[Although the differential diagnosis of asthma is simple in most cases, there are cases causing difficulties. Beside as an aid in diagnosis, there is a growing need for new tests to monitor airway inflammation to optimize and monitor the effect of treatment. Following the traditional methods used in everyday clinical practice a new method, the measurement of exhaled nitric oxide was introduced in the past decade. With this method, completely new information can be obtained about asthma supplementing other results in diagnosis making and disease monitoring. It is also expected to become the part of clinical practice in the next few years. The concentration of exhaled nitric oxide is elevated in asthmatic patients and its elevation is positively related to the degree of eosinophilic airway inflammation and symptoms. This measurement is approved in the European Union and in the USA for clinical use to monitor the effectiveness of anti-inflammatory treatment in asthma.]

[CLINICAL EXAMINATION OF ENZYME CATALASE AND ITS MUTATIONS IN HUNGARY]

GÓTH László

[Hydrogen peroxide is formed during physiological and pathological processes in the human body. Hydrogen peroxide in high concentration and its more reactive compound (hydroxyl radical) can damage cells. Recent findings show that hydrogen peroxide in low concentration is required for many physiological pathways of cell signaling such as diabetes, platelet activation, inflammation, immune response. In human tissues the steady state concentration of hydrogen peroxide changes between 0.1 nmol/l-100 micromol/l. The main regulator of hydrogen peroxide metabolism is the enzyme catalase. This enzyme has a fast and high activity on high hydrogen peroxide concentrations and it shows a weak effect on its physiologic concentration. Acatalasemia, the inherited deficiency of enzyme catalase seems to be rather a syndrome than a simple enzyme deficiency as it was thought earlier. It is associated with changes in lipid, carbohydrate and erythrocyte metabolisms. Contrary to the the worldwide (11 countries) distribution of acatalasemia only two syndrome causing catalase mutations have been reported from Japan. Recently, four novel catalase mutations detected in one acatalasemic and 12 hypocatalasemic Hungarian families which mutations are responsible for the decreased catalase activity.]

Creutzfeldt-Jakob Disease: A single center experience and systemic analysis of cases in Turkey

USLU Ilgen Ferda, ELIF Gökçal, GÜRSOY Esra Azize, KOLUKISA Mehmet, YILDIZ Babacan Gulsen

We aimed to analyze the clinical, laboratory and neuroimaging findings in patients with sporadic Creutzfeldt-Jakob disease (CJD) in a single center as well as to review other published cases in Turkey. Between January 1st, 2014 and June 31st, 2017, all CJD cases were evaluated based on clinical findings, differential diagnosis, the previous misdiagnosis, electroencephalography (EEG), cerebrospinal fluid and cranial magnetic resonance imaging (MRI) findings in our center. All published cases in Turkey between 2005-2018 were also reviewed. In a total of 13 patients, progressive cognitive decline was the most common presenting symptom. Two patients had a diagnosis of Heidenhain variant, 1 patient had a diagnosis of Oppenheimer-Brownell variant. Seven patients (53.3%) had been misdiagnosed with depression, vascular dementia, normal pressure hydrocephalus or encephalitis. Eleven patients (87%) had typical MRI findings but only 5 of these were present at baseline. Asymmetrical high signal abnormalities on MRI were observed in 4 patients. Five patients (45.4%) had periodic spike wave complexes on EEG, all appeared during the follow-up. There were 74 published cases in Turkey bet­ween 2005 and 2018, with various clinical presentations. CJD has a variety of clinical features in our patient series as well as in cases reported in Turkey. Although progressive cognitive decline is the most common presenting symptom, unusual manifestations in early stages of the disease might cause misdiagnosis. Variant forms should be kept in mind in patients with isolated visual or cerebellar symptoms. MRI and EEG should be repeated during follow-up period if the clinical suspicion still exists.

