Bacterial and fungal infections may emerge with or following COVID-19 infection. Corticosteroids, antibiotics, and other therapies utilized in severe cases of COVID-19 pneumonia may pose a risk for fungal infections. In this paper, we present the case of a 59-year-old female patient with underlying chronic renal failure and diabetes who received long-term corticosteroid therapy for COVID-19 pneumonia and subsequently developed fungemia and catheter infection due to Candida parapsilosis. We removed her subclavian catheter and administered amphotericin -B therapy for 37 days. Overall, we recommend keeping in mind that opportunistic fungal infections may emerge in patients receiving long-term immunosuppressive drug therapy due to COVID-19 with risk factors such as hemodialysis, central venous catheter use, and broad-spectrum antibiotic use.

Aims: Catheter-related bloodstream infections are important causes of mortality and morbidity. In this study, it was aimed to retrospectively determine the distribution of bacterial factors isolated from intra-catheter blood culture and antibiotic susceptibility rates of patients diagnosed with catheter infection in the intensive care unit of XXXXXXX Training and Research Hospital, Cardiovascular Surgery and Neurosurgery. Methods: In the intensive care unit of XXXXXXX Training and Research Hospital, Cardiovascular Surgery, and Neurosurgery, 79 bacteria isolated from intra-catheter blood cultures of patients diagnosed with catheter infection between January 1, 2021, and December 31, 2022, were included in the study.Antibiotic susceptibility of the factors reproducing in catheter blood culture was obtained from the hospital information system. Antibiotic susceptibilities of bacteria isolated from intra-catheter culture were determined by the disc diffusion method or VITEK-2 automated system. Results: The frequency of factors reproducing from intra-catheter blood culture of patients hospitalized in the intensive care unit of cardiovascular surgery and neurosurgery were Enterococcus spp., Klebsiella pneumoniae, Staphylococcus epidermidis, and Escherichia. coli retrospectively. Klebsiella pneumoniae isolates from intra-catheter blood cultures were resistant to ceftriaxone 75%, piperacillin-tazobactam 25%, amikacin 6.25%, but not to imipenem and meropenem. Antibiotic resistance rates of Staphylococcus aureus isolates isolated from intra-catheter blood cultures were as follows: 100% with penicillin, no resistance to vancomycin. In Escherichia coliisolate isolated from intra-catheter blood cultures, resistance to ceftriaxone was 6.3%, to piperacillin-tazobactam, 12.5%, to imipenem and meropenem, 16.6%, but not to amikacin. Acinetobacter baumanniiisolates isolated from intra-catheter blood culture showed 100% resistance to ceftriaxone, 100% to piperacillin-tazobactam, 85.7% to imipenem, 83.3% to meropenem, and no resistance to amikacin. In the Stenotrophomonas maltophilia isolatesisolated from intra-catheter blood culture, resistance to ceftriaxone, piperacillin-tazobactam, imipenem and meropenem was 100% and levofloxacin was 25%, while no resistance to trimethoprim/sulfamethoxazole was detected. Conclusion: Determining the antibiotic susceptibility of bacteria isolated from catheter culture will contribute to the determination of the appropriate treatment option in the empirical treatment of catheter infections in our hospital and contribute to decreasing in mortality and morbidity rates due to catheter infections.

Tuberculosis is an infectious disease whose diagnosis dates back to very early ages, which still maintains its importance in the world and in our country, can be treated and prevented with preventive (prophylactic) treatment. It is one of the leading causes of death in HIV/AIDS positive patients. Tuberculosis can be seen in two ways, mainly lung tuberculosis and extra-pulmonary tuberculosis. Tuberculosis forms other than lung and laryngeal tuberculosis are not contagious. Today, the HIV epidemic and international migration are the main causes of the increase in the number of tuberculosis cases. In this collected work, lung and non-pulmonary forms of tuberculosis, clinical diagnosis, and current developments in diagnosis are summarized.

