[While severe asthma associated with high morbidity affects a relatively small proportion of all patients with asthma, it requires special attention and innovative treatment approaches. Although asthma is by definition characterized by reversible airflow obstruction, the obstruction becomes fixed to some extent and refractory to corticosteroids with the progression of the disease. The underlying change in this phenotype is airway wall remodelling. In allergic asthmatic patients who remain symptomatic despite highdose inhaled corticosteroid therapy, blockade of IgE with omalizumab confers appreciable clinical benefit. Chronic severe asthma is also accompanied by a marked increase in TNFproduction that might contribute to corticosteroid resistance. In accordance with this, TNF blockade with entanercept has been shown to improve asthma controll and at the same time to reduce bronchial hyperresponsiveness. Identification of new susceptibility genes, such as ADAM33, will provide further targets for therapy, which in turn can result in the development of treatment tools that modify the natural course of asthma and reverse the changes associated with airway remodelling, rather than simply suppress inflammation and dilate the airways.]

[TREATMENT OF HYPERTENSION - RECOMMENDATIONS FOR THE PRACTICE]

PÁLL Dénes

[Hypertension is one of the most common diseases with a prevalence of over 25%. Despite of the availability of modern therapeutic options, the proportion of well-controlled patients is low. Before starting the treatment of patients with hypertension, it is essential to assess cardiovascular risk factors, co-morbidities and damages to target organs, in addition to repeated blood pressure measurements. The author first reviews the non-pharmacological treatment options of hypertension, then summarizes the most important characteristics of first-line antihypertensive agents (diuretics, beta-receptor blockers, calcium channel antagonists, angiotensin converting enzyme inhibitors, angiotensin receptor blockers). Considering the complex pathomechanism of essential hypertension, the author details the advantages and options of combined antihypertensive therapy, touching on the combinations recommended in special conditions. The metabolic effects and side-effects of antihypertensive agents, which have recently gained increased significance, are also discussed. Modern hypertension care is aimed at maximally decreasing cardiovascular morbidity and mortality, and improving the patient's quality of life. Maximum decrease of cardiovascular risk not only involves proper blood pressure control, but also aggressive fight against other risk factors (e.g., diabetes, dyslipidaemia, smoking) and treatment of target organ damages and comorbidities.]

[CLINICAL ASPECTS OF NOCTURNAL GASTRO-OESOPHAGEAL REFLUX]

DEMETER Pál

[Gastro-oesophageal reflux that occur at night has special clinical features and thus require extra attention. During sleep most anti-reflux mechanisms diminish, which results in prolonged contact between gastric acid and oesophageal mucosa compared to reflux during the day. Nighttime reflux symptoms adversely affect quality of life, vitality, physical and mental health. A further important consequence is the potential exacerbation of respiratory disorders such as asthma and sleep apnea. There is increasing interest in the association between nocturnal reflux and certain extra-oesophageal symptoms, including reflux laryngitis and chronic cough. An increased risk of erosive damage and adenocarcinoma of the oesophagus are also observed among patients who report nocturnal reflux symptoms. The primary goal of treatment is to improve quality of life and reduce the risk of complications by decreasing the time of acid contact with oesophageal mucosa. Nighttime reflux symptoms are much more difficult to control than daytime symptoms. Treatment guidelines generally recommend lifestyle changes as the initial approach in managing nocturnal symptoms, however, this is successful in only a small proportion of patients. Evidence-based reviews and meta-analyses favour the use of proton pump inhibitors in the treatment of gastro-oesophageal reflux disease and reflux-oesophagitis. Proton pump inhibitors are the most efficient acid-suppressing agents and thus diminish the harmful effect of acidic gastric reflux on the oesophageal mucosa. In addition, by decreasing the volume of gastric acid, they reduce the tendency to reflux.]

[The importance of etanercept treatment in rheumatology]

ifj. GERGELY Péter, POÓR Gyula

[Rheumatoid arthritis, juvenile idiopathic arthritis, ankylosing spondylitis and psoriatic arthritis are inflammatory rheumatic conditions of unknown origin. Common characteristic features of these disorders include a relatively high prevalence, poorly understood pathogenesis and an unresolved treatment as well as a significant impact on mortality, morbidity and medical expenditures. The recognition of the central role of TNF-α in immune mediated inflammatory conditions, mainly in rheumatoid arthritis has led to the introduction of TNF-α blocking biological therapy into clinical rheumatology revolutionizing the management of these diseases. Etanercept is a human soluble TNF-α receptor attached to human IgG capable of effectively neutralizing TNF-α and lymphotoxin alpha. Since its introduction in 1998 as the first biological agent approved for RA, several clinical trials as well as everyday practice have proven its efficacy and safety. To date approximately 440 thousand patients, mostly with inflammatory rheumatic diseases have been treated with etanercept. In the present paper the pathophysiological role of TNF-α, the results of clinical trials of etanercept and its cost-effectivenes as well as issues regarding the use of etanercept in Hungary are reviewed.]

