Infectious and parasitic diseases ,RC109-216 - Abstract
Abstract Background Health care workers' (HCWs) influenza vaccination attitude is known to be negative. The H1N1 epidemic had started in mid 2009 and made a peak in October-November in Turkey. A national vaccination campaign began on November 2nd, 2009. Despite the diligent efforts of the Ministry of Health and NGOs, the attitudes of the media and politicians were mostly negative. The aim of this study was to evaluate whether HCWs' vaccination attitudes improved during the pandemic and to assess the related factors. Methods This cross-sectional survey was carried out at the largest university hospital of the Aegean Region-Turkey. A self-administered questionnaire with 12 structured questions was applied to 807 HCWs (sample coverage 91.3%) before the onset of the vaccination programme. Their final vaccination status was tracked one week afterwards, using immunization records. Factors influencing vaccination rates were analyzed using ANOVA, t-test, chi-square test and logistic regression. Results Among 807 participants, 363 (45.3%) were doctors and 293 (36.6%) nurses. A total of 153 (19.0%) had been vaccinated against seasonal influenza in the 2008-2009 season. Regarding H1N1 vaccination, 143 (17.7%) were willing to be vaccinated vs. 357 (44.2%) unwilling. The number of indecisive HCWs was 307 (38.0%) one week prior to vaccination. Only 53 (11.1%) stated that they would vaccinate their children. Possible side effects (78%, n = 519) and lack of comprehensive field evaluation before marketing (77%, n = 508) were the most common reasons underlying unwillingness or hesitation. Among the 749 staff whose vaccination status could be tracked, 228 (30.4%) actually received the H1N1 vaccine. Some of the 'decided' staff members had changed their mind one week later. Only 82 (60%) of those willing, 108 (37%) of those indecisive and 38 (12%) of those unwilling were vaccinated. Indecisive HCWs were significantly younger (p = 0.017). Females, nurses, and HCWs working in surgical departments were more likely to reject vaccination (p < 0.05). Doctors, HCWs working in medical departments, and HCWs previously vaccinated against seasonal influenza were more likely to accept vaccination (p < 0.05). Being younger than 50 and having been vaccinated in the previous season were important predictors of attitude towards pandemic influenza vaccination. Conclusions Vaccination rates increased substantially in comparison to the previous influenza season. However, vaccination rates could have been even higher since hesitation to be vaccinated increased dramatically within one week (only 60% of those willing and the minority of those indecisive were finally vaccinated). We speculate that this may be connected with negative media at the time.

Aim: Diffuse alveolar hemorrhage syndromes (DAHS) are a group of disease caused by immune and nonimmune disorders with a high morbidity and mortality. Therefore the factors affecting mortality in patients with DAHS are aimed to be evaluated retrospectively in this study. Material and Methods: Totally 24 DAHS cases (12 male, mean age 57.1 ± 18.9 yrs) diagnosed between 1998 and 2007 in our clinic were evaluated according to the patient data. Results: The diagnoses of the patients were ARDS due to DAHS (62.5%), community acquired pneumonia (20.8%) and pulmonary involvement of connective tissue disorders (16.7%). Nine patients had connective tissue disorder (mean disease duration 47.7 ± 54.7 months), 11 patients were on corticosteroid therapy and 5 patients had a history of cytostatic therapy. Only 10 patients (41.7%) had hemoptysis on admission. Hypoxemic respiratory failure was found in 70.8% of the patients and 58.3% of them required invasive mechanical ventilation. Sixteen cases received "pulse" corticosteroid therapy and 13 cases had blood transfusion. During the follow-up, 15 patients (62.5%) developed nosocomial pneumonia and 13 patients (54.2%) died. The patients with a baseline haemoglobin level of 10 gr/dl or less, had higher levels of CRP (20.7 ± 18.0 vs. 11.3 ± 8.0 mg/dl, p= 0.024). The patients died during the follow-up, had shorter duration of symptoms (13.6 ± 15.2 vs. 54.7 ± 81.7 days, p= 0.001) and higher baseline CRP levels (20.6 ± 14.5 vs. 8.6 ± 6.5 mg/dl, p= 0.020). Conclusion: The mortality rate was high in DAHS patients and the baseline CRP level is thought to be important for predicting mortality. [ABSTRACT FROM AUTHOR]

- Abstract
Diabetic foot ulcers (DFUs) are a growing public health problem, paralleling the increasing incidence of diabetes. While prevention is most effective treatment for DFUs, challenge remains on selecting the optimal treatment in cases with DFUs. Health sciences have greatly benefited from the integration of artificial intelligence (AI) applications across various fields. Regarding amputations in DFUs, both literature and clinical practice have mainly focused on strategies to prevent amputation and identify avoidable risk factor. However, there are very limited data on assistive parameters/tools that can be used to determine the level of amputation. This study investigated how well ChatGPT, with its lately released version 4o, matches the amputation level selection of an experienced team in this field. For this purpose, clinical photographs from patients who underwent amputations due to diabetic foot ulcers between May 2023 and May 2024 were submitted to the ChatGPT-4o program. The AI was tasked with recommending an appropriate amputation level based on these clinical photographs. Data from a total of 60 patients were analysed, with a median age of 64.5 years (range: 41-91). According to the Wagner Classification, 32 patients (53.3%) had grade 4 ulcers, 16 patients (26.6%) had grade 5 ulcers, 10 patients (16.6%) had grade 3 ulcers and 2 patients (3.3%) had grade 2 ulcers. A one-to-one correspondence between the AI tool's recommended amputation level and the level actually performed was observed in 50 out of 60 cases (83.3%). In the remaining 10 cases, discrepancies were noted, with the AI consistently recommending a more proximal level of amputation than what was performed. The inter-rater agreement analysis between the actual surgeries and the AI tool's recommendations yielded a Cohen's kappa coefficient of 0.808 (SD: 0.055, 95% CI: 0.701-0.916), indicating substantial agreement. Relying solely on clinical photographs, ChatGPT-4.0 demonstrates decisions that are largely consistent with those of an experienced team in determining the optimal level of amputation for DFUs, with the exception of hindfoot amputations., (© 2024 The Author(s).

- Abstract
Diabetic foot ulcers and infections are complications that can result in significant morbidity such as the need for amputations, especially in uncontrolled diabetes, thereby profoundly impacting quality of life. While traditional treatments like wound care and antibiotics are effective, there is growing interest in the role of micronutrients (such as vitamins C, D, E, zinc and magnesium) in improving outcomes. This study aims to evaluate how these micronutrients affect diabetic foot infections and the need for amputation, offering insights to enhance overall prognosis. Patients who were hospitalised with a diagnosis of diabetic foot infection in the Infectious Diseases Department of Ege University Faculty of Medicine Hospital between 1 April 2022, and 31 January 2023 were included in the study. The patients' socio-demographic information, characteristics of diabetic wounds, operation history, as well as their levels of micronutrients recorded on the case report form. A total of 202 patients were included in the study. The most common micronutrient deficiencies were vitamin D (69%), vitamin C (64%) and zinc (49%). The amputation rates were significantly higher in patients with deficiencies vitamin C, vitamin A and vitamin D (p < 0.005). Our research revealed a significant prevalence of vitamin deficiencies among the participants, and we observed a noteworthy correlation between amputation rates and these deficiencies. Although these findings show promise, it is essential to emphasise that micronutrient supplements should not replace traditional treatments but should rather be considered as a warning sign for preventing complications, particularly amputation or extremity loss., (© 2024 The Author(s).

