Abstract

Background

The COVID-19 pandemic and the emergence of have changed the epidemiological landscape of candidaemia worldwide.

Aim

We compared the epidemiological trends of candidaemia in a Greek tertiary academic hospital before (2009–2018) and during the early COVID-19 (2020–2021) and late COVID-19/early post-pandemic (2022–2023) era.

Methods

Incidence rates, species distribution, antifungal susceptibility profile and antifungal consumption were recorded, and one-way ANOVA or Fisher’s exact test performed. Species were identified by MALDI-ToF MS, and in vitro susceptibility determined with CLSI M27-Ed4 for and the EUCAST-E.DEF 7.3.2 for other spp.

Results

In total, 370 candidaemia episodes were recorded during the COVID-19 pandemic. Infection incidence (2.0 episodes/10,000 hospital bed days before, 3.9 during the early and 5.1 during the late COVID-19 era, p < 0.0001), (0%, 9% and 33%, p < 0.0001) and fluconazole-resistant species complex (SC) (20%, 24% and 33%, p = 0.06) infections increased over time, with the latter not associated with increase in fluconazole/voriconazole consumption. A significant increase over time was observed in fluconazole-resistant isolates regardless of species (8%, 17% and 41%, p < 0.0001). Resistance to amphotericin B or echinocandins was not recorded, with the exception of a single pan-echinocandin-resistant strain.

Conclusion

Candidaemia incidence nearly tripled during the COVID-19 era, with among the major causative agents and increasing fluconazole resistance in SC. Almost half of isolates were fluconazole-resistant, underscoring the need for increased awareness and strict implementation of infection control measures.