Aim: The literature seems to miss the clinical course of COVID-19 infection among the pregnant and its effects on the fetus. The present study aimed to evaluate a total of 21 pregnant inpatients in Ankara Training and Research Hospital with the diagnosis of COVID-19 in terms of symptoms, physical examination findings, laboratory findings, treatment results, and complications. Material and Method: A total of 21 pregnant patients diagnosed with COVID-19 by reverse transcriptase polymerase chain reaction (RT-PCR) in Ankara Training and Research Hospital between 22.04.2020 and 27.09.2021 were included in the study. The clinical symptoms, physical examination findings, laboratory findings, and treatment outcomes of the patients, and the health status of the pregnant and newborn were retrospectively evaluated. Results: Of the 21 pregnant patients, 10 were Turkish citizens, and 11 were foreign nationals. The patients were aged 20-41 years with a mean age of 28.76 years. All patients were unvaccinated. Considering underlying diseases among the patients, it was found that one patient had hypertension, and one patient had thyroid disease. In order of frequency, the symptoms in the patients were cough (n =10), fatigue (n=8), sore throat (n=6), dyspnea (n=5), fever (n=3), myalgia (n=3), joint pain (n=1), and diarrhea (n=1). Physical examinations of the patients yielded a fever of 37.4 °C above in 3 patients and rales in one patient. Although one patient with COVID-19 pneumonia was followed up in the intensive care unit, all were discharged upon recovery. Chloroquine tablets were started in 6 patients, a combination of ritonavir (50 mg) and lopinavir (200 mg) in 4 patients, and favipiravir in one patient. Cesarean section was performed in 9 patients, while 12 patients gave normal delivery. Conclusion: Overall, the clinical course of COVID-19 infection in the pregnant followed up in this study was mild, and all newborns were healthy except for one. It is thought that close follow-ups for the pregnant are needed to minimize complications that may develop in them and their fetuses due to COVID-19 infection. Finally, the COVID-19 vaccine seems to be a must for the pregnant to prevent all possible COVID-related complications.

Objective: We evaluated PCR negativity in oropharyngeal and nasopharyngeal secretions of COVID-19 patients at the end of hydroxychloroquine and/or favipiravir treatments. Methods: Study inclusion criteria were being hospitalized, being older than 18 years, PCR positivity in oropharyngeal and nasopharyngeal secretions and being tested for SARS CoV-2-RNA PCR after treatment. Initially hydroxychloroquine treatment (group 1) was administered to the patients according to COVID-19 guide of Health Ministry. Favipiravir (group 2) alone or in combination with hydroxychloroquine (group 3) was administered to patients who were unresponsive to hydroxychloroquine or had severe pneumonia or were admitted to intensive care unit. Control respiratory specimens were taken no earlier than 24 hours, after the end of therapy. Repeated tests with 24–48-hour intervals were performed in patients with still positive PCR test results. The detection of SARS CoV-2-RNA was made by real-time PCR. Results: The study group included 492 patients who received treatment. Mean duration of symptoms was similar among three groups. PCR negativity rate was 52.8% in the specimens taken 24 hours after the end of treatment. PCR negativity rates was 27.9% (200/492) in 48 hours after the end of treatment, %13.8 (123/492) in 72nd hour and %3.8 (80/492) in 96th hour. The ratios of PCR negativity for all specimen days were similar in three groups. There was no statistically significant difference between the groups for time to PCR negativity from the date of positivity and after the end of treatment. We determined that early or late treatment did not make a difference in terms PCR negativity time. Conclusion: No difference was found in terms of the ratios of PCR negativity or time for negativity in oropharyngeal and/or nasopharyngeal specimens taken after the end of treatment in COVID-19 patients receiving hydroxychloroquine and/or favipiravir treatment.

Introduction: Corynebacterium striatum (C. striatum) is one of the most frequently reported nosocomial infection agents among patients hospitalized in intensive care units following the COVID-19 pandemic. It may cause various opportunistic infections, such as ventilator-associated pneumonia and catheter-associated bloodstream infections, in such patients. The present study attempted to investigate the antibiotic susceptibility of 14 nosocomial infection agent C. striatum strains, isolated from deep tracheal aspirate and blood culture samples of hospitalized patients, for seven different antibiotics (benzylpenicillin, ciprofloxacin, clindamycin, rifampicin, linezolid, tetracycline, and vancomycin). Material and Method: Antibiotic susceptibility of the strains for the mentioned antibiotics was determined utilizing a disk diffusion test in line with the recommendations of the European Antibiotic Susceptibility Committee (EUCAST).Results: While all the isolated C. striatum strains (100%) were resistant to benzylpenicillin, tetracycline, rifampicin, ciprofloxacin, and clindamycin, we found none of them to be resistant to vancomycin and linezolid.Conclusion: Overall, uncovering the antibiotic susceptibility of C. striatum strains isolated from clinical specimens would guide clinicians in deciding on the empirical treatment of hospital-acquired infections led by this agent.

