BACKGROUND: The aim of this study was to investigate the incidence and clinical characteristics of intravenous (IV) or inhaled (IH) colistin-associated acute kidney injury (AKI) using the Risk, Injury, Failure, Loss, End-stage Renal Disease criteria. METHODS: From 2010 to 2014, 160 patients were treated with IV or IH colistin. Of these, we included 126 patients who received colistin for > 72 hours for the treatment of pneumonia and compared the incidence and clinical characteristics of patients in the IV (n = 107) and IH (n = 19) groups. RESULTS: The patients included 104 men and 22 women, with a mean age of 69 years (range, 24–91 years). The mortality rate was 45%, and AKI occurred in 75 (60%) patients. At the end of therapy, the bacteriologic cure rate was 66%. There were no differences in the clinical characteristics between the IV and IH groups except for age. In comparison with patients in the IV group, the patients in the IH group were older (74 ± 8 vs. 68 ± 12 years, P = 0.026). The incidence of AKI was not different between the 2 groups (62 vs. 47%, P = not significant), and there was no difference in the severity of AKI according to the Risk, Injury, Failure, Loss, End-stage Renal Disease criteria. Of the 83 patients with AKI, 6 and 1 patients underwent renal replacement therapy, respectively. CONCLUSION: The incidence of AKI in patients with colistin therapy is 60% in our center. It seems that IH colistin therapy could not be better in safety than IV colistin therapy.

BACKGROUND: Although acute renal failure (ARF) after coronary artery bypass graft (CABG) is relatively rare, but devastating complication with high mortality. Our study aims to evaluate the effectiveness of early application of CRRT in patients with ARF which developed after on-pump CABG. MATERIAL AND METHOD: Two hundred and eighty seven patients underwent isolated on-pump CABG between May 2002 and Feb. 2006 at our institution, of whom 15 (5.2%) needed CRRT (11 patients for postoperatively developed ARF and the remaining 4 patients with pre- existing dialysis-dependent chronic renal failure (CRF) for postoperative hemodynamic and metabolic control). Criteria for early application of CRRT were as follows; decreased urine output less than 0.5 cc/h/kg for 2 consecutive hours and elevated serum creatinine level greater than 2.0 mg/dL. RESULT: The incidence of ARF requiring CRRT after on-pump CABG was 3.9% (11/283) and the overall hospital mortality of patient with CRRT was 33.3% (5/15). Of 5 deaths, 4 were patients with postoperatively developed ARF, and 1 was a patient with pre-existing dialysis- dependent CRF patient. The mean time between the operation and the initiation of CRRT was 25.8+/-5.8 hours and the mean duration of CRRT was 62.1+/-41.2 hours. Of the 7 survivors who were not on dialysis-dependent preoperatively, 6 patients fully recovered renal function during hospital stay and 1 patient required permanent renal supportive treatment after discharge from hospital. CONCLUSION: Early application of CRRT could maintain stable postoperative hemodynamic status and make outcomes better than those of previous reports in patients with ARF which developed after on-pump CABG.

BACKGROUND/AIMS: Continuous renal replacement therapy (CRRT) has been widely used for treating critically ill patients with acute kidney injury (AKI). Whether CRRT is better than intermittent hemodialysis for the treatment of AKI remains controversial. We sought to identify the clinical features that can predict survival for the patients who are treated with CRRT. METHODS: We analyzed the data of 125 patients who received CRRT between 2005 and 2007. We identified the demographic variables, the underlying diagnoses, the duration of CRRT, the mean arterial blood pressure (ABP) and the Simplified Acute Physiology Score (SAPS) II. The classification/staging system for acute kidney injury (AKI) was applied to all the patients, who were then divided into stage 1-3 subgroups. RESULTS: The average age of the patients was 61.414.3 years and the mortality rate was 60% (75 of 125 patients). The survivors had a significantly higher mean ABP and a higher mean serum bicarbonate level, which were measured the day after CRRT, than the nonsurvivors (86.723.7 vs. 69.224.6 mm Hg, respectively, 21.43.5 vs. 16.45.4 mmol/L, respectively,; p<0.05 for each). The stage 3 AKI patients showed the worst parameters for the SAPS II score and the serum levels of creatinine and blood urea nitrogen. The mortality rate was higher for the stage 3 subgroup than the other groups (70.5%, p<0.05). CONCLUSIONS: The patients with AKI and who require CRRT continue to have a high mortality rate. A higher mean ABP and a higher serum bicarbonate level measured the day after CRRT may predict a more favorable prognosis. The staging system for AKI can improve the ability to predict the outcomes of CRRT patients.

