OBJECTIVES: The beta-lactamases with extended spectrum of activity (ESBL) are medically one of the most important group of enzymes. Another group of beta-lactamases representing of Enterobacteriaceae is group of the AmpC-type cephalosporinases. The presented study provides identification and determination of the spectrum of resistance against different and clinically used antimicrobial drugs in the clinical isolates of Escherichia coli. METHODS: These isolates had origin in different departments of the L. Pasteur University Hospital in Košice. The goal was the detection of beta-lactamase production with extended-spectrum effect and testing of AmpC-type cephalosporinases by several phenotypic tests in clinical isolates. MALDI-TOF MS analysis was performed on a Microflex MALDI Biotyper. Samples were positively tested for ESBL with the use of the disc diffusion method. PCR were performed with a series of primers designed for the detection of Ambler class A, B and C beta-lactamase genes. RESULTS: For all 485 isolates, we determined the production of ESBL, which we detected in 166 E. coli isolates, which represents a 34.2% prevalence of ESBL production. It is clear from the results that the prevalence of ESBL-producing E. coli out of the total number of E. coli investigated reached 34.2%. In the monitored period, we confirmed at least one resistance gene from 485 E. coli in 188 positive isolates. CONCLUSIONS: We describe a complex ESBL epidemiology. The study revealed a high rate of ESBL-producing E. coli isolates; blaTEM and blaSHV enzymes dominated in ESBL-positive E. coli isolates in the L. Pasteur University Hospital in Košice.

Yeasts frequently colonize non-sterile sites in the body. The aim of the study was to determine distribution in clinical samples and antifungal susceptibility to five antifungals. From January 2013 through June 2015, 800 isolates were obtained from intensive care unit patients. Candida albicans (58.9%), Candida glabrata (20.4%), Candida krusei (8.6%), and Candida parapsilosis (3.6%) were the leading species. Majority of the C. albicans isolates were susceptible to the fluconazole. Elevated voriconazole minimal inhibitory concentrations (MICs) were observed in isolates exhibiting high fluconazole MICs, most frequently in C. glabrata. Isolates with echinocandins MICs suggesting reduced susceptibility were only sporadic cases with the exception of Trichosporon spp. The amphotericin B MICs were slightly higher for some C. krusei.

Cytoletálne toxíny (cytolethal distending toxins; CDT) sú intracelulárne pôsobiace proteíny, ktoré zasahujú do bunkového cyklu eukaryotických buniek. Sú produkované gramnegatívnymi baktériami, ktoré majú afinitu k mukokutánnym povrchom a môžu sa uplatniť v patogenéze rôznych ochorení u cicavcov. Funkčný toxín sa skladá z troch proteínov: CdtB vstupuje do jadra a svojou nukleázovou aktivitou indukuje fragmentáciu jadra a rozrušenie chromatínu, CdtA a CdtC sú zodpovedné za pripojenie toxínu k povrchu hostiteľskej bunky. Cytotoxický účinok CDT vedie k zastaveniu bunkového cyklu predtým, ako bunka vstúpi do mitózy a k ďalším zmenám (rozšírenie bunky a smrť, apoptóza), ktoré závisia od typu bunky. CDT tak môže pôsobiť ako faktor virulencie u patogénnych baktérií, ktoré ho produkujú a prispievať k iniciácii niektorých ochorení. Zvlášť významné sú zápalové črevné ochorenia vyvolané črevnými baktériami, periodontitída, pri ktorej sa ako etiologický agens uplatňuje Aggregatibacter actinomycetemcomitans, a mäkký vred, ktorého pôvodcom je Haemophilus ducreyi.
Cytolethal distending toxins (CDT) are intracellularly acting proteins which interfere with the eukaryotic cell cycle. They are produced by Gram-negative bacteria with affinity to mucocutaneous surfaces and could play a role in the pathogenesis of various mammalian diseases. The functional toxin is composed of three proteins: CdtB entering the nucleus and by its nuclease activity inducing nuclear fragmentation and chromatin disintegration, CdtA, and CdtC, the two latter being responsible for toxin attachment to the surface of the target cell. Cytotoxic effect of CDT leads to the cell cycle arrest before the cell enters mitosis and to further changes (cell distension and death, apoptosis) depending on the cell type. Thus, CDT may function as a virulence factor in pathogenic bacteria that produce it and thus may contribute to the initiation of certain diseases. Most important are inflammatory bowel diseases caused by intestinal bacteria, periodontitis with Aggregatibacter actinomycetemcomitans as the aetiologic agent and ulcus molle where Haemophilus ducreyi is the causative agent.

