[The medical impact of hepatitis C (HCV) is significant worldwide. The main consequences are chronic hepatic injury, cirrhosis, and hepatocellular carcinoma formation. The estimated global prevalence is 3% with 180 million infected people worldwide. The prevalence <1% in Hungary. The prevalence increased between 1990 and 2005 in East Asia, Western Europe, and West sub-Saharan Africa. There is characteristic geographical distribution of the main HCV genotypes. The mode of transmission can not be identified of 40% of cases. The most frequent transmission is the intravénás drug injection in the developed countries, and unsafe health procedures in developing countries. The sensitive, nucleic acid amplification testing, identification of high-risk groups, development of vaccination would help the HCV prevalence in the future. ]

[Recognition of the characteristics of rare types of arthritis]

ROJKOVICH Bernadette, MÉSZÁROS Györgyi

[Recognition of the characteristics of arthritis is crucial for making a correct diagnosis. Several aspects of the history and physical examination could help the diagnosis, such as the mode of onset (acute, insidious), duration of symptoms (self-limiting, chronic), number of affected joints (mono-, oligo-, polyarthritis), distribution of joint involvement (symmetrical, asymmetrical), localisation of affected joints (axial, peripherial) and sequence of involvement (additive, migratory, intermittent). Other important aspects for the correct diagnosis are the characteristics of the patient (gender, age, family history) and the presence or absence of extra-articular features of disease. The articular pattern may change with time in the course of a disease, and the single clinical pattern of joint disease may correspond to more than one diagnosis. Evidence of some distinct articular patterns may limit the spectrum of diagnostic options and reduces unnecessary diagnostic testing. The diagnostic process may require the addition of laboratory examination, imaging techniques, and other tests to refine the analysis. In this article, we report a case where joint punction and histological elucidation was necessary to make the correct diagnosis, because a syndrome of acute, destructive sterile arthritis mimicking articular infection might be present in a variety of joint disorders. In this paper, we highlight those characteristics that are distinctive for particular rheumatological disorders, in order to help starting treatment early.. In a substantial number of patients the cause of the diseases remains undetermined. However, a detailed anamnesis and physical examination remain the cornerstone of a diagnostic evaluation. ]

[The possibilities of pharmacological treatment of obesity]

PADOS Gyula, SIMONYI Gábor, BEDROS J. Róbert

[There have been attempts to treat obesity with medicines for nearly 100 years, since the discovery of ephedrine. For decades amphetamine derivates and agents stimulating or inhibiting the release of noradrenaline and dopamine have been applied. However, most of theses drugs had to be gradually withdrawn, due to their adverse effects on the cardiovascular and central nervous system or their sympaticotonic effect. Dexfenfluramine (Isolipan), which was introduced in the 90s, did not have such side effects, but it turned out to potentially cause valvular heart disease. Finally, sibutramin (Reductil) was introduced, which again had to be withdrawn in 2010 due to its hypertensive and cardiovascular side effects. After all, we were left without any appetite-suppressant drugs. Orlistat therapy, (Xenical 120 mg, alli 60 mg - OTC), which inhibits the absorption of fat, can eliminate only 30% of the consumed food's fat content, at the price of gastrointestinal side effects. The latest result of research carried out wordwide is that in 2012 the FDA approved commercial distribution of the selective 5HT2/c serotonin agonist lorcaserin (Belviq), which enhances satiety, in the USA. Unfortunately, in 2013 the EMEA temporarily postponed the lauch of this drug, until certain adverse effects are excluded. For diabetic patients, the GLP-1 agonist exenatid and the GLP-analog liraglutid, which can also reduce body weight, are available in the form of injections. ]

[The impact of vitamin D in infertility and the role in pregnancy and in nursing period]

SPEER Gábor

[Various medical associations issue different recommendations for the prevention and treatment of vitamin D deficiency. These significant differences are partly explained by the different definition of normal vitamin D level and the use of completely different mathematical models to predict the increase in vitamin D level as a response to therapy. According to the Institute of Medicine, the target vitamin D level is 20 ng/ml, whereas the Endocrine Society recommends 30 ng/m as the minimum target value. These differences show that the two Society have different views on the risk of adverse effects. Screening, however, is not recommended by either society. In this review I summarize the role of the vitamin D supplementation in the prevention of infertility. Also, I suggest the protective effect of the vitamin D during the pregnancy. In my opinion screening program against D hypovitaminosis should be performed in case of infertility and in pregnancy, because data show a protective role of vitamin D against many disease of newborn. ]

[Transmission of antibodies from mother to offspring: evolutionary aspects]

