Abstract
There are scarce data on the efficacy of ertapenem in the treatment of bacteremia due to extended-spectrum-beta-lactamase (ESBL)-producing Enterobacterales (ESBL-E) in kidney transplant (KT) recipients. We evaluated the association between treatment with ertapenem or meropenem and clinical cure in KT recipients with nonsevere bacteremic urinary tract infections (B-UTI) caused by ESBL-E. We performed a registered, retrospective, international (29 centers in 14 countries) cohort study (INCREMENT-SOT, NCT02852902). The association between targeted therapy with ertapenem versus meropenem and clinical cure at day 14 (the principal outcome) was studied by logistic regression. Propensity score matching and desirability of outcome ranking (DOOR) analyses were also performed. A total of 201 patients were included; only 1 patient (treated with meropenem) in the cohort died. Clinical cure at day 14 was reached in 45/100 (45%) and 51/101 (50.5%) of patients treated with ertapenem and meropenem, respectively (adjusted OR 1.29; 95% CI 0.51 to 3.22; P = 0.76); the propensity score-matched cohort included 55 pairs (adjusted OR for clinical cure at day 14, 1.18; 95% CI 0.43 to 3.29; P = 0.74). In this cohort, the proportion of cases treated with ertapenem with better DOOR than with meropenem was 49.7% (95% CI, 40.4 to 59.1%) when hospital stay was considered. It ranged from 59 to 67% in different scenarios of a modified (weights-based) DOOR sensitivity analysis when potential ecological advantage or cost was considered in addition to outcome. In conclusion, targeted therapy with ertapenem appears as effective as meropenem to treat nonsevere B-UTI due to ESBL-E in KT recipients and may have some advantages.

Abstract
BACKGROUND Diagnosis of invasive aspergillosis (IA) in patients with hematologic malignancies and under the risk of IA may be uncertain or may delay because of nonspecific clinical presentation of the patients and difficult application techniques of conventional methods. Early diagnosis can provide initial antifungal therapy and prevent high mortality. In this study, we investigated the performance of an Aspergillus lateral-flow device (LFD) test (OLM Diagnostics, Newcastle upon Tyne, United Kingdom) for the diagnosis of IA in pediatric febrile neutropenic patients with hematologic malignancies. METHODS Three hundred and fourty seven serum samples of 26 febrile neutropenic episodes of 21 patients at risk for IA were tested. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of the Aspergillus LFD test at episode level and at serum level were calculated. RESULTS According to the reference diagnostic criteria of IA, one proven and 13 probable IA episodes were defined. Twelve episodes (46.1%) did not meet the criteria for IA. The sensitivity, specificity, PPV, NPV, accuracy of the Aspergillus LFD test at episode level and at serum level were 14.3%, 100%, 100%, 50%, 53.8% and 12.1%, 100%, 100%, 50.8%, 53.9%, respectively. CONCLUSIONS Aspergillus LFD test is an easy-to-use assay with short hands-on time; however, further study of the clinical utility in children and especially in serum samples are needed. It is a highly specific test for IA on bronchoalveolar lavage (BAL) samples but is not useful as a screening test for serum samples unless combined with galactomannan (GM) antigen test because of its potentially suboptimal sensitivity.

