[The success of fixed combined amlodipine/atorvastatin (Amlator®) therapy in patients with hypertension and dyslipidemia]

KÉKES Ede

[In total 2606 patients with hypertension and dyslipidemia got combined antihypertensive and antilipid-treatment. The main component of therapy was amlodipine/ atorvastatin fixed combination in different dose variations. The goal of the study was to access optimal target blood pressure and lipid profile. The baseline average blood pressure value was 155.9/90.18 mmHg and it decreased to 132.77/80.04 mmHg during the six months therapy. The lipid profile also changed successfully: the average value of total cholesterol decreased from 5.97 mmol/l to 4.68 mmol/l, LDL cholesteron from 3.45 mmol/l to 2.49 mmol/l and serum triglyceride from 2.1 mmol/l to 1.69 mmol/l. We reached the target values in respect of LDL cholesterol (<2.5 mmol/l) and of triglyceride (<1.7 mmol/l) prescribed in guidelines for subjects with high cardiovascular risk. According to the global cardiovascular risk estimation (European Heart Score) the risk ratio in percent was significantly decreased in each age group, in both genders and in smoking or nonsmoking subjects.]

[The beginning and difficulties of peritoneal dialysis at the end of the last century - Part I. International experiences]

KARÁTSON András

[The theoretical background of peritoneal dialysis dates back to the 18th and 19th century. It was in 1923 when the first experimental and clinical experiences were summarised by Ganter from Munich. Of the Hungarian researchers Stephen Rosenak’s name can be mentioned, who was working in this field in Bonn in 1926 and later in London and New York. Obstacles to the spread of this treatment method was the lack of appropriate abdominal catheters, biocompatible solutions and equipment. The intermittent technique of the method was time consuming and, due to the conditions of that time, peritonitis frequently developed. The spread of the method was facilitated by the catheter constructed by Tenchkoff towards the end of the 1960s, the automatization of the treatment and later continuous ambulatory peritoneal dialysis (CAPD) described by Popovich and Moncrief. Further development of the method became possible by the use of the two-litre plastic bags instead of the bottled solution and later a twin-bag system employing the “flush before fill” technique. The occurrence of peritonitis developing during the treatment gradually decreased, in which Stephen I. Vas of Hungarian origin, working in Toronto as a professor of microbiology played an important role by constantly improving and modifying the principles of the therapy. Besides the infection in the abdominal cavity the bioincompatibility of the dialysis fluid presented another problem, which was solved by the use of essential amino acids, icodextrin instead of glucose and bicarbonate instead of lactate. By the turn of the century it became clear that the survival rate of peritoneal dialysis is very similar to that of hemodialysis in the second and third years following the treatment, while in relation to the quality of life it proved to be better. This observation has been proved in numerous clinical studies in the past decade and has been refined with regard to patients’ age, their primary and accompanying diseases. It is my intention to give account of the Hungarian experiences with peritoneal dialysis in the second part.]

[Paradigmal changes in renal replacement therapy. Dialysis and drug therapy of quality in chronic renal patients - Optimal and adequate opportunities of dialysis therapy]

KISS István, SZEGEDI János, FODOR Erzsébet, BARABÁS Noémi, REMPORT Ádám, AMBRUS Csaba, KULCSÁR Imre

[Researches over the past thirty years, many results have been related to acute and chronic renal failure pathophysiology, clinical characteristics and therapy. Can be more than just the uremic toxins and their characteristics of the regulation of salt and water balance, renal anemia treatment, uremic metabolic disorders, calcium phosphate and lipid metabolism dysfunction. Improve the quality of treatment and reduce mortality and options can be influenced by factors come to, therefore, execution and technique of dialysis therapy. We know the primary concern of the treatment period for reducing mortality. This is best for intermittent treatments increased (4.5-6 hours) treatment will help. Narrow scope is optional for the treatment several times a week treatment, the daily 8-hour long nightly therapy. The mortality of the patient significantly influenced by age, gender, co-morbidities, fluid balance and the CaxPO4. The technical side is the key factor influencing the dialysis fluid purity and membrane properties. The use of high-flux membranes is clearly improving the quality of treatment, the additional benefit of hemodiafiltration therapy, the mortality for those still controversial. For optimal dialysis adequacy, complexity may result in reducing mortality and improving the quality of life in chronic dialysis patients.]

[Optimizing the efficacy of triple combination therapy of chronic hepatitis C]

TORNAI István

[The outcome of chronic hepatitis C (CHC) therapy has been improved significantly. If sustained virologic response (SVR) is achieved, then it may prevent the occurrence of liver failure and hepatocellular carcinoma. With the currently used double combination therapy (peginterferon and ribavirin) SVR can be achieved in 40-50% of patients with genotype 1. In treatment naive patients, triple combination with protease inhibitors can result in 70-75% SVR. In treatment experienced patients, however, the result of the previous therapy, which mostly depends on the reaction to interferon (IFN), has a significant influence on the outcome of triple combination. INF sensitivity is the highest in relapsers, triple combination can achieve about 85% SVR, while in null responders this is only 30%. Viral resistance is a new phenomenon during triple combination therapy of CHC. In poorly IFN responsive patients the virus is effectively exposed to protease inhibitor functional monotherapy, leading to the rapid emergence of resistant virus. IFN sensitivity is well represented by the on-treatment viral response, therefore the knowledge of the previous viral response, relapse, a partial response or a null response is absolutely important. Optimization of triple therapy is crucial, since for a lot of patients with advanced liver disease it might be the last chance to achieve an SVR. The selection of the patients seems very important. Relapsers are the best candidates, there is no doubt with the indication. However, there are many debates for cirrhotic nullresponders, since the most virological failures are expected in this group. Prevention of viral resistance is crucial. PegIFN and ribavirin suppress both wild-type and resistant virus. PegIFN α-2a based treatment proved to be the most effective backbone for triple combination. This combination should be preferred especially for treatment experienced patients. Adherence to therapy is also critically important to prevent resistance. If resistant mutants appear, treatment should be stopped promptly.]

[Empirical examination of the persistence value among the students studying health-care at the beginning of student professionalization]

DINYÁNÉ Szabó Mariann, PUSZTAI Gabriella

[INTRODUCTION – Students in healthcare studies can help maintain the mental base and maintain their health if the lecturers know the degree of student persistence. When entering higher education, it is possible to measure the pre-university experience. Persistence determines the student's relationship to learning and can be a predictor of learning success. PARTICIPANTS AND METHODS – A questionnaire study (N = 200) of the 1st year student (N = 200) of the Health Care Organization (BSc) of the University of Debrecen and Semmelweis University. For the continuous Persistence Variable a descriptive statistical method was used, an independent two-sample t-test was used for comparison between groups, and Hedges-g was used to express the effect size. We used the GLM (General Linear Model) model for fitting the persistence model. By means of factor analysis, we constructed factors from the significant predictor variables of the GLM model, which helped us assessing students' chances of learning. To quantify the strength of evidence against null hypothesis P < 0.05 (5% significance) was chosen as a standard level for concluding that there is evidence against the hypothesis tested. Statistical analysis was performed with IBM SPSS Statistics 24.0 (SPSS, Chicago, IL). RESULTS – The persistence factor loadings can be divided into three types: high, medium and low. High persistence rearranges student preferences, low interest persistence, minimal interest in academic engagement. In the case of middle-ranking people, the importance of volunteering (life-experience) and friendship is paramount. CONCLUSIONS – The results indicate that at the beginning of the student life there is a willingness, diligence, acceptance of academic values, interest or lack of interest in future success studies. During the stu­dies, these features can be monitored and the necessary interventions can be made in time.]
