Rhino-orbital-cerebral mucormycosis with CNS involvement: salvage protocol when first-line therapy fails to achieve stable or partial response
Clinical Scenario
This protocol applies to patients with rhino-orbital-cerebral mucormycosis in whom central nervous system (brain) involvement has been established, and who have not achieved the required treatment response on first-line management.
Why This Protocol Is Triggered
First-line management combines early complete surgical debridement — repeated as required — with immediate systemic antifungal therapy. The expected outcome at response assessment is at least stable disease or partial response on imaging. When that threshold is not reached, escalation to salvage therapy is indicated.
Salvage Approach
The strategy at this stage centres on switching to a different antifungal class as salvage therapy. The full protocol specifies which agents are recommended, the circumstances governing their use, and what further escalation options exist for progressive disease.
Treatment Goal
Complete resolution of the initially indicative mucormycosis findings on imaging.
References
- In CNS involvement, animal models and the above observations support use of liposomal amphotericin B at 10 mg/kg per day.
- Isavuconazole is strongly supported as salvage treatment.
- Posaconazole delayed release tablets or infusions are strongly supported for salvage treatment, and when available should be preferred over posaconazole oral suspension, which in turn is marginally supported for salvage treatment.
- In cases of primary treatment failure with isavuconazole or posaconazole, the guideline group supports recommendations for all three lipid-based amphotericin B formulations with strong to moderate strength.
- In case of extensive disease, rapid progression, or poor general condition, the addition of isavuconazole or posaconazole can be considered.
- Treatment should be continued until resolution of initially indicative findings on imaging and reconstitution of host immune system.