Abstract
BACKGROUND Whether active therapy with β-lactam/β-lactamase inhibitors (BLBLI) is as affective as carbapenems for extended-spectrum β-lactamase-producing Enterobacterales (ESBL-E) bloodstream infection (BSI) secondary to urinary tract infection (UTI) in kidney transplant recipients (KTRs) remains unclear. METHODS We retrospectively evaluated 306 KTR admitted to 30 centers from January 2014 to October 2016. Therapeutic failure (lack of cure or clinical improvement and/or death from any cause) at days 7 and 30 from ESBL-E BSI onset was the primary and secondary study outcomes, respectively. RESULTS Therapeutic failure at days 7 and 30 occurred in 8.2% (25/306) and 13.4% (41/306) of patients. Hospital-acquired BSI (adjusted OR [aOR]: 4.10; 95% confidence interval [CI]: 1.50-11.20) and Pitt score (aOR: 1.47; 95% CI: 1.21-1.77) were independently associated with therapeutic failure at day 7. Age-adjusted Charlson Index (aOR: 1.25; 95% CI: 1.05-1.48), Pitt score (aOR: 1.72; 95% CI: 1.35-2.17), and lymphocyte count ≤500 cells/μL at presentation (aOR: 3.16; 95% CI: 1.42-7.06) predicted therapeutic failure at day 30. Carbapenem monotherapy (68.6%, primarily meropenem) was the most frequent active therapy, followed by BLBLI monotherapy (10.8%, mostly piperacillin-tazobactam). Propensity score (PS)-adjusted models revealed no significant impact of the choice of active therapy (carbapenem-containing vs any other regimen, BLBLI- vs carbapenem-based monotherapy) within the first 72 hours on any of the study outcomes. CONCLUSIONS Our data suggest that active therapy based on BLBLI may be as effective as carbapenem-containing regimens for ESBL-E BSI secondary to UTI in the specific population of KTR. Potential residual confounding and unpowered sample size cannot be excluded (ClinicalTrials.gov identifier: NCT02852902).

Abstract
Treatment of carbapenemase-producing Enterobacterales bloodstream infections in solid organ transplant recipients is challenging. The objective of this study was to develop a specific score to predict mortality in solid organ transplant recipients with carbapenemase-producing Enterobacterales bloodstream infections. A multinational, retrospective (2004-2016) cohort study (INCREMENT-SOT, ClinicalTrials.gov NCT02852902) was performed. The main outcome variable was 30-day all-cause mortality. The INCREMENT-SOT-CPE score was developed using logistic regression. The global cohort included 216 patients. The final logistic regression model included the following variables: INCREMENT-CPE mortality score ≥8 (8 points), no source control (3 points), inappropriate empirical therapy (2 points), cytomegalovirus disease (7 points), lymphopenia (4 points), and the interaction between INCREMENT-CPE score ≥8 and CMV disease (minus 7 points). This score showed an area under the receiver operating characteristic curve of 0.82 (95% confidence interval [CI] 0.76-0.88) and classified patients into 3 strata: 0-7 (low mortality), 8-11 (high mortality), and 12-17 (very-high mortality). We performed a stratified analysis of the effect of monotherapy vs combination therapy among 165 patients who received appropriate therapy. Monotherapy was associated with higher mortality only in the very-high (adjusted hazard ratio [HR] 2.82, 95% CI 1.13-7.06, P = .03) and high (HR 9.93, 95% CI 2.08-47.40, P = .004) mortality risk strata. A score-based algorithm is provided for therapy guidance.

Abstract
Clostridioides difficile is the leading cause of healthcare-associated diarrhea and the laboratory diagnosis of Clostridioides difficile infection (CDI) continues to be challenging. Accurate and rapid identification of C. difficile will reduce unnecessary antibiotic use and ensure contact isolation to control the spread of CDI. In this study, diagnostic performance of BD MAX Cdiff assay (Becton Dickinson, USA) was evaluated for the detection of C. difficile in 2502 fresh stool samples from hospitalized children and adult patients and the results were compared to toxigenic culture. The frequency of CDI in adults and pediatric patients were found as 3.3% and 6.2%, respectively. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of BD MAX Cdiff assay were found as; 100%, 99.7%, 93%, and 100% for all patients; 100%, 99.7%, 96.2%, and 100% for pediatric patients; and 100%, 99.6%, 90.2%, and 100% for adult patients, respectively. We concluded that BD MAX Cdiff assay with high sensitivity, specificity, and PPV is useful for the diagnosis of CDI. With a high NPV of 100%, BD MAX Cdiff assay is also suitable for the exclusion of CDI.

