OBJECTIVETo analyze the perioperative clinical data of children with congenital heart disease complicated by acute kidney injury (AKI) after cardiopulmonary bypass (CPB) surgery, and to explore potential factors influencing the prognosis.
METHODSA retrospective analysis was performed among 118 children with congenital heart disease who developed AKI within 48 hours after CPB surgery.
RESULTSIn the 118 patients, 18 died after 48 hours of surgery. Compared with the survivors, the dead children had significantly higher incidence of cyanotic disease and Risk Adjustment for Congenital Heart Surgery-1 (RACHS-1) scores before surgery; during surgery, the dead children had significantly longer CPB time and aortic cross-clamping time, a significantly higher proportion of patients receiving crystalloid solution for myocardial protection, and a significantly higher mean blood glucose level. Within 48 hours after surgery, the dead children had significantly higher positive inotropic drug scores, significantly higher creatinine values, a significantly higher incidence of stage 3 AKI, a significantly higher proportion of patients receiving renal replacement the, and significantly higher usage of blood products (P<0.05). The mortality rate of the patients increased with increased intraoperative blood glucose levels (P<0.05). Patients with intraoperative blood glucose levels >8.3 mmol/L had a significantly lower postoperative cumulative survival rate and a significantly shorter mean survival time than those with blood glucose levels ≤ 8.3 mmol/L (P<0.05).
CONCLUSIONSIntraoperative blood glucose levels are associated with the prognosis in children with congenital heart disease complicated by AKI after CPB surgery. Maintaining good intraoperative blood glucose control can improve the prognosis of the children.

PURPOSE: Contrast-induced acute kidney injury (CI-AKI) is associated with poor outcomes after percutaneous coronary intervention. However, CI-AKI has rarely been evaluated within the neurovascular field. The aim of this study was to investigate the incidence and clinical implication of CI-AKI after coil embolization in patients with an aneurysmal subarachnoid hemorrhage (aSAH). MATERIALS AND METHODS: Between January 2005 and March 2016, 192 patients who underwent coil embolization were enrolled in this study. CI-AKI was defined as an increase from baseline serum creatinine concentration of >25% or >0.5 mg/dL within 72 hours after coil embolization. A poor clinical outcome was defined as a score of ≥3 on the modified Rankin Scale at one-year post-treatment. RESULTS: A total of 16 patients (8.3%) died as a result of medical problems within one year. CI-AKI was identified in 14 patients (7.3%). Prominent risk factors for one-year mortality included CI-AKI [odds ratio (OR): 16.856; 95% confidence interval (CI): 3.437–82.664] and an initial Glasgow Coma Scale (GCS) score ≤8 (OR: 5.565; 95% CI: 1.703–18.184). A poor clinical outcome was associated with old age (≥65 years) (OR: 7.921; 95% CI: 2.977–21.076), CI-AKI (OR: 11.281; 95% CI: 2.138–59.525), an initial GCS score ≤8 (OR 31.02; 95% CI, 10.669–90.187), and a ruptured aneurysm (p=0.016, OR: 4.278) in posterior circulation. CONCLUSION: CI-AKI seems to be an independent predictor of the overall outcomes of aSAH after endovascular treatment.

3.Acute liver failure in Korea: etiology, prognosis and treatment.
The Korean Journal of Hepatology 2010;16(1):5-18
Acute liver failure (ALF) is a rare condition in which rapid deterioration of liver function results in altered mentation and coagulopathy in individuals without previously recognized liver disease. The outcomes of patients with ALF vary greatly according to etiology, and the etiology of ALF varies markedly by geographical region. In Korea, about 90% of ALF are associated with etiologies that usually result in poor outcomes, including hepatitis B virus (HBV) infection and herbal remedies. The main causes of death in patients with ALF are increased intracranial pressure, systemic infection, and multi-organ failure. Recent advances in the intensive care of patients with ALF have contributed to a marked improvement in their overall survival. Emergency adult to adult living-donor liver transplantation (LDLT) can be performed expeditiously and safely for patients with ALF, and greatly improves survival rate as well as deceased-donor transplantation. As the window during which transplantation is possible is limited, emergency adult LDLT should be considered to be one of the first-line treatment options in patients with ALF, especially in regions in which ALFs are caused by etiologies associated with poor outcome and the supply of organs is very limited.

Some cases of Middle East Respiratory Syndrome-Coronavirus (MERS-CoV) infection presented renal function impairment after the first MERS-CoV patient died of progressive respiratory and renal failure. Thus, MERS-CoV may include kidney tropism. However, reports about the natural courses of MERS-CoV infection in terms of renal complications are scarce. We examined 30 MERS-CoV patients admitted to National Medical Center, Korea. We conducted a retrospective analysis of the serum creatinine (SCr), estimated glomerular filtration rate (eGFR), urine dipstick tests, urinary protein quantitation (ACR or PCR), and other clinical parameters in all patients. Two consecutive results of more than trace (or 1+) of albumin and blood on dipstick test occurred in 18 (60%) (12 [40%]) and 22 (73.3%) (19 [63.3%]) patients, respectively. Fifteen (50.0%) patients showed a random urine ACR or PCR more than 100 mg/g Cr. Eight (26.7%) patients showed acute kidney injury (AKI), and the mean and median durations to the occurrence of AKI from symptom onset were 18 and 16 days, respectively. Old age was associated with a higher occurrence of AKI in the univariate analysis (HR [95% CI]: 1.069 [1.013-1.128], P = 0.016) and remained a significant predictor of the occurrence of AKI after adjustment for comorbidities and the application of a mechanical ventilator. Diabetes, AKI, and the application of a continuous renal replacement therapy (CRRT) were risk factors for mortality in the univariate analysis (HR [95% CI]: diabetes; 10.133 [1.692-60.697], AKI; 12.744 [1.418-114.565], CRRT; 10.254 [1.626-64.666], respectively). Here, we report renal complications and their prognosis in 30 Korean patients with MERS-CoV.

