RESUMO
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.

OBJECTIVE: Neuroimaging abnormalities in central nervous system (CNS) brucellosis are not well documented. The purpose of this study was to evaluate the prevalence of imaging abnormalities in neurobrucellosis and to identify factors associated with leptomeningeal and basal enhancement, which frequently results in unfavorable outcomes. METHODS: Istanbul-3 study evaluated 263 adult patients with CNS brucellosis from 26 referral centers and reviewed their 242 magnetic resonance imaging (MRI) and 226 computerized tomography (CT) scans of the brain. RESULTS: A normal CT or MRI scan was seen in 143 of 263 patients (54.3 %). Abnormal imaging findings were grouped into the following four categories: (a) inflammatory findings: leptomeningeal involvements (44), basal meningeal enhancements (30), cranial nerve involvements (14), spinal nerve roots enhancement (8), brain abscesses (7), granulomas (6), and arachnoiditis (4). (b) White-matter involvement: white-matter involvement (32) with or without demyelinating lesions (7). (c) Vascular involvement: vascular involvement (42) mostly with chronic cerebral ischemic changes (37). (d) Hydrocephalus/cerebral edema: hydrocephalus (20) and brain edema (40). On multivariate logistic regression analysis duration of symptoms since the onset (OR 1.007; 95 % CI 1-28, p = 0.01), polyneuropathy and radiculopathy (OR 5.4; 95 % CI 1.002-1.013, p = 0.044), cerebrospinal fluid (CSF)/serum glucose rate (OR 0.001; 95 % CI 000-0.067, p = 0.001), and CSF protein (OR 2.5; 95 % CI 2.3-2.7, p = 0.0001) were associated with diffuse inflammation. CONCLUSIONS: In this study, 45 % of neurobrucellosis patients had abnormal neuroimaging findings. The duration of symptoms, polyneuropathy and radiculopathy, high CSF protein level, and low CSF/serum glucose rate were associated with inflammatory findings on imaging analyses.

BACKGROUND: We describe the neurological involvement in brucellosis and revisited diagnostic criteria for neurobrucellosis. METHODS: Patients with laboratory-confirmed brucellosis who were consequently hospitalized were observed prospectively in a brucellosis-endemic region. The neurobrucellosis was diagnosed by any one of the following criteria: (1) symptoms and signs consistent with neurobrucellosis; (2) isolation of Brucella species from cerebrospinal fluid (CSF) and/or presence of anti-Brucella antibodies in CSF; (3) the presence of lymphocytosis, increased protein, and decreased glucose levels in CSF; or (4) diagnostic findings in cranial magnetic resonance imaging or CT. RESULTS: Lumbar puncture was performed in 128 laboratory-confirmed brucellosis cases who had neurological symptoms and signs, and 48 (37.5%) were diagnosed as neurobrucellosis. The sensitivity of tube agglutination (TA) in CSF was 0.94, specificity 0.96, positive predictive value 0.94, and negative predictive value 0.96. Brucella bacteria were isolated from CSF in 7 of 48 patients (15%). The mean age of 48 neurobrucellosis patients was 42 years (SD, 19 years), and 16 (33%) were female. The most common neurological findings were agitation (25%), behavioral disorders (25%), muscle weakness (23%), disorientation (21%), and neck rigidity (17%). Cranial nerves were involved in 9 of 48 patients (19%). One patient was left with a sequela of peripheral facial paralysis and 2 patients with sensorineural hearing loss. CONCLUSIONS: Patients with severe and persistent headache and other neurologic symptoms and signs should be considered for neurobrucellosis in endemic regions and to possibly receive longer therapy than 6 weeks. Brucella TA with Coombs test in CSF is sensitive and specific by using a cutoff of ≥1:8.

In this retrospective study, the epidemiologic and clinical characteristics of 105 adult malaria patients, who had been hospitalized between the period of 1992 and 2006 were evaluated. Nineteen percent of the patients were female, and the mean age was 28 +/- 10 years. Fifty percent of the patients acquired the infection in Southeastern Anatolia, while they were on military duty. The most common complaints were rigor (93%), fever (90%), sweating (90%), headache (76%), nausea (45%), and fatigue (38%). The most common physical examination findings were splenomegaly (86%) and hepatomegaly (62%). Anemia was detected in 23%, leukopenia in 47%, thrombocytopenia in 73%, two fold increase in ALT or AST enzyme levels in 32% of the patients. Plasmodium vivax was detected in 101 (96%) patients, whereas P. falciparum was detected in 4 patients (4%). Although the number of malaria cases in Turkey is declining in recent years, the febrile patients with a history of travel to the endemic regions should raise the suspicion of malaria.

