[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.]

[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.]

Simultaneous subdural, subarachnoideal and intracerebral haemorrhage after rupture of a peripheral middle cerebral artery aneurysm

BÉRES-MOLNÁR Anna Katalin, FOLYOVICH András, SZLOBODA Péter, SZENDREY-KISS Zsolt, BERECZKI Dániel, BAKOS Mária, VÁRALLYAY György, SZABÓ Huba, NYÁRI István

The cause of intracerebral, subarachnoid and subdural haemorrhage is different, and the simultaneous appearance in the same case is extremely rare. We describe the case of a patient with a ruptured aneurysm on the distal segment of the middle cerebral artery, with a concomitant subdural and intracerebral haemorrhage, and a subsequent secondary brainstem (Duret) haemorrhage. The 59-year-old woman had hypertension and diabetes in her medical history. She experienced anomic aphasia and left-sided headache starting one day before admission. She had no trauma. A few minutes after admission she suddenly became comatose, her breathing became superficial. Non-contrast CT revealed left sided fronto-parietal subdural and subarachnoid and intracerebral haemorrhage, and bleeding was also observed in the right pontine region. The patient had leucocytosis and hyperglycemia but normal hemostasis. After the subdural haemorrhage had been evacuated, the patient was transferred to intensive care unit. Sepsis developed. Echocardiography did not detect endocarditis. Neurological status, vigilance gradually improved. The rehabilitation process was interrupted by epileptic status. Control CT and CT angiography proved an aneurysm in the peripheral part of the left middle cerebral artery, which was later clipped. Histolo­gical examination excluded mycotic etiology of the aneu­rysm and “normal aneurysm wall” was described. The brain stem haemorrhage – Duret bleeding – was presumably caused by a sudden increase in intracranial pressure due to the supratentorial space occupying process and consequential trans-tentorial herniation. This case is a rarity, as the patient not only survived, but lives an active life with some residual symptoms.

[Zonisamide: one of the first-line antiepileptic drugs in focal epilepsy ]

JANSZKY József, HORVÁTH Réka, KOMOLY Sámuel

[Chronic administration of antiepileptic drugs without history of unprovoked epileptic seizures are not recommended for epilepsy prophylaxis. Conversely, if the patient suffered the first unprovoked seizure, then the presence of epileptiform discharges on the EEG, focal neurological signs, and the presence of epileptogenic lesion on the MRI are risk factors for a second seizure (such as for the development of epilepsy). Without these risk factors, the chance of a second seizure is about 25-30%, while the presence of these risk factors (for example signs of previous stroke, neurotrauma, or encephalitis on the MRI) can predict >70% seizure recurrence. Thus the International League Against Epilepsy (ILAE) re-defined the term ’epilepsy’ which can be diagnosed even after the first seizure, if the risk of seizure recurrence is high. According to this definition, we can start antiepileptic drug therapy after a single unprovoked seizure. There are four antiepileptic drugs which has the highest evidence (level „A”) as first-line initial monotherapy for treating newly diagnosed epilepsy. These are: carbamazepine, phenytoin, levetiracetam, and zonisamide (ZNS). The present review focuses on the ZNS. Beacuse ZNS can be administrated once a day, it is an optimal drug for maintaining patient’s compliance and for those patients who have a high risk for developing a non-compliance (for example teenagers and young adults). Due to the low interaction potential, ZNS treatment is safe and effective in treating epilepsy of elderly people. ZNS is an ideal drug in epilepsy accompanied by obesity, because ZNS has a weight loss effect, especially in obese patients.]

[Association between cyclothymic affective temperament and hypertension]

NEMCSIK János, BATTA Dóra, KŐRÖSI Beáta, RIHMER Zoltán

[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.]

Risk factors for ischemic stroke and stroke subtypes in patients with chronic kidney disease

GÜLER Siber, NAKUS Engin, UTKU Ufuk

Background - The aim of this study was to compare ischemic stroke subtypes with the effects of risk factors, the relationship between grades of kidney disease and the severity of stroke subtypes. Methods - The current study was designed retrospectively and performed with data of patients who were hospitalised due to ischemic stroke. We included 198 subjects who were diagnosed with ischemic stroke of Grade 3 and above with chronic kidney disease. Results - In our study were reported advanced age, coronary artery disease, moderate kidney disease as the most frequent risk factors for cardioembolic etiology. Hypertension, hyperlipidemia, smoking and alcohol consumption were the most frequent risk factors for large-artery disease. Female sex and anaemia were the most frequent risk factors for small-vessel disease. Dialysis and severe kidney disease were the most frequent risk factors in unknown etiologies, while male sex, diabetes mellitus, prior stroke and mild kidney disease were the most frequent risk factors for other etiologies. National Institute of Health Stroke Scale (NIHSS) scores were lower for small-vessel disease compared with other etiologies. This relation was statistically significant (p=0.002). Conclusion - In order to improve the prognosis in ischemic stroke with chronic kidney disease, the risk factors have to be recognised and the treatment options must be modified according to those risk factors.
