Article: [Expert consensus statement on interventional renal sympathetic denervation for hypertension treatment].
[show abstract] [hide abstract]
ABSTRACT: This commentary summarizes the expert consensus and recommendations of the working group 'Herz und Niere' of the German Society of Cardiology (DGK), the German Society of Nephrology (DGfN) and the German Hypertension League (DHL) on renal denervation for antihypertensive treatment. Renal denervation is a new, interventional approach to selectively denervate renal afferent and efferent sympathetic fibers. Renal denervation has been demonstrated to reduce office systolic and diastolic blood pressure in patients with resistant hypertension, defined as systolic office blood pressure ≥ 160 mm Hg and ≥ 150 mm Hg in patients with diabetes type 2, which should currently be used as blood pressure thresholds for undergoing the procedure. Exclusion of secondary hypertension causes and optimized antihypertensive drug treatment is mandatory in every patient with resistant hypertension. In order to exclude pseudoresistance, 24-hour blood pressure measurements should be performed. Preserved renal function was an inclusion criterion in the Symplicity studies, therefore, renal denervation should be only considered in patients with a glomerular filtration rate > 45 ml/min. Adequate centre qualification in both, treatment of hypertension and interventional expertise are essential to ensure correct patient selection and procedural safety. Long-term follow-up after renal denervation and participation in the German Renal Denervation (GREAT) Registry are recommended to assess safety and efficacy after renal denervation over time.DMW - Deutsche Medizinische Wochenschrift 11/2011; 136(47):2418. · 0.53 Impact Factor -
Article: Smoking is associated with a high prevalence of microalbuminuria in hypertensive high-risk patients: data from I-SEARCH.
[show abstract] [hide abstract]
ABSTRACT: Microalbuminuria (MAU) is a marker of endothelial dysfunction and a predictor of cardiovascular events. The effects of cigarette smoking on the prevalence of MAU in a high-risk population with arterial hypertension are unclear. The International Survey Evaluating Microalbuminuria Routinely by Cardiologists in patients with Hypertension (I-SEARCH) documented the clinical profile of 20,364 patients with arterial hypertension and cardiovascular risk factors. In this population, 13,690 patients had no history of smoking, 4,057 patients were former smokers and 2,617 patients were current smokers. The prevalence of MAU was associated with the smoking status. Consumption of 1-20 cigarettes per day leads to an increase of 6.8% in the prevalence of MAU compared to non-smokers (P < 0.001). Smoking of >20 cigarettes per day was associated with a 12.5% higher prevalence of MAU compared to non-smokers, while former smokers had a 4.7% higher prevalence of MAU. Multivariable analysis revealed that smoking was independently associated with MAU [odds ratio (OR) smoking vs. non-smoking 1.16; 95% confidence interval (CI) 1.01-1.33; P < 0.05]. Particularly, a consumption of >20 cigarettes per day was associated with high odds for MAU (OR 1.33; CI 1.01-1.75; P < 0.05). Interestingly, independently of blood pressure, the use of an angiotensin receptor blocker and an ACE was associated with significantly reduced odds ratio for MAU in the smoking group, while there was no significant association in the non-smoking group. The prevalence of MAU in hypertensive patients is higher in smokers than in non-smokers with a strong dose dependency.Clinical Research in Cardiology 12/2010; 99(12):825-32. · 2.95 Impact Factor -
Article: [BENEFIT Kidney--significance of a nephrology screening at intervention outset and therapy success].

ABSTRACT: Early specialist care of patients with renal disease, including timely and planned onset of dialysis, determine the course of the disease, quality of life, hospitalization and life expectancy. A multi-centre enquiry by standardized questionnaire was undertaken to define and analyse medical care of newly dialysis-requiring patients. Data on 551 patients in five different regions of Germany who for the first time required renal replacement treatment were prospectively collected between July 2002 and March 2003. Documentation of history, clinical findings and biochemical tests was done on consecutive patients with a standardized questionnaire, until the desired number of cases was reached. The mean age of the patients (55.4% males) was 64.8 years. 30.7% had diabetes mellitus, 22.3% arterial hypertension/nephrosclerosis and 16.9% glomerulonephritis/vasculitis. Early predominantly nephrological care had been undertaken in 38.7% of patients. 59.0% were cared for almost exclusively by their general practitioner until the time when dialysis was started. 229 patients (41.6%) were referred to specialist (nephrologists) only when dialysis had become necessary. The onset of dialysis was at the right time in only 50.5% of this group. Comparing the care given by nephrologists with that by general practitioners, elective (i.e. planned) dialysis was begun in 81.0% vs. 48.0% (p<0.05). Hospitalization in the two groups was 54.5% vs. 83.7% (p<0.05), the duration of hospital stay 11.4 vs. 17.4 days (p<0.05). Fewer than 40% of patients with chronic renal disease in preterminal renal failure (stage IV) were under the care of nephrologists. The lower the degree of nephrological care the more frequent was there a delay in the onset of dialysis treatment. The incidence and the duration of hospital stay was longer. Structured treatment pathways and incentives need to be formulated to reduce the incidence of wrong or substandard treatment of patients with impaired renal function.DMW - Deutsche Medizinische Wochenschrift 04/2005; 130(13):792-6. · 0.53 Impact Factor
