[Non-invasive evaluation of cardiovascular risk in pediatric chronic kidney disease patients]

BÁRCZI Adrienn, DÉGI Arianna Amália, KIS Éva, REUSZ György

[Cardiovascular diseases are the leading cause of mortality and morbidity in children with chronic kidney disease (CKD). Similar to adults, children with CKD experience a high burden of traditional and uremia-associated risk factors. Recent years, several studies were published in connection with cardiovascular risk factors, patomechanism, and early markers of cardiovascular diseases. Early signs of cardiomyopathy, such as left ventricular hypertrophy or dysfunction, and markers of atherosclerosis, such as increased intima-media thickness of the carotid artery or increased wall stiffness of the aorta are frequently present in early stages of CKD in children. As prevention is important in pediatrics, the evaluation of subtle changes of the cardiovascular system provide opportunity for early treatment and that enables children to develop normally and have a better long-term quality of life. Recently, newer non-invasive cardiovascular imaging modalities have been emerged to diagnose subclinical alterations of the heart and vessels in this specific population with kidney disease. In this review, we provide an overwiev of the emerging imaging techniques used to detect early subclinical organ damage in pediatric chronic kidney disease patients.]

Modern health worries in patients with affective disorders. A pilot study

FREYLER Anett, SIMOR Péter, SZEMERSZKY Renáta, SZABOLCS Zsuzsanna, KÖTELES Ferenc

Background - Modern health worries (MHWs) are asso­ciated with various indicators of negative affect, conspiracy theories, and paranormal beliefs in healthy individuals. Purpose - The current pilot study aimed to assess MHWs and indicators of negative affect in patients with affective disorders (N = 66), as well as the possible associations between MHWs and paranoid and schizophrenic tendencies. Results - Compared to somatic patients, psychiatric patients showed higher levels of MHWs, somatosensory amplification, health anxiety, and somatic symptoms. Medium level associations between MHWs and paranoid (r = 0.35, p < 0.01) and schizophrenic (r = 0.37, p < 0.01) tendencies were also revealed. Somatosensory amplification (β = 0.452, p < 0.001) and paranoia (β = 0.281, p < 0.01) significantly contributed to MHWs in multiple linear regression analysis (R2 = 0.323, p < 0.001). Discussion - High (i.e. pathological) levels of negative affect can impact a number of related characteristics. Non-pathological paranoid tendencies might contribute to MHWs. The identification of paranoid tendencies seems to be relevant for the treatment of psychiatric patients exhibiting MHWs. Conclusion - Patients with affective disorders are characterized by higher levels of modern health worries, health anxiety, and somatosensory amplification. Modern health worries are associated with paranoid tendencies.

[Experimental models of renal fibrosis]

KÖKÉNY Gábor

[The high incidence of chronic kidney diseases and, regardless of the etiology, their progression to renal fibrosis with end-stage renal failure rise the urgent need to reveal the pathomechanisms. As the disease leads to complex changes in the body, it is essential to use in vivo model systems for these investigations. Animal experiments choosing the appropriate model system helps to develop more sensitive early diagnostic markers and new therapeutic approaches. Several animal experimental model descriptions can be found in the literature, which mimic specific or more general human diseases in order to help the better understanding of the pathomechanisms. Using these model systems, we are able to analyze the detailed pathophysiology of glomerulonephritis, tubulointerstitial fibrosis, glomerular scarring or generalized renal fibrosis. The most commonly used model systems for renal fibrosis are presented and discussed.]

