[THE USE OF EARLY BIOMARKERS IN PREVENTION. - THE MARKERS OF THE EXPOSITION, EARLY EFFECT AND INDIVIDUAL SENSITIVITY]

EMBER István, KISS István, SÁNDOR János, FEHÉR Katalin, NÉMETH Katalin, LUKÁCS Péter

[The molecular and predictive epidemiology plays more and more important role in the prevention of cancer. With the help of early biomarkers, high risk population could be identified for primary preventive intervention modalities. It uses both molecular biological methods and elements of risk assessment plus a testing system based on animal experiments. Its specificity is not high enough to establish the diagnosis but it can be used to monitor the disease and to follow the effectivity of the therapy (e.g. "minimal residual disease") and the preventive interventions. It is also suitable for risk assessment with the markers of individual susceptibility. As to everyday practice there are many problems because of limited therapeutic possibilities, but we hope that the molecular and predictive epidemiology becomes an important part of medicine in the near future.]

[NEW MODALITIES IN THE TREATMENT OF CHRONIC VIRAL HEPATITIS C: PEGYLATED INTERFERONS]

GERVAIN Judit, NEMESÁNSZKY Elemér, CSEPREGI Antal

[Interferon-α proved to be the most effective therapy of chronic hepatitis C. Its combination with ribavirin enhances the antiviral activity and this modality has become the therapeutic standard recommended worldwide during the past few years. Metaanalysis of the international studies revealed that only 12-19% of the patients became virus-free following a 48-week long course of α interferon monotherapy. The combination treatment with ribavirin for 48 weeks increased the proportion of sustained responders to 35-45%. The introduction of pegylated interferons resulted in significantly higher response rates. The new therapeutic possibilities are due to the modified pharmacokinetic characteristics of the drug by changing the size and the structure of the molecules. Multicentre studies investigating the clinical effectiveness of the 40 kD sized pegylated interferon α-2a as well as the 12 kD sized pegylated interferon α-2b in combination with ribavirin reported 56% and 54% response rate, respectively. However, there is significant heterogeneity in the results according to the type of drug administered and to the genotype of the hepatitis C virus, as well as in the basal viral level and the stage of hepatic fibrosis, respectively. The message and the conclusion of the viral kinetic studies are worth remembering: if the result of the HCV nucleic acid test is still positive at week 12 or 24, therapy should be ceased due to the patient non-responder status. Since pegylated interferons are also available in Hungary the authors felt useful to give an overview of the current knowledge, summarizing the results of the relevant studies and provide a suggested state-of-the-art therapeutic protocol based on international consensus.]

[Vaccines against COVID-19 pandemic]

FALUS András, SZEKANECZ Zoltán

[The rapidly spreading SARS-CoV2 respiratory virus has evoked an epidemic with serious aftermath around the world. In addition to the health effects, the global economic damage is actually unpredictable. At the same time, the pandemic has launched a series of unprecedented collaborative scientific research, including the development of vaccines. This study summarizes up-to-date information on vaccines, immune memory, and some emerging clinical effects.]

[A short chronicle of three decades ]

KAPRONCZAY Katalin

[Hungarian professional periodicals started quite late in European context. Their publish­ing, editing and editorial philosophy were equally influenced by specific historical and political situations. Certain breaking points of history resulted in termina­tion of professional journals (War of In­de­pendence 1848-1849, First and Se­cond World Wars), however there were pe­riods, which instigated the progress of sciences and founding of new scientific journals. Both trends were apparent in years after the fall of former Hungarian regime in 1990. The structure of book and journal publishing has changed substantially, some publishers fell “victim” others started successfully as well. The latters include the then-established publishing house Literatura Medica and its own scientific journal, Lege Artis Me­di­cinae (according to its subtitle: New Hun­garian Medical Herald) issued first in 1990. Its appearance enhanced significantly the medical press market. Its scientific publications compete with articles of the well-established domestic medical journals however its philosophy set brand-new trends on the market. Concerning the medical community, it takes on its problems and provides a forum for them. These problems are emerging questions in health care, economy and prevention, in close interrelation with system of public health institutions, infrastructure and situation of those providing individual health services. In all of them, Lege Artis Medicinae follows consequently the ideas of traditional social medicine.]

[Focus on Lege Artis Medicinae (LAM)]

VASAS Lívia, GEGES József

[Three decades ago, LAM was launched with the goal of providing scientific information about medicine and its frontiers. From the very beginning, LAM has also concerned a special subject area while connecting medicine with the world of art. In the palette of medical articles, it remained a special feature to this day. The analysis of the history of LAM to date was performed using internationally accepted publication guidelines and scientific databases as a pledge of objectivity. We examined the practice of LAM if it meets the main criteria, the professional expectations of our days, when publishing contents of the traditional printed edition and its electronic version. We explored the visibility of articles in the largest bibliographic and scientific metric databases, and reviewed the LAM's place among the Hun­ga­rian professional journals. Our results show that in recent years LAM has gained international reputation des­pite publishing in Hungarian spoken by a few people. This is due to articles with foreign co-authors as well as references to LAM in articles written exclusively by foreign researchers. The journal is of course full readable in the Hungarian bibliographic databases, and its popularity is among the leading ones. The great virtue of the journal is the wide spectrum of the authors' affiliation, with which they cover almost completely the Hungarian health care institutional sys­tem. The special feature of its columns is enhanced by the publication of writings on art, which may increase Hungarian and foreign interest like that of medical articles.]

[Association between cyclothymic affective temperament and hypertension]

NEMCSIK János, BATTA Dóra, KŐRÖSI Beáta, RIHMER Zoltán

[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]

[Tracing trace elements in mental functions]

JANKA Zoltán

[Trace elements are found in the living organism in small (trace) amounts and are mainly essential for living functions. Essential trace elements are in humans the chromium (Cr), cobalt (Co), copper (Cu), fluorine (F), iodine (I), iron (Fe), manganese (Mn), molybdenum (Mo), selenium (Se), zinc (Zn), and questionably the boron (B) and vanadium (V). According to the biopsychosocial concept, mental functions have biological underpinnings, therefore the impairment of certain neurochemical processes due to shortage of trace elements may have mental consequences. Scientific investigations indicate the putative role of trace element deficiency in psychiatric disorders such in depression (Zn, Cr, Se, Fe, Co, I), premenstrual dysphoria (Cr), schizophrenia (Zn, Se), cognitive deterioration/de­mentia (B, Zn, Fe, Mn, Co, V), mental retardation (I, Mo, Cu), binge-eating (Cr), autism (Zn, Mn, Cu, Co) and attention deficit hyperactivity disorder (Fe). At the same time, the excess quantity (chronic exposure, genetic error) of certain trace elements (Cu, Mn, Co, Cr, Fe, V) can also lead to mental disturbances (depression, anxiety, psychosis, cognitive dysfunction, insomnia). Lithium (Li), being efficacious in the treatment of bipolar mood disorder, is not declared officially as a trace element. Due to nutrition (drinking water, food) the serum Li level is about a thousand times less than that used in therapy. However, Li level in the red cells is lower as the membrane sodium-Li countertransport results in a Li efflux. Nevertheless, the possibility that Li is a trace element has emerged as studies indicate its potential efficacy in such a low concentration, since certain geographic regions show an inverse correlation between the Li level of drinking water and the suicide rate in that area. ]
