BACKGROUND: Clinical studies suggest that postoperative morbidity and possibly mortality may be reduced when regional anesthesia is used. Use of regional anesthesia in renal transplantation is still controversial but promising. We assessed the effect of regional anesthesia for 20 cases of renal transplantation. METHODS: 13 patients were operated on under subarachnoid block with continuous epidural anesthesia. Bupivacaine was used for subarachnoid block and lidocaine was used for continuous epidural anesthesia. 7 patients were operated on under only continuous epidural anesthesia. Lidocaine was used for only continuous epidural anesthesia. RESULTS: In 20 cases of renal transplantation regional anesthesia was sufficient for performance of the operation. Stable intraoperative hemodynamics and absence of serious postoperative pulmonary complications were observed in patients operated on under regional anesthesia. Their postoperative analgesia was successfully maintained epidurally. CONCLUSIONS: Our cases show that regional anesthesia has the advantage of stable hemodynamics, fewer postoperative complications and postoperative analgesia.

Diabetes is a rapidly increasing heath care problem all over the world due to increased prevalence during past decade. Diabetic nephropathy develops in 25-30% of patients with type 1 diabetes and is the leading cause of end stage renal disease. Diabetic nephropathy is characterized by persistent proteinuria, decline in renal function, hypertension and increased cardiovascular morbidity and mortality. Early detection of diabetic nephropathy risk is an important goal because early diagnosis and treatment prevent advanced renal damage and other diabetic complications. Increased urinary albumin excretion rate is widely accepted as the first clinical sign of diabetic nephropathy. However, reduced glomerular filtration or hypertension could be the first manifestation in some diabetic patients. We need improved markers and predictors of diabetic nephropathy risk. We report a case of diabetic nephropathy and decreased glomerular filtration rate (GFR) without microalbuminuria occcured in type 1 diabetic patient.

BACKGROUND/AIMS: A revised classification system for renal dysfunction in patients with cirrhosis was proposed by the Acute Dialysis Quality Initiative and the International Ascites Club Working Group in 2011. The aim of this study was to determine the prevalence of renal dysfunction according to the criteria in this proposal. METHODS: The medical records of cirrhotic patients who were admitted to Konkuk University Hospital between 2006 and 2010 were reviewed retrospectively. The data obtained at first admission were collected. Acute kidney injury (AKI) and chronic kidney disease (CKD) were defined using the proposed diagnostic criteria of kidney dysfunction in cirrhosis. RESULTS: Six hundred and forty-three patients were admitted, of whom 190 (29.5%), 273 (42.5%), and 180 (28.0%) were Child-Pugh class A, B, and C, respectively. Eighty-three patients (12.9%) were diagnosed with AKI, the most common cause for which was dehydration (30 patients). Three patients had hepatorenal syndrome type 1 and 26 patients had prerenal-type AKI caused by volume deficiency after variceal bleeding. In addition, 22 patients (3.4%) were diagnosed with CKD, 1 patient with hepatorenal syndrome type 2, and 3 patients (0.5%) with AKI on CKD. CONCLUSIONS: Both AKI and CKD are common among hospitalized cirrhotic patients, and often occur simultaneously (16.8%). The most common type of renal dysfunction was AKI (12.9%). Diagnosis of type 2 hepatorenal syndrome remains difficult. A prospective cohort study is warranted to evaluate the clinical course in cirrhotic patients with renal dysfunction.

