  • a Invasive pulmonary aspergillosis developed in one patient, and Candida parapsilosis fungemia developed in another patient in the study.

  • b Filamentous fungal pneumonia (species not identified).

  • c Invasive pulmonary aspergillosis.

  • d Severe fluconazole-resistant esophageal candidiasis with resolution of odynophagia and dysphagia and partial reduction of mucosal plaques.

  • e One patient had relapsed cryptococcal meningitis after 3 weeks of L-AMB and 4 days of maintenance fluconazole. Among all patients with a successful response, two patients had candidemia caused by C. albicans and C. parapsilosis, which completely resolved, and two patients with invasive pulmonary aspergillosis had stable disease.

  • f One patient died with culture- and biopsy-proven acute pulmonary and hepatic disseminated candidiasis and refractory leukemia after 2 days of L-AMB following withdrawal of all supportive care.

  • g NA, not applicable.