Abstract
The clinical use of cytotoxic chemotherapeutic agents has increased survival in cancer patients. However, treatment-associated bone marrow suppression and neutropenia often render patients prone to life-threatening infections. The aim of this study was to evaluate episodes of febrile neutropenia (FN) in patients with solid tumors, and identify the microorganisms and the factors affecting mortality. A total of 100 primary febrile attacks in cancer patients who were followed up at the Department of Oncology of the Akdeniz University Medical Faculty Hospital between January, 2011 and May, 2012, were retrospectively investigated. FN attacks were classified in three groups as follows: Fever of unknown origin, clinically documented infections and microbiologically documented infections. We found that prolonged neutropenia, Multinational Association for Supportive Care in Cancer (MASCC) score <21 and the presence of metastasis increased mortality. We also compared the three groups of infection categories according to mortality rate, but did not observe any significant differences among these groups. Patients with malignancies should be assessed individually during the FN episodes. It is crucial to keep possible infectious pathogens in mind and evaluate the MASCC score, neutropenia duration and metastatic status of the patients, and start empirical antibiotic therapy immediately.

Abstract
Organ transplant recipients under immunosuppressive therapy have a highly increased risk of opportunistic fungal infections. Cutaneous infection caused by Alternaria species are relatively rare in humans and most cases reported in the literature are in immunocompromised individuals. We report here on a 33-year old male renal transplant patient with diabetes mellitus who presented with cutaneous alternariosis caused by Alternaria infectoria, two years after the transplant. The diagnosis was performed by real-time polymerase chain reaction assay and histopathologic examination. The extension of the lesion under itraconazole treatment required treatment consisting of a combination of surgical excision and liposomal amphotericin B.

Abstract
BACKGROUND Because of the emergence and spread of extended-spectrum-beta-lactamase (ESBL)-producing strains which are resistant to many antibiotics, reliable detection of ESBL is very important for infection control. Several chromogenic media have been proposed for the detection of ESBL producers in addition to the conventional phenotypic and genotyping methods. The aim of the present study was to evaluate the performance of Brilliance ESBL agar (Oxoid; Thermo Fisher Scientific, UK), a selective chromogenic agar for the detection of ESBL-producing Escherichia coli (E. coli) and Klebsiella pneumoniae (K. pneumoniae) strains. METHODS A total of 237 strains (143 ESBL producers (76 isolates of E. coli and 67 isolates of K. pneumoniae) and 94 non-ESBL producers (44 isolates of E. coli and 50 isolates of K. pneumoniae)) isolated from various clinical specimens were included in the study. Isolates were identified by conventional methods, Phoenix system (Becton Dickinson, USA), and mass spectrometry. ESBL confirmation was performed by phenotypical tests. A 10 microL aliquot of each isolate's 0.5 McFarland suspension was streaked onto Brilliance ESBL agar. All plates were incubated at 37 degrees C for 24 hours and then were interpreted for growth and colony color according to the manufacturer's recommendations. Identification and ESBL test results were used to calculate the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the medium evaluated at 24 hours. RESULTS The sensitivity, specificity, PPV, and NPV of the medium were 97.9%, 100%, 100%, and 96.9%, respectively, when considering only species specific colored colonies of the isolates. CONCLUSIONS Brilliance ESBL agar could provide a practical alternative to the traditional methods for the identification of ESBL producers.

Abstract
BACKGROUND The aim of this study is to present results of patients who have undergone renal transplantation concurrent with bilateral or unilateral native nephrectomy, with a special focus on polycystic kidney disease (PKD). MATERIAL AND METHODS We presented the outcome of renal transplantation patients who have undergone native nephrectomy unilaterally (n=38) and bilaterally (n=125) and compared the results of patients with PKD and other nephrectomy indications. RESULTS Overall graft survival in the 1st, 3rd, and 5th years were 93%, 90%, and 89%, respectively, in transplantation with concomitant nephrectomy patients. Overall patient survival in the 1st, 3rd, and 5th years were 97%, 94%, and 94%, respectively. Overall surgical complications rate was 17.7% and medical complication rate was 19%. Patients with PKD had more frequent complications. CONCLUSIONS Despite additional surgery, the long-term results of patients with complications were not affected negatively by early diagnosis and treatment. We believe that native nephrectomy concurrent with transplantation can be successfully performed when indicated in selected patients at experienced centers.

