RESUMEN
OBJECTIVE: Occult hepatitis B infection (OHBI) appears to have a higher prevalence in populations at high risk for hepatitis B virus (HBV) infection with concomitant liver disease. The aim was to assess the prevalence of OHBI in a sample of human immunodeficiency virus -1 positive and HBV surface antigen-negative (HIV-1+/HBsAg-) Turkish patients. METHODS: Ten centres in Turkey were included in the study. Patients were selected on the basis of a power calculation with a known population size of HIV-positive patients and a reported prevalence of OHBI. Gender, age, occupation, place of residence, treatment and clinical status, and laboratory results, including immunodeficiency panel, antibody tests, hemogram, biochemistry, and coagulation studies were evaluated retrospectively. RESULTS: The number of HIV-infected patients followed in these centres was 3172 and the sample population numbered 278. All 278 were HBsAg negative. The mean age of the sample was 37.2 ± 13.1 years and 235 (84.5%) were male. All but one patient (99.6%) had been treated with antiretroviral therapy. Of the 278 patients, 169 (60.6%) were positive for Anti-HBs and 125 (44.8%) were positive for Anti-HBc IgG. HIV RNA was detected in 203/278 (73%) of the patients. Four HBV DNA (1.4%) were diagnosed with OHBI. There was no significant difference in hemogram, hemoglobin or bilirubin concentrations in those with OHBI compared with the other patients. CONCLUSION: In a representative sample of HIV+ patients from 10 Turkish centres, the prevalence of OHBI was found to be 1.4%. In HIV positive patients, it is important to identify those with OHBI for optimal clinical management and prognosis.

Candida species are responsible for 70-90% of invasive fungal infections in the intensive care unit. Early diagnosis and treatment is important in candidemia. Improper diagnosis and treatment increases mortality and morbidity significantly. Because of the late results of blood cultures and low sensitivity of the serological tests when used alone, molecular methods should be investigated in this field. In this study, the results of the Candida real-time polymerase chain reaction (Rt-PCR) test, which was studied from blood culture and whole blood, were compared in patients with high candidemia risk who were followed in the General Surgery Intensive Care and Anesthesiology and Reanimation Unit of Cukurova University Faculty of Medicine. It was aimed to investigate the practical utility of Candida RT-PCR test, which is a rapid diagnosis method in patients with suspected candidemia. In our study, 90 patients with high risk of candidemia according to the criteria determined according to the guidelines were evaluated prospectively. Urine, perineum, axilla, tracheal aspirate culture and two sets of blood cultures were obtained from the patients. Blood sample was also drawn into an ethylenediaminetetraacetic acid (EDTA) tube and stored at -40°C for later Candida Rt-PCR study. In Candida Rt- PCR, species-specific primers were used to distinguish species. Candida score (CS) of the patients was calculated. Forty one (45.5%) of the patients were female and 49 (55.5%) were male. The median age of the patients was 61.5 years. Candida was positive in blood culture in three (3.3%) of the patients included in the study, while Candida Rt-PCR was positive in 17 (18.9%). Candida species detected in the blood culture and Rt-PCR test were compatible with each other. Rt-PCR was significantly more positive (p= 0.006). Candida Rt-PCR positivity was significantly higher in patients receiving total parenteral nutrition (p= 0.028), malignancy (p= 0.021), and history of surgery in the last three months (p=0.003). The difference in CS between patients with PCR positive and PCR negative was statistically significant (p= 0.015). Our study was conducted in a high-risk population for candidemia and the results of Candida Rt-PCR was found to be more positive than blood culture. Rt-PCR positivity and blood culture positivity were associated with high CS. In the light of these data, it was thought that it would be appropriate to use molecular methods in the diagnosis and support them with CS, especially in patients with high risk of candidemia. Considering that blood culture, which is the gold standard for the diagnosis of candidemia, gives late results and is 50% positive, using faster diagnostic methods for candidemia is important to reduce mortality and morbidity. The fast and good results of Candida PCR method have shown that it can be used in diagnosis. However, lack of standardization of primers used in PCR tests may cause false positives. Additional studies are needed in this respect.

