[Paradigmal changes in renal replacement therapy. Dialysis and drug therapy of quality in chronic renal patients - Optimal and adequate opportunities of dialysis therapy]


[Researches over the past thirty years, many results have been related to acute and chronic renal failure pathophysiology, clinical characteristics and therapy. Can be more than just the uremic toxins and their characteristics of the regulation of salt and water balance, renal anemia treatment, uremic metabolic disorders, calcium phosphate and lipid metabolism dysfunction. Improve the quality of treatment and reduce mortality and options can be influenced by factors come to, therefore, execution and technique of dialysis therapy. We know the primary concern of the treatment period for reducing mortality. This is best for intermittent treatments increased (4.5-6 hours) treatment will help. Narrow scope is optional for the treatment several times a week treatment, the daily 8-hour long nightly therapy. The mortality of the patient significantly influenced by age, gender, co-morbidities, fluid balance and the CaxPO4. The technical side is the key factor influencing the dialysis fluid purity and membrane properties. The use of high-flux membranes is clearly improving the quality of treatment, the additional benefit of hemodiafiltration therapy, the mortality for those still controversial. For optimal dialysis adequacy, complexity may result in reducing mortality and improving the quality of life in chronic dialysis patients.]

[Obstructive sleep apnea, hypertension and cardiovascular risk]


[Obstructive sleep apnea (OSA) is a surprisingly frequent disease worsening the quality of life of the patients, associated with serious complications, however, largely underdiagnosed and undertreated. OSA, hypertension and other symptoms of the metabolic syndrome are closely and independently correlated. OSA has been substantially emphasized as a new (emerging) cardiometabolic risk factor, not only a risk marker. The severe form of OSA (apnea-hypnea index>20/hour) has been accepted as a component of high cardiovascular risk on the Hungarian Cardiovascular Consensus Conference in 2008. Greater attention both to the identification and to the treatment of blood pressure increase associated with OSA as well as to the detection of OSA in patients with the diagnosis of hypertension has been suggested by the new European OSA and Hypertension Position Papers, because hypertension associated with OSA is frequently resistant and the proper management of OSA and hypertension could decrease the cardiovascular risk in patients followed up either in sleep or in hypertension centres.]

[Causes of and therapeutic opportunities in resistant hypertension]

SIMONYI Gábor, GENCSI Kristína

[Hypertension is an independent cardiovascular risk factor and one of the most frequent diseases in Hungary. In the treatment of hypertensive patients usually more than two drugs are needed for the appropriate blood pressure control. Resistant hypertension (RH) is defined when blood pressure remains above target value despite full doses of antihypertensive medications, which consist of at least three different classes of drugs including a diuretic administered in maximal doses. The frequency of RH can reach 20-30% among hypertensive patients. RH increases the cardiovascular risk because of the lack of target blood pressure. RH is multifactorial and it is important to exclude pseudo-resistant hypertension (e.g. poor compliance, white coat effect). In the background of RH we can find lifestyle factors (e.g. obesity, excessive salt intake, alcoholism, etc.) and a variety of drugs (e.g. non-steroids, corticosteroids, sympathomimetics). In the pathogenesis of RH the increased activity of the sympathetic nervous system has an important role. In the treatment of RH we should manage lifestyle factors and it is important to assess the drugs and diseases (e.g. sleep apnea, chronic kidney disease, diabetes mellitus) which may cause increased blood pressure. It is no exact recommendations for the treatment of RH. Therapy often consists of 4-5 various drugs in combination. An important role has the device therapy of RH in recent years (e.g. stimulation of the carotid baroreceptors and renal denervation) as well.]

[The success of fixed combined amlodipine/atorvastatin (Amlator®) therapy in patients with hypertension and dyslipidemia]


[In total 2606 patients with hypertension and dyslipidemia got combined antihypertensive and antilipid-treatment. The main component of therapy was amlodipine/ atorvastatin fixed combination in different dose variations. The goal of the study was to access optimal target blood pressure and lipid profile. The baseline average blood pressure value was 155.9/90.18 mmHg and it decreased to 132.77/80.04 mmHg during the six months therapy. The lipid profile also changed successfully: the average value of total cholesterol decreased from 5.97 mmol/l to 4.68 mmol/l, LDL cholesteron from 3.45 mmol/l to 2.49 mmol/l and serum triglyceride from 2.1 mmol/l to 1.69 mmol/l. We reached the target values in respect of LDL cholesterol (<2.5 mmol/l) and of triglyceride (<1.7 mmol/l) prescribed in guidelines for subjects with high cardiovascular risk. According to the global cardiovascular risk estimation (European Heart Score) the risk ratio in percent was significantly decreased in each age group, in both genders and in smoking or nonsmoking subjects.]

