Saliva in the Diagnosis of Covid-19
(Galenos Publ House, 2021) Kilbas, Elmas Pinar Kahraman; Altindis, Mustafa
The use of saliva samples for the diagnosis of severe acute respiratory syndrome-Coronavirus-2 (SARS-CoV-2) provides several advantages over the use of nasopharyngeal (NP) swabs, such as comfort, ease of self-collection, less use of personal protective equipment, and protection of healthcare personnel from transmission. This review included current studies using saliva samples for the detection of SARS-CoV-2, comparing its sensitivity, cycle threshold, and specificity with those of NP swab. In the literature, the sensitivity rates of saliva samples in the diagnosis of SARS-CoV-2 ranged from 70% to 98%. Despite different opinions, we concluded that saliva is a reliable sample for the detection of SARS-CoV-2. However, studies with large samples and comparing different diagnostic methods are needed to reach precise and reliable results and include saliva collection in diagnostic guidelines.

(2022) Kılbaş, Elmas Pınar Kahraman; Aslan, Ferhat Gürkan; Altindis, Mustafa
Şiddetli akut solunum sendromu koronavirüs 2 (SARS-CoV-2), koronavirüs hastalığı 2019'un (COVID-19) etkeni olarak tanımlandı ve genomik veriler ilk olarak 10 Ocak 2020'de Çin tarafından paylaşıldı. O tarihten itibaren, dünya genelinde toplanan örneklerden viral genomu dizilemek için çok büyük çaba harcandı. Yakın geçmişte, kökenleri izlemek ve bulaşıcı ajanların evrimini anlamak, salgınların yayılma zincirlerini araştırmak, hem etkili ve hızlı moleküler tanı testlerinin geliştirilmesini kolaylaştırmak hem de tedavi ve aşıların araştırılmasına katkıda bulunmak için, yeni nesil dizileme (NGS) stratejileri, başarıyla kullanılmıştır. Teknoloji ve bilimdeki son gelişmeler, COVID-19'un etkeni olan ağır akut solunum sendromu koronavirüsü-2'nin (SARS-CoV-2) genomlarının, bir vakanın tanımlanmasından sonraki saatler veya günler içinde dizilenmesine olanak sağlamıştır. Bu sayede, ilk kez, bir pandeminin halk sağlığı ve epidemi boyutu gerçek zamanlı olarak izlenebilmektedir. SARS-CoV-2 genom dizilerinin erken paylaşımı, moleküler tanı testlerinin hızla geliştirilmesine olanak sağlayarak, küresel hazırlığa ve karşı önlemlerin tasarımına katkıda bulunmuştur. Hızlı, büyük ölçekli virüs genom dizilimi, viral salgınların dinamiklerini anlama ve kontrol önlemlerinin etkinliğini değerlendirmede oldukça önemlidir. SARS-CoV-2 gen dizilimi, gelişmiş tanılar, karşı önlemlerin geliştirilmesi ve hastalık epidemiyolojisinin araştırılması dahil olmak üzere birçok farklı alanda kullanılabilir. COVID-19'un etiyolojik ajanının genomik dizisini tam olarak tanımlamak için etkili ve hızlı dizileme yöntemlerinin geliştirilmesi, tanısal moleküler testlerin tasarımı ve pandemi yayılımını azaltmada etkili önlemlerin alınması ve stratejilerin belirlenmesinde temel olmuştur. Mevcut dizilerin sayısından anlaşıldığı gibi, SARS-CoV-2 genomlarına, farklı yaklaşımlar ve dizileme yöntemleri uygulanabilir. Bununla birlikte, her teknoloji ve dizileme yaklaşımının kendi avantajları ve sınırlamaları vardır. Bu derlemede, SARS-CoV-2 genomlarının dizilenmesi için şu andaki mevcut platformlar ve metodolojik yaklaşımlardan bahsedilecektir.

