Severe illness from COVID-19 increases susceptibility to fungal infections

Immunosuppression triggered by COVID-19 concomitant with its therapy via corticosteroids and comorbidities of the patients make fungal infections more susceptible.

According to a trial, severe COVID-19 disease is linked to higher levels of the tumour necrosis factor-alpha (TNF-α), interleukin (IL)-1, IL-6, and pro-inflammatory cytokines as well as reduced expression of CD4-interferon-gamma, CD8 and CD4 T cells, all of which raises vulnerability to fungal infections. Researchers aimed to investigate the progression of fungal infections linked to respiratory illnesses brought on by COVID-19.

Considering the significance of the coronavirus infection in connection to co-infections caused by various fungal microorganisms, the features of SARS-CoV-2 and the primary fungal species that are impacting people receiving treatment for severe COVID-19 were identified. Eighty articles from the scientific literature were chosen, with the majority of subjects with severe COVID-19 and concomitant conditions like obesity, oncological disorders, severe liver disease, renal illness, hypertension, and diabetes.

The cases reported by researchers in their series, which demonstrate the overlap of fungal co-infection through compromised immune status brought on by the dysregulation of the microbiota, utilization of therapeutic drugs, patient age, and the severity of the severe inflammation due to COVID-19 are represented by these data rather than the total number of records of the disease in the world.

Fungal infections are more susceptible due to immunosuppression elicited by SARS-CoV-2 infection, its treatment with corticosteroid therapy, and the comorbidities of the people. As a result, they interfere with the COVID-19 treatment and course of the case, making it crucial to recognize secondary infections for treatment and reconstruct the clinical picture as accurately as possible.
