[INTRODUCTION - Adverse effects of treatment for chronic C virus hepatitis present an important problem both for the patient and the clinician. The reduction of drug doses or the suspension of therapy lessen the likelihood of recovery. PATIENTS, METHODS - Between 2001 and 2004, 66 patients with chronic hepatitis C received 180 μg pegylated interferon-alpha-2a per week and 800-1200 mg ribavirin per day, 6 of whom for 24 weeks and 60 patients for 48 weeks. During treatment, patients were closely followed in order to recognize any adverse effects early. RESULTS - Of the patients treated for 48 weeks, 48.3% developed adverse effects, with changes in the differential in 41.7%, and anaemia, low platelet count, neutropenia in similar rates. Further side effects included cardiac complications, skin symptoms, persisting high fever, autoimmune thyroiditis and liver failure, altogether in 9 cases. Dose reduction or temporary suspension of pegylated interferon-alpha-2a was necessary in 21 cases (31.7%), while complete cessation of this treatment was decided in 7 cases, most of them because of blood count changes. The 1000 to 1200 mg per day ribavirin had to be reduced in 30.8% of patients, while treatment was stopped in 3 cases. Long-term virological remission occurred in 48% of patients who received treatment for 48 weeks, whereas no such result was observed among any of those treated for 24 weeks. CONCLUSION - Adverse effects of variable severity developed in nearly half of the patients with chronic hepatitis C infection who received antiviral treatment for 48 weeks, but treatment had to be stopped in only a small proportion of this group. Early treatment of adverse effects can prevent the need to cease therapy and may improve its efficiency.]

[Disturbances in ventricular relaxation may lead to the development of diastolic heart failure. The analysis of left ventricular endomyocardial biopsy specimens may help understand the underlying structural and functional changes. Such analyses have lead to the recognition that at the optimal sarcomere length of the Frank- Starling mechanism (i.e., at 2.2 μm), passive force values of the cardiomyocytes are significantly higher in individuals with diastolic heart failure than in healthy controls. As a probable explanation to this finding, increased expression of the stiffer N2B isoform of the myofilamental titin protein, at the expense of the more elastic N2BA titin isoform, has been recognized. Moreover, decreased phosphorylation of the contractile proteins was also suggested to contribute to the development of diastolic heart failure. These changes together, and along with an increase in extracellular collagen content, may greatly contribute to the relaxation disturbance observed in diastolic heart failure.]

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.

[Wegener’s granulomatosis: diagnostic questions]

CSISZÉR Eszter, SOLTÉSZ Ibolya, FÜZESI Katalin

[INTRODUCTION - Wegener’s granulomatosis is a disease of unknown origin classified as an immune vasculitis. The main pathologic feature is necrotising granulomatous small vessel vasculitis. Clinically the upper and/or lower airways are affected most often as well as the kidneys in the generalised form. The highly specific antineutrophil cytoplasmic antibodies have diagnostic significance beside the pathology and clinical symptoms. PATIENTS AND METHODS - We have studied the clinical and diagnostic characteristics of 15 cases diagnosed in our centre from the last 25 years. All patients had pulmonary manifestation. We analysed the organ involvement, clinical signs indicating the diagnosis, chest radiography, chances for biopsies of diagnostic significance and the difficulties of differential diagnostics. RESULTS - The diagnosis was made based on histological samples from the upper airways in three cases and from the lower airways in six cases (in four cases the bronchoscopic biopsies were diagnostic, in two patients thoracotomy was necessary). In six cases, clinical signs and typical organ manifestations were the basis of the diagnosis. CONCLUSION - This very rarely occurring disease which is difficult to recognise requires pulmonological examination due to the involvement of lungs. If this diagnosis comes to mind - based on findings of bilateral, multiplex, round pulmonal shadows with cavitation - the pulmonologist should search for other organ manifestations and involve respective specialists. Ideally, diagnosis is established by histopathology or by positive cytoplasmic antineutrophil cytoplasmic antibodies.]

