Objective: The conversion of cortisol (F) to cortisone (E) is catalyzed by 11beta-hydroxysteroid dehydrogenase type 2 (11β-HSD2). Children suffering from chronic renal failure (CRF) have a decreased activity of 11β-HSD2 contributing to increased arterial blood pressure. The objective was to investigate whether a normal conversion of F to E is achieved after renal transplantation (TX) in children. Methods: Fifteen children with CRF, 17 children with steroid-free immunosuppression after TX, and 18 healthy controls (CO) were enrolled. The activity of 11β-HSD2 in plasma was calculated using the ratio of F/E determined by tandem mass spectrometry, the ratio of tetrahydrocortisol (THF) +5α-tetrahydrocortisol (5αTHF) in urine determined by gas chromatography/mass spectrometry, and the ratio of (THF +5αTHF)/tetrahydrocortisone (THE) in urine determined by tandem mass spectrometry. Results: The F/E ratio (mean ± s.d./s.e.m.) was significantly higher in CRF and TX (5.6 ± 1.9/0.6, 7.12 ± 3.1/0.9) than in CO (1.18 ± 0.2/0.03, P < 0.0001) groups. The (THF + 5αTHF)/THE ratio in CRF (1.19 ± 1.1/0.5) and TX (1.19 ± 0.1/0.5) groups was significantly higher than in controls (0.21 ± 0.05/0.18, P < 0.0001). Positive correlations between plasma and urinary ratios (P = 0.0004. R2 = 0.73 in CRF, P = 0.0013, R2 = 0.56 in TX, P < 0.0001, R2 = 0.66 in CO) were found, whereas significant correlations between F/E or (THF + 5αTHF)/THE ratios and blood pressure, the number of antihypertensive drugs taken or creatinine clearance could not be found. Conclusions: In all children with chronic renal failure plasma and urinary cortisol/cortisone ratios are elevated and do not return to normal levels after renal allograft transplantation. This suggests that renal transplantation does not normalize 11β-HSD2 activity.

1. Baroreflex sensitivity was evaluated in 22 non-dialysed patients with chronic renal failure secondary to chronic glomerulonephritis. Baroreflex sensitivity was judged by the slope of the linear regression of the pulse interval on the rise in systolic blood pressure with injection of phenylephrine or reduction by amyl nitrite inhalation. 2. Baroreflex sensitivity was reduced in these patients as compared with normal controls. Reduction of baroreflex sensitivity was significantly greater in nine hypertensive than 13 normotensive patients with chronic renal failure. 3. A significant positive correlation was found between baroreflex sensitivity and motor nerve conduction velocity measured on ulnar nerve in 13 patients examined. 4. Saline was given with high dietary salt intake to seven normotensive patients with chronic renal failure for 2 or 5 days in order to determine whether the severe depression of baroreflex sensitivity can be an initiating factor for hypertension. Blood pressure was raised to hypertensive levels within 5 days in two patients in whom baroreflex sensitivity was nearly as low as that of hypertensive patients, but not in five cases whose baroreflex sensitivity was normal or only mildly depressed. Plasma volume increased to the same degree in both groups. Baroreflex sensitivity did not change in the former two cases despite blood pressure elevation. 5. It is concluded that reduced baroreflex sensitivity in chronic renal failure correlated with the presence of hypertension, as well as uraemic neuropathy, and may be one of the pathogenetic mechanisms of hypertension in end-stage chronic glomerulonephritis.

Objective: To review disorders elements of the metabolic syndrome in patients with end-stage chronic renal failure on dialysis cycle. Materials and methods: A cross sectional descriptive study of 85 patients including end-stage chronic renal failure in dialysis cycle from 5/2015 - 9/2016 at the Department of Artificial Kidney, Hue Central Hospital. Results: The prevalence of metabolic syndrome in dialysis patients was 37.65%. The prevalence of abdominal obesity was 30.6%; The prevalence of hypertension was 72.9%, the average value systolic blood pressure and diastolic blood pressure were 142.24 ± 27.53, 80.35 ± 12.48 mmHg; The prevalence of hyperglycemia was 28%, the average value blood glucose was 4.9 ± 1.19 mmol/l; The prevalence of triglyceride increase was 34.1%, the average value triglyceride was 1.59 ± 0.84 mmol/l. The prevalence of HDL-C increase was 47.1%, the average value HDL-C was 1.24 ± 0.33 mmol/l. Conclusion: The prevalence of metabolic syndrome in dialysis patients is very high, in which hypertension and HDL disturbances are the highest.

Background: Cardiovascular diseases are the leading cause of death in patients with chronic renal failure. When a patient undergoes dialysis, making AVF or AVG causes cardiovascular events. Understanding the relationship between complications: hypertension, heart failure, AVF or AVG (formation time, position, diameter) helps us monitor, detect, prevent and treatment of complications to limit the risk of death in patients with dialysis. Objective: Relationship between cardiovascular diseases and anatomosis of arteriovenous fistular in patients with regularly hemodialysis at Cho Ray Hospital. Methods: A cross-sectional study was conducted at Cho Ray Hospital from 2015 to 2016. The survey some cardiovascular diseases are done by clinical examination, tests for diagnostic imaging such as X-ray, electrocardiogram and echocardiogram: heart and diameter of anastomosis AVF, AVG. Results: The study population included 303 patients with chronic renal failure who were dialysis. Of which, patients aged 25-45 accounted for the highest proportion (43.9%). The proportion of male and female patients was similar (48.5% and 51.5% respectively). The mean value of systolic blood pressure on patients made AVF, AVG less than 12 months is higher than patients made AVF, AVG over 12 months, and there is negative correlation (r = -0.43) between AVF, AVG and systolic blood pressure (p <0.05). The mean value of diastolic blood pressure on patients made AVF, AVG less than 12 months is lower than patients made AVF, AVG over 12 months, and and there is positive correlation (r = -0.43) between AVF, AVG and diastolic blood pressure (p <0.05) (p <0.05). The prevalence of patients with heart failure made AVF, AVG over 12 months is higher than that of the under 12 months group, there is a negative correlation (r = - 0.43) between AVF, AVG diameter and EF index (p <0.05). Conclusion: It is important to note the diameter of anastomosis AVF, AVG in patients with chronic renal failure dialysis to limit cardiovascular complications, especially heart failure. Key words: Chronic kidney disease, hemodialysis.
