[Blood pressures of adolescents at screening program in Budapest]

KORMOS-TASI Judit, GÁCSI Erika, SCHEURING Noémi, TÓTH Fanni, CZINNER Antal, SZABÓ László

[The Aim of the screening program was to investigate the blood pressure and the association with obesity, hypercholesterinaemia and increased body fluid in adolescents. Methods: A screening program was conducted during the period from April 2010 to May 2011.The screenings consisted of: blood pressure, heart rate, body composition determination, cholesterol, blood glucose, weight, height and BMI. Results: 2226 children fullfied all of the outlined criteria. Their range of age was between 14–18 years. The average systolic blood pressure was 126.34±12.55 Hgmm volt. At boys were higher 131.87±13.59 then at girls 117.49±5.69 Hgmm. The average diastolic blood pressure was 71.86±8.74 Hgmm. There were also higher at boys 72.61±9.17 then at girls 66.69±5.04 Hgmm. High systolic blood pressure (95%<) were 307/1326 cases at girls, and 403/876 cases at boys. High diastolic blood pressure were together with high systolic blood pressure, but less frequency. High diastolic blood pressure occurred at 85 girls and at 90 boys. Overweight and obes were 18.994% of girls and 15.26% of boys. The percentage of pathological high blood pressure was most frequent among boys and girls who are in the overweight group. The pathologically high level of body fat percentage appeared to be 12.98% among girls and 5.9% among boys. In elevated BMI groups the frequency of high body fat was 66% among girls and 81% among boys. The mean cholesterol was significantly higher in the overweight and obese group. Conclusions: Rates of hypertension and overweight and obesity are high in school children in Budapest, and increased bodyweight is a significant risk factor for hypertension. The results of the study will help to design preventive programmers.]

[Plasma ortho-tyrosine/para-tyrosine ratio predicts hyporesponsiveness to erythropoiesis-stimulating agents in dialyzed patients]

KUN Szilárd, MIKOLÁS Esztella, MOLNÁR Gergő Attila, SÉLLEY Eszter, LACZY Boglárka, CSIKY Botond, KOVÁCS Tibor, WITTMANN István

[Objectives: Patients suffering from end-stage renal failure (ESRF) are mostly treated with erythropoiesis-stimulating agents (ESAs). They often show hyporesponsiveness to ESA, which condition is associated with elevated production of free radicals. Phenylalnine (Phe) is converted into para- and ortho-tyrosine (p- and o- Tyr) by hydroxyl free radical. o-Tyr is produced exclusively in this way. However, physiological isomer p-Tyr is formed in significantly higher amounts by phenylalaninehydroxylase, mainly in the kidney. It has been shown that p-Tyr production is decreased in ESRF. As a result, p-Tyr can be replaced by o-Tyr in proteins, e.g. in proteins playing part in signal transduction of erythropoietin. We aimed to study the association of different Tyr isoforms with ESA-responsiveness. Methods: Four groups of volunteers were involved in our cross-sectional study: healthy volunteers (CONTR; n=16), patients on hemodialysis without ESA-treatment (non-ESA-HD; n=8), hemodialyzed patients with ESA-treatment (ESA-HD; n=40) and patients on continuous peritoneal dialysis (CAPD; n=21). Plasma p-, o-Tyr and Phe levels were detected using a high performance liquid chromatography (HPLC)-method, with fluorescence detection. ESA-demand was expressed as ESA-dose, ESAdose/ body weight and erythropoietin resistance index1 (ERI1, weekly ESA-dose/body weight/hemoglobin). Multivariate regression models were used to examine predictors of ESA-demand. In these models, most of the known predictors of ESA-hyporesponsiveness were included. Results: Lower p-Tyr levels were found in dialyzed patients compared with control subjects. In contrast, o-Tyr levels and o-Tyr/p-Tyr ratios were higher in dialyzed patients. Regarding dialyzed patients, o-Tyr level and o-Tyr/p-Tyr ratio were higher in ESA-HD than in non-ESA-HD and CAPD groups. Weekly ESA-dose/body weight and ERI1 correlated with o-Tyr/p-Tyr ratio (r=0.441, p=0.001; r=0.434, p=0.001, respectively). Finally, o-Tyr/p-Tyr ratio proved to be an independent predictor of ERI1 (β=0.330, p=0.016). Discussion: Our results suggest that elevation of o-Tyr/p-Tyr ratio could be responsible for ESA-hyporesponsiveness in dialyzed patients.]