BACKGROUND: Viral hepatitis B and C prevalence in the Roma population of eastern Slovakia is largely unknown. This study aimed to explore the prevalence and associated risk factors of chronic viral hepatitis B and C among Roma living in segregated communities in eastern Slovakia. METHODS: Data from the cross-sectional HepaMeta study conducted in Slovakia in 2011 among Roma living in rural communities were used. Participants were tested for the presence of HBsAg, anti-HBc IgG and anti-HCV. The risk factors were assessed mainly via a structured questionnaire/interview. RESULTS: Altogether 452 Roma were screened, and 11 were excluded due to missing data. A total of 441 patients were included (mean age 34.7 +/- 9.14 years; 35.2% men). 12.5% of participants were HBsAg positive, 40.4% anti-HBc IgG positive while negative for HBsAg and 47.2% of participants were negative for all serological markers of hepatitis B. Hepatitis C prevalence was very low (0.7%), while 2 out of 3 anti-HCV positive participants were coinfected with hepatitis B. Risk factors for hepatitis B infection were male sex, higher age, tattoo, and previous imprisonment. No difference was found in intravenous drug use, blood transfusions and sexual behaviour. CONCLUSION: More than half of the Roma residing in eastern Slovakia have been infected at one point in life with the hepatitis B virus, and 12.5% are HBsAg positive. Hepatitis C prevalence is very low, which is probably due to very low intravenous drug use.

BACKGROUND: Elevated gamma-glutamyl transpeptidase (GGT) is present approximately in half of all patients with non-alcoholic fatty liver disease (NAFLD). NAFLD is the liver manifestation of metabolic syndrome (MS). This study aimed to explore the relationship between GGT and MS or proinflammatory parameters. METHODS: Data from the cross-sectional HepaMeta study conducted in Slovakia in 2011 among Roma living in rural communities were used. Participants (n = 446) were divided into 2 groups; those with elevated GGT and those with normal GGT levels. MS was diagnosed according to the International Diabetes Federation criteria; presence of central obesity and low density lipoproteins (LDL) or high density lipoproteins (HDL), high triglycerides, hypertension, glucose intolerance or type 2 diabetes. Participants were tested for the presence of MS and its components, and biochemical tests for lipid levels (total cholesterol, HDL, LDL, TG) and inflammatory parameters (high sensitivity C-reactive protein--hs-CRP and ferritin) were performed. RESULTS: Of 446 Roma participants, only 29 (6.5%) had GGT levels above the normal value. After exclusion of patients with viral hepatitis and alcohol abuse, patients with elevated GGT suffered from MS more often (p < 0.001), and patients with more MS components had a higher risk of elevated GGT. We found a significant association between GGT and the individual MS components, except HDL (waist circumference > or = 94 cm in men or 80 cm in women: p < 0.01; BMI > 30: p < 0.001; fasting glucose > or = 5.6 mmol/l: p < 0.001; arterial hypertension: p < 0.05, and TAG > or = 1.7 mmol/l: p < 0.001). Patients with elevated GGT levels had also significantly higher hs-CRP (hs-CRP > 2 mg/l: p < 0.001; hs-CRP > 3 mg/l: p < 0.001) and ferritin (ferritin > 300 mg/l: p < 0.01) levels. CONCLUSION: Patients with MS have more significantly elevated levels of GGT. There is a significant association of GGT with individual MS components, except HDL and inflammatory parameters (hs-CRP, ferritin).

