Letter Medical Education During the Covid-19 Pandemic: Experience From a Newly Established Medical School(Springer india, 2020) Tulek, Necla; Gonullu, Ugur; Basic Sciences[No Abstract Available]Review Hepatit B İnfeksiyonlarının İmmünopatogenezi(Bilimsel Tip Yayinevi, 2019) Tülek, Necla; Basic SciencesHepatit B infeksiyonları tüm dünyada majör sağlık problemleri arasında olup, siroz ve hepatoselüler karsinomanın en önemli nedenidir.Tedavide gelişmelere rağmen henüz kronik hepatit B infeksiyonunda kür sağlanamamaktadır. Hepatit B infeksiyonlarında klinik sonuçinfeksiyonun alınma yaşı, viral yük ve konağın immün yanıtına bağlıdır. Akut hepatitlerde klinik seyir subklinik hastalıktan, anikterikhepatite, ikterik hepatite ve fulminant hepatite kadar değişebilirken, kronik hepatitlerde hastalığın seyri asemptomatik inaktif durumdankronik hepatite, siroz ve hepatoselüler karsinomaya kadar değişebilir. Hepatit B virüsü hepatositlerde sitopatik olmayarak çoğalır veklinik sendromların çoğu immün yanıt ile ilişkilidir. İmmün sistem aktivasyonu virüsün eliminasyonunu sağladığı gibi karaciğer hasarınada neden olur. Hepatit B patogenezinde hücresel immün yanıt özellikle de CD8+ T hücreler santral olmasına rağmen immün sistemindiğer komponentleri de katkıda bulunur. Kronik hepatitli hastalarda hem doğal hem de adaptif immün yanıt zayıflamış ve T hücreyanıtı tükenmiş durumdadır. İmmünopatolojideki mekanizmaların daha iyi anlaşılması, yeni etkin tedavi stratejilerinin geliştirilmesindeyararlı olacaktır.Editorial Photo Quiz; Anthrax or Orf?(Doc design informatics Co Ltd, 2019) Tulek, Necla; Kilic, Esra Kaya; Ertem, GunayTuncer; Yuksekkaya, Esra; Basic Sciences[No Abstract Available]Article The Impact of Covid-19 Pandemic on Surveillance of Influenza and Influenza-Like Viruses: a Single Center Experience(2023) Özsoy, Metin; Tülek, Necla; Basic SciencesAims: Influenza and the agents responsible for influenza-like illness (ILI) are a significant cause of upper and lower respiratory tract infections, with a notable pattern of seasonal incidence. The surveillance of influenza and agents causing ILI is important for the developmentof a prophylaxis approach and infection control. In the present study, we utilize the Reverse transcription-polymerase chain reaction (RT-PCR) method to identify the presence of influenza virus and other agents associated with ILI in nasopharyngeal smears obtained from patients exhibiting symptoms of influenza and ILI. The study sample included patients who were admitted to multiple clinics and intensive care units (ICU) of the Health Sciences University Ankara Training and Research Hospital in the period preceding, and in the initial months and first year following the coronavirus disease 2019 (COVID-19) outbreak. Throughthe comparisons made in the study, the intention is to gain a better understanding of the influence of the COVID-19 pandemic on other viral infectious agents transmitted via the respiratory tract. Methods: Included in the study were 257 admitted to different wards and ICUs of our hospital due to symptoms of upper or lower respiratory tract infection and ILI between 2015 and 2021 (excluding data from 2017–2018). The study was conducted prospectively within the scope of the Global Influenza Hospital Surveillance Network project. Using sterile swabs, nasopharyngeal swab samples were collected from inpatients who provided informed consent for their participation in the study, and the samples were placed in a viral transport medium. The presence of influenza viruses (Influenza A, subtypes of Influenza A and Influenza B) and agents causing ILI (i.e. respiratory syncytial