Objective: To investigate asphyxiated neonates for acute kidney injury, compare the occurrence between preterms and terms and to correlate the severity and type of renal injury with the degree of asphyxia and hypoxic ischemic encephalopathy (HIE) grading. Materials and Methods: Renal functions were assessed using urine output and biochemical parameters such as blood urea, serum creatinine, serum sodium, potassium, and calcium. These were evaluated on alternate days till day 7 or recovery or death. Results: Total 108 asphyxiated neonates were enrolled: 63 term and 45 preterm. A total of 28 (25.9%) developed acute kidney injury: 9 (32.1%) had oliguric acute renal injury and the rest 19 (67.8%) had nonoliguric acute renal injury. A total of 77.7% neonates had a prerenal cause and the other 22.2% had an intrinsic cause for the kidney injury. Levels of blood urea and serum creatinine were maximally elevated on day 5 of life. Biochemical derangements correlated well with the Apgar score at birth and severity of HIE. No statistically significant difference was observed in the incidence of renal injury between preterm and term asphyxiated neonates. Conclusion: Perinatal asphyxia is an important cause of renal injury in neonates. A majority of neonates had nonoliguric and pre renal type of acute kidney injury. The more severe the degree of asphyxia, the more prone they were to develop renal complications.

Background: Acute kidney injury (AKI) is a common consequence of perinatal asphyxia, occurring in upto 56% of these neonates. It is important to recognize AKI in asphyxiated neonates to facilitate administration of appropriate fluids and electrolytes in order to improve their outcome. Objectives: To determine the incidence of AKI in asphyxiated neonates and to correlate the severity and type of AKI with Apgar score and severity of hypoxic ischemic encephalopathy (HIE). Methods: 75 neonates were enrolled – 50 asphyxiated and 25 healthy neonates. Renal functions were assessed using urine output, urine microscopy, biochemical parameters and sonography. The values obtained were correlated with the severity of HIE. Neonates with AKI were managed as per unit protocol. Results: Of the 50 asphyxiated neonates, 32 (64%) had AKI: 25 (78.12 %) neonates with pre-renal AKI and the remaining 7 (21.88 %) with intrinsic AKI. Out of the 32 asphyxiated neonates with AKI, 12 (37.5%) had oliguric AKI, while the remaining 20 (62.5%) had non-oliguric AKI. Levels of blood urea and serum creatinine were significantly higher in asphyxiated neonates as compared to healthy controls (p 0.001). Biochemical derangements correlated well with the severity of HIE and Apgar scores. Serum sodium and creatinine clearance showed significantly different values in asphyxiated babies compared to controls. There was no significant difference in the urine ouput in the control and study group. Sonographic abnormalities were seen most often in oliguric babies, and indicated bad prognosis. Mortality was higher in babies with oliguric AKI. Conclusions: Perinatal asphyxia is an important cause of neonatal AKI. Majority of the babies had non-oliguric AKI and responded well to fluid challenge. Abnormalities in the renal function correlates well with the severity of HIE. Intrinsic AKI, oliguria, hyponatremia, reduced creatinine clearance and abnormal sonographic scan suggest bad prognosis in neonatal AKI secondary to perinatal asphyxia.

Background and objectives: Uremic encephalopathy is the most important complication of renal failure and urgent dialysis treatment is required. Parathormone (PTH) contributes to the etiopathogenesis of uremic encephalopathy. PTH is a hormone that acts in the calcium balance in the organism. The aim of our study was to investigate the effect of serum adjusted and ionized calcium on the development of uremic encephalopathy in patients with acute renal injury (acute kidney injury network (AKIN) stage 3). Materials and Methods: Our study was supported by Canakkale Onsekiz Mart University Scientific Research Projects Unit (ID:1278). Three groups were formed for the study. The first group was acute renal failure AKIN stage 3 (N: 23), the second group was AKIN stage 3, and the patients who had emergency hemodialysis (N: 17) and the third group (N: 9) had AKIN stage 3 hemodialysis due to uremic encephalopathy. In these patient groups, 25-hydroxy vitamin D, PTH, calcium, albumin, urea, creatinine, and blood-gas-ionized calcium were observed in their serum during the first application. Calcium, albumin, urea, creatinine, and ionized calcium in blood gas were also examined in serum at 24th and 72th hours. Data were analyzed using SPSS version 19.0. Kruskal–Wallis test and Mann–Whitney U test were applied for the variables that did not comply with normal distribution. p < 0.005 was accepted statistically. Results: A statistically significant difference was found between the measurement creatinine values at the 24th and 72th hours of admission in AKIN stage 3 patients who applied to the emergency department (p = 0.008). A statistically significant difference was found in the measured calcium values (p = 0.013). A statistically significant difference was found in the measured ionized calcium values (p = 0.035). Conclusions: In our study, the effect of ionized calcium level on uremic encephalopathy in serum creatinine, calcium, and blood gas in patients presenting with acute renal injury, AKIN stage 3, was significant, but studies with new and large groups are needed.

