Acute renal failure is a recognized manifestation of paracetamol toxicity, but comparatively little data is available concerning its onset and duration. The present study sought to characterize the time course of rising serum creatinine concentrations in paracetamol nephrotoxicity. Renal failure was defined by serum creatinine concentration ≥150 μmol/L (1.69 mg/dL) or ≥50% increase from baseline. Serum creatinine concentrations and alanine aminotransferase activity were considered with respect to the interval after paracetamol ingestion. There were 2068 patients with paracetamol overdose between March 2005 and October 2007, and paracetamol nephrotoxicity occurred in 8 (0.4%). All had significant hepatotoxicity, and peak serum alanine aminotransferase activity occurred at 2.5 days (2.2 to 2.9 days) after ingestion. Peak serum creatinine concentrations did not occur until 5.5 days (4.4 to 5.9 days) after ingestion (p = .031 by Wilcoxon test). Serum creatinine concentrations slowly restored to normal, and renal replacement was not required. In this patient series, rising serum creatinine concentrations only became detectable after more than 48 hours after paracetamol ingestion. Therefore, renal failure might easily be missed if patients are discharged home before this. Further work is required to establish the prevalence of paracetamol-induced nephrotoxicity, and its clinical significance.

Renal Uptake

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

Myoglobinuric Acute Renal Failure

We have reported previously that aminophylline has an ameliorating effect on the course and severity of glycerol-induced myoglobinuric acute renal failure in rats. Since aminophylline dissociates into theophylline in biological fluids and since theophylline is an adenosine receptor antagonist, we attributed the ameliorating effects to antagonism of the hemodynamic effects of endogenous adenosine. However, theophylline blocks tubuloglomerular feedback and produces natriuresis, and either of these effects might have accounted for the beneficial effects in acute renal failure. Therefore, this study was designed to further characterize the effects of theophylline in glycerol-induced acute renal failure in rats. Aminophylline had dose-dependent beneficial effects, as judged by the peak serum creatinine during the 3 days following induction of acute renal failure, by the number of animals with peak serum creatinine >1 mg/dL, and by the mortality rate. Both furosemide and theophylline block tubuloglomerular feedback and produce natriuresis, but aminophylline had protective effects, whereas furosemide actually increased mortality, compared with aminophylline, following induction of myoglobinuric acute renal failure. Therefore, aminophylline's protective effects are independent of tubuloglomerular feedback and natriuresis. These results offer further support for the hypothesis that adenosine-induced hemodynamic changes play a pathogenic role in glycerol-induced acute renal failure in rats.

Specific Factors

Background & Objective: Acute renal failure (AKI) is one of the most important complications of PCI. Due to delay in creatinine increase, we need specific factors to detect AKI earlier. The aim of this study is to evaluate the valuable factors by focusing on HFAB-P that can be predictive for AKI after Percutaneous Coronary Intervention (PCI). Methods: This prospective study was performed on 95 patients (55 males and 44 females aged between 49-78 years) under PCI in Golestan and Imam Khomeini hospitals in Ahvaz. Patients were divided into three groups based on the development of AKI after the procedure: no AKI, severe AKI (doubling of serum creatinine or needing dialysis) and any type of AKI (increased creatinine ≥ 0/3 mg/dl or a 50% increase in the means of 1/5 times serum creatinine). The demographic and clinical characteristics of the patients, the medical history and the results of the HFABP marker, GFR, and creatinine before and after PCI were evaluated for all patients. Results: The progenies showed 6 patients with severe AKI, 17 patients with any type of AKI, and 72 patients without AKI. Diabetes (P = 0.003), hypertension (P = 0.027), gender of patients (P = 0.025) and hospital admission days (P <0.001) were significantly different among the groups. Patients' age and positive troponin were significantly higher in patients with AKI. HFABP was the only factor that had significant changes before and after PCI (P <0.001). The cut-off value of HFABP was 4.69 with 95.6% sensitivity and 84.7% specificity. It has a good negative predictive value of 98.39% which suggests it to be a good test for the AKI prediction. Glomerular Filtration Rate (GFR) and creatinine (Cr) were significantly different after PCI (P <0.001). Conclusion: HFABP can be considered as a predictor for AKI after PCI. Moreover, our study suggests that evaluating several parameters such as Cr and GFR before and after PCI can predict the AKI development after PCI.

Objective: To determine the frequency of factors leading to acute renal failure in obstetric patients. Study Design: Cross Sectional study. Setting: Department of Obstetrics and Gynecology, Civil Hospital Karachi, Tertiary Care Hospital. Period: July 2015- Jan 2016. Material & Methods: Total 250 women during pregnancy and within 42 days after delivery who were diagnosed as ARF were included. Serum creatinine was done on admission and then after 24 hours of delievery. Those with urine output < 30ml / hour and serum creatinine > 1.5 mg / dl were recruited. All data was recorded on proforma. Results: The average age of the women was 29.36±5.87 years. Post-partum hemorrhage was the important and common factor i.e. 40.4%, followed by placental abruption 25.6%, Severe pre-eclampsia 18.4%, puerperal sepsis 8.4% and eclampsia 7.2%. Conclusion: Ante partum hemorrhage like placental abruption, eclampsia and preeclampsia, and postpartum hemorrhages’ are the major causes of obstetrical ARF. Good antenatal care and provision of universal health facility can prevent this dangerous condition. Though it is a treatable and curable complication, but if not diagnosed and treated timely, it can lead to significant maternal morbidity and mortality.

Introduction: Birth asphyxia is an eventuality having far reaching consequences in the neonatal period. Hypoxia and ischemia can cause damage to almost every tissue and organ in the body and various target organs involved. Renal insult is a recognized complication of birth asphyxia and carries a poor prognosis. Timely detection of renal dysfunction and appropriate management may favorably alter the prognosis in many neonates with birth asphyxia. Objective: The present study was done to find out the incidence of acute renal failure in the full term neonates with birth asphyxia. Methodology: A cross sectional study was conducted at Birat Medical College Teaching Hospital, Morang, Nepal from 1st September 2017 to 28th February 2018. Fifty full term neonates born with Apgar score of <6 at 5 minutes and fulfilling inclusion criteria were enrolled in the study. Asphyxiated neonates having Serum creatinine >1.5gm/dl or urine output<1ml/kg/hr were labeled as cases of Acute Renal Failure. Blood sample for serum creatinine was collected at 24hrs, 48 hrs and 72 hrs of life. Results A total of 50 term asphyxiated neonates were enrolled in the present study. Among them 54% and 46% were males and females respectively with male to female ratio of 1.2:1. In the present study 62% of cases developed acute renal failure in either of the first three days of life with mean urine output 1.02±0.27ml/kg/hr and mean serum creatinine of 1.49±0.32 mg/dL. The incidence of oliguric renal failure was 52% and non oliguric renal failure was 48%.The association between serum creatinine and urine output was statistically significant. Conclusion: In the present study birth asphyxia has been an important cause of neonatal acute renal injury, revealing 31 (62%) cases. Monitoring urine output and serum creatinine has helped in detecting the asphyxiated neonates with acute renal injury in the early stage.

Abstract We show an example of the importance of specifying the form of isoenzyme and source of indicator enzymes to be used in coupled enzymatic assays. When we compared H4 (pig heart) and M4 (rabbit muscle) isoenzymes of lactate dehydrogenase for their suitability as indicator enzymes in the assay for alanine aminotransferase activity, we found that about fourfold as much M4 as H4 was required in terms of lactate dehydrogenase activity to reflect accurately equivalent amounts of alanine aminotransferase activity. Moreover, the substrate specificities of the two isoenzymes differed quantitatively.
