1 Serial measurements of plasma mercury were made in a patient with severe and prolonged acute renal failure due to poisoning with mercuric chloride. 2 An initial mercury concentration in whole blood of 1200 μg/l (6 μmol/l) was recorded, and recovery of renal function coincided with a fall in plasma mercury concentration to below 100 μg/l (0.5 μmol/l). 3 The case demonstrates that survival and recovery of renal function is possible despite very high concentrations of mercury in the blood and oliguric renal failure of nearly six weeks' duration.

The Impact

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. Aminophylline was administered at 1 mg/kg intravenously or orally every twelve hours. Forty-six percent (n = 6) of the patients received a 5 mg/kg loading dose before initiation of maintenance therapy. Most patients had already received other treatments for renal failure, including diuretics and dopamine. RESULTS Resolution of acute renal failure (with normalization of serum creatinine and blood urea nitrogen) was documented in 10 patients (77%). Four of the thirteen patients died from complications due to their prematurity. Failure of low-dose aminophylline was observed in 3 of the 4 patients who died. CONCLUSIONS Low-dose aminophylline in neonates with acute renal failure is associated with an improvement in renal function indices.

Possible Cause

Oxalosis, or calcium oxalate deposition in the tissues, may develop in patients with inherited disorders of oxalate metabolism or can occur secondary to other diseases. In this study, a case of renal oxalosis probably secondary to excessive parenteral vitamin C administration in a patient with acute post-traumatic oliguric renal failure is reported. Oxalate deposits may have contributed to further worsening and delayed recovery of renal function. The elimination of the source of excess vitamin C and its presumed effect on oxalate production, together with enhanced removal of oxalate during aggressive dialysis, resulted in prompt recovery of renal function. Secondary oxalosis represents a possible cause of delayed recovery of renal function in patients with acute renal failure who are receiving vitamin C supplementation if excess dosage of that supplementation is given. Vitamin C supplementation, if utilized, should be carefully monitored in patients receiving artificial renal replacement therapy.

D Dimer

SummaryD dimer and other large fragments produced during the breakdown of crosslinked fibrin may be measured by enzyme immunoassay using monoclonal antibodies. In 91 patients with renal disease and varying degrees of renal dysfunction, plasma D dimer showed no correlation with renal function, whereas FgE antigen, a fibrinogen derivative which is known to be cleared in part by the kidney, showed a significant negative correlation with creatinine clearance. Plasma concentrations of D dimer were, however, increased in patients with chronic renal failure (244 ± 3l ng/ml) (mean ± SEM) and diabetic nephropathy (308 ± 74 ng/ml), when compared with healthy controls (96 ± 13 ng/ml), and grossly elevated in patients with acute renal failure (2,451 ± 1,007 ng/ml). The results indicate an increase in fibrin formation and lysis, and not simply reduced elimination of D dimer by the kidneys, and are further evidence of activated coagulation in renal disease. D dimer appears to be a useful marker of fibrin breakdown in renal failure.

