Acute kidney injury

Hypouricemia is a condition which refers to hyper-uric acid clearance due to a defect in renal tubular transport. It is considered as a hereditary renal problem. Patients with hereditary renal hypouricemia have a higher risk of exercise-induced acute kidney injury and reduced kidney function. Although avoiding  exercise is considered as the best preventive measure, there are many kinds of jobs that require occupational exercise. A 32-year-old male physical trainer suffered from stage 3 Acute Kidney Injury after performing a 18-m multistage shuttle run test. His father had previously been diagnosed as having renal  hypouricemia at another facility. The patient had reported having hypouricemia during a health check, but his serum uric acid concentration was within the  normal range at our hospital. After treatment, he recovered from exercise-induced acute kidney injury and exhibited low serum uric acid and hyper-uric acid  clearance. Since the patient desired to continue his career requiring strenuous exercise, it was difficult to propose a preventive plan against the recurrence of  exercise-induced acute kidney injury. Patients suffering with hereditary renal hypouricemia are at higher risk of developing Acute Kidney Injury when undergo  strenuous occupational anaerobic exercise than other workers. Hence the risks of exercise-induced acute kidney injury among patients with hypouricemia  should be considered when undergoing physical occupational training.

Hemorrhagic ascites in patients with cirrhosis is described as a RBC (Red Blood cell) >50,000/mm³ and leads to increased morbidity and mortality. Positive red blood cells at a level of less than 50,000/mm³ (10,000-50,000) may be encountered in the ascites but it is not known whether this is clinically significant or not. This study aimed to examine the outcome of hemorrhagic ascites in patients with advanced cirrhosis. Data from 329 cirrhotic patients with ascites who received paracentesis at least once due to ascites was retrospectively analyzed from the period of 2007-2013 from the Türkiye Yüksek İhtisas Hospital, Department of Gastroenterology. Patients were divided according to the number of RBC, with greater than 10,000/mm³ being described as hemorrhagic ascites, and less than 10,000 / mm³ described as the normal or control group. Patient data included: number of accepted intensive unit service stays, acute kidney injury (AKI), hepatic encephalopathy (HES), model for end-liv...

IgG is widely used for patients with immune deficiencies and in a broad range of autoimmune and inflammatory disorders. Up to 40% of intravenous infusions of IgG may be associated with adverse effects (AEs), which are mostly uncomfortable or unpleasant but often are not serious. The most common infusion-related AE is headache. More serious reactions, including true anaphylaxis and anaphylactoid reactions, occur less frequently. Most reactions are related to the rate of infusion and can be prevented or treated just by slowing the infusion rate. Medications such as nonsteroidal anti-inflammatory drugs, antihistamines, or corticosteroids also may be helpful in preventing or treating these common AEs. IgA deficiency with the potential of IgG or IgE antibodies against IgA increases the risk of some AEs but should not be viewed as a contraindication if IgG therapy is needed. Potentially serious AEs include renal dysfunction and/or failure, thromboembolic events, and acute hemolysis. These...

To determine the cost of the dialytic management of paediatric acute kidney injury in a low-income country. All children under the age of 15 years, who had either peritoneal dialysis or haemodialysis for acute kidney injury in Aminu Kano Teaching Hospital over a 1-year period, were studied. The average cost of each dialysis modality was estimated. Of 20 children, who had dialysis for acute kidney injury, 12 (60%) had haemodialysis and 8 (40%) had peritoneal dialysis. The mean cost for haemodialysis exceeded that of peritoneal dialysis ($363.33 vs. $311.66, t = 1.04, P = 0.313) with the mean cost of consumables significantly accounting for most of the cost variation ($248.49 vs. $164.73, t = 2.91, P = 0.009). Mean costs of nephrologist visit and nursing were not found to be significant. Peritoneal dialysis is the less costly alternative for managing acute kidney injury in children in our environment.