Somatosensory amplification absorption contribute to electrosensitivity

KÖTELES Ferenc, SIMOR Péter, SZEMERSZKY Renáta

Background - Two trait-like characteristics, somatosensory amplification and absorption, have been associated with symptom reports and idiopathic environmental intolerances in past research. Purpose - As the two constructs are not connected with each other, their independent contribution to symptom reports and electromagnetic hypersensitivity, as well as their interaction can be expected. Methods - On-line questionnaire. Patients - 506 college students completed an on-line questionnaire assessing absorption, somatosensory amplification, negative affect, somatic symptoms, and electromagnetic hypersensitivity. Results - Somatosensory amplification (β = 0.170, p < 0.001) and absorption (β = 0.128, p < 0.001) independently contributed to somatic symptoms after controlling for gender and negative affect (R2 = 0.347, p < 0.001). Similarly, somatosensory amplification (OR = 1.082, p < 0.05) and absorption (OR = 1.079, p < 0.01) independently contributed to electromagnetic hypersensitivity after controlling for somatic symptoms, gender, and negative affect (Nagelkerke R2 = 0.134, p < 0.001). However, no interaction effects were found. Discussion - Somatosensory amplification and absorption independently contribute to symptom reports and electromagnetic hypersensitivity. Conclusion - The findings suggest that psychological mechanisms underlying symptom reports and electromagnetic hypersensitivity might be heterogeneous.

L-arginine pathway metabolites can discriminate paroxysmal from permanent atrial fibrillation in acute ischemic stroke

CSÉCSEI Péter, VÁRNAI Réka, NAGY Lajos, KÉKI Sándor, MOLNÁR Tihamér, ILLÉS Zsolt, FARKAS Nelli, SZAPÁRY László

Background - Atrial fibrillation (AF) is the most common arrhythmia diagnosed in clinical practice. We aimed to measure the L-arginine pathway metabolites as well as their ratios in patients with different types of AF or sinus rhythm and to explore the relationship among the markers and clinical variables in the subacute phase of acute ischemic stroke (AIS). Methods - A total of 46 patients with AIS were prospectively enrolled. The patients were divided into three groups based on diagnosis of either sinus rhythm, paroxysmal or permanent AF. Plasma concentration of the L-arginine pathway metabolites were analyzed at post-stroke 24 hours in the three rhythm groups. Besides, clinical variables and laboratory data were recorded. Results - Asymmetric dimetylarginine (ADMA) was significantly higher in patients with permanent AF compared to sinus rhythm (p<0.001). Both ADMA (p<0.001) and symmetric dimethylarginine (SDMA) (p<0.002) at 24 hours were significantly higher among patients with permanent AF compared to those with paroxysmal AF. The L-arginine/SDMA (p<0.031) ratios at 24 hours were significantly higher among patients with sinus rhythm compared to those with permanent AF. ROC analysis also revealed that plasma SDMA cut-off level over 0.639 μmol/L discriminated permanent AF from paroxysmal AF or sinus rhythm with a 90.9% sensitivity and 77.1% specificity. Neutrophil-lymphocyte ratio also showed significantly higher value in individuals with both paroxysmal and permanent AF (p=0.029). Conclusions - Plasma level of SDMA could discriminate permanent from paroxysmal AF in the subacute phase of ischemic stroke. In addition, an increased neutrophil-lymphocyte ratio may suggest inflammatory process in the evolution of atrial fibrillation.

[Eight questions and answers about anxiety in the elderly in family practice ]

CSATLÓS Dalma, VAJDA Dóra, MOHOS András, GONDA Xénia

[Anxiety is one of the most common psychological disorders in the elderly. Physical illnesses contribute to its development, but the opposite is also true: anxiety adversely affects the prognosis of many somatic illnesses, thus significantly enhancing morbidity and mortality. Therefore, the recognition and adequate treatment of anxiety disorders in the elderly are especially important in family practice, too. With the increase of life expectancy, the problems and illnesses of the elderly receive more and more attention in medical practice and anxiety cannot be ignored either, because the early detection of its symptoms improves the quality of life and reduces the chance of bad prognosis. ]

[Depression in medical practice - the possibilities of diagnosis and treatment]

OSVÁTH Péter

[Nowadays, there is an increasing incidence of depressive mood disorders, so we have more and more depressed patients in everyday clinical practice. Unfortunately, in many cases, this is not recognized and thus the treatment of depressed patients is not adequately addressed. Untreated depression not only increases the burden of the patient and his environment, but leads to serious and dangerous psychic and somatic complications. However, with modern and complex psychopharmacological, psychotherapeutic and sociotherapeutic methods, depressive mood disorders can be effectively treated. In this paper I review the etiologic background, the characteristics of depressive mood disorders and the most important steps of making diagnosis, as well as the state of the art therapeutic options. Rapid recognition and effective treatment of depressive symptoms has important therapeutic and preventive significance, so today, besides psychiatrists, there is an increasing role for general practitioners and other specialists (internists, neurologists, etc.).]

