Management of extrapulmonary aspergillosis
- The recommended treatment for central nervous system aspergilllosis is voriconazole; lipid formulations of AmB should be used only in patients who are intolerant or refractory to voriconazole.
- Aspergillus endophthalmitis should be treated with systemic oral or intravenous voriconazole plus intravitreal voriconazole or intravitreal AmB deoxycholate.
- Invasive Aspergillus fungal sinusitis should be treated with both surgery and either systemic voriconazole or a lipid formulation of AmB.
- Aspergillus endocarditis should be treated with early surgical intervention and antifungal therapy.
- Aspergillus osteomyelitis and arthritis should be treated with voriconazole and, where feasible, surgery.
- Patients with cutaneous aspergillosis should be evaluated for a primary focus of infection and treated with voriconazole. If aspergillosis is in burns or massive soft tissue wounds, surgical debridement is also recommended.
- Aspergillus peritonitis should be treated with prompt peritoneal dialysis catheter removal and systemic antifungal therapy with voriconazole.
- Esophageal, gastrointestinal, and hepatic aspergillosis should be treated with voriconazole and surgical consultation.
- Noninvasive Aspergilllus otititis externa can be treated through mechanical cleansing of the external auditory canal followed by topical antifungals or boric acid. IA of the ear should be treated with a prolonged course of systemic voriconazole and surgery.
- Aspergillus keratitis should be treated with topical natamycin 5% ophthalmic suspension or topical voriconazole.
- For non-transplant patients, Aspergillus bronchitis should be treated with oral itraconazole or voriconazole with TDM.
Prophylaxis of invasive aspergillosis
- Patients who are at high risk for IA should undergo prophylaxis with posaconazole, voriconazole, and/or micafungin during prolonged neutropenia.
- For lung transplant patients, antifungal prophylaxis should include either a systemic triazole or an inhaled AmB product for 3 to 4 months after lung transplant.
- For non-lung solid organ transplant patients, prophylactic strategies should be based on the institutional epidemiology of infection and assessment of individual risk factors.
Management of breakthrough infection
- Breakthrough aspergillosis should be managed through an individualized approach that considers the rapidity and severity of infection as well as local epidemiology.
- Empiric antifungal therapy is recommended for high-risk patients with prolonged neutropenia who are febrile despite broad-spectrum antibiotic therapy.
Chronic and saprophytic syndromes of Aspergillus
- Chronic cavitary pulmonary aspergillosis (CCPA) can be diagnosed if it meets the following criteria: 3 months of chronic pulmonary symptoms, chronic illness, or progressive radiographic abnormalities with cavitation, pleural thickening, pericavitary infiltrates, and sometimes a fungal ball; Aspergillus IgG antibody elevated or other microbiological data; and no or minimal immunocompromise.
- Patients with CCPA without pulmonary symptoms, weight loss, or significant fatigue can be observed and followed up after 3 to 6 months.
- Patients with CCPA with either pulmonary or general symptoms or progressive loss of lung function or radiographic progression should be treated with antifungal therapy for at least 6 months.
- Asymptomatic patients with a single Aspergillus fungal ball of the lung (aspergilloma) should continue to be observed.
- Patients with aspergillomas who are symptomatic should have it resected.
Allergic syndromes of Aspergillus
- Symptomatic asthmatic patients with allergic bronchopulmonary aspergillosis should be treated with oral itraconazole therapy with TDM.
- Patients with allergic fungal rhinosinusitis caused by Aspergillus species should undergo polypectomy and sinus washout. The use of topical nasal steroids and oral antifungal therapy are also recommended.
