[Survey of anxiolytic drug dependence in patients treated in psychiatric and addiction rehabilitation wards]. / A gyógyszerfüggoség elofordulásának vizsgálata pszichiátriai és addiktológiai rehabilitációs osztályokon kezelt betegek között.

Introduction: Anxiolytic drug dependence is a cause for growing concern worldwide including Hungary. Psychiatric patients and patients with other drug addictions are at increased risk for anxiolytic drug dependence. Yet, there is only limited scientific information about the real extent of this issue. Aim: To examine the frequency of use of benzodiazepine-containing drugs and comparing the consumption habits of patients treated in psychiatric and addiction rehabilitation wards in a hospital in Budapest. Method: The survey was based on an anonymously and voluntarily completed questionnaire during a face-to-face interview of 103 patients in two wards. The 19-item questionnaire targeted anxiolytic drug use and related behavioral patterns. Statistical analysis: Socio-demographic data were given with means and standard deviations or with percentages as appropriate. For the comparison between the two groups of patients, t-test, Mann­Whitney U-test or chi-square test were used in accordance with the distribution of the sample. Results: Symptoms indicating anxiolytic dependence, use of multiple anxiolytics, and combination of anxiolytic drugs with alcohol were very frequent in both wards. However, there were some significant differences between the two samples. Anxiolytic drug abuse and illicit drug use were significantly more frequent in patients at the addiction ward. Indicators of social status, particularly the place of residence, significantly influenced non-prescription misuse of anxiolytic drugs. Conclusions: The results draw attention to the high frequency of anxiolytic drug misuse and dependence in psychiatric and addiction patients warranting urgent action to confront this challenge.

Peroxidasin is secreted and incorporated into the extracellular matrix of myofibroblasts and fibrotic kidney.

Mammalian peroxidases are heme-containing enzymes that serve diverse biological roles, such as host defense and hormone biosynthesis. A mammalian homolog of Drosophila peroxidasin belongs to the peroxidase family; however, its function is currently unknown. In this study, we show that peroxidasin is present in the endoplasmic reticulum of human primary pulmonary and dermal fibroblasts, and the expression of this protein is increased during transforming growth factor-beta1-induced myofibroblast differentiation. Myofibroblasts secrete peroxidasin into the extracellular space where it becomes organized into a fibril-like network and colocalizes with fibronectin, thus helping to form the extracellular matrix. We also demonstrate that peroxidasin expression is increased in a murine model of kidney fibrosis and that peroxidasin localizes to the peritubular space in fibrotic kidneys. In addition, we show that this novel pathway of extracellular matrix formation is unlikely mediated by the peroxidase activity of the protein. Our data indicate that peroxidasin secretion represents a previously unknown pathway in extracellular matrix formation with a potentially important role in the physiological and pathological fibrogenic response.

Prevalence of selected enteropathogenic bacteria in Hungarian finishing pigs.

The aim of this study was to obtain prevalence estimates about the most important enteropathogenic bacteria: Lawsonia intracellularis, Brachyspira hyodysenteriae, Brachyspira pilosicoli, Salmonella enterica and Clostridium perfringens A and C in Hungarian farrow-to-finish pig herds. A total of 31 herds were selected, from where six pooled faecal samples, each containing three individual rectal faecal samples were collected from fattening pigs of 5-6 months of age. All 186 samples were examined by polymerase chain reaction (PCR) for the presence of the pathogens mentioned above. Lawsonia intracellularis was found in 29 herds (93.55%) and in 108 samples (58.06%); B. hyodysenteriae in 14 herds (45.16%) and in 23 samples (12.37%); B. pilosicoli in 19 herds (61.29%) and in 53 samples (28.49%); S. enterica in 17 herds (54.83%) and in 40 samples (21.50%). We detected the presence of C. perfringens A in 19 herds (61.29%) and in 46 samples (24.73%), while C. perfringens C was found in 8 herds (25.81%) and in 11 samples (5.91%). All examined herds were infected with one or more of these agents. Herds with diarrhoea in the mid- to late finishing phase had almost 10 times higher prevalence of B. hyodysenteriae than herds without such a history.