Abstract
To show drug interactions between tacrolimus and ertapenem, we retrospectively evaluated 13 renal transplant recipients who had been treated with ertapenem for urinary tract infections during prescription of a constant dose. The mean dose of tacrolimus to achieve desired therapeutic concentrations decreased significantly after beginning ertapenem. The decrease from 0.079 mg/kg to 0.043 mg/kg occurred 2 days after initiation of ertapenem (P < .005). These results suggest that ertapenem, which is not metabolized through the cytochrome (CYP) P450 3A metabolic pathway, interacts with tacrolimus by an unknown mechanism. This report recommends tacrolimus concentration monitoring and dose reductions when the two drugs are administered in combination.

Abstract
PURPOSE Differentiation of Staphylococcus aureus (S. aureus) from coagulase-negative staphylococci is very important in blood stream infections. Identification of S. aureus and coagulase-negative staphylococci (CoNS) from blood cultures takes generally 18-24 h after positive signaling on continuously monitored automated blood culture system. In this study, we evaluated the performance of tube coagulase test (TCT), slide agglutination test (Dry Spot Staphytect Plus), conventional polymerase chain reaction (PCR) and LightCycler Staphylococcus MGrade kit directly from blood culture bottles to achieve rapid identification of S. aureus by using the BACTEC 9240 blood culture system. MATERIALS AND METHODS A total of 129 BACTEC 9240 bottles growing gram-positive cocci suggesting Staphylococci were tested directly from blood culture broths (BCBs) with TCT, Dry Spot Staphytect Plus, conventional PCR and LightCycler Staphylococcus MGrade kit for rapid identification of S. aureus. RESULTS The sensitivities of the tests were 99, 68, 99 and 100%, respectively. CONCLUSION Our results suggested that 2 h TCT was found to be simple and inexpensive method for the rapid identification of S. aureus directly from positive blood cultures.

Abstract
Brucellosis is a zoonosis with a worldwide distribution and remains a significant public health problem mainly in the developing world. In this study we evaluated the in vitro activities and synergistic effects of antibiotic combinations against blood culture isolates of Brucella spp. In vitro susceptibilities of 76 blood culture isolates of Brucella melitensis and one blood culture isolate of Brucella abortus to doxycycline, streptomycin, gentamicin, trimethoprim-sulfamethoxazole, moxifloxacin, rifampin, ciprofloxacin, and tigecycline were examined by Etest method. For 37 patients with Brucella spp. isolates (36 B. melitensis, 1 B. abortus), antibiotic combinations used for treatment were identified with those tested in vitro for synergy using Etest method. Trimethoprim-sulfamethoxazole and tigecycline were the most active of the compounds tested with MIC90 value of 0.094 mg/l. Among antibiotic combinations only streptomycin-rifampin combination was synergistic for one Brucella spp. isolate. The other antibiotic combinations revealed antagonistic or indifferent activity. Complete clinical response was achieved in all patients. Further studies are required to determine the correlation between the antimicrobial susceptibility and synergy test results with the clinical course of patients. Brucellosis can be adequately treated with existing regimens in our region.