virus, coronavirus) was investigated with an RT-PCR approach. Results: The most common symptoms among the 257 patients included in the study with pre-diagnoses of influenza and ILI were cough (82.2%), fever (67.7%), shortness of breath (66.1%) and myalgia (40%). The RT-PCR detected a viral agent in 60 (23.3%) of the 257 patients, whereas no agent could be detected in 197 (76.6%) patients. Furthermore, 51 (18.5%) tested positive for influenza virus, five (1.9%) for respiratory syncytial virus (RSV), and four (1.5%) for SARS-CoV-2. An analysis of the results within two distinct time frames, namely prior to the COVID-19 pandemic (2016–2017, 2019–prior to December 10, 2020) and during the COVID-19 pandemic (between December 11, 2020 and 2021), influenza viruses (influenza A H1N1 and influenza A H3N2), RSV and influenza type B were identified as the dominant viruses before the COVID-19 pandemic, while the predominant viruses were a single influenza strain and four SARS-CoV-2 variants during the COVID-19 pandemic.A significant difference was noted in the distribution of viruses between the two time frames – prior to the pandemic and during the pandemic. Of the patients, 199 (77.4%) were discharged with full recovery while 58 patients died (22.6%). Of the 58 patients that died, 25 were female (25/131 females) and 33 were male (33/126 males), 11 had tested positive for influenza virus andone for RSV, while no infectious agent could be identified in 46 patients. Conclusion: The implementation of molecular testing methods for the identification of viral infectious agents among inpatients during influenza and ILI outbreaks, administering antiviral and prophylactic treatments targeting influenza, RSV and SARS-CoV-2 infections, and adopting infection control measures, could significantly decrease mortality and morbidity rates while mitigating the complications associated with these infectious agents.Article Citation - WoS: 1Retrospective Evaluation of Potential Rabies Exposure Cases Over Nine Years: Single-Center Experience(Bilimsel Tip Yayinevi, 2024) Demircan, Serife Altun; Kilic, Esra Kaya; Tulek, Necla; Kinikli, Sami; Bulut, Cemal; Basic SciencesIntroduction: T & uuml;rkiye is the only European country where suspected rabies exposure from animal contact is a significant public health concern. In this study, we evaluate cases investigated in our vaccination center, where individuals with suspected rabies exposure have been seeking consultation for many years. The evaluation encompasses demographic characteristics, distribution by years and seasons, the type of animal involved in the contact, the prevalence of stray animals, and the rabies vaccination status of owned animals. Materials and Methods: The study involves cases reported to the Public Health Center from those who sought consultation at our center between January 1, 2011, and December 31, 2019. Demographic characteristics, distribution by years and seasons, the type of animal involved in the contact, the prevalence of stray animals, and the rabies vaccination status of owned animals were retrospectively evaluated. Results: Over the nine years, there were a total of 39.731 cases, resulting in an average of 4414 cases per year. Of these cases, 61% were male, and 68.83% were between the ages of 15 and 64. The most cases occurred in summer and autumn. Of the suspected rabies contacts, 69% involved dogs, and 83.4% of these dogs were unowned. Forty-one point eight percent of the owned dogs were vaccinated. Eighty-nine point six percent of the cats were unowned, and the rate of vaccination among the owned cats was 28.2%. Over the years, there