    While acute renal failure secondary to intravascular hemolysis is well described in hemolytic anemias, recurrent acute renal failure as the presenting manifestation of a hemolytic anemia is rare. We report a patient with recurrent acute renal failure who was found to have paroxysmal nocturnal hemoglobinuria (PNH), on evaluation.

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

    Full Text Available 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.

  7. Acute renal failure secondary to rhabdomyolysis

    International Nuclear Information System (INIS)

    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.

    Acute renal failure can occur following major surgery. Predisposing factors include massive haemorrhage, sepsis, diabetes, hypertension, cardiac disease, peripheral vascular disease, chronic renal impairment and age. Understanding epidemiology, aetiology and pathophysiology can aid effective diagnosis and management. A consensus definition for acute renal failure has recently been developed. It relates to deteriorating urine output, serum creatinine and glomerular filtration rate. In the surg...

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

    Full Text Available Dengue is an acute mosquito-borne infection caused by dengue viruses from the genus flavivirus. Neurologic complications have been attributed chiefly to metabolic alterations and to focal and sometimes massive intracranial haemorrhages, but anecdotal cases and limited case series have indicated the possibility of viral CNS and skeletal muscle invasion causing encephalitis and myositis. We present a case of a 40-year-old male who presented with severe dengue myositis resulting in quadriparesis, respiratory failure and acute renal failure with red urine. His elevated serum creatine kinase (CK, serum and urine myoglobin levels justified rhabdomyolysis as the cause of acute renal failure. A muscle biopsy revealed inflammatory myositis. He required ventilator support for respiratory failure and was treated conservatively. This case highlights the severe and persistent muscle involvement in dengue which is a rarity.

  11. Radiocontrast-induced acute renal failure.

    2005-01-01

    The intravascular administration of iodinated radiocontrast media can lead to acute renal dysfunction. Even small changes in renal function have been associated with increased morbidity and mortality, making the prevention of radiocontrast nephropathy of paramount importance. This review summarizes the principal risk factors for radiocontrast nephropathy and evidence-based preventive strategies that should be used to limit its occurrence. Risk factors for radiocontrast nephropathy include preexistent kidney disease, diabetes mellitus, dose of radiocontrast used, advanced congestive heart failure, and intravascular volume depletion. Proven preventive measures include volume expansion with intravenous saline or sodium bicarbonate and the use of low-osmolar or iso-osmolar radiocontrast media. Studies evaluating N-acetylcysteine have been conflicting, with meta-analyses suggesting a small beneficial effect. Studies of other pharmacologic agents have not demonstrated clinical benefit.

    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.

    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.

    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.

    Rhabdomyolysis is a rare complication that emerges in a variety of infectious diseases, such as tsutsugamushi infection. In this study, we report a 71-year-old female patient with tsutsugamushi infection who exhibiting rhabdomyolysis and acute renal failure. On admission, an eschar, which is characteristic of tsutsugamushi infection, was found on her right flank area. Moreover, her tsutsugamushi antibody titer was 1:40960. The elevated values of serum creatinine phosphokinase (CPK), aldolase, creatinine and dark brown urine secondary to myoglobinuria are consistent with indications of rhabdomyolysis and acute renal failure due to tsutsugamushi infection. Her health improved without any residual effects after treatment with doxycyclin and hydration with normal saline. PMID:14717236

    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 pregnancy. 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 disseminated intravascular coagulation on presentation while one (2%) patient was diagnosed with hemolytic uremic syndrome. Maternal mortality was 12% (n = 6

    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. PMID:26422191

    Full Text Available Rhabdomyolysis is caused by muscle breakdown resulting in the release of myoglobin into the systemic circulation. Acute renal failure results from the nephrotoxicity of myoglobin. Heroin use is one of the causes of rhabdomyolysis and acute renal failure. Aim: The aim of this literature review was highlight the importance of early recognition and treatment by a nurse of acute renal failure from rhabdomyolysis after heroin. Method: The method followed in this review was based on retrospective studies and research, conducted during the period 2000-2012 and retracted from the international databases Medline, Pubmed, Cinahl and the Greek database Iatrotek on acute renal failure from rhabdomyolysis after heroin use. Key-words were used: acute renal failure, rhabdomyolysis, heroin, international guidelines, based-evidence nursing care. Results: The clinical presentation occurs with muscle pain, muscle weakness, and brown-redish urine. High values of CPK and myoglobin make the diagnosis. Toxicology tests confirm heroin use. For the treatment is required naloxone administration, the rapid hydration of the patient, alkalinization of urine, good diuresis, regulation of electrolyte disturbances and dialysis if necessary. Conclusions: Early recognition and treatment of acute renal failure from rhabdomyolysis after heroin use is vital for the survival of the patient. It is necessary to educate nurses on specific issues such as acute renal failure from rhabdomyolysis after heroin use and the implementation of protocols for the treatment and cure.

  2. Acute renal failure following binge drinking and nonsteroidal antiinflammatory drugs.

    1992-09-01

    Two college students who developed reversible acute deterioration in renal function following binge drinking of beer and the use of nonsteroidal antiinflammatory drugs (NSAIDs) are reported. Both patients presented with back and flank pain with muscle tenderness, but showed no evidence of overt rhabdomyolysis. The first case had marked renal failure, with a peak serum creatinine reaching 575 mumol/L (6.5 mg/dL), and acute tubular necrosis was documented by renal biopsy. The second case had only modest elevation in serum creatinine, and renal function rapidly improved on rehydration. The contribution of the potential muscle damage associated with alcohol ingestion to the changes in renal function in these two cases is not clear. However, the major mechanism for the acute renal failure was thought to be related to inhibition of renal prostaglandin synthesis in the face of compromised renal hemodynamics secondary to alcohol-induced volume depletion.

    Mujais, S K; Ivanavich, P

    1996-05-01

    The choice of hemodialysis membrane in acute renal failure has caused a heated debate, principally because of the dogmatism with which the results of preliminary clinical studies have been translated into prescription dictum. The issue, however, is not merely the limitations of these two studies, but rather the shift in emphasis they may have engendered in the approach to dialytic therapy in acute renal failure. Dogmatism based on limited or flawed data does not serve the interests of our patients, and the issue of hemodialysis in acute renal failure is far more complex than the exaggerated importance of membrane choice.

    A 27 years old woman was admitted due to abdominal cramps, jaundice and oligoanuria, starting 48 hours after eating Chinese food. Hepatic biochemical tests, abdominal ultrasound and retrograde pyelography were normal. The urine was intensely orange colored and microscopic analysis was normal. The serum creatinine and urea nitrogen on admission were 4.59 and 42.5 mg/dl and rose to 13.5 and 72.4 mg/dl, respectively, at the 6th hospital day. Oliguria lasted only 48 hours. Dialysis was not used, since the patient was in good general condition and uremic symptoms were absent. On the 7th day, azotemia began to subside and at the 14th day, serum creatinine was 1.0 mg/dl. Before hospital discharge, she confessed the ingestion of 2.000 mg of phenazopyridine, during a nervous breakdown, aiming to sleep deeply. Remarkable was the persistence of the orange color of her urine during several days and the dissociation between the rate of increase of serum creatinine with respect to urea nitrogen. This is an unusual case of acute renal failure caused by an overdose of a drug, commonly prescribed for urinary tract infections. PMID:12879816

    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.

  6. Acute renal failure and severe thrombocytopenia associated with metamizole

    2014-01-01

    Full Text Available Metamizole or dipyrone is a pyrazolone derivative that belongs to the non-steroidal anti-inflammatory drugs. Its main side-effect is hematological toxicity. Thrombocytopenia due to metamizole is rare and is usually associated with the involvement of the two other blood series. Drug-induced thrombocytopenia is more frequently related to immune mechanisms, and the diag-nosis is still largely made by exclusion of other causes and by correlation of timing of thrombocytopenia with the administration of drug. Metamizole may cause acute renal failure due to hemodynamic renal failure/acute tubular necrosis and/or acute tubulointerstitial nephritis. We report a case of acute renal failure and severe thrombocytopenia after metamizole. As far as we know, this combination of adverse effects from this drug has not been reported previously.

    Djenkol beans or jering (Pithecellobium jeringa) is a traditional delicacy consumed by the local population in Malaysia. Jering poisoning or djenkolism is characterized by spasmodic pain, urinary obstruction and acute renal failure. The underlying pathology is an obstructive nephropathy, which is usually responsive to aggressive hydration and diuretic therapy. We present a case of djenkolism following ingestion of jering. The patient required urgent bilateral ureteric stenting following the failure of conservative therapy. Healthcare providers need to recognize djenkolism as a cause of acute renal failure and the public educated on this potential health hazard.

    AIM: Clostridium difficile infection is primarily a nosocomial infection but asymptomatic carriers of Clostridium difficile can be found in up to 5% of the general population.Ampicillin, cephalosporins and clindamycin are the antibiotics that are most frequently associated with Clostridium difficile-associated diarrhea or colitis. Little is known about acute renal failure as a consequence of Clostridium difficile-associated diarrhea.METHODS: In this case report, we describe the course of Clostridium difficile-associated diarrhea in an 82-yearold patient developing acute renal failure. Stopping the offending agent and symptomatic therapy brought a rapid improvement of diarrhea and acute renal failure, full recovery was gained 18 d after admission. In a systematic review we looked for links between the two conditions.RESULTS: The link between Clostridium difficilr-associated diarrhea and acute renal failure in our patient was most likely volume depletion. However, in experimental studies a direct influence of Clostridium difficile toxins on renal duct cells could be shown.CONCLUSION: Rapid diagnosis, nonspecific supportive treatment and specific antibiotic treatment, especially in the elderly, may lower excess mortality Clostridium difficile-associated diarrhea and renal failure being possible complications.

    Full Text Available Rhabdomyolysis is a musculoskeletal clinical and biochemical syndrome which is seen associated with traumatic and non-traumatic causes and is known as muscular dystrophy. Rhabdomyolysis which develops following crush-type trauma (Crush syndrome is rarely seen but is a well-known clinical event in the etiology of acute renal failure. Non-traumatic rhabdomyolysis is rare. The case is here presented of a patient who was diagnosed with rhabdomyolysis on presentation with acute renal failure and to whom repeated dialysis was applied.

    Although acute renal failure is encountered with administration of nephrotoxic drugs, ischemia, or unilateral nephrectomy, there has been no effective drug which can be used in case of acute renal failure. Hepatocyte growth factor (HGF) is a potent hepatotropic factor for liver regeneration and is known to have mitogenic, motogenic, and morphogenic activities for various epithelial cells, including renal tubular cells. Intravenous injection of recombinant human HGF into mice remarkably suppre...

    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

    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.

    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.

  15. Obstetrical acute renal failure: a challenging medical complication

    International Nuclear Information System (INIS)

    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)

    2016-01-01

    Full Text Available 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.

    Full Text Available 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.

  18. Factors predicting the outcome of acute renal failure in pregnancy

    International Nuclear Information System (INIS)

    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)

    2014-06-30

    A 63-year old male was referred to our emergency unit due to acute renal failure. The level of serum renal function tests levels, blood urea nitrogen (BUN)/creatinine, were 63 mmol/L/848 μmol/L. CT (Computarised Tomography) scan showed a huge bladder stone (5 cm x 6 cm x 5 cm) with increased bladder wall thickness. Post-renal acute renal failure due to bilateral ureterohydronephrosis was diagnosed. The huge bladder stone was considered to be the cause of ureterohydronephrosis and renal failure. The patient was catheterised and received haemodialysis immediately. He received haemodialysis four times during ten days of hospitalization and the level of serum renal function tests levels (BUN/ creatinine) decreased 18 mmol/L/123 μmol/L. After improvement of renal function, we performed cystoscopy that demonstrated normal prostatic urethra and bladder neck and bilaterally normal ureteral orifices. Bladder wall was roughly trabeculated and Bladder outlet was completely obstructed by a huge bladder stone. After cystoscopy open, cystolithotomy was performed to remove calcium phosphate and magnesium ammonium phosphate stone weighing 200 g removed. Four days after operation the patient was discharged uneventfully and urethral catheter was removed on the seventh day. Post-renal acute renal failure due to large bladder stones is rare in literature. According to the our knowledge; early diagnosis of the stone avoid growth to large size and prevent renal failure.

    Imaging techniques, especially ultrasonography and Doppler, can give an effective assistance in the differential diagnosis of acute renal failure (ARF). An resistance Index (RI) value >0.75 is reported as optimal in attempting differential diagnosis between acute tubular necrosis (ANT) and prerenal ARF. In hepatorenal syndrome (HRS) RIs is very increased. In some renal vasculitis, as nodose panarteritis (PN), hemolytic-uremic syndrome (HUS), thrombotic thrombocytopenic purpura (TTP), parenchymal perfusion is reduced and RI increased. In lupus nephritis the RI values are correlated with creatinine level and normal RI are considered as a good prognostic tool. In acute primitive or secondary glomerulonephritis (GN), RI value is normal, with diffuse parenchymal hypervascularization. In acute crescentic and proliferative GN and tubulo-interstitial disease, color Doppler (CD) and power Doppler (PD) reveal a decreased renal parenchymal perfusion, which correlates with increased RI values. In acute thrombosis of renal artery, US color Doppler (DUS) reveals either an absence of Doppler signal or a tardus-parvus pulse distal to the vascular obstruction. In this situation it is possible to visualize hyperthropic perforating vessels that redirect their flow from the capsular plexus to the renal parenchyma. In acute thrombosis of the renal vein Doppler analysis of parenchymal vessels reveals remarkable RI values, sometimes with reversed diastolic flow. In postrenal ARF an adjunct to the differentiation between obstruction and non obstructive dilatation can be found through RIs. Diagnostic criteria of obstruction as reported by literature are: RI>0.70 in the obstructed kidney and, mostly, a difference in RI between the 2 kidneys >0.06-0.1.

  5. Paroxysmal nocturnal hemoglobinuria: rare cause of acute renal failure

    Full Text Available Paroxysmal nocturnal hemoglobinuria is a rare acquired disease, characterized by hemolytic anemia, recurrent infections, cytopenias, and vascular thrombosis. It occurs by non-malignant clonal expansion of one or more hematopoietic stem cells that acquired somatic mutations in PIG-A gene linked to chromosome X. This mutation results in lower erythrocyte expression of CD55 and CD59 surface proteins and consequently increased susceptibility to the complement system. The renal involvement is generally benign, resulting in mild impairment in urinary concentration. Acute renal failure requiring hemodialytic support accompanying PNH is rarely observed. The authors report a case of a 37-year-old male who presented with bicytopenia (hemolytic anemia and thrombocytopenia associated with acute renal failure requiring dialysis. Diagnosis was challenging because of the rarity and unfamiliarity with this entity, but was confirmed by flow cytometry. In the course of the disease, acute pyelonephritis with multiple renal abscesses was diagnosed requiring prolonged antibiotic therapy. Patient outcome was favorable after the control of hemolysis and the infection treatment.

    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.

    1994-05-01

    Although acute renal failure is encountered with administration of nephrotoxic drugs, ischemia, or unilateral nephrectomy, there has been no effective drug which can be used in case of acute renal failure. Hepatocyte growth factor (HGF) is a potent hepatotropic factor for liver regeneration and is known to have mitogenic, motogenic, and morphogenic activities for various epithelial cells, including renal tubular cells. Intravenous injection of recombinant human HGF into mice remarkably suppressed increases in blood urea nitrogen and serum creatinine caused by administration of cisplatin, a widely used antitumor drug, or HgCl_2, thereby indicating that HGF strongly prevented the onset of acute renal dysfunction. Moreover, exogenous HGF stimulated DNA synthesis of renal tubular cells after renal injuries caused by HgCl_2 administration and unilateral nephrectomy and induced reconstruction of the normal renal tissue structure in vivo. Taken together with our previous finding that expression of HGF was rapidly induced after renal injuries, these results allow us to conclude that HGF may be the long-sought renotropic factor for renal regeneration and may prove to be effective treatment for patients with renal dysfunction, especially that caused by cisplatin.

    Weisbord, Steven D; Palevsky, Paul M

    2006-06-01

    Acute renal failure (ARF) is a common complication in critically ill patients, with ARF requiring renal replacement therapy (RRT) developing in approximately 5 to 10% of intensive care unit (ICU) patients. Epidemiological studies have demonstrated that ARF is an independent risk factor for mortality. Interventions to prevent the development of ARF are currently limited to a small number of settings, primarily radiocontrast nephropathy and rhabdomyolysis. There are no effective pharmacological agents for the treatment of established ARF. Renal replacement therapy remains the primary treatment for patients with severe ARF; however, the data guiding selection of modality of RRT and the optimal timing of initiation and dose of therapy are inconclusive. This review focuses on the epidemiology and diagnostic approach to ARF in the ICU and summarizes our current understanding of therapeutic approaches including RRT.

    Full Text Available Introduction. Retroperitoneal fibrosis is a rare cause of acute renal failure (ARF with only a handful of cases reported in literature. We report a case of a 40-year-old male with an incidental finding of retroperitoneal fibrosis. Case Presentation. Patient is a 40-year-old African American male with no significant past medical history who presented with a four-month history of low back pain and associated nausea with vomiting. Physical examination was significant for elevated blood pressure at 169/107 mmhg and bilateral pedal edema. Significant admission laboratory include blood urea nitrogen (BUN of 108 mg/dL, serum creatinine (Cr of 23 mg/dL, bicarbonate of 19 mg/dL, and potassium of 6.2 mmL/L. Renal ultrasound showed bilateral hydronephrosis. Post-void residual urine volume was normal. Abdominopelvic CT scan showed retroperitoneal fibrosis confirmed with fine-needle biopsy. He was treated with a combination of bilateral ureteral stent placement, hemodialysis, and steroid therapy. Four months after hospital discharge, his BUN and Cr levels Improved to 18 mg/dL and 1.25 mg/dL, respectively. Conclusion. Retroperitoneal fibrosis should be considered as a differential diagnosis in patients with acute renal failure and obstructive uropathy. Abdominal CT scan is the examination of choice for diagnosis. Full resolution with treatment depends on the duration of obstruction.

  14. Preventing acute renal failure is crucial during acute tumor lysis syndrome

    Directory of Open Access Journals (Sweden)

    Darmon Michael

    2007-01-01

    Full Text Available Tumour Lysis syndrome (TLS is characterized by the massive destruction of tumoral cells and the release in the extracellular space of their content. While TLS may occur spontaneously before treatment, it usually develops shortly after the initiation of cytotoxic chemotherapy. These metabolites can overwhelm the homeostatic mechanisms and cause hyperuricemia, hyperkalemia, hyperphosphatemia and hypocalcemia. Moreover, TLS may lead to an acute renal failure (ARF. In addition to the hospital mortality induced by the acute renal failure itself, development of an ARF may preclude optimal cancer treatment. Therefore, prevention of the acute renal failure during acute tumor lysis syndrome is mandatory. The objective of this review is to describe pathophysiological mechanisms leading to acute tumor lysis syndrome, clinical and biological consequences of this syndrome and to provide up-to-date guidelines to ensure prevention and prompt management of this syndrome.

    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.

    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 months following the

    Therapy of prolonged acute renal failure regularly requires a renal replacement therapy. This can be achieved by different extracorporal renal replacement therapies (ERRT) or by peritoneal dialysis. ERRT are classified according to the physical principle underlying toxin elimination as hemodialysis (diffusion) and hemofiltration (convection). Another classification refers to intermittent or continuous application modes. Biocompatibility of membranes is judged according to their activation of the complement system. Prospective randomized studies did not consolidate the assumptions about the benefit of particular modalities proposed on theoretical foundations. Mortality, duration and complication rates of acute renal failure are not significantly decreased by use of biocompatible membranes. Continuous modalities are not generally preferable but optimize treatment in hemodynamically unstable patients, in whom they endorse fluid balancing and maintenance of sufficient arterial blood pressure. The use of demanding hemofiltration techniques for cytokine removal should be limited to clinical studies. The effects of ERRT-"intensity" and the best timing for initiation of ERRT have not been evaluated sufficiently. The choice of the ERRT modality is subject to clinical judgement (criterion: hemodynamic situation), practical aspects (criteria: availability of equipment and handling experience), and costs. Prior to their general use new and expensive technical modalities and membrane types should be thoroughly evaluated in studies with regard to outcome-related aspects such as patient survival and preservation of renal function.

    Phenazopyridine (Pyridium) is a commonly used urinary tract analgesic. It has been associated with yellow skin discoloration, hemolytic anemia, methemoglobinemia, and acute renal failure, especially in patients with preexisting kidney disease. We report a 17-year-old female with vertically transmitted human immunodeficiency virus (HIV) infection, presenting with acute renal failure and methemoglobinemia following a suicidal attempt with a single 1,200 mg ingestion of Pyridium. She had no prior evidence of HIV nephropathy. The patient had a progressive nonoliguric renal failure on the 3rd day following the ingestion. She was treated with N-acetylcysteine, intravenous carnitine, and alkalinization of the urine. Her kidney biopsy revealed acute tubular necrosis with no glomerular changes. After 7 days of conservative management, she was discharged home with normal kidney function. To our knowledge, this is the second smallest amount of Pyridium overdose resulting in acute renal failure with no previous history of kidney disease. PMID:16897003

    This study was conducted to evaluate the effects of Zingiber officinale Roscoe (Ginger), Arabic gum (AG), and Boswellia on both acute and chronic renal failure (CRF) and the mechanisms underlying their effects. Acute renal failure was induced by 30 min ischemia followed by 24 h reperfusion, while CRF was induced by adenine feeding for 8 weeks. Prophylactic oral administration of ginger, AG, Boswellia, or vehicle (in control groups) was started 3 days before and along with adenine feeding in different groups or 7 days before ischemia-reperfusion. Ginger and AG showed renoprotective effects in both models of renal failure. These protective effects may be attributed at least in part to their anti-inflammatory properties as evident by attenuating serum C-reactive protein levels and antioxidant effects as evident by attenuating lipid peroxidation marker, malondialdehyde levels, and increasing renal superoxide dismutase activity. Ginger was more potent than AG in both models of renal failure. However, Boswellia showed only partial protective effect against both acute renal failure and CRF and it had no antioxidant effects. Finally, we can say that ginger and AG could be beneficial adjuvant therapy in patients with acute renal failure and CRF to prevent disease progression and delay the need for renal replacement therapy.

    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.

    Full Text Available OBJECTIVE: Colistin is a polymyxin antibiotic with a polypeptide structure and is effective against gram-negative bacilli. Although its use had decreased due to its side effects, it has increased again in recent years, especially for multi-drug resistant Pseudomonas aeruginosa, Klebsiella pneumoniae, Acinetobacter and Enterobacteriaceae. In the present study, patients that received colistin at one center were retrospectively analysed in terms of nephrotoxicity. MATERIAL and METHODS: Patients hospitalized and treated with colistin in the intensive care unit between January 2012 and August 2013 were analyzed. Demographic data; biochemical tests at baseline, daily during hospitalization and after discharge; and the initial, maintenance and total doses of colistin were evaluated. RESULTS: The mean age was 62±13 (31-86 years for the 27 patients with 17 (63% males that were followed-up for an average duration of 63±89 days. During follow-up, 18 patients (66.7% developed acute renal failure (ARF and 17 (63% of died. There were 12 (66.7% mortalities in the ARF group and 5 (55% in the group without ARF ( p> 0.05. The total colistin dose and leukocyte count were higher in the ARF group with 3.75±2.34 g and 12.04±5.05/mm3 than the non-ARF group at 3.32±1.86 g and 7.60±3.7/mm3 but did not reach statistical significance. CONCLUSION: ARF increases the mortality in ICU patients. Although colistin is an effective therapeutic agent used for resistant infections, we have to avoid higher doses due to its potential side effect of ARF.

    2004-01-01

    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.

    The objective of this study was to determine the risk factors of postoperative acute renal failure (ARF) in orthotopic liver transplantation (OLT). We reviewed 184 consecutive OLT. Postoperative ARF was defined as a persistent rise of 50% increase or more of the S-creatinine (S-Cr). The patients were classified as early postoperative ARF (E-ARF) (first week) and late postoperative ARF (L-ARF) (second to fourth week). Preoperative variables were age, sex, comorbidity, indication for OLT, Child-Pugh stage, united network for organ sharing status, analysis of the blood and urine, and donor's data. Intraoperative variables were systolic arterial pressure, mean arterial pressure, pulmonary capillary wedge pressure, cardiac index, and systemic vascular resistance index. Surgical technique, number of blood products transfused, need for adrenergic agonist drugs, and intraoperative complications were also important. Postoperative variables were duration of stay in the intensive care unit, time on mechanic ventilation, liver graft dysfunction, need for adrenergic agonist drugs, units of blood products infused, episodes of acute rejection, re-operations, and bacterial infections. Firstly we carried out a univariate statistical analysis, and secondly a logistic regression analysis. The risk factors for E-ARF were: pretransplant ARF (odds ratio (OR)=10.2, P=0.025), S-albumin (OR=0.3, P=0.001), duration of treatment with dopamine (OR=1.6, P=0.001), and grade II-IV dysfunction of the liver graft (OR=5.6, P=0.002). The risk factors for L-ARF were: re-operation (OR=3.1, P=0.013) and bacterial infection (OR=2.9, P=0.017). The development of E-ARF is influenced by preoperative factors such as ARF and hypoalbuminemia, as well as postoperative factors such as liver dysfunction and prolonged treatment with dopamine. The predicting factors of L-ARF differ from E-ARF and correspond to postoperative causes such as bacterial infection and surgical re-operation.

    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.

    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

    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.

    Bilateral renal vein thrombosis is an unusual etiology of acute renal failure and usually is associated with nephrotic syndrome. We report a 77-year-old man, consulting in the emergency room for anuria that appeared 24 hours after a syncope. The patient was carrier of an inferior vena cava filter prophylactically installed 17 months earlier and was not receiving anticoagulation. Serum creatinine on admission was 5.45 mg/dl and blood urea nitrogen was 54 mg/dl. Computed tomography and Doppler ultrasonography showed an extensive thrombosis of inferior vena cava and both renal veins. Heparin therapy was started with a rapid recovery of renal function and diuresis.

    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.

    Postinfectious proliferative glomerulonephritis may occur in HIV-infected patients, although it is not a common cause of severe acute renal failure in them. We report a woman with HIV infection, who developed hypocomplementemic acute nephritic syndrome 10 days after an upper respiratory infection. Systemic diseases were excluded. The serum creatinine level increased to 6.6 mg/dl. Renal biopsy showed diffuse endocapillary proliferative glomerulonephritis, with mesangial and capillary walls, granular deposits of IgG and C3 by immunofluorescence. She was given corticosteroids with progressive normalization of her renal function. No opportunistic infections have occurred during 1-year follow-up.

    Full Text Available 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: 14FNx01hepatic dysfunction + 11FNx01cISS + 18FNx01cUrea + 12FNx01cGlucose + 10FNx01pulmonary dysfunction.

    Full Text Available Surgery is the only curative modality but occasionally it can have some long term complication such as short bowel syndrome. We presented a case reporting a 63-year-old man who had subtotal colectomy with liver metastasectomy according to the colon adenocarcinoma, following the couple of months of surgery; he had acute kidney injury without any end-organ damage while he had a regular diet and nutrition. Following the regular treatment of renal failure, colorectal cancer recurrence was excluded and then he was discharged from the hospital with a normal serum creatinine level. The patient was admitted to the nephrology clinic again for acute renal failure within 3 weeks of last admission to the hospital. He also denied the insufficient oral water intake and nutrition, but laboratory examination revealed acute renal failure. We suspected for short bowel syndrome (SBS. Following the hydration, loperamide hydrochloride 10 mg/day was started and the patient was followed up with normal serum creatinine and uric acid levels. To the best of our knowledge, this is the first case report, in which a patient with short bowel syndrome presented with prerenal acute renal failure even though he had sufficient oral intake and nutrition and can be treated with hydration and loperamide hydrochloride.

    2011-01-01

    Sepsis is a clinical syndrome related to severe infection and is characterized by systemic inflammation and injury to multiple organs and functional systems. Sepsis is one of the main causes of acute renal failure (ARF). Diuretics are frequently administered during ARF. However, there is scant evidence that diuretics provide any benefit to the patients with ARF. This case report highlights the occurrence of uremia and nonrecovery of renal function after administration of diuretics in a patient with ARF caused by sepsis. It is suggested that physicians should be cautious in prescribing diuretics to patients with ARF due to septicemia. Diuretics cause uremia and may lead to false diagnosis of chronic renal failure and nonrecovery of renal function. The patient may unnecessarily require prolonged dialysis. PMID:22022011

    Full Text Available Sepsis is a clinical syndrome related to severe infection and is characterized by systemic inflammation and injury to multiple organs and functional systems. Sepsis is one of the main causes of acute renal failure (ARF. Diuretics are frequently administered during ARF. However, there is scant evidence that diuretics provide any benefit to the patients with ARF. This case report highlights the occurrence of uremia and nonrecovery of renal function after administration of diuretics in a patient with ARF caused by sepsis. It is suggested that physicians should be cautious in prescribing diuretics to patients with ARF due to septicemia. Diuretics cause uremia and may lead to false diagnosis of chronic renal failure and nonrecovery of renal function. The patient may unnecessarily require prolonged dialysis.