The War Against the Resistance of acinetobacter Baumannii: 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.

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
Background: 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. Methods: 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). Results: 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. Conclusions: 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.

Prevalence of Colistin-Resistant Klebsiella Pneumoniae Isolates in Turkey Over a 20-Year Period: a Systematic Review and Meta-Analysis
(Multidisciplinary Digital Publishing Institute (MDPI), 2025) Kahraman Kilbas, E.P.; Kilbas, I.; Ciftci, I.H.
Klebsiella pneumoniae is one of the leading causes of healthcare-associated infections and poses challenges in its treatment owing to its high antibiotic resistance. The development of resistance to colistin, which is used as a last resort, has become a major public health problem worldwide. This study was planned according to the PRISMA guidelines and included studies reporting the prevalence of colistin-resistant K. pneumoniae in Turkey between 2004 and 2024 through a systematic literature review. A total of 28 original research articles were included in the meta-analysis. Data were analyzed using the SPSS and CMA software. The pooled colistin resistance of a total of 8916 K. pneumoniae strains from 28 studies included in this meta-analysis was found to be 1.63% (95% CI: 1.51–3.12). Colistin resistance increased significantly over time. A higher resistance rate was detected in the strains tested using the EUCAST guidelines and broth microdilution method. The year of the study and validation methods contributed to the heterogeneity observed in the studies. This meta-analysis reveals that colistin-resistant K. pneumoniae strains have increased over time in Turkey. Current data show that colistin resistance is not only a laboratory finding but has become a crisis, requiring urgent action in terms of hospital infection management and patient safety. Regional and global measures should be taken to ensure the appropriate use of antibiotics to control the development of resistance. © 2025 by the authors.

A Systematic Review and Meta-Analysis of Molecular Characteristics on Colistin Resistance of acinetobacter Baumannii
(Mdpi, 2024) Ciftci, Ihsan Hakki; Kilbas, Elmas Pinar Kahraman; Kilbas, Imdat
Background: This study aimed to determine the molecular epidemiology of colistin-resistant A. baumannii in the last ten years and the frequency of gene regions related to pathogenesis, to compare the methods used to detect genes, and to confirm colistin resistance. Methods: This meta-analysis study was conducted under Preferred Reporting Items for Systematic Reviews and Meta-Analysis Guidelines. In the meta-analysis, research articles published in English and Turkish in electronic databases between January 2012 and November 2023 were examined. International Business Machines (IBM) Statistical Package for the Social Sciences (SPSS) Statistics for Macbook (Version 25.0. Armonk, NY, USA) was used for statistical analysis. The Comprehensive Meta-Analysis (CMA) (Version 3.0. Biostat, NJ, USA) program was used for heterogeneity assessment in the articles included in the meta-analysis. Results: After evaluating the studies according to the elimination criteria, 18 original articles were included. Among colistin-resistant strains, blaOXA-51 positivity was 243 (19.61%), blaOXA-23 was 113 (9.12%), blaOXA-58 was 7 (0.56%), blaOXA-143 was 15 (1.21%), and blaOXA-72 was seen in two (0.16%) strains. The positivity rates of pmrA, pmrB, and pmrC were found to be 22 (1.77%), 26 (2.09%), and 6 (0.48%). The mcr-1 rate was found to be 91 (7.34%), the mcr-2 rate was 78 (6.29%), and the mcr-3 rate was 82 (6.61%). Conclusions: The colistin resistance rate in our study was found to be high. However, only some research articles report and/or investigate more than one resistance gene together. Additionally, it may be challenging to explain colistin resistance solely by expressing resistance genes without discussing accompanying components such as efflux pumps, virulence factors, etc.
