[Hepatitis B virus infection is a significant health problem worldwide, as well as in Hungary. The chronic infection is usually symptomless, its most dangerous risks are liver cirrhosis and hepatocellular carcinoma. The latter may occur without development of liver cirrhosis, so it means a potential complication for patients with inactive phase of infection, as well. Criteria of the indication of antiviral treatment have changed in the last years due to the flare of our knowledge about the natural history of the disease. In our days quantitative determination of hepatitis B viral nucleic acid titer is essential for diagnosis. Formerly, a HBsAg positive patient with normal liver enzymes had been regarded as inactive carrier, and antiviral treatment had not been advised. In our days, the phase of the infection and the necessity of the treatment can not be determined without measurement of nucleic acid titer. Liver biopsy and, if inflammation or fibrosis is present, antiviral treatment is indicated, if the nucleic acid titer is >20 000 IU/ml in HBeAg positive, and >2000 IU/ml in HBe negative cases, respectively. Interferon alpha is the gold standard of treatment for chronic B hepatitis. Pegylated interferon alpha-2a is used because of its better pharmacokinetic properties. Oral agents include nucleoside/ nucleotide analogues with rare and mild adverse effects, and they may be given to patients with decompensated liver disease. Their main disadvantages include the development of drug-resistance, and the very low ratio of HBsAg-anti-HBs seroconversion. Recent drugs like adefovir, entecavir and tenofovir have replaced lamivudin, which has been in use for the longest time, because they are more effective and resistance against them is less frequent.]

[Medicinal preparations with durable analgetic effect are essential for therapy of the chronic pain. Controlling drug release allows the influence of fate of drug in the body as well as prolongation of duration of action. Development of innovative dosage forms as drug delivery systems offers increased efficacy and tolerability to improve patient's quality of life. Beside maintaining continuous therapeutical effect, extended drug release allows the spacing of dosing frequency. In addition, the more advantageous dosage regimen may improve the patient compliance during drug therapy. The review focuses on the aspects required to design drug carrier systems with original pharmacokinetic profile based on special pharmaceutical technological methods in order to optimize drug therapy for pain management.]

Investigation of risk factors, topographic location and stroke mechanisms of unilateral isolated and posterior cerebral ARTERY thalamic infarcts

GÖKCAL Elif, SENGUL Yildizhan, USLU Ilgen Ferda

Aim - In this study, we aimed to examine the risk factors, topographic features and stroke mechanisms of acute ischemic unilateral infarcts of thalamus. Methods - Patient with isolated thalamic infarct and those with posterior cerebral artery (PCA) infarction who were admitted to our hospital between January 2014 and January 2017 with acute unilateral thalamic infarction (TI) were included in this study (isolated thalamic infarction/ isolated TI; thalamic and posterior cerebral artery infarction/PCA+TI). Demographic characteristics and vascular risk factors of the patients were determined. Thalamic infarct areas were recorded topographically as anterior, posteromedial, ventrolateral, posterolateral, more than one area, and variant areas. Stroke mechanism was determined according to the criteria of „Trial of Org 10172 in Acute Stroke Treatment” (TOAST). Patients with isolated TI and PCA TI were compared according to risk factors, stroke mechanism and infarct topography. Results - Forty-three patients with a mean age of 63.3 ± 14.5 years were included in the study. Twenty-eight patients (60.1%) were found to have isolated TI and the remaining 15 patients (34.9%) had PCA+TI. 32.1% of patients with isolated TI had sensory symptoms on presentation, and 60% of patients with PCA-TI had sensorimotor symptoms. The mean age, the mean score on National Institutes of Health Stroke Scale (NIHSS) and the mean frequency of atrial fibrillation were higher in PCA+TI patients than in isolated-TI patients (p: 0.04, p: 0.004, p: 0.02 respectively). 32.6% of the patients had ventrolateral, 30.2% had posteromedial involvement. Ventrolateral topography was seen in 46.7% of the PCA+TI patients, while posteromedial topography was seen in 39.3% of the isolated-TI patients. 53.6% of the isolated-TI had small vessel disease etiology, while 40% of the PCA+TI had cardioembolic etiology, and the other 40% had large artery atherosclerosis. Conclusion - Our study showed that the most ommon stroke mechanism in patients with thalamic infarction is the small vessel disease. Isolated TI and PCA+TI patients differ in terms of etiologic mechanism and infarct topography. Variant territorial involvement and multiple area involvements can be quite common in thalamic infarcts.

[Is there a role of triple combination in the therapy of hypertension? - Antihypertensive efficiency of perindopril-amlodipine-indapamide]