    Background In 2008, infants in some areas of China suffered from stones of the urinary system which were caused by melamine-contaminated milk formula. Most of the infants were asymptomatic, and a few suffered from acute renal failure induced by urinary obstruction by stones. This study aimed to assess the significance of blood purification therapy in treatment of infants with acute obstructive oligo-anuric renal failure. Corrective perception, timely diagnosis, and active treatment of this complex disease are critical factors that guarantee a quick recovery of renal function of infants and help them to prevent multiple organ system failure.Methods Thirteen infants with acute renal failure induced by urinary multiple obstruction caused by melamine-containing stones who had been admitted to Beijing Children's Hospital Affiliated to Capital Medical University in 2008 were investigated for the epidemiological characteristics, image features and indications of dialysis. All these infants were treated with dialysis. The efficacy of dialysis was compared with that of two control groups treated with cystoscopic retrograde catheterization into the ureter and medical treatment for the recovery of renal function.Results The 13 infants with life-threatening complications treated with dialysis showed a blood urea nitrogen (BUN) level of (30.9±7.9) mmol/L and a creatinine (Cr) level of (572+173) pmol/L. Of these infants, 8 were treated with peritoneal dialysis (PD), and 5 with hemodialysis (HD). Ten infants recovered to urinate 24-72 hours after dialysis and 3 infants with persistent ureteral obstruction were further treated with cystoscopic retrograde catheterization into the ureter for drainage, and urination resumed soon after the operation. The average time of PD and HD were (2.1±0.8) days and (1.2±0.4) days, respectively. The total average time of PD and HD dialysis was (1.77±0.83) days. The recovery time of renal function of infants after dialysis was (3.08±1.20) days

    Case (description) the patient is a 20 years old male smoker, who was diagnosed with type 2 diabetes mellitus in 2006. Due to the inadequate response to the previously established treatment, the pharmacotherapy was modified by introducing exenatide (up to 10 μg, twice daily) instead of insulin glargine, but maintaining the treatment with the diuretic and angiotensin II receptor antagonist drugs. Two months later, the patient exhibited a very important intolerance to exenatide (continuous nausea, vomiting, and dehydration), finally leading to ischemic acute renal failure. When the angiotensin II receptor antagonist and exenatide were suspended, a very rapid recovery of renal function was observed. Conclusion ischemic acute renal failure is supposed to be the consequence of the extracellular volume contraction caused by exenatide (the result of continuous nausea and vomiting). This adverse effect could be caused by the co-administration of diuretics and angiotensin II receptor antagonists.

    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. PMID:27165818

    We report a case of a healthy 24-year-old man who presented with acute renal failure and proteinuria while taking creatine and multiple other supplements for bodybuilding purposes. A renal biopsy showed acute interstitial nephritis. The patient recovered completely after he stopped taking the supplements. Creatine is a performance-enhancing substance that has gained widespread popularity among professional as well as amateur athletes. It is legal and considered relatively safe. Recently there have been case reports of renal dysfunction, including acute interstitial nephritis, associated with its use. Further studies are needed to evaluate the safety of creatine supplementation. It may be prudent to include a warning of this possible side effect in the product insert.

  10. Acute renal failure following contrast injection for head computerized tomography in two patients with diabetic nephropathy

    International Nuclear Information System (INIS)

    Two cases of diabetes mellitus with renal and retinal involvement developed acute renal failure after undergoing head computerized tomography. 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)

  11. NSAID nephrotoxicity revisited: acute renal failure due to parenteral ketorolac.

    1993-12-01

    The success of ketorolac as a nonnarcotic analgesic is likely to propagate its widespread use to control moderate to severe postoperative pain. Indeed, of the patients treated with ketorolac and described in the medical literature, nearly 90% had had a major surgical procedure. Since any such procedure may be associated with significant third-spacing of the fluid and result in renal hypoperfusion, care must be taken in administering ketorolac. Close attention to urine output and parameters of renal function must be maintained. Moreover, postoperative ketorolac therapy should be avoided in patients who have conditions that predispose to NSAID nephrotoxicity (as in our Case 1). Likewise, in nonsurgical patients the same degree of caution should be used with ketorolac as with any oral NSAID. Finally, since ketorolac is excreted almost entirely by the kidney, either elderly patients or patients with underlying renal insufficiency must have an adjustment of the dosing interval, or this medication should be avoided in such patients altogether.

    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.

    Ischemic ARF is characterized by progressive mitochondrial accumulation of Ca++ which is inversely correlated with the level of oxidative phosphorylation. At least two possibilities exist which would be compatible with these data 1) depressed respiration leads to Ca++ accumulation or 2) increased mitochondrial Ca++ leads to reduced mitochondrial respiration. We favor the latter hypothesis for the reasons outlined above; furthermore, this conclusion is supported by the observations of Lehninger, made some 20 years ago: first, that either oxidative phosphorylation or mitochondrial Ca++ accumulation can be accomplished by intact mitochondria but that these events cannot occur simultaneously and second, that Ca++ accumulation takes precedence over oxidative phosphorylation. Our observation made during post-ischemic reflow that mitochondrial Ca++ accumulation occurs to a significant degree, strongly suggest a potential role for mitochondrial Ca++ overload in the pathogenesis of ARF. Nevertheless, this is not an irreversible pathogenetic process. Clearly, impermeant solutes, vasodilators and Ca++ membrane blockers will alter the natural history of this injury and prevent the severity of the functional defect. A common mechanism of action may involve direct or indirect modification of cellular Ca++ overload in renal vascular and epithelial tissue. The vascular smooth muscle may then revert to a less constricted state with a subsequent more rapid recovery of renal blood flow and that the renal epithelial cell death may be minimized thereby reducing tubular obstruction.

    Rhabdomyolysis is an unusual manifestation of pheochromocytoma. Early diagnosis and prompt management are crucial, as it may have life-threatening consequences. This is the case of a 19-year-old man with bilateral pheochromocytoma complicated with rhabdomyolysis and acute myoglobinuric renal failure after surgery for nephrolithiasis. A massive catecholamine release during the procedure manifested itself as a hypertensive crisis, producing severe vasoconstriction and thereby provoking ischemia of the patient's muscle tissue. This insult resulted in rhabdomyolysis and acute myoglobinuric renal failure. After making sure that all necessary medical precautions were performed, including blood pressure stabilization with alpha receptor blockade and adequate fluid replacement, the patient successfully underwent a bilateral cortex-sparing medullar adrenalectomy. The operation specimen was reported as pheochromocytoma. PMID:18360344

  2. Aetiology, maternal and foetal outcome in 60 cases of obstetrical acute renal failure

    International Nuclear Information System (INIS)

    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%).

    Renal failure is a serious complication in patients with advanced cirrhosis. It occurs in about 20 % of patients hospitalized with cirrhosis. In about 70 % it is caused by prerenal failure, and in 30 % it is due to intrarenal causes. In about 70 % of patients with rperenal failure, renal function can be restored with fluid replacement, but the remaining 30 % are unresponsive to volume expansion. Minor increase in serum creatinine have been shown to be clinically relevant and can adversely affect survival. Therefore early efforts should be made to avoid precipitation of renal failure.Hepatorenal syndrome (HRS) is a  fully reversible impairment of renal function in patients with cirrhosis unresponsive to volume expansion characterized by an acute progressive decrease in kidney function (serumcreatinin > 1,5 mg/dl) - type 1 HRS, whereas type 2 HRS features a decrease in kidney function over a long time, mostly in patients with refractory ascites. Therapy with vasoconstrictors like terlipressin to reverse splanchnic vasodilation, together with albumin is effective in 30-50 % of patients with HRS 1 and improves survival. The only effective longterm therapy is livertransplantation. An improvement of kidney fuction before transplantation is associated with a better outcome and posttransplant kidney function.

    Objective: To study the clinical effect of continuous blood purification on acute renal failure. Methods: A total of 46 patients with acute renal failure treated with continuous renal replacement therapy in our hospital from April 2011 to December 2015 were retro-spectively analyzed. Patients choosing continuous veno-venous hemofiltration (CVVH) mode were collected into CVVH group and patients choosing continuous venovenous hemodiafiltration (CVVHDF) mode were collected into CVVHDF group, and their general condition, hospitalization conditions and blood biochemical indexes were analyzed. Results: Before and after treatment, the voided volumes and APACHE II scores of patients in CVVHDF group and CVVH group showed no differences. After treatment, the voided volumes of patients in the two groups were all higher than those before treatment and their APACHE II scores were all lower than those before treatment. The duration of continuous renal replacement therapy and the hospital stays in ICU of patients in CVVHDF group were all shorter than those in CVVH group. In CVVHDF group, the ratios of mechanical ventilation and death and the total hospitalization time had no sig-nificant differences with those in CVVH group. After treatment, the contents of blood urea nitrogen, serum creatinine, uric acid, β2 microglobulin, glutamic-pyruvic trans-aminase, aspartate transaminase, lactic dehydrogenase and creatine kinase isoenzyme of patients in CVVHDF group were all lower than those in CVVH group. Conclusions: Continuous blood purification therapy possesses exact curative effect on acute renal failure. The cleanup effect of CVVHDF mode on solutes and its protective effect on heart and liver were all superior to those of CVVH mode.

    Full Text Available Two clinical cases of patients who survived after numerous attacks of Africanized bees (600 and 1500 bee stings, respectively are reported. Clinical manifestation was characterized by diffuse and widespread edema, a burning sensation in the skin, headache, weakness, dizziness, generalized paresthesia, somnolence and hypotension. Acute renal failure developed and was attributed to hypotension, intravascular hemolysis, myoglobinuria due to rhabdomyolysis and probably to direct toxic effect of the massive quantity of injected venom. They were treated with antihistaminic, corticosteroids and fluid infusion. One of them had severe acute renal failure and dialysis was required. No clinical complication was observed during hospital stay and complete renal function recovery was observed in both patients. In conclusion, acute renal failure after bee stings is probably due to pigment nephropathy associated with hypovolemia. Early recognition of this syndrome is crucial to the successful management of these patients.Foram relatados dois casos clínicos de pacientes que sobreviveram a ataques maciços de abelhas africanizadas (600 e 1500 picadas. As reações caracterizaram-se por edema difuso e generalizado, sensação de queimação na pele, cefaléia, fraqueza, parestesia generalizada, sonolência e hipotensão. A insuficiência renal aguda desenvolveu-se, tendo sido atribuída à hipotensão, hemólise intravascular, mioglobinúria devido à rabdomiólise e provavelmente ao efeito tóxico direto da grande quantidade de veneno injetada. Os pacientes foram tratados com agentes anti-histamínicos, corticosteróides e reposição hídrica. Um paciente apresentou quadro grave de insuficiência renal aguda necessitando de tratamento dialítico. Nenhuma complicação clínica foi observada durante a internação e ambos evoluíram bem com recuperação completa da função renal.

    We present a case of acute hemolytic anemia, renal failure, and Clostridium perfringens bacteremia in a patient with acute myelogenous leukemia. The high fatality of C. perfringens bacteremia requires that clinicians recognize and rapidly treat patients at risk for this infection. Although other hemolytic processes are in the differential diagnosis of these events, the presence of high fever, chills, and rapidly positive blood cultures may help narrow the diagnosis. Most cases of C. perfringens bacteremia have a concomitant coinfection, which makes broad spectrum empiric therapy essential. There is a high mortality rate of C. perfringens infections associated with leukemia.

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

    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.

    Full Text Available SUMMARY: Acute renal failure is a syndrome that usually runs with an increase in creatinine and urea plasma levels. However, there are clinical situations in which this syndrome may run with an increase in plasma creatinine keeping normal the urea one. In this report we present a case of acute renal failure with normal plasma urea level secondary to an acute pyelonephritis in a single kidney patient. The patient had an increased fractional excretion of urea which could explain the normal plasma urea levels found despite of his reduced glomerular filtration. This increased urea excretion state was interpreted as a consequence of the nephrogenic diabetes insipidus and alteration of the intra-renal urea reciclying process that the acute pyelonephritis induced. In conclusion: Acute pyelonephritis in a single kidney patient can appear as a pattern of acute renal failure with normal plasma urea levels.RESUMEN: La insuficiencia renal aguda es un sindrome que característicamente cursa con niveles plasmáticos elevados de urea y creatinina. Sin embargo, hay situaciones clínicas en las cuales este sindrome puede cursar con un incremento de la creatininemia sin presentar elevación de la uremia. En este reporte presentamos un caso clínico de una insuficiencia renal aguda con uremia normal secundaria a una pielonefritis aguda en un paciente con riñón único. El paciente presentaba una elevada excreción fraccional de urea lo cual podía explicar su uremia normal pese a estar cursando una caída del filtrado gomerular. Dicha excreción de urea elevada fue interpretada como secundaria a una diabetes insipida nefrogénica y una alteración en el recirculado intra-renal de la urea ambos producto de la pielonefritis aguda. Concluimos que la pielonefritis aguda en un paciente mono-reno puede presentarse con un patrón de insuficiencia renal aguda con uremia normal.

    Full Text Available 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. PHYSIOPATHOLOGY OF ACUTE RENAL FAILURE.NEW CLUES FOR AN OLD DILEMMA

    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.

  12. Comparison of renal toxicity after injection of CT contrast medium and MR contrast medium: change of renal function in acute renal failure rat models

    International Nuclear Information System (INIS)

    To determine renal toxicity through changes in renal function after the injection of CT and MRI contrast media into rats in which acute renal failure (ARF) was induced. To cause acute renal failure, the abdominal cavity of 110 male rats each weighing 250-300 gm was opened via a midline incision under anesthesia. Microvascular clamps were placed on both renal arteries and veins to completely block renal blood flow for 45 minutes, and were then removed, allowing blood flow to return to the kidneys. ARF, defined as a two-fold difference in the creatinine level before ARF and 48 hours after, was successfully induced in 60 of the rats. These were divided into two groups: one was injected with CT contrast medium and the other with MRI contrast medium. Each CT and MRI group was divided into a low dose (0.5 cc/kg, 0.2 ml/kg), standard dose (2 cc/kg, 0.8 ml/kg), and high dose (8 cc/kg, 3.2 ml/kg) sub-group; thus, there was a total of six groups with ten rats in each. Blood samples were obtained before ARF, 48 hours after, and 48 hours after contrast injection, and CT scanning and MRI were performed after blood sampling at 48 hours. In each group, creatinine levels 48 hours after contrast injection were compared by means of the ANOVA test. There were no significant differences in creatinine levels between the CT and MRI contrast medium groups (p=0.116), nor between the animals to which different doses of CT and MRI contrast medium, were administered. After both standard and high doses, CT and MRI provided good images. In rats in which acute renal failure was induced, renal function did not change according to whether CT or MRI contrast medium was injected. Thus, the two media induce similar levels of toxicity

    BACKGROUND Unexplained renal insufficiency combined with hepatic failure is a common problem encountered by clinicians. As with many disease processes involving multi-organ systems, reversible causes are usually not readily identifiable, and for many patients their health deteriorates rapidly. We present a rare cause of acute renal failure and hyperbilirubinemia occurring simultaneously, with leptospirosis presenting as Weil's disease. CASE REPORT A 53-year-old male presented to our clinic with complaints of anuria over the past two days. His symptoms started with dark urine, severe cramps in the thighs, and chills. The patient was a visitor to the United States from Guyana. Positive physical examination findings included mild tachycardia and hypotension, scleral icterus, and tenderness over abdomen, costovertebral angles, and thighs. The patient had a high white blood cell count, thrombocytopenia, renal/hepatic insufficiency, and an urinary tract infection (UTI). The patient was initially treated under the suspicion of acute kidney injury secondary to rhabdomyolysis and pyelonephritis. The patient continued to deteriorate with decreasing platelet counts, worsening renal function, hyperbilirubinemia, and respiratory distress, with no improvement with hemodialysis. Broad-spectrum antibiotics were administered, including doxycycline, due to a high suspicion of leptospirosis. The patient's condition drastically improved after initiation of doxycycline. On subsequent days, the patient's Leptospira antibody results were available, showing titers of more than 1:3200. Hemodialysis was discontinued as the patient started producing urine with improved kidney function. CONCLUSIONS As world travel becomes more economically feasible, we will continue to encounter foreign endemic diseases. Leptospirosis presenting as Weil's disease is a common cause of renal and hyperbilirubinemia in endemic areas. Often, as was the case for our patient where the time from presentation to acute

  14. Thrombotic thrombocytopenic purpura and myoglobinuric acute renal failure following radiation therapy in a patient with polymyositis and cervical cancer

    International Nuclear Information System (INIS)

    A 73-year-old woman was admitted to receive radiation treatment for uterine cervical cancer, however a complex series of events ensued, leading to death. She developed an acute exacerbation of polymyositis complicated by thrombocytopenic purpura, rhabdomyolysis and acute renal failure. Radiation therapy may have produced an immune disturbance leading to the acute exacerbation of polymyositis. Auto-immune-mediated endothelial damage might have triggered a series of events leading to thrombotic thrombocytopenic purpura. Rhabdomyolysis seemed to be the main cause of acute renal failure.

    Full Text Available The annual incidence is about 150 per million in the UK, but this figure is six times greater in the >80 years old group. Prerenal azotemia is considered as the most serious reason in community or hospital acquired acute renal failure (ARF. A 67-year-old middle age male was admitted to the hospital with a chief complaint of generalized weakness, volume depletion and dysuria. He has treated with metronidazole for diarrhoea caused by Clostridium difficile considered as the precipitating factor for the ARF. The patient has severe osteoarthritis and takes high dose non-steroidal anti-inflammatory drugs from the last two years. He also complains for obstructive sleep apnea (OSA and obesity. He has controlled hypertension was on lisinopril to control blood pressure. ARF is quite common, occurring in 80 million populations. Urinary obstruction should be excluded (a cause in around 5-10 of cases because this is readily reversible if it is diagnosed early. A renal US will be sufficient to identify obstruction in 95 of cases. Most cases of ARF are expected to pre renal failure/acute tubular necrosis (ATN 70-80%. Risk factor for development for at ATN are old age, drugs (non-steroidal anti-inflammatory drugs, gentamicin, sepsis, and chronic kidney disease and must be considered.

    Full Text Available Introduction. Acute renal failure (ARF develops in 33% of the patients with rhabdomyolysis. The main etiologic factors are alcoholism, trauma, exercise overexertion, and drugs. In this report we present a rare case of ARF secondary to probably donepezil-induced rhabdomyolysis. Case Presentation. An 84-year-old male patient was admitted to the emergency department with a complaint of generalized weakness and reduced consciousness for two days. He had a history of Alzheimer’s disease for one year and he had taken donepezil 5 mg daily for two months. The patient’s physical examination revealed apathy, loss of cooperation, and decreased muscle strength. Laboratory studies revealed the following: urea: 128 mg/dL; Creatinine 6.06 mg/dL; creatine kinase: 3613 mg/dL. Donepezil was discontinued and the patient’s renal function tests improved gradually. Conclusion. Rhabdomyolysis-induced acute renal failure may develop secondary to donepezil therapy.

    Enteropathy-associated T-cell lymphoma (EATCL) is a high grade, pleomorphic peripheral T-cell lymphoma usually with cytotoxic phenotypes. We describe a first case of patient with EATCL that is remarkable for its fulminant course and invasion of both kidneys manifested as acute renal failure. The patient was a 23 year old woman with a long history of celiac disease. She was presented with acute renal failure and enlarged mononuclear infiltrated kidneys. Diagnosis of tubuloi-nterstitial nephritis and polyserositis was confirmed with consecutive pulse doses of steroid therapy. After reco-very, she had disseminated disease two months later. Magnetic resonance imaging showed thickened intestine wall, extremely augmented kidneys, enlarged intra-abdominal lymph nodes with extra-luminal compression of common bile duct. Laparotomy with mesenterial adipous tissue and lymph glands biopsy was done. Consecutive pathophysiological and immunohistochemical analyses confirmed the diagnosis of EATCL: CD45RO+, CD43+,CD3+. The revision of renal pathophysiology sub-stantiated the diagnosis. The patient received chemotherapy,but unfortunately she died manifesting signs of pulmonary embolism caused by tumor cells.

    Phenazopyridine is a commonly used urinary analgesic available throughout the United States. Ingestion of large quantities can lead to methemoglobinemia, hemolytic anemia, jaundice, and acute renal failure. We report a case of a 78-year-old male with previously normal renal function who developed acute renal failure and jaundice without methemoglobinemia or hyperbilirubinemia after taking nearly 8 g of phenazopyridine over the course of 4 days. Initially presenting with oliguria, the urine output began to increase by day 2 of his admission, and the creatinine peaked 11 days after he began taking phenazopyridine, and he was discharged safely soon after. To our knowledge, this is the first such case of renal failure and jaundice without methemoglobinemia or hemolytic anemia in an adult patient with normal renal function. PMID:24711939

    Leptospirosis is an infectious disease caused by pathogenic leptospires and is characterized by a broad spectrum of clinical manifestations, varying from inappearent infection to fulminant, fetal disease. Eighty-five to 90% of leptospirosis infections are self-limiting. However, 5-10% of infection by L. interrogans can cause renal tubular damage, microvascular injury, acute renal failure (ARF), and interstitial nephritis. We studied 36 patients with leptospirosis. Twenty-seven (65%) cases of 36 patients had ARF. Fourteen (51%) had nonoliguric ARF. In thirteen (48%) oliguria appeared on the third or fourth days of hospitalization. Serum BUN, creatinine, serum bilirubine, ALT, AST, potassium and thrombocytopenia levels were higher in oliguric than nonoliguric patients (p 0.05). Thirteen patients (48%) needed in renal replacement therapy (RRT). 8 of them were treated by hemodialysis (HD) alone and 5 patients by HD in combination with hemoperfusion. Twenty-five patients (92%) recovered completely after 3-5 weeks. Two patients (7.4%) who had severe hepatorenal and hemorrhagic syndromes, died. We concluded that till now leptospirosis is actual problem for nephrologist in the developing countries because of very high percentage of renal disease, with good prognosis in patients without multiorgan failure and early treatment.

    Full Text Available Selenium (Se is an essential trace element in human and animal nutrition. It is also widely utilized in industrial processes. Reports of acute selenium toxicity in humans are rare. We report a case of a 23-year-old female who consumed about 100 mL of liquid selenite broth and presented with severe nausea, vomiting, abdominal pain, hematemesis and acute renal failure (ARF. The serum selenium level was significantly increased. Gastro-duodenoscopy revealed severe corrosive gastritis. Renal biopsy showed features of acute tubular necrosis (ATN, affecting primarily the proximal tubules. The patient was managed with gastric lavage, blood transfusions, infusion of fresh frozen plasma (FFP and platelet concentrates and hemo-dialysis. The patient was discharged five weeks after admission and her renal functions reco-vered completely by eight weeks after admission. She continues to be on regular follow-up for any possible sequelae of mucosal corrosive damage. This case highlights a case of selenium intoxication from selenite broth resulting in ARF and corrosive gastritis. The recovery was complete.

    Balantidium coli is the only ciliated protozoan which is known to infect human and nonhuman primates. Route of infection is faecal-oral route. It is actively motile and causes mostly asymptomatic infections, or it may develop dysentery which is similar to that which is caused by Entamoeba histolytica. Here, we are describing a case of an accidental finding of B.coli in the urine of a patient who presented with acute renal failure, based on its characteristic morphology and motility which were seen on light microscopy. This is the third case of Urinary Balantidiosis which has been reported from India. PMID:24995185

    The objective of this study was to evaluate the effect of the surgical technique on postoperative renal function during the first week after liver transplantation (OLT). We performed a retrospective study of 184 consecutive OLT. Criteria for acute renal failure were: serum creatinine >1.5 mg/dL, an increase by 50% in the baseline serum creatinine, or oliguria requiring renal replacement therapy. The distribution of patients according to the surgical technique was: standard (n=84), venovenous bypass (n=20), and piggyback (n=80). Other variables analyzed were: intraoperative requirement for blood products, treatment with adrenergic agonists, intraoperative complications, and postreperfusion syndrome. Univariate analysis showed the following parameters to be significantly related to postoperative renal failure: intraoperative fresh frozen plasma and cryoprecipitate requirements, intraoperative complications, postreperfusion syndrome, need for noradrenaline or dobutamine, standard surgical technique versus piggyback (39% vs 18%, P20 U cryoprecipitate requirement (OR=1.04, P=.01). In conclusion, compared with the piggyback technique, the standard surgical technique appears to be an independent risk factor for postoperative acute renal failure. When venovenous bypass is used in patients who do not tolerate trial clamping of inferior vena cava, it does not reduce the incidence of postoperative renal failure. Finally, the piggyback technique significantly reduces the probability of acute renal failure after liver transplantation.

    Full Text Available Objectives To evaluate the result of treatment of acute renal failure (ARF in patients after cardiac surgery. Methods The clinical data of 54 cases admitted to the hospital from Jan. 2004 to Jan. 2014 and suffered from ARF after cardiac surgery were retrospectively analyzed. Among 54 cases, there were 35 males and 19 females, aged from one month to 79 years with a median of 52 years. The surgical procedures included coronary artery bypass grafting (CABG, 10 cases, valve surgery (22 cases, combined CABG and valve surgery (4 cases, operation on aorta (14 case, and radical correction of Fallot tetralogy (4 cases. After the operations mentioned above, 50 patients received continuous renal replacement therapy (CRRT, and 4 patients received peritoneal dialysis. Results Nine patients died, the mortality rate was 16.7%. Exploratory hemostasis by thoracotomy was performed in 8 patients, and extubation failure occurred in 4 cases. Of the 9 non-survivors, 6 died from multiple organ failure (MOF, 2 died from cerebral hemorrhage, and one died from acute respiratory failure. Serum creatinine (SCr and blood urea nitrogen (BUN levels declined obviously after CRRT and peritoneal dialysis (P<0.05, and all the patients were shown to have stable hemodynamics in the course of treatment, and no hemorrhage or embolism occurred. Conclusions ARF after cardiac surgery should be detected early and treated in time. CRRT and peritoneal dialysis are safe, convenient and effective procedures, and may decrease the mortality rate in patients with ARF after cardiac surgery. DOI: 10.11855/j.issn.0557-7402.2015.04.13

    A series of 46 patients with obstructive disease of the bile ducts complicated by acute renal failure (ARF) is presented. The patients exhibited obstructive jaundice with prevalence of conjugated bilirubine. In 80% of the cases biliary obstruction was associated with cholangitis. Disturbances of the liver function (from mild cholestasis to biliary cirrhosis) were also present. The renal damage was due to biliary disorders and was either present on admission (33 cases) or developed postoperatively (13 cases). Most of the patients presented nonoliguric ARF as well as poor perfusion resulting from decreased circulating blood volume (dehydration and electrolyte loss). Among the criteria used to determine the type of ARF, the urinary/plasma creatinine ratio less than 10 and urinary/plasma osmolarity ratio less than 1.1 were the most valuable. Management of ARF by dialysis alone was not satisfactory. Attention is called to the surgical treatment of the biliary disorder as being essential to prognosis. Patients not treated by radical surgery died in proportion of 87 to 100%. From the rest of 18 patients in whom the operation provided an adequate biliary drainage, in 15 the renal function was restored and 12 survived. Better prognosis in these patients was dependent not only on the ability to cure the cholestasis and infection, but on the early surgical treatment. The ultimate prognosis depends on the improvement of the liver function.

    Plastibell is one of the three most common devices used for neonatal circumcision in the United States, with a complication rate as low as 1.8%. The Plastibell circumcision device is commonly used under local anesthesia for religious circumcision in male neonates, because of cosmetic reasons and ease of use. Occasionally, instead of falling off, the device may get buried under the skin along the shaft of the penis, thereby obstructing the normal flow of urine. Furthermore, the foreskin of neonates is highly vascularized, and hence, hemorrhage and infection are possible when the skin is cut. Necrosis of penile skin, followed by urethral obstruction and renal failure, is a serious surgical mishap requiring immediate corrective surgery and medical attention. We report a case of fulminant urosepsis, acute renal failure, and pyelonephritis in a 4-day-old male neonate secondary to impaction of a Plastibell circumcision device. Immediate medical management was initiated with fluid resuscitation and mechanical ventilation; thereby correcting life threatening complications. Pediatricians and Emergency Department physicians should be cognizant of the complications from Plastibell circumcision device in order to institute appropriate and timely management in neonates.

    Objective: To report a comparative clinical and histopathological study on oliguric and non-oliguric acute renal failure (ARF) in malaria. Method: 311 consecutive cases of malaria out of which 74 (23.79%) had ARF as per WHO criteria were conducted. Mean age was 32.58 (range 15-60 years) and male: female was 2:1. Result: Most of the cases developed ARF within 10 d of onset. 18 cases (11 falciparum, 2 mixed, 5 vivax) presented with oliguric and 56 (41 falciparum, 6 mixed, 9 vivax) with non-oliguric renal failure. Associated major manifestations were jaundice (75.68%), cerebral malaria (41.89%), bleeding manifestations (32.43%), severe anemia (27.03%), hypotension (25.68%), multi-organ failure (18.92%), severe thrombocytopenia (12.16%), and ARDS (8.11%). Kidney biopsy (n=20) showed acute tubular necrosis (n=7), Mesangioproliferative glomerulonephritis (n=4) or both (n=9). Hemodialysis was done in 8 cases of oliguric renal failure out of which 4 survived (average no. of session 2.9). Conclusion: Most of the cases recovered within 3 weeks. Total mortality was 28.38% (n=21) and mortality was more in oliguric renal failure (72.22%) as compare to non-oliguric renal failure (14.29%).

