Lege Artis Medicinae - 2018;28(10)

[The hormesis concept contains that high doses of some substances are harmful (toxic or inhibiting), at the same time small doses of these substances are adventageous and stimulating. The pretreatment with small doses helps to neutralize the later harmful or deleterious effects of large doses and this has therapeutical (clinical) importance in case of numerous diseases and treatments. The review use two examples for demonstrating the importance of hormesis: the effect of radiation and the effect to immunity, in addition general, evolutionary aspects are also highlighted. The importance of evolutionary aspects are discussed. It demonstrates the influence of hormesis to the human evolution and calls attention to the expected changes in human diseases (as inevitable consequences of hormesis in our chemically strongly infected world), which are transmitted to the progenies. Hormesis is a therapeutic possibility as well as a challenge for medicine, this means that it is advisable to use it in the therapy and must prepare ourselves to the challenges. ]

[Juvenile idiopathic arthritis: from diagnosis to treatment]

MOSDÓSI Bernadett

[Juvenile idiopathic arthritis is a heterogeneous group of diseases that is one of the most common chronic diseases of childhood. It begins before 16 years of age, the etiology is unknown, it is persisting for at least 6 weeks and other pathologic conditions could be excluded. Juvenile idiopathic arthritis includes several diseases categories, each of them have distinct methods of presentation, clinical symptoms, pathogenesis and treatment options. Recent advances in the understanding of the immunological pathogenesis of the diseases have led to dramatic improvements in treatment. Although the management is using a multidisciplinary approach, the disease often persist into adulthood and can cause significant long-term morbidity and physical disability. Our article discusses the classification, clinical manifestations, differential diagnosis, treatment and complications of juvenile idiopathic arthritis. ]

[Gene modified T cells against cancer]

SZÖŐR Árpád

[Chimeric antigen receptor modified (CAR) T cells are hailed as a revolutionary breakthrough in the field of oncology. CAR T cells were first applied, with outstanding success, in the treatment of various leukaemias, yielding unprecedented antitumor activity and long periods of disease free survival. Following the success of CAR T cell therapy in leukaemias, solid tumors should now be targeted. These are more complex targets, therefore CAR T cell therapy needs to be further optimized for this purpose. Also, some unfortunate side effects, including the potentially deadly global inflammation called cytokine storm have to be minimized and possibly even eradicated. The next decade will be an exciting time to define whether this therapy which is yet exclusively used for cancer patients is also successful in the treatment of other diseases. In a recent study, T cells reengineered with CAR derived chimeric autoantibody receptors (CAAR) efficiently prevented disease progression in pre-clinical animal models simulating the serious autoimmune disorder, pemphigus vulgaris. Therapy was based on CAAR constructs which have the unique ability to selectively recognize and eliminate the B-cell clones secreting autoantibodies against a self-protein, thus playing a key role in disease pathogenesis and progression. In this review, we would like to give an overview about the history of the CAR T-cell concept, summarize briefly the currently running clinical trials, and discuss the challenges and future prospects of CAR T-cell therapy.]

Cholinesterase inhibitors and memantine for the treatment of Alzheimer and non-Alzheimer dementias

BALÁZS Nóra , BERECZKI Dániel, KOVÁCS Tibor

In aging societies, the morbidity and mortality of dementia is increasing at a significant rate, thereby imposing burden on healthcare, economy and the society as well. Patients’ and caregivers’ quality of life and life expectancy are greatly determined by the early diagnosis and the initiation of available symptomatic treatments. Cholinesterase inhibitors and memantine have been the cornerstones of Alzheimer’s therapy for approximately two decades and over the years, more and more experience has been gained on their use in non-Alzheimer’s dementias too. The aim of our work was to provide a comprehensive summary about the use of cholinesterase inhibitors and memantine for the treatment of Alzheimer’s and non-Alzheimers’s dementias.

