[AGRESSIVE STRATEGIES IN THE TREATMENT OF INFECTIVE ENDOCARDITIS]

LENGYEL Mária

[Without treatment, infective endocarditis (IE) is a fatal disease and in spite of contemporary diagnostic and therapeutic tools its prognosis is still poor. The most important first step is the early rise of clinical suspicion which should be confirmed by the new clinical criteria. Echocardiography is a major criterium: transesophageal echocardiography (TEE) is superior to transthoracic echocardiography (TTE) both in the diagnosis and in the detection of complications of infective endocarditis. Complications can be valvular (embolism, valvular dysfunction) or perivalvular (abscess, pseudoaneurysm formation) with hemodynamic consequences. TEE is recommended as the first line diagnostic technique (mostly in prosthetic valve infective endocarditis) or as a second study following negative TTE or positive TTE with high clinical risk factors or to define embolic risk. In addition to classical surgical indications, early ”preventive” indications are emphasized which can decrease the still high operative mortality. Improvement of outcome in infective endocarditis can only be expected with agressive management meaning early suspicion, early TEE and early operation.]

[OBESITY: THE EPIDEMIC OF OUR TIMES]

SIDÓ Zoltán

[The influence of changes in lifestyle on treatment and prevention of cardiovascular diseases are the objects of surveys in many places of the world. On the basis of clinical trials one can underline that the Mediterranean diet, with enhanced physical activity, changing lifestyle, cessation of smoking, reducing alcohol intake, maintaining normal weight can decrease dyslipidaemia, atherosclerosis and prevent cardiovascular diseases.]

[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.]

[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.]

[Decisional collisions between evidence and experience based medicine in care of people with epilepsy]

RAJNA Péter

[Background – Based on the literature and his long-term clinical practice the author stresses the main collisions of evidence and experience based medicine in the care of people with epilepsy. Purpose – To see, what are the professional decisions of high responsibility in the epilepsy-care, in whose the relevant clinical research is still lacking or does not give a satisfactory basis. Methods – Following the structure of the Hungarian Guideline the author points the critical situations and decisions. He explains also the causes of the dilemmas: the lack or uncertainty of evidences or the difficulty of scientific investigation of the situation. Results – There are some priorities of experience based medicine in the following areas: definition of epilepsy, classification of seizures, etiology – including genetic background –, role of precipitating and provoking factors. These are able to influence the complex diagnosis. In the pharmacotherapy the choice of the first drug and the optimal algorithm as well as the tasks during the care are also depends on personal experiences sometimes contradictory to the official recommendations. Same can occur in the choice of the non-pharmacological treatments and rehabilitation. Discussion and conclusion – Personal professional experiences (and interests of patients) must be obligatory accessories of evidence based attitude, but for achieving the optimal results, in some situations they replace the official recommendations. Therefore it is very important that the problematic patients do meet experts having necessary experiences and also professional responsibility to help in these decisions. ]

[Population-level QALY gain estimates with the use of cariprazine for patients with negative symptoms of schizophrenia in Hungary]

BENDES Rita, NÉMETH Bertalan, PITTER János György, KÓCZIÁN Kristóf, GÖTZE Árpád, KALÓ Zoltán

[INTRODUCTION - The loss in quality of life caused by mental illnesses has been growing in developed countries. This study aims to quantify the possible gains in quality of life by advantages of cariprazine therapy while treating patients with negative symptoms of schizophrenia in Hungary. Comparator therapy was defined as the currently available second-generation oral antipsychotic drugs. METHODS - In order to estimate the reachable gain in quality of life with cariprazine, an 8-state deterministic Markov cohort model was developed. Data was gathered from relevant scientific literature and public databases. The main assumptions regarding patient pathways have been validated by clinical experts, based on their real-life experience. The number of patients with negative symptoms of schizophrenia was estimated by the same methods as well. Sensitivity analyses were conducted on the input parameters. RESULTS - When compared with currently available second-generation oral antipsychotics, cariprazine generated an estimated increase of 0.05 quality-adjusted life years per patient in 2 years run. The deterministic sensitivity analysis confirmed the robustness of the results. Based on data of the National Health Insurance Fund and the scientific literature, a total gain of 450 quality-adjusted life years is expected at national level over a time horizon of 2 years. Even higher gains of QALY can be expected for longer time horizons. CONCLUSION - Based on conservative estimates significant health gain can be ge­ne­rated, if all patients with negative symp­toms of schizophrenia would receive the adequate cariprazine therapy in Hungary in­stead of the currently used se­cond-ge­ne­ration oral antipsychotic drugs. ]