Objectives: The probability of detecting viral and atypical agents in pneumonia patients has increased with the molecular methods used in recent years. We aimed to investigate pneumonia pathogens in endotracheal aspiration samples (ETA) of patients with severe community-acquired (CAP), hospital-acquired pneumonia (HAP), and ventilator-associated pneumonia (VAP) by multiplex polymerase chain reaction (m-PCR) and culture method. Methods: A prospective study was performed between December 2019 and October 2020. Patients 18 years and older with pneumonia followed in ICU on the mechanical ventilator were included. COVID-19 patients were excluded. Patients were grouped as CAP, HAP, and VAP. Two ETA samples were obtained from patients within 48 hours of the pneumonia diagnosis. Respiratory pathogens were investigated in samples by viral-bacterial m-PCR and bacterial culture methods. Results: 74 patients were included in the study. m-PCR of ETA samples achieved pathogen detection in 87.8% of patients compared with 58.1% with culture methods. The most common pathogen detected by m-PCR was Streptococcus pneumoniae in both CAP and HAP patients and Klebsiella spp. in VAP patients. The most common pathogen isolated by culture was Staphylococcus aureus in both CAP and HAP patients and Klebsiella spp. in VAP patients. Atypical pneumonia pathogens were positive for 14.9% of the patients. Atypical pathogens were recovered from 28.5% of CAP patients and 23.1% of HAP patients. Viruses constituted all of the atypical pathogens recovered from HAP patients. No atypical pathogen was found in VAP patients. Conclusion: In this study, S. pneumoniae was the most common pathogen detected with m-PCR, and S. aureus and Klebsiella spp. were the most common pathogens detected with culture. Determination of microbial etiology of lower respiratory tract samples by molecular methods for diagnosing severe CAP and HAP may be beneficial in terms of treatment. Keywords: pneumonia, multiplex PCR, endotracheal aspirate, conventional methods

Aim: In this study, it was aimed to determine the reproducing agents and the antibiotic susceptibility of the agents in a total of 89 urine samples cultured in Ankara Training and Research Hospital, Infectious Diseases and Clinical Microbiology laboratory during the 6-month period between 2021-2022. Material and Method: While growth was detected in urine culture in 68 (76%) of 89 urine samples taken in the study, no growth was found in 21 (24%) of them. Antibiotic susceptibility was studied on Mueller-Hinton agar by the disc diffusion method in isolates with growth in urine culture. Results: Reproducing factors are in order of frequency; 25 E. coli, 17 extended-spectrum beta-lactamase (ESBL) positive E. coli, 10 Klebsiella pneumoniae, 3 Pseudomonas aeruginosa, 3 Proteus mirabilis, 3 Enterococcus faecalis, 1 Enterobacter cloacae, 1 Candida krusei, 1 Staphylococcus aureus, 1 patient E. coli and Proteus species were determined. Resistance rates in E. coli strains isolated from urine culture; 20% (4/20) for ciprofloxacin, 5% (1/19) for nitrofurantoin, 9.5% (2/21) for trimethoprim/ sulfamethoxazole (TMP/SMZ). No resistance was found to fosfomycin 0% (0/19) and to carbapenems (imipenem, meropenem, and ertapenem) (0/21). The resistance rates in ESBL positive E. coli strains are; 100% (13/13) for ciprofloxacin, 7% (1/14) for nitrofurantoin, 12.5% (1/8) for fosfomycin, 26.6% (4/15) for TMP-SMZ. No resistance was found to carbapenems (imipenem, meropenem and ertapenem). Conclusion: In our study, it was determined that the most common infectious agent causing urinary tract infection was E. coli. In our study, it was determined that the resistance rates for ciprofloxacin and TMP-SMZ, which are used in empirical treatment, are high, and the resistance rates for fosfomycin and nitrofurantoin are low in E. coli strains that cause urinary system infection. Due to the low rates of resistance in the empirical treatment of urinary system infections, it would be a suitable approach to prefer oral treatment options such as fosfomycin and nitrofurantoin in outpatients.

Chronic hepatitis B (CHB) is an important public health problem in the world and Turkey. The aim of this study was to evaluate the histological, virological, serological and biochemical response rates in CHB patients receiving tenofovir or entecavir therapy. Control liver biopsies were performed on patients who received tenofovir or entecavir therapy for one year or longer. Histopathological grading was scored according to the modified Knodell system. Eighty-seven CHB patients were included in this study, 56 patients were receiving tenofovir and 31 patients were receiving entecavir therapy. Patients in two treatment groups were similar in terms of baseline parameters (p> 0.05). At the end of the treatment, there was a significant decrease in mean values of HBV DNA, alanine aminotransferase and necroinflammatory scores for both groups (p 0.05). Histological responses were obtained 66.1% from the tenofovir group and 54.8% from the entecavir group. Treatment with tenofovir and entecavir resulted with improvement in Ishak fibrosis scores in 12.5% and 12.9% of the patients, respectively. For 14.3% of the tenofovir-treated patients and for 22.6% of the entecavir-treated patients, the Ishak fibrosis scores worsened. Baseline intermediate/ advanced fibrosis stage (Ishak fibrosis score: 3-6) was found as independent determinant factor on histological response and improvement of fibrosis score (OR= 3.99, p= 0.01; OR= 31.67, p= 0.002; respectively) and treatment duration longer than five years is an independent determinant for improvement of necroinflammatory score (OR= 5.79, p= 0.02). There was no significant difference in the virological, serological, biochemical and, histological responses and improvement of necroinflammatory and fibrosis scores between tenofovir and entecavir groups (p> 0.05). Similar histological, virological, serological and biochemical responses were obtained in patients with CHB receving tenofovir and entecavir treatments. Further studies involving a large number of patients receiving long-term therapy should be done to understand the effects of antiviral treatments on healing of liver histology.

