Background: Emerging carbapenem-resistant Klebsiella pneumoniae (K. pneumoniae) (CRKP) bacteremias are presenting significant public health risks due to limited treatment options and increased mortality. K. pneumoniae isolates exhibit carbapenem resistance rates that vary from 25% to 50% throughout the European continent, including our country. Aims: To assess the characteristics of CRKP bacteremia, a condition that has recently demonstrated an increasing prevalence in our center. We sought to ascertain the resistance rates of isolated strains to antibiotics other than carbapenems, identify the responsible carbapenemase genes, evaluate the efficacy of antibiotics, determine mortality rates, explore clonality among strains, and investigate the influence of the COVID-19 pandemic on all these factors. Study Design: Retrospective observational study. Methods: This study included patients aged 18 and older who had experienced meropenem-resistant K. pneumoniae bacteremia. Meropenem resistance was confirmed by employing the Kirby-Bauer disk diffusion method. Meropenem minimum inhibitory concentration (MIC) levels were determined using the gradient test, while colistin MIC levels were ascertained using the disk elution technique. Carbapenemase genes were evaluated via colony polymerase chain reaction (PCR), and clonality analysis was performed using the arbitrarily primed PCR technique. Results: The study comprised 230 patients, with a mean age of 63.1 ± 15.9 years, of whom 58.7% were male. Oxacillinase-48 (OXA-48) was detected in 74.8% of the patients, New Delhi metallo-beta-lactamase (NDM) in 12.6%, OXA-48 + NDM in 7.8%, and KPC in 4.8%. The 14-day and 30-day mortality rates were 57% and 69.6%, respectively. Multivariate analysis of the 30-day mortality revealed several crucial factors, including bacteremia development in the intensive care unit, the occurrence of bacteremia during the COVID-19 pandemic, polymicrobial bacteremia, the use of indwelling intravenous catheters, a platelet count of ≤ 140,000/µl, procalcitonin levels of ≥ 6 µg/l, and a Charlson comorbidity score ≥ 3. Notably, the OXA-48 and KPC genes were upregulated significantly during the COVID-19 pandemic, while the NDM gene groups were downregulated. Additionally, both 14-day and 30-day mortality rates increased significantly. Conclusion: In this study, the most prevalent carbapenemase gene was OXA-48; however, there has been a recent increase in KPC genes. No dominant epidemic strain was identified through clonality analysis. The clustering rate was 68% before the pandemic, increasing to 85.7% during the pandemic. The significance of infection control measures is underscored by the rise in both clustering and mortality rates during the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

This consensus report includes expert opinions and recommendations regarding the screening, and if necessary, the follow-up, prophylaxis, and treatment of hepatitis B before the treatment in patients who will undergo immunosuppressive therapy due to an emergency risk of hepatitis B reactivation. To increase awareness regarding the risk of hepatitis B reactivation in immunosuppressive patients, academicians from several university health research and training centers across Turkey came together and discussed the importance of the subject, current status, and issues in accordance with the current literature data and presented solutions.

Objective: We aimed to evaluate the diagnostic and therapeutic approaches of invasive mold infections in febrile neutropenic patients. Methods: This retrospective and single-center study includes patients with hematologic malignancy and invasive mold infections. Predictors for 30-day and 1-year mortality were determined. Results: A total of 87 patients were recorded. Of whom, 48 (55.2%) were male and the mean age was 44.56 ± 15.83. Twenty patients were in the empirical therapy group and 67 were in the preemptive group. Galactomannan positivity rate was found 24.1% (n = 21). The causative agents were detected in 16 patients. In the initial treatment, liposomal amphotericin B (n = 53), voriconazole (n = 27), caspofungin (n = 5), and posaconazole (n = 1) were used. The 30-day mortality rate was 26.4%, while the 1-year mortality rate was 44.8%. The 30-day (45.0% vs. 20.9%, P = .03) and 1-year (65% vs. 38.8%, P = .04) mortality rates were significantly higher in empirical treatment group than in preemptive treatment group. In multivariate analysis, presence of blasts in peripheral blood (P = .04, 95% CI = 1.01-9.38, odds ratio = 3.07) was determined as an independent risk factor for 30-day mortality. No independent risk factor was found for 1-year mortality. Conclusion: As a result, despite the early initiation of empirical treatment, preemptive therapy approach was as effective as empirical approach in the management of invasive mold infections. Therefore, invasive and noninvasive diagnostic methods should be used more frequently to decrease overtreatment. In conclusion, current interdisciplinary approaches are crucial for evidence-based early diagnosis in immunocompromised patients with hematologic malignancies. [ABSTRACT FROM AUTHOR]

The article focuses on liver enzyme changes in hospitalized COVID-19 patients, particularly their frequency and relation to poor prognosis or mortality. It study analyzes data from COVID-19 patients admitted between March and July 2020, categorizing them into ICU and non-ICU groups and assessing liver enzyme patterns and their impact on outcomes.

Background: Human immunodeficiency virus (HIV) is still a challenge for children. About 15 to 45% of the HIV positive pregnant women can transmit the virus to their children during pregnancy, delivery and/or breastfeeding. The risk of transmission can be decreased my several measures. Aims: To identify factors associated with HIV infection in children born to HIV-infected mothers. Study Design: A multi-center retrospective cohort study. Methods: A ten-year retrospective cohort study in five dedicated HIV centers was conducted. The 325 women in our cohort were between the ages of 18 and 45. During the study period, 44 (13.5%) of these women gave birth and 51 babies were born. Of the 51 infants, 7 (13.7%) were HIV/AIDS positive. Results: Among the factors studied, breastfeeding, having a HIV-positive sibling and being on antiretroviral treatment during pregnancy and detectable HIV-RNA during delivery were found statistically significant. A multivariable logistic regression analysis showed that being on antiretroviral treatment during pregnancy is the most important predictor of mother-to-child transmission. Conclusion: Mother-to-child transmission appears to be an important route of HIV transmission in Turkey. Lack of antiretroviral treatment during pregnancy appears to be a key factor in transmission.
