[Beyond the blood sugar reduction. SGLT-2 inhibitors in kidney protection]

SIMONYI Gábor

[Results of cardiovascular safety studies with SGLT-2 inhibitors have shown that in addition to their hypoglycaemic and beneficial cardiovascular effects, they are renoprotective. A number of mechanisms underlying the renoprotective effects of SGLT-2 inhibitors have been shown to reduce albuminuria and deterioration of renal function. Their nephroprotective effects extend over a very wide range of eGFR and albuminuria categories. In the DAPA-CKD study, dapagliflozin was shown to exert its nephroprotective effect regardless of the presence of diabetes and a baseline eGFR, while also having a beneficial effect on cardiovascular endpoints and mortality. Following the confirmation of favourable renal results for SGLT-2 inhibitors, it is no coincidence that they have been included in national and international recommendations for the treatment of chronic kidney disease.]

[Telmisartan plus amlodipine single-pill combination therapy to achieve blood pressure goal values in hypertensive patients treated by general practitioners – an observational study]

ÁMON Tamás, BARACSI-BOTOS Viktória, MÉSZÁROS Ágota, JÁRAI Zoltán

[Background: Current European guidelines on the management of hypertension suggests a simple and easily applicable therapeutic strategy to increase effectiveness. Important component of this strategy is the application of single-pill combination (SPC) of RAS inhibitor in combination with calcium antagonists or diuretics as a first step. Primary objective: To assess the percentage of patients reached goal blood pressure ranges after 12 weeks of fix dose combination therapy with telmisartan plus amlodipine according to office blood pressure measurements in hypertensive patients treated by general practitioners (GPs). Patients and methods: After informed consent, 729 patients of 63 GP’s office participated in this multicentre, non-interventional, prospective data collection study. The intention-to-treat (ITT) population was 717, and primary endpoint was analysed in 690 patients (per protocol [PP] population). There were two visits during the study. Blood pressure was measured in all patients at the time of the enrollment and at the second and final visit. Results: The average age of the patients was 62±12 years, 55% of the patients were younger than 65 years, 357 patients (49.8%) of the population was male. The average office blood pressure at baseline was 150±17/88±10 mmHg, and decreased to 130±8.1/78±6.1 mmHg at 12 week (p<0.05). Pulse rate has decreased as well (from 80±9.8 /min to 75±6.3/min). At baseline 10.1% of the patients were at optimal systolic blood pressure goal, 15.8% at optimal diastolic blood pressure goal and only 5.5% simultaneously at systolic and diastolic goal. By the end of the observational period the percentage of patients reached optimal BP goal values increased to 51.6%, 54.1% and 33.0%, respectively (systolic, diastolic, systolic and diastolic). Also the proportion of those who achieved primary target BP below 140/90 mmHg was higher. At baseline 19.2% of patients had BP below 140/90 mmHg, which increased to 87.1% by the end of the study. Patients tolerated SPC telmisartan/amlodipine well, 95% of the patients continued to receive prescribed medication after study conclusion. Conclusion: These real world data shows that the introduction of a fix dose combination therapy after free combination therapy increases the success rate of treatment during a relative short period, however many of the patients would still need higher doses or additional therapy after 3 months in order to achieve the optimal BP target levels. ]

[Dialysis service in coronavirus pandemic]