- Abstract
Bacteria other than Mycobacterium tuberculosis and Mycobacterium leprae are known as nontuberculous mycobacteria (NTM), and the frequency of clinically symptomatic forms is increasing day by day. Mycobacterium fortuitum, a rapidly reproducing NTM, causes various clinical signs such as skin soft-tissue infection, surgical site infection, and disseminated infection in immunosuppressed patients. Although progress can be made in terms of diagnosis when growth is detected in culture, it is quite difficult to distinguish between infection and contamination. There is no place for antituberculosis treatment in the treatment of M. fortuitum. Antibiotics such as quinolones, trimethoprim-sulfamethoxazole, linezolid, doxycycline, clarithromycin, azithromycin, imipenem, tigecycline, linezolid, and amikacin are recommended at least in dual combination therapy. In this case presentation, the diagnosis and treatment of a 2-year skin soft-tissue infection with M. fortuitum growth in culture will be discussed., (Copyright © 2024 Copyright: © 2024 International Journal of Mycobacteriology.)

- Abstract
Background: This study aimed to evaluate the epidemiology of septic shock (SS) associated with intraabdominal infections (IAI) as well as associated mortality and efficacy of early source control in a tertiary-care educational hospital., Methods: Patients who had SS with IAI and consulted by Infectious Diseases consultants between December 2013 and October 2022 during night shifts in our centre were analyzed retrospectively., Results: A total number of 390 patients were included. Overall, 30-day mortality was 42.5% on day 3, while day 14 and 30 mortality rates were 63.3% and 71.3%, respectively. Source control by surgical or percutaneous operation was performed in 123 of 390 cases (31.5%), and the mortality rate was significantly lower in cases that were performed source control at any time during SS (65/123-52.8% vs 213/267-79.8%, p<0.001). In 44 of 123 cases (35.7%), source control was performed during the first 12 hours, and mortality was significantly lower in this group versus others (24/44-54.5% vs 254/346-73.4%, p=0.009). On the other hand, female gender (p<0.001, odds ratio(OR)= 2.943, 95%CI=1.714-5.054), diabetes mellitus (p= 0.014, OR=2.284, 95%CI=1.179-4.424), carbapenem-resistant Gram-negative etiology (p=0.011, OR=4.386, 95%CI=1.398-13.759), SOFA≥10 (p<0.001, OR=3.036, 95%CI=1.802-5.114), lactate >3 mg/dl (p<0.001, OR=2.764, 95%CI=1.562-4.891) and lack of source control (p=0.001, OR=2.796, 95%CI=1.523-5.133) were significantly associated with 30-day mortality in logistic regression analysis., Conclusion: Source control has a vital importance in terms of mortality rates for IAI-related septic shock patients. Our study underscores the need for additional research, as the present analysis indicates that early source control does not manifest as a protective factor in logistic regression., Competing Interests: Competing interests: The authors declare no conflict of Interest.

- Abstract
Severe acute respiratory syndrome coronavirus 2 had devastating consequences for human health. Despite the introduction of several vaccines, COVID-19 continues to pose a serious health risk due to emerging variants of concern. DNA vaccines gained importance during the pandemic due to their advantages such as induction of both arms of immune response, rapid development, stability, and safety profiles. Here, we report the immunogenicity and protective efficacy of a DNA vaccine encoding spike protein with D614G mutation (named pcoSpikeD614G) and define a large-scale production process. According to the in vitro studies, pcoSpikeD614G expressed abundant spike protein in HEK293T cells. After the administration of pcoSpikeD614G to BALB/c mice through intramuscular (IM) route and intradermal route using an electroporation device (ID + EP), it induced high level of anti-S1 IgG and neutralizing antibodies (P < 0.0001), strong Th1-biased immune response as shown by IgG2a polarization (P < 0.01), increase in IFN-γ levels (P < 0.01), and increment in the ratio of IFN-γ secreting CD4
+ (3.78-10.19%) and CD8+ (5.24-12.51%) T cells. Challenging K18-hACE2 transgenic mice showed that pcoSpikeD614G administered through IM and ID + EP routes conferred 90-100% protection and there was no sign of pneumonia. Subsequently, pcoSpikeD614G was evaluated as a promising DNA vaccine candidate and scale-up studies were performed. Accordingly, a large-scale production process was described, including a 36 h fermentation process of E. coli DH5α cells containing pcoSpikeD614G resulting in a wet cell weight of 242 g/L and a three-step chromatography for purification of the pcoSpikeD614G DNA vaccine., (© 2024.

- Abstract
Purpose: Toxoplasma gondii is an obligate intracellular zoonotic parasite that can infect all warm-blooded animals, including humans. Currently, clinical findings of toxoplasmosis are being related to T. gondii strains such as Type I genotype may cause high pathogenicity and Type II genotype causes a milder clinical presentation. We have showed in our previous that Type II genotype is the most frequent strain detected in stray cats and wild birds living in natural life of İzmir. The aim of this study was to assess toxoplasmosis seroprevalence in immunocompromised patients, investigate the presence of T. gondii DNA in their blood samples, and genotype the PCR positive ones., Methods: The 42 buffy-coat and serum samples were collected from immunocompromised patients who were from various clinics. Thereafter, Real-Time PCR targeting RE gene of T. gondii was performed with DNA samples obtained from buffy-coat samples. Genotyping was performed by sequencing of GRA6 and GRA7 gene regions of positive DNA samples obtained from tissues of bioassay and PCR positive samples., Results: According to Real-Time PCR results, T. gondii DNA was detected in 23.8% (10/42) samples. Among these 10 samples, two samples were determined as T. gondii Type II genotype. Anti-Toxoplasma IgG antibodies were detected in 28.57% (12/42) samples., Conclusions: Overall, the detection of Type II genotype in humans in İzmir province suggested that T. gondii infection in humans, stray cats, and wild animals may be associated to each other in terms of transmission., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Indian Association of Medical Microbiologists.

- Abstract
This multicentre (22 centres in Turkey) retrospective cohort study aimed to assess the clinical outcomes of patients with neutropenic fever and SARS-CoV-2 positivity. Study period was 15 March 2020-15 August 2021. A total of 170 cases (58 female, aged 59 ± 15.5 years) that fulfilled the inclusion criteria were included in the study. One-month mortality rate (OMM) was 44.8%. The logistic regression analysis showed the following significant variables for the mentioned dependent variables: (i) achieving PCR negativity: receiving a maximum of 5 days of favipiravir (p = 0.005, OR 5.166, 95% CI 1.639-16.280); (ii) need for ICU: receiving glycopeptide therapy at any time during the COVID-19/FEN episode (p = 0.001, OR 6.566, 95% CI 2.137-20.172), the need for mechanical ventilation (p < 0.001, OR 62.042, 95% CI 9.528-404.011); (iii) need for mechanical ventilation: failure to recover from neutropenia (p < 0.001, OR 17.869, 95% CI 3.592-88.907), receiving tocilizumab therapy (p = 0.028, OR 32.227, 95% CI 1.469-707.053), septic shock (p = 0.001, OR 15.4 96% CI 3.164-75.897), and the need for ICU (p < 0.001, OR 91.818, 95% CI 15.360-548.873), (iv) OMM: [mechanical ventilation (p = 0.001, OR 19.041, 95% CI 3.229-112.286) and septic shock (p = 0.010, OR 5.589,95% CI 1.509-20.700)]. Although it includes a relatively limited number of patients, our findings suggest that COVID-19 and FEN are associated with significant mortality and morbidity., (© 2024. The Author(s).)

