[Proteomics - the new challenge]


[The term ”proteome” (proteome, PROTEin complement to a genOME) by now a generally accepted expression in biomedical science meaning a complete complements of proteins. The discipline ”proteomics”, coined after proteome, deals with the analysis of the complete set of proteins occurring in the living organism. This includes the identification and quantification of proteins, the determination of protein localisation, modifications, interactions, activities and function. Performing comparative studies is an important part of proteomics for the analysis of proteins in health and disease. The knowledge generated is already used for improved diagnostic procedures and development of new drugs and therapies. During the proteome analysis, as outlined in this paper, even very small quantities (concentrations) of proteins are measured, then the protein is identified and its structure is elucidated. This procedure is followed by functional studies. An important part of proteomics is the collection and validation of numerical databases suitable for data mining. There is a general understanding that methodology driven research (e.g. NMR, mass spectrometry, DNA chips) is also an integrated part of this discipline. It is already sensed that the analysis of proteome can lead to the discovery of new proteins proving targets for drug research and to the establishment of new procedures with a perspective of improved diagnosis and therapy.]

[Benefit of combined clopidogrel-aspirin platelet aggregation inhibition in acute coronary syndrome and after percutaneous coronary angioplasty]


[Platelet aggregation inhibition is equally important both in conservative and interventional cardiological treatment of acute coronary syndrome. Recently, results from three important trial were published. All three proved the efficacy of the combined aspirin + clopidogrel treatment. The basic results of the three clinical trials (CURE, PCI-CURE, CREDO) are summarized in the article. In the CURE trial the combined primary endpoint was reached in 11.4% of the patients in the control group and in 9.3% in the clopidogrel group. The relative risk reduction was 20%. The combined primary endpoint included CV mortality, MI and stroke. The treatment effect was mostly detectable in the prevention of MI and stroke. In the PCI-CURE trial 2658 patients of the CURE trial were analysed. All of them were treated by coronary angioplasty. In this group the primary endpoint (CV death, nonfatal MI, urgent revascularisation) was reached in 6.4% of the aspirin treated and in 4.5% of the aspirin + clopidogrel treated patients. The relative risk reduction was 30%. The CREDO trial investigated patients after coronary angioplasty. The indication of angioplasty was either acute or chronic. All patients received combined aspirin + clopidogrel but only for four weeks in the control group or for one year in the treatment group. The combined primary endpoint was decreased by 26.9%. In all the 3 trials the risk of bleeding was slightly but significantly increased by the combined aspirin + clopidogrel treatment. Clinical application: based on the results of the 3 trials it is concluded that combined aspirin + clopidogrel treatment is indicated in all patients with acute coronary syndrome, independently from the treatment strategy. The treatment should be continued for one year. This is also applicable for all patients treated with coronary angioplasty.]

[Extraintestinal manifestations in inflammatory bowel diseases]


[Inflammatory bowel diseases (IBD) are systemic disorders. Bowel symptoms are the predominant manifestations, however during the course of the disease a lot of intestinal and extraintestinal complications may occur. Systemic complications are responsible for substantial co-morbidity and they have negative influence on the quality of life. A part of the extraintestinal symptoms seem to have common pathogenetic background with IBD, while others are the consequences of subsequent metabolic and endocrine abnormalities or may relate to local complications and adverse effects of treatment. Growing evidence is available on the role of genetic and immunologic factors in the pathogenesis of extraintestinal manifestations. Most important systemic complications are: peripheral and axial arthritides, osteoporosis, uveitis, erythema nodosum, pyoderma gangraenosum, primary sclerosing cholangitis, nonalcoholic steatohepatitis, different types of anaemia, thromboembolism, kidney stones and urinary complications. Cooperation with the specialists is very important in the diagnosis and treatment of these comlications. During followup of IBD patients special attention is needed to monitor possible extraintestinal manifestations.]

[Risk of nonsteroidal antiinflammatory drugs. Focus on aceclofenac]


[Nonsteroidal antiinflammatory drugs (NSAIDs) are among the most frequently used pharmaceuticals. Nevertheless, a number of studies emphasized that NSAIDs were damaging not only the gastrointestinal (GI), but also the cardiovascular (CV) system, could increase the blood pressure, the frequency of coronary events (angina, myocardial infarction) and stroke incidence, as well as they might deterio­rate renal functions. The National Institute for Health and Care Excellence (NICE) did not find evidence that administering NSAIDs could increase the risk of developing COVID-19 or worsened the condition of COVID-19 patients. However, unwanted effects of specific drugs differ substantially in their occurrence and seriousness as well. It seemed to be for a long time that the NSAIDs provoked higher GI-risk was closely related to the COX1/COX2 selectivity, like the cardiovascular (CV) risk to the COX2/COX1 selectivity, however, the recent data did not prove it clearly. Based on the available literature while pondering the gastrointestinal and cardiovascular adverse events, among all NSAIDs the aceclofenac profile seemed to be the most favourable.]