SZEGEDI János, HORN Péter, GERGELY László, TÖLGYESI Katalin, MOLNÁR Gergely

[The coronavirus pandemic started at December 2019 from Wuhan. The rate of spread of the coronavirus epidemic has shocked the entire world, and the WHO declared it as a pandemic in March 2020. The first case in Hungary was confirmed in March 2020. The infection primarily damages the lungs but can also infect other organs. The relationship between coronavirus infection and the kidney is bidirectional. On the one hand, the infection can cause acute renal damage, and on the other hand, chronic kidney patients and patients receiving renal replacement therapy are at increased risk of infection due to their immune compromised status. Chronic kidney patients are three times more likely to have a severe Covid-19 infection than the general population. Among patients with severe Covid-19, the incidence of acute renal failure may exceed. Patients treated with the HD program have a higher risk of infection due to transportation and treatment in the common area. The mortality rate of Covid-19 infected patients receiving renal replacement therapy is 20-35% according to international data. Infections occured in all the dialysis centers of the B.Braun Avitum Dialysis Network during both the 2nd and 3rd wave of the epidemic. Epidemiological data confirm that preventive measures are of paramount importance in the field of prevention of infections and in the care of the pandemic. Effective prevention and patient care can only be ensured on the basis of correct epidemiological data. The management of the B.Braun Avitum Dialysis Network decided at the time of the outbreak in Hungary to establish an Operational Staff to perform tasks related to the epidemic. The tasks of the Operational Staff are the following: to ensure an effective, up-to-date connection with the dialysis centers, to update the epidemiological data, and to develop and operate an effective prevention program and action plan. To address the epidemic situation, complex measures were introduced in the Network regulated in a pandemic plan which was periodically reviewed. This document includes detailed hygiene regulations regarding patient transport, screening of dialysis center entrants, proper use of mask and personal protective equipment, hand hygiene, contact and respiratory isolation, rules of behavior, ordering a visitation ban, and regulation of cooperation with the hospital. ]

[Dialyzed patients with Covid-19 infection in Hungary in 2020]

KULCSÁR Imre

[We have observed the number and mortality of dialyzed patients with Covid-19 infection in 2020 in Hungary. We have summarized all of 54 dialysis facility where adult patients were treated. During the year, 1242 cases of infection were confirmed in patients undergoing dialysis. 16% (753/4704) of incident dialysis patients were infected. The number of dialysis patients with all Covid-19 infections was 1995. 31.1% of infected patients have died. The mortality was higher in large hemodialysis centers (patient transport, isolation difficulties, increased risk of contamination). Covid-19 positive patients treated with peritoneal dialysis (PD) had significantly lower mortality than those treated with hemodialysis (HD). Chronic kidney disease (CKD) is the most common risk factor for serious Covid-19 infections worldwide, which is why these patients require increased attention (especially for dialysis and transplant recipients). In 2020, there was no vaccine available in our country]

[Metabolic effects of cardiovascular drugs]

FÜLÖP Tibor

[Cardiovascular drugs are used for the treatment and primary and secondary prevention of diseases affecting the cardiovascular system. Like all drugs, these drugs may have pharmacological effects in addition to their therapeutic effects. Of particular importance are the effects that affect, have a positive or negative effect on global or cardiac metabolism. In addition to primary cardiovascular diseases, most cardiovascular diseases are strongly influenced by patient’s metabolic status and adaptation to the disease itself. Drugs that affect global and cardiovascular metabolism, in addition to their recognized main mechanism of action, may be of particular interest, both because of their potential beneficial and detrimental effects, especially in the long run, as these drugs are most likely to be taken by our patients for the rest of their lives. These effects should be known to physicians treating patients with cardiovascular disease, and their therapeutic decisions should be made by this knowledge. This article is intended to assist in this decision making by reviewing the metabolic effects of major cardiovascular drugs.]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

Alexithymia is associated with cognitive impairment in patients with Parkinson’s disease

SENGUL Yildizhan, KOCAK Müge, CORAKCI Zeynep, SENGUL Serdar Hakan, USTUN Ismet

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.

[The connection between the socioeconomic status and stroke in Budapest]

VASTAGH Ildikó, SZŐCS Ildikó, OBERFRANK Ferenc, AJTAY András, BERECZKI Dániel

[The well-known gap bet­ween stroke mortality of Eastern and Western Euro­pean countries may reflect the effect of socioeconomic diffe­rences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomi­cally deprived neighborhoods. ]

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]
