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.

[Experimental investigation of the complex energy balance]

GARAMI András

[The complex energy balance includes maintenance of both normal body mass and body temperature. In the homeostasis regulation it is important that the activities of several physiologic processes are balanced with each other, for example, the balance between food intake and energy expenditure is crucial to maintain normal body mass, while the balance between heat production and heat loss is vital in determining body temperature. Obesity and loss of body weight, as well as fever and hypothermia are consequences of the dysregulation in energy balance. In our research, we studied receptorial and neurohumoral mechanisms involved in the maintenance and in the impairment of energy balance. This paper gives an overview of our most important findings, which served as the basis of the application submitted to and awarded with 3rd prize by the Prof. Dr. Laszlo Romics Memorial Foundation. We review the physiologic role of transient receptor potential channels, mostly of vanilloid-1 (formerly: capsaicin receptor) in the regulation of body temperature and body mass. Among the neuropeptides which take part in the maintenance of energy balance, we present the thermoregulatory effects of alpha-melanocyte stimulating hormone and pituitary adenylate cyclase-activating polypeptide. Last, among the molecular mechanisms of systemic inflammation, which is characterized by thermoregulation disorders (e.g., fever, hypothermia), we recap the role of the vanilloid-1 and neurokinin-1 receptor, and bilirubin.]

[The Galilei of Bertolt Brecht and László Németh]

KELEMEN Gábor, ERDŐS Márta

[The trial of Galileo, who abjured his scientific convictions in the face of the Inquisitions was the most persistent and disturbing artistic theme of both Bertolt Brecht’s and Németh Laszlo’s writing careers. All three of them attended medical school. Galileo and Brecht never graduated whilst Németh’s medical work was subordinated to the art which became his vocation. The authors examine the genesis of Brecht’s and Németh’s dramas on Galileo, the possible effect of their medical studies or practice and their illnesses on their plays, and compare the work of the artists. This paper shows the process of their evaluating and re-evaluating their works and their struggle for further development of their artistic vision. Brecht’s and Németh's dramas, together with their formations and effects, can illuminate our understanding of the historically changing perpectivity of the scientific and artistic truth. ]

[Kidney transplantation in Hungary, 2010]

LANGER Róbert, TORONYI Éva

[Hungarian kidney transplantation has been established with three milestone operations. In 1902 Emerich Ullmann showed the technical feasibility of renal transplantation on dogs, and later the living donor transplant of András Németh in 1962 and the program starting operation of Ferenc Perner in 1973 already meant the real possibility for Hungarian patients. More than 5000 kidney transplantations were done since, and the operations are now made at the four university medical schools centers. In 2009 248 renal transplantations were done in our country (Budapest: 148, Szeged: 51, Pécs: 39, Debrecen: 34), from which 24 were living donor and nine combined kidney-pancreas cases. Despite the worsening financing situation in the health care system the numbers of transplantations are stable within a 15 year period, but this means a marked decrease in international comparison. In our country, the ratio of living donation is low, there is no paired donation, incompatible transplantation, the problems of hypersensitive patients are unresolved, and there is no old-for-old program. The solution to all of these problems could be joining to Eurotransplant, which is the definite wish of the transplant society based on the positive Slovenian and Croatian examples.]