[Initiation of antihipertensive therapy with fix combinations, focusing on perindopril, amlodipine and indapamide]

FARSANG Csaba

[Early clinical studies proved that most hypertensive patients (>70%) need drug combinations to reach the target blood pressure. We should combine two or three - sometimes more - drugs from different antihypertensive classes for quicker normalisation of blood pressure and to reduce incidence and severity of hypertensive complications. Several international and Hungarian (MHT 2015) guidelines emphasize the advantages of fix combinations against free combinations. Most frequently used combinations contain ACEi + calcium antagonist, or ACEi + diuretic. From them I will focus on the perindopril + amlodipine or perindopril + indapamide combinations. If we do not reach target blood pressure, triple fix combinations (e.g. perindopril + amlodipine + indapamide) can also be used. Now there are fix combinations of different strengths, therefore we may start the therapy with these fix combinations according to patients’ characteristics (e.g. age, complications, concomitant diseases).]

[Rilmenidin - a versatile combination partner in the treatment of high blood pressure]

KÉKES Ede

[The rilmenidin as an imidazoline agonist drug strongly decreases the central sympathetic activity, release of renine and the RAS activity. Because of these advantageous properties the peripheral vascular resistance falls and the blood pressure is decreased. Today it is excellent tool for combination therapy. Useful especially in stress induced hypertension. The antihypertensive effects of ACE inhibitors sor calcium antagonists are increased by rilmenidine. This drug decreases the insuline resistance, it has a positive effect on the carbohydrate and fat metabolism, because it is useful as a complementary therapy in metabolic syndrome and diabetes mellitus of type II. It is useful in stress induced hypertension, and in menopause as well.]

Life threatening rare lymphomas presenting as longitudinally extensive transverse myelitis: a diagnostic challenge

TOLVAJ Balázs, HAHN Katalin, NAGY Zsuzsanna, VADVÁRI Árpád, CSOMOR Judit, GELPI Ellen, ILLÉS Zsolt, GARZULY Ferenc

Background and aims – Description of two cases of rare intravascular large B-cell lymphoma and secondary T-cell lymphoma diagnosed postmortem, that manifested clinically as longitudinally extensive transverse myelitis (LETM). We discuss causes of diagnostic difficulties, deceptive radiological and histological investigations, and outline diagnostic procedures based on our and previously reported cases. Case reports – Our first case, a 48-year-old female was admitted to the neurological department due to paraparesis. MRI suggested LETM, but the treatments were ineffective. She died after four weeks because of pneumonia and untreatable polyserositis. Pathological examination revealed intravascular large B-cell lymphoma (IVL). Our second case, a 61-year-old man presented with headache and paraparesis. MRI showed small bitemporal lesions and lesions suggesting LETM. Diagnostic investigations were unsuccessful, including tests for possible lymphoma (CSF flow cytometry and muscle biopsy for suspected IVL). Chest CT showed focal inflammation in a small area of the lung, and adrenal adenoma. Brain biopsy sample from the affected temporal area suggested T-cell mediated lymphocytic (paraneoplastic or viral) meningoencephalitis and excluded diffuse large B-cell lymphoma. The symptoms worsened, and the patient died in the sixth week of disease. The pathological examination of the presumed adenoma in the adrenal gland, the pancreatic tail and the lung lesions revealed peripheral T-cell lymphoma, as did the brain and spinal cord lesions. Even at histological examination, the T-cell lymphoma had the misleading appearance of inflammatory condition as did the MRI. Conclusion – Lymphoma can manifest as LETM. In cases of etiologically unclear atypical LETM in patients older than 40 years, a random skin biopsy (with subcutaneous adipose tissue) from the thigh and from the abdomen is strongly recommended as soon as possible. This may detect IVL and provide the possibility of prompt chemotherapy. In case of suspicion of lymphoma, parallel examination of the CSF by flow cytometry is also recommended. If skin biopsy is negative but lymphoma suspicion remains high, biopsy from other sites (bone marrow, lymph nodes or adrenal gland lesion) or from a simultaneously existing cerebral lesion is suggested, to exclude or prove diffuse large B-cell lymphoma, IVL, or a rare T-cell lymphoma.