The prevalence of sarcopenia and dynapenia according to stage among Alzheimer-type dementia patients

YAZAR Tamer, YAZAR Olgun Hülya

Aim - In this study, the aim was to identify the prevalence of sarcopenia and dynapenia according to disease stage among Alzheimer-type dementia (AD) patients and collect data to suggest precautions related to reducing the disease load. Method - The study was completed with 127 patients separated into stages according to Clinical Dementia Rating Scale (CDR) criteria and 279 healthy volunteers aged 18-39 years and 70-80 years abiding by the exclusion criteria who agreed to participate in the research. Our prospective and cross-sectional study applied the CDR and mini mental test (MMSE) to patients with disorder in more than one cognitive area and possible AD diagnosis according to NINCDS-ADRDA (National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer’s Disease and Related Disorders Association) diagnostic criteria. The patient and control groups had skeletal muscle mass index (SMMI), muscle strength and physical performance assessed with sarcopenia diagnosis according to European Working Group on Sarcopenia in Older People (EWGSOP) diagnostic criteria. Results - In our study, in parallel with the increase in disease stage of AD patients, the prevalence of sarcopenia (led by severe sarcopenia) and dynapenia was higher compared to a control group of similar age. Conclusion - In chronic, progressive diseases, like AD, identification of changes in parameters, like muscle mass and strength and reductions in physical performance in the early period, is important for identification and to take precautions in the initial stages considering the limitations of the preventive effects of treatment applied after diagnosis of AD.

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.

[Education and psychological support of parents in cases of postnatally detected Down syndrome]

MÁTÉ Orsolya, KÍVÉS Zsuzsanna, OLÁH András, FULLÉR Noémi, PAKAI Annamária

[OBJECTIVE - Since the 60’s several publications dealt with the phenomenon how physicians inform parents of newborns about postnatal recognition of Down’s syndrome and the support they receive right after breaking the bad news. Howe - ver, the rest of these studies concentrated on surveying parental satisfaction, while relatively few international studies deal with the other side of the communicational situation, the opinion of the informer. Our study focused on the circumstances of parental information in Hungarian institutions of obstetrics in order to evaluate the possibilities for interventions. METHODS - The Down’s team operating at the University of Pécs Faculty of Health Sciences carried out a national survey in 2005 - an interview-based questionnaire filled by physicians of institutions of obstetrics - with the help of the National Register for Congenital Diseases of the National Centre for Epidemiology and Down’s Foun dation. RESULTS - The coverage of the survey reached 74%. Rest of the surveyed institutions did not have information protocol, however, 70% of them believes it would be necessary. Only 44% of the physicians received communication training and 81% of them believe they can manage communication, 33% have felt that the mother of a newborn with Down’s syndrome would expect special help that the institutions are unable to provide. CONCLUSION - There are serious problems with the circumstances of parental informing in Hungarian institutions of obstetrics. This situation would obviously require intervention. An aimed communicational training based on international experience and exploiting the openness of physicians, as well as the establishment of information protocol could be elements of such intervention.]

GÖKCAL Elif, SENGUL Yildizhan, USLU Ilgen Ferda

Aim - In this study, we aimed to examine the risk factors, topographic features and stroke mechanisms of acute ischemic unilateral infarcts of thalamus. Methods - Patient with isolated thalamic infarct and those with posterior cerebral artery (PCA) infarction who were admitted to our hospital between January 2014 and January 2017 with acute unilateral thalamic infarction (TI) were included in this study (isolated thalamic infarction/ isolated TI; thalamic and posterior cerebral artery infarction/PCA+TI). Demographic characteristics and vascular risk factors of the patients were determined. Thalamic infarct areas were recorded topographically as anterior, posteromedial, ventrolateral, posterolateral, more than one area, and variant areas. Stroke mechanism was determined according to the criteria of „Trial of Org 10172 in Acute Stroke Treatment” (TOAST). Patients with isolated TI and PCA TI were compared according to risk factors, stroke mechanism and infarct topography. Results - Forty-three patients with a mean age of 63.3 ± 14.5 years were included in the study. Twenty-eight patients (60.1%) were found to have isolated TI and the remaining 15 patients (34.9%) had PCA+TI. 32.1% of patients with isolated TI had sensory symptoms on presentation, and 60% of patients with PCA-TI had sensorimotor symptoms. The mean age, the mean score on National Institutes of Health Stroke Scale (NIHSS) and the mean frequency of atrial fibrillation were higher in PCA+TI patients than in isolated-TI patients (p: 0.04, p: 0.004, p: 0.02 respectively). 32.6% of the patients had ventrolateral, 30.2% had posteromedial involvement. Ventrolateral topography was seen in 46.7% of the PCA+TI patients, while posteromedial topography was seen in 39.3% of the isolated-TI patients. 53.6% of the isolated-TI had small vessel disease etiology, while 40% of the PCA+TI had cardioembolic etiology, and the other 40% had large artery atherosclerosis. Conclusion - Our study showed that the most ommon stroke mechanism in patients with thalamic infarction is the small vessel disease. Isolated TI and PCA+TI patients differ in terms of etiologic mechanism and infarct topography. Variant territorial involvement and multiple area involvements can be quite common in thalamic infarcts.
