Abstract

Since December 2019, coronavirus disease 2019 (COVID-19), which is caused by SARS-CoV-2, has spread locally in Wuhan, China, and later on, a worldwide outbreak occurred. Invasive fungal infections can cause complications in critically ill immunocompromised patients of COVID-19, especially those admitted to intensive care units and who required mechanical ventilation. have been the most common pathogenic species, followed by other spp. Mannan is a major component of the cell wall and can be detected by the enzyme-linked immunosorbent assay (ELISA) in blood and other fluids. Invasive pulmonary aspergillosis is considered a life-threatening infection, especially among immunocompromised patients. COVID-19-associated pulmonary aspergillosis has emerged as an important complication among patients in the intensive care units. Galactomannan (GM) is a major cell-wall component of spp. and can be found in body fluids. Blood GM can be detected by the enzyme immunoassay. The aim of the current study is to assess the frequency of aspergillosis and candidiasis among COVID-19 patients in some hospitals in Baghdad by using GM and mannan biomarkers. During the period from February 2020 to May 2021, 175 COVID-19 blood samples of patients were collected and a sandwich ELISA test was performed to detect GM Ag of spp. and mannan Ag of spp. Regarding C-reactive protein (CRP), significant differences were seen among /COVID-19 patients ( = 0.029). Regarding sex and age group, the results indicated that of a total of 175 adult patients with positive COVID-19, more than half of the patients were males. Regarding the distribution of mannan Ag and GM Ag in COVID-19 patients, it was seen that out of the 175 patients, 167 (95.43%) mannan Ag were negative and only 8 (4.57%) were positive, and 170 (79.14%) GM Ag were negative and only 5 (2.86%) were positive. It was also seen that 2 patients (1.14%) who had both mannan and GM were positive and 173 (98.6%) were negative. No statistically significant difference was seen in candidiasis and aspergillosis among patients with COVID-19 regarding age group, sex, underlying chronic diseases (hypertension and diabetes mellitus), and biochemical tests. COVID-19 infections increased with age and were seen more in males than in females. The percentage of infection with and spp. among COVID-19 patients was not significant, and this may come from the random collection of samples from patients with different stages of illness. A significant correlation was found between GM Ag in COVID-19 patients and the CRP test.