BACKGROUND: The simultaneous presence of chronic hepatitis B (CHB) and metabolic syndrome (MS) in the high-risk Roma community constitutes a high risk for liver cirrhosis and potentially hepatocellular carcinoma. This study aims to explore the relationship between MS and CHB. METHODS: Data from the cross-sectional HepaMeta Study conducted in Slovakia in 2011 among Roma living in rural communities were used. Participants were tested for the presence of MS, and lipid levels--total cholesterol, high density lipoproteins (HDL), low density lipoproteins (LDL), triglycerides (TG), apolipoprotein B100, and CHB HBsAg and anti-HBc IgG were also monitored. Viral load was measured in HBsAg-positive patients. RESULTS: A total of 452 patients were screened; MS was diagnosed in 29.6% of patients, and 12.5% had CHB. Anti-HBc IgG antibodies were present in 52.8% of patients. CHB patients had lower levels of total cholesterol (5.45 +/-1.21 vs. 4.71 +/- 1.23 mmol/l; p = 0.035), LDL cholesterol (median 2.2 mmol/l, interquartile range 0.88 mmol/l vs. 2.5 mmol/l, interquartile range 0.9 mmol/l; p = 0.01) and apolipoprotein B100 (median 0.66 mmol/l, interquartile range 0.26 mmol/l vs. 0.74 mmol/l, interquartile range 0.29 mmol/l; p = 0.025). Patients diagnosed with MS had a higher HBV DNA load than patients without MS (1,728.2 +/- 14.33 IU/ml vs. 12,779.1 +/- 20.9 IU/ml; p = 0.037). CHB patients with TC and apolipoprotein B100 within the reference range had a lower hepatitis B DNA (HBV DNA) load than patients with high or low values of TC or apolipoprotein B100. CONCLUSION: The prevalence of chronic hepatitis B and simultaneous presence of MS was high among Roma. HBsAg-positive patients had lower levels of total and LDL cholesterol along with decreased apolipoprotein B100. The viral load of chronic hepatitis B patients with MS was higher than in patients without MS.

BACKGROUND: Roma represent one of the largest and oldest minorities in Europe. Health of many of them, particularly those living in settlements, is heavily compromised by poor dwelling, low educational level, unemployment, and poverty rooted in generational poverty, segregation and discrimination. The cross-sectional population-based study using community based approach aimed to map the prevalence of viral hepatitis B/C and metabolic syndrome in the population living in separated and segregated Roma settlements and to compare it with the occurrence of the same health indicators in the majority population, considering selected risk and protective factors of these health indicators. METHODS: The sample consisted of 452 Roma (mean age = 34.7; 35.2% men) and 403 non-Roma (mean age = 33.5; 45.9% men) respondents. Data were collected in 2011 via questionnaire, anthropometric measures and analysed blood and urine samples. A methodology used in the study as well as in the following scientific papers is described in the Methods section (i.e. study design, procedures, samples, methods including questionnaire, anthropometric measurements, physical measurements, blood and urine measurements). CONCLUSIONS: There are regions of declining prosperity due to high unemployment, long-term problems with poverty and depleted resources. Populations living in these areas, i.e. in Central and Eastern Europe in Roma settlements, are at risk of poverty, social exclusion and other factors affecting health. Therefore, we should look for successful long-term strategies and tools (e.g. Roma mediators, terrain work) in order to improve the future prospects of these minorities.

