[Elderly patients with end-stage renal disease, its epidemiology and questions regarding it in Hungary]

SZEGEDI János, KISS István

[The number of elderly people and the kidney disease’s importance connected to it has increased worldwide, therefore the chronic kidney disease became an endemic. Parallel to the dwindling of population the people in it age. Because of the men’s higher mortality rate the proportion of women in the elderly is greater. Prognosis indicates that by 2060 every third citizen will be aged 65 or more. Between 1990 and 2015 the life expectancy at birth increased by 6.95 years in the case of men (in 1990 it was 61.13, and in 2015 it was 72.08) and by 4.9 years in the case of women (in 1990 it was 73.7, and in 2015 it was 78.6) in Hungary. Chronic kidney disease concerns 10 to 14 % of the population and 1% of all of them suffers from end stage kidney failure. In the end of 2015 3.52 million patients received kidney replacement therapy around the globe (2.42 million received hemodialysis, 329000 received peritoneal dialysis and 704 000 lived with transplanted kidneys). Of all the risk factors of chronic kidney disease age, hypertension, diabetes mellitus and obesity stand out as the most important ones. The kidneys’ anatomy and function change in elderly age, making it possible for the kidney disease to manifest in greater numbers. The elderly dialysis patients’ number increases worldwide which is connected to their higher life expectancy and better life prospects which on the other hand ultimately means that more and more patient lives to suffer from kidney disease. It cannot be disregarded either that the increasing number of elderly patients suffering from hypertension or diabetes means that because these are causes of kidney disease, the latter’s numbers are also increasing. International data indicates that in the case of incident ESRD patients their number was between 68-2784 and the older than 75 years was 142-1660 per million population. In Hungary there was 778/pmp and 677/pmp, respectively. In 2015 the ratio of incident dialysis patients the ones aged above 65 was 58,9% in the case of incident patients and 50,3% in the case of prevalent patients. The ratio of the ones aged above 75 was 28,2% in the case of incident patients and 22,6% in the case of prevalent patients. The number of elderly dialysis patients differs by region too. Dialysis treatment started in elderly age requires special knowledge and teamwork, similarly to the question of refusing the treatment. The latter team work, adequate experts (doctors and nurses) and the related professions’ representatives build the foundations of a proper clinical practice.]

[First experiences with percutaneous renal denervation in management of resistant hypertension]

SCHULCZ Domonkos, NAGY Ferenc Tamás, THURY Attila, BAJCSI Dóra, FEJES Imola, LETOHA Annamária, CONSTANTINOU Kypros, UNGI Imre, ÁBRAHÁM György, LÉGRÁDY Péter

[Percutaneous transluminal radiofrequency renal denervation is a promising new therapeutic method for the treatment of primary resistant hypertension. The intervention decreases the systemic sympathetic over activation and thus arterial blood pressure. In the 1st Department of Medicine of the University of Szeged, 9 resistant hypertensive patients (2 male, 7 female; mean age: 55.0±4.0 years) had all the conditions were required for renal denervation at the time of interventions were performed. We measured the blood pressure together with the heart rate of the patients on the day preceding the intervention, right after the intervention, at discharge from hospital, then at months 6, 9 and 15. The mean blood pressure was 178/107±7/5 mmHg before the intervention. After denervation mean blood pressure decreased right after the intervention, at discharge from hospital, as well as at months 6, 9 and 15, respectively -15/-17 mmHg; -36/-16 mmHg; -19/-9 mmHg; -27/-21 mmHg and -15/- 16 mmHg. Besides decreasing of blood pressure, the antihypertensive drug therapy also decreased, however, it was not the primary aim of the intervention. No denervation- related intra- or perivascular complications were detected. The findings of our study proved the efficacy and safety of renal denervation in the treatment of primary resistant hypertension, of course with an appropriate patient selection. Our study was not relevant to determine whether this method is accompanied with a significant decrease of cardiovascular morbidity and mortality. Answers may come only based on randomized sham controlled studies with great case numbers.]