    Thirty neonates with acute renal failure were studied, 27 of whom died (90%) including nine of 12 treated by peritoneal dialysis. Three main aetiological groups were identified. Septicaemia was a principal cause of late onset acute renal failure, with an incidence equal to that of serious perinatal disorders. It is recommended that tolazoline should be used with caution in the treatment of hyperkalaemia as it may have a role in the aetiology of acute renal failure, the incidence of which is i...

    Full Text Available Introduction: The posterior reversible encephalopathy syndrome (PRES is a neurological entity characterized by magnetic resonance imaging (MRI evidence of bilateral subcortical edema in the occipital regions of the brain. Case report: We report the case of a female patient with AIDS, pulmonary aspergillosis, CMV infection, and acute renal failure due to Clostridium difficile diarrhea. Her clinical course was complicated by seizures and hypertension. MRI findings were consistent with PRES. The patient was treated with anticonvulsants and antihypertensive agents with clinical improvement. Discussion and conclusions: Few cases of PRES in HIV-infected patients have been described, and it is not clear whether HIV infection is a predisposing factor for this syndrome. The article reviews the literature on PRES in HIV and discusses the role of HIV-associated endothelial damage in the pathogenesis of this syndrome.

    Background Infants in some areas of China developed urinary lithiasis after being fed with powdered milk that was tainted with melamine in 2008 and very small proportion of the infants developed acute renal failure caused by urinary tract calculus obstruction. The aim of this article was to summarize clinical characteristics, diagnosis and treatment of infants with urinary calculus and acute renal failure developed after being fed with melamine tainted formula milk.Methods Data of infant patients with urinary calculus and acute renal failure due to melamine tainted formula milk admitted to the Beijing Children's Hospital Affiliated to the Capital Medical University and the Xuzhou Children's Hospital in 2008 were used to analyze the epidemiological characteristics, clinical manifestations, imaging features as well as effects of 4 types of therapies.Results All the 34 infants with urinary calculus were complicated with acute renal failure, their blood urea nitrogen (BUN) was (24.1±8.2) mmol/L and creatinine (CO was (384.2±901.2) μmol/L. The chemical analysis on the urinary calculus sampled from 15 of the infants showed that the calculus contained melamine and acidum uricum. The time needed for the four types of therapies for returning Cr to normal was (3.5±1.9) days for cystoscopy group, (2.7±1.1) days for lithotomy group, (3.8±2.3) days for dialysis group, and (2.7±1.6) days for medical treatment group, which had no statistically significant difference (P=0.508). Renal failure of all the 34 infants was relieved within 1 to 7 days, averaging (3.00±1.78) days.Conclusions Melamine tainted formula milk may cause urinary calculus and obstructive acute renal failure. It is suggested that firstly the patients with urinary calculus complicated with acute renal failure should be treated with dialysis or medication to correct electrolyte disturbance, in particular hyperkalemia, and then relieve the obstruction with available medical and surgical methods as soon as

    During posttransplant acute renal failure (ARF), the diagnosis of allograft rejection constitutes a major problem. We evaluated the value of Doppler ultrasonography in identifying grafts at risk of rejection during ARF. In 184 recipients of a renal allograft, Doppler examinations were performed on the first and fifth postoperative day. Doppler spectra were quantitatively analyzed with a user-written computer program. Doppler findings were not used in clinical decision making. ARF was defined as a diuresis cadaveric grafts (n = 123), while living related donor grafts (n = 20) showed a lower RI (0.55 +/- 0.07; P 4 days (n = 24), RI was not significantly different (0.63 +/- 0.07 vs. 0.68 +/- 0.15; NS). However, the acceleration time of the systolic deflection of the spectrum waveform (Tmax) was shorter in grafts with ARF > 4 days (86 +/- 47 msec vs. 128 +/- 39 msec; P 4 days (n = 24) showed a Tmax or = 90 msec, only 2 rejections occurred (negative predictive value, 13/15 = 87%). For the RI (> 0.85), positive predictive value was 4/5 = 80% and negative predictive value (RI identification of patients at risk for rejection and in the timing of allograft biopsy during ARF. Persistently short Tmax values on the fifth day after transplantation perform better in identifying grafts at risk of rejection than high RI values.

    Renal failure is a frequent complication of multiple myeloma (MM). Recently, the combination of lenalidomide-dexamethasone has become one of the cornerstone regimens for the treatment of MM. Impairment of renal function exacerbation is a rare, but potential, complication of lenalidomide therapy in plasma cell dyscrasias. We present two patients who developed exacerbation of renal function during their first cycle of therapy with lenalidomide. In the first case, we present a 76-year-old-male with MM and impaired renal function, who declined two weeks after initiation of second-line therapy with lenalidomide. His renal functions improved after discontinuation of lenalidomide and with supportive care. In the second case, we describe a 61-year-old woman who was started on lenalidomide for relapsed MM and admitted to intensive care unit three weeks later due to severe renal failure. Despite intensive supportive care, her renal function deteriorated even more and she died. We conclude that renal failure is an uncommon, but serious, potential complication of lenalidomide therapy in plasma cell dyscrasias, particularly MM. Close monitoring of renal function is clearly recommended during this treatment.

  12. Renal Cortical Lactate Dehydrogenase: A Useful, Accurate, Quantitative Marker of In Vivo Tubular Injury and Acute Renal Failure.

    Richard A Zager

    Full Text Available Studies of experimental acute kidney injury (AKI are critically dependent on having precise methods for assessing the extent of tubular cell death. However, the most widely used techniques either provide indirect assessments (e.g., BUN, creatinine, suffer from the need for semi-quantitative grading (renal histology, or reflect the status of residual viable, not the number of lost, renal tubular cells (e.g., NGAL content. Lactate dehydrogenase (LDH release is a highly reliable test for assessing degrees of in vitro cell death. However, its utility as an in vivo AKI marker has not been defined. Towards this end, CD-1 mice were subjected to graded renal ischemia (0, 15, 22, 30, 40, or 60 min or to nephrotoxic (glycerol; maleate AKI. Sham operated mice, or mice with AKI in the absence of acute tubular necrosis (ureteral obstruction; endotoxemia, served as negative controls. Renal cortical LDH or NGAL levels were assayed 2 or 24 hrs later. Ischemic, glycerol, and maleate-induced AKI were each associated with striking, steep, inverse correlations (r, -0.89 between renal injury severity and renal LDH content. With severe AKI, >65% LDH declines were observed. Corresponding prompt plasma and urinary LDH increases were observed. These observations, coupled with the maintenance of normal cortical LDH mRNA levels, indicated the renal LDH efflux, not decreased LDH synthesis, caused the falling cortical LDH levels. Renal LDH content was well maintained with sham surgery, ureteral obstruction or endotoxemic AKI. In contrast to LDH, renal cortical NGAL levels did not correlate with AKI severity. In sum, the above results indicate that renal cortical LDH assay is a highly accurate quantitative technique for gauging the extent of experimental acute ischemic and toxic renal injury. That it avoids the limitations of more traditional AKI markers implies great potential utility in experimental studies that require precise quantitation of tubule cell death.

    Full Text Available Acute renal failure (ARF is reported in some severe forms of malaria such as black water fever (BWF. It is associated with a high mortality rate and can be managed effectively with adequate renal replacement. A prospective survey of children with dark urine after a malarial infection with Plasmodium falciparum was coupled with a chart review study of patients managed in the past 11 years in the Pediatrics′ Kinshasa University Hospital. Eighty-nine cases of ARF were identified, but data from only 63 patients were available, of whom 44 (69.8% had severe malaria (39 with BWF and 5 with cerebral malaria. The mean age of the patients was 8.2 ± 1.73 years. Of the 39 cases of BWF, an association with quinine ingestion was observed in 32 children (82%. Urea and creatinine levels were elevated in all cases (135.4 ± 88.2 and 3.83 ± 2.81 mg/dL, respectively. Oligo-anuria was observed in 44.4%, severe metabolic acidosis (bicarbonate <15 mEq/L in 61.5% and hyponatremia (<130 mEq/L in 33.3%. Peritoneal dialysis was required in 36 patients, including 20 with BWF. The remaining patients were managed with conservative treatment. Twenty-eight children (44.4%, including 20 on dialysis, fully recovered and 14 died (22.2%, including eight cases of BWF. Our study suggests that ARF is commonly associated with BWF in Congolese children. Elevated urea and creatinine and severe metabolic acidosis were observed more often than other clinical/metabolic disturbances. Severe renal impairment remains a significant complication with a high mortality rate in low-resource settings.

  14. Collagen XVIII/endostatin expression in experimental endotoxemic acute renal failure

    Full Text Available Acute renal failure (ARF is a frequent complication of Gram-negative sepsis, with a high risk of mortality. Lipopolysaccharide (LPS-induced ARF is associated with hemodynamic changes that are strongly influenced by the overproduction of nitric oxide (NO through the cytokine-mediated up-regulation of inducible NO synthase. LPS-induced reductions in systemic vascular resistance paradoxically culminate in renal vasoconstriction. Collagen XVIII is an important component of the extracellular matrix expressed in basement membranes. Its degradation by matrix metalloproteases, cathepsins and elastases results in the formation of endostatin, claimed to have antiangiogenic activity and to be a prominent vasorelaxing agent. We evaluated the expression of endostatin/collagen XVIII in an endotoxemic ARF model. ARF was induced in C57BL/6 mice by intraperitoneal injection of LPS (10 mg/kg followed by sacrifice 4 and 12 h later. Kidney tissue was the source of RNA and protein and the subject of histological analysis. As early as 4 h after LPS administration, blood urea, creatinine and NO levels were significantly increased compared to control. Endostatin/collagen XVIII mRNA levels were 0.71 times lower than sham-inoculated mice 4 h after LPS inoculation, returning to normal levels 12 h after LPS inoculation. Immunohistological examination revealed that acute injury caused by LPS leads to an increase of endostatin basement membrane staining in association with the decrease of CD31 endothelial basement membrane staining. These results indicate that in the early phase of endotoxemic ARF the endostatin levels were not regulated by gene expression, but by the metabolism of collagen XVIII.

    Full Text Available We report on 4 cases of abdominal compartment syndrome complicated by acute renal failure that were promptly reversed by different abdominal decompression methods. Case 1: A 57-year-old obese woman in the post-operative period after giant incisional hernia correction with an intra-abdominal pressure of 24 mm Hg. She was sedated and curarized, and the intra-abdominal pressure fell to 15 mm Hg. Case 2: A 73-year-old woman with acute inflammatory abdomen was undergoing exploratory laparotomy when a hypertensive pneumoperitoneum was noticed. During the surgery, enhancement of urinary output was observed. Case 3: An 18-year-old man who underwent hepatectomy and developed coagulopathy and hepatic bleeding that required abdominal packing, developed oliguria with a transvesical intra-abdominal pressure of 22 mm Hg. During reoperation, the compresses were removed with a prompt improvement in urinary flow. Case 4: A 46-year-old man with hepatic cirrhosis was admitted after incisional hernia repair with intra-abdominal pressure of 16 mm Hg. After paracentesis, the intra-abdominal pressure fell to 11 mm Hg.

    Full Text Available Cocaine has been associated with known adverse effects on cardiac, cerebrovascular and pulmonary systems. However, the effect of cocaine on other organs has not been extensively reported. A middle age man presented with abdominal pain and nausea after inhalation of crack cocaine. On admission, he was found to be hypertensive and tachycardic. Physical examination revealed mild abdominal tenderness without rebound. Laboratory investigations were significant for acute kidney failure with elevated serum creatinine (3.72 mg/dL, thrombocytopenia (platelet count 74,000/UL, elevated alanine and aspartate transaminases (ALT 331 U/L; AST 462 U/L and elevated creatine phosphokinase (CPK 5885 U/L. Urine toxicology screening solely revealed cocaine. A clinical diagnosis of cocaine toxicity was made and patient was admitted to the intensive care unit because of multi organ failure. Despite downward trending of liver enzymes during the hospital course, he continued to have residual renal insufficiency and a low platelet count at the time of discharge. In a patient with history of recent cocaine use presenting with these manifestations, cocaine itself should be considered as a likely cause.

    Due to a combination of ingested ethanol and inhaled trichloroethylene (Tri) a 28 year old man developed toxic hepatitis and acute oliguric renal failure, both of which had a favorable evolution. Tri has been described as a cause of hepatic disfunction and acute renal failure due to acute tubular necrosis, although some of the cases described are controversial, because Tri was either contaminated by other dissolvents or could not be proven pure, with the exception of one case. In many there was ethanol ingestion. The Tri inhaled by our patient was found to contain less than 1% of carbon tetrachloride (C-Tchl). This would suggest the C-Tchl to be responsible for the clinical picture although the combination Tri/ethanol cannot be discarded as the causal agent, due to the small amount of contaminant present.

    The clinical course and medical treatment of patients with congestive heart failure (CHF) complicating acute myocardial infarction (AMI) are not well established, especially in patients with concomitant renal dysfunction. We performed a retrospective analysis of the prospective Korean Acute Myocardial Infarction Registry to assess the medical treatments and clinical outcomes of patients with CHF (Killip classes II or III) complicated by AMI, in the presence or absence of renal dysfunction. Of 13,498 patients with AMI, 2769 (20.5%) had CHF on admission. Compared to CHF patients with preserved renal function, in-hospital mortality and major adverse cardiac events were increased both at 1 month and at 1 year after discharge in patients with renal dysfunction (1154; 41.7%). Postdischarge use of aspirin, betablockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, or angiotensin II receptor blockers and statins significantly reduced the 1-year mortality rate for CHF patients with renal dysfunction; such reduction was not observed for those without renal dysfunction, except in the case of aspirin. Patients with CHF complicating AMI, which is accompanied by renal dysfunction, are at higher risk for adverse cardiovascular outcomes than patients without renal dysfunction. However, they receive fewer medications proven to reduce mortality rates.

  20. A retrospective characterization of worsening renal function in patients with acute decompensated heart failure receiving nesiritide

    Full Text Available Nesiritide is approved by Food and Drug Administration (FDA for the treatment of patients with acute decompensated heart failure (ADHF due its ability to rapidly reduce cardiac filling pressures and improve dyspnea. Numerous studies have shown that renal dysfunction is associated with unfavorable outcomes in patients with heart failure. In addition, there have been reports suggesting that nesiritide may adversely affect renal function and mortality. Objective: The purpose of this retrospective analysis was to assess the effect of dose and duration of nesiritide use and the dose and duration of diuretic therapy on worsening renal function and increased in-hospital mortality in this patient population.Methods: Seventy-five patients who were hospitalized for ADHF and who were treated with nesiritide for at least 12 hours were reviewed retrospectively. Results: The mean increase in SCr was 0.5 mg/dL (range 0 – 4.4 mg/dL. Thirty-six percent of patients (27/75 met the primary endpoint with an increase in SCr>0.5 mg/dL. Treatment dose and duration of nesiritide did not differ between those patients who had an increase in SCr>0.5 mg/dL and those who did not (p=0.44 and 0.61. Concomitant intravenous diuretics were used in 85% of patients with an increase in SCr >0.5 mg/dL compared to 90% of patients without an increase in SCr>0.5 mg/dL (p=0.57. The in-hospital mortality rate was also higher at 35% in those patients with an increase in creatinine >0.5 mg/dL compared to 11% in those without (p=0.01. Conclusion: Nesiritide was associated with an increase in SCr > 0.5 mg/dL in approximately one-third of patients. The increase occurred independently of dose, duration of nesiritide therapy, blood pressure changes, and concomitant intravenous diuretic use. However, the increase in SCr was associated with an increase in hospital stay and in hospital mortality consistent with previous reports in the literature.

    Background Assessment of perfusion in the early period of acute renal failure (ARF) is important,and can not be made by conventional ultrasound.The aim of this study was to prospectively test in a rabbit ARF model whether real-time contrast-enhanced ultrasound (CEUS) can quantitatively evaluate the hemodynamic changes of renal cortex in the early period.Methods The model of ARF was induced in 30 healthy New Zealand white rabbits (2.5-3.0 kg),by intramuscular injection of 50% glycerin solution (12 ml/kg).CEUS were performed on right kidneys before,6 and 24 hours after glycerin injection.CEUS quantitative indexes were measured in renal cortex using QLAB software.Comparisons between different stages were performed using paired t test.The sensitivity of CEUS in diagnosing ARF was compared with blood serum urea nitrogen (BUN),serum creatinine (SCr) level and color Doppler flow imaging (CDFI).Results Among quantitative indexes,time to peak (TTP) and area under curve (AUC) increased significantly from (5.86±2.57) seconds and (124.4±46.7) dB.s before glycerin injection to (7.66±2.05) seconds and (288.1±64.9) dB.s 6 hours after injection (P <0.05).Slope rate of ascending curve (A) and descending curve (α) decreased slightly from (3.00±1.22) dB/s and (0.19±0.15) 1/s to (2.80±1.45) dB.s and (0.09±0.02) 1/s (P <0.05).Twenty-four hours later,only AUC increased significantly from (124.4±46.7) dB.s to (466.2±52.2) dB.s (P<0.05).Conclusion Quantitative indexes of CEUS might be useful in predicting the hemodynamic changes of renal cortex in the early six hours of ARF model.

    Renal failure remains a serious cause of mortality in Yemen. Our region has 1.25 million population and our hospital is the central hospital, which has a nephrology department and performs dialysis for the region. Between January 1998 and December 2002, we admitted 547 patients; including children, with acute renal failure (ARF) and chronic renal failure (CRF). CRF was observed in 400 patients, an incidence of 64 per million per year and a prevalence of 320 per million. ARF occurred in 147 persons with an incidence of 23.5 per million per year and a prevalence of 117.5 patients per million. Of all patients, 72% were adults (age range, 20-60 years) with a male preponderance. As a tropical country, malaria (27.9%), diarrhea (13.6%), and other infectious diseases were the main causes. Next most common were obstructive diseases causing CRF and ARF (26.8% and 12.9%, respectively), mainly urolithiasis, Schistosomiasis, and prostatic enlargement. However the cause of CRF in 57.5% of patients was unknown as most persons presented late with end-stage disease (64.7%), requiring immediate intervention. Other causes, such as hepatorenal syndrome, snake bite, diabetes mellitus, and hypertension, showed low occurrence rates. Patients presented to the hospital mostly in severe uremia and without a clear history of prior medications. The major findings were vomiting, acidosis, and hypertension with serum creatinine values ranging between 2.8-45 mg/dL (mean value, 13.4 mg/dL). Anemia was observed in 80.4% of CRF versus 62.6% of ARF patients. Hypertension prevalence was 65.5% among CRF patients, of whom 25% were in hypertensive crisis, whereas among ARF the prevalence was only 26.5%. PMID:15350475

    Sunitinib is a multiple tyrosine kinase receptors inhibitor that is approved for the treatment of advanced renal cell carcinoma. Amongst its targets are fetal liver tyrosine kinase receptor 3 (FLT 3) and vascular endothelial growth factor receptor (VEGFR). Renal toxicity has not been reported from the trials, but several patients have been reported to develop a pre-eclampsia-like syndrome. We report the first case of acute tubular necrosis in a patient with multiple myeloma following treatment with sunitinib.

    To clarify the pathophysiologic role of apoptosis in acute renal failure (ARF), we examined whether the attenuation of cisplatin-induced ARF is associated with the change in the degree of apoptotic cell death. The administration of cisplatin (CDDP) (6 mg/kg body weight) in rats induced ARF at day 5, as manifested by a significant increase in serum creatinine (Scr) and tubular damage. CDDP-induced apoptotic cell death was confirmed by electron microscopic examination, agarose gel electrophoresis, and increased cells positive for TaT-mediated deoxyuridine triphosphate nick-end labeling (TUNEL) in the outer medulla of the kidney. Treatment with dimethylthiourea (DMTU)--a scavenger of hydroxyl radicals--or glycine abrogated CDDP-induced increases in Scr, the tubular damage score, and the number of TUNEL-positive cells. Pretreatment with uranyl acetate (UA) induced a significant expression of Bcl-2 in the kidney and ameliorated CDDP-induced increases in Scr, the tubular damage score, and TUNEL-positive cells in the outer stripe of the outer medulla. Our findings indicate (1) that the attenuation of CDDP-induced ARF was associated with less apoptotic cell death and (2) that the induction of the anti-apoptotic protein Bcl-2 attenuated apoptosis and tubular damage. Our results suggest that apoptotic cell death may play an important role in the development of cisplatin-induced ARF. PMID:10595794

    Aim: To study the effect of selective interleukin-1 β-converting enzyme (ICE,caspase-1) inhibitor on ischemic acute renal failure (ARF). Methods: Mouse models of ischemic ARF were treated with the specific ICE inhibitor AC-YVAD-CMK.A renal function assay and renal morphological studies were employed to estimate the renal protective effect of AC-YVAD-CMK. The survival rate of mouse models was also analyzed by a time series test. Furthermore, renal ICE activity,mature interleukin-18 (IL-18) protein expression and interferon-γ (IFN-γ) mRNA expression were also detected by fluorescent enzyme-linked immunosorbent assay (ELISA), ELISA, and semi-quantitative reverse transcription-polymerase chain reaction, respectively. Results: The levels of blood urea nitrogen (BUN) and serum creatinine (Scr) increased remarkably in the model controls compared with the sham-operated groups (P<0.01). Typical renal tubular necrosis was found in the model controls. Renal ICE activity, mature IL-18 protein expression, and IFN-γmRNA expression were also increased significantly in the model controls compared with the sham-operated groups. The levels of BUN and Scr in the AC-YVAD-CMK therapy group were decreased significantly compared with the untreated model controls (P<0.01). Renal tubulointerstitial lesion was also attenuated significantly (P<0.05). AC-YVAD-CMK therapy alleviated the clinical features of ARF, and increased the survival rate (P<0.01). Furthermore, AC-YVADCMK therapy also decreased ICE activity, mature IL-18 protein expression, and IFN-γ mRNA expression in renal tissue (P<0.05). Conclusion: The selective ICEinhibitor AC-YVAD-CMK can effectively protect the kidney from acute ischemic lesions. This protective effect is associated with decreased renal ICE activity and suppressed IL- 18 maturation and IFN-γ mRNA transcription.

    Full Text Available Objective To evaluate the stability, safety and efficacy of mobile blood purification system in the treatment of acute renal failure dog model in the field environment. Methods The acute renal failure model was established in 4 dogs by bilateral nephrectomy, which was thereafter treated with the mobile blood purification system. The evaluation of functional index of the mobile blood purification system was performed after a short-time (2 hours and conventional (4 hours dialysis treatment. Results The mobile blood purification system ran stably in the field environment at a blood flow of 150-180ml/min, a dialysate velocity of 2000ml/h, a replacement fluid velocity of 2000ml/h, and ultrafiltration rate of 100-200ml/h. All the functions of alarming system worked well, including static upper limit alarm of ultrafiltration pressure (>100 mmHg, upper limit alarm of ambulatory arterial pressure (>400mmHg, upper limit alarm of ambulatory venous pressure (>400mmHg, bubble alarm of vascular access, bubble alarm during the infusion of solutions, pressure alarm at the substitution pump segment and blood leaking alarm. The vital signs of the 4 dogs with acute renal failure kept stable during the treatment. After the treatment, a remarkable decrease was seen in the levels of serum urea nitrogen, creatinine and serum potassium (P0.05. Conclusions The mobile blood purification system runs normally even in a field environment. It is a flexible and portable device with a great performance in safety and stability in the treatment of acute renal failure. DOI: 10.11855/j.issn.0577-7402.2013.12.15

    Abstract Background Because of the rapid growth in elderly population, polypharmacy has become a serious public health issue worldwide. Although acute renal failure (ARF) is one negative consequence of polypharmacy, the association between the duration of polypharmacy and ARF remains unclear. We therefore assessed this association using a population-based database. Methods Data were collected from the Taiwan National Health Insurance Research Database (NHIRD) from 2003 through 2006.

    2011-08-01

    Full Text Available We report the case of a 65-year-old Caucasian woman who experienced two separate episodes of acute renal failure within an 18-month period, both requiring emergency admission and complicated treatment. Each episode was precipitated by hypovolaemia from intestinal fluid losses, but from two rare and independent pathologies. Her first admission was attributed to community-acquired Clostridium difficile-associated diarrhoea (CDAD and was treated in the intensive therapy unit. She returned 18 months later with volume depletion and electrolyte disturbances, but on this occasion a giant hypersecretory villous adenoma of the rectum (McKittrick-Wheelock syndrome was diagnosed following initial abnormal findings on digital rectal examination by a junior physician. Unlike hospital-acquired C. difficile, community-acquired infection is not common, although increasing numbers are being reported. Whilst community-acquired CDAD can be severe, it rarely causes acute renal failure. This case report highlights the pathological mechanisms whereby C. difficile toxin and hypersecretory villous adenoma of the rectum can predispose to acute renal failure, as well as the values of thorough clinical examination in the emergency room, and early communication with intensivist colleagues in dire situations.

    Abstract An independent association between acute renal failure(ARF)and intra-abdominal hypertension(IAH)after liver transplantation has not been established previously.The aim of this retrospective study was to understand the role of IAH as an independent risk factor for ARF in the early postoperative period.This study involved 62 subjects who underwent liver transplantation.Intra-abdominal pressure (IAP)was measured in the first three days after surgery by using the urinary bladder technique.An IAP of at least 20 mmHg per day was defined as IAH.Clinical parameters between group IAH and group NO-IAH were compared in terms of the incidence of ARF,blood creatinine levels,blood urea nitrogen (BUN)levels,urine volume per hour and glomerular filtration gradient(GFG).Hemodynamic variations were recorded in the first three postoperative days between group ARF and group NO-ARF.The perioperative suspected risk factors of ARF were determined for statistical evaluation using correlation coefficients and logistic regression analysiIn group IAH.45.8%patients developed ARF as against 7.9in group NO-IAH;GFG was significantly lower at 0-72 h after surgery;and blood creatinine levels,BUN levels,urine volume per hour were significantly different at 24-72 h after surgery compared with group NO-IAH.The patients with ARF were not significantly difierent from those without ARF in terms of central venous pressure,pulmonary artely pressure and mean arterial pressure(MAP) in the first three postoperative days despite a significant increase in heart rate at 24-72h after operation.Postoperative IAH,intraoperative MAP and intraoperative blood transfusion volume of more than 15 U were found to be independent risk factors for ARF.IAH impaired renal function and was an independent risk factor for ARF after liver transplantation.Routine measurement should be taken to monitor IAP every eight hours postoperatively.

    Studies were performed to examine the effect of saline loading on uranium-induced acute renal failure (ARF) in rats. Forty-eight hours after the i.v. injection of uranyl acetate (UA, 5 mg/kg), inulin clearance rate (Cin) decreased to approximately 43% of the control value in water drinking rats (P less than 0.005). Animals receiving continuous isotonic saline infusion following UA showed higher urine flow and Cin (60% of control, P less than 0.01), and lessened intratubular cast formation when compared with water-drinking ARF rats. A short-term saline infusion following UA did not attenuate the decline in Cin (43% of control). An inverse relationship was found between Cin and the number of casts (r = -0.75, P less than 0.01). Multiple regression analysis showed that standardized partial regression coefficient is statistically significant between Cin and cast formation (-0.69, P less than 0.05), but not between Cin and tubular necrosis (-0.07, P greater than 0.05). Renin depletion caused by DOCA plus saline drinking did not attenuate the decline in Cin in ARF (47% of control). No significant difference was found in urinary uranium excretion between water-drinking and saline-infused ARF rats. The findings suggest that continuous saline infusion following UA attenuates the decline in Cin in ARF rats; and that this beneficial effect of saline loading is associated with lessened cast formation rather than with suppressed renin-angiotensin activity or enhanced urinary-uranium excretion.

    Full Text Available HELLP is an acronym for hemolysis, elevated liver enzymes and low platelets count, affecting 0.2–12% of all pregnancies or 4–12% of those with preeclampsia. The maternal mortality reported from the literature is up 4% due to disseminated intravascular coagulation, placental abruption, acute renal failure, eclampsia, and cerebral hemorrhage. A 20 year old, G2P1, at 36 weeks of gestation, was referred to our hospital because of postictal coma state with bilateral mydriasis and epistaxis due to repeated antepartum eclamptic fits. Elevated blood pressure level 170/110 mmHg was accompanied with massive proteinuria. Cesarean section was performed and female newborn were delivered. Laboratory findings were characteristic of preeclampsia, HELLP syndrome and renal failure. The patient developed an intraventricular hematoma and an intracerebral hemorrhage with subarachnoid one, which were not suitable to neurosurgical treatment. The patient died from refractory hemolytic anemia, spontaneous bleeding of multiple organs, renal failure and intracranial hemorrhage. Preeclampsia, HELLP syndrome, and acute fatty liver of pregnancy might overlap and be associated with potentially fatal complications, including intracranial hemorrhage, as in the present case. Early detection and diagnosis are crucial to ensure appropriate management and treatment success.

    Free radical-mediated injury releases proinflammatory cytokines and activates innate immunity. It has been suggested that the early innate response and the ischemic tissue damage play roles in the development of adaptive responses, which may lead to acute kidney rejection. Various durations of hypothermic kidney storage before transplantation add to ischemic tissue damage. The final stage of ischemic injury occurs during reperfusion that develops hours or days after the initial insult. Repair and regeneration processes occur together with cellular apoptosis, autophagy and necrosis and a favorable outcome is expected if regeneration prevails. Along the entire transplantation time course, there is a great demand for novel immune and nonimmune injury biomarkers. The use of these markers can be of great help in the monitoring of kidney injury in potential kidney donors, where acute kidney damage can be overlooked, in predicting acute transplant dysfunction during the early post-transplant periods, or in predicting chronic changes in long term followup. Numerous investigations have demonstrated that biomarkers that have the highest predictive value in acute kidney injury include NGAL, Cystatin C, KIM-1, IL-18, and L-FABP. Most investigations show that the ideal biomarker to fulfill all the needs in renal transplant has not been identified yet. Although, in many animal models, new biomarkers are emerging for predicting acute and chronic allograft damage, in human allograft analysis they are still not routinely accepted and renal biopsy still remains the gold standard.

