[Autoimmun thyroiditis presence in patient with Hodgkin’s disease in remission]

BÍRÓ Edit, BAKÓ Gyula, SZEGEDI Gyula, ILLÉS Árpád

[INTRODUCTION - It is known that the incidence of hypothyroidism is higher in long term survivor patients with Hodgkin's disease, and it is supposed to be the result of treatment, such as neck radiotherapy. The author believe that other etiologic factors may also play a role in the development of hypothyroidism. PATIENTS AND METHODS - Looking for the possible causes of hypothyroidism, the thyroid function of 151 patients treated for Hodgkin's disease since 1970 were examined. These patients with Hodgkin's disease in complete remission for at least one year and their data on thyroid autoantibody positivity [antithyroid peroxidase antibody (aTPO), antihuman thyroglobulin antibody (aHTG), TSH antireceptor antibody (TRAK)] were analysed. RESULTS - Among the patients with antibody positive 26 received ultrasound scanning and fine needle aspiration cytology of the thyroid, which confirmed autoimmun thyroiditis. There were no significant differences between the mean age, histologic subtypes and stage of the disease between the patients with antibody positive those with antibody negative. A significantly greater number of women in the group of antibody positive patients was found and thyroid dysfunction (two cases of hyper, and 13 cases of hyperthyroidism) was revealed in 53.6% of the patients. Though antibody positivity was more frequent in patients having been treated by neck irradiation, but no significant relationship was found between the form of Hodgkin’s disease treatment and the development of thyroiditis. Thus the authors cannot confirm the assumption according to which the autoantigens released from the thyroid gland damaged by neck irradiation for Hodgkin's disease would provoke the development of thyroiditis. Since - independently of the type of treatment received - the incidence of thyroiditis is higher in patients with Hodgkin's disease, it is probable that immune regulation disorders may also play a role in its development and thus hypothyroidism is the result of a multi-factor process. DISCUSSION - These results underline the importance of a regular control of thyroid hormones and thyroid autoantibodies in follow up Hodgkin’s disease patients. Levothyroxine administered as an isohormone treatment may inhibit the development of hypothyroidism in patients with thyroiditis may improve the quality of their life.]

[Changes in the signal transduction of T-lymphocytes caused by hyperglycemia]

BOLDIZSÁR Ferenc, BERKI Tímea, MISETA Attila, NÉMETH Péter

[AIMS - Lately the altered calcium balance of different cell types (eg.: erythrocytes, platelets, neutrophil granulocytes) was described in diabetes mellitus. It is also known that patients with diabetes mellitus suffer from various infections more often then healthy individuals because of immunological malfunctions. But the mechanism of these changes is still unclear. In order to investigate the effect of hyperglycemia on the function of immunocompetent cells we established an in vitro diabetes model by culturing human T cells (Jurkat cells) at different glucose concentrations for one week. Then we measured the basal cytosolic calcium level, the calcium signal after ionomycin or anti-CD3 treatment and the tyrosinephosphorylation of signal transducing proteins as well as the fructosamine level of cellular proteins. MATERIALS AND METHOD - Cytosolic free calcium levels were detected by flow cytometry using ion selective fluorescent indicator (Fluo-3 AM). Calcium signals of Jurkat cells were measured after ionomycin or monoclonal anti-CD3 antibody (OKT3) treatment. We also measured the tyrosine-phosphorylation on flow cytometer after anti-CD3 stimulation using indirect immunfluorescent labeling with monoclonal antiphospho- tyrosine antibody. The non-enzymatic glycation of cellular proteins was determined by measuring the fructosamine levels of cell lysates. RESULTS - The higher concentration of extracellular glucose resulted in concentration-dependent elevation of basal cytosolic free calcium level in Jurkat cells. Reduced calcium signal (activation capacity) was measured either after ionomycin or monoclonal anti-CD3 antibody treatments in cells kept at hyperglycemic conditions. In addition, the time kinetics of calcium signal following anti- CD3 activation was found prolonged in the hyperglycemic cells. The tyrosine-phosphorilation of hyperglycemic Jurkat cells also proved to be impaired. High glucose concentrations in tissue culture medium caused increase in the glycation of T-cell proteins. CONCLUSIONS - We propose that increased glycation of proteins involved in calcium transport and/or intracellular signal transduction of T-cells may account for our observations.]