- Abstract
Aim: To evaluate the effect of timing of antimicrobial therapy on clinical progress of patients with septic shock., Materials and Method: We included 204 adult patients diagnosed with septic shock according to Sepsis-3 criteria between March 2016 and April 2021. One-month survival was evaluated using univariate and logistic regression analysis., Results: Antibiotic treatment was initiated within 1 h of the vasopressors in 26.4 % of patients. One-month mortality did not differ significantly between patients with and without empirical therapy coverage on etiological agents.

- Abstract
Various clinical outcomes, reinfections, vaccination programs, and antibody responses resulted from the COVID-19 pandemic. This study investigated the time-dependent changes in SARS-CoV-2 antibody responses in infected and/or vaccinated and unvaccinated individuals and to provide insights into spike and nucleocapsid antibodies, which fluctuate during infectious and non-infectious states. This cohort study was carried out at the Ege University Faculty of Medicine hospital in İzmir (western Turkey) and the Erciyes University Faculty of Medicine hospital in Kayseri (central Turkey) between December 2021 and January 2023, which coincided with the second half of COVID-19 pandemic. The study included 100 COVID-19 PCR-positive patients and 190 healthcare workers (HCWs). Antibody levels were followed up via quantitative anti-SARS-CoV-2 spike and qualitative anti-nucleocapsid immunoassays (Elecsys™). Antibody levels declined after infection but persisted for at least 6-8 months. Individuals who had received only CoronaVac had higher anti-nucleocapsid antibody levels in the early months than those who received mixed vaccination. However, anti-spike antibodies persisted longer and at higher levels in individuals who had received mixed vaccinations. This suggests that combining two different vaccine platforms may provide a synergistic effect, resulting in more durable and broad-spectrum immunity against SARS-CoV-2. The study provides information about the vaccination and antibody status of healthcare workers in the second half of the pandemic and provides valuable insights into the dynamics of antibody responses to COVID-19 infection and vaccination.

- Abstract
Cytokine storm is an important cause of death in COVID-19 patients. A recent clinical study showed that administration of recombinant interferon lambda 1 (IFN-λ1 or IL-29) may prevent severe COVID-19. On the other hand, IL-6 has been associated as a prognostic marker of worsening for COVID-19 patients. The objective of this study is to screen IFN-λ1, IL-6 and antibody levels in consecutive serum sample sets of COVID-19 patients. A total of 365 serum samples collected from 208 hospitalized COVID-19 patients were analyzed for IFN-λ1 and IL-6 levels as well as SARS-CoV-2 neutralizing antibodies and anti-S1 IgG antibodies. Analyses of serum samples for cytokine levels showed that IFN-λ1 (>8 pg/mL) and IL-6 (>2 pg/mL) were detected in approximately 64% and 21% patients, respectively. A decrement in IFN-λ1 levels and IL-6 levels above 35 pg/mL can be sign of clinical severity and upcoming dead. An increment in IL-6 levels wasn't detected in every COVID-19 patient but a decrement in IL-6 levels was related to clinical improvement. Importantly, the detection of IFN-λ1 level together with an increase in anti-S1 IgG antibody response were observed in clinically improved patients. Screening severe COVID-19 patients for IFN-λ1, IL-6, and anti-S1 IgG antibody levels during their hospital stay especially in intensive care units may be beneficial to monitor the clinical status and management of treatment strategies. Importantly, detection of IFN-λ1 together with protective IgG antibody response can be an indication of clinical improvement in severe COVID-19 patients and these patients may be discharged from the hospital soon., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

- Abstract
Background: To have country-wide information about multidrug resistance (MDR) in isolates from community-acquired urinary tract infections (CAUTI) of Turkey, in terms of resistance rates and useful options., Methods: We used a geocode standard, nomenclature of territorial units for statistics (NUTS), and a total of 1588 community-acquired isolates of 20 centres from 12 different NUTS regions between March 2019 and March 2020 were analysed., Results: Of the 1588 culture growths, 1269 (79. 9%) were Escherichia coli and 152 (9.6%) were Klebsiella spp. Male sex, advancedage, and having two or more risk factors showed a statistically significant relation with MDR existence (p < 0.001, p: 0.014, p < 0.001, respectively) that increasing number of risk factors or degree of advancing in age directly affects the number of antibiotic groups detected to have resistance by pathogens. In total, MDR isolates corresponded to 36.1% of our CAUTI samples; MDR existence was 35.7% in E. coli isolates and 57.2% in Klebsiella spp. isolates. Our results did not show an association between resistance or MDR occurrence rates and NUTS regions., Discussion: The necessity of urine culture in outpatient clinics should be taken into consideration, at least after evaluating risk factorsfor antibacterial resistance individually. Community-acquired UTIs should be followed up time- and region-dependently. Antibiotic stewardship programmes should be more widely and effectively administrated.

- Abstract
Background: Patients who have performed solid organ transplantation in terms of COVID-19 infection are included in the high-risk group. In this study, it was aimed to evaluate the relationship between vaccination and retrospective evaluation of 32 patients who underwent a heart transplant in the clinic and tested positive for SARS-CoV-2 polymerase chain reaction., Methods: In this study, demographic characteristics of the cases, comorbidities, timing of heart transplantation, immunosuppressive treatments, symptoms of COVID-19 infection, lung imaging findings, follow-up (outpatient/inpatient), treatments, 1-month mortality, and vaccination histories against COVID-19 infection were evaluated. The data obtained from the study were analyzed with SPSS version 25.0., Results: The 3 most common symptoms are cough (37.5%), myalgia (28.1%), and fever (21.8%). COVID-19 infection was severe in 6.2% of the patients, moderate in 37.5%, and mild in 56.2%. Hospitalization was required in 5 patients (15.6%, 1 in the intensive care unit), and the other patients were followed up as an outpatient. Severe COVID-19 infection was seen more in 33% of unvaccinated patients; 93.5% were vaccinated. Nineteen patients (68%) were vaccinated before COVID-19 infection. Our patients received the CoronoVac (Sinovac, China) vaccine., Conclusion: COVID-19 infection is more likely to be severe and mortal in patients with heart transplant recipients. It is also crucial to comply with preventive measures other than immunization in this group of patients. This study is the largest series investigating COVID-19 infection in heart transplant recipient patients in our country., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

- Abstract
Objectives: In this study, we report the immune response to the BNT162b2 vaccine and CoronaVac vaccine after a two-dose vaccination and the effects of conventional drugs, immunosuppressive drugs, and new-generation therapies on vaccine responses in patients with rheumatic and musculoskeletal diseases (RMDs)., Patients and Methods: This is a prospective observational study conducted with 94 patients (65 males, 29 females; mean age: 42.7±12.1 years; range, 19 to 69 years) between May 2021 and January 2022. The immunogenicity of the two-dose regimens of the BNT162b2 and CoronaVac vaccines in adult patients with RMD was analyzed according to disease and treatments. Serum immunoglobulin G antibody levels against SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) spike proteins were measured four weeks after the second dose of vaccines., Results: Patients on regimens including mycophenolate, rituximab, and steroids were less likely to develop an antibody response (p=0.001, p=0.06, and p=0.001, respectively). Impairment of vaccine response by other conventional disease-modifying antirheumatic drugs and by anti-tumor necrosis factor treatments was not shown. Younger participants appeared more likely to develop an antibody response. The CoronaVac vaccine was less likely to develop an antibody response compared to the BNT162b2 vaccine (p=0.002). Systemic lupus erythematosus and vasculitis had the lowest antibody titers compared to other RMDs., Conclusion: Patients receiving mycophenolate mofetil, rituximab, and steroids should be warned about the risk of a suboptimal vaccine response. If possible, vaccination strategies should be changed, and the dose modification of drugs should be made during the vaccination. Further studies are required to determine the responses to SARS-CoV-2 vaccination and optimization of vaccine response in patients with RMDs., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2023, Turkish League Against Rheumatism.)