Цель - исследование влияния куркумы длинной и галеги восточной на осмо- и ионорегулирующую функции почек крыс при аллоксан-индуцированном сахарном диабете и острой почечной недостаточности в эксперименте. Методика. Эксперименты выполнены на самцах крыс Wistar (n=70) с моделью сахарного диабета (1-я серия) и острой почечной недостаточности (2-я серия). В обеих сериях животные были поделены на 3 группы: крыс 1-й группы содержали на стандартном корме, крысам остальных групп в корм добавляли куркуму (2-я группа) или галегу (3-я группа) (2% от массы корма). На 7-е сут эксперимента проводили исследование диуретической и ионоуретической функций почек натощак и после 5% водной нагрузки. Концентрацию ионов в моче и плазме определяли методом пламенной фотометрии; осмотическую концентрацию биологических жидкостей - методом криоскопии; биохимические показатели крови - колориметрическим методом. Результаты. У животных с сахарным диабетом фоновый диурез, а также экскреция натрия и калия были статистически значимо выше, чем у контрольных животных. При острой почечной недостаточности наблюдался более низкий уровень диуреза и ионоуреза, особенно после водной нагрузки. Прием куркумы и галеги вызывал улучшение осмо- и ионорегулирующей функции почек у крыс с сахарным диабетом, и практически не влиял на эти функции почек при острой почечной недостаточности. Заключение. При сахарном диабете оба фитопрепарата вызывали понижение концентрации глюкозы, креатинина, мочевины и улучшение ионно-осмотических показателей плазмы крови, при этом эффект куркумы был выражен отчетливее. При острой почечной недостаточности эти фитопрепараты не давали описанного эффекта. Aim. To study effects of the phytomedicines, Curcuma longa and Galega orientalis, on osmosis- and ion-regulating renal functions in rats with experimental diabetes mellitus (DM) and acute renal failure (ARF). Methods. Experiments were performed in two series on Wistar male rats (n=70) with modeled diabetes mellitus (series 1) and acute renal failure (series 2). In each series, the animals were divided into 3 groups, 1) rats of group 1 receiving a standard diet; 2) rats of groups 2 and 3 receiving a standard diet supplemented with turmeric or galega (2% of food weight), respectively. On the 7th day of the experiment, the diuretic and ionuretic renal function was studied in fasting state and after 5% water loading. Concentrations of ions in urine and plasma were determined by flame photometry; osmotic concentrations of biological fluids were measured by cryoscopy; blood biochemical parameters were measured by colorimetry. Results. In diabetic rats, background diuresis and sodium and potassium excretion were significantly higher than in the control animals. In rats with acute renal failure, diuresis and ionuresis were significantly lower, particularly after the water loading. Turmeric and galega supplementation improved the osmotic and ion-regulating renal function in diabetic rats and left practically unchanged these functions in rats with acute renal failure. Conclusion. In rats with diabetes mellitus, both herbal remedies reduced concentrations of glucose, creatinine, and urea and improved ion-osmotic parameters of blood plasma with a more pronounced effect of turmeric. In acute renal failure, these phytomedicines did not produce the described effects.

Background The authors investigated the incidence and risk factors for postoperative acute renal failure after major noncardiac surgery among patients with previously normal renal function. Methods Adult patients undergoing major noncardiac surgery with a preoperative calculated creatinine clearance of 80 ml/min or greater were included in a prospective, observational study at a single tertiary care university hospital. Patients were followed for the development of acute renal failure (defined as a calculated creatinine clearance of 50 ml/min or less) within the first 7 postoperative days. Patient preoperative characteristics and intraoperative anesthetic management were evaluated for associations with acute renal failure. Thirty-day, 60-day, and 1-yr all-cause mortality was also evaluated. Results A total of 65,043 cases between 2003 and 2006 were reviewed. Of these, 15,102 patients met the inclusion criteria; 121 patients developed acute renal failure (0.8%), and 14 required renal replacement therapy (0.1%). Seven independent preoperative predictors were identified (P < 0.05): age, emergent surgery, liver disease, body mass index, high-risk surgery, peripheral vascular occlusive disease, and chronic obstructive pulmonary disease necessitating chronic bronchodilator therapy. Several intraoperative management variables were independent predictors of acute renal failure: total vasopressor dose administered, use of a vasopressor infusion, and diuretic administration. Acute renal failure was associated with increased 30-day, 60-day, and 1-yr all-cause mortality. Conclusions Several preoperative predictors previously reported to be associated with acute renal failure after cardiac surgery were also found to be associated with acute renal failure after noncardiac surgery. The use of vasopressor and diuretics is also associated with acute renal failure.

Ischaemia Reperfusion

We investigated whether the treatment with 17β-oestradiol has renal protective effects in male rats with ischaemic acute renal failure (ARF). We also examined if the effect of 17β-oestradiol is accompanied by suppression of enhanced endothelin-1 production in postischaemic kidneys. Ischaemic ARF was induced by clamping the left renal artery and vein for 45min followed by reperfusion, 2 weeks after contralateral nephrectomy. Renal function parameters such as blood urea nitrogen, plasma creatinine and creatinine clearance were measured to test the effectiveness of the steroid hormone. Renal function in ARF rats markedly decreased 24h after reperfusion. The ischaemia/reperfusion-induced renal dysfunction was dose-dependently improved by pretreatment with 17β-oestradiol (20 or 100µg/kg, intravenously). Histopathological examination of the kidney of untreated ARF rats revealed severe lesions, such as tubular necrosis, proteinaceous casts in tubuli and medullary congestion, all of which were markedly improved by the higher dose of 17β-oestradiol. In addition, endothelin-1 content in the kidney after the ischaemia/reperfusion increased significantly by approx. 2-fold over sham-operated rats, and this elevation was dose-dependently suppressed by the 17β-oestradiol treatment. These results suggest that oestrogen exhibits protective effects against renal dysfunction and tissue injury induced by ischaemia/reperfusion, possibly through the suppression of endothelin-1 overproduction in postischaemic kidneys.
