[OBJECTIVES - Antimicrobial resistance (AMR) in various bacterial infections is a growing problem in everyday clinical practice. The development of resistance is related to the clinical use of antibiotics, which substantially influences the efficiency of antimicrobial therapy. Inappropriately chosen therapy may increase the cost of treatment because of reduced efficacy and potential unwanted outcomes, adverse effects. Prolonged duration of treatment and increased use of diagnostic and therapeutic resources (including all medication expenses) contribute to the increased costs of treatment. The aim of our study was to demonstrate the differences in the total cost of therapy during hospitalization in certain patient groups, depending on the efficiency of the chosen antibiotic therapy. METHODS - We examined acute abdominal episodes, which represent one of the most typical surgical diseases. We analysed 59 hospital in-patient episodes that occurred in a six-month period, using aggregated hospital data. On the basis of the first choice of antibiotic we compared the average duration of antibiotic therapy and hospital stay, the incidence of medical complications and the cost of all these factors. RESULTS - The available results of our pilot study show that the length of hospital stay and the total cost of treatment may substantially increase even in the short term as a result of an inadequate choice of antibiotic, as the total cost of treatment is affected not only by the daily cost of antibiotic therapy, but also by its efficiency. In the long term, the risk of potentially developing resistance also necessitates an accurate choice of therapy, which requires institutional infection control and the prescription and implementation of protocols. These must be supported by cost-effectiveness analyses that include costs as well as results.]

[Occurrence of cardiometabolic risk factors among shift workers]


[INTRODUCTION - Shift workers have an impaired circadian rhythm, which might have an adverse effect on their health. In order to assess cardiometabolic risk in shift workers, a cross-sectional study was performed among active workers (aged 25-66 years, with a minimal shift working experience of 5 years). METHODS - In total 481 workers (121 men, 360 women) registered by the occupational health service were enrolled in our study. Most participants worked in the light industry (58.2%) or in public service (23.9%). Following questionnaire-based data recording, anthropometric measurements and physical examination were performed and fasting venous blood sample was taken for measuring laboratory parameters. Data from shift workers (n=234, 54 men and 180 women, age: 43.9±8.1 years) were compared with those of day workers (n=247, 67 men and 180 women, age: 42.8±8.5 years). RESULTS - Compared with day workers, shift workers had bigger weight (76.6±16.1 vs 73.9±17.6 kg; p<0.05), higher BMI index (27.5±5.3 vs 26.0±4.9 kg/m2; p<0.01) and systolic blood pressure (123±19 vs 119±16 mmHg, p<0.01), and higher prevalence rate of diabetes (4.3 vs 1.2 %; p<0.05) and cardiovascular diseases (3.8 vs 0.8 %; p<0.05). In addition, the proportion of participants who performed regular physical activity was lower (20.6 vs 38.7 %; p<0.001) and that of current smokers were higher (35.0 % vs 19.5 %; p<0.001) in shift workers than in day workers. In laboratory findings, only one difference has been found: HDL-cholesterol level was lower among women (shift workers versus workers: 1.56±0.32 vs 1.68±0.36 mmol/l; p<0.01). CONCLUSION - Long-term shift work (day-night) results in a less healthy lifestyle and worse cardiometabolic risk factors compared with day work. Thus, our study highlights the importance of measures for preventing cardiovascular diseases in shift workers.]

[Changes in infectology over the past two decades]


[Infectious diseases and various infections are the major causes of morbidity and mortality in developing as well as in industrialised countries. Despite the advances in the past decades in our understanding of microbes, efficient treatment of diseases and preventive approaches, more than 13 million people die every year due to infectious diseases. In the past two decades, more and more new pathogens and infections diseases have been emerging and old diseases that were almost forgotten have re-emerged. There are many new diseases for which we do not have or have hardly any efficient antimicrobial drugs and no efficient vaccines. Despite an increasing frequency of multi- and panresistant microbes, the development of new antibiotics to be used against these infections is unlikely to occur in the near future. The big pharmaceutical companies have stopped the research of antibiotics. In this situation, the only option we have is to use antibiotics rationally and to take prevention and control of infections seriously, both in the outpatient system and in hospitals. Preserving the effectiveness of currently used antibiotics is in everyone’s interest and is everyone’s responsibility.]

