Cryptococcus

[-kok′əs]
a genus of encapsulated yeasts that reproduce by budding rather than by producing spores. Many nonpathogenic species of Cryptococcus are commonly found in the soil and on the skin and mucous membranes of people who are well. Certain pathogenic species exist. C. neoformans is the most important. See also fungus, yeast.

AMBITION is a multi-centre phase-III trial to determine whether short-course high-dose liposomal amphotericin (L-AmB, Ambisome) is as effective as 14-day amphotericin B-based therapy in averting all-cause mortality in HIV-associated cryptococcal meningitis.
The older adult may also present with atypical manifestations of meningitis, although cryptococcal meningitis in GCA patients has rarely been reported.
Cryptococcal meningitis also manifests meningitis symptoms in clinics; however, cerebral base and mater enhancement and hydrocephalus are usually not obvious or only non-enhanced colloid pseudocyst or slightly enhanced cryptococcal tumors are displayed, and sometimes expanded peripheral space of special Virchow vessels in cerebral base can be seen.
The India ink and cryptococcal antigen test were positive and the final diagnosis was confirmed by Cryptococcus neoformans culture growth.
In people and animals, the most likely route of cryptococcal infection is by inhalation of basidio-spores or desiccated yeast cells from the environment, although the exact mode of transmission is unknown.
The cerebrospinal fluid obtained (CSF) was positive for India ink stain and showed a cryptococcal antigen titer of 1:512.
The factors most associated with poor prognosis are: altered mental status, CSF opening pressure greater than 25 cm of water, cryptococcal antigen in CSF greater than 1: 512, culture positive for cryptococcus in organs other than the CNS, and absence of meningeal enhancement (6).
This case highlights the difficulties of managing severe cryptococcal disease.
To our knowledge, there are few reports of venous sinus dysplasia occurring concurrently with cryptococcal meningitis.
Regarding diagnostic options cryptococcal antigen testing is nearly 100% sensitive and 97-99% specific when serum sample was collected and 96-100% sensitive and 94-99% specific when CSF sample was collected.
Of rapid biochemical and immunodiagnostic tests, which can be performed on blood and/or cerebrospinal fluid, (17,18) the detection of cryptococcal capsular antigen by latex agglutination is one of the most helpful tests for fungi performed on a routine basis.
