    Solid organ transplantation (SOT) is a treatment method that improves quality of life and survival of patients with end-stage organ failure. Immunosuppressive treatments given to these patients may predispose to the development of invasive fungal infections (IFI). The incidence of IFI in SOT recipients, which is between 5% and 42%, depends on the organ to be transplanted. Although Candida spp., followed by Aspergillus spp. are the most common microorganisms, among fungal pathogens, this situation varies according to transplant type. The mortality rate associated with these IFI can be high. Therefore, antifungal prophylaxis may be necessary for SOT recipients. Many transplantation centers employ antifungal strategies according to their own experience because of the lack of randomized controlled studies. If the antifungal prophylaxis is given to all patients, antimicrobial resistance and drug-drug interactions may occur. Therefore, it is important to identify patients at a high risk of developing IFI. In this paper, epidemiology, risk factors, literature data and antifungal prophylaxis associated with IFI in liver, kidney, small intestine, pancreas, heart, and lung transplant recipients are reviewed.

    Candidemia may present as severe and life-threatening infections and is associated with a high mortality rate. This study aimed to evaluate the risk factors associated with 30-day mortality in patients with candidemia. A multi-center prospective observational study was conducted in seven university hospitals in six provinces in the western part of Turkey. Patient data were collected with a structured form between January 2018 and April 2019. In total, 425 episodes of candidemia were observed during the study period. Two hundred forty-one patients died within 30 days, and the 30-day crude mortality rate was 56.7%. Multivariable analysis found that SOFA score (OR: 1.28, CI: 1.154-1.420, p < 0.001), parenteral nutrition (OR: 3.9, CI: 1.752-8.810, p = 0.001), previous antibacterial treatment (OR: 9.32, CI: 1.634-53.744,p = 0.012), newly developed renal failure after candidemia (OR: 2.7, CI: 1.079-6.761, p=0.034), and newly developed thrombocytopenia after candidemia (OR: 2.6, CI: 1. 057-6.439, p =0.038) were significantly associated with 30-day mortality. Central venous catheter removal was the only factor protective against mortality (OR: 0.34, CI:0.147-0.768, p = 0.010) in multivariable analysis. Candidemia mortality is high in patients with high SOFA scores, those receiving TPN therapy, and those who previously received antibacterial therapy. Renal failure and thrombocytopenia developing after candidemia should be followed carefully in patients. Antifungal therapy and removing the central venous catheter are essential in the management of candidemia.

    OBJECTIVE: As the pandem-ic continues, different vaccine protocols have been implemented to maintain the protection of vaccines and to provide protection against new variants. The aim of this study was to as-sess hospitalized patients' vaccination status and document the efficacy of boosters.PATIENTS AND METHODS: The patients that were hospitalized due to COVID-19 were enrolled from 28 hospitals in Turkey for five months from September 2021. 5,331 confirmed COVID-19 pa-tients from collaborating centers were random-ly enrolled to understand/estimate the distri-bution of vaccination status in hospitalized pa-tients and to compare the efficacy of vaccina-tion/booster protocols.RESULTS: 2,779 men and 2,552 women of which 2,408 (45.2%) were admitted to Intensive Care Units participated in this study. It was found that the highest risk reduction for all age groups was found in groups that received 4 doses. Four doses of vaccination for every 3.7 people under 50 years of age, for every 5.7 people in the 50-64 age group, and for every 4.3 people over 65 years of age will prevent 1 patient from being admitted to intensive care. Regardless of the type of vaccine, it was found that the risk of ICU hospitalization decreased in those who were vaccinated compared to those who were not vaccinated. Regardless of the type of vaccine, the ICU risk was found to decrease 1.25-fold in those who received 1 or 2 doses of vaccine, 1.18-fold in those who received 3 dos-es, and 3.26-fold in those who received 4 doses.CONCLUSIONS: The results suggested that the addition of a fourth dose is more effective in preventing intensive unit care even in disad-vantaged.

    Objective Vaccination is the most efficient way to control the coronavirus disease 2019 (COVID-19) pandemic, but vaccination rates remain below the target level in most countries. This multicenter study aimed to evaluate the vaccination status of hospitalized patients and compare two different booster vaccine protocols. Setting Inoculation in Turkey began in mid-January 2021. Sinovac was the only available vaccine until April 2021, when BioNTech was added. At the beginning of July 2021, the government offered a third booster dose to healthcare workers and people aged > 50 years who had received the two doses of Sinovac. Of the participants who received a booster, most chose BioNTech as the third dose. Methods We collected data from 25 hospitals in 16 cities. Patients hospitalized between August 1 and 10, 2021, were included and categorized into eight groups according to their vaccination status. Results We identified 1401 patients, of which 529 (37.7%) were admitted to intensive care units. Nearly half (47.8%) of the patients were not vaccinated, and those with two doses of Sinovac formed the second largest group (32.9%). Hospitalizations were lower in the group which received 2 doses of Sinovac and a booster dose of BioNTech than in the group which received 3 doses of Sinovac. Conclusion Effective vaccinations decreased COVID-19-related hospitalizations. The efficacy after two doses of Sinovac may decrease over time; however, it may be enhanced by adding a booster dose. Moreover, unvaccinated patients may be persuaded to undergo vaccination.