[Principles of antibiotic use in clinical practice]


[There has been a very significant reduction in morbidity and mortality associated with the use of antibiotics since they were first introduced, but, there has also been a concomitant rise in resistance among pathogens over the past 50 years. Moreover, antibiotics are sometimes associated with adverse events and their use can account for a significant proportion of the cost of treatment of some conditions. To ensure the optimal use of antibiotics doctors should use the most appropriate antibiotics to stop the spread of infection. In choosing the appropriate antimicrobial agent for the therapy of a certain infection several key factors must be considered: the most likely identity of the infecting organism, the potential antimicrobial susceptibility of the infecting organism and the host factors that influence the response to therapy. This publication is designed to introduce the concept of appropriate antibiotic therapy and how it can minimise the emergence of antimicrobial resistance while ensuring optimal patient management.]

[OBJECTIVE - To assess the costs, consequences and cost-effectiveness of pimecrolimus cream 1% in the treatment of children with atopic dermatitis in Hungary. METHODS - A Markov-model for atopic dermatitis developed by the Erasmus University (Rotterdam, the Netherlands) was adopted to the Hungarian health care setting. The model is based on a double-blind, multicenter, randomized, parallelgroup study. Patients were randomised (2:1) to receive pimecrolimus treatment (i.e. emollients, pimecrolimus, medium potency topical corticosteroids) or standard of care (emollients, vehicle, medium potency topical corticosteroids). The study was conducted in children and adolescents (2 to 18 years of age). Hungarian cost vectors were calculated by linking severity of disease as defined by Investigator’s Global Assessment (IGA) to average resource use. Resource use was multiplied by drug costs and unit costs as published in official databases. RESULTS - Pimecrolimus treatment has an incremental cost of HUF 143 897 over standard care. This additional cost of care resulted in an incremental 0.05 QALY gain over the 6 months period. The incremental cost effectiveness ratio was 2 863 913 HUF/QALY for the pimecrolimus therapy. CONCLUSION - Pimecrolimus is more costeffective than many other health care interventions currently reimbursed by the Hungarian National Health Fund.]

[Management of febrile neutropenia in the oncological practice]


[Febrile neutropenia is one of the most feared complications of anti-tumor therapy. It can either herald potentially fatal infection or contribute to suboptimal dose-intensity of cancer treatment. Optimal management of affected patients is based upon a multi-disciplinary approach dependent on several factors. Knowledge on institutional epidemiology and predefi ned management strategies improve quality and outcome of anti-infective therapy. In an era of more and more resistant pathogens and erosion of the antimicrobial armamentarium clinicians taking care of cancer patients carry increased responsibility in their professional activity. Here questions of practical importance related to prevention and therapy of neutropenic infections are outlined.]

[Development of anticoagulation in the past two decades]

SAS Géza

[In the past two decades we have witnessed a gradually increasing significance of both prophylactic and therapeutic anticoagulation. The importance of thromboprophylaxis has become widely accepted in the course of surgical interventions and in various other fields of medicine, too. The introduction of low molecular weight heparins was a milestone in this respect. The need for long-term anticoagulation has become a common problem. The various recent aspects and topics of anticoagulation have been described in the current Hungarian medical literature, therefore, I focus on two general problems of medicine of our days from the aspects of our subject. The evaluation of information on the new, direct-acting inhibitors (anti-IIa and anti- Xa),and their high price present great difficulies, especially in the case of long-term anticoagulation therapy. Clinical data and experiences have been collected from patients who are greatly different from the majority of patients in the real world. The lack of antidote may also be a serious problem in case of these new drugs, as urgent neutralization might be necessary, for example in case of serious bleeding, accidents etc. Today, cost-effectiveness of medical interventions and drugs has become a major aspect, therefore, the high price of new anticoagulants might prevent their use in the clinical practice. Despite the optimistic expectations regarding new anticoagulants, at present we have to strive to treat our patients with the currently available, effective but affordable drugs, widening and improving their use.]