- Abstract
Comparative validation and clinical performance data are essential for the reliable interpretation of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) antibody test results. This study aimed to assess the performance of six SARS-CoV-2 IgG immunoassays in the context of different disease severities. Four automated chemiluminescence immunoassays (Access [Beckman Coulter], Architect [Abbott], Atellica-IM [Siemens], and Elecsys [Roche]) as well as two ELISA assays (SARS-CoV-2 IgG-S1-based and NCP IgG [Euroimmun]) were evaluated using samples from 143 patients as well as 50 pre-pandemic control serum samples. Accuracy and precision tests were performed for validation purposes. Overall sensitivity ranged between 73.38-88.65% and was higher in spike protein-based assays, while the specificity was ≥98% in all immunoassays. The clinical performance of the immunoassays differed depending on disease severity and target antigen. For instance, the IgG response was lower for samples taken <20 days post-symptom onset (87.30%) compared with those taken ≥20 days post-symptom onset (94.80%). Moreover, moderate disease levels led to the highest levels of IgG. Higher levels of antibodies were detected in the clinically moderate disease group. In asymptomatic and mild groups, more antibody positivity was detected with spike protein-based assays. All the assays tested could be used to detect SARS-CoV-2 IgG. However, spike-based assays revealed relatively higher sensitivity rates than nucleoprotein-based assays, particularly in cases of asymptomatic and mild disease.

- Abstract
Background: In tuberculsosis (TB), miRNA has been used as a biomarker to distinguish between healthy individuals and TB patients. The aim of this study was to investigate (i) the association of the miRNA and cytokine expression levels, the course of tuberculosis infection, clinical forms and response to treatment, and (ii) the effects of genotypic features of bacteria on the course of tuberculosis and the relationship between miRNA and cytokine expressions and bacterial genotypes., Methods: A total of 200 cases (100: culture positive active tuberculosis, 50: quantiferon positive latent tuberculosis infection and 50: quantiferon negative healthy controls) were included in the study. For the tuberculosis group at the time of admission and after treatment, for the latent tuberculosis infection and healthy control groups at the time of admission, miRNA and cytokine expressions were determined. Genotyping of M.tuberculosis isolates was performed by spoligotyping method., Results: While, in the comparison of miRNA expressions between the pretreatment patient group and the healthy control group, there was a statistically significant decrease in the expression of miR-454-3p, miR-15a-5p, miR-590-5p, miR-381, and miR-449a in the Pulmonary TB group, there was no significant change in miRNA expression in extrapulmonary TB patients. When the cytokine expressions of the patient group and the healthy control group were compared before treatment, the expressions of all cytokines in the patient group decreased. However, the only cytokine that showed a significantly lower expression was IL12A in PTB patients., Discussion: There is no significant relationship between the clinical course of the disease, cytokine and miRNA expression, and the genotype of the bacteria.

- Abstract
Candidemia may present as severe and life-threatening infections and is associated with a high mortality rate. This study aimed to evaluate the risk factors associated with 30-day mortality in patients with candidemia. A multi-center prospective observational study was conducted in seven university hospitals in six provinces in the western part of Turkey. Patient data were collected with a structured form between January 2018 and April 2019. In total, 425 episodes of candidemia were observed during the study period. Two hundred forty-one patients died within 30 days, and the 30-day crude mortality rate was 56.7%. Multivariable analysis found that SOFA score (OR: 1.28, CI: 1.154-1.420, p < 0.001), parenteral nutrition (OR: 3.9, CI: 1.752-8.810, p = 0.001), previous antibacterial treatment (OR: 9.32, CI: 1.634-53.744, p = 0.012), newly developed renal failure after candidemia (OR: 2.7, CI: 1.079-6.761, p = 0.034), and newly developed thrombocytopenia after candidemia (OR: 2.6, CI: 1. 057-6.439, p = 0.038) were significantly associated with 30-day mortality. Central venous catheter removal was the only factor protective against mortality (OR: 0.34, CI:0.147-0.768, p = 0.010) in multivariable analysis. Candidemia mortality is high in patients with high SOFA scores, those receiving TPN therapy, and those who previously received antibacterial therapy. Renal failure and thrombocytopenia developing after candidemia should be followed carefully in patients. Antifungal therapy and removing the central venous catheter are essential in the management of candidemia., (© 2021.

- Abstract
The incidence rate of tetanus has dramatically decreased following the discovery of the tetanus vaccine. A decennial booster dose is necessary to maintain the protective antibody levels after the primary vaccination schedule. The recommendations for the tetanus booster doses in adult "people living with acquired immune deficiency virus (HIV)" (PLWH) is similar to those for the general population. However, the duration of protective antibodies in PLWH is unknown. The aim of this study was to determine the factors affecting the response of HIV-infected individuals to tetanus vaccine and to evaluate the role of tetanus antitoxin level in determining the timing of the booster dose. PLWH attending the Adult Vaccination Unit of Ege University Faculty of Medicine Infectious Diseases and Clinical Microbiology Department were tested for tetanus antibodies from 30 October to 30 November 2020. Demographic information and the history of primary vaccination and booster doses were derived from medical files. Tetanus antibodies were detected with "enzyme immunoassay (EIA)" method with Clostridium tetani toxin 5S IgG-"enzyme linked immunosorbent assay (ELISA)" kit (Nova Lisa, Novatec Immundiagnostica, Germany). Antibody levels <0.01 IU/ml were considered negative, 0.01-0.5 IU/ml weak positive, 0.51-1.0 IU/ml positive and > 1.1 IU/ml strong positive. A level ≥ 0.50 IU/ml was considered as protective. The study included 146 PLWH [men (n= 126) and women (n= 40)]. The mean age was 39.5 ± 11.20 years (range: 18-65). Protective antibody level was detected in 114 (78.1%) participants. Receiver operating characteristics (ROC) analysis revealed that the ideal lower limit of CD4+ T cell count during booster vaccination for a person to develop protective antibody level was calculated as ≥ 218 cell/mm3. In the multivariate analysis, it was found that age <50 years (OR= 16.4, 95% CI= 4.9-55.2), the absence of AIDS at the time of diagnosis (OR= 6.7, 95% Cl= 1.05-17.4) and CD4+ T cell count ≥ 218 cells/mm3 at the time of vaccination (OR= 4.2, 95% CI= 1.05-17.4) were associated with protective levels of antibody. Protective levels of tetanus antibodies in PLWH are lower than the general population. It should be considered that the booster dose may be required earlier, especially in PLWH who are > 50 years old, with CD4+ T lymphocyte count <200 cells/mm3 during previous booster vaccination and who had AIDS at the time of the diagnosis.