Background/aim: HIV infection increase the risk of serious disease resulting from common vaccine-preventable infections. Vaccinations are particularly important for HIV infected adults. We aimed to investigate the immunity rates against measles, mumps, rubella, hepatitis A, B, and tetanus in newly diagnosed HIV patients. Materials and methods: Patients who admitted to outpatient clinics of three centers with newly diagnosed HIV infection, between 1 January 2015 and 31 June 2017 were included. Measles, mumps, rubella, varicella zoster virus, hepatitis A, hepatitis B, and tetanus antibody levels were measured by commercial diagnostic kits. Demographical and laboratory data of the patients were recorded. Results: Five hundred and twenty-three patients were enrolled in the study. Of the patients 87% were male (n = 455) and the mean age was 38 ± 13 years. Serology was available for measles 74.2% (388/523), mumps 73.8% (386/523), rubella 77.8% (407/523), hepatitis A 88.5% (463/523), hepatitis B 97.7% (511/523), tetanus 8.6% (45/523), and VZV 79.9% (418/523). Seropositivity was 82% for measles, 75.6% for mumps, 92.1% for rubella. Of the patients whom all three of the components of the MMR vaccine was tested, 37.7% (127/337) were susceptible at least one and needed the vaccine. Mean age was lower in patients who are nonimmune to measles and mumps (p = 0.008). Younger patients were also nonimmune for hepatitis A, while older patients were nonimmune for hepatitis B. Conclusion: In our study we found that rates of nonimmunity can increase up to one third of the patients even though there is a national vaccination program. Nonimmune individuals should be detected and vaccinated in line with recent guidelines and response should be monitored because of the possibility of impaired immunity and possible suboptimal response. National campaigns can be launched for adult immunization and physicians should be aware of the importance of adult immunization.

BACKGROUND Improper use of antimicrobials can cause adverse drug events and high costs. The purpose of this study was to investigate the frequency and potential drug-drug interactions associated with antimicrobials among hospitalized patients. MATERIAL AND METHODS This study was conducted on the same day in 5 different hospitals in Turkey. We included patients aged ³18 years who received at least 1 antimicrobial drug and at least 1 of any other drug. The Micromedex® online drug reference system was used to control and describe the interactions. Drug interactions were classified as contraindicated, major, moderate, and minor. RESULTS Potential drug-drug interactions with antimicrobials were 26.4% of all interactions. Five (42%) of 12 contraindicated interactions and 61 (38%) of 159 major interactions were with antimicrobials. Quinolones, triazoles, metronidazole, linezolid, and clarithromycin accounted for 173 (25.7%) of 673 prescribed antimicrobials, but were responsible for 141 (92.1%) of 153 interactions. In multivariate analysis, number of prescribed antimicrobials (odds ratio: 2.3001, 95% CI: 1.6237-3.2582), number of prescribed drugs (odds ratio: 1.2008, 95% CI: 1.0943-1.3177), and hospitalization in the university hospital (odds ratio: 1.7798, 95% CI: 1.0035-3.1564) were independent risk factors for developing drug interactions. CONCLUSIONS Due to risk of drug interactions, physicians should be more cautious when prescribing antimicrobials, particularly when prescribing quinolones, linezolid, azoles, metronidazole, and macrolides.

Data in the literature regarding the factors that predict unfavorable outcomes in adult herpetic meningoencephalitis (HME) cases are scarce. We conducted a multicenter study in order to provide insights into the predictors of HME outcomes, with special emphasis on the use and timing of antiviral treatment. Samples from 501 patients with molecular confirmation from cerebrospinal fluid were included from 35 referral centers in 10 countries. Four hundred thirty-eight patients were found to be eligible for the analysis. Overall, 232 (52.9%) patients experienced unfavorable outcomes, 44 died, and 188 survived, with sequelae. Age (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.02 to 1.05), Glasgow Coma Scale score (OR, 0.84; 95% CI, 0.77 to 0.93), and symptomatic periods of 2 to 7 days (OR, 1.80; 95% CI, 1.16 to 2.79) and >7 days (OR, 3.75; 95% CI, 1.72 to 8.15) until the commencement of treatment predicted unfavorable outcomes. The outcome in HME patients is related to a combination of therapeutic and host factors. This study suggests that rapid diagnosis and early administration of antiviral treatment in HME patients are keys to a favorable outcome.

