[Various medical associations issue different recommendations for the prevention and treatment of vitamin D deficiency. These significant differences are partly explained by the different definition of normal vitamin D level and the use of completely different mathematical models to predict the increase in vitamin D level as a response to therapy. According to the Institute of Medicine (IOM), the target vitamin D level is 20 ng/ml, whereas the Endocrine Society (ES) recommends 30 ng/m as the miminum target value. According to the ES, a 1 ng/ml increase of vitamin D level can be reached by a daily intake of 100 NE, while the IOM recommends 3.6 ng/ml. Moreover, the IOM states that the effect of therapy on serum level is nonlinear. These differences show that the ES and IOM have different views on the risk of adverse effects. The IOM recommends 400 IU vitamin D daily for children younger than 1 year, 800 IU for those above 70 years and 600 IU/per day for everyone else. The ES recommend 400-1000 IU daily for all infants and 1500- 2000 IU for adults. Screening, however, is not recommended by either society. To decrease uncertainty concerning the side effects of higher-dose vitamin D treatment, it is important to understand, use and support the function of the pharmacovigilance system of the pharmaceutical industry that manufactures and markets various (prescription, over-the-counter) preparations. This is what the author aims to highlight in the second part of this article. Using this system, both the doctor and the patient can help support and accept the justification of higher-dose vitamin D therapy.]

[Statins have become crucial components of the therapy of cardiovascular diseases. Beyond their cholesterol-lowering effect, statins turned out to have further beneficial effects on various vascular mechanisms. One of the best known effects is antithrombotic capacity, which is related partly to platelet function and partly to the coagulation cascade. Besides experimental observations, interventional clinical trials have also demonstrated that statins have an antithrombotic effect both in arterial and venous thrombosis. Regarding the effects of statins on dementia, previous studies with relatively small sample sizes had controversial results. Recently, two observational studies of tens of thousands of elderly patients reported that statins reduce the incidence of nonvascular dementia. Evaluation of the data revealed that statins have pleiotropic effects in this case, too. The results discussed here shed light on new benefits of statin therapy used for reducing cardiovascular mortality, namely the prevention of thrombotic events and dementia. These benefits are related to the antithrombotic and anti-inflammatoric capacity of statins.]

[Role of β-blockers, especially carvedilol in the treatment of hypertension]

PÁLL Dénes, MARODA László, ZRÍNYI Miklós

[Changes in hypertension guidelines in the past years have affected the clinical thinking about β-blockers. Authors reviewed the development of β-blockers emphasizing the differences across various active pharmaceutical agents. Different hemodynamic and metabolic effects are being discussed in details for the third ge - neration vasodilatator carvedilol. Carvedilol has no effect on cardiac output but decreases peripheral vascular resistance which results in lower blood pressure values. However, carvedilol, opposite to unfavorable effects of traditional β-blockers, has a neutral impact on both carbohydrate and lipid metabolisms. Its more advanced cardiac effects include decreased left ventricular hypertrophy and increased coronary flow reserve. Vasodilatator type β-blockers (carvedilol, nebivolol) are indicated in the combi - nation treatment of hypertension, especially when the patient has heart failure, coronary disease or suffered from a previous heart attack.]

[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]

[Novelties in the management of Hodgkin lymphoma]


[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.]

[Dizziness - vertigo Warning symptoms in vertebrobasilar ischemia - Part I. ]


[Dizziness and vertigo - like headache - are the most common complaints which leads patients to visit the doctor. In spite of the headache - which may be primary (e.g. migraine) or symptomatic - dizziness and vertigo do not appear to be a separate nosologic entity but rather the symptoms of several neurological disorders. For differential diagnosis, interdisciplinary thinking and activity is needed because the vestibular, neurological and psychiatric disorders might have a common role in the development of symptoms and further overlapping can also occur. The vascular disorders of the vertebrobasilar system are discussed in detail in this review. The importance, occurrence and causes of vertigo as a warning symptom is in the focus. The author draws attention to life-threatening conditions with acute onset in cases of the posterior scale ischemia and emphasizes the importance of the correct and early diagnosis. The author tries to clear up the nihilistic aspect in treating of stroke and stresses the necessity of thrombolysis and interventional radiological procedures which may be the only chance for the recovery of the patients. The pharmacological prevention of recurrent vascular events is also important and obligatory for the clinicians.]

Physical activity as primary prevention of metabolic syndrome


Metabolic syndrome is constantly discussed, together with cancer diseases, as one of the biggest threats to the 21st century. Despite the differing indicators of specific diseases behind the metabolic syndrome, it is to be understood as a very risky aspect of health. Primary prevention through life style modifications, specifically reduction of the sedentary way of life and integration of regular physical activity into daily life of children, adults and seniors is an appropriate tool of prevention of metabolic syndrome. A number of valid studies show that increasing physical motion contributes to improvement of diseases that stand behind the metabolic syndrome. However, healthy adult population of the Czech Republic shows distinctive dislike of physical activity and primary prevention is insufficiently supported both by experts dealing with this issue and at political level while secondary prevention prevails. Therefore we consider it imperative to involve more funding into programs supporting physical activity. It is also necessary to explore forms of education within the physically active life style.