has been a decrease in the use of the 10 -day observation approach, while an increase in the administration of rabies vaccine and/or immunoglobulin has been observed. Conclusion: Seventy percent of all risky rabies contacts involve dogs, with a high rate of 84% of these dogs being unowned. To mitigate contact involving the risk of rabies, addressing the uncontrolled reproduction of stray animals, particularly dogs, and ensuring control and vaccination of the existing animal population appear to be primary measures. Improving the vaccination rate of owned animals, currently at only 30-40%, can prevent people from encountering risky rabies contacts, thereby potentially reducing the need for rabies prophylaxis significantly.Review Citation - WoS: 2Citation - Scopus: 3Akciğer Kanserinde İmmünoterapi ve Tedavide Multidisipliner Yaklaşım(Turkish Assoc Tuberculosis & Thorax, 2020) Karadurmuş, Nuri; Kaya, Akın; Göksel, Tuncay; Yılmaz, Ülkü; Tülek, Necla; Basic SciencesAkciğer kanseri dünya genelinde kanserle ilişkili ölümlerin başlıca nedeniolmaya devam etmektedir. Son 20 yılda kanser biyolojisi ve patogenezi hakkındaki bilgiler artmış, immün kontrol noktası inhibitörleri (İKNİ) kullanımasunulmuş ve böylece solid kanserlerin tedavisinde önemli bir dönem başlamıştır. Bu derlemede; tedavide yenilikler, immünoterapi ve tedavide multidisipliner yaklaşım çerçevesinde akciğer kanseri ele alınmıştır. Küçük hücreli dışıakciğer kanseri (KHDAK) en sık görülen ve özellikleri nedeniyle İKNİ tedavisinden ideal olarak yararlanabilecek akciğer kanseri türü olması nedeniyleyazının odak noktasını oluşturmuştur. Bu derleme, akciğer kanseri tedavisindeimmünoterapi yaklaşımının göğüs hastalıkları başta olmak üzere tüm branşlarda multidisipliner farkındalığını artırmayı ve yönetimi hakkında bilgi sağlamayıamaçlayan ilk Türkçe derlemedir. Ayrıca bu derleme, KHDAK tedavisinde İKNİkullanımına ilişkin son klinik çalışmaların dikkat çekici sonuçlarını sunmasıaçısından önem teşkil etmektedir. İmmünoterapi kanser tedavisinde yeni bir dönem başlatmıştır ve İKNİ tedavisinin kendine özgü etki mekanizması yeni bazı advers olay grubunun ortaya çıkmasına nedenolmuştur, bunlar arasında pnömonitis özellikle önemlidir ve advers olaylar konusunda gerektiğinde hastaların ilgili uzmanlık dalları ilekonsülte edilmesi gerekmektedir. Akciğer kanserinde tedavi, hastanın özellikleri, histolojik özellikler, genetik durum göz önünde bulundurularak her bir hastaya özel planlanmalı ve akciğer kanserli bir hastanın tanısal değerlendirilmesi ve en uygun şekilde tedavisi içingöğüs hastalıkları, göğüs cerrahisi, tıbbi onkoloji, radyasyon onkolojisi, patoloji ve radyoloji uzmanlık dalları arasında işbirliği sağlanmalıdır. Bununla birlikte, aile hekimleri de akciğer kanserinin erken tanınmasında ve ayrıca hastalarını tütün bırakmayı teşvik ederekkanserin önlenmesinde önemli rol oynayabilirler. Ayrıca, toplumda farkındalık yaratmak ve erken tanı için akciğer kanseri yönündentarama çalışmaları yapmak hedeflenmelidirArticle Tedavi Alan Kronik Hepatit B Hastalarında Serum Kantitatif Hbsag Düzeyi ile Viral Yük Arasındaki İlişkinin Araştırılması(Pamukkale University, 2020) Demirelli, Meryem; Tülek, Necla; Temoçin, Fatih; Yücel, Doğan; Erdinç, Fatma Şebnem; Ertem, Günay; Basic SciencesAmaç: Yakın geçmişe kadar HBsAg sadece hepatit B enfeksiyonun tanısında kullanılırken, günümüzde serum HBsAg kantitasyonu (qHBsAg)’nun, hepatit B virüsü (HBV) enfeksiyonunun viral monitörizasyonunda kullanılabileceğine dair veriler artmaya başlamıştır. Bu çalışmada inaktif hepatit B taşıyıcıları ile kronik aktif hepatit B hastaları arasındaki qHBsAg ile HBV DNA düzeyleri