Objective To retrospectively analyze the clinical characteristics, treatment and prognosis of the elderly patients with COVID-19 combined with fungal infection, and to explore the risk factors of COVID-19 combined with fungal infection. Methods The clinical data of the patients with COVID-19 who were hospitalized in the Geriatric Hospital of Nanjing Medical University from December 13, 2022 to January 31, 2023 were collected. The patients with positive fungal results in sputum culture, alveolar lavage fluid culture, blood culture, urine culture, stool culture and gastric juice culture were screened. The data of gender, age, Charlson comorbidity index (CCI), clinical symptoms, complete blood count, liver and kidney function, serum albumin, fasting blood glucose (FPG), glycosylated hemoglobin (HbA1c), high-sensitivity C-reactive protein (hs-CRP), procalcitonin, arterial partial pressure of oxygen (PaO2), arterial partial pressure of carbon dioxide (PaCO2), oxygenation index (PaO2/FiO2), D-dimer, carcinoembryonic antigen (CEA), thyroid function, interleukin-6 (IL-6), lymphocyte subgroup analysis, pathogenic culture results, days from fungal positive to admission, treatment and prognosis were analyzed. Results A total of 169 patients with COVID-19 were collected, including 21 patients combined with fungal infection. Among the patients with COVID-19 combined with fungal infection, the median length of hospital stay was 20.0 (15.0, 28.5) d, male constituted the majority of 81.0%, the median age was 89.0 (81.5, 92.5) years, and CCI was 6 (5, 9); The main clinical classification of COVID-19 among the patients was critical type (52.4%); The main fungi were Candida albicans and Candida glabrata; Six patients (28.6%) ultimately died. 169 patients with COVID-19 were divided into fungal infection group and non-fungal infection group. There were significant differences in age, hospitalization days, clinical classification, procalcitonin, serum albumin, blood urea nitrogen (BUN), FPG, D-dimer, CEA, PaO2/FiO2, and the highest respiratory support mode between the two groups (all P<0.05). Further Logistic regression analysis showed that procalcitonin (OR=1.411) and invasive ventilation as the highest respiratory support mode (OR=27.482) were the independent influencing factors for COVID-19 combined with fungal infection. Conclusions Procalcitonin and invasive ventilation as the highest respiratory support mode may be independent risk factors for COVID-19 combined with fungal infection. Early screening and early treatment should be carried out for the high-risk groups of COVID-19 combined with fungal infection, so as to protect the patients.