[Ocular myositis]

KISS Emese, FACSKÓ Andrea, DÉVÉNYI Katalin, DANKÓ Katalin, ZEHER Margit

[INTRODUCTION - Dermato-/polymyositis is an autoimmune disorder, which belongs to the idiopathic inflammatory myopaties. It involves skeletal muscles in form of weakness and inflammatory infiltrates. Characteristic skin lesions are present in dermatomyositis. Other organs may also be affected mainly in the presence of myositis specific autoantibodies. The inflammation usually involves the proximal muscles of extremities. CASE REPORT - In the present work we report the case of a 52-year-old woman. In the previous history the removal of rectal adenocarcinoma was remarkable in 1994. After that she received chemotherapy. She complied for severe headache and pain in the right eye in 2000 October, therefore a skull CT was performed, indicating thickening of rectus medalis muscle within orbital cavity. There was an enhancement of contrast material in the muscle. Glaucoma was excluded. Neurologist suspected the presence of myositis and indicated 0.5 mg/kg corticosteroid therapy. Soon after the left eye became painful, but due to the corticosteroid treatment both eyes became painless. A control orbital CT was completely negative in 2000 November. Immunology consultancy revealed a mild proximal muscle atrophy in both lower extremities, but CPK and LDH enzyme levels were normal, EMG was characteristic for mild chronic nerve lesion. The biopsy, taken from the involved proximal muscle of lower extremity, did not show inflammatory infiltration. Complete screening for cancer was negative. Thyroid gland disease could be excluded. Immune laboratory data were negative, autoantibodies, including anti-Jo1, could not be detected. Based on the results a rare disease, ocular myositis was diagnosed. Considering the clinical improvement, the withdrawal of corticosteroid therapy was offered. Stringent immunology and oncology follow-up is required. CONCLUSION - In relation to our case report, we discuss clinical symptoms of orbital myositis, diagnostic procedures to identify the disease and also differential diagnostic considerations.]

[Anti-synthatase syndrome]

PONYI Andrea, CONSTANTIN Tamás, DANKÓ Katalin

[The idiopathic inflammatory myopathies (IIM) are autoimmune diseases, characterized by symmetric proximal muscle weakness. Over the last several decades, many abnormalities of the cellular and humaral immune systems of IIM patients have been described. Some of these are autoantibodies unique to the IIM (the myositis specific autoantibodies MSA). The MSAs are antigen-driven, arise months prior to the onset of myositis, correlate in titre with disease-activity. Studies in the recent years proved that clinically and immuno-geneticaly different disease entities can be defined using myositis specific auto-antibodies. Their use make the serological classification. Myositis specific autoantibodies make it possible to define more homologies subgroups within polymyositis/dermatomyositis that may support the adequate treatment. The most common MSA is the antihistidyl- transfer RNA synthetase (anti-Jo-1), which can be found in 5-30% of patients with myositis. Patients with anti-synthatase antibodies tend to have characteristic clinical presentation of fever, small joint arthritis, intestinal lung disease, Raynaud's phenomenon, mechanic's hands and severe myositis. Sera of 65 PM/DM were tested for anti-Jo- 1 antibody. 15 patients (23%) had anti-Jo-1 antibody (10 PM, 5 DM). The patients with anti-Jo- 1 antibody has a significantly higher incidence of interstitial lung disease, arthritis, fever and Raynaud's phenomenon. These patients needed not only corticosteoid therapy, but other immunosupressive treatment. All 15 patients presented with the onset of weakness between February and July. The determination of myositis-specific autoantibodies has produced more homogenous grouping within the polymyositis/dermatomyositis patients.]