Background: As a result of prematurity, Acute kidney injury (AKI) occurs commonly in preterm neonates and is associated with increased morbidity and mortality. (AKI) is defined as a rapid, potentially reversible deterioration in renal functions sufficient to result in accumulation of nitrogenous wastes in the body. Aim of the Study: the aim of this study was to determine whether preterm neonates who took caffeine citrate from the first day after birth were less likely to AKI within the first 7 days. Patients and Methods: This case control study was conducted on 100 preterm neonates at Neonatal Intensive Care Units (NICUS), Pediatric Department, Tanta University with gestational age less than (30 weeks) were grouped into group A and B. Group A 50 preterm neonates who received caffeine citrate from the first day after birth with dose (20 mg/kg) loading dose, and (5 mg/kg/dose) every 24hrs of maintenance dose, given as slow intravenous infusion over twenty to thirty minutes for a week. Group B 50 preterm neonates who did not receive caffeine citrate. Inclusion Criteria: all preterms <30 weeks admitted within first 24 hours after birth presented by respiratory distress according to Downes score. Exclusion Criteria: newborns with congenital heart disease except non-significant PDA, neonatal mortality < 48 h of life, clinical signs suggest chromosomal anomalies, newborns with congenital renal anomalies. Hematological Investigations: serum albumin, serum creatinine, blood urea. Urinary Investigations: measuring urine output. Results: There was a statistically significant difference between the two studied groups as regard serum creatinine in day (5,7) (p<0.001), urea in day 7 (p value <0.001), serum albumin in day (5,7) (p value ≤ 0.05), urine output in day (4,5,6,7) (p value ≤0.05), AKI incidence (p value <0.001). Conclusion: Caffeine Citrate administration in preterm neonates from the first day of life for one week was associated with reduced occurrence and severity of AKI.

AbstractObjectives:This study was designed to find the reliability of serum NGAL as an early and better diagnostic biomarker than that of serum creatinine for acute kidney injury after percutaneous coronary intervention in Pakistani population.Materials and methods:One hundred and fifty-one patients undergoing elective percutaneous coronary intervention were included and demographic data were recorded. Blood was drawn by venipuncture in clot activator vacutainers and serum was separated and stored at 4°C. Sample was drawn before the percutaneous procedure and subsequently sampling was done serially for 5 days.Results:The mean±SD serum NGAL pre-PCI (39.92± 10.35 μg/L) and 4 h post-PCI (100.42±26.07 μg/L) showed highly significant difference (p<0.001). The mean±SD serum creatinine pre-PCI (70.1±11.8 μmol/L) and post-PCI (71.2±11.6 μmol/L) showed significant difference (p=0.005) on day 2 onwards but mean microalbumin showed insignificant results (p=0.533). The serum NGAL predicted CI-AKI with sensitivity of 95.8% and specificity of 97.6% for a cut off value of 118 μg/L.Conclusion:Our results suggest that NGAL is an excellent early diagnostic biomarker for acute kidney injury in patients undergoing elective percutaneous coronary intervention.

Background The causative virus of coronavirus disease 2019 (COVID-19) may cause severe fatal pneumonia. The clinical presentation includes asymptomatic infection, severe pneumonia, and acute respiratory failure. Data pertaining to acute renal injury due to COVID-19 in patients who have undergone renal transplantation are scarce. We herein report two cases of COVID-19 along with acute kidney injury following kidney transplantation. Case presentation: Two patients with COVID-19 underwent renal transplantation and were subsequently diagnosed with acute kidney injury. The first patient presented with progressive respiratory symptoms and acute renal injury. He was treated with diuretics and suspension of immunosuppressive therapy; however, the patient died. The second patient presented with respiratory tract symptoms, hypoxemia, and progressive deterioration of renal function followed by improvement. Her mycophenolate mofetil was stopped after admission, and tacrolimus was discontinued 10 days later. Moxifloxacin and methylprednisolone were continued in combination with albumin and gamma globulin infusion. A diuretic was administered, and prednisone was gradually reduced along with tacrolimus. The patient exhibited a satisfactory clinical recovery. Conclusion Patients who develop COVID-19 after kidney transplantation are at risk of acute kidney injury, and their prednisone, immunosuppressant, and gamma globulin treatment must be adjusted according to their condition.

Acute kidney injury (AKI) is a common and frequently fatal illness in critically ill patients. The reliance on daily measurements of serum creatinine as a surrogate of glomerular filtration rate (GFR) not only delays diagnosis and development of successful therapies but also hinders insight into the pathophysiology of human AKI. Measurement of GFR under non-steady-state conditions remains an elusive gold standard against which biomarkers of renal injury need to be judged. Approaches to the rapid (near real-time) measurement of GFR are explored. Even if real-time GFR was available, absent baseline information will always limit diagnosis of AKI based on GFR or serum creatinine to a detection of change. Biomarkers of renal cellular injury have provided new strategies to facilitate detection and early intervention in AKI. However, the diagnostic and predictive performance of urinary biomarkers of injury vary, depending on both the time after renal injury and on the preinjury GFR. Progress in understanding the role of each novel biomarker in the causal pathways of AKI promises to enhance their diagnostic potential. We predict that combining rapid measures of GFR with biomarkers of renal injury will yield substantive progress in the treatment of AKI.

