Glomerular filtration rate and/or creatinine are not accurate methods for renal failure prediction. This study tested homocysteine (Hcy) as a predictive and prognostic marker for end stage renal disease (ESRD). In total, 176 subjects were recruited and divided into: healthy normal group (108 subjects); mild-to-moderate impaired renal function group (21 patients); severe impaired renal function group (7 patients); and chronic renal failure group (40 patients) who were on regular hemodialysis. Blood samples were collected, and serum was separated for analysis of total Hcy, creatinine, high sensitive C-reactive protein (CRP), serum albumin, and calcium. Data showed that Hcy level was significantly increased from normal-to-mild impairment then significantly decreases from mild impairment until the patient reaches severe impairment while showing significant elevation in the last stage of chronic renal disease. Creatinine level was increased in all stages of kidney impairment in comparison with control. CRP level was showing significant elevation in the last stage. A significant decrease in both albumin and calcium was occurred in all stages of renal impairment. We conclude Hcy in combination with CRP, creatinine, albumin, and calcium can be used as a prognostic marker for ESRD and an early diagnostic marker for the risk of renal failure.

Background: Cardiovascular disease (CVD) is the most important cause of morbidity and mortality in patients with end stage renal disease (ESRD). Apelin expressed in endothelial and other tissues including brain and kidney is an adipocytokine defined recently and is emerging an important mediator of cardiovascular homeostasis. The aim of this study was to test whether apelin levels might be associated with carotid artery atherosclerosis and left ventricular mass index (LVMI) in peritoneal dialysis patients. Patients and methods: Fifty peritoneal dialysis patients (25 female, mean age 41.4 ± 11.9 years, mean dialysis vintage 65.0 ± 35.4 months) and 18 healthy individuals (9 female, mean age 41.7 ± 6.8 years) were included in this cross-sectional study. Serum apelin 12 levels, echocardiographic findings and carotid intima media thickness (CIMT) were recorded as well as clinical and laboratory data. Results: There were no differences between the patient and the control groups with regard to demographic characteristics. In patient group, LVMI, CIMT, CRP and apelin levels were elevated compared to control group. However there was no association between apelin, LVMI and CIMT. There was a positive correlation between apelin and CRP, which was not statistically significant. When patients were divided into two groups according to the mean serum apelin levels, LVMI, CIMT and CRP were higher in the high apelin group but this difference did not reach statistical significance. Conclusion: We observed an increased inflammation and CVD risk in peritoneal dialysis patients. However, serum apelin levels seem not to be associated with cardiovascular risk in this group of patients. [ABSTRACT FROM AUTHOR]

Hypertension and anemia are common in uremic patients. This article describes a 35-year-old uremic Taiwanese who was admitted to our hospital with refractory hypertension and refractory anemia following chronic hemodialysis for more than two years. He was diagnosed with Kimura's disease finally. Refractory hypertension and refractory anemia were noted over two years before an enlarged inguinal lymph node was observed. The symptoms lead to the diagnosis of Kimura's disease. Unlike most cases, refractory hypertension and refractory anemia were first noted before the inguinal mass and eosinophilia were presented. The inflammatory parameters increased when the disease was active. Steroid treatment was conducted, and the symptoms including hypertension and anemia promptly decreased. To the authors' knowledge, this case is for first one in which Kimura's disease has induced refractory hypertension and anemia in an ESRD patient and in which these symptoms rapidly subsided following steroid treatment. The activity of Kimura's disease is closely related refractory hypertension, suggesting that inflammation may be involved in refractory hypertension and anemia in a dialytic patient with Kimura's disease.
