There is a long history of research into body fluid biomarkers in neurodegenerative and neuroinflammatory diseases. However, only a few biomarkers in CSF are being used in clinical practice. One of the most critical factors in CSF biomarker research is the inadequate powering of studies because of the lack of sufficient samples that can be obtained in(More)
BACKGROUND The 'Multiple Sclerosis Quality of Life Instrument' (MSQOL-54) was recently validated in Hungarian, on more than 400 multiple sclerosis (MS) patients. The aim of the present study was to examine the impact on their overall quality of life (QoL) of the demographic and clinical data on these patients, and their scores on different QoL scales. (More)
In the possible role for human herpesviruses (HHV) in the pathogenesis of multiple sclerosis (MS) neither clear distinction between the two variants of HHV-6, nor the involvement of HHV-7 have been described. Therefore, we quantitated HHV-6 variant specific and HHV-7 reacting antibodies in the CSF of 13 patients with MS or other neurological disorders by(More)
Multiple sclerosis (MS) is a chronic, demyelinating disease of unknown origin. Sophisticated analytical methods have made it possible to measure small biologically active molecules at low endogenous levels, and understand their role in the network of other biologically active compounds actively involved in inflammatory and neurodegenerative processes.(More)
OBJECTIVES The aim of this study was to determine the prevalence of multiple sclerosis in a population in South Hungary. METHODS The diagnosis was established with the aid of the Poser diagnostic criteria and the degree of physical disability was determined on the Kurtzke expanded disability status scale (EDSS). The present medical state (EDSS score) was(More)
BACKGROUND Familial factors influence susceptibility to multiple sclerosis (MS) but it is unknown whether there are additional effects on the natural history of the disease. METHOD We evaluated 1,083 families with > or =2 first-degree relatives with MS for concordance of age at onset, clinical course, and disease severity and investigated transmission(More)
The mutual involvement of dopamine and its metabolites in the nervous and immune systems has the potential to provide information on the interaction of these two systems. During a 24-hour period, we used capillary electrophoresis with electrochemical detection to repeatedly measure the intracellular catecholamine concentrations in the peripheral blood(More)
Circumstantial evidence suggests the involvement of sympathoadrenergic mechanisms in the progress of multiple sclerosis (MS). We studied peripheral blood lymphocytes from MS patients. The levels of dopamine (DA), norepinephrine (NE), epinephrine (E) and their metabolites in extracts of lymphocytes from 58 MS patients and 19 healthy controls were measured by(More)
BACKGROUND Neurofilament proteins (Nf) are highly specific biomarkers for neuronal death and axonal degeneration. As these markers become more widely used, an inter-laboratory validation study is required to identify assay criteria for high quality performance. METHODS The UmanDiagnostics NF-light (R)enzyme-linked immunoabsorbent assays (ELISA) for the(More)
Many patients with multiple sclerosis (MS) show cognitive and emotional disorders. The purpose of this study is to evaluate the role of contingency learning in decision-making in young, non-depressed, highly functioning patients with MS (n=21) and in matched healthy controls (n=30). Executive functions, attention, short-term memory, speed of information(More)