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]

[The connection between the socioeconomic status and stroke in Budapest]

VASTAGH Ildikó, SZŐCS Ildikó, OBERFRANK Ferenc, AJTAY András, BERECZKI Dániel

[The well-known gap bet­ween stroke mortality of Eastern and Western Euro­pean countries may reflect the effect of socioeconomic diffe­rences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomi­cally deprived neighborhoods. ]

[The Comprehensive Aphasia Test in Hungarian]

ZAKARIÁS Lilla, RÓZSA Sándor, LUKÁCS Ágnes

[In this paper we present the Comprehensive Aphasia Test-Hungarian (CAT-H; Zakariás and Lukács, in preparation), an assessment tool newly adapted to Hungarian, currently under standardisation. The test is suitable for the assessment of an acquired language disorder, post-stroke aphasia. The aims of this paper are to present 1) the main characteristics of the test, its areas of application, and the process of the Hungarian adaptation and standardisation, 2) the first results from a sample of Hungarian people with aphasia and healthy controls. Ninety-nine people with aphasia, mostly with unilateral, left hemisphere stroke, and 19 neurologically intact control participants were administered the CAT-H. In addition, we developed a questionnaire assessing demographic and clinical information. The CAT-H consists of two parts, a Cognitive Screening Test and a Language Test. People with aphasia performed significantly worse than the control group in all language and almost all cognitive subtests of the CAT-H. Consistent with our expectations, the control group performed close to ceiling in all subtests, whereas people with aphasia exhibited great individual variability both in the language and the cognitive subtests. In addition, we found that age, time post-onset, and type of stroke were associated with cognitive and linguistic abilities measured by the CAT-H. Our results and our experiences clearly show that the CAT-H provides a comprehensive profile of a person’s impaired and intact language abilities and can be used to monitor language recovery as well as to screen for basic cognitive deficits in aphasia. We hope that the CAT-H will be a unique resource for rehabilitation professionals and aphasia researchers in aphasia assessment and diagnostics in Hungary. ]

[Thiazide- or thiazide-like diuretics should be used in the treatment of patients with hypertension? Particularities of the situation in Hungary]

VÁLYI Péter

[Diuretics have remained the cornerstone of the antihypertensive treatment since their widespreading in the 1960s. According to the 2018 ESC/ESH Guidelines for the management of arterial hypertension, in the absence of evidence from direct comparator trials and recognizing that many of the approved single-pill combinations are based on hydrochlorothiazide, this drug and thiazide-like indapamide can be considered suitable antihypertensive agents. In the 2018 Hungarian guidelines indapamide is named as the most efficacious diuretic in the treatment of patients with hypertension. The aim of the publication is redefining thiazide- and thiazide-like diuretic use in the treatment of hypertensive patients, with particular attention to presently available hydrochlorothia­zide and indapamide, and their combination drugs in Hungary.]

[Focus on Lege Artis Medicinae (LAM)]

VASAS Lívia, GEGES József

[Three decades ago, LAM was launched with the goal of providing scientific information about medicine and its frontiers. From the very beginning, LAM has also concerned a special subject area while connecting medicine with the world of art. In the palette of medical articles, it remained a special feature to this day. The analysis of the history of LAM to date was performed using internationally accepted publication guidelines and scientific databases as a pledge of objectivity. We examined the practice of LAM if it meets the main criteria, the professional expectations of our days, when publishing contents of the traditional printed edition and its electronic version. We explored the visibility of articles in the largest bibliographic and scientific metric databases, and reviewed the LAM's place among the Hun­ga­rian professional journals. Our results show that in recent years LAM has gained international reputation des­pite publishing in Hungarian spoken by a few people. This is due to articles with foreign co-authors as well as references to LAM in articles written exclusively by foreign researchers. The journal is of course full readable in the Hungarian bibliographic databases, and its popularity is among the leading ones. The great virtue of the journal is the wide spectrum of the authors' affiliation, with which they cover almost completely the Hungarian health care institutional sys­tem. The special feature of its columns is enhanced by the publication of writings on art, which may increase Hungarian and foreign interest like that of medical articles.]
