The Global Cardiometabolic Risk Profile in Patients with hypertension disease (GOOD) survey investigated the global cardiometabolic risk profile in 3464 adult outpatients with hypertension across 289 sites in 12 European countries. The pulse pressure and heart rate profile of the survey population was evaluated according to the presence or absence of metabolic syndrome and/or type 2 diabetes mellitus. History and treatment of hypertension were not counted as criteria for metabolic syndrome as they applied to all patients. Out of the 3370 recruited patients, 1033 had metabolic syndrome and 1177 had neither metabolic syndrome nor diabetes. When compared with patients with no metabolic syndrome or diabetes, patients with metabolic syndrome had higher pulse pressure (59±14 vs 55±14 mm Hg) and heart rate (75.2±11.0 vs 72.5±10.0 beats per min) (P<0.001 for both), independent of the concomitant presence or absence of diabetes, despite a more prevalent use of β-blockers. In conclusion, in hypertensive outpatients the presence of metabolic syndrome is associated with increased heart rate and pulse pressure, which may at least in part reflect increased arterial stiffness and increased sympathetic tone. This may contribute, to some extent, to explaining the increased cardiovascular risk attributed to the presence of metabolic syndrome. © 2013 Macmillan Publishers Limited.

Background: The development of erythropoiesis-stimulating agents (ESAs) with extended serum half-lives has allowed marked prolongation of the administration intervals. The level of oxidative stress is increased in chronic kidney disease, and is reportedly decreased after long-term ESA treatment. However, the effect of different dosing regimens of ESAs on oxidative stress has not been elucidated. Methods: Five-sixths nephrectomized (NX) rats received either 0.4 μg/kg darbepoetin alfa (DA) weekly or 0.8 μg/kg DA fortnightly between weeks 4 and 10. NX animals receiving saline and a sham-operated (SHAM) group served as controls. The levels of oxidized and reduced glutathione (GSSG, GSH) were followed from blood samples drawn fortnightly. Results: During the follow-up, the ratios GSSG/GSH showed similar trends in both DA groups, levels being significantly lower than those in the SHAM group at weeks 8 and 10. GSSG levels were lower than the baseline throughout the study in all groups except for NX controls. The GSH levels were increased in all three NX groups (weeks 6-10) compared with both the baseline and the SHAM group Conclusion: Our results suggest that the extent of oxidative stress is similar in response to different dosing regimens of DA in 5/6 NX rats when comparable hemoglobin levels are maintained. These findings remain to be confirmed in chronic kidney disease patients. © 2012 Japanese Society of Nephrology.

There has been a steady increase in the prevalence of adolescent hypertension in recent years. In order to prevent target organ damages, it is important to determine the group of hypertensive adolescents. If repeatedly elevated blood pressure values are observed, with special emphasis on white coat hypertension, which is particularly frequent at this age, ambulatory blood pressure monitoring is highly recommended before pharmacological treatment is started. In addition, performing ambulatory blood pressure monitoring is recommended with target organ damage, resistance to therapy, and suspicion of secondary hypertension. The results of the widely available, simple-to-use device are easy to reproduce. Copyright © 2011 S. Karger AG.

AimsLimited information is available on office and ambulatory blood pressure (BP) control as well as on cardiovascular (CV) risk profile in treated hypertensive patients living in central and eastern European countries.Methods and resultsIn 2008, a survey on 7860 treated hypertensive patients followed by non-specialist or specialist physicians was carried out in nine central and eastern European countries (Albania, Belarus, Bosnia, Czech Republic, Latvia, Romania, Serbia, Slovakia, and Ukraine). Cardiovascular risk assessment was based on personal history, clinic BP values, as well as target organ damage evaluation. Patients had a mean (±SD) age of 60.1 ± 11 years, and the majority of them (83.5) were followed by specialists. Average clinic BP was 149.3 ± 17/88.8 ± 11 mmHg. About 70 of patients displayed a very high-risk profile. Electrocardiogram was performed in 99 of patients, echocardiography in 65, carotid ultrasound in 24, fundoscopy in 68, and search for microalbuminuria in 10. Ambulatory BP monitoring was performed in about one-fifth of the recruited patients. Despite the widespread use of combination treatment (87 of the patients), office BP control (<140/90 mmHg) was achieved in 27.1 only, the corresponding control rate for ambulatory BP (<130/80 mmHg) being 35.7. Blood pressure control was (i) variable among different countries, (ii) worse for systolic than for diastolic BP, (iii) slightly better in patients followed by specialists than by non-specialists, (iv) unrelated to patients' age, and (v) more unsatisfactory in high-risk hypertensives and in patients with coronary heart disease, stroke, or renal failure.ConclusionThese data provide evidence that in central and eastern European countries office and ambulatory BP control are unsatisfactory, particularly in patients at very high CV risk, and not differ from that seen in Western Europe. They also show that assessment of subclinical organ damage is quite common, except for microalbuminuria, and that combination drug treatment is frequently used. © 2011 The Author.

Aims: This survey was conducted to assess psychosocial problems and functional status among patients on maintenance dialysis in Hungary. Methods: All adult patients (n = 4,321) receiving maintenance dialysis in the 56 dialysis centers in Hungary in 2006 were approached to participate in a national, cross-sectional survey. Patients completed a brief self-reported questionnaire. Socio-demographic parameters, disease-related information and data about functional status were collected. Self-rated health and depressive symptoms were also assessed. Results: Mean age was 62 ± 14 y; 52% were males. The prevalence of diabetes was 30%. 46% of participants reported having depressive symptoms. Significant functional limitation was frequent. In multivariable regression models, female gender, poor self-reported finances, less education, history of acute myocardial infarction (AMI) or cerebrovascular disease, the presence of visual or hearing impairment and difficulties with basic activities of daily living were independently associated with the presence of depressive symptoms. In a separate model, age, dialysis vintage, history of AMI or cerebrovascular disease, the presence of visual or hearing impairments, difficulties with basic activities of daily living and also having depressive symptoms were independently associated with self-rated health score. Conclusions: Chronic dialysis patients in Hungary have disadvantaged socioeconomic status, frequent depressive symptoms and many functional limitations. Professional psychosocial help would be particularly important for this underprivileged patient population in addition to high quality dialysis to optimize outcomes. © 2011 Dustri-Verlag Dr. K.