BACKGROUND: Crimean Congo hemorrhagic fever (CCHF) is a fatal disease with a mortality rate of 5-30%. CCHF can be asymptomatic or it may progress with bleeding and cause mortality. OBJECTIVES: To evaluate relation of viral load with mortality, clinical and laboratory findings in CCHF. STUDY DESIGN: A total of 126 CCHF patients were included. Serum samples obtained from all patients on admission for measurement of viral load. RESULTS: In our study, mortality rate was 11.1%. The most important prognostic factor was viral load. Mean viral load was 8.3×10(7)copy/ml and 4.6×10(9)copy/ml in survived and dead patients, respectively (p<0.005). Probability of survival is found to be significantly reduced where AST >1130U/l, ALT >490U/l, CPK >505U/l, LDH >980U/l, platelet count <23×10(3)/l, creatinine >1.4mg/dl, INR >1.3, d-dimer >7100ng/dl, and viral load >1.03×10(8)copy/ml. Patients with 10(8)copy/ml or higher viral load had diarrhea, headache, unconsciousness, bleeding, and seizure significantly more frequently (p<0.05). WBC, hemoglobin, platelet counts were significantly lower whereas AST, ALT, CPK, LDH, creatinine levels, PT and aPTT time, d-dimer levels, and INR were found to be significantly higher in these group. CONCLUSIONS: There are several severity criteria for prognosis of CCHF. In addition to these parameters, we introduce creatinine as a predictive factor for prognosis. Our study, which has the largest number of patients among studies that evaluate viral load on CCHF shows that viral load is the most effective parameter on mortality.

BACKGROUND: Knowing risk factors for colistin resistance is important since colistin is the only remaining choice for the treatment of infections caused by multi-drug resistant microorganisms. OBJECTIVE: Evaluate risk factors associated with infection by colistin-resistant microorganisms. DESIGN: Retrospective study. SETTING: Tertiary healthcare centers. PATIENTS AND METHODS: An e-mail including the title and purpose of the study was sent to 1500 infec.tious disease specialists via a scientific and social web portal named "infeksiyon dunyasi (infection world)". Demographic and clinical data was requested from respondents. MAIN OUTCOME MEASURE(S): Colistin-resistance. RESULTS: Eighteen infectious disease specialists from twelve tertiary care centers responded to the invitation data was collected on 165 patients, 56 cases (39.9%) and 109 (66.0%) age- and sex-matched controls. The colistin-resistant microorganisms isolated from cases were 29 Acinetobacter baumannii (51.8%), 18 Pseudomonas aeruginosa (32.1%) and 9 Klebsiella spp. Colistin, carbapenem, and quinolone use in the last three months were risk factors for colistin resistance in the univariate analysis. Previous quinolone use in the last three months (P=.003; RR:3.2; 95% Ci:1.5-6,7) and previous colistin use in the last three months (P=.001; RR: 3.6; 95% CI: 1.63-7.99) were significant risk factors in the multivariate analysis. CONCLUSION: Clinicians should limit the use of quinolones and remain aware of the possibility of resistance developing during colistin use. LIMITATIONS: The lack of a heteroresistance analysis on the isolates. no data on use of a loading dose or the use of colistin in combination.

BACKGROUND/AIM: Broad-spectrum antibiotics have become available for use only with the approval of infectious disease specialists (IDSs) since 2003 in Turkey. This study aimed to analyze the tendencies of doctors who are not disease specialists (non-IDSs) towards the restriction of antibiotics. MATERIALS AND METHODS: A questionnaire form was prepared, which included a total of 22 questions about the impact of antibiotic restriction (AR) policy, the role of IDSs in the restriction, and the perception of this change in antibiotic consumption. The questionnaire was completed by each participating physician. RESULTS: A total of 1906 specialists from 20 cities in Turkey participated in the study. Of those who participated, 1271 (67.5%) had ≤5 years of occupational experience (junior specialists = JSs) and 942 (49.4%) of them were physicians. Specialists having >5 years of occupational experience in their branch expressed that they followed the antibiotic guidelines more strictly than the JSs (P < 0.05) and 755 of physicians (88%) and 720 of surgeons (84.6%) thought that the AR policy was necessary and useful (P < 0.05). CONCLUSION: This study indicated that the AR policy was supported by most of the specialists. Physicians supported this restriction policy more so than surgeons did.

