    Objectives: The clinical features and treatment approaches, outcomes, and mortality predictors of COVID-19 in solid-organ transplant recipients have not been well defined. This study investigated the clinical features of COVID-19 infection in solid-organ transplant recipients at our center in Turkey. Materials and Methods: Our study included 23 solid-organ transplant recipients and 336 nontransplant individuals (143 previously healthy and 193 patients with at least 1 comorbidity) who were hospitalized due to COVID-19 disease in our hospital between March 2020 and January 2021. Demographic, clinical, and laboratory data of patients were compared. We used SPSS version 20.0 for statistical analysis. All groups were compared using chi-square and Mann-Whitney U tests. P <.05 was considered statistically significant. Results: Mean age of solid-organ transplant recipients was 49.8 +/- 13.7 years (78.3% men, 21.7% women). Among the 23 recipients, 17 (73.9%) were kidney and 6 (26.1%) were liver transplant recipients. Among nontransplant individuals, 88.7% (n = 298) had mild/moderate disease and 11.3% (n = 38) had severe disease. Among transplant recipients, 78.3% (n = 18) had mild/moderate disease and 21.7% (n = 5) had severe disease (P =.224). Transplant recipients had greater requirements for nasal oxygen (P =.005) and noninvasive mechanical ventilation (P =.003) and had longer length of intensive care unit stay (P =.030) than nontransplant individuals. No difference was found between the 2 groups in terms of mortality (P =.439). However, a subgroup analysis showed increased mortality in transplant recipients versus previously healthy patients with COVID-19 (P <.05). Secondary infections were major causes of mortality in transplant recipients. Conclusions: COVID-19 infection resulted in higher mortality in solid- organ transplant recipients versus that shown in healthy patients. More attention on secondary infections is needed in transplant recipients to reduce mortality.

    Cross-Sectional Analysis Of Tobacco Addiction In Hospitalized COVID-19 Patients
    (2022) Darilmaz Yuce, Gulbahar; Torun, Serife; Hekimoglu, Koray; Tuna, Derin; Sozbilici, Betul Rana; Cetin, Hikmet Oguz; Narlioglu, Mehmet Emin; Balli, Murat; Ozyesil, Ahmet Suheyl; Yavuz Colak, Meric; Ulubay, Gaye; Akcay, Muserref Sule; https://orcid.org/0000-0002-0805-0841; 36164949; AAD-9097-2021
    Introduction: The COVID-19 pandemic has become an important health issue with consequences for special populations since 2019. Tobacco use is an important public health issue and tobacco users are a risk group for lung infections.Materials and Methods: The aim of this study is to obtain information about disease prevalence and severity, laboratory parameters, and changes in radio-logical findings between smokers and non-smokers who were hospitalized, followed up, and treated for COVID-19, and to find answers to critical questi-ons regarding the response to antiviral and supportive therapy. Two hundred eighty-six patients who were hospitalized and treated between March 2020-February 2021 in the COVID-19 Isolation Ward of Baskent University Hospital were included in the study. The patients were grouped as current smokers, non-smokers, and ex-smokers. The groups were compared in terms of symptoms, laboratory findings, radiological findings, and treatment respon-se.Results: The median age of the patients included in the study was 59 (IQR= 32). Of the patients, 40.6% were female and 59.4% were male. In our study, we discovered that there were fewer female smokers (p< 0.001). When the current smokers (n= 56), non-smokers (n= 159), and ex-smokers (n= 71) were compared based on their findings, it was found that dyspnea was more common in current smokers (p= 0.009). Lung involvement was found to be more common (p= 0.002) and multifocal in the current smokers group (p= 0.038). The levels of oxygen saturation at the times of admission and discharge were lower in current smokers (p= 0.002 and p= 0.038). The need for nasal oxygen and noninvasive mechanical ventilation was also found to be higher in current smokers (p= 0.008 and p= 0.039). Systemic steroid requirement was higher in current smokers (p= 0.013). There was no statistically significant differen-ce in terms of mortality between current smokers, ex-smokers, and non-smokers (p= 0.662).Conclusion: The analysis of the findings of the patients hospitalized in the COVID-19 isolation ward indicated that COVID-19 leads to a more serious course in patients with a history of smoking.