BAINTNER Károly

[The earliest known form of transmission of antibody is the transport from the maternal circulation into the yolk during vitellogenesis (in birds and reptiles), followed by endodermal uptake and transport into the embryonal circulation. During the early mammalian evolution lacteal secretion and the development of the placenta opened new ways to feed the young. These changes also resulted in alterations in sites and mechanisms of transmission of immunoglobulins. In a few species (e.g. rabbit and rodents) the yolk-less yolk sac gained a new function, i.e. the absorption of uterine secretion. In most of the mammalian species the neonatal type Fc-receptor (FcRn) plays a key role in the transmission and confers IgG-selectivity on the process. In ungulates undigested colostral proteins, including antibodies, are absorbed non-selectively by the gut, mediated by sizable transport vacuoles. The limited postnatal transmission period (24 to 48 h) is compensated by the considerable length of the small intestine and the efficiency of absorption. In the human chorioallantoic placenta the two steps of transmission (maternal secretion and absorption by the offspring) were reduced to a single step. Absorption of IgG is often carried out in a proteolytic environment (yolk sac, gut lumen, intestinal vacuoles), and as a result, different mechanisms evolved for the protection of antibody.]

[Epidemiology, cost and economic impact of cerebral palsy in Hungary]

FEJES Melinda, VARGA Beatrix, HOLLÓDY Katalin

[Objective - The purpose of our communication was to determine the total cost of cerebral paretic patients in Hungary between 0 and 18 years and to assess their impact on the national budget. Methods - Based on the data of Borsod county we calculated the CP characteristics. The cost of CP was determined by routine care of individuals. Lost Parental Income and Tax were calculated on the basis of average earnings. The ratio of GDP, Health and Social Budget and Health Budget to CP is based on CP annual average cost and frequency. We have developed a repeatable computational model. Results - Of the risk groups, premature birth (30.97%), low birth weight (29.64%), perinatal asphyxia (19.47%) were the most common. Source is unknown of 37.61% of the cases. CP prevalence was 2.1‰. The two-sided (59.7%) and the one-sided (19.0%) spastic pareses dominated. The most serious form is the two-sided spastic paresis (42.5% GMFCS 3-5 degrees). Epilepsy was 22.0%, incontinence was 27%, mental involvement was 46%. Care for one child up to 18 years of age costs an average of 73 million HUF (€ 251,724). The lost family income was 27.36 million HUF (€ 94,345), and lost tax and health care contributions were 14.46 million HUF (€ 49,862). Additionally, 0.525% of the GDP, 0.88% of the full health and social budget and 1.83% of direct medical costs were spent for CP families. Conclusion - The cost of CP disease is significant. Costs can be reduced by improving primary prevention. From the perspective of the family and government, it is better to care for families so they can take care of their disabled children.]

[Elderly patients with end-stage renal disease, its epidemiology and questions regarding it in Hungary]

SZEGEDI János, KISS István

[The number of elderly people and the kidney disease’s importance connected to it has increased worldwide, therefore the chronic kidney disease became an endemic. Parallel to the dwindling of population the people in it age. Because of the men’s higher mortality rate the proportion of women in the elderly is greater. Prognosis indicates that by 2060 every third citizen will be aged 65 or more. Between 1990 and 2015 the life expectancy at birth increased by 6.95 years in the case of men (in 1990 it was 61.13, and in 2015 it was 72.08) and by 4.9 years in the case of women (in 1990 it was 73.7, and in 2015 it was 78.6) in Hungary. Chronic kidney disease concerns 10 to 14 % of the population and 1% of all of them suffers from end stage kidney failure. In the end of 2015 3.52 million patients received kidney replacement therapy around the globe (2.42 million received hemodialysis, 329000 received peritoneal dialysis and 704 000 lived with transplanted kidneys). Of all the risk factors of chronic kidney disease age, hypertension, diabetes mellitus and obesity stand out as the most important ones. The kidneys’ anatomy and function change in elderly age, making it possible for the kidney disease to manifest in greater numbers. The elderly dialysis patients’ number increases worldwide which is connected to their higher life expectancy and better life prospects which on the other hand ultimately means that more and more patient lives to suffer from kidney disease. It cannot be disregarded either that the increasing number of elderly patients suffering from hypertension or diabetes means that because these are causes of kidney disease, the latter’s numbers are also increasing. International data indicates that in the case of incident ESRD patients their number was between 68-2784 and the older than 75 years was 142-1660 per million population. In Hungary there was 778/pmp and 677/pmp, respectively. In 2015 the ratio of incident dialysis patients the ones aged above 65 was 58,9% in the case of incident patients and 50,3% in the case of prevalent patients. The ratio of the ones aged above 75 was 28,2% in the case of incident patients and 22,6% in the case of prevalent patients. The number of elderly dialysis patients differs by region too. Dialysis treatment started in elderly age requires special knowledge and teamwork, similarly to the question of refusing the treatment. The latter team work, adequate experts (doctors and nurses) and the related professions’ representatives build the foundations of a proper clinical practice.]
