[HAEMOGLOBIN CYCLICITY IN RENAL ANAEMIA]

REUSZ György, SZABÓ J. Attila

[Erythropoiesis stimulating agents are glycoproteins in which the oligosaccharide chains that terminate in sialic acid bind to the peptide with glycosidic bond. The lower the sialic acid content of the erythropoietin, the higher its receptor affinity, while its half-life in the circulation decreases. The biological effect depends on the balance of these factors. In the third-generation erythropoiesis stimulating molecule CERA (continuous erythropoietin receptor activator) a large polyethylene glycol molecule is substituted for sialic acid to ensure slow elimination and better biological efficiency. During treatment with erythropoiesis stimulating agents, haemoglobin levels show cyclic fluctuation. This cyclicity is undesirable, so its frequency and amplitude should be reduced as much as possible. The most recent results suggest that CERA may reduce haemoglobin cyclicity.]

[OUR EXPERIENCE WITH COMBINED ANTIVIRAL TREATMENT IN PATIENTS WITH CHRONIC HEPATITIS C WITH PERSISTENTLY NORMAL ALANINE AMINOTRANSFERASE LEVELS]

HORVÁTH Gábor, TOLVAJ Gyula, HALÁSZ Tünde, STOTZ Gyula

[INTRODUCTION - Persistently normal alanine aminotransferase levels, which occur in a fraction of patients chronically infected with hepatitis C virus, do not rule out the presence of chronic hepatitis C, even of that with advanced inflammation and fibrosis. Here we report our results of the treatment of these patients. PATIENTS AND METHODS - Patients with histologically confirmed chronic hepatitis C received combined antiviral treatment with pegylated interferon (alfa-2a 1×180 μg/week or alfa-2b 1×1.5 μg/kg/week) and ribavirin (800- 1200 mg/day) for 48-52 weeks. The alanineaminotransferase levels of 21 patients (14 females, 7 males, age: 20-54, mean 38 years) did not reach the upper limit of normal (40 U/l) during the period of observation (≥6 months). There were 19 and 2 cases with hepatitis C virus genotype 1b and 3, respectively. The patients' hepatitis activity index was 3.7 1.75, fibrosis score: 0.9 0.64, baseline viral titer: 1.18 1.12×106 IU/ml, alanine-aminotransferase level: 33.51 7.2 U/l. The last 100 unselected patients with elevated alanine-aminotransferase levels enrolled in treatment for chronic hepatitis C and who were followed for at least 6 months served as the control group with the following parameters: 41 females and 59 males (age: 18- 65, mean: 45.65 years), viral genotypes: 98 and 2 cases of type 1 and 3, respectively, hepatitis activity index: 5.44±4.03, stage: 1.29±1.00, baseline viral titer: 4.13±6.25×106 IU/ml. RESULTS - In the study group, all patients were hepatitis C virus RNA negative at the end of the treatment and with one exception remained so by the end of the 6-month follow-up period (20/21), while the sustained virologic response was 36% in the control group. The pretreatment normal alanine aminotransferase level decreased significantly (15.26 4.9 vs 33.51 7.2 U/l, p<0.001) by the end of the treatment, and remained at this level during the follow-up in all except one relapse case. CONCLUSION - The efficacy of the combined antiviral treatment is high in patients with persistently normal alanine aminotransferase levels, possibly due to the relatively younger age, the higher proportion of females, the lower baseline viral titer, and the less advanced liver disease (lower inflammatory activity and less or absent fibrosis) observed in this group. Combined antiviral treatment is recommended for patients with histologically confirmed chronic hepatitis C with normal alanine aminotransferase levels, even with mild inflammatory activity and minimal or absent fibrosis in the liver tissue. The previous suggestions based on published evidence to revise the upper limit of the normal range of alanine aminotransferase level are supported by the results of this study.]

[TREATMENT OF ANAEMIA IN A PATIENT WITH SMALL CELL LUNG CANCER]

TAMÁSI Lilla, WOLLÁK András

[INTRODUCTION - Anaemia is a common complication among patients with malignant tumours, and is due to the disease itself or to the oncologic treatment. Anaemia worsens the patient’s quality of life and hampers anti-cancer treatment in the appropriate intervals and doses. Erythropoiesis stimulating protein therapy in the anaemia of oncologic patients raises the haemoglobin level, reduces the need for red blood cell transfusion and improves quality of life. This drug has recently become accessible in Hungary for the treatment of chemotherapy-induced anaemia in patients with small cell lung cancer. CASE REPORT - In this paper the case of a 64- year-old woman with small cell lung cancer who survived for more than 2 years is presented. Two-line chemotherapy was administered together with irradiation and darbepoetin alpha supportation. The successful treatment of anaemia with darbepoetin alpha permitted the administration of chemotherapy in the necessary intervals and doses. CONCLUSIONS - The adequate use of erythropoiesis stimulating protein facilitates the management of patients with small cell lung cancer, and improves their quality of life.]

