Severe Fungal Infections

Severe fungal infection means invasive disease affecting blood, lungs, brain or deep tissue rather than a superficial skin rash. It is most common in people with major immune or hospital-related risk factors.

Nizoral

Ketoconazole

This treatment is utilized to mitigate severe systemic fungal conditions and designed to address hormone-related pathologies such as cushing's syndrome.

Key takeaways

  • Persistent fever despite antibiotics, lung deterioration, neurological change or deep-tissue destruction can raise concern in a high-risk patient.
  • Immune status, recent surgery, devices, imaging, cultures, antigen or molecular tests help identify the organism and site.
  • Antifungals are not interchangeable; species, resistance, organ function, interactions and tissue penetration determine treatment.

Catalogue matches are not treatment for suspected invasive fungal disease and should not delay emergency specialist care.

Who is at greatest risk?

Prolonged neutropenia, transplant treatment, intensive-care illness, major abdominal surgery, central lines, uncontrolled diabetes and high-dose immune suppression can increase risk. The likely fungus differs by exposure and immune defect.

Why must treatment be species-specific?

Different fungi respond to different drug classes, and delayed active therapy can be dangerous. Oral ketoconazole is not a routine treatment for invasive fungal infection because safer or more appropriate agents are generally selected by specialists. See antifungals.

When to seek urgent care

Seek emergency care for severe breathlessness, coughing blood, confusion, seizure, new weakness, black or rapidly dying tissue, or persistent fever with deterioration in an immunocompromised person.