BACKGROUND: Nosocomial infections caused by Carbapenem-resistant Klebsiella pneumoniae (CRKP) are increasing. Our aim in this study was to investigate the risk factors of CRKP infections. MATERIAL/METHODS: A retrospective cohort study was performed between 1 January and 31 December 2012 in ICU patients. Data was taken from the hospital infection control database for CRKP. The clinical samples collected from the patients were tested by an automatized system and disk diffusion. SPSS software v11.5 was used for statistical analysis. RESULTS: Totally, 105 Klebsiella pneumoniae isolates were found in 2012 and the carbapenem resistance rate was 48%. The first episode of infection was taken into risk factor analysis. Of the 98 patients, 61 (62.2%) were male and the mean and median ages were 30.4±29.8 and 25 (0-93). The length of stay was longer in the resistant group (p=0.026). Mortality was 48% in the whole group and similar between groups (p=0.533). There was a relationship between meropenem and third-generation cephalosporin use and resistance (OR 3.244 (1.193-8.819) and OR: 3.590 (1.056-12.209). The other risk factors in univariate analysis were: Immunosuppression OR: 2.186 (1.754-2.724), nasogastric catheter OR: 3.562 (1.317-9.634), peripheral arterial catheter OR: 2.545 (1.027-6.307), and being admitted to the neurosurgical unit OR: 4.324 (1.110-16.842). CONCLUSIONS: Restriction of third-generation cephalosporin and carbapenem use and invasive procedures, along with infection control precautions and disinfection policies, may be effective in reducing the carbapenem resistance in ICUs.

BACKGROUND: HIV and syphilis are sexually transmitted infections with overlapping risk factors, potentially leading to increased HIV transmission and treatment challenges. Understanding the clinical management of syphilis co-infection among people living with HIV is crucial for public health interventions. OBJECTIVE: This retrospective cohort study aimed to assess the prevalence of syphilis co-infection, clinical characteristics, treatment response, and public health implications among people living with HIV in southern Turkey. METHODS: Records of 1352 people living with HIV 18 years and older, followed at a tertiary infectious diseases clinic between 2013 and 2023, were analyzed. Data on demographics, clinical stage of syphilis and HIV/AIDS, laboratory parameters, treatment response, and co-infections were collected. Statistical analyses were performed using SPSS 20.0 software. RESULTS: Among the people living with HIV, 103 (7.6%) were diagnosed with syphilis. Most cases were male (97.1%), with a median age of 33 (IQR 28-49) years. Heterosexual transmission was predominant (60.2%), with a history of condomless sexual intercourse in 90.3% of cases. The majority (88.3%) were asymptomatic with latent syphilis. Syphilis was diagnosed concurrently with HIV in 77.7% of cases. Serological response to syphilis treatment was observed in 46.8% of patients, while 53.2% showed a serofast reaction. Neurosyphilis was rare, diagnosed in only one patient. Co-infections with hepatitis B and C were detected in 3.9% and 1.9% of patients, respectively. CONCLUSION: Syphilis co-infection among people living with HIV is a significant public health concern in southern Turkey. Routine screening for syphilis, along with comprehensive education on sexually transmitted infection prevention, is essential for early detection and optimal management. Further research is needed to improve treatment outcomes and address emerging challenges in HIV-syphilis co-infection management.
RESUMEN
Background: Late presentation for HIV care, continues to be a challenge, leading to increased morbidity, mortality, and society costs. The study aimed to determine the rates of late diagnosis (LD) and patient characteristics in Turkey, utilizing the new definition excluding recently infected. Methods: The study included patients admitted to the hospital between 1998 and 2023, with at least 1 year of follow-up. Patients without a CD4 count at their initial admission were excluded. Two definitions of presentation were used: LD, (CD4<350 cells/mL or AIDS-defining event) and advanced disease (AD), (CD4<200 cells/mL or AIDS-defining event). Individuals with recent evidence of infection were reclassified as "not late". Results: Out of the 914 patients meeting the criteria and the analysis focused on 794 treatment-naïve patients, with 90.6% being male and an average age of 36.0 ± 12.0 years. Using the previous definition, 48.9% were diagnosed as late, while the new definition identified 47.2%. A total of 183 patients (23%) were diagnosed with AD, and 25.9% of the diagnoses occurred during the COVID-19 Pandemic. The rate of LD increased during the pandemic compared to before (55.8% vs 44.2%, p=0.005), as did the rate of AD (30.1% vs 20.6%, p=0.007). There was no significant relationship between gender and LD. Patients with LD were older (median ages were 31 vs 36 in groups, p<0.001), had poorer virological response, higher mortality rates (4.8% vs 1.2%, p=0.003), and shorter survival compared to those without (log rank=0.004). Conclusion: HIV patients with LD have poorer prognosis with older age as well as disruption of health services during the pandemic as risk factors. To improve outcomes, multicenter studies should investigate missed opportunities and specific risk factors in our region, and we should screen at-risk populations, promote awareness among underdiagnosed populations, and advocate testing even in disastrous situations.
RESUMEN
INTRODUCTION: Characteristics of exposure and infection risk, are important in strategy development for infection control among healthcare workers (HCWs). Our objective was to investigate the characteristics of exposure of HCWs to SARS-CoV-2 and determine the risk of COVID-19 development. METHODOLOGY: This is a retrospective single-center cohort study, conducted between March and December 2020. Unvaccinated and exposed HCWs were asked to complete a standard form, including demographic data and characteristics of exposure(s). Exposures were stratified according to national guidelines. STROBE checklist was used. RESULTS: Among a total of 4,385 healthcare workers, 1,483 HCWs (33.8%) with a total of 1,903 exposures to SARS-CoV-2 were identified. Median age was 31 (IQR: 26-40) years and 45.4% were male (N = 673). Following exposure, 78 HCWs became SARS-CoV-2-positive (attack rate: 3.9%) and secondary attack rate was 4/16. In terms of infection, exposure to SARS-CoV-2-positive HCWs posed a greater risk compared to contact with patients (8.9%, [n = 66] vs. 3.8% [n = 12], respectively, p = 0.003). PCR positivity rates were 11.5%, 6.3%, and 8.4% for low, medium, and high-risk contacts (p = 0.152). Median time to infection post-exposure was 7 (IQR: 4-13) days. CONCLUSIONS: Given the attack rates, there was no correlation between risk levels and PCR test positivity rates. There was no difference between HCWs with or without work restrictions, in terms of PCR positivity. Due to feasibility issues, prioritizing universally applied symptom screening and resource control strategies and suspending contact tracing and work restrictions, appear to be safe during high prevalence period.