[Zonisamide: one of the first-line antiepileptic drugs in focal epilepsy ]

JANSZKY József, HORVÁTH Réka, KOMOLY Sámuel

[Chronic administration of antiepileptic drugs without history of unprovoked epileptic seizures are not recommended for epilepsy prophylaxis. Conversely, if the patient suffered the first unprovoked seizure, then the presence of epileptiform discharges on the EEG, focal neurological signs, and the presence of epileptogenic lesion on the MRI are risk factors for a second seizure (such as for the development of epilepsy). Without these risk factors, the chance of a second seizure is about 25-30%, while the presence of these risk factors (for example signs of previous stroke, neurotrauma, or encephalitis on the MRI) can predict >70% seizure recurrence. Thus the International League Against Epilepsy (ILAE) re-defined the term ’epilepsy’ which can be diagnosed even after the first seizure, if the risk of seizure recurrence is high. According to this definition, we can start antiepileptic drug therapy after a single unprovoked seizure. There are four antiepileptic drugs which has the highest evidence (level „A”) as first-line initial monotherapy for treating newly diagnosed epilepsy. These are: carbamazepine, phenytoin, levetiracetam, and zonisamide (ZNS). The present review focuses on the ZNS. Beacuse ZNS can be administrated once a day, it is an optimal drug for maintaining patient’s compliance and for those patients who have a high risk for developing a non-compliance (for example teenagers and young adults). Due to the low interaction potential, ZNS treatment is safe and effective in treating epilepsy of elderly people. ZNS is an ideal drug in epilepsy accompanied by obesity, because ZNS has a weight loss effect, especially in obese patients.]

TLR4 (Toll-like receptor-4) expression and frontal-cingulate volumes in schizophrenia

LI Hua, KÉRI Szabolcs

Evidence suggests that pathogen-associated pattern recognition receptors (Toll-like receptors, TLRs) are implicated in the pathophysiology of schizophrenia. TLRs are important in both peripheral immune responses and neuronal plasticity. However, the relationship between peripheral TLR expression and regional brain volumes is unknown in schizophrenia. We therefore assessed 30 drug-naïve, first-episode patients with schizophrenia. TLR4+/TLR1+ monocytes were measured using flow-cytometry. High resolution magnetic resonance images (T1 MRI) were obtained and analyzed with FreeSurfer. Results revealed significant negative correlations between the percentage of TLR4+ monocytes, mean fluorescent intensities, and brain volumes in frontal and anterior cingulate regions. The measures of TLR1+ monocytes did not show significant relationships with regional brain volumes. These results raise the possibility that abnormal TLR-activation is associated with decreased brain volumes in schizophrenia.

Effects of valproate, carbamazepine and levetiracetam on Tp-e interval, Tp-e/QT and Tp-e/QTc ratio

YASAR Altun, ERDOGAN Yasar

Aim - To evaluate P-wave dispersion before and after antiepileptic drug (AED) treatment as well as to investigate the risk of ventricular repolarization using the Tpeak-Tend (Tp-e) interval and Tp-e/QT ratio in patients with epileptic disorder. Methods - A total of 63 patients receiving AED therapy and 35 healthy adults were included. ECG recordings were obtained before and 3 months after anti-epileptic treatment among patients with epilepsy. For both groups, Tp-e and Tp-e/QT ratio were measured using a 12-lead ECG device. Results - Tp-e interval, Tpe/QT and Tp-e/QTc ratios were found to be higher in the patient group than in the control group (p<0.05, for all), while QTmax ratio was significantly lower in the patient group. After 3 months of AED therapy, significant increases in QT max, QTc max, QTcd, Tp-e, Tp-e/QT, and Tp-e/QTc were found among the patients (p<0.05). When the arrhythmic effects of the drugs before and after treatment were compared, especially in the valproic acid group, there were significant increases in Tp-e interval, Tp-e/QT and Tp-e/QTc values after three months of treatment (p<0.05). Carbamazepine and levetiracetam groups were not statistically significant in terms of pre- and post-treatment values. Conclusions - It was concluded that an arrhythmogenic environment may be associated with the disease, and patients who received AED monotherapy may need to be followed up more closely for arrhythmia.

Association of anterior thoracic meningocele and azygos lobe of the lung

DENIZ Ersay Fatih, SENAYLI Atilla, BICAKCI Ünal

Here we report an anterior thoracic meningocele case. Twoyears- old female patient was presented with kyphosis. Azygos lobe of the lung was also demonstrated during radiological studies. Posterolateral thoracotomy incision and extralpeural approach was performed for excision of the anterior meningocele to untether the cord. Although both anomalies are related to faulty embryogenesis and it is well known that faulty embryogenesis may also reveal coexisting abnormalities, we could not speculate a common mechanism for anterior thoracic meningocele and azygos lobe of the lung association.
