[The advantages of a fixed combination of lisinopril with amlodipine in patients with primary hypertension]

GAHRAMANOVA SM, BAKHSHALIYEV AB

[Background: The aim of the study was to examine the effect of amlodipine, lisinopril and a fixed low-dose combination of amlodipine + lisinopril on the performance of the daily profile, blood pressure variability and heart rate variability in patients with PH stage I-II, 1-2 degrees. The diagnosis of PH was made in accordance with the classification of JNC USA in 2003, ESH, ESH 2007 on the basis of careful clinical and instrumental investigations. Methods: The study included 75 PH patients who were divided into three groups depending on the medication received. The first group included 23 patients treated with lisinopril, the second included 27 patients treated with amlodipine, and the third included 25 patients receiving a fixed combination of amlodipine + lisinopril. Drugs were administered once daily with dose titration for lisinopril effective for 10 to 20 mg (mean 15.6±2.2 mg), for amlodipine 5 to 10 mg (mean 7.8±1.1 mg), and Lisonorm administered in a standard fixed dose (lisinopril 10 mg, amlodipine 5 mg), once in the morning. Controlled treatment lasted for 12 weeks. The study used daily blood pressure monitoring and ECG Holter monitoring methods. Results: A comparison of side effects found that combined therapy significantly reduced the number of adverse reactions. For all three groups, treatment resulted in a significant decrease in the average daily, daytime and night-time BP values and in the variability of systolic and diastolic BP. With combined therapy, these changes were more significant. Conclusion: These positive changes appear to be due to the fact that combination therapy can affect several parts of the pathogenetic development of hypertension, compared with the effects of monotherapy, with superior results. In the combination therapy, lisinopril levelled the sympathetic stimulation of amlodipine by blocking the activity of the sympathoadrenal and renin-angiotensin-aldosterone system.]

[The importance of white-coat hypertension in adolescents]

LENGYEL Szabolcs, SZÁNTÓ Ildikó, KATONA Éva, PARAGH György, FÜLESDI Béla, PÁLL Dénes

[The importance of adolescent hypertension is that there is tight correlation between blood pressure data in adolescents and in adulthood. In case of sustained adolescent hypertension increase of the left ventricular mass and the intima-media thickness of the carotid artery is also detected. The prevalence of adolescent hypertension is about 1-4%. Among them 1-41% is the frequency of white-coat hypertension. Diagnosis can be set up with repeated measurements at home, or with ambulatory blood pressure monitoring. In the background of adolescent white-coat hypertension the increased sympathetic activity has outstanding importance, which causes endothel dysfunction and increased arterial stiffness. There are growing evidence, that adolescent white coat hypertension is not a harmless condition, because sustained hypertension can develop in the future. In its case risk survey, start of non-pharmacological treatment, and follow-up has major importance.]

[THE POSSIBILITIES OF USING PROBIOTICS IN DIGESTIVE DISEASES]

DEMETER Pál

[The mammalian intestinal tract contains a complex, dynamic and diverse society of microorganisms. The beneficial effects of developing a normal bacterial flora are: colonic resistance against pathogens, immunmodulation and intact intestinal barrier. Probiotics are live microbial supplements which beneficially affect the host by improving its intestinal microbial balance after oral administration. The health benefits of probiotics have been the subject of increased research interests. This paper gives a review of the literature that study the roles of probiotics in the prevention and treatment of antibiotic-associated diarrhea, traveller's diarrhea, irritable bowel syndrome, inflammatory bowel disease, Helicobacter pylori infection and hepatic encephalopathy. In human studies the examined probiotics are safe, tolerable and seem to be effective in conditions of diarrhea caused by antibiotics, traveller's diarrhea and pouchitis. In other above-mentioned conditions further randomized and controlled clinical trials are needed to evaluate their efficacy. Based on these results, in the research and manufacturing of genetically-engineered probiotic bacteria a major leap is expected.]

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.

[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.]