PÁLL Dénes, SZÁNTÓ Ildikó, PARAGH György, KATONA Éva

[Blood pressure reduction to target level decreases cardiovascular morbidity and mortality. However, in the vast majority of cases, this can be achieved only with a (multiple) combination regimen. The primary objective of the PAINT (Perindopril- Amlodipine plus Indapamide Combination for Controlled Hypertension Non-intervention Trial) study was to evaluate the efficacy of combination therapy with perindopril, amlodipine, and indapamide in patients who had not reached target blood pressure with their pre-existing therapy. Secondary objectives included the monitoring of metabolic parameters and the number of antihypertensive tablets taken by the subjects. In this subgroup-analysis we involved 126 patients (74 females and 52 males, mean age 59.8±12.5 years) who had a valid 24-hour ambulatory blood pressure monitoring both at baseline and at the end of the 4-months follow-up. At the beginning of the study none of the subjects reached blood pressure target despite taking on average 2.4±1.4 antihypertensive drugs. During the study, the subjects received the combination of amlodipine, perindopril, and indapamide instead of their pre-existing antihypertensive regimen. 24-hour mean systolic blood pressure decreased from 139.2±13.4 mmHg to 126.5±12.9 mmHg (p<0.01), as well as mean diastolic blood pressure from 77.3±11.3 mmHg to 71.1±8.7 mmHg (p<0.01). Heart rate remained unchanged. Blood pressure reduction was statistically significant both during the day and the night. We found significant blood pressure reduction in all hours (10.1-15.4/5.1-7.8 mmHg; p<0.001). Hyperbaric impact decreased from 366.9±251.1 mmHg × hour to 166.2±185.4 mmHg × hour (p<0.01) for systolic blood pressure, and from 112±130.6 mmHg × hour to 41.6±65.6 mmHg × hour (p<0.01) for diastolic blood pressure. We also could observe favourable changes in metabolic parameters, not only in lipids, but also in blood sugar level. The mean number of tablets taken by the subjects increased from 2.4 to 2.9, but this led to a significantly improved control of blood pressure. Triple combinations of state-of-the-art antihypertensive agents - such as of perindopril, amlodipine and indapamide - ensure effective blood pressure control in sufficiently compliant patients.]

[Background - Bilateral pallidal deep brain stimulation (DBS) is an established treatment option for primary generalized and segmental dystonia. In the present study we evaluated the results of our dystonia patients treated by DBS. Methods - The surgical results of forty consecutive dystonia patients underwent DBS implantation were analyzed (age: 43.7±17.7 years; sex: 22 men; etiology: 24 primary and 16 secondary dystonia; topography: 24 generalized, 12 segmental and four hemidystonia; disease duration: 16.1±9.3 years). Severity of dystonia measured by Burke-Fahn-Marsden Dystonia Rating Scale (BFMDRS) and health-related quality of life measured by EQ-5D scale were obtained preoperatively and compared to the scores obtained at postoperative six months and subsequent yearly follow-ups. The average follow-up lasted 2.5 years (median, 0.5-8 years). In all cases the BFMDRS scores were re-evaluated by a rater blinded to the treatment. Treatment responsiveness was defined as an at least 25% improvement on the BFMDRS scores. Non-parametric Mann-Whitney, McNemar and Kruskal-Wallis tests were applied to test statistical significance. Results - Severity of dystonia improved from 31 to 10 points (median, 68% improvement, p<0.01) in the primary dystonia group, whereas in secondary dystonia these changes were statistically insignificant (improvement from 40 to 31.5 points, 21.2%, p>0.05). However, the health-related quality of life significantly improved in both groups (primary dystonia: 0.378 vs. 0.788 and secondary dystonia: 0.110 vs. 0.388, p<0.01). Significantly more patients in the primary dystonia group responded to DBS treatment than those in the secondary dystonia group (83.3% vs. 37.5%, p<0.01). Conclusion - Our results are in accordance with previously published international findings demonstrating that DBS is a highly effective and long-lasting treatment option for primary dystonia. DBS is considerably less efficient in secondary dystonia; however, it still has a high impact on the quality of life presumably due to its pain-relieving effect.]

Clinical Neuroscience



[Introduction - While it is several decades ago that electrophysiological studies in the early stages after an ischaemic stroke revealed spontaneous activity in the affected muscles, today few data are available on the peripheral changes in later stages after a cerebrovascular event. The aim of this study was to detect electrophysiological signs that could indicate changes at the motor unit level occurring within a longer post-stroke period. Patients and methods - Forty-four patients who had developed hemiparesis after an ischaemic stroke in the area of the middle cerebral artery were involved in the study. Motor and sensory nerve conduction studies and electromyography were carried out on each side on six nerves and in five muscles respectively. Values between the affected and unaffected side were compared by statistical methods. Results - In patients with hemiparesis present for less then nine months, low M wave amplitudes, fibrillation potentials and an increased number of complex motor unit potentials were found on the affected side; in patients with symptoms present for more then nine months the mean duration and size index of the motor unit potentials in the paretic abductor digiti minimi muscle were increased. These data suggest a process of neurogenic type. The signs of distal axonal damage observed in the early period after stroke have been replaced later by chronic neurogenic changes. These changes could be the consequence of spinal motor neuron damage and axonal transport disturbance due to the loss of supraspinal trophic inputs. Conclusion - The correlation between the extent of electrophysiological changes and of the central motor deficit of the patient indicates the importance of delaying this process by appropriate rehabilitation procedures.]

[Migraine is a common health problem affecting women more commonly. It has been associated with an increased risk for cardiovascular events. In this study, we investigated whether aortic elastic properties is altered in migraineurs with low cardiovascular risk compared with healthy controls, in order to elicit further evidence on tentative association between migraine and increased risk of cardiovascular disease. Methods - Forty-three migraine patients with low CVD risk were enrolled to the study. Thirty-three volunteers, with a similar age and sex distribution served as a control group. Following parameters of the aortic elasticity were calculated: aortic strain, aortic stiffness (β) index and aortic distensibility. Results - Aortic strain was not statistically different between the study and control group. However, aortic distensibility and β index were significantly impaired in patients with migraine compared to control subjects Discussion - The elastic properties of the aorta in migreineurs may be different from normal by using easily available echocardiographic methods. This information may be a clue for clarification of cardiovascular system involvement in migraine.]
