Several reasons for this anomaly seem possible: some of these specimens could have contained cryptococci that required >48 hours to demonstrate growth; recent experience in the laboratory has shown that an additional 12% of cryptococcal isolates will be found only when cultures are incubated for 7 days.
These events raise the possibility of direct percutaneous inoculation or the possibility of translocation of the cryptococci from the GI site into the blood stream.
Clearance of cryptococci from cerebrospinal fluid (CSF), as measured by a new primary end point--the decline in CSF cryptococcal colony forming units (CFU) over time--occurred significantly more quickly in the amphotericin B/flucytosine patients (decrease of 0.54 log CFU/day), than in the amphotericin B-only patients (decrease of 0.31 log CFU/day), the amphotericin B plus fluconazole patients (decrease of 0.39 log CFU/day), or the triple therapy patients (decrease of 0.38 log CFU/day), the investigators found (Lancet 363[9423]:1764-67, 2004).
