renal failure in patients with acute type B dissection has been noted to be an independent predictor of mortality. Early recognition and diagnosis is the key and as noted by previous studies as well, almost a third of these patients are initially worked up for other causes until later when they are diagnosed with aortic dissection. Here we present a case of a patient presenting with severe hypothyroidism, long-standing hypertension, and anuria. Through the case, we highlight the importance of having aortic dissection as an important differential in patients presenting with anuria who have a long standing history of uncontrolled hypertension. Pathophysiology relating to severe hypothyroidism-induced renal dysfunction is also discussed.

    Chinese herb nephropathy contains a variety of clinical features of progressive renal failure (indicated by studies conducted in Belgium) to the variant type of Fanconi's syndrome. Fanconi's syndrome has mostly been reported in Asian countries, and is characterized by proximal tubular dysfunction and slower progression to end-stage renal disease (ESRD); it also often revealed a reversible clinical course. We describe a 43-year-old woman who presented with polyuria and polydipsia caused by Fanconi's syndrome. The cause of Fanconi's syndrome was not identified because the patient denied the intake of the Chinese herbal mixture at first. Fanconi's syndrome seemed to be reversible in its early stage, but it rapidly progressed to renal failure after 3 months, despite the interruption of Chinese mixture use. A renal biopsy revealed typical findings of aristolochic acid-induced nephropathy. Aristolochic acids were also detected in the Chinese herbs that were consumed. This case highlights the variety of the clinical spectrum of aristolochic acid induced nephropathy (AAN). We emphasize that AAN should be suspected in all patients with Fanconi's syndrome, even if patients deny the intake of any Chinese herbal preparation.

    Full Text Available CONTEXT: Rhabdomyolysis is a severe and life-threatening condition in which skeletal muscle is damaged. Acute renal failure due to rhabdomyolysis has been widely described and its main pathophysiological mechanisms are renal vasoconstriction, intraluminal cast formation and direct myoglobin toxicity. OBJECTIVE: To report on a case of acute renal failure (ARF induced by rhabdomyolysis due to strenuous exercise and alcohol abuse and to describe the pathophysiology of this type of ARF. CASE REPORT: A 39-year-old man arrived at the hospital emergency service with swollen legs and lower extremity compartment syndrome. He was oliguric and had serum creatinine and urea levels of 8.1 mg/dl and 195 mg/dl, respectively. The diagnosis of rhabdomyolysis was made through clinical and laboratory findings (creatine kinase activity of 26320 IU/l. The initial treatment consisted of fluid replacement and forced diuresis. The specific treatment for compartment syndrome, such as fasciotomy, was avoided in order to prevent infection. Partial recovery of renal function was recorded, after ten hemodialysis sessions. Complete recovery was observed after two months of follow-up.

    Right ventricular (RV) function plays a pivotal role in advanced heart failure patients, especially for screening those who may benefit from left ventricular assist device (LVAD) implantation. We introduce RV contraction pressure index (RVCPI) as a new echo-Doppler parameter of RV function. The accuracy of RVCPI in detecting RV failure was compared with the criterion standard, the RV stroke work index (RVSWI) obtained through right heart catheterization in advanced heart failure patients referred for heart transplantation or LVAD implantation. Right heart catheterization and echo-Doppler were simultaneously performed in 94 consecutive patients referred to our center for advanced heart failure (ejection fraction (EF) 24 ± 8.8%, 40% NYHA functional class IV). RV stroke volume and invasive pulmonary pressures were used to obtain RVSWI. Simplified RVCPI (sRVCPI) was derived as TAPSE × (RV - right atrial pressure gradient). Close positive correlation between sRVCPI and RVSWI was found (r = 0.68; P rights reserved.

    To determine whether serum N-terminal pro-B-type natriuretic peptide (N-BNP), a biomarker of myocardial wall stress, is specific to acute heart failure (HF) in patients hospitalized with stroke. Case-control study. Tertiary hospital, Neurosciences Critical Care Unit and Stroke Unit. Consecutive patients with acute ischemic or hemorrhagic stroke who were evaluated for HF. None. Cases and controls were classified, respectively, as patients with or without HF, defined according to modified Framingham criteria. Seventy-two patients were evaluated, 39 with ischemic stroke, 22 with aneurysmal subarachnoid hemorrhage (SAH), and 11 with intracerebral hemorrhage (ICH). Thirty-four patients (47%) met criteria for HF, and 47 patients (65%) had systolic or diastolic left ventricular (LV) dysfunction on echocardiogram. Serum N-BNP was measured a median of 48 h following the onset of stroke and was increased (> 900 pg/ml) in 56 patients (78%), with higher levels in non-survivors (11898 +/- 12741 vs 4073 +/-5691; p = 0.001). In a multiple regression model, N-BNP elevation was not independently associated with HF (OR 5.4, 95% CI 0.8-36.0, p = 0.084). At a cut-off of 900 pg/ml, the sensitivity of N-BNP for HF was 94%, specificity 37%, positive predictive value (PPV) 57%, and negative predictive value (NPV) 88%. For systolic or diastolic LV dysfunction, the sensitivity of N-BNP was 89%, specificity 44%, PPV 75%, and NPV 69%. These results demonstrate that N-BNP elevation is not specific to HF or LV dysfunction in patients with acute ischemic stroke, SAH, and ICH.

    Impairment of growth in children with chronic renal failure may be due, in part to the insensitivity to the actions of growth hormone by insulin-like growth factor-I (IGF-I) because of accumulations of IGF binding proteins. There are a few studies describing the changes that occur in the growth plate in renal failure. None of these studies has simultaneously compared the modifications in the expression of selected markers of endochondral bone formation in renal failure with mild or advanced secondary hyperparathyroidism. Forty-six rats that underwent 5/6 nephrectomy (Nx) were fed either standard rodent diet (Nx-control) or high phosphorus diet to induce advanced secondary hyperparathyroidism (Nx-phosphorus) for 4 weeks. Sections of the tibia were obtained for growth plate histomorphometry, immunohistochemistry studies, and in situ hybridization experiments for selected markers of endochondral bone formation. Weight gain, gain in length, and tibial length were less in Nx animals. Serum parathyroid hormone (PTH) and phosphorus levels were higher and serum calcium levels were lower in the Nx-phosphorus group. The width of the growth plate was much shorter in the Nx-phosphorus group due to a decrease in both proliferative and hypertrophic zones. IGF-I protein and IGF binding protein-3 staining were diminished in both Nx groups without changes in the IGF-I receptor expression; the decline in IGF-I protein expression was much lower in the Nx-phosphorus group. PTH/PTH receptor protein (PTHrP) receptor mRNA transcripts decline and tartrate-resistant acid phosphastase (TRAP) staining increased only in the Nx-phosphorus group. The growth impairment in renal failure may be worsened by the severity of secondary hyperparathyroidism.