Abstract
BACKGROUND Rapid and accurate diagnosis of tuberculosis (TB) is crucial to facilitate early treatment of infectious cases and thus to reduce its spread. To improve the diagnosis of TB, more rapid diagnostic techniques such as antibody detection methods including enzyme-linked immunosorbent assay (ELISA)-based serological tests and immunochromatographic methods were developed. This study was designed to evaluate the validity of an immunochromatographic assay, ICT Tuberculosis test for the serologic diagnosis of TB in Antalya, Turkey. METHODS Sera from 72 patients with active pulmonary (53 smear-positive and 19 smear-negative cases) and eight extrapulmonary (6 smear-positive and 2 smear-negative cases) TB, and 54 controls from different outpatient clinics with similar demographic characteristics as patients were tested by ICT Tuberculosis test. RESULTS The sensitivity, specificity, and negative predictive value of the ICT Tuberculosis test for pulmonary TB were 33.3%, 100%, and 52.9%, respectively. Smear-positive pulmonary TB patients showed a higher positivity rate for antibodies than smear-negative patients, but the difference was not statistically significant. Of the eight patients with extrapulmonary TB, antibody was detected in four patients. CONCLUSION Our results suggest that ICT Tuberculosis test can be used to aid TB diagnosis in smear-positive patients until the culture results are available.

Abstract
BACKGROUND Many studies associated nosocomial infections with increased hospital costs due to extra days in hospital, staff time, extra investigations and drug treatment. The cost of antibiotic treatment for these infections represents a significant part of hospital expenditure. This prospective observational study was designed to determine the daily antibiotic cost of nosocomial infections per infected adult patient in Akdeniz University Hospital. METHODS All adult patients admitted to the ICUs between January 1, 2000, and June 30, 2003 who had only one nosocomial infection during their stay were included in the study. Infection sites and pathogens, antimicrobial treatment of patient and it's cost were recorded. Daily antibiotic costs were calculated per infected patient. RESULTS Among the 8460 study patients, 817 (16.6%) developed 1407 episodes of nosocomial infection. Two hundred thirty three (2.7%) presented with only one nosocomial infection. Mean daily antibiotic cost was 89.64 dollars. Daily antibiotic cost was 99.02 dollars for pneumonia, 94.32 dollars for bloodstream infection, 94.31 dollars for surgical site infection, 52.37 dollars for urinary tract infection, and 162.35 dollars for the other infections per patient. The treatment of Pseudomonas aeruginosa infections was the most expensive infection treated. Piperacillin-tazobactam and amikacin were the most prescribed antibiotics, and meropenem was the most expensive drug for treatment of the nosocomial infections in the ICU. CONCLUSIONS Daily antibiotic cost of nosocomial infections is an important part of extra costs that should be reduced providing rational antibiotic usage in hospitals.

Abstract
Hepatitis A and hepatitis E are enteric transmitted viral diseases occurring in epidemic and sporadic forms especially in developing countries. Previous studies in Turkey showed that most residents are infected with HAV by the second decade of life. Since HEV is generally transmitted by the same route as HAV we conducted a community-based seroprevalence study for HAV and HEV infection in Ahatli area in Antalya, Turkey where socioeconomic conditions are low. Anti-HAV total immunoglobulin was tested by using a microparticle EIA (Axsym-Abbott Lab). Anti-HEV IgG was assayed by a micro ELISA method (Genelabs-Singapore). Of the 338 sera tested, 112 (33.1%) were positive for anti-HAV total antibody. Anti-HEV IgG was detected in three (0.89%) of the serum samples. Seropositivity rates of HAV in preschool and school children were 19.9% and 43.9% respectively (p < 0.001). No antibody to HEV was detected in preschool children, while the prevalence of anti-HEV IgG was 1.6% in children attending school. Our data showed that seroprevalence of anti-HAV is high among children samples but HEV infection appears to be relatively rare in pediatric age groups.

Abstract
Twenty multidrug-resistant vancomycin-resistant Enterococcus faecium strains of the VanA phenotype were isolated over a 1 year period from five patients in the intensive care unit at the University Hospital of Antalya, Turkey. Molecular investigation showed that these strains belonged to five different pulsotypes and that the vanA gene was carried by a Tn1546-like transposon inserted onto a self-transferable plasmid of approximately 200 kb. One patient was infected by two different strains, suggesting horizontal gene transfer within that patient. This is the first documented outbreak of VRE in Turkey with concomitant spread of plasmid and strains.