  17. Use of Renal Replacement Therapy May Influence Graft Outcomes following Liver Transplantation for Acute Liver Failure: A Propensity-Score Matched Population-Based Retrospective Cohort Study.

    Directory of Open Access Journals (Sweden)

    Stephen R Knight

    Full Text Available Acute kidney injury is associated with a poor prognosis in acute liver failure but little is known of outcomes in patients undergoing transplantation for acute liver failure who require renal replacement therapy.A retrospective analysis of the United Kingdom Transplant Registry was performed (1 January 2001-31 December 2011 with patient and graft survival determined using Kaplan-Meier methods. Cox proportional hazards models were used together with propensity-score based full matching on renal replacement therapy use.Three-year patient and graft survival for patients receiving renal replacement therapy were 77.7% and 72.6% compared with 85.1% and 79.4% for those not requiring renal replacement therapy (P<0.001 and P = 0.009 respectively, n = 725. In a Cox proportional hazards model, renal replacement therapy was a predictor of both patient death (hazard ratio (HR 1.59, 95% CI 1.01-2.50, P = 0.044 but not graft loss (HR 1.39, 95% CI 0.92-2.10, P = 0.114. In groups fully matched on baseline covariates, those not receiving renal replacement therapy with a serum creatinine greater than 175 μmol/L had a significantly worse risk of graft failure than those receiving renal replacement therapy.In patients being transplanted for acute liver failure, use of renal replacement therapy is a strong predictor of patient death and graft loss. Those not receiving renal replacement therapy with an elevated serum creatinine may be at greater risk of early graft failure than those receiving renal replacement therapy. A low threshold for instituting renal replacement therapy may therefore be beneficial.

    Minimally invasive spine surgery is increasingly used to treat various spinal pathologies with the goal of minimizing destruction of the surrounding tissues. Rhabdomyolysis (RM) is a rare but known complication of spine surgery, and acute renal failure (ARF) is in turn a potential complication of severe RM. The authors report the first known case series of RM and ARF following minimally invasive lateral spine surgery. The authors retrospectively reviewed data in all consecutive patients who underwent a minimally invasive lateral transpsoas approach for interbody fusion with the subsequent development of RM and ARF at 2 institutions between 2006 and 2009. Demographic variables, patient home medications, preoperative laboratory values, and anesthetic used during the procedure were reviewed. All patient data were recorded including the operative procedure, patient positioning, postoperative hospital course, operative time, blood loss, creatine phosphokinase (CPK), creatinine, duration of hospital stay, and complications. Five of 315 consecutive patients were identified with RM and ARF after undergoing minimally invasive lateral transpsoas spine surgery. There were 4 men and 1 woman with a mean age of 66 years (range 60-71 years). The mean body mass index was 31 kg/m2 and ranged from 25 to 40 kg/m2. Nineteen interbody levels had been fused, with a range of 3-6 levels per patient. The mean operative time was 420 minutes and ranged from 315 to 600 minutes. The CPK ranged from 5000 to 56,000 U/L, with a mean of 25,861 U/L. Two of the 5 patients required temporary hemodialysis, while 3 required only aggressive fluid resuscitation. The mean duration of the hospital stay was 12 days, with a range of 3-25 days. Rhabdomyolysis is a rare but known potential complication of spine surgery. The authors describe the first case series associated with the minimally invasive lateral approach. Surgeons must be aware of the possibility of postoperative RM and ARF, particularly in

    A 3-yr-old captive-born California sea lion (Zalophus californianus) developed Sarcocystis neurona-induced myositis and rhabdomyolysis that led to acute renal failure. The sea lion was successfully managed with fluid therapy, antiprotozoals, antibiotics, anti-inflammatories, antiemetics, gastroprotectants, and diuretics, but developed severe delayed hypercalcemia, a syndrome identified in humans after traumatic or exertion-induced rhabdomyolysis. Treatment with calcitonin was added to the management, and the individual recovered fully. The case emphasizes that animals with rhabdomyolysis-induced renal failure risk developing delayed hypercalcemia, which may be life threatening, and calcium levels should be closely monitored past the resolution of renal failure.

    Patients with renal insufficiency can have elevations of serum troponin without suspected clinical coronary ischemia. Although cardiovascular disease is the main cause of death in patients with renal failure, the process of elevation of serum troponin is not well known. Troponin T is more frequently elevated than troponin I in these patients which leads to uncertainty in the clinical interpretation of results. There are studies suggesting that troponin elevations are associated with a higher risk and increased mortality. To explain the process leading to troponin increases in this kind of pathology and to confirm its usefulness in the diagnosis, evolution and prognosis it would be necessary to carry out more clinical studies monitoring troponin and studying the stratification of risk.

    Rhabdomyolysis is an important cause of acute renal failure (ARF) and renal vasoconstriction is the main mechanism in the pathogenesis of ARF. Lipid peroxidation due to hydroxyl radical (.OH) formation and redox cycling of myoglobin also have a role. We investigated the disturbance in renal vascular reactivity to reveal the mechanisms leading to ARF. Female Wistar rats (n = 7) were injected with glycerol (10 mL/kg, 50% in saline) intramuscularly to induce rhabdomyolysis, and then the kidneys were isolated and perfused. We investigated acetylcholine (ACh)-induced endothelium-dependent and papaverine (PAP)-induced endothelium-independent vasodilation responses and renal nerve stimulation (RNS)-induced vasoconstrictions. These were also investigated both in rats which received either .OH scavenger, dimethylthiourea (DMTU: 500 mg/kg before glycerol injection and 125 mg/kg 8 h after glycerol injection, n = 7), or myoglobin redox cycling inhibitor, acetaminophen (ApAP: 100 mg/kg 2 h before glycerol injection and 100 mg/kg each 4 h, and 22 h after glycerol injection, n = 7). ACh-induced responses in glycerol group were decreased (p group. DMTU restored both endothelium-dependent vasodilation and RNS-induced vasoconstriction. ApAP had no effect on vascular responses. Both DMTU and ApAP exerted a partial protective effect in renal histology without restoring serum creatinine and blood urea nitrogen (BUN) levels or creatinine clearance. This study showed that endothelial dysfunction and increased vasoconstriction developed during rhabdomyolysis. .OH plays an important role in the development of these vascular responses. These findings suggest that decreased endothelium-dependent vasodilation and augmented renal sympathetic tonus contribute to the development of renal vasoconstriction during rhabdomyolysis-induced ARF.

    The effect of acute renal failure (ARF) induced by ischemia/reperfusion (I/R) of rat kidney on the expression of organic anion transporters (OATs) was examined. The level of serum indoxyl sulfate (IS), a uremic toxin and substrate of OATs in renal tubules, shows a marked increase with the progression of ARF. However, this increase was significantly attenuated by ingestion of cobalt. The level of mRNA and protein of both rOAT1 and rOAT3 were markedly depressed in the ischemic kidney. The uptake of p-aminohippuric acid (PAH) and estrone sulfate (ES) by renal slices of ischemic rats was significantly reduced compared to control rats. Renal slices taken from ischemic rats treated with cobalt displayed significantly elevated levels of ES uptake. Cobalt intake did not affect PAH uptake, indicating the functional restoration of rOAT3 but not rOAT1. The expression of Na(+)/K(+)-ATPase was markedly depressed in the ischemic kidney, suggesting that the inward Na(+) gradient in renal tubular cells had collapsed, thereby reducing the outward gradient of alpha-ketoglutarate, a driving force of both rOATs. The decreased expression of Na(+)/K(+)-ATPase was significantly restored by cobalt treatment. Our results suggest that the downregulation of renal rOAT1 and rOAT3 could be responsible for the increase in serum IS level of ischemic rats. Cobalt treatment has a significant protective effect on ischemia-induced ARF, being accompanied by the restoration of rOAT3 and/or Na(+)/K(+)-ATPase function. PMID:17245393

    The purpose of this study is to investigate whether the effect of cyclo-trans-4-L-hydroxyprolyl-L-serine (JBP485) on acute renal failure (ARF) induced by cisplatin is related to change in expression of renal Oat1, Oat3 and Mrp2 in rats. JBP485 reduced creatinine, blood urea nitrogen (BUN) and indoxyl sulfate (IS) in plasma and malondialdehyde (MDA) in kidney, and recovered the glomerular filtration rate (GFR) and the activity of superoxide dismutase (SOD) in cisplatin-treated rats. The plasma concentration of PAH (para-aminohippurate) determined by LC–MS/MS was increased markedly after intravenous administration of cisplatin, whereas cumulative urinary excretion of PAH and the uptake of PAH in kidney slices were significantly decreased. qRT-PCR and Western-blot showed a decrease in mRNA and protein of Oat1 and Oat3, an increase in mRNA and protein of Mrp2 in cisplatin-treated rats, and an increase in IS (a uremic toxin) after co-treatment with JBP485. It indicated that JBP485 promoted urinary excretion of toxins by upregulating renal Mrp2. This therefore gives in part the explanation about the mechanism by which JBP485 improves ARF induced by cisplatin in rats. -- Highlights: ► Cisplatin induces acute renal failure (ARF). ► The expression of Oat1, Oat3 and Mrp2 were changed during ARF. ► The regulated expression of Oat1, Oat3 and Mrp2 is an adaptive protected response. ► JBP485 could facilitate the adaptive protective action.

  4. A Rare Cause of Acute Renal Failure: Fenofibrate-Induced Rhabdomyolysis

    Full Text Available Fibrates are derivative of fibric acid and broad spectrum drugs which are commonly used in the treatment of dyslipidemia and hypertriglyceridemia. Side effects are often related with striated muscles, kidney and liver. Rhabdomyolysis developing with striated muscle destruction is potentially the most lethal of these side effects. Although several case reports of rhabdomyolysis have been reported due to the combination of statin and fenofibrate, fenofibrate alone rarely causes rhabdomyolysis. The purposes of this paper are to present a patient whom we diagnosed with acute renal injury due to use of fenofibrate in order to emphasize the importance of questioning drugs which have been used, and to review management of rhabdomyolysis due to fenofibrate use.

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

    A five years old boy was bitten by a Merrem's hump-nosed viper (Hypnale hypnale) in Central Province, Sri Lanka. He developed local swelling, incoagulable blood, thrombocytopenia, bleeding into the gastrointestinal tract, and acute renal failure. Treatment with Serum Institute of Indian polyspecific antivenom (specific for venoms of cobra, common krait, Russell's viper and saw-scaled viper) had no effect on the coagulopathy, which persisted for more than a week. The boy recovered after 27 d in hospital, during which he was treated with peritoneal dialysis for renal failure. Laboratory studies demonstrated that the venom of H. hypnale was procoagulant, fibrinolytic and aggregated platelets. This first authenticated case of life-threatening acute renal failure and haemostatic disturbances caused by H. hypnale, a species responsible for 27% of snake bites in Sri Lanka, demonstrates the need for a new antivenom with specific activity against the venom of this species.

  11. Diagnosing vascular causes of renal failure.

    Science.gov (United States)

    Abuelo, J G

    1995-10-15

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

    Full Text Available Kikuchi-Fujimoto disease, also known as histiocytic necrotizing lymphadenitis of unknown etiopathogenesis, is a self-limited disease which frequently appears as feverish lymphadenomegaly, thus creating the need for differential diagnosis with lymphoma, systemic lupus erythematosus (SLE, infectious mononucleosis, cat-scratch disease, and toxoplasmosis with lymphonodal impairment. However, there are cases in which it may evolve with complications such as aseptic meningitis, cerebellar ataxia, and aseptic myocarditis. We are presenting a case of a 24-year-old man who had an initial picture of arthralgia, evening fever and adenomegaly. Kikuchi disease was diagnosed through lymph node biopsy with immunohistochemistry and evolves with severe systemic manifestations, such as pericarditis with cardiac tamponade, pneumonitis, hepatitis, and acute kidney failure - the latter has not been reported in literature yet. There was significant improvement of the clinical picture with prednisone

  13. Calpastatin overexpression prevents progression of S-1,2-dichlorovinyl-L-cysteine (DCVC)-initiated acute renal injury and renal failure (ARF) in diabetes

    International Nuclear Information System (INIS)

    Previously we have shown that 90% of streptozotocin (STZ)-induced type-1 diabetic (DB) mice survive from acute renal failure (ARF) and death induced by a normally LD9 dose (75 mg/kg, i.p.) of the nephrotoxicant S-1,2-dichlorovinyl-L-cysteine (DCVC). This remarkable protection is due to a combination of slower progression of DCVC-initiated renal injury and increased compensatory nephrogenic tissue repair in the DB kidneys. BRDU immunohistochemistry revealed that the DB condition led to 4-fold higher number of proximal tubular cells (PTC) entering S-phase of cell cycle. In the present study, we tested the hypothesis that DB-induced augmentation of PTC into S-phase is accompanied by overexpression of the calpain-inhibitor calpastatin, which endogenously prevents the progression of DCVC-initiated renal injury mediated by the calpain escaping out of damaged PTCs. Immunohistochemical detection of renal calpain and its activity in the urine, over a time course after treatment with the LD9 dose of DCVC, indicated progressive increase in leakage of calpain into the extracellular spaces of the injured PTCs of the non-diabetic (NDB) kidneys as compared to the DB kidneys. Calpastatin expression was minimally detected in the NDB kidneys, using immunohistochemistry, over the time course. On the other hand, consistently higher number of tubules in the DB kidney showed calpastatin expression over the time course. The lower leakage of calpain in the DB kidneys was commensurate with constitutively higher expression of calpastatin in the S-phase-laden PTCs of these mice. To test the protective role of newly divided/dividing PTCs, DB mice were given the anti-mitotic agent colchicine (CLC) (2 mg/kg and 1.5 mg/kg, i.p., on days 8 and 10 after STZ injection) prior to challenge with a LD9 dose of DCVC, which led to 100% mortality by 48 h. Mortality was due to rapid progression of DCVC-initiated renal injury, suggesting that newly divided/dividing cells are instrumental in mitigating the

  17. Acute renal dysfunction in liver diseases

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Renal dysfunction is common in liver diseases, either as part of multiorgan involvement in acute illness or secondary to advanced liver disease. The presence of renal impairment in both groups is a poor prognostic indicator. Renal failure is often multifactorial and can present as pre-renal or intrinsic renal dysfunction. Obstructive or post renal dysfunction only rarely complicates liver disease. Hepatorenal syndrome (MRS) is a unique form of renal failure associated with advanced liver disease or cirrhosis, and is characterized by functional renal impairment without significant changes in renal histology. Irrespective of the type of renal failure, renal hypoperfusion is the central pathogenetic mechanism, due either to reduced perfusion pressure or increased renal vascular resistance. Volume expansion, avoidance of precipitating factors and treatment of underlying liver disease constitute the mainstay of therapy to prevent and reverse renal impairment. Splanchnic vasoconstrictor agents, such as terlipressin, along with volume expansion, and early placement of transjugular intrahepatic portosystemic shunt (TIPS) may be effective in improving renal function in HRS. Continuous renal replacement therapy (CRRT) and molecular absorbent recirculating system (MARS) in selected patients may be life saving while awaiting liver transplantation.

    2013-06-01

    Renal failure secondary to acetaminophen poisoning is rare and occurs in approximately 1-2 % of patients with acetaminophen overdose. The pathophysiology is still being debated, and renal acetaminophen toxicity consists of acute tubular necrosis, without complication if treated promptly. Renal involvement can sometimes occur without prior liver disease, and early renal manifestations usually occur between the 2nd and 7th day after the acute acetaminophen poisoning. While therapy is exclusively symptomatic, sometimes serious metabolic complications can be observed. The monitoring of renal function should therefore be considered as an integral part of the management of children with acute, severe acetaminophen intoxication. We report 3 cases of adolescents who presented with acute renal failure as a result of voluntary drug intoxication with acetaminophen. One of these 3 girls developed severe renal injury without elevated hepatic transaminases. None of the 3 girls' renal function required hemodialysis, but one of the 3 patients had metabolic complications after her acetaminophen poisoning. PMID:23628119

    A schizophrenic woman, aged 45, was admitted complaining of high fever, oliguria, blackish urine, muscle swelling and pain. She had been treated for the past 3 years with haloperidol (8 mg), levomepromazine (150 mg), chlorpromazine (75 mg), lithium carbonate (600 mg), bromocriptine mesilate (7.5 mg), etizolam (1 mg), and flunitrazepam (2 mg), Physical examination revealed her to be an obese and uncommunicatable woman with swelling and weakness of the extremities and abdominal distension without borborygmus. Urine was dark brown and (+) for protein and occult blood. Blood chemistry analysis revealed BUN 71 mg/dl, creatinine 6.8 mg/dl, CPK 143,850 IU and myoglobin 3,980 ng/ml. PRA on the 11th hospital day was 96 ng/ml/hour. This patient fulfilled the Levenson's diagnostic criteria for manifestations of neuroleptic malignant syndrome (NMS). High PRA did not decrease after cessation of the diuretics. After treatment with dantrolene sodium and 10 treatments with hemodialysis, azotemia disappeared with the start of diuresis. The PRA also decreased to the normal level. Characteristic acceleration of the central sympathetic stimuli in NMS seemed to have induced hyperreninemia, which together with rhabdomyolysis, might have contributed to the development of acute renal failure.

    Decompensation in heart failure occurs when the heart fails to balance venous return with cardiac output, leading to fluid congestion and contributing to mortality. Decompensated heart failure can cause acute kidney injury (AKI), which further increases mortality. Heart failure activates signaling systems that are deleterious to kidneys such as renal sympathetic nerve activity (RSNA), renin-angiotensin-aldosterone system, and vasopressin secretion. All three reduce renal blood flow (RBF) and increase tubular sodium reabsorption, which may increase renal oxygen consumption causing AKI through renal tissue hypoxia. Vasopressin contributes to venous congestion through aquaporin-mediated water retention. Additional water retention may be mediated through vasopressin-induced medullary urea transport and hyaluronan but needs further study. In addition, there are several systems that could protect the kidneys and reduce fluid retention such as natriuretic peptides, prostaglandins, and nitric oxide. However, the effect of natriuretic peptides and nitric oxide are blunted in decompensation, partly due to oxidative stress. This review considers how neurohormonal signaling in heart failure drives fluid retention by the kidneys and thus exacerbates decompensation. It further identifies areas where there is limited data, such as signaling systems 20-HETE, purines, endothelin, the role of renal water retention mechanisms for congestion, and renal hypoxia in AKI during heart failure.

    Full Text Available Background/Aims: Lipopolysaccharides (LPS binding to Toll-like receptor 4 (TLR4 activate NADPH oxidase gp91 subunit-mediated inflammation and oxidative damage. Recognizing the high binding affinity of sialic acid (SA with LPS, we further explored the preventive potential of SA pretreatment on LPS-evoked acute renal failure (ARF. Methods: We determined the effect of intravenous SA 30 min before LPS-induced injury in urethane-anesthetized female Wistar rats by evaluating kidney reactive oxygen species (ROS responses, renal and systemic hemodynamics, renal function, histopathology, and molecular mechanisms. Results: LPS time-dependently reduced arterial blood pressure, renal microcirculation, and increased blood urea nitrogen and creatinine in the rats. LPS enhanced monocyte/macrophage infiltration and ROS production, and subsequently impaired kidneys with the enhancement of TLR4/NADPH oxidase gp91/Caspase 3/poly-(ADP-ribose-polymerase (PARP-mediated apoptosis in the kidneys. SA pretreatment effectively alleviated LPS-induced ARF. The levels of LPS-increased ED-1 infiltration and ROS production in the kidney were significantly depressed by SA pretreatment. Furthermore, SA pretreatment significantly depressed TLR4 activation, gp91 expression, and Caspase 3/PARP induced apoptosis in the kidneys. Conclusion: We suggest that pretreatment of SA significantly and preventively attenuated LPS-induced detrimental effects on systemic and renal hemodynamics, renal ROS production and renal function, as well as, LPS-activated TLR4/gp91/Caspase3 mediated apoptosis signaling.

    Recent data suggest that exercise training (ExT) is beneficial in chronic heart failure (CHF) because it improves autonomic and peripheral vascular function. In this study, we hypothesized that ExT in the CHF state ameliorates the renal vasoconstrictor responses to hypoxia and that this beneficial effect is mediated by changes in α1-adrenergic receptor activation. CHF was induced in rabbits. Renal blood flow (RBF) and renal vascular conductance (RVC) responses to 6 min of 5% isocapnic hypoxia were assessed in the conscious state in sedentary (SED) and ExT rabbits with CHF with and without α1-adrenergic blockade. α1-adrenergic receptor expression in the kidney cortex was also evaluated. A significant decline in baseline RBF and RVC and an exaggerated renal vasoconstriction during acute hypoxia occurred in CHF-SED rabbits compared with the prepaced state (P hypoxia to those of the prepaced state. α1-adrenergic blockade partially prevented the decline in RBF and RVC in CHF-SED rabbits and eliminated the differences in hypoxia responses between SED and ExT animals. Unilateral renal denervation (DnX) blocked the hypoxia-induced renal vasoconstriction in CHF-SED rabbits. α1-adrenergic protein in the renal cortex of animals with CHF was increased in SED animals and normalized after ExT. These data provide evidence that the acute decline in RBF during hypoxia is caused entirely by the renal nerves but is only partially mediated by α1-adrenergic receptors. Nonetheless, α1-adrenergic receptors play an important role in the beneficial effects of ExT in the kidney. PMID:26607245

    AIM: To evaluate the possibility of an association between polyethylene glycol (PEG) and acute renal failure (ARF) in elderly patients using a health insurance claims database.METHODS: We conducted a population-based casecrossover study using information obtained from Korean Health Insurance Review and Assessment Service (HIRA)claims from January 1, 2005 to December 31, 2005(Seoul, Korea). The study population consisted of elderly patients who received PEG prior to experiencing their first ARF-related hospitalization from April 1, 2005 to December 31, 2005. For each patient, one case and two control periods were matched. PEG use in a 2- or 4-wk window period prior to hospitalization for ARF was compared with PEG use in two earlier 2- or 4-wk control window periods. Conditional logistic regression analysis was used to estimate odds ratios (ORs) and 95% CI, adjusting for concomitant uses of diuretics, angiotensin converting enzyme inhibitors, non-steroidal anti-inflammatory drugs,antibiotics, anti-cancer drugs, and contrast media.RESULTS: Within the HIRA database which contained 1 093 262 elderly patients, 1156 hospitalized ARF cases were identified. Among these cases, PEG was prescribed to 17 (1.5%) patients before hospitalization. The adjusted ORs when applying the 2- and 4-wk window periods were 0.4 (95% CI: 0.03-5.24) and 2.1 (95% CI:0.16-27.78), respectively.CONCLUSION: No increased risk of ARF was found in elderly PEG users. However, based on the limited number of study subjects, further analysis should be performed to confirm these results.

    Acute renal cortical necrosis in which there is destruction of the renal cortex and sparing of the renal medulla, is a relatively rare cause of acute renal failure. A definitive diagnosis of acute renal cortical necrosis is based on renal biopsy, but on CT(computed tomography) the rather specific contrast-enhanced appearance of acute renal cortical necrosis has been described. As renal biopsy is not available, contrast-enhanced CT is a useful, noninvasive investigate modality for the early diagnosis of acute renal cortical necrosis. We report the characteristic CT findings of acute renal cortical necrosis in a patient with acute renal failure following an operation for abdominal trauma.

    Full Text Available La acidosis láctica es una complicación grave pero infrecuente asociada al empleo de metformina. Se discuten los mecanismos fisiopatológicos implicados en la acidosis láctica, con especial atención al papel potencial del fármaco. Presentamos un caso severo de este efecto secundario de la metformina en una paciente con diabetes tipo 2 que ingresó en el Servicio de Urgencias Hospitalario por un cuadro de insuficiencia renal aguda. El diagnóstico quedó apoyado por unos niveles séricos elevados de la biguanida, procedimiento escasamente utilizado en la práctica clínica. El tratamiento consiste en suspender la administración del fármaco e iniciar de forma inmediata la hemodiálisis con bicarbonato, lo cual proporciona un tratamiento sintomático y etiológico al eliminar del suero tanto el lactato como el antidiabético oral. Los síntomas de la acidosis láctica por metformina son inespecíficos y el comienzo es sutil, lo que hace necesario un alto nivel de sospecha para establecer un diagnostico precoz.Lactic acidosis is a serious but uncommon side effect of metformin use. We discuss the pathophysiological mechanisms of lactic acidosis with particular regard to the role played by the drug as a potential cause of the entity. We report on a severe case of this kind of drug toxicity in a patient with type 2 diabetes mellitus, admitted to the emergency department with acute renal failure symptoms. The diagnosis was supported by elevated serum levels of the biguanide, a procedure scarcely used in clinical practice. The management of this complication consists in drug discontinuation and hemodialysis with bicarbonate that provides symptomatic and ethiological treatment by removing both the lactate and the hypoglycemic agent from the serum. Since the symptoms of metformin-associated lactic acidosis are unspecific and its onset is subtle, a high level of suspicion is needed to establish an early diagnosis.

    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.

    Full Text Available Abstract Background Because of the rapid growth in elderly population, polypharmacy has become a serious public health issue worldwide. Although acute renal failure (ARF is one negative consequence of polypharmacy, the association between the duration of polypharmacy and ARF remains unclear. We therefore assessed this association using a population-based database. Methods Data were collected from the Taiwan National Health Insurance Research Database (NHIRD from 2003 through 2006. The case group included patients hospitalized for ARF during 2006, but not admitted due to trauma, surgery, burn trauma, car accident, transplantation, or infectious diseases; the control group included patients hospitalized without ARF. The cumulative number of days of polypharmacy (defined as more than 5 prescriptions per day for 1 year prior to admission was determined, with patients further subdivided into 4 categories: less than 30 days, 31–90 days, 91–180 days, and over 181 days. The dependent variable was ARF, and the control variables were age, gender, comorbidities in patients hospitalized for ARF, stay in ICUs during ARF hospitalization and site of operation for prior admissions within one month of ARF hospitalization. Results Of 20,790 patients who were admitted to hospitals for ARF in 2006, 12,314 (59.23 % were male and more than 60 % were older than 65 years. Of patients with and without ARF, 16.14 % and 10.61 %, respectively, received polypharmacy for 91–180 days and 50.22 % and 24.12 %, respectively, for over 181 days. A statistical model indicated that, relative to patients who received polypharmacy for less than 30 days, those who received polypharmacy for 31–90, 91–180 and over 181 days had odds ratios of developing ARF of 1.33 (p Conclusions We observed statistically significant associations between the duration of polypharmacy and the occurrence of ARF.

    The introduction of novel agents in multiple myeloma therapy has dramatically improved survival in latest years. Great progress has also been detected in particular poor clinical situation such as acute renal failure in which survival was dismal in the past. Treatment with bortezomib, thalidomide and dialysis associated with high cut-off (HCO) filters can recover more than two thirds of myeloma patients with an end stage renal failure. Novel proteasome inhibitors and immunomodulating agents (IMID's) are even more promising in this set of patients. Aim of this review is to provide an overview of treatments of multiple myeloma patients with acute renal failure coming from most recent clinical trials. PMID:25329484

  17. Sustained oxidative stress causes late acute renal failure via duplex regulation on p38 MAPK and Akt phosphorylation in severely burned rats.

    Directory of Open Access Journals (Sweden)

    Yafei Feng

    Full Text Available BACKGROUND: Clinical evidence indicates that late acute renal failure (ARF predicts high mortality in severely burned patients but the pathophysiology of late ARF remains undefined. This study was designed to test the hypothesis that sustained reactive oxygen species (ROS induced late ARF in a severely burned rat model and to investigate the signaling mechanisms involved. MATERIALS AND METHODS: Rats were exposed to 100°C bath for 15 s to induce severe burn injury (40% of total body surface area. Renal function, ROS generation, tubular necrosis and apoptosis, and phosphorylation of MAPK and Akt were measured during 72 hours after burn. RESULTS: Renal function as assessed by serum creatinine and blood urea nitrogen deteriorated significantly at 3 h after burn, alleviated at 6 h but worsened at 48 h and 72 h, indicating a late ARF was induced. Apoptotic cells and cleavage caspase-3 in the kidney went up slowly and turned into significant at 48 h and 72 h. Tubular cell ROS production shot up at 6 h and continuously rose during the 72-h experiment. Scavenging ROS with tempol markedly attenuated tubular apoptosis and renal dysfunction at 72 h after burn. Interestingly, renal p38 MAPK phosphorylation elevated in a time dependent manner whereas Akt phosphorylation increased during the first 24 h but decreased at 48 h after burn. The p38 MAPK specific inhibitor SB203580 alleviated whereas Akt inhibitor exacerbated burn-induced tubular apoptosis and renal dysfunction. Furthermore, tempol treatment exerted a duplex regulation through inhibiting p38 MAPK phosphorylation but further increasing Akt phosphorylation at 72 h postburn. CONCLUSIONS: These results demonstrate that sustained renal ROS overproduction induces continuous tubular cell apoptosis and thus a late ARF at 72 h after burn in severely burned rats, which may result from ROS-mediated activation of p38 MAPK but a late inhibition of Akt phosphorylation.

