[METABOLIC “X” SYNDROME: “XYNDROME” - POSITIONS AND OPPOSITIONS]

MATOS Lajos

[The idea of a constellation of abnormalities linked to insulin resistance as a key component was pioneered and summarized by Reaven in 1988 under the name of “X” syndrome. Based on the various elements of the syndrome, several synonyms have been proposed, including “deadly trio”, “deadly quartet”, “central fat syndrome”, “insulin resistance syndrome”. To avoid the confusion of this entity with “cardial X syndrome”, an established syndrome in cardiology, and instead of the rather long “metabolic X syndrome”, I have proposed the term “Xyndrome”. Irrespective of how it is called, this syndrome has come into the focus of clinical research; using the keyword “metabolic syndrome” to search in the index of the National Library of Medicine, 15.661 citations pop up, and in February 2006 only, 168 papers were published in this field. In spite of this, several international scientific organizations have recently claimed that metabolic syndrome has not been unambiguously defined, its diagnostic criteria are contradictory, and finally, the syndrome as an entity has no more value in predicting cardiovascular risk than the sum of its individual components has, therefore, the use of this notion in the clinical practice is not recommended. There are, however, opposing opinions emphasizing the importance of abdominal obesity - today considered to be most essential element -, data from recent research, and the didactic advantage that the use of this notion has improved complex treatment of its various components. It is crucial to understand that “syndrome” is not more - and not less, either - than a clustering of symptoms and findings, and should not be treated as a distinct disease. The emergence of the notion of metabolic syndrome, however, has been a step forward in the medical concept in that metabolic and cardiovascular diseases are now dealt with in a more complex way, which warrants the maintenance of this notion and the increase of our understanding by continuing research in this field.]

[THE LONG ACTING INSULIN ANALOGUE DETEMIR IN THE DIABETOLOGICAL PRACTICE: EVIDENCE AND POTENTIALS]

TAMÁS GYULA, KERÉNYI ZSUZSA

[Insulin detemir is a neutral, soluble, long-acting insulin analogue in which the amino acid threonineB30 has been removed and the LysB29 acylated with a 14-carbon fatty acid. The fatty acid modification allows insulin detemir to dihexamerisate and reversibly bind to human albumin upon administration. This brand new principle (self association and albumin binding) ensures slow absorption and a prolonged and consistent metabolic effect without a marked peak for up to 24 hours in patients both with type 1 and type 2 diabetes mellitus. Results of large clinical trials have shown that detemir can be efficiently used as basal insulin, supplemented with human regular insulin or aspart insulin taken before the main meals, in both type 1 and type 2 diabetes. Available data clearly demonstrate that the use of this insulin is associated with decreased variability of the fasting blood glucose values. In some of the studies the risk of (mostly nocturnal) hypoglycaemic episodes also dropped. It is important to note that patients using insulin detemir gained less or no weight compared to the group of patients treated with neutral protamine Hagedorn (NPH) insulin. Evaluation of long-term and wide-spread application of detemir needs further observations. Such trials are being conducted worldwide.]

[SOME FORMS OF SECONDARY OSTEOPOROSIS: DIAGNOSIS AND TREATMENT]

GENTI György, PÉNTEK Márta, LICKER-FÓRIS Edit

[Secondary causes of bone loss are not often considered in patients, who are diagnosed as having osteoporosis. There are many causes of secondary osteoporosis, including endocrine diseases, renal disorders, transplantation, glucocorticoid therapy, inflammatory rheumatic diseases etc. This article gives an overview on the most frequent and in the everyday practice important forms of secondary osteoporosis. The first principle is the correct diagnosis and the adequate treatment of the underlying disease. In the prevention and treatment of secondary bone loss similar principles are followed as in the primary forms. Calcium, Vitamin D, personalized, well-aimed physical therapy and continuous physical activity are the basic treatment of secondary osteoporosis. Active form of Vitamin D, which does not require calcium combination, has to be applied in advanced age, in impaired renal function, and in case of ineffective therapy with cholecalciferol. Evidence based data suggest that bisphosphonates (alendronate and risedronate) are the most effective antiresorptive agents in the prevention and treatment of glucocorticoid- induced osteoporosis and in osteoporosis associated with rheumatoid arthritis. To prevent secondary hyperthyreoidism during bisphosphonate treatment, a calcium intake of 1000 1500 mg/d and an 800 IU/d of cholecalciferol are recommended. Ibandronate (150 mg once a month), a new bisphosphonate will be available soon. Parathyroid hormone (teriparatide) is an anabolic agent, that enhances bone formation. Its recent introduction offers new options in the treatment of patients with established osteoporosis.]

Alexithymia is associated with cognitive impairment in patients with Parkinson’s disease

SENGUL Yildizhan, KOCAK Müge, CORAKCI Zeynep, SENGUL Serdar Hakan, USTUN Ismet

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.

[Avoiding unlimited energy drink consumption is a matter of our heart]

DOJCSÁKNÉ Kiss-Tóth Éva

[Energy drinks have been gaining unbroken popularity, especially among youngsters and children since they were introduced to the market. Manufacturers promise to improve performance and stamina with consuming the products, classified as non-alcoholic soft drinks. In addition to the vitamins and plant extracts, they contain a significant amount of caffeine and other stimulants (taurine, guarana). Among the active ingredients, caffeine has an outstanding effect and thereby a danger, since its overconsumption – in addition to milder he­mo­dynamic changes – can cause severe cardio­vascular consequences, cardiac arrhythmias, ion channel diseases, increased blood coagulation, myocardial infarction or reduced cerebral blood flow in susceptible consumers. Many case studies have also reported serious cardiovascular attacks among young chronic energy drink consumers. Health impairments of excessive and long-term consumption of energy drinks have been studied increasingly, however there is limited and contradictory evidence on the safety of consumption and the effectiveness of performance enhancement. ]

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.

Neurocognitive functions in patients with hepatitis C infection

HORVÁTH Gergely, KELETI Teodóra, MAKARA Mihály, UNGVARI S Gabor, GAZDAG Gábor

Background - With improving treatment options, more attention is being paid to the neurocognitive symptoms related to hepatitis C infection (HCI). While HCI-related neurocognitive impairments are frequently subclinical, they can influence patients’ quality of life and fitness to work. Objective - The aim of this study was to assess HCI patients’ neurocognitive functions and explore the correlations between disease variables and neurocognitive symptoms. Method - The study was conducted between January 1, 2013 and December 31, 2015. All patients with HCI were included in the study who were registered at the Hepatology Outpatient Clinic of Szent István and Szent László Hospitals, met inclusion criteria and volunteered to participate. Patients’ sociodemographic data and medical history were recorded in a questionnaire designed for the study. The 21-item Beck Depression Inventory was used to detect depressive symptoms. Six computerized tests were used to evaluate patients’ neuropsychological functions. Results - Sixty patients participated in the study. In comparison with general population standards, patients demonstrated poorer performance in several neurocognitive tests. Neuropsychological performance was correlated with age, sex, length of time since HCI diagnosis, Fibroscan score and the number of previous antiviral treatments. Conclusions - The study’s main finding is that compared to general population standards, patients with hepatitis C virus-related disease exhibit impaired neuropsychological functioning in visuomotor and visuospatial functions, working memory, executive functions, and reaction time. Executive functions and reaction time were the most sensitive indicators for the length and severity of disease. Deterioration in these functions has a major negative effect on work performance particularly in certain occupations.