Aim: Echinococcosis, caused by Echinococcus species, is an important zoonotic disease causing major health problems in humans and animals. Herein, we aimed to evaluate the epidemiology, clinical and laboratory parameters, radiological, serological, pathological, and treatment protocols of followed-up cases of hydatidosis. Methods: A total of 550 patients diagnosed with hydatid cyst disease were included in this study. Patients who were positive for one or more of the enzyme-linked immunosorbent assay or indirect hemagglutination test, pathological results, or radiological findings were examined. The data analyzed were collected from nine centers between 2008 and 2020. Records were examined retrospectively. Results: Among the patients, 292 (53.1%) were women and 258 (46.9%) were men. The patients' mean age was 44.4 ± 17.4 years. A history of living in rural areas was recorded in 57.4% of the patients. A total of 435 (79.1%) patients were symptomatic. The most common symptoms were abdominal pain in 277 (50.4%), listlessness in 244 (44.4%), and cough in 140 (25.5%) patients. Hepatomegaly was found in 147 (26.7%), and decreased breath sounds were observed in 124 (22.5%) patients. Radiological examination was performed in all cases and serological methods were also applied to 428 (77.8%) patients. The most frequently applied serological test was IHA (37.8%). A single cyst has been found in 66% patients. Hepatic involvement occurred in 327 (59.4%), pulmonary involvement was found in 128 (23.3%), whereas both of them were recorded in 43 (7.8%) patients. Splenic involvement was only detected in nine (1.6%) patients. Echinococcus granulosus (72.5%) was most frequently detected. Cyst diameters of 56.9% of the patients were in the range of 5-10 cm. A total of 414 (75.2%) patients received albendazole as an antiparasitic. Mortality was noted in nine (1.6%) patients. Conclusion: Echinococcosis is an important public health problem in Turkey. It can affect the social, economic, and political structures of the community. Public education and awareness are extremely important.

- Abstract
While severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) continues to spread rapidly worldwide, some issues such as the uncertainty of the disease progress, whether intensive care will be needed, and risk classification are still important for clinicians. It is notable that in countries where latent tuberculosis infection (LTBI) is common and participating in the national Bacillus Calmette-Guerin (BCG) vaccination program, the case-fatality rates are relatively low throughout the world. In this study, it was aimed to evaluate the effects of the BCG vaccine and LTBI status on the course of the disease in patients diagnosed with coronavirus-19 (COVID-19) infection and to compare the LTBI rate with people with and without COVID-19 infection. The patients diagnosed with COVID-19 infection who were hospitalized during a period of seven months between May 1st to December 1st, 2020 were investigated by the QuantiFERON-TB Gold Plus (QFT-Plus) test in the blood samples for the presence of LTBI. For the comparison of the patients diagnosed with COVID-19 and people without COVID-19 infections in terms of LTBI rate retrospectively; all consecutive patients who were sent blood samples to the mycobacteriology laboratory for the QFT-Plus test between January 2016 and December 2019 were included in the study. Demographic, clinical, radiological, laboratory, and follow-up data of the patients were obtained from the electronic patient file. A total of 170 patients (n= 9 8 male [57.6%], n= 72 female [42.3%], mean age= 53.5 ± 15.8 years) were enrolled. Twenty-five patients' (25/170 [14.7%]) QFT-plus tests were positive. When the cases with positive QFT-Plus test (n= 25) and the cases with negative QFT-Plus test (n = 145) were compared in terms of disease severity respectively; it was determined that mild/moderate patients were 18/25 (72%) and 108/145 (74.5%), severe patients were 7/25 (28%) and 37/145 (25.5%) (p= 0.988). When these two groups were compared in terms of the clinical course respectively; the need for intensive care was 6/25 (24%) and 34/145 (23.4%) (p= 1.00), oxygen therapy requirement was 13/25 (52%) and 49/145 (33.8%) (p= 0.128), and death was 5/25 (20%) and 18/145 (12.4%) (p= 0.341). QFT-Plus positivity was 25/170 (14.7%) in patients diagnosed with COVID-19, while in control group it was 198/496 (39.9%) (OR= 0.259, 95% CI [0.164-0.411], p<0.001). When the values were evaluated quantitatively, in the COVID-19 patient group, QFT-Plus T1/T2 (IU/ml) interferon (IFN)-ɣ was 0.87 ± 1.52/0.62 ± 1.53, while in the control group it was 1.52 ± 3.69/1.50 ± 3.33 (p= 0.032, p= 0.04). There was no significant difference in the parameters investigated between 82 (48.2%) patients with BCG vaccine and those 88 (51.8%) without BCG vaccine. Although it was not statistically significant in our study, increased oxygen therapy requirement and higher mortality rates in the QFT-Plus positive group were remarkable. The detection of statistically significantly lower LTBI rates and T1-T2/IFN-ɣ values in the COVID-19 group supported that SARS-CoV-2 infection may suppress lymphocyte functions in patients and IFN-ɣ response. We believe that the results of our study are remarkably valuable, but more clinical studies are needed to elucidate the relationship between BCG vaccine, LTBI, and COVID-19 infection.

- Abstract
Aim: Coronavirus Disease 2019 (COVID-19) changed the delivery of medical education in Turkey by moving to an emergency remote teaching system and led to many challenges for future doctors. In this study, we aimed to explore the impact of the COVID-19 pandemic on medical students, to assess their anxiety level and their main anxiety sources related to this pandemic., Methods: A Google Form was distributed to medical students using the virtual snowball sampling method. The form included the Beck Anxiety Inventory and additional 19 questions on sociodemographic characteristics, perceived level of knowledge about the epidemic, self-risk perceptions of COVID-19 and their anxiety levels about some other topics related to COVID-19., Results: Overall, 3105 medical students with a mean age of 22.37 ± 2.46, took the survey. Amongst the participants, only 32% of the students defined their knowledge about the precautions that should be taken during an epidemic disease as acceptable. Students reported highest anxiety level for the continuing spread of COVID-19 in Turkey and transmitting coronavirus to another person. Clinically significant anxiety prevalence was 23.2%. Regression analysis revealed that factors that increased the risk of being anxious included being female, being other than a 5th-year student, thinking that being a medical student would increase the risk of coronavirus transmission or being uncertain about it, being exposed to a patient with COVID-19 or being uncertain about it, being anxious about the continuing spread of COVID-19 in Turkey, being anxious about acquiring COVID-19, being anxious for graduating and being on active duty, being anxious about a medical training interruption., Conclusion: Our results suggest that anxiety is prevalent amongst Turkish medical students during the COVID-19 pandemic and they have a weak preparedness for a pandemic such as COVID-19. Based on our results, new strategies should be implemented for medical education and for alleviating students' anxiety levels., (© 2021 John Wiley & Sons Ltd.)