This study aimed to determine the presence of vancomycin resistance (vanA and vanB) and virulence genes (esp, asa1, gelE, ace, hyl, cylA, cpd and ebpA) in vancomycin-resistant Enterococcus faecium (VREfm) strains and to analyse the clonal relationships among the strains. E. faecium strains were identified from rectal and clinical specimens by biochemical tests and the API-20 Strep kit. Susceptibility testing was performed using disc-diffusion and broth-dilution methods. PFGE was used for molecular typing of the VREfm strains. The vancomycin resistance and virulence genes were amplified by two-step multiplex PCR. All 55 VREfm isolates were resistant to penicillin G, ampicillin and high-level gentamicin but were susceptible to quinupristin/dalfopristin and linezolid. Multiplex PCR analysis indicated that all isolates harboured vanA and that 41 (75â%) were positive for virulence genes. The esp gene was the most common virulence factor and was detected in nine (41â%) invasive and 32 (96.7â%) non-invasive isolates. Multiple virulence genes were observed only in two non-invasive isolates; one harboured esp and ebpA and the other harboured esp, ebpA, asa1, gelE and cpd. PFGE typing yielded 16 different types, seven of which were clusters with two to 14 strains each. The clustering rates of the rectal swab, blood and urine isolates were 72.7â%, 61.5â% and 87.5â%, respectively. The genetic similarity observed among the VREfm isolates indicated cross-transmission in the hospital. Further studies on the virulence factors present in the strains might provide insight into the acquisition of these traits and their contribution to increased prevalence of VREfm.

INTRODUCTION: Colistin use has increased over the last ten years because of multidrug-resistant microorganisms. The aim of this study was to compare the clinical and microbiological efficacy of colistin alone or in combination with sulbactam or carbapenem in the treatment of ventilator-associated pneumonia (VAP) due to multidrug-resistant (MDR) and extremely drug-resistant (XDR) A. baumannii. METHODOLOGY: Cases treated for VAP because of MDR and XDR A. baumannii between January 2011 and January 2013 were included in the study. The primary and secondary outcome for colistin alone, colistin with sulbactam, and colistin with carbapenems were evaluated. The primary outcomes were clinical efficacy and microbiological efficacy; the secondary outcomes were nephrotoxicity, length of hospitalization, and mortality. RESULTS: A total of 70 VAP patients were evaluated. A total of 17 patients (24.3%) were administered colistin alone, 20 patients (28.6%) were administered colistin and sulbactam, and 33 patients (47.1%) were administered colistin and carbapenem. Clinical and microbiological response rates were higher in the carbapenem combination group (63.6% and 63.6% in both) than in the sulbactam combination group, which registered 55.0% and 60.0%, respectively. However, this did not represent a significant difference statistically (p > 0.05). There was also no significant difference between colistin alone and the combination groups regarding clinical and microbiological efficacy and mortality. CONCLUSIONS: Neither the administration of colistin alone nor colistin combined with either sulbactam or carbapenem had any noticeable advantage in the treatment of VAP in terms of clinical response, microbiological response, nephrotoxicity, length of hospitalization, and mortality.

OBJECTIVES: To compare the efficacy of colistin (COL) monotherapy versus non-COL based combinations in the treatment of bloodstream infections (BSIs) due to multidrug resistant Acinetobacter spp.(MDR-A). MATERIALS AND METHODS: Retrospective data of 107 MDR-A BSI cases from 27 tertiary centers in Turkey were included. PRIMARY END-POINT: 14-day mortality. SECONDARY END-POINTS: Microbial eradication and clinical improvement. RESULTS: Thirty-six patients in the COL monotherapy (CM) group and 71 in the non-COL based combinations (NCC) group were included in the study. Mean age was 59.98 ± 20 years (range: 18-89) and 50.5% were male. Median duration of follow-up was 40 days (range: 9-297). The 14-day survival rates were 52.8% in CM and 47.23% in NCC group (P = 0.36). Microbiological eradication was achieved in 69% of CM and 83% of NCC group (P = 0.13). Treatment failure was detected in 22.9% of cases in both CM and NCC groups. Univariate analysis revealed that mean age (P = 0.001), Charlson comorbidity index (P = 0.03), duration of hospital stay before MDR-A BSI (P = 0.04), Pitt bacteremia score (P = 0.043) and Acute Physiology and Chronic Health Evaluation II score (P = 0.05) were significant in terms of 14-day mortality. Advanced age (P = 0.01) and duration of hospital stay before MDR-A BSI (P = 0.04) were independently associated with 14-day mortality in multivariate analysis. CONCLUSION: No significant difference was detected between CM and non-COL based combinations in the treatment of MDR-A BSIs in terms of efficacy and 14-day mortality.

