[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.]

[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.]

[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.]

[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 complications of percutaneous kidney biopsy and histological diagnosis ]

FISI Viktória, MAZÁK István, DEGRELL Péter, HALMAI Richárd, MOLNÁR Gergő A., FEHÉR Eszter, NÉMETH Kinga, PINTÉR István, KOVÁCS Tibor, WITTMANN István

[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. ]

[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.]

[Thiazide- or thiazide-like diuretics should be used in the treatment of patients with hypertension? Particularities of the situation in Hungary]


[Diuretics have remained the cornerstone of the antihypertensive treatment since their widespreading in the 1960s. According to the 2018 ESC/ESH Guidelines for the management of arterial hypertension, in the absence of evidence from direct comparator trials and recognizing that many of the approved single-pill combinations are based on hydrochlorothiazide, this drug and thiazide-like indapamide can be considered suitable antihypertensive agents. In the 2018 Hungarian guidelines indapamide is named as the most efficacious diuretic in the treatment of patients with hypertension. The aim of the publication is redefining thiazide- and thiazide-like diuretic use in the treatment of hypertensive patients, with particular attention to presently available hydrochlorothia­zide and indapamide, and their combination drugs in Hungary.]

[Monitoring of the blood pressure lowering effectiveness of ramipril-amlodipine fix combination – a non-interventional trial (RAMONA study)]


[Purpose: Monitoring the effectiveness and safety of the fix combination formulation Egiramlon® therapy containing ramipril and amlodipin in patients, suffering from mild or moderate hypertension despite antihypertensive treatment. Patients and methods: Open, prospective, phase IV clinical observational study, which involved 9169 patients (age >18) with mild or moderate hypertension [TUKEB No: 16927- 1/2012/EKU (294/PI/12.)]. Ramipril/Amlodipin 5/5, 5/10, 10/5, 10/10 mg combinations were administered/ titrated in three visits, during the four months period according to the physician’s decision Blood pressure was measured by validated blood pressure sphygmomanometry and ABPM (Meditech, Hungary). The dosis of the fix combination formulation was determined individually during the visits by the 923 doctors involved in the study. The target blood pressure value was 140/90 mmHg, but in case of high risk patients population (diagnosed cardiovascular disease, diabetes), 130/90 mmHg target value was determined. Results: In 70.1% of the patients had no protocoll deviation. Patients data and examination results were processed according to this 6423 patient population. The average age of the patients were 60.2 year, in 50-50% sex distribution. The average duration of the treated hypertension was 9.8 years and the average blood pressure value was 157/91 mmHg. Till the end of the study, systolic blood pressure has decreased with 26.4 mmHg and diastolic pressure with 11.8 mmHg. An average 5.5 bpm heart rate frequency decreasing was observed at the end of the study. As a result of the treatment 52.4% of the patient population has reached the target blood pressure value.]

[Hypertension, COPD and COVID-19. Focus on antihypertensive therapy]


[Chronic obstructive pulmonary disease is a very common comorbidity of hypertension and it is often unrecognised by physicians. The factors involved in the pathomechanism of both diseases should be realised when choosing treatment. Among factors, hypoxia, increased tone of sympathetic nervous system and activation of renin-angiotensin-aldosterone system should primarily be considered. Vascular wall damage and endothelial dysfunction has an important role in both conditions. The goals of treatment are elimination of risk factors, optimizing the blood pressure, the consequential prevention of cardio-cerebrovascular, renal and pulmonary damage; finally prolonging the patients’ life and improving their quality of life as well. Both hypertension and COPD significantly worsen the condition of COVID-19 patients since they increase the severity of the disease and the rate of in-patients’ and their mortality. In the treatment of hypertension among COPD and COVID-19 patients there must be emphasized the medication inhibiting of renin-angiotensin-aldosterone system, such as angiotensin-converting en­zyme inhibitors or angiotensin-II AT1 re­cep­tor antagonists. Special attention concerned the beneficial effect of mineralocorticoid receptor antagonist spironolactone. Other antihypertensive drugs (calcium channel blockers, thiazide-like diu­retics, high selectivity β1 receptor antagonists) may supplement the treatment if necessary. Long-acting β2 receptor agonists, muscarinic receptor antagonists and inhalation corticosteroids may be administered in double or triple combination also in hypertension and COPD as well. It is important to note, that statin therapy and also vitamin D3 improve the condition of COVID-19 patients.]

[May measurement month: analysis of the Hungarian results of years 2017 and 2019]

NEMCSIK János, PÁLL Dénes, JÁRAI Zoltán

[Cardiovascular (CV) diseases are not only the leading causes of mortality in Hungary, but also the mortality rate is excessively high compared with the average of European Union, so screening programs identifying subjects with elevated blood pressure (BP) is of utmost importance. May Measurement Month (MMM) is an annual global initiative which began in 2017 aimed at raising awareness of high BP. Hungary, through the Hungarian Society of Hypertension has joined the campaign of MMM from the beginning. The results of years 2017 and 2019 are presented in this paper. ]