[ASTHMA THERAPY ACCORDING TO THE REVISED INTERNATIONAL RECOMMENDATION]

HERJAVECZ Irén, BÁNKÚTI Beáta, CSOMA Zsuzsanna

[A comprehensive workshop report entitled “A Global Strategy for Asthma Management and Prevention - Global Initiative for Asthma (GINA)” first published in 1995, has been widely adapted, translated and reproduced, and forms the basis for many national asthma guidelines. The 2006 report contains important new themes. It asserts that it is reasonable to expect that in most patients with asthma, control of the disease can be achieved and maintained, and recommends a change in approach to asthma management with asthma control, rather than asthma severity, being the focus of treatment decisions.]

[TNF-α blocking therapy in rheumatoid arthritis]

TAMÁSI László

[The research of pathomechanism of rheumatoid arthritis resulted in remarkable pragmatic results beyond the important theoretical knowledge. These observations led to the development of new effective agents, which were named as biological therapy and introduced in clinical praxis. The key factor of pathomechanism of rheumatoid arthritis is the proinflammatoric citokin TNF-α. It can be found on the top of the inflammation cascade where regulates many other inflammatory mediators and also plays an important role in the defence against infections and tumours. The author describes the TNF-α blocking agents used in clinical practice, their chemical and pharmacological feature, as well as their mode of action and the consequence of inhibition of TNF-α. He reviews the main results of the major clinical tests with infliximab, etanercet, and adalimumab. The results of these clinical studies demonstrate that the TNF-α blocking therapy gives clinical improvement in case of therapy resistant patients, decreases the number of swollen and tender joints, the pain, ESR and CRP, decreases the radiological progression, furthermore improves the quality of life. There are also some data about the favourable impacts observed during the early arthritis treatment. The TNF-α blocking therapy can be used effectively and safely in rheumatoid arthritis. In most cases the infusion reaction and the injection site reaction are not reasons for withdrawal from the study. The sideeffects, however, developed in increasing numbers during widespread applications. Among these the most important ones are the opportunist infection and the tuberculosis. In addition the sporadic occurrence of lupus-like symptoms, demyelinating disease, and aplastic anemia were reported. The fundamental requirements of the safety of the biological therapy are the professional indication and the careful monitoring during the treatment, the principle of which has been already prepared by the Professional College of the Rheumatology and Physiotherapy based on the international experience.]

[A NEW WAY TO TREAT ALLERGIC ASTHMA: ANTI-IGE THERAPY]

MAGYAR Pál

[Immunoglobulin E (IgE) plays a central role in the pathogenesis of the inflammation of the bronchial mucosa and airway hyperreactivity, which in turn produces the symptoms of allergic bronchial asthma. Omalizumab, the recently developed anti-IgE monoclonal antibody binds to the Cε3 region of the IgE molecule and thus prevents binding of the IgE to the surface of FCεRI receptor bearing cells (mast cells, basophils and antigen presenting dendritic cells). In the absence of cell-bound IgE, these cells are not activated and thus do not release inflammatory mediators and proinflammatory cytokines upon allergen exposition. Treatment with omalizumab significantly decreases the number of bronchial mucosal eosinophils and FCεRI positive cells, and the FCεRI receptor expression of the latter. Double blind controlled clinical studies have demonstrated that omalizumab treatment reduces the number of exacerbations and emergency room visits, the β2-agonist requirement and the dose of inhaled steroids, improves exspiratory airflow limitation, asthmatic symptoms and asthma-related quality of life in patients with moderate to severe allergic asthma. Low baseline FEV1, the use of high dose inhaled corticosteroids and a history of emergency asthma treatment in the past year are significant predictors of a better response to omalizumab. Omalizumab is tolerated well by patients. With the exception of local skin reactions, no significant difference in adverse events between patients taking omalizumab and control groups have been reported. According to the GINA (Global Initiative for Asthma) stepwise therapy protocol of asthma, omalizumab is indicated for severe asthmatics whose symptoms can not be controlled by inhaled corticosteroids and long-acting β2 agonists.]