Sakarya İlinde İçme ve Kullanma Sularından İzole Edilen Escherichia Coli Suşlarının Antibiyotik Direnç Durumlarının Belirlenmesi
(2024) Naşide,; Kılbaş, Elmas Pınar Kahraman; Çıftcı, Ihsan Hakkı
Su sistemlerinde patojen kontaminasyonu giderek artmakta ve bu durum, özellikle çocuklar arasında gastrointestinal enfeksiyonların artmasına yol açmaktadır. Bu çalışmanın amacı, Sakarya il sınırlarında içme ve kullanma sularındaki Escherichia coli kontaminasyon riskini belirlemek ve izole edilen suşların antibiyotik direnç durumlarını incelemektir. Sakarya ilçelerinden 2023-2024 yılları arasında toplanan 450 su numunesinden E. coli izolasyonu, membran filtreleme yöntemi ve kromojenik koliform agar (CCA) kullanılarak yapıldı. Bakterilerin antibiyotik dirençleri disk difüzyon yöntemi ile değerlendirildi. Çalışmada 450 su numunesinin %15,6'sında E. coli tespit edildi. Geyve ilçesinden alınan su numunelerinin %72'sinde E. coli bulunmuş olup, bu oran diğer ilçelere göre istatistiksel olarak anlamlı derecede yüksek bulundu (p<0.05). İzole edilen suşların %25,71'inin bir veya daha fazla antibiyotiğe dirençli olduğu belirledi. E. coli suşları genel olarak karbapenemler ve 3. kuşak sefalosporinlere duyarlıdır, ancak bazı bakteri izolatlarında penisilin ve sefalosporinlere karşı direnç tespit edildi. Tarım ve hayvancılığın yoğun olduğu bölgelerde içme ve kullanma sularında yüksek E. coli kontaminasyonu ve antibiyotik direnci tespit edilmiştir. Bu durum, yanlış ve aşırı antibiyotik kullanımının bir sonucu olarak görülmektedir. İçme sularındaki bu kontaminasyon, halk sağlığı açısından büyük bir risk oluşturmaktadır. İçme ve kullanma sularındaki E. coli varlığı, suyun dezenfeksiyonunda eksiklikler olduğunu ve fekal kontaminasyon riskini işaret etmektedir. Su arıtma tesislerinin ve dezenfeksiyon yöntemlerinin iyileştirilmesi, antibiyotik direncinin önlenmesi ve halkın bilinçlendirilmesi büyük önem taşımaktadır. Bu çalışmanın sonuçları, suyun güvenli ve hijyenik bir şekilde temin edilmesinin gerekliliğini vurgulamaktadır.
Acute Serious Hepatitis of Unknown Cause in Children
(Galenos Publishing House, 2022) Kılbaş, E.P.K.; Altındiş, M.
On April 5, 2022, an increase in cases of acute hepatitis of unknown etiology was reported in previously healthy children under the age of 10 in the United Kingdom. Since there is no link between these patients, called acute non-HepA-E hepatitis, and viral hepatitis agents (hepatitis A, B, C, D, and E), the possible etiology, and pathogenesis of this emergency is being investigated. One of the alarming features of this epidemic is the high requirement for liver transplantation in a fraction of the cases. In cases other than hepatitis A, B, C, D, and E, a case definition is made by looking at a series of clinical pictures, including serum transaminase levels and age. As of August 26, 2022, 513 cases of acute hepatitis have been reported in Europe and 1,010 globally. Adenovirus was detected in 75% of cases tested in the UK, but data for other countries are still lacking. The role of other etiologic agents is still under investigation. The exact disease pathogenesis has not yet clear. Evidence of human-to-human transmission of the disease remains unclear. Epidemiological studies are critical in clarifying the uncertainties regarding the existence of links between the cases reported to date. Continuing the national and international surveillance activities of the countries in an organized manner is the most basic issue required for the elimination of the epidemic.