[Population based study of hypertension in Hungary - 2012 Comprehensive Health Protection Screening Program of Hungary 201-2020]

BARNA István, DAIKI Tenno, DANKOVICS Gergely, KÉKES Ede, KISS István

[Background: The year 2011 saw the continuation of Hungary’s greatest and to date most comprehensive health screening programme started in 2010. The aim of the screening programme established according to the directives of the European Union with the cooperation of more than forty professional organisations is the preservation of the health of the population, the prevention of illnesses and the improvement of the general health status. The programme contributes to the prevention of coronary diseases by passing on knowledge concerning healthy nutrition and guidelines to help the establishment of a health-conscious lifestyle. Partecipants and methods: In the Comprehensive Health Tests Programme of Hungary, the examinations, among them coronary examinations covering the fields of cardiology and hypertension, take place in a specially furnished lorry. The results of the examinations of the people who have presented themselves for the tests (n=19,814) have been evaluated. In the Comprehensive Health Tests Programme of Hungary a total of 10,444 (52.7%) women and 9,370 (47.3%) men were tested at 332 locations. Although the tests were free for all adults, predominantly persons between the ages of 26 and 55 presented themselves. The average age of women was 42 years and that of the men was 40 years. Results: Upon data processing with the help of a query, 28% of the participants reported suffering from hypertension disease. Measurement of the blood pressure was carried out in each case with validated equipment and by qualified medical staff. Based on the data, it can be observed that while among men hypertension tends to occur in larger numbers at a younger age, the tendency is reversed at ages above 45 years, where hypertension is more frequent among women. Among women, the state of normotonia was most frequent up to the age of 45 and stage 1 hypertension became most frequent from the age of 46 onwards. It must be noted, however, that stage 3 hypertension was already present in 1.7% of women of 26 years of age, and the frequency of this category increased to 6% from the age of 46 onwards. The average systolic blood pressure measured among men exceeded the upper limit of the normal range for all age groups. The average systolic blood pressure measured among women was in the normal range up to the age of 55 years and only moved to the pathological range from the age of 56 onwards. The diastolic blood pressure levels were in the normal range for both sexes (with the exception of the age group 46-55 of the men, where it exceeded the upper limit of the normal range by a minimal extent). Among the men, stage 1 hypertension was the most frequent status for all age groups; blood pressures above 140/90 were measured for 39% of the subjects from the age of 18 onwards. The distribution of this did not vary significantly with the increase of age. It must be mentioned here too, that stage 3 hypertension became more frequent with age, and that it was observed in more than 11% of the patients above 56 years of age. The correlation between abdominal circumference, total cholesterol, blood sugar level and the measured blood pressure values was unambiguously ascertainable. In case of simultaneous presence of diabetes and hypertension (women, n=344 and men, n=303), blood pressures above 140/90Hgmm were 2-3 times more frequent for both sexes than without the presence of diabetes. Discussion: Thanks to the vast information obtained through the programme, a comprehensive picture has been drawn up about Hungary’s present health status not only on a regional or cross sectional level, but as it was described in the programme, too. ]

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. ]

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.

[Ulcerative carpal tunnel syndrome]


[The carpal tunnel syndrome is the most frequent compression-induced neuropathy. A severe but rare clinical manifestation of this disorder associates with ulceration, acral osteo-lysis and mutilation of the terminal phalanges of the second and third fingers. Recognition of this disorder is difficult, because various dermatological and internal diseases might lead to acral ulcerative lesions, and these patients are seldom referred to neurological and/or electrodiagnostic examination. In this article, we present three cases of this rare clinical form of carpal tunnel syndrome and discuss the electrodiagnostic findings. The early diagnosis is important since decompression of the median nerve in due time might prevent mutilation and could significantly improve the patients’ quality of life.]
