    Seroprevalence of <i>coxiella Burnetii</I> in Human and Animal Populations in Tiirkiye: Meta-Analysis
    (Kafkas Univ, veteriner Fakultesi dergisi, 2023) Kilbas, Imdat; Kahraman Kilbas, Elmas Pinar; Ciftci, Ihsan Hakki
    This study aims to reveal Coxiella burnetii by examining the studies reporting Q fever seroprevalence in humans and animals in the last 25 years in Turkiye. In this study, based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), various databases were searched between January 1997 and October. 2022. A literature review was carried out using data analyses performed using the IBM SPSS Version 25.0 statistical package program and Comprehensive Meta-Analysis (CMA) program. Overall prevalence of C. burnetii in humans was 22.78% (95% CI: 16.43%-29.12%), overall prevalence in animals was 13.49% (95% CI: 10.04-16.93%) was detected. The mean prevalence of C. burnetii in sheep was 19.1%+/- 10.88, 10.46 +/- 6.39% in cattle, 15.21 +/- 10.01% in studies including cattle and sheep together, 11.17 +/- 10.74 in cattle, sheep and goats, and 12.4%+/- 1.15% in sheep and goats. As a result of this study, it was determined that the prevalence of Q fever in humans in Turkiye is high in those dealing with animals, women who had a miscarriage, and infertile individuals. Although it is known that this disease is seen in Turkiye, there are not enough case reports in the literature. Detailed studies on Q fever in humans and animals need to be conducted. Further studies are needed to evaluate Q fever risk factors and prevalence data together within the scope of One Health approach.

    Molecular Epidemiology of Carbapenem-Resistant Acinetobacter Baumannii Isolates in Turkiye: Systematic Review
    (Kare Publ, 2023) Kilbas, Elmas Pinar Kahraman; Kilbas, Imdat; Ciftci, Ihsan Hakki; Kahraman Kilbas, Elmas Pinar
    The World Health Organization has designated carbapenem-resistant Acinetobacter baumannii (CRAB) as a "critical" pathogen on the global priority list of antibiotic-resistant bacteria. This study aims to discuss the molecular epidemiology of CRAB isolates in Turkiye in the last 12 years and the prevalence of gene regions associated with resistance or pathogenesis using a systematic review method. Our study consists of a literature search, determination of eligibility and exclusion criteria, qualitative analysis of studies, data extraction, and statistical analysis. All studies were analyzed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Guidelines. The incidence rates of blaOXA-23, blaOXA-23-like, blaOXA-24/40, blaOXA-24/40-like, blaOXA-51, blaOXA-51-like, blaOXA-58, and blaOXA-58-like genes in CRAB strains were 76.4%, 68.6%, 1.2%, 3.4%, 97.0%, 98.6%, 8.4%, and 17.1%, respectively. It was determined that the prevalence of the blaOXA-23 and blaOXA-58 gene regions showed a statistically significant change over the years. Due to the high prevalence of A. baumannii strains carrying the blaOXA-23 variant, it is necessary to follow its geographical distribution and transposon and plasmid movements. Based on available data, molecular surveillance of CRAB strains should be standardized. In addition, sterilization and disinfection processes applied within the scope of an effective struggle against CRAB strains that can remain live on surfaces for a long time should be reviewed frequently.

    Age-Specific Seroprevalence of Hepatitis a Virus in Turkey Between 2000 and 2023: Systematic Review and Meta-Analysis
    (Mdpi, 2024) Ciftci, Ihsan Hakki; Koroglu, Mehmet; Demiray, Tayfur; Terzi, Huseyin Agah; Kilbas, Elmas Pinar Kahraman; Kahraman Kilbas, Elmas Pinar
    <bold>Background</bold>: Hepatitis A virus (HAV) is a leading cause of acute viral hepatitis and is primarily transmitted by the fecal-oral route. The clinical presentation and progression of the disease varies according to the age of the patient. Turkey is classified as a moderately endemic country, and HAV infection continues to be an important public health problem worldwide. <bold>Methods</bold>: In this study, a systematic meta-analysis was conducted to evaluate age-specific HAV seroprevalence rates in Turkey between 2000 and 2023. A comprehensive literature review identified 57 articles that met the inclusion criteria. The studies were assessed for quality, and seroprevalence rates were evaluated across four different age groups. Statistical analyses were performed using Comprehensive Meta-Analysis (CMA) software (CMAVersion 3.0) and SPSS (SPSS Statistics 25.0). <bold>Results</bold>: HAV seroprevalence rates were found to be 73.18% in the 0 < 5 age group and 90.90% in the >35 age group. The overall seroprevalence estimated using a random effects model was 64.5% (95% CI: 58.3-70). High heterogeneity was observed among the studies, and the prevalence estimates changed when low-quality studies were excluded. <bold>Conclusions</bold>: This meta-analysis suggests that the increasing trend in HAV IgG seroprevalence in Turkey, especially among young populations, is likely due to the vaccination program initiated in 2012. Furthermore, the heterogeneity observed among regions highlights the importance of regional public health strategies. Future studies should focus on providing more detailed data to evaluate the long-term effects of vaccination and to explain regional differences in HAV seroprevalence.<br />