BACKGROUND: The Thwaites and Lancet scoring systems have been used in the rapid diagnosis of tuberculous meningitis (TBM). However, brucellar meningoencephalitis (BME) has similar characteristics with TBM. The ultimate aim of this study is to infer data to see if BME should be included in the differential diagnosis of TBM when these two systems suggest the presence of TBM. METHOD: BME and TBM patients from 35 tertiary hospitals were included in this study. Overall 294 adult patients with BME and 190 patients with TBM were enrolled. All patients involved in the study had microbiological confirmation for either TBM or BME. Finally, the Thwaites and Lancet scoring systems were assessed in both groups. RESULTS: The Thwaites scoring system more frequently predicted BME cases (n = 292, 99.3%) compared to the TBM group (n = 182, 95.8%) (P = 0.017). According to the Lancet scoring system, the mean scores for BME and TBM were 9.43 ± 1.71 and 11.45 ± 3.01, respectively (P < 0.001). In addition, TBM cases were classified into "probable" category more significantly compared to BME cases, and BME cases were categorized into the "possible" category more frequently. CONCLUSIONS: When the Thwaites or Lancet scoring systems indicate TBM, brucellar etiology should also be taken into consideration particularly in endemic countries.

BACKGROUND CONTEXT: No direct comparison between brucellar spondylodiscitis (BSD) and tuberculous spondylodiscitis (TSD) exists in the literature. PURPOSE: This study aimed to compare directly the clinical features, laboratory and radiological aspects, treatment, and outcome data of patients diagnosed as BSD and TSD. STUDY DESIGN: A retrospective, multinational, and multicenter study was used. PATIENT SAMPLE: A total of 641 (TSD, 314 and BSD, 327) spondylodiscitis patients from 35 different centers in four countries (Turkey, Egypt, Albania, and Greece) were included. OUTCOME MEASURES: The pre- and peri- or post-treatment spinal deformity and neurologic deficit parameters, and mortality were carried out. METHODS: Brucellar spondylodiscitis and TSD groups were compared for demographics, clinical, laboratory, radiological, surgical interventions, treatment, and outcome data. The Student t test and Mann-Whitney U test were used for group comparisons. Significance was analyzed as two sided and inferred at 0.05 levels. RESULTS: The median baseline laboratory parameters including white blood cell count, C-reactive protein, and erythrocyte sedimentation rate were higher in TSD than BSD (p<.0001). Prevertebral, paravertebral, epidural, and psoas abscess formations along with loss of vertebral corpus height and calcification were significantly more frequent in TSD compared with BSD (p<.01). Surgical interventions and percutaneous sampling or abscess drainage were applied more frequently in TSD (p<.0001). Spinal complications including gibbus deformity, kyphosis, and scoliosis, and the number of spinal neurologic deficits, including loss of sensation, motor weakness, and paralysis were significantly higher in the TSD group (p<.05). Mortality rate was 2.22% (7 patients) in TSD, and it was 0.61% (2 patients) in the BSD group (p=.1). CONCLUSIONS: The results of this study show that TSD is a more suppurative disease with abscess formation requiring surgical intervention and characterized with spinal complications. We propose that using a constellation of constitutional symptoms (fever, back pain, and weight loss), pulmonary involvement, high inflammatory markers, and radiological findings will help to differentiate between TSD and BSD at an early stage before microbiological results are available.

Brucellosis is a zoonotic disease caused by a Gram-negative coccobacillus from the Brucella genus. The disease has a broad spectrum of clinical manifestations. The musculoskeletal system involvement is frequent and, rarely, arthritis can be the only clinical feature of the disease. We report a case of monoarthritis caused by Brucella melitensis.

Crimean-Congo hemorrhagic fever (CCHF) is a viral zoonotic disease that is transmitted primarily through contact with ticks. Nosocomial cases and outbreaks of CCHF have been reported from many countries. Health care workers (HCWs) are at risk of exposure to CCHF. In our study, we evaluated seven HCWs' exposure to confirmed CCHF patients' infected blood and body fluids and prophylactic efficacy of the ribavirin on nosocomial transmission of CCHF retrospectively. Between 2007 and 2013, 150 CCHF cases were admitted to our clinic. During the follow-up of these patients, four doctors and three nurses had contact with infected blood and body fluids through needle stick injury, contact of skin and mucosal surfaces, and probable aerosolization. All of the index cases' diagnoses of CCHF were confirmed during the contact. Ribavirin prophylaxis was administered within 0.5-1 h in six out of seven cases. All of these cases' CCHF virus PCR results were negative. One physician had no contact with infected blood or body fluid, so ribavirin prophylaxis was not administered. The physician developed CCHF and diagnosis was confirmed. Although efficacy of ribavirin for prophylaxis is not clear and very few data exist on prophylactic usage of ribavirin, lack of clinical manifestations in our cases that were given ribavirin compared with the developed clinical manifestations in the physician may be explained by the prophylactic efficacy of the ribavirin.

