[Blood presssure paradoxon in very elderly patients]


FEBRUARY 20, 2014

Hypertension and nephrology - 2014;18(01-02)

[The paper is warning for the necessity of very complex consideration before taking antihypertensive therapeutic decisions (indication, point or points of actiou, blood pressure target levels, dynamics of BP reduction, etc) for elderly hypertensive patients. Blood pressure reduction can mean efficient protection against cardiovascular events also among the elderly hypertensives. However in those old and very old hypertensive patients who have not only severe stiffness of their large vessels but suffer in advanced co-morbidities and integrated pathologic geriatric syndromes, the blood pressure reduction can result in sometimes even life threatening general deterioration. Antihypertensive therapeutic dilemmas of elderly caregivers appear mainly in relation to old hypertensive patients of age over 80 years. For this „very old” age period the HYVET study gave us evidence based conclusions about the cardiovascular protective usefulness of combined antihypertensive treatment resulting in BP reduction to 150 Hgmm systolic BP target levels. However a non-negligable rate of selection of the included patients in HYVET study can weaken the generalizability of the HYVET findings in this age period and the extensibility of its antihypertensive therapeutic conclusions for the entire „very old” population because this population has also a high proportion of patients with chronic progressive illnesses and general decline. Thus the elderly hypertensives’ caregiver must always carefully and critically balance between the messages of the HYVET and the nonselective observational follow up studies among elderlies showing frequently the so-called epidemiologic blood pressure/ mortality paradoxon. The paper is also trying to find potencial pathomechanical interpretations and point of actions for the epidemiologic blood pressure/mortality paradoxon found in the very old population.]

[Fenestration of endothelium of juxtaglomerular arteriole]


[For the first time, we demonstrated the fenestration in the endothelium of the distal portion of renal afferent arteriole (AA), which is unusual among high pressure vessels. The fenestrae are co-localized with renin producing granular epithelioid cells; this arrangement makes it likely that the relatively large renin molecules may use this path to enter into the plasma. We also demonstrated that the length and area of this fenestrated segment 1) correlates with the activity of the renin-angiotensin system (RAS), 2) may change by age, in response to some stimuli such as thirst and in some diseases, 3) allows filtration of fluid prior to the glomerular filtration, which can be as high as about 30% of GFR. This morphology and the high filtration volume in AA is one of the most striking observations of renal microcirculation, and question several basic renal physiological issues.]

[Physical activity, physical function and exercise in chronic kidney disease]

NAGY Judit, APOR Péter, KISS István

[This review summarize the decreased physical activity and physical function of chronic kidney disease patients from the early stage of their renal disease; the favourable effects of exercise training on physical activity and function as well as on progression of chronic renal diseases. At the end, there is a recommendation for implementation of exercise in this renal patient population. The conclusion is that, on the basis of the evidences patients with chronic renal disease should be advised to increase their physical activity in all stages of their renal disea]

[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.]

[The benefit of blood pressure lowering to high risk cardiovascular patients is proven. Thiazides are first line agents of blood pressure lowering treatment. Indapamide has both thiazide-like and vasodilator effects. Randomized controlled trials have shown that slow release indapamide of 1.5 mg efficiently lowers blood pressure, as well as the risk of various cardiovascular events (left ventricular hypertrophy, secondary stroke, progression of nephropathy etc.). Due to the low dose, the drug is well tolerated. Slow release indapamide is therefore an ideal choice as monotherapy for the beginning of blood pressure lowering treatment, and it is also a base drug of combination treatments.]

[Telehealth care of high-risk hypertensive patients for a better target blood pressure and smaller size blood pressure fluctuation. Authors conducted a one-year, multicentre, prospective, observational study with no intervention. Their aim was to achieve better targeting and smaller blood pressure fluctuation in patients with high risk hypertensive patients with the new type of doctorpatient co-operation and telemedicinal care than the conventional control method. In the active group, 50 patients, in the non-active group 47 treated hypertensive patients were analysed. During the observation period (1 year) the mean (± SD) of the systolic blood pressure decreased from 143.3 (15.1) mmHg to 134.5 (9.2) mmHg in the active group, but in the non-active group there was no significant decrease. The target blood pressure (< 140/90 mmHg) could be increased from 46% to 62%. The two characteristics of interpersonal visit-to-visit variability index. The standard deviation (SD) and variation coefficient (VC) showed a significant decrease in the active group. There was no change in the inactive group. A method supported by telemedicine-assisted and better patientphysician- assistant co-operation is suitable for increasing target blood pressure rates and reducing blood pressure fluctuation.]

[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.]
