Accurate measurement of the volume status in hemodialysis patients is important as it can affect mortality. However, no studies have been conducted regarding volume management in cases where a sudden change of body fluid occurs, such as during puerperium in hemodialysis patients. This report presents a case in which the patient was monitored for her body composition and her volume status was controlled using a body composition monitor (BCM) during the puerperal period. This case suggests that using a BCM for volume management may help maintain hemodynamic stability in patients with a rapidly changing volume status for a short term period, such as during puerperium.

Kidney cortex necrosis is a relatively rare cause of acute kidney injury and is characterized by complete or partial destruction of the renal cortex, but sparing of the medulla. Tranexamic acid has antifibrinolytic activity and is used to reduce bleeding. We report a rare case of kidney cortex necrosis caused by tranexamic acid. A 49-year-old woman complained of coughing up blood-tinged sputum. She had a history of bronchiectasis and was treated with tranexamic acid for 3 days. Four days after admission, she developed anuria and azotemia. Computerized tomography showed enhancement of the renal medulla, but not the bilateral renal cortex. The patient was treated with hemodialysis, and has since been maintained on hemodialysis for 6 months. Due to the development of kidney cortex necrosis in patients treated with tranexamic acid, all its potential complications should be considered.

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.

Type B insulin resistance syndrome is rare autoimmune disease that is characterized by various abnormalities of glycemic homeostasis, from hyperglycemia caused by extreme insulin resistance to fasting hypoglycemia. It can combine with other autoimmune diseases, most commonly systemic lupus erythematosus. It usually occurs in women and accompanies acanthosis nigricans, hyperandrogenism, and, in many cases, ovary dysfunction. The diagnosis of type B insulin resistance syndrome is based largely on the presence of insulin receptor autoantibodies and hyperglycemia, or hypoglycemia and hyperinsulinemia. In some cases, patients with the type B insulin resistance have been successfully treated with immunosuppressive therapy and plasmapheresis. We experienced type B insulin resistance syndrome in a patient with chronic hepatitis B and used only plasmapheresis for treatment. The immunosuppressive therapy was omitted due to the state of activation of chronic hepatitis B. We present this case with a review of relevant literature.

BACKGROUND AND OBJECTIVES: The prognostic impact of left axis deviation (LAD) on clinical outcomes in acute heart failure syndrome (AHFS) with left bundle branch block (LBBB) is unknown. The aim of this study was to determine the prognostic significance of axis deviation in acute heart failure patients with LBBB. METHODS: Between March 2011 and February 2014, 292 consecutive AHFS patients with LBBB were recruited from 10 tertiary university hospitals. They were divided into groups with no LAD (n=189) or with LAD (n=103) groups according to QRS axis < −30 degree. The primary outcome was all-cause mortality. RESULTS: The median follow-up duration was 24 months. On multivariate analysis, the rate of all-cause death did not significantly differ between the normal axis and LAD groups (39.7% vs. 46.6%, adjusted hazard ratio, 1.01; 95% confidence interval, 0.66, 1.53; p=0.97). However, on the multiple linear regression analysis to evaluate the predictors of the left ventricular ejection fraction (LVEF), presence of LAD significantly predicted a worse LVEF (adjusted beta, −3.25; 95% confidence interval, −5.82, −0.67; p=0.01). Right ventricle (RV) dilatation was defined as at least 2 of 3 electrocardiographic criteria (late R in lead aVR, low voltages in limb leads, and R/S ratio < 1 in lead V5) and was more frequent in the LAD group than in the normal axis group (p < 0.001). CONCLUSIONS: Among the AHFS with LBBB patients, LAD did not predict mortality, but it could be used as a significant predictor of worse LVEF and RV dilatation (Trial registry at KorAHF registry, ClinicalTrial.gov, NCT01389843).

BACKGROUND/AIMS: Data regarding the outcomes of primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) in nonagenarians are very limited. The aim of the present study was to evaluate the temporal trends and in-hospital outcomes of primary PCI in nonagenarian STEMI patients. METHODS: We retrospectively reviewed data from the Korea Acute Myocardial Infarction Registry (KAMIR) from November 2005 to January 2008, and from the Korea Working Group on Myocardial Infarction (KorMI) from February 2008 to May 2010. RESULTS: During this period, the proportion of nonagenarians among STEMI patients more than doubled (0.59% in KAMIR vs. 1.35% in KorMI), and the rate of use of primary PCI also increased (from 62.5% in KAMIR to 81.0% in KorMI). We identified 84 eligible study patients for which the overall in-hospital mortality rate was 21.4% (25.0% in KAMIR vs. 20.3% in KorMI, p = 0.919). Multivariate analysis identified two independent predictors of in-hospital mortality, namely a final Thrombolysis in Myocardial Infarction (TIMI) flow < 3 (odds ratio [OR], 13.7; 95% confidence interval [CI], 3.2 to 59.0; p < 0.001) and cardiogenic shock during hospitalization (OR, 6.7; 95% CI, 1.5 to 30.3; p = 0.013). CONCLUSIONS: The number of nonagenarian STEMI patients who have undergone primary PCI has increased. Although a final TIMI flow < 3 and cardiogenic shock are independent predictors of in-hospital mortality, primary PCI can be performed with a high success rate and an acceptable in-hospital mortality rate.

This study was performed to evaluate the effects of diabetes on short- and mid-term clinical outcomes in patients with acute myocardial infarction (AMI). Between October 2005 and December 2009, a total of 22,347 patients with AMI from a nationwide registry was analyzed. At the time point of the day 30 after AMI onset, landmark analyses were performed for the development of major adverse cardiovascular events (MACEs), including death, re-infarction and revascularization. In this cohort, 6,131 patients (27.4%) had diabetes. Short-term MACEs, which occurred within 30 days of AMI onset, were observed in 1,364 patients (6.1%). Among the 30-day survivors (n = 21,604), mid-term MACEs, which occurred between 31 and 365 days after AMI onset, were observed in 1,181 patients (5.4%). After adjustment for potential confounders, diabetes was an independent predictor of mid-term MACEs (HR, 1.25; 95% CI, 1.08-1.45; P = 0.002), but not of short-term MACEs (HR: 1.16; 95% CI: 0.93-1.44; P = 0.167). Diabetes is a poor prognostic factor for mid-term clinical outcomes but not for short-term outcomes in AMI patients. Careful monitoring and intensive care should be considered in diabetic patients, especially following the acute stage of AMI.

BACKGROUND AND OBJECTIVES: Metabolic syndrome (MetS) increases the risk of heart failure (HF). The purpose of this study was to identify the prevalence of MetS in patients with HF and determine the syndrome's association with HF in clinical and laboratory parameters. SUBJECTS AND METHODS: A total of 3200 HF patients (67.6+/-14.5 years) enrolled in a nationwide prospective Korea HF Registry between Jan. 2005 and Oct. 2009. Patients were divided into two groups according to the presence or absence of MetS at admission: group I (presence, n=1141) and group II (absence, n=2059). RESULTS: The prevalence of MetS was 35.7% across all subjects and was higher in females (56.0%). The levels of white blood cells, platelets, creatinine, glucose, and cholesterol were significantly higher in group I than in group II. Left ventricular dimension and volume was smaller and ejection fraction was higher in group I than in group II. An ischemic cause of HF was more frequent in group I. The rates of valvular and idiopathic cause were lower in group I than in group II. The rate of mortality was lower in group I than in group II (4.9% vs. 8.3%, p<0.001). CONCLUSION: Despite the increased cardiovascular risks in MetS, MetS was found to be associated with decreased mortality in HF.