(2024) Kaya, Tuğba; Terzi, Hüseyin Agah; Toptan, Hande; Kılbaş, Elmas Pınar Kahraman; Bayrakdar, Fatma; Cosgun, Yasemin; Altındiş, Mustafa
Objective: This study aimed to determine the seasonal distribution of the factor data of viral agents determined by the multiplex PCR method in routine practice in patients admitted to the hospital with upper respiratory tract infection symptoms and to detect oseltamivir resistance in viruses that are positive for Influenza A (H1N1). Methods: Nasopharyngeal swab and bronchoalveolar lavage samples of 354 patients between the ages of 0-94 who were admitted to the Sakarya University Sakarya Training and Research Hospital with symptoms of upper respiratory tract infection between 12 September 2019 and 19 February 2020 were studied with the multiplex PCR method. Oseltamivir resistance was investigated in 11 samples selected from Influenza A (H1N1) positive samples by Sanger sequence analysis method. Results: One or more respiratory viruses were identified in 233 (66%) of 354 respiratory samples evaluated. Of these, 64 (27.5%) are Influenza A/H1N1, 4 (1.7%) are Influenza A/H3N2, 24 (10.3%) are Influenza B, 64 (27.5) are Respiratory. Syncytial Virus A/B (RSV A/B), 58 (24.9%) Rhinovirus/Enterovirus, 18 (7.7%) Adenovirus, 12 (5.2%) Human Metapneumo Virus (hMPV) ), 10 (4.3%) Bocavirus, 4 (1.7%) Parainfluenza 1, 7 (3%) Parainfluenza 3, 3 (1.3%) Parainfluenza 4, 5 (2.1%) were found to be Coronavirus HKU1 and 13 (5.6%) were found to be Coronavirus NL63. More than one factor was detected simultaneously in 45 of 233 positive samples (19.3%). Oseltamivir resistance was not found in any of the 11 influenza A/H1N1 positive samples. Conclusion: No oseltamivir resistance was observed in any of the Influenza A/H1N1 positive samples evaluated in this study. Periodic analysis of influenza A/H1N1 strains for oseltamivir resistance is necessary to guide empirical treatment.
Investigation of the Synergic Effect of the Colistin/Sulbactam Combination in Carbapenem-Resistant acinetobacter Baumannii Complex Strains With Time-Kill and Checkerboard Methods
(Bilimsel Tip Yayinevi, 2021) Kilbas, Imdat; Hatipoglu, Huseyin; Kilic, Umit; Kahraman Kilbas, Elmas Pinar; Koroglu, Mehmet; Altindis, Mustafa
Introduction: Infections caused by carbapenem-resistant Acinetobacter strains have become very common in recent years, and the most frequently used medicinal treatment is colistin. Combination treatments should also be applied to prevent development of resistance to colistin. This study examines the in vitro synergic effect of the colistin/sulbactam combination in carbapenem-resistant Acinetobacter strains with the time-kill and checkerboard methods. Materials and Methods: Twenty carbapenem-resistant Acinetobacter baumannii-calcoaceticus complex strains, which were isolated from various clinical samples, were included in this study. Strains were identified with mass spectrometry, and antibiotic sensitivity results were determined with the VITEK 2 (R) system. The in vitro effect and synergic activity of the colistin, sulbactam, and colistin/sulbactam combination on the carbapenem-resistant strains were determined using the time-kill and checkerboard methods. Seventeen strains were examined with the time-kill method, and twenty strains were examined using the checkerboard method. The fractional inhibitory concentration index of strains was calculated for detection of synergic effect. Results: Using the time-kill method applied on the colistin/sulbactam combination showed that the combination had a synergic effect on all 17 strains, while sulbactam alone did not have a bactericidal effect in the studied concentrations. When applying the checkerboard method, it was determined that the colistin/sulbactam combination had a synergic effect on 17 of the strains (85%) and an additive effect on 3 strains (15%), sulbactam had a low effect alone (15%), and colistin was effective on all strains. Conclusion: Study results indicated that the colistin/sulbactam combination had a high level of synergic effect on all studied strains using both methods.