BACKGROUND:Immunosuppressive therapy after renal transplantation stimulates the replication of hepatitis B virus (HBV) and may lead to increased liver-related mortality. We investigated the effectiveness of lamivudine for the treatment of HBV reactivation in renal transplant recipients. METHODS:We reviewed the clinical course of 16 HBsAg-positive renal transplant patients (M:F=13:3) treated with lamivudine for chronic hepatitis B. The outcome of prophylactic (HBV-DNA negative, n=5) and preemptive (HBV-DNA positive, n=4) therapy without hepatic dysfunction was analyzed in compared with that of salvage (n=7) therapy for post-transplantation hepatic dysfunction. RESULTS:Chronic hepatitis developed in four (25 %) of the enrolled 16 recipients, including one fulminant hepatic failure in prophylactic group and one hepatocellular carcinoma in the salvage group. We found that three (33%) of 9 patients under prophylactic and preemptive therapy showed post-transplantation hepatic dysfunction, but that only one (14%) of 7 patients showed elevated liver enzyme after salvage therapy. During a mean follow-up, under prophylactic and preemptive therapy, of 38 months, five (56%) of 9 patients showed resistance to lamivudine. In seven patients under salvage therapy for a mean follow-up of 26 months, only one patient (14%) showed resistance. At the last follow-up, liver enzyme levels were normal in 14 patients (87.5%). CONCLUSION:It may be beneficial to use lamivudine for the prevention of liver-related mortality in renal transplant recipients with HBs-Ag positivity. Prophylactic and preemptive lamivudine therapy tend to show higher viral resistance compared with salvage therapy.

5.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.

PURPOSE: Continuous renal replacement therapy (CRRT) has been established for critically ill acute kidney injury (AKI) patients. In addition, some centers consist of a specialized CRRT team (SCT) with physicians and nurses. To our best knowledge, however, ona a few studies have yet been carried out on the superiority of SCT management. MATERIALS AND METHODS: A total of 551 patients, who received CRRT between January 2008 and March 2009, were divided into two groups based on the controller of CRRT. The impact of the CRRT management on 28-day mortality was compared between two groups by Kaplan-Meier curve and Cox analysis. RESULTS: During the study period, the number of filters used, down-time per day, and intensive care unit length of day were significantly higher in non-SCT group than in SCT group (6.2 hrs vs. 5.0 hrs, p=0.042; 5.0 hrs vs. 3.8 hrs, p<0.001; 27.5 days vs. 21.1 days, p=0.027, respectively), while net ultrafiltration rate was significantly lower in non-SCT group than SCT group (28.0 mL/kg/hr vs. 29.5 mL/kg/hr, p=0.043, respectively). In addition, 28-day mortality rate was significantly lower in SCT group than with non-SCT group (p=0.031). Moreover, Cox regression analysis showed that 28-day mortality rate was significantly lower in SCT control group, even after adjusting for age, gender, severity scores, biomarkers, risk, injury, failure, loss, and end-stage renal disease, and contributing factors (hazard ratio 0.91, p=0.046). CONCLUSION: A well-trained CRRT team could be beneficial for mortality improvement of AKI patients requiring CRRT.

BACKGROUND/AIMS: Transcatheter arterial chemoembolization (TACE) is a major modality in the treatment of unresectable hepatocellular carcinoma. Acute renal failure (ARF) may occur after TACE because of underlying liver cirrhosis and the presence of radiocontrast agent. However, the data available regarding this complication are variable and limited. The aim of this study was to determine the incidence and associated risk factors of ARF after TACE. METHODS: From January 2001 to December 2004, a total of 632 procedures were performed in 377 patients. Of these, the cases with high creatinine levels (> or = 2 mg/dL) before TACE and with incomplete medical records were excluded, which resulted in 463 procedures in 319 patients (256 males and 63 females; age 58.7+/-9.9 years, mean+/-SD) being examined for this study. Various clinical and radiological data before and after the procedure were reviewed retrospectively. RESULTS: ARF occurred following 15 (3.2%) of the 463 procedures within 7 days of TACE. Univariate analysis revealed that serum albumin levels (P=0.025), Model for End-Stage Liver Disease score (P=0.001), the distribution of Child-Pugh class (P=0.027), and the proportions of patients with ascites (P<0.001), using diuretics (P=0.010), and with a serum creatinine level > or = 1.5 mg/dL (P=0.023) differed significantly between patients with or without ARF after TACE. In multivariate analysis, the presence of ascites (P=0.005; odds ratio, 5.297) and serum creatinine level > or = 1.5 mg/dL (P=0.007; odds ratio, 7.358) were independently associated with the development of ARF. CONCLUSIONS: The incidence of ARF after TACE was 3.2%, and the presence of ascites and an abnormal baseline serum creatinine level were the risk factors for ARF.
