[New era of anticoagulation]

LOSONCZY Hajna

[Two types of anticogulants have been introduced into the clinical practice and used succesfully for more than 60 years: the heparins and the cumarins. Blood coagulation is targeted by the two drugs on many sites, their inhibitory action is not specific. The hirudins as specific trombin inhibitors have been introduced later for specific indications. After the discovery of the exact structure of the clotting factors, the drug development could have been directed against its active center which made possible the development of more specific anticoagulants. Some attributes of an ideal anticoagulants: sufficient efficacy with safe administration, predictable therapeutic effect with fixed dosing, no need for monitoring, oral administration, to have a specific antidote, no food or drug interactions. New anticoagulants are inhibitors of the initiation of blood coagulation. Tissue factor pathway inhibitors; inhibitors of the propagation of clotting process: activated protein C; indirect factor Xa inhibitors (requiering antithrombin to its actions: pentasaccharide, idrabiotaparinux and ultra-low-molecular weight heparins); direct FXa inhibitors, acting without antithrombin: rivaroxaban and apixaban; and out of the direct oral thrombin inhibitors acting against fibrin-formation, dabigatran-etexilate are discussed.]

Delirium is a syndrome frequently encountered in intensive care and associated with a poor prognosis. Intensive care delirium is mostly based on general and palliative intensive care data in the literature. In this study, we aimed to investigate the incidence of delirium in coronary intensive care unit (CICU), related factors, its relationship with inhospital and follow up prognosis, incidence of age-related delirium and its effect on outcomes. This study was conducted with patients hospitalized in CICU of a tertiary university hospital between 01 August 2017 and 01 August 2018. Files of all patients were examined in details, and demographic, clinic and laboratory parameters were recorded. Patients confirmed with psychiatry consultation were included in the groups of patients who developed delirium. Patients were divided into groups with and without delirium developed, and baseline features, inhospital and follow up prognoses were investigated. In addition, patients were divided into four groups as <65 years old, 65-75 yo, 75-84 yo and> 85 yo, and the incidence of delirium, related factors and prognoses were compared among these groups. A total of 1108 patients (mean age: 64.4 ± 13.9 years; 66% men) who were followed in the intensive care unit with variable indications were included in the study. Of all patients 11.1% developed delirium in the CICU. Patients who developed delirium were older, comorbidities were more frequent, and these patients showed increased inflammation findings, and significant increase in inhospital mortality compared to those who did not develop delirium (p<0.05). At median 9-month follow up period, rehospitalization, reinfarction, cognitive dysfunction, initiation of psychiatric therapy and mortality were significantly higher in the delirium group (p<0.05). When patients who developed delirium were divided into four groups by age and analyzed, incidence of delirium and mortality rate in delirium group were significantly increased by age (p<0.05). Development of delirium in coronary intensive care unit is associated with increased inhospital and follow up morbidity and mortality. Delirium is more commonly seen in geriatric patients and those with comorbidity, and is associated with a poorer prognosis. High-risk patients should be more carefully monitored for the risk of delirium.

[Do previous offences predict violent acts in psychiatric patients? A retrospective study in Hungary]

BARAN Brigitta, SZABÓ Ádám Ferenc, KARA Borbála, KOVÁCS Magdolna, UZONYI Adél, ANTAL Albert, UNGVARI S Gabor, GAZDAG Gábor

[Aim - To investigate the presence of offences in the previous past history of perpetrators of violent acts who have undergone forced medical treatment. Methods - The documentation of all patients released over a 10-year period from the National Institute of Forensic Psychiatry (IMEI) was reviewed. A comparison was drawn between patients who were convicted of any type of offense before the violent act (patients with previous offences-PPO) and those who were not (patients with no previous offences-PNO). Results - Eighty-six (29%) and 208 (71%) patients formed the PPO and PNO groups, respectively. Prior contact with psychiatric services was significantly higher in the PPO group (p=0.038) and this group was also more likely to offend under the influence of a psychoactive substance (p<0.001). Exceptional brutality and other qualifying factors were more frequent in the PNO group (p=0.019). Conclusion - As IMEI is the only forensic institution in Hungary, the picture presented here reflects the situation in the entire country. A recidivism rate of 29% is within the internationally published range. ]

[FREQUENCY OF DIFFERENT FORMS OF DEMENTIA IN THE DEPARTMENT OF NEUROPATHOLOGY OF THE HUNGARIAN NATIONAL INSTITUTE OF PSYCHIATRY AND NEUROLOGY DURING A 3-YEAR PERIOD]

KOVÁCS Gábor Géza, KŐVÁRI Viktor, NAGY Zoltán

[Background - Dementia is an increasing problem of the society. The underlying cause of dementia may be difficult to diagnose during life. Only neuropathological examination gives definite diagnosis. Differences in the reported frequency may be related to factors such as the age or gender of subjects with dementia. Materials and methods - In our neuropathology-based study we examined 156 consecutive subjects clinically diagnosed with dementia during a 3-year period. Using histopathological criteria we calculated the frequencies of various disorders causing dementia. We studied the effect of age and gender on these frequencies. Results - Alzheimer’s disease was the most frequent pathologic finding (57.7%) followed by vascular dementia (43%); diffuse Lewy body disease (15.4%); argyrophilic grain dementia (12.1%), various forms of frontotemporal dementia (5.7%); and other (4.5%). The latter comprise prion disease, alcoholic encephalopathy, and hippocampal sclerosis. Mixed pathology was common: concomitant Alzheimer’s disease was present in 41.6% of diffuse Lewy body disease cases and in 49.2% of vascular dementia patients. Pure disease forms are rare: Alzheimer’s disease: 26.3%, vascular dementia: 17.3%, diffuse Lewy body disease: 5.1%, argyrophilic grain dementia: 2.5%. Females were overrepresented among those with Alzheimer’s disease with age at death above 75 years (p <0.02), while males were overrepresented in patients below 75 years with vascular dementia (p <0.05). Conclusions - Our study indicates that the frequency of neurodegenerative dementias is high in the examined patients, but vascular pathology frequently influences the clinical course.]

[Clinical pharmacologic principles and problems related to the clinical use of innovative and similar biological medicines]

KERPEL-FRONIUS Sándor

[The active substances in the biological medicinal products are macromolecules, primarily proteins most of which are currently produced by various biotechnological methods in different biological systems. The spatial structure of the macromolecular active substances cannot be accurately determined by the presently available methods. Therefore, both physico-chemical and biological methods are needed for the control of their quality and production. The active proteins induce immunologic reactions in the organism. The appearance of neutralizing antibodies frequently leads to the inhibition of the effect of the biological medicines. The European Medicines Agency (EMA) registers the medicinal products containing similar macromolecular active substances produced by biotechnological methods as biosimilar agents, since their chemical identity cannot be proven. The similarities and differences of their biological and immunological effects can be evaluated only in comparative non-clinical and clinical trials. The frequent exchange of biological medicines increases the appearance of antibodies in the patients, therefore the substitution of biological drugs should be done only by the treating physicians if clinically necessary.]