    Acute renal failure, now termed acute kidney injury(AKI), is frequently found in patients with cirrhosis. The occurrence of AKI, irrespective of the underlying cause, is associated with reduced in-hospital, 3-mo and 1-year survival. Hepatorenal syndrome is associated with the worst outcome among AKI patients with cirrhosis. Several definitions for AKI that have been proposed are outlined and evaluated in this paper. Among these, the International Club for Ascites-AKI criteria substantially strengthen the quality of early diagnosis and intervention according to underlying cause of AKI.

    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.

    We investigated the effects of JBP485 (an anti-inflammatory dipeptide and a substrate of OAT) on regulation of the expression and function of renal Oat1 and Oat3, which can accelerate the excretion of accumulated uremic toxins (e.g. indoxyl sulfate) in the kidney to improve gentamicin-induced ARF in rats. JBP485 caused a significant decrease in the accumulation of endogenous substances (creatinine, blood urea nitrogen and indoxyl sulfate) in vivo, an increase in the excretion of exogenous compounds (lisinopril and inulin) into urine, and up-regulation of the expressions of renal Oat1 and Oat3 in the kidney tissues and slices via substrate induction. To determine the effect of JBP485 on the accelerated excretion of uremic toxins mediated by Oat1 and Oat3, the mRNA and protein expression levels of renal basolateral Oats were assessed by quantitative real-time PCR, western blot, immunohistochemical analysis and an immunofluorescence method. Gentamicin down-regulated the expression of Oats mRNA and protein in rat kidney, and these effects were reversed after administration of JBP485. In addition, JBP485 caused a significant decrease in MPO and MDA levels in the kidney, and improved the pathological condition of rat kidney. These results indicated that JBP485 improved acute renal failure by increasing the expression and function of Oat1 and Oat3, and by decreasing overoxidation of the kidney in gentamicin-induced ARF rats.

    The Ministry of Health of Panama (MINSA) received several reports of ill persons who had clinical presentations of acute renal insufficiency or failure during September and October 2006. On 01 October 2006, the MINSA formally asked the Pan-American Health Organization (PAHO) and the US Centers for Disease Control and Prevention (CDC) to assist with the investigation. Additional agencies involved in the response included the US Food and Drug Administration (FDA), the Gorgas Institute for Health Studies (GIHS), and the Social Security Health System (SSHS) of Panama. Through a joint effort, the MINSA, CDC, FDA, GIHS, SSHS, and PAHO were able to characterize the illness, identify the etiological agent, identify the population-at-risk, and launch an unprecedented media and social mobilization effort to prevent additional cases.International outbreak responses may require familiarity with basic emergency management principles beyond technical or scientific considerations. The management, logistical capabilities, team interaction, and efficiency of outbreak investigations can be enhanced substantially by having staff already familiar with common operational frameworks for incident responses. This report describes the inter-agency coordination and organizational structure implemented during an international response to identify the cause of an outbreak of acute renal failure in Panama.

    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.

    Full Text Available Leptospirosis is an important cause of acute renal failure in our environment. Although several mechanisms are implicated, the role of rhabdomyolysis in the pathogenesis of acute renal failure in leptospirosis has not been analysed. Sixteen patients with the diagnosis of leptospiroses consecutively admitted to the hospital were prospectively studied. The disease was characterized by sudden onset in all patients and, at admission, jaundice, conjunctival suffusion and myalgias. Mild to moderate proteinuria with unremarkable urinary sediment was recorded in 37.5% of the patients and abnormal levels of urea creatinine were found in 87.5% and 74.0%, respectively. Increased levels of aminotranspherase were documented in all 12 and CPK in all 10 patients studied. Serum myoglobin levels greater than 120µg/l recorded in 56.2%. A correlation between myoglobin and renal failure or severity of disease, however, could not be established.Leptospirose é uma importante causa de insuficiência renal aguda, em nosso ambiente.

    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.

We determined the characteristics of hospitalized AHF patients who experienced no worsening renal function (non-WRF, WRFt, or WRFp, and the relationship between cohorts and AHF-related outcomes. Methods and results: A patient’s first AHF hospitalization (index was identified in the Cerner Health Facts® database (January 2008-March 2011. Patients had WRF if serum creatinine (SCr was ≥0.3 mg/dL and increased ≥25% from baseline, and they were designated as WRFp if present at discharge or WRFt if not present at discharge. A total of 55,436 patients were selected (non-WRF =77%, WRFp =10%, WRFt =13%. WRFp had greater comorbidity burden than WRFt. At index hospitalization, WRFp patients had the highest mortality, whereas WRFt patients had the longest length of stay (LOS and highest costs. These trends were observed at 30, 180, and 365 days postdischarge and confirmed by multivariable analyses. WRF patients had more AHF-related readmissions than non-WRF patients. In sensitivity analyses of the patient subset with live index hospitalization discharges, postdischarge LOS and costs were highest in WRFt patients, whereas mortality associated with a HF hospitalization was significantly higher for WRF patients vs non-WRF patients, with no difference between WRFp and WRFt. Conclusion: In patients hospitalized for AHF, WRFp was associated with the highest mortality, whereas WRFt was associated with the highest LOS and costs. WRF patients had higher readmissions than non

    The aim of this study was to explore clinical features of renal infarction (RI) that may have a role in diagnosis and treatment in our patient cohort and provide data on midterm renal functions. Medical records of patients with diagnosis of acute RI, established by contrast enhanced computed tomography (CT) and at least 1 year follow-up data, who were hospitalized in our clinic between 1998 and 2012 were retrospectively reviewed; including descriptive data, clinical signs and symptoms, etiologic factors, laboratory findings, and prescribed treatments. Patients with solitary infarct were treated with acetylsalicylic acid (ASA) only, whereas patients with atrial fibrillation (AF) or multiple or global infarct were treated with anticoagulants. Estimated Glomerular Filtration Rate (eGFR) referring to renal functions was determined by the Modification of Diet in Renal Disease (MDRD) formula. Twenty-seven renal units of 23 patients with acute RI were identified. The mean age was 59.7 ± 15.7 years. Fourteen patients (60.8%) with RI had atrial fibrillation (AF) as an etiologic factor of which four had concomitant mesenteric ischemia at diagnosis. At presentation, 20 patients (86.9%) had elevated serum lactate dehydrogenase (LDH), 18 patients (78.2%) had leukocytosis, and 16 patients (69.5%) had microscopic hematuria. Two patients with concomitant mesenteric ischemia and AF passed away during follow up. Mean eGFR was 70.8 ± 23.2 mL/min/1.73 m(2) at admission and increased to 82.3 ± 23.4 mL/min/1.73 m(2) at 1 year follow up. RI should be considered in patients with persistent flank or abdominal pain, particularly if they are at high risk of thromboembolism. Antiplatelet and/or anticoagulant drugs are both effective treatment options according to the amplitude of the infarct for preserving kidney functions.

    Chronic renal failure (CRF) is the irreversible deterioration of renal function that gradually progresses to end stage renal disease (ESRD). The chief causes of CRF include obstructive uropathy, primary glomerular diseases, reflux nephropathy and hypoplastic or dysplastic kidneys. Progressive hyperperfusion and hyperfiltration causes increasing glomerular injury and further renal damage. Symptoms of CRF are usually seen when GFR is between 10-25% of normal. Children with severe CRF often suffer from failure to thrive, growth retardation, acidosis, anemia and renal osteodystrophy. Management of CRF aims at retarding progression of renal damage and treatment of complications related to renal dysfunction. Measures suggested to retard progression include protein restriction, strict control of hypertension, use of angiotensin converting enzyme inhibitors and control of hyperlipidemia. Appropriate amounts of protein and calories are recommended to prevent growth failure. Nutritional supplements are often required. The availability of recombinant erythropoietin, calcitriol and human growth hormone has significantly improved the management of these patients. Once ESRD supervenes, renal replacement therapy in the form of chronic peritoneal or hemodialysis and transplantation is necessary.

    Managing patients with heart failure (HF) is a challenging task within itself, but the presence of associated worsening renal function can greatly increase mortality and morbidity. Early diagnosis and treatment is the key to prevent re-hospitalizations and reduce healthcare costs. Biomarkers have long been established as highly sensitive and specific tools in diagnosing and prognosticating patients with HF. Reflecting distinct pathophysiological events and ongoing cellular insult, biomarkers have been proven superior to conventional laboratory tests. Availability of better assays and rapid analysis has allowed the use of biomarkers as point-of-care tests in the emergency department and at the patient's bed-side. Acute HF patients often go on to develop worsening renal function, termed as acute cardiorenal syndrome. The growing breadth of studies has shown the implications of combining multiple biomarkers to better chart outcomes and produce desirable results in such patients.

    2004-08-01

    Full Text Available Abstract Background Dialysis disequilibrium syndrome (DDS is the clinical phenomenon of acute neurologic symptoms attributed to cerebral edema that occurs during or following intermittent hemodialysis (HD. We describe a case of DDS-induced cerebral edema that resulted in irreversible brain injury and death following acute HD and review the relevant literature of the association of DDS and HD. Case Presentation A 22-year-old male with obstructive uropathy presented to hospital with severe sepsis syndrome secondary to pneumonia. Laboratory investigations included a pH of 6.95, PaCO2 10 mmHg, HCO3 2 mmol/L, serum sodium 132 mmol/L, serum osmolality 330 mosmol/kg, and urea 130 mg/dL (46.7 mmol/L. Diagnostic imaging demonstrated multifocal pneumonia, bilateral hydronephrosis and bladder wall thickening. During HD the patient became progressively obtunded. Repeat laboratory investigations showed pH 7.36, HCO3 19 mmol/L, potassium 1.8 mmol/L, and urea 38.4 mg/dL (13.7 mmol/L (urea-reduction-ratio 71%. Following HD, spontaneous movements were absent with no pupillary or brainstem reflexes. Head CT-scan showed diffuse cerebral edema with effacement of basal cisterns and generalized loss of gray-white differentiation. Brain death was declared. Conclusions Death is a rare consequence of DDS in adults following HD. Several features may have predisposed this patient to DDS including: central nervous system adaptations from chronic kidney disease with efficient serum urea removal and correction of serum hyperosmolality; severe cerebral intracellular acidosis; relative hypercapnea; and post-HD hemodynamic instability with compounded cerebral ischemia.

    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.

    The main goal of early diagnosis of renal disease and renal failure in dogs and cats is to enable timely application of therapeutic interventions that may slow or halt disease progression. Strategies for early diagnosis of renal disease use urine tests that detect proteinuria that is a manifestation of altered glomerular permselectivity or impaired urine-concentrating ability as well blood tests to evaluate plasma creatinine concentration. Animals with progressive renal disease should be carefully investigated and treated appropriately. Animals with mild, possibly nonprogressive, renal disease should be monitored adequately to detect any worsening trends,which should lead to further investigation and treatment even if the increments of change are small.

    To assess the diagnostic value of indices measured on a first-pass curve, we performed 72 radionuclide renal first-pass studies (RFP) in 21 patients during the early weeks following renal allograft transplantation. The diagnosis was based on standard clinical and biochemical data and on fine needle aspiration biopsy (FNAB) of the transplant. Aortic and renal first-pass curves were filtered using a true low-pass filter and five different indices of renal perfusion were computed, using formulae from the literature. Statistical analysis performed on the aortic and renal indices indicated excellent reproducibility of the isotopic study. Although renal indices presented a rather large scatter, they all discriminated well between normal and rejection. Three indices have a particularly good diagnostic value. In the discrimination between rejection and Acute Tubular Necrosis (ATN), only one index gave satisfying results. The indices, however, indicate that there are probably ATN with an alternation of renal perfusion and rejection episodes where perfusion is almost intact. We conclude that radionuclide first-pass study allows accurate and reproducible quantitation of renal allograft perfusion. The measured parameters are helpful to follow up the course of a post-transplantation renal failure episode and to gain more insight into renal ischemia following transplantation.

    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 aim of our study was to evaluate the occurrence of middle and long-term chronic renal failure (CRF) after orthotopic liver transplantation (OLT) in relation to acute renal failure (ARF). We prospectively monitored 75 patients, studying renal function on the basis of serum creatinine and glomerular filtration rate as estimated using the Modification of Diet in Renal Disease formula before as well as 1,6, and 12 months after OLT. The prevalence of ARF was 56% classified by the Acute Kidney injury Network criteria (52% stage 1, 29% stage 2, and 19% stage 3). The occurrences of CRF were 18.6% (11/59), 11.5% (6/52), and 14% (6/43) at 1, 6, and 12 months after OLT, respectively. The occurrence of CRF before OLT was 14.7%. We did not find any association between ARF and post-OLT CRF. The most relevant result of our study was the association between CRF at 6 and 12 months after transplantation with pre-OLT CRF on univariate and multivariate analysis. We suggest that evaluation of pre-OLT renal function should always be considered in the follow-up of liver transplant patients. Pre-OLT renal dysfunction must be recognized to be a risk factor for post-OLT CRF, representing important criterion to define specific therapeutic interventions to reduce patient morbidity and mortality.

    Anticoagulation may be difficult to implement in patients suffering from chronic renal failure on account of platelet disorders and impaired clearance of some anticoagulant drugs. Although no adjustment of heparin and coumarin dosage is necessary, more frequent testing of coagulation pathways may be required when these drugs are used in patients with renal failure. Long-term use of LMWH should be implemented cautiously with regular testing of anti-factor Xa activity and a half-dose may be advocated in patients with a creatinine clearance heparin-induced thrombocytopenia with regular monitoring of coagulation tests.

MÉTODO: Foram estudados, de modo prospectivo, 150 pacientes submetidos à cirurgia cardíaca, durante 21 meses consecutivos, havendo um leve predomínio de homens (57%, idade média de 56 ± 15 anos, sendo que 66% apresentavam insuficiência coronariana como principal diagnóstico e 34% valvulopatias. A mediana da creatinina sérica no período pré-operatório foi de 1,1 mg/dl. IRA foi definida como elevação de 30% da creatinina sérica basal. O protocolo de variáveis clínicas teve seu preenchimento iniciado 48 horas antes do procedimento cirúrgico e encerrado 48 horas após o mesmo, incluindo variáveis cardiológicas e não-cardiológicas, além de resultados laboratoriais. RESULTADOS: A IRA esteve presente em 34% dos casos. Após análise multivariada, presença de doença vascular periférica foi fator pré-operatório identificado. CONCLUSÃO: Os resultados obtidos nesse estudo permitiram sinalizar alguns fatores contributivos para o desenvolvimento de IRA em cirurgia cardíaca, o que pode possibilitar condutas clínicas simples para evitar a disfunção renal nestas situações e, conseqüentemente, redução da taxa de mortalidade.

    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. In addition, this document also provides an update of the various immunosuppressive regimens tested in this population for the prevention and control of post-transplantation deterioration of renal function.

    Background Causes of “true” late kidney allograft failure remain unclear as study selection bias and limited follow-up risk incomplete representation of the spectrum. Methods We evaluated all unselected graft failures from 2008–2014 (n = 171; 0–36 years post-transplantation) by contemporary classification of indication biopsies “proximate” to failure, DSA assessment, clinical and biochemical data. Results The spectrum of graft failure changed markedly depending on the timing of allograft failure. Failures within the first year were most commonly attributed to technical failure, acute rejection (with T-cell mediated rejection [TCMR] dominating antibody-mediated rejection [ABMR]). Failures beyond a year were increasingly dominated by ABMR and ‘interstitial fibrosis with tubular atrophy’ without rejection, infection or recurrent disease (“IFTA”). Cases of IFTA associated with inflammation in non-scarred areas (compared with no inflammation or inflammation solely within scarred regions) were more commonly associated with episodes of prior rejection, late rejection and nonadherence, pointing to an alloimmune aetiology. Nonadherence and late rejection were common in ABMR and TCMR, particularly Acute Active ABMR. Acute Active ABMR and nonadherence were associated with younger age, faster functional decline, and less hyalinosis on biopsy. Chronic and Chronic Active ABMR were more commonly associated with Class II DSA. C1q-binding DSA, detected in 33% of ABMR episodes, were associated with shorter time to graft failure. Most non-biopsied patients were DSA-negative (16/21; 76.1%). Finally, twelve losses to recurrent disease were seen (16%). Conclusion This data from an unselected population identifies IFTA alongside ABMR as a very important cause of true late graft failure, with nonadherence-associated TCMR as a phenomenon in some patients. It highlights clinical and immunological characteristics of ABMR subgroups, and should inform clinical practice and

    A comparison was made between patients with a late diagnosis of chronic renal failure (1 month or less before starting dialysis, N = 96) and those with an early diagnosis (6 months or more, N = 45) in terms of the following aspects: referral characteristics during the pre-dialysis phase, demographic details and patient biochemistry prior to maintenance dialysis. Information was obtained by surveying consecutive patients with primary renal disease admitted to a university dialysis unit in São Paulo. Fifty-three percent of all patients surveyed had a late diagnosis. These patients had a lower median duration of symptoms (2 vs 6 months, P < 0.01) and were less likely to be referred for dialysis by a nephrologist (9% vs 51%, P < 0.001) than early diagnosis patients. In the early diagnosis group, 7 patients (16%) had follow-up care for less than 6 months and 11 (24%) did not receive any follow-up; 21 patients (47%) did not follow a low-protein diet. At the start of dialysis, patients with a late diagnosis had higher blood pressure and a higher rate of pulmonary infections (19% vs 4%, P = 0.03). Mean concentrations of BUN, serum creatinine and potassium were significantly higher and mean blood hematocrit was lower for the late diagnosis group. After 3 months of dialysis, the mortality rate was higher in the late than in the early diagnosis group (22.9% vs 6.7%, P = 0.02). Late diagnosis of chronic renal failure and lack of adequate follow-up care, prior to the start of dialysis, are common. Interventions to promote early diagnosis of chronic renal failure and to improve compliance with regular nephrological follow-up can be important to reduce the morbidity and the mortality of patients with chronic renal insufficiency.

    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.

    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.

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

  12. Acute respiratory failure following ovarian hyperstimulation syndrome

    2013-03-01

    Full Text Available Ovarian hyperstimulation syndrome is a serious and potentially life-threatening physiological complication that may be encountered in patients who undergo controlled ovarian hyperstimulation cycles. The syndrome is typically associated with regimes of exogenous gonadotropins, but it can be seen, albeit rarely, when clomiphene is administered during the induction phase. Although this syndrome is widely described in scientific literature and is well known by obstetricians, the knowledge of this pathological and potentially life-threatening condition is generally less than satisfactory among physicians. The dramatic increase in therapeutic strategies to treat infertility has pushed this condition into the realm of acute care therapy. The potential complications of this syndrome, including pulmonary involvement, should be considered and identified so as to allow a more appropriate diagnosis and management. We describe a case of a woman with an extremely severe (Stage 6 ovarian hyperstimulation syndrome who presented ascites, bilateral pleural effusion and severe respiratory failure treated with non-invasive ventilation. The patient was admitted to the intensive care unit because of severe respiratory failure, ascites, and bilateral pleural effusion due to ovarian hyperstimulation syndrome. Treatment included non-invasive ventilation and three thoracentesis procedures, plus the administration of albumin, colloid solutions and high-dose furosemid. Severe form of ovarian hyperstimulation syndrome is observed in 0.5-5% of the women treated, and intensive care may be required for management of thromboembolic complications, renal failure and severe respiratory failure. Pulmonary intensive care may involve thoracentesis, oxygen supplementation and, in more severe cases, assisted ventilation. To our knowledge, there have been only two studies in English language medical literature that describe severe respiratory failure treated with non

Patients had either serum creatinine (SCr) below 350 mumol/liter (N = 12) or terminal renal failure (N = 50). Specimens were examined by two independent observers using a carefully validated score system. Mean glomerular diameters were similar in ADPKD patients with early renal failure (176 +/- 38 microns) and in victims of traffic accidents (177 +/- 23 microns), while they were significantly greater in diabetics with comparable renal function (205 +/- 16 microns). Glomerular diameters in ADPKD patients with terminal renal failure (191 +/- 45 microns) and with early renal failure were not significantly different. On average, 29% of glomeruli (17 to 62) were globally sclerosed in early renal failure, and 49% (19 to 93) in terminal renal failure. The proportion of glomeruli with segmental sclerosis was less than 4% in both groups. Marked vascular sclerosis, interstitial fibrosis, and tubular atrophy were present in early renal failure, and even more so in terminal renal failure. Interstitial infiltrates were scarce and consisted mainly of CD4 positive lymphocytes and CD68 positive macrophages. Immunestaining with monoclonal renin antibodies showed an increased juxtaglomerular index and expression of renin by arterioles adjacent to cysts, as well as by cyst wall epithelia. The data show more severe vascular and interstitial, but not glomerular, changes in ADPKD with advanced as compared to early renal failure.

    Pregnancy in women with chronic renal failure is a complex therapeutic problem requiring a multidisciplinary approach. It is associated with a higher risk of many perinatal complications. The most common abnormalities are related to: progression of renal failure, development of preeclampsia development of nephrotic syndrome, anemic syndrome, IUGR and fetal death. The prognosis depends on the values of serum creatinine prior to pregnancy, the degree of deterioration of renal function, development of additional obstetric complications and the specific etiological reasons that have led to the occurrence of renal failure. Determining the optimum time for authorization birth depends on the condition of the mother, the condition of the fetus and the rate of progression of renal failure, and the deadline the pregnancy should be terminated is 35 weeks. We present a case of a patient with chronic renal failure, with favorable perinatal outcome. PMID:26137779

    2006-12-01

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

    Acute interstitial nephritis (AIN) secondary to trimethoprim-sulfamethoxazole (TMP-SMX) is well documented as a cause of acute renal failure in native kidneys. TMP-SMX is the standard prophylactic agent against pneumocystis carinii (PCP) used in the early post-transplant period, however, it has to date only been indirectly associated with AIN in renal allografts. DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS: We describe eleven renal transplant patients with acute allograft dysfunction in whom a transplant biopsy demonstrated primary histopathologic features of allergic AIN, all of whom were receiving TMP-SMX in addition to other medications known to cause AIN.

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

    Full Text Available Catatonia, originally described by Karl Kahlbaum in 1874, may be regarded as a set of clinical features found in a subtype of schizophrenia, but the syndrome may also stem from organic causes including vascular parkinsonism, brain masses, globus pallidus lesions, metabolic derangements, and pharmacologic agents, especially first generation antipsychotics. Catatonia may include paratonia, waxy flexibility (cerea flexibilitas, stupor, mutism, echolalia, and catalepsy (abnormal posturing. A case of catatonia as a result of acute renal failure in a patient with dementia with Lewy bodies is described. This patient recovered after intravenous fluid administration and reinstitution of the atypical dopamine receptor blocking agent quetiapine, but benzodiazepines and amantadine are additional possible treatments. Recognition of organic causes of catatonia leads to timely treatment and resolution of the syndrome.

    Amatoxins, which are mainly found in Amanita phalloides, Amanita virosa, and Galerina autumnalis, are responsible for the majority of fatal intoxication with green death cap. The intoxication is associated with acute liver failure, which explains the poor prognosis. Acute liver injury is generally preceeded by a gastrointestinal phase with nausea, vomiting and diarrhea. In the course, pre-renal kidney failure due to the associated fluid deficit and fulminant liver failure may occur. General guidelines for the treatment of amatoxin poisoning are yet not available. We report on three patients who suffered from amatoxin mushroom poisoning after ingestion of green death cap mushrooms. Based on the pathophysiology of amatoxin poisoning, we discuss a potential therapeutic approach. PMID:27359312

    AIM: To investigate the relationship between severe acute pancreatitis (SAP) and organ failure.METHODS: Clinical data of 74 cases of SAP from Jan. 1993 to Dec. 2002 were retrospectively reviewed, and the relationship between organ failure and age, gender, etiology,extent of necrosis, infection of necrosis and mortality was analyzed.RESULTS: A total of 47 patients (63.5 %) showed organ failure, 20 patients (27.0 %) multiple organ failure, whereas 27 patients (36.5 %) with dysfunction of a single organ system. Pulmonary failure was the most common organ dysfunction (23.0 %) among single organ failures. There were no significant differences in age, gender and gallstone pancreatitis among patients with or without organ failure (P>0.05). The incidence of organ failure in infected necrosis was not higher compared with sterile necrosis, and patients with increased amount of necrosis did not have an increased prevalence of organ failure (P>0.05). Patients with organ failure had a higher mortality rate compared with those without organ failure (P<0.05). The death of SAP was associated with multiple organ failure (P<0.005), pulmonary failure (P<0.005), cardiovascular dysfunction (P<0.05) and gastrointestinal dysfunction (P<0.05).CONCLUSION: Organ failure is common in patients with SAP, and patients with multiple organ failure and pulmonary failure have a higher mortality rate. Prevention and active treatment of organ failure can improve the outcome of patients with SAP.

  18. Novel biomarkers in acute heart failure: MR-pro-adrenomedullin.

    Science.gov (United States)

    Peacock, W Frank

    2014-10-01

    First isolated from human pheochromocytoma cells, adrenomedullin (ADM) is a peptide hormone with natriuretic, vasodilatory, and hypotensive effects mediated by cyclic adenosine monophosphate (cAMP), nitric oxide, and renal prostaglandin systems. ADM expression occurs in many tissues and organ systems, including cardiovascular, renal, pulmonary, cerebrovascular, gastrointestinal, and endocrine tissues where it acts as a circulating hormone and a local autocrine and paracrine hormone. ADM plasma concentrations are increased in hypertension, chronic renal disease, and heart failure. As ADM is unstable in vitro, it is necessary to measure its mid-regional pro-hormone fragment, the levels of which correspond to ADM concentration (MR-proADM). The prognostic potential of MR-proADM was recently demonstrated in the Biomarkers in Acute Heart Failure (BACH) trial. In this trial of 568 acute heart failure patients, MR-proADM was superior to both brain natriuretic peptide (BNP) and NT-proBNP in predicting mortality within 14 days. MR-proADM also provided significant additive incremental predictive value for 90-day mortality when added to BNP and NT-proBNP.

    Full Text Available Rhabdomyolysis is a syndrome characterized by muscle necrosis which causes the release of myoglobin into the bloodstream. The manifestations of this syndrome range from asymptomatic elevation of serum muscle enzymes to life-threatening cases associated with extremely high enzyme levels, electrolyte imbalance, and acute renal failure. Symptoms of rhabdomyolysis include dark urine, muscle weakness, and fatigue. Statins are commonly used drugs for the prevention and management of dyslipidemia. We present an interesting and critical case on statin-induced rhabdomyolysis with renal failure and previously undiagnosed idiopathic hypothyroidism.

    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.

    Despite the advances in critical care medicine, the hospital mortality in patients with acute kidney injury (AKI) requiring dialysis remains high. Depending on the underlying disease the in-house mortality is reported to be up to 80%. Several observational studies demonstrated an association between mortality and fluid overload. A primary mechanism of interest is that fluid overload causes tissue edema and subsequent reduction of perfusion, oxygenation and nutrient delivery. This results in further renal damage. In addition, fluid overload-related dilution within the extracellular space causes artificially low serum creatinine, which masks AKI diagnosis. As a consequence, renal protective management strategies are deferred, which further aggravates kidney injury. This aggravation of renal damage subsequently increases the mortality. This review discusses the role of fluid overload for outcomes in critically ill patients as described in the current literature and assesses criteria for the initiation of renal replacement therapy in this critically ill population.

    1993-09-01

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

    Full Text Available Nutritional support in acute renal failure must take into account the patient's catabolism and the treatment of the renal failure. Hypermetabolic failure is common in these patients, requiring continuous renal replacement therapy or daily hemodialysis. In patients with normal catabolism (urea nitrogen below 10 g/day and preserved diuresis, conservative treatment can be attempted. In these patients, relatively hypoproteic nutritional support is essential, using proteins with high biological value and limiting fluid and electrolyte intake according to the patient's individual requirements. Micronutrient intake should be adjusted, the only buffering agent used being bicarbonate. Limitations on fluid, electrolyte and nitrogen intake no longer apply when extrarenal clearance techniques are used but intake of these substances should be modified according to the type of clearance. Depending on their hemofiltration flow, continuous renal replacement systems require high daily nitrogen intake, which can sometimes reach 2.5 g protein/kg. The amount of volume replacement can induce energy overload and therefore the use of glucose-free replacement fluids and glucosefree dialysis or a glucose concentration of 1 g/L, with bicarbonate as a buffer, is recommended. Monitoring of electrolyte levels (especially those of phosphorus, potassium and magnesium and of micronutrients is essential and administration of these substances should be individually-tailored.El soporte nutricional en la insuficiencia renal aguda está condicionado por el catabolismo del paciente y por el tratamiento del fallo renal. En el paciente crítico es frecuente el fracaso hipermetabólico que obliga a técnicas continuas de reemplazo renal o a hemodiálisis diarias. En los enfermos con catabolismo normal (aparición de nitrógeno ureico inferior a 10 g/día y diuresis conservada se puede intentar un tratamiento conservador.

