[Perinatal faulty hormonal imprinting: early impact, late consequences]

CSABA György

[The description and basic study of hormonal imprinting were the first in the series of research, which led to the recognition of the role of perinatal chemical effects in the late (adult age) manifestation of some diseases and inclination to diseases. Today it is clear, that certain pathological states, as obesity or diabetes, hypo- or hyperactivity (autoimmunity and allergy) of immune system can be deduced to perinatal (hormonal or metabolic) imprinting. The perinatal hormonal (chemical) imprinting takes place at the first encounter between the developing hormone receptor and the target hormone which sets the binding capacity of the receptor for life. In the critical periods of ontogeny (in addition to the perinatal imprinting) it can be developed at weaning, in adolescence and in continuously dividing and differentiating cells during the whole life. It is provoked by considerable quantitative differences of the physiological hormone or the presence of strange target-hormone-like molecules. The faulty hormonal imprinting leads to the adult-age diseases at any time of life and is inherited epigenetically to the progeny generations. Faulty hormonal imprinting always could be present in earlier times however, at present, because of the erroneous multiplication of endocrine disruptors in the environment, nutrition and medicine, its importance is continuously growing. The effects of faulty hormonal imprinting seem to be dangerous however, it can be imagined in the far future also a positive effect by the transformation of the human endocrine system at an evolutionary route. In the metabolic or immunological imprinting as well, as in the DOHaD (Developmental Origins of Health and Disease) the foremost recognized hormonal (chemical) imprinting is materialized.]

[Serum uric acid level in hypertension. Domestic experience based on the data of the Hungarian Hypertonia Register 2011., 2013., 2015. Part I. Introduction. Patients and methods. Basic data]

KÉKES Ede, PAKSY András, ALFÖLDI Sándor

[Worldwide, screening in the general population detects an increase in serum uric acid levels in both sexes. This growth trend is also valid for hypertension. Authors studied the incidence of serum uric acid levels and its correlation with age, risk factors, anthropological, metabolic characteristics, blood pressure, blood pressure target, organ damage, age-related co-morbidity and drug therapy in 47,372 hypertensive patients (22,688 males, 24,684 women). In the first part of their analysis they present the method of analysis and the basic correlations. The uric acid level is higher in men than in women, with the advancement of age increasing. Increases in systolic and diastolic blood pressure are associated with increases in serum uric acid levels, with a tendency for systolic pressure to be significantly higher. For ladies, the rising trend is smaller and always lower in uric acid values. The uric acid value is higher in patients with the non-target blood pressure. The presence of co-morbidity significantly increases serum uric acid levels.]

[Fusions in solid tumors]

KOPPER László

[Genetic fusions are the cosequence of genomic rearrangement including chromosomal inversion, interstitial deletion, duplication, amplifi cation, translocation. Fusions can influence tumor development and progression. Fusions fi rst discovered in hematological malignances (e.g. BCR-ABL), butlater more and more were identified dueto the higly sensitive NGS. It has been found that the oncogenic fusions are in minority in a given tumor. Today, some fusions were apprevedas targets (ALK, ROS1, PDGFB) by FDA. Asino ther targeted therapy resistance is in evitable, which is a very important challenge for newly designed drugs.]

[How can we reach more effective antihypertensive treatment in diabetic patients with hypertension?]

BENCZÚR Béla, TORZSA Péter

[Hypertension is the leading “silent killer” accounting for 10 million deaths worldwide. It frequently occures together with other metabolic risk factors, including type-2 diabetes mellitus and dyslipidemia augmenting the global cardiovascular risk of patients. Their treatment and reaching target blood pressure means a real challenge for practising physicians. According to the recent hypertension guidelines RAAS-inhibitors are the first choice agents which can be excellently combined with diuretics. RAAS-inhibitor based therapy frequently needs to be completed with Ca-antagonist to which statin should be added in the presence of metabolic risk factors. The benefits of amlodipin/atorvastatin fixed combination are multiple: both agents are capable to inhibit the progression of atherosclerosis and to reach blood pressure and LDL target values. In addition the well-known poor statin-adherence can be improved with fixed combination which can contribute to the reduction of risk of these high-risk subjects. ]

L-arginine pathway metabolites can discriminate paroxysmal from permanent atrial fibrillation in acute ischemic stroke

CSÉCSEI Péter, VÁRNAI Réka, NAGY Lajos, KÉKI Sándor, MOLNÁR Tihamér, ILLÉS Zsolt, FARKAS Nelli, SZAPÁRY László

Background - Atrial fibrillation (AF) is the most common arrhythmia diagnosed in clinical practice. We aimed to measure the L-arginine pathway metabolites as well as their ratios in patients with different types of AF or sinus rhythm and to explore the relationship among the markers and clinical variables in the subacute phase of acute ischemic stroke (AIS). Methods - A total of 46 patients with AIS were prospectively enrolled. The patients were divided into three groups based on diagnosis of either sinus rhythm, paroxysmal or permanent AF. Plasma concentration of the L-arginine pathway metabolites were analyzed at post-stroke 24 hours in the three rhythm groups. Besides, clinical variables and laboratory data were recorded. Results - Asymmetric dimetylarginine (ADMA) was significantly higher in patients with permanent AF compared to sinus rhythm (p<0.001). Both ADMA (p<0.001) and symmetric dimethylarginine (SDMA) (p<0.002) at 24 hours were significantly higher among patients with permanent AF compared to those with paroxysmal AF. The L-arginine/SDMA (p<0.031) ratios at 24 hours were significantly higher among patients with sinus rhythm compared to those with permanent AF. ROC analysis also revealed that plasma SDMA cut-off level over 0.639 μmol/L discriminated permanent AF from paroxysmal AF or sinus rhythm with a 90.9% sensitivity and 77.1% specificity. Neutrophil-lymphocyte ratio also showed significantly higher value in individuals with both paroxysmal and permanent AF (p=0.029). Conclusions - Plasma level of SDMA could discriminate permanent from paroxysmal AF in the subacute phase of ischemic stroke. In addition, an increased neutrophil-lymphocyte ratio may suggest inflammatory process in the evolution of atrial fibrillation.

