OBJECTIVE: The aim of this retrospective study was to estimate the prevalence of healthcare-associated infections (HAI), microbiological data including resistance patterns and impact of HAI on patients' survival. METHODS: Two-centre study on 172 patients was performed. Medical records of patients hospitalized in the two COVID-19 intensive care units (ICU) localized in Bydgoszcz between 1 October 2020 and 30 March 2021 were analysed retrospectively. Data collection included demographics, microbiological, clinical variables, and patient outcome. All infections were defined according to the HAI-Net ICU protocol of the European Centre for Disease Prevention and Control (ECDC). Detailed data concerning bloodstream infection (BSI), pneumonia (PN) and urinary tract infection (UTI) were collected. RESULTS: In 97 patients (56.4%), 138 HAI cases were identified. Patients with HAI statistically more often had been administered antimicrobial therapy prior to the admission to ICU (59.8% vs. 34.7%, p < 0.05), and needed catecholamines during hospitalization (93.8% vs. 70.7%, p < 0.001). The risk of HAI increased by 50% if antimicrobial therapy had been applied before the admission to ICU, and was three times higher if during the hospitalization in ICU catecholamines infusion was needed. Mortality was higher in patients diagnosed with HAI (72.2% vs. 65.3%) but the difference was not statistically significant (p = 0.34). CONCLUSIONS: Further investigation of co-infections in critically ill patients with COVID-19 is required in order to identify HAI risk factors, define the role of empiric antimicrobial therapy and proper prevention strategies.

We aimed to describe the clinical presentation, treatment, outcome and report on factors associated with mortality over a 90-day period in Clostridioides difficile infection (CDI). Descriptive, univariate, and multivariate regression analyses were performed on data collected in a retrospective case-control study conducted in nine hospitals from seven European countries. A total of 624 patients were included, of which 415 were deceased (cases) and 209 were still alive 90 days after a CDI diagnosis (controls). The most common antibiotics used previously in both groups were β-lactams; previous exposure to fluoroquinolones was significantly (p = 0.0004) greater in deceased patients. Multivariate logistic regression showed that the factors independently related with death during CDI were older age, inadequate CDI therapy, cachexia, malignancy, Charlson Index, long-term care, elevated white blood cell count (WBC), C-reactive protein (CRP), bacteraemia, complications, and cognitive impairment. In addition, older age, higher levels of WBC, neutrophil, CRP or creatinine, the presence of malignancy, cognitive impairment, and complications were strongly correlated with shortening the time from CDI diagnosis to death. CDI prevention should be primarily focused on hospitalised elderly people receiving antibiotics. WBC, neutrophil count, CRP, creatinine, albumin and lactate levels should be tested in every hospitalised patient treated for CDI to assess the risk of a fatal outcome.

Mucormycosis is a rare fungal infection in immunocompetent patients, whereas in immunocompromised, it may be systemic and disseminated infection associated with high mortality. Mucormycosis is one of the most rapidly progressing and fulminant forms of fungal infections; Mucor circinelloides is rarely isolated species, also from immunocompromised patients. The reported case of mucormycosis after a traffic accident indicates that it may be the result of a contamination of wound by M. circinelloides coming from the environment. The fungal strain was identified by phenotypic methods and confirmed by molecular methods. Etest method was used for susceptibility testing of the fungal strain. No mycotoxins were detected in the analyzed sample. The infection was successfully treated with amphotericin B, but amputation of the lower limb was necessary.

According to studies, latent Toxoplasma gondii infection may affect several functions of the human brain. Here we search for the association between latent toxoplasmosis and cognitive performance. We tested 70 individuals for latent T. gondii infection. There were 26 Toxoplasma-infected subjects and 44 Toxoplasma-free subjects. Within these two groups we assessed cognitive performance using a set of standardized, widely recognized neuropsychological tests: Trail Making Test, Stroop Test, Verbal Fluency Test, Digit Span Test and N-back test. The relationship between chronic toxoplasmosis and cognitive performance was assessed, with adjustment for age and sex. Patients with latent toxoplasmosis performed worse on one neuropsychological test, N-back Test – percentage of correct answers (β −8.08; 95%CI −15.64 to −0.53; p<0.05) compared to seronegative patients. However, after adjustment for age and sex, no statistically significant associations between latent toxoplasmosis and the scores on any cognitive tests were noticed. As statistically significant relationship was not observed, this study does not confirm that chronic latent T. gondii infection affects cognition.