AIM: To investigate the change of the antibiotic resistance profiles of the nosocomial Acinetobacter baumannii isolates in intensive care units (ICUs) between the years 2008 and 2011. MATERIALS AND METHODS: A. baumannii isolates that were responsible for ICU-acquired nosocomial infections between 2008 and 2011 were included in the study. The susceptibility rates of the antibiotics that are mainly used in the treatment of Acinetobacter infections were compared by years. Clinical and Laboratory Standards Institute criteria were used to determine antimicrobial susceptibility. RESULTS: There were 252 infection episodes detected in 229 hospitalized patients in the ICU that were caused by A. baumannii. Imipenem resistance was found as 98.9% in 2011 whereas it was 54% in 2008. A significant increase was observed for meropenem resistance from 2008 (73.5%) to 2011 (98.9%). Colistin resistance, confirmed by E-test, was found in 4 strains. The resistance rates of other antimicrobial agents were as follows: ampicillin/sulbactam 95.7% and 93.5%, cefoperazone/sulbactam 45.7% and 90.3%, netilmicin 41.7% and 53%, gentamicin 96% and 87.2%, and trimethoprimsulfamethoxazole 91.7% and 72%, in 2008 and 2011, respectively. The resistance rate to tigecycline increased to 81.3% in 2011 from 12.5% in 2008.

Veterinarians and veterinary technicians are at risk for occupational brucellosis. We described the risk factors of occupational brucellosis among veterinary personnel in Turkey. A multicenter retrospective survey was performed among veterinary personnel who were actively working in the field. Of 712 veterinary personnel, 84 (11.8%) had occupational brucellosis. The median number of years since graduation was 7 (interquartile ranges [IQR], 4-11) years in the occupational brucellosis group, whereas this number was 9 (IQR, 4-16) years in the non-brucellosis group (p<0.001). In multivariable analysis, working in the private sector (odds ratio [OR], 2.8; 95% confidence interval [95% CI], 1.55-5.28, p=0.001), being male (OR, 4.5; 95% CI, 1.05-18.84, p=0.041), number of performed deliveries (OR, 1.01; 95% CI, 1.002-1.02, p=0.014), and injury during Brucella vaccine administration (OR, 5.4; 95% CI, 3.16-9.3, p<0.001) were found to be risk factors for occupational brucellosis. We suggest that all veterinary personnel should be trained on brucellosis and the importance of using personal protective equipment in order to avoid this infection.

BACKGROUND: The aim of this study was to delineate mortality indicators in pneumococcal meningitis with special emphasis on therapeutic implications. METHODS: This retrospective, multicenter cohort study involved a 15-year period (1998-2012). Culture-positive cases (n=306) were included solely from 38 centers. RESULTS: Fifty-eight patients received ceftriaxone plus vancomycin empirically. The rest were given a third-generation cephalosporin alone. Overall, 246 (79.1%) isolates were found to be penicillin-susceptible, 38 (12.2%) strains were penicillin-resistant, and 22 (7.1%) were oxacillin-resistant (without further minimum inhibitory concentration testing for penicillin). Being a critical case (odds ratio (OR) 7.089, 95% confidence interval (CI) 3.230-15.557) and age over 50 years (OR 3.908, 95% CI 1.820-8.390) were independent predictors of mortality, while infection with a penicillin-susceptible isolate (OR 0.441, 95% CI 0.195-0.996) was found to be protective. Empirical vancomycin use did not provide significant benefit (OR 2.159, 95% CI 0.949-4.912). CONCLUSIONS: Ceftriaxone alone is not adequate in the management of pneumococcal meningitis due to penicillin-resistant pneumococci, which is a major concern worldwide. Although vancomycin showed a trend towards improving the prognosis of pneumococcal meningitis, significant correlation in statistical terms could not be established in this study. Thus, further studies are needed for the optimization of pneumococcal meningitis treatment.

Malaria is still an important public health problem in the world. Although the number of malaria cases in Turkey has been declining in recent years, the febrile patients with a history of travel to the endemic regions should raise the suspicion of malaria. P. vivax is the most common cause of malaria in Turkey; and those caused by other Plasmodium spp. are imported cases. Since P. falciparum malaria may cause fatal complications, urgent therapy is necessary. We hereby report four falciparum malaria cases with a history of travel to Sudan and Uganda.