    Acute renal failure affects from 1% to 25% of patients admitted to intensive care units. These figures vary depending on the population studied and criteria. The complications of acute renal failure (fluid overload, metabolic acidosis, hyperkalemia, bleeding) are treated. However, mortality remains high despite the technological advances of recent years because acute renal failure is usually associated with sepsis, respiratory failure, serious injury, surgical complications or consumption coagulopathy. Mortality ranges from 30% to 90%. Although there is no universally accepted definition, the RIFLE classification gives us an operational tool to define the degree of acute renal failure and to standardize the initiation of renal replacement techniques as well as to evaluate the results. Therefore, nurses working within the intensive care unit must be familiar with this disease, with its treatment (drug or alternative) and with the prevention of possible complications. Equally, they must be capable of detecting the manifestations of dependency each one of the basic needs and to be able to identify the collaboration problems in order to achieve an individualized care plan.

    We investigated the incidence, risk factors and outcome of acute renal dysfunction (ARD) in patients with a fractured neck of femur. 170 consecutive patients were prospectively included in the Scottish Hip Fracture Audit database and retrospectively analysed. Historically, lack of consensus definition has hindered accurate reporting of ARD. ARD was defined using the 'RIFLE' criteria. 27 patients (16%) developed ARD. Risk factors were male sex, vascular disease, hypertension, diabetes, chronic kidney disease and pre-morbid use of nephrotoxic medications (pARD group 19%, 22% and 41% respectively, versus 0%, 4% and 13% in the non-ARD group (pARD group. Pre- and post-operative complications were 12 and 5 times more frequent respectively in the ARD group (p<0.01). Awareness of risk factors and serial measurements of renal function allow early identification and focused monitoring of these patients. PMID:19729159

    Full Text Available Within the first week of the disease, acute kidney injury (AKI is among the most common causes of mortality in acute pancreatitis (AP. Recently, serum angiopoietin-2 (Ang-2 has been associated with hyperdynamic state of the systemic circulation. The aim of this study was to examine the associations between Ang-2 and the clinical AP severity during the first 72 hours of the disease, and organ disfunction, including AKI. Methods. Study included patients admitted to the surgery ward, diagnosed with AP. AKI was diagnosed according to KDIGO guidelines and renal failure according to modified Marshall scoring system. Ang-2 was determined in serum with ELISA. Results. AP was classified as mild (MAP in 71% of patients, moderately severe (MSAP in 22%, and severe (SAP in 8%. During the first 72 hours of AP, 11 patients developed AKI and 6 developed renal failure. Ang-2 at 24, 48, and 72 hours following the onset of AP symptoms significantly predicted SAP and MSAP, as well as AKI and renal failure. Also, Ang-2 significantly correlated with acute phase proteins as well as with the indicators of renal disfunction. Conclusions. Serum Ang-2 may be a relevant predictor of AP severity, in particular of the development of AP-renal syndrome.

    Objective To copy the acute renal failure ( ARF) animal model and execute an experimental treatment of it in rabbits, to lay a foundation for the implementation of comprehensive experiment for undergraduate students. Method ARF model was set up through the injection of 50% glycerol (10 mL/kg). All the rabbits were monitored with ECG, Sodium bicarbonate solution, furosemide solution and CaCl2 solution were infused through the external jugular vein to the rabbits in the treatment group. Serum urea nitrogen ( BUN), serum creatinine (Cre)level,plasma pH,urine volume and urine creatinine changes of the rabbits were detected after 24 hours. Results The application of 50% glycerol intramuscular injection could replicate typical animal models with acute renal failure. Serum BUN and Cre levels concentration in the model group were obviously higher than those in the negative control group, the urine Cre concentration was also higher, while the urine volume per minute was less and a metabolic acidosis happened at the same time. In the treatment group, serum BUN and Cre levels were significantly lower than those in the model group, while urine volume per minute was more than that in the control group, and the metabolic acidosis was improved. The blood pressure of animals in the treatment group was a litter higher,but there was no difference compared with that in the negative control group, T wave was high and giant, and the QRS wave was widened in the model group compared with those in the negative control group. After the treatment,ECG of the animals in the model group gradually returned to normal state. Conclusion The method of intramuscular injection of 50% glycerol could be reliable to replicate the animal model with acute renal failure, and can be taken as a comprehensive experimental teaching method and widely used in the teaching of medical functional experiment.%目的 复制家免急性肾衰竭动物模型并进行实验性治疗,为本科学生综合性实

    1997-01-01

    Patients with chronic failure evidence various abnormalities in heme metabolism, primarily erythrocyte aminolevulinate dehydrase hypoactivity and increased plasma and erythrocyte porphyrin levels. Such abnormalities have also been observed in animals with both acute and chronic experimental renal failure. The aim of this work was to study these parameters of porphyrin metabolism in an experimental model of functional renal failure. A group of 11 male Wistar rats received 13 doses (25 mg/kg body weight/day) of cyclosporin A. Serum creatinine did not vary, but the blood urea nitrogen levels increased and a significant decrease in the creatinine clearance was observed. The drug also caused a marked decrease in the erythrocyte aminolevulinate dehydrase activity, a slight reduction of the hematocrit value, and increased levels of blood porphyrins. The plasma of treated rats showed capacity to inhibit aminolevulinate dehydrase activity when incubated in vitro with erythrocytes from control rats. Porphyrin metabolism remained unchanged in the liver. The daily diuresis was significantly decreased in the cyclosporin as compared to the control group; however, the porphyrinuria showed no changes. The derangements in the erythrocyte heme biosynthesis pathway observed in patients with chronic renal failure are reproducible in an experimental model of cyclosporin A-induced functional renal failure.

  14. Effects of renal failure on drug transport and metabolism.

    Renal failure not only alters the renal elimination, but also the non-renal disposition of drugs that are extensively metabolized by the liver. Although reduced metabolic enzyme activity in some cases can be responsible for the reduced drug clearance, alterations in the transporter systems may also be involved in the process. With the development of renal failure, the renal secretion of organic ions mediated by organic anion transporters (OATs) and organic cation transporters (OCTs) is decreased. 3-Carboxy-4-methyl-5-propyl-2-furanpropanoic acid (CMPF) and other organic anionic uremic toxins may directly inhibit the renal excretion of various drugs and endogenous organic acids by competitively inhibiting OATs. In addition, the expression of OAT1 and OCT2 was reduced in chronic renal failure (CRF) rats. Renal failure also impairs the liver uptake of drugs and organic anions, such as bromosulphophthalein (BSP), indocyanine green (ICG), and thyroxine, where organic anion transport polypeptides (OATPs) are the major transporters. Most previous studies have been done in animals or cell culture, very often in rat models, but these are presumed to reflect the presentation of advanced renal disease in humans as well. Recent studies demonstrate that the uremic toxins CMPF and indoxyl sulfate (IS) can directly inhibit rOatp2 and hOATP-C in hepatocytes. The protein content of the liver uptake transporters Oatp1, 2, and 4 were significantly decreased in CRF rats. Decreased activity of the intestinal efflux transporter, P-glycoprotein (P-gp), was also observed in CRF rats, with no significant change of protein content, suggesting that uremic toxins may suppress P-gp function. However, increased protein levels of multidrug resistance-associated protein (MRP) 2 in the kidney and MRP3 in the liver were found in CRF rats, suggesting an adaptive response that may serve as a protective mechanism.

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

  19. [Renal dysfunction in heart failure and hypervolumenia : Importance of congestion and backward failure].

    Science.gov (United States)

    Druml, W

    2014-05-01

    Traditionally, renal dysfunction in congestive heart failure (cardiorenal syndrome type 1) has been attributed to reduced cardiac output and low mean arterial perfusion pressure, which elicit a series of neurohumoral activations resulting in increased renal vascular resistance and decreased renal function.During the last decade, several studies have shown that the extent of renal dysfunction is not so closely associated with indices of forward failure-such as the cardiac index or mean arterial pressure-but rather with indicators of congestion, such as left ventricular enddiasystolic pressure or central venous pressure (CVP), which are indicators of backward failure. The impact of backward failure on renal function is not confined to an elevation of CVP, the renal drainage pressure, but includes a broad spectrum of mechanisms. Involved are the organ systems right heart, lung, the liver, the proinflammatory signals originating from the intestines, but also renal interstitial edema (renal compartment syndrome) and the intraabdominal pressure.The therapeutic measures must focus on the modulation of the preload adapted to the specific situation of an individual patient. This includes diuretics aiming at different segments of the tubulus system including antagonists of aldosteron and ADH, extracorporeal fluid elimination by ultrafiltration or peritoneal dialysis.

  3. Myoclonus in renal failure: Two cases of gabapentin toxicity

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Gabapentin, an AED approved for the adjunctive treatment of partial seizures with/without secondary generalization and for the treatment of postherpetic neuralgia, is frequently used off-label for the treatment of both psychiatric and pain disorders. Since gabapentin is cleared solely by renal excretion, dosing requires consideration of the patient's renal function. Myoclonic activity may occur as a complication of gabapentin toxicity, especially with acute kidney injury or end-stage renal disease. We report 2 cases of myoclonic activity associated with gabapentin toxicity in the setting of renal disease which resolved with discontinuation of gabapentin and treatment with hemodialysis and peritoneal dialysis. As gabapentin has multiple indications and off-label uses, an understanding of myoclonus, neurotoxicity, and renal dosing is important to clinicians in multiple specialties.

    Full Text Available Sudden cardiac death continues to be a major public health problem. Ventricular arrhythmia is a main cause of sudden cardiac death. The present review addresses the links between renal function tests, several laboratory markers, and ventricular arrhythmia risk in patients with renal disease, undergoing or not hemodialysis or renal transplant, focusing on recent clinical studies. Therapy of hypokalemia, hypocalcemia, and hypomagnesemia should be an emergency and performed simultaneously under electrocardiographic monitoring in patients with renal failure. Serum phosphates and iron, PTH level, renal function, hemoglobin and hematocrit, pH, inflammatory markers, proteinuria and microalbuminuria, and osmolarity should be monitored, besides standard 12-lead ECG, in order to prevent ventricular arrhythmia and sudden cardiac death.

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

    Full Text Available Impaired mineral homeostasis and inflammation are hallmarks of chronic kidney disease (CKD, yet the underlying mechanisms of electrolyte regulation during CKD are still unclear. Here, we applied two different murine models, partial nephrectomy and adenine-enriched dietary intervention, to induce kidney failure and to investigate the subsequent impact on systemic and local renal factors involved in Ca(2+ and Pi regulation. Our results demonstrated that both experimental models induce features of CKD, as reflected by uremia, and elevated renal neutrophil gelatinase-associated lipocalin (NGAL expression. In our model kidney failure was associated with polyuria, hypercalcemia and elevated urinary Ca(2+ excretion. In accordance, CKD augmented systemic PTH and affected the FGF23-αklotho-vitamin-D axis by elevating circulatory FGF23 levels and reducing renal αklotho expression. Interestingly, renal FGF23 expression was also induced by inflammatory stimuli directly. Renal expression of Cyp27b1, but not Cyp24a1, and blood levels of 1,25-dihydroxy vitamin D3 were significantly elevated in both models. Furthermore, kidney failure was characterized by enhanced renal expression of the transient receptor potential cation channel subfamily V member 5 (TRPV5, calbindin-D28k, and sodium-dependent Pi transporter type 2b (NaPi2b, whereas the renal expression of sodium-dependent Pi transporter type 2a (NaPi2a and type 3 (PIT2 were reduced. Together, our data indicates two different models of experimental kidney failure comparably associate with disturbed FGF23-αklotho-vitamin-D signalling and a deregulated electrolyte homeostasis. Moreover, this study identifies local tubular, possibly inflammation- or PTH- and/or FGF23-associated, adaptive mechanisms, impacting on Ca(2+/Pi homeostasis, hence enabling new opportunities to target electrolyte disturbances that emerge as a consequence of CKD development.

    Full Text Available AIMS Can Doppler index–RI be a predictor of renal colics impending obstruction in acute and emergency clinical settings. To compare the results of RI in cases of obstructive, nondilated and normal kidneys. METHODS A total of 90 patients were included in this prospective study. The patients were grouped into three categories based on the clinical settings. Group 1 with acute unilateral obstruction were 44, group 2 who were presented with flank pain without stone disease were 26 and group 3 were 20 patients with sonologically normal kidneys. Grey scale ultrasonography and colour Doppler study carried out in all the groups and index – RI value were compared. RESULTS The study showed differences in RI values among the groups (0.726±0.04, 0.63±0.039 and 0.608±0.03 respectively. CONCLUSION In acute and emergency clinical setting, grey scale ultrasonography and interrogation with colour Doppler index– RI improved the assessment and detection of impending obstructive uropathy.

    Acute cardiogenic pulmonary edema and cardiogenic shock are two of the main forms of presentation of acute heart failure. Both entities are serious, with high mortality, and require early diagnosis and prompt and aggressive management. Acute pulmonary edema is due to the passage of fluid through the alveolarcapillary membrane and is usually the result of an acute cardiac episode. Correct evaluation and clinical identification of the process is essential in the management of acute pulmonary edema. The initial aim of treatment is to ensure hemodynamic stability and to correct hypoxemia. Other measures that can be used are vasodilators such as nitroglycerin, loop diuretics and, in specific instances, opioids. Cardiogenic shock is characterized by sustained hypoperfusion, pulmonary wedge pressure > 18 mmHg and a cardiac index 30 mmHg) and absent or reduced diuresis (shock associated with ischaemic heart disease.

    Acute heart failure remains a major cause of morbidity, and its treatment requires an increasing investment of the health care system. Whereas success in treating chronic heart failure has been achieved over the last decades, several pharmacological approaches for acute heart failure have been introduced but have failed to demonstrate any clinical benefit. Serelaxin is a recombinant human relaxin-2 vasoactive peptide that causes systemic and renal vasodilation. Data suggest that the clinical benefits may be attributable to a potential combination of multiple actions of serelaxin, including improving systemic, cardiac, and renal hemodynamics, and protecting cells and organs from damage via neurohormonal, anti-inflammatory, antiremodeling, antifibrotic, anti-ischemic, and proangiogenic effects. Recently, a number of clinical trials have demonstrated that serelaxin infusion over 48 hours improved dyspnea with more rapid relief of congestion during the first days after admission for heart failure. In addition, administration of serelaxin diminished cardiac, renal, and hepatic damage, which were associated with improved long-term mortality. Available data support substantial clinical benefits and significant promise for serelaxin as a treatment option for patients with acute heart failure. This review focuses on the pharmacology and mechanisms of action of serelaxin and provides a detailed discussion of the clinical evidence for this novel therapy in acute heart failure. PMID:26331289

    Full Text Available A 17-year-old male was transferred to the pediatric intensive care unit for evaluation of acute liver failure. He was recently released from an alcohol treatment center with acute onset of chest pain. Cardiac workup was negative but he was found to have abnormal coagulation studies and elevated liver transaminases. Other evaluations included a normal toxicology screen and negative acetaminophen level. Autoimmune and infectious workups were normal providing no identifiable cause of his acute liver failure. He initially denied any ingestions or illicit drug use but on further query he admitted taking niacin in an attempt to obscure the results of an upcoming drug test. Niacin has been touted on the Internet as an aid to help pass urine drug tests though there is no evidence to support this practice. Niacin toxicity has been associated with serious multisystem organ failure and fulminant hepatic failure requiring liver transplantation. Pediatric providers should be aware of the risks associated with niacin toxicity and other experimental medical therapies that may be described on the Internet or other nonreputable sources.

    2010-10-01

    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.

    Many geriatric patients with multimorbidities have an increased risk for impaired renal function due to age and often the presence of comorbidities, such as diabetes mellitus, hypertension and heart failure. This impairment in kidney function in turn necessitates adjustments in drug therapy. A successful strategy for treating these patients includes treatment of the underlying diseases, a comprehensive review of the indications, selection of appropriate pharmacotherapeutic alternatives and for some drugs dose adjustment to the renal function. To achieve therapeutic success many patient individual factors, such as potentially complex medication regimens, polypharmacy, cognitive function and functional disabilities need to be considered when prescribing medications. This article describes the problems associated with drug therapy that is not adjusted to renal function and provides guidelines for assessment of the benefits and risks in patients with kidney failure. The characteristic features of geriatric patients in particular are considered and discussed. PMID:27447457

    Full Text Available Background and Objectives: Renal failure patients show significant impairment on measures of attention and memory, and consistently perform significantly better on neuropsychological measures of memory and attention, approximately 24 hours after hemodialysis treatment. The objectives are to determine the cognitive dysfunction in patients with renal failure requiring hemodialysis. Materials and Methods: A total of 60 subjects comprising of 30 renal failure patients and 30 controls were recruited. The sample was matched for age, sex, and socioeconomic status. The tools used were the Standardized Mini-Mental State Examination and the Brief Cognitive Rating Scale. Results: The patients showed high cognitive dysfunction in the pre-dialysis group, in all the five dimensions (concentration, recent memory, past memory, orientation and functioning, and self-care, and the least in the 24-hour post dialysis group. This difference was found to be statistically significant (P=0.001. Conclusion: Patients with renal failure exhibited pronounced cognitive impairment and these functions significantly improved after the introduction of hemodialysis.

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

    2012-01-01

    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.

    Full Text Available The clinicopathological findings of cerebral edema were investigated in patients with acute hepatic failure autopsied at Okayama University Hospital between 1970 and 1980 retrospectively. Nine (64% of 14 hepatic failure cases were found to have cerebral edema during a post-mortem examination of the brain. Clinical features of the patients with cerebral edema were not significantly different from those of the patients without cerebral edema. However, general convulsions were observed more frequently in patients later found to have cerebral edema. Moreover, the length of time from deep coma to death was much shorter in the brain edema cases with cerebral herniation than without herniation.

    Acute renal infarction is an uncommon and under-diagnosed disease. Its clinical presentation is nonspecific and often mimics other more common disease entities. The diagnosis is usually missed or delayed, which frequently results in irreversible renal parenchyma damage. High index of suspicion is required for early diagnosis, as timely intervention may prevent loss of kidney function. We report a case of acute renal infarction following coronary angiography in a patient with paroxysmal atrial fibrillation who initially presented with acute abdominal pain mimicking appendicitis.

    2016-03-01

    Renal transplantation is the best therapeutic option for end-stage chronic renal disease. Assuming that it is more advisable if performed early, we aimed to show the clinical, social, and economic advantages in 70% of our patients who were dialyzed only for a short period. For this purpose, we retrospectively collected data over 28 years in 142 kidney transplants performed in patients with sports, and reproduction. Immunosuppression consisted of 3 drugs, including steroids, cyclosporine, and azathioprine or mycophenolate. The cost in the 1st year, including patient and donor evaluation, surgery, immunosuppression, and follow-up, was $13,300 USD versus $22,320 for hemodialysis. We conclude that preemptive renal transplantation with <6 weeks on dialysis is the best therapeutic option for end-stage renal failure, especially in developing countries such as Bolivia, where until last year, full public support for renal replacement therapy was unavailable.

    Spontaneous tumor lysis syndrome is a rare initial presentation of hematologic malignancy in children that typically presents with complications of electrolyte derangement, specifically hyperkalemia, hyperphosphatemia, and hyperuricemia. We report a case of a 5-year-old boy who presented to the emergency department with gross hematuria, abdominal pain, and vomiting and was ultimately diagnosed with uric acid nephrolithiasis and acute renal failure secondary to spontaneous tumor lysis syndrome in the setting of T-cell acute lymphoblastic leukemia. Tumor lysis syndrome is considered an oncologic emergency, and in this case, the child required urgent treatment with potassium-binding agents, rasburicase, and hemodialysis. This case demonstrates that occult hematologic malignancy should be suspected in cases of nephrolithiasis and acute renal failure when found in conjunction with hyperuricemia despite a normal complete blood count at the time of presentation.

    Full Text Available A hemodiálise é uma modalidade terapêutica que pode sustentar a vida do paciente com insuficiência renal aguda (IRA, enquanto este recupera a função renal. Para sua realização, é necessário estabelecer circulação extracorpórea, para que seja realizada a filtração do sangue, impondo a necessidade de um acesso vascular viável e eficiente. O objetivo deste estudo foi avaliar a eficiência e as complicações do acesso vascular para hemodiálise (HD, com cateter temporário de duplo lúmen inserido na veia jugular externa. Foram estudados 10 cães com IRA induzida por gentamicina, submetidos a sessões diárias de HD, com duração de uma hora, até a recuperação da função renal ou óbito. Foram realizadas 104 sessões de HD nos animais estudados, observando-se necessidade de troca do cateter em sete sessões (6,7%, devido à obstrução do lúmen do cateter em seis sessões (5,8% ou por saída acidental do mesmo em uma sessão (1,0%. Não se observou migração do cateter, infecção, hemorragia ou hematoma no local de entrada do cateter na pele, obtendo-se fluxo sanguíneo patente em 90,4% das sessões. Concluiu-se que o acesso vascular na veia jugular externa com cateter temporário de duplo-lúmen mostrou-se viável, com ocorrência de poucas complicações, sendo, portanto, indicado como forma de acesso para a circulação extracorpórea para HD em cães com IRA.Hemodialysis is a therapeutic procedure that can sustain the patient's life in acute renal failure (ARF, during the renal function recover.

    Objective To explore the risk factors of complication of acute renal failure (ARF) in war injuries of limbs. Methods The clinical data of 352 patients with limb injuries admitted to 303 Hospital of PLA from 1968 to 2002 were retrospectively analyzed. The patients were divided into ARF group (n=9) and non-ARF group ( n=343) according to the occurrence of ARF, and the case-control study was carried out. Ten factors which might lead to death were analyzed by logistic regression to screen the risk factors for ARF,including causes of trauma, shock after injury, time of admission to hospital after injury, injured sites, combined trauma, number of surgical procedures, presence of foreign matters, features of fractures, amputation, and tourniquet time. Results Fifteen of the 352 patients died (4.3%) , among them 7 patients (46.7%) died of ARF, 3 (20.0%) of pulmonary embolism, 3 (20.0 %) of gas gangrene,and 2 (13.3%) of multiple organ failure. Univariate analysis revealed that the shock, time before admitted to hospital, amputation and tourniquet time were the risk factors for ARF in the wounded with limb injuries, while the logistic regression analysis showed only amputation was the risk factor for ARF ( P<0.05). Conclusion ARF is the primary cause-of-death in the wounded with limb injury.Prompt and accurate treatment and optimal time for amputation may be beneficial to decreasing the incidence and mortality of ARF in the wounded with severe limb injury and ischemic necrosis.%目的 探讨四肢战创伤并发急性肾衰竭(ARF)的危险因素.方法 回顾性分析1968-2002年收治的352例四肢战创伤患者,根据是否发生ARF将患者分为ARF组(9例)和非ARF组(343例)并进行病例对照研究,选择可能影响患者死亡的10个因素(致伤物、伤后是否休克、伤后入院时间、受伤部位、有无合并伤、手术次数、有否异物存留、骨折性质、是否截肢、止血带时间)进行logistic回归分析,筛

    Given the shortage of organs transplantation, some strategies have been adopted by the transplant community to increase the supply of organs. One strategy is the use of expanded criteria for donors, that is, donors aged >60 years or 50 and 59 years, and meeting two or more of the following criteria: history of hypertension, terminal serum creatinine >1.5mg/dL, and stroke as the donor´s cause of death. In this review, emphasis was placed on the use of donors with acute renal failure, a condition considered by many as a contraindication for organ acceptance and therefore one of the main causes for kidney discard. Since these are well-selected donors and with no chronic diseases, such as hypertension, renal disease, or diabetes, many studies showed that the use of donors with acute renal failure should be encouraged, because, in general, acute renal dysfunction is reversible. Although most studies demonstrated these grafts have more delayed function, the results of graft and patient survival after transplant are very similar to those with the use of standard donors. Clinical and morphological findings of donors, the use of machine perfusion, and analysis of its parameters, especially intrarenal resistance, are important tools to support decision-making when considering the supply of organs with renal dysfunction.

    Acute renal impairment (ARI) secondary to immersion and near-drowning is rarely described and poorly understood. A retrospective case-control study was performed: (1) to determine the incidence of ARI associated with near-drowning or immersion and (2) to define the clinical syndrome and to assess clinical predictors of ARI. Of 30 patients presenting after immersion or near-drowning, 50% were identified with ARI, with a mean admission serum creatinine of 0.24 +/- 0.33 mmol/L (2.7 +/- 3.7 mg/dl). These patients were a heterogeneous group: Eight had mild reversible ARI, three had ARI related to shock and multisystem failure, two had rhabdomyolysis-related ARI, and two had severe isolated ARI. Two patients required supportive hemodialysis and two died. Patients with ARI experienced more marked acidosis than control patients, as measured by serum bicarbonate (P drowning and is a heterogeneous condition. Although mild reversible renal impairment (serum creatinine drowning or immersion should be assessed for potential ARI by serial estimations of serum creatinine, particularly when there is an increase in the initial serum creatinine, marked metabolic acidosis, an abnormal urinalysis, or a significant lymphocytosis.

    Acute kidney injury (AKI) in the ICU frequently requires costly supportive therapies, has high morbidity, and its long-term prognosis is not as good as it has been presumed so far. Consequently, AKI generates a significant burden for the healthcare system. The problem is that AKI lacks an effective treatment and the best approach relies on early secondary prevention. Therefore, to facilitate early diagnosis, a broader definition of AKI should be established, and a marker with more sensitivity and early-detection capacity than serum creatinine - the most common marker of AKI - should be identified. Fortunately, new classification systems (RIFLE, AKIN or KDIGO) have been developed to solve these problems, and the discovery of new biomarkers for kidney injury will hopefully change the way we approach renal patients. As a first step, the concept of renal failure has changed from being a "static" disease to being a "dynamic process" that requires continuous evaluation of kidney function adapted to the reality of the ICU patient.

    2008-12-01

    The article aims to present an overview of the existing knowledge on advanced glycation end products (AGE). They are moieties that bind to proteins, but also lipids and nuclear acids. AGE are formed during glycation and oxidative stress. Accumulation of AGE occurs especially in diabetes and chronic renal failure and plays a major pathogenetic role. The deleterious effects of AGE result from cross-linking of proteins and activation of the receptor for advanced glycation end products. AGE accumulation can be noninvasively assessed by the skin autofluorescence reader. In diabetics, the skin autofluorescence predicts cardiac mortality and the occurrence of macro- and microvascular complications. In patients on haemodialysis, skin autofluorescence is highly elevated and predicts mortality. After renal transplantation AGE accumulation is lower than during haemodialysis, but still remains elevated and is a strong risk factor for chronic renal transplant dysfunction. Some of the potential methods to intervene with AGE accumulation are discussed in this article.

    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.

    Full Text Available Acute kidney injury (AKI independently increases morbidity and mortality in children admitted to the hospital. Renal replacement therapy (RRT is an essential therapy in the setting of AKI and fluid overload. The decision to initiate RRT is complex and often complicated by concerns related to patient hemodynamic and thermodynamic instability. The choice of which RRT modality to use depends on numerous criteria that are both patient and treatment center specific. Surprisingly, despite decades of use, no randomized, controlled trial study involving RRT in pediatrics has been performed. Because of these factors, clear-cut consensus is lacking regarding key questions surrounding RRT delivery. In this paper, we will summarize existing data concerning RRT use in children. We discuss the major modalities and the data-driven specifics of each, followed by controversies in RRT. As no standard of care is in widespread use for RRT in AKI or in multiorgan disease, we conclude in this paper that prospective studies of RRT are needed to identify best practice guidelines.

    Full Text Available Genes involved in acute rejection (AR after organ transplantation remain to be further elucidated. In a previous work we have demonstrated the under-expression of VE-Cadherin by endothelial cells (EC in AR following murine and human heart transplantation. Serial sections from 15 human kidney Banff-graded transplant biopsies were examined for the presence of VE-Cadherin and CD34 staining by immunohistochemistry (no AR (n=5, AR grade IA (n=5, or AR grade IIA (n=5. Quantification of peritubular EC staining were evaluated and results were expressed by the percentage of stained cells per surface analysed. There was no difference in CD34 staining between the 3 groups. VE-Cadherin expression was significantly reduced in AR Grade IIA when compared to no AR (P=.01 and to AR grade IA (P=.02. This study demonstrates a reduced VE-Cadherin expression by EC in AR after renal transplantation. The down-regulation of VE-Cadherin may strongly participate in human AR.

    Full Text Available Alberto Palazzuoli, Susanna Benincasa, Stefanie Grothgar, Pasquale Di Sipio, Giovanni Paganini, Marco Pellegrini, Ranuccio NutiDepartment of Internal Medicine and Metabolic Diseases, Cardiology Section, Le Scotte Hospital, University of Siena, ItalyAbstract: Chronic kidney disease (CKD is associated with a significant increase in death and cardiovascular mortality. 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

    Oxidative stress is commonly observed in chronic renal failure patients resulting from an unbalance between overproduction of reactive oxygen species and impairement of defense mechanisms. Proteins appear as potential targets of uremia-induced oxidative stress and may undergo qualitative modifications. Proteins could be directly modified by reactive oxygen species which leads to amino acid oxydation and cross-linking. Proteins could be indirectly modified by reactive carbonyl compounds produced by glycoxidation and lipo-peroxidation. The resulting post-traductional modifications are known as carbonyl stress. In addition, thiols could be oxidized or could react with homocystein leading to homocysteinylation. Finally, tyrosin could be oxidized by myeloperoxidase leading to advanced oxidative protein products (AOPP). Oxidatively modified proteins are increased in chronic renal failure patients and may contribute to exacerbate the oxidative stress/inflammation syndrome. They have been involved in long term complications of uremia such as amyloidosis and accelerated atherosclerosis. PMID:19297289

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

    Changes in the pharmacokinetics and metabolism of sodium salicylate were studied in rabbits with acute renal failure induced by intravenous administration of uranyl nitrate hexahydrate in a dose of 0.2 mg kg-1. 14C-labelled salicylic acid, 99mTc-complex and 125I-hippuran were used to study the metabolism. The 99mTc and 125I activities were measured with a Tesla gamma counter or beta-gamma spectrometer NE 8312. The 14C activity was measured using beta spectrometer Rack beta 1219. The 99mTc activity was determined immediately after the experiment, the 14C activity was determined after 4 days. The drug concentration was determined by comparing the activities of the sample and the standard activities. (J.J.). 6 figs., 1 tab., 18 refs

    Cerebral edema is a potentially life-threatening complication of acute liver failure, the syndrome of abrupt loss of liver function in a patient with a previously healthy liver. Although the prevalence of cerebral edema appears to be decreasing, patients with rapidly progressive (hyperacute) liver...... liver failure often can be temporarily controlled by manipulating body position, increasing the degree of sedation, and increasing blood osmolarity through pharmacologic means. However, these maneuvers often postpone, but do not eliminate, the risk of brainstem herniation unless orthotopic liver...... transplantation or spontaneous liver regeneration follows in short order. To buy time, the induction of therapeutic hypothermia (core temperature 32 degrees C-35 degrees C) has been shown to effectively bridge patients to transplant.

    The clinical manifestation of renal vein thrombosis varies with the speed and degree of venous occlusion. Such patients may be asymptomatic, have minor nonspecific symptoms such as nausea or weakness, or have more specific symptoms such as upper abdominal pain, flank pain, or hematuria. Acute scrotal pain is a very uncommon clinical expression of renal vein thrombosis. Here, we report a case of membranous glomerulonephritis-induced renal vein thrombosis presented with the symptom of acute scrotal pain caused by thrombosis-induced varicocele. This case report suggests that renal vein thrombosis should be considered in the diagnosis of acute scrotal pain; it also emphasizes that an investigation of retroperitoneum should be performed for adult patients with the sudden onset of varicocele.

    Acute liver failure (ALF) is a rare and severe liver disease that usually develops in 8 weeks or less in individuals without preexisting liver disease. Its chief causes worldwide are hepatitis virus infections (hepatitis A, B, and E) and drug hepatotoxicity (particularly intentional or unintentional acetaminophen toxicity). Massive hepatic necrosis is often seen in liver specimens in ALF and features marked loss of hepatocytes, variable degrees of inflammation, and a stereotypic proliferation of bile ductular structures (neocholangioles) derived from activated periportal hepatic progenitor cells. This paper reviews the liver pathology in ALF, including forms of zonal necrosis and their etiologies. PMID:27058243

    Full Text Available Acute kidney injury (AKI is a recognised complication of intravenous pentamidine therapy. A direct nephrotoxic effect leading to acute tubular necrosis has been postulated. We report a case of severe renal allograft dysfunction due to nebulised pentamidine. The patient presented with repeated episodes of AKI without obvious cause and acute tubular necrosis only on renal histology. Nebulised pentamidine was used monthly as prophylaxis for Pneumocystis jirovecii pneumonia, and administration preceded the creatinine rise on each occasion. Graft function stabilised following discontinuation of the drug. This is the first report of nebulized pentamidine-induced reversible nephrotoxicity in a kidney allograft. This diagnosis should be considered in a case of unexplained acute renal allograft dysfunction.

    Renal digoxin clearance was compared in patients suffering from atrial fibrillation with well preserved cardiac function (n = 9; salt intake +/- 170 mmol daily) and patients with chronic congestive heart failure (n = 10; salt intake 50 mmol daily and maintenance treatment with diuretics). There was no difference between the groups concerning digoxin dosage, creatinine clearance, diuresis or sodium excretion in the urine. Digoxin clearance in chronic heart failure proved to be significantly lower than in atrial fibrillation (48 +/- 21 vs 71 +/- 36 ml X min-1, p less than 0.05), and Cdig/Ccreat was similarly reduced at 0.73 +/- 0.15 compared to 1.09 +/- 0.27 (p less than 0.005). Steady state serum digoxin concentration was significantly higher in patients with congestive heart failure (1.44 +/- 0.47 vs 0.87 +/- 0.33 micrograms X 1(-1), p less than 0.01). Chronic congestive heart failure is a state with reduced digoxin clearance by the kidney, which could lead to digoxin intoxication not explicable by overdose, reduced renal function or the effect of interacting drugs.

Debido a la hipertensión en insuficiencia renal, se debe medir la misma en todos los perros sospechosos. La determinación de la presión arterial, común en humanos, no lo es en veterinaria, debido a la disposición anatómica de los miembros y a la baja intensidad de los sonidos producidos por la onda de pulso.

    BACKGROUND: Acute liver failure (ALF) remains a dramatic and unpredictable disease with high morbidity and mortality. Early and accurate prognostic assessment of patients with ALF is critically important for optimum clinical pathway. DATA SOURCES: Five English-language medical databases, MEDLINE, ScienceDirect, OVID, Springer Link and Wiley Interscience were searched for articles on"acute liver failure","prognosis", and related topics. RESULTS: Multi-variable prognostic models including the King's College Hospital criteria and the model for end-stage liver disease score have been widely used in determination of the prognosis of ALF, but the results are far from satisfactory. Other prognostic indicators including serum Gc-globulin, arterial blood lactate, serum phosphate, arterial blood ammonia, and serum alpha-fetoprotein are promising but await further assessement. CONCLUSIONS: A reliable prognostic model to be developed in the future should not only have predictive value for poor outcome but also help to predict the survival of patients without a liver transplantation. Further studies are necessary to assess the prognostic accuracy of any new models.

    2016-01-01

    Acute respiratory failure (ARF) is a leading indication for performing critical care ultrasonography (CCUS) which, in these patients, combines critical care echocardiography (CCE) and chest ultrasonography. CCE is ideally suited to guide the diagnostic work-up in patients presenting with ARF since it allows the assessment of left ventricular filling pressure and pulmonary artery pressure, and the identification of a potential underlying cardiopathy. In addition, CCE precisely depicts the consequences of pulmonary vascular lesions on right ventricular function and helps in adjusting the ventilator settings in patients sustaining moderate-to-severe acute respiratory distress syndrome. Similarly, CCE helps in identifying patients at high risk of ventilator weaning failure, depicts the mechanisms of weaning pulmonary edema in those patients who fail a spontaneous breathing trial, and guides tailored therapeutic strategy. In all these clinical settings, CCE provides unparalleled information on both the efficacy and tolerance of therapeutic changes. Chest ultrasonography provides further insights into pleural and lung abnormalities associated with ARF, irrespective of its origin. It also allows the assessment of the effects of treatment on lung aeration or pleural effusions. The major limitation of lung ultrasonography is that it is currently based on a qualitative approach in the absence of standardized quantification parameters. CCE combined with chest ultrasonography rapidly provides highly relevant information in patients sustaining ARF. A pragmatic strategy based on the serial use of CCUS for the management of patients presenting with ARF of various origins is detailed in the present manuscript. PMID:27524204

    BACKGROUND: Osteopontin (OPN) is a novel phosphoglycoprotein expressed in Kupffer cells that plays a pivotal role in activating natural killer cells, neutrophils and macrophages. Measuring plasma OPN levels in patients with acute liver failure (ALF) might provide insights into OPN function...... in the setting of massive hepatocyte injury. METHODS: OPN levels were measured using a Quantikine® ELISA assay on plasma from 105 consecutive ALF patients enrolled by the US Acute Liver Failure Study Group, as well as controls including 40 with rheumatoid arthritis (RA) and 35 healthy subjects both before, and 1....../mL; range 2.6-86.4). RA and SF post op patients had elevated OPN levels (37ng/mL and 198ng/mL respectively), well below those of the ALF patients. Median OPN levels were highest in acetaminophen (3603ng/mL) and ischemia-related ALF (4102ng/mL) as opposed to viral hepatitis (706ng/mL), drug-induced liver...

    2004-01-01

    Systemic hypertension is hypothesized to cause renal injury to dogs. This study was performed on dogs with surgically induced renal failure to determine whether hypertension was associated with altered renal function or morphology. Mean arterial pressure (MAP), heart rate (HR), systolic arterial pressure (SAP), and diastolic arterial pressure (DAP) were measured before and after surgery. Glomerular filtration rate (GFR) and urine protein:creatinine ratios (UPC) were measured at 1, 12, 24, 36, and 56-69 weeks after surgery, and renal histology was evaluated terminally. The mean of weekly MAP, SAP, and DAP measurements for each dog over the 1st 26 weeks was used to rank dogs on the basis of MAP, SAP, or DAP values. A statistically significant association was found between systemic arterial pressure ranking and ranked measures of adverse renal responses. When dogs were divided into higher pressure and lower pressure groups on the basis of SAP, group 1 (higher pressure, n = 9) compared with group 2 (lower pressure, n = 10) had significantly lower GFR values at 36 and 56-69 weeks; higher UPC values at 12 and 56-69 weeks; and higher kidney lesion scores for mesangial matrix, tubule damage, and fibrosis. When dogs were divided on MAP and DAP values, group 1 compared with group 2 had significantly lower GFR values at 12, 24, 36, and 56-69 weeks; higher UPC values at 12 and 56-69 weeks; and higher kidney lesion scores for mesangial matrix, tubule damage, fibrosis, and cell infiltrate. These results demonstrate an association between increased systemic arterial pressure and renal injury. Results from this study might apply to dogs with some types of naturally occurring renal failure.

  11. Managing acute and chronic renal stone disease.

    2016-02-01

    Nephrolithiasis, or renal stone disease, is common and the incidence is increasing globally. In the UK the lifetime risk is estimated to be 8-10%. On a population level, the increase in stone incidence, erosion of gender disparity, and younger age of onset is likely to reflect increasing prevalence of obesity and a Western diet with a high intake of animal protein and salt. Stones can be detected by a variety of imaging techniques. The gold standard is a non-contrast CT of kidneys, ureters and bladder (CT KUB) which can identify > 99% of stones. CT KUB should be the primary mode of imaging for all patients with colic unless contraindicated. In such instances, or if a CT KUB is not available, an ultrasound KUB is an alternative. This has advantages in terms of radiation exposure and cost, but is limited in sensitivity, particularly for ureteric stones. Once diagnosed, a plain film KUB can be used for follow-up of radiopaque stones. For most patients diclofenac is a reasonable first choice of analgesia, e.g. 50-100 mg rectally, or 75 mg IM. Opioid medication can worsen nausea and be less effective, but should be used if there is a contraindication to NSAIDs. A combination of diclofenac, paracetamol, and/or codeine regularly can provide adequate pain control in many cases. Failure of this analgesic combination should prompt consideration of secondary care support. If a ureteric stone 10 mm in diameter should be discussed with the urology service as they are unlikely to pass spontaneously. PMID:27032222

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

    Full Text Available Abstract Background Acute renal failure is a common complication of severe malaria in adults, and without renal replacement therapy (RRT, it carries a poor prognosis. Even when RRT is available, delaying its initiation may increase mortality. Earlier identification of patients who will need RRT may improve outcomes. Method Prospectively collected data from two intervention studies in adults with severe malaria were analysed focusing on laboratory features on presentation and their association with a later requirement for RRT. In particular, laboratory indices of acute tubular necrosis (ATN and acute kidney injury (AKI that are used in other settings were examined. Results Data from 163 patients were available for analysis. Whether or not the patients should have received RRT (a retrospective assessment determined by three independent reviewers was used as the reference. Forty-three (26.4% patients met criteria for dialysis, but only 19 (44.2% were able to receive this intervention due to the limited availability of RRT. Patients with impaired renal function on admission (creatinine clearance Conclusions In adult patients with severe malaria and impaired renal function on admission, none of the evaluated laboratory indices was superior to the plasma creatinine level when used to predict a later requirement for renal replacement therapy.

    Acute-on-chronic liver failure is a characteristic clinical liver syndrome, which should be differentiated from acute liver failure, acute decompensated liver cirrhosis and chronic liver failure. The pathogenesis of ACLF is not fully understood yet. Viral factors and immune injury have been reported to be the two major pathogenesis. This paper reviewed the researches on the pathogenesis of acute on chronic hepatitis B liver failure in recent years, to provide theoretical basis for prompt and accurate diagnosis and treatment of this syndrome. This would beneift for the prognosis and raise the survival rate of patients.

    Full Text Available Abstract Background Severe renal manifestation of systemic lupus erythematosus (SLE is not uncommon and is associated with an indeterminate prognosis. Complete remission can be obtained, however, at least in the young when chronic lesions are absent and adequate anti-inflammatory therapy is immediately initiated. Case presentation We report the unusual case of a 12-year-old girl who presented with severe oliguric renal failure, macrohematuria and skin rash. Renal biopsy revealed the diagnosis of severe diffuse proliferative glomerulonephritis (GN with cellular crescents in 15 out of 18 glomeruli and full-house pattern in immunofluorescence indicating lupus nephritis IVB according to WHO, IV-G(A according to ISN/RPS classification. The serological parameters confirmed the diagnosis of SLE and the patient was immediately treated with methylprednisolone, cyclophosphamide and immunoadsorption. Initially, despite rapid amelioration of her general condition, no substantial improvement of renal function could be achieved and the patient needed hemodialysis treatment for 12 weeks. Unexpectedly, in the further follow-up at first diuresis increased and thereafter also creatinine levels substantially declined so that hemodialysis could be discontinued. Today, 6 years after the initial presentation, the patient has normal renal function and a SLEDAI score of 0 under a continuous immunosuppressive therapy with Mycophenolate mofetil (MMF and low dose steroid. Conclusion Despite the severity of the initial renal injury and the unfavourable renal prognosis the kidney apparently has a tremendous capacity to recover in young patients when the damage is acute and adequate anti-inflammatory therapy is initiated without delay.

    The usefulness of the renal scan in diagnosing technical complications in the transplant patient is well established. However, the ability of the renal scan to differentiate between acute rejection and acute tubular necrosis has remained uncertain. We have evaluated the effectiveness of the /sup 99m/Tc DTPA computer-derived time-activity curve of renal cortical perfusion, as well as data obtained from scintillation camera images, in making such diagnoses. Fifteen patients with a clinical diagnosis of either acute rejection or acute tubular necrosis, or both, were studied retrospectively. Technetium scan diagnoses did not agree with the clinical assessment in nine of the patients. Thus selection of a course of treatment should not be based on data obtained from the scan alone.

    Objective To understand the clinical value of pre-operative general evaluation on therapeutic protocol selection in pa-tients with acute renal failure induced by ureteral calculus obstruction. Methods 86 patients defined as acute renal failure induced by ureteral calculus obstruction were assigned into safe group(11 -15 points),risk group(7 -10 points) and dangerous group(< 7points) according to the biochemistry indexes, conditions of ureteral obstruction and hydronephrosis. Patients in safe group and dangerous group respectively underwent urgent surgery and post-hemodialysis surgery. Patients in risk group underwent either urgent surgery or post-hemodialysis surgery, according to patients' situation. Following up for 1 month after surgery, to evaluate the situation of renal function recovery,ureteral obstruction and hydronephrosis in patients. Results In safe group, renal function were completely recovery, while reteral obstruction and hydronephrosis were completely relieved. In risk group,renal function were completely recovery, while there were one patient with ureteral obstruction and one patient with hydronephrosis. There were four patients with mild renal impairment in dangerous group. Two patients of them were with ureteral obstruction, and the other two of them were with hydronephrosis. Conclusion Pre-operative general evaluation was of great value on the selection of therapeutic protocol in patients with acute renal failure inducded by ureteral calculus obstruction.%目的 探讨术前综合评价对输尿管结石梗阻急性肾衰竭患者治疗方案选择的临床价值.方法 收集确诊为输尿管结石梗阻急性肾衰竭患者86例,依据患者生化指标、输尿管梗阻和肾积水梗阻情况,分为安全组(11~15分),风险组(7~10分)和危险组(<7分).安全组患者予立即行手术治疗;风险组患者根据患者情况予血液透析后行手术治疗或予急诊手术治疗;危险组患者予血液透析后

    Kidney allografts induce strong T-cell and antibody responses which mediate acute rejection. Spleen tyrosine kinase (Syk) is expressed by most leucocytes, except mature T cells, and is involved in intracellular signalling following activation of the Fcγ-receptor, B-cell receptor and some integrins. A role for Syk signalling has been established in antibody-dependent native kidney disease, but little is known of Syk in acute renal allograft rejection. Sprague-Dawley rats underwent bilateral nephrectomy and received an orthotopic Wistar renal allograft. Recipient rats were treated with a Syk inhibitor (CC0482417, 30 mg/kg/bid), or vehicle, from 1 h before surgery until being killed 5 days later. Vehicle-treated recipients developed severe allograft failure with marked histologic damage in association with dense leucocyte infiltration (T cells, macrophages, neutrophils and NK cells) and deposition of IgM, IgG and C3. Immunostaining identified Syk expression by many infiltrating leucocytes. CC0482417 treatment significantly improved allograft function and reduced histologic damage, although allograft injury was still clearly evident. CC0482417 failed to prevent T-cell infiltration and activation within the allograft. However, CC0482417 significantly attenuated acute tubular necrosis, infiltration of macrophages and neutrophils and thrombosis of peritubular capillaries. In conclusion, this study identifies a role for Syk in acute renal allograft rejection. Syk inhibition may be a useful addition to T-cell-based immunotherapy in renal transplantation.

  3. An Epidermolysis Bullosa Patient Complicated with Chronic Renal Failure

    2013-03-01

    Full Text Available A 32-yr-old man with epidermolysis bullosa presented with clinical and laboratory findings of chronic renal failure. The patient was supposed to be suffering from mesangial IgA glomerulonephritis in view of the repeated persistent macroscopic episodes of hematuria and raised serum IgA levels, especially polimeric IgA. Because continuous vascular access could not be established, the patient died due to uremia and sepsis. Renal complications are associated with life-threatening problems in this inherited mechanobullous disease because it is impossible to obtain a continuous vascular access or a continuous peritoneal access. The possibility of IgA nephropathy should be considered in patients with epidermolysis bullosa. They should be periodically set up screened for IgA levels and hematuria.

    The most common causes of end stage renal failure in 46 children (mean age 11 years, range 4-14) treated between January 1972 and June 1977 were: reflux nephropathy (n = 12), cystinosis (n = 7), focal and segmental glomerulosclerosis (n = 6), and Schönlein-Henoch disease (n = 5). The quality of life, degree of renal function, and height attainment of the 31 survivors were assessed in June 1985, when their mean age was 22 years (range 14-27), using hospital records and a questionnaire designed to highlight social and psychological problems. Twenty six patients had a functioning transplanted kidney. Average growth during treatment for all survivors was normal, but most were disappointed with their 'final height'. Though five patients had some form of disabling bone disease, all 31 could walk and 27 could run. Sixteen (67%) were in full or part time employment and nine were living independently. A group of 32 patients with juvenile onset diabetes treated at this hospital for at least five years were also asked to complete the questionnaire and of these, 17 responded. On average, their data could usefully be compared with those of cases of end stage renal failure. More of the diabetics had jobs, but most sexually mature patients with renal disease were concerned about their physical appearance and had not achieved any stable long term sexual relationships. We suggest that a poor body image resulting in low self esteem may be responsible for the deficiency and believe that further study in this group is warranted. PMID:3126713

    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.

    Acute renal infarction is a serious medical emergency. The diagnosis is often delayed or missed as it is not common. Hence, the exact incidence of acute renal infarction is not known. Failure to consider renal infarction in the initial differential diagnosis results in a delay in diagnosis and treatment, which in turn leads to permanent loss of renal function. We present two cases of acute kidney infarction that were initially treated as renal colic. In addition, we present a third case when ...

    Neurofibromatosis (NF) is a genetic disorder of the nervous system that primarily affects the development and growth of neural cell tissues. This disorder is characterized by the development of various tumors, including neurofibromas, neuroniomas, malignant and benign peripheral nerve sheath tumors, and meningiomas. Accompanying skin changes and bone deformities are also common in NF. However, genitourinary involvement in NF is a rare condition, and penile enlargement has been reported only in a few males with plexiform NF. We report a 6-year-old boy with chronic renal failure associated with plexiform neurofibromas of the bladder and prostatic urethra which led to urinary obstruction and macrogenitalia due to genitourinary NF.

    2012-01-01

    Full Text Available A 14-year-old boy presented with asymptomatic right hydronephrosis detected on routine yearly ultrasound examination. Previously, he had at least two normal renal ultrasonograms, 4 years after remission of acute myeloblastic leukemia, treated by AML-BFM-93 protocol. A function of the right kidney and no damage on the left was confirmed by a DMSA scan. Right retroperitoneoscopic nephrectomy revealed 3 renal arteries with the lower pole artery lying on the pelviureteric junction. Histologically chronic tubulointerstitial nephritis was detected. In the pathogenesis of this severe unilateral renal damage, we suspect the exacerbation of deleterious effects of cytostatic therapy on kidneys with intermittent hydronephrosis.

    The emergence of multi-drug-resistant gram negative bacillary infections has regained popularity of ancient drugs such as polymyxins. We report a case of acute respiratory failure induced by use of intravenous colistimethate, which is one of the forms of polymyxin. The patient is a 31 year old female with paraplegia due to spina bifida who underwent excisional debridement of large lumbosacral decubitus ulcer with osteomyelitis infected with pan-resistant Pseudomonas aeruginosa and MRSA. Six days after initiation of intravenous colistimethate and vancomycin, she developed acute respiratory failure requiring mechanical ventilation. Pan-culture was negative including a chest radiograph. V/Q scan showed low probability for pulmonary embolism. Echocardiogram showed normal right ventricle with no strain or pulmonary hypertension. Colistimethate was discontinued. Within 24 hours, she was extubated. In the early years after introduction of polymyxin, there were several reports of acute respiratory paralysis. The mechanism is thought to be noncompetitive myoneuronal presynaptic blockade of acetylcholine release. Though a direct causal relationship for respiratory failure is often difficult to establish in current era with multiple co morbidities, the timeframe of apnea, acuity of onset as well as rapid recovery in our case clearly point out the causal relationship. In addition, our patient also developed acute renal failure, presumably due to colistimethate induced nephrotoxicity, a possible contributing factor for her acute respiratory failure. In summary, colistimethate can induce acute neurotoxicity including respiratory muscular weakness and acute respiratory failure. Clinicians should consider its toxicity in the differential diagnosis of acute respiratory failure especially in critically ill patients. PMID:25337492

    A case of Red-bellied Black snake envenomation resulting in intravascular haemolytic anaemia, rhabdomyolysis and anuric renal failure is described in the dog. A 12-year-old female desexed Golden Retriever was presented with a 15 hour history of profuse salivation, progressive lethargy, obtundence, inappetence and collapse. Significant findings on clinical examination were pallor, icterus, tachypnoea and dyspnoea with increased respiratory sounds and crackles in all lung fields. Generalised abdominal and muscular pain was apparent and dark red-brown urine was present around the perineal region. A diagnosis of Red-bellied Black snake (Pseudechis porphyriacus) envenomation was made and the dog was treated with intravenous fluid therapy, Tiger/Brown snake antivenom, packed red cell transfusions and Intermittent Positive Pressure Ventilation. Continued clinical deterioration occurred and a diagnosis of acute renal failure secondary to myohaemoglobinuric pigmenturia was made 12 hours after admission. Intensive treatment was attempted with diuresis and volume expansion. Oliguria and subsequent anuria ensued and the dog was euthanased due to a grave prognosis and lack of clinical response to treatment. Necropsy examination revealed muscular necrosis, accumulation of fluid in the thoracic and peritoneal cavities, and marked renal tubular necrosis with intraluminal occlusion secondary to pigmentary casts.

    Nephrotoxicity caused by contrast media and drugs is a frequent cause of renal failure in medical practice. However, there are only sporadic cases of renal failure caused by chemicals, foods, plants, animal venoms, and misused or illegal drugs, and standard medical textbooks are limited in the coverage given to the subject. This review provides a referenced compilation of these lesser-known nephrotoxins and gives an overview of renal failure caused by substances other than properly used medications.

  16. Imatinib-induced fatal acute liver failure

    2007-01-01

    Imatinib mesylate is a drug that has been approved for treatment of chronic myeloid leukemia (CML) in blast crisis, accelerated or chronic phase, and also for advanced gastrointestinal stromal tumors. Severe hepatic toxicity and three deaths from hepatic failure have been reported. We report the case of a 51-year-old woman who was admitted to our institution with severe acute hepatitis. She was diagnosed with CML and began treatment with imatinib mesylate at a dose of 400 mg/d.Five months after beginning treatment, she developed severe hepatitis associated with coagulopathy, and was admitted to our institution. She had been consuming acetaminophen 500-1000 mg/d after the onset of symptoms. She had a progressive increase in bilirubin level and a marked decrease of clotting factor Ⅴ. Five days after admission, grade Ⅱ encephalopathy developed and she was referred for liver transplantation. Her clinical condition progressively deteriorated, and 48 h after being referred for transplantation she suffered a cardiac arrest and died. This report adds concern about the possibility of imatinib-mesylate-induced hepatotoxicity and liver failure, particularly in the case of concomitant use with acetaminophen. Liver function tests should be carefully monitored during treatment and, with the appearance of any elevation of liver function tests, treatment should be discontinued.

    Chronic renal failure is often associated with multiple organ co-morbidities, including thyroid dysfunction. This has been associated with poorer prognosis, particularly in patients with end-stage renal disease. This study aimed to examine the relationship between renal failure and thyroid dysfunction in an outpatient setting at the King Abdulaziz University Hospital, Saudi Arabia, from January 2011 to June 2012. Demographic and biochemical data were extracted from medical records. Differences in the levels of thyroid hormones and lipids between the four renal function groups were analyzed using the chi-square test for categorical variables and Kruskal- Wallis test for binomial variables. A total of 486 patients were included in the study population, of whom approximately half were female, and the median (range) age was 61 (17-90) years. According to creatinine measurements, renal function was normal in 48 participants, 290 had mild renal failure, 122 had moderate renal failure and 26 had severe renal failure. No significant relationships were observed between renal failure and cardiac or pulmonary dysfunction. Free triiodothyronine (FT3) levels were significantly reduced (P = 0.005) and both free thyroxin (FT4; P = 0.034) and parathyroid hormone (PTH; P = 0.028) significantly increased with increasing severity of renal failure. Patients with moderate to severe renal failure displayed reduced hemoglobin levels and were significantly more likely to be anemic (P renal dysfunction. To conclude, it was observed that renal dysfunction is associated with notable changes to other organ systems, including the thyroid. Further studies may investigate the association of multiple organ co-morbidities with prognosis in patients with chronic renal failure.

    Full Text Available At present, the diagnosis of renal allograft rejection requires a renal biopsy. Clinical management of renal transplant patients would be improved if rapid, noninvasive and reliable biomarkers of rejection were available. This study is designed to determine whether such protein biomarkers can be found in renal-graft tissue proteomic approach. Orthotopic kidney transplantations were performed using Fisher (F344 or Lewis rats as donors and Lewis rats as recipients. Hence, there were two groups of renal transplant models: one is allograft (from F344 to Lewis rats; another is syngrafts (from Lewis to Lewis rats serving as control. Renal tissues were collected 3, 7 and 14 days after transplantation. As many as 18 samples were analyzed by 2-D Electrophoresis and mass spectrometry (MALDI-TOF-TOF-MS. Eleven differentially expressed proteins were identified between groups. In conclusion, proteomic technology can detect renal tissue proteins associated with acute renal allograft rejection. Identification of these proteins as diagnostic markers for rejection in patients′ urine or sera may be useful and non-invasive, and these proteins might serve as novel therapeutic targets that also help to improve the understanding of mechanism of renal rejection.

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

    Full Text Available Chronic renal failure (CRF is one of the best known renal diseases. It is characterized by a deterioration in the overall renal function and is associated with other conditions such as hypertension, diabetes mellitus, uropathy, chronic glomerulonephritis and autoimmune diseases. Patients with CRF show alterations of the masticatory system that are specific to the disease and other type of disorders as a result of treatment. Oral health in dialysis and transplant patients tends to be poor, which makes them more likely to develop pathological conditions in the oral cavity, potentially increasing morbidity, mortality and affecting the quality of life of patients. Among the lesions we can find dysgeusia, periodontitis, candidiasis, gingival bleeding, petechiae, and joint alterations. Gingivitis and xerostomia associated to long-term use medications can cause oral lesions. Children with CRF show two oral conditions of interest: high incidence of dental anomalies and low caries activity. In patients receiving a kidney transplant, previous dental treatment is critical because the immune status of the patient will be affected not only by the toxemia, but by the immunosuppressive drugs used to prevent organ 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 Introduction:There is scarce information regarding clinical evolution of HBV infection in renal transplant patients.Aims:To evaluate the prevalence of acute exacerbation in HBV-infected renal transplant patients and its association with the time after transplantation, presence of viral replication, clinical evolution, and use of antiviral prophylaxis.Materials and methods:HBV infected renal transplant patients who underwent regular follow-up visits at 6-month intervals were included in the study. The criteria adopted to characterize exacerbation were: ALT >5 × ULN and/or >3 × baseline level. Predictive factors of exacerbation evaluated were age, gender, time on dialysis, type of donor, post-transplant time, ALT, HBeAg, HBV-DNA, HCV-RNA, immunosuppressive therapy, and use of antiviral prophylaxis.Results:140 HBV-infected renal transplant patients were included (71% males; age 46 ±10 years; post-renal transplant time 8 ±5 years. During follow-up, 25% (35/140 of the patients presented exacerbation within 3.4 ±3 years after renal transplant. Viral replication was observed in all patients with exacerbation. Clinical and/or laboratory signs of hepatic insufficiency were present in 17% (6/35 of the patients. Three patients died as a consequence of liver failure. In univariate analysis variables associated with exacerbation were less frequent use of prophylactic/preemptive lamivudine and of mycophenolate mofetil. Lamivudine use was the only variable independently associated with exacerbation, with a protective effect.Conclusions:Acute exacerbation was a frequent and severe event in HBV-infected renal transplant patients. Prophylactic/preemptive therapy with antiviral drugs should be indicated for all HBsAg-positive renal transplant patients.