[Consensus statement of the Hungarian Clinical Neurogenic Society about the therapy of adult SMA patients]

BOCZÁN Judit, KLIVÉNYI Péter, KÁLMÁN Bernadette, SZÉLL Márta, KARCAGI Veronika, ZÁDORI Dénes, MOLNÁR Mária Judit

[Background – Spinal muscular atrophy (SMA) is an autosomal recessive, progressive neuromuscular disorder resulting in a loss of lower motoneurons. Recently, new disease-modifying treatments (two drugs for splicing modification of SMN2 and one for SMN1 gene replacement) have become available. Purpose – The new drugs change the progression of SMA with neonatal and childhood onset. Increasing amount of data are available about the effects of these drugs in adult patients with SMA. In this article, we summarize the available data of new SMA therapies in adult patients. Methods – Members of the Executive Committee of the Hungarian Clinical Neurogenetic Society surveyed the literature for palliative treatments, randomized controlled trials, and retrospective and prospective studies using disease modifying therapies in adult patients with SMA. Patients – We evaluated the outcomes of studies focused on treatments of adult patients mainly with SMA II and III. In this paper, we present our consensus statement in nine points covering palliative care, technical, medical and safety considerations, patient selection, and long-term monitoring of adult patients with SMA. This consensus statement aims to support the most efficient management of adult patients with SMA, and provides information about treatment efficacy and safety to be considered during personalized therapy. It also highlights open questions needed to be answered in future. Using this recommendation in clinical practice can result in optimization of therapy.]

[The history of acute stroke care in Hungary ]

BERECZKI Dániel

[Stroke is one of the most frequent causes of death and the most important cause of permanent disability worldwide and also in Hungary. The Hungarian medical literature has mentioned this disease and has been giving recommendations for its treatment since 1690. Initially folk medicines, herbal preparations and phlebotomy were used as standard therapy. Later, cooling the head joined these methods. Pharmacy preparations emerged at the middle of the 19th century. From the middle of the 20th century, products of the pharmaceutical industry like blood flow enhancers and neuroprotective drugs were in the frontline of the acute care. Anti­hy­per­ten­sive, antithrombotic and lipid-lowering medications became part of stro­ke prevention. Imaging techniques – mainly computer tomography of the brain and ultrasound examination of the cervical large arteries – have radically changed the diagnostics of cerebrovascular diseases from the middle of the 1980s. Since the 1990s, diagnostic and therapeutic decisions are based on reliable evidence from good quality clinical trials. Since the beginning of the 21st century, reperfusion treatments (intravenous thrombolysis and mechanical thrombectomy) re­present the most effective emergency care. The current direction is the extension of the therapeutic time-window of reperfusion treatments based on sophisticated neruoimaging. This review provides a brief summary of the development of stroke care in the last three and a half centuries as reflected in the Hungarian medical literature. ]

[Hypertension, COPD and COVID-19. Focus on antihypertensive therapy]

FARSANG Csaba

[Chronic obstructive pulmonary disease is a very common comorbidity of hypertension and it is often unrecognised by physicians. The factors involved in the pathomechanism of both diseases should be realised when choosing treatment. Among factors, hypoxia, increased tone of sympathetic nervous system and activation of renin-angiotensin-aldosterone system should primarily be considered. Vascular wall damage and endothelial dysfunction has an important role in both conditions. The goals of treatment are elimination of risk factors, optimizing the blood pressure, the consequential prevention of cardio-cerebrovascular, renal and pulmonary damage; finally prolonging the patients’ life and improving their quality of life as well. Both hypertension and COPD significantly worsen the condition of COVID-19 patients since they increase the severity of the disease and the rate of in-patients’ and their mortality. In the treatment of hypertension among COPD and COVID-19 patients there must be emphasized the medication inhibiting of renin-angiotensin-aldosterone system, such as angiotensin-converting en­zyme inhibitors or angiotensin-II AT1 re­cep­tor antagonists. Special attention concerned the beneficial effect of mineralocorticoid receptor antagonist spironolactone. Other antihypertensive drugs (calcium channel blockers, thiazide-like diu­retics, high selectivity β1 receptor antagonists) may supplement the treatment if necessary. Long-acting β2 receptor agonists, muscarinic receptor antagonists and inhalation corticosteroids may be administered in double or triple combination also in hypertension and COPD as well. It is important to note, that statin therapy and also vitamin D3 improve the condition of COVID-19 patients.]

Surveillance and management of patients with tuberous sclerosis complex

FOGARASI András, GYORSOK Zsuzsanna, BODÓ Tímea

Tuberous sclerosis complex (TSC) is an autosomal dominant disease due to the uncontrolled differentiation, proliferation, and migration of cells in several organs. Clinical expression is highly variable, from mild skin findings and asymptomatic brain lesions to seizures, mental retardation, autism, and potentially fatal kidney, cardiac, or pulmonary disease. Aim of this paper is to summarize the diagnostic criteria, surveillance and therapeutic issues of this multisystemic disorder emphasizing the most important neurological consequences. Presenting the state-of-the-art management recommendations and comparing them with the local protocols, we hope that our review might help in the proper assessment of one of the most important single gene disorder.
