Item Comparison Of Ceftazidime-Avibactam Susceptibility Testing Methods Against OXA-48-Like Carrying Klebsiella Blood Stream Isolates(2022) Isler, Burcu; Vatansever, Cansel; Ozer, Berna; Cinar, Gule; Aslan, Abdullah Tarik; Stewart, Adam; Simos, Peter; Falconer, Caitlin; Bauer, Michelle J.; Forde, Brian; Harris, Patrick; Simsek, Funda; Tulek, Necla; Demirkaya, Hamiyet; Menekse, Sirin; Akalinj, Halis; Balkan, Ilker Inanc; Aydin, Mehtap; Tigen, Elif Tukenmez; Demir, Safiye Koculu; Kapmaz, Mahir; Keske, Siran; Dogan, Ozlem; Arabaci, Cigdem; Yagci, Serap; Hazirolan, Gulsen; Bakir, Veli Oguzalp; Gonen, Mehmet; Saltoglu, Nese; Azap, Alpay; Azap, Ozlem; Akova, Murat; Ergonul, Onder; Paterson, David L.; Can, Fusun; 35843111Ceftazidime-avibactam exhibits good in vitro activity against carbapenem resistant Klebsiella carrying OXA-48-like enzymes. We tested two hundred unique carbapenem resistant Klebsiella blood stream isolates (71% with single OXA-48-like carbapenemases, including OXA-48, n = 62; OXA-232, n = 57; OXA-244, n = 17; OXA-181, n = 5) that were collected as part of a multicentre study against ceftazidime-avibactam using Etest (bioMerieux, Marcyl'Etoile, France), 10/4 mg disc (Thermo Fisher) and Sensititre Gram Negative EURGNCOL Plates (Lyophilized panels, Sensititre, Thermo Fisher) with the aim of comparing the performances of the Etest and disc to that of Sensititre. Ceftazidime-avibactam MIC50/90 was 2/> 16 mg/L for the entire collection and was 2/4 mg/L for single OXA-48-like producers. Categorical and essential agreements between the Etest and Sensititre were 100% and 97%, respectively. Categorical agreement between the disc and Sensititre was 100%. Etest and 10/4 mg discs are suitable alternatives to Sensititre for ceftazidime-avibactam sensitivity testing for OXA-48-like producers. (C) 2022 Elsevier Inc.

One hundred eighty-seven patients were recruited. Single OXA-48-like carbapenemases predominated (75%), followed by OXA-48-like/NDM coproducers (16%). OXA-232 constituted 31% of all OXA-48-like carbapenemases and was mainly carried on ST2096. Thirty-day mortality was 44% overall and 51% for ST2096. In the multivariate cox regression analysis, SOFA score and immunosuppression were significant predictors of 30-day mortality and ST2096 had a non-significant effect. All OXA-48-like producers remained susceptible to ceftazidime-avibactam.Item Changes in Antimicrobial Resistance and Outcomes of Health Care-Associated Infections(2021) Aydin, Mehtap; Azak, Emel; Bilgin, Huseyin; Menekse, Sirin; Asan, Ali; Mert, Habibe Tulin Elmaslar Habibe Tulin Elmaslar; Yulugkural, Zerrin; Altunal, Lutfiye Nilsun; Hatipoglu, Cigdem Ataman; Ertem, Gunay Tuncer; Altunok, Elif Sargin; Demirkaya, Melike Hamiyet; Ceviker, Sevil Alkan Sevil Alkan; Akgul, Fethiye; Memis, Zeynep; Konya, Petek; Azap, Alpay; Aydin, Gule; Korkmaz, Derya; Karakoc, Zehra Cagla; Yapar, Derya; Karakecili, Faruk; Gunal, Ozgur; Keske, Siran; Kapmaz, Mahir; Kader, Cigdem; Demirel, Aslihan; Ergonul, Onder; 33586014To describe the change in the epidemiology of health care-associated infections (HAI), resistance and predictors of fatality we conducted a nationwide study in 24 hospitals between 2015 and 2018. The 30-day fatality rate was 22% in 2015 and increased to 25% in 2018. In BSI, a significant increasing trend was observed for Candida and Enterococcus. The highest rate of 30-day fatality was detected among the patients with pneumonia (32%). In pneumonia, Pseudomonas infections increased in 2018. Colistin resistance increased and significantly associated with 30-day fatality in Pseudomonas infections. Among S. aureus methicillin, resistance increased from 31 to 41%.Item Vaccination of adults with heart failure and chronic heart conditions: Expert opinion(2018) Celik, Ahmet; Altay, Hakan; Azap, Alpay; Cavusoglu, Yuksel; Nalbantgil, Sanem; Senol, Esin; Temizhan, Ahmet; Yilmaz, Mehmet Birhan; 30516533