Objective: The purpose of this study is to compare the HHV-8 IgM and IgG positivity rates in patients with different malignancies, including non-Hodgkin lymphoma, Hodgkin’s lymphoma, acute lymphocytic leukemia, acute myelocytic leukemia, multiple myeloma, and chronic myelocytic leukemia. Material and Method: Totally 58 individuals, fifty patients with malignancies and eight healthy individuals were included in the study. Indirect fluorescent an tibody method was used to analyze HHV-8 IgM and HHV-8 IgG antibodies in patient and control groups. Statistical analysis was conducted with SPSS software. Fischer’s Exact Ki-kare test and the Mann-Whitney U-test were used in the statistical evaluation. P values ≤0.05 were considered statistically significant. Findings: In the patient group, 20% of the patients (10/50) were HHV-8 IgM positive. On the other hand, none of the individuals in the control group were HHV-8 IgM positive. In the patient group, 56% of the patients (28/50) were HHV-8 IgG positive, whereas 50% of the individuals (8/16) in the control group were HHV-8 IgG positive. HHV-8 IgM positivity was significantly higher in the patient group when compared to the control group. The highest level of HHV-8 IgM positivity was detected in AML patients, whereas MM patients had the highest level of HHV-8 IgG positivity. Conclusion: HHV-8 IgM and HHV-8 IgG positivity in patients with malignancies can be associated with reactivation or reinfection. Further clinical studies should be carried out on higher number of patients with different malignancies to identify the clinical significance of HHV-8 in these patients.

Objective: In this study, the sensitivity of minocycline, polymyxin B, cholestin and phosphomycin to carbapenem resistant multiresistant Acinetobacter baumannii (A. baumannii) strains (resistant to three or more antibiotic groups) isolated from patients in Ankara Training and Research Hospital It was aimed.Material and Method: Eighty nosocomial A. baumanii strains with a carbapenem resistant multidrug resistance phenotype were included in the study. Sensitivities of minocycline, polymyxin B and phosphomycin were determined by disc diffusion test and colistin susceptibility test by disk diffusion and E-test methods.Results: Eighty (100%) polymyxin B, 75 (93,75%) minocycline sensitive and 4 (5%) medium susceptible to 80 carbapenem resistant A.baumannii strains were evaluated by disc diffusion method. 75 (93.5%) were sensitive to colistin, 5 (6.25%) were moderately sensitive to colistin and 2 (2.5%) were sensitive to phosphomycin. By e-test, all 80 strains (100%) were detected as susceptible to colistin. The MIC range for colistin was 0.125-1.5 μg / ml, the MIC 50 value was 025 μg / ml (the MIC range was found to be 0.5 μg / ml). Conclusion: Polymyxin B and minocycline could be used in therapy because phosphomycin B and susceptibility rates were high in empirical treatment of carbamazepine resistant multispecific A.baumannii strains in our hospital. Phosphomycin could not be used in treatment because of high resistance rate.

Introduction: This study investigated the association and prognostic values of serum C-reactive protein (CRP), procalcitonin (PCT), soluble urokinase plasminogen activator receptor (suPAR), and neopterin levels in patients with ventilator-associated pneumonia (VAP). Materials and Methods: This prospective observational age-and gender-matched study included 38 adult patients who were diagnosed with VAP and 40 adult patients without VAP. The Acute Physiology and Chronic Health Evaluation II (APACHE II), Sequential Organ Failure Assessment (SOFA) and Clinical Pulmonary Infection Scores were calculated, and the daily positive end-expiratory pressure values of the patients were recorded. The serum levels of CRP, PCT, suPAR, and neopterin were measured once in controls (control group) and on days 0, 3, and 5 and at the end of treatment in the VAP group. Results: The CRP, PCT, neopterin, and suPAR levels were significantly higher in the VAP group than in the control group. APACHE II and SOFA values were higher in the VAP group than in the control group. C-reactive protein value on day 0 of >14.5 ng/ml and PCT level on day five of >1.23 ng/ml were 100% specific for the prediction of mortality in the VAP group. Conclusion: Measuring CRP, PCT, neopterin, and suPAR levels may aid in the early diagnosis of VAP in patients hospitalized in the ICU. High CRP and PCT levels, as well as high APACHE II and SOFA scores, may have prognostic value in the follow-up of patients with VAP.