Background and Aim: In chronic hepatitis B infection, antiviral therapy significantly reduces the incidence of complications. This study aimed to present real-life 12-month effectiveness and safety data for TAF. Materials and Methods: This Pythagoras Retrospective Cohort Study included patients from 14 centers in Turkiye. The study presents 12-month results of 480 patients treated with TAF as initial therapy or after switching from another antiviral drug. Results: The study shows treatment of about 78.1% patients with at least one antiviral agent (90.6% tenofovir disoproxil [TDF]). The rate of undetectable HBV DNA increased in both treatment-experienced and naive patients. In TDF-experienced patients, the rate of alanine transaminase (ALT) normalization increased slightly (1.6%) within 12 months, but the change was not statistically significant (p=0.766). Younger age, low albumin, and high body mass index and cholesterol were identified as risk factors for abnormal ALT after 12 months, but no linear relationship was detected. In TDF-experienced patients, renal and bone function indicators showed significant improvement three months after the transition to TAF and remained stable for 12 months. Conclusion: Real-life data demonstrated effective virological and biochemical responses with TAF therapy. After switching to TAF treatment, gains in kidney and bone functions were achieved in the early period.
RESUMEN
Objective: We aimed to investigate the vaccination status and the risk factors for the intensive care unit (ICU) support need of the laboratory-confirmed breakthrough COVID-19 infection inpatients. Materials and Methods: This multi-center point-prevalence study was conducted on inpatients, divided into two groups as 'fully' and 'partially' vaccinated according to COVID-19 vaccination status. Results: Totally 516 patients were included in the study. The median age was 65 (55-77), and 53.5% (n=276) of the patients were male. Hypertension (41.9%, n=216), diabetes mellitus (DM) (31.8%, n=164), and coronary artery disease (CAD) (16.3%, n=84) were the predominant comorbidities. Patients were divided into two groups ICU (n=196) and non-ICU (n=301). Hypertension (p=0.026), DM (p=0.048), and congestive heart failure (CHF) (p=0.005) were significantly higher in ICU patients and the median age was younger among non-ICU patients (p=0.033). Of patients, 16.9% (n=87) were fully vaccinated, and this group's need for ICU support was statistically significantly lower (p=0.021). Conclusion: We conclude that older age, hypertension, DM, CHF, and being partially vaccinated were associated with the need for ICU support. Therefore, all countries should continuously monitor post-vaccination breakthrough COVID-19 infections to determine the national booster vaccine administration approach that will provide vulnerable individuals the highest protection.
RESUMEN
BACKGROUND: Mucormycosis is an emerging aggressive mold infection. This study aimed to assess the outcome of hospitalized adults with rhino-orbito-cerebral mucormycosis (ROCM). The secondary objective was to identify prognostic factors in this setting. METHODS: This study was an international, retrospective, multicenter study. Patients' data were collected from 29 referral centers in 6 countries. All qualified as "proven cases" according to the EORTC/MSGERC criteria. RESULTS: We included 74 consecutive adult patients hospitalized with ROCM. Rhino-orbito-cerebral type infection was the most common presentation (n = 43; 58.1%) followed by rhino-orbital type (n = 31; 41.9%). Twenty (27%) had acquired nosocomial bacterial infections. A total of 59 (79.7%) patients (16 in combination) received appropriate antifungal treatment with high-doses of liposomal amphotericin B. Fifty-six patients (75.7%) underwent curative surgery. Thirty-five (47.3%) required intensive care unit admission (27; 36.5% under mechanical ventilation). Hospital survival was 56.8%, being reduced to 7.4% in patients with invasive mechanical ventilation. A multivariate binary backward logistic regression model identified confusion at admission (OR 11.48), overlapping hospital-acquired infection (OR 10.27), use of antifungal treatment before diagnosis (OR 10.20), no surgical debridement (OR 5.92), and the absence of prior sinusitis (OR 6.32) were independently associated with increased risk for death. CONCLUSION: Today, ROCM still has high mortality rate. Improving source control, rational therpy, and preventing nosocomial infections may improve survival in this severe infection.

BACKGROUND: The number and proportion of elderly patients living with chronic hepatitis C are expected to increase in the coming years. We aimed to compare the real-world efficacy and safety of direct-acting antiviral treatment in elderly and younger Turkish adults infected with chronic hepatitis C. METHODS: In this multicenter prospective study, 2629 eligible chronic hepatitis C patients treated with direct-acting antivirals between April 2017 and December 2019 from 37 Turkish referral centers were divided into 2 age groups: elderly (≥65 years) and younger adults (<65 years) and their safety was compared between 2 groups in evaluable population. Then, by matching the 2 age groups for demographics and pretreatment risk factors for a non-sustained virological response, a total of 1516 patients (758 in each group) and 1244 patients (622 in each group) from the modified evaluable population and per-protocol population were included in the efficacy analysis and the efficacy was compared between age groups. RESULTS: The sustained virological response in the chronic hepatitis C patients was not affected by the age and the presence of cirrhosis both in the modified evaluable population and per-protocol population (P = .879, P = .508 for modified evaluable population and P = .058, P = .788 for per-protocol population, respectively). The results of the per-protocol analysis revealed that male gender, patients who had a prior history of hepatocellular carcinoma, patients infected with non-genotype 1 hepatitis C virus, and patients treated with sofosbuvir+ribavirin had a significantly lower sustained virological response 12 rates (P < .001, P = .047, P = .013, and P = .025, respectively). CONCLUSION: Direct-acting antivirals can be safely used to treat Turkish elderly chronic hepatitis C patients with similar favorable efficacy and safety as that in younger adults.

BACKGROUND: People who inject drugs (PWID) should be treated in order to eliminate hepatitis C virus in the world. The aim of this study was to compare direct-acting antivirals treatment of hepatitis C virus for PWID and non-PWID in a real-life setting. METHODS: We performed a prospective, non-randomized, observational multicenter cohort study in 37 centers. All patients treated with direct-acting antivirals between April 1, 2017, and February 28, 2019, were included. In total, 2713 patients were included in the study among which 250 were PWID and 2463 were non-PWID. Besides patient characteristics, treatment response, follow-up, and side effects of treatment were also analyzed. RESULTS: Genotype 1a and 3 were more prevalent in PWID-infected patients (20.4% vs 9.9% and 46.8% vs 5.3%). The number of naïve patients was higher in PWID (90.7% vs 60.0%), while the number of patients with cirrhosis was higher in non-PWID (14.1% vs 3.7%). The loss of follow-up was higher in PWID (29.6% vs 13.6%). There was no difference in the sustained virologic response at 12 weeks after treatment (98.3% vs 98.4%), but the end of treatment response was lower in PWID (96.2% vs 99.0%). In addition, the rate of treatment completion was lower in PWID (74% vs 94.4%). CONCLUSION: Direct-acting antivirals were safe and effective in PWID. Primary measures should be taken to prevent the loss of follow-up and poor adherence in PWID patients in order to achieve World Health Organization's objective of eliminating viral hepatitis.

