Brief Summary
All patients with pulmonary blastomycosis requiring mechanical ventilation will have their blood concentrations measured for the antifungal drugs, amphotericin-B and voriconazole; as well as an analysis of the susceptibility of their infecting species of blastomyces. This information will then be analyzed relative to their rate of clinical recovery from this serious fungal infection.

Outcome Measures
Primary Outcomes (1)
The concentration-time profile of antifungals during treatment relative to the level of susceptibility of the infecting organism
within the first month of therapy
Secondary Outcomes (3)
Clinical recovery - as assessed by time to fever defervescence; and white blood cell (WBC) count resolution
2 to 3 days
Clinical recovery - time to discontinuation of mechanical ventilation
less than 7 days
Clinical recovery - time to respiratory dysfunction resolution
less than 4 days
Study Arms (1)
Amphotericin-B and Voriconazole
OTHERTreatment with a 24 hour continuous infusion of amphotericin B deoxycholate at 1.0 mg/kg/day for a total dose of at least 1 g (i.e. \~ 14 days); and then the patient is stepped down to voriconazole 6 mg/kg i.v. q12h for 2 doses, then 4 mg/kg q12h either i.v. or orally as appropriate. The oral dose will be rounded for convenience to either the 200 mg or 400 mg tablet twice daily.
Interventions
intravenously or orally administered
Eligibility Criteria
You may qualify if:
