non oliguric acute renal failure

Haemolytic uraemic syndrome (HUS) is characterized by haemolytic anaemia, thrombocytopenia and acute renal failure. We studied the activation state of classical and alternative pathways of complement during the acute phase of Shiga toxin-associated HUS by performing a prospective study of 18 patients and 17 age-matched healthy controls to evaluate C3, C3c, C4, C4d, Bb and SC5b-9 levels. SC5b-9 levels were increased significantly in all patients at admission compared to healthy and end-stage renal disease controls, but were significantly higher in patients presenting with oliguria compared to those with preserved diuresis...

BACKGROUND: Acute kidney injury (AKI) is common in the pediatric intensive care unit (PICU). We aimed to describe the etiology, clinical features, and outcome of AKI in pediatric patients and to determine the predictors for initiation of renal replacement and mortality. METHODS: A retrospective chart review was performed of the medical records for all patients who were admitted to the PICU at King Abdulaziz University Hospital between January 1 and December 31, 2011...

INTRODUCTION: Cardiovascular comorbidities regularly determine renal function. We report a case of acute kidney injury (Acute Kidney Injury Network stage 3) due to an intermittent third-degree atrioventricular block, which had not been diagnosed before. CASE PRESENTATION: A 76-year-old Caucasian man with liver cirrhosis due to non-alcoholic fatty liver disease, and type-2 diabetes was cognitively impaired and had reduced vigilance presumably caused by hepatic encephalopathy and/or Alzheimer dementia...

Acute interstitial nephritis (AIN) is an under recognized and under diagnosed cause of acute kidney injury (AKI). It is estimated to account for 15 - 20% of cases of AKI; it is the reported diagnosis in 2.8% of all kidney biopsies, and 13.5% of biopsies done specifically for acute renal failure. Considerable evidence implicates antigen initiated cell-mediated injury in the pathogenesis of AIN. Drugs account for 70% of all cases, with over 150 different agents incriminated. The remaining cases are due to infections, autoimmune diseases, and rarely idiopathic...

Piperazine as an antihelminth has many adverse effects, especially on patients with renal insufficiency. We report the use of piperazine in a girl with a moderately severe kidney disease due to Biedl Bardet syndrome. She developed coma and acute kidney injury due to acute interstitial nephritis (AIN), anemia and thrombocytopenia. The presence of fever, proteinuria, acidosis, anemia, sterile pyuria and non-oliguric renal failure strongly suggested AIN. Her problems abated mostly by discontinuing of piperazine and supportive therapy, except anemia and thrombocytopenia...

We conducted a retrospective study of patients with severe falciparum malaria to determine factors associated with malarial acute renal failure (MARF). We reviewed 262 medical records of adults hospitalized with severe falciparum malaria in Thailand from 2004 to 2008. The incidence of MARF in our study population was 44% (115/262); 75% (86/115) of these had MARF on admission and 25% (29/115) developed MARF during hospitalization. The majority of MARF patients presented in a hypercatabolic state (62%, 68/109) and were non-oliguric (48%, 55/115) or oliguric (44%, 51/115)...

Thirst is stimulated by increases in effective plasma osmolality that are detected by cerebral osmoreceptors located in the vascular organ of the lamina terminalis. However, surgical destruction or organic lesions of the lamina terminalis decrease the sensation of thirst in response to increased plasma osmolality. A 17-year-old boy who was diagnosed with craniopharyngioma at the age of 10 years and underwent tumor resection and gamma knife surgery was admitted for non-symptomatic severe hypernatremia. Although the sodium level was 173 mmol/L and serum osmolality was also high (371 mOsm/kg), the patient did not report increased thirst...

We report the use of vancomycin laden antibiotic cement beads in a patient with calcaneal osteomyelitis who had prior acute kidney injury (AKI). The patient experienced non-oliguric renal failure after exposure to intravenous vancomycin and recovered well after antibiotic discontinuation and adequate hydration. We are not aware of any similar case report where vancomycin laden antibiotic cement has been used in a patient with AKI to vancomycin.

BACKGROUND: We studied the urinary abnormalities and acute kidney injury (AKI) as per RIFLE criteria in scrub typhus. METHODS: A prospective case record-based study of scrub typhus was carried out from January 2009 to December 2010 in a tertiary hospital in South India. Patients were followed up until renal recovery or for at least 3 months after discharge. Univariate, chi-squared tests and multivariate logistic regression analyses were performed to identify the predictors of AKI...

OBJECTIVE: Aminophylline is a methylxanthine with multiple physiologic actions. At low doses, aminophylline can antagonize adenosine and improve renal function via increased glomerular filtration rate. Despite its clinical use, little data exists in neonates for this indication. Therefore, the objective of this report is to describe the impact of aminophylline on renal function indices in a series of neonates with acute renal failure. MATERIALS AND METHODS: This was a retrospective chart review of 13 neonates with acute renal failure who received aminophylline during a 15-month study period...

Patients with haemorrhagic fever with renal syndrome (HFRS) may present without significant oliguria. We compared different initial clinical symptoms and laboratory findings in patients who developed oliguric acute renal failure (ARF) with those in patients who did not develop oliguric ARF. Overall, 128 patients with serologically confirmed HFRS were hospitalized at the University Hospital for Infectious Disease, Zagreb, Croatia between January 1999 and December 2010. Clinical signs and laboratory findings were extracted from medical charts, and were assessed for their relationship to the development of oliguric ARF...

BACKGROUND: Non-oliguric hyperkalaemia of the newborn is defined as a plasma potassium level > 6.5 mmol/L in the absence of acute renal failure. Hyperkalaemia is a common complication in the first 48 hours of life in very low birth weight (VLBW) (birth weight < 1500 g) and/or very preterm newborns (≤32 weeks gestational age). OBJECTIVES: To determine the effectiveness and safety of interventions for non-oliguric hyperkalaemia [for the purpose of this review defined as serum potassium > 6...

BACKGROUND: Estimating the dialysis dose is a requirement commonly used to assess the quality of renal replacement therapy (RRT) in patients with chronic kidney disease (CKD). In patients with acute kidney injury (AKI), this value is not always evaluated and it has been estimated that the prescribed dose is seldom obtained. Reports addressing this issue in AKI individuals are scarce and most have not included an adequate number of patients or treatments, nor were patients treated with extended therapies...

In this prospective study, we aimed to assess the clinical characteristics of acute renal failure (ARF), determine oxidative stress, as well as to predict the outcome in patients with severe falciparum malaria (FM). The study included a total of 75 subjects; there were 25 adult patients with acute severe FM and ARF, 25 adult patients with uncomplicated FM without ARF, and 25 age- and sex-matched healthy subjects who served as controls. In patients with severe FM and ARF (n = 25), renal failure was non-oliguric in 28% and oliguric in 72%...

Sodium bromate is a strong oxidant used as a neutralizing solution in hair permanents, as well as an auxiliary agent in printing and dyeing. Accidental or deliberate ingestion of bromate solution has rarely been reported in Korea. The clinical manifestations of bromate intoxication are vomiting, diarrhea, central nervous system symptoms, oliguric or non-oliguric acute kidney injury, hemolytic anemia, and deafness; most of these manifestations are reversible, with the exception of renal failure and deafness...

BACKGROUND: Exposure to the dipyridyl herbicide paraquat can cause many manifestations of toxicity, and is a common method of suicide in developing countries. CASE REPORT: We present a case of a 20 year old healthy gentleman who intentionally overdosed on paraquat in a suicide attempt. He presented to the hospital within 4 hours of ingestion. Despite standard supportive measures, the patient's clinical condition worsened. He developed ulceration of his oral mucosa...

To investigate in vivo platelet function in acute falciparum malaria plasma concentrations of β-thromboglobulin (β-TG), platelet factor 4 (PF4) and thrombospondin (TSP) were determined in 10 severely-ill Thai patients and 11 healthy volunteers. 8 patients recovered. At presentation, the platelet counts of the 10 patients were significantly lower (p < 0.025) than those of the controls, and a slight but significant increase (p < 0.05) in β-TG/PF4 ratios in the patients suggested low-grade platelet activation...

BACKGROUND: Haemolytic uraemic syndrome (HUS) is characterized by haemolytic anaemia, thrombocytopaenia and acute renal failure. The aim of this study was to investigate the levels of oxidative stress (OS) during the acute phase of HUS. METHODS: This prospective study included 18 patients diagnosed with D + HUS, 6 age-matched healthy controls and 29 children with end-stage renal disease (ESRD) not caused by HUS under regular haemodialysis. Plasma lipid peroxidation and non-enzymatic antioxidant defences were measured as thiobarbituric acid-reactive substances (TBARs) and total reactive antioxidant potential (TRAP), respectively, during hospitalization and in control individuals...

Inorganic mercury poisoning is uncommon, but when it occurs it can result in severe, life threatening features and acute renal failure. A 2-year old well thriving child presented with alleged history of accidental ingestion of inorganic mercury chloride. He presented with evidence of corrosive trauma to the gastrointestinal tract mucosa, but with normal renal function at admission, which was managed with BAL and other supportive treatment. But he developed non-oliguric renal failure after admission, which also improved gradually...

BACKGROUND: This study was designed to investigate the clinical significance of hypoalbuminemia as a marker of severity and mortality in patients with Scrub typhus. METHODS: The patients with scrub typhus were divided into two groups based on the serum albumin levels; Group I (serum albumin <3.0 g/dL) and Group II (serum albumin >or=3.0 g/dL). The outcome of patients with hypoalbuminemia was compared with that of normoalbuminemia. RESULTS: Of the total 246 patients who underwent the study, 84 patients (34...