- Abstract
Background/aim: This study aimed to retrospectively analyse patients with foreign body (FB) injuries in our hospital and to present a patient with missed penetrating sponge FB injury., Materials and Methods: This study lasted 12 years (2008–2020) and reviewed all patients with FB injuries who were admitted to the emergency department (ED) of our hospital. Along with our overall results, we present a case with missed penetrating sponge FB injury in detail., Results: Approximately 377 patients were included in the study (age: 28.3 ± 18.3 years, m/f: 229/148). The foot (n = 148, 39.3%) and the hand (n = 143, 37.9%) were the most frequently injured body parts. Regarding FB types, sewing needles (n = 140, 37.1%), metal pieces (n = 91, 24.1%), and glass (n = 80, 21.2%) were the most frequently observed objects. Most of the patients were injured at home, often by needles or glass. The injury-admission mean time was 7.38 ± 2.5 days. FBs were frequently removed in the ED (n = 176, 46.7%). Plain radiography is the first line in identifying FBs. Soft tissue infection was the most common complication. MRIs were much useful than USGs in detecting the missed penetrating sponge injury of the single patient in the study., Conclusion: For diagnosis of FBs, besides recording the patient’s history, obtaining a two-sided radiogram is of great importance. For nonradiolucent or deeply located FBs, further clinical or radiological investigation must be considered to avoid complications. Although most of the FBs can be removed in the ED, patients may require hospitalisation and operation for FB removal, depending upon FB location and age., Competing Interests: none declared., (This work is licensed under a Creative Commons Attribution 4.0 International License.)

- Abstract
The aim was to evaluate the sensitivity and the possible factors affecting the sensitivity of the QuantiFERON®-TB Gold Plus (QFT-Plus) assay in culture-positive active TB (Tuberculosis) patients, to investigate the possible causes of negative and indeterminate results in active TB patients, and to compare the QFT-Plus results of active TB patients and latent tuberculosis infection (LTBI) cases. The QFT-Plus assay was performed in 46 active TB patients and 64 LTBI. The sensitivity of the test was found as 79.5% in all culture-positive patients, 72.7% in the immunocompromised patients, and 86.4% in the non-immunocompromised patients. Compared to active TB, individuals with LTBI had a lower T-cell response and lower IFN-ɣ concentrations. It was determined that the immunocompromisation reduced the sensitivity of the test and the secreted IFN-ɣ concentrations and increased the indeterminate results in patients with active TB. There was no difference in secreted IFN-ɣ concentrations between M. tuberculosis clones, but higher IFN-ɣ concentrations in patients infected with M. tuberculosis strains compared to patients infected with zoonotic strains. Compared with active TB, response to "only to TB2" was significantly higher in LTBI. In conclusion, it was concluded that TB2 tube increased sensitivity in LTBI but may not contribute to sensitivity in active TB., (© 2021 The Authors. Published by Elsevier Ltd.)

- Abstract
Background/aim: The emergence of the coronavirus disease 2019 (COVID-19) outbreak has had an enormous emotional impact on some vulnerable groups, such as people living with human immunodeficiency virus (HIV) (PLHIV). This study was planned with the aim of assessing the anxiety levels of PLHIV and the sources of their anxiety., Materials and Methods: A web-based questionnaire was sent to PLHIV using the virtual snowball sampling method. The questionnaire included questions about sociodemographic status, information about HIV infection, and the Beck Anxiety Inventory (BAI). Additionally, some opinions of the participants about COVID-19 were asked., Results: A total of 307 respondents, with a median age of 33 years, from 32 different cities, participated in the study. More than half of the respondents reported the belief that COVID-19 was not sufficiently well-known by the medical community and nearly 45% believed that they would have more complications if they contracted COVID-19. One-fourth of the participants had anxiety. Having a preexisting psychiatric disorder, perceiving that they were practicing insufficient preventive measures, not being sure about the presence of any individuals with COVID-19 in their environment, and living with a household member with a chronic disease were found to be the risk factors of PLHIV for having anxiety during this pandemic. The BAI scores were correlated with the patient-reported anxiety levels about the spread of COVID-19 in Turkey, acquiring COVID-19, transmitting COVID-19 to another person, and transmitting HIV to another person. Among the stated conditions, the most common concern was the spread of COVID-19 all over the country, while the least common was transmitting HIV to someone else., Conclusion: The results revealed that a significant proportion of the sample had anxiety, and the findings were essential for developing evidence-based strategies for decreasing the anxiety of PLHIV, especially for those who had risk factors and to provide them with better health care during this pandemic or other pandemic-like crises., Competing Interests: The authors have no conflicts of interest to report., (This work is licensed under a Creative Commons Attribution 4.0 International License.)

- Abstract
Background/aims: Despite surgical advances in liver transplantation and effective prophylactic strategies, posttransplant infections are the most important cause of morbidity and mortality. Diagnosis and management of infections because of developing immunosuppression is difficult and adversely affects mortality. This study aimed to review bacterial and fungal infections in patients after liver transplantation and to reveal the resistance rates., Materials and Methods: A total of 107 patients who underwent liver transplantation between January 2017 and February 2018 were evaluated retrospectively with regard to demographic characteristics, causes of transplantation, conditions that may lead to infection, postoperative infections, pathogens, and resistance patterns., Results: Of the 107 patients who underwent liver transplantation, 48 (44.8%) had an infection. Bacterial infections were detected in 41% of the patients, and fungal infections were found in 13%. When we compared living and cadaveric transplants in terms of infection development, these rates were found to be 53% and 33%, respectively (p=0.034). No statistically significant results could be obtained when evaluating conditions such as sex, presence of underlying primary disease, Model for End-Stage Liver Disease MELD score, diabetes status, total parenteral nutrition, and risk factors for infection., Conclusion: After liver transplantation, infections are often seen in the first month of the postoperative period. Knowing the most common pathogens and resistance states in this process reduces infection-related deaths by providing appropriate treatment regimens at the right time.

- Abstract
Pneumocystis jirovecii is an opportunistic respiratory pathogen causing Pneumocystis pneumonia (PcP) in immunocompromised patients. The aim of this study was to investigate the genetic diversity of P. jirovecii isolates (n: 84) obtained from PcP patients using multilocus sequencing method based on mt26S, SOD, and CYB loci. Among the 84 clinical samples that were positive for P. jirovecii DNA, 31 (36.90%) of them were genotyped using at least one locus. Of the 31 clinical samples, 26 of them were successfully genotyped using all loci whereas three samples were genotyped using either mt26S/CYB loci or mt26S/SOD loci. Additionally, there were two more clinical samples that were genotyped using CYB or SOD locus. Using mt26S locus, genotypes 2, 3, 7, and 8 were detected. Frequencies of genotype 7 and 8 were higher and both of them were found in 11 (n: 29; 37.93%) clinical samples. Using SOD locus, SOD 1, 2, and 4 genotypes were detected. SOD 1 was the predominant genotype (20/28; 71.42%). During the analyses of CYB locus, CYB 1, 2, 5, 6, and 7 as well as a new CYB genotype were detected. CYB 1 (16/29; 55.17%) and 2 (10/29; 34.48%) were the predominant genotypes. Overall, according to the multilocus sequencing results E, F, M, N, P, and V multilocus genotypes were detected among the PcP patients. In addition, SOD 1 was the predominant genotype and CYB had a more polymorphic locus.

- Abstract
Objectives : The aim of the study was to investigate the frequency of tigecycline-associated INR abnormality. Methods : Patients who were hospitalized between June and September 2016 and treated with tigecycline including therapy were extracted from hospital database and retrospectively reviewed. INR values at the beginning and end of treatment were compared. Results : A total of 79 patients who received tigecycline were identified by analyzing the hospital database. Nineteen patients were excluded from the study since INR was not measured at the beginning and/or end of treatment. In 55 of the 60 patients, INR levels were within normal limits (0.9-1.2) at the beginning of treatment while 19 of these 55 (34,5%) had prolonged INR after treatment. Prolongation was found to be mild (1.01-1.25 x ULN-upper limit of normal) in 12 of 19 patients, moderate (1.26-1.5 x ULN) in six and severe (1.51-3.0 x ULN) in one. In 10 of 19 patients, tigecycline was stopped, and the INR values normalized. There was no difference in INR abnormality rate between tigecycline monotherapy versus combination therapy receiving cases (19/27-33% vs. 10/33-30% p:1). Conclusion : These data show that INR prolongation may develop as common as 34.6% during tigecycline therapy. Regular INR follow-up may be beneficial in cases receiving tigecycline.