[Family planning in multiple sclerosis: conception, pregnancy, breastfeeding]

RÓZSA Csilla

[Family planning is an exceptionally important question in multiple sclerosis, as women of childbearing age are the ones most often affected. Although it is proven that pregnancy does not worsen the long-term prognosis of relapsing-remitting multiple sclerosis, many patients are still doubtful about having children. This question is further complicated by the fact that patients – and often even doctors – are not sufficiently informed about how the ever-increasing number of available disease-modifying treatments affect pregnancies. Breastfeeding is an even less clear topic. Patients usually look to their neurologists first for answers concerning these matters. It falls to the neurologist to rationally evaluate the risks and benefits of contraception, pregnancy, assisted reproduction, childbirth, breastfeeding and disease modifying treatments, to inform patients about these, and then together come to a decision about the best possible therapeutic approach, taking the patients’ individual family plans into consideration. Here we present a review of relevant literature adhering to international guidelines on the topics of conception, pregnancy and breastfeeding, with a special focus on the applicability of approved disease modifying treatments during pregnancy and breastfeeding. The goal of this article is to provide clinicians involved in the care of MS patients with up-to-date information that they can utilize in their day-to-day clinical practice. ]

[Organic and non-organic perspectives in feeding and eating disorders under three years of age]

SCHEURING Noémi, DANIS Ildikó, KAROLINY Anna, SZABÓ László

[Providing optimal nutrition to infants and toddlers is a critical issue for both parents and experts. Besides the quality and quantity of food, indications of feeding behaviour such as feeding method and acceptance by the child are also crucial when determining feeding issues. The development of self-feeding is a significant part of the healthy somatomental development of a toddler between the age of 0-3 years. Efficient treatment of infants and toddlers with feeding disorders is often challenging in clinical practice. These symptoms frequently appear together with additional behaviour disorders, therefore functional reasons have to be taken into consideration in such cases. Due to the complexity of manifestations, applying tools beyond me­dical competence and involvement of special related professions are necessary. The general diagnostic systems of BNO-10 (International Classification of Diseases) and DSM-V (Statistical Manual of Mental Disorders) which are also applied in our country cannot be used appropriately for clear classification of early childhood feeding disorders and for examination of their backgrounds. DC:0-3R (Diagnostic Classi­fication of Mental Health and Develop­men­tal Disorders of Infancy and Early Childhood- Zero to Three), generally used in Anglo-Saxon countries, can be considered as a complex diagnostic system. Using the DC:0-3R classification system (1), we will present six types of feeding disorders affecting children between the age of 0-36 months in which organic and functional origins have been examined as well. In our article we argue for the complex, psychosomatic interpretation and treatments of early childhood feeding disorders.]

CANOMAD syndrome with respiratory failure

SALAMON András, DÉZSI Lívia, RADICS Bence, VARGA Tímea Edina, HORTOBÁGYI Tibor, TÖMÖSVÁRI Adrienn, VÉCSEI László, KLIVÉNYI Péter, RAJDA Cecília

CANOMAD (chronic ataxic neuropathy, ophthalmoplegia, M-protein agglutination, disialosyl antibodies) syndrome is a rare polyneuropathy. IgM paraproteins react with ganglioside-containing disialylated epitopes resulting in dorsal root ganglionopathy and B-lymphocyte infiltration of cranial and peripheral nerves. Clinical features include ataxia, slight muscle weakness, areflexia, sensory- and cranial nerve symptoms. Case studies have reported the efficacy of rituximab and intravenous immunoglobulin (IVIg) treatments. We present the case of a 57-year-old man, who had difficulty walking, with numbness and clumsiness in all limbs. He had areflexia, vibratory sensation loss and ataxia. Laboratory tests showed IgM monoclonal components and disialosyl antibodies in the serum. Nerve conduction studies indicated severe sensorimotor demyelinating polyneuroradiculopathy. Despite IVIg and rituximab treatments, the patient’s disease course gradually worsened and he died of respiratory failure. Neuropathological examination revealed dorsal column- and dorsal root atrophy with mixed mononuclear cell infiltration. This article aims to draw attention to this syndrome, and the use of early potent immunosuppressive treatment to improve patients’ quality of life.