OBJECTIVES: Given the many medications used to treat novel coronavirus disease (COVID-19) and its comorbidities and complications, the risk of drug-drug interactions (DDIs) and resulting patient harm is concerning. This study aimed to shed light on physicians' knowledge of potential DDIs related to COVID-19 treatment, to determine the effect of an information brief about these DDIs on their correct response rates, and to identify factors associated with higher levels of knowledge about these DDIs. METHODS: The knowledge of physicians regarding the clinical significance and intervention of 7 common potential DDIs during COVID-19 treatment was evaluated via an online survey. Using a pretest-posttest design, the physicians completed a multiple-choice questionnaire first using their existing knowledge, then received an information brief about the DDIs and completed the same questionnaire again. Pretest and posttest scores were evaluated and factors affecting correct response rates were determined using correlation, regression, and post-hoc analyzes. RESULTS: A total of 244 physicians participated in the survey, 147 (60.2%) of whom were involved in the treatment of COVID-19 patients. After the information brief, there were significant increases in the number of correct responses for both clinical significance and interventions (p < 0.0001). In comparisons of pretest knowledge, physicians involved in the treatment of COVID-19 patients showed significantly higher correct response rate for interventions compared to physicians who had not treated COVID-19 patients (p = 0.003). Post-hoc analysis to compare pretest correct intervention responses among all medical specialties revealed significant differences between infectious diseases and family practice (mean difference: 1.059; p = 0.005) and between internal medicine and family practice (mean difference: 1.771; p < 0.0001). CONCLUSION: Physicians involved in the treatment of COVID-19 patients had more knowledge regarding clinical significance and appropriate management of potential DDIs than those not involved. Therefore, it may be beneficial to organize trainings and issue guidelines about potential DDIs for physicians during the COVID-19 pandemic.

Covid-19 Pneumonia of SARS-CoV-2 pandemic infection, persists to have high disease burden especially in cancer patients. Increased inflammation and thromboembolic processes are blamed to influence cancer patients more than the others but due to lack of knowledge regarding the pathophysiology of the both the virus itself and the response of the host, more basic and translational disease modeling research is needed to understand Cancer-Covid-19 interaction. In this study, serum samples from the patients, who were hospitalized due to Covid-19 pneumonia, applied to different cancer cells and cytotoxicity, motility, proliferation and gene expression analysis were performed. Serum samples derived from healthy volunteers and the fetal bovine serum that is used regularly in cell culture experiments used as controls. Hospitalized Covid-19 patients who had also cancer, were retrospectively screened, and their clinical course were recorded. Overall 12 Patient (PS) and 4 healthy serums (CS) were included in the experiments. PS applied cells showed increased motility in A549 cells as well as lost cell to cell connection in MCF7 and HCT116 cells, and induced expression of VIM, ZEB1 and SNAIL2 mRNA levels. Eight cancer diagnosed patients who were hospitalized due to Covid-19 between April and September 2020 were also reviewed retrospectively, which 5 of them were dead during SARS-CoV-2 infection. Thorax CT images of the 2 patients showed increased metastatic nodules in the lungs as of January 2021. The results of the study indicate that metastasis may be one of the prolonged consequences of COVID-19 pandemic in cancer sufferers.

