    (Springer, 2020) Diktas, Husrev; Uysal, Serhat; Erdem, Hakan; Cag, Yasemin; Miftode, Egidia; Durmus, Gul; Ulu-Kilic, Aysegul
    We aimed to develop a scoring system for predicting in-hospital mortality of community-acquired (CA) sepsis patients. This was a prospective, observational multicenter study performed to analyze CA sepsis among adult patients through ID-IRI (Infectious Diseases International Research Initiative) at 32 centers in 10 countries between December 1, 2015, and May 15, 2016. After baseline evaluation, we used univariate analysis at the second and logistic regression analysis at the third phase. In this prospective observational study, data of 373 cases with CA sepsis or septic shock were submitted from 32 referral centers in 10 countries. The median age was 68 (51-77) years, and 174 (46,6%) of the patients were females. The median hospitalization time of the patients was 15 (10-21) days. Overall mortality rate due to CA sepsis was 17.7% (n = 66). The possible predictors which have strong correlation and the variables that cause collinearity are acute oliguria, altered consciousness, persistent hypotension, fever, serum creatinine, age, and serum total protein. CAS (%) is a new scoring system and works in accordance with the parameters in third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3). The system has yielded successful results in terms of predicting mortality in CA sepsis patients.

    Daptomycin in the Treatment of Diabetic Foot Infections without Osteomyelitis; A Multicenter Study
    (Bilimsel Tip Yayinevi, 2017) Isikgoz Tasbakan, Meltem; Uysal, Serhat; Komur, Suheyla; Karagoz, Gul; Yapar, Nur; Ozturk, Anil Murat; Sipahi, Oguz Resat
    Introduction: Although diabetic foot infections are polymicrobial, gram-positive microorganisms comprise the majority. Daptomycin is a novel agent in treating infections due to multidrug-resistant gram-positive pathogens. In this multicenter study, the outcomes of the daptomycin treatment were evaluated retrospectively in the treatment of diabetic foot infectious without osteomyelitis. Materials and Methods: Patients with diabetic foot infection without osteomyelitis and who received daptomycin treatment were included into the study. Sociodemographic characteristics of the patients, risk factors for methicillin resistant Staphylococcus aureus (MRSA), antimicrobial treatment, and the data of microbiological and clinical outcomes of the cases were registered in a standard form by eleven centers. Clinical success was defined as a combination of end-of-treatment laboratory parameters, clinical and microbiological responses. Results: A total of 46 patients (30 males, 16 females) were clinically evaluated for the outcome of daptomycin therapy. Mean age was 61.09 +/- 11.82 years (31-81) and mean diabetes duration was 13 +/- 8.2 years. The number of mild, moderate and severe infections identified according to the infection scoring system of the Infectious Diseases Society of America (IDSA) were 12 (26.1%0), 25 (54.3%), and 9 (19.6%) respectively. Duration of daptomycin therapy was 17.5 +/- 9.3 days and overall daptomycin success rate was 82.6% (n= 38). Two patients developed side effects. Conclusion: The clinical success rate of this study which assessed the efficacy of daptomycin in diabetic foot infections was 82.6%. Daptomycin can be safely used even in severe cases having had no success with previous antibiotic therapy.