Secretory meningioma with bone infiltration and orbital spreading

KÁLOVITS Ferenc, TAKÁTS Lajos, SOMOGYI Katalin, GARZULY Ferenc, TOMPA Márton, KÁLMÁN Bernadette

Secretory meningioma is a rare form of meningiomas which differentiates from the meningothelial subtype. It is characterized by significant peritumor edema and distinct immunohistochemical and molecular genetic profiles. We present a middle aged female patient with secretory meningioma infiltrating the orbital bone from the primary cranial base location and causing exophthalmos, features rarely described with this tumor. Surgical resection was challenging because of the associated brain swelling and rich vascularization of the tumor. Imaging and immunohistochemical studies revealed characteristic hallmarks of secretory meningioma. While histologically it was a benign tumor, due to the orbital bone and soft tissue infiltration, postoperative management of neurological sequelae was challenging. This case highlights distinctive clinical, imaging and histological features along with individual characteristics of a rare form of meningiomas.

[Hereditary hemorrhagic teleangiectasia (HHT, Osler-Rendu-Weber disease) is an autosomal dominantly inherited disorder caused by the mutation of several possible genes and characterized by malformations of the arteriovenous system in multiple organs. The clinical diagnosis is based on the Curaçao criteria ((1) spontaneous, recurrent epistaxis; (2) teleangiectasias in characteristic sites (lips, oral cavity, nose, fingers); (3) visceral lesions (gastrointestinal, pulmonary, cerebral, spinal); (4) affected first degree relative). The aim of this study is to present the first genetically confirmed Hungarian case of hereditary hemorrhagic teleangiectasia with multiple ischemic strokes. Our 70-year-old woman has been suffering from severe epistaxis since her childhood and presented gastrointestinal bleeding during her adulthood as well. The characteristic skin lesions developed in the 5th decade of life. She was admitted to our department with loss of consciousness and fluctuating speech and swallowing problems. MRI of the brain supplemented with angiography revealed multiple arteriovenous malformations and multiple subacute ischemic lesions. The EEG demonstrated slowing of electric activity in the left frontal lobe. The neuropsychological assessment showed deficits in anterograde memory and executive functions. The diagnostic work-up for other characteristic alterations identified an arteriovenous malformation in the left lung. The genetic analysis demonstrated a heterozygous mutation in the 7th exon of the ENG gene at position 834 resulting in a thymine duplication and an early stop codon by a frame shift. The present case is largely similar to those already described in literature and draws the attention to the importance of multidisciplinary collaboration in the care of HHT patients.]

A rare condition mimicking stroke: Diabetic uremic encephalopathy

TEKESIN Aysel, ERDAL Yuksel, MAHMUTOGLU Soydan Abdullah, HAKYEMEZ Ahmet, EMRE Ufuk

Uremic encephalopathy (UE) is a metabolic disorder associated with acute or chronic renal failure. It is characterized by the acute or subacute onset of reversible neurological symptoms and specific imaging findings. It is uncommon for uremic encephalopathy to be associated with acute bilateral lesions of the basal ganglia in diabetic uremic patients, and this can be seen most often in Asian patients. Here, we report a patient with diabetic uremic encephalopathy and bilateral basal ganglia lesions who developed acute onset dysarthria. The clinical and magnetic resonance brain imaging findings resolved after hemodialysis treatment.

[Physical training in dialysis population]

SCHNEIDER Károly

[The impaired physical activity and the related increased cardiovascular risk is caracteristic in all stages of chronic kidney diseases. The regular physical activity has a beneficial effect on the metabolic risks associated with chronic kidney disease, dialysis and poor activity lifestyle, it also has favorable effect on the inflammatory state, poor physical performance, muscle loss and can improve the quality of life and life expectancy. Accordingly, the international and Hungarian guidelines suggest at least 150 minutes physical activity with moderate intensity per week - at least five days, 30 minutes each day. But there are no particular guidelines for dialysated patients. This article, without being exhaustive, in part using our own experiences, present suggestions for the physical activity of dialysated patients.]

[Hyperuricemia and cardiovascular risk: new treat to target principle in focus]

ALFÖLDI Sándor

[Hyperuricemia is frequent and its prevalence is increasing as it correlates with obesity and metabolic syndrome by several different mechanisms. Furthermore, recently several data are available for the cardiovascular and renal protective effect of allopurinol in the treatment of hyperuricemia and gout. The new European EULAR guidelines suggested treat to target principle in urat lowering therapy of gout. The uric acid target is below 360 µmol/l in mild to moderate gout. The guidelines unequivocally stated, that allopurinol is the first line uric acid lowering drug. Allopurinol treatment should be started immediately at the diagnosis and should be continued lifelong.]
