Rhinocerebral mucormycosis: premortem diagnosis and therapy
Abstract:
The diagnosis of rhinocerebral mucormycosis is most often made at autopsy. We report a series of nine patients in whom the diagnosis was established premortem. Six of the patients had underlying diabetes mellitus and three had acute leukemia. Facial or ocular pain was the complaint found in all patients, and frequently was the initial symptom. The diagnosis was established by examination and culture of infected tissue obtained by biopsy. In seven patients, identification of hyphal elements in smears of biopsy material allowed the immediate institution of amphotericin B therapy. Four of the seven patients treated with amphotericin B survived. All surviving patients had underlying diabetes mellitus and had undergone surgical debridement. Early diagnosis leading to immediate institution of appropriate therapy is most important for survival of patients with mucormycosis.
Insights
Early diagnosis of rhinocerebral mucormycosis is crucial for survival. Prompt identification via biopsy and treatment with amphotericin B, especially in diabetic patients, significantly improves outcomes.
Area of Science:
- Medical Mycology
- Infectious Diseases
- Critical Care Medicine
Background:
- Rhinocerebral mucormycosis is a rare but aggressive fungal infection.
- Diagnosis is often delayed, leading to high mortality rates.
- Underlying conditions like diabetes mellitus and acute leukemia increase susceptibility.
Purpose of the Study:
- To highlight the importance of premortem diagnosis of rhinocerebral mucormycosis.
- To evaluate the effectiveness of early diagnostic methods and treatment.
- To identify factors associated with patient survival.
Main Methods:
- Retrospective case series of nine patients with confirmed rhinocerebral mucormycosis.
- Diagnosis established through clinical examination, biopsy, and fungal culture.
- Treatment included amphotericin B and surgical debridement.
Main Results:
- Facial or ocular pain was the presenting symptom in all patients.
- Premortem diagnosis was achieved in all nine cases.
- Seven patients received amphotericin B, with four survivors.
- All survivors had diabetes mellitus and underwent surgical debridement.
Conclusions:
- Premortem diagnosis of rhinocerebral mucormycosis is feasible and essential.
- Early identification via biopsy and prompt initiation of amphotericin B therapy improve survival.
- Surgical debridement and management of underlying conditions are critical for favorable outcomes.