- Abstract
Background/aims: Ledipasvir (LDV) and sofosbuvir (SOF) as single-tablet regimen (STR) has been approved for treatment of chronic HCV infection (CHC) for treatment-naïve or experienced cirrhotic or non-cirrhotic patients. Our aim was to analyse the effectiveness and safety of 12-24 weeks treatment of LDV/SOF (90mg/400 mg)±ribavirin in a real-life setting in Turkey., Materials and Methods: Between May-Dec 2016, 104 treatment-naïve or experienced adult patients with CHC and with or without cirrhosis (including decompensated cirrhosis) were included in this observational study. Patients were administered LDV/SOF STR± ribavirin once daily for 12 -24 weeks. SVR12 rates and effects of the baseline characteristics on SVR12 rates were assessed., Results: Out of 104 enrolled patients (61.5% female, mean age 62.0 years); 60.6% were cirrhotic, 76.0% previously used peg-IFN, 94.2% had GT1. At the end of the treatment, 77.8% (77/99, no data for 21 patients) had undetectable HCV-RNA and 98.9% (94/95) had SVR12. In the baseline characteristics subgroups, the SVR12 rates varied between 94.4% and 100%, and none of the baseline characteristics had a significant effect on the SVR12 rates. During the study, 6 (5.8%) patients died and none of the deaths was suspected to be related to the LDV/SOF. No treatment-emergent adverse event was reported., Conclusion: In conclusion, LDV/SOF±ribavirin yielded very high SVR12 rates, without any safety or tolerability concern in Turkey. The effectiveness of the LDV/SOF treatment was not affected by the patient demographics or medical characteristics such as fibrosis level, cirrhosis status, previous treatment status, HCV-RNA level or HCV genotype.

- Abstract
Background/aim: Carbapenem-resistant Klebsiella pneumoniae (CR-KP) infections encountered in urology patients differentiate from infections caused by other factors, both in respect to prophylaxis and treatment stage, and require a special approach. We aimed to analyse the predisposing factors and the antibiotherapies for CR-KP infection outbreak in a tertiary urology clinic., Materials and Methods: There were 75 patients in the CR-KP positive group (Group I) and 146 patients in the CR-KP negative group (Group II). Analysis of the predisposing factors for CR-KP infection and comparison of the reinfection rate and the antibiotherapies in the 2 groups were the endpoints., Results: In the first group, age, comorbidity, previous antibiotic use, and nephrostomy tube rates were higher (P = 0.015, P = 0.001, P = 0.004, and P < 0.001, respectively). In the second group, open urological surgery rate, and the proportion of patients presenting with flank pain, lower urinary tract symptoms, and haematuria were higher (P = 0.029, P < 0.001, P < 0.001, and P = 0.007). In the first group, the proportion of patients treated with transurethral bladder tumour resection was higher, whereas, percutaneous nephrolithotomy was higher in the second group (P = 0.045 for both). While hospitalization and Foley catheterization duration were longer in the first group (P < 0.001 for both), double J stent and nephrostomy duration were longer in the second group (P < 0.001 and P = 0.005). Mean leukocyte count at admission was higher in the first group (P < 0.001)., Conclusion: Advanced age, comorbidities, previous antibiotic use, and prolonged Foley catheterization duration are predisposing factors for this infection in the urology department. Two-week administration of combination antibiotic regimens containing carbapenem were effective for the treatment of this infection., Competing Interests: None declared, (This work is licensed under a Creative Commons Attribution 4.0 International License.)

- Abstract
Objectives: Candida species are among the most important causes of hospital acquired blood borne infections, and with high rates of mortality and morbidity, these infections are still a major problem today. History of gastrointestinal surgery, administration of total parenteral nutrition and/or wide spectrum antibiotics and immune suppression following organ transplantations are considered serious risk factors for these infections. This study aimed to evaluate the patients from our general surgery department with diagnosed candidemia; by means of strain, treatment and prognosis., Material and Methods: Patients with positive blood cultures for Candida species who were treated in the wards and Ege University Faculty of Medicine general surgery department of surgical intensive care units of our between 2012 and 2017 were retrospectively analyzed by means of strain, treatment and prognosis., Results: A total of 50 patients were enrolled in the study. Mean age was 58.96 years and 54% of the patients were female. There were nine patients with organ transplantation (four liver and five kidney transplantations), six with intestinal perforation and three with anastomotic leakage. Isolated strains were Candida albicans (36%; 18/50), Candida tropicalis (14%; 7/50), Candida glabrata (12%; 6/50), Candida parapsilosis (8%; 4/50), Candida kefyr (6%; 3/50), Candida krusei (4%; 2/50), Candida pulcherrima (2%; 1/50), Cryptococcus neoformans (2%, 1/50), Geotrichum capitatum (2%, 1/50), Candida spp. (unidentified, 14%; 7/50) with decreasing frequency. The highest antifungal sensitivity rates (> 90%) were measured for amphotericin B, voriconazole and echinocandins among all isolates. One-month mortality rate was 43.4% (20/46). Documented eradication was achieved among 24 of the 33 patients who had control blood culture samples (72.7%), and mean eradication time was 7.6 days. Echocardiography was performed in 14% (7/50) and ophthalmic examination in 8% (4/50)., Conclusion: Although C. albicans appears to be the dominant strain in patients with candidemia, frequencies of other strains are increasing. Early diagnosis and treatment of patients with candidemia is of vital importance due to high mortality and morbidity rates., Competing Interests: Conflict of Interest: The authors have no conflicts of interest to declare., (Copyright © 2019, Turkish Surgical Society.)

- Abstract
Background/aim: Clinicians often neglect fungal infections and do not routinely investigate deep tissue from the wound for fungal culture and sensitivity due to insufficient information in the literature. In this study, we aimed to evaluate fungal etiology of invasive fungal diabetic foot which is rarely reported in the literature., Materials and Methods: The patients who were unresponsive to antibiotic therapy and those with positive fungal in bone or deep tissue culture were enrolled in the study. Detailed hospital records were retrieved for demographics and clinical features., Results: A total of 13 patients who were diagnosed with invasive fungal diabetic foot (ten females, three males, mean age 59.8 ± 9 years) were included. All of the patients had type-2 diabetes mellitus. Eleven (84.6%) patients had mixed infection. The most common cause of fungal infections of diabetic foot ulcers was the Candida species. Ten (76.9%) patients underwent amputation, two (15.4%) patients refused amputation, and one patient died before surgery., Conclusion: Invasive fungal infections may also be a causative pathogen in deep tissue infections. Therefore, fungal pathogens should be considered in patients unresponsive to long-term antibiotic therapy. Early detection of fungal infections in high-risk individuals is critical for the prevention of severe consequences such as foot amputation.