The combined use of acetaminophen with ibuprofen has long been in clinical use because the target of action of each drug is different and they do not interfere with each other. Appropriate dosing and managing of these drugs do not likely lead to organ toxicity. However, both acetaminophen and ibuprofen can induce liver problems and acute kidney failure, respectively, if administered at high doses. We report the case of a female child, in treatment with both acetaminophen and ibuprofen, administered at therapeutic antipyretic doses in condition of volume depletion, who suffered acute kidney and liver failure. The combined ibuprofen and acetaminophen treatment, even if administered at therapeutic dosages and in a reduced number of doses, may be dangerous in conditions of volume depletion.

Acute kidney injury (AKI) is associated with significantly increased morbidity and mortality. To provide a uniformly accepted definition, the RIFLE classification was introduced by the Acute Dialysis Quality Initiative, recently modified by the Acute Kidney Injury Network (AKIN), suggesting staging of AKI based on dynamic changes within 48 h. This study compares these two classification systems with regard to outcome. Cohort analysis of SAPS 3 database. Sixteen thousand seven hundred and eighty-four ICU patients from 303 ICUs were analysed. Classification was performed according to RIFLE (Risk, Injury, Failure) or according to AKIN (stage 1, 2, 3) without including a requirement of renal replacement therapy in the analysis. Changes of serum creatinine as well as urinary output were assessed for both AKIN and RIFLE during the first 48 h of ICU admission. Primary endpoint was hospital mortality. Incidence of AKI in our population of critically ill patients was found to range between 28.5 and 35.5% when applying AKIN and RIFLE criteria, respectively, associated with increased hospital mortality averaging 36.4%. Observed-to-expected mortality ratios revealed excess mortality conferred by any degree of AKI increasing from 0.81 for patients classified as non-AKI up to 1.31 and 1.23 with AKIN stage 3 or RIFLE Failure, respectively. AKIN misclassified 1,504 patients as non-AKI compared to RIFLE which misclassified 504 patients. Acute kidney injury classified by either RIFLE or AKIN is associated with increased hospital mortality. Despite presumed increased sensitivity by the AKIN classification, RIFLE shows better robustness and a higher detection rate of AKI during the first 48 h of ICU admission.

Acute kidney injury (AKI) morbidity and mortality rates remain high. Variable AKI outcomes have been reported in association with aminophylline treatment. This study evaluated AKI outcome in a group of Nigerian children treated with aminophylline. This is a retrospective study of AKI in children treated with (N=9) and without (N=8) aminophylline. Studied outcome indices comprised urine flow rate (UFR), duration of oliguria/anuria, progression through AKI stages, number of patients requiring dialysis and mortality. Mean ages for the control and aminophylline arms were 4.6±2.7 and 4.9±2.1 years (P=0.7), respectively. All patients progressed to stage-3 AKI. Baseline median UFRs in the aminophylline and control arms were similar (0.13 Vs 0.04 ml/kg/hour respectively, P=0.5). The median UFR was significantly higher on day-5 (0.8 Vs 0.1; P=0.03), day-6 (1.0 Vs 0.2; P=0.02), and day-7 (1.2 Vs 0.2; P=0.03) in the aminophylline than the control arm, respectively. Short duration of oliguria/a...

Despite the high costs of treatment of people with kidney disease and associated comorbid conditions, the amount of reliable information available to guide the care of such patients is very limited. Some treatments have been assessed in randomized trials, but most such trials have been too small to detect treatment effects of a magnitude that would be realistic to achieve with a single intervention. Therefore, KDIGO convened an international, multidisciplinary controversies conference titled " Challenges in the Conduct of Clinical Trials in Nephrology " to identify the key barriers to conducting trials in patients with kidney disease. The conference began with plenary talks focusing on the key areas of discussion that included appropriate trial design (covering identification and evaluation of kidney and nonkidney disease outcomes) and sensible trial execution (with particular emphasis on streamlining both design and conduct). Break out group discussions followed in which ...

We report the cases of two patients who developed acute renal failure following multiple wasp stings. Both patients required dialysis and recovered within 4 weeks. The kidney biopsy from one patient showed acute tubular necrosis with interstitial nephritis. One patient had complete recovery of renal function on follow-up, while the other was lost to follow-up.