[The liaison between internal medicine and psychiatry can be life-saving in the treatment of severe anorexia nervosa]

SZÉNYEI Gábor, BENE László, TÚRY Ferenc

[INTRODUCTION - In the severe forms of anorexia nervosa hospitalization may be required, and the somatic treatment is provided in a department of internal medicine. In such cases, collaboration between internist and psychiatrist is essential. Psycho­logical support is necessary even in the period of nutritional rehabilitation. This can be applied in the framework of consultation-liaison psychiatry. After the initial weight gain providing psychotherapy in an outpatient setting is fundamental. In the case of anorexic patients who maintain a close relationship with the family, family therapy is the most effective treatment. CASE REPORT - A 26-year old female patient with anorexia was hospitalized in a department of internal medicine after an extreme emaciation, her body mass index was 11.6. During this period there was a psychiatric consultation involving the fa-ther of the patient as well. Her body weight increased, and outpatient family therapy was initiated. Fifteen family sessions were conducted in nine months, with special focus on the separation-individuation process. At the end of the therapy a full remission could be observed, with a normal body weight, and her periods returned. After a four-month follow-up her state was stable, and she got married. CONCLUSION - Interdisciplinary collaboration can be cardinal when somatic and psychological disorders are interwoven. The role of family therapy is crucial in those cases where emotional separation from the family of origin is difficult, even if the patient does not live with the parents any longer. ]

Isocitrate dehydrogenase mutations in defining the biology of and supporting clinical decision making in glioblastoma

KÁLOVITS Ferenc, TOMPA Márton, NAGY Ádám, BERNADETTE Kalman

Background and purpose - Oncogenesis is related to a sequential accumulation of somatic mutations. Comprehensive characterizations of the genomic landscapes have been completed recently for several tumors, glioblastoma being among the first ones. Our own translational research studies have been focused on defining molecular subtypes of glioblastoma in the clinical setting because of an expected prognostic and therapeutic utility of the information. Somatic mutations in genes of the isocitrate dehydrogenase (IDH) enzyme family appear to be among the best-defined biomarkers that also influence tumor behavior and confer clinical utility. Methods - We have reviewed the literature including our own results to summarize basic science and clinical correlates of IDH mutations. Results - The surveyed data reveal genomic, transcriptomic, epigenomic and biochemical consequences of IDH mutations in the context of glioblastoma biology and phenotype. In addition, a few studies highlight the therapeutic potential of targeting IDH, although thus far all tests have only been conducted in the preclinical setting. Conclusions - Somatic mutations in isoforms of IDH genes represent important biomarkers that correlate with biochemical, biological and phenotypic features of glioblastoma, and may also facilitate the development of new therapeutic strategies complementing the currently available approved protocols.

[Why is it important and ethical to treat anxiety patients?]

RADICS Judit

[The identification of anxious patiens is not always an easy task. The diagnose is clear in that case, when the symptoms (psychic or somatic) are evident or/and patients complain about anxiety. Anxiety itself is not a pathological symptom if it is adequate in strength and duration. Anxiety reactions have large individual variety -, they are pathological if inadequate and irrelevante and don’t match with the actual situation. According to epidemilogical data one third of patients of family doctors suffer from anxiety but somatic symptoms come to the front, so the patients participate in a great number of medical examinations. It is important to emphasise that medical examinations are necessary to preclude the possibility of any somatic disease. The di­ag­nostic criteria of DSM-5. are an excellent assistance for a good diagnosis. Anxiety is a risk factor for cardiological diseases and diabetes mellitus. The prevalence of anxiety disorders are 12.6-17.2%. Anxiety di­sorders are well-manageable, they need complex therapy: benzodiazepines, antidepressants, hypnotics and psychotherapy. They frequently co-exist with depression and insomnia so they have to be treated together. ]
