Invasive fungal infections
and COVID-19

An emerging association

Invasive aspergillosis and mucormycosis represent a serious additional threat to COVID-19 patients who develop ARDS or are admitted to the ICU.1–5 Cases of COVID-19-associated pulmonary aspergillosis (CAPA) and COVID-19-associated mucormycosis (CAM) are increasingly being reported,6 with an overall prevalence among ICU patients of 9.3%7 and 1.6%8, respectively.

How many critically ill patients develop invasive aspergillosis in the ICU?​​​​​​​a

a. Cases of invasive aspergillosis (mainly pulmonary) reported among ICU patients in different prospective and retrospective studies. 

When to suspect

Some potential risk factors predisposing COVID-19 patients to secondary invasive fungal infections have been identified:1,7,8,15–18

  • ​​​​​​​​​​​​Use of corticosteroids
  • Widespread use of broad-spectrum antibiotics in the ICU
  • Immune dysregulation associated with COVID-19​​​
  • Presence of comorbidities, particularly those causing structural lung damage
  • Trauma, diabetes mellitus, haemopoietic malignancy, prolonged neutropenia, patients undergoing HSCT/SOT

Risk factors for invasive fungal infections in the ICU

Considerations when treating

Effective management of CAPA and CAM requires prompt diagnosis, treatment of underlying diseases, and aggressive medical intervention.1,19-21 However, clinical and radiological signs of CAPA and CAM can overlap – and there have been reports of simultaneous mixed superinfection – which may complicate the diagnosis.5,6,22

While there are several approved treatments for invasive aspergillosis and mucormycosis, an individualised assessment should be considered for every patient, taking into account differences in coverage, tolerability, drug interaction profile, and PK.23-26

CRESEMBA® (isavuconazole) is recommended by the ECMM for the treatment of CAPA and CAM27,28

CRESEMBA® is indicated in adults for the treatment of:23
  • • Invasive aspergillosis
  • • Mucormycosis in patients for whom amphotericin B is inappropriate
Consideration should be given to official guidance on the appropriate use of antifungal agents.

Key facts

  • Cases of CAPA and CAM are increasingly being reported:6 overall prevalence among ICU patients is 9.3%7 and 1.6%8, respectively
  • Mortality rate of CAPA and CAM in ICU patients with COVID-19 is ~50%7,8,29,30  
  • Effective management of CAPA and CAM requires prompt diagnosis and treatment1,19-21

Why choose CRESEMBA® (isavuconazole)?

  • An effective, guidelines-endorsed antifungal therapy21,23,27,28,31,32
  • In the SECURE registration trial, both survival and overall response rates were non-inferior to voriconazole33
  • Better tolerated than voriconazole, with fewer drug-related AEs (42% [n=109] vs 60% [n=155], p<0.001) and drug-related events leading to discontinuation (8% [n=21] vs 14% [n=35])33
  • Fewer drug–drug interactions than other azoles23,34
  • Simple and reliable dosing with a linear PK profile (up to 600 mg per day), unlike other azoles23,35,36
  • May be used in patients with renal impairment or mild-to-moderate hepatic impairment without dose adjustments23,a

CRESEMBA® can offer the flexibility you need, so that you can focus on your patient’s underlying condition23,33,34,37
