The Antibiotic Resistance Patterns of Klebsiella pneumoniae Clinic Isolates: A Comprehensive Meta-Analysis

Background/Purpose: Recently, Klebsiella pneumoniae has become a health care concern due to its production of extended-spectrum beta-lactamase (ESBL) and its resistance to carbapenem. In Turkey, systematic meta-analyses investigating antibiotic resistance in K. pneumoniae are lacking.Methods: Consequently, we performed a systematic review of the literature followed by a metaanalysis to investigate antibiotic resistance in K. pneumoniae. This study was designed and conducted in accordance with the PRISMA guidelines. We identified observational studies published from 2000 to 2015 using the various search engines. In total, 2,225 articles were published during this study period, but we only included 25 in our meta-analysis because of eligibility criteria.Results: We observed a significant increase in antibiotic resistance (&gt;40%) to the following antibiotics: cefazolin, amoxicillin-clavulanic acid, cefuroxime, cefepime, ceftriaxone, and ceftazidime. Unfortunately, the majority of these antibiotics were commonly prescribed for the treatment of K. pneumoniae infections. The rate of bacterial ESBL production has been steadily increasing and in this study was calculated at 39.66% ± 12.46%. In this study, we observed &gt;30% resistance to ciprofloxacin. Furthermore, the rates of resistance to imipenem and meropenem were 5.1% and 3.4%, respectively.Conclusion: The data obtained from this study may be beneficial for prescribing appropriate antibiotics and preventing their unnecessary use. The frequent checks of resistance rates with new detailed report may suggest to the development of National Antibiotic Stewardship.</p

Türkiye’de nonvalvüler atriyum fibrilasyonlu hastalarda vitamin K antagonisti ve yeni oral antikoagülan kullanımı uygulamalarını değerlendirmek için epidemiyolojik çalışma - AFTER*-2 çalışması dizaynı

Amaç: Atriyum fibrilasyonu (AF) önlenebilir iskemik inmenin en sık nedenlerinden biri olup artmış kardiyovasküler morbidite ve mortaliteyle ilişkilidir. Ülkemizde yeni oral antikoagülan kullanım sıklığı, vitamin K antagonisti kullanan hastalarda Uluslararası Düzeltme Oranı’nın (INR) etkin düzeyde kalma oranı ve AF tedavi yönetimi ile ilgili büyük bir çalışma mevcut değildir. Bu çok merkezli çalışmada amacımız nonvalvüler AF hastalarında epidemiyolojik verilerin analizi, takibi ve değerlendirilmesidir. Çalışma planı: Kırk iki merkezden elektrokardiyografisinde en az bir defa AF atağı tespit edilmiş ardışık 4100 erişkin hasta çalışmaya alınacaktır. Romatizmal mitral darlığı ve protez kapak hastalığı olan AF hastaları çalışmaya alınmayacaktır. Hastalar birinci yılın sonunda majör kardiyak sonlanım noktaları (ölüm, geçici iskemik atak, inme, sistemik tromboembolizm, majör kanama ve hastane yatışı) açısından değerlendirilecektir. Bulgular: İlk sonuçlar Haziran 2015 yılında bekleniyor. Majör kardiyak sonlanım noktaları açısından veriler Ocak 2016’da elde edilecektir. Sonuç: AFTER-2 çalışması ile ülkemizdeki non-valvüler AF hastalarının oral antikoagülan tedavi kullanım sıklığı ve çeşidi, varfarin alan hastalarda etkin INR düzeylerinde kalma oranı ve benimsenen tedavi yönetimi belirlenecektir. Ayrıca, ülkemizde AF’li hastalarda majör istenmeyen olay sıklığı ve bu olayların bağımsız belirteçleri de ortaya çıkarılacaktır (AFTER-2 Study ClinicalTrials.gov number, NCT02354456). Anahtar Kelimeler: Antikoagülan ilaç; atriyum fibrilasyonu/epidemiyoloji; ilaç kullanımı; elektrokardiyografi; uluslararası düzeltme oranı; varfarin.Objectives: Atrial fibrillation (AF) is one of the most common causes opreventable ischemic stroke and is related to increased cardiovasculamorbidity and mortality. There is a lack of data in Turkey on the use onew oral anticoagulants (NOACs), and time in therapeutic INR range (TTR) in vitamin K antagonist users and AF management modalityIn this multi-center trial, we aimed to analyze, follow and evaluate the epidemiological data in non-valvular AF patients. Study design: Four thousand one hundred consecutive adulpatients from 42 centers with at least one AF attack identified on electrocardiography will be included in the study. Patients with rheumatic mitral valve stenosis and prosthetic valve disease will be excluded from the study. At the end of one year, the patients will be evaluated in terms of major cardiac end points (death, transient ischemic attack, strokesystemic thromboembolism, major bleeding and hospitalization). Results: First results are expected in June 2015. Data about majocardiovascular end-points will be available in January 2016. Conclusion: The rates and kind of oral anticoagulant use, TTR in vitamin K antagonist users and main management modality applied in non-valvular AF patients will be determined by AFTER-2 studyIn addition, the rate of major adverse events (MACEs) and the independent predictors of these MACEs will be detected (AFTER-2 Study ClinicalTrials.gov number, NCT02354456.)

An epidemiological study to evaluate the use of vitamin K antagonists and new oral anticoagulants among non-valvular atrial fibrillation patients in Turkey- AFTER-2 study design

Objectives: Atrial fibrillation (AF) is one of the most common causes of preventable ischemic stroke and is related to increased cardiovascular morbidity and mortality. There is a lack of data in Turkey on the use of new oral anticoagulants (NOACs), and time in therapeutic INR range (TTR) in vitamin K antagonist users and AF management modality. In this multi-center trial, we aimed to analyze, follow and evaluate the epidemiological data in non-valvular AF patients