    Osteomiyeliti Olmayan Diyabetik Ayak İnfeksiyonlarında Daptomisin Tedavisi: Çok Merkezli Çalışma
    (2017) Taşbakan, Meltem Işıkgöz; Uysal, Serhat; Kömür, Süheyla; Karagöz, Gül; Yapar, Nur; Öztürk, Anıl Murat; Sipahi, Oğuz Reşat
    Giriş: Diyabetik ayak infeksiyonları polimikrobiyal infeksiyonlar olmasına karşın, bu olgularda gram-pozitif mikroorganizmalar çoğunlu-ğu oluşturmaktadır. Daptomisin, çoklu ilaca dirençli gram-pozitif patojenler için yeni bir ajandır. Bu çok merkezli çalışmada, daptomisin ile tedavi edilen diyabetik ayak infeksiyonu olan olgular retrospektif olarak değerlendirilmiştir.Materyal ve Metod: Diyabetik ayak infeksiyonu olup osteomiyeliti olmayan ve tedavide daptomisin alan hastalar çalışmaya dahil edildi. Sosyodemografik özellikler, metisiline dirençli Staphylococcus aureus (MRSA) için risk faktörleri ve olguların tedavi verileri standart bir formla kaydedildi. Çalışmaya 11 merkez katıldı. Klinik başarı, tedavi sonu laboratuvar parametreleri ile klinik ve mikrobiyolojik yanıtların bir kombinasyonu olarak tanımlandı.Bulgular: Daptomisin tedavisinin sonunda toplam 46 (30 erkek, 16 kadın) hasta klinik olarak değerlendirildi. Ortalama yaş 61.09 ± 11.82 (31-81) yıl ve ortalama diyabet süresi 13 ± 8.2 yıl idi. “Infectious Diseases Society of America (IDSA)” infeksiyon skorlamasına göre tanımlanan hafif, orta ve şiddetli infeksiyon sayıları sırasıyla 12 (%26.1), 25 (%54.3) ve 9 (%19.6) idi. Daptomisin tedavisinin süresi 17.5 ± 9.3 gün ve genel daptomisin başarı oranı %82.6 (n= 38) idi. İki hastada yan etki gelişti.Sonuç: Diyabetik ayak infeksiyonlarında daptomisin etkinliğini değerlendiren bu çalışmada klinik başarı ortalama %82.6 olarak bulunmuştur. Daptomisinin, daha önceki antibiyotik tedavisi ile başarısız olan ağır olgularda bile güvenli bir şekilde kullanılabileceğini düşünüyoruz.

    Treatment of ventilator-associated pneumonia (VAP) caused by Acinetobacter: results of prospective and multicenter ID-IRI study
    (Springer, 2020) Erdem, Hakan; Cag, Yasemin; Gencer, Serap; Uysal, Serhat; Karakurt, Zuhal; Harman, Rezan; Aslan, Emel
    Ventilator-associated pneumonia (VAP) due to Acinetobacter spp. is one of the most common infections in the intensive care unit. Hence, we performed this prospective-observational multicenter study, and described the course and outcome of the disease. This study was performed in 24 centers between January 06, 2014, and December 02, 2016. The patients were evaluated at time of pneumonia diagnosis, when culture results were available, and at 72 h, at the 7th day, and finally at the 28th day of follow-up. Patients with coexistent infections were excluded and only those with a first VAP episode were enrolled. Logistic regression analysis was performed. A total of 177 patients were included; empiric antimicrobial therapy was appropriate (when the patient received at least one antibiotic that the infecting strain was ultimately shown to be susceptible) in only 69 (39%) patients. During the 28-day period, antibiotics were modified for side effects in 27 (15.2%) patients and renal dose adjustment was made in 38 (21.5%). Ultimately, 89 (50.3%) patients died. Predictors of mortality were creatinine level (OR, 1.84 (95% CI 1.279-2.657); p = 0.001), fever (OR, 0.663 (95% CI 0.454-0.967); p = 0.033), malignancy (OR, 7.095 (95% CI 2.142-23.500); p = 0.001), congestive heart failure (OR, 2.341 (95% CI 1.046-5.239); p = 0.038), appropriate empiric antimicrobial treatment (OR, 0.445 (95% CI 0.216-0.914); p = 0.027), and surgery in the last month (OR, 0.137 (95% CI 0.037-0.499); p = 0.003). Appropriate empiric antimicrobial treatment in VAP due to Acinetobacter spp. was associated with survival while renal injury and comorbid conditions increased mortality. Hence, early diagnosis and appropriate antibiotic therapy remain crucial to improve outcomes.
