Hepatitis B, Hepatitis C and human immunodeficiency virus prevalences among first time blood donors in Istanbul, Turkey, 2004-2011
No full textObjective: This study aims to determine the yearly change rates of the HBsAg, anti-HCV and anti-HIV test results and their positivity rates obtained from the 68,393 donors who applied and donated blood for the first time at the Blood Center of the hospital. Materials and Methods: Using the ELISA method, screening tests were applied to the blood samples obtained from blood donors, and the HBsAg, anti-HCV and anti-HIV positivity rates were calculated at the end of year eight. However, HBsAg and anti-HCV positivities showed a decreased tendency of positivity in years. Results: A total of 68,393 donations were received within eight years. Seroprevalences for anti-HIV, HBsAg and anti-HCV tests were, respectively 0.01%, 1.54% and 0.38%. HBsAg and anti-HCV positivities showed a decreased tendency of positivity in years.

The risk factors of colistin methanesulfonate associated nephrotoxicity
No full textPurpose: The risk factors of colistin methanesulfonate (CMS) associated nephrotoxicity are important. Our study attempts look into the prevalence of CMS-associated nephrotoxicity in Intensive Care Units (ICUs), and related risk factors. Materials and Methods: The study was conducted between September 2010 and April 2012 on 55 patients who underwent CMS treatment. Nephrotoxicity risk was defined based on the Risk Injury Failure Loss End-stage kidney disease criteria. Results: Fifty-five patients included in the study. A total of 22 (40%) patients developed nephrotoxicity. The correlation was detected between nephrotoxicity and patients over 65 with a high Acute Physiologic Assessment and Chronic Health Evaluation (APACHE) II score. APACHE II score was revealed an independent risk factor for nephrotoxicity. Conclusion: Advanced age and a high APACHE II score are significant risk factors in the development of nephrotoxicity at ICUs following CMS use. Patient selection and close monitoring are critical when starting CMS treatment
Rectal colonization with multidrug-resistant gram-negative bacteria in patients with hematological malignancies: a prospective study
No full textObjectives To investigate the risk factors for rectal colonization with carbapenem-resistantEnterobacteriaceae(CRE) and extended-spectrum ss-lactamase-producingEnterobacteriaceae(ESBL-E) in hematological malignant patients with febrile neutropenia (FN); rate of rectal colonization and infection/colonization with CRE and ESBL-E; whether empirical treatment can be revised. Methods Adult patients receiving chemotherapy were included. Rectal swab cultures of patients were screened for CRE and ESBL-E using selective chromogenic agars. Results Fifty-seven FN episodes of 57 patients were studied. Rectal colonization rates were 40.4% (23/57) and 8.8% (5/57) for ESBL-E and CRE, respectively. ESBL-E bacteremia was diagnosed in 2 (8.6%) ESBL-E colonized patients, while CRE bacteremia was detected in 1 (20%) CRE colonized patient. Amikacin (100%) and carbapenem (93%) were the most effective antibiotics against gram-negative enteric bacteria. Beta-lactam usage within the last 3 months was a significant risk factor for ESBL-E colonization. Conclusions For the treatment of FN patients either colonized with ESBL-E or having significant risk factors for ESBL-E infection, aminoglycoside containing combinations may become an alternative to carbapenems due to their high sensitivity rates. When CRE colonized hematological cancer patients develop FN or if they are hemodynamically unstable, CRE covering empiric antibiotherapy should be preferred due to high mortality rates of CRE bacteremia

Delftia acidovorans: A rare pathogen in immunocompetent and immunocompromised patients
No full textDelftia acidovorans is an aerobic, nonfermenting Gram-negative bacillus. It is usually a nonpathogenic environmental organism and is rarely clinically significant. Although D acidovorans infection most commonly occurs in hospitalized or immunocompromised patients, there are also several reports documenting the infection in immunocompetent patients. The present article describes a B cell lymphoblastic leukemia patient with D acidovorans pneumonia who was successfully treated with antibiotic therapy. The present report indicates that unusual pathogens may be clinically significant in both immunocompromised and immunocompetent patients. D acidovorans is often resistant to aminoglycosides; therefore, rapid detection of this microorganism is important
Occupation-Related Injuries Among Healthcare Workers: Incidence, Risk Groups, and the Effect of Training
No full textBackground and objective Occupation-related injuries (ORIs) are undesirable and harmful situations among healthcare workers (HCWs) and may have serious consequences. In this study, we aimed to identify and analyze ORI incidences, risk groups, and the outcomes of a training program to prevent them. Materials and methods Between January 2011 and December 2019, HCWs who applied for infection prevention and control (IPC) due to ORIs (percutaneous needlestick and sharp-object injury or contact with blood or body fluids) were included in the study. Their characteristic features, vaccine histories, injury types, viral serologies, and administered prophylaxis were recorded. After 2014, a periodic ORI training program was started. We used joinpoint regression analysis to compare the ORI incidences before and after the education program. Results During the nine-year study period, 965 ORIs were registered. The mean age of HCWs was 39.3 +/- 8.4 years, and 67.9% of them were female. The total injury incidence for all professions was 34.1 (95% CI: 33.1-37.5) per 1,000 HCWs. The injury incidences were significantly higher in nurses compared to other HCWs (p<0.01). Most of the injuries occurred in the ward setting (37%). HCWs were injured most commonly while administering treatment (36.7%). The trend analysis for the incidence of injuries showed no significant change throughout the study period. The trend in personal protective equipment (PPE) use showed a significant increase (annual percentage change: 1.7, p<0.01). Conclusions The major finding of this study with respect to its implication on the healthcare system is that nurses are an important risk group for ORIs. Although the ORI incidence did not change during the study period, a significantly increased use of appropriate PPE following a systematic training program implementation was observed
Hospital acquired Clostridioides difficile infection and risk factors for severity in a university hospital: A prospective study
No full textBackground: Clostridioides difficile infection (CDI) is a well-known cause of health care-associated diarrhea. Data about CDI epidemiology of Turkey is limited. This study investigates CDI incidence, clinical characteristics, and factors associated with severe CDI in a tertiary care center university hospital. Methods: This is a case control study was conducted between 2012 and 2016. We included all patients, 18 years of age or more, with CDI diagnosis. For each patient diagnosed with CDI, information was collected concerning the severity of disease, treatment regimen, treatment response, disease recurrence, 30-day case fatality. Cases defined as severe hospital acquired CDI (HA-CDI) and controls defined as non-severe CDI patients. Results: We identified 100 cases of HA-CDI out of 111 patients. Total CDI incidence was 1.19/10,000 patient days. The incidence decreased 32.5% during the study period. We identified severe CDI in 24% of patients. Age and admission to intensive care unit were independent risk factors for severe CDI. Conclusion: This study reports a 5-year prospective epidemiology of CDI in a tertiary care center in Istanbul, Turkey. The findings of this study suggest that HA-CDI incidence and proportion of severe CDI is low compared to European and US literature. We believe that CDI is underreported, neglected but still an important health care associated infection in Turkey. (C) 2020 Association for Professionals in Infection Control and Epidemiology, Inc.