- Abstract
Background/aims: Liver transplantation (LT) is now the standard of care for most end-stage liver diseases. Over the next 30 years, advances in medicine and technology will greatly improve the survival rates of patients after this procedure. The aim of the present study was to analyze retrospectively the results of 1001 patients withLT., Materials and Methods: Medical reports of 989 patients were analyzed retrospectively. Data were obtained from the patient's data chart. Descriptive statistics were used to describe continuous variables (mean, median, and standard deviation)., Results: A total of 1001 LTs for 989 recipients were performed at Ege University Organ Transplantation and Research Center between 1994 and 2017. Therewere 639 male and 350 female recipients. Among 1001 LTs, there were 438 deceased donors and 563 living donors. The age interval of the patients was 4 months to 71 years old. The median Model for End-Stage Liver Disease score was 20. There were 12 deceased liver donors using the split method. There were 12 cases subject to retransplantation. In living donor LT grafts, 423 right lobes, 46 left lobes, and 94 left lateral sectors were used. In the first monitoring,the total annual mortality rate was 130 cases (13%). The mortality rate in retransplantation was found to be 66%. A 1-year survival rate of 87% was generally stablished., Conclusion: LThas been improving consistently over the last two decades. Ege University is one of the biggest liver transplant centers in Turkey for both technical and educational perspective.

- Abstract
Introduction: Tuberculosis is seen generally in the lungs. Besides, all organs in the body can be affected by tuberculosis. Diagnosis of extra pulmonary tuberculosis (EPTB) is more difficult than pulmonary tuberculosis (PTB). Although, the isolation of Mycobacterium tuberculosis is gold standard of diagnosis of EPTB, the rate of bacteriologic isolation is low especially in EPTB. If M. tuberculosis is detected, it gives some information about the epidemiological features of the disease and drug susceptibility., Materials and Methods: In this study, extra pulmonary samples isolated M. tuberculosis in mycobacteriology laboratory were evaluated between 2009-2016. The identification of the genotype of isolated bacteria and drug sensitivity tests were conducted. Spoligotyping was accomplished using a standard technique as described previously., Result: During the study period, M. tuberculosis were cultured in 171 extra pulmonary samples of 165 patients (75 male, 90 female, mean age: 53.35 ± 19.92). Initial direct microscopically examination was revealed M. tuberculosis in 44 patients. There were more than one extra pulmonary organ involvement in six patients. The most common EPTB forms were lymph node TB in 60 patients, pleural tuberculosis in 32 patients and bone tuberculosis in 25 patients. Immunosuppression was detected in 44 (%26.6) patients. Among these, seven patients were infected with HIV. In 21 of 175 samples, drug resistance was detected. Rifampicin resistance in 7 samples, high level isoniazid resistance in 11 samples and rifampicin plus isoniazid resistance (multiply drug resistance) in 6 samples were demonstrated. One hundred thirty-five clinical isolates were cultured from tuberculosis patient's different samples, of which the genetic profile was determined by using Spoligotyping. The major Spoligotypes were T (n= 62; 45.9%), LAM7-TUR (ST41) (n= 11; 8.1%) and H1 (n= 9; 6%) genotypes., Conclusions: The most common EPTB form was lymph node tuberculosis in culture proven patients. In these patients group, multiply drug resistance rate was low (3.6%). Spoligotypes T (45.9%) was detected as most common genetic profile.

- Abstract
Objectives: In this study we retrospectively reviewed A. baumannii meningitis cases treated with tigecycline including regimens and evaluated the efficacy of tigecycline in the therapy., Patients and Methods: Study was performed in seven tertiary-care educational hospitals from five cities of Turkey and one center from France. We extracted data and outcomes of all adult (aged >18) patients with culture proven A. baumannii meningitis treated with tigecycline including antibiotic therapy until April 2016., Results: A total of 23 patients (15 male and eight female) fulfilled our inclusion criteria. All Acinetobacter strains were carbapenem-resistant and susceptible to tigecycline. Six cases received tigecycline monotherapy while 17 received tigecycline including combination therapy (10 with colistin, 4 with netilmicin, 3 with amikacin, 4 with meropenem). Seven of 23 cases (30%) died during the tigecycline including therapy (1 in monotherapy, 4 in colistin, 2 in netilmicin, 1 amikacin, one case received tigecycline + netilmicin followed by tigecycline + colistin). Hence, overall end of treatment (EOT) success was 70%. However, since further 27% died due to additional nosocomial infections, overall clinical success (relieved symptoms at the EOT and one-month post-therapy survival without any relapse or reinfection) decreased to 43%., Conclusion: We conclude that tigecycline may be an alternative in the salvage treatment of nosocomial multidrug-resistant Acinetobacter spp. meningitis.

- Abstract
Background/aim: The aim of this study was to report the clinical characteristics and the treatment outcomes of hand infections in diabetic patients and to review the literature. Materials and methods: The medical records of 17 patients with diabetic hand infections admitted to the Diabetic Foot Care Center of two different clinics from January 2012 to October 2017 were reviewed. To perform the pooled analysis, published series (32 studies) were searched in two international databases (www.scopus.com and www.pubmed.com). Results: Of the 17 patients (mean age 61.7 ± 8.5 years), 8 (47.1%) were female. All cases were type 2 diabetes mellitus. The mean duration of diabetes was 9.0 ± 5.96 years and the mean HbA1c was 7.86 ± 1.88%. There was necrosis in 8 patients (47.1%). The most common causes were injury during saw and hammer use in 5 patients (29.4%) and injury due to inappropriate nail cutting in 3 patients (17.6 %). Nine (52.9%) patients were operated on. No patients underwent any major amputations or died. In 32 publications, 704 patients with diabetic hand infections were found. The average age was 53.43 years (n = 591) and 84.29% of patients (322/382) were found to have type 2 DM. The mean duration of diabetes was 4.12 years (n = 317) and the mean HbA1c was 10.58% (n = 140). The rate of surgical operation was 74.59% (323/433). Conclusion: Diabetic hand injuries often occur when using hand tools such as hammers, saws, and knives, and when cutting nails. It is necessary to use conservative treatment rather than amputation. These patients should consult experienced health care professionals.

- Abstract
Background/aim: It was aimed to evaluate the results of Rose Bengal (RB), ELISA total tests (IgM and IgG), and the Brucella Coombs gel test (BCGT), which are used as screening tests, with the combined results of a tube agglutination test (standard Wright test: SWT) and a tube agglutination test with antihuman globulin (AHG TAT). Materials and methods: Samples from 97 patients prediagnosed with brucellosis (age ≥18 years) were screened with RB, ELISA, and BCGT. SWT < 160 samples and RB-negative but ELISA- or BCGT-positive samples were tested by AHG TAT. SWT ≥ 160 or AHG TAT ≥ 160 was taken as reference. Results: Thirty-two of 56 RB-positive samples and one RB-negative but ELISA- and BCGT-positive sample were found to be ≥160 with SWT or AHG TAT. Sensitivity, specificity, accuracy, and agreement (kappa) values according to SWT ≥ 160 or AHG TAT ≥ 160 positivity were as follows, respectively: RB 96.9%, 62.5%, 74.2%, and 0.509; ELISA total 100%, 60.9%, 74.2%, and 0.515; BCGT test 97%, 70.3%, 79.4%, and 0.594. Conclusion: Sensitivities of the screening tests are similar, but positivities should be confirmed by more specific tests. Positive samples from screening tests should be tested with AHG if the SWT value is <160.