karşılaştırılmış ve tedavi başlanmış hastalarda tedavi süresince qHBsAg ile HBVDNA seyri izlenerek aralarındaki ilişki değerlendirilmiştir. Gereç ve yöntem: Çalışma Ankara Eğitim ve Araştırma Hastanesi Enfeksiyon Hastalıkları ve Klinik Mikrobiyoloji Kliniği’nde yapılmıştır. Kronik hepatit B (KHB) tanısıyla tedavi alan 71 hasta ve inaktif HBsAg taşıyıcısı 74 hasta çalışmaya dahil edildi. Bu hastalarda serum qHBsAg düzeyleri Elecsys HBsAg II cihazı ile çalışıldı. Bulgular: Nükleoz(t)id analoğu ile tedavi edilen hastalarda 6. ve 12. aydaki serum qHBsAg düzeyi ile HBVDNA arasında pozitif yönde bir korelasyon görüldü ve her iki parametrenin altı ay ve bir yıllık izlemindeki düşüş istatiksel olarak anlamlı bulundu (qHBsAg 6ay p=0,03, qHBsAg 12 ay p=0,001, HBV DNA 6 ay p=0,001, HBV DNA 12 ay p=0,001). Peg-IFN tedavisi alan kronik hepatit B hastalarında ise serum qHBsAg düzeyi ile HBVDNA arasında tedavi başlangıcı ve 6. ayında anlamlı bir ilişki olmayıp tedavi sonunda pozitif yönde korelasyon görüldü. PEG-IFN tedavisi alan hasta grubunda ise qHBsAg seviyeleri ile HBV DNA arasındaki korelasyon tedavi sonunda anlamlı (p=0,01) olarak saptandı.Article Citation - WoS: 2Citation - Scopus: 1Management of Chronic Hepatitis B in Special Patient Groups: a Consensus Report of the Study Group for Viral Hepatitis of the Turkish Society of Clinical Microbiology and Infectious Diseases-2023(Doc design informatics Co Ltd, 2023) Tekin, Sueda; Karakecili, Faruk; Binay, Umut Devrim; Celik, Ilhami; Tulek, Necla; Tutuncue, Ediz; Demirturk, Nese; Basic SciencesTurkish Society of Clinical Microbiology and Infectious Diseases Viral Hepatitis Working Group updated the consensus report on the management of chronic hepatitis B (CHB) in private hosts and special situations.

We aimed to assess whether vaccine status was associated with the severity of Omicron SARS-CoV-2 infection in hospitalized patients.Methods: We conducted an international, multi-centric, retrospective study in 14 centres (Bulgaria, Croatia, France, and Turkey). We collected data on patients hospitalized for >= 24 hours between 1 December 2021 and 3 March 2022 with PCR-confirmed infection at a time of exclusive Omicron circu-lation and hospitalization related or not related to the infection. Patients who had received prophylaxis by monoclonal antibodies were excluded. Patients were considered fully vaccinated if they had received at least two injections of either mRNA and/or ChAdOx1-S or one injection of Ad26.CoV2-S vaccines. Results: Among 1215 patients (median age, 73.0 years; interquartile range, 57.0-84.0; 51.3% men), 746 (61.4%) were fully vaccinated. In multivariate analysis, being vaccinated was associated with lower 28 -day mortality (Odds Ratio [95% Confidence Interval] (OR [95CI]) = 0.50 [0.32-0.77]), intensive care unit admission (OR [95CI] = 0.40 [0.26-0.62]), and oxygen requirement (OR [95CI] = 0.34 [0.25-0.46]), independent of age and comorbidities. When co-analysing these patients with Omicron infection with 948 patients with Delta infection from a study we recently conducted, Omicron infection was associated with lower 28-day mortality (OR [95CI] = 0.53 [0.37-0.76]), intensive care unit admission (OR [95CI] = 0.19 [0.12-0.28]), and oxygen requirements (OR [95CI] = 0.50 [0.38-0.67]), independent of age, comorbidities, and vaccination status.Discussion: Originally designed vaccines have remained effective on the severity of Omicron SARS-CoV-2 infection. Omicron is associated with a lower risk of severe forms, independent of vaccination and pa-tient characteristics. Guillaume Beraud, Clin Microbiol Infect 2023;29:642 (c) 2022 The Author(s).