[Frontotemporal dementia - Part II Differential diagnosis, genetics, molecular pathomechanism and pathology]

GALARIOTIS Vasilis, BÓDI Nikoletta, JANKA Zoltán, KÁLMÁN János

[This is a comprehensive paper in three parts covering history, prevalence, clinical forms, differential diagnosis, genetics, molecular pathomechanism, pathology, clinical diagnosis and treatment of frontotemporal dementia (FTD). The second part focuses on the differential diagnosis, genetics, molecular pathomechanism and pathology. The clinical diagnosis of frontotemporal dementia is based on the presence of a prominent disturbance of the executive function and of frontal lobe syndrome or a progressive aphasic syndrome without severe global cognitive impairment. Of other dementias, it is primarily Alzheimer’s disease that it should be differentiated from, but other psychiatric disorders must also be ruled out. The disease has familial and sporadic forms. Recent identification of mutations in the gene encoding the microtubule-associated tau protein in the inherited frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17) has demonstrated that various tau dysfunctions can lead to neurodegeneration. Tau gene mutations have varied effects on the biology and function of the protein. This heterogeneous pathomechanism explains the wide range of clinical and neuropathological features observed in the FTDP-17. Tau and ubiquitin antibodies can be detected by sensitive immunohistochemical methods. The diagnosis of FTD should be based on neuropathological examination, and this is also the only method by which it can be definitely differentiated from other types of dementias.]

[Background and purpose - To investigate the association between the rs11136000 single nucleotide polymorphism (SNP) of the clusterin (CLU) gene, the rs541458 and rs3851179 SNPs of the phosphatidylinositol-binding clathrin assembly protein (PICALM) gene and Alzheimer’s disease (AD) in a Turkish population, and to determine whether there are any relationships between the CLU and the PICALM genotypes and behavioral and psychological symptoms of dementia (BPSD) in the Turkish population. Methods - One-hundred and twelve AD patients and 106 controls were included in this study. BPSD were evaluated by the Behavioral Pathology in Alzheimer’s Disease Rating Scale (BEHAVE-AD). SNPs in the CLU and the PICALM gene were genotyped by Real-Time PCR. Genotype distributions were assessed for the groups of patients and controls, for the patient groups with and without each BPSD, and “No BPSD” and “BPSD”. Results - The CLU and the PICALM genotypes were similar in the AD and control subjects, and the groups with and without each BPSD. There were also no significant differences between the “No BPSD” and the “BPSD” groups for the PICALM genotypes, but even without a statistical significance, it is notable that none of the “No BPSD” patients had genotype pattern CLU-rs11136000-TT, and the female subjects with genotype pattern CLU-rs11136000-TT had higher mean score of BEHAVE-AD. Conclusion - This study claims that investigated SNPs are not genetic risk factors for AD in a Turkish population. In addition, the rs541458 and rs3851179 of PICALM SNPs are not related to development of BPSD, but the rs11136000 of CLU SNP might be related to development of BPSD in AD female Turkish subpopulation.]

[Occurence and molecular pathology of low grade gliomas]


[Background - The WHO grade I. and II. low-grade gliomas represent nearly the 15% of all primary brain tumors. These tumours contain clinically, hisologically and molecularly distinct tumor types. According to their histologic characteristic, grade II glial tumours are the diffuse astrocytoma, oligodendroglioma and oligoastrocytoma subgroups; the ependymal tumors are not included in this study. Methods - In our publication, we analysed the histological diagnosed glioma cases between 2007 and 2011 at our institution. Results - Low-grade gliomas were diagnosed in 127 cases (62 male / 65 female), and the mean ages were 39 years (±20.3). More than half of the cancers were localizated in the frontal lobe, and the second most frequent area was the temporal lobe. Finally, we comlete our report with an overview of major molecular pathways in low-grade gliomas.]