BACKGROUND/AIMS: Many studies have compared patients with systemic lupus erythematosus (SLE) on renal replacement therapy (RRT) with non-lupus patients. However, few data are available on the long-term outcome of patients with end-stage renal disease (ESRD) secondary to SLE who are managed by different types of RRTs. METHODS: We conducted a retrospective multicenter study on 59 patients with ESRD who underwent maintenance RRT between 1990 and 2007 for SLE. Of these patients, 28 underwent hemodialysis (HD), 14 underwent peritoneal dialysis (PD), and 17 patients received kidney transplantation (KT). We analyzed the clinical outcomes in these patients to determine the best treatment modality. RESULTS: The mean follow-up period was 5 +/- 3 years in the HD group, 5 +/- 3 years in the PD group, and 10 +/- 5 years in the KT group (p = 0.005). Disease flare-up was more common in the HD group than in the KT group (p = 0.012). Infection was more common in the PD and HD groups than in the KT group (HD vs. KT, p = 0.027; PD vs. KT, p = 0.033). Cardiovascular complications were more common in the HD group than in the other groups (p = 0.049). Orthopedic complications were more common in the PD group than in the other groups (p = 0.028). Bleeding was more common in the HD group than in the other groups (p = 0.026). Patient survival was greater in the KT group than in the HD group (p = 0.029). Technique survival was lower in the PD group than in the HD group (p = 0.019). CONCLUSIONS: Among patients with ESRD secondary to SLE, KT had better patient survival and lower complication rates than HD and lower complication rates than PD. The prognosis between the HD and PD groups was similar. We conclude that if KT is not a viable treatment option, any alternative treatment should take into account the patient's general condition and preference.

Major and profound changes have taken place in China over the past 30 years. Rapid socioeconomic progress has exerted a great impact on lifestyle, ranging from food, clothing, working and living conditions, and means of transportation to leisure activities and entertainment. At the same time, new health problems have emerged, and health services are facing new challenges. Presently, cardiovascular diseases (CVD) are among the top health problems of the Chinese people, and pose a serious challenge to all engaged in the prevention and control of these diseases. An epidemic of CVD in China is emerging as a result of lifestyle changes, urbanization and longevity. Both national policy decision-making and medical practice urgently need an authoritative report which comprehensively reflects the trends in the epidemic of CVD and current preventive measures. Since 2005, guided by the Bureau of Disease Prevention of the Ministry of Health of the People's Republic of China and the National Center for Cardiovascular Diseases of China, nationwide experts in the fields of epidemiology, clinical medicine and health economics in the realms of CVD, cerebrovascular disease, diabetes and chronic kidney disease, completed the Report on Cardiovascular Diseases in China every year. The report aims to provide a timely review of the trend of the epidemic and to assess the progress of prevention and control of CVD. In addition, as the report is authoritative, representative and readable, it will become an information platform in the CVD field and an important reference book for government, academic institutes, medical organizations and clinical physicians. This publication is expected to play a positive role in the prevention and control of CVD in China. We present an abstract from the Report on Cardiovascular Diseases in China (2010), including trends in CVD, morbidity and mortality of major CVDs, up-to-date assessment of risk factors, as well as health resources for CVD, and a profile of medical expenditure, with the aim of providing evidence for decision-making in CVD prevention and control programs in China, and of delivering the most authoritative information on CVD prevention and control for all citizens.

PURPOSE: Cardiac troponin T (cTnT), a useful marker for diagnosing acute myocardial infarction (AMI) in the general population, is significantly higher than the usual cut-off value in many end-stage renal disease (ESRD) patients without clinically apparent evidence of AMI. The aim of this study was to evaluate the clinical usefulness of cTnT in ESRD patients with acute coronary syndrome (ACS). MATERIALS AND METHODS: Two hundred eighty-four ESRD patients with ACS were enrolled between March 2002 and February 2008. These patients were followed until death or June 2009. Medical records were reviewed retrospectively. The cut-off value of cTnT for AMI was evaluated using a receiver operating characteristic (ROC) curve. We calculated Kaplan-Meier survival curves, and potential outcome predictors were determined by Cox proportional hazard analysis. RESULTS: AMIs were diagnosed in 40 patients (14.1%). The area under the curve was 0.98 in the ROC curve (p<0.001; 95% CI, 0.95-1.00). The summation of sensitivity and specificity was highest at the initial cTnT value of 0.35 ng/mL (sensitivity, 0.95; specificity, 0.97). Survival analysis showed a statistically significant difference in all-cause and cardiovascular mortalities for the group with an initial cTnT > or =0.35 ng/mL compared to the other groups. Initial serum cTnT concentration was an independent predictor for mortality. CONCLUSION: Because ESRD patients with an initial cTnT concentration > or =0.35 ng/mL have a poor prognosis, it is suggested that urgent diagnosis and treatment be indicated in dialysis patients with ACS when the initial cTnT levels are > or =0.35 ng/mL.