    The War Against the Resistance of <i>acinetobacter Baumannii</I>: a Meta-Analysis of Findings in Turkiye
    (Erciyes Univ Sch Medicine, 2022) Ciftci, Ihsan Hakki; Kilbas, Imdat; Kilbas, Elmas Pinar Kahraman
    Objective: Bacterial resistance to antibiotics continues to be a significant challenge to the global health system. This study was designed to examine changes in the antibiotic resistance of Acinetobacter baumannii (A. baumannii) strains isolated from various clinical samples taken between 2005 and 2020 and to support the development of new antibiotics policies for empirical treatment of multidrug-resistant isolates in Turkiye. Materials and Methods: This meta-analysis included a data search phase, determination of eligibility criteria, qualitative analysis of the studies selected, data extraction, and statistical analyses. All of the data were analyzed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Results: According to Clinical and Laboratory Standards Institute and/or European Committee on Antimicrobial Susceptibility Testing standards and a random effects model, the breakpoint estimate of A. baumannii strain resistance in Turkiye for ampicillin-sulbactam, ceftazidime, imipenem, meropenem, gentamicin, amikacin, ciprofloxacin, piperacillin-tazobactam, trimethoprim-sulfamethoxazole, netilmicin, colistin, and tigecycline was 90.7%, 92.1%, 86.8%, 87.3%, 72.6%, 63.7%, 88%, 91.2%, 76.7%, 27.1%, 7.9%, and 18.5%, respectively. Conclusion: The reported rates of A. baumannii resistance from different regions demonstrated heterogeneity. Unfortunately, the use of standard antibiotics is unlikely to provide effective therapy throughout Turkiye. New therapy options and protocols are needed.

    Molecular Characterization of Resistance and Virulence Genes in Enterococcus Faecium Strains Isolated Between 2000-2021; Systematic Review
    (Bilimsel Tip Yayinevi, 2022) Kahraman Kilbas, Elmas Pinar; Kilbas, Imdat; Ciftci, Ihsan Hakki; Kılbaş, Elmas Pınar Kahraman
    Introduction: The spread of Vancomycin-Resistant Enterococci (VRE) is a major threat in healthcare institutions, especially for patients in the risk group. The aim of this study is to reveal the antibiotic resistance genes, virulence genes and other accompanying factors detected in vancomycin resistant Enterococcus faecium strains isolated from various clinical specimens in different parts of Turkiye. Material and Methods: For this purpose, a systematic search was carried out using different electronic databases between January 2000 and September 2021. A total of 17 studies were evaluated within the scope of systematic review. Results: The vanA gene was detected the most between the years 2000-2007, and no statistically significant difference was found according to the years. The prevalence of the vanB gene was highest between 2008 and 2013, and no statistical difference was found according to the years (p> 0.05). The vanA gene was mostly detected in Eastern Anatolia, Black Sea, Mediterranean and Aegean, vanB Central Anatolia and Southeastern Anatolia regions. No reports related to the vanC gene were found. Since all strains were E. faecium in our study, it is an expected finding that the vanC gene region was never reported. The esp and hyl gene between 2014-2021. Conclusion: The prevalence of resistance and virulence genes among bacteria is a matter of great concern, limiting treatment options. In particular, effective measures should be taken to prevent healthcare-associated VRE infections, and each institution should report its own resistance data.
