Estudo comparativo do LCR de pacientes com neurocriptococose sem AIDS e com AIDS Comparison between CSF samples from AIDS and non-AIDS patients with neurocryptococcosis

The purpose of this research was to compare the CSF changes in AIDS and non-AIDS patients with meningoencephalitis caused by Cr. neoformans.

The results of this research allowed to conclude that the inflammatory changes in the CSF from AIDS patients showed a lower intensity compared to those non-AIDS patients. These results showed as well, that the CSF samples from non-AIDS patients always revealed some changes besides the yeast cells. In some samples of AIDS patients, however the unique change was the presence of the yeast. It was demonstrated also, that the presence of Cr. neoformans in CSF, not accompanied by any other change, may suggest that is a patient with AIDS.