BACKGROUND/AIMS: It has been suggested that chronic kidney disease (CKD) is a risk factor for Clostridium difficile infection (CDI) and is associated with increased mortality among patients infected with C. difficile. However, recent studies of the clinical impact of CKD on CDI in Asians are still insufficient. We sought to determine the relationship between CKD and CDI in a Korean population. METHODS: This was a single-center, retrospective case-control study. In total, 171 patients with CDI were included as cases and 342 age- and gender-matched patients without CDI were used as controls. We compared the prevalence of CKD in the study sample and identified independent risk factors that could predict the development or prognosis of CDI. RESULTS: Independent risk factors for CDI included stage IV to V CKD not requiring dialysis (odds ratio [OR], 2.90) and end-stage renal disease requiring dialysis (OR, 3.34). Patients with more advanced CKD (estimated glomerular filtration rate < 30) and CDI showed higher in-hospital mortality and poorer responses to the initial metronidazole therapy. CONCLUSIONS: More advanced CKD is an independent risk factor for CDI and is associated with higher in-hospital mortality and poor treatment responses in CDI patients. Thus, in CKD patients, careful attention should be paid to the occurrence of CDI and its management to improve the outcome of CDI.

BACKGROUND: As cardiac disorders, especially coronary artery disease is increasing in end-stage renal disease patients, the indications for coronary artery bypass surgery are increasing now. They have high risks for postoperative morbidity and mortality after coronary artery bypass surgery. MATERIAL AND METHOD: Between March of 1996 and May of 2000, medical records of 25 patients with end-stage renal disease who underwent coronary artery bypass surgery at Asan medical center were reviewed retrospectively. We reviewed the short-term results of preoperative risk factors, preoperative renal function, perative methods, operation results, hospital course, postoperative morbidity and mortality. RESULT: Preoperative creatinine clearance was 12.68+/-5 ml/min and serum creatinine level was 6.18+/-3 mg/dL(range 1.7-14. 4). Preoperatively, 11 patients(44%) received dialysis and the others(14 patients, 56%) were not supported by dialysis due to adequate urine output. Of the non-dialysis patients(14 cases), 8 patients were newly supported by dialysis, perioperatively. Of the preoperative hemodialysis patients(9 cases), two patients changed dialysis method postoperatively to peritoneal dialysis. Operative mortality occured in 2 patients(8%) and the causes of death were sepsis from aspiration pneumonia and mediastinitis, and postoperative bleeding and mediastinitis, respectively. Postoperative complications were developed in 14 patients(56%). There were 2 cases(8%) late mortalities and the cause of death was catheter-induced peritonitis. The actuarial survival rates in hospital survivals at 4 years was 82+/-13%. CONCLUSION: The coronary artery bypass surgery of end-stage renal disease patients were performed with acceptable mortality(8%). However , because the morbidity and mortality from morbidity were very frequent, perioperative prevention of infectious complications and careful patient management are very important.

Malnutrition and inflammation are related to high rates of morbidity and mortality in hemodialysis patients. Resistin is associated with nutrition and inflammation. We attempted to determine whether resistin levels may predict clinical outcomes in hemodialysis patients. We conducted a prospective evaluation of 100 outpatients on hemodialysis in a single dialysis center (male, 46%; mean age, 53.7 +/- 16.4 yr). We stratified the patients into 4 groups according to quartiles of serum resistin levels. During the 18-month observational period, patients with the lowest quartile of serum resistin levels had poor hospitalization-free survival (log rank test, P = 0.016). After adjustment of all co-variables, patients with the lowest quartile of serum resistin levels had poor hospitalization-free survival, compared with reference resistin levels. Higher levels of interleukin-6 were an independent predictor of poor hospitalization-free survival. In contrast, serum resistin levels were not correlated with interleukin-6 levels. The current data showed that low resistin levels may independently predict poor hospitalization free survival in hemodialysis patients.