[Efficacy of a fixed-dose association of amlodipine and lisinopril in grade II and III hypertensive patients]

JOÃO Maldonado, TEIMO Pereira, MARGARIDA Carvalho

[We conducted an observational study, with ambulatory blood pressure monitoring (ABPM), to evaluate the efficacy of a fixed-dose combination of Amlodipine (5 mg) and Lisinopril (20 mg) in grade II and III hypertensive patients, over an 8 week intervention period. Thirty non-medicated hypertensive patients were enrolled, 36% female, with a mean age of 52.44±11.54 years, a body mass index of 28.73±4.54 kg/m2, and brachial office systolic (SBP) and diastolic (DBP) blood pressure of 174.43±15.06 mmHg and 102.83±10.67 mmHg, respectively. All patients performed a 24 hours ABPM at baseline and after a treatment period of 8 weeks with the fixed-dose association. Brachial office blood pressure and routine blood and urine samples were also obtained in both moments. A significant reduction in blood pressure was observed after the treatment with the fixed-dose association. The proportion of patients with controlled ambulatory blood pressure after the treatment was 69%, considering the normalization of the systolic and diastolic ambulatory pressures over the daytime, nighttime and 24 hours. Considering the brachial office blood pressures, the proportion of controlled hypertensive patients reached 79%. A significant improvement was also seen in microalbuminuria (reduction of 37.40 mg/24h; IC: 2.82-71.97; p=0.035) and fasting glycaemia (reduction of 11.53 mg/dl; IC: 3.46-19.61; p=0.007). No side effects were reported during the 8 week treatment period. The treatment of grade II and III hypertensive patients with a fixed-dose association of Amlodipine (5 mg) and Lisinopril (20 mg) during 8 weeks is effective controlling blood pressure. Furthermore, evidences indicate that the efficacy of the association is achieved quickly, safely and with good tolerability.]

Evaluation of anxiety, depression and marital relationships in patients with migraine

DEMIR Fıgen Ulku, BOZKURT Oya

Aim - The aim of this study was to evaluate the frequency and characteristics of attacks in patients with migraine, to determine the effects of anxiety or depressive symptoms, and to evaluate the marital relationships of patients with migraine. Method - Thirty patients who were admitted to the neurology outpatient clinic of our hospital between July 2018 and October 2018 and were diagnosed with migraine according to the 2013 International Headache Society (IHS) diagnostic criteria were included in this cross-sectional study. Age, sex, headache frequency and severity, depressive traits, marital satisfaction and anxiety status were examined. We used the Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Maudsley Marital Questionnaire (MMQ) and Visual Analogue Scale (VAS) for measuring relevant parameters. Results - The mean severity of migraine pain according to VAS scale was 6.93 ± 1.41 and the mean number of migraine attacks was 4.50 ± 4.24. The mean BDI score of the patients was 12.66 ± 8.98, the mean MMQ-M score was 19.80 ± 12.52, the mean MMQ-S score was 13.20 ± 9.53, the mean STAI-state score was 39.93 ± 10.87 and the mean STAI-trait score was 45.73 ± 8.96. No significant correlation was found between age, number of migraine attacks, migraine duration, migraine headache intensity, and BDI, STAI and MMQ scores (p>0.05). But there was a positive correlation between MMQ-S and scores obtained from the BDI and STAI-state scales (p<0.05). Conclusion - In this study more than half of the migraine patients had mild, moderate or severe depression. A positive correlation was found between sexual dissatisfaction and scale scores of depression and anxiety.

[Education and psychological support of parents in cases of postnatally detected Down syndrome]

MÁTÉ Orsolya, KÍVÉS Zsuzsanna, OLÁH András, FULLÉR Noémi, PAKAI Annamária

[OBJECTIVE - Since the 60’s several publications dealt with the phenomenon how physicians inform parents of newborns about postnatal recognition of Down’s syndrome and the support they receive right after breaking the bad news. Howe - ver, the rest of these studies concentrated on surveying parental satisfaction, while relatively few international studies deal with the other side of the communicational situation, the opinion of the informer. Our study focused on the circumstances of parental information in Hungarian institutions of obstetrics in order to evaluate the possibilities for interventions. METHODS - The Down’s team operating at the University of Pécs Faculty of Health Sciences carried out a national survey in 2005 - an interview-based questionnaire filled by physicians of institutions of obstetrics - with the help of the National Register for Congenital Diseases of the National Centre for Epidemiology and Down’s Foun dation. RESULTS - The coverage of the survey reached 74%. Rest of the surveyed institutions did not have information protocol, however, 70% of them believes it would be necessary. Only 44% of the physicians received communication training and 81% of them believe they can manage communication, 33% have felt that the mother of a newborn with Down’s syndrome would expect special help that the institutions are unable to provide. CONCLUSION - There are serious problems with the circumstances of parental informing in Hungarian institutions of obstetrics. This situation would obviously require intervention. An aimed communicational training based on international experience and exploiting the openness of physicians, as well as the establishment of information protocol could be elements of such intervention.]