Abstract. Background: Neutrophil gelatinase-associated lipocalin (NGAL) has been described as a potential biomarker of acute kidney injury (AKI) in different settings, but its behaviour under influence of open and endovascular repair of thoraco-abdominal aortic aneurysms (TAAA) has not been assessed yet. In this study, the course of NGAL was observed and differences of serum- (sNGAL) and urine-NGAL (uNGAL) levels following TAAA repair, especially with regard to AKI, were evaluated. Patients and methods: In this retrospective single centre study, 52 patients (mean age 64.5 years, [43–85 years]), including 39 (75 %) men, were enrolled (2014–2015, 13.2 months mean follow-up). Levels of sNGAL and uNGAL were measured perioperatively for 48 hours on intensive care unit. Twenty-three patients were treated by endovascular and 29 by open TAAA-repair. Results: Logistic regression revealed an increase in NGAL (sNGAL p = 0.0263, uNGAL p = 0.0080) corresponding with an increase in serum creatinine within the first 48 hours. Fourteen patients (26.9 %) developed AKI and 11 (21.1 %) required dialysis. The course of NGAL differed significantly (uNGAL p < .0001, sNGAL p = 0.0002) between patients suffering from AKI requiring dialysis and patients without AKI. The predictive power of uNGAL was three times higher than that of sNGAL (estimate of the regression slope 0.1382 vs. 0.0460). No significant difference between patients undergoing open or endovascular TAAA repair regarding the perioperative course of sNGAL and uNGAL was observed. Conclusion: serum-NGAL and urine-NGAL correlate with serum creatinine levels and AKI requiring dialysis. Furthermore, the postoperative course of sNGAL and uNGAL after open and endovascular TAAA repair is not significantly different. Taken together, the results indicate that uNGAL and, to a lesser extent, sNGAL could be considered biomarkers for early detection of perioperative AKI after open and endovascular TAAA surgery.

Background: Even minor postoperative reductions in renal function influence the outcome of cardiac surgery. The mechanisms of postoperative renal injury in cardiac surgery are multifactorial and include ischemia-reperfusion injury. The study investigates the effect of the antioxidant ascorbic acid on the postoperative acute kidney injury after elective CABG surgery.Methods: A prospective randomized single-center trial was conducted in on-pump coronary artery bypass patients. The patients in the ascorbic acid group received 2 grams of ascorbic acid 24 hours and 2 hours preoperatively and 1 gram twice daily five days after the surgery.  Postoperatively, the subjects were monitored for renal dysfunction and other complications.Results: 100 patients were included, with 50 patients in each study group. The groups were well matched for baseline demographics, preoperative medications, comorbidities, and had similar intraoperative characteristics. The incidence of postoperative acute kidney injury in the ascorbic acid group was 16% and 14% in the control group (P = .779). The groups also did not differ in peak postoperative serum creatinine (83 [33] µmol/L versus 83 [39] µmol/L; P = .434), the lowest postoperative creatinine clearance (96.40 ± 35.78 mL/min versus 90.89 ± 36.18 mL/min; P = .766), and time from surgery to the onset of peak postoperative serum creatinine (1.64 ± 1.34 days versus 1.92 ± 1.54 days; P = .393). There was no dialysis required in any patient. Conclusion: The results of this study did not demonstrate a significant protective effect of ascorbic acid on the incidence of postoperative acute renal injury in elective on-pump CABG patients.

Currently, due to the dynamic development of surgical technologies, indications for organ-sparing treatment of kidney cancer are expanding. Acute kidney injury is a serious complication that leads to chronic kidney disease, increased postoperative mortality, deterioration of long-term functional outcomes, and increased hospitalization. At present, it is known that even a slight damage to kidneys or their impairment, presented by a decreased urine output and change in blood biochemical parameters, entails serious clinical consequences and is associated with a poor prognosis. Damaging factors, when the kidney is exposed, initially induce molecular changes, which entail the production of certain biomarkers, and only after that clinical aspects of kidney damage develop. The causes of acute kidney injury can be different, from specific renal disorders (acute interstitial nephritis, vascular and glomerular lesions, prerenal azotemia, obstructive disorders) to toxic damages, direct trauma and surgical treatment. The development of acute renal injury in the postoperative period is a serious complication of the surgical treatment of kidney disease, and, according to various authors, the frequency of its occurrence varies from 5.5 % to 34 %. An active study of this problem made it possible to find specific biomarkers that give the possibility to predict and diagnose acute renal injury in the early stages, to optimize the treatment strategy, to reduce the incidence of postoperative complications, and to shorten the period of postoperative rehabilitation. Currently, the most studied of acute kidney injury (AKI) biomarkers are cystatin C, neutrophil gelatinase-associated lipocalin‑2 (NGAL), hepatic protein L-FABP, KIM‑1 (Kidney injury molecule‑1), Interleukin – 18. Further study of AKI biomarkers will make it possible to determine the most significant ones for subsequent use in everyday practice
