[Antihypertensive therapy in patients with COPD - the significance of nebivolol]


DECEMBER 20, 2011

Hypertension and nephrology - 2011;15(05)

[The occurrence of hypertension associated with chronic obstructive pulmonary disease (COPD) is increasing. Recognising COPD is important in order to choose the appropriate antihypertensive drugs. Anti-hypertensive drugs that can be used to treat patients with hypertension and COPD include diuretics, ACE-inhibitors, angioten-sine receptor blockers (AT1 receptor antagonists) and calcium antagonists, as well as cardioselective beta blockers, as these drugs decrease total and cardiovascular mortality. Of these agents, the importance of the most cardioselective one, nebivolol should be stressed, as this drug has no clinically significant effect on parameters of respiratory function, and, through its additional effects (namely by increasing the synthesis of NO), it has a beneficial effect on COPD-related deterioration of respiratory functions, haemodynamic alterations (cor pulmonale) and local factors that participate in the respiratory inflammation and endothelial dysfunction.]

[Genetics of isolated steroid-resistant nephrotic syndrome - results of the two decades around the turn of the millennium]

TORY Kálmán, KERTI Andrea, REUSZ György

[Childhood steroid-resistant nephrotic syndrome (SRNS) is a devastating clinical condition which progresses to end-stage renal disease in 30-40% of the cases after a follow up of 10 years. Based on its etiology, two forms can be distinguished, an immune and a genetic form. During the last two decades, mutations of ten genes - encoding mainly podocyte proteins - were identified in the latter group. As the treatment in the immune and genetic forms are different, and only the identification of the causative mutation can reliably distinguish them, it is important to be familiarized with the genotype-phenotype correlations. The aim of the present review is to summarize our current knowledge on the phenotypes linked to the identified genes.]

[Background: Percutaneous renal biopsy is an essential tool in diagnosis and prognosis of renal diseases. It is well-known that this method has potential complications. The connection between complication occurrence related to renal biopsies and histological diagnoses of the biopsy specimen was analyzed in the present study. We also analyzed the distribution of diagnoses in our population. Methods: In this retrospective survey, 353 patients undergoing renal biopsy was studied. Biopsies were performed after marking the site of puncture with ultrasound imaging. Influence of diagnoses and clinical parameters on complications was evaluated. Results: We found a complication rate of 44.5%. In patients with diabetic nephropathy (likelihood ratio (LR) 0.44) or acute tubular necrosis (LR 0.38) a significantly lower rate of complications was found, while patients with thin basement membrane syndrome had more than 6-fold higher risk for evolvement of intrarenal haemorrhage. Patients with acute interstitial nephritis (LR 3.18) or vasculitis (LR 2.88) have a more than 2-fold risk for arteriovenous shunts while in patients with severe arteriosclerosis the occurrence of this complication was lower (LR 0.46). In rapidly progressive glomerulonephritis, arteriovenous shunts evolved also in a significantly higher rate. Conclusion: Patients with vasculitis, rapidly progressive glomerulonephritis, thin basement membrane syndrome or acute interstitial nephritis should be monitored more carefully after renal biopsy due to the significantly higher risk for complications. ]

[Similarities and differences in the renal effects of statins]


[By efficiently reducing serum cholesterol level, statins significantly decrease both cardiovascular morbidity and mortality. Decreasing LDL-cholesterol level by 1% reduces coronary mortality risk by 1%, whereas increasing HDL-cholesterol level by 1% reduces the risk by 3%. At the same time, renal failure significantly increases cardiovascular events and/or mortality compared with the population mean. It is an exciting question whether statins are able to prevent and decelerate the deterioration of kidney function deterioration, preserve GFR and decrease albuminuria. Depending on the strength of their effect, statins have different cholesterollowering capacity (rosuvastatin and atorvastatin are especially effective). An important question is whether these differences can be detected in the renal function as well. The results of experimental data and major clinical trials (e.g. AURORA, PLANET I-II, SHARP) are often controversial. Nevertheless, statin therapy has advantages for patients with kidney diseases, although to a lesser extent than it has in the normal population.]

[Association of body composition and mortality in patients on maintenance dialysis and on waitlist and after kidney transplantation]


[Overweight [body mass index (BMI) = 25-30 kg/m2] and obesity (BMI ≥30 kg/m2) are epidemic in both developed and developing countries. Obesity has been recognized as risk factor for the development and progression of chronic kidney disease and is associated with increased cardiovascular risk and poor survival. Almost 2/3 of maintenance hemodialysis patients die within five years of commencing dialysis treatment. Although patients on the waitlist having less severe comorbidities than their non-listed counterparts, the death rate remains high while it can take years for an organ donation. In patients with end stage renal disease (ESRD) undergoing maintenance hemodialysis an “obesity paradox” has been consistently reported, i.e., a high BMI is incrementally associated with better survival. Overweight and obesity are highly prevalent in patients at the time of kidney transplantation. Indeed, most transplant centers in US may suspend wait-listing of obese patients with a BMI above 30 or 35 kg/m2 and refer them for weight reduction procedures such as bariatric surgery as a contingency for the transplant surgery. The effect of pre- and post-transplant obesity in kidney transplanted patients on long-term graft and patient survival has not been well established. We have reviewed and summarized salient recent data pertaining to body composition and clinical outcomes about the association of survival and body composition in transplant-waitlisted dialysis patients and kidney transplanted recipients. ]

