Revision as of 19:20, 14 August 2019
Microbiology
- Dimorphic fungus with four phylogenetic lineages
- Disease is caused by P. brasiliensis and P. lutzii (newly discovered)
- Mariner's wheel of budding conidia
Epidemiology
- South and Central America, with Brazil being the largest endemic country
- Has been isolated from the feces of bats (Artibeus lituratus) and from internal organs of the nine-banded armadillo
Clinical Presentation
- Usually self-limited pulmonary infection
- Can cause acute/subacute pulmonary infection in children, adolescents, and immunocompromised individuals
- Fever, weight loss, lymphadenopathy, and hepatosplenomegaly
- Half have skin and mucosal lesions
- Can cause chronic disease in adults
- Pulmonary infiltrates on CXR
- Adrenal lesions with insufficiency are common
- However, may remain latent following infection, and reactivate later as pulmonary or disseminated disease
Diagnosis
- Serology
- Antibodies
- Antigen
Management
- Itraconazole 200 to 400 mg/day for 9 to 12 months
- If severe, consider amphotericin 1mg/kg/day
- ?Septra