[Obesity and cancer]

VALTINYI Dorottya

[The role of obesity in the development of cancer is well-known from ages. However, these days we witness the explosion-like increase of obesity, globally, but mainly in the economically advanced population, and, which is even more alarming, among youngsters. The prognosis of the obesity-related cancer is rather poor, therefore, the prevention, including the screening, have outstanding importance. Unfortunately, the participation of the obes persons, especially obes women, in these programs is very low. The diagnostics and therapies should consider the special features of obesity, which are related to the magnitude, distribution, composition of fatty tissue connected to the changes in pharmacokinetics. Moreover, the problems might be complicated with obesity-associated non-tumorous severe diseases (e.g. cardiovascular, diabetes type 2).This review covers different aspects of obesity-cancer relationships, with an emphasis on everyday oncology.]

[Novelties in the management of Hodgkin lymphoma]

ILLÉS Árpád, MOLNÁR Zsuzsa, MILTÉNYI Zsófia

[Hodgkin lymphoma is a lymphoproliferativ disease, it is about 12-18% of all lymphomas. It has typical morphologic, clinical and therapeutic features, which can distinguish from other lymphoma types. Due to risk- and PET/CT adapted treatment Hodgkin lymphoma is a curable lymphoma with an 80-90% long-term survival, however, refracter- and relapsed patients’ therapy is a great challange. Cure rate can increase due to the development of the diagnostic and treatment modalities, but the use of standard recommendation is necessary. The aim of this review is to show new WHO 2016 lymphoma classifi cation, role of the new diagnostic options, especially 18FDG-PET/CT, Lugano classifi cation and fi rst-line and salvage therapeutic possibilities and to introduce the immunotherapy, like brentuximab vedotin and PD1 inhibitors. Certain points of hemopoietic stem cell transplantation will be also covered.]

[NEW METHODS FOR NON-INVASIVE ASSESSMENT OF AIRWAY DISEASES]

HORVÁTH Ildikó

[In chronic obstructive airway diseases there are several unsolved questions regarding the early diagnosis, monitoring treatment, simple detection of exacerbations and the questions of differential diagnosis. These problems indicate the need for the development of new diagnostic methods and their application in clinical practice. This need is further emphasized by the fact that in most chronic airway diseases, including asthma and chronic obstructive pulmonary disease inflammation has a central role in the pathomechanism and its suppression is the main aim of treatment, but so far, we do not have adequate method for the assessment of inflammation intensity in clinical practice. In recent decades non-invasive sampling techniques directly from the airways have made a progress in respiratory research and at present some of them are available for clinical use. Among these techniques sputum induction, measurement of exhaled biomarkers including exhaled nitric oxide and mediators in exhaled breath condensate samples are used increasingly. The present review summarises our current knowledge on these methods and the most important findings obtained by their applications.]

[Clinical role of multigenic prognostic tests in breast cancer therapy]

GYŐRFFY Balázs

[Current clinical practice for breast cancer originates in “evidence based medicine”. In this, each tumor receives a therapy optimal for a given patient population - which might not be optimal for each individual patient. Multigenic tests determining expression of a set of genes can provide additional support in this decision process. Two such tests (MammaPrint and Prosigna) have already received FDA clearance. A number of additional test are commercially available (IHC4, Oncotype DX, EndoPredict, BCI). A common property of these assays is their utility in estrogen receptor positive early breast cancer. The main clinical problem answered by them is the necessity of adjuvant chemotherapy. To date, no reliable algorithm has been identifi ed capable to pinpoint the most effective chemotherapy combination for a given patient. Furthermore, there is no trustworthy test for triple negative breast cancer. The assays utilize different technologies (immunohistochemistry, gene chips, RT-PCR) and a discrepant list of genes - these result in discordance of the predictions for the individual patient. Despite these shortcomings, multigenic tests quickly gained foothold in breast cancer therapy decision process. Their utility is supported by the cost reduction for the health care providers by lowering the number of patients eligible for chemotherapy.]