[Association between cyclothymic affective temperament and hypertension]


[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]

[Modalities of the therapy of patients with high cardiovascular risk]


[International and Hungarian guidelines emphasize the need of the combinations in the therapy of hypertension. Single pill combinations (SPC) are preferred. The importance of the treatment reducing cardiovascular risk is underlined by the fact that in most hypertensive patients other cardiovascular risk factors, among them most frequently dyslipidemia is present. In addition to antihypertensive drugs these patients should be treated also with those decreasing plasma lipids. Adherence / persistence to therapy of patients is greatly improved by the use of single pill combinations. Today we also have SPCs decreasing both, blood pressure and plasma lipids. Among them there is the combination containing amlodipine and atorvastatin. Several international and Hungarian clinical studies have been conducted. Results of these investigations have been described in several publications. In this paper I summarise the most important results of some of these studies. ]

[The importance of recognition and proper treatment of hypertension and the maintenance of adherence in hypertension care]

NEMCSIK János, PÁLL Dénes, JÁRAI Zoltán

[Hypertension is the leading cause of death and disability-adjusted life years. In the United States hypertension accounts for more cardiovascular (CV) deaths than any other modifiable CV disease risk factor and was second only to cigarette smoking as a preventable cause of death for any reason. In our country the situation is similar. In Hungary the number of subjects with hypertension is approximately 3.5 million and this high prevalence contributes markedly to the poor Hungarian CV morbidity and mortality figures. The recognition of hypertension, the initiation of drug therapy and the long-term follow- up of the patients is mainly the task of primary care. Besides that it inheres high responsibility, this is also a grateful commitment, as hypertension in most of the cases can be treated properly with lifestyle-changes and medications leading to a marked decrease of CV complications, especially stroke. In our review article we would like to focus on the high prevalence of hypertension worldwide as well as in our country, the exact implementation of screening, the risk reduction potential of the proper treatment and the importance of the long-term maintenance of treatment adherence.]

[Treatment and care of hypertensive patients during and after the Covid-19 pandemic. Possibilities and effectiveness of telemedicine]


[The course and outcome of an pandemic caused by coronaviruses are determined by many factors, such as the strength and dose of the infectious virus, the immune system of the affected individual, the underlying diseases, the speed of virus spread, age and environmental factors and methods of control. In old age, there is a significantly higher risk of developing severe cases and fatalities. The rate of loss of life is particularly high in social care and nursing homes. Hypertension as the underlying disease is the most common cause of death, but hypertension alone is not an independence risk factor, but the main reason is the co-morbidities and complications associated with viral infection. In the epidemic situation, the treatment and care of hypertensive patients poses special challenges for health and active primary and specialist care workers and, of course, for hypertonologists. The Hungarian Society of Hypertension expressed its opinions and recommendations to patients living at home and to doctors performing treatment and care during the Covid-19 virus epidemic and summarized the decision-making possibilities derived from the data obtained during the telemedicine consultation. We would like to present the details of the possibilities provided by telemedicine, the practical possibilities and advantages of the different methods of teleconsultation, and the models that can be implemented in a domestic environment. We have taken into account international experience to date, the new e-health strategy for chronic, non-communicable diseases and the WHO concept. Telemedicine, continuous teleconsultation ensures an optimal relationship between the patient and the doctor, increases the patient’s sense of security, improves drug adherence. The doctor receives reliable data about the patient’s condition and can send him instructions as well as information. The development of a harmonious balance between personal contact and telecommunications already shows the future, and the application of these methods must be developed in the epidemic-free period as well. Previous international (TASMINH-4, HOMED-BP etc.) and domestic (CONADPER-HU) studies have proved that telemonitoring of hypertensive patients can be successfully solved, improves patients’ drug adherence, increases the target blood pressure achievement rate and at the same time the patient will be the active part of the treatment. The method is especially useful in rural settlements without a doctor. Telemedicine monitoring of elderly and multimorbid patients is especially useful in social institutions and nursing homes. It is solved the continuous control of vital functions, ensures continuity of contact with the supervising physician and in urgent cases, allows for rapid intervention. Telemedicine is also of great importance due to the lack of human resources, as many things can be solved with such technology, there are no need so many personal encounters. In addition to influencing the course of this pandemic, it also plays an important role in efficiency, headcount, management and “convenience” in general practice and in all formes of medicine. The proposed models can not only be applied in an epidemic situation, but should continue to be part of everyday health work in future.]

[Advantages of fixed combinations in the treatment of hypertensive patients]


[In 60-70% of patients with hypertension, a significant decrease in blood pressure can only be achieved by a combination of antihypertensive drugs. International as well as national guidelines emphasise the numerous advantages and the importance of combination treatment. Fixed combinations are particularly advantageous, as their use improves patients’ compliance. This paper summarises the available information on the possible combinations of the nine major antihypertensive drug groups distributed in Hungary, and for details the results published on the recently approved and introduced fixed combination of telmisartan and amlodipine.]