BACKGROUND: The metabolic syndrome (MS) is a clustering of cardiovascular risk. The high prevalence of metabolic syndrome among populations of lower socioeconomic status is a cause of concern and calls for an effective public health response. OBJECTIVES: The aim of this study was to determine the prevalence of metabolic syndrome in the Roma population compared with the non-Roma population in the eastern part of Slovakia and to determine the parameter which has the strongest association with metabolic syndrome. RESULTS: 123 Roma and 79 non-Roma patients with metabolic syndrome were evaluated. In the subgroup of Roma men, we found that waist circumference conferred the highest chance of MS (more than 12-times), followed by triglycerides (TG) (3.670-times). In the subgroup of non-Roma men, we found that waist circumference conferred the highest chance of MS (more than 16-times), followed by high-density lipoprotein (HDL) (4.348-times increased risk per one unit decrease in HDL). In the subgroup of Roma women as well as non-Roma women, we found that serum TG conferred the highest chance of MS, followed by waist circumference for Roma women. Comparing non-classical risk factors for MS we found that only age (with OR 1.977) and high-sensitivity C-reactive protein (hsCRP) (OR 1.887) were significant and independent predictors of MS in Roma men. Among Roma women apolipoprotein B100 was also found to be an independent predictor of MS, besides age and hsCRP. CONCLUSION: Our study confirmed that the prevalence of metabolic syndrome is strongly associated with hypertriglyceridemic waist, besides other risk factors, a marker of the atherogenic metabolic triad among younger Roma population, which may be the reason for the increased cardiovascular (CV) morbidity and mortality in elderly Roma compared with non-Roma. In light of these results, better prevention of CV events for Roma minority settlements in Slovakia should be provided.

BACKGROUND: Obesity-induced metabolic syndrome is a multiple risk factor for cardiovascular (CV) risk factors and type 2 diabetes, and ethnic minorities seem to have unfavourable medical risk factors in general more frequently than majority populations. OBJECTIVE: The aim of this study was to evaluate the prevalence of cardiovascular risk factors in relation to metabolic syndrome in the Roma population compared with the non-Roma population residing in the eastern part of Slovakia. RESULTS: 123 Roma and 79 non-Roma patients with metabolic syndrome were evaluated. Men between 40-55 years of age had 4.76-times higher odds and women 5.26-times higher odds for metabolic sydrome compared with the younger population. We found statistically significant higher waist circumference in the Roma subpopulation and higher body mass index as well, although in selected population with metabolic syndrome. HDL cholesterol was significantly lower in both Roma men and women, and LDL cholesterol was not significant in men and women with metabolic syndrome. Triglycerides levels were significantly higher in non-Roma women only. High-sensitivity C-reactive protein (hsCRP) values were not in correlation with age but were associated with the increasing number of fulfilled criteria for metabolic syndrome in both subgroups (Roma, non-Roma), independently of gender. CONCLUSION: Our study confirmed higher prevalence of obesity, metabolic syndrome and other CV risk factors associated with metabolic syndrome among younger Roma population, which may be associated with increased cardiovascular disease (CVD) morbidity and mortality among elderly Roma compared with non-Roma.

BACKGROUND: The presence of hepatitis B infection (HBI) and metabolic syndrome (MS) at the same time constitutes a high risk for liver cirrhosis and potentially hepatocellular carcinoma. AIM: In this study we aim to explore the relationship between MS and HBI. METHODS: We used data from the cross-sectional HepaMeta study conducted in 2011 in Slovakia. Patients were tested for presence of MS, while lipid levels (total cholesterol, HDL, LDL, TG, apolipoprotein B100 and HBI (HBsAg and antiHBcIgG)) were also monitored. Viral load was measured in HBsAg positive patients. RESULTS: Altogether 855 patients were screened, MS was diagnosed in 25.1% of patients and 7.9% of patients presented with HBI. AntiHBcIgG antibodies were present in 34.6% patients. HBI patients had lower levels of total and LDL cholesterol along with a decreased apolipoprotein B100 (4.54 ± 0.84 vs. 5.0 ± 0.99 mmol/l, P=0.001; 2.29 ± 0.58 vs. 2.6 ± 0.68 mmol/l, P=0.001 and 0.71 ± 0.21 vs. 0.77 ± 0.23 mmol/l, P=0.013 respectively). Patients diagnosed with MS had higher HBV DNA load than patients without MS - 1300.2 (95% CI 506.06-3440.41) vs. 7661.3 (95% CI 2008.17-29,228.06) IU/ml; P=0.011. HBI patients with TC and apolipoprotein B100 in the reference range had lower HBV DNA load than patients with high or low values of TC or apolipoprotein B100. CONCLUSION: Hepatitis B patients had lower levels of total and LDL cholesterol along with a decreased apolipoprotein B100. Viral load of chronic hepatitis B patients with MS was higher than that in patients without MS.
