[SARS-CoV-2 virus infection sprang from Wuhan the capital of the Chinese Hubei province, at the end of 2019 and caused a worldwide pandemic with 1.5 million confirmed cases and claimed almost 100 000 victims until the beginning of April, 2020. First analyses of Chinese COVID-patients confirmed that diabetes, hypertension, and cardiovascular diseases were highly prevalent among SARS-CoV2 infected patients, and might be associated with poor outcome. As previously shown for SARS-CoV-1, SARS-CoV-2 similarly utilizes ACE2 as receptor for viral alveolar cell entry. A suspicion has arisen that the widely used ACE-inhibitor/ARB therapy could be potentially harmful for patients suffering from COVID-19 infection as these agents upregulate the ACE2-expressions. From the other point RAAS-blockade might be beneficial due to fact that ACE2 counters the deleterious effects of Angiotensin II. Authors provide a comprehensive over­view of the most recent literature and summarize the link between COVID-19 and car­diovascular disease. It is important to em­phasize that there are no available hu­man evidences confirming if the RAAS-in­hi­bitor therapy were harmful or helpful in pa­tients suffering from COVID-19.]

[Digitally-assisted treatment planning in precision oncology]

PETÁK István, VÁLYI-NAGY István

[The progress of molecular information based on personalized precision medicine has reached a new milestone. Actually, about 6 million mutations of 600 genes may be related to the development of cancer, and on average, 3-4 of these “driver” mutations are present in each patient. Due to the progress in molecular diagnostics, we can now routinely identify the molecular profile of tumors in clinical settings. By clinical translation, there are actually available more than 125 targeted pharmaceuticals and hundreds of such therapies are under clinical trial. As a result, we have many first-line and licenced treatment options to be elected by molecular information as the optimal one for every patient. There is an increasing need for complex informatics solutions by medical software. Geneticists, molecular biologists, molecular pathologists, molecular pharmacologists are already using bioinformatics and interpretation software on their daily work. Today, online digital tools of artificial intelligence are also available for physicians for assisted treatment planning. Telemedicine, videoconferencing provide solutions for interdisciplinary virtual molecular tumor boards, which democratizes the access to precision oncology for all doctors and patients. ]

[Case report about the choice of care at Olajág Elderly Home in Budapest during the COVID-19 epidemic in spring 2020]

PETRÓ Kata, PETKE Zsolt, RADNAI Zoltán, SZIRMAI Viktor

[During the COVID-19 pandemic caused by the SARS-CoV-2 virus, elderly people in long-term nursing homes were espe­cially risks exposed. In this study, the au­thors analyse the causes of local outbreak at the Olajág Elderly Home Vezér street facility in Budapest and the means and ways to curb the spreading of infection. They summarise the measures, which proved to be effective in isolation and treat­ing the patients. The number of infected residents as well as the course of the disease are demonstrated by statistical data. The authors consider as pre-eminently important to identify asymptomatic but in­fec­ted residents, further the rapid introduc­tion of screening tests, strict compliance with protocols, patient path regulation and the use of enhanced, supportive communication.]

[The significance of generic valsartan in the treatment of patients]

VÉRTES András

[The renin-angiotensin-aldosterone system (RAAS) is involved in the regulation of electrolyte and water balance primarily; however, it also influences vascular function and increases blood pressure - especially under pathological conditions. Hypertension, post-myocardial infarction state, and heart failure are, for example, associated with excessive systemic and/or local activation of the RAAS. Angiotensin II (AT-II) generated by the latter contributes - along with additional factors and through its deleterious effects (vasoconstriction, endothelial dysfunction, atherosclerosis, prothrombotic state, fibrosis, etc.) - to damage to the target organs involved in the sequence of cardiovascular events. Inhibiting the RAAS at different levels is of therapeutic importance - its purpose is to delay disease progression, to prevent end organ damage, and to achieve a better outcome. As AT-II acts on several (AT1 and AT2) receptors, using angiotensin receptor blocking (ARB) agents with a high selectivity for the AT1 receptor is the rational choice. In view of its favourable therapeutic properties and efficacy demonstrated by morbidity and mortality studies, a generic formulation of appropriate quality, containing valsartan as active substance could prove to be the ideal treatment for patients with hypertension and other cardiovascular disorders.]

[Covid-19 and the kidney]

PATÓ Éva, DEÁK György

[Covid-19 pandemy has emerged from Wuhan, China in December 2019. The infection affects not only the lung but other organs such as the kidney, as well. The relation between Covid-19 infection and the kidney is bidirectional. On one hand, Covid-19 infection may cause kidney damage in 50-75% of the cases resulting in proteinuria, haematuria and acute kidney injury (AKI). The etiology of AKI is multifactorial. Main pathogenic mechanisms are direct proximal tubular cell damage, sepsis-related haemodinamic derangement, citokine storm and hypercoagulability. The virus enters proximal tubular cells and podocytes via the ACE2 receptor followed by multiplication in the lysomes and consequential cell lesion. Histopathology shows acute tubular necrosis and acute tubulointerstitial nephritis. AKI is a strong predictor of mortality in critically ill patients. On the other hand, the risk of Covid-19 infection and mortality is substantially increased in patients with chronic kidney disease – especially in those with a kidney transplant or on dialysis – due to their immunocompromised status. Among haemodialysis patients, infection may spread very easily due to the possibility of getting contacted in the ambulance car or at the dialysis unit. The mortality rate of patients on renal replacement therapy with Covid-19 infection is 20-35%. In order to avoid mass infection it is obligatory to employ preventive measures and implement restricions along with (cohors) isolation of infected patients. In Hungary, every dialysis or kidney transplant patient with Covid-19 infection should be admitted to dedicated Covid-19 wards.]

[Neurological aspects of the COVID-19 pandemic caused by the SARS-CoV-2 coronavirus]

BERECZKI Dániel, STANG Rita, BÖJTI Péter, KOVÁCS Tibor

[By the spring of 2020 the COVID-19 outbreak caused by the new SARS-CoV-2 coronavirus has become a pandemic, requiring fast and efficient reaction from societies and health care systems all over the world. Fever, coughing and dyspnea are considered the major signs of COVID-19. In addition to the involvement of the respiratory system, the infection may result in other symptoms and signs as well. Based on reports to date, neurological signs or symptoms appear in 30-50% of hospitalized COVID-19 patients, with higher incidence in those with more severe disease. Classical acute neurological syndromes have also been reported to associate with COVID-19. A drop in the volume of services for other acute diseases has been described in countries with healthcare systems focusing on COVID-19. During the COVID-19 epidemic it is also important to provide appropriate continuous care for those with chronic neurological disorders. It will be the task of the future to estimate the collateral damage caused by the COVID-19 epidemic on the outcome of other neurological disorders, and to screen for the possible late neurological complications of the SARS-CoV-2 coronavirus infection.]