OBJECTIVETo analyze the preoperative risk factors on liver transplant recipients with acute renal failure(ARF), and to evaluate renal replacement therapy (RRT) as a transitonary therapy before liver transplantation.
METHODSLiver transplant recipients with acute renal failure treated with renal replacement therapy between January 1st, 2001 and January 1st, 2008 in our center were retrospected. Clinical characteristics, the kinds of RRT and prognosis were analyzed; Logistic regression was applied to analyze the parameters that can forecast the motality of the liver transplant recipients with acute renal failure.
RESULTSOf the patients who received RRT, 30% survived to liver transplantation, 67.5% died while waiting for liver transplantation. The dead had a higher multiple organ dysfunction score (MODS), and lower mean arterial pressure than those survived to liver transplantation. There was no significant difference in the duration of RRT between continuous renal replacement therapy (CRRT) patients and hemodialysis patients. CRRT patients had a higher MODS, lower mean arterial pressure, lower serum creatinine than hemodialysis patients. Lower mean arterial pressure was statistically associated with higher risk of mortality.
CONCLUSIONThough mortality was high, RRT helps part (30%) of patients survive to liver transplantation. Therefore, considering the high mortality without transplantation, RRT is acceptable for liver transplant recipients with ARF.

BACKGROUND/AIMS: New definitions of acute kidney injury (AKI) have recently emerged. Some studies have suggested that duration of AKI is an additional predictive parameter for mortality. Here, we evaluated whether AKI duration was predictive of long-term mortality in patients with hospital-acquired acute kidney injury (HAAKI). METHODS: We prospectively enrolled patients who developed HAAKI at an urban university hospital, from September 2007 to August 2008 and followed them until December 2011. Patients were divided into two groups by duration of the AKI (1 to 5 days vs. > or = 6 days), and long-term mortality was compared. RESULTS: HAAKI developed in 1.2% of patients during the enrollment period. The median follow-up period was 240 days (interquartile range, 53 to 1,428). In 42.3% of patients (n = 52), the AKI lasted 1 to 5 days, while it lasted > or = 6 days in 57.7% (n = 71). Survival analysis showed that a longer duration of AKI increased the risk of death. Long-term survival was significantly different in the two groups. CONCLUSIONS: The duration of AKI influenced mortality rates in hospitalized patients. Thus, AKI duration is a parameter affecting mortality in HAAKI.

OBJECTIVETo investigate the efficacy of continuous blood purification (CBP) and to explore its mechanism in the treatment of pediatric septic shock.
METHODSNine children weighted 3.1 kg - 14.0 kg with septic shock were treated with continuous veno-venous hemofiltration (CVVH) which is also referred to as CBP with blood access of double-lumen hemodialysis catheter of 6.5 to 8Fr inserted via central vein, hemofilters of Minifilter plus (for children with body weight < 5 kg) or AV400s (for children with body weight > or = 5 kg), child's type extracorporeal circuit vessel and heparin anticoagulation. The replacement solution was delivered pre-dilution after 3 to 4 hours' post-dilution. The blood gas, clinical biochemical items, medium molecule substance (MMS) concentration in blood as well as capillary refill time (CRT), BP, urine output, vasopressors dosage were examined at a set of time points from the beginning to the end of the CVVH.
RESULTSOf the 9 children, 6 had acute renal failure (ARF), 3 had acute respiratory distress syndrome (ARDS), 5 were blood culture positive and all the 9 needed vasopressors to keep BP before CVVH. The blood pH was 7.14 +/- 0.23, base excess (BE) was -11.3 +/- 4.25 mmol/L, MMS was 3532 +/- 519 U/L, PO2/FiO2 was 188 +/- 33, CRT > 5 s, urine output was 0.85 +/- 0.52 ml/(kg.hr) and the adrenalin dosage 1.36 +/- 0.48 microg/(kg.min), and dopamine 16.35 +/- 3.27 microg/(kg.min) before CVVH. The patients' condition was improved much as demonstrated by pH 7.38 +/- 0.16, BE -0.28 +/- 1.37 mmol/L, MMS 2576 +/- 375 U/L, PO2/FiO2 285 +/- 63, CRT < 2 s, and the adrenalin dosage 0.08 +/- 0.04 microg/(kg.min) and dopamine 8.53 +/- 6.72 microg/(kg.min), urine output 2.9 +/- 1.6 ml/(kg.hr) after 24 hour treatment with CVVH. Of the 9 children, 2 died of MODS (1 intussusception complicated with intestine necrosis, 1 severe scald) and 1 was given up because of severe intestinal fistula, the other 6 children recovered at the end.
CONCLUSIONCBP was effective in treatment of pediatric septic shock by improving the oxygenation, correcting metabolic acidosis, stabilizing BP, increasing the tissue perfusion and eliminating the medium molecule substances.
