[INTRODUCTION - Based upon international and domestic research data authors summerize the humoral and cellular im­munregulatory disorders which can be found in the background of “immune me­diated abortions” (IMA). PATIENTS AND METHODS - Within the frame of a home research program a special examination protocol was elaborated in order to sepatare alloimmune habitual abortions from autoimmune and non immune backgrounds. After all other causes were excluded erythrocyte antibody inhibition assay (EAI) was used for measuring the serum level of FcgRII receptor blocking IgG antibody, because its lack an important diagnostic parameter. Among the cell mediated immunofuntional tests the mixed lymphocyte culture reaction (MLC) was the most useful. During the roughly last 16 years 67 out of 76 selected alloimmun IMA patients were administered Intratect IVIG treatment without any particular selection among them. IVIG treatment was first applied on the completed 5-6th week of pregnancy and doses of 0,3-0,4g/kg bodyweight per oc­casion were given 3 times with 3-week intervals. RESULTS - Altogether a significant rise in the serum level of blocking antibodies was shown after each IVIG treatment although a slight decrease was seen after every given dose. Of the 67 IMA patients 54 carried infants to term during the study period. In 4 cases of abortion no cause was identified with post hoc diagnosis. Thus the success rate of this type of IVIG therapy was 93.1% (58/54). Conclusion - In approprietly selected alloimmun IMA cases the IVIG generated immunoregulatory and antiimflammatory pathways may contribute to its net positive reproductive effect.]

[The cardiovascular risk of nonsteroidal antiinflammatory drugs]

AMBRUS Csaba, KISS István

[Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most common pain relief and anti-inflammatory medications all over the World, and many formulations are also available over-the-counter. Beyond the well-known gastrointestinal risks, emerging evidence supports increased incidence of cardiovascular events associated with the use of NSAIDs. This cardiovascular risk seems to be independent of the cyclooxygenase selectivity of these drugs. Distinct side effect profiles of various NSAIDs were summarized in a former issue of the Journal: LAM 2014;24(7): 327. In this paper, we aimed to summarize some of the yet unpublished results of a major research project of the European Medicines Agency (EMA), that was conducted in order to establish the relative risk of CV outcomes (myocardial infarction, ischaemic stroke and hospitalization for heart failure) associated with the use of various NSAIDs. In this epidemiological study, seven European healthcare databases on a source population of 35 million subjects were linked and analyzed. Most of the results are currently only available on the project homepage; however, analyses of heart failure data have already been published in a recent issue of The BMJ. ]

[Complex medical treatment of non small cell lung cancer - new challenges, new possibilities]

OSTOROS Gyula, SZONDY Klára

[Previously, it was suffi cient to differentiate small cell lung cancer (SCLC) and non small cell lung cancer (NSCLC) in the decision making process for the therapeutic strategy of lung cancer. Recently, the situation has changed signifi cantly. There are only few new cytotoxic agents, and platinum based chemotherapy remains the standard combination in the treatment of NSCLC. In the last decade no further development has been discovered in the treatment of SCLC. However, the new molecular diagnostic and therapeutic possibilities have altered dramatically the management of NSCLC. NSCLC could not be considered as a separate entity anymore. The complex medical treatment of advanced NSCLC includes the molecular target driven therapies the histopathological subtype based chemotherapies and the immunotherapy. Immunotherapy is a new challenge in the treatment of lung cancer. Tumor-vaccines, inhibition of immune checkpoint pathways are investigated in clinical trials. Ongoing studies will defi ne the true effi cacy of these drugs. The complex combination of genes, proteins, different molecular pathways and patients characteristics, called “panomics”, are all parts of the treatment of lung cancer in the daily clinical practice.]

[Gene modifi ed T cell therapy for patients with cancer]

HECZEY András

[T cells genetically modifi ed to express chimeric antigen receptors can combine the antigen specifi city of monoclonal antibodies with the cytotoxic function, active biodistribution and long term persistence of T cells. The approach can induce 90% complete remission rate in patients with CD19+ lymphoid leukemias; however, the in patients with solid tumors the antitumor effi cacy of CAR T cells have not reached similar levels yet. The increased levels of interleukin-6 due to T cell activation play key roles in the majority of side effects and using anti-IL-6 monoclonal antibody, tocilizumab can effectively treat these complications. Novel gene modifi cation strategies and improvements in CAR T cell manufacturing, the approach has the potential to fundamentally change the way patients with cancer are treated in the not too distant future.]

[Treatment of mesothelioma - an update]

MOLDVAY Judit, HEGEDŰS Balázs, KOVÁCS Ildikó, DÖME Balázs

[Malignant pleural mesothelioma is an aggressive tumor arising from the mesothelial cells lining the pleura. It is an asbestos related disease with increasing incidence both in Europe and in Hungary. This often fatal disease is characterized by rapid progression, and unfortunately, treatment options are very limited to date. Thus every effort should be made to better understand the pathological and molecular biological characteristics of this disease in order to develop new treatment strategies. This summary reviews the treatment options available today as well as the new therapeutic approaches at the experimental and clinical investigation stage.]

[Treatment of head and neck cancer]

KATONA Csilla, LANDHERR László

[Head and neck cancers cause worldwide a signifi cant problem in health care systems. Despite great advances in therapeutic modalities its prognosis has not changed in the past few decades. It is mainly caused by classical risk factors, like alcohol consumption and smoking, but in a signifi cant number of oropharyngeal cancers HPV infection plays a major role, which is associated with a new patient group characterized by a much better prognosis and therapeutic response. In the diagnostic phase staging examinations (CT scan, MRI, FDG-PET) are also involved which are necessary to multidisciplinary decision making. It can be largely infl uenced by the patient’s preference. The therapy is based on multimodality approach; surgery, radiotherapy, chemoirradiation, chemotherapy and the combination of these are used in early or locally advanced tumours. Targeted agents like EGFR inhibitors are partly used in the recurrent/metastatic setting or in combination with radiotherapy. Immun checkpoint inhibitors are new therapeutic options for pretreated, recurrent/metastatic patients and their role is under investigation in earlier therapeutic lines. Several clinical trials aim treatment desintensifi cation strategies in HPV positive tumours. Molecular genetic tests try to defi ne subgroups of patients to plan individualized treatment. Regarding the signifi cant functional and aesthetic damage of both disease and treatment, supportive care and rehabilitation are of great importance.]

[IMMUNOLOGICAL ASPECTS OF PREGNANCY FAILURES - NOVEL THERAPEUTIC APPROACHES]

FÜLÖP Vilmos

[Recurrent miscarriage and failure of in vitro fertilization and embryo transfer affect millions of women annually. It is one of the great problems of the medical community that in as many as 75% of these failures their cause is never established. Considering that recurrent abortions may have several causes including anatomical, morphological, genetic, medical, bacteriological as well as immunological abnormalities it is inevitable to pursue these kinds of examinations and tests. One part of the immunological background can be explained by autoimmune diseases while the other part of it is associated with immunopathological factors. Currently available practical testing batteries that can directly assess immunological background, as well as their importance are covered. Recently developed and mainly immunology based treatments are also described. The results generally show that immunoglobulin products can be used safely in pregnancy. In the author's institute the efficacy of this therapy has been 93.5% in cases of immune-mediated abortion. As an alternative to intravenous immunoglobulin (IVIG) therapies, partner specific platelet suspension can be used only in selected cases with proven immunological background. Therapy monitoring, that is, assessment of the functional efficacy of IVIG is possible by determining FcR blocking antibodies in the maternal serum. Based upon the functional percentage of serum blocking activity the dosage and number of treatments can be changed.]