    The effect of transient renal ischemia on renal concentration and distribution of /sup 99m/Tc-HEDP, /sup 99m/Tc-DMSA, and /sup 99m/Tc-DTPA was compared in rabbits with acute tubular necrosis. Scintigrams were obtained after injection in normal rabbits or ones with unilateral or bilateral ischemia. /sup 99m/Tc-HEDP concentration in ischemic tissue was 8 to 18 times normal 1 to 4 hrs after injection, and the resulting images delineated the morphological changes in the ischemic kidneys more accurately than those obtained with DMSA or DTPA. Calcium concentration in the ischemic kidneys increased sixfold. /sup 99m/Tc-HEDP may be useful in evaluation of renal failure secondary to tubular injury

    International Nuclear Information System (INIS)

    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.

    Background Invasive kidney biopsy is a priority diagnostic method for the acute rejection after renal transplantation for the past decades. However, no effective and noninvasive assay for predicting the severity of acute rejection is in wide use at present. This study was designed to investigate the predictive value of programmed death 1 (PD-1) mRNA for acute rejection after renal transplantation with real-time reverse transcriptase polymerase chain reaction (RT-PCR). A noninvasive diagnostic method has been expected to replace the tranditional kidney biopsy for the diagnosis of acute rejection and prediction of the outcome after kidney transplantation.Methods The whole blood samples from 19 subjects with acute rejection, 20 subjects with delayed graft function (DGF)and 21 subjects with stable recipients after kidney transplantation in a single kidney transplantation center between 2006 and 2009 were collected. The messenger RNA (mRNA) of PD-1 was analyzed with real-time RT-PCR. The associations of PD-1 mRNA levels with acute rejection and disease severity were investigated.Results The log-transformed ratio of PD-1 mRNA to GAPDH mRNA was higher in peripheral blood mononuclear cell (PBMC) from the group with acute rejection (4.52±1.1) than that from the group with DGF (1.12±0.6) or the group with normal biopsy results (0.7±0.4) (P <0.01, by the Kruskal-Wallis test). PD-1 mRNA levels were correlated with serum creatinine levels measured at the time of biopsy in the acute rejection group (Spearman's correlation coefficient, r=0.81,P=0.03), but not in the group with DGF or the group with normal biopsy results. PD-1 mRNA levels identified subjects at risk for graft failure within six months after the incident episode of acute rejection.Conclusions Our data suggest that PD-1 status may be a new predictor of acute rejection and the levels of PD-1mRNA in whole blood cells may positively correlate with the severity of acute rejection after renal transplantation

    Acute renal injury caused by acute necrotizing pancreatitis (ANP) is a common complication that is associated with a high rate of mortality. Paeoniflorin is the active ingredient of paeonia radix and exhibits a number of pharmacological effects, such as anti‑inflammatory, anticancer, analgesic and immunomodulatory effects. The present study detected the potential treatment effects of paeoniflorin on acute renal injury induced by ANP in a rat model. The optimal dose of paeoniflorin for preventing acute renal injury induced by ANP was determined. Then, the possible protective mechanism of paeoniflorin was investigated. The serum levels of tumor necrosis factor (TNF)‑α, interleukin (IL)‑1β and IL‑6 were measured with enzyme‑linked immunosorbent assay kits. Renal inflammation and apoptosis were measured by immunohistochemistry and terminal deoxynucleotidyl transferase‑mediated dUTP nick end labeling assay. The expression of nitric oxide in kidney tissues was also evaluated. The p38 mitogen‑activated protein kinases (MAPKs) were measured by western blotting. The results shown that paeoniflorin may ameliorate acute renal injury following ANP in rats by inhibiting inflammatory responses and renal cell apoptosis.

    Acute liver failure (ALF) is defined by the presence of coagulopathy (International Normalized Ratio ≥ 1.5) and hepatic encephalopathy due to severe liver damage in patients without pre-existing liver disease. Although the mortality due to ALF without liver transplantation is over 80%, the survival rates of patients have considerably improved with the advent of liver transplantation, up to 60% to 90% in the last two decades. Recent large studies in Western countries reported 1, 5, and 10-year patient survival rates after liver transplantation for ALF of approximately 80%, 70%, and 65%, respectively. Living donor liver transplantation (LDLT), which has mainly evolved in Asian countries where organ availability from deceased donors is extremely scarce, has also improved the survival rate of ALF patients in these regions. According to recent reports, the overall survival rate of adult ALF patients who underwent LDLT ranges from 60% to 90%. Although there is still controversy regarding the graft type, optimal graft volume, and ethical issues, LDLT has become an established treatment option for ALF in areas where the use of deceased donor organs is severely restricted.

    2015-09-03

    Current goals in the acute treatment of heart failure are focused on pulmonary and systemic decongestion with loop diuretics as the cornerstone of therapy. Despite rapid relief of symptoms in patients with acute decompensated heart failure, after intravenous use of loop diuretics, the use of these agents has been consistently associated with adverse events, including hypokalemia, azotemia, hypotension, and increased mortality. Two recent randomized trials have shown that continuous infusions of loop diuretics did not offer benefit but were associated with adverse events, including hyponatremia, prolonged hospital stay, and increased rate of readmissions. This is probably due to the limitations of congestion evaluation as well as to the deleterious effects linked to drug administration, particularly at higher dosage. The impaired renal function often associated with this treatment is not extensively explored and could deserve more specific studies. Several questions remain to be answered about the best diuretic modality administration, global clinical impact during acute and post-discharge period, and the role of renal function deterioration during treatment. Thus, if loop diuretics are a necessary part of the treatment for acute heart failure, then there must be an approach that allows personalization of therapy for optimal benefit and avoidance of adverse events.

    Objective To explore the correlation between the serum cystatin C levels in patients with acute renal failure (ARF) and the disease severity. Methods Convenient selection a total of 150 cases of patients with ARF as the research objects who were cured in our hospital between June 2013—June 2015 and 30 cases of healthy persons as control group were selected. The concentration of cystatin C and serum creatinine (Scr) in these patients were detected by using ELISA method. According to the acute physiology and chronic health score III (APACHE III) system, patients with ARF were divid-ed into five groups. The relationship between cystatin C level and APACHE III score was analyzed. Results Cystatin C level in ARF patients was significantly higher than that in control group [(3.1±0.8) mg/L vs (1.1±0.2)]. It was positively correlated with APACHE III score. Conclusion Elevated serum C cystatin level can be used as a biological indicator to judge the severity of ARF, and cystatin C can be used to monitor the condition of ARF.%目的:探讨急性肾衰竭(acute renal failure, ARF)患者血清胱抑素C(cystatin C)水平与病情危重程度相关性。方法方便选取郑州颐和医院该院从2013年6月—2015年6月收治的150例ARF患者,30名健康体检者作对照组,使用ELISA法检测受试者中血清cystatin C和血肌酐(serum creatinine, Scr)浓度;根据急性生理与慢性健康状况评分Ⅲ(acute physiology and chronic health evaluation Ⅲ, APACHE Ⅲ)系统评分将ARF患者分为5组(每组30例)并分析cystatin C水平与5组患者的APACHEⅢ评分的关系。结果 ARF患者血清cystatin C水平显著高于对照组[(3.1±0.8) vs (1.1±0.2) mg/L],并与APACHEⅢ评分呈正相关。结论血清cystatin C水平升高可以作为判断ARF病情加重的一项生物指标,可以使用cystatin C对急性肾损伤病情进行监测。

    Rapid and reliable biomarkers of renal allograft rejection have not been available. This study aimed to investigate biomarkers in renal allograft tissue using proteomic analysis. Orthotopic kidney transplantations were performed using Fisher (F344) or Lewis rats as donors and Lewis rats as recipients. Syngenic control group (Group I) constituted F344-to-F344 orthotopic kidney allo-transplantations (n = 8); and allogenic group (Group II) consisted of F344-to-Lewis orthotopic kidney allo-transplantations (n = 8). Renal tissues were harvested 7 days after transplantation. Samples were analyzed using 2-D electrophoresis and matrix assisted laser desorption ionization-time of flight mass spectrometry. 6 differentially expressed proteins were identified between allogenic group and syngenic control group. A rat model of acute renal allograft rejection was successfully set up. Differentially expressed proteins in renal allograft tissue of rat were detected using proteomic analysis and might serve as novel diagnostic and therapeutic targets in human. Quantitative proteomics, using MALDL-TOF-MS methodology has the potential to provide a profiling and a deeper understanding of acute renal rejection.

    Objective: To evaluate the prevalence of renal failure (RF) in the patients of end stage liver disease (ESLD), to determine the causes of RF in these patients and its impact on patient's outcome. Study Design: Descriptive, analytical study. Place and Duration of Study: Shifa International Hospital, Islamabad, Pakistan, from May 2011 to March 2013. Methodology: A total of 523 patients with end stage liver disease (ESLD) were evaluated, renal failure (RF) and its causes were recognized in these patients according to established criteria. Outcome of these patients was assigned as reversal of RF or mortality. Data was analyzed using SPSS version 16. Chi-square test was used for comparing proportions and t-test was used for comparing mean values. P < 0.05 was considered significant. Results: Out of 523 patients, 261 (49.9%) had RF. Acute kidney injury (AKI) was the most common presentation seen in 160 (61%) patients. Hypovolemia and infections were the most frequent causes of RF. Mortality was significantly higher in the patients with RF, when compared to the patients without RF (31% vs. 4.5%, p < 0.001). Reversal of RF was seen in 98 (37%) of the affected patients. Reversal was more common in the patients with hypovolemia. The mortality was higher in the patients with hepatorenal syndrome (HRS) and infections. Conclusion: Renal failure in the end stage liver disease is an important prognostic factor. Etiology of RF is the key factor in patients' outcome. Patients of ESLD with RF had higher mortality. Majority of the cases of RF were reversible in patients of ESLD coming in the setup. (author)

    Hyperhomocysteinemia, a risk factor for vascular disease, is commonly found in adult patients with end-stage renal disease. Major determinants of elevated plasma homocysteine levels in these patients include deficiencies in folate and vitamin B12, methylenetetrahydrofolate reductase (MTHFR) genotype and renal function. Little information is available for children with chronic renal failure (CRF). The prevalence and the factors that affect plasma homocysteine concentration were determined in children. Twenty-nine children with various degrees of CRF (15 were dialyzed, 14 were not dialyzed) were compared with 57 age- and sex-matched healthy children. Homocysteine concentrations were higher in patients than controls (17.3 micromol/l vs 6.8 micromol/l, P95th percentile for controls: 14.0 micromol/l) was seen in 62.0% of patients and 5.2% of controls. Folate concentrations were lower in patients (9.9 nmol/l) than controls (13.5 nmol/l), P<0.01. Vitamin B12 was similar in patients (322 pmol/l) and controls (284 pmol/l). Dialyzed patients have a higher prevalence of hyperhomocysteinemia than nondialyzed patients (87% vs 35%). Dialyzed patients with MTHFR mutation have higher plasma homocysteine (28.5 micromol/l) than nondialyzed patients with the mutation (10.7 micromol/l), P<0.002. In our study, differences between controls and patients in plasma homocysteine concentrations are observed when age is greater then 92 months, folate less than 21.6 nmol/l and vitamin B12 less than 522 pmol/l. Our study shows that hyperhomocysteinemia is common in children with CRF and is associated with low folate and normal vitamin B12 status, compared to normal children. Among the patients, the dialyzed patients with the MTHFR mutation are particularly at risk for hyperhomocysteinemia. Further studies are needed to investigate therapeutic interventions and the potential link with vascular complications in these patients. PMID:11605787

    The authors report on a rare case of neonatal scrotal oedema occurring concurrently with pain upon palpation of the spermatic cord on the first day of life. An ultrasound examination showed poor perfusion of the left testicle and a thrombosis of the left renal vein; intraoperative exploration indicated necrosis of the left testicle without signs of torsion. Gorged vessels with paravasal bleeding were found in the spermatic cord. The authors hypothesise that necrosis of the testicle may result from haemorrhagic infarction caused by renal venous thrombosis. Acute scrotal discolouration with pain upon palpation in neonates is usually attributed to testicular torsion. The authors report a case where these symptoms had a different cause.

    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.

    2011-01-01

    It has been consistently observed that patients with renal dysfunction have more premature, severe, complicated, and fatal cardiovascular disease than age- and sex-matched individuals with normal renal function. There have been 4 major explanations for this finding: (1) positive confounding by third variables associated with chronic kidney disease (CKD), including diabetes mellitus and hypertension; (2) therapeutic nihilism or lesser use of beneficial therapies in CKD; (3) greater toxicities of therapies, such as bleeding from anticoagulants or contrast-induced kidney injury; (4) biological factors which result directly from CKD that work to promote and accelerate cardiovascular disease. In this paper, we focus on the issue of treatment disparities or therapeutic nihilism and its contribution to poor outcomes in the setting of acute coronary syndromes and acutely decompensated heart failure. This issue is important because if we can overcome barriers to the utilization of beneficial treatments, then clinical outcomes should improve over time. PMID:21625092

    2015-02-01

    Hepatic encephalopathy in a hospitalized cirrhotic patient is associated with a high mortality rate and its presence adds further to the mortality of patients with acute-on-chronic liver failure (ACLF). The exact pathophysiological mechanisms of HE in this group of patients are unclear but hyperammonemia, systemic inflammation (including sepsis, bacterial translocation, and insulin resistance) and oxidative stress, modulated by glutaminase gene alteration, remain as key factors. Moreover, alcohol misuse, hyponatremia, renal insufficiency, and microbiota are actively explored. HE diagnosis requires exclusion of other causes of neurological, metabolic and psychiatric dysfunction. Hospitalization in the ICU should be considered in every patient with overt HE, but particularly if this is associated with ACLF. Precipitating factors should be identified and treated as required. Evidence-based specific management options are limited to bowel cleansing and non-absorbable antibiotics. Ammonia lowering drugs, such as glycerol phenylbutyrate and ornithine phenylacetate show promise but are still in clinical trials. Albumin dialysis may be useful in refractory cases. Antibiotics, prebiotics, and treatment of diabetes reduce systemic inflammation. Where possible and not contraindicated, large portal-systemic shunts may be embolized but liver transplantation is the most definitive step in the management of HE in this setting. HE in patients with ACLF appears to be clinically and pathophysiologically distinct from that of acute decompensation and requires further studies and characterization.

  16. Acute Systolic Heart Failure Associated with Complement-Mediated Hemolytic Uremic Syndrome

    John L. Vaughn

    2015-01-01

    Full Text Available Complement-mediated hemolytic uremic syndrome (otherwise known as atypical HUS is a rare disorder of uncontrolled complement activation that may be associated with heart failure. We report the case of a 49-year-old female with no history of heart disease who presented with microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury. Given her normal ADAMSTS13 activity, evidence of increased complement activation, and renal biopsy showing evidence of thrombotic microangiopathy, she was diagnosed with complement-mediated HUS. She subsequently developed acute hypoxemic respiratory failure secondary to pulmonary edema requiring intubation and mechanical ventilation. A transthoracic echocardiogram showed evidence of a Takotsubo cardiomyopathy with an estimated left ventricular ejection fraction of 20%, though ischemic cardiomyopathy could not be ruled out. Treatment was initiated with eculizumab. After several failed attempts at extubation, she eventually underwent tracheotomy. She also required hemodialysis to improve her uremia and hypervolemia. After seven weeks of hospitalization and five doses of eculizumab, her renal function and respiratory status improved, and she was discharged in stable condition on room air and independent of hemodialysis. Our case illustrates a rare association between acute systolic heart failure and complement-mediated HUS and highlights the potential of eculizumab in stabilizing even the most critically-ill patients with complement-mediated disease.

    Full Text Available The present paper describes a case of spontaneous hemocholecyst in a patient with end-stage renal failure on low molecular weight heparin hemodialysis. The patient presented with acute right upper quadrant pain. An initial ultrasound scan demonstrated a distended gallbladder containing echogenic bile without stones. During hospitalization the patient became febrile, and jaundiced, developed leukocytosis, and had an elevation in serum bilirubin, transaminases, and alkaline phosphatase. A new ultrasound demonstrated a thick-walled gallbladder containing echogenic bile and pericholecystic fluid. MRI depicted a distended gallbladder containing material of mixed signal intensity and a normal biliary tract. Open cholecystectomy revealed a gallbladder filled with blood and clots, and transcystic common bile duct exploration flushed blood clots out of the bile duct. To our knowledge this is the second case of spontaneous hemocholecyst reported in the literature as a consequence of uremic bleeding and LMWH hemodialysis in the absence of other pathology.

    Full Text Available A thirty-five-year-old Sudanese woman (gravida 4, para 3, at 34 weeks gestational age, presented with snakebite in her right leg. Examination of the cardiovascular, respiratory, gastrointestinal, and central nervous systems revealed no abnormalities. Her blood urea was 58 mg/dl; creatinine, 2.6 mg/dl; whole blood clotting time, 5:35 minutes. The patient was diagnosed as having acute renal failure and was then managed conservatively. She received polyvalent antivenom serum intravenously. On the next day, she delivered prematurely and the baby passed away due to respiratory distress. There was no postpartum bleeding and the patient's clotting time was 5:30 minutes. She was discharged from the hospital after 7 days when her clinical, biochemical and hematological parameters returned to normal values without dialysis.

Methods Eleven cases were treated with retrograded catheterizations of ureter with semi-rigid ureteroscopy (F6.8) and 2 cases were treated with. The renal function was followed up in these pa- tients. Results Only 1 patient got anuria and whose haemoglobin continued to drop postoperatively. This patient underwent a redo operation and peritoneal dialysis. The other 12 patients recovered well. The renal function of all the 13 children got back to normal without surgical complications. Conclusions The technique of retrograded catheterization of ureters under ureteroscope was a minimally invasive, safe and effective therapy for infants with post renal acute renal failure by consumption of powdered milk contaminated by melamine. For those infants whose urethras are thin and small, is also an effec- tive method, But the bleeding tendency should be corrected before open.

  1. Functional renal failure (FRF) in cirrhosis of the liver and liver carcinoma

    1975-01-01

    The term ‘functional renal failure’ has been used to describe the renal failure developing in advanced cirrhosis in which tubular function and structure remain intact. It may develop spontaneously, in which case prognosis is poor, but may be secondary to gastro-intestinal haemorrhage or excessive use of diuretics, in which case correction of the precipitating factor leads to improvement in renal function. It is suggested that the renal failure is due to a reduction in effective circulating plasma volume. PMID:1234327

    Millions of Americans regularly use herbal supplements, but many are unaware of the potential hidden dangers. Numerous supplements have been associated with hepatotoxicity and, indeed dietary/herbal supplements represent an increasingly common source of acute liver injury. We report a case of acute liver failure requiring liver transplantation associated with the use of Garcinia cambogia, a supplement widely promoted for weight loss. When patients present with acute hepatitis or liver failure from an unknown etiology, a careful history of supplement use should be performed. PMID:26626648

    Glenoid loosening is the most common cause of failure in primary total shoulder arthroplasty (TSA) and often occurs years after the initial surgery. It is rare for a glenoid component to fail acutely. Several case reports of complete glenoid dissociation appear in the literature. It is important to report these failures to identify technical errors or component design flaws to improve outcomes in TSA. In this case report, we present an unrecognized acute failure of a cemented hybrid glenoid component at the time of surgery. PMID:27555976

    Neuropeptide Y (NPY) is coreleased with norepinephrine and stimulates vasoconstriction, vascular and cardiomyocyte hypertrophy via Y1 receptors (R) and angiogenesis via Y2R. Although circulating NPY is elevated in heart failure, NPY's role remains unclear. Activation of the NPY system was determined in Wistar rats with the aortocaval (A-V) fistula model of high-output heart failure. Plasma NPY levels were elevated in A-V fistula animals (115.7 +/- 15.3 vs. 63.1 +/- 17.4 pM in sham, P renal failure (urinary Na(+) excretion renal blood flow (RBF), and death within 5-7 days (DECOMP). Cardiac and renal tissue NPY decreased with heart failure, proportionate to the severity of renal complications. Cardiac and renal Y1R mRNA expression also decreased (1.5-fold, P failure. In contrast, Y2R expression increased up to 72-fold in the heart and 5.7-fold in the kidney (P failure and cardiac hypertrophy. Changes in receptor expression were confirmed since the Y1R agonist, [Leu31, Pro34]-NPY, had no effect on RBF, whereas the Y2R agonist (13-36)-NPY increased RBF to compensate for disease. Thus, in this model of heart failure, cardiac and renal NPY Y1 receptors decrease and Y2 receptors increase, suggesting an increased effect of NPY on the receptors involved in cardiac remodeling and angiogenesis, and highlighting an important regulatory role of NPY in congestive heart failure.

    A 77-year-old male was hospitalized due to haematuria and developed septicaemia. He received dabigatran due to chronic atrial fibrillation. Doses were reduced because of renal failure according to guidelines. The patient showed extensive changes in his entire coagulation system. Due to renal...... failure forced diuresis was not possible, and continuous dialysis was performed. Patients with renal failure should be monitored closely - if there are any sign of bleeding it is important to consider change of anticoagulant therapy as long as an antidote does not exist....

    A 65-year-old male in the dilated phase of hypertrophic cardiomyopathy and with persistent atrial fibrillation was admitted to our hospital because of an episode of ventricular fibrillation following an appropriate shock from an implantable cardiac defibrillator (ICD). At admission, electrocardiography showed a normal sinus rhythm. He had complained of back pain 7 days after the ICD shock. Renal infarction was suspected, although computed tomography and magnetic resonance imaging could not be performed because of chronic renal failure and the presence of his ICD. We, therefore, used contrast-enhanced ultrasonography with a contrast agent to evaluate his acute kidney injury. This showed the left kidney contained a wedge-shaped area that was not enhanced by the contrast agent, indicating an area of infarction.

    2016-01-01

    AL amyloidosis is a clonal plasma cell proliferative disorder characterised by extracellular tissue deposits of insoluble fibrils derived from κ or λ immunoglobulin light chains. The most common organs affected by AL amyloidosis are the kidney, presenting with nephrotic syndrome and/or progressive renal dysfunction, and the heart, with restrictive cardiomyopathy. Hepatic deposition of fibrils occurs in half the cases but the liver is rarely the predominantly affected organ. The most common presentation of hepatic amyloidosis is hepatomegaly with elevated alkaline phosphatase. Acute liver failure with cholestasis and jaundice is a rare complication, with a prevalence of approximately 5%, and is usually associated with a worse prognosis. We report a case of a 39-year-old man admitted to our nephrology department with an unusual presentation of primary amyloidosis with nephrotic syndrome and acute liver failure, complicated by obstructive cholestasis resulting in death 2 months after diagnosis.

    2004-01-01

    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.

    The objectives of this study were to define the acute and chronic effects of 1-hour unilateral in vivo renal ischemia on renal function and histology in cats. Twenty-one adult purpose-bred research cats were anesthetized, and 1 kidney underwent renal artery and vein occlusion for 1 hour. Serum creatinine and urea concentrations, urine protein:creatinine ratio, urine-specific gravity, glomerular filtration rate, hematocrit, platelet concentration and function, and white blood cell count were measured at baseline and variable time points after ischemia. Renal histopathology was evaluated on days 3, 6, 12, 21, 42, and 70 postischemia; changes in smooth muscle actin and interstitial collagen were examined. Following ischemia, whole animal glomerular filtration rate was significantly reduced (57% of baseline on day 6; P cats and demonstrates that ischemic acute kidney injury triggers chronic fibrosis, interstitial inflammation, and tubular atrophy in feline kidneys. These late changes are typical of those observed in cats with naturally occurring chronic kidney disease. PMID:26319781

    Full Text Available ABSTRACTThe incidence of chronic renal failure (CRF is on the increase in Nigeria. This study on the effect of CRF on lipid profile is carried out in CRF patients on dialysis treatment. A total of 100 subjects (both male and female were used for the study. 50 of them were apparently healthy, while the remaining 50 were CRF patients on dialysis. The levels of triglyceride (TG, total cholesterol (TC, high density lipoprotein – cholesterol (HDL-C, low density lipoprotein- cholesterol (LDL-C and very low density lipoprotein –cholesterol (VLDL-L were estimated using enzymatic methods. Their cardiovascular risk indices (TC/HDL-C and LDL-C/HDL-C were also determined.The results indicated that all the parameters were significantly (p<0.05 altered in both sexes when compared with their counterparts in the control group. The cardiovascular risk indices, TC/HDL-C and LDL-C/HDL-C of the CRF patients were higher than those of the control group.In conclusion, the CRF patients on dialysis are at risk of developing cardiovascular disease.

  14. Turnover of VLDL-apoliporprotein b in chronic renal failure

    International Nuclear Information System (INIS)

    Chronic renal failure (CRF) has been known to be associated with apolipoprotein (Apo) and lipid abnormalities, leading to accelerated atherosclerosis (AS). This work is aimed at studying the lipoprotein (LP) metabolism of CRF patients in order to elucidate how this metabolism is linked with AS. The fractional synthesis rate (FSR) of ApoB in very low density lipoprotein (vLDL) was determined by using endogenous 15N-glycine labeling and GC-MS analysis in 5 patients with CRF. Plasma lipid profiles of CRF patients were also studied. The FSR of vLDL-ApoB obtained by this method was 3.19 ± 0.43%/day in CRF patients, while that in the normal subjects (5.6 ± 0.45%/day) was significantly higher (P<0.0001). The CRF patients also had reduced levels of HDL-cholesterol (34.6 ± 4.6% mg/dl) in comparison with the control (63.2 ± 4.6 mg/dl)

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

    Renal impairment influences the prognosis of patients with cardiovascular disease and increases cardiovascular risk. Renal dysfunction is a marker of lesions in other parts of the vascular tree and detection facilitates early identification of individuals at high risk of cardiovascular events. In patients with cardiovascular disease, renal function is assessed by measuring albuminuria in a spot urine sample and by estimating the glomerular filtration rate using creatinine-derived predictive formulas or equations. We recommend the Chronic Kidney Disease Epidemiology Collaboration or the Modification of Diet in Renal Disease formulas. The Cockcroft-Gault formula is a possible alternative. The administration of drugs that block the angiotensin-renin system can, on occasion, be associated with acute renal dysfunction or hyperkalemia. We need to know when risk of these complications exists so as to provide the best possible treatment: prevention. Given the growing number of diagnostic and therapeutic procedures in the field of cardiology that use intravenous contrast media, contrast-induced nephrotoxicity represents a significant problem. We should identify the risk factors and patients at greatest risk, and prevent it from appearing.

    Renal toxicity is a hallmark of uranium exposure, with uranium accumulating specifically in the S3 segment of the proximal tubules causing tubular damage. As the distribution, concentration and dynamics of accumulated uranium at the cellular level is not well understood, here, we report on high-resolution quantitative in situ measurements by high-energy synchrotron radiation X-ray fluorescence analysis in renal sections from a rat model of uranium-induced acute renal toxicity. One day after subcutaneous administration of uranium acetate to male Wistar rats at a dose of 0.5 mg uranium kg(-1) body weight, uranium concentration in the S3 segment of the proximal tubules was 64.9 ± 18.2 µg g(-1) , sevenfold higher than the mean renal uranium concentration (9.7 ± 2.4 µg g(-1) ). Uranium distributed into the epithelium of the S3 segment of the proximal tubules and highly concentrated uranium (50-fold above mean renal concentration) in micro-regions was found near the nuclei. These uranium levels were maintained up to 8 days post-administration, despite more rapid reductions in mean renal concentration. Two weeks after uranium administration, damaged areas were filled with regenerating tubules and morphological signs of tissue recovery, but areas of high uranium concentration (100-fold above mean renal concentration) were still found in the epithelium of regenerating tubules. These data indicate that site-specific accumulation of uranium in micro-regions of the S3 segment of the proximal tubules and retention of uranium in concentrated areas during recovery are characteristics of uranium behavior in the kidney.

    2016-01-01

    The number of patients developing liver failure; acute on chronic liver failure and acute liver failure continues to increase, along with the demand for donor livers for transplantation. As such there is a clinical need to develop effective extracorporeal devices to support patients with acute liver failure or acute-on-chronic liver failure to allow time for hepatocyte regeneration, and so avoiding the need for liver transplantation, or to bridge the patient to liver transplantation, and also potentially to provide symptomatic relief for patients with cirrhosis not suitable for transplantation. Currently devices can be divided into those designed to remove toxins, including plasma exchange, high permeability dialyzers and adsorption columns or membranes, coupled with replacement of plasma proteins; albumin dialysis systems; and bioartificial devices which may provide some of the biological functions of the liver. In the future we expect combinations of these devices in clinical practice, due to the developments in bioartificial scaffolds.