BACKGROUND: This study aimed to identify the agents causing community-acquired urinary tract infections (CAUTIs) and their resistance patterns and to investigate risk factors for ESBL production. MATERIAL/METHODS: Patients diagnosed at the Department of Infectious Diseases in the Cukurova University School of Medicine Hospital with CAUTI between January 2006 and April 2007 were included prospectively. Patient data were recorded and the microorganisms and their sensitivity patterns were evaluated by the university's central microbiology laboratory. RESULTS: A total 146 patients with CAUTIs, 109 women and 37 men (mean age: 50.9+/-18.44 years), were included in the study. The most common infectious agents were Escherichia coli (76.9%), Klebsiella pneumoniae (9.2%), Proteus mirabilis (4.1%), and Enterococcus spp. (1.6%). The ciprofloxacin resistance rate for E. coli was 35% and resistance to TMP-SMZ 43%, whereas amikacin resistance was substantially low (3%). Four of 12 K. pneumoniae strains were resistant to ciprofloxacin and 2 to TMP-SMZ. Resistance to amikacin was not found in the K. pneumoniae strains. ESBL production was identified in 25 of the 112 E. coli and K. pneumoniae strains. A history of a UTI within the last 6 months (p=0.029) and a history of frequent UTI (p=0.028) were found to be significant risk factors for ESBL production by univariate analysis. The only independent risk factor was a history of urinary system infection in the past 6 months (p=0.025) according to multivariate regression analysis. CONCLUSIONS: These high resistance rates to antimicrobials and particularly the extremely high rate of ESBL production in CAUTI should be carefully considered.

AIM: To determine the microbiological etiology in critically ill neurosurgical patients with nosocomial meningitis (NM) and to show the impact of Gram-negative rods and the differences between patient characteristics and the clinical and prognostic measures in Gram-negative and Gram-positive meningitis. MATERIAL AND METHODS: In this prospective, single-center study, we reviewed all adult patients hospitalized during a 12-year period and identified pathogens isolated from post-neurosurgical cases of NM. Demographic, clinical, and treatment characteristics were noted from the medical records. RESULTS: Of the 134 bacterial NM patients, 78 were male and 56 were female, with a mean age of 46±15.9 and a median age of 50 (18-80) years. One hundred and forty-one strains were isolated; 82 (58.2%) were Gram-negative, 59 (41.8%) were Grampositive. The most commonly isolated microorganism was Acinetobacter baumannii (34.8%). Comparison of mortality data shows that the patients who have meningitis with Gram-negative pathogens have higher mortality than with Gram-positives (p=0.034). The duration between surgery and meningitis was shorter in Gram-negative meningitis cases compared to others (p=0.045) but the duration between the diagnosis and death was shorter in Gram-positive meningitis cases compared to Gram-negatives (p=0.017). Cerebrospinal fluid protein and lactate levels were higher and glucose level was lower in cases of NM with Gram-negatives (p values were respectively, 0.022, 0.039 and 0.049). CONCLUSION: In NM, Gram-negative pathogens were seen more frequently; A. baumanni was the predominant pathogen; and NM caused by Gram-negatives had worse clinical and laboratory characteristic and prognostic outcome than Gram-positives.

OBJECTIVES: In recent years, carbapenem-resistant Klebsiella pneumoniae (CRKP) have become an important threat to hospitalised patients. This study aimed to identify the genetic mechanisms of carbapenem resistance in CRKP isolated from patients in a Turkish centre. METHODS: During 2013-2014, a total of 98 K. pneumoniae isolated from patients at Çukurova University Balcali Hospital (Adana, Turkey) determined phenotypically as resistant to carbapenems were screened genotypically for the presence of carbapenemase enzymes by multiplex PCR. RESULTS: Of the 98 patients for whom genetic investigation was made, 93 (94.9%) were adults, 56 (57.1%) were male and 81 (82.7%) were diagnosed as infected. The mean and median age were 51.8±20.5years and 55 years (range 1-89 years), respectively. The nosocomial infection rate was 87.8% (86/98). The mortality rate was 41.8% (41/98). Fifty-eight patients (59.2%) were admitted to intensive care units. Of the 12 non-nosocomial infections, 5 (41.7%) originated from the inpatient clinic of the urology department. The mean and median hospital length of stay (LOS) were 20.7±20.8days and 17days (range 0-90 days), respectively. The most common carbapenemase gene detected was blaOXA-48 (74.5%), followed by blaVIM (45.9%) and blaSME (37.8%). The blaNDM gene was detected in 20 isolates (20.4%). The most effective antibiotics were tigecycline and colistin, with susceptibility rates of 87.5% and 74.3%, respectively. CONCLUSIONS: Multiple resistance mechanisms were present in CRKP isolates in Turkey. Most of the isolates harboured blaOXA-48, blaVIM and blaSME genes; meanwhile, the rate of 20.4% for blaNDM is alarming.
